    Full Text Available A 1 1/2 reduced-gravity model is proposed to study the hydrodynamic and thermodynamic features of the coastal upwelling area of Cabo Frio (Rio de Janeiro-Brazil. The vertical structure of the model is described by an active layer overlaying a deep inert layer where the pressure gradient is set to zero. For the upper layer, the model includes the turbulent version of the momentum. continuity and heat equations. The conservation of heat is represented by a transport equation to describe the thermodynamic changes of the sea surface temperature (SST. The solution domain includes open boundaries in which weakly-retlective conditions are prescribed. Solutions are found numerically on a uniform grid and the fundamental equations are approximated by the finite difference method. Numerical experiments are performed to evaluate the dynamic response of the coastal area of Cabo Frio forced by uniform and non-uniform wind fields. The solutions differ considerably depending on the orientation of the winds. East and northeast winds correlate with colder waters in the zonal coastline of this area and the presence of tlows toward Cabo Frio correlates with north wind components. The proposed model is validated with the numerical simulation of an observed event of upwelling, where a time­-dependent and non-uniform wind ficld develops a SST pattern similar as the observations, particularly the extension of the cool water plume in south-west direction and the rapid time variation of the SST.Um modelo de gravidade reduzida de 1 1/2 camada é proposto para estudar as características hidrodinmicas e termodinmicas da área costeira de Cabo Frio (Rio de Janeiro ­Brasil.

    Full Text Available The effect of coastal upwelling on the evolution of the atmospheric boundary layer (ABL in Cabo Frio (Brazil is investigated. For this purpose, radiosounding data collected in two experiments made during the austral summer (upwelling case and austral winter (no upwelling case are analysed. The results show that during the austral summer, cold waters that crop up near the Cabo Frio coast favour the formation of an atmospheric stable layer, which persists during the upwelling episode. Due to the low SSTs, the descending branch of the sea-breeze circulation is located close to the coast, inhibiting the development of a mixed layer mainly during the day. At night, with the reduction of the land-sea thermal contrast the descending motion is weaker, allowing a vertical mixing. The stable ABL favours the formation of a low level jet, which may also contribute to the development of a nocturnal atmospheric mixed layer. During the austral winter, due to the higher SSTs observed near the coast, the ABL is less stable compared with that in the austral summer. Due to warming, a mixed layer is observed during the day. The observed vertical profiles of the zonal winds show that the easterlies at low levels are stronger in the austral summer, indicating that the upwelling modulates the sea-breeze signal, thus confirming model simulations.

    Mercury (Hg) is considered a global pollutant, and the scientific community has shown great concern about its toxicity as it may affect the biota of entire systems, through bioaccumulation and bioamplification processes of its organic form, methylmercury (MeHg), along food web. However, few research studies deal with bioaccumulation of Hg from marine primary producers and the first-order consumers. So, this study aims to determine Hg distribution and concentration levels in phytoplankton and zooplankton in the Cabo Frio Bay, Brazil, a site influenced by coastal upwelling. The results from Hg speciation analyses show that inorganic mercury Hg(II) was the predominant specie in plankton from this bay. The annual Hg species distribution in plankton shown mean concentration of 2.00 ± 1.28 ng Hg(II) g(-1) and 0.15 ± 0.08 ng MeHg g(-1) wet weight (phytoplankton) and 2.5 ± 2.03 ng Hg(II) g(-1) and 0.25 ± 0.09 ng MeHg g(-1) wet weight (zooplankton). Therefore, upwelling zones should be considered in the Hg biogeochemical cycle models as a process that enhances Hg(II) bioaccumulation in plankton, raising its bioavailability and shelf deposition.

    An one-dimensional atmospheric second order closure model, coupled to an oceanic mixed layer model, is used to investigate the short term variation of the atmospheric and oceanic boundary layers in the coastal upwelling area of Cabo Frio, Brazil (23 degrees Celsius S, 42 degrees Celsius 08' W). The numerical simulations were carried out to evaluate the impact caused by the thermal contrast between atmosphere and ocean on the vertical extent and other properties of both atmospheric and oceanic boundary layers. The numerical simulations were designed taking as reference the observations carried out during the passage of a cold front that disrupted the upwelling regime in Cabo Frio in July of 1992. The simulations indicated that in 10 hours the mechanical mixing, sustained by a constant background flow of 10 m s-1, increases the atmospheric boundary layer in 214 m when the atmosphere is initially 2 K warmer than the ocean (positive thermal contrast observed during upwelling regime). For an atmosphere initially -2 K colder than the ocean (negative thermal contrast observed during passage of the cold front), the incipient thermal convection intensifies the mechanical mixing increasing the vertical extent of the atmospheric boundary layer in 360 m. The vertical evolution of the atmospheric boundary layer is consistent with the observations carried out in Cabo Frio during upwelling condition. When the upwelling is disrupted, the discrepancy between the simulated and observed atmospheric boundary layer heights in Cabo Frio during July of 1992 increases considerably. During the period of 10 hours, the simulated oceanic mixed layer deepens 2 m and 5.4 m for positive and negative thermal contrasts of 2 K and -2 K, respectively. In the latter case, the larger vertical extent of the oceanic mixed layer is due to the presence of thermal convection in the atmospheric boundary layer, which in turn is associated to the absence of upwelling caused by the passage of cold fronts

    The Cabo Frio region in the state of Rio de Janeiro, southeast coast of Brazil, is characterized by a local coastal upwelling system and converging littoral sediment transport systems that are deflected offshore at Cabo Frio, as a consequence of which a thick cross-shelf sediment deposit has developed over time. To investigate the evolution of this muddy deposit, geophysical, sedimentological and geochemical data from four sediment cores (3.8-4.1 m in length) recovered in water depths between 88 and 141 m were analyzed. The high-resolution seismic data show variable sediment thicknesses ranging from 1 to 20 m, comprising two sedimentary units separated by a high-impedance layer at a depth of about 10 m below the seafloor at the coring sites. According to the available age datings, the upper sedimentary unit is late Pleistocene to Holocene in age, whereas the lower unit (not dated) must, by implication, be entirely Pleistocene in age. The boomer-seismic reflection signal can be divided into three echo-types, namely transparent (inner shelf), stratified (middle shelf) and reflective (outer shelf), each type seemingly related to the local sediment composition. The upper 4 m of the upper sedimentary unit is dominated by silty sediment on the middle shelf, and by upward-fining sediments (silty sand to sandy silt) on the inner and outer shelf. The downcore trends of P-wave velocity, gamma-ray density and acoustic impedance are largely similar, but generally reversed to those of water and organic carbon contents. Total organic carbon contents increase with decreasing mean grain size, periodic fluctuations suggesting temporal changes in the regional hydrodynamics and primary productivity fuelled by the local upwelling system. The reconstruction of sedimentation rates in the course of the Holocene is based on 35 AMS age datings of organic material recovered from variable downcore depths. These range from a maximum of 13.3 cm/decade near the base of the inner shelf core (7

    Full Text Available We know little about animal communities in seagrass beds in the southeast Atlantic. The aim of the current study was to characterize and quantify the mollusk assemblages within these unique tropical seagrass habitats at a spatial scale fine enough to relate change in assemblage structure to gradients in exposure to air/depth. The study was carried out off Cabo Frio, Southeast Brazil. A 1250 m² area vegetated by the seagrass Halodule wrightii was defined (50 m parallel to the shoreline × 25 m distance from the shore margin. Twenty-six transects were established and the sampling carried out in order to characterize and to quantify the associated mollusk fauna. The mollusk assemblage presented overall density, density of key species and mean richness which increased systematically along the onshore-to-offshore gradient. Furthermore over the short spatial distance of the study the mollusk assemblage changed sufficiently for ordination to detect different assemblages.Há pouco conhecimento sobre a comunidade animal em bancos de fanerógamas marinhas no Atlântico sudeste. O presente estudo teve como objetivo caracterizar e quantificar assembléias de Mollusca nesses habitats únicos, utilizando uma escala espacial sensível suficiente para relacionar mudança na estrutura da assembléia aos gradientes em exposição ao ar/profundidade. O estudo foi realizado em Cabo Frio, no sudeste do Brasil. Delimitou-se uma área de vegetação de Halodule wrightii de 1250 m² (50 m paralelo ao costão × 25 m distância da orla. Foram estabelecidos 26 transectos e realizada a amostragem, de modo a caracterizar e quantificar a malacofauna. A assembléia apresentou uma densidade, densidade de espécies chaves e riqueza média que aumentou sistematicamente ao longo do gradiente orla-mar. Além disso, em escala espacial curta, a assembléia de Mollusca mudou suficientemente que, através de uma ordenação, se detectou diferenças entre assembléias.

    Sella, Silvia M.; Neves, Alessandra F.; Moreira, Josino Costa; Silva-Filho, Emmanoel V.

    In this work total suspended particulate (TSP) was collected during a year, in two municipalities located in a coastal region of Rio de Janeiro State, Southeast, Brazil, from February 2004 to January 2005. Two sites were chosen: site 1 located in front of the sea and representative of sea salt spray influence; site 2 in a tall booth of a highway representing vehicle exhaust influence. Samples were collected in glass fibre filters using Hi-Vol samplers and stored. 1/8 of those loaded filters were cut and digested in a microwave oven. The extract obtained was used to determine metal Ca, Cu, Mo, Mn, Ti, V, Zn and K concentration in the atmosphere. The results showed that TSP levels in site 1 (23.1-659 μg m -3) was higher than in site 2 (24.5-55.6 μg m -3) due to marine aerosol which is responsible for particle emissions with higher diameter. Vanadium was the only element studied whose concentration were higher in site 1 (0.840-20.9 ng m -3) compared to site 2 (0.655-7.07 ng m -3). The highest vanadium concentrations in site 1 were obtained during upwelling events, with NE winds predominance at high speed, which indicates the influence of this phenomena in V presence in the atmosphere. Principal components analysis was able to identify atmospheric particulate sources distributed in four factors. In site 1, those factors explain 86.5% of total data variance and indicate two sources: continental and marine. In site 2, those factors explain 89.2% of total data variance and indicate that vehicle exhaust is the main metals source in the atmosphere.

  8. Particle Fluxes and Bulk Geochemical Characterization of the Cabo Frio Upwelling System in Southeastern Brazil: Sediment Trap Experiments between Spring 2010 and Summer 2012

    Full Text Available Physical and biogeochemical processes in continental shelves act synergistically in both transporting and transforming suspended material, and ocean dynamics control the dispersion of particles by the coastal zone and their subsequent mixing and dilution within the shelf area constrained by oceanic boundary currents, followed by their gradual settling in a complex sedimentary scenario. One of these regions is the Cabo Frio Upwelling System located in a significantly productive area of Southeastern Brazil, under the control of the nutrient-poor western boundary Brazil Current but also with a wind-driven coastal upwelling zone, inducing cold-water intrusions of South Atlantic Central Water on the shelf. To understand these synergic interactions among physical and biogeochemical processes in the Cabo Frio shelf, a series of four experiments with a total of 98 discrete samples using sediment traps was performed from November 2010 to March 2012, located on the 145 m isobath on the edge of the continental shelf. The results showed that lateral transport might be relevant in some cases, especially in deep layers, although no clear seasonal cycle was detected. Two main physical-geochemical coupling scenarios were identified: singular downwelling events that can enhance particles fluxes and are potentially related to the Brazil Current oscillations; and events of significant fluxes related to the intrusion of the 18°C isotherm in the euphotic zone. The particulate matter settling in the Cabo Frio shelf area seems to belong to multiple marine and terrestrial sources, in which both Paraiba do Sul River and Guanabara Bay could be potential land-sources, although the particulate material might subject intense transformation (diagenesis during its trajectory to the shelf edge.

    Crystal size distribution (CSD) has been constrained in plagioclase in two mafic dykes of the Conchas Beach and one at the Lagoinha Beach in the Cabo Frio-Buzios NE-trending dyke swarm. At contact with the metamorphic basement the texture is fine-grained and microporphyritic and intergranular at the center of the larger dykes. Samples were collected at the margins and at the center of the dykes. The plagioclase average characteristic size (C) varies from 0.07 to 0.13 mm at the margins of the narrow dykes and from 0.09 to 0.20 mm at the margins of the larger dyke. At the center of the Lagoinha and Conchas dykes C varies from 0.19 ± 0.02 mm and 0.60 ± 0.07 mm respectively. The CSDs at the dyke margins are concave-up. At the center of the larger Conchas dyke (8.2 m), the CSD is log-linear, consistent with simple steady-state crystallization pattern. From the mineralogy the plagioclase phenocrysts have a high An content (bytownite-labradorite) than the groundmass grains (labradorite-andesine). At the margins olivine is richer in Fo than at the center, and respectively, pyroxene is richer in Ca. These results indicate that the chilled margin is more mafic than the center suggesting a normal chemical evolution in a cooling magma that ascended upward from depths by Newtonian to pseudoplastic flow. The concave-up CSDs probably depict heterogeneous crystallization rates possibly induced by depressurization during the magma ascent followed by rapid cooling. The log-linear CSD pattern at the center of the Conchas dyke (8.2 m width) is attributed to a higher residence time of the magma which favors the processes of chemical diffusion and textural re-equilibration. From the calculated cooling rates the larger Conchas dyke (8.2 m in width) would be completely crystallized (at ~ 900 °C) in about 2 years.

    Full Text Available Phytoplankton biomass, chemical parameters and hydrology were studied in a transect 101.6 km long off Cabo Frio (RJ, Southeast Brazil, during summer (December 29 to 31, 1991 and winter (June 27 to 30, 1992. Wind induced upwelling events are frequently observed in the area during summer, becoming rare during winter. By the summer cruise a bloom of phytoplankton was observed in surface, close to the coast, with chlorophyll concentrations reaching 25.55 mg Chl-a m-3, uncoupled from the cold, nutrient rich waters of South Atlantic Central Water (SACW, found below 40 m depth. During the winter cruise, the SACW raised at the surface waters in front of Cabo Frio depicting an upwelling event. However, in spite of high surface nitrate concentrations (up to 7.7 f.1M chlorophyll-a were lower than 2 mg Chl-a m-3. The phytoplankton biomass, meteorological and hydrological data suggest a probable upwelling event immediately before the summer cruise, and an ongoing one during winter time. Cluster analyses and principal component analyses (PCA were applied to summer and winter data, pointing out multidimensional fronts in the area during both seasons.A biomassa fitoplanctônica, parâmetros químicos e hidrologia foram estudadas em um transecto de 101,6 Km ao largo de Cabo Frio, (RJ Brasil, durante o verão (Dezembro 29 a 31, 1991 e inverno (Junho 27 a 30, 1992.

    Full Text Available Located on the northeast coast of the State of Rio de Janeiro, Brazil, Cabo Frio region has been considered a phytogeographical enclave, with a drier climate than the rest of this coast, a redoubt for the “caatinga” like vegetation, dominated by xeromorphic forests, Cactaceae and Bromeliaceae. In order to contribute to this discussion in a singular way, this work makes multivariate analysis of similarity of variables of the current climate, comparing Cabo Frio with its more humid surroundings and the “caatinga” of Brazilian northeast. We also analyze possible changes in regional palaeovegetation, using phytoliths as proxy. We conclude that Cabo Frio has a climate more similar to the “caatinga” than to its surrounding, and that the vegetation, from 13,000 years cal BP, did not present major changes.

  12. Is copper an inhibiting factor for primary production in the upwelling waters of Cabo Frio?

    2003-01-01

    Full Text Available The goal of the present work was to test the hypothesis that inorganic species of copper may inhibit primary production in upwelling waters from the Cabo Frio region. Water samples were collected from four different depths up to 50 m at three stations of Cabo Frio and nutrient concentration, pH, dissolved oxygen, alkalinity, seston, chlorophyll a, primary production, NPP, copper speciation, Cu(II and Cu(I and complexing capacity were determined. The results indicate that the rate of photosynthesis in nutrient rich waters with higher copper content and lower complexing capacity is significantly reduced. Cu(I made up 2-15% of the total copper, however, there was no evidence to suggest that the photochemical production of Cu(I affects NPP.

  13. Modern sedimentation in the Cabo Frio upwelling system, Southeastern Brazilian shelf

    2005-09-01

    Full Text Available The analyses of Uk'37 paleotemperatures and sedimentological parameters in box cores from the Cabo Frio upwelling zone, southeastern Brazil, were used to understand the modern sedimentation as well as to evaluate the role played by the upwelling process in the sedimentary patterns. Three box-cores located closer to the upwelling area show a general trend of cooling waters taking place in the last 700 years. Since the present upwelling is dependent on local and remote wind regime, a phase of dominating NE winds favors a more effective upward transport of the cold thermocline level South Atlantic CentralWater towards the coast. The intensification in the upwelling regime for the last ca. 700 years can be associated with the strengthening of the NE winds off the area and a possible increase of the Brazil Current mesoscale activity. Nevertheless, the lack of significant correlation of the paleotemperatures and most of sedimentological parameters indicate that upwelling is not the only sedimentation mechanism in the area. Also, the comparison of sedimentological parameters reveals that eventual temporal changes are superimposed by the geographical variability. Sedimentation rates vary from 0.26 mm.yr-1 to 0.66 mm.yr-1.As análises de Uk'37 paleotemperaturas e de parâmetros sedimentológicos em amostras de box-core da zona de ressurgência de Cabo Frio, sudeste do Brasil, foram usadas para compreender os processos de sedimentação moderna na área, bem como avaliar o papel desempenhado pela ressurgência no estabelecimento dos padrões sedimentológicos principais. Como observado em três box-cores localizados nas proximidades da área de ressurgência, é possível verificar uma tendência geral de resfriamento das águas nos últimos 700 anos (idade calibrada. Uma vez que o processo de ressurgência é dependente do regime de ventos local e remoto, uma fase de ventos predominantes de NE favorece um deslocamento mais efetivo das águas frias da

  17. The tectonic significance of the Cabo Frio Tectonic Domain in the SE Brazilian margin: a Paleoproterozoic through Cretaceous saga of a reworked continental margin

    Directory of Open Access Journals (Sweden)

    Renata da Silva Schmitt

    Full Text Available ABSTRACT: The Cabo Frio Tectonic Domain is composed of a Paleoproterozoic basement tectonically interleaved with Neoproterozoic supracrustal rocks (Buzios-Palmital successions. It is in contact with the Neoproterozoic-Cambrian Ribeira Orogen along the SE Brazilian coast. The basement was part of at least three continental margins: (a 1.97 Ga; (b 0.59 - 0.53 Ga; (c 0.14 Ga to today. It consists of continental magmatic arc rocks of 1.99 to 1.94 Ga. Zircon cores show a 2.5 - 2.6 Ga inheritance from the ancient margin of the Congo Craton. During the Ediacaran, this domain was thinned and intruded by tholeiitic mafic dykes during the development of an oceanic basin at ca. 0.59 Ma. After the tectonic inversion, these basin deposits reached high P-T metamorphic conditions, by subduction of the oceanic lithosphere, and were later exhumed as nappes over the basement. The Cabo Frio Tectonic Domain collided with the arc domain of the Ribeira Orogen at ca. 0.54 Ga. It is not an exotic block, but the eastern transition between this orogen and the Congo Craton. Almost 400 m.y. later, the South Atlantic rift zone followed roughly this suture, not coincidently. It shows how the Cabo Frio Tectonic Domain was reactivated as a continental margin in successive extensional and convergent events through geological time.

A partir de coletas mensais da ictiofauna, efetuadas com arrasto de porta, e da água, para a obtenção dos valores da temperatura, constatou-se a abundância de Etropus longimanus na região. Foram obtidas 653 fêmeas, em diferentes tamanhos e fases de desenvolvimento gonadal, o que nos permitiu a realização de um estudo sobre alguns aspectos da biologia reprodutiva desta espécie, como o tamanho da primeira maturação, o tipo de desova e a época de reprodução na região. Estimou-se um comprimento padrão médio em que a população das fêmeas apresentam 50% de probabilidade de estarem sexualmente maduras, de 75 mm; e o comprimento padrão médio em que todas estão aptas à reprodução, de 95 mm. Verificou-se que E. longimanus apresenta um desenvolvimento ovacitório sincrónico em mais de dois grupos, sugerindo a ocorrência de desova múltipla. Os resultados obtidos indicaram que a desova ocorreu desde o final da primavera, até o início do outono, com picos máximos no verão, quando registrou-se os valores da temperatura da água entre 13,3ºC a 18.7ºC, época predominante de ressurgência na região.As part of upwelling ecosystem project of the Cabo Frio region, 653 female of E. longimanus were obtained by monthly sampling from November 1986 to October 1988.

    Full Text Available Seahorses are found all over the world, in tropical and temperate coastal waters. The main aim of this study was to characterize the Hippocampus reidi populations in different depth and hydrodynamism categories in Arraial do Cabo, Rio de Janeiro state. The study was developed through scuba diving, with transects of 20m x 5m in two different depth layers: shallow, between 0 and 5m, and deep, between 5 and 10m. Through visual surveys, individuals were identified according to species, sex, and size (height – HT. The density of H. reidi varied according to depth and hydrodynamism. The highest mean depth was found in the Cabo Frio Island – Ponta do Anequin, as the lowest depth was found in Praia do Forno – Ponta D’água. There is no significant difference in the size of individuals nor in the sex ratio between the depth categories. The sex ratio of H. reidi in the population of Arraial do Cabo was 1:1. The results obtained indicated that the population characteristics are similar between the two depth layers.

    Full Text Available Imposex, an endocrine disruption phenomenon, is a biomarker of tributyltin (TBT exposure in marine gastropod populations. The occurrence and intensity of the syndrome in populations of the neogastropod Stramonita haemastoma were ascertained at nine sampling stations in October 2008 at Arraial do Cabo, a very important tourist resort in Rio de Janeiro state (Brazil and part of the Marine Extractive Reserve of Arraial do Cabo. The results obtained made it possible to evaluate the changes which had occurred since the last biomonitoring campaign, undertaken in 2001, at these same stations. Despite the ban on the use of TBT imposed by the Brazilian Navy in 2003, the controls on the use of this agent in Brazil resulting from the establishment of NORMAM 23 by the Navy in 2007 and the complete ban of organotin compounds in antifouling paint formulae by the IMO on a global scale in 2008, imposex was still detected. Instead of the expected reduction, an increase was observed in the areas affected by imposex. Furthermore, populations in the areas seriously affected by imposex in 2001 were absent in the 2008 sampling campaign. These results suggest an increase in TBT pollution in the study area, indicating the inefficacy of legislative measures.O imposex, um fenômeno de desregulação endócrina, é um biomarcador da exposição ao tributilestanho (TBT em populações de gastrópodes marinhos.

    Full Text Available Tal estudo teve por finalidade avaliar a velocidade e o transporte de volume da Corrente do Brasil, no seu trecho entre Cabo de São Tomé e Cabo Frio, fazendo uso do calculo geostrofico aplicado às secções amostradas durante os cruzeiros de abril e julho de 1970 e de julho de 1973. Foram localizados dois vórtices anticiclônicos, um durante o período de abril de 1970 e o outro durante julho de 1973. O valor máximo de velocidade da corrente na superfície foi de aproximadamente 70 cm/s e o transporte de volume foi de 14 x 10(6 m³/s. Foi possível também confirmar a existência de um meandro da Corrente do Brasil através da utilização de uma secção de BT (batitermografo mecânico associada a um registro contínuo de salinidade e de temperatura obtido com um termosalinografo.During the periods of April, July, 1970 and July, 1973, océanographic cruises were conducted in order to investigate the variability of the Brazil Current in the region between Cabo de Sao Tomé and Guanabara Bay. The geostrophic model of ocean circulation was applied using the hydrographie data collected during the cruise. From this study, a maximum velocity of 70 cm/sec and a volume trans port of 14 x 10(6 m³/sec were reported. The dynamic topography with reference to the 500 db surface, showed the presence of anticyclonic eddies during the periods of April, 1970, and July, 1973. The thermohaline structure within a meander of the Brazil Current is also presented utilizing the data coming from a continuous salinity and temperature recorder in conection with the data coming from a simultaneous BT section.

    Full Text Available Este trabalho apresenta o estado atual das pesquisas geológicas e petrográficas da brecha tectônica silicificada na área de Cabo Frio, RJ. A partir dos resultados, os autores propõem um modelo para o mecanismo de deslocamentos intermitentes das falhas. As zonas de brecha tectônica têm largura de 50 cm a 20 m e direção geral de NE-SW. Essas são cortadas por diques máficos do Eocretáceo. Os clastos são angulosos e caracterizados pela textura de autobrechação. A matriz é consolidada firmemente pela silicificação com disseminação de hematita, carbonatos e sericita. As zonas de brecha são distribuídas aleatoriamente em uma ampla área do Estado. Esta observação indica que a silicificação não está relacionada aos magmatismos locais de intrusões alcalinas do Cretáceo ao Eocenozóico. Uma idéia alternativa é o hidrotermalismo originado do gradiente geotérmico. De acordo com o gradiente geotérmico normal da região continental, de 25 a 30°C/km, a temperatura atribuída à faixa de profundidade de 6 a 8 km é de 180 a 220°C. Nesta condição, o H2 O presente aí comporta como líquido hidrotermal. Este tipo de hidrotermalismo, sem participação de magmas, é denominado hidrotermalismo amagmático. Quando ocorreu o terremoto, formou-se uma zona de cataclase. A água da superfície que infiltrou ao longo dessa e chegou a profundidade de 6 a 8 km transformouse em líquido hidrotermal amagmático. Conforme os reajustes de esforços e a conseqüente acomodação dos blocos rochosos crustais, o líquido hidrotermal foi pressionado e foi forçado a subir ao longo da zona de cataclase. Durante a ascensão e resfriamento do líquido hidrotermal, ocorreu a silicificação e consolidação da zona de cataclase. As brechas tectônicas silicificadas observadas na área estudada podem representar este fenômeno que ocorreu no tempo geológico. Através da silicificação e consolidação hidrotermal, o plano de falha transformou

    The diversity of burrowing sea anemones from Brazil is poorly known with only three species recorded. Metapeachia schlenzae sp. nov. is described from specimens collected in the intertidal zone of São Sebastião and Cabo Frio in the southeastern coast of Brazil. Metapeachia schlenzae sp. nov. is the second species described for the genus and the second haloclavid recorded from Brazil. A comparison between Metapeachia schlenzae sp. nov. and Metapeachia tropica, the type species of the genus, is included. The two valid species of Metapeachia differ in the morphology of the conchula, internal anatomy, cnidae and geographical distribution.

Afetou apenas indivíduos jovens, imaturos ou em maturação, com comprimentos totais entre 200 e 250 mm, atingindo um ou ambos os olhos, nas varias combinações possíveis. O caso estudado não se trata de catarata parasítica, não se verificando infestação do cristalino por larvas de trematodas, não sendo também causada por bactérias. Parecem existir dois caminhos do processo, caracterizando os tipos "radial" e "difuso". A análise dos padrões eletroforéticos de proteínas totais de cristalinos cataráticos permitiu determinar cinco fases de evolução, desde parcial inicial até total, durante as quais ocorrem alterações marcantes, tanto na concentração de proteínas totais solúveis nos extratos como na concentração relativa das oito frações proteicas que se grupam em quatro conjuntos nos padrões de cristalinos normais. Verificou-se aumento na concentração relativa dos conjuntos I (mais catódico e II e decréscimo dos conjuntos III e IV (mais anódico, com o desaparecimento das duas frações deste último conjunto nas fases finais do processo. Não foram constatadas alterações na concentração relativa dos quatro conjuntos, quando comparados cristalinos de indivíduos normais e cristalinos normais de indivíduos portadores, o que significa que a ocorrência de catarata em um dos olhos não causa quaisquer alterações naquele não afetado. Os resultados sugerem que a catarata se constitui em causa de mortalidade natural para a espécie nessa área e que seu desenvolvimento deve estar ligado a algum fator fisiológico ou metabólico induzido por condições ambientais.The presence of specimens of Micropogonias funieri suffering from cataracts was observed in the area occupied by the population I (Vazzoler, 1971. The frequency and distribution of these specimens were analysed and the electrophoretic patterns of soluble eye-lens proteins were determined. This cataract is not of parasitic origin and was rare in specimens from the coastal area. In the lagunar region it occurs mainly in specimens of the River Baguagu, from April to November. Only young fish (200 to 250 mm in imature or in maturation stages were affected. Two main pathways of evolution in the process seems to occur with a "radial" and a "difuse" type. The analysis of electrophoretic patterns showed 5 steps of evolution with remarkable alterations on the concentration of total soluble proteins as well as on the relative concentration of 8 proteic fractions grouped in 4 agregates in electropherograms, There is an increase in the relative concentration of the agregate I (more cathodic and II, and a decrease of the III and IV (anodic with the disappearance of the last two fractions of the latter in the final stages of the process. No alterations were determined in the relative concentrations of these agregates when comparing eye-lens of normal specimens with normal eye-lens of affected fish suggesting that the occurence of cataract in one eye does not cause any alteration in the normal eye. The results suggest that cataract may be the cause of natural mortality in the area, and its incidence may be due to a physiological or metabolic factor induced by environmental conditions.

    refers to the coastal zone between the Amapa Grande River and Araguari River, including Maraca Island and the Oriental lacustrine Belt. Westward the island, at least three paleolevels of clays with roots in life position suggests regressive/transgressive events. Extraordinaty paleodrainage network beginnig at the continent and recognized at the insular portion suggests links with the paleochannels found at the continental shelf. The Oriental Belt of lakes is located close to the coastline, at Cabo Norte. It main feature is a mud lump approximately 10 Km ratio, well recognized at the remote sensing. It shows similar evolutionary processes with Araguari River, dating from XIX century, when this river had two mouths defined by the Carpori Island. The reasons of the deactivation are still unknowed, but, this rapid morphological evolution indicates short time colmatation processes that can be linked to tectonic regional processes. On the other hand, the Cabo Norte feature consolidation may impose changes in the sedimentation processes yielding space reduction over the coastal plain accumulation, diminishing of the solid and liquid fluvial discharge and promoting the availability of the local sediment transport over the littoral. The investigation of these processes requires an integrated coastal plain-continental shelf morphological study applying adequate techniques for modification studies and dating ages over short geological time frame, in century scale level.

    question du tourisme et des déterminants historiques et géographiques de la région dans laquelle il se situe. La comparaison entre la gestion du Parc National de la Vanoise et celle du Parc National de Cabo Orange montre que les deux modèles de gestion et leurs contextes géopolitiques et environnementaux sont différents. D’une part, la France est bien plus peuplée et sa biodiversité est anthropisée. Par ailleurs, le Brésil est un pays formé d’espaces ouverts dans lesquels la biodiversité résulte, majoritairement, d’un processus évolutif naturel. La méthodologie retenue s’est servie du travail de terrain et d’une révision bibliographique de la littérature. En conclusion, la gestion du Parc National de la Vanoise tente de concilier développement régional et préservation des patrimoines naturels et culturels, alors que le Parc National de Cabo Orange protège la biodiversité dans sa forme la plus intacte possible.This article compares the management of two national parks: Cabo Orange National Park, in Brazil, and Vanoise National Park, in France. The regions in which these two national parks are located - the Brazilian Amazon and the French Alps, respectively - have an important global ecological value. Both Cabo Orange National Park and the Vanoise National Park have rare and remarkable ecosystems and, due to the complexity of their interactions, are threatened by global changes. The Cabo Orange National Park is presented in its regional context and its tourism. The Vanoise National Park is analyzed from the standpoint of tourism and France´s historical and geographical determinants. The comparison between the management of the Vanoise National Park and the Cabo Orange National Park shows that conservation requirements are similar, but their geopolitical and environmental contexts are different. On the one hand, France is more populous and its biodiversity is vastly impoverished. On the other hand, Brazil is a country of open spaces where

  12. Successional trajectory of the fouling community on a tropical upwelling ecosystem in southeast Rio de Janeiro, Brazil

    Full Text Available Abstract The present study describes the successional trajectory of the fouling community in the upwelling region of Cabo Frio in southeastern Rio de Janeiro, Brazil. For 12 months, five PVC panels were sampled monthly by underwater photography to record the percent cover of fouling organisms, which allowed for the evaluation of the successional process through functional groups. The variability in the composition of the fouling community increased throughout the successional trajectory, creating a mosaic pattern. The identification of two associations after a year of observation, with one characterized by filamentous algae, Hydrozoa and Cirripedia and another mainly by articulated calcareous algae, shows that divergent trajectories can be observed even under the same environmental conditions. As an important seasonal factor of the local oceanographic characteristics, the upwelling events allowed for an environmental heterogeneity, and rejecting the classic orderly and directional succession model.

    In recent decades, Oceanography has been using a variety of radionuclides as tracers to understand the ocean dynamic processes, handling and disposal of sediments of seabed. In this context, the determination of natural radionuclides distributions ({sup 238}U, {sup 232}Th and {sup 40}K) has been carried out with sediments samples from the shelf and upper slope off Southeast Brazil using a gamma spectrometry technique. The samples were sliced into strata of 2 cm, dried, ground and properly packed to be analysed. The concentration of activities was performed in a hyperpure Ge detector with a resolution of 1,9 keV for the peak of 1332,3 keV of {sup 60}Co, model GEM50P by EGG and ORTEC. The study area is located between latitudes 28 deg 40'S and 23 deg 00'S and extends from Cabo Frio (RJ) to Cabo de Santa Marta Grande (SC). The activity concentrations varied from 0,6 to 52,8 BqKg{sup -1} for {sup 238}U, from 1,6 to 50,9BqKg{sup -1} for {sup 232}Th and from 65,4 to 873,3 BqKg{sup -1} for {sup 40}K. From these results it is possible to establish a correlation between the depositional area dynamics and the samples size parameters. (author)

    Major sand trends were identified in the Frio Formation, Upper Texas Gulf Coast as part of the evaluation of its potential for producing geothermal energy. Electrical logs from 465 wells spaced 5 to 10 miles apart were used in the study. Maps illustrating total net sand and total sand percentage of the Frio Formation are included. It was found that subsurface fluid temperatures of greater than 250/sup 0/F occur in the Frio sand bodies up to 100 ft thick downdip of the high-sand trends. LA broad band in Brazoria and Galveston Counties was delineated as having geothermal potential. (JGB)

    of the thermal structure and to locate the Brazil Current flow both north and south of the seamount chain at 20º30'S. Dining the survey, remote sensing satellite data were also obtained on several occasions to assist in the delineation of the surface thermal structure. A 23ºC thermostad was observed along most sections. Along sections with stronger baroclinic signatures, such as the one in Cabo Frio, the thermostad seems to be pinched off somewhat similar to the pinching off the 18ºC water in the Gulf Stream North wall. The current structure and volume transports, relative to the 500 dbar isobaric surface, were calculated using both hydrographie station data and the closely spaced XBT measurements. A comparison of these results, for the data observed along the section of Cabo Frio, indicates that some details of the geostrophic currents are lost when the hydrographie data are used; the corresponding volume transports agree within 17% (33 Sv using hydrographie data against 2.8 Sv using XBT data. A volume transport budget, obtained through the transport computation along all sections between 19º and 22ºS, indicates that the Brazil Current appears to flow through the passage between the most inshore banks and not to the east. The net volume transport (2.9 Sv is in close agreement with the Cabo Frio section volume transport, where the total flow of the Brazil Current was supposedly bracketed by the station sampling.

    We present a magnetic survey conducted in the offshore region between Cabo da Roca and Sesimbra (mouth of Tagus River, Portugal). Strong magnetic anomalies are recognized in this area since a first marine survey in 1958 (Allan, 1965) and by further aeromagnetic survey (c.f. Silva et al, 2000). The anomalies have been linked to Cretaceous magmatic events related to the Upper Cretaceous Sintra magmatic complex and Lisbon volcanic complex, but their geometry and extension has yet not been resolved. The aim of the present survey was to unravel the location, geometry and type of the magnetic sources, thus contributing for the characterization of the main magmatic and tectonic features in the region. The survey was conducted in two legs (October 2014 and June 2015), consisting of 27 lines and 6 tielines, extending up to 40 km from the coast. The line spacing was 1 mile for the main lines and 5-6 miles for the tielines. The bathymetry of the surveyed area varies from very shallow (about 10 m) to near 3000 m. Total field was measured with a G-882 Cesium marine magnetometer of Geometrics (self-oscillating split-beam Cesium vapor), with frequency of acquisition of 10 Hz. Layback was real-time corrected using the acquisition software. Noise was removed by despike in Magpick software (Geometrics), and further processing was done using Oasis montaj (Geosoft) software. Data were subtracted of IGRF values and levelled by tielines to retrieve the final map of anomalies. Several punctual and linear anomalies with varying amplitude and wavenumber were identified, which cannot be explained by bathymetric variation; therefore they must then be due to the presence of higher susceptibility, likely volcanic rocks, and to structural inheritance associated with rifting and Alpine orogeny. The highest anomaly corresponds to the Cabo Raso positive magnetic anomaly, with maximum and minimum of 2800 nT and -1350 nT, respectively. This anomaly, already surveyed in 1958, has been compared to a

    We present the multibeam bathymetry and derived maps of the southeast Iberian margin from Cabo de Palos to Cabo de Gata, 37º35'N to 35º45'N and 2º10'W to 0º20'E, from the coastline down to the Algero-Balearic abyssal plain at depths exceeding 2600 m. The edition of of the maps is carried out within the Complementary Action VALORPLAT ("Scientific valorisation of multibeam bathymetry data from the Spanish continental shelf and slope"), funded by the Spanish Ministry of Economy and Competitivity. The multibeam bathymetry data of the slope and abyssal plain were obtained during different surveys in 2004, 2006 and 2007 on board R/V Vizconde de Eza with a Simrad EM300 multibeam echo-sounder as part of the CAPESME Project, a collaboration between the Spanish Institute of Oceanography (IEO) and General Secretariat of Fisheries (SGP), primarily aiming at creating maps of the fishing grounds of the Mediterranean continental margins of Spain. Multibeam bathymetry data from the continental shelf were obtained within the ESPACE project, also in a cooperative frame between IEO and SGP. The map series is constituted by a general map at 1:400,000 scale and 14 detailed maps at 1:75,000 scale, which include inset maps on slope gradients and seafloor nature (rock or sediment type), the later obtained with rock dredges and Shipeck sediment dredges. Both the detailed maps and the general map are available in paper print, and the whole collection is also distributed in an edited USB. The geological features displayed in the different maps include the continental shelf, with abundant geomorphic features indicative of past sea-level changes, the continental slope carved by the Palos, Tiñoso, Cartagena Este, Cartagena Oeste, Águilas, Almanzora, Alias, Garrucha and Gata submarine canyons, the Mazarrón, Palomares and Al-Mansour escarpments, the Abubácer, Maimonides and Yusuf ridges, the Águilas and Al-Mansour seamounts, and the Algero-Balearic abyssal plain where prominent

    Hydrologic hydrochemical investigations were conducted to determine the long-term fate of hazardous chemical waste disposed in the Texas Gulf Coast Tertiary Frio Formation by deep-well injection. Three hydrologic regimes exist within the Frio Formation: a shallow fresh to moderately saline water section in the upper 3,000-4,000 ft; an underlying 4,000-5,000 ft section with moderate to high salinities; and a deeper overpressured section with moderate to high salinities. The complexity of the hydrologic environment is enhanced due to extensive depressurization in the 4,000-8,000 ft depth interval, which presumably results from the estimated production of over 10 billion barrels of oil equivalent and associated brines from the Frio in the past 50 years. Because of the higher fluid density and general depressurization in the brine hydrostatic section, upward migration of these brines to shallow fresh groundwater should not occur. Depressurized oil and gas fields, however, may become sinks for the injected chemical wastes. Water samples appear to be in approximate oxygen isotopic equilibrium with the rock matrix, suggesting that active recharge by continental waters is not occurring. In the northern Texas Gulf Coast region salt dome dissolution controls water chemistry. In the central and southern Frio Formation, brines from the deeper geopressured section may be leaking into the hydrostatic section. The lack of organic acids and the alteration of Frio oils from samples collected from depths shallower than approximately 7,000 ft suggest microbial degradation of organic material. This has useful implications for degradation of injected chemical wastes and needs to be investigated further. 17 refs., 15 figs.

Êste último grupo de pacientes compreende 13 casos nos quais o sinal de Babinski ocorria unilateralmente e 8, nos quais ocorria bilateralmente. Os resultados permitiram verificar que o estímulo frio apenas ocasionalmente desencadeia a resposta que caracteriza o reflexo cutâneo plantar normal. Por outro lado, o estímulo frio possibilita com freqüência aproximadamente semelhante àquela observada para o estímulo táctil, a verificação do sinal de Babinski. Com freqüência a resposta que caracteriza o sinal de Babinski é mais nítida e duradoura quando se emprega o estímulo frio. Êsses dados mostram que o emprêgo do estímulo frio representa modalidade de semiotécnica útil para a elucidação de casos nos quais haja dúvidas quanto à presença de sinal de Babinski quando a pesquisa é feita segundo a técnica clássica. De fato, com o estímulo frio, observa-se tendência a refôrço do sinal de Babinski quando êle está presente; na sua ausência o mesmo tipo de estímulo não costuma determinar qualquer tipo de resposta.

    Hydrologic hydrochemical investigations were conducted to determine the long-term fate of hazardous chemical waste disposed in the Texas Gulf Coast Tertiary formations by deep-well injection. The study focused on the hydrostatic section of the Frio Formation because it is the host of a very large volume of injected waste and because large data bases of formation pressures and water chemistry are available. Three hydrologic regimes exist within the Frio Formation: a shallow fresh to moderately saline water section in the upper 3,000 4,000 ft (914 1,219 m); an underlying 4,000- to 5,000-ft-thick (1,219- to 1,524-m) section with moderate to high salinities: and a deeper overpressured section with moderate to high salinities. The upper two sections are normally pressured and reflect either freshwater or brine hydrostatic pressure gradients. Geopressured conditions are encountered as shallow as 6,000 ft (1,829 m). The complexity of the hydrologic environment is enhanced due to extensive depressurization in the 4,000- to 8,000-ft-depth (1,219- to 2,438-m) interval, which presumably results from the estimated production of over 10 billion barrels (208 × 106 m3) of oil equivalent and associated brines from the Frio in the past 50 yr. Because of the higher fluid density and general depressurization in the brine hydrostatic section, upward migration of these brines to shallow fresh groundwaters should not occur. Depressured oil and gas fields, however, may become sinks for the injected chemical wastes. Water samples appear to be in approximate oxygen isotopic equilibrium with the rock matrix, suggesting that active recharge of the Frio by continental waters is not occurring. In the northern Texas Gulf Coast region salt dome dissolution is a prime process controlling water chemistry. In the central and southern Frio Formation, brines from the deeper geopressured section may be leaking into the hydrostatic section. The lack of organic acids and the alteration of Frio oils

    Telemedicine and e-health have been suggested as one solution for closing the health disparity gap between the developed world and the developing world. Yet evidence is lacking from current successful programs in the developing world and, in particular, from sub-Saharan Africa. The primary objective of our study was to present the preliminary results of our efforts in building the Integrated Telemedicine and e-Health Program for Cabo Verde (ITeHP-CV), with an emphasis on initial utilization and results. This is a prospective study of data collected while we worked to establish a fully functional, integrated national telemedicine network and virtual education network in Cabo Verde. We used the International Virtual e-Hospital Foundation strategic approach known as "initiate-build-operate-transfer" over a 26-month period (November 2011-December 2013). We describe herein the five main pillars of this process that have been implemented: (1) capacity building; (2) network development and deployment of equipment; (3) implementation of clinical telemedicine; (4) implementation of activities related to continuing medical education, delivered from within the country and from abroad; and (5) establishment and use of the electronic virtual library. Based on comprehensive technical and medical assessment of the country's needs, 10 fully functional telemedicine centers in all nine inhabited islands of the Republic of Cabo Verde have been established. RESULTS are presented under the five main pillars of capacity building, network deployment, implementation of clinical telemedicine, implementation of continuing medical education activities, and establishment of the electronic virtual library. The ITeHP-CV has been successfully launched, and the initial results are encouraging. The continuity of the program and sustainability are primary goals once the program is transferred fully to the Ministry of Health of Cabo Verde. A long-term follow-up study is required in order to ensure

    Full Text Available Within the scope of the MAR-14 Project, part of the Brazil-Germany Bilateral Agreement in Marine Sciences, an oceanographic survey aboard the R/V Victor Hensen was carried out in Brazilian coastal waters between Santos (23º56'S and Rio de Janeiro (22º54'S, from January 15 to January 22,1991. In this article we report results of preliminary analyses of the hydrographic data collected with CTD, STD, Nansen bottles and XBT's. These preliminary results show intense stratification in the first 200 m depth, and the penetration of the Brazil Current deep into the continental shelf region. Two eddy-like features were detected. The first one, anticyclonic, was located in the northern part of the domain and confined to the uppermost 200 m. The second, a cyclonic vortex, was found a little to the southwest below 200 m and extending downwards to about 800 m depth. Water mass analyses based on T-S diagrams suggest that the interface between the South Atlantic Central Water (SACW and the Antarctic Intermediate Water (AIW is located at about 500 m depth. One important aspect of this study is that this was the first time a high resolution survey with a CTD probe was realized along the eastern Brasilian Coast, south of Cabo Frio.Como parte do projeto MAR-14, componente do Acordo Bilateral Brasil-Alemanha em Ciências Marinhas, uma campanha oceanógrafica a bordo do R/V Victor Hensen foi realizada em águas costeiras do Brasil entre Santos (23º56'S, de 15 a 22 de janeiro de 991.

    Full Text Available This work addresses the design and configuration of a Eulerian sediment trap mooring array, which was deployed at the shelf edge (zm ≈ 140 m 80 km off Cabo Frio, SE- Brazil (23° S. The site was subject to interplay between the Tropical Waters (TW of the Brazil Current (BC, intrusions from the South Atlantic Central Waters (SACW, which are the source of upwelling in the region, and other oceanographic processes. Detailed computations were used to optimize the total weight, buoyancy balance, and maximum acceptable tilt to avoid hydrodynamic bias in the trapping efficiency and array adaptation to the local oceanographic conditions with the assistance of Matlab and Muringa programs and Modular Ocean Model 4.0 (MOM; i.e., to assert the vertical distribution of the meridional current component. The velocity range of the current component was determined by short term measurements to be between 0.1 and 0.5 m/s. Projections led to a resulting minimum anchor weight of 456 kg. The necessary line tension was ascertained by using the appropriate distribution of a series of buoys along the array, which finally attained a high vertical load of 350 kg because of the attached oceanographic equipment. Additional flotation devices resulted in a stable mooring array as reflected by their low calculated tilt (2.6° ± 0.6°. A low drag of 16 N was computed for the maximum surface current velocity of 0.5 m/s. The Reynolds number values ranged from 4 × 104 to 2 × 105 and a cone-trap aspect ratio of 1.75 was used to assess the trap sampling efficiency upon exposure to different current velocities.

    Full Text Available Cinco observações oceanográficas espaciais quase sinóticas, realizadas de janeiro de 1970 a fevereiro de 1971, na região entre o Cabo de São Tomé e a Baía de Guanabara, são usadas para descrever a circulação sazonal e as condições de fluxo da Corrente do Brasil próximo à plataforma continental. As velocidades relativas foram calculadas sobre superfícies isanostéricas, de acordo com o método sugerido por Montgomery (1937. A precisão do método foi analisada, com base na propagação dos erros instrumentais das medidas da temperatura, da salinidade e da profundidade sobre o volume específico e a aceleração potencial, obtendo-se uma precisão de cerca de ± 3,0 cm s-1, para a velocidade relativa, e um máximo de ± 2,5 Sv, para o transporte de volume através da secção transversal. As correntes geostróficas de superfície, calculadas com referência à superfície isanostérica de 100 cl ton-1, sao geralmente mais intensas através das secções a leste de Cabo Frio, onde elas atingem valores máximos (~90 cm s-1 na borda da plataforma continental durante o verão, e valores acima de 86 cm s-1 ocorrem no inverno, mais além, a distâncias da costa maiores do que 140 km. Os diagramas T-S mostram os detalhes da distribuição do fluxo nas classes características e o fato de que 50% do transporte total corresponde à Massa de Água Tropical, próxima da superfície isanostérica de 220 cl ton-1. As variações do transporte total na coluna de água, desde a superfície até a superfície isanostérica de referência, foram analisadas para estimar o transporte por unidade de largura.Five-nearly-synoptic spatial oceanographic observations, taken from January, 1970 to February, 1971, in the region between Cape of São Tomé and Guanabara Bay, are used to describe the seasonal circulation and flow conditions of the Brazil Current, close to the continental slope. The relative geostrophic velocities were calculated over isanosteric

    This study was done to assess the repeatability and uncertainty of time-lapse VSP response to CO2 injection in the Frio formation near Houston Texas. A work flow was built to assess the effect of time-lapse injected CO2 into two Frio brine reservoir intervals, the ‘C’ sand (Frio1) and the ‘Blue sand’ (Frio2). The time-lapse seismic amplitude variations with sensor depth for both reservoirs Frio1 and Frio2 were computed by subtracting the seismic response of the base survey from each of the two monitor seismic surveys. Source site 1 has been considered as one of the best sites for evaluating the time-lapse response after injection. For site 1, the computed timelapse NRMS levels after processing had been compared to the estimated time-lapse NRMS level before processing for different control reflectors, and for brine aquifers Frio1, and Frio2 to quantify detectability of amplitude difference. As the main interest is to analyze the time-lapse amplitude variations, different scenarios have been considered. Three different survey scenarios were considered: the base survey which was performed before injection, monitor1 performed after the first injection operation, and monitor2 which was after the second injection. The first scenario was base-monitor1, the second was basemonitor2, and the third was monitor1-monitor2. We considered three ‘control’ reflections above the Frio to assist removal of overburden changes, and concluded that third control reflector (CR3) is the most favorable for the first scenario in terms of NRMS response, and first control reflector (CR1) is the most favorable for the second and third scenarios in terms of NRMS response. The NRMS parameter is shown to be a useful measure to assess the effect of processing on time-lapse data. The overall NRMS for the Frio VSP data set was found to be in the range of 30% to 80% following basic processing. This could be considered as an estimated baseline in assessing the utility

    Full Text Available Resumo A economia, atualmente, é impulsionada pela alta competitividade, exigindo que os setores de produção e logística sejam ágeis, flexíveis e com capacidade de ação para a solução de dificuldades. A logística é de extrema importância para as operações das cadeias de alimentos perecíveis, como carnes, peixes, lácteos, frutas e produtos hortícolas, assim como para determinados produtos da indústria farmacêutica, como vacinas, biomedicamentos e hemoderivados, que necessitam do uso da cadeia do frio devido à sua perecibilidade. A temperatura é o fator mais importante para a conservação da qualidade e manutenção da vida útil destes produtos, sendo a refrigeração um dos métodos mais amplamente utilizados para retardar o desenvolvimento de vários fatores que conduzem à sua deterioração. Dentre os desafios para a melhoria de incertezas da cadeia do frio, há a mitigação de riscos de ruptura da mesma. Sabe-se que há variações inevitáveis das condições de conservação dos produtos durante as etapas da cadeia de frio, as quais causam alteração da vida útil de alimentos perecíveis. Seja no transporte ou nas câmaras frias de armazenagem, há flutuação de temperatura em torno da condição ideal, sendo que ainda hoje, na maioria dos sistemas, o monitoramento da temperatura é realizado por pouquíssimos sensores. Embora poucas tecnologias de monitoração de temperatura sejam utilizadas para inibir os riscos de perda de qualidade e obter a segurança alimentar, estas são utilizadas de forma independente, nos diferentes elos da cadeia logística do frio. Esses desafios têm impulsionado esforços de grupos de pesquisas de países desenvolvidos para o aperfeiçoamento de aplicações de rede de sensores sem fio (RSSF e de identificação por radiofrequência (RFID, com base em dispositivos sensores. Este trabalho aborda aspectos importantes da aplicação destas novas tecnologias, que são capazes de

    A unique set of high-quality downhole shallow subsurface well log data combined with industry standard 3D seismic data from the Alaminos Canyon area has enabled the first detailed description of a concentrated gas hydrate accumulation within sand in the Gulf of Mexico. The gas hydrate occurs within very fine grained, immature volcaniclastic sands of the Oligocene Frio sand. Analysis of well data acquired from the Alaminos Canyon Block 818 No.1 ('Tigershark') well shows a total gas hydrate occurrence 13 m thick, with inferred gas hydrate saturation as high as 80% of sediment pore space. Average porosity in the reservoir is estimated from log data at approximately 42%. Permeability in the absence of gas hydrates, as revealed from the analysis of core samples retrieved from the well, ranges from 600 to 1500 millidarcies. The 3-D seismic data reveals a strong reflector consistent with significant increase in acoustic velocities that correlates with the top of the gas-hydrate-bearing sand. This reflector extends across an area of approximately 0.8 km{sup 2} and delineates the minimal probable extent of the gas hydrate accumulation. The base of the inferred gas-hydrate zone also correlates well with a very strong seismic reflector that indicates transition into units of significantly reduced acoustic velocity. Seismic inversion analyses indicate uniformly high gas-hydrate saturations throughout the region where the Frio sand exists within the gas hydrate stability zone. Numerical modeling of the potential production of natural gas from the interpreted accumulation indicates serious challenges for depressurization-based production in settings with strong potential pressure support from extensive underlying aquifers.

The Cabo Frio region as indicated by its name is a place of low SST due to a local upwelling triggered by the Northeast trade winds, the northward flow of cool South Atlantic Central Water and vortex of the Brazilian current in the upper warm Tropical Water. Paleoceanographic conditions during the last 13000 years have been reconstructed based on two cores collected on the outer shelf. The studied proxies included mineral and heavy metal quantification, bulk organic matter characteristics and planktonic foraminifera. A first phase of sedimentation between 13000 and 7000 cal BP is characterized by high mineral content probably due to the lower sea level. SST reconstruction indicate cool and highly variable temperatures that were probably not related to upwelling events made difficult by the low sea level but to lower regional SSTs. This is in good agreement with observations of continental climate dryer in southwest Brazil with intense events of precipitation. A second phase between 7000 and 3000 cal BP shows higher SST indicating few occurrences of upwelling. Its may be due to the decrease of South Atlantic Convergence Zone (ZCAS) intensity linked to the lower summer insolation and the reduced monsoonal flux at that time. On the adjacent continent the decrease monsoon is evidenced by low lake levels and poorly developed forests. The third and last phase, post 3000 cal BP, is characterized by the onset of upwelling events that may be related to an intensification of the South American Monsoon and of the ZCAS activity leading to an increase of Northeast winds during summer which is typically the upwelling season. On the continent this period was marked by forest development. The transition at 3000 yrs BP is very late compared to other Holocene Record. Paleoclimate model

  9. Hydrologic-hydrochemical characterization of Texas Frio Formation used for deep-well injection of chemical wastes

    Hydrologic-hydrochemical investigations were conducted to determine the long-term fate of hazardous chemical waste disposed in the Texas Gulf Coast Tertiary formations by deep-well injection. The study focused on the hydrostatic section of the Frio Formation because it is the host of a very large volume of injected waste and because large databases of formation pressures and water chemistry are available. Three hydrologic regimes exist within the Frio Formation: a shallow fresh to moderately saline water section in the upper 3,000 to 4,000 ft (914 to 1,219 m): an underlying 4,000- to 5,000-ft-thick (1,219 to 1,524-m) section with moderate to high salinities: and a deeper overpressured section with moderate to high salinities. The upper two sections are normally pressured and reflect either fresh-water or brine hydrostatic pressure gradients. Geopressured conditions are encountered as shallow as 6,000 ft (1,829 m). The complexity of the hydrologic environment is enhanced due to extensive depressurization in the 4,000- to 8,000-ft-depth (1,219 to 2,438-m) interval, which presumably results from the estimated production of over 10 billion barrels (208 x 10 to the power of 6 cu m) of oil equivalent and associated brines from the Frio in the past 50 yrs. Because of the higher fluid density and general depressurization in the brine hydrostatic section, upward migration of these brines to shallow fresh ground waters should not occur. Depressured oil and gas fields, however, may become sinks for the injected chemical wastes.

    This Environmental Assessment (EA) has been prepared to provide the environmental input into the Division of Geothermal Energy's decisions to expand the geothermal well testing activities to include sites in the Frio Formation of Texas and Louisiana. It is proposed that drilling rigs be leased before they are removed from sites in the formation where drilling for gas or oil exploration has been unsuccessful and that the rigs be used to complete the drilling into the geopressured zone for resource exploration. This EA addresses, on a regional basis, the expected activities, affected environment, and the possible impacts in a broad sense as they apply to the Gulf Coast well testing activity of the Geothermal Energy Geopressure Subprogram of the Department of Energy. Along the Texas and Louisiana Gulf Coast (Plate 1 and Overlay, Atlas) water at high temperatures and high pressures is trapped within Gulf basin sediments. The water is confined within or below essentially impermeable shale sequences and carries most or all of the overburden pressure. Such zones are referred to as geopressured strata. These fluids and sediments are heated to abnormally high temperatures (up to 260 C) and may provide potential reservoirs for economical production of geothermal energy. The obvious need in resource development is to assess the resource. Ongoing studies to define large-sand-volume reservoirs will ultimately define optimum sites for drilling special large diameter wells to perform large volume flow production tests. in the interim, existing well tests need to be made to help define and assess the resource.

    The Oligocene Frio and Anahuac Formations were assessed as part of the 2007 U.S. Geological Survey (USGS) assessment of Tertiary strata of the U.S. Gulf of Mexico Basin onshore and State waters. The Frio Formation, which consists of sand-rich fluvio-deltaic systems, has been one of the largest hydrocarbon producers from the Paleogene in the Gulf of Mexico. The Anahuac Formation, an extensive transgressive marine shale overlying the Frio Formation, contains deltaic and slope sandstones in Louisiana and Texas and carbonate rocks in the eastern Gulf of Mexico. In downdip areas of the Frio and Anahuac Formations, traps associated with faulted, rollover anticlines are common. Structural traps commonly occur in combination with stratigraphic traps. Faulted salt domes in the Frio and Anahuac Formations are present in the Houston embayment of Texas and in south Louisiana. In the Frio Formation, stratigraphic traps are found in fluvial, deltaic, barrier-bar, shelf, and strandplain systems. The USGS Tertiary Assessment Team defined a single, Upper Jurassic-Cretaceous-Tertiary Composite Total Petroleum System (TPS) for the Gulf Coast basin, based on previous studies and geochemical analysis of oils in the Gulf Coast basin. The primary source rocks for oil and gas within Cenozoic petroleum systems, including Frio Formation reservoirs, in the northern, onshore Gulf Coastal region consist of coal and shale rich in organic matter within the Wilcox Group (Paleocene–Eocene), with some contributions from the Sparta Sand of the Claiborne Group (Eocene). The Jurassic Smackover Formation and Cretaceous Eagle Ford Formation also may have contributed substantial petroleum to Cenozoic reservoirs. Modeling studies of thermal maturity by the USGS Tertiary Assessment Team indicate that downdip portions of the basal Wilcox Group reached sufficient thermal maturity to generate hydrocarbons by early Eocene; this early maturation is the result of rapid sediment accumulation in the early

    The Frio Fluvial-Deltaic Sandstone oil play of South Texas has produced nearly 1 billion barrels of oil, yet it still contains about 1.6 billion barrels of unrecovered mobile oil and nearly the same amount of residual oil resources. Interwell-scale geologic facise models of Frio Fluvial-deltaic reservoirs are being combined with engineering assessments and geophysical evaluations in order to determine the controls that these characteristics exert on the location and volume or unrecovered mobile and residual oil. Progress in the third year centered on technology transfer. An overview of project tasks is presented.

    In this study 72 soil samples collected right at the surface were analyzed. They were collected at two work parcels located within the basin of the Mato Frio Creek (total drainage area = 10.6 km²) located in the municipality of Itauna, except for a small fraction in its northern part, which is located in the municipality of Serra Azul. Both municipalities are in the State of Minas Gerais, Brazil. The sampling period covers the time span from May 2014 to May 2015, with the purpose of observing on a monthly basis the variation in the activity of the radionuclide Beryllium-7 ({sup 7}Be, Eγ = 477.6 keV) along a one year hydrologic cycle, stressing the dry and rainy seasons. The objective of this investigation was to establish a baseline for the alteration pattern of the {sup 7}Be content in the soil in order to use these results for future estimates of rates of erosion or accreation in areas of interest within this basin. In order to measure the {sup 7}Be activity in the collected samples, a gamma spectrometer was used, composed of a hyperpure germanium detector with a relative efficiency of 50%. The results indicate a net trend towards a marked variation in the activity of {sup 7}Be in relative to the period of year within which the samples were collected, which in turn results in a reduction or increase in the values of the {sup 7}Be monthly inventory in the topsoil.

    Full Text Available Fifty-five specimens of bluefish, Pomatomus saltator (Linnaeus, 1766, collected at Cabo Frio (23ºS, 42ºW, State of Rio de Janeiro, Brazil, between March 1995 and November 1995, were necropsied to study their infracommunities of metazoan parasites. Sixteen species of metazoan parasites were collected. All fish were parasitized by one or more metazoan. The digeneans were the majority of the parasite specimens collected, with 44.2%, followed by the helminth larval stages (cestodes, acanthocephalans, and nematodes with 40.6%. The Simpson index for all parasite species was 0.097, indicating lack of dominance by any species in the parasite community. Microcotyle pomatomi Goto, 1899 showed the higher frequency of dominance and mean relative dominance. The parasite species of P. saltator showed the typical overdispersed pattern of distribution. The majority of parasite species showed positive correlation between the host's total body length and prevalence or parasite abundance. Two species, Brachyphallus parvus (Manter, 1947 and Phocanema sp. have differences in their prevalences and abundances in relation to sex of the hosts. The mean diversity in the infracommunities of P. saltator was H'=1.243±0.521, with correlation with the host's total length and without difference between male and female fish. The components of the parasite community of P. saltator showed overall positive association. All pairs confonned by ectoparasites and adult endoparasites species showed signiticant positive association or covariation between their abundances. Five pairs of endoparasites larval species showed positive association or covariation, and two pairs, showed negative association and covariation. The parasite community of P. saltator was dominated by species with high prevalence values, that composed a high number of associations, thus, is considered closer to the interactive type.

    The ecology and movements of seabirds are still inadequately understood, mainly because they can rarely be studied efficiently from land. The potential of Cabo Carvoeiro (Peniche, Portugal) for monitoring seabird movements from land is poorly known internationally, as few results from this site have been published in English. Here we present data from standardised counts in October 2012 and draw attention to recent organised seabird counts in Portugal. Despite unfavourable weather conditions ...

  5. Phylogenetic relationships of cone snails endemic to Cabo Verde based on mitochondrial genomes.

    Due to their great species and ecological diversity as well as their capacity to produce hundreds of different toxins, cone snails are of interest to evolutionary biologists, pharmacologists and amateur naturalists alike. Taxonomic identification of cone snails still relies mostly on the shape, color, and banding patterns of the shell. However, these phenotypic traits are prone to homoplasy. Therefore, the consistent use of genetic data for species delimitation and phylogenetic inference in this apparently hyperdiverse group is largely wanting. Here, we reconstruct the phylogeny of the cones endemic to Cabo Verde archipelago, a well-known radiation of the group, using mitochondrial (mt) genomes. The reconstructed phylogeny grouped the analyzed species into two main clades, one including Kalloconus from West Africa sister to Trovaoconus from Cabo Verde and the other with a paraphyletic Lautoconus due to the sister group relationship of Africonus from Cabo Verde and Lautoconus ventricosus from Mediterranean Sea and neighboring Atlantic Ocean to the exclusion of Lautoconus endemic to Senegal (plus Lautoconus guanche from Mauritania, Morocco, and Canary Islands). Within Trovaoconus, up to three main lineages could be distinguished. The clade of Africonus included four main lineages (named I to IV), each further subdivided into two monophyletic groups. The reconstructed phylogeny allowed inferring the evolution of the radula in the studied lineages as well as biogeographic patterns. The number of cone species endemic to Cabo Verde was revised under the light of sequence divergence data and the inferred phylogenetic relationships. The sequence divergence between continental members of the genus Kalloconus and island endemics ascribed to the genus Trovaoconus is low, prompting for synonymization of the latter. The genus Lautoconus is paraphyletic. Lautoconus ventricosus is the closest living sister group of genus Africonus. Diversification of Africonus was in allopatry

  6. Revitalizing a mature oil play: Strategies for finding and producing unrecovered oil in Frio Fluvial-Deltaic Sandstone Reservoirs of South Texas

    The Frio Fluvial-Deltaic Sandstone Play of South Texas is one example of a mature play where reservoirs are being abandoned at high rates, potentially leaving behind significant unrecovered resources in untapped and incompletely drained reservoirs. Nearly 1 billion barrels of oil have been produced from Frio reservoirs since the 1940`s, yet more than 1.6 BSTB of unrecovered mobile oil is estimated to remain in the play. Frio reservoirs of the South Texas Gulf Coast are being studied to better characterize interwell stratigraphic heterogeneity in fluvial-deltaic depositional systems and determine controls on locations and volumes of unrecovered oil. Engineering data from fields throughout the play trend were evaluated to characterize variability exhibited by these heterogeneous reservoirs and were used as the basis for resource calculations to demonstrate a large additional oil potential remaining within the play. Study areas within two separate fields have been selected in which to apply advanced reservoir characterization techniques. Stratigraphic log correlations, reservoir mapping, core analyses, and evaluation of production data from each field study area have been used to characterize reservoir variability present within a single field. Differences in sandstone depositional styles and production behavior were assessed to identify zones with significant stratigraphic heterogeneity and a high potential for containing unproduced oil. Detailed studies of selected reservoir zones within these two fields are currently in progress.

    Full text: The Neoproterozoic-Ordovician Central Ribeira Orogen, in SE Brazil, presents two contrasting tectonic domains in its southern portion: (a) The Arc Domain constituted of Neoproterozoic to Paleozoic magmatic rocks and low P-high T metamorphic para (Sao Fidelis Group) - and ortho- derived units (in Oriental Terrane); and (b) The Basement Domain, constituted of a Paleoproterozoic and Neoproterozoic medium P-high T metamorphic para (Palmital-Buzios Succession)- and ortho-derived units (in Cabo Frio Tectonic Domain). Our work focuses on paraderived rocks sequences from both domains. The provenance analysis using U-Pb and Lu-Hf in zircon grains is presented here as an effective tool to unravel the paleogeography and nature of the pre-collisional sedimentary basins. We performed 505 analyses (U-Pb) on detrital zircon grains and some metamorphic overgrowths from six paragneiss samples. Besides, 141 analyses (Lu-Hf) in six samples only on the detrital zircon grains domains. All samples present a main peak from Neoproterozoic sources (750-570 Ma) and the other minor peak in the Stenian/Tonian periods (1200-850Ma), this indicate an orogenic contribution for this basin. Scarce register from the Mesoproterozoic and two peaks in the Archean/Paleoproterozoic (2.6 and 1.9 Ga) are recognized as a contribution from an ancient continent. The Lu-Hf data reveals a juvenile source for the detrital zircon grains from Buzios Succession while Palmital and Sao Fidelis Group units show a main crustal signature for their detrital zircon population. Based on the U-Pb and Lu-Hf data presented here, plus petrological data, geological correlations, and compilation of data from literature, we propose a tectonic model for the origin of para-derived rocks from the eastern part of the Ribeira Orogen. Starting with an extensional environment of ca. 600 Ma in a back-arc basin (Buzios succession deposition) and continuing as an active margin between 570 and 550 Ma in the fore-arc and prism

    Currently, a watershed management plan is being developed for Cabo Rojo region in Southwest Puerto Rico. This project fills in major gaps for water quality data on the Rio Viejo, a tributary on the Guanajibio River. The Rio Viejo flows through the town of Cabo Rojo, a town of 51,245 people. The project has identified 5 sites along the river to track bacterial loads. In the tropics, Enterococcus faecalis is an important indicator for fecal contamination in surface waters as it does not reproduce as quickly soils as E. coli. A combination of EPA 1600 and 9230B from Standard Methods for the Examination of Water and Wastewater for identification of E. faecalis were utilized. The assay is a four step procedure that identifies the four criteria of bacteria in the group D Streptococcus system. The criteria require that the bacteria are Gram-positive cocci and Esculin-positive. There also must be growth in Brain Heart Infusion Broth at 35C and 45C as well as growth in Brain Heart Infusion broth + 6.5% NaCl. Further research will be conducted at North Carolina State University to ascertain the vertebrate species that is the source of the contamination through the use of qPCR.

    1983-01-01

    Detailed geological, geophysical, and engineering studies conducted on the Frio Formation have delineated a geothermal test well site in the Austin Bayou Prospect which extends over an area of 60 square miles. A total of 800 to 900 feet of sandstone will occur between the depths of 13,500 and 16,500 feet. At leat 30 percent of the sand will have core permeabilities of 20 to 60 millidarcys. Temperature at the top of the sandstone section will be 300/sup 0/F. Water, produced at a rate of 20,000 to 40,000 barrels per day, will probably have to be disposed of by injection into shallower sandstone reservoirs. More than 10 billion barrels of water are in place in these sandstone reservoirs of the Austin Bayou Prospect; there should be approximately 400 billion cubic feet of methane in solution in this water. Only 10 percent of the water and methane (1 billion barrels of water and 40 billion cubic feet of methane) will be produced without reinjection of the waste water into the producing formation. Reservoir simulation studies indicate that 90 percent of the methane can be produced with reinjection. 106 figures.

  18. Reactive transport modeling to study changes in water chemistry induced by CO2 injection at the Frio-I brine pilot

    2009-11-01

    To demonstrate the potential for geologic storage of CO{sub 2} in saline aquifers, the Frio-I Brine Pilot was conducted, during which 1600 tons of CO{sub 2} were injected into a high-permeability sandstone and the resulting subsurface plume of CO{sub 2} was monitored using a variety of hydrogeological, geophysical, and geochemical techniques. Fluid samples were obtained before CO{sub 2} injection for baseline geochemical characterization, during the CO{sub 2} injection to track its breakthrough at a nearby observation well, and after injection to investigate changes in fluid composition and potential leakage into an overlying zone. Following CO{sub 2} breakthrough at the observation well, brine samples showed sharp drops in pH, pronounced increases in HCO{sub 3}{sup -} and aqueous Fe, and significant shifts in the isotopic compositions of H{sub 2}O and dissolved inorganic carbon. Based on a calibrated 1-D radial flow model, reactive transport modeling was performed for the Frio-I Brine Pilot. A simple kinetic model of Fe release from the solid to aqueous phase was developed, which can reproduce the observed increases in aqueous Fe concentration. Brine samples collected after half a year had lower Fe concentrations due to carbonate precipitation, and this trend can be also captured by our modeling. The paper provides a method for estimating potential mobile Fe inventory, and its bounding concentration in the storage formation from limited observation data. Long-term simulations show that the CO{sub 2} plume gradually spreads outward due to capillary forces, and the gas saturation gradually decreases due to its dissolution and precipitation of carbonates. The gas phase is predicted to disappear after 500 years. Elevated aqueous CO{sub 2} concentrations remain for a longer time, but eventually decrease due to carbonate precipitation. For the Frio-I Brine Pilot, all injected CO{sub 2} could ultimately be sequestered as carbonate minerals.

    Full Text Available A produção comercial de mirtilos na América do Sul tem passado por mudanças importantes nos últimos anos, em função do aumento da oferta de frutos frescos dos principais países produtores, causando forte queda de preços em plena safra, entre os meses de dezembro e fevereiro. Uma alternativa para esta situação é a produção de mirtileiros de maturação precoce ou muito tardia, fora da época de meia-estação, caracterizada pelos menores preços da fruta. Em 2010, foram introduzidas no Brasil novas variedades de mirtileiros de baixa exigência em frio desenvolvidas pela Universidade da Flórida, que podem ser cultivadas em regiões quentes e apresentam uma frutificação mais precoce, quando comparadas com as variedades tradicionalmente cultivadas no Brasil. Essas novas variedades apresentam grande potencial para a produção precoce de mirtilos no País em regiões sem frio hibernal, aumentando significativamente a rentabilidade da cultura. Para viabilizar esta produção, é necessário validar estratégias de manejo para estas variedades, devido à falta de informação técnica sobre seu cultivo nas condições edafoclimáticas brasileiras. Atualmente, estäo sendo conduzidas as primeiras pesquisas fitotécnicas no Estado de Säo Paulo para avaliar o crescimento e a produção destas variedades na ausência total de frio, situação de ocorrência particular em poucos países produtores do mundo.

    Full Text Available Com o objetivo de investigar se o estrangulamento do caule de cafeeiros novos, observado em alguns anos de inverno rigoroso, poderia ser conseqüência do acúmulo de camadas de ar frio nas proximidades do solo, tratou-se com temperaturas baixas a haste de plantas com cêrca de seis meses de idade. O tratamento consistiu em se fazer circular salmoura refrigerada ao redor do caule, sem, entretanto, entrar em contato com êste. Obteve-se o estrangulamento com o emprêgo de vários tratamentos que incluiam temperaturas de - 2 a - 6º C. Uma planta tratada com temperatura de - 5 a - 7º C morreu duas semanas após o tratamento. Plantas tratadas por duas horas com as temperaturas de 0 a - 2º C não exibiram estrangulamento nem qualquer outro sintoma de anormalidade.A strangulation of the stem of young coffee plants a few inches above ground has been observed in some years after a cold winter. To know if this strangulation could be caused by the action of a layer of cold air that had settled over the surface of the soil as has been suggested (1, an experiment was carried out wich consisted of circulating cold water around the stem for a certain period of time. To accomplish this a special apparatus was mode using plexiglass. To obtain temperatures below the freezing point, pre-chilled salt water was used. To avoid an injurious direct contact of brine with the stem, this was wrapped with aluminum foil which was made waterproof. Two plants subjected to temperature treatments of 0° to - 2° C survived without damage. All treatments with temperatures below - 2° C resulted in strangulation and in the case of the coldest treatment used (- 5 to - 7° C in the death of the plant.

    Full Text Available O cedro australiano (Toona ciliata M. Roem é uma espécie difundida no Sudeste, Centro-Oeste e Nordeste do Brasil, onde alcança boa produtividade. Possui madeira de excelente qualidade para finalidades nobres. Entretanto, na região Sul do Brasil apresenta problemas de adaptação devido à ocorrência de geadas. O objetivo deste estudo foi verificar a tolerância ao frio e o potencial silvicultural de cedro-australiano em dois locais no Sul do Brasil. Os tratamentos consistiram de plantio puro de cedro-australiano e misto, com Mimosa scabrella e Eucalyptus benthamii em Lages, SC, e puro e sob Pinus taeda em Ibiam, SC. Durante dois anos após a implantação avaliou-se sobrevivência, danos por geada, bifurcação/brotação, altura total e diâmetro do colo. O cedro-australiano apresentou sérios danos pela geada no município de Lages, reduzindo drasticamente a sobrevivência e prejudicando as características silviculturais. O plantio do cedro-australiano sob pínus em Ibiam apresentou baixa taxa de mortalidade devido a geadas. O plantio puro nesta mesma região também apresentou baixa mortalidade, contudo, os efeitos das geadas foram consideráveis. O plantio de cedro-australiano não é indicado para as regiões com geadas intensas, contudo, em locais com geadas menos severas, o plantio sob pínus é uma alternativa potencial.

    The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, Fort Worth District; the City of Corpus Christi; the Guadalupe-Blanco River Authority; the San Antonio River Authority; and the San Antonio Water System, configured, calibrated, and tested a watershed model for a study area consisting of about 5,490 mi2 of the Frio River watershed in south Texas. The purpose of the model is to contribute to the understanding of watershed processes and hydrologic conditions in the lower Frio River watershed. The model simulates streamflow, evapotranspiration (ET), and groundwater recharge by using a numerical representation of physical characteristics of the landscape, and meteorological and streamflow data. Additional time-series inputs to the model include wastewater-treatment-plant discharges, surface-water withdrawals, and estimated groundwater inflow from Leona Springs. Model simulations of streamflow, ET, and groundwater recharge were done for various periods of record depending upon available measured data for input and comparison, starting as early as 1961. Because of the large size of the study area, the lower Frio River watershed was divided into 12 subwatersheds; separate Hydrological Simulation Program-FORTRAN models were developed for each subwatershed. Simulation of the overall study area involved running simulations in downstream order. Output from the model was summarized by subwatershed, point locations, reservoir reaches, and the Carrizo-Wilcox aquifer outcrop. Four long-term U.S. Geological Survey streamflow-gaging stations and two short-term streamflow-gaging stations were used for streamflow model calibration and testing with data from 1991-2008. Calibration was based on data from 2000-08, and testing was based on data from 1991-99. Choke Canyon Reservoir stage data from 1992-2008 and monthly evaporation estimates from 1999-2008 also were used for model calibration. Additionally, 2006-08 ET data from a U.S. Geological Survey

    Full Text Available O experimento foi desenvolvido no setor de floricultura do Departamento de Fitotecnia da Universidade Federal de Santa Maria – Santa Maria, RS, no período de novembro a dezembro de 2007 e teve como objetivo avaliar o efeito do armazenamento a frio e da desidratação sobre o enraizamento de estacas herbáceas de Dendranthema grandiflora, cultivares ‘Satllion’ e ‘Toon Hermans’, tratadas com Ácido Indol Butírico (AIB 0,1%. As estacas herbáceas foram coletadas no matrizeiro localizado no Setor de Floricultura, apresentando 6 cm de comprimento final, e foram então armazenadas a frio por diferentes períodos de tempo (0; 7; 14 e 21 dias, sendo que cada tratamento constou de 20 repetições. As estacas depois de tratadas com AIB 0,1% foram pesadas antes e após o armazenamento para obter o percentual de perda de umidade e, logo após, foram plantadas em bandejas de enraizamento contendo casca de arroz carbonizada e colocadas em estufa onde permaneceram 15 dias até sua avaliação. Para a avaliação do efeito da estocagem a frio e desidratação, foram realizadas as seguintes medições: comprimento total das raízes nas estacas e número de raízes por estaca. Os resultados obtidos neste trabalho mostraram que certo nível de frio é favorável ao enraizamento, porém este efeito deve ser observado quanto a cultivar e ao tempo de exposição das estacas às baixas temperaturas. Além disso, foi possível observar que a capacidade de formação e crescimento das raízes pelas estacas é um caráter varietal, o que determina um melhor desempenho das plantas.

    In 2009, Cabo Verde diagnosed the first dengue cases, with 21,137 cases reported and Aedes aegypti was identified as the vector. Since the outbreak, chemical insecticides and source reduction were used to control the mosquito population. This study aimed to assess the susceptibility of A. aegypti populations from Santiago, Cabo Verde to insecticides and identify the mechanisms of resistance. Samples of A. aegypti eggs were obtained at two different time periods (2012 and 2014), using ovitraps in different locations in Santiago Island to establish the parental population. F1 larvae were exposed to different concentrations of insecticides (Bacillus thuringiensis var israelensis (Bti), diflubenzuron and temephos) to estimate the lethal concentrations (LC90) and calculate the respective rate of resistance (RR90). Semi-field tests using temephos-ABATE(®) were performed to evaluate the persistence of the product. Bottle tests using female mosquitoes were carried out to determine the susceptibility to the adulticides malathion, cypermethrin and deltamethrin. Biochemical and molecular tests were performed to investigate the presence of metabolic resistance mechanisms, associated with the enzymes glutathione S-transferases (GSTs), esterases and mixed-function oxidases (MFO) and to detect mutations or alterations in the sodium channel and acetylcholinesterase genes. A. aegypti mosquitoes from Santiago exhibited resistance to deltamethrin, cypermethrin (mortality<80%) and temephos (RR90=4.4) but susceptibility to malathion (mortality≥98%), Bti and diflubenzuron. The low level of resistance to temephos did not affect the effectiveness of Abate(®). The enzymatic analysis conducted in 2012 revealed slight changes in the activities of GST (25%), MFO (18%), α-esterase (19%) and β-esterase (17%), but no significant changes in 2014. Target site resistance mutations were not detected. Our results suggest that the A. aegypti population from Santiago is resistant to two major

    Full Text Available The presence of Sanzos's goby, Lesueurigobius sanzoi (de Buen, 1918, off Cabo Raso, Portugal, is recorded for the first time. The biology of this population was studied using 11 samples collected between April 2000 and September 2001 at depths of 70-100 m on muddy and sandy bottoms. The females reach a standard length of 110 mm and the males 103 mm. It attains an age of 24 months, which equals two breeding seasons. The otoliths form two translucent rings each year, which corresponds to the winter growth and the reproduction period. Sanzo's gobies can be classified as prematur and standard individuals, according to whether the first breeding occurs before or after the first winter respectively. Standard individuals, which have an extended first growth, reach a longer length than prematur individuals, whose first growth is much shorter. Although discrete, sexual dimorphism was noticeable even outside the spawning season. The breeding season occurs between May and September/October with more than one spawning. The minimum length for which the maturity stage occurs is 64 mm, at an age of 0+. The feeding activity is quite constant throughout the year, and the diet consists predominantly of small crustacea and molluscs, although polychaets also feature commonly in its diet.

    This work presents the results of a combined study on the beach morphology and the evolution at short- and medium-term of the littoral between Ceuta and Cabo Negro (Morocco). It is an interesting sector showing a great increase of human occupation and coastal structures. The monitoring program allowed for the reconstruction of the beach morphological behavior and the seasonal changes. The studied beaches presented reflective profiles recording little seasonality, with the most notable morphological changes being strictly related to storms. Surf Similarity and Surf Scaling parameters highlighted the existence of intermediate and reflective beach states, characterized by plunging breakers. Aerial photographs and a satellite image have been geo-referenced and elaborated with GIS tools to reconstruct the short- and medium-term evolution of the littoral and the sediment transport pathways. The littoral showed important erosion at short- and medium-term related to a negative sedimentary budget because of offshore transport. Sand accumulation was recorded close to the main ports, i.e., Marina Smir and Marina Kabila. These port structures constituted impermeable, fixed limits, which divided the studied area into littoral cells. Other free, transit limits were also observed.

    Objectives We used an individual-based model to evaluate the effects of hypothetical prevention interventions on HIV incidence trajectories in a concentrated, mixed epidemic setting from 2011 to 2021, and using Cabo Verde as an example. Methods Simulations were conducted to evaluate the extent to which early HIV treatment and optimization of care, HIV testing, condom distribution, and substance abuse treatment could eliminate new infections (i.e., reduce incidence to less than 10 cases per 10,000 person-years) among non-drug users, female sex workers (FSW), and people who use drugs (PWUD). Results Scaling up all four interventions resulted in the largest decreases in HIV, with estimates ranging from 1.4 (95%CI:1.36–1.44) per 10,000 person-years among non-drug users to 8.2 (95%CI:7.8–8.6) per 10,000 person-years among PWUD in 2021. Intervention scenarios targeting FWS and PWUD also resulted in HIV incidence estimates at or below 10 per 10,000 person-years by 2021 for all population sub-groups. Conclusions Our results suggest that scaling up multiple interventions among entire population is necessary to achieve elimination. However, prioritizing key populations with this combination prevention strategy may also result in a substantial decrease in total incidence. PMID:25838121

    Full Text Available RESUMO Este trabalho apresenta os resultados de uma pesquisa experimental que objetivou estudar o comportamento mecânico de uma mistura betuminosa a frio sob efeitos de cargas estáticas e repetidas. Após a caracterização dos agregados e do ligante empregados na pesquisa, efetuou-se a mistura, a partir da dosagem Marshall, obtendo o teor de projeto equivalente a 8,5% de emulsão. Nesse teor de emulsão, moldaram-se várias amostras, que foram submetidas aos ensaios de módulo de resiliência, resistência à tração por compressão diametral e fadiga. A caracterização dos agregados e do ligante mostrou-se concordante com vários estudos, exceto o resíduo da peneiração, que não atendeu à exigência do IBP (1999. Para os ensaios com as misturas asfálticas, empregaram-se três corpos de prova, pesando cada um deles cerca de 1.200 g, compactados com 75 golpes em cada uma de suas faces. Observou-se que a estabilidade e a fluência Marshall de 620 kgf e de 4,20 mm, respectivamente, superaram o limite mínimo recomendado na especificação de serviço do DNIT (2010a. Com relação aos ensaios de módulo de resiliência e de resistência à tração por compressão diametral, obtiveram-se os valores de 1.616 MPa e 0,44 MPa, respectivamente, quando se verificou que os resultados foram bem inferiores aos encontrados em misturas a quente. Esse mesmo comportamento foi observado no ensaio de fadiga que, na maioria dos níveis de tensão aplicados, foi inferior a 1.000 aplicações do carregamento.

Su cronología es muy amplia y difícil de precisar, abarcando desde la época romana hasta la actualidad. Se ha hecho más incapié en el estudio de las cerámicas de época antigua a través de las cuales se puede datar, de momento, el inicio de la actividad marítima y comercial del fondeadero de Asturiaga entre la segunda mitad del siglo I a.C. y el siglo I d.C. teniendo en cuenta las ánforas Dressel 1 y la sigillata hispánica Dragendorf 29. Entre los siglos I y II los hallazgos van a ser más abundantes: sigillata hispánica, cerámica común, cerámica local, etc., lo que hace pensar en un gran desarrollo de la industria de cabotaje en el Golfo de Vizcaya. Las convulsiones del siglo III deben afectar a esta zona dado que no se ha podido datar con   seguridad ninguna pieza en este siglo. Se experimenta un aumento de los hallazgos en época tardía, siglo V en adelante (ánforas de las formas 77 y 82, cerámica local de grandes bordes peinados horizontales, etc.. De época moderna cabe destacar unos fragmentos de anforetas y botijuelas datables entre 1580 y 1850 y algunas piezas de cerámica esmaltada.

    Domestic fluvial-dominated deltaic (FDD) reservoirs contain more than 30 Billion barrels (Bbbl) of remaining oil, more than any other type of reservoir, approximately one-third of which is in danger of permanent loss through premature field abandonments. The U.S. Department of Energy has placed its highest priority on increasing near-term recovery from FDD reservoirs in order to prevent abandonment of this important strategic resource. To aid in this effort, the Bureau of Economic Geology, The University of Texas at Austin, began a 46-month project in October, 1992, to develop and demonstrate advanced methods of reservoir characterization that would more accurately locate remaining volumes of mobile oil that could then be recovered by recompleting existing wells or drilling geologically targeted infill. wells. Reservoirs in two fields within the Frio Fluvial-Deltaic Sandstone (Vicksburg Fault Zone) oil play of South Texas, a mature play which still contains 1.6 Bbbl of mobile oil after producing 1 Bbbl over four decades, were selected as laboratories for developing and testing reservoir characterization techniques. Advanced methods in geology, geophysics, petrophysics, and engineering were integrated to (1) identify probable reservoir architecture and heterogeneity, (2) determine past fluid-flow history, (3) integrate fluid-flow history with reservoir architecture to identify untapped, incompletely drained, and new pool compartments, and (4) identify specific opportunities for near-term reserve growth. To facilitate the success of operators in applying these methods in the Frio play, geologic and reservoir engineering characteristics of all major reservoirs in the play were documented and statistically analyzed. A quantitative quick-look methodology was developed to prioritize reservoirs in terms of reserve-growth potential.

  2. Spotlight: Brazil.

    Brazil is South America's largest country and home to nearly half of the continent's people. Despite solid economic growth, Brazil has one of the world's widest income disparities. In the early 1990s, nearly 40% of urban and 66% of rural Brazilians lived in poverty. The streets of Brazil's cities are home to a large population of street children. Although it is difficult to estimate, 10 million children and youths may be either homeless or making a meager living off of the streets. Street children may be linked to prostitution and drugs and be the targets or perpetrators of violence. Child labor is an issue in Brazil. Today an estimated 30% of rural children and 9% of urban children ages 10-13 work in the formal economy. In some rural areas, 60% of workers are ages 5-17. Child labor also contributes to Brazil's relatively low educational attainment levels. UNICEF estimates that around 1990 only 1/3 of all Brazilian children continued on to secondary school, compared to 74% and 47%, respectively, for the Latin America and Caribbean regions. Immunization rates among Brazil's children are rising but still lag slightly behind regional averages. The mortality rate for children under age 5 decreased dramatically from 181 deaths for every 1000 live births in 1960 to 61/1000 in 1994. During the same time period, the average number of children born to a woman during her lifetime dropped from 6.2 to 2.8. This fertility decline is related in part to increased access to and acceptance of family planning. Contraceptive prevalence, including traditional and modern methods, is around 66%, with female sterilization and the pill being the most popular methods. Brazil's abortion rates are high, despite laws limiting access to abortion services. One estimate suggests that about 30% of all pregnancies are terminated through abortion each year.

    The main aim of mineral potential mapping is to generate predictive maps showing the spatial distribution of a numerical index of favour ability for the presence of a mineral deposit of the type sought. We have studied the mineral favorability for epithermal gold deposits in the Cabo de Gata volcanic field in the Province of Almeria in Spain. Predictive maps deriving from the models suggest the presence of several potentially favourable zones. The performance of predictive maps is similar in most cases. Nevertheless, data-driven methods are able to capture more readily the spatial distribution of known gold occurrences in the area. (Author) 32 refs.

    Abstract Arthropod-borne viruses, such as Dengue (DENV), Chikungunya (CHIKV), and Zika (ZIKV), pose a challenge to public health, due to their worldwide distribution and large-scale outbreaks. Dengue fever is currently one of the most important diseases and it is caused by four serotypes of DENV and is mainly transmitted by the mosquito Aedes aegypti. It is estimated that 50–100 million cases are reported every year worldwide. More recently, CHIKV and ZIKV, which are also transmitted by Ae. aegypti, have caused epidemics in countries in the Caribbean region, the Pacific region, and Americas. Cabo Verde faced its first dengue outbreak in 2009, with more than 21,000 reported cases and four registered deaths. The epidemic was caused by DENV-3 transmitted by Ae. aegypti mosquitoes. In addition, the country faced a Zika outbreak with more than 7,500 notified cases from October 2015 to May 2016. In the present study, we conducted a survey in mosquito samples to detect arboviruses circulating in the local vector population. Collections were performed from November 2014 to January 2015, in the City of Praia, the capital of Cabo Verde, using aspirators and BG-sentinel traps. Samples were examined by multiplex Reverse Transcription-polymerase chain reaction. A total of 161 Ae. aegypti adult females were analyzed (34 pools) and from these samples, eight pools were found positive for DENV-2 and DENV-4. Our results revealed a very high natural infection rate in the vector population and showed two different serotypes co-circulating in the island that differ from the one detected in the 2009 outbreak in Cabo Verde.

    Full Text Available The Los Cabos corridor is one of the most dynamic tourism spaces in Mexico. In, around and towards this corridor, intense flows of tourists, migrants, merchandises and information takes place. Diverse in their territorial Impact as they are, most of them act as a link between the southernmost tip of the Baja peninsula and the state of California, in the United States. This is provoking a dissociation of this region of Mexico in its relation with the rest of the country that, to a certain extent, leads to a loss of national sovereignty.

    In the Herbeira massif, Cabo Ortegal Complex, Spain, a well exposed assemblage of deformed dunites and pyroxenites offers a unique opportunity to investigate key upper mantle tectonic processes. Four types of pyroxenites are recognized: clinopyroxenites with enclosed dunitic lenses (type-1), massive websterites (type-2), foliated and commonly highly amphibolitized clinopyroxenites (type-3) and orthopyroxenites (type-4). Field and petrological observations together with EBSD analysis provide new insights on the physical behavior of the pyroxenes and their conditions of deformation and reveal the unexpected journey of the Cabo Ortegal pyroxenites. We show that, during deformation, type-1 pyroxenites, due to their enclosed dunitic lenses, are more likely to localize the deformation than types-2 and -4 pyroxenites and may latter act as preferred pathway for fluid/melt percolation, eventually resulting in type-3 pyroxenites. All pyroxenite types display a similar response to deformation. Orthopyroxene deformed mostly by dislocation creep; it shows kink bands and undulose extinction and its fabric is dominated by [001](100). Clinopyroxene displays subgrain rotation, dynamic recrystallization and fabric with [010] axes clustering next to the foliation pole and [001] axes clustering next to the lineation suggesting activation of [001]{110} and [001](100) in some samples. These observations are in good agreement with deformation at temperatures greater than 1000 °C. Olivine in type-1 and type-4 pyroxenites shows [100](010) or [001](010) fabrics that are consistent with deformation at temperatures >1000 °C and may indicate deformation in a hydrous environment. The amphibole [001](100) fabric gives insights on a lower-temperature deformation episode (∼800 to 500 °C). Our results, interpreted in the light of published experimental data, together with the regional geological and geochemical studies are consistent with the following tectonic evolution of the Cabo Ortegal

    Full Text Available In subtropical climate areas, the models and methods proposed to evaluate the chilling requirement of temperate fruit crops often do not provide satisfactory results, thus calling for the development of alternative techniques. The aim of this study was to evaluate the correlations between some phonological traits and chilling requirement for seed germination of 18 peach cultivars and one nectarine cultivar. Two experiments were installed separately for the correlation studies. In experiment 1, the phenological traits were observed in the field, while in experiment 2, the chilling requirement for 50 and 100% seed germination of each cultivar was assessed. The number of days for beginning of bloom (r = 0.70**, 0.61** and full bloom (r = 0.72**, 0.76** were both significantly correlated with the number of chilling units for 50% and 100% germination of seeds. The number of days for beginning of budding and dormancy break were both significantly correlated with the number of chilling units for 50% and 100% germination (r = 0.48*, 0.50*, respectively. However, the same significant effect for these phenological traits was not found between chilling units and 50% germination of seeds, as well as between chilling units and harvest dates.Em regiões de clima subtropical, os modelos e métodos propostos para avaliação da necessidade de frio das fruteiras de clima temperado não apresentam, muitas vezes, resultados satisfatórios.

    Advanced reservoir characterization techniques are being applied to selected reservoirs in the Frio Fluvial-Deltaic Sandstone (Vicksburg Fault Zone) trend of South Texas in order to maximize the economic producibility of resources in this mature oil play. This project is developing interwell-scale geological facies models and assessing engineering attributes of Frio fluvial-deltaic reservoirs in selected fields in order to characterize reservoir architecture, flow-unit boundaries, and the controls that these factors exert on the location and volume of unrecovered mobile and residual oil. The goals of the Industrial Associates program that is the source of industry cofunding to this project are to (1) develop an understanding of sandstone architecture and permeability structure in a spectrum of fluvial-deltaic reservoirs deposited in high- to low-accommodation settings and (2) translate this understanding into more realistic, geologically constrained reservoir models to maximize recovery of hydrocarbons. Project work during the first quarter of 1996 consisted of Phase 3 tasks related to the transfer of technologies to industry. The two primary vehicles for transferring technologies evaluated in the Frio Fluvial-Deltaic Sandstone play (Vicksburg Fault Zone) are a series of two short courses and a microcomputer-based geologic advisor software program. In Rincon field, a three-dimensional (3-D) reservoir model is being constructed to more accurately calculate remaining volumes, and work during the first quarter focused on a sensitivity analysis of varying model parameters.

    Sedimentary basins in general, and deep saline aquifers in particular, are being investigated as possible repositories for large volumes of anthropogenic CO2 that must be sequestered to mitigate global warming and related climate changes. To investigate the potential for the long-term storage of CO2 in such aquifers, 1600 t of CO2 were injected at 1500 m depth into a 24-m-thick "C" sandstone unit of the Frio Formation, a regional aquifer in the US Gulf Coast. Fluid samples obtained before CO2 injection from the injection well and an observation well 30 m updip showed a Na–Ca–Cl type brine with ∼93,000 mg/L TDS at saturation with CH4 at reservoir conditions; gas analyses showed that CH4 comprised ∼95% of dissolved gas, but CO2 was low at 0.3%. Following CO2 breakthrough, 51 h after injection, samples showed sharp drops in pH (6.5–5.7), pronounced increases in alkalinity (100–3000 mg/L as HCO3) and in Fe (30–1100 mg/L), a slug of very high DOC values, and significant shifts in the isotopic compositions of H2O, DIC, and CH4. These data, coupled with geochemical modeling, indicate corrosion of pipe and well casing as well as rapid dissolution of minerals, especially calcite and iron oxyhydroxides, both caused by lowered pH (initially ∼3.0 at subsurface conditions) of the brine in contact with supercritical CO2.These geochemical parameters, together with perfluorocarbon tracer gases (PFTs), were used to monitor migration of the injected CO2 into the overlying Frio “B”, composed of a 4-m-thick sandstone and separated from the “C” by ∼15 m of shale and siltstone beds. Results obtained from the Frio “B” 6 months after injection gave chemical and isotopic markers that show significant CO2 (2.9% compared with 0.3% CO2 in dissolved gas) migration into the “B” sandstone. Results of samples collected 15 months after injection, however, are ambiguous, and can be interpreted to show no additional injected CO2 in the “B” sandstone

    Pyroxenites exposed in ophiolites and orogenic peridotite massifs may record petrogenetic processes occurring in mantle domains generated and/or transferred in supra-subduction environments. However, the timing of their formation and the geochemical characteristics of their source region commonly are obscured by metamorphic and metasomatic overprints. This is especially critical in arc-related environments, where pyroxenites may be formed during the differentiation of primitive magmas. Our approach combines Sr- and Nd-isotope geochemistry and geochronology, and modelling of REE diffusion, to further constrain the origin of a well-characterized set of pyroxenites from the arc-related Cabo Ortegal Complex, Spain. In the light of petrological constraints, Sr- and Nd-isotope systematics consistently indicate that cpx and amphibole have acquired disequilibrium during two main episodes: (1) a magmatic/metasomatic episode that led to the formation of the pyroxenites, coeval with that of Cabo Ortegal granulites and corresponding to the incipient stage of a potential Cadomian arc (459-762 Ma; isochron and second-stage Nd model ages); (2) an episode of metamorphic amphibolitization upon the percolation of relatively unradiogenic and LREE-enriched hydrous fluids, subsequent to the delamination of the pyroxenites from their arc-root settings during Devonian subduction. Calculations of diffusional timescale for the re-equilibration of REE are consistent with this scenario but provide only poor additional constraints due to the sensitivity of this method to grain size and sub-solidus temperature. We thus emphasize the necessity to combine isochron ages and Nd model ages corrected for radiogenic ingrowth to put time constraints on the formation of subduction- and/or collision-related pyroxenites, along with petrological and geochemical constraints. Homogeneous age-corrected 143Nd/144Nd of 0.5121-0.5125 (εNd between 0 and +7.5) and 87Sr/86Sr of 0.7037-0.7048 provide information

Because of that, the determination of the muscle contraction extent represents an important analytical tool for the optimization of the industrial procedures. In this work, two methodologies to evaluate cold shortening were compared. Biceps femoris, Longissimus dorsi and Semimembranosus muscles from 9 cattle carcasses with three different fat thickness grades were paired analyzed by both methodologies. Longissimus dorsi muscle showed the shortest sarcomere length while Semimembranosus m. showed the longest one (p0.05, which suggests the possibility of using the simpler method for cold shortening evaluation.

Sem a ocorrência de baixas temperaturas no outono e inverno, as gemas da macieira continuam em dormência por um maior período. Para mensurar a quantidade de frio necessária para superar a dormência, o método utilizado foi o número de unidades de frio baseado no Modelo Carolina do Norte Modificado. Estacas de 20 a 25 cm de comprimento e estacas de nós isolados receberam zero, 530, 1060 e 1590 unidades de frio durante a dormência. As cultivares testadas foram 'Condessa', 'Baronesa', 'Daiane', 'Imperatriz', 'Gala' e 'Fuji'. As cultivares se diferenciaram quanto ao número de dias para a brotação das gemas, ocorrendo o menor tempo para a brotação quando receberam 1590 unidades de frio, para todas as cultivares, mostrando que há uma relação entre o tempo médio da brotação e a profundidade da dormência. A porcentagem de brotação das gemas foi maior quando as estacas foram submetidas a 1590 unidades de frio, sendo que a cultivar Condessa apresentou o maior percentual de brotação, confirmando as referências que indicam ser esta a cultivar de menor exigência em frio, dentre as estudadas.Apple tree demands periods of low temperatures (4ºC to 10ºC during autumn and winter, otherwise the tree will keep under dormancy or will present an irregular shooting and blooming.

    Los Frailes submarine canyon is located at the south boundary of the Cabo Pulmo National Marine Park on the southeast tip of the Baja California Peninsula. During the Monterey Bay Aquarium Research Institute (MBARI) 2015 Gulf of California expedition we used an autonomous underwater vehicle (AUV) to map this canyon from 50 m to 450 m depths, and then explored the canyon with a small remotely operated vehicle (ROV). This three day R/V Rachel Carson cruise was a collaboration with the Center for Marine Biodiversity and Conservation at Scripps Institution of Oceanography and the Centro para la Biodiversidad Marina y la Conservación in La Paz. The MBARI AUV D. Allan B. collected high resolution bathymetry, sidescan, and subbottom profiles of Los Frailes submarine canyon and part of the north Cabo Pulmo deep reef. In order to safely generate a 1-m lateral resolution multibeam bathymetry map in the nearshore high relief terrain, the mapping operations consisted of an initial short survey following the 100-m isobath followed by a series of short, incremental AUV missions located on the deep edge of the new AUV bathymetry. The MBARI Mini-ROV was used to explore the submarine canyon within the detailed map created by the MBARI AUV. The Mini-ROV is a 1.2-m-long, 350 kg, 1,500-m-depth-rated ROV designed and constructed by MBARI. It is controlled by six 600-watt thrusters and is equipped with a high-definition video camera and navigation sensors. This small ROV carries less accurate, lower cost navigation sensors than larger vehicles. We implemented new algorithms to localize combining Doppler velocity log sensor data and low-cost MEMS-based inertial sensor data with sporadic ultra-short baseline position measurements to provide a high accuracy position estimation. The navigation performance allowed us to colocate the ROV video imagery with the 1-m resolution bathymetric map of the submarine canyon. Upper Los Frailes Canyon is rugged and, aside from small sand pockets along

    Advanced reservoir characterization techniques are being applied to selected reservoirs in the Frio Fluvial-Deltaic Sandstone (Vicksburg Fault Zone) trend of South Texas in order to maximize the economic producibility of resources in this mature oil play. More than half of the reservoirs in this depositionally complex play have already been abandoned, and large volumes of oil may remain unproduced unless advanced characterization techniques are applied to define untapped, incompletely drained, and new pool reservoirs as suitable targets for near-term recovery methods. This project is developing interwell-scale geological facies models and assessing engineering attributes of Frio fluvial-deltaic reservoirs in selected fields in order to characterize reservoir architecture, flow unit boundaries, and the controls that these characteristics exert on the location and volume of unrecovered mobile and residual oil. The results of these studies will lead directly to the identification of specific opportunities to exploit these heterogeneous reservoirs for incremental recovery by recompletion and strategic infill drilling. Project work during the second quarter of 1995 consisted of (1) documentation of Phase II tasks associated with the delineation of untapped and incompletely drained reservoir compartments and new pool reservoirs in selected Frio fluvial-deltaic sandstone intervals in Rincon and Tijerina-Canales-Blucher (T-C-B) fields, as well as (2) tasks related to the transfer of the technologies to industry that aided in delineation. Text and figures have been prepared to support the geological-based compartment architecture and petrophysical analysis is being undertaken to provide a volumetric assessment of remaining resources and recoverable reserves. Petrophysical work during this period has focused on Rincon field reservoirs because of the availability of core material for special core analysis.

    To investigate the potential for the geologic storage of CO2 in saline sedimentary aquifers, 1600 t of CO2 were injected at 1500 m depth into a 24-m-thick sandstone section of the Frio Formation, a regional brine and oil reservoir in the U.S. Gulf Coast. Fluid samples obtained from the injection and observation wells before CO2 injection showed a Na-Ca-Cl–type brine with 93,000 mg/L total dissolved solids (TDS) at near saturation with CH4 at reservoir conditions. Following CO2 breakthrough, samples showed sharp drops in pH (6.5–5.7), pronounced increases in alkalinity (100–3000 mg/L as HCO3) and Fe (30–1100 mg/L), and significant shifts in the isotopic compositions of H2O, dissolved inorganic carbon (DIC), and CH4. Geochemical modeling indicates that brine pH would have dropped lower but for the buffering by dissolution of carbonate and iron oxyhydroxides. This rapid dissolution of carbonate and other minerals could ultimately create pathways in the rock seals or well cements for CO2 and brine leakage. Dissolution of minerals, especially iron oxyhydroxides, could mobilize toxic trace metals and, where residual oil or suitable organics are present, the injected CO2 could also mobilize toxic organic compounds. Environmental impacts could be major if large brine volumes with mobilized toxic metals and organics migrated into potable groundwater. The δ18O values for brine and CO2 samples indicate that supercritical CO2 comprises ∼50% of pore-fluid volume ∼6 mo after the end of injection. Postinjection sampling, coupled with geochemical modeling, indicates that the brine gradually will return to its preinjection composition.

    Full Text Available New coastal development may offer economic benefits to resort builders and even local communities, but these projects can also impact local ecosystems, key wildlife, and the draw for tourists. We explore how light from Cabo Cortés, a proposed coastal development in Baja California Sur, Mexico, may alter natural light cues used by sea turtle hatchlings. We adapt a viewshed approach to model exterior light originating from the resort under plausible zoning scenarios. This spatially explicit information allows stakeholders to evaluate the likely impact of alternative development options. Our model suggests that direct light’s ability to reach sea turtle nesting beaches varies greatly by source location and height—with some plausible development scenarios leading to significantly less light pollution than others. Our light pollution maps can enhance decision-making, offering clear guidance on where to avoid elevated lamps or when to recommend lighting restrictions. Communities can use this information to participate in development planning to mitigate ecological, aesthetic and economic impacts from artificial lighting. Though tested in Mexico, our approach and free, open-source software can be applied in other places around the world to better understand and manage the threats of light pollution to sea turtles.

    The queen conch Eustrombus gigas is an important fisheries resource in the Caribbean region. In Cuba Island the studies about this resource are very scarce and particularly in the Southeastern regions of the country. With the aim to get important fishery information about this gastropod, adult Queen Conch density and frequency of reproductive activity were evaluated in Cabo Cruz, Cuba, during 2009-2010. Data from three seasons were obtained (rainy, dry and cold fronts periods) from three different areas: Farito, Guafe and Laguna. The highest density was observed in cold fronts season (468.5 ind./ha) and the lowest occurred during the dry season (268.5 ind./ha). The highest density was reported at Laguna (520.4 ind./ha) and the lowest at Farito (290.9ind./ha). In total, 158 reproductive events were observed. The highest frequency was reported in rainy season (36%), followed by dry (9%) and cold fronts (5%) seasons. Reproductive behavior (mating and egg laying) was related to temperature and photoperiod. Reproductive activity was observed during the whole year, which suggests the existence of an important Queen Conch reserve in the Southeastern region of Cuba and an apparently self-sufficient population for recruitment. From our results we may conclude that, the population's sustainable exploitation is viable if the following management measures are observed: functional zoning within the area, rotation of fishing areas and a closed season. We recommend that the Laguna site should be protected as a reproduction zone and banned for fishing activities.

    The groundwater of the Cabo de Gata detritic aquifer, in southeastern Spain, exhibit salinities of between 70-726 mmol/L of Cl- (brackish-salt to hypersaline waters). We have investigated the causes of the high salinity anomaly, which at certain points exceeds that of present-day seawater (600 mmol/L). Two hypotheses are considered as possible sources for the saline water: (1) The deeper, more saline groundwater date back to an old marine intrusion that occurred at the end of the last Ice Age (14-17 ka), when seawater salinity was higher than in the present day. This hypothesis is supported by the values of 14C measured in this water (∼6-10 pmc), which indicate old water of up to 17 ka. However, the values of 18O and 2H are lower than would be expected. (2) The water is the result of mixing between fresh groundwater and seawater. The latter explanation agrees well with the low values of 18O and 2H. This mixture is later subject to evaporation, explaining its high salinity. Hydrogeochemical modelling was carried out for the most saline samples, assuming such mixing between freshwater and seawater followed by evaporation, and the results show a very good agreement between the measured and simulated values. According to the model calculation, the original mixture contained approximately 60% seawater and its volume subsequently was reduced through evaporation by around 30%. This mixing and evaporation could occur during the Flandrian Transgression (6000-8000 y), when this area accommodated a coastal lagoon.

Os resultados mostraram que o PHB promove alterações na taxa de cristalização do PET, como verificado por mudanças nos tempos para se atingir 1, 10, 30, 50 e 99% de cristalinidade relativa. As energias de ativação para o primeiro e segundo estágios da cristalização foram determinadas através das curvas de Arrhenius, sendo praticamente independentes da presença de PHB nas misturas PET/PHB. As temperaturas de fusão de equilíbrio foram determinadas de acordo com o procedimento de Hoffman e Weeks; as misturas PET/PHB apresentaram valores mais elevados deste parâmetro sugerindo que o PHB altera a estrutura cristalina do PET.The present work is concerned with the effect of low concentrations (0.5 e 1.0% of poly(3-hydroxybutirate (PHB on the isothermal cold crystallization of poly(ethylene terephthalate (PET. Energy curves were obtained by differential scanning calorimetry (DSC and the kinetics of the crystallization was analyzed using Avrami's method. Two crystallization stages were observed. Results showed that the presence of PHB affects the crystallization rate of PET, as verified by changes in the time needed to reach 1, 10, 30, 50 and 99% of crystallinity. Activation energies for the two crystallization stages were computed using Arrhenius plots; PET/PHB mixtures showed slightly smaller values. The equilibrium melting temperatures were estimated according to the procedure of Hoffman and Weeks; the higher values obtained for the PET/PHB mixtures suggest that PHB affects the crystalline structure of PET.

    Full Text Available Zaratite, Ni3CO3(OH4.4H2O is one of the few minerals discovered in Spain. Taking into account that it is an amorphous compound with variable chemical composition depending on the ore deposits, the International Mineralogical Association (IMA currently considers zaratita in the Q status (Questionable. In this article we analyze first the nearly simultaneous discoveries of the Spanish zaratite and other material called “Emerald of Nickel” from Texas, Lancaster County, Pennsylvania (USA, of similar chemical composition. Both led to the current zaratite, where the Spanish mineral provides the name and the American one, the chemical composition anc physical properties. In addition, here we also include an experimental characterization of the zaratite historical specimen from Ortegal Cape, by electron microprobe, scanning electron microscopy, X-ray diffraction, differential thermal and thermo-gravimetric analyses, micro-Raman, infrared transmission spectroscopy and spectral cathodoluminescence together with a discussion of the analytical results.La zaratita, Ni3CO3(OH4.4H2O es uno de los pocos minerales descubiertos en España.

    Full Text Available The Brazilian coastal zone presents a large extension and a variety of environments. Nevertheless, little is known about biological diversity and ecosystem dynamics. Environmental changes always occur; however, it is important to distinguish natural from anthropic variability. Under these scenarios, the aim of this work is to present a Data Mining methodology able to access the quality and health levels of the environmental conditions through the biological integrity concept. A ten-year time series of physical, chemical and biological parameters from an influenced upwelling area of Arraial do Cabo-RJ were used to generate a classification model based on association rules. The model recognizes seven different classes of water based on biological diversity and a new trophic index (PLIX. Artificial neural networks were evolved and optimized by genetic algorithms to forecast these indices, enabling environmental diagnostic to be made taking into account control mechanisms of topology, stability and complex behavioral properties of food web.A zona costeira brasileira apresenta grande extensão e variedade de ambientes.

    Full Text Available The Cabo Pulmo reef is the most important coral formation of the Gulf of California; however, its ichthyological fauna has not been poorly studied. To produce a systematic list with data on relative abundance and frequency, and biogeographical affinities, we relied on visual census, field observations, analysis of commercial and sport fisheries (from 1986 to 1998, and the literature. A total of 236 species have been recorded at Cabo Pulmo (155 genera and 60 families. This number doubles previous compilations and represents 65.1% of all reef fishes known from the Gulf of California, and about 35% of its entire shallow-water fishes. Of the total species number, 68.3% are from the Panamic Province, 11.0% Indo Pacific colonizers and the same percentage gulf endemics, 7.6% are circumtropical, 1.7% Atlantic and 0.5% cosmopolitan; none are endemic to the reef. The most abundant taxa are the labrids Thalassoma lucasanum, T. grammaticum and the pomacentrid Chromis atrilobata. Only eleven species (4.7% of total appeared in 75% to 100% of census, and 36 (15.3% of total had high levels of both abundance and frequency, evidencing that the community is dominated by few taxa. Local species richness exceeds the number reported for most rocky or coral reefs of the Pacific coast of México, and indicates that Cabo Pulmo is a key area in the gulf and the entire Mexican Pacific, from the ichthyological point of view.

    The junctions of the Amazon and the Rio Negro Rivers at Manaus, Brazil. The Rio Negro flows 2300 km from Columbia, and is the dark current forming the north side of the river. It gets its color from the high tannin content in the water. The Amazon is sediment laden, appearing brown in this simulated natural color image. Manaus is the capital of Amazonas state, and has a population in excess of one million. The ASTER image covers an area of 60 x 45 km. This image was acquired on July 16, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface

    Full Text Available O pessegueiro e a nectarineira são culturas com grande potencial climático e de mercado, mas ainda pouco exploradas no Estado do Paraná. O objetivo deste trabalho foi indicar zonas de menor risco climático para produção dessas culturas no Estado do Paraná, utilizando informações climáticas e agronômicas. Para tanto, foram usados dados históricos de 32 estações meteorológicas do IAPAR, para estimar e mapear os riscos de geadas tardias e o total médio de horas de frio (hf abaixo de 7,2ºC no período maio-setembro. As regiões em que a última geada ocorre antes da fase de floração e com número de horas de frio adequado às exigências das variedades, foram consideradas aptas. Grande parte do norte, oeste e litoral do Paraná não apresenta horas de frio suficientes para as espécies. As áreas localizadas ao sul, com altitudes acima de 800 m, são as mais adequadas. Dentro da área apta, foram classificadas oito zonas, de acordo com a necessidade de frio das variedades de pessegueiro e nectarineira, e a característica de cada região: zona 1 (75 a 150 hf; zona 2 (150 a 200 hf; zona 3 (200 a 250 hf; zona 4 (250 a 300 hf; zona 5 (300 a 350 hf; zona 6 (350 a 400 hf, zona 7 (400 a 450 hf e zona 8 (> 450 hf. As zonas de menor altitude acumulam menos horas de frio e são recomendadas para variedades com menor necessidade de frio. As zonas de maior altitude, que se apresentam com temperaturas mais baixas, têm maior somatório de horas de frio e são recomendadas para variedades com maior necessidade de frio (> 400 horas de frio. A última geada severa provável ocorre no final de agosto, nas regiões mais frias, e não prejudica a floração do pessegueiro e nectarineira. Os resultados obtidos neste estudo possibilitam a adoção de políticas de incentivo a essas culturas com baixo nível de risco, no Estado do Paraná.Peach and nectarine crops, despite their high climatic and market potential, are not yet well exploited in the

O objetivo deste estudo foi verificar o efeito da TENS convencional e na modalidade TENS-acupuntura na dor induzida pelo frio. Trinta indivíduos saudáveis com idade entre 18 e 40 anos foram distribuídos ao acaso em três grupos: placebo, TENS convencional e TENS-acupuntura. Foi utilizado um protocolo de indução de dor pelo frio composto por seis ciclos: dois pré-tratamento, dois durante e dois após o tratamento. A TENS foi aplicada por 20 minutos por dois canais, sendo a modalidade convencional, no nível sensorial, na freqüência de 80 Hz e a modalidade acupuntura, no nível motor, a 4 Hz. Foram medidos limiar de dor, tolerância à dor e intensidade da dor. Não foi encontrada diferença estatisticamente significante nos valores medidos durante a após o tratamento quando comparados aos dos ciclos pré-tratamento, em todas as variáveis. Nas duas modalidades estudadas pois, a TENS, nos parâmetros de aplicação utilizados, não modificou a dor induzida por frio, sugerindo-se novos estudos com maior tempo de aplicação da TENS e diferentes modelos de dor experimental.Transcutaneous electrical nerve stimulation (TENS is a non-pharmacological method already established in the modulation of acute and chronic pain.

As blendas PET/PS formam misturas bifásicas, como confirmado por MEV e por DMA, onde fases distintas e duas Tg s foram observadas. Por outro lado, a determinação da temperatura de fusão de equilíbrio (Tmº do PET por DSC indicou uma diminuição neste parâmetro com a presença do PS, sugerindo que uma solubilidade limitada do PS no PET deve ocorrer. A presença de um componente não cristalizável como o PS, parcialmente solúvel em uma fase cristalizável como PET, reduz a habilidade de cristalização. Isto foi observado nas análises de DSC através do deslocamento dos picos de cristalização a frio do PET para temperaturas maiores e por uma redução na velocidade de cristalização a frio. A abordagem de Avrami foi utilizada para os estudos cinéticos em condições isotérmicas, mostrando que o processo de cristalização ocorre em dois estágios e que a constante de cristalização K diminuiu significativamente com a presença de poliestireno. Nas blendas PET/PS a presença de apenas 1% de PS retardou significantemente a cristalização do PET, em magnitude semelhante ao que ocorreu quando concentrações mais elevadas de PS foram utilizadas. Este comportamento é de grande importância industrial já que em baixa concentração de PS as propriedades mecânicas do PET não são afetadas, como também mostrado neste estudo.The cold crystallization of PET and its blends with polystyrene (PS was investigated by differential scanning calorimetry (DSC, dynamic mechanical thermal analysis (DMA, scanning electron microscopy (SEM and mechanical properties.

    Full Text Available OBJECTIVE: To assess fluoxetine effects on mitochondrial structure of the right ventricle in rats exposed to cold stress. METHODS: The experimental study procedures were performed in 250-300g male EPM-Wistar rats. Rats (n=40 were divided into four groups: 1 Control group (CON; 2 Fluoxetine (FLU; 3 Induced hypothermia (IH and; 4 Induced hypothermia treated with fluoxetine (IHF. Animals of FLU group were treated by the administration of gavages containing 0.75 mg/kg/day fluoxetine during 40 days. The induced hypothermia was obtained by maintaining the groups 3 and 4 in a freezer at -8ºC for 4 hours. The animals were sacrificed and fragments of the right ventricle (RV were removed and processed prior to performing electron microscopic analysis. RESULTS: The ultrastructural changes in cardiomyocytes were quantified through the number of mitochondrial cristae pattern (cristolysis. The CON (3.85%, FLU (4.47% and IHF (8.4% groups showed a normal cellular structure aspect with preserved cardiomyocytes cytoarchitecture and continuous sarcoplasmic membrane integrity. On the other hand, the IH (34.4% group showed mitochondrial edema and lysis in cristae. CONCLUSION: The ultrastructural analysis revealed that fluoxetine strongly prevents mitochondrial cristolysis in rat heart, suggesting a protector effect under cold stress condition.OBJETIVO: Analisar os efeitos da fluoxetina sobre a estrutura mitocondrial do ventrículo direito de ratos expostos ao estresse pelo frio.

    Brazil, the largest country in South America with a population of almost 140 million, has been plagued since the early 1980s by high foreign debt (approximately US$121 billion at present) and hyperinflation (nearly 600 percent over the past 12 months). These factors, in combination with the slower than anticipated growth in electricity demand, have been instrumental in curtailing nuclear power development in the country. Following recommendations advanced in a commissioned study for improving Brazil`s nuclear program, Brazilian President Jose Sarney announced on August 31st the restructuring of the country`s nuclear industry.

    Full Text Available Cold agglutinin disease (CAD with autoimmune haemolytic anemia is characterized by the production of harmful cold autoantibodies associated with increased red cell destruction during exposure to cold. The treatment of CAD is very difficult and a great effort is required to obtain therapeutic success. Cyclophosphamide is a potent immunosuppressive agent which is widely used in all bone marrow transplantation conditioning regimens for patients with acquired severe aplastic anemia. In this report, we describe the case of a coronary artery disease patient with severe CAD, but without lymphoproliferative disease, in which general measures and immunosuppressive therapies were adopted, there by avoiding blood transfusions.A doença por aglutininas a frio (CAD cursando com anemia hemolítica auto-imune (AHAI é decorrente da produção de autoanticorpos que reagem muito bem a baixas temperaturas, dirigidos contra hemácias autólogas. A habilidade desses anticorpos em destruir as hemácias encontra-se diretamente relacionada à sua capacidade em fixar complemento durante a exposição do paciente a baixas temperaturas. A AHAI por anticorpos frios pode ser idiopática - ausência de doença de base - ou secundária, geralmente associada a desordens linfoproliferativas de células B ou determinados processos infecciosos. A hemólise é intravascular, através de aglutininas da classe IgM, com teste direto da antiglobulina humana positivo para complemento. O tratamento da CAD é difícil, exigindo um esforço contínuo, necessário para se obter sucesso terapêutico. A ciclofosfamida é um agente imunossupressor potente, amplamente utilizado em transplantes de medula óssea, particularmente nos portadores de anemia aplástica. Descrevemos o caso de um coronariopata portador de CAD severa, cuja exploração diagnóstica excluiu doença linfoproliferativa. Adotamos medidas gerais de suporte e terapia imunossupressora, coibindo o uso de hemotransfusões.

    Full Text Available RESUMO: A Análise de elementos estruturais, realizadas durante as etapas de projeto de uma estrutura, é parte fundamental para garantia de bom desempenho e estabilidade do sistema estrutural. Na execução de algumas estruturas, como as coberturas em edificações, é usual o emprego de perfis leves de aço formados a frio devido ao seu baixo peso. Esta pesquisa tem por objetivo avaliar a eficiência estrutural desses perfis quando comparados, por exemplo, aos perfis soldados compactos. Para tanto, foram realizados ensaios de flexão em quatro vigas biapoiadas submetidas a duas forças concentradas, de forma a se obter flexão pura no meio do vão das vigas. Estas foram instrumentadas para a determinação da sua rigidez e da sua resistência à flexão. A principal contribuição deste trabalho é demonstrar a eficiência estrutural de perfis formados a frio em seção caixa submetidos à flexão em comparação com perfis de seção tipo “H” soldados. ABSTRACT: The analysis of structural elements, in a structure’s design, is an essential step to ensure good performance and stability of the structural system. In any types of structures, such as roofing in buildings, it’s usual using cold-formed steel beams due to their small weight. This research seeks to evaluate the structural efficiency of cold-formed steel beams when compared, for example, to compact welded steel beams. Thus, bending tests were performed in four simply supported beams submitted to two concentrated loads, in order to obtain pure flexure at the mid-span of the beams. These beams were instrumented for the determination of their rigidity and bending strength. The results showed that the cold-formed steel beam, box-shaped, presented structural efficiency similar to the welded steel beam “H” shaped.

    Full Text Available The formation of Los Frailes volcano had two stages, which produced amphibole andesites (Frailes-I and two-pyroxene andesites (Frailes-II respectively, Iying on the extension of the dacites and andesites of the southernmost Cabo de Gata volcanoes (Revancha-Sabinal. The FRAILES-I stage is discontinuous, and has mainly produced domes and autoclastic breccias, in addition to an intermediate level of pumice-and-ash flow; this unit has some intercalated sedimentary levels. To the NE it is covered by a formation of sedimentary and hydroclastic rocks. The Frailes-II stage is continuous, and has formed some lava flows, the two summit domes, and sorne pyroclastic rocks of scarcely explosive origin. Other volcanic features are some domes and dikes of biotite-amphibole dacites, which affect to the Frailes-I-group; these are the southern continuation of the dacitic volcanic group of Rodalquilar-Rellana-Garbanzal. The generally accepted idea of a succesion in Cabo de Gata of cycles which started very explosively and ended with subvolcanic extrussions (domes does not seem to be very realistic at least in the building of Los Frailes. A review of geochronological data, and the field disposition of the described materials does not discard the hypothesis that the pyroxene andesites of FrailesI-I might have been formed simultaneously or even than later the ignimbritic dacites of the Rodalquilar group.La formación del volcán de Los Frailes se produjo en dos ciclos, de composiciones andesítica anfibólica (Frailes-I y andesitica de dos piroxenos (Frailes-II, apoyadas sobre la prolongación hacia el este de las andesitas y dacitas del extremo sur de Cabo de Gata (edificio de Revancha-Sabinal-Cabo de Gata.

    Beryllium-7 ( 7 Be) is a natural radionuclide of cosmogenic origin, normally used as a tracer for several environmental processes; such as soil redistribution, sediment source discrimination, atmospheric mass transport, and trace metal scavenging from the atmosphere. In this research the content of 7 Be in soil, its seasonal variation throughout the year and its relationship with the rainfall regime in the Mato Frio creek micro-watershed was investigated, to assess its potential use in estimating soil erosion. The 7 Be content in soil shows a marked variation throughout the year. Minimum 7 Be values were observed in the dry season (from April to September) and were between 7 and 14 times higher in the rainy season (from October to March). The seasonal oscillations in 7 Be soil content could be explained by the asymmetric rainfall regime. A highly linear relationship between rainfall amount and 7 Be deposition was observed in rain water. A good agreement between 7 Be soil content and 7 Be atmospheric deposition was noticed, mainly in wet months. 7 Be penetration in soil reaches a 5 cm depth, this could be explained by the soil type in the region. The soils are Acrisol type, characterized by low pH values and clay illuviation in deeper layers of the soil. In some regions of Brazil special attention should be paid if this radionuclide will be used as soil erosion tracer, taking into account the soil origin and its particular properties.

    Malaria rapid diagnostic tests (RDTs) are particularly useful in low-resource settings where follow-through on traditional laboratory diagnosis is challenging or lacking. The availability of these tests depends on supply chain processes within the distribution system. In Mozambique, stock-outs of malaria RDTs are fairly common at health facilities. A longitudinal cross-sectional study was conducted to evaluate drivers of stock shortages in the Cabo Delgado province. Data were collected from purposively sampled health facilities, using monthly cross-sectional surveys between October 2011 and May 2012. Estimates of lost consumption (consumption not met due to stock-outs) served as the primary quantitative indicator of stock shortages. This is a better measure of the magnitude of stock-outs than binary indicators that only measure frequency of stock-outs at a given facility. Using a case study based methodology, distribution system characteristics were qualitatively analysed to examine causes of stock-outs at the provincial, district and health centre levels. 15 health facilities were surveyed over 120 time points. Stock-out patterns varied by data source; average monthly proportions of 59%, 17% and 17% of health centres reported a stock-out on stock cards, laboratory and pharmacy forms, respectively. Estimates of lost consumption percentage were significantly high; ranging from 0% to 149%; with a weighted average of 78%. Each ten-unit increase in monthly-observed consumption was associated with a nine-unit increase in lost consumption percentage indicating that higher rates of stock-outs occurred at higher levels of observed consumption. Causes of stock-outs included inaccurate tracking of lost consumption, insufficient sophistication in inventory management and replenishment, and poor process compliance by facility workers, all arguably stemming from inadequate attention to the design and implementation of the distribution system.

    Rainfall variability, the occurrence of extreme drought and historic land management practice have been recognised as contributing to serious environmental impact in Cabo Verde. Investment in conservation measures has become visible throughout the landscape. Despite this the biophysical and socioeconomic impacts of the conservation measures have been poorly assessed and documented. As such a concerted approach based on the DESIRE project continues to consult stackholders and carry out field trials for selected conservation technologies. Recent field trials have demonstrated the potential of conservation technologies but have also demonstrated that yield variability between sites and between years is significant. This variability appears to be driven by soil and rainfall characteristics However, where detailed field studies have only run for a limited period they have not as yet encountered the full range of climatic variability; thus a modelling approach is considered to capture a greater range of climatic conditions. The PESERA-DESMICE model is adopted which considers the biophysical and social economic benefits of the conservation technologies against a local baseline condition. PESERA is adopted as climate is implicitly considered in the model and, where appropriate, in-situ conservation measures are considered as an annual input to the soil. The DESMICE component of the model considers the suitability of the conservation measures and their costs and benefits in terms of environmental conditions and market access. Historic rainfall statistics are calculated from field measurements in the Ribeira Seca catchment. These statistics are used to generate a series of 50 year rainfall realisations to capture a fuller range of the climatic conditions. Each realisation provides a unique time-series of rainfall and through modelling can provide a simulated time-series of crop yield. Additional realisations and model simulations add to an envelope of the potential crop

Embora sua etiologia não esteja totalmente definida, sabe-se que sua ocorrência é precedida de esforço físico extenuante, exposição ao frio ou água fria e confinamento em caixas de transporte. O presente trabalho descreve o caso de um cão da raça Labrador Retriever, macho não castrado, de quatro anos de idade que apresentou súbita dor e flacidez da cauda após banho frio. Fratura vertebral, síndrome da cauda eqüina, outras enfermidades da medula espinhal ou de glândulas adanais e afecções prostáticas foram descartadas após exames auxiliares. A divulgação deste relato é relevante uma vez que esta síndrome ainda não foi descrita no Brasil.Limber syndrome is a disease that occurs in hunting dogs, commonly Labrador retriever and in dogs that belong to the group of Pointer. The aetiology is still unknown, but its occurrence is prior to extenuating exercises, cold exposure and cold water and transport jail maintenance. This article describes the case of a 4-year-old-intact-male Labrador Retriever that suddenly developed tail pain and limberness after cold bath. It was possible to exclude vertebral fracture, cauda equina syndrome, spinal cord or adanal gland injuries and prostatic disease as the auxiliary evaluations were made. This publication is important because there are no reports of Limber syndrome in Brazil.

    Full Text Available Visceral leishmaniasis (VL is among the most important vector-borne diseases that occur in Brazil, mainly due to its zoonotic nature. It is currently present in almost all Brazilian territory, and its control is a challenge both for veterinarians and for public health officials. The etiologic agent is Leishmania infantum (syn chagasi, and the main vector in Brazil is Lutzomyia longipalpis. Of all animals identified as reservoirs of VL, the dog is considered the most important domestic reservoir. Although the disease has already been identified in cats, the epidemiological role of this animal species is still unclear. This article presents a brief review of the epidemiological situation of the disease, its mode of transmission, clinical features in dogs and cats as well as possible risk factors associated with the occurrence of the disease in Brazil.

    Many countries in the Americas describe themselves as "nations of immigrants." In the United States, the myth of the "promised land" suggests that foreigners better themselves upon arrival because the nation is intrinsically great. In Brazil, however, the relationship between immigration and national identity is different. Many intellectuals, politicians, and cultural and economic leaders saw (and see) immigrants as improving an imperfect nation that has been tainted by the history of Portuguese colonialism and African slavery. As a result, immigrants were often hailed as saviors because they modified and improved Brazil, not because they were improved by Brazil. This "improvement" took place through absorption, mixture and with the use of increasingly flexible racial and ethnic categories.

    This article focuses on scientific integrity and the identification of predisposing factors to scientific misconduct in Brazil. Brazilian scientific production has increased in the last ten years, but the quality of the articles has decreased. Pressure on researchers and students for increasing scientific production may contribute to scientific misconduct. Cases of misconduct in science have been recently denounced in the country. Brazil has important institutions for controlling ethical and safety aspects of human research, but there is a lack of specific offices to investigate suspected cases of misconduct and policies to deal with scientific dishonesty.

    The striped marlin (Tetrapturus audax) is found in temperate and tropical waters of the Pacific and Indian Ocean. It is particularly abundant in the southern tip of the Baja California peninsula. Specimens brought to Cabo San Lucas port (22 degrees 53' N y 109 degrees 54' W) by the sport fishery fleet that operates withing a radius of 54 km from 1988 to 1993 were sexes, measured and weighed. A total 1030 individuals were sampled. Dorsal fin spines (389) were collected for age estimation. The spines were sectioned and hyaline-opaque bands counted. The relation of length to spine radius was similar for males and females. The fourth dorsal spine reflected the growth of the fish. The rhythm of growth mark formation is yearly and related to the sea surface temperature. Ten age groups were found and the seventh group was the most abundant, followed by groups "6" and "8". The age structure of the striped marlin was stable in the study period. The observed sizes were 160-280 cm jaw length with 90% of the organisms measuring between 190 and 225 cm. The small individuals recruit to the fishery from June to December.

    Full Text Available Severe land degradation has strongly affected both people’s livelihood and the environment in Cape Verde (Cabo Verde in Portuguese, a natural resource poor country. Despite the enormous investment in soil and water conservation measures (SWC or SLM, which are visible throughout the landscape, and the recognition of their benefits, their biophysical and socioeconomic impacts have been poorly assessed and scientifically documented. This paper contributes to filling this gap, by bringing together insights from literature and policy review, field survey and participatory assessment in the Ribeira Seca Watershed through a concerted approach devised by the DESIRE project (the “Desire approach”. Specifically, we analyze government strategies towards building resilience against the harsh conditions, analyze the state of land degradation and its drivers, survey and map the existing SWC measures, and assess their effectiveness against land degradation, on crop yield and people’s livelihood. We infer that the relative success of Cape Verde in tackling desertification and rural poverty owes to an integrated governance strategy that comprises raising awareness, institutional framework development, financial resource allocation, capacity building, and active participation of rural communities. We recommend that specific, scientific-based monitoring and assessment studies be carried out on the biophysical and socioeconomic impact of SLM and that the “Desire approach” be scaled-up to other watersheds in the country.

    2003-01-01

    This is an account of my trips to Brazil in 2001 where I worked on a series of mental health projects with Brazilian colleagues. I first got interested in Brazil after I graduated from college when I was a Peace Corps volunteer in Northeast Brazil (Bahia state). After I got out of the Peace Corps I moved to Rio de Janeiro and went to work for United Press International (UPI) in their Rio bureau. I was UPI foreign news correspondent for a year and a half. Those years in Brazil were probably the happiest years of my life. Later on, after I became ill in the U.S., my Brazilian connection played an important role in my recovery. Raised in a Victorian family in a small town in the Midwest, and schooled in a traditional boarding school for boys and then at an all men's college, Brazil's lively Latino culture served as a healthy antidote for my tendency to be reserved and often depressed. My contact with Brazilians and Brazilian culture always beckoned me on. I maintained contact with my friends in Brazil and they stuck by me through my illness years. What seemed like my emotional and intellectual "excess" to me, was easily accepted by my Brazilian friends. I felt much more myself interacting with Brazilians and connected to a larger sense of self I developed in Brazil. I traveled to Brazil at every opportunity and made friends with Brazilians I met in the States. I initiated Portuguese classes at John Carroll University in Cleveland, Ohio in the early 1990s and then was invited to teach Brazilian culture to undergraduates. These appointments and my own resilience moved me past one depression and a dysthymia condition and into the wider community. I regained my confidence as a teacher, a role I had before and during the years of my illness. From this position, I organized a club for Brazilian students studying in the Cleveland area. After this teaching stint, I felt ready to pursue full time employment and began a job search that would eventually land me in New Haven at

    Full Text Available Carcaças bovinas resfriadas rapidamente podem apresentar uma contração muscular conhecida como encurtamento pelo frio. Esse fenômeno, prejudicial à textura da carne, ocorre principalmente nas fibras musculares oxidativas. O objetivo deste trabalho foi disponibilizar uma ferramenta analítica para distinguir essas fibras e determinar com maior precisão a contração do tecido muscular pela mensuração do comprimento dos sarcômeros. Amostras do músculo Longissimus dorsi de 12 novilhas nelore foram coletadas. As amostras obtidas de uma das meias-carcaças foram submetidas a uma refrigeração rápida, e as amostras provenientes da outra meia-carcaça à refrigeração lenta. Foi testado um método analítico, baseado na técnica de coloração por Nicotinamida Adenina Dinucleotídeo - Tetrazolium Redutase (NADH-TR, para mensurar, por microscopia, o comprimento dos sarcômeros das fibras vermelhas. Foram determinadas as velocidades de queda de pH e temperatura, a área do olho de lombo (AOL e a força de cisalhamento. Os resultados demonstraram que a temperatura é o principal fator responsável pelo comprimento do sarcômero quando a velocidade de resfriamento é rápida, sendo essa influência menor quando a queda de temperatura é mais lenta. Desta forma, demonstrou-se que a técnica de coloração com NADH-TR é capaz de detectar a ocorrência do encurtamento pelo frio nos músculos esqueléticos de bovinos.Bovine carcasses quickly cooled may develop a muscle contraction known as cold shortening. This process, harmful to meat texture, occurs mainly in the oxidative muscle fibers.

    Brazil is one of the world's largest economies and the country also has significant heavy oil reserves. This report from the National Petroleum Agency of Brazil aims at presenting the situation of the oil and gas sector in Brazil in terms of resources, production, regulatory framework and opportunities for the future. Brazil has numerous sedimentary basins at its disposal, most of them being prospected by both national and foreign companies from all over the world. Brazil has over 14 billion barrels of proven reserves, its production is 2,1 MMBbl/d and heavy oil represents almost 40% of that production. The National Petroleum Agency of Brazil is responsible for the implementation of oil sector policy with the aims of maintaining self-sufficiency, implementing good practices in terms of health and safety, and increasing local content. This paper pointed out that Brazil has an important opportunity to enhance its energy sector through the development of heavy oil.

    The diabetes epidemic affects most countries across the world and is increasing at alarming rates in Latin America. Nearly 12 million individuals have diabetes in Brazil, and the current prevalence ranges from 6.3% to 13.5%, depending on the region and the diagnostic criteria adopted in each study. To provide an overview of diabetes care in Brazil, focusing on studies of diabetes epidemiology, prevalence of patients within the standard targets of care, and economic burden of diabetes and its complications. SciELO and PubMed searches were performed for the terms "diabetes," "Brazil," "Brazilian," and "health system"; relevant literature from 1990 to 2015 was selected. Additional articles identified from reference list searches were also included. All articles selected were published in Portuguese and/or English. Recent studies detected a prevalence of gestational diabetes mellitus of nearly 20%. Among patients with type 1 diabetes, almost 90% fail to reach target of glycemic control, with less than 30% receiving treatment for both hypertension and dyslipidemia. More than 75% of patients with type 2 diabetes are either overweight or obese. Most of these patients fail to reach glycemic targets (42.1%) and less than 30% reached the target for systolic and diastolic blood pressure, body mass index, or low-density lipoprotein cholesterol. Only 0.2% of patients reach all these anthropometric and metabolic targets. Brazil is the fourth country in the world in number of patients with diabetes. Regardless of the diabetes type, the majority of patients do not meet other metabolic control goals. The economic burden of diabetes and its complications in Brazil is extremely high, and more effective approaches for preventions and management are urgently needed. Copyright © 2015.

    ógicos demonstrando essa associação, poucas pesquisas têm sido realizadas para investigar os sistemas de representação nacional de esquizofrenia nesses países. OBJETIVOS: Este estudo está focado nos fatores culturais da esquizofrenia, a saber: os sistemas de representação nacional da enfermidade, bem como o que se entende no país como comportamento desviante e sua aceitação e os mecanismos de inserção ou exclusão sociocultural dos pacientes com esquizofrenia em Cabo Verde, África. MÉTODOS: Foram realizadas entrevistas abertas aleatorizadas com parentes de pacientes em tratamento no serviço ambulatorial de saúde mental do Hospital Batista de Sousa (Ilha de São Vicente, entre 1994 e 1995. As entrevistas avaliaram os históricos da doença dos pacientes em relação aos problemas e estratégias utilizadas pela família para lidar com tais problemas e comentam sobre a sobrecarga social e familiar. RESULTADOS: Vinte entrevistas com parentes próximos de 10 pacientes foram analisadas. O estudo foi focado em três categorias principais para explicar a esquizofrenia: "cabeça cansada", "nervoso" e categorias sobrenaturais (como "bruxaria" e feitiçaria". Os entrevistados expressaram sua opinião, seja de forma explícita ou não, sobre se seus parentes realmente tinham uma doença. CONCLUSÕES: As características das categorias nacionais da esquizofrenia encontradas em Cabo Verde podem ser encaradas como uma forma menos estigmatizante de tratar a doença. É razoável supor que a compreensão desses fatores culturais poderia levar a melhores desfechos no tratamento de esquizofrenia neste país e também em outros onde similares condições podem ser identificadas.

    This work constitutes the first assessment of tributyltin (TBT) pollution levels in the Republic of Cabo Verde (Africa) and proposes the marine gastropod Gemophos viverratus (Kiener, 1834) as a new bioindicator of TBT pollution in the Macaronesia and west coast of Africa. Specimens were collected between August and October 2012 along a gradient of naval traffic in São Vicente Island. The results clearly indicate an increase of imposex levels (percentage of females affected with imposex, 0-100 %; vas deferens sequence index, 0-4.1; relative penis length index, 0-54.6 %) and female TBT contamination (from 5 to 37 ngSn g(-1) dry weight (dw)) from outside to inside the harbour of Porto Grande Bay and identify this area as the focus of TBT pollution in the island. The butyltin degradation index for G. viverratus tissues ranged between 1.3 and 2.2, which being above 1 suggests that a considerable part of TBT inputs to the bay may not be very recent. Sterile females were found inside the harbour with an incidence up to 21.4 %. Considering the existence of a planktonic veliger stage in the life cycle of G. viverratus, it is expected that recruitment of newborn individuals can be supplied from unaffected breeding females inside and outside the Porto Grande Bay, resulting in a reduced impact of TBT pollution on population abundance. G. viverratus is very promising to be used as a simple, inexpensive and efficient novel tool for TBT pollution biomonitoring in the Macaronesia and west coast of Africa, a region for which there is an astonishing lack of information concerning levels and ecological impacts of TBT pollution.

    In the presence of biofilms, stainless steels (SS) exhibits an increase in corrosion potential, called ennoblement. In the present study, the corrosion potential ( E corr) behavior of the duplex SS UNS S32760 was recorded simultaneously with the in situ marine biofilm formation in two areas at Arraial do Cabo, Southeastern Brazil. The biofilm at Forno Harbor (an anthropogenically disturbed area) was characterized by higher relative abundances of Bacteria at day 2, followed by diatoms (especially Navicula sp.) on day 10 and dinoflagellates on day 18, whereas no clear trend was recorded at Cabo Frio Island (an undisturbed area). The ennoblement of E corr values was site-dependent. In a complementary laboratory assay, biofilms were removed and the E corr values registered in sterile conditions for the subsequent 10 days and corroborated in situ results. Understanding biofilms and SS interactions has important implications for materials science and engineering decisions as well as helping to fill in important gaps in this knowledge.

    Full Text Available In 1975 the Special Programme for Schistosomiasis Control was introduced in Brazil with the objective of controlling this parasitic disease in six northeastern states. The methodology applied varied largely from state to state, but was based mainly on chemotherapy, This Programme was modified about ten years after it beginning with the main goals including control of morbidity and the blockage of establishment of new foci in non-endemic areas. In two states, Bahia and Minas Gerais, the schistosomiasis control programme started in 1979 and 1983, respectively. The recently made evaluation of those two programmes is the main focus of this paper. It must also be pointed out, that the great majority of the studies performed by different researchers in Brazil, at different endemic areas, consistently found significant decrease on prevalence and incidence, when control measures are repeatedly used for several years. Significant decrease of hepatosplenic forms in the studied areas is well documented in Brazil. After more than 20 years of schistosomiasis control programmes in our country, chemotherapy has shown to be a very important tool for the control of morbidity and to decrease prevalence and incidence in endemic areas. Nevertheless, in medium and long terms, sanitation, water supply, sewage draining and health education seem to be the real tools when the aim is persistent and definitive schistosomiasis control.

    Full Text Available The number of schools of pharmacy has been increasing each year in Brazil. From 2002 to 2013 over 300 new schools were opened in Brazil with a final number of 415 schools of pharmacy in operation around the country. Of these schools, only 28 schools offer a course in radiopharmacy (7.77%. However, the demand for such trained professionals has grown exponentially in Brazil, especially following amendment 49 (February 2006 that broke the monopoly on the production, distribution, and marketing of short half-life radiopharmaceuticals, and the recent constitutional amendment project 517/2010, which was approved in the last instance and is waiting for final approval by the President. Thus, in this scenario, there are a total of 417 radiopharmacy services across the country waiting for qualified professionals to fill posts. However, while there are insufficient trained professionals, radiopharmacy services under the aegis of Agencia Nacional de Vigilancia Sanitaria - Brazilian Health Surveillance Agency allow biomedical scientists and biologists to perform specialized functions as developed in radiopharmacy services without the presence of radiopharmacists.

    2007-01-01

    Brazil, a Latin American country of continental proportions and contrasts, demographic inequalities, and social inequities, concomitantly faces the challenge of preventing and controlling infectious diseases, injuries, and non-communicable diseases. The loss of strength of the biomedical paradigm, the change in epidemiological profile, and the sociopolitical and cultural challenges of recent decades have fostered the emergence of new formulations about public health thinking and practice. Among them, are the paradigms of Brazilian Collective Health and Health Promotion. The former provides philosophical support for Brazil's Unified Health System (SUS). The aim of this article is to discuss the development of public health within the country's history, and to analyze and compare the theoretical assumptions of Health Promotion and Collective Health. We conclude that health promotion, based on the principles and values disseminated by the international Charters and concerned with social actors and social determinants of the health-disease process, has significant potential to promote the improvement of living and health conditions of the population. This frame of reference guided the formulation of the National Policy of Health Promotion within the Unified Health System, which was institutionalized by a ministerial decree. The importance and application of evaluating the effectiveness of health promotion processes and methodologies in Brazil have been guided by various frames of reference, which we clarify in this article through describing historical processes.

    Full Text Available La mezcla de culturas y la coexistencia de grupos de origen diverso, pertenecientes a diferentes tradiciones, y con una historia propia se ha vuelto una realidad indiscutible de la Europa actual. Realidad en la que surgen nuevas formas culturales marcadas por perfiles híbridos y contornos indefinidos y cambiantes, que para el observador resulta difícil de aprehender. Asimismo porque, más que ante grupos social y culturalmente bien delimitados que pretenden o rechazan su integración socio-cultural, nos encontramos ante todo con una amplia gama de situaciones imprecisas y con constantes transferencias de un continente a otro. Este tipo de fenómenos no son, sin embargo, algo inédito en la historia de sociedades y culturas. Por el contrario, hubo épocas y áreas geográficas en las que, como resultado de procesos de expansión y migración a gran escala, el contacto intercultural fue particularmente intenso y rico. El caso del descubrimiento y posterior conquista y colonización del Nuevo Mundo es, en este sentido, uno de los más relevantes debido a la diversidad de razas y culturas que entraron en contacto; hasta el punto de que los distintos mestizajes o simbiosis que allí se produjeron constituyen una de las características esenciales de la Historia de América. Con el objetivo de poder contribuir a reflexionar sobre esta temática, tratamos de identificar, examinar y aclarar conceptos como aculturación, inculturación, transculturación y mestizaje, los agentes mediadores en el proceso socio-educativo, las modalidades de comunicación, las semejanzas y diferencias entre la labor llevada a cabo en la isla y en Tierra Firme; para ello abordamos y estudiamos la labor socio-educativa de dos personajes que emigraron al Nuevo Mundo, Ramón Pané y Hernán Cortés.

Foram utilizados dados de 13 estações de superfície bem distribuídas pelo Estado, no período de 39 anos, compreendido entre 1967 e 2005. As relações entre ondas e ENOS foram obtidas a partir da análise de tabelas de contingência 2 x 2 para os meses centrais de cada estação do ano. A significância estatística foi avaliada através do teste exato de Fischer. Observou-se que a variabilidade sazonal das ondas de frio é diferente da variabilidade das ondas de calor. Ocorrem mais ondas de frio nos meses com as temperaturas mínimas mais baixas, e as ondas de calor têm comportamento mais heterogêneo. Na maioria das localidades, é em julho que as relações entre a ocorrência de ondas de calor e os eventos El Niño são mais significativas. Para La Niña e ondas de Frio, o mês com relações mais significativas foi abril. Em ambos os casos, nota-se que há defasagem entre a ocorrência dos eventos El Niño/La Niña e o seu impacto no surgimento de ondas de calor/frio.This work investigates the seasonal variability occurrence of cold and warm waves in the Brazilian State of Rio Grande do Sul and its relationships with El Niño and La Niña events. 39 years (1967-2005 temperature data series from 13 uniformly distributed meteorological stations over the State were used. The relationships between waves and ENOS were obtained from 2x2 contingence table analysis for the central months of each season. The statistical significance was evaluated using the Fisher exact test. It was observed that the seasonal variability of cold waves is different than the warm wave variability. There are more cold waves during the months with lowest minimum temperatures, and the warm waves have a more heterogeneous behavior.

    Full Text Available RESUMO: Este trabalho objetivou encontrar o perfil “I” com melhor eficiência para vigas submetidas à flexão. Foram comparados três modelos de perfis metálicos, sendo eles: formado a frio e soldado, tipo viga soldada e laminado. Foram confeccionados quatro corpos de prova de cada modelo, sendo estes todos com comprimento de 1500mm, simulando perfis comumente usados na confecção de vigas de estruturas metálicas. Todos os corpos de prova foram ensaiados em laboratório, utilizando-se um pórtico de cargas para aplicar uma carga pontual no centro do vão. A carga foi aumentada gradativamente, e a cada intervalo tomou-se nota da deformação vertical no centro do perfil. Ao final do ensaio, foram analisados os resultados de resistência de cada modelo de perfil e seus custos comparados. Conclui-se que os perfis confeccionados em aço laminado apresentam a melhor eficiência na resistência à carga e também menor custo por metro de viga, proporcionado uma economia aproximada de 20% em relação aos outros modelos estudados. ABSTRACT: This study aimed to find the profile "I" with better efficiency for beams subjected to bending. Three models of steel profiles were compared, namely: cold-formed and welded, welded beam type and laminate. They were made four specimens of each model, all with length of 1500mm, simulating profiles commonly used in the manufacture of steel beams. All samples were tested in the laboratory, using a frame loads to apply a point load in the center of the span. The load was gradually increased, and the vertical deflection at the center of the profile, recorded every interval. At the end of the test, the strength results of each profile model and their costs were analyzed. We conclude that the laminate steel profiles have highest efficiency considering the applied load and also lower cost per meter of beam, providing an approximate saving of 20% compared to other studied models.

Análise comparativa realçou semelhanças e divergências de práticas de saúde ou em caso de doença. O estudo foi efetuado numa amostra de 40 cabo-verdianos da primeira geração residentes na região de Lisboa, dividida em subgrupos: grupo social, geração e genero. Baseou-se em metodologia qualitativa com entrevistas semi-estruturadas. As práticas analisadas foram agrupadas em preventivas e de saúde, práticas utilizadas em episódios de doença, recursos para prevenção e tratamento, utilização de remédios caseiros e outros recursos ou terapeutas. Indivíduos experimentaram, ao nível das práticas, três sistemas de saúde que coexistiam em Cabo Verde, oficial, popular e tradicional e o recurso à religião. O discurso acerca das práticas de saúde e de doença demonstrou existirem diferenças, em alguns aspectos, entre grupos sociais e entre generos e gerações. Práticas de saúde destes imigrantes são idênticas às dos portugueses em contextos socioeconomicos semelhantes. Resultados sugerem existência de diferenças entre grupos sociais relativamente às práticas, na esfera da saúde e da doença. Mais que cultura e etnicidade, que se moldam às condições materiais de existência, neste estudo, o nível socioeconomico determinou as maiores diferenças a interferir nas práticas de saúde e doença, de grupo com cultura de base comum. Em geral, os indivíduos sobrevalorizaram sua identidade étnica e cultura de origem. Pertencimento a grupos sociais diferentes dá origem a partilha do sentimento de pertença cultural, mas não a comportamentos e práticas idênticos.This study aims at analysing, through personal reports, the way individuals behave in terms of health and illness.

    Full Text Available On the west coast of Tierra del Fuego, south of Cabo Nariz, in Chile, Upper Cretaceous to Paleocene sedimentary successions of the Magallanes foreland basin crop out. The presence of dinoflagellate cysts, as well as radiometric U-Pb SHPJMP dating of detrital zircons, indicate that this succession ranges from the Campanian to Thanetian (Late Paleocene in age. The base of the exposed sedimentary succession comprises siltstones of external platform facies (Cerro Cuchilla Formation, which are thrust over the Cabo Nariz Beds. The latter fonnation is divided into two members: a lower siltstone-dominated turbidite facies member and an upper member of sandstone-dominated turbidites, with sandstone and conglomérate channel facies. The presence of dinocysts in the Cerro Cuchilla Formation suggests a late Campanian to early Danian age. The fossil content in the Cabo Nariz Beds indicate a Selandian (Middle Paleocene depositional age in accordance with the detrital zircon ages which provide a maximum possible Campanian age (76.5±0.7 Ma, and very close to the Thanetian (Late Paleocene (57.6±1 Ma depositional ages for the lower and upper member, respectively. The sedimentary succession of Cabo Nariz Beds, is interpreted as a north-northwest prograding submarine fan of middle to Late Paleocene age. It is considered to represent the deposition of detritus derived from an uplifting orogen located to the south. The detrital zircon age spectra suggest that there was a period of low intensity of magmatic activity in the source area around the K-T boundary.En la costa occidental de Tierra del Fuego, al sur de Cabo Nariz, Chile, añoran sucesiones sedimentarias de antepaís cretácicas tardías a paleocenas de la cuenca de Magallanes.

    Observations of upward lightning from tall objects have been reported since 1939. Interest in this subject has grown recently, some of it because of the rapid expansion of wind power generation. Also, with the increasing number of tall buildings and towers, there will be a corresponding increase in the number of upward lightning flashes from these structures. Reports from recent field observations are beginning to address the nature of upward lightning initiation, but much still needs to be learned. Examples are studies of upward lightning from towers in winter thunderstorms in Japan (Wang and Takagi, 2010; and Lu et al., 2009) and summer thunderstorms in Europe (Miki et al., 2005; Flache et al., 2008; and Diendorfer et al., 2009; Zhou et al., 2011) and in North America (Mazur and Ruhnke, 2011; Hussein et al., 2011; Warner, 2011, and Warner et al., 2011). Up to January 2012, no upward flash had ever been registered in Brazil. With the help of some video cameras, we recorded 15 upward lightning which started from one of the towers located on Peak Jaraguá in the city of São Paulo. This paper describes the first results of this field campaign. A combination of high-speed video and standard definition video were used to record upward lightning flashes from multiple towers in Sao Paulo, Brazil, a city located in southeastern Brazil with a population over 10 million people, an average elevation of around 800 meters above sea level, and a flash density of 15 flashes/km2/year. Observations of 15 upward flashes made with these assets were analyzed along with BrasilDAT Lightning Detection Network and a lightning mapping array (LMA) and electric field sensors.

    This paper describes the practice of sociodrama, a method created by J. L. Moreno in the 1930s, and the Brazilian contemporary socio-psychodrama. In 1970, after the Fifth International Congress of Psychodrama was held in Brazil, group psychotherapy began to flourish both in private practice and hospital clinical settings. Twenty years later, the Brazilian health care system added group work as a reimbursable mental health procedure to improve social health policies. In this context, socio-psychodrama became a key resource for social health promotion within groups. Some specific conceptual contributions by Brazilians on sociodrama are also noteworthy.

    Pero es el resultado de una de sus actividades macrocósmicas, la de la Expedición Humana, lo que nos lo trae aquí esta noche al presentarnos el libro de las grandes Expediciones en Colombia, que él ha titulado “Al Cabo de las Velas-Expediciones Científicas en Colombia, Siglos XVIII, XIX Y XX”.

    Efectivamente los viajes clásicos, tal como hoy los conocemos por los historiadores o los cronistas, se dividieron en “exploraciones” y “expediciones”, según aquellas se dedicaran a recorrer los diferentes territorios y sus accidentes geográficos y a describirlos en forma más o menos detallada para el beneficio de futuros viajeros; mientras que éstas se formaban por grupos selectos, dirigidos a lugares geográficos definidos y dotados de un fin específico, para registrar, colonizar, analizar o explotar sus recursos.

    Esa definición, sin embargo, se confunde en la práctica; tecnológicamente, los viajes marinos sólo se harán posibles cuando el diseño de voluminosas embarcaciones con quilla y timón, con suficiente velamen y capacidad para albergar un número grande de fornidos remeros les permitiera, no sólo transportar las provisiones suficientes de agua, comida, algunas armas e implementos, sino poder sortear las inconsistencias y las inclemencias del tiempo, desde las calmas chichas hasta los huracanes.

    To investigate the biological origin of injectable unfractioned heparin available in Brazilian market by discussing the impact of the profile of commercial products and the changes in heparin monograph on the drug safety. The Anvisa data base for the Registered Products of Pharmaceutical Companies and the Dictionary of Pharmaceutical Specialties (DEF 2008/2009) were searched. A survey with industries having an active permission for marketing the drug in Brazil was conducted. Five companies were granted a permission to market unfractioned heparin in Brazil. Three of them are porcine in origin and two of them are bovine in origin, with only one explicitly showing this information in the package insert. The effectiveness and safety of heparin studied in non-Brazilian populations may not represent the Brazilian reality, since most countries no longer produce bovine heparin. The currently marketed heparin has approximately 10% less anticoagulant activity than that previously produced and this change may have clinical implications. Evidence about the lack of dose interchangeability between bovine and porcine heparins and the unique safety profile of these drugs indicates the need to follow the treatment and the patients' response. Events threatening the patient's safety must be reported to the pharmacovigilance system in each particular country.

    Full Text Available Cutaneous melanoma (CM is responsible for 75% of deaths from malignant skin cancer. The incidence of CM in the southern region of Brazil, particularly in the western region of Santa Catarina, is possibly higher than estimated. In this study, the clinical and epidemiological profile of patients with CM treated in the western region of Santa Catarina was examined. A cross-sectional study was performed with patients diagnosed with CM from January 2002 to December 2009, from 78 counties of the western region of the state of Santa Catarina. Data were collected using a protocol adapted from the Brazilian Melanoma Group and 503 patients were evaluated. The incidence and prevalence of CM found in this region are much higher than those found elsewhere in the country. This fact is most likely due to the phenotypic characteristics of the population and the high incidence of UV radiation in this region due to its location in southern Brazil, as is the case in the countries of Oceania.

Standing out the species Margarites olivaceus (Brown, 1827; Cyclostremiscus caraboboensis Weishord, 1962; Balcis gibba Folin, 1867; Triphora compsa (Dall, 1927; Henrya af. goldmani Bartsh, 1947 and Limaea subovata Jeffreys, 1876 as they have not been previously assigned to Brazil. The analysis of the geographical distribution patterns points out the dominance of the species with thermophiles affinities. This situation evidences the importance of the Brazilian Current in the maintanance of the biogeographical structure of the studied region. However, it is the analysis of the cryophiles species that shows the Cabo Frio region as an ecological filter quite more permeable to the species with thermophile affinities than to the cryophiles ones. The existence of this barrier and the endemism rate (4.27% characterize the region that extends from the south of Cabo Frio as a transition between the two patterns cited above. Therefore they do not corroborate in malacological parameters the proposition made by Palacio (1982 for the individualization of the Paulista Province.

    A need for general physicians, chiefly to deal with health problems in the interior, has made itself felt since 1948. The first two medical residency programs for the training of general physicians were begun in 1976, and today there are 13 such programs. Ten of those programs have been studied in this report, which is based on visits to the establishments where the resident physicians receive training and to some areas served by the programs, and on interviews with education and health officials, alumni of the programs, resident physicians, and coordinators and supervisors of residency programs. "Community general medicine" is the term most widely used in the profession to designate medical practice addressed to the individual, the family and the community and providing total, ongoing and personalized care of the patient. Community general medicine must take account of psychological and socioeconomic factors and interact with the community to collaborate in the solution of its problems. The residency programs in community general medicine are essential for the training of teachers and researchers who will be models to the graduating students and change the undergraduate courses by removing them from the now prevalent overspecialization so as to arrive at a more humane medicine that is more responsive to the health needs of less developed regions. For lack of information on the practice and teaching of community general medicine, attitudes in the medical profession vary from apathetic to sceptical to approving. As a new movement in Brazil, it has great difficulties to overcome, including shortcomings in the training for it and a lack of job openings for graduates. Up to 1982, 174 physicians had completed residencies in community general medicine in Brazil, and about 154 of them are known to have been employed. There are at present 138 physicians attending the 10 programs considered. The regular teaching staff are joined by many professionals in different capacities

    Full Text Available The queen conch Eustrombus gigas is an important fisheries resource in the Caribbean region. In Cuba Island the studies about this resource are very scarce and particularly in the Southeastern regions of the country. With the aim to get important fishery information about this gastropod, adult Queen Conch density and frequency of reproductive activity were evaluated in Cabo Cruz, Cuba, during 2009-2010. Data from three seasons were obtained (rainy, dry and cold fronts periods from three different areas: Farito, Guafe and Laguna. The highest density was observed in cold fronts season (468.5ind./ha and the lowest occurred during the dry season (268.5ind./ha. The highest density was reported at Laguna (520.4ind./ha and the lowest at Farito (290.9ind./ha. In total, 158 reproductive events were observed. The highest frequency was reported in rainy season (36%, followed by dry (9% and cold fronts (5% seasons. Reproductive behavior (mating and egg laying was related to temperature and photoperiod. Reproductive activity was observed during the whole year, which suggests the existence of an important Queen Conch reserve in the Southeastern region of Cuba and an apparently self-sufficient population for recruitment. From our results we may conclude that, the population’s sustainable exploitation is viable if the following management measures are observed: functional zoning within the area, rotation of fishing areas and a closed season. We recommend that the Laguna site should be protected as a reproduction zone and banned for fishing activities.El Eustrombus gigas es un recurso pesquero importante en la región del Caribe. En Cuba, los estudios acerca de este recurso son muy escasos y en la zona Sur-oriental del país son casi nulos.

    Full Text Available OBJECTIVE: This study provides the clinical pathological characteristics of 1301 cases of pediatric/adolescent lymphomas in patients from different geographic regions of Brazil. METHODS: A retrospective analyses of diagnosed pediatric lymphoma cases in a 10-year period was performed. We believe that it represents the largest series of pediatric lymphomas presented from Brazil. RESULTS: Non-Hodgkin lymphomas represented 68% of the cases, including those of precursor (36% and mature (64% cell origin. Mature cell lymphomas comprised 81% of the B-cell phenotype and 19% of the T-cell phenotype. Hodgkin lymphomas represented 32% of all cases, including 87% of the classical type and 13% of nodular lymphocyte predominant type. The geographic distribution showed 38.4% of the cases in the Southeast region, 28.7% in the Northeast, 16.1% in the South, 8.8% in the North, and 8% in the Central-west region. The distribution by age groups was 15-18 years old, 33%; 11-14 years old, 26%; 6-10 years old, 24%; and 6 years old or younger, 17%. Among mature B-cell lymphomas, most of the cases were Burkitt lymphomas (65%, followed by diffuse large B-cell lymphomas (24%. In the mature T-cell group, anaplastic large cell lymphoma, ALK-positive was the most prevalent (57%, followed by peripheral T-cell lymphoma, then not otherwise specified (25%. In the group of classic Hodgkin lymphomas, the main histological subtype was nodular sclerosis (76%. Nodular lymphocyte predominance occurred more frequently than in other series. CONCLUSION: Some of the results found in this study may reflect the heterogeneous socioeconomical status and environmental factors of the Brazilian population in different regions.

    Emergency medicine is developing rapidly in southern Brazil, where elements of both the Franco-German and the Anglo-American models of emergency care are in place, creating a uniquely Brazilian approach to emergency care. Although emergency medical services (EMS) in Brazil have been directly influenced by the French mobile EMS (SAMU) system, with physicians dispatched by ambulances to the scenes of medical emergencies, the first American-style emergency medicine residency training program in Brazil was recently established at the Hospital de Pronto Socorro (HPS) in Porto Alegre. Emergency trauma care appears to be particularly developed in southern Brazil, where advanced trauma life support is widely taught and SAMU delivers sophisticated trauma care en route to trauma centers designated by the state.

Bleached affected almost 50% of coral colonies analyzed in Cabo Branco reefs (Paraiba state in the summer of 2005. The same phenomenon was detected along various coastal reefs in northeastern Brazil during the summer of 2007 and 2008. These events were seasonal, and began with the emergence of pale colonies that became pale-pink and then purple during the rainy months. The patterns and intensity of colonies pigmentation changes varied with the studied sites. The decrease in zooxanthellae density and chlorophyll-a content was quantified in the colonies with their pigmentation pattern altered (bleaching. Microbiological analyses revealed higher densities of bacteria in pink colonies (bleached as compared to brown colonies (normal. Environmental disturbances may lead to the pigmentation changes in Siderastrea spp., but the immediate causes of this phenomenon are not clear and require further investigations.

    Full Text Available Large portions of Brazil′s Northeast have experienced an intense and prolonged drought for the majority of 2010–2013. This drought, along with other droughts that have hit the South in recent years, has sparked a new round of discussions to improve drought policy and management at the federal and state levels. To assist with these efforts, the World Bank recently conducted a series of evaluations on national and sub-national drought preparedness measures and approaches across five country case studies. This particular article presents the Brazilian case study. The work draws from interviews with key experts and stakeholders, as well as document analyses, and focuses on preparedness measures and approaches at the national and one sub-national case; the state of Ceará. The analysis shows that although there is a rich history of drought management throughout Brazil, there are short-term and long-term gaps and opportunities on which decision makers might consider focusing to improve monitoring, forecasting, and early warning systems, vulnerability/resilience and impact assessments, and mitigation and response planning measures.

    This article is an excerpted summary of a speech on female police and domestic violence. The speech was given by a woman affiliated with the Association of Women Workers at an Oxfam workshop in northern Brazil. This organization successfully lobbied for female police, which resulted in more reports of domestic violence, especially rape. The organization is active in 13 counties. Female police are trained and usually given respect by police chiefs. In one city, in 1997, the appointment of female police resulted in registered reports of 387 cases of violence and hospital reports of 503 cases, of which 14% were child rape. During January-April 1998, there were 126 registered cases and 168 hospital cases. Policewomen formed a partnership over the past 2 years with the Human Rights Group and other popular political groups to train female police about laws. The compulsory course focused on four areas: legal concepts, penalties, and procedures on registration of complaints; the Brazilian Penal Code; civil law; and world judicial bureaucracies. Training includes a 1 month internship with the program's lawyer. Over 20 women have completed the course to date. Training in some cases resulted in greater expertise among the female police than their Police Chiefs. Female police have experienced harassment by local authorities.

    Although dogs are considered to be the principal transmitter of rabies in Brazil, dog rabies had never been recorded in South America before European colonization. In order to investigate the evolutionary history of dog rabies virus (RABV) in Brazil, we performed a phylogenetic analysis of carnivore RABV isolates from around the world and estimated the divergence times for dog RABV in Brazil. Our estimate for the time of introduction of dog RABV into Brazil was the late-19th to early-20th century, which was later than the colonization period but corresponded to a period of increased immigration from Europe to Brazil. In addition, dog RABVs appeared to have spread to indigenous animals in Brazil during the latter half of the 20th century, when the development and urbanization of Brazil occurred. These results suggest that the movement of rabid dogs, along with human activities since the 19th century, promoted the introduction and expansion of dog RABV in Brazil.

    Neospora caninum is protozoan parasite with domestic and wild dogs, coyotes and grey wolves as the definitive hosts and many warm-blooded animals as intermediate hosts. It was cultivated and named in 1988. Neosporosis is a major disease of cattle and has no public health significance. Since 1990's N. caninum has emerged as a major cause of abortion in cattle worldwide, including in Brazil. N. caninum also causes clinical infections in several other animal species. Considerable progress has been made in understanding the biology of N. caninum and there are more than 200 papers on this subject from Brazil. However, most of the reports on neosporosis from Brazil are serological surveys. Overall, little is known of clinical neosporosis in Brazil, particularly cattle. The few reports pertain to sporadic cases of abortion with no information on epidemics or storms of abortion. The objective of the present review is to summarize all reports from Brazil and suggest topic for further research, including prevalence of N. caninum oocysts in soil or in canine feces, and determining if there are additional definitive hosts, other than the domestic dog. There is need for a national survey in cattle using defined parameters. Future researches should focus on molecular characterization of N. caninum strains, possibility of vaccine production and relationship between wildlife and livestock epidemiology.

    Full Text Available This article is about the Islam lived and practiced by Muslim communities in Brazil. It attempts to understand the identity that this religion is acquiring in the Brazilian religious field. It discusses the discrepancy between figures presented by the official census and Muslim sources and offers models to think about the emergence of Muslim communities and possible changes due to the entrance of "new Muslims" (converted Brazilians without Muslim origin. Based on empirical data, it discusses the difficulties found and strategies used by the communities. It suggests that Islam in Brazil is starting to put down roots and to have a profile of its own.

  19. Flood model for Brazil

    Looking on the impact of flooding from the World-wide perspective, in last 50 years flooding has caused over 460,000 fatalities and caused serious material damage. Combining economic loss from ten costliest flood events (from the same period) returns a loss (in the present value) exceeding 300bn USD. Locally, in Brazil, flood is the most damaging natural peril with alarming increase of events frequencies as 5 out of the 10 biggest flood losses ever recorded have occurred after 2009. The amount of economic and insured losses particularly caused by various flood types was the key driver of the local probabilistic flood model development. Considering the area of Brazil (being 5th biggest country in the World) and the scattered distribution of insured exposure, a domain covered by the model was limited to the entire state of Sao Paolo and 53 additional regions. The model quantifies losses on approx. 90 % of exposure (for regular property lines) of key insurers. Based on detailed exposure analysis, Impact Forecasting has developed this tool using long term local hydrological data series (Agencia Nacional de Aguas) from riverine gauge stations and digital elevation model (Instituto Brasileiro de Geografia e Estatística). To provide most accurate representation of local hydrological behaviour needed for the nature of probabilistic simulation, a hydrological data processing focused on frequency analyses of seasonal peak flows - done by fitting appropriate extreme value statistical distribution and stochastic event set generation consisting of synthetically derived flood events respecting realistic spatial and frequency patterns visible in entire period of hydrological observation. Data were tested for homogeneity, consistency and for any significant breakpoint occurrence in time series so the entire observation or only its subparts were used for further analysis. The realistic spatial patterns of stochastic events are reproduced through the innovative use of d-vine copula

  20. Sexuality education in Brazil.

    1994-01-01

    The development of a comprehensive program of sex education in Brazilian schools is described in the context of Brazil's culture and traditions such as the Carnival. The influence of Catholicism is explored as is the effect of the behavioral restrictions called for by scientists concerned about sexually transmitted diseases. The Brazilian response to homosexuality is described, and the emergence of a public discussion of sexuality in the media is traced. It is noted that improvements in the status of women have been held in check by a public ridicule of feminism and by the strength of the traditional patriarchal structures which dominate the culture. With this picture given of how the issue of sexuality fits into Brazilian life, the 1980s initiative on the part of the Work and Research Group for Sex Education is described. Opposition to this effort has largely taken the form of passive resistance; even the Catholic Church has not officially protested the sex education program. Details are provided about 1) the selection of teachers, teacher training, and weekly supervisory teacher meetings; 2) the way in which parental permission for student participation was gained; 3) the implementation of the program; 4) the successes achieved; and 5) the difficulties encountered. Finally, it is noted that plans were made to expand the sex education project from the Sao Paulo area to 6 additional large cities in 1994. Also planned is the publication of the Brazilian Guidelines for Comprehensive Sexuality which will explain the sex education methodology and be extremely valuable in the establishment of new projects.

    The Health in Prostitution Project was launched in 1991 in Rio de Janeiro, Brazil. The project offers a multi-year training program of health education designed to both fight the stigmatization of and violence against commercial sex workers and enhance their self-esteem, self-determination, and access to civil rights. The project therefore promotes individual awareness while influencing public opinion and policies. At first, health agents were recruited among women and transvestites who work in street-based sex work. The program was then gradually expanded to include young male sex workers and other locations, such as private parlors, saunas, and escort services. People of all sexes and sexual orientation now comprise the health agent group. The program has a paid staff of five women, three young men, and three transvestites, and approximately 70 sex workers are trained annually. Basic training includes topics such as human sexuality, personal risk assessment, HIV/STD infection, negotiation of safer sex, and STD referral services. Year two training emphasizes reproductive and women's health issues, while year three courses prioritize street work methodologies. Theatrical performances, speaking English as a second language, and performing Bach flower therapy for clients take place during the fourth year. Program trainers include medical specialists, nurses, psychologists, health educators, lawyers, and university students. At least half of the 350 health agents trained thus far are estimated to be currently engaged in paid or voluntary prevention work. Two surveys with female sex workers in 1991 and 1993 found that reported regular condom use increased from 57% to 73%; the health agents are having an effect. The program is constantly evaluated and revised.

    Sera from the patients (N = 10) with schistosomiasis mansoni of the hospital of Federal University of Pernambuco, the Schistosoma mansoni egg-positive (N = 51) and -negative (N = 452) inhabitants in Cabo City area, out-patients (N = 37) of the IMIP hospital and Japanese immigrants (N = 127) in Petrolina City area of northeast Brazil as well as Japanese healthy subjects (N = 30) were examined by serological tests including an enzyme-linked immunosorbent assay with antigens prepared from eggs (ELISA-egg) and adult worms (ELISA-adult). The ELISA with egg or adult antigen correctly identified 100% of the uninfected individuals lived in non-endemic area of schistosomiasis. Moreover, when examined cross-reactivity of our ELISA with sera isolated from 78 subjects infected with various intestinal parasitic infections, only one of these sera reacted with the egg and adult antigens. On the examination of 51 sera from the egg-positive subjects, the ELISA-egg revealed the highest sensitivity (98.0%), whereas a large number of false negative reactions of ELISA-adult, Ouchterlony method using adult antigen, circumoval precipitation and immediate intradermal skin test were observed. A low sensitivity of these serologic tests except for ELISA-egg appears to be primarily due to their inability to detect antibody in the sera from egg-positive infantiles. There was no positive correlation between the absorbance values of these two types of ELISA among the sera isolated from ELISA-positive subjects. Rather, by the reactivity of these sera to egg or adult antigen, they could be divided into two subgroups; one reacted more positively with egg antigen and the other with adult antigen. Moreover, it was confirmed that the sera from young subjects (under 20 years old) appear to be highly reactive to the egg antigen than did aged ones. These data suggest that the ELISA with egg antigen, but not with the adult antigen, appears to be useful for the serological survey of schistosomiasis mansoni

    Implying large residence times and complex water origins deep coastal aquifers are of particular interest as they are remarkable markers of climate, water use and land use changes. Over the last decades, the Metropolitan Region of Recife (Brazil) went through extensive environmental changes increasing the pressure on water resources and giving rise to numerous environmental consequences on the coastal groundwater systems. We analysed the groundwater of the deep aquifers Cabo and Beberibe that are increasingly exploited. The processes potentially affecting groundwater residence times and flow paths have been studied using a multi-tracer approach (CFCs, SF6, noble gases, 14C, 2H and 18O). The main findings of these investigations show that: (1) Groundwaters of the Cabo and Beberibe aquifers have long residence times and were recharged about 20,000 years ago. (2) Within these old groundwaters we can find palaeo-climate evidences from the last glacial period at the tropics with lower temperatures and dryer conditions than the present climate. (3) Recently, the natural slow dynamic of these groundwater systems was significantly affected by mixing processes with contaminated modern groundwater coming from the shallow unconfined Boa Viagem aquifer. (4) The large exploitation of these aquifers leads to a modification of the flow directions and causes the intrusion through palaeo-channels of saline water probably coming from the Capibaribe River and from the last transgression episodes. These observations indicate that the current exploitation of the Cabo and Beberibe aquifers is unsustainable regarding the long renewal times of these groundwater systems as well as their ongoing contamination and salinisation. The groundwater cycle being much slower than the human development rhythm, it is essential to integrate the magnitude and rapidity of anthropogenic impacts on this extremely slow cycle to the water management concepts. - Highlights: • Study of anthropogenic impacts

  12. Brazil The Duck Lagoon

    2002-01-01

    This Multi-angle Imaging SpectroRadiometer (MISR) image of Brazil covers an area of about 298 kilometers x 358 kilometers, and was captured by the instrument's vertical-viewing (nadir) camera on December 27, 2001. The 'Lagoa dos Patos', in the Brazilian state of Rio Grande do Sul, translates to 'the Duck Lagoon'. It was named by 16th century Jesuit settlers, who asked the King of Spain to grant them title to the lagoon so that they could breed ducks. The King consented, but revoked his edict when he discovered that the 'duck-pond' (measuring about 14,000 square kilometers) was one of the largest lagoonal systems in the world. Note the sediment plume emanating from the southern end of the lagoon. Sailors in the 16th century imagined this outlet to be the mouth of a large river. Early Portuguese explorers mistook the entrance to the lagoon for the mouth of a great river and called it the Rio Grande. A series of wave-like points and curls form 'cusps' on the inner shores of the lagoon. The lagoon's characteristics change with short-term tide-induced cyclic perturbations, and with longer term large scale meteorological conditions. The distinctive wavelike 'cusps' along the inner shores result from the circulation, erosion and accumulation of sediments driven by wind and tidal action. The El Nino Southern Oscillation (ENSO) circulation affects precipitation amount and continental runoff, thereby changing the contents of the lagoon waters. High rainfall and increased freshwater discharge during El Nino events correspond with elevated dissolved nutrient concentrations and increased phytoplankton growth. La Nina years are dry and the associated low rainfall reduces the freshwater recharge to the lagoon, causing an increase in salinity. Occasional blooms of toxic cyanobacteria (Microcystis aeruginosa), have been registered in the lagoon when nutrient concentrations are elevated. A number of reeds and grasses are important to the lagoon estuary, including widgeon grass

    1997-01-01

    Brazil is a recently industrialised country with marked contrasts in social and economic development. The availability of public/private services in its different regions also varies. Health indicators follow these trends. Occupational health is a vast new field, as in other developing countries. Occupational medicine is a required subject in graduation courses for physicians. Specialisation courses for university graduated professionals have more than 700 hours of lectures and train occupational health physicians, safety engineers and nursing staff. At the technical level, there are courses with up to 1300 hours for the training of safety inspectors. Until 1986 about 19,000 occupational health physicians, 18,000 safety engineers and 51,000 safety inspectors had been officially registered. Although in its infancy, postgraduation has attracted professionals at university level, through residence programmes as well as masters and doctors degrees, whereby at least a hundred good-quality research studies have been produced so far. Occupational health activities are controlled by law. Undertakings with higher risks and larger number of employees are required to hire specialised technical staff. In 1995 the Ministry of Labour demanded programmes of medical control of occupational health (PCMSO) for every worker as well as a programme of prevention of environmental hazards (PPRA). This was considered as a positive measure for the improvement of working conditions and health at work. Physicians specialising in occupational medicine are the professionals more often hired by the enterprises. Reference centres (CRSTs) for workers' health are connected to the State or City Health Secretariat primary health care units. They exist in more populated areas and are accepted by workers as the best way to accomplish the diagnosis of occupational diseases. There is important participation by the trade unions in the management of these reference centres. For 30 years now employers

    2017-03-01

    Full Text Available ABSTRACT Two Coryphaena hippurus morphotypes (dourado and palombeta are found along the Brazilian coast and are considered by Rio de Janeiro’s fisherman and fishmongers as two different species. Furthermore, these morphotypes are commercialized under different values and suffer different fishing pressure. Therefore, a definition of their taxonomic status is an important economic and biological matter. In order to investigate this problem, allozyme electrophoresis method was undertaken for seventeen loci on 117 individuals of C. hippurus sampled at Cabo Frio/RJ (Brazil. The data indicate homogeneity between the morphotypes gene pools. Nevertheless, differences were found for genetic variation among dourado and palombeta, especially due to alcohol dehydrogenase locus. Natural selection hypothesis is discussed in explaining these findings.

  3. A study of atmospheric diffusion from the LANDSAT imagery. [pollution transport over the ocean

    1981-01-01

    LANDSAT multispectral scanner data of the smoke plumes which originated in eastern Cabo Frio, Brazil and crossed over into the Atlantic Ocean, are analyzed to illustrate how high resolution LANDSAT imagery can aid meteorologists in evaluating specific air pollution events. The eleven LANDSAT images selected are for different months and years. The results show that diffusion is governed primarily by water and air temperature differences. With colder water, low level air is very stable and the vertical diffusion is minimal; but water warmer than the air induces vigorous diffusion. The applicability of three empirical methods for determining the horizontal eddy diffusivity coefficient in the Gaussian plume formula was evaluated with the estimated standard deviation of the crosswind distribution of material in the plume from the LANDSAT imagery. The vertical diffusion coefficient in stable conditions is estimated using Weinstock's formulation. These results form a data base for use in the development and validation of meso scale atmospheric diffusion models.

  6. Decentralization and REDD+ in Brazil

    Directory of Open Access Journals (Sweden)

    Fabiano Toni

    2011-01-01

    Full Text Available Recent discussions on REDD+ (Reducing Emissions from Deforestation and Forest Degradation, plus conservation, sustainable management of forests and enhancement of forest carbon stocks have raised optimism about reducing carbon emissions and deforestation in tropical countries. If approved under the United Nations Framework Convention on Climate Change (UNFCCC, REDD+ mechanisms may generate a substantial influx of financial resources to developing countries. Some authors argue that this money could reverse the ongoing process of decentralization of forest policies that has spread through a large number of developing countries in the past two decades. Central states will be accountable for REDD+ money, and may be compelled to control and keep a significant share of REDD+ funds. Supporters of decentralization argue that centralized implementation of REDD+ will be ineffective and inefficient. In this paper, I examine the relation between subnational governments and REDD+ in Brazil. Data show that some state governments in the Brazilian Amazon have played a key role in creating protected areas (PAs after 2003, which helped decrease deforestation rates. Governors have different stimuli for creating PAs. Some respond to the needs of their political constituency; others have expectations to boost the forest sector so as to increase fiscal revenues. Governors also have led the discussion on REDD+ in Brazil since 2008. Considering their interests and political power, REDD+ is unlikely to curb decentralization in Brazil.

    Billfishes, such as marlin, are top pelagic predators that play an important role in maintaining the stability of marine food webs. Notwithstanding the importance of these species, there remain gaps in our knowledge on their movements, foraging, and trophic status in the early stage of life. We measured the δ(13)C and δ(15)N values in each annual growth band deposited in the dorsal spine from striped marlin caught off Cabo San Lucas, Mexico, to produce retrospective isotopic profiles that would enable us to detect any significant isotopic changes across development. The samples were analyzed using an elemental analyzer coupled to an isotope ratio mass spectrometer. There was no relationship between the size of striped marlin and the δ(15) N values. Differences in δ(15)N mean values across different age classes were not significant and the variation in δ(15)N values through the marlins' life cycle was less than 2‰. However, the mean δ(15)N values between individuals varied by up to 6‰. The δ(13)C values increased as a function of age, and the mean δ(13)C values varied significantly between age classes. Fin spines can be used to construct retrospective isotopic histories for the investigation of trophic dynamics and migratory histories in billfishes, for which population dynamics are often poorly known.

  14. Phylogeography of four frog species in forest fragments of northeastern Brazil--a preliminary study.

    Carnaval, Ana Carolina O Q

    2002-11-01

    I contrast mitochondrial DNA genealogies based on 612 bp of the cytochrome b gene across four co-distributed species of frogs in Northeastern Brazil. They are Hyla albomarginata, Hyla branneri, Proceratophrys boiei, and Scinax nebulosus. Samples were collected from the core or edge of six rainforest remnants in the states of Pernambuco and Alagoas. Three fragments are located within the humid Atlantic Forest morphoclimatic domain (municipalities of Cabo de Santo Agostinho, Ibateguara, and Jaqueira), two are located in the transition zone between the Atlantic Forest domain and the semi-arid Caatinga (Caruaru and Timbaúba), and one is found within the Caatinga (Brejo da Madre de Deus). Results show that local patterns and levels of genetic diversity are influenced by taxon-specific habitat requirements. Populations of the montane, closed-canopy species P. boiei show strong geographical structure, reflecting barriers to gene flow that predate human-driven habitat destruction. Species occurring along forest edges, such as H. albomarginata and S. nebulosus, show genetic patterns similar to those of P. boiei, but lower levels of genetic divergence. The more generalist Hyla branneri shows no geographic pattern. The data are in agreement with distribution and fossil data gathered for other groups of organisms, suggesting that mesic forests occupied the currently arid Caatinga in the recent past.

    The macrofauna (endo- and epi-biotic) associated to the sponge Mycale ( Carmia) microsigmatosa Arndt, 1927 was studied at three sites in Rio de Janeiro State, Brazil (Arraial do Cabo, Niterói, and Rio de Janeiro). A total of 2235 individuals (over 1 mm long) of 75 invertebrate species were found associated to 19 specimens of the sponge. The most abundant and diverse taxa were the crustaceans (83%, 31 spp.), polychetes (10%, 18 spp.), and molluscs (3.7%, 15 spp.). Cnidarians, platyhelminthes, ascidians, echinoderms, pycnogonids, bryozoans, and sponges were also represented. Amphipod crustaceans were the dominant group, comprising 61% of all individuals collected. Species richness and abundance of associated fauna were highly correlated with sponge volume, but diversity and evenness were not. The site of collection influenced the species composition of the fauna associated to M. microsigmatosa but did not change significantly its diversity, abundance, richness, and dominance patterns of higher taxa. Pregnant females and juvenile stages of 29% of the species associated, including crustaceans, molluscs, echinoderms, and pycnogonids were frequently found inside M. microsigmatosa. Although many of these organisms do occur and reproduce in other habitats outside the sponge as well, M. microsigmatosa is also important for their reproduction and survivorship, thus contributing for the maintenance of biodiversity in Southwestern Atlantic sublittoral rocky shores.

    Full Text Available Geomorphic surfaces that present soils derived from basic rocks under warm and humid climate are unique scenarios for studying tropical soils. This paper aimed to characterize and classify two pedons derived from basalt at the Atlantic Forest Zone, Pernambuco State, Northeastern coast of Brazil. Two representative pedons (P1 and P2 were selected on a hillslope at the Cabo de Santo Agostinho municipality. Field macromorphological descriptions were carried out and soil horizon were sampled for physical, chemical, mineralogical and micromorphological characterization. The soils were classified, according to the Brazilian System of Soil Classification (and US Soil Taxonomy as: "Latossolo Vermelho-Amarelo distroférrico argissólico" (Typic Hapludox (P1 and "Nitossolo Vermelho distroférrico típico" (Rhodic Paleudult (P2. Pedon 1 differs from Pedon 2 in some aspects. For instance, P1 presents more yellowish colors, absence of clay illuviation, more friable consistence and the prismatic structure undergoes transformation to angular and subangular blocks. Pedon 2 presents ferri-argilans and leptocutans which indicate that vertical and lateral illuviation of clay is an active process in their formation. These chemically poor and mineralogically uniform soils are a result of the high temperature and rainfall of the studied area.

  4. Lateritic nickel deposits of Brazil

    de Oliveira, S. M. Barros; Trescases, J. J.; Melfi, A. José

    1992-03-01

    Many nickel deposits are known in Brazil, accounting for about 350 · 106 tons of ore with an average of 1.5% Ni. All are of the lateritic type. These deposits are scattered throughout the country, being rarer in the Northeastern Region and in the South, below 25 °S latitude. They are mainly associated with mafic-ultramafic massifs of large dimensions and ultramafic alkaline complexes, and occur in climatic regions of contrasting seasons. The weathering profile developed over the fresh rock consists, from bottom to top, of the following horizons: altered rock, coarse saprolite, argillaceous saprolite, ferruginous saprolite and lateritic overburden. The thickness of each horizon varies from one deposit to another, the whole profile generally exceeding 20 m. The saprolitic horizons with inherited minerals (serpentine, chlorite) or neoformed minerals (smectites) constitute the silicated nickel ore and are thicker were climatic conditions are drier; the ferruginous upper horizons made up of iron oxide-hydroxides are more developed in more humid regions. In Brazil, the silicated ore generally prevails over the oxidized ore. The main Ni-bearing minerals are serpentine, smectite, garnierite and goethite. The lateritic nickel deposits of Brazil may be correlated with two erosion surfaces, corresponding to the Sul Americano (Lower Tertiary) and Velhas (Upper Tertiary) levelling cycles. The degree of dismantling of the higher and more ancient surface and the consequent development of the Velhas Surface control the position of the nickel accumulation in the landscape. Thus, the deposits may be found either in the lowlands or in the highlands, where they are always covered by a silcrete layer. The alteration profiles in the Brazilian lateritic nickel deposits are broadly similar to those described elsewhere in the world. However, they present two characteristic features: the silicated ore prevails over the oxidized ore, and a silicified layer covers the profies developed on

    Full Text Available The rural population lives in socioeconomic inequality conditions motivated by several problems, including an insufficient sewage systems and water supply, these, sometimes, most responsibles by the appearance of waterborne diseases that contribute to the rise of child mortality and other problems. Rural areas in Brazil are defined by opposition and exclusion in urban areas. This definition is arbitrary and physical-geographic, not considering the social and economic processes involving the territories. This study purposed to verify, by means of sociodemographic aspects, environmental sanitation and main grievances/diseases importance for public health of the population from forest field and water, if the most rural municipalities (MMR are more precarious than the more urban (MMU. To this end, was carried out a descriptive study based on secondary sources (Atlas of Human Development in Brazil, IBGE census, PNAD and Sinan. Among the results, it follows that the rural population identified by IBGE boils down to 15.6% of Brazil’s population. In 29% of the municipalities, the population living in rural areas exceeds the city. The higher frequencies from IDMH very low are for MMR, while the higher frequency from IDMH very high and high are for MMU. In health, the MMR also exhibit deficiency. It was observed high incidence rates of diseases related to poor conditions of sanitation. From these results, it was identified a more precarious health profile in MMR when compared to MMU.

    Brazil has high rates of leprosy case detection, especially in the northern and west-central areas of the country. Effective decentralisation of routine treatment for leprosy has gathered pace since the year 2000 and this has improved access for patients, leading to a peak in new case detection in 2003 and a gradual decline thereafter. This is in parallel with specific government programmes aimed at poverty reduction. Disability prevention and surveillance for drug resistance remain important tasks within the leprosy control programme, in which six key referral centres lead the way.

    Brazil is a large country with a wide diversity of landscapes and geological features and has been an important world producer of mineral resources. Despite this, until the 90's of last century, there has not been much concern and policies about geological heritage and geoconservation. Only at the end of the century the National Geological Service (CPRM) included the physical characterization of areas with geotouristic interest in its mission of generation and diffusion of geological information. In 1997, was created the Brazilian Commission of Geological and Paleobiological Sites (SIGEP, http://sigep.cprm.gov.br), responsible for the assessment, description and publicizing the sites of geological heritage. This is by now the most comprehensive and relevant initiative to protect the national heritage. It is composed by a fully accessible national database composed by 167 certified sites presented as scientific papers. Furthermore, a web-based applicative for the inventory and protection of geological heritage sites is being developed by the National Geological Service. The wider knowledge about geological heritage can be a useful tool for its conservation and this has been an important goal in the creation of protected areas, by means of environmental education and tourism. In Brazil, actions, research and publications about the subject have increased in the last five years, as well as the outreach and responsible use of the geological heritage. Scientific meetings, conferences and courses are growing and spreading around the country. The main scientific meeting has been the Brazilian Symposium of Geological Heritage that in its second edition (2013) had more than 200 papers presented. At that meeting it was also created the Association in Defence of the Geomining Heritage and the Association of Aspiring Geoparks. Brazil has only one geopark in the Unesco's Global Geopark Network, that is the Araripe Geopark, created in 2006. By the moment, propositions are being

    The rising concerns about global warming and energy security have spurred a revival of interest in nuclear energy, giving birth to a 'nuclear power renaissance' in several countries in the world. Particularly in Brazil, in the recent years, the nuclear power renaissance can be seen in the actions that comprise its nuclear program, summarily the increase of the investments in nuclear research institutes and the government target to design and build the Brazilian Multipurpose research Reactor (BMR). In the last 50 years, Brazilian research reactors have been used for training, for producing radioisotopes to meet demands in industry and nuclear medicine, for miscellaneous irradiation services and for academic research. Moreover, the research reactors are used as laboratories to develop technologies in power reactors, which are evaluated today at around 450 worldwide. In this application, those reactors become more viable in relation to power reactors by the lowest cost, by the operation at low temperatures and, furthermore, by lower demand for nuclear fuel. In Brazil, four research reactors were installed: the IEA-R1 and the MB-01 reactors, both at the Instituto de Pesquisas Energeticas Nucleares (IPEN, Sao Paulo); the Argonauta, at the Instituto de Engenharia Nuclear (IEN, Rio de Janeiro) and the IPR-R1 TRIGA reactor, at the Centro de Desenvolvimento da Tecnologia Nuclear (CDTN, Belo Horizonte). The present paper intends to enumerate the characteristics of these reactors, their utilization and current academic research. Therefore, through this paper, we intend to collaborate on the BMR project. (author)

  14. Using MODIS True-Color 250 m Remote Sensing Data to Assess Interannual Variability of Suspended Matter over Southeastern Brazilian Continental Shelf

    Continental shelf is the final destination of terrigenous sediments drained by rivers and estuaries, forming a mass of water drifting over the shelf due to its differential density from underlaying salty oceanic waters, forming a coastal plume. On the Southeastern Brazilian Continental Shelf, Cabo Frio region represents the limit between Santos and Campos basin oil reserves. The continental drainage in this area is not expressive, nevertheless presents a complex interaction between the western boundary Brazil Current (BC) and shelf border mechanisms providing amid-shelf intrusion and a coastal upwelling of South Atlantic Central Water (SACW) over the shelf. Satellite images of the region shows expressive shelf plumes with sedimentary contributions from Paraiba do Sul river located approximately 180 km northward of Cabo Frio, as well as from Guanabara bay, located 150 km westward of Cabo Frio. In order to understand the role of plumes in sedimentary processes over the continental shelf, this study analyzed 10 years of MODIS true-color 250 m remote sensing data in order to understand the temporal variability of the shelf front and the area of plumes. The remote data were obtained from the Aerosol Robotic Network and USDA Foreign Agricultural Service subsets. Selected 17% of daily images were cloud-free to allow shelf plumes to be delimited and processed to enhancement of features as well as land masking, geo-referencing, and daily area calculation on pixel basis. During austral winter (dry season) the plumes get its maximum extension in area over the shelf, suggesting that the mechanism of sediment transport is connected with high energetic wave-wind interactions on the coast followed by wind-driven dispersion less than continental drainage. The interannual pattern shows a general decreasing trend, mainly in the last 4 years, associated with sediment availability on the inner shelf, which is driven by river discharge during the austral summer (rain season).

    Brazil is the 10th largest energy consumer in the world and the third largest in the Western Hemisphere, behind the United States and Canada. Total primary energy consumption in Brazil has increased significantly in recent years; and over the past decade, Brazil has made great strides in increasing its total energy production, particularly oil. Brazil has the second-largest crude oil reserves in South America (behind Venezuela), and is one of the fastest growing oil producers in the world. According to United States Energy Information Administration (EIA), Brazil had 12.2 billion barrels of proven oil reserves in 2008. In 2007, Brazil's state owned Petroleo Brasileiro S.A. (PETROBRAS) announced that it had discovered an estimated 5-8 billion barrels of recoverable reserves (including both oil and natural gas) in the Tupi field, located in the Santos Basin. In 2008, subsequent discoveries were announced, to include Jupiter and Carioca (aka Sugar Loaf). Although PETROBRAS has yet to confirm the size of the discoveries, some industry analysts estimate the total extent of recoverable oil and natural gas reserves in the entire pre-salt layer have approached 40 to 80 billion barrels of oil equivalent. The reserves occur below a salt zone that is estimated to be 7,000 meters below the ocean surface. However, Brazil faces many challenges to recover the hydrocarbons to include technical, political, fiscal, and infrastructure hurdles. In spite of the challenges ahead, these discoveries transformed the nature and focus of Brazil's oil industry, economy, and future; and the potential impact of the pre-salt discoveries upon world oil markets is vast. The purpose of this paper is to discuss how the recent discoveries will affect Brazil's future and the impact it will have on the global energy world. (author)

    Full Text Available The taeniasis-cysticercosis complex is a long known zoonotic parasitosis characteristic of underdeveloped countries. In addition to its public health significance, this parasitosis is cause of economic losses to the beef production chain, and synonymous of technical inadequacy in relation to the adoption of Good Agricultural Practices. The occurrences of both human teniasis and bovine cysticercosis could and should be controlled with basic sanitary measures. However, there is much variation in the occurrence of the disease in cattle, characterizing a low rate of technical development as well as problems related to the adoption of basic sanitation measures. This review describes, in details, the causative agent and its epidemiological chain, besides raising current information about the occurrence of bovine cysticercosis in different regions of Brazil, aiming at the adoption of prophylactic measures by different segments responsible.

    After a general survey of botanical exploration in Amazonia in the past and a summary of the present situation, an account is given of the work carried out in the field and the herbarium is search of plant species of potential therapeutic interest. The potential resources of these vast forests are far from being completely explored and still contain a number of unstudied species. Despite the low probability of major discoveries in this field, a promising approach involves the rational collection of data on traditional medicine, the precise identification of species utilized, and the scientific evaluation of their true properties. As an example, a short list of plants commonly utilized for folk medicine in Amazonia and north-eastern Brazil illustrates the importance of phytotherapy for peoples often deprived of other therapeutic means.

    Full Text Available Since the end of the 1990s, Brazil has succeeded in implementing and developing an economic model based on an inflation target model to keep domestic prices under control, a flexible exchange rate and a commitment to ensuring the solvency of the public sector. This model was initially adopted during Fernando Henrique Cardoso’s second term as president, and subsequently maintained and refined during Luis Inácio Lula da Silva’s two terms. Its development will certainly continue under the presidency of Dilma Rousseff. The consensus on this economic model and the relative dissociation of political and economic cycles have facilitated the stabilisation of the domestic environment and the acceleration of economic growth.

El estudio se centra en la evaluación de los flujos migratorios a partir de los expedientes de autorizaciones iniciales de residencia y trabajo por cuenta ajena concedidos en el año 2005 y sus posteriores renovaciones en 2006 y 2008. Podría decirse que el proceso fue un éxito desde el punto de vista de la gestión y de los resultados obtenidos, ya que se trató del mayor proceso de afloramiento de economía sumergida en Europa de los últimos 40 ó 50 años, permitiendo a corto plazo la inserción de más de medio millón de trabajadores en el sistema económico productivo y en el régimen de la Seguridad Social. El 66% de los inmigrantes han mantenido su empleo hasta comienzos de 2009, a pesar de la crisis económica de los últimos años. The purpose of this study is to evaluate the effects of the 2005 Spanish government’s immigrant regularization policy, examinating whether that public policies were successful and analyzing their results up to now. The analysis is based on the migratory flows assessment taking as a starting point the initial residence and employment permissions released in 2005 and their renewals in 2006 and 2008. We can affirm that the process was successful according to the management and the achievements: it was the largest process showing up irregular economy in Europe in the last 40 or 50 years, allowing, in the short term, the labor integration of more than half a million workers. Sixty six percent of these workers succeeded in keeping their jobs up to 2009, despite of the current economic crisis.

    Urbanization and education have brought numerous changes in societies around the world. One change is the contact of different groups, often with an attendant increase in intergroup marriage. In this paper we examine the intergroup intermarriage in Brazil in the context of changing urbanization and education. While intergroup marriage has been intensively examined in the United States, the topic has received less attention in Brazil. We use census data from 1991 and 2000, and national survey ...

    Full Text Available A total of 117 species of freshwater decapod crustaceans are known from Brazil. Knowledge regarding the fauna of Decapoda from inland waters in the state of Bahia, northeast Brazil, is incipient. In spite of its wide territory and rich hydrographic net, only 13 species of limnetic decapods have been reported from that state. The objective of this contribution was to survey decapod crustaceans of some hydrographic basins in southeastern Bahia. The material described herein was obtained in samplings conducted between 1997 and 2005. voucher specimens were deposited in the carcinological collections of the Museu de Zoologia, Universidade Estadual de Santa Cruz, Ilhéus, Brazil, and Departamento de Oceanografia, Universidade Federal de Pernambuco, Recife, Brazil. A total of 13 species was collected. The carideans were represented by the atyids Atya scabra (Leach, 1815 and Potimirim potimirim (Müller, 1881 and the palaemonids Macrobrachium acanthurus (Wiegmann, 1836, M. amazonicum (Heller, 1862, M. carcinus (Linnaeus, 1758, M. heterochirus (Wiegmann, 1836, M. jelskii (Miers, 1877, M. olfersi (Wiegmann, 1836, and Palaemon (Palaemon pandaliformis (Stimpson, 1871. The brachyurans were represented by the portunids Callinectes bocourti A. Milne-Edwards, 1879 and C. sapidus Rathbun, 1895, the trichodactylid Trichodactylus fluviatilis Latreille, 1828 and the panopeid Panopeus rugosus A. Milne-Edwards, 1881. Macrobrachium heterochirus represents a new record from Bahia, and M. amazonicum is reported for the first time in southeast Bahia. The occurrence of two extreme different forms of T. fluviatilis was observed. Form A is characterized by the frontal margin of carapace bordered by conspicuous granules, the anterolateral margin provided with developed teeth plus granules, and the posterolateral margin provided with granulation similar to that found on the front. In form B the frontal margin is smooth or has an inconspicuous granulation; the anterolateral

    Full Text Available The Brazilian continental shelf, with about 8.000 km length, includes several climatic zones expressed in differentiated solid and liquid sediment input. Excepting the important input of sediments and nutrients from the Amazon in the North and the Prata in the South the rest of the shelf is characterized by low productivity due the reduced availability of nutrients. Considering the morphology of the bottom and fishing equipment, the shelf can be divided into two regions: north of Cabo Frio, with warm waters, irregular carbonate bottom, with fishery predominantly through long line and traps; and Southwest of Cabo Frio, with cold waters, flat bottom and fishery predominantly through fishing nets.

    Alfaia, Raquel Greice de Souza Marotta; Costa, Alyne Moraes; Campos, Juacyara Carbonelli

    2017-12-01

    The production of municipal solid waste (MSW) represents one of the greatest challenges currently faced by waste managers all around the world. In Brazil, the situation with regard to solid waste management is still deficient in many aspects. In 2015, only 58.7% of the MSW collected in Brazilian cities received appropriate final disposal. It was only as late as 2010 that Brazil established the National Policy on Solid Waste (NPSW) based on the legislation and programmes established in the 1970s in more developed countries. However, the situation with regard to MSW management has changed little since the implementation of the NPSW. Recent data show that, in Brazil, disposal in sanitary landfills is practically the only management approach to MSW. Contrary to expectations, despite the economic recession in 2015 the total annual amount of MSW generated nationwide increased by 1.7%, while in the same period the Brazilian population grew by 0.8% and economic activity decreased by 3.8%. The article describes the panorama with regard to MSW in Brazil from generation to final disposal and discusses the issues related to the delay in implementing the NPSW. The collection of recyclable material, the recycling process, the application of reverse logistics and the determination of the gravimetric composition of MSW in Brazil are also addressed in this article. Finally, a brief comparison is made between MSW management in Brazil and in other countries, the barriers to developing effective waste disposal systems are discussed and some recommendations for future MSW management development in Brazil are given.

    2011-01-01

    This paper describes the Brazilian health system, which includes a public sector covering almost 75% of the population and an expanding private sector offering health services to the rest of the population. The public sector is organized around the Sistema Único de Saúde (SUS) and it is financed with general taxes and social contributions collected by the three levels of government (federal, state and municipal). SUS provides health care through a decentralized network of clinics, hospitals and other establishments, as well as through contracts with private providers. SUS is also responsible for the coordination of the public sector. The private sector includes a system of insurance schemes known as Supplementary Health which is financed by employers and/or households: group medicine (companies and households), medical cooperatives, the so called Self-Administered Plans (companies) and individual insurance plans.The private sector also includes clinics, hospitals and laboratories offering services on out-of-pocket basis mostly used by the high-income population. This paper also describes the resources of the system, the stewardship activities developed by the Ministry of Health and other actors, and the most recent policy innovations implemented in Brazil, including the programs saúde da Familia and Mais Saúde.

    Full Text Available OBJECTIVE: to estimate the prevalence of contraceptive use and associated factors among adolescents attending public schools on Santiago Island, Cape Verde. METHODS: a cross-sectional study was carried out with 368 sexually active adolescents aged 13-17years attending eight public elementary and high schools, randomly selected, on Santiago Island, Cape Verde, between January and March 2007. Poisson regression with robust variance was used for the multiple analysis of risk factors, at a 5% level of significance. RESULTS: among 368 adolescents, 69.3% reported having used a contraceptive method during the last act of sexual intercourse. The most frequently used method were condom (94.9% and pill (26.4%. Factors significantly and positively associated with contraceptive use were: living in the capital (PR=1.23; CI95%: 1.07; 1.39; having dated and had sexual intercourse (PR =1.53; CI95%: 1.14;2.06; and having more than nine years of schooling (PR=1.19; CI95%: 1.02; 1.38. CONCLUSIONS: more educated adolescents who studied in Praia (the capital city and were dating at the time of the study were more likely to use contraception. The high prevalence of condom use and the association between contraception use and years of schooling among adolescents may indicate that sexual and reproductive health policies have produced positive outcomes that may account for the decrease in HIV infection.OBJETIVO: estimar a prevalência do uso de métodos anticoncepcionais (MAC e fatores associados entre adolescentes de escola pública na ilha de Santiago em Cabo Verde.

  1. Women's motivation to become dentists in Brazil.

    Science.gov (United States)

    Kfouri, Maria G; Moyses, Samuel J; Moyses, Simone Tetu

    2013-06-01

    There has been a marked increase of women in dentistry in Brazil and in many countries around the world. The behavioral mechanisms behind the choice of career differ between men and women, and the inclination to care for others is thought by some to be more present in women than it is in men. This article discusses the reasons that lead women to choose dentistry as a profession in Brazil and the impact of feminization on the current and future profile of the profession, based on the ethics of care. The authors' review of the relevant literature published between 2000 and 2011, primarily in Brazil, suggests that whereas men have tended to choose dentistry as a good business opportunity, women have tended to base their decision on relations with other people and the flexibility of practicing the profession. Many women dentists have been found to decide to work fewer hours, report more interruptions in their activities, and have less preference to work in private practice than men dentists. In the view of service users and dental auxiliaries in Brazil, women dentists invest more time in their patients and communicate in a more pleasant, sensitive, and friendly manner. The conclusion suggests that characteristics often associated with women can affect the dental profession in Brazil by introducing greater concern with the promotion of health and other people's well-being in contrast to traditional dentistry based on curative procedures.

    The natural history of multiple sclerosis (MS) in Brazil has been available in different regions of country. There is no nationwide population-based studies that express general data in Brazil. To review and synthesize available data about MS in Brazil. Systematic review was performed through a search of medical literature databases to identify Brazilian studies published during 1990-2012. PubMed, SciELO, and Lilacs. "Brazil" or "Brazilian" combined with the following terms: "multiple sclerosis", "clinical profile", "demographic profile", "natural history", "clinical course", "pediatric", or "familial form". In total of 45 pediatric and 1922 adult patients, the median age at onset was 10 years in pediatric patients and 32 years in adult patients. Women were more affected. Motor-control complaints and relapsing-remitting phenotype at onset were the most common. Predictors to disability and progression were number of relapses during the first year of disease, older age, male gender and African ancestry. The profile of the MS in Brazilian seems to correspond to that observed in high-MS-prevalence areas. African ancestry is a risk factor to disability and progression early. In Brazil, factors that limit MS incidence do not interfere with the clinical pattern and outcomes. Copyright © 2016 Elsevier B.V. All rights reserved.

  6. Brazil's sugarcane boom could affect regional temperatures

    Schultz, Colin

    2013-04-01

    With the world seeking to cut its dependence on fossil fuels, the use of bioethanol and other biofuels is on the rise. In Brazil, the second largest producer and consumer of bioethanol, this has led to a boom in sugarcane production. Based on new laws and trade agreements, researchers expect Brazil's production of sugarcane-derived ethanol to increase tenfold over the next decade, with considerable land being converted for growing sugarcane. Much of this expansion is expected to come at a loss of some of the country's cerrado savannas. So while a major aim of the turn to biofuels is to reduce the transfer of carbon to the atmosphere and mitigate global climate change, the shifting agricultural activity could have direct consequences on Brazil's climate by changing the region's physical and biogeochemical properties.

    Directory of Open Access Journals (Sweden)

    Marcos Aurelio Guedes de Oliveira

    2010-01-01

    Full Text Available There have been two key initiatives taken in the last two decades in Brazil to create a counter-hegemonic project for the country. One initiative resulted from Brazil's business community and high-level State bureaucracy and aimed at forming a regional economic and political bloc that would guarantee and enlarge a relative independence from the hegemonic powers. The other resulted from the emergence of the new unionist movement in São Paulo and from the formation of Partido dos Trabalhadores and aimed at promoting radical democratization and reducing social exclusion. Both initiatives have created policies and changes that have converged to enhance Brazil's counter-hegemonic position as a regional and emerging power.

    This paper describes a joint US/Brazil pilot project for rural electrification, whose major goals are: to establish technical, institutional, and economic confidence in using renewable energy (PV and wind) to meet the needs of the citizens of rural Brazil; to establish on-going institutional, individual and business relationships necessary to implement sustainable programs and commitments; to lay the groundwork for larger scale rural electrification through the use of distributed renewable technologies. The projects have supported low power home lighting systems, lighting and refrigeration for schools and medical centers, and water pumping systems. This is viewed as a long term project, where much of the equipment will come from the US, but Brazil will be responsible for program management, and sharing data gained from the program. The paper describes in detail the Brazilian program which was instituted to support this phased project.

    Full Text Available Dengue is the most important reemerging mosquito-borne viral disease worldwide. It is caused by any of four Dengue virus types or serotypes (DENV-1 to DENV-4 and is transmitted by mosquitoes from the genus Aedes. Ecological changes have favored the geographic expansion of the vector and, since the dengue pandemic in the Asian and Pacific regions, the infection became widely distributed worldwide, reaching Brazil in 1845. The incidence of dengue in Brazil has been frequently high, and the number of cases in the country has at some point in time represented up to 60% of the dengue reported cases worldwide. This review addresses vector distribution, dengue outbreaks, circulating serotypes and genotypes, and prevention approaches being utilized in Brazil.

In this paper we examine the intergroup intermarriage in Brazil in the context of changing urbanization and education. While intergroup marriage has been intensively examined in the United States, the topic has received less attention in Brazil. We use census data from 1991 and 2000, and national survey data from 2001 and 2008 to examine factors predicting intergroup marriage and the trends in intergroup marriage in Brazil. The results show higher rates of intermarriage in urban than in rural areas. Intermarriage is less common among the most educated people. While the rates of intermarriage are increasing substantially, the rates of change are diffuse across urban and rural areas, regions and education groups.

    Full Text Available Brazil faces numerous environmental challenges despite having many laws and policies in place. The implementation process of such laws and policies does not exist a majority of the time, affecting the quality of environmental governance in the country. Within the urban planning context, the City Statute law enacted in 2001 included the environmental dimension of urbanization; however, the wording of this inclusion was vague and broad. For instance, two environmental assessment planning tools of the law are not mandatory at the federal level and are without a defined scope. In this Exploration, a new framework focusing on the environmental dimension of urbanization is proposed. These two planning tools can be developed using the framework, which is based on the concept of carrying capacity and geographical information systems; it includes a combination of participatory mapping (i.e., increasing knowledge and tactical urbanism (i.e., increasing awareness to enhance public participation, targeting low-income populations. This combination was chosen because by increasing the knowledge and awareness of the poor who will participate in environmental-related projects, it will empower and allow them to exert their influence as citizens more fully. Resumen: Un marco para la planificación ambiental urbana en Brasil Resumen: Brasil afronta numerosos retos ambientales a pesar de contar con muchas leyes y políticas.

    The construction of hydropower plants unquestionably impacts the environment and communities. But countries such as Brazil have been able to build up a sophisticated socio-environmental legislation and institutions as well as a democratic and participative licensing process to protect the nature and the population affected. In some cases, plants greatly contribute towards the creation of local welfare to the population as well as good environmental practices. As a good example of best practices on socio-environmental standards, we will analyze Jirau Hydropower Project, currently under construction on the Madeira River, north of Brazil.

It confirms that, in Brazil, the mutual credit unions, besides being presented as one of the viable options within the financial system, are also seen as an alternative by which some sectors of society promote the humanization of the financial system by offering credit and return on capital with fairer interest rates.

    Full Text Available This article analyzes the differences in inter-generational social mobility and schooling between white, brown, and black men in Brazil. The main objective is to analyze inequality of opportunities for mobility and educational transitions. The results indicate that for individuals from lower social origins, inequality of opportunities is significantly marked by racial differences, and that for persons originating in the upper classes, racial inequality influences the odds of social mobility. The results suggest that theories of stratification by race and class in Brazil should be rethought, taking into account the observed interactions between race and class.

    Full Text Available Grapevine plants have been grown in different tropical regions of Brazil. In the state of Roraima, this culture was introduced commercially in 2005 in Boa Vista. Unlike temperate regions, tropical regions present thermal conditions for grape production throughout the year. To evaluate the climatic characteristics on different periods of the year, it can be used different indices. The objective of this study was to characterize climate suitability of Boa Vista, Roraima, Brazil, for grapevine cultivation at different months of the year. For climate classification it was used the Geoviticulture Multicriteria Climatic Classification System (CCM, which is composed by three indices: Heliothermal (IH, Cool Night (IF, and Drought (IS. It was also used the Zuluaga Index (IZ, to assess the risk of incidence of fungal diseases on the vine, especially in relation to the incidence of downy mildew (Plasmopara viticola, one of the main grapevine diseases in humid regions. Based on the evaluated indices, it was found that the most favorable period for grape production goes from October to March because of the lower values of rainfall. During the other months, it can be employed branch pruning without fruit production, as occurs in other tropical locations of Brazil. =A videira tem sido cultivada em diferentes regiões tropicais do Brasil. No estado de Roraima, ela foi implantada comercialmente em 2005 em Boa Vista. Ao contrário das regiões de clima temperado, as regiões tropicais apresentam condições térmicas para a produção de uvas durante o ano inteiro. Para se avaliar as características climáticas dos diferentes períodos do ano pode-se recorrer a diversos índices. Objetivou-se, com o presente trabalho, avaliar a aptidão climática de Boa Vista, Roraima, para o cultivo da videira, considerando-se diferentes períodos de produção ao longo do ano.

  9. Brazils Role in environmental governance: Analysis of possibilities for increased Brazil-Norway cooperation

    Valberg, Anna Helene

    2011-07-01

    This report examines the role played by Brazil in connection with certain international negotiations, such as the climate negotiations and the CBD. It identifies the driving factors that have influenced environmental politics and standards in Brazil, and take note of conflicts that must be discussed when Norway is seeking expanded cooperation with Brazil. In line with the mandate, FNI identifies areas of particular interest for further collaboration between the two countries, and recommend directions for supplementary Norwegian policy-making in light of a broadened scope for Norway-Brazil interaction. In recent years, the Norwegian government has initiated an extensive process aimed at reducing emissions from deforestation and forest degradation (REDD). This is the most obvious shared environmental scope between Norway and Brazil. However, given the large body of literature that already exists on this field, this report will concentrate instead on issues more on the outskirts of the REDD discourse, such as biodiversity conservation, biofuel efficiency and challenges concerning hydropower, all of which threaten to impact negatively on the Amazonian areas. In our recommendations, we cite tangible examples to illustrate issues where we believe lessons learnt in Norway may have applicability to Brazil.(auth)

  10. Brazil: the children of the day after.

    O'connor, G

    1993-01-01

    35 million people in Brazil live in starvation and absolute poverty. Many endemic diseases plague the country. Adding to Brazil's woes, however, AIDS has already affected more than 600,000 people domestically. As adults with children die premature deaths due to AIDS, their children become orphans. Government organizations have remained passive on the question of what to do with this growing number of children without families. No serious and complete studies exist on the subject of AIDS orphans in Brazil, so efforts on their behalf have been implemented mainly at the local level. Some orphans have been taken in by their grandparents, but these caretakers have only meager resources and few years of life remaining. The few private orphanages will not expand, adoption is complicated and tedious, state homes are not recommended, and nongovernmental organization (NGO) initiatives are inadequate. A campaign has therefore been launched to get sponsors to provide monthly economic aid to maintain orphans taken in by their close relatives. The author believes that it is up to NGOs to stimulate collective solidarity to support Brazil's growing number of orphans.

    2011-07-01

    Full Text Available Abstract Ancient connections between animals and human are seen in cultures throughout the world in multiple forms of interaction with the local fauna that form the core of Ethnozoology. Historically, ethnozoological publications grew out of studies undertaken in academic areas such as zoology, human ecology, sociology and anthropology - reflecting the interdisciplinary character of this discipline. The rich fauna and cultural diversity found in Brazil, with many different species of animals being used for an extremely wide diversity of purposes by Amerindian societies (as well as the descendents of the original European colonists and African slaves, presents an excellent backdrop for examining the relationships that exist between humans and other animals. This work presents a historical view of ethnozoological research in Brazil and examines its evolution, tendencies, and future perspectives. In summary, literature researches indicated that ethnozoology experienced significant advances in recent years in Brazil, although from a qualitative point of view improvement is still needed in terms of methodological procedures, taxonomic precision, and the use of quantitative techniques. A wide range of methodologies and theories are available in different areas of learning that can be put to good use in ethnozoological approaches if the right questions are asked. The challenges to studying ethnozoology in Brazil are not insignificant, and the tendencies described in the present study may aid in defining research strategies that will maintain the quantitative growth observed in the recent years but likewise foster needed qualitative improvements.

    Full Text Available Fish consumption per capita in Brazil is relatively modest when compared to other animal proteins. This study analyses the influence of protein prices, other food prices and population income on the fish demand in Brazil. First, the problem of fish supply in Brazil is characterized. It is followed by reviews of the relevant economic theory and methods of Almost Ideal Demand System - AIDS and their elasticity calculations. A descriptive analysis of fish demand in Brazil using the microdata called "Pesquisa de Orçamento Familiar" (Familiar Budget Research - POF 2002-2003 is presented. Finally, demand functions and their elasticities are calculated for two different cases: one considering five groups of animal proteins (Chicken; Milk and Eggs; Fish; Processed Proteins and Red Meat and other with seven groups of food categories (Cereals; Vegetables and Fruits; Milky and Eggs; Oils and Condiments; Fish; Other processed foods; and Meats. The main results are: per capita consumption of fish (4.6 kg per inhabitant per year is low in Brazil because few households consume fish. When only households with fish consumption are considered, the per capita consumption would be higher: 27.2 kg per inhabitant per year. The fish consumption in the North-East Region is concentrated in the low-income class. In the Center-South Region, the fish consumption is lower and concentrated in the intermediate income classes. The main substitutes for fish are the processed proteins and not the traditional types of meat, such as chicken and red meat.

    In the coastal multilayer aquifer system of a highly urbanized southern city (Recife, Brazil), where groundwaters are affected by salinization, a multi-isotope approach (Sr, B, O, H) was used to investigate the sources and processes of salinization. The high diversity of the geological bodies, built since the Atlantic opening during the Cretaceous, highly constrains the heterogeneity of the groundwater chemistry, e.g. Sr isotope ratios, and needs to be integrated to explain the salinization processes and groundwater pathways. A paleoseawater intrusion, most probably the 120 ky B.P. Pleistocene marine transgression, and cationic exchange are clearly evidenced in the most salinized parts of the Cabo and Beberibe aquifers. All {sup 87}Sr/{sup 86}Sr values are above the past and present-day seawater signatures, meaning that the Sr isotopic signature is altered due to additional Sr inputs from dilution with different freshwaters, and water–rock interactions. Only the Cabo aquifer presents a well-delimitated area of Na-HCO{sub 3} water typical of a freshening process. The two deep aquifers also display a broad range of B concentrations and B isotope ratios with values among the highest known to date (63–68.5‰). This suggests multiple sources and processes affecting B behavior, among which mixing with saline water, B sorption on clays and mixing with wastewater. The highly fractionated B isotopic values were explained by infiltration of relatively salty water with B interacting with clays, pointing out the major role played by (palaeo)-channels for the deep Beberibe aquifer recharge. Based on an increase of salinity at the end of the dry season, a present-day seawater intrusion is identified in the surficial Boa Viagem aquifer. Our conceptual model presents a comprehensive understanding of the major groundwater salinization pathways and processes, and should be of benefit for other southern Atlantic coastal aquifers to better address groundwater management issues

    Toxoplasmic retinochoroiditis appears to be more severe in Brazil, where it is a leading cause of blindness, than in Europe, but direct comparisons are lacking. Evidence is accumulating that more virulent genotypes of Toxoplasma gondii predominate in South America. We compared prospective cohorts of children with congenital toxoplasmosis identified by universal neonatal screening in Brazil and neonatal or prenatal screening in Europe between 1992 and 2003, using the same protocol in both continents. Three hundred and eleven (311) children had congenital toxoplasmosis: 30 in Brazil and 281 in Europe, where 71 were identified by neonatal screening. Median follow up was 4.1 years in Europe and 3.7 years in Brazil. Relatively more children had retinochoroiditis during the first year in Brazil than in Europe (15/30; 50% versus 29/281; 10%) and the risk of lesions by 4 years of age was much higher: the hazard ratio for Brazil versus Europe was 5.36 (95%CI: 3.17, 9.08). Children in Brazil had larger lesions, which were more likely to be multiple and to affect the posterior pole (pBrazil, visual impairment (congenitally infected children in Brazil compared with Europe. The marked differences in the frequency, size and multiplicity of retinochoroidal lesions may be due to infection with more virulent genotypes of the parasite that predominate in Brazil but are rarely found in Europe.

  14. Ehrlichiosis in Brazil Erliquiose no Brasil

    Full Text Available Ehrlichiosis is a disease caused by rickettsial organisms belonging to the genus Ehrlichia. In Brazil, molecular and serological studies have evaluated the occurrence of Ehrlichia species in dogs, cats, wild animals and humans. Ehrlichia canis is the main species found in dogs in Brazil, although E. ewingii infection has been recently suspected in five dogs. Ehrlichia chaffeensis DNA has been detected and characterized in mash deer, whereas E. muris and E. ruminantium have not yet been identified in Brazil. Canine monocytic ehrlichiosis caused by E. canis appears to be highly endemic in several regions of Brazil, however prevalence data are not available for several regions. Ehrlichia canis DNA also has been detected and molecularly characterized in three domestic cats, and antibodies against E. canis were detected in free-ranging Neotropical felids. There is serological evidence suggesting the occurrence of human ehrlichiosis in Brazil but its etiologic agent has not yet been established. Improved molecular diagnostic resources for laboratory testing will allow better identification and characterization of ehrlichial organisms associated with human ehrlichiosis in Brazil.Erliquiose é uma doença causada por rickettsias pertencentes ao gênero Ehrlichia. No Brasil, estudos sorológicos e moleculares têm avaliado a ocorrência de espécies de Ehrlichia em cães, gatos, animais selvagens e seres humanos. Ehrlichia canis é a principal espécie em cães no Brasil, embora a infecção por E. ewingii tenha, recentemente, despertado suspeita em cinco cães. O DNA de E. chaffeensis foi detectado e caracterizado em cervo-do-pantanal, enquanto que E. muris e E. ruminantium ainda não foram identificadas no Brasil. A erliquiose monocítica canina causada pela E. canis parece ser altamente endêmica em muitas regiões do Brasil, embora dados de prevalência não estejam disponíveis em muitas delas. O DNA de E. canis também foi detectado e caracterizado

    Marcel Teixeira

    Full Text Available Coccidiosis is a disease that limits the production and marketing of gallinaceous birds in North America, especially quails, pheasants and chukar partridges. Virtually no research has been conducted in South America on the causative agents of diseases among these birds, including coccidia. The aim of this work was to make first observations on Eimeria spp. in the chukar partridge Alectoris chukar and the grey quail Coturnix coturnix, which are reared for meat in Brazil. Fecal and tissue samples were collected from commercial farms and were examined for oocysts, gross and microscopic lesions or endogenous stages. From this examination, it was found that partridges raised in Brazil did not have any visible infection. However, grey quails presented mild infection and two Eimeria species that had previously been described in other birds were identified.

    This article analyzes the current regulatory framework for biobanking, genomic research, and protection of privacy in Brazil. It is divided in four parts. The first describes the biobanking context in Brazil and its evolution in recent years. In the second, the entire regulatory framework on biobanking and genomic research is analyzed. The third part focuses on the critical evaluation of this regulatory framework, specifically on some major ethical dilemmas in biobanking. The fourth part describes the characteristics of the Brazilian biobanking and human research governance system, known as the CEP/CONEP system. Finally, the conclusion summarizes the information in the article and its contribution to the study of the biobanking ethical challenges, especially the protection of privacy. It is highlighted that biobanking regulatory harmonization among countries is necessary, since it increases scientific possibilities that can come from broader cooperation among biobanks and several research centers on the national and international levels. © 2015 American Society of Law, Medicine & Ethics, Inc.

    Full Text Available Norovirus (NoV infections are a major cause of acute gastroenteritis outbreaks around the world. In Brazil, the surveillance system for acute diarrhoea does not include the diagnosis of NoV, precluding the ability to assess its impact on public health. The present study assessed the circulation of NoV genotypes in different Brazilian states by partial nucleotide sequencing analysis of the genomic region coding for the major capsid viral protein. NoV genogroup II genotype 4 (GII.4 was the prevalent (78% followed by GII.6, GII.7, GII.12, GII.16 and GII.17, demonstrating the great diversity of NoV genotypes circulating in Brazil. Thus, this paper highlights the importance of a virological surveillance system to detect and characterize emerging strains of NoV and their spreading potential.

    Although the number of confirmed cases of spotted fever has been declining in Brazil since 2005, the mortality rate (20% to 30%) is still high in comparison to other countries. This high mortality rate is closely related to the difficulty in making the diagnosis and starting the correct treatment. Only two groups of antibiotics have proven clinical effectiveness against spotted fever: chloramphenicol and tetracyclines. Until recently, the use of tetracyclines was restricted to adults because of the associated bone and tooth changes in children. Recently, however, the American Academy of Pediatrics and various researchers have recommended the use of doxycycline in children. In more severe cases, chloramphenicol injections are often preferred in Brazil because of the lack of experience with injectable tetracycline. Since early diagnosis and the adequate drug treatment are key to a good prognosis, health care professionals must be better prepared to recognize and treat spotted fever.

    2010-03-01

    The article explores the links between the controversial apprehension of contaminated apples in southern Brazil in 1989 and the reactions of the apple industry to press reports on the use of pesticides in Brazilian orchards. The issue is framed within a broader analysis of the notions of toxicity and 'danger' surrounding the consumption of healthier food and the idea of 'food security,' notions that have begun taking hold in public and private life. It is argued that apple growers' responses to the problem can be better understood through a historical reading of the interactions between the biology of the apple tree, the agroecology of this monoculture, and the structures, actors, and discourses of the human and non-human groups in Brazil's apple-producing region.

    To determine the most common approach to repair the anophthalmic socket in Brazil, and to compare the data with the trends in other countries. Exploratory study using electronic questionnaire sent by Internet to ophthalmologists members of the Brazilian Orbit and Oculoplastic Society (SBCPO). The received answers were analyzed by adhesion analysis, using Chi-square test. We received 75 answered questionnaires. Fifty-three per cent of the respondents frequently treat anophthalmic socket and use the 18 mm diameter polymethylmethacrylate sphere in the majority of the surgeries, mainly covered by sclera (92%). Only seven interviewees had used integrated implants with pegging procedure. Eighty-two per cent of the ophthalmologists use the dermolipid graft to reconstruct the anophthalmic socket. They also follow the patients bi-annually. The treatment of anophthalmic socket in Brazil generally involve polymethylmethacrylate sphere with 18 mm diameter. Pegging procedure is uncommon between us.

  5. Inequality and School reform in Bahia, Brazil

    Science.gov (United States)

    Reiter, Bernd

    2009-07-01

    This article compares public and community schools in Salvador, the state capital of Bahia, Brazil. Based on quantitative data analysis and qualitative research conducted on-site during three research trips in 2001, 2003 and 2005, the author finds that Brazil's extreme inequality and the associated concentration of state power in a few hands stand in the way of an effective reform. In 1999, the state of Bahia started to reform its basic education cycle, but the author's research shows that Bahian elites use access to basic education to defend their inherited privilege. The analysis of community schools further demonstrates that inequality also blocks effective community and parental involvement in school management, as schools tend to distance themselves from neighbourhoods portrayed as poor and black, and thus "dangerous".

Esse valor de salinidade e um pouco maior do que o índice termohalino modificado da ACAS (36,20 ‰ e pode ser usado com vantagem nos cálculos volumétricos na área. As expressões polinomiais da curva T-S, cujos coeficientes foram determinados pelo método dos mínimos quadrados, foram usadas em aplicações práticas.

The water sampling was carried out with standard methods in a network of hydrographie stations worked in five-time intervals (5-10 days, from January 1970 through February 1971. The classification review of the water masses used under regional conditions confirm that the Subtropical-Deep (STDW, Subtropical (STW and South Atlantic Central (SACW Water Masses are different nomenclature for the same water mass; the latter is suggested to indicate a water mass with a thermohaline index given by (20.0 ºC; 36.36 ‰, observed underneath the Tropical Water Mass. This salinity value is slightly higher than the modified thermohaline index of the SACW (36.20 ‰, and can be used with great simplification in volumetric studies in the area. Polynomial expressions of the mean T-S curve, whose coefficients were computed with the least squares method, were given for practical applications. From these applications, alternative methods for the determination of the thermohaline derivative and constant density ratio (Rρ = αdT/βdS were obtained.

    As the responsibility and demand on health care grows and resources do not increase at the same pace, the healthcare system has been forced to reconsider the benefits and costs of their actions, to ensure a rational and effective decision-making process regarding the adoption of interventions and allocation of resources. Cost-effectiveness (CE) studies represent one of the basic tools to achieve this goal. To present the current state of Health Technology Assessment (HTA) and health economics in mental health in Brazil and its importance to the decision-making process. Descriptive paper on HTA and health economics in Brazil. Databases from government and universities as well as some scientific databases to assess the information are presented. Economic analysis to evaluate interventions in mental health care is a relatively recent addition to the field of health economics; in Brazil, it is also considered a topic within Epidemiology research area. There have been an increased number of studies developed in high-income countries. However, there are fewer CE studies in low- and middle-income ones. Psychiatric disorders represent a significant burden in developing countries, where resources devoted to health care are even scarcer.

    2017-01-01

    The aim of the present work is to address the description of hyperinflation regimens in economy. The spirals of hyperinflation developed in Brazil, Israel, and Nicaragua are revisited. This new analysis of data indicates that the episodes occurred in Brazil and Nicaragua can be understood within the frame of the model available in the literature, which is based on a nonlinear feedback (NLF) characterized by an exponent β > 0. In the NLF model the accumulated consumer price index carries a finite time singularity of the type 1 /(tc - t) (1 - β) / β determining a critical time tc at which the economy would crash. It is shown that in the case of Brazil the entire episode cannot be described with a unique set of parameters because the time series was strongly affected by a change of policy. This fact gives support to the ;so called; Lucas critique, who stated that model's parameters usually change once policy changes. On the other hand, such a model is not able to provide any tc in the case of the weaker hyperinflation occurred in Israel. It is shown that in this case the fit of data yields β → 0. This limit leads to the linear feedback formulation which does not predict any tc. An extension for the NLF model is suggested.

    The constitution of Brazil directs that the country's health system, the Unified Health System (Sistema Unico de Saúde), be politically and administratively decentralized. Nevertheless, handing over competencies, responsibilities, and resources to subnational levels, especially to municipal governments, has been a slow process, lasting almost two decades. Advances have been brought about by the Unified Health System, which, from a analytical perspective, is a public and universal system. Despite that, the decentralization process needs to overcome norms that keep all levels of management dependent on Brazil's federal Government. The subnational levels have consistently faced difficulties in performing their macromanagement functions with autonomy, especially when it comes to financing and to the establishment or organization of health care networks. Boldness and responsibility will be needed to prevent Brazil's health decentralization process from leading to fragmentation. New political agreements between different levels of government, with a reassignment of responsibilities and the enhancement of a culture of technical cooperation, are fundamental requisites to making the Unified Health System have a health policy that is truly public and universal.

  2. Brazil's Amazonian dams: Ecological and socioeconomic impacts

    Fearnside, P. M.

    2016-12-01

    Brazil's 2015-2024 Energy Expansion Plan calls for 11 hydroelectric dams with installed capacity ≥ 30 MW in the country's Amazon region. Dozens of other large dams are planned beyond this time horizon, and dams with consumers. Population displacement is a major impact; for example, the Marabá Dam would displace 40,000 people, mostly traditional riverside dwellers (ribeirinhos). Various dams impact indigenous peoples, such as the Xingu River dams (beginning with Belo Monte) and the São Luiz do Tapajós and Chacorão Dams on the Tapajós River. Brazil has many energy options other than dams. Much energy use has little benefit for the country, such as exporting aluminum. Electric showerheads use 5% of the country's power. Losses in transmission lines (20%) are far above global averages and can be expected to increase as Amazonian hydroelectric dams far from consumer centers come on line. Brazil has tremendous wind and solar potential, but these do not have the same priority as dams. At the root of many questionable policies is a decision-making process in need of reform.

    Brazil faces an enormous challenge to implement its revised Forest Code. Despite big losses for the environment, the law introduces new mechanisms to facilitate compliance and foster payment for ecosystem services (PES). The most promising of these is a market for trading forest certificates (CRAs) that allows landowners to offset their restoration obligations by paying for maintaining native vegetation elsewhere. We analyzed the economic potential for the emerging CRA market in Brazil and its implications for PES programs. Results indicate a potential market for trading 4.2 Mha of CRAs with a gross value of US$ 9.2±2.4 billion, with main regional markets forming in the states of Mato Grosso and São Paulo. This would be the largest market for trading forests in the world. Overall, the potential supply of CRAs in Brazilian states exceeds demand, creating an opportunity for additional PES programs to use the CRA market. This expanded market could provide not only monetary incentives to conserve native vegetation, but also environmental co-benefits by fostering PES programs focused on biodiversity, water conservation, and climate regulation. Effective implementation of the Forest Code will be vital to the success of this market and this hurdle brings uncertainty into the market. Long-term commitment, both within Brazil and abroad, will be essential to overcome the many challenges ahead.

  4. Present situation of refractories in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    Bittencourt, P. (Magnesita S.A., (Brazil))

    1992-11-10

    This paper outlines the present situation of refractories in Brazil, particularly the use of refractories in the steel industry which is one of the major industries in this country. Brazil is the 8th largest steel producer in the world, and about 64% of all the production is exported. Because of increasing competitions in the world market, high-level production techniques are required, and active improvements of refractories are also being carried out. The specific consumption of refractories in 1 ton of steel has gradually decreased to produce high-quality refractories. In Brazil, 95% of all demand except for special items such as submerged nozzles and blast furnace carbon blocks can be provided domestically. It is characteristic that raw materials for refractories, such as magnesite, bauxite, and graphite can also be self-supporting. Compositions and physical properties of typical refractories used for various purposes in iron and steel manufactures including blast furnaces, torpedo cars, BOF converters, electric are furnaces, and electric arc ladles are described, and the direction toward their conversion into new materials is shown. Moreover, the trends of refractories for the cement industry and for nonferrous metals such as aluminum are introduced. 6 figs., 15 tabs.

    A Christian theology is important to bioethics in Brazil not only because Brazil is a country of strong Christian traditions, but also because of its theological method and because of many practices in their Christian communities. In fact, the interaction within practice and theory is a big point of its methodology. A heritage of a long history of colonialism in South America comes to our times as enormous social inequalities. In such a context, the silent cry of poor people is heard as a question of coherence to the Christian faith and to the neighbor love. Through a constant dialog with human sciences, the method of theology, known as liberation theology, seeks the roots of social inequalities and the alternatives to a movement of spiritual and social liberation. In touch with the modern bioethics, this theology has strongly contributed to understand all the questions of bioethics in the frame of social structures and systems. On the other hand, many actual practices of the Catholic Church in Brazil with popular impact, like its annual Fraternity Campaign, develop social themes and problems that are also big concerns of bioethics. In this article we try to expose some aspects of this dialog, where theology has a well considered contribution to Brazilian bioethics, at the same time his religious discourse is open to interact with a lay discourse.

  9. Access to Environmental Justice in Brazil

    Full Text Available Abstract: This article aims to show how the equal access to environmental justice occurs in Brazil, even with litigants in inequality, with discrimination on the environmental matter, problems with interpretation of the law and few jurisprudence and information. The increase in the access to justice in Brazil is evident, including the environmental area. As access to justice, we must understand the two basic purposes of the legal system: that the system has to be equally accessible to everybody and that it produces individual and socially fair results, not just the simplistic conceptualization of the number of lawsuits. True access to justice is achieved once the rights of the population are effectively guaranteed. The amount of environmental lawsuits has been increasing each year, mainly after the Brazilian Federal Constitution of 1988, considering that article 225 provided the need for an ecologically balanced environment for present and future generations, besides determining that the government and the community have the duty to preserve it. In addition, the problems are not being adequately resolved at the administrative level. Access to environmental justice should be understood as access to the law, a fair, well-known and effective legal order, with access to the courts, to alternative mechanisms (especially preventive ones and the population materially and psychologically conscious to exercise their rights, by overcoming objective and subjective barriers. For this access, appropriate procedural instruments are necessary to the collective conflicts and the environmental protection, in order to facilitate the protection of the environment in courts, and to overcome barriers to the access to justice in this matter. In Brazil, some procedural instruments have come as a way to guarantee access to environmental justice. They are, mainly: “popular action” and “public civil action”. Both have a specific provision for admission with

    Full Text Available This article examines the relationship between political culture and social capital in Brazil. It emphasizes the importance of constructing a political system founded in the interpersonal or reciprocal trust, as well as the confidence in the political institutions. After examining the main controversies about the definition of social capital, this article defends the idea of reterritorializing this concept, giving a strategic value insofar as the instrumental dimension is concerned, which is, the empowerment of the citizens so as to help to construct and institutionalize a participant political culture. After examining surveys carried out in Porto Alegre, Brazil, the main conclusion is that the levels of social capital in this city, and probably extensive to the country, are very low compromising, in the short run, the possibility of gerating a critical and participative citizenship.El presente artículo examina la relación entre cultura política y capital social en Brasil. Se enfatiza la importancia de construir un sistema político fundamentado en la confianza recíproca o interpersonal así como la confianza con relación a las instituciones políticas. Después de examinar las controversias sobre la conceptualización de capital social, este trabajo defiende la idea de la reterritorialización de ese concepto, valorizando su dimensión instrumental, es decir, el empoderamiento de los ciudadanos objetivando el desarrollo e institucionalización de una cultura política participativa. Tras desarrollar un análisis de encuestas llevadas a cabo en Porto Alegre, Brasil, se llega a la conclusión de que los niveles de capital social en el país son muy bajos comprometiendo, a corto plazo la posibilidad de generar una ciudadanía crítica y participativa.

    Social participation in the health system constitutes one of the basic principles of Brazilian health sector reform. This paper analyses the concepts held by different groups of stakeholders with respect to social participation in health and identifies their opinions on hindering and enabling factors for this participation. A qualitative study was conducted using individual interviews (II) and focus groups (FG) with different groups of stakeholders: 135 users (II, GF), 14 community leaders (II, GF), 12 Municipal Health Council (MHC) members (II), 8 policymakers and (II) 37 health personnel (II, GF) were interviewed. A narrative content analysis of the results was conducted. Two municipalities in North-eastern Brazil, Cabo de Santo Agostinho and Camaragibe, made up the area of study. In all groups, a distinction between individual and group participation emerged and reached different levels of elaboration. Many informants' ideas described also their own ways of action. Individual participation concepts and the utilization of health services were predominant among users. Population and institutional factors were identified as obstacles to participation: users and community leaders referred both type of factors, while the health personnel and MHC members put more emphasis on the former. Some informants among the health personnel did not identify any barriers. Policymakers emphasised the lack of political will. The enabling factors mentioned reflected the same logic. Concepts and perceived hindering factors to participation which were described appear to show different ways of interaction among the diverse stakeholders and the health services. The results point towards a limited effect of the health policy on social participation. Elements that could contribute to an improvement are identified.

    1996-04-01

    More than 95% of total energy produced in Brazil comes from highly efficient hydroelectric power plants but, faced with a serious shortage of energy after the year 2000, the country is now considering wind energy as one of the basic alternatives for energy supply. It is suggested that biomass, wind energy and biogas may be included in a future supply policy for the north-east region of the land. The structure of, the privatisation, legislation and the tariff system within the Brazilian power sector are described in addition to the present situation regarding wind energy in the country, including current and coming projects in this field, the excellent wind conditions in Northeastern Brazil and investment possibilities. The political activities in this field of the Danish Folkecenter for Renewable Energy are noted and future developments in Brazil are discussed. It is concluded that there are good prospects for Danish windmill technology on the Brazilian market. Wind measurement programs are presently being carried out in various areas of the country, though a number of impediments to the development of wind energy in Brazil remain. (AB)

    From a conservationist perspective, seahorses are threatened fishes. Concomitantly, from a socioeconomic perspective, they represent a source of income to many fishing communities in developing countries. An integration between these two views requires, among other things, the recognition that seahorse fishers have knowledge and abilities that can assist the implementation of conservation strategies and of management plans for seahorses and their habitats. This paper documents the knowledge held by Brazilian fishers on the biology and ecology of the longsnout seahorse Hippocampus reidi. Its aims were to explore collaborative approaches to seahorse conservation and management in Brazil; to assess fishers' perception of seahorse biology and ecology, in the context evaluating potential management options; to increase fishers' involvement with seahorse conservation in Brazil. Data were obtained through questionnaires and interviews made during field surveys conducted in fishing villages located in the States of Piauí, Ceará, Paraíba, Maranhão, Pernambuco and Pará. We consider the following aspects as positive for the conservation of seahorses and their habitats in Brazil: fishers were willing to dialogue with researchers; although captures and/or trade of brooding seahorses occurred, most interviewees recognized the importance of reproduction to the maintenance of seahorses in the wild (and therefore of their source of income), and expressed concern over population declines; fishers associated the presence of a ventral pouch with reproduction in seahorses (regardless of them knowing which sex bears the pouch), and this may facilitate the construction of collaborative management options designed to eliminate captures of brooding specimens; fishers recognized microhabitats of importance to the maintenance of seahorse wild populations; fishers who kept seahorses in captivity tended to recognize the condtions as poor, and as being a cause of seahorse mortality.

    Full Text Available Because of its high interest rates, Brazil attracts more and more speculative capital flows, called "hot money", under the form of foreign loans, direct or portfolio investments. Actually, the country is directly involved in a carry-trade strategy that tends to appreciate the real, what penalizes the Brazilian exportations of manufactured products. Moreover, capital inflows are extremely volatile, and their departure, causing a fall in loans granted to the Brazilian private banks, could provoke a dangerous burst of the speculative bubble they have contributed to form in the Brazilian real estate sector.

We will thus understand the role of subnational media in sustaining pluralism and in providing independent sources of information, two critical dimensions of democracy.

  14. Catholic populism and education in Brazil

    Paiva, Vanilda

    1995-05-01

    Education in Brazil has been profoundly affected by populism, a movement which extols the virtue of the oppressed classes and opposes the traditional teacherstudent relationship. This movement has antecedents in nineteenth-century Russian writers such as Herzen and Bakunin. The author shows how populist ideas, often merging with Marxism, were adopted by many Brazilian Catholics from the 1950s onwards, under the influence of Vieira Pinto, Paulo Freire and others. In the realm of education this often led to an extreme form of anti-authoritarianism. While not denying certain positive aspects of this movement, the author argues that its position is fundamentally self-contradictory.

    Due to negative experiences in the past, biogas technology could not establish itself in Brazil. Currently though, there is a revival of agricultural biogas plants there. Biogas production from animal residues is especially suited for the southern regions, where swine and poultry farms are concentrated. Generally the Brazilian plants are small and simple units, which cannot be compared to those in Germany. Vinasse, a fluid residue from alcohol production with high potassium content, is generally used as fertilizer on sugar cane fields. Using vinasse as a substrate for biogas production would be very recommendable, but is seldom done due to lacking general political conditions and technology. (orig.)

    From Albian to end Cretaceous times, the inboard part of the Santos Basin in Brazil was affected by extension as salt flowed basinwards under the effect of gravity. Salt rollers, flip-flop salt diapirs and the famous Albian Gap were all formed by this process. Outboard of these extensional structures, contraction was taken up in a wide zone of thickened salt where salt collected. The overburden was carried on top of the salt as it flowed down-dip, with up to 40 km of translation recorded in Albian strata. (author)

    2007-08-01

    This paper discusses the Brazilian Supreme Court ruling on the case of anencephaly. In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non-viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral status of the fetus, the cornerstone thesis of the Catholic Church.

    To analyze the compliance of drug advertisements with regulations in Brazil, subject to Resolution RDC No. 102/2000 since 2000, which abides by the WHO's (World Health Organization) Ethical Criteria for Medicinal Drug Promotion, published in 1988. Drug advertisements running within the period of October 2002 to October 2003 were collected and recorded. Media sources included various AM and FM radio stations, television channels, newspapers, and magazines, as well as printed material distributed in doctors' offices, hospitals, drugstores, conferences, billboards, and bus doors. All sources were located in Curitiba City, Brazil, and its surrounding area. Advertisement content was analyzed according to a conformity checklist prepared based on the legal requirements of RDC No. 102/00. A total of 827 advertisements for 517 different products, 83.91% regularly registered as medicinal drugs and 16.09% unregistered products that should be registered according to the Brazilian regulations, were recorded and collected. Approximately 74.73% of the advertisements did not comply with regulations; on average, such advertisements had 4.6 infractions each. The results of this research suggest that RDC No. 102/00 is not followed, which strengthens the need to adopt new forms of regulation to prohibit excesses of the pharmaceutical industry and to protect the population from abusive and misleading drug advertising.

  20. Coccidioidomycosis in Brazil. A case report

    Directory of Open Access Journals (Sweden)

    1997-01-01

    Full Text Available Coccidioidomycosis is an endemic infection with a relatively limited geographic distribution: Mexico, Guatemala, Honduras, Colombia, Venezuela, Bolivia, Paraguai, Argentina and the southwest of the United States. In these countries, the endemic area is restricted to the semiarid desert like regions which are similar to the northeast of Brazil. Case report: The patient is a 32 year-old male, born in the state of Bahia (Northeast of Brazil and has been living in São Paulo (Southeast for 6 years. He was admitted at Hospital das Clínicas, at the Department of Pneumology in October 1996, with a 6 month history of progressive and productive cough, fever, malaise, chills, loss of weight, weakness and arthralgia in the small joints. Chest x-rays and computerized tomography disclosed an interstitial reticulonodular infiltrate with a cavity in the right upper lobe. The standard potassium hydroxide preparation of sputum and broncoalveolar lavage demonstrated the characteristic thickened wall spherules in various stages of development. Sabouraud dextrose agar, at 25° C and 30° C showed growth of white and cottony aerial micelium. The microscopic morphology disclosed branched hyphae characterized by thick walled, barrel shaped arthroconidia alternated with empty cells. The sorological studies with positive double immunodiffusion test, and also positive complement fixation test in 1/128 dilution confirmed the diagnosis. The patient has been treated with ketoconazole and presents a favorable clinical and radiological evolution

    Bullying has been the subject of worldwide study for over four decades and is widely reported by social media. Despite this, the issue is a relatively new area of research in Brazil. This study analyzes academic literature addressing bullying produced in Brazil focusing on aspects that characterize this issue as a subtype of violence: gender differences, factors associated with bullying, consequences, and possible intervention and prevention approaches. The guiding question of this study was: what have Brazilian researchers produced regarding bullying among adolescents? The results show that over half of the studies used quantitative approaches, principally cross-sectional methods and questionnaires, and focused on determining the prevalence of and factors associated with bullying. The findings showed a high prevalence of bullying among Brazilian adolescents, an association between risk behavior and bullying, serious consequences for the mental health of young people, lack of awareness and understanding among adolescents about bullying and its consequences, and a lack of strategies to manage this type of aggression. There is a need for intervention studies, prevention and restorative practices that involve the community and can be applied to everyday life at school.

  2. Forensic entomology and main challenges in Brazil.

    Gomes, Leonardo; Von Zuben, Cláudio J

    2006-01-01

    Apart from an early case report from China (13th century), the first observations on insects and other arthropods as forensic indicators were documented in Germany and France during mass exhumations in the 1880s by Reinhard, who is considered a co-founder of the discipline. After the French publication of Mégnin's popular book on the applied aspects of forensic entomology, the concept quickly spread to Canada and United States. At that time, researchers recognized that the lack of systematic observations of insects of forensic importance jeopardized their use as indicators of postmortem interval. General advances in insect taxonomy and ecology helped to fill this gap over the following decades. After World Wars, few forensic entomology cases were reported in the scientific literature. From 1960s to the 1980s, Leclercq and Nuorteva were primarily responsible for maintaining the method in Central Europe, reporting isolated cases. Since then, basic research in the USA, Russia and Canada opened the way to the routine use of Entomology in forensic investigations. Identifications of insects associated with human cadavers are relatively few in the literature of the Neotropical region and have received little attention in Brazil. This article brings an overview of historic developments in this field, the recent studies and the main problems and challenges in South America and mainly in Brazil.

    Hail is considered to be among the most complex extreme weather phenomena of the atmosphere. Every year, notably in the southern Brazilian States, destructive hailstorms result in serious economic losses and cause a great social impact destroying crops, homes, medical facilities and schools. The aim of this study is to document the spatial, annual, and diurnal variation in destructive hailstorm frequency during a 22 year period from 1991 to 2012 in Brazil. The analysis is based on a collection of reports released by the Brazilian National Civil Protection Secretariat - SEDEC. Based on reports of emergency assistance given to the population affected by a disaster, the information discussed in this work is assumed as representative only of destructive hailstorms. The analysis reveals a large spatial variability, with the majority of hailstorm occurrences distributed in the three southernmost Brazilian States. Within those states, the number of hail reports was observed to increase with increasing population density in rural areas. Hailstorms were reported most often in the late afternoon and evening of the winter/spring transition, in agreement with a few other areas in the subtropics with available studies, but different from the majority of studies for temperate zones, which suggest spring/summer as the hail season. Although the results show some discrepancies compared to satellite hail signatures, the findings of this work confirm that southern Brazil is a region prone to the development of strong convective storms, with high annual numbers of destructive hail events.

  5. The changing face of autism in Brazil.

    2015-06-01

    At the end of 2012, after intensive lobbying by parent activist associations, a federal law recognized autism as a "disability for all legal purposes" in Brazil. Defining autism as a disability was more than a change of legal status to guarantee social benefits. It was also a political maneuver, orchestrated by parent associations, aimed to take the responsibility for treatment away from the public mental health network of services. This article examines the controversies that have set parent associations in direct antagonism with mental health professionals in the public health system. We draw from ethnographic data and theoretical discussions in the field of disability studies to situate these controversies within the context of a larger debate on the relationship between health, rights, and citizenship. We found similarities between the ethical and political goals of parent activists and mental health professionals in Brazil, but we argue that the main cause of dissent is the role that each of these social actors assigns to identity politics in their clinical and political projects.

  6. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

    Full Text Available Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and Pacific oceans and in the Caribbean and Mediterranean seas. Brazilian sponges remain understudied concerning antifouling activities. Only two scientific articles reported this activity in sponges of Brazil. The objective of this study was to test crude extracts of twelve species of sponges from Brazil against the attachment of the mussel Perna perna through laboratorial assays, and highlight promising species for future studies. The species Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra, and Tethya maza were frozen and freeze-dried before extraction with acetone or dichloromethane. The crude extract of four species significantly inhibited the attachment of byssus: Tethya rubra (p = 0.0009, Tethya maza (p = 0.0039, Petromica citrina (p = 0.0277, and Hymeniacidon heliophila (p = 0.00003. These species, specially, should be the target of future studies to detail the substances involved in the ability antifouling well as to define its amplitude of action.

    Thalidomide causes congenital defects in children, such as limb reduction defects. Currently, it is used for a few indications; in Brazil, where leprosy is endemic, thalidomide is used for the treatment of erythema nodosum leprosum, and recent cases of thalidomide embryopathy have been reported. We analyzed the frequency of births with phenotypes consistent with thalidomide embryopathy (TEP) and correlated this with the distribution of thalidomide and the prevalence of leprosy between 2005 and 2010 in Brazil. A total of 5,889,210 thalidomide tablets were distributed; the prevalence of limb reduction defects was 1.60 (CI95%: 1.54-1.66) and TEP was 0.11 (CI95%: 0.10-0.13) per 10,000 births. Poisson regression showed an increase in cases of TEP and limb reduction defects per 100,000 tablets dispensed. Clusters and geographical isolates were identified in several regions. There is a correlation between thalidomide and TEP showing that thalidomide embryopathy should be monitored in countries where this medication is available. Copyright © 2015 Elsevier Inc.

    Research on food irradiation in Brazil started in 1968 at the Center of Nuclear Energy for Agriculture (CENA), Piracicaba, Sao Paulo. At the Institute of Nuclear and Energy Research (IPEN-CNEN/SP), Sao Paulo, Sao Paulo, research on detection of irradiated foods is in progress. In 1973, the Brazilian government established a regulation about food irradiation. Nowadays, the products authorized to be irradiated are: rice, poultry, fish and fish products, potatoes, onions, avocados, persimmons, pineapples, wheat flour, maize, beans, spices, tomatoes, guavas, oranges, lemons, strawberries, mangoes, melons and papayas. The other recommended products to be approved in the future are: acerolas, apples, beans (dose > 1 kGy), beef, blueberries, cherries, cheeses, coffee, figs, fresh guaranas, garlics, grapefruits, grapes, mushrooms, nuts and pork. Today, there is only one commercial facility for irradiation services in the country, the Empresa Brasileira de Radiacoes Ltda. (EMBRARAD). This company operates a Nordion JS-7500 irradiator, with a present activity of about 1,000 kCi, designed for sterilizing medical devices. It also irradiates spices, dried foods, gemstones, cosmetics, wood and raw materials for pharmaceuticals. The plant operates 24 hours a day and the spices and dried foods represent 15% of the business. Powder of guarana seeds is irradiated also for exportation. There are two other commercial facilities for radiation sterilization in Brazil, operating exclusively for their own production. (J.P.N.)

    The subspecialty of pediatric allergy and immunology in Brazil is in its early years and progressing steadily. This review highlights the research developed in the past years aiming to show the characteristics of allergic and immunologic diseases in this vast country. Epidemiologic studies demonstrated the high prevalence of asthma in infants, children, and adolescents. Mortality rates and average annual variation of asthma hospitalization have reduced in all pediatric age groups. Indoor aeroallergen exposure is excessively high and contributes to the high rates of allergy sensitization. Prevalence of food allergy has increased to epidemic levels. Foods (35%), insect stings (30%), and drugs (23%) are the main etiological agents of anaphylaxis in children and adolescents. Molecular diagnosis of primary immunodeficiencies (PID) showed a high incidence of fungal infections including paracoccidioidomycosis in X-linked hyper-IgM syndrome, and the occurrence of BCG adverse reactions or other mycobacterial infections in patients with chronic granulomatous disease. Education in pediatric allergy and immunology is deficient for medical students, but residency programs are effective in training internists and pediatricians for the practice of allergy. The field of PID requires further training. Last, this review is a tribute to Prof. Dr. Charles Naspitz, one of the pioneers of our specialty in Brazil. © 2013 John Wiley & Sons A/S.

    2004-08-01

    An outbreak of cryptococcosis occurred in a breeding aviary in São Paulo, Brazil. Seven psittacine birds (of species Charmosyna papou, Lorius lory, Trichoglossus goldiei, Psittacula krameri and Psittacus erithacus) died of disseminated cryptococcosis. Incoordination, progressive paralysis and difficulty in flying were seen in five birds, whereas superficial lesions coincident with respiratory alterations were seen in two birds. Encapsulated yeasts suggestive of Cryptococcus sp. were seen in faecal smears stained with India ink in two cases. Histological examination of the birds showed cryptococcal cells in various tissues, including the beak, choana, sinus, lungs, air sacs, heart, liver, spleen, kidneys, intestines and central nervous system. High titres of cryptococcal antigen were observed in the serum of an affected bird. In this case, titres increased during treatment and the bird eventually died. Yeasts were isolated from the nasal mass, faeces and liver of one bird. Cryptococcus neoformans var. gattii serovar B was identified based on biochemical, physiological and serological tests. These strains were resistant (minimum inhibitory concentration 64 microg/ml) to fluconazole. This is the first report of C. neoformans var. gattii occurring in psittacine birds in Brazil.

    2011-09-01

    The objective of this review was to outline an epidemiological profile of Strongyloides stercoralis by parasitological and serological diagnosis in inhabitants, and to associate this profile with different immunosupression situations, in Brazil, over 20 years (1990-2009). The occurrence of S. stercoralis using parasitological methods was 5·5%, being 4·8% in rural and 5·0% in urban areas, characterizing the country as hyperendemic. There was a diversity of techniques used as a diagnostic tool and only 39·1% of the studies presented results based on at least 1 specific method. The occurrence increased with age, being 12·1%, for those over 60 that suggests an epidemiological condition of concern for the elderly population. Of the seroepidemiological studies in the general population the mean positivity in serum samples was 21·7% and 29·2%, using an immunofluorescence antibody test and enzyme-linked immunosorbent assay (ELISA), respectively. The occurrence of strongyloidiasis in immunosuppressed individuals was 11·8% by parasitological methods and 19·5% using immunological methods. Considering that Brazil is a tropical country and that the character of chronicity and autoinfection of the parasite that can result in severe forms of hyperinfection or dissemination makes strongyloidiasis an important medically and socially neglected problem.

    ABSTRACT OBJECTIVE Evaluate the school environments to which ninth-year students are exposed in Brazil and in the five regions of the country according to health promotion guidelines. METHODS Cross-sectional study from 2012, with a representative sample of Brazil and its macroregions. We interviewed ninth-year schoolchildren and managers of public and private schools. We proposed a score of health promotion in the school environment (EPSAE) and estimated the distribution of school members according to this score. Crude and adjusted odds ratios (OR) were used, by ordinal regression, to determine the schoolchildren and schools with higher scores, according to the independent variables. RESULTS A student is more likely to attend a school with a higher EPSAE in the South (OR = 2.80; 95%CI 2.67–2.93) if the school is private (OR = 4.52; 95%CI 4.25–4.81) and located in a state capital, as well as if the student is 15 years of age or older, has a paid job, or has parents with higher education. CONCLUSIONS The inequalities among the country’s regions and schools are significant, demonstrating the need for resources and actions that promote greater equity. PMID:28380209

    The aim of the study was to look back on the course of action involving measures of tuberculosis control in Brazil since the end of the 19th century, covering the history of social struggles and pointing out institutions and people that have dedicated themselves to looking for solutions to these issues. The Brazilian response to tuberculosis started in society with the Ligas Contra a Tuberculose (Leagues Against Tuberculosis), promoting scientific advances, such as the BCG vaccination, which begun in 1927. From the public power, the Inspetoria de Profilaxia da TB (TB Prophylaxis Inspection Service - 1920), the Serviço Nacional de Tuberculose (National Service of Tuberculosis - 1940), and the Campanha Nacional Contra a Tuberculose (National Campaign Against Tuberculosis - 1946), coordinated national policies such as chemotherapy, beginning with the discovery of streptomycin in 1944. The emergence of bacterial resistance led to the development of several therapeutic schemes. The Scheme 1 (rifampycin, hydrazide and pyrazinamid), which was the main one in 1979 and is still used nowadays, had a great epidemiological effect. The WHO declared TB a public health emergency in 1993. In response, Brazil developed some strategies; the first one was the Plano Emergencial para Controle da Tuberculose (Emergency Plan for Tuberculosis Control - 1994), prioritizing 230 municipalities. The current prospects are an effective municipalization of actions and their greater integration with the Programas de Agentes Comunitários e Saúde da Família (Humanitarian Agents and Family Health Programs).

    In recent years Brazil has experienced extraordinary growth despite the recent economic global crisis. The demand for infrared thermography products and services has accompanied this growth. Like other non-destructive testing and inspection, the results obtained by thermography are highly dependent on the skills of thermographer. Therefore, it is very important to establish a serious and recognized process of certification to assess thermographers' qualifications and help services suppliers to establish credibility with their customers and increase the confidence of these costumers on the quality of these services. The Brazilian Society of Non-Destructive Testing and Inspection, ABENDI, a non-profitable, private technical-scientific entity, recognized nationally and internationally, has observed the necessity of starting a process for certification of thermographers in Brazil. With support of a work group composed by experts from oil and energy industries, transportation, universities and manufactures, the activities started in 2005. This paper describes the economic background required for installation of the certification process, its initial steps, the main characteristics of the Brazilian certification and the expectation for initiating the certification process.

  15. Paragonimiasis: first case reported in Brazil

    Directory of Open Access Journals (Sweden)

    Antônio Carlos Moreira Lemos

    Full Text Available The authors present a case from a 59 years old white female Brazilian patient, based in Salvador-Bahia, Brazil's northeastern side area, who experienced irritative cough and progressive dyspnea, and, after 18 months, was admitted to a hospital with respiratory insufficiency. The physical exam showed diffuse rales in both hemithoraces. Initial leukogram showed 14,400 cells/mL with 14% of eosinophils and chest X-ray showed peribronchovascular infiltrate, predominating in the lower half of the lung fields, and small opaque nodules. The high-resolution computed tomography scan of the chest (HRCT presented compatible pattern with airways disease, especially from the small airways, with air trapping, tree sprouting images, central lobular nodules and bronchiectasis, making the results compatible with bronchiolitis and bronchiectasis. The transbroncho biopsy unveiled granulomatous lesion with necrosis, where was noticed a structure compatible to a parasitic case, and the research of the parasite eggs in the sputum was positive to paragonimus. After the praziquantel use, the patient presented a thick ferruginous expectoration and the result for BAAR examination was positive. The PCR exam and the sputum culture confirmed M. tuberculosis, and then the treatment for M. tuberculosis was initiated. The authors warn that this infection may have been a consequence of economics globalization process, where the importation of parasitized crustaceans might be the cause. However, there is the need of an accurate examination for the possibility of paragonimus specimens in this area of Brazil.

    The Brazil Current is a weak western boundary current, the southwest component of the South Atlantic subtropical gyre, which is the main conduit of upper ocean waters in the region. We report her the observed low frequency variability of the Brazil Current front using satellite-derived sea height anomaly and sea surface temperature observations during the 1993-2008 period. The variability of the front is studied in terms of the separation of the Brazil Current front from the continental shelf break. During the study period, estimates of this parameter indicate a shift to the south of approximately 1.5 degrees. Statistically significant changes are not observed in the geostrophic transport of the Brazil and Malvinas currents suggesting that the low-frequency changes of the Brazil Current front are governed by different mechanisms than the seasonal variability of these surface currents. Surface drifter trajectories as well as simulations using synthetic drifters are consistent with the observed shift to the south of the Brazil Current front. Trends of eddy kinetic energy, sea height anomaly, sea surface temperature and wind stress curl are also in agreement with the variability reported here. Wavelet transform analysis revealed an interesting change in the periodicity of the separation of the Brazil Current front from the continental shelf break from annual to bi-annual during 2003. Longer records together with comprehensive numerical experiments will ultimately be needed to determine the origin of these changes.

    Latin America constitutes a complex universe that shows extreme variation regarding socioeconomic and human development. Brazil is the largest and most populous Latin American country, and combines characteristics encountered in developed countries with problems typically associated with the poorest regions of the world. These disparities condition the profile of renal disease in Brazil, with glomerulonephritis still the leading cause of ESRD. Little is known about the epidemiology of renal disease in the Brazilian (or Latin American) native population, which is numerous in some Central and South American countries, but constitute a very small minority in Brazil. However, interesting information has been obtained from the Yanomamis, a tribe living in Northern Brazil and Southern Venezuela. Hypertension is virtually absent among these people, who ingest very little sodium, lending strong support to the concept that sodium retention, a "civilization" factor, plays a role in the pathogenesis of arterial hypertension. Despite Brazil's striking socioeconomic disparities, access to RRT is in principle accessible to all those in need of it. The dialysis units have been modernized in recent years, whereas the Government covers most expenses related to RRT. However, the prevalence of RRT in Brazil is currently approximately 320 per million population, less than one third as high as in the US, suggesting that ESRD may be underdiagnosed in the country. Much effort is still needed to limit the prevalence of renal disease and to improve the quality and the reach of RRT in Brazil and in Latin America.

    This article is the first in a series of international case studies developed by the American Cancer Society to illustrate use of publicly available surveillance data for regional tobacco control. A descriptive analysis of Brazil and Paraguay cigarette production and trade data from official sources. Per capita cigarette consumption for Brazil and its neighbour was calculated from 1970 to 1998 using data on production, imports, and exports from NATIONS, the National Tobacco Information Online System. A 63% decrease was observed in the estimate of per capita consumption of cigarettes in Brazil between 1986 and 1998 (from 1913 cigarettes per person in 1986 to 714 cigarettes per person in 1998) and a 16-fold increase in Paraguay was observed during the same period (from 678 cigarettes per person in 1986 to 10 929 cigarettes per person in 1998). Following Brazil's 1999 passage of a 150% cigarette export tax, cigarette exports fell 89% and Brazil's estimated per capita consumption rose to 1990 levels (based on preliminary data). Per capita consumption in Paraguay also fell to 1990 levels. These trends coincide with local evidence that large volumes of cigarettes manufactured in Brazil for export to Paraguay are smuggled back and consumed as tax-free contraband in Brazil. It is hoped that this case study will draw wider public attention to the problems that smuggling presents for tobacco control, help identify other countries confronting similar issues, and stimulate effective interventions.
