Full Text Available The wildlife trade is becoming increasingly more relevant in discussions concerning conservation biology and the sustainable management of natural resources. The aim of this study was to document the trade and breeding of wildlife in Santa Catarina state, in southern Brazil. Data was collected from annual reports (1996-2008 of wildlife breeders which were sent to IBAMA. By the end of 2008, there were 79 wildlife breeders and 11 wildlife traders distributed in Santa Catarina. Commercial breeding accounted for the highest number of breeders (51%. In total, there are 213 species of wild animals bred in the state: 177 birds, 19 mammals and 17 reptiles. Of these, 48% are native to Santa Catarina, 32% occur in other Brazilian states and 20% are exotic to Brazil. Nine percent of the species bred are vulnerable or endangered. It was observed that some breeders reported breeding unauthorized species. Altogether, 93 species are bred illegally by 19 breeders. Of these species, 48 are native to Santa Catarina and three are classified as vulnerable or in danger of extinction. We hope the data presented in this paper contributes to the development of conservation strategies and conscious use of wildlife resources in Brazil.

Full Text Available O rápido processo de urbanização que as cidades brasileiras apresentam, principalmente, a partir do final da década de 40, gera um crescimento acelerado da população urbana e produz nas cidades uma enorme demanda por terra urbanizada. O presente trabalho tem como objetivos centrais: analisar o parcelamento do solo urbano como modalidade de expansão de áreas urbanas; avaliar de que modo a incorporação de novas áreas, como urbanas, insere-se no tecido preexistente; examinar como os diversos parcelamentos do solo urbano estruturam o conjunto do tecido urbano, gerando diferentes níveis de acessibilidade geral; indicar medidas que o poder público municipal pode inserir como formas de controle e superação dos problemas apresentados presentemente. Como estudo de caso, discutiremos a formação e estruturação da cidade de Alvorada, localizada no limite leste de Porto Alegre, cidade que se originou da implantação de sucessivos loteamentos, ao invés da expansão de um núcleo urbano preexistente. O trabalho consiste, essencialmente, na reconstituição do processo de formação da estrutura urbana de Alvorada, a partir da inclusão sistemática de parcelamentos do solo ao longo do tempo e na avaliação da estrutura urbana resultante e suas relações com os potenciais de práticas sociais no espaço.

Full Text Available Para obter informações sobre a variação espacial da estrutura térmica e localizar a Corrente do Brasil, ao norte e ao sul dos bancos submarinos localizados a 20º30'S realizou-se, em abril de 1982, um levantamento oceanográfico nessa região. Dados de sensoriamento remoto foram também obtidos durante os trabalhos experimentais para um delineamento sinótico da estrutura térmica de superficie. Observou-se, ao longo da maioria das secções, um "thermostad" de 23ºC na termoclina principal. Ao longo das secções com intenso sinal baroclfnico, tal como na secção ao largo de Cabo Frio, o "thermostad" atenua-se e finalmente desaparece nas proximidades da costa, de forma semelhante ao desaparecimento da água de 18ºC na parede norte da Corrente do Golfo. A estrutura da corrente e o transporte de volume, relativos à superfície isobárica de 500 dbar, foram obtidos usando-se os dados hidrográficos e também as medidas com XBX as quais foram realizadas com espaçamentos muito menores do que o das estações hidrográficas. A comparação desses resultados, para o conjunto de observações conduzidas ao largo de Cabo Frio, indica que detalhes da corrente geostrófica não são delineados quando da utilização dos dados hidrográficos; os correspondentes valores do transporte de volume diferem em aproximadamente 17% (33 e 2,8 Sv, calculados com dados hidrográficos'e de XBX respectivamente. O balanço do transporte de volume, através de todas as secções entre 19 e 22º5, indica que a Corrente do Brasil flui através da passagem entre os bancos localizados mais próximos da costa. O transporte de volume resultante (2,9 Sv é muito próximo do valor obtido através da secção ao largo de Cabo Frio, onde supõe-se que a extensão transversal da Corrente do Brasil foi delimitada pelo conjunto de observações.In April 1982, an océanographie investigation was conducted off the Brazilian coast in order to obtain the spatial characteristics

Luís G. H. do Amaral

2005-04-01

Full Text Available O Rio Grande do Sul apresenta a maior área irrigada do Brasil, devido principalmente à lavoura de arroz irrigado por inundação. Um dos fatores que contribuem para reduzir a eficiência de irrigação nessas lavouras é o baixo grau de controle exercido pelas estruturas de distribuição de água. Os objetivos deste trabalho foram projetar e construir dois protótipos de estruturas hidráulicas para controle automático de vazão em canais de irrigação e comparar sua sensibilidade de controle de vazão com a sensibilidade de duas comportas fixas. Os protótipos construídos - uma comporta hidromecânica automática e um regulador automático de vazão - foram instalados à entrada de um canal secundário, juntamente com uma comporta-gaveta e uma comporta-vertedor, que são as estruturas mais utilizadas para controle de vazão no RS. Provocou-se uma variação de 0,20 m na altura da lâmina de água a montante, determinando-se a vazão em cada estrutura. A menor variação de vazão com a alteração da lâmina foi de 5,6%, obtida com o regulador automático de vazão, seguido da comporta-gaveta com 23,7%, da comporta hidromecânica com 30,5%, e da comporta vertedor com 1.177,2%.In Brazil, the State that presents the largest extension of irrigated lands is Rio Grande do Sul, mainly due to rice that grows under flooded conditions. One of the factors that contribute to decrease the efficiency of irrigation is the low degree of control obtained with the structures used on water distribution. The objectives of this work were to design and build two hydraulic structures for automatic flow control on irrigation channels, and to compare the flow control sensitivity of the built prototypes with two types of gates that are widely used in the rice fields at the Rio Grande do Sul State. The constructed prototypes - a hydro-mechanical gate and an automatic flow regulator - were installed at the entrance of a secondary channel, next to a sluice gate and

Proteção catódica de estruturas de concreto

Directory of Open Access Journals (Sweden)

A. Araujo

Full Text Available A adoção de técnicas de proteção às estruturas do concreto é recomendada quando há preocupação com a corrosão das armaduras de aço-carbono. Dentre as principais técnicas, destaque-se a proteção catódica que pode tanto evitar a corrosão prematura como diminuir um processo corrosivo em curso. No exterior, a técnica de proteção catódica tem sido aplicada em vários tipos de estruturas de concreto, especialmente nas sujeitas à corrosão pelo ataque de íons cloreto. No Brasil, essa técnica é pouco usada em estruturas de concreto, o que decorre, em parte, do desconhecimento sobre o seu princípio de funcionamento e da ausência de sistemas disponíveis para aplicação ao concreto (armado ou protendido. O objetivo deste trabalho é apresentar o princípio da proteção catódica para estruturas com armaduras de aço-carbono novas ou já em processo de corrosão. Os métodos de proteção catódica por corrente impressa e por anodo de sacrifício são discutidos. Um caso prático com uso de proteção catódica por corrente impressa, também, é apresentado.

Full Text Available Este artigo analisa a evolução da estrutura de propriedade de capital e de votos das empresas de capital aberto no Brasil no período 1997-2002. Sua principal contribuição reside em estimar a magnitude dos direitos de voto e de fluxo de caixa do acionista último com a maior parcela do capital votante de cada empresa. Examinam-se, também, as fontes da discrepância entre direitos de votos e de fluxo de caixa, avaliando-se a importância relativa da emissão de ações preferenciais sem direito a voto, acordos de votos, estruturas piramidais de propriedade, e posse cruzada de ações. A base de dados compreende 4478 relatórios que as empresas, cumprindo uma exigência legal, submeteram à CVM nesse período.This paper focuses on the ownership and voting structures of limited liability companies in Brazil over the period 1997-2002. Its main contribution lies in measuring the magnitude of deviations between control rights and cash-flow rights for the ultimate shareholder with the largest voting rights. Furthermore, it pinpoints how these discrepancies are generated, evaluating the relative importance of the issuance of preferred stocks with no voting rights, voting agreements, pyramidal arrangements of ownership, and cross-shareholdings. The data set embraces 4,478 reports that companies, complying with a mandatory requirement, filed to the CVM over that period.

Macroeconomic effects of oil price shocks in Brazil and in the United States

Cavalcanti, Tiago; Jalles, João Tovar

2013-01-01

Highlights: ► We find that output growth volatility in the US has been decreasing over time. ► The contribution of oil price shocks to such volatility has also been decreasing. ► In Brazil, oil shocks do not seem to have a clear impact on growth. ► They account for a small fraction of the Brazilian inflation and output volatility. ► Counterfactuals show US output would be 10% less volatile with Brazil’s oil import share. - Abstract: This paper studies the effects of oil price shocks in the last 30 years on the Brazilian and American inflation rate and rhythm of economic activity. The Brazilian and the United States economies are interesting polar cases, since they had a completely different path on the oil import dependence rate. While the oil import dependence rate has increase sharply in the United States (US), it has decreased substantially in Brazil. We found that output growth volatility in the United States has been decreasing over time as well as the contribution of oil price shocks to such volatility, despite the increase in oil import dependence. Inflation volatility has also been decreasing but oil price shocks are accounting for a larger fraction of this volatility in the US. In Brazil, such shocks do not seem to have a clear impact on output growth and they account for a very small fraction of the Brazilian inflation and output growth rate volatility. We finally run some counterfactual experiments to analyze how real output growth in the United States would had been if net oil import share in the United States behaved similarly to what was observed in Brazil. We conclude that output level would be roughly the same, however, it would be about 10% less volatile if the US had the actual Brazilian oil import share

Results point to the fact that even a large shock like the one simulated wouldn't have a strong impact on poverty reduction in Brazil, although the results are concentrated on the poorest households.Este trabalho analisa os efeitos potenciais da formação da ALCA sobre os níveis de pobreza e distribuição de renda no Brasil. A análise é conduzida através de um Modelo Aplicado de Equilíbrio Geral e de Micro-simulação estático, calibrado com os dados da PNAD 2001. O modelo distingue na sua estrutura 112.055 domicílios e 263.938 adultos, 42 atividades produtivas, 52 produtos, e 27 regiões. Os resultados apontam para o fato de que mesmo mudanças tarifárias grandes como as aqui simuladas não trariam um forte impacto sobre a pobreza no Brasil, embora os resultados estejam concentrados nos domicílios mais pobres.

Full Text Available In the arid and semiarid environments of the world, microhabitats serve as models for the structure of vegetation communities. The goal of this study was to identify differences in the structures of the herbaceous communities growing on a crystalline substrate and those growing on a sedimentary substrate in a semiarid region of northeastern Brazil. One hundred 1 × 1 m plots were established in each area for quantitative sampling, with 69 species recorded in the crystalline area and 76 in the sedimentary area. The average plant density was higher in the sedimentary area, and average diameters and heights were greater in the crystalline area. The families and species with a high Importance Value Index (IVI and a high Mixed Ecological Value Index (MEVI differed between the areas. Of the species with high densities, only four were found in both areas. Shannon-Weiner diversity index values in the crystalline (2.96 nats/ind.-1 and sedimentary (2.89 nats/ind.-1 areas were similar. Evenness values on both substrates were also similar (0.72 and 0.71 in the crystalline and sedimentary areas, respectively. This study shows that variations in plant establishment conditions between crystalline and sedimentary areas in a semiarid region of northeastern Brazil should be considered as structure-modeling factors for the herbaceous community.Nos ambientes áridos e semiáridos do mundo, os micro-habitats modelam a estrutura das comunidades vegetais. O objetivo deste estudo foi identificar diferenças nas estruturas das comunidades herbáceas instaladas sobre o solo do embasamento cristalino e a bacia sedimentar em uma região semiárida do Nordeste do Brasil.

Silveira, Geraldo T R; Chang, Shoou-Yuh

2010-11-01

This paper presents an overview of cell phone recycling programs currently available in the United States. At the same time, it also provides analyses of the current recycling situation and possible recycling alternatives for Brazil. Although there are several recycling options in the United States, collection rates are still only 10% of all potential devices because customers are not aware of these possibilities. The whole system is financially based on reselling refurbished cell phones and recycled materials to developing countries which represent an effective and strong market. Several recyclers offer funds to collection partners who are either charities or who work with charities while obtaining the materials that they need in order to run their operations. A mobile phone recycling system for Brazil considering the United States experience and the Extended Producer Responsibility (EPR) principle is suggested. A deposit/refund/advance-recycling fee is proposed which might be implemented as a voluntary industrial initiative managed by PRO Brazil, a producer responsibility organization. One widespread public-private agreement will integrate all mobile phone stakeholders, and environmental education actions and promotional events will promote citizen's participation.

Full Text Available Introduction: Leptospirosis is an acute bacterial disease, that has global distribution and manifests itself in subclinical or asymptomatic way, having mild or severe conditions that can lead to the death of the patient. Objective: To identify, among the municipalities of the state of Acre, Brazil, those with the highest incidence of leptospirosis between 2010 and 2015, and in addition, to determine the prevalence of this disease between the sexes. Methods: Descriptive study, of documentary character, with epidemiological base and quantitative approach. It was made by available documents through the Department of Informatics of the Unified Health System of Brazil (DATASUS and also by the Health Secretary of State of Acre (SESACRE. Variables were selected as sex, age and year of notification. Regarding the analysis, it is emphasized that it was quantitative and descriptive and the results were presented in tables built in Microsoft Word. Results: It was found that the capital of the state of Acre, Rio Branco, led every year, contributing to the higher proportion of notifications related to leptospirosis. Regarding gender, there was a predilection for males and among age groups, the period of 20 to 39 years contributes to the greater number of cases of the disease. Conclusion: Leptospirosis is a worldwide public health problem and in the state of Acre, the high rainfall, the agglomeration of low income combined with inadequate sanitation, collaborate to infestation of transmitters animals, providing high rates of the disease. Thus, it appears that these high numbers can probably be attributed to the ineffectiveness of preventive activities, as well as insufficient investment directed to social policies and infrastructure sectors. Keywords: Infectious Disease. Leptospirosis. Prevalence. Incidence.

The opening of the Brazilian economy and the end of the state-owned oil company PETROBRAS monopoly made possible for national and international companies to become concessionaires of the rights and obligations regarding the exploration, development and production of oil and natural gas. The increasing of the oil reserves and production, together with the technological development and the more restricted environmental legislation, resulted in a gradual increased participation of the natural gas in the Brazilian domestic energy supply. Around 3% for many years, the participation of gas in the Brazilian domestic energy supply has increased to 7.5% in 2002, as mentioned in the 2003 Brazil Energy Balance (BEN). The 2003 production was more than 100 millions boe, and the import was more than 37 millions boe according to the National Oil Agency (ANP).

Full Text Available Neste trabalho, utiliza-se o comércio internacional como uma lente para captar a intensidade tecnológica da estrutura produtiva brasileira. Considera-se que produtos com maior conteúdo tecnológico vistos pelo lado das exportações indicam melhor qualificação da indústria local, contribuindo para uma inserção mais dinâmica nas relações de trocas internacionais. Há alguns indicadores sugeridos para avaliar a evolução da intensidade tecnológica do comércio brasileiro, inclusive a destinação das exportações e uma comparação com a estrutura comercial da Organização para a Cooperação e de Desenvolvimento Econômico (OCDE. Discute-se, dessa forma, em que medida a mudança estrutural no Brasil tem favorecido os setores dinâmicos na tecnologia e comércio. Finalmente, uma matriz de dinamismo comercial é sugerida, combinando indicadores de intensidade tecnológica com o índice de vantagem comparativa revelada.In this work, international trade is used as a specific vantage point to analyze the technological intensity of Brazil´s productive structure. Exports with a higher technological intensity indicate greater local technological capabilities, this leading to a more dynamic international insertion regarding terms of trade. Several indicators are used to measure this intensity, among which are the destination of Brazilian exports and a comparison of Brazilian and OECD exports. These are used to assess the extent to which structural change in Brazil has favored sectors in which technical change and demand growth are higher. Lastly, a matrix of trade dynamism is constructed, crossing the indicators of technological intensity with the index of revealed comparative advantage.

How Brazil outpaced the United States when it came to AIDS: the politics of civic infiltration, reputation, and strategic internationalization.

Science.gov (United States)

Gómez, Eduardo J

2011-04-01

Using a temporal approach dividing the reform process into two periods, this article explains how both Brazil and the United States were slow to respond to AIDS. However, Brazil eventually outpaced the United States in its response due to international rather than democratic pressures. Since the early 1990s, Brazil's success has been attributed to "strategic internationalization": the concomitant acceptance and rejection of global pressure for institutional change and antiretroviral treatment, respectively. The formation of tripartite partnerships among donors, AIDS officials, and nongovernmental organizations has allowed Brazil to avoid foreign aid dependency, while generating ongoing incentives for influential AIDS officials to incessantly pressure Congress for additional funding. Given the heightened international media attention, concern about Brazil's reputation has contributed to a high level of political commitment. By contrast, the United States' more isolationist relationship with the international community, its focus on leading the global financing of AIDS efforts, and the absence of tripartite partnerships have prevented political leaders from adequately responding to the ongoing urban AIDS crisis. Thus, Brazil shows that strategically working with the international health community for domestic rather than international influence is vital for a sustained and effective response to AIDS.

Full Text Available In the production chain of soybeans in Brazil a sizable part of the corresponding cost structure is the result of logistics costs. Given the location of its production sites, distant from the ocean, the optimization of the transportation costs is essential for preserving competitiveness. Using nonlinear programming, this study proposes a spatial multimodal and temporal equilibrium model. The applicability of the model is tested with a case study regarding the exports of the soybeans produced in three states in the northern part of the Brazilian cerrado region. In the state of Tocantins, the effects of infrastructure investments in the competitiveness of the production are described through four proposed scenarios, while the basic scenario compares the three states. The data are treated using the GAMS/MINOS program. The study asserts that soybean production will be more competitive if warehousing facilities are used extensively and when the project hydroway becomes operational.Na cadeia de produção da soja no Brasil, parte substancial da estrutura correspondente dos custos é resultado dos custos logísticos. Dada a localização das áreas produtivas, distante do oceano, a otimização dos custos de transporte é essencial para garantir a competitividade. Usando programação não-linear, este estudo propõe um modelo de equilíbrio espacial temporal e multimodal. A aplicabilidade do modelo proposto é testada com um estudo de caso referente às exportações de soja produzida em três estados na parte norte do cerrado brasileiro. No estado de Tocantins, o efeito na competitividade de investimentos na infraestrutura de transporte estão descritos por meio de quatro cenários, enquanto que os três estados são comparados pelo cenário básico. Os dados são tratados usando o programa GAMS/MINOS. O estudo assegura que a produção de soja nesses estados será mais competitiva se armazéns forem usados mais extensamente e quando o projeto

Conflito social e welfare state: Estado e desenvolvimento social no Brasil Social conflict and welfare state: state and social development in Brazil

Fábio Guedes Gomes

2006-04-01

Full Text Available Este artigo argumenta que no Brasil a luta de classes não alcançou dimensões profundas que pudesse engendrar a constituição do welfare state. Ao contrário, o Estado, sobretudo sua forma mais moderna, capitalista, que emergiu a partir da década de 1930, sempre se antecipou aos movimentos sociais que representassem ameaças de rupturas. De forma repressiva, o Estado brasileiro desde o Império dissipou os conflitos com o objetivo de manter uma certa harmonia em favor do processo de expansão e reprodução capitalista e a integração dos espaços regionais. O artigo, portanto, é uma tentativa, prematura, de entender o processo de constituição dos sistemas de seguridade social, analisando as experiências de alguns países e suas respectivas características, com isso confrontando alguns estudos e realizando comparações com a dinâmica da luta de classes no Brasil e a função do Estado nesse processo.This article defends the theory that the class struggle in Brazil has not been able to engender the formation of a welfare state. On the contrary, the nation which emerged in the 1930s - above all in its more modern capitalistic form - has always prevented social movements that could pose any threat of a rupture. Since when it was a monarchy, Brazil has dealt with its conflicts in a repressive fashion, with the goal of maintaining a certain harmony in the interest of the expansion and the propagation of capitalism as well as regional integration. This text, therefore, is an attempt, albeit premature, to understand the process involving the formation of the social security system in Brazil, by analyzing the experiences of a number of countries and their respective characteristics, thus examining a few studies and making comparisons with the class struggle dynamic in Brazil and the role of the State in this process.

Background: Male genital human papillomavirus (HPV) prevalence and incidence has been reported to vary by geographical location. Our objective was to assess the natural history of genital HPV by country among men with a median of 48 months of follow-up. Methods: Men ages 18-70 years were recruited from United States ( n = 1,326), Mexico ( n = 1,349), and Brazil ( n = 1,410). Genital specimens were collected every 6 months and HPV genotyping identified 37 HPV genotypes. Prevalence of HPV was compared between the three countries using the Fisher exact test. Incidence rates and 95% confidence intervals were calculated. The median time to HPV clearance among men with an incident infection was estimated using the Kaplan-Meier method. Results: The prevalence and incidence of the genital HPV types known to cause disease in males (HPV 16 and 6) was significantly higher among men from Brazil than men from Mexico. Prevalence and incidence of those genital HPV types in the United States varied between being comparable with those of Mexico or Brazil. Although genital HPV16 duration was significantly longer in Brazil ( P = 0.04) compared with Mexico and the United States, HPV6 duration was shortest in Brazil ( P = 0.03) compared with Mexico and the United States. Conclusions: Men in Brazil and Mexico often have similar, if not higher prevalence of HPV compared with men from the United States. Impact: Currently, there is no routine screening for genital HPV among males and while HPV is common in men, and most naturally clear the infection, a proportion of men do develop HPV-related diseases. Men may benefit from gender-neutral vaccine policies. Cancer Epidemiol Biomarkers Prev; 26(7); 1043-52. ©2017 AACR . ©2017 American Association for Cancer Research.

2004-08-01

This research presents a comparative assessment of the regulation models of the nuclear sector in Argentina - under the responsibility of the Autoridad Regulatoria Nuclear (ARN), and Brazil - under the responsibility of Comissao Nacional de Energia Nuclear (CNEN), trying to identify which model is more adequate aiming the safe use of nuclear energy. Due to the methodology adopted, the theoretical framework resulted in criteria of analysis that corresponds to the characteristics of the Brazilian regulatory agencies created for other economic sector during the State reform staring in the middle of the nineties. Later, these criteria of analysis were used as comparison patterns between the regulation models of the nuclear sectors of Argentina and Brazil. The comparative assessment showed that the regulatory structure of the nuclear sector in Argentina seems to be more adequate, concerning the safe use of nuclear energy, than the model adopted in Brazil by CNEN, because its incorporates the criteria of functional, institutional and financial independence, competence definitions, technical excellence and transparency, indispensable to the development of its functions with autonomy, ethics, exemption and agility.

This is an overview of the current biomass feedstock efforts in Brazil, Canada, and the United States. The report from Brazil provides an historical perspective of incentive programs, the charcoal and fuelwood energy programs, the alcohol program, and other biomass energy efforts. The efforts in Brazil, particularly with the sugar cane to ethanol and the charcoal and fuelwood programs, dwarfs other commercial biomass systems in the Americas. One of the bright spots in the future is the Biomass Integrated Gasification/Gas Turbine Electricity Project initially funded in 1992. The sugar cane-based ethanol industry continues to develop higher yielding cane varieties and more efficient microorganisms to convert the sugar cane carbohydrates into alcohol. In Canada a number of important institutions and enterprises taking part in the economical development of the country are involved in biomass research and development including various aspects of the biomass such as forestry, agricultural, industrial, urban, food processing, fisheries and peat bogs. Biomass feedstock research in the United States is evolving to reflect Department of Energy priorities. Greater emphasis is placed on leveraging research with the private sector contributing a greater share of funds, for both research and demonstration projects. The feedstock program, managed by ORNL, is focused on limited model species centered at a regional level using a multidisciplinary approach. Activities include a stronger emphasis on emerging environmental issues such as biodiversity, sustainability and habitat management. DOE also is a supporter of the National Biofuels Roundtable, which is developing principles for producing biomass energy in an economically viable and ecologically sound manner. Geographical Information Systems are also being developed as tools to quantify and characterize the potential supply of energy crops in various regions.

Full Text Available SUMMARY Malaria is a major health problem for people who live on the border between Brazil and French Guiana. Here we discuss Plasmodium vivax distribution pattern in the town of Oiapoque, Amapá State using the circumsporozoite (CS gene as a marker. Ninety-one peripheral blood samples from P. vivax patients have been studied. Of these, 64 individuals were from the municipality of Oiapoque (Amapá State, Brazil and 27 patients from French Guiana (August to December 2011. DNA extraction was performed, and a fragment of the P. vivax CS gene was subsequently analyzed using PCR/RFLP. The VK210 genotype was the most common in both countries (48.36% in Brazil and 14.28% in French Guiana, followed by the P. vivax-like (1.10% in both Brazil and French Guiana and VK247 (1.10% only in Brazil in single infections. We were able to detect all three CS genotypes simultaneously in mixed infections. There were no statistically significant differences either regarding infection site or parasitaemia among individuals with different genotypes. These results suggest that the same genotypes circulating in French Guiana are found in the municipality of Oiapoque in Brazil. These findings suggest that there may be a dispersion of parasitic populations occurring between the two countries. Most likely, this distribution is associated with prolonged and/or more complex transmission patterns of these genotypes in Brazil, bordering French Guiana.

The purpose of the present study was to reconstruct the phylogeny of dengue virus serotype 4 (DENV-4) that was circulating in Espírito Santo state, Brazil, in 2013 and 2014, and to discuss the epidemiological implications associated with this evolutionary hypothesis. Partial envelope gene of eight DENV-4 samples from Espírito Santo state were sequenced and aligned with 72 worldwide DENV-4 reference sequences from GenBank. A phylogenetic tree was reconstructed through Bayesian Inference and the Time of the Most Recent Common Ancestor was estimated. The study detected the circulation of DENV-4 genotype II in Espírito Santo state, which was closely related to strains from the states of Mato Grosso collected in 2012 and of São Paulo sampled in 2015. This cluster emerged around 2011, approximately 4 years after the entry of the genotype II in Brazil through its northern states, possibly imported from Venezuela and Colombia. This is so far the first phylogenetic study of the DENV-4 circulating in Espírito Santo state and shows the importance of an internal route of dengue viral circulation in Brazil to the introduction of the virus into this state.

Full Text Available ABSTRACT Knowledge of weed floristic composition and phytosociology are key factors for improving weed management in pastures. Information on weed species that occur in pastures in Northeast Brazil, particularly in Maranhão State is very limited. It is, therefore, important, to search for information to help farmers to control weeds in livestock farming. This paper describes the weed flora diversity and community structure parameters, including density, frequency, abundance and importance value for each weed species found in five pastures of same age and management in Maranhão State, Northeast Brazil. The weed survey was carried out using a wooden frame (80 cm x 30 cm placed randomly on the soil surface 30 times in each pasture (n = 150. Weeds were pulled out, separated by species and counted. The weed flora was represented by 996 individuals, from nine families, 15 genera and 19 species. Weed density within pastures was of 44.3 plants m-2. The weed flora was dominated by species of the Cyperaceae and Poaceae families. The most important weed species based on Importance Value were Eragrostis ciliaris (IV = 32.97, Cyperus rotundus (IV = 31,95, Cyperus luzulae (IV = 27,50, Cyperus sphacelatus (IV = 27,42, Pycreus lanceolatus (IV = 27,33 Cyperus haspan (IV = 25,72 and Eleusine indica (IV = 23,49.

Bastos, Jorge Tiago; Shen, Yongjun; Hermans, Elke; Brijs, Tom; Wets, Geert; Ferraz, Antonio Clóvis Pinto

2015-08-01

The intense economic growth experienced by Brazil in recent decades and its consequent explosive motorization process have evidenced an undesirable impact: the increasing and unbroken trend in traffic fatality numbers. In order to contribute to road safety diagnosis on a national level, this study presents a research into two main indicators available in Brazil: mortality rate (represented by fatalities per capita) and fatality rate (represented by two sub-indicators, i.e., fatalities per vehicle and fatalities per vehicle kilometer traveled). These indicators were aggregated into a composite indicator or index through a multiple layer data envelopment analysis (DEA) composite indicator model, which looks for the optimum combination of indicators' weights for each decision-making unit, in this case 27 Brazilian states. The index score represents the road safety performance, based on which a ranking of states can be made. Since such a model has never been applied for road safety evaluation in Brazil, its parameters were calibrated based on the experience of more consolidated European Union research in ranking its member countries using DEA techniques. Secondly, cluster analysis was conducted aiming to provide more realistic performance comparisons and, finally, the sensitivity of the results was measured through a bootstrapping method application. It can be concluded that by combining fatality indicators, defining clusters and applying bootstrapping procedures a trustworthy ranking can be created, which is valuable for nationwide road safety planning.

Understanding the United States and Brazil's response to obesity: institutional conversion, policy reform, and the lessons learned.

Science.gov (United States)

Gómez, Eduardo J

2015-06-10

In the United States (US) and Brazil, obesity has emerged as a health epidemic. This article is driven by the following research questions: how did the US and Brazil's federal institutions respond to obesity? And how did these responses affect policy implementation? The aim of this article is therefore to conduct a comparative case study analysis of how these nations' institutions responded in order to determine the key lessons learned. This study uses primary and secondary qualitative data to substantiate causal arguments and factual claims. Brazil shows that converting preexisting federal agencies working in primary healthcare to emphasize the provision of obesity prevention services can facilitate policy implementation, especially in rural areas. Brazil also reveals the importance of targeting federal grant support to the highest obesity prevalence areas and imposing grant conditionalities, while illustrating how the incorporation of social health movements into the bureaucracy facilitates the early adoption of nutrition and obesity policies. None of these reforms were pursued in the US. Brazil's government has engaged in innovative institutional conversion processes aiding its ability to sustain its centralized influence when implementing obesity policy. The US government's adoption of Brazil's institutional innovations may help to strengthen its policy response.

Full Text Available This article compares the career profiles of judges from the highest bodies of the Judiciary in Brazil and the United States of America, examining the biographies of all the ministros of the Supreme Court of Justice (Empire and of the Supreme Federal Tribunal (Republic in Brazil, and of all the justices of the Supreme Court of the United States, appointed until 2008 in both cases. Based on the sociology of political elites perspective, the article examines data concerning academic background, geographic circulation and the different professional experiences — legal, political and linked to the administration of the State’s coercive activity (police or military — lived through by future members of the Supreme Courts of Brazil and the United States so as to identify the types of individuals recommended to join the top bodies of the Judiciary in the two countries. In this sense, different State-building processes are identified on the basis of the examination of Brazilian and US judicial elites, suggesting a more fragmented and diverse trajectory in the case of US justices, and greater homogeneity and centralization in the case of their Brazilian counterparts.

Coccidioidomycosis is an endemic infection in the Americas caused by the dimorphic fungi Coccidioides immitis and Coccidioides posadasii. Although the disease occurs in Brazil in sporadic form, little information about these cases is available. In this study, we summarize the most important clinical, epidemiologic, and diagnostic features of coccidioidomycosis in Ceará State (Northeast Brazil) during the past 12 years. In this period, 19 cases of coccidioidomycosis were diagnosed. All the patients were young males and came from semiarid areas of the state. The majority of cases were associated to armadillo hunting, and pulmonary disease was the most common clinical presentation. In our laboratory, coccidioidomycosis was confirmed by culture, serology, and polymerase chain reaction tests, which together were very suitable for the diagnosis of this disease. Based on our local experience, we believe many cases of this disease are misdiagnosed or not diagnosed in our region. Therefore, some strategies for improvement of diagnosis should be encouraged by local authorities.

The detection of enterovirus (EV in cerebrospinal fluid was performed using cell culture techniques, RT-PCR, nested PCR and nucleotide sequencing. The ages of the 91 patients ranged from 60 years old (median age 15.90 years. Fever (87.1%, headache (77.0%, vomiting (61.5% and stiffness (61.5% were the most frequent symptoms. Of 91 samples analyzed, 18 (19.8% were positive for EV. Twelve were detected only by RT- PCR followed by nested PCR, whereas six were found by both cell culture and RT-PCR. From the last group, five were sequenced and classified as echovirus 30 (Echo 30. Phylogenetic analyses revealed that Echo 30 detected in Northern Brazil clustered within a unique group with a bootstrap value of 100% and could constitute a new subgroup (4c according to the phylogenetic tree described by Oberste et al. (1999. This study described the first molecular characterization of Echo 30 in Brazil and this will certainly contribute to future molecular analyses involving strains detected in other regions of Brazil.

Diversity and genetic structure in natural populations of Hancornia speciosa var. speciosa Gomes in northeastern Brazil Diversidade e estrutura genética em populações naturais de Hancornia speciosa var. speciosa Gomes no nordeste do Brasil

Full Text Available Hancornia speciosa Gomes is a fruit tree native from Brazil that belongs to Apocinaceae family, and is popularly known as Mangabeira. Its fruits are widely consumed raw or processed as fruit jam, juices and ice creams, which have made it a target of intense exploitation. The extractive activities and intense human activity on the environment of natural occurrence of H. speciosa has caused genetic erosion in the species and little is known about the ecology or genetic structure of natural populations. The objective of this research was the evaluation of the genetic diversity and genetic structure of H. speciosa var. speciosa. The genetic variability was assessed using 11 allozyme loci with a sample of 164 individuals distributed in six natural populations located in the States of Pernambuco and Alagoas, Northeastern Brazil. The results showed a high level of genetic diversity within the species (e= 0.36 seeing that the most of the genetic variability of H. speciosa var. speciosa is within its natural populations with low difference among populations ( or = 0.081. The inbreeding values within ( = -0.555 and among populations ( =-0.428 were low showing lacking of endogamy and a surplus of heterozygotes. The estimated gene flow ( m was high, ranging from 2.20 to 13.18, indicating to be enough to prevent the effects of genetic drift and genetic differentiation among populations. The multivariate analyses indicated that there is a relationship between genetic and geographical distances, which was confirmed by a spatial pattern analysis using Mantel test (r = 0.3598; p = 0.0920 with 1000 random permutations. The high genetic diversity index in these populations indicates potential for in situ genetic conservation.Hancornia speciosa Gomes é uma árvore frutífera nativa do Brasil, pertencente à família Apocinaceae, e é conhecida popularmente como Mangabeira.

Binder, M C; Almeida, I M

1999-01-01

This paper discusses, within the prevailing Brazilian situation, the possibility of applying "causal tree" (CT) method in investigating occupational accidents by safety personnel in the public health services and workers' unions. The method was developed during the seventies in France, for use by plant safety personnel. The authors used this method in Botucatu, state of São Paulo, Brazil, in order to investigate 40 serious occupational accidents that occurred in industrial plants during the second half of 1993, that had been registered by social security. In these cases, the predominance of situations in which the lack of safety measures were identified by inspection indicates that in most instances, the use of CT is unnecessary. However, the authors discuss its use by safety personnel from the public health services and workers' unions to investigate certain accidents to contribute to the knowledge base and help overcome the cultural based guilt which, in Brazil, has turned the victim into the person responsible for the accident.

Full Text Available Female sexual hormones have attracted the attention of the scientific community due to the effects that they cause by interfering in the endocrine system. Many contemporary studies have sought to monitor some of the main female sexual hormones in surface waters in Brazil. Current article evaluates the presence of 17β-estradiol, 17α-ethinylestradiol, estrone and progesterone in the surface waters of Curitibaand the surrounding metropolitan area in the state of Paraná, Brazil, by high-performance liquid chromatography (HPLC, performed at 7 different sites. The study revealed that a range of concentrations between 0.07 and 13.45 µg L-1 of female sexual hormones was extant; higher values than these were found in other regions ofBrazil and in other countries. Higher concentrations have been attributed to the region´s sanitation due to large sewage amounts. Sewage discharge has also been confirmed by results of limnological parameters.

Brazil is one of 22 countries that accounts for 80% of the tuberculosis global burden. The highest incidence rates in Brazil occur in the States of Amazonas and Rio de Janeiro. The aim of this study was to describe the temporal distribution of TB in the State of Amazonas. Between 2001 and 2011, 28,198 cases of tuberculosis were reported in Amazonas, distributed among 62 municipalities, with the capital Manaus reporting the highest (68.7% concentration of cases. Tuberculosis was more prevalent among males (59.3% aged 15 to 34 years old (45.5%, whose race/color was predominantly pardo (64.7% and who had pulmonary TB (84.3%. During this period, 81 cases of multidrug-resistant TB were registered, of which the highest concentration was reported from 2008 onward (p = 0.002. The municipalities with the largest numbers of indigenous individuals affected were São Gabriel da Cachoeira (93%, Itamarati (78.1%, and Santa Isabel do Rio Negro (70.1%.

Full Text Available A field survey of flowering plants used as food resource by the adults of Heliconius erato phyllis (Fabricius, 1775 was carried out in four sites located in Rio Grande do Sul state, Brazil. Samples were taken in preserved areas of the Atlantic Rain and Myrtaceae forests, an Eucalyptus plantation, and an urban park. Adult feeding frequencies on flowers were registered monthly from December 1996 to May 1997, on plants located on previously marked 200 m long transects. Flowers on which H. erato phyllis fed in the field were collected, drawn and morphometrically characterized. Feeding was registered on flowers of twenty-three species, of which seventeen are new records for H. erato in Brazil . The use of a given plant varied among localities, as a function of its corresponding abundance. The most visited flowers were those of Lantana camara L. and Stachytarpheta cayennensis (Rich. Vahl, followed by Dahliapinnata Voss in the urban site. The data suggest the existence of size and shape convergence between the proboscis and the small, tubular flowers upon which H. eratophyllis feeds. They also indicate that H. eratophyllis adults have an opportunistic nectar feeding / pollen gathering habit, using several of those flowers available in a given time and locality that fit such a morphometrical pattern. Since plant species of both primitive and derived families are used, there is no indication that phylogenetic constraints play a major role in this association, nor that color of flowers, growth pattern or size of the plants are relevant in determining their use by H. erato phyllis.

Pharmaceutical companies vs. the State: who is responsible for post-trial provision of drugs in Brazil?

Science.gov (United States)

Wang, Daniel Wei L; Ferraz, Octavio Luiz Motta

2012-01-01

This paper discusses the post-trial access to drugs for patients who participated in clinical trials in Brazil. The ethical guidance for clinical trials in Brazil is arguably one of the clearest in the world in attributing to research sponsors the responsibility for providing post-trial drugs to patients who participated in their experiments. The Federal Constitution recognizes health as a fundamental right to be fulfilled by the State. Based on the Brazilian constitution and on the National Health Council resolutions, courts have been accepting patients' claims and ordering the State and the pharmaceutical companies to provide these patients with the tested treatment in the quantity and duration they need it. This generous interpretation of the duties of the pharmaceutical companies and the State makes the Brazilian model for post-trial access unique when compared to the experience of other countries and thus should be followed with attention by future research in order to assess its consequences for patients, research sponsors, and the public health system. © 2012 American Society of Law, Medicine & Ethics, Inc.

Soil samples from Parana State, Brazil, were collected in 1991 and compared with others collected at some location in March 1977 and at the end of 1983. Pedological analyses were practiced on the samples and 137 Cs and 232 Th, 226 Ra and 40 K activities were determined by gamma-ray spectrometry. A latitude dependence of 137 Cs was found as well. It was impossible to determine the 137 Cs contribution from Chernobyl nuclear accident because of low fallout and intense leaching, erosion and re-suspension in soils of regions with high annual precipitation. Natural radionuclides did not show such effects. (author) 39 refs; 6 tabs

Full Text Available The order Asparagales comprises 14 families, five of which occur in Brazil. Amaryllidaceae is a family of economic relevance and includes numerous ornamental genera. The genus Hippeastrum is widely distributed in Brazil and comprises 34 species, 11 of which occur in areas of restinga (coastal woodland and Atlantic Forest in the state of Rio de Janeiro. The morphology of Hippeastrum has not been extensively studied in Brazil, where only a few systematic floristic surveys have been carried out with native species. In field studies and reviews of herbarium collections, we identified five Hippeastrum species occurring in areas of restinga in the state of Rio de Janeiro. The five species identified could be distinguished according to the following palynological characteristics: pollen grain size, polarity, pollen units, shape, aperture (number and type, exine sculpture, colpus length and pattern of sexine ornamentation. Of the five species identified, Hippeastrum aulicum Herb. and H. glaucescens (Ker Gawl. Herb. were not identified in the field. Among the three species that were found in the field, H. striatum had the widest distribution in the study area, whereas the distribution of H. reticulatum was restricted to a single area of restinga, in the Jaconé district of the municipality of Saquarema. Through palynological examinations of specimens from herbaria in the state of Rio de Janeiro, we were able to confirm the identity of all five species of Hippeastrum studied. Our data represent a relevant contribution to increasing knowledge of this plant group in the region and will aid in future conservation efforts.

Full Text Available A retrospective serologic study was carried out in Fortaleza, State of Ceará, Brazil, in order to detect the dengue virus activity before recognizing the epidemic of 1994. Mac-Elisa was performed by using a mixture of specific DEN-1 and DEN-2 antigens on serum samples from the Emilio Ribas Laboratory collection. Samples were obtained from 1,224 patients with exanthematic febrile disease and negative serological results for rubella. All specimens were taken during November 1993 to May 1994. The results confirmed dengue infections in Fortaleza by November 1993, approximately six months before the beginning of the epidemic, proving how misleading diagnosis of dengue infection are still troublesome, in spite of the strong dengue activity in Ceará. The authors stress the urgent necessity to implement the active surveillance system in order to prevent another extensive dengue fever epidemics in the state. Epidemiological background of the dengue activity in the State of Ceará is also described.

Full Text Available A dinâmica de operação dos filtros de areia afeta o desempenho hidráulico do sistema de irrigação, elevando a perda de carga e alterando a altura manométrica total do sistema. Buscando entender parte dessa dinâmica, o objetivo deste trabalho foi determinar o efeito da estrutura interna de filtros de areia na perda de carga de três modelos de equipamentos fabricados no Brasil, sem a presença do elemento filtrante e utilizando água limpa. Adicionalmente, com o ajuste do modelo matemático exponencial aos dados experimentais, procurou-se estabelecer comparações entre os tipos de estrutura dos filtros avaliados. Os ensaios foram realizados em um módulo experimental construído no Laboratório de Hidráulica e Irrigação da FEAGRI/UNICAMP. Os resultados mostraram que a estrutura hidráulica interna dos filtros determinou comportamentos hidráulicos diferenciados e que os tipos de estruturas (placa difusora e drenos alteraram o padrão de operação dos modelos ensaiados. A função matemática proposta representou, significativamente, o fenômeno físico de perda de carga para as condições do experimento.The dynamic of operation of sand filters affect the hydraulic performance of irrigation systems, increasing the head loss and changing the total dynamic head of the system. Trying to understand part of this dynamic, the objective of this research was to determine the effect of internal hydraulic structures in the head loss of three sand filters of commercial models, manufactured in Brazil and operating without the filter layer and with clean water. In addition, using an exponential mathematical model adjusted to the experimental data, comparisons among types of structure of each evaluated filter were performed. The trails were accomplished in the experimental module developed in the Laboratory of Hydraulics and Irrigation of FEAGRI / UNICAMP. The results showed that the filters structures determined differentiate hydraulic behaviors

Brazil in the global energy world

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 O presente estudo teve como objetivo compreender o sistema organizacional de um meio de hospedagem do tipo Cama e Café a partir da relação agência/estrutura, ou seja, da relação entre as pessoas e a estrutura organizacional da empresa. A análise dessa relação buscou avaliar como esses elementos (agente e estrutura se influenciam a partir do modelo Multidimensional-Reflexivo (ALVES, 2004. Para tanto, buscou-se fundamentação na teoria de Weber, nomeadamente, os conceitos de Ação Social, Tipo Ideal e Estruturas puras de Dominação. Como metodologia, realizou-se um estudo de caso de natureza qualitativa de um meio de hospedagem do tipo Cama e Café. A coleta de dados se deu por entrevistas semiestruturadas, e as informações foram tratadas com a técnica de análise do discurso. Com o resultado da pesquisa verificou-se que existe a supremacia do agente sobre a estrutura na empresa e o subtipo em que se enquadra o ‘cama e café’ é o organizacional-administrativo patriarcal reformista, ou seja, em que o líder da empresa têm autonomia administrativa e é livre da tradição, e, assim, promove mudanças já que a coordenação e o controle são centrados nele.

Full Text Available O presente trabalho analisa as relações de interdependência existentes entre a estrutura da empresa e as estratégias a serem implementadas. É feita uma breve revisão da literatura sobre estratégia, administração estratégica e as diversas formas de conduzir a implementação das que se apresentam como as mais adequadas à consecução dos objetivos organizacionais. Foram analisados os modelos tradicionais de estrutura organizacional, bem como as vantagens e desvantagens estratégicas que cada um apresenta. Por fim, foram estudadas as abordagens de diferentes autores sobre as relações de interdependência entre a estrutura da empresa e as suas estratégias. Em conclusão, verifica-se que, embora as estratégias da empresa possam ser fixadas a partir da análise da sua estrutura organizacional, dos seus pontos fortes e fracos, esta atitude nem sempre é viável. Numa época em que as tecnologias evoluem de forma extremamente rápida e a competitividade se acelera em nível global, tornam-se necessárias estruturas organizacionais flexíveis, que possam modificar-se rapidamente, para atender às estratégias capazes de permitir a adequada inserção da empresa em um ambiente externo extremamente volátil.The interdependent relations that exist between the structure of an organization and the organizational strategies to be implemented were analyzed. A review was made of literature on strategy, strategic management and methods of implementing strategies appropriate for organization objectives. Traditional models of organization structures were then analyzed as well as the inherent strategic advantages and disadvantages. Then the approach of various authors to these interdependent relations was studied. It was concluded that although organizational strategy can be established by analyzing organization structure as well as the strong and weak aspects involved, this is not always feasible.

Full Text Available Bat species richness in Neotropical localities is generally higher than that of any other group of mammals, and surveys of local bat assemblages may provide useful data for conservation management plans. Although the bat fauna of the Rio de Janeiro state is currently one of the best known in Brazil, there are several localities not adequately surveyed yet, and most of them are in the mountainous regions and in the northern portion of the state. From January 2008 to November 2009, we conducted surveys of bats in three localities in the state of Rio de Janeiro (municipalities of Varre-Sai, Sumidouro, and Cantagalo, and our fieldwork constitutes the first assessment of the bat assemblages of these localities. Surveys were conducted using mist nets in four different habitat types in each locality (forest interior, forest edge, riparian forest, and open areas [pastures]. We captured a total of 148 individuals in 17 species, 14 genera and 3 families. Among them, 11 species were recorded in Sumidouro, seven in Cantagalo, and nine in Varre-Sai. Although species richness was low compared with previous surveys in other close localities, we recorded species that have been rarely sampled in Southeastern Brazil (e.g., Macrophyllum macrophyllum [Phyllostomidae]. The results reinforce the importance of sampling different habitats in short surveys to improve the number of species registered.

The period of supply analysis was from 1999 to 2009, and of utilization was from 2008 to October 2012.Results: Since 1999 there is a growth of hemodynamic equipment purchase. The private sector concentrates most of the supply, but it has been reducing its availability to SUS. The rate between population and equipment in Brazil exceeds the ones of some rich countries. In the sense of supply, there are in 2009, a supply rate of 1,4 equipments for 1 million inhabitants in RJ state, larger than brazilian rate, of 3,4 but the rates are similar for public customers.Conclusion: Interventional cardiology procedures have improved in the state, but in a different way. And this is because the public hospitals at Rio de Janeiro have mostly reduced their production, while the private ones have increased their production. The observed result is the SUS users performing their procedures at great distances.

A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

Full Text Available Horn fly resistance to pyrethroid insecticides occurs throughout Brazil, but knowledge about the involved mechanisms is still in an incipient stage. This survey was aimed to identify the mechanisms of horn fly resistance to cypermethrin in Mato Grosso do Sul state, Brazil. Impregnated filter paper bioassays using cypermethrin, synergized or not with piperonyl butoxide (PBO and triphenyl phosphate (TPP, were conducted from March 2004 to June 2005 in horn fly populations (n = 33 from all over the state. All populations were highly resistant to cypermethrin, with resistance factors (RF ranging from 89.4 to 1,020.6. Polymerase chain reaction (PCR assays to detect the knockdown resistance (kdr mutation also were performed in 16 samples. The kdr mutation was found in 75% of the tested populations, mostly with relatively low frequencies (<20%, and was absent in some highly resistant populations. Addition of TPP did not significantly reduce the LC50 in any population. However, PBO reduced LC50s above 40-fold in all tested populations, resulting in RFs ≤ 10 in most cases. Horn fly resistance to cypermethrin is widespread in the state, being primarily caused by an enhanced activity of P450 mono-oxygenases and secondarily by reduced target site sensitivity.

Full Text Available Objetivo: analisar a relação entre estrutura de capital e governança corporativa. Método: a amostra reúne as empresas listadas na BM&FBOVESPA no período de 2010 a 2014. Os dados foram coletados no website do BNDES e na base Economática® e a análise quantitativa foi realizada por meio de teste de diferenças entre médias, análise de correlação e regressão linear múltipla. Resultados: as empresas não participantes dos níveis diferenciados de governança corporativa apresentam maior endividamento médio. No ano de 2012, as empresas receberam maior volume de recursos financiados pelo BNDES, destacando- se a empresa Petrobras. Os resultados apontam que a governança corporativa influenciou negativamente o endividamento subsidiado, e que a rentabilidade apresentou uma relação negativa com todos os quatro tipos de endividamento analisados, confirmando-se no mercado brasileiro o que preceitua a Teoria Pecking Order. Contribuições: A pesquisa contribui para enriquecer a bibliografia sobre estrutura de capital, ao incorporar a dívida subsidiada como uma das variáveis explicativas do modelo. Devido à sua grande importância para o meio empresarial, e ao fato de os resultados dos estudos acadêmicos serem, em linhas gerais, heterogêneos, as discussões sobre estrutura de capital contribuem de alguma forma para o avanço nesse campo de pesquisa.

Full Text Available A suposição cognitivista de que a consciência de um "esquema argumentativo" oriente as produções textuais dos indivíduos está longe de ser pacífica. Alternativamente, sugere-se que os elementos incluídos num texto seriam determinados pela consciência a respeito de parâmetros da situação de produção textual (finalidade, destinatário, etc.. Partindo-se desta controvérsia, investigou-se em que medida a reflexão sobre a "estrutura argumentativa" exerceria um impacto sobre os elementos que crianças e adultos jovens incorporariam a seus textos. A análise dos resultados mostrou que: ponto de vista e justificativa foram os elementos considerados indispensáveis a uma escrita argumentativa. Antecipação de contra-argumentos foi vista como relevante para a consecução do objetivo persuasivo do texto apenas quando eram rebatidos. A reflexão sobre elementos da "estrutura argumentativa" nem sempre correspondeu à inclusão destes nos textos produzidos. Tal inclusão dependeu primordialmente da avaliação dos elementos que mais contribuiriam para a consecução da finalidade persuasiva do texto - consciência retórica.

Full Text Available Este estudo objetivou avaliar a associação entre a saúde mental e o nível de estruturação da vida ocupacional entre ex-bancários que viveram uma longa experiência de indefinição dos seus vínculos empregatícios em decorrência da liquidação do banco de economia no qual trabalhavam. Aplicaram-se, em uma amostra de 101 ex-bancários, alguns questionários estruturados. Os resultados revelaram três estilos de estruturação da vida ocupacional (estruturação pelo controle racional, pelo conformismo compensatório e pela crença no crescimento, a variação do nível de estruturação e a variação dos níveis de deterioração da saúde mental. A aplicação da ANOVA revelou que o grupo que apresenta o estilo de estruturação pelo conformismo compensatório tende a apresentar mais deterioração da saúde mental. A aplicação de análise de regressão mostrou, por sua vez, que o escore em deterioração em saúde mental e outros aspectos sociodemográficos oferecem previsibilidade ao nível de estruturação

Rosembergue Valverde

Full Text Available Resumo O objetivo deste artigo é avaliar a capacidade da economia brasileira de sustentar taxas de crescimento em longo prazo, considerando as complementaridades técnicas intersetoriais como vetor de absorção e difusão tecnológicas na estrutura industrial. Para realizar essa tarefa, recorre-se às teorias neo-schumpeteriana, que descrevem os processos de absorção e difusão tecnológicas e à construção de um modelo de crescimento multissetorial de inspiração neorricardiana do tipo Sraffa-Von Neumann. Em acordo com os procedimentos metodológicos adotados, identificam-se descontinuidades produtivas, características de estrangulamentos da produção, que comprometem as condições de crescimento de longo prazo e os processos de absorção e difusão tecnológicas da economia brasileira. Em conclusão, destaca-se a existência de pontos de estrangulamentos de produção em setores com elevado grau de basicidade, fundamentais para a reprodução da estrutura produtiva da economia brasileira.

Shaded relief of Bahia State, Brazil

Science.gov (United States)

2000-01-01

This topographic image is the first to show the full 240-kilometer-wide (150 mile)swath collected by the Shuttle Radar Topography Mission (SRTM). The area shown is in the state of Bahia in Brazil. The semi-circular mountains along the left side of the image are the Serra Da Jacobin, which rise to 1100 meters (3600 feet) above sea level. The total relief shown is approximately 800 meters (2600 feet). The top part of the image is the Sertao, a semi-arid region, that is subject to severe droughts during El Nino events. A small portion of the San Francisco River, the longest river (1609 kilometers or 1000 miles) entirely within Brazil, cuts across the upper right corner of the image. This river is a major source of water for irrigation and hydroelectric power. Mapping such regions will allow scientists to better understand the relationships between flooding cycles, drought and human influences on ecosystems.This shaded relief image was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from green at the lowest elevations to reddish at the highest elevations. Shaded relief maps are commonly used in applications such as geologic mapping and land use planning.The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission is designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging

Enzootic bovine leucosis (EBL) is a silent disease caused by a retrovirus [bovine leukaemia virus (BLV)]. BLV is classified into almost 10 genotypes that are distributed in several countries. The present research aimed to describe two BLV gp51 env sequences of strains detected in the state of São Paulo, Brazil and perform a phylogenetic analysis to compare them to other BLV gp51 env sequences of strains around the world. Two bovines from different herds were admitted to the Bovine and Small Ruminant Hospital, School of Veterinary Medicine and Animal Science, University of São Paulo, Brazil. In both, lymphosarcoma was detected and the presence of BLV was confirmed by nested PCR. The neighbour-joining algorithm distance method was used to genotype the BLV sequences by phylogenetic reconstruction, and the maximum likelihood method was used for the phylogenetic reconstruction. The phylogeny estimates were calculated by performing 1000 bootstrap replicates. Analysis of the partial envelope glycoprotein (env) gene sequences from two isolates (25 and 31) revealed two different genotypes of BLV. Isolate 25 clustered with ten genotype 6 isolates from Brazil, Argentina, Thailand and Paraguay. On the other hand, isolate 31 clustered with two genotype 5 isolates (one was also from São Paulo and one was from Costa Rica). The detected genotypes corroborate the results of previous studies conducted in the state of São Paulo, Brazil. The prediction of amino acids showed substitutions, particularly between positions 136 and 150 in 11 out of 13 sequences analysed, including sequences from GenBank. BLV is still important in Brazil and this research should be continued.

Brazil: anchoring the region

Costamilan, L.C.L.

1997-01-01

The role of Brazil's state-run petroleum company, Petrobras, in providing a national supply of oil and natural gas and their products to Brazil was discussed. Petrobras is the sole state-run enterprise which carries out research, exploration, production, refining, imports, exports and the transportation of oil and gas in Brazil. Petrobras has built a complete and modern infrastructure made up of refineries, distribution bases, terminals and oil and gas pipelines. Recently (1995) the Brazilian National Assembly approved legislation that while confirming the state monopoly, also provides private contractors and other state-owned companies ways to participate in the petroleum sector. There exists a great potential for oil and gas in many of Brazil's 29 sedimentary basins. The regulatory legislation also created two new organs to deal with the partial deregulation of the petroleum sector, the National Board for Energy Policy and the National Petroleum Agency. The first of these will deal with policy issues, measures and guidelines regarding regional energy supply and demand and specific programs such as those affecting natural gas, fuel alcohol, coal and nuclear energy. The National Petroleum Agency will manage the hydrocarbon sector on behalf of the government. Its functions will include regulation and monitoring of the sector, managing the bidding process for concessions for exploration and production, and other related activities. The new legislation opens up new horizons for the Brazilian oil sector, providing opportunities for private investment, both domestic and foreign, as well as for new technological capabilities associated with these investments. 1 tab., 6 figs

2015-12-01

Full Text Available Abstract This paper uses the framework of the Copenhagen School to understand the process of securitization of cyberspace, exploring how something in such sphere becomes a threat. Seeking to contribute to the debate, this study analyses the securitization discourses of Brazil and of the United States from Hansen and Nissenbaum's (2009 theorization about the existence of a specific sector for cybersecurity. To comprehend the securitization of cyberspace in these terms allows not only to identify distinct levels of securitization, but also to capture the dynamics of cyber threats, distinguishing them from those existent in other sectors, as well as to trace distinctions between tendencies of securitization and militarization.

Full Text Available Dadas as configurações da indústria e os grupos estratégicos, diferentes estratégias são requeridas por parte das empresas para responder à estrutura de mercado. Especialmente ao se considerar oligopólios competitivos, muitos estudos focam nas grandes empresas do núcleo desses setores. Entende-se que a compreensão das estratégias das firmas que atuam às margens das grandes oligopolistas, ou seja, na “franja” desses mercados, também é relevante, pois a escolha estratégica e o desempenho das empresas na “franja” interferem na dinâmica de todo o setor. Com base no paradigma Estrutura-Conduta-Desempenho da Organização Industrial, o presente trabalho tem por objetivo revelar como as estratégias das firmas na “franja” estão alinhadas à estrutura de mercado de baterias automotivas para reposição. Para tanto, foi realizada pesquisa qualitativa descritiva, por meio de entrevistas semiestruturadas com diretores de quatro firmas fabricantes de baterias para reposição. Os resultados apontam para a importância da estrutura da indústria nesse mercado. Além da necessidade de estratégias não preço para dar suporte a concorrência por preço, típica de empresas na “franja” de oligopólios competitivos, observa-se uma combinação de diferentes estratégias, indicando grande complexidade na definição de estratégias. Assim, a concorrência por preço é suportada, em grande parte, por estratégias de não preço, tais como de inovação e de qualidade. Ademais, a regulação ambiental tem importante papel nas condições de base da oferta e na conduta das empresas, o que indica novas possibilidade de concorrência e desempenho nesse setor.

Este artigo tem por objetivo analisar se o tamanho da empresa no Brasil é uma característica importante para explicar uma outra dimensão da relação risco versus retorno: a volatilidade. Como metodologia, procedeu-se a uma reestruturação completa do índice IBrX da Bolsa de Valores de São Paulo (Bovespa, obtendo-se dois novos índices: um de empresas com grande porte e outro de empresas com pequeno porte. A partir dos índices construídos, analisaram-se o comportamento e a estrutura a termo da volatilidade, com ajustes dos modelos GARCH (1,1 e TARCH (1,1. Em linhas gerais, pode-se concluir que o comportamento e a estrutura a termo da volatilidade de empresas de grande e pequeno porte são diferentes, o que permite a incorporação da característica tamanho da empresa nas funções financeiras, tais como decisões de investimentos, precificação de títulos e gerenciamento de risco.Recent finance literature states that certain company characteristics are relevant to explain the returns expected, which is contrary to classic financial models such as the Capital Asset Pricing Model.

Full Text Available In goat and sheep flocks, mycoplasmosis is a disease that may cause severe economical losses associated with polyarthritis, mastitis, agalactia, conjunctivitis, pneumonia and reproductive failure. The latter may involve repeat breeding, granular vulvovaginitis, infertility and abortions. The aim of the present study was to assess the occurrence of Mycoplasma agalactiae (Ma in semen and milk samples from naturally infected goat in the semiarid region from Pernambuco State, Northeast from Brazil. Thirty-nine semen samples and 81 milk samples were submitted to DNA extraction using a commercially available kit and following the manufacturer's instructions. The polymerase chain reaction (PCR was then performed in accordance with protocols described in the literature. The results of the present study revealed the presence of Ma in the DNA of 17.9% (7/39 of the semen samples and 3.7% (3/81 of the milk samples. The results obtained in the present study confirm the elimination of the DNA of Ma in the semen and milk samples. The presence of this agent in goat flocks is considered very risky in terms of reproductive disorders and contagious agalactia outbreaks in the Northeast region of Brazil.

Health and innovation: economic dynamics and Welfare State in Brazil

Directory of Open Access Journals (Sweden)

Carlos Augusto Grabois Gadelha

Full Text Available Abstract: The effective enforcement of the access to healthcare as fundamental right requires an important theoretical and political effort at linking the often contradictory economic and social dimensions of development. This study suggests the need for a systemic view of policies related to the industrial base and innovation in health and the construction of the Brazilian Unified National Health System (SUS. The authors investigate the relations between health, innovation, and development, seeking to show and update the political, economic, and social determinants of the recent Brazilian experience with the Health Economic-Industrial Complex (HEIC. They discuss how the agenda for innovation and domestic industrial production in health gained a central place in the project for construction of the SUS. The article thus seeks to link inherent issues from the agenda for development, production, and innovation to social policy in healthcare, as observed in recent years, and based on this analysis, points to political and conceptual challenges for implementing the SUS, especially as regards strengthening its technological and industrial base. As a byproduct, the article develops an analytical and factual focus on the consolidation of the HEIC in Brazil, both as a dynamic vector of industrial development, generating investment, income, employment, and innovations, and as a decisive element for reducing vulnerability and structural dependence in health. The authors aim to show that strengthening the SUS and orienting it to social needs is an essential part of building a social Welfare State in Brazil.

Abstract Rhodnius marabaensis sp. n. was collected on 12 May 2014 in the Murumurú Environmental Reserve in the city of Marabá, Pará State, Brazil. This study was based on previous consultation of morphological descriptions of 19 Rhodnius species and compared to the identification key for the genus Rhodnius. The examination included specimens from 18 Rhodnius species held in the Brazilian National and International Triatomine Taxonomy Reference Laboratory in the Oswaldo Cruz Institute in Rio de Janeiro, Brazil. The morphological characteristics of the head, thorax, abdomen, genitalia, and eggs have been determined. Rhodnius prolixus and Rhodnius robustus were examined in more detail because the BLAST analysis of a cyt-b sequence shows they are closely related to the new species, which also occurs in the northern region of Brazil. The most notable morphological features that distinguish Rhodnius marabaensis sp. n. are the keel-shaped apex of the head, the length of the second segment of the antennae, the shapes of the prosternum, mesosternum and metasternum, the set of spots on the abdomen, the male genitalia, the posterior and ventral surfaces of the external female genitalia, and the morphological characteristics of the eggs. Rhodnius jacundaensis Serra, Serra & Von Atzingen (1980) nomen nudum specimens deposited at the Maraba Cultural Center Foundation - MCCF were examined and considered as a synonym of Rhodnius marabaensis sp. n.

Intense mining activities in Minas Gerais State - Brazil bring out tons of waste to the environment. Considerable concentrations of toxic elements penetrate the soil, ground waters and rivers. This endangers the environment quality not only in the surrounding areas but also occurs in ichthyofauna and in more distant areas of cattle raising and agricultural activities. After seasonal floods, veterinary clinic studies have shown that most animals raised in this region are affected by symptomatologic a nervous disease, still not clearly diagnosed, that suggests intoxication. These pathologies are mostly noted after floods. Instrumental Neutron Activation Analysis and was applied to determine several elements in environmental samples. The irradiation characteristics are chosen to determine the isotopes in the best conditions. In this work the INAA, was applied using the TRIGA Mark I IPR - R1 (CDTN/CNEN).. The obtained results show that the contaminated water, sediment and forage with heavy metals and toxic elements from the Das Velhas River upstream basin, the mining region, carry contamination to the ichthyofauna and farming region within a distance of approximately 400 km.

Schistosomiasis control in Brazil

Katz Naftale

1998-01-01

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.

It shows the local medicinal uses of biodiversity in Brazil's Amazonian littoral, promoting the value of folk knowledge, and its applicability in future studies. To demonstrate the importance of the knowledge of medicinal plants in the Amazonian coastal community of Marudá, located in Pará State, Brazil. Fieldwork was conducted between 1996 and 1998, using the methods of participant observation, semi-structured interviews and informal discussions to elicit information from community residents and plant specialists, in addition to collecting plant material. Community residents possess knowledge of 229 medicinal plants distributed in 81 botanical families and know how to manipulate them in a variety of ways, with special care taken to ensure that they are used in the safest and most efficient manner. Therapeutic indications for these plants include illness and disease recognized in the repertoire of Western medicine as well as ailments perceived from a local cultural perspective. Results from this study attest to informants' knowledge of medicinal flora and their ability and openness to integrate new species from diverse origins into their gamut of medicinal knowledge, including industrial therapeutic preparations and animal products. Local uses of biodiversity in Brazil's Amazonian littoral are also evinced, promoting the value of folk medicinal knowledge. Similarly, it mentions the potential of implementing local knowledge in Brazil's Unitary Health System.

American tegumentary leishmaniasis is endemic in the State of Paraná, with 99.3% of the cases reported in the South of Brazil. Spatial distribution of the disease in northern Paraná was verified, identifying the most relevant geographic areas in epidemiological terms. The study used data recorded on epidemiological forms from the Teaching and Research Clinical Test Laboratory of the State University in Maringá, from 1987 to 2004. The study only included individuals that were infected in the municipalities (counties) in northern Paraná. Identification of the epidemiological units (poles and circuits) was based on spatial density of cases, according to the model proposed by the National Health Foundation, considering the most likely infection sites. Considering 1,933 reported cases, 1,611 were infected in northern Paraná. American tegumentary leishmaniasis distribution in Paraná State suggests two circuits for production of the disease: Paraná-Paranapanema, highlighting the Cinzas-Laranjinha, Tibagi, Ivaí-Pirapó, Piquiri, and Baixo Iguaçu poles, and Ribeira, highlighting the Alto Ribeira pole.

Full Text Available Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii that affects homeothermic animals, including humans. Felines are considered the definitive host of this parasite, while other animals act as intermediate hosts. The purpose of this study was to assess the frequency of anti-T. gondii IgG antibodies in bovines in the state of Pernambuco, Brazil. Serum samples (n = 427 from animals in 13 municipalities of the coastal forest/plantation region of the state were analyzed using the immunofluorescent antibody test (IFAT. The overall results revealed a prevalence rate of 16.63% (27/427. High percentages of positivity were found among animals aged 25 to 36 months (28.57%; 30/42 and in males (22.22%; 2/9. The present findings suggest that bovine toxoplasmosis is endemic in the area under study.

Aims The objective of this paper is to perform a cross-cultural comparison of gambling disorder (GD) due to electronic gaming machines (EGM), a form of gambling that may have a high addictive potential. Our goal is to investigate two treatment-seeking samples of adults collected in Brazil and the United States, countries with different socio-cultural backgrounds. This comparison may lead to a better understanding of cultural influences on GD. Methods The total studied sample involved 733 treatment-seeking subjects: 353 men and 380 women (average age = 45.80, standard deviation ±10.9). The Brazilian sample had 517 individuals and the American sample 216. Subjects were recruited by analogous strategies. Results We found that the Brazilian sample was younger, predominantly male, less likely to be Caucasian, more likely to be partnered, had a faster progression from recreational gambling to GD, and were more likely to endorse chasing losses. Conclusion This study demonstrated that there are significant differences between treatment-seeking samples of adults presenting GD due to EGM in Brazil and in the United States. These findings suggest that cultural aspects may have a relevant role in GD due to EGM. PMID:26474662

The Poisoned Chalice: Oil and Macroeconomics in Brazil (1967-2003)

Science.gov (United States)

Biasetto, Bruno Henz

This dissertation analyzes the development of the Brazilian oil industry and its impact on the economic development of Brazil from the beginning of the "Brazilian Miracle" (1968-1973) to the end of the Fernando Henrique Cardoso's second term as president (1995-2002). The dissertation explores the closely intertwined nature of Brazil's oil industry and its macroeconomic development, shedding new light on the history of Petrobras (the Brazilian state oil company), and on other key topics of Brazilian economic history, including the Debt Crisis of the 1980s and the role of neoliberalism in Brazil. The argument is that oil policy shaped the national economy and the Brazilian state in this period. Attention to the oil industry, and to Petrobras in particular, was crucial to the establishment of diplomatic and economic policy, and to conflict within the Brazilian state. Finally, this dissertation seeks to illuminate Brazil's place in the global oil industry and how that has shaped Brazil's global economic standing.

Full Text Available The influence of sedimentation and turbidity caused by the pluviometric precipitation and by the Paraiba do Sul River during the summer was investigated on an artificial reef along the north coast of Rio de Janeiro, Brazil. Four recruitment and four cumulative plates were removed monthly (January 2002 to February 2003 from the external surface of the concrete reef modules. Empty space was not a limiting factor the recruitment. Turnover rate and structural difference index were higher in the first months and reflected low change in the species dominance during almost the entire study period. The high correlation between the precipitation and the empty space suggested that rain influence the recruitment and the succession. The recruitment was possible despite stress factors such as sedimentation, turbidity, abrasion, strong bottom currents and a lack of natural consolidated substrate. Changes in the community structure reflected the substrate colonization history of a few resistant species and their subsequent interactions.A influência da sedimentação e da turbidez causadas pela precipitação pluviométrica e vazão do rio Paraíba do Sul nos meses de verão foi investigada em um recife artificial na costa norte do Estado do Rio de Janeiro, Brasil. Quatro placas de recrutamento e quarto placas de sucessão eram retiradas mensalmente (Janeiro de 2002 a Fevereiro de 2003 da superfície externa de módulos recifais de concreto. Espaço vazio não foi um fator limitante para o recrutamento. A taxa de substituição de espécies e o grau de diferença na estrutura da comunidade foram superiores nos meses iniciais, refletindo as reduzidas mudanças na dominância das espécies durante o período de estudo. A alta correlação entre precipitação e espaço vazio sugere a influência da precipitação no recrutamento e sucessão dos organismos. Recrutamento foi possível mesmo com fatores estressantes como sedimentação, turbidez, correntes de fundo

Preterm birth is a serious public health problem, as it is linked to high rates of neonatal and child morbidity and mortality. The prevalence of premature births has increased worldwide, with regional differences. The objective of this study was to analyze the trend of preterm births in the state of Paraná, Brazil, according to Macro-regional and Regional Health Offices (RHOs). This is an ecological time series study using preterm births records from the national live birth registry system of Brazil's National Health Service - Live Birth Information System (Sinasc), for residents of the state of Paraná, Brazil, between 2000 and 2013. The preterm birth rates was calculated on a yearly basis and grouped into three-year periods (2000-2002, 2003-2005, 2006-2008, 2009-2011) and one two-year period (2012-2013), according to gestational age and mother's Regional Health Office of residence. The polynomial regression model was used for trend analysis. The predominance of preterm birth rate increased from 6.8 % in 2000 to 10.5 % in 2013, with an average increase of 0.20 % per year (r(2) = 0.89), and a greater share of moderate preterm births (32 to rate of prematurity and average annual growth during that period (7.55 % and 0.35 %, respectively). The trend analysis of preterm birth rates according to RHO showed a growing trend for almost all RHOs - except for the 7(th) RHO where a declining trend was observed (-0.95 a year); and in the 20(th), 21(st) and 22(nd) RHOs which remained unchanged. In the last three-year of the study period (2011-2013), no RHO showed preterm birth rates below 7.3 % or prevalence of moderate preterm birth below 9.4 %. The results show an increase in preterm births with differences among Macro-regional and RHOs, which indicate the need to improve actions during the prenatal period according to the specificities of each region.

Cristina Dotta Ortega

Full Text Available Partindo da constatação de que os princípios e os métodos para construção e gestão dos sistemas documentários são dispersos e carecem de sistematização, este artigo levanta a hipótese de que a noção de estrutura, ao pressupor relações mútuas entre os seus elementos, confere maior organicidade aos sistemas e garante maior qualidade e consistência na recuperação da informação frente às questões dos usuários. Desse modo, objetiva explorar fundamentos, a partir da noção de estrutura, dos registros de informação e dos sistemas documentários. Para tanto, são apresentados conceitos básicos e questões relativas aos sistemas documentários e aos registros de informação. Posteriormente, elenca aportes teóricos sobre a noção de estrutura, tratados por Benveniste, Ferrater Mora, Hjelmslev, Lévi-Strauss, Lopes, Peñalver Simó, Saussure, além de Ducrot, Fávero e Koch, para então tratar das apropriações já realizadas pela Documentação por Paul Otlet, García Gutiérrez e Moreiro González. Conclui-se que a noção de estrutura adotada para tornar explícita uma hipótese de sistematização do real, a partir de um modelo, assegura maior organicidade aos sistemas, bem como confere referência pedagógica ao fazer documentário.

A pesquisa se caracteriza como histórico-empírica na medida em que busca na história a contextualização da atual estrutura fundiária e, como estatística, uma vez que estima a relação entre indicadores de desenvolvimento humano e de estrutura fundiária. Para tanto, calcula-se a correlação e ajustam-se regressões múltiplas entre indicadores de estrutura fundiária e de desenvolvimento humano. Um dos resultados encontrados é que as microrregiões com estrutura fundiária maisdesigual possuem piores indicadores de expectativa de vida ao nascer.Abstract From the perspective of Amartya Sen´s development as expansion of human capabilities, the article tests the hypothesis that the concentration land may be a factor harmful to human development in Rio Grande do Sul. The research is characterized as historic-empirical in so far as seeking in history the contextualization of the current land structure and statistical once estimates the relationship between indicators of human development and land structure. To this end, it is estimated the correlation and adjusted multiple regressions between indicators of land structure and human development. One of the results is that the microregions with a land structure more unequal have worst indicators of life expectancy at birth.

1995-12-01

Full Text Available Mortality from asthma has shown important variations over time in several countries. In Brazil, a mortality study performed in the 60s, covering the cities of S.Paulo and Ribeirão Preto, and other ten cities showed that S.Paulo presented the lowest death rate from asthma among of them all. It was decided to study the time trends of deaths from asthma and from the whole set of respiratory diseases from 1970 to 1992, in the population aged 15-34 yrs. old in the State of S.Paulo, as well as to compare them with those of other countries. Asthma mortality rates during the 23 years of observation since 1975, showed an oscillatory declining pattern with a peak of deaths in the initial years. The linearization of the curve allows the calculation of Pearson's correlation coefficient that was significantly negative, suggesting a decline in the mortality over this period, mainly in the 5-9 yrs. old and 30-34 yrs. old strata. The segmentation of data between the period of ICD-9, 1970 to 1978, and of ICD-9, 1979 and subsequent years, shows that there is stability within each period, in all age-groups, except for that of 5-9 yr. olds between 1970-1978. Comparing the rates of the population aged 15-34 yrs. old for the State of S. Paulo, Brazil, with trends observed in 14 other countries, an intermediate pattern for the first triennial period (1970-1972 as well as for the subsequent triennial periods, emerges. A prevalence study of asthma, a follow up program meant for using emergency rooms and a surveillance of deaths due to all respiratory diseases and specifically to asthma are strongly recommended.

Coccidioidomycosis, a fungal illness acquired by the inhalation of arthroconidia of Coccidioides sp., was first described in 1894. Coccidioidomycosis is mainly restricted to areas with arid climate, alkaline soil and low rainfall. Consequently, most of the reported cases in Brazil have occurred in the northeastern region. We report three cases of pulmonary coccidioidomycosis occurring between 2005 and 2006 in an endemic area in the state of Ceará, Brazil. The three patients were immunocompetent adult males, hunters of armadillos (Dasypus novemcinctus), with complaints of cough, fever, dyspnea and pleuritic pain. All three patients presented pulmonary involvement, and only one also presented cutaneous lesions. Chest X-rays and CT scans of the patients revealed characteristic coccidioidomycosis lesions. The diagnosis was confirmed by serological testing. All of the patients evolved to cure after antifungal treatment.

Originality/gap/relevance/implications: The study contributes to the literature by examining the financial capital structure of emerging market companies in a context of crisis, in addition to using a robust econometric tool – the quantile regression. Key methodological aspects: In this work, the quantile regression was used as an analysis tool, and this technique allowed to observe the impacts of the crisis not only in the average level of indebtedness of companies, but also in its extreme values. Therefore, this work is characterized as descriptive, and the analyzed relations are quantitative. Firms were analyzed in Brazil, Russia, India and China. Summary of key results: The results indicate financing strategies, according to the theories of Pecking Order and Trade-off as regards to the level of debt. Key considerations/conclusions: The survey concluded that firms have different financing strategies even in the same country. Thus, the financial performance of firms would be influenced by economic conditions in the country, as well as the existing debt level in each company.

Considering the importance of Brazil's Information System on Public Health Budgets (SIOPS) as a tool for planning, management, and social control of public expenditures in health, this article aimed to evaluate the relationship between the regularity of data entry into the SIOPS and knowledge and use of the system by municipal health administrators in Pernambuco State, Brazil. Ten municipalities were selected from the State's five meso-regions, five of which entered information into the system and five only on an irregular basis. Semi-structured interviews were performed with the municipal health secretaries. Analysis of the data showed that command of information technology and knowledge of the System do not affect the regularity of data entry, as a function of the distance between the Municipal Health Secretariat administrators and the SIOPS, such that the data are normally entered by outsourced services. Thus, the resulting information has not been fully explored by systems administrators as a management tool.

The growth and nutritional status of 185 school-aged children (97 boys and 88 girls) of low socio-economic level in Nova Iguaçú, State of Rio de Janeiro, Brazil, were studied. Nutritional anthropometry identified 3.52 and 6.25% of the children as suffering from wasting and stunting, respectively. These prevalences of malnutrition were comparable to those described in pre-school children living in a "favela" (shanty town) of Rio de Janeiro. In general, the median height fell below the 25th centile of the international standard of growth. The value of 10 year-old boys fell below the 10th centile. The mean values of weight and height of these children were comparable to those of children from the Northeastern region of Brazil ("Nordeste"), higher than those found for children in the State of Paraíba, Brazil, and lower than those for middle-class children of the State of S. Paulo. Skinfold thickness, arm circumference, and arm fat area data were higher in girls than boys. However, arm muscle are values in boys were superior in comparison to those of girls.

The present study aimed to analyse the official epidemiological data on salmonelloses occurred in the State of RS, during the period of 2002 to 2004. Even though data on recent salmonelloses were available, only data concerning the period comprising in 2002 to 2004 were analysed because the official worksheet records presented more consistent information about the salmonellosis outbreaks. Results indicated that, among the 624 foodborne outbreaks officially investigated, 202 (32.37% were confirmed as salmonellosis. Among them 23,725 people were involved, 4,148 became sick, 1,878 were hospitalized and one person died. The season with the highest incidence of salmonelloses was spring, and the most affected age group was composed of people aged between 20 to 49 years old (56.66%. Animal origin foods -especially eggs and meat products -were very often involved with the outbreaks, however homemade mayonnaise was identified as the main food vehicle for salmonelloses (53.51%. The majority of the cases occurred inside private homes (55.81% and food services (12.1%, and the main factors contributing to the occurrence of the outbreaks were the consumption of products without sanitary inspection (26.7% and exposure of food at room temperature for more than two hours (18.58%. Similarly to what was previously reported for the period of 1997 to 2001, Salmonella spp. was the most prevalent foodborne disease agent in the State of RS during the years of 2002 to 2004.

Land-use change (LUC) in Brazil has important implications on global climate change, ecosystem services and biodiversity, and agricultural expansion plays a critical role in this process. Concerns over these issues have led to the need for estimating the magnitude and impacts associated with that, which are increasingly reported in the environmental assessment of products. Currently, there is an extensive debate on which methods are more appropriate for estimating LUC and related emissions and regionalized estimates are lacking for Brazil, which is a world leader in agricultural production (e.g. food, fibres and bioenergy). We developed a method for estimating scenarios of past 20-year LUC and derived CO 2 emission rates associated with 64 crops, pasture and forestry in Brazil as whole and in each of its 27 states, based on time-series statistics and in accordance with most used carbon-footprinting standards. The scenarios adopted provide a range between minimum and maximum rates of CO 2 emissions from LUC according to different possibilities of land-use transitions, which can have large impacts in the results. Specificities of Brazil, like multiple cropping and highly heterogeneous carbon stocks, are also addressed. The highest CO 2 emission rates are observed in the Amazon biome states and crops with the highest rates are those that have undergone expansion in this region. Some states and crops showing large agricultural areas have low emissions associated, especially in southern and eastern Brazil. Native carbon stocks and time of agricultural expansion are the most decisive factors to the patterns of emissions. Some implications on LUC estimation methods and standards and on agri-environmental policies are discussed. © 2017 John Wiley & Sons Ltd.

Full Text Available Seasonality in insect abundance in the "Cerrado" of Goiás State, Brazil. Many studies have provided evidence that tropical insects undergo seasonal changes in abundance and that this is partly due to alternation between the dry and rainy seasons. In the Brazilian "Cerrado" (savannah, this season alternation is particularly evident. The purpose of this work was to study the seasonal abundance of insects in a "Cerrado" area in the municipality of Pirenópolis, Goiás State, Brazil. The insects were captured fortnightly using a light trap between September 2005 and August 2006. The insects collected were separated at the order level and counted. Faunistic analysis was performed to select the predominant insect orders, a multiple linear regression to examine the relation between climatic variables (temperature and precipitation with the abundance of insects and a circular distribution analysis to evaluate the existence of seasonality in the abundance of insect orders. A total of 34,741 insect specimens were captured, belonging to 19 orders. The orders with the greatest number of specimens were Hymenoptera (8,022, Coleoptera (6,680, Diptera (6,394, Lepidoptera (6,223, Isoptera (2,272, Hemiptera (2,240 and Trichoptera (1,967, which represent 97.3% of all the specimens collected. All the orders, except for Diptera, Isoptera and Trichoptera, showed a relationship with the climate variables (temperature, and all the orders, except for Diptera, presented a grouped distribution, with greater abundance in the transition from the end of the dry season (September to the start of the rainy one (October/November. A discussion about seasonality on the abundance of the insects is presented.

Full Text Available No período de 1994 a 2004, a população canina de Araçatuba, São Paulo, Brasil, registrou duas importantes zoonoses: a raiva e a leishmaniose visceral. Analisaram-se as mudanças ocorridas nessa população durante esse período, utilizando resultados de censos caninos e de coletas censitárias de sangue realizados em 1994, 1999 e 2004. A relação cão/10 habitantes variou significativamente, passando de 1,7 em 1994 para 2,0 em 1999 e para 1,8 em 2004. A porcentagem de cães com até um ano de idade passou de 20% para 32,5% e o número de eutanásias realizadas também aumentou após 1999, com a introdução da leishmaniose visceral. O número de cães e a estrutura etária variaram nos diversos setores do município e aqueles com maior porcentagem de animais com até dois anos de idade apresentaram maior ocorrência de casos de leishmaniose visceral humana e canina. Tais resultados decorrem de ações de controle adotadas nos setores com casos humanos de leishmaniose visceral, porém, o aumento da população canina mais jovem pode resultar em aumento da susceptibilidade destes cães à doença, favorecendo a manutenção da mesma na área.From 1994 to 2004, the canine population in Araçatuba, São Paulo State, Brazil, suffered two major canine zoonoses: rabies and visceral leishmaniasis. Changes in the dog population during this period were evaluated using canine census data from 1994 and 2004 and the results of blood samples for diagnosis of canine visceral leishmaniasis in 1999. The ratio of dogs per 10 inhabitants varied from 1.7 in 1994 to 2.0 in 1999 and 1.8 in 2004. The percentage of puppies less than 1 year of age increased from 20% to 32.5%, and the number of euthanized dogs also increased after 1999, when visceral leishmaniasis began to appear. The number of dogs and percentage of puppies varied between different areas of the city, and neighborhoods with a higher percentage of young animals showed more cases of both human and

Total heavy metal and trace elements concentrations were evaluated in smelting waste areas, in Piracicaba River, Minas Gerais, Brazil. The studies samples were surface water, border sediment, and fish muscle (Acara - Geophagus Brasiliensis). Elevated concentrations were found in Acara muscle fish As (1.3 - 1.8 {mu}g g{sup -1}), Hg (0.7 - 1.84 {mu}g g{sup -1}), Cr (0.7 - 4.1 {mu}g g{sup -1}), Zn ( 43 - 76 {mu}g g{sup -1}); in sediment Fe (81996 - 461147 {mu}g g{sup -1}), Cr (126 - 447 {mu}g g{sup -1}), Co ( 540 - 1016 {mu}g g{sup -1}), Th (7.9 - 50 {mu}g g{sup -1}). For the water samples the similar high heavy metal concentrations of Al, As, Cr, Fe, and Zn in all sampling sites were above the maximum limits permitted by Brazilian Environmental Council. The high level of heavy metals can affect the aquatic and cattle animals and human health. To conclusion the region studied in Piracicaba River in Minas Gerais State, Brazil, is not in agreement with the environmental parameters for 'water class 3' according to Resolution by Brazilian Environmental Standards (CONAMA). An urgent program of measures for assessment and monitoring is necessary in this River. (author)

To analyze the profile of claimants and medicines demanded in lawsuits. Descriptive study that examined 827 lawsuits with 1,777 demands of access to medicines in the period between July 2005 and June 2006 in the state of Minas Gerais, Southeastern Brazil. There were examined the type of health care provided to claimants and their attorneyship. The medicines were described based on the following: drug registration at the National Health Surveillance Agency (Anvisa); wheter they were essential medicines; supply in the Brazilian Health System programs; and evidence of drug efficacy. More than 70% of the claimants were provided care in the private health system and 60.3% hired private lawyers. The most common diagnosis of claimants was rheumatoid arthritis (23.1%) and the immunosuppressant agents were the most frequent demand medicines (mainly adalimumab and etanercept). Approximately 5% of the medicines demanded were not registered at Anvisa, 19.6% were included in the Brazilian List of Essential Medicine, 24.3% were included in the High-Cost Drug Program and 53.9% showed consistent evidence of efficacy. Among the medicines that were not available in Brazilian Health System, 79.0% had therapeutic alternatives in drug programs. The phenomenon of judicialization of health in Brazil can point out failures in the public health system as some medicines demanded are included in its lists. However, it is a barrier for rational drug use and application of the National Drug Policy guidelines, especially when there are demanded medicines with no evidence of efficacy and that are not included in Brazilian Health System standards.

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.

Full Text Available A serosurvey was conducted in wild animals captured close to two areas where hantavirus cardiopulmonary syndrome (HCPS occurred in São Paulo State, Brazil. Serum samples from a total of 43 mammals were tested for antibodies reactive with Sin Nombre (SN hantavirus using a strip immunoblot assay. RNAs from the blood clots of the positive samples were submitted to reverse transcriptase-polymerase chain reaction (RT-PCR. Two rodents of the genus Oligoryzomys were positive for hantavirus antibodies. These animals were captured in the Iguape region and represented 16.7% (2/12 of the sera from rodents and 100.0% (2/2 of the Oligoryzomys captured in that area. RT-PCR failed to amplify any viral cDNA. These results are in agreement with other data that suggest that members of this genus are important reservoirs of hantaviruses in Brazil.

Full Text Available ABSTRACT We describe the diversity, natural history and structure of snake assemblages from Marajó Island, state of Pará, Brazil, after analyzing 439 specimens deposited in herpetological collections. We tested the hypothesis that snake assemblages from forest and open areas of Marajó Island are distinct with regard to their structure, composition and functional groups. To compare the snake composition of the forest and open areas of Marajó with other comparable assemblages in Brazil, Principal Coordinate Analysis and Clustering tests were performed. A total of 61 species of snakes was recorded for Marajó, with ten species cited for the first time for the study area (Atractus natans Hoogmoed & Prudente, 2003, A. schach (Boie, 1827, Dendrophidion dendrophis (Schlegel, 1837, Helicops hagmanni Roux, 1910, Hydrops martii (Wagler in Spix, 1824, Lygophis meridionalis (Schenkel, 1901, Erythrolamprus typhlus (Linnaeus, 1758, Philodryas argentea (Daudin, 1803, Siphlophis cervinus (Laurenti, 1768, and Thamnodynastes sp.. The composition and structure of snake assemblages between forested and open were different, with five functional groups of snakes in forest areas, and three groups in open areas, based on habit and habitat. In all, 19 species were exclusive to forest areas, 10 were exclusive to open areas and 26 species were recorded in both areas. Our results revealed greater richness for forested areas, probably due to greater habitat heterogeneity. The species composition for forested area in Marajó was similar to that found in other Amazonian assemblages, while that for open areas was more similar to the Pantanal region than other open area assemblages. The general structure of the snake assemblage of Marajó was dominated by anurophagous, terrestrial and diurnal species. Terrestrial, arboreal and semi-arboreal snakes showed a seasonal offspring production pattern, while the pattern for aquatic and semi-aquatic species was aseasonal. The

Full Text Available Five restriction site polymorphisms in the β-globin gene cluster (HincII-5'ε, HindIII-Gγ, HindIII-ªγ, HincII-'ψβ1 and HincII-3''ψβ1 were analyzed in three populations (n = 114 from Reconcavo Baiano, State of Bahia, Brazil. The groups included two urban populations from the towns of Cachoeira and Maragojipe and one rural Afro-descendant population, known as the "quilombo community", from Cachoeira municipality. The number of haplotypes found in the populations ranged from 10 to 13, which indicated higher diversity than in the parental populations. The haplotypes 2 (+----,3(----+,4(-+--+and6(-++-+onthe βA chromosomes were the most common, and two haplotypes, 9 (-++++and 14 (++--+, were found exclusively in the Maragojipe population. The other haplotypes (1, 5, 9, 11, 12, 13, 14 and 16 had lower frequencies. Restriction site analysis and the derived haplotypes indicated homogeneity among the populations. Thirty-two individuals with hemoglobinopathies (17 sickle cell disease, 12 HbSC disease and 3 HbCC disease were also analyzed. The haplotype frequencies of these patients differed significantly from those of the general population. In the sickle cell disease subgroup, the predominant haplotypes were BEN (Benin and CAR (Central African Republic, with frequencies of 52.9% and 32.4%, respectively. The high frequency of the BEN haplotype agreed with the historical origin of the afro-descendant population in the state of Bahia. However, this frequency differed from that of Salvador, the state capital, where the CAR and BEN haplotypes have similar frequencies, probably as a consequence of domestic slave trade and subsequent internal migrations to other regions of Brazil.

The Brazilian dietary guidelines are based in part on mainstream United States' recommendations, in spite of the criticisms and shortcomings of the American guidelines. In this paper, Brazilian food guidelines are summarized and discussed in comparison with the USA recommendations. American and Brazilian dietary recommendations are quite similar in many aspects, particularly those related to variety in the diet, the importance of physical activity and weight management. Different to American guidelines, those from Brazil advise people to choose fresh foods, to prefer healthier types of fat, to limit trans fat intake and to eat good sources of protein, but does not recommend the consumption of whole grains. Besides the challenges related to their implementation, indicators for the evaluation of the effectiveness of these guidelines should be established from the beginning, particularly those related to changes in dietary habits and the prevalence of obesity.

2014-01-01

Highlights: • Brazil holds reserves of high ash coal that can only be used in mine-mouth plants. • Water scarcity requires the use of wet or dry cooling systems in several regions. • The co-firing of 30 wt% eucalyptus is possible regarding the biomass availability. • Biomass cultivation would aggravate the water scarcity in several regions. - Abstract: Brazil has favorable edaphoclimatic conditions for the cultivation of biomass for energy. On the other hand, the country plans to expand its thermal power park using fossil fuels, including Brazil’s high ash coal. This study estimates the potential of co-firing biomass from energy forests in power plants fired with Brazilian coal in the state of Rio Grande do Sul, Brazil, focusing on the limits given by biomass and water availability. Results show that the state holds coal reserves that could support a potential of approximately 8 GW. Referring to limits due to water availability, different outcomes were found for the various coal fields in Rio Grande do Sul. The Candiota coal field, which represents the most important coal field, holding a capacity of 4 GW, shows severe restrictions for water availability that would be aggravated by intense eucalyptus cultivation

Ecology and conservation of the endemic lizard Tropidurus hygomi in “restinga” habitats of the north coast of Bahia state, Brazil

Directory of Open Access Journals (Sweden)

Karina Vieira Martins

2010-12-01

Full Text Available “Restingas” are herbaceous/ shrubby coastal sand-dune habitats that cover great areas of Brazil, particularly along the Bahia state coast. The restingas are disturbed and are under strong pressure, mainly in northeastern Brazil. Fragmentation of the landscape and habitat loss within natural ecosystems are the factors which are mainly responsible for reduction of species diversity by extinction events. The goal of thepresent study was elucidate whether the conservation status of restinga habitats on the northern coast of Bahia state was interfering with microhabitat use by the endemic lizard Tropidurus hygomi. The results showed that the use of microhabitat resources by T. hygomi did not have any signifi cant differences in the four areas we chose for study. However, diverse factors of degradation were found to contribute indirectly to its habitat loss. The T. hygomi lizard is a generalist in its use of restinga microhabitats, and probably due the endemic condition, its conservation status is linked directly to conservation of the restinga habitats on the northern coast of Bahia state.

Full Text Available Este trabalho foi desenvolvido em quatro trechos de um riacho em área de pastagem no noroeste do Estado de São Paulo, com o objetivo de examinar a composição e estrutura quantitativa da ictiofauna e investigar sua relação com as características do hábitat. Os peixes foram coletados nos três meses centrais dos períodos seco e chuvoso por meio de uma passagem de pesca elétrica por mês. A análise da qualidade química da água mostrou condições boas nos quatro trechos, enquanto que a análise da integridade física do hábitat mostrou condições pobres para os trechos 2 e 3 e regulares para os trechos 1 e 4. Foram coletadas 27 espécies de peixes, totalizando 1.241 indivíduos e 5,1 kg. A estrutura quantitativa da ictiofauna demonstrou maior associação com a estrutura do hábitat do que com a sazonalidade visto que os trechos 1 e 2 foram agrupados separadamente dos trechos 3 e 4, independentemente do período de amostragem. De acordo com a análise de correspondência canônica, a elevada abundância de Gymnotus carapo Linnaeus, 1758 nos trechos 1 e 2 esteve associada principalmente com a abundância de vegetação marginal. O maior volume de hábitat no trecho 3 explicou a abundância de Piabina argentea Reinhardt, 1867, e a predominância de substratos rochosos no trecho 4 explicaram a abundância de Hypostomus nigromaculatus (Schubart, 1964.Four stream stretches (sites 1-4 in a pasture area of the northwestern São Paulo state were studied, aiming to examine the composition and quantitative structure of the ichthyofauna and investigate its relation with habitat features. Fishes were collected during the three most representative months of the dry and wet periods by one electrofishing pass in each month. Chemical water quality analysis showed good conditions in all sites, whereas physical habitat integrity analysis showed poor conditions to the sites 2 and 3 and fair to the sites 1 and 4.

Detection of gross alpha and beta radioactivity is important for a quick surveying of both natural and anthropogenic radioactivity in water. Furthermore, gross alpha and gross beta parameters are included in Brazilian legislation on quality of drinking water. In this work, a low background liquid scintillation spectrometer was used to simultaneously determine gross alpha and gross beta in samples of the public water supplies in the state of Goias, Brazil, during 2010-2015. Sample preparation involved evaporation to concentrate the sample ten-fold. The results indicate that the water meets the radioactivity standards required by the regulations MS 2914/2011 of the Brazilian Department of Health. Concerning the high level of censored observations, a statistical treatment of data was conducted by using analysis methods of censored data to provide a reference value of the gross alpha and beta radioactivity in drinking water from the state of Goias. The estimated typical activities are very low, 0.030 Bq•L{sup -1} and 0.058 Bq•L{sup -1}, respectively. (author)

This study seeks to evaluate dental care coverage in the State Military Police in Salvador, Bahia State, Brazil, from 2002 to 2004, estimating potential and real coverage rates. A single descriptive study was performed. Calculations were made of potential coverage rates considering hourly workloads of staff dentists and the real rates resulting from actual outpatient treatment. Potential human resources coverage was adequate (1 dentist per 1,618 policemen), while the real coverage rate was considered below the standard proposed by the Brazilian Ministry of Health (0.39 procedures per policeman per year). The low real coverage rate could be related to low productivity, the reasons for which should be investigated in greater depth in future studies, and might include organizational problems and lack of a management system to improve the quality of professional practice, with specifically defined targets.

Full Text Available Seasonal changes of the phytoplanktonic community and limnological abiotic characteristics of Caçó pond (Maranhão State, Brazil was evaluated from two field researches during the rainy (April 1999 and dry (November 1999 seasons. Measurements of twelve chemical and physical variables and phytoplankton collections were carried out at eight sampling stations. The Chlorophyceae and Cyanobacteria groups were in highest fractions during the rainy and dry seasons, respectively. The limnological abiotic variables showed a homogenous spatial distribution. The cluster analysis, using Bray-Curtis distance, distinguished two major groups, represented by the most common and abundant species in both the periods. The results showed that the climate regime, due to the seasonal changes in pluviosity, was a determinant over the phytoplanktonic community structure at Caçó pond.Mudanças sazonais na comunidade fitoplanctônica e nas características limnológicas abióticas da lagoa do Caçó, Estado do Maranhão, Brasil, foram avaliadas a partir de duas coletas, nos períodos de chuva (Abril/1999 e seca (Novembro/1999.

Brazil nut tree (Bertholletia excelsa) is native of the Amazon rainforest. Brazil nuts are consumed worldwide and are known as the richest food source of selenium (Se). Yet, the reasoning for such Se contents is not well stablished. We evaluated the variation in Se concentration of Brazil nuts from Brazilian Amazon basin, as well as soil properties, including total Se concentration, of the soils sampled directly underneath the trees crown, aiming to investigate which soil properties influence Se accumulation in the nuts. The median Se concentration in Brazil nuts varied from 2.07 mg kg - 1 (in Mato Grosso state) to 68.15 mg kg - 1 (in Amazonas state). Therefore, depending on its origin, a single Brazil nut could provide from 11% (in the Mato Grosso state) up to 288% (in the Amazonas state) of the daily Se requirement for an adult man (70 μg). The total Se concentration in the soil also varied considerably, ranging from Brazil nuts generally increased in soils with higher total Se content, but decreased under acidic conditions in the soil. This indicates that, besides total soil Se concentration, soil acidity plays a major role in Se uptake by Brazil nut trees, possibly due to the importance of this soil property to Se retention in the soil.

The sunflower has adaptability to growing regions with different climatic and soil characteristics, showing drought tolerance and high-quality oil production. The State of Rio Grande do Sul is the third largest sunflower producer in Brazil, with research related to the sunflower breeding initiated after the decade of 1950. The aim of this study was to evaluate the genetic progress for grain yield, oil content, and oil yield of sunflower (Helianthus annuus L.) in the State of Rio Grande do Sul. Data of grain yield, oil content, and oil yield obtained from 58 sunflower cultivar yield trials in 19 municipalities in Rio Grande do Sul during the period from 2005 to 2014 were used. Genetic progress was studied according to the methodology proposed by Vencovsky and data from sunflower cultivar yield trials were used. Annual genetic progress of sunflower during the period of 10 years (2005-2014) was 132.46 kg⋅ha -1 ⋅year -1 for grain yield, -0.17%/year for oil content, and 48.11 kg⋅ha -1 ⋅year -1 for oil yield. The sunflower-breeding programs in the State of Rio Grande do Sul were efficient for the traits grain yield and oil yield and presented no efficiency for oil content.

Desta forma, este artigo apresenta uma compilação e discussão dos principais parâmetros ambientais e materiais que influenciam na penetração de cloretos em estruturas de concreto presentes neste ambiente. Além disso, como estudo de caso, ensaios de espectroscopia de fluorescência de Raios-X em amostras de concreto foram realizados em pontos de algumas estruturas presentes em diferentes zonas de agressividade marinha. As conclusões deste trabalho mostram que a degradação de uma estrutura pode ser evitada desde a etapa de projeto e que há um grande número de variáveis ambientais e materiais que afetam o processo. Esse trabalho contribui para a evolução do conhecimento sobre estruturas que sofrem degradação natural, expostas ao ambiente marinho. Os ensaios de espectroscopia de fluorescência de Raios-X mostraram que, sob uma perspectiva da corrosão, a zona de variação de maré é a mais agressiva às estruturas de concreto armado. Os ciclos de molhagem e secagem aos quais a zona de variação de maré está sujeita contribuem para acelerar a penetração dos cloretos no concreto. Portanto, de acordo com o tipo de zona marinha onde as estruturas podem estar presentes, o nível de agressividade quanto à corrosão induzida por cloretos é variável.

In recent decades, the rise violent phenomena in Brazil has reached epidemic proportions. However, the prevalence of domestic violence (DV) across different states in the country is not well established. The objective of this study was to describe the distribution of DV across Brazilian states from 2009 to 2014. An ecological study based on spatial analysis techniques was performed using Brazilian states as geographical units of analysis. A multilevel Poisson model was used to explain the risk of DV in Brazil according to age, sex, period (fixed effects), the Human Developing Index, and the victim's residence state (random effects). The overall average rate of DV almost tripled from 2009-2010 to 2013-2014. The rate of DV in Brazil in the 2013-2014 period was 3.52 times greater than the 2009-2010 period. The risk of DV in men was 74% lower than in women. The increase of DV against women during period under study occurred mainly in the Southeast, South, and Midwest. DV was more frequent in adolescence and adulthood. DV is gradually increasing in recent years in Brazil. More legislation and government programs are needed to combat the growth of violence in society.

Full Text Available INTRODUCTION: Shigella spp. are Gram-negative, nonsporulating, rod-shaped bacteria that belong to the family Enterobacteriaceae and are responsible for shigellosis or bacillary dysentery, an important cause of worldwide morbidity and mortality. METHODS: We studied the antibiotic resistance profiles of 122 Shigella spp. strains (81 S. flexneri, 41 S. sonnei, 1 S. boydii isolated from patients (female and male from 0 to 80 years of age presenting diarrhea in different districts of the State of Pará, in the North of Brazil. The antibiotic resistance of the strains, isolated from human fecal samples, was determined by the diffusion disk method and by using the VITEK-2 system. RESULTS: The highest resistance rate found was the resistance rate to tetracycline (93.8%, followed by the resistance rate to chloramphenicol (63.9% and to trimethoprim/sulfamethoxazole (63.1%. Resistance to at least three drugs was more common among S. flexneri than S. sonnei (39.5% vs. 10%. Six (4.9% strains were susceptible to all the antibiotics tested. All strains were susceptible to cefotaxime, ceftazidime, ciprofloxacin, nalidixic acid and nitrofurantoin. CONCLUSIONS: High rates of multidrug resistance in Shigella spp. are a serious public health concern in Brazil. It is extremely important to continuously monitor the antimicrobial resistances of Shigella spp. for effective therapy and control measures against shigellosis.

Full Text Available Objective. To determine the prevalence of anemia in children 6-59 months old in Pernambuco, a state in northeastern Brazil, so as to help guide health and nutrition policies there. Methods. In 1997 a representative sample of 777 young children had their hemoglobin concentration measured. The sampling process was in three stages. First, 18 municipalities were randomly selected to represent the state and its three geographic areas (metropolitan region of Recife, urban interior, and rural interior. Next, using census lists, 45 census sectors were randomly chosen. Finally, 777 children aged 6-59 months old were selected. Blood was collected by venipuncture, and hemoglobin was measured with a portable hemoglobinometer. In the analysis, prevalence was weighted to reflect the census age distribution. Results. The prevalence of anemia among children 6-59 months old was 40.9% for the state as a whole. Prevalence in the metropolitan region of Recife was 39.6%, and it was 35.9% in the urban interior. The rural interior had the highest prevalence, 51.4%. Prevalence was twice as high in children aged 6-23 months as among those 24-59 months old, 61.8% vs. 31.0% (chi² = 77.9, P < 0.001. The mean hemoglobin concentrations in the younger and older age groups were 10.4 g/dL (standard deviation (SD = 1.5 and 11.4 g/dL (SD = 1.4, respectively. There was no statistically significant difference between the sexes in terms of prevalence. Conclusions. This is the first statewide assessment of anemia prevalence among young children in Brazil. Given the very high prevalence of anemia among the children studied in Pernambuco, especially those in the age group of 6-23 months, public health interventions are needed.

Fatores institucionais e assimetria informacional: influência na estrutura de capital de empresas brasileiras.

Full Text Available O objetivo principal deste trabalho é analisar se a presença de importantes fatores institucionais brasileiros, como o acesso a fontes e linhas diferenciadas de financiamento, afeta a significância estatística e econômica da assimetria informacional, principal pressuposto da teoria de pecking order, na determinação da estrutura de capital de empresas brasileiras. Para tanto, foram utilizadas variáveis de controle, variáveis representativas de fatores institucionais e de assimetria informacional num painel de dados referente a empresas brasileiras de setores industriais, cujas ações foram negociadas na Bovespa, no período 1997-2007. Como principais resultados encontra-se que as variáveis tamanho, tangibilidade, rentabilidade e risco são importantes determinantes da estrutura de capital das empresas analisadas, sendo também significativa a participação de linhas diferenciadas no endividamento dessas empresas. Em resposta ao objetivo da pesquisa, verifica-se que a assimetria informacional não perde significância estatística e econômica no modelo proposto, após a inclusão de variáveis representativas de fatores institucionais, o que evidencia a importância da assimetria informacional na determinação da estrutura de capital de empresas brasileiras. O sinal negativo encontrado apoia a teoria de pecking order, na qual essas empresas seriam menos endividadas devido à possibilidade de captarem recursos por meio da emissão de ações. Ressalta-se que as proxies utilizadas para representar o atributo assimetria informacional constituem uma limitação da pesquisa. Em razão disso, sugere-se, para trabalhos futuros, a utilização de outras variáveis, com o propósito de verificar a consistência dos resultados aqui encontrados, bem como a análise da influência da assimetria informacional sobre o custo de capital de empresas brasileiras, com o intuito de verificar se empresas consideradas com menor assimetria informacional

Full Text Available Neste artigo, originalmente uma aula para concurso de professor titular junto ao Instituto de Psicologia da USP, são examinadas as noções de personalidade e de estrutura em sua aplicação ao diagnóstico de neurose, em psicopatologia de extração psicanalítica. Examina-se a consistência das relações de ordem, classe e gênero, que, por hipótese, ao lado da concepção de causalidade, subsidiam a força e pertinência de uma categoria diagnóstica. Discute-se o valor da exceção e a potência normativa de conformação da experiência clínica à racionalidade diagnóstica. Os resultados deste exame epistemológico preliminar nos levam a propor a tese crítica de que há menos homogeneidade no emprego da noção freudiana de neurose do que a recepção corrente vem admitindo. Argumenta-se que cada modelo metapsicológico, no qual emergem redefinições de neurose, corresponde a uma valência narrativa e uma forma de sofrimento distinto, sendo a exclusão da narrativa de sofrimento uma dimensão relevante para reconsiderar a noção de personalidade e de estrutura na diagnóstica psicanalítica.

Full Text Available The objective of this work was to evaluate the genetic diversity among Sclerotinia sclerotiorum isolates from Brazil and the USA, assess their aggressiveness variability, and verify the existence of an isolate-cultivar interaction. Isolate variability was determined by mycelial compatibility grouping (MCG, and isolate aggressiveness by cut-stem inoculations of soybean cultivars. Two experiments for MCGs and two for aggressiveness were conducted with two sets of isolates. The first set included nine isolates from the same soybean field in Brazil and nine from the Midwest region of the USA. The second set included 16 isolates from several regions of Brazil and one from the USA. In the first set, 18 isolates formed 12 different MCGs. In the second set, 81% of the isolates from Brazil grouped into a single MCG. No common MCGs were observed among isolates from Brazil and the USA. The isolates showed aggressiveness differences in the first set, but not in the second. Although aggressiveness differed in the first set, soybean cultivars and isolates did not interact significantly. Cultivar rank remained the same, regardless of the genetic diversity, aggressiveness difference, and region or country of origin of the isolate. Results from screening of soybean cultivars, performed by the cut-stem method in the USA, can be used as reference for researchers in Brazil.

Constructing public oral health policies in Brazil: issues for reflection.

Science.gov (United States)

Soares, Catharina Leite Matos

2012-01-01

This paper addresses the construction of public oral health policies in Brazil by reviewing the available literature. It includes a discussion of the social responses given by the Brazilian State to oral health policies and the relationship of these responses with the ideological oral health movements that have developed globally, and that have specifically influenced oral health policies in Brazil. The influence of these movements has affected a series of hegemonic practices originating from both Market Dentistry and Preventive and Social Dentistry in Brazil. Among the state activities that have been set into motion, the following stand out: the drafting of a law to regulate the fluoridation of the public water supply, and the fluoridation of commercial toothpaste in Brazil; epidemiological surveys to analyze the status of the Brazilian population's oral health; the inclusion of oral health in the Family Health Strategy (Estratégia de Saúde da Família - ESF); the drawing up of the National Oral Health Policy, Smiling Brazil (Brasil Sorridente). From the literature consulted, the progressive expansion of state intervention in oral health policies is observed. However, there remains a preponderance of hegemonic "dental" practices reproduced in the Unified Public Health Service (Sistema Único de Saúde - SUS) and the Family Health Strategy.

L. A. N. N. Agra

Full Text Available Abstract Mangrove swamps and forests cover over 137,000 km2 distributed latitudinally among subtropical zones, 7% of which are in Brazil, with a greater density in the country’s northernmost region. Considering that the community of Myxomycetes recorded for this environment is hardly known, three areas located in the state of Maranhão were investigated. Two field trips were conducted, one at the beginning of the rainy season and another during the dry season. In each area, two plots (125 m2 equidistant 100 m apart from each other were surveyed. In these areas, standing dead tree trunks and dead branches still attached to the mother plant that were above the tideline, were examined. On these same occasions, samples of the aerial litter and from the cortex of living trees (Rhizophora were collected for the preparation of moist chambers cultures. Twenty-one specimens were obtained from field and moist chambers, belonging to 11 species, distributed in nine genera and five families. Seven species are new records from Maranhão. There was a predominance of r-strategist (73% over K-strategist (27% species. Cribraria violacea, Comatricha tenerrima, Echinostelium minutum, and Fuligo septica are new worldwide records from mangrove environments, and Oligonema flavidum is reported for the first time from Brazil.

The following data were analyzed: accident period; patient's age and gender; bite site; envenomation severity; and time elapsed between the bite and medical treatment. We evaluated 211 cases recorded between January 2002 and December 2005, which resulted in an incidence coefficient of 32.4/100,000 inhabitants. Most accidents were due to the bite of snakes from the Bothrops genus (78.2%. The months between January and April had a larger number of accidents (93%-44.1%, although no significant differences were observed. Only one death occurred, resulting in a mortality rate of 0.5%. The lower limbs were the most frequently affected (66.3%. The majority of the victims were male (75.1%. The age group of most of the patients was from 21 to 30 years (20.8%. The accidents were classified as mild, moderate and severe, representing 44.9%, 47.6% and 7.5% of the cases, respectively. The time elapsed between the accident and medical treatment was less than 3h in most of the cases (80.7%, reflecting the high frequency of mild and moderate accidents (92.5% as well as the large number of healed patients.

Full Text Available Abstract The evaluation of ecosystem services is a tool to raise awareness about benefits of ecosystem functions for human well-being. In Brazil, few studies and reports assess ecosystem services in a watershed context. The aim of this paper is to fill this gap by assessing ecosystem services of Jacaré-Guaçu and Jacaré-Pepira Watersheds (São Paulo State, Brazil in a temporal scale of 10 years. Land cover and uses’ capacity to provide ecosystem services and drivers were assessed as a result of mapping these areas. Economic values were estimated based on literature information. Results showed that cultivated and managed terrestrial areas stands out over other areas and then, regulation and maintenance services are reduced in these areas. Wetlands and natural vegetation, with smaller areas, are important for the supply of regulation and maintenance services of both watersheds and economic values indicate the magnitude of degradation or maintenance/restoration.

Full Text Available To study mortality from liver cirrhosis in Espírito Santo State, Brazil, we reviewed death certificates (DC from 2000-2010 and medical records of deceased patients with investigation of alcoholism and hepatitis B or C. From a total of 218,410 DC, 3,554 deaths from liver cirrhosis were retrieved. The annual mortality rate was 19.8/100,000 for men and 4.31/100,000 for women, without significant changes after correction for ICD-R98 and R99 and without a significant increase in the annual percentage change. In 49% of death certificates, the aetiology of cirrhosis was defined: of these alcoholism in 81.5% of cases and viral hepatitis in 15.7%. Aetiology was confirmed in 262 reviewed records, including alcoholism (40.5%; hepatitis B or C (26.7%; other (3.8%; and cryptogenic (10.6%. The mean annual potential years of life lost were 5,946 years and 1,739 years for men and women respectively. The mortality rate from cirrhosis in Espírito Santo State is intermediate in relationship to worldwide data; alcoholism and hepatitis B or C were the main aetiologies; probably alcoholism is overestimated and hepatitis B and C viruses are underestimated as causes of cirrhosis registered on death certificates.

Privatization of Brazil's petroleum sector on track despite scandal

1992-01-01

This paper reports that the push to privatize Brazil's petroleum sector remains on track despite the taint of scandal that hit state oil company Petroleos Brasileiro SA and the ensuing political crisis for the administration of President Fernando Collor de Mello. Collor's efforts to reform Brazil's beleaguered economy have focused heavily on privatizing state-owned companies by selling assets or ending monopolies. Nowhere is that task more daunting than with Petrobras, one of the world's biggest petroleum companies, which has an entrenched monopoly over most upstream and downstream operations in the country. Collor and the energy ministers and chiefs of Petrobras during his administration have pressed measured to inject free market principles in Brazil's petroleum sector. The Collor administration earlier this year sent a bill to Brazil's Congress calling for a constitutional amendment to end Petrobras monopoly over exploration, production, transportation, refining, and exports and imports of oil and gas. The amendment is expected to be voted upon in 1993

Full Text Available Childhood malnutrition has been a major, long-standing health concern in northeastern Brazil. In response, during 1992_1994, the state government of Ceará, with financial support from the World Bank, established 34 new nutrition centers. During 1996 an evaluation of the centers was conducted to determine their effectiveness in treating children with malnutrition and to identify weaknesses in the system and possible solutions. Also evaluated were the adequacy of resources, admission and discharge criteria, staff training, and community satisfaction. Effectiveness was found to be low. Treatment procedures did not conform with World Health Organization recommendations. Rates of weight gain were inadequate, and the mean duration of rehabilitation-8.7 months-was too long. Case fatality in two centers was unacceptably high, 40% and more. Entry and exit criteria for rehabilitation were ill defined, resulting in some nonmalnourished children being enrolled. Few staff were adequately trained; knowledge was weak, especially about case management; and mothers were not effectively instructed. Recommendations include setting objectives for the centers, improving referral systems, standardizing entry criteria, improving case management, and establishing performance indicators.

This paper discusses schistosomiasis transmission in São José da Serra, a village with a population of 500 in the county of Jaboticatubas, Minas Gerais State, Brazil. The area receives thousands of visitors a year for ecotourism. The study was motivated by a case of acute schistosomiasis involving a couple that spent the 2007 Carnival (Mardi Gras) holiday in the area. Stool tests from 268 local residents (53.6% of the population) showed that 35 (13%) were positive for the infection. A comparison with a previous survey (2005) in the same location showed an increase in the schistosomiasis-positive rate from 9.6% to 12.5%, among the 56 individuals who participated in both surveys. A malacological survey of 65 Biomphalaria glabrata snails showed one specimen (1.5%) eliminating cercariae. In a similar survey in 2005, no positive snail specimens were found. The study indicates that active schistosomiasis transmission is occurring in the area, and that integrated educational programs are needed for both the local community and tourists.

A pesquisa caracteriza-se por um estudo de natureza formal, causal, ex post facto, desenvolvido em ambiente de campo, rotulada como uma investigação transversal estatística. A amostragem demandou a exclusão de 52 companhias, tendo restado 448 empresas. A operacionalização dos constructos da pesquisa à solução da problematização desenvolveu-se por meio de estatísticas descritivas, testes de hipóteses não paramétricos (Kolmogorov-Smirnov, Mann-Whitney e Kruskal-Wallis e regressão linear simples, calculados com o software SPSS. Os resultados sugerem a existência de relação negativa entre endividamento e rentabilidade, conduzindo à aceitação da Teoria de Pecking Order, rejeitando-se a existência de uma estrutura de capital ótima (Trade-Off ou ainda a Teoria da Irrelevância da Estrutura de Capitais. Analogamente, os resultados da análise isolada para as empresas rentáveis estão apoiados pela Teoria de Pecking Order. Todavia, para o grupo de empresas não rentáveis, verifica-se a sobreposição das Teorias de Trade-Off e da Irrelevância da Estrutura de Capitais à Teoria de Pecking Order. Os resultados provenientes da análise dos quatro setores mais representativos mostram-se semelhantes àqueles verificados na análise conjunta das 448 empresas estudadas, todavia, fornecem indícios de variáveis que podem proporcionar conclusões adicionais à temática pesquisada. No entanto, em linhas gerais, depreende-se que a Teoria da hierarquia de Pecking Order tende a ser mais consistente para explicar a estrutura de capital das maiores empresas sul brasileiras.

Highlights: ► We constructed future scenarios of emissions of greenhouse gases in waste. ► Was used the IPCC methodology for calculating emission inventories. ► We calculated the costs of abatement for emissions reduction in landfill waste. ► The results were compared to Brazil, state and city of Rio de Janeiro. ► The higher the environmental passive, the greater the possibility of use of biogas. - Abstract: This paper examines potential changes in solid waste policies for the reduction in GHG for the country of Brazil and one of its major states and cities, Rio de Janeiro, from 2005 to 2030. To examine these policy options, trends in solid waste quantities and associated GHG emissions are derived. Three alternative policy scenarios are evaluated in terms of effectiveness, technology, and economics and conclusions posited regarding optimal strategies for Brazil to implement. These scenarios are been building on the guidelines for national inventories of GHG emissions (IPCC, 2006) and adapted to Brazilian states and municipalities’ boundaries. Based on the results, it is possible to say that the potential revenue from products of solid waste management is more than sufficient to transform the current scenario in this country into one of financial and environmental gains, where the negative impacts of climate change have created a huge opportunity to expand infrastructure for waste management

Full Text Available White grubs (Coleoptera, Melolonthidae in the "Planalto Region", Rio Grande do Sul state, Brazil: Key for identification, species richness and distribution. The objective of this study was to survey the occurrence and geographic distribution of white grub species (Coleoptera, Melolonthidae in cultivated and non-cultivated fields of the "Planalto Region", Rio Grande do Sul state, Brazil and develop a key at genus-level. Twenty-eight species from 15 genera and three subfamilies were recorded: Dynastinae, Melolonthinae and Rutelinae. The species or genera recorded for the first time in the state are: Cyclocephala metrica, C. tucumana, Isonychus albicinctus, Liogenys bidenticeps, L. fusca, L. obesa and L. sinuaticeps, Paranomala violacea, as well as unidentified species of Amononyx, Dicrania, Leucothyreus, Macrodactylus, Plectris and Rhizogeniates. Among the species recorded, 23 were associated with winter crops. Only Cyclocephala metrica, Dyscinetus rugifrons, two species of Leucothyreus and one species of the tribe Sericini were not present in cultivated crop fields. Cyclocephala flavipennis and Diloboderus abderus occurred in most of the municipalities sampled, often associated with Plectris sp., C. modesta and C. putrida. The highest richness of melolonthids was concentrated in the northeast of the Planalto region.

Yellow fever virus is a mosquito-borne flavivirus that causes yellow fever, an acute infectious disease that occurs in South America and sub-Saharan Africa. Most patients with yellow fever are asymptomatic, but among the 15% who develop severe illness, the case fatality rate is 20%-60%. Effective live-attenuated virus vaccines are available that protect against yellow fever (1). An outbreak of yellow fever began in Brazil in December 2016; since July 2017, cases in both humans and nonhuman primates have been reported from the states of São Paulo, Minas Gerais, and Rio de Janeiro, including cases occurring near large urban centers in these states (2). On January 16, 2018, the World Health Organization updated yellow fever vaccination recommendations for Brazil to include all persons traveling to or living in Espírito Santo, São Paulo, and Rio de Janeiro states, and certain cities in Bahia state, in addition to areas where vaccination had been recommended before the recent outbreak (3). Since January 2018, 10 travel-related cases of yellow fever, including four deaths, have been reported in international travelers returning from Brazil. None of the 10 travelers had received yellow fever vaccination.

Full Text Available O presente trabalho é uma pesquisa teórico-empírica que utiliza a análise de regressão linear múltipla com o objetivo de testar a validade de hipóteses relacionadas à influência da tributação do lucro na estrutura de capital das grandes empresas no Brasil. Segundo a teoria do tradeoff, a empresa, incentivada pela vantagem fiscal do endividamento, recorre a capitais de terceiros até o nível em que os custos associados aos riscos de falência superam essa vantagem. A teoria do pecking order, por sua vez, preconiza uma hierarquização das fontes de financiamento e não atribui à tributação do lucro papel relevante na explicação do endividamento. Duas hipóteses foram postas à prova: a primeira testou a validade da teoria do tradeoff quanto à existência de impacto da tributação do lucro no endividamento. A testou a presença dessa relação nas firmas com alto endividamento e baixo nível de tributação, para as quais não haveria a vantagem fiscal do endividamento. A pesquisa tomou por base valores médios dos dados de 2001 a 2003 das 500 maiores empresas estabelecidas no Brasil, segundo a Revista Exame. A hipótese central da pesquisa restou confirmada: existe uma relação positiva entre o nível de tributação do lucro e o grau de endividamento. Essa relação foi verificada, também, para as empresas com alto endividamento e baixo nível de tributação do lucro. Esses achados confirmaram o maior poder preditivo da teoria do tradeoff em detrimento da teoria do pecking order quanto ao impacto da tributação do lucro sobre a decisão de endividamento.This paper is an empirical research that uses analysis of multiple linear regression to test validity of hypotheses related to influence of profit taxation in capital structure of large companies in Brazil.

Full Text Available Consensual unions are a well-known practice among the lower social strata in Latin America. However, this type of union is increasing in the region, among higher educated groups and in countries where they were never widespread, such as in Brazil. This study uses couples' data from the demographic census available at IPUMS (N=193,689 to identify the socioeconomic and cultural features of consensual unions in Brazil. The effects of women's education, couples' income, children, and religion on nuptial behavior are analyzed. Utilizing logistic multilevel analysis, special attention is paid to the effect of differences in the cultural environment of states in the five major regions in which these unions occur. Results indicate that socioeconomic factors affect the incidence of consensual unions in Brazil. Consensual unions are more common among lower income couples and less educated women, but are also found among the upper classes. Cultural diversity between Brazilian states is also reflected in nuptial behavior. Significant variance at the state level is partially explained by the ethnic composition of each state.

The geographic distribution of cutaneous leishmaniasis (CL) makes it a disease of major clinical importance in Brazil, where it is endemic in the state of Paraná. The objective of this study was to analyze the spatial distribution of CL in Paraná between 2001 and 2015, based on data from the Sistema de Informação de Agravos de Notificação (Information System for Notifiable Diseases) regarding autochthonous CL cases. Spatial autocorrelation was performed using Moran's Global Index and the Local Indicator of Spatial Association (LISA). The construction of maps was based on categories of association (high-high, low-low, high-low, and low-high). A total of 4,557 autochthonous cases of CL were registered in the state of Paraná, with an annual average of 303.8 (± 135.2) and a detection coefficient of 2.91. No correlation was found between global indices and their respective significance in 2001 (I = -0.456, p = 0.676), but evidence of spatial autocorrelation was found in other years (pCinzas-Laranjinha, and Ribeira areas. The state of Paraná should keep a constant surveillance over CL due to the prominent presence of socioeconomic and environmental factors such as the favorable circumstances for the vectors present in peri-urban and agriculture áreas.

Institutional framework changes in Brazil's energy industries

International Nuclear Information System (INIS)

De Almeida, E.; Queiroz Pinto JR, H.

2009-01-01

The liberalization of the Brazilian energy sector in the 1990's was meant to drastically reduce the role of the State in the sector. This reform has not had the desired results. Private investment could not guarantee the expansion of the Brazilian energy sector at the necessary speed. The first half of this decade has been marked by problems of electricity supply and a rather timid role of private investment in boosting energy supply. During the second half of the decade, liberal reform of the energy sector in Brazil has gone through major adjustments, marked by the search for a new compromise between the role of the State and the private sector. This paper highlights the institutional evolution of Brazil's energy or industries and tries to show how risk for public and private investment has been reduced by the adoption of new institutional and economic mechanisms of coordination. In the current institutional framework, the State plays an important role in coordinating the investment process for the expansion of supply. The pace of investment in Brazil in the energy sector has accelerated significantly after the adoption of the new coordination mechanisms. (authors)

Sporotrichosis is a widespread subcutaneous mycosis caused by the dimorphic fungi now known as the Sporothrix schenckii complex. This complex is comprised of at least six species, including Sporothrix albicans, Sporothrix brasiliensis, Sporothrix globosa, Sporothrix luriei, Sporothrix mexicana and S. schenckii. Cases of sporotrichosis have significantly increased in Brazil over the past decade, especially in the state of Rio de Janeiro (RJ), where an epidemic among cat owners has been observed. The zoonotic transmission from cats to humans suggests a common source of infection and indicates that animals can act as vectors. We performed a molecular characterisation of samples collected during the first outbreak of familial sporotrichosis caused by S. brasiliensis in the state of Espírito Santo, Brazil. These results represent the first description of such an outbreak outside the endemic area of zoonotic sporotrichosis in RJ.

Full Text Available Geographic Information Systems (GISs are composed of useful tools to map and to model the spatial distribution of events that have geographic importance as schistosomiasis. This paper is a review of the use the indicator kriging, implemented on the Georeferenced Information Processing System (SPRING to make inferences about the prevalence of schistosomiasis and the presence of the species of Biomphalaria, intermediate hosts of Schistosoma mansoni, in areas without this information, in the Minas Gerais State, Brazil. The results were two maps. The first one was a map of Biomphalaria species, and the second was a new map of estimated prevalence of schistosomiasis. The obtained results showed that the indicator kriging can be used to better allocate resources for study and control of schistosomiasis in areas with transmission or the possibility of disease transmission.

Full Text Available AIM: This study gathers the main results obtained from studies regarding dynamic of aquatic macrophyte community in natural and managed wetlands of Southern Brazil. We analyzed the aquatic macrophytes diversity in wetlands of Southern Brazil, the environmental factors that determine the structure of the aquatic macrophyte community in fragmented wetlands, the effects of floods on the dynamics of macrophytes, and the contributions to the rice field for the conservation of aquatic macrophytes; METHODS: The information was obtained from several researches carried in several spatial scales and different wetlands types over the last 10 years in Southern Brazil; RESULTS: The studies have reported the occurrence of approximately 250 species of aquatic macrophytes. Wetland area, habitat diversity, altitude and hydroperiod were determinant for macrophyte richness and composition in wetlands of Southern Brazil. Furthermore, flood events, long or short-term ones, are strongly associated to the structure of the aquatic macrophyte community. The rice field systems of Southern Brazil (crops and irrigation channel shelter a representative number of species of macrophyte found at natural wetlands in this region. The agricultural practices adopted over rice cultivation cycle in the rice fields have influenced the macrophyte richness and biomass. The different hydrological management practices adopted after the harvesting period (presence or lack of water surface did not influence the macrophyte richness and biomass, however it influenced the species composition; CONCLUSIONS: The increasing process of wetland degradation (e.g. fragmentation, flood control and rice field expansion presents a threat to the conservation aquatic macrophyte species.OBJETIVO: Este estudo reúne os principais resultados obtidos em trabalhos sobre a dinâmica da comunidade de macrófitas aquáticas em áreas úmidas naturais e manejadas do sul do Brasil.

Little is known about the quality and quantity of cost-utility analyses (CUAs) in Brazil. The objective of this study was to provide a systematic review of published CUAs of healthcare technologies in Brazil. We performed a systematic review of economic evaluations studies published in MEDLINE, EMBASE, LILACS (Latin American and Caribbean Health Sciences Literature), SciELO (Scientific Electronic Library Online), NHS EED (National Health Service Economic Evaluation Database), HTA (Health Technology Assessment) Database, Web of Science, Scopus, Bireme (Biblioteca Regional de Medicina), BVS ECOS (Health Economics database of the Brazilian Virtual Library of Health), and SISREBRATS (Sistema de Informação da Rede Brasileira de Avaliação de Tecnologias em Saúde [Brazilian Network for the Evaluation of Health Technologies]) from 1980 to 2013. Articles were included if they were CUAs according to the classification devised by Drummond et al. Two independent reviewers screened articles for relevance and carried out data extraction. Disagreements were resolved through discussion or through consultation with a third reviewer. We performed a qualitative narrative synthesis. Of the 535 health economic evaluations (HEEs) relating to Brazil, only 40 were CUAs and therefore included in the analysis. Most studies adhered to methodological guidelines for quality of reporting and 77.5% used quality-adjusted life-years (QALYs) as the health outcome. Of these studies, 51.6% did not report the population used to elicit preferences for outcomes and 45.2% used a specific population such as expert opinion. The preference elicitation method was not reported in 58.1% of these studies. The majority (80.6%) of studies did not report the instrument used to derive health state valuations and no publication reported whether tariffs (or preference weights) were national or international. No study mentioned the methodology used to estimate QALYs. Many published Brazilian cost-utility studies

Full Text Available Nas transformações do catolicismo brasileiro, o foco regional se relaciona com a análise da escala local e global como dimensões extremamente articuladas. Esta articulação caracteriza a Igreja local de Curitiba (PR com uma territorialidade de duas instâncias, influenciadas por tensões escalares de caráter global próprias da hierarquia universal da Igreja e tensões regionais específicas da Igreja local. Afora estas forças de caráter endógeno da estrutura eclesiástica, verificam-se também tensões exógenas à própria Igreja, representadas por instituições não-católicas e mesmo instituições seculares. O último quarto do século XX demonstrou uma crise da representação dominante da Igreja Católica Romana no Brasil. A conjuntura secular das cidades e a retração no espírito missionário da Igreja motivaram o diagnóstico de uma certa estagnação do domínio simbólico da Igreja. Com efeito, o pluralismo religioso dos grandes centros urbanos cunhou uma nova realidade, baseada em um crescente questionamento do mito do Brasil católico. O crescimento de movimentos religiosos pentecostais e neopentecostais representou nas décadas de 1980 e 1990 um impacto considerável na forma de a religiosidade popular fazer uma segunda identidade religiosa.

This study aimed to evaluate indigenous peoples' access to medium and high-complexity health services in the municipality of Cuiabá, Mato Grosso State, Brazil, through the Casa de Saúde Indígena or Indigenous Peoples' Clinic (CASAI Cuiabá). A single case study with a qualitative approach was conducted at CASAI Cuiabá. Data were obtained from observation of the work routines at CASAI Cuiabá, semi-structured interviews with health professionals and administrators from the Cuiabá Special Indigenous Health District (DSEI) and CASAI Cuiabá, and document analysis. Data analysis used a matrix derived from the theoretical and logical model of accessibility, validated by the Delphi method with a group of experts on indigenous peoples' health. Despite advances achieved by CASAI in improving indigenous peoples' access, there are persistent social, organizational, cultural, and geographic barriers in access to medium and high-complexity health services in Cuiabá. The study highlights the need for specific strategies to improve access to health services by indigenous peoples in Mato Grosso State.

Full Text Available Inaugurada em 2006, a Usina Hidrelétrica de Irapé possui a mais alta barragem do país, com 210 m, que vem sendo monitorada pelo Observatório Sismológico da Universidade de Brasília desde o começo do enchimento de seu reservatório. Apresentando sismicidade causada pelo aumento da tensão crustal logo após o início do represamento, a Sismicidade Desencadeada por Reservatório da Usina Hidrelétrica de Irapé permanece como um importante objeto de estudo para o entendimento deste fenômeno. O presente trabalho se propôs a estudar a sismicidade registrada de janeiro a maio de 2006, assim como a caracterizar a geologia ao redor da Usina Hidrelétrica de Irapé com o intuito de identificar e descrever as estruturas que permitam melhor compreender os eventos sísmicos. A orientação espacial dos eventos sísmicos obtidos pela análise das polaridades e da forma de onda condiz com aquelas dos lineamentos de relevo. As estruturas encontradas podem ser associadas a uma maior, de direção principal NE/SW, com dezenas de quilômetros, que seria responsável pela captura dos rios Jequitinhonha e Araçuaí, interpretada neste trabalho como uma estrutura relacionada a uma fase tardia do Evento Brasiliano. O diagrama de solução do mecanismo focal gerado utilizando um método de inversão da forma de onda no domínio do tempo indica que a direção dos possíveis planos de falhas está correlacionada ao principal direcionamento das estruturas rúpteis na área de trabalho.

The present study aimed to assess mortality rates and related demographic factors among indigenous peoples in the State of Mato Grosso do Sul, Central-West Brazil, compared to the State's general population. Mortality rates were estimated based on data obtained from the Health Care Database for Indigenous Peoples and monthly patient care records as well as demographic data from the Brazilian Unified National Health System (SUS) and mortality data from the SUS Mortality Database. Compared to the overall population, among indigenous peoples there were proportionally more individuals under 15 years of age and fewer elderly, besides higher mortality rates at early ages and from infectious and parasitic diseases. Indigenous men showed significantly higher mortality rates from external causes and respiratory and infectious diseases, while among women the mortality rates from external causes and infectious diseases were higher. Suicide rates among young indigenous individuals were also particularly alarming. Indigenous people's health conditions are worse than those of the general population in Mato Grosso do Sul.

1985-01-01

Magnetic, radiometric and gamma spectrometric surveys have been carried out on the Janjao diatreme which outcrops near Lajes in central-east Santa Catarina State, Brazil. The body is deeply weathered on the surface and its concentrates contain serpentinized olivine, phlogopote, pyroxenes, ilmenites, garnet and zircon. The interpretation of the magnetic anomaly revealed an irregular diatreme whose main dimensions are 50 X 190 meters. A vertical to subvertical dyke cuts the main diatreme. The radiometric anomaly as well as the potassium content helped to delineate the contacts between the diatreme and its country rocks (sandstones). Faults striking NNE controlled the emplacement of the Janjao diatreme as well as the intrusion of an alkaline dyke located near the diatreme. (Author) [pt

Ureaplasma diversum infection in bovine females may result in various reproductive problems, including granular vulvovaginitis, abortion, weak calves, salpingitis, and spontaneous abortion. The presence of U. diversum in a dairy bovine population from midwestern Brazil has not been established. The aim of this study was to determine whether U. diversum was present in dairy cattle from midwestern Brazil using polymerase chain reaction (PCR). Vulvovaginal mucus was analyzed from 203 cows located in six municipalities in the north region of Mato Grosso State, Brazil. A total of 25% of dairy cows with vulvovaginitis were positive for U. diversum. The factors evaluated were included in a multivariable logistic regression model with the presence of at least one positive cow in the herd serving as the dependent variable. Three variables were significantly associated with a U. diversum-positive PCR and were included in the final multivariable model: number of parities, vulvar lesions, and reproductive problems. For each new parity, the chance of U. diversum infection decreased 0.03-fold, indicating that cows with the highest number of parities were more protected. The presence of vulvar lesions was increased 17.6-fold in females positive for U. diversum, suggesting that this bacterium could be related to the red granular lesions in the vulvar mucosa, whereas reproductive problems were increased 7.6-fold. However, further investigations should be conducted to ascertain the effects of U. diversum in association with other mycoplasma species in the herds studied.

Assessment of the trophic state of a hypersaline-carbonatic environment: Vermelha Lagoon (Brazil.

Full Text Available Vermelha Lagoon is a hypersaline shallow transitional ecosystem in the state of Rio de Janeiro (Brazil. This lagoon is located in the protected area of Massambaba, between the cities of Araruama and Saquarema (Brazil, and displays two quite uncommon particularities: it exhibits carbonate sedimentation and displays the development of Holocene stromatolites. Due to both particularities, the salt industry and property speculation have been, increasingly, generating anthropic pressures on this ecosystem. This study aims to apply a multiproxy approach to evaluate the trophic state of Vermelha Lagoon based on physicochemical parameters and geochemical data for the quantification and qualification of organic matter (OM, namely total organic carbon (TOC, total sulfur (TS, total phosphorus (TP and biopolymeric carbon (BPC, including carbohydrates (CHO, lipids (LIP and proteins (PTN. The CHO/TOC ratio values suggest that OM supplied to the sediment is of autochthonous origin and results, essentially, from microbial activity. The cluster analyses allowed the identification of four regions in Vermelha Lagoon. The Region I included stations located in shallow areas of the eastern sector of Vermelha lagoon affected by the impact of the artificial channel of connection with Araruama Lagoon. The Region II, under the influence of salt pans, is characterized by the highest values of BPC, namely CHO promoted by microbiological activity. The Region III include stations spread through the lagoon with high values of dissolved oxygen and lower values of TP. Stromatolites and microbial mattes growth was observed in some stations of this sector. Region IV, where the highest values of TOC and TS were found, represents depocenters of organic matter, located in general in depressed areas. Results of this work evidences that the Vermelha Lagoon is an eutrophic but alkaline and well oxygenated environment (at both water column and surface sediment where the autotrophic

Brazil to Join the European Southern Observatory

2010-12-01

The Federative Republic of Brazil has yesterday signed the formal accession agreement paving the way for it to become a Member State of the European Southern Observatory (ESO). Following government ratification Brazil will become the fifteenth Member State and the first from outside Europe. On 29 December 2010, at a ceremony in Brasilia, the Brazilian Minister of Science and Technology, Sergio Machado Rezende and the ESO Director General, Tim de Zeeuw signed the formal accession agreement aiming to make Brazil a Member State of the European Southern Observatory. Brazil will become the fifteen Member State and the first from outside Europe. Since the agreement means accession to an international convention, the agreement must now be submitted to the Brazilian Parliament for ratification [1]. The signing of the agreement followed the unanimous approval by the ESO Council during an extraordinary meeting on 21 December 2010. "Joining ESO will give new impetus to the development of science, technology and innovation in Brazil as part of the considerable efforts our government is making to keep the country advancing in these strategic areas," says Rezende. The European Southern Observatory has a long history of successful involvement with South America, ever since Chile was selected as the best site for its observatories in 1963. Until now, however, no non-European country has joined ESO as a Member State. "The membership of Brazil will give the vibrant Brazilian astronomical community full access to the most productive observatory in the world and open up opportunities for Brazilian high-tech industry to contribute to the European Extremely Large Telescope project. It will also bring new resources and skills to the organisation at the right time for them to make a major contribution to this exciting project," adds ESO Director General, Tim de Zeeuw. The European Extremely Large Telescope (E-ELT) telescope design phase was recently completed and a major review was

AIDS is the fourth leading cause of death worldwide and, currently, the overall prevalence rate of HIV infection in Brazil is 0.5% among men and 0.3% among women. To evaluate the spatiotemporal trend of AIDS in Brazil from 2006 to 2012 and its relationship with human development index (HDI) and their components income, education and life expectancy. This ecological study evaluate the spatiotemporal trend of standardized incidence ratio of AIDS among adults in Brazil from 2006 to 2012 and its relationship with HDI by using a Bayesian analysis, considering the Brazilian Federal Units as units of analysis. The proposed statistical model allows obtaining a standardized incidence ratio (SIR, adjusted by gender and age). Among the men, our results show higher incidence rates in the States of the Southern regions as well as in the state of Amazonas (Northern Brazil). In females, we found other patterns for SIR, with higher incidence rates in the states of Rio de Janeiro (Southeast region), Rio Grande do Sul and Santa Catarina (both in Southern region). Among men it was observed as an expressive association between the SIR values and the overall HDI and income and education components, but it was observed to have an inverse association with the life expectancy component. Among women, it is noted that the SIR values are associated with the overall HDI and the education components only at the beginning of the studied period. AIDS remains a major public health problem in Brazil, mainly in the southern and southeastern regions of the country. Considering its association with HDI, it is noted that the disease still remains related to the pattern observed in the early years of the studied period, at least in the more developed regions of Brazil. This certainly happened because of the chronicity of the disease, thus affecting people with good socioeconomic status.

Following reports of two autochthonous cases of sylvatic yellow fever in the State of São Paulo, Brazil, in 2000, entomological surveys were conducted with the objective of verifying the occurrence of vector species in forest environments close to or associated with riparian areas located in the western and northwestern regions of the State. Culicidae were captured in 39 sites distributed in four regions. Haemagogus leucocelaenus and Aedes albopictus were the most abundant species and were captured in all the regions studied. H. leucocelaenus was the most abundant species in the municipalities of Santa Albertina and Ouroeste, where the two cases of sylvatic yellow fever had been reported. Mosquitoes from the janthinomys/capricornii group were only found at eight sites in the São José do Rio Preto region, while Sabethes chloropterus was found at one site in Ribeirão Preto. H. leucocelaenus showed its capacity to adapt to a secondary and degraded environment. Our results indicate a wide receptive area for yellow fever transmission in the State of São Paulo, with particular emphasis on the possibility of H. leucocelaenus being involved in the maintenance of this sylvatic focus of the disease.

Full Text Available Inventories on necrophagous insects carried out in Brazil encompass mostly species from the southeastern and central-western regions of the country. This review aims to produce the first checklist of necrophagous Diptera and Coleoptera species of forensic relevance in northeastern Brazil, an area that concentrates high rates of homicides. We performed a literature survey on scientific articles, theses and dissertations regarding necrophagous insect species in the region, and contacted scientists who develop research on forensic entomology. Fifty-two species of Diptera belonging to eight families with previous record of necrophagy were reported in the region: Sarcophagidae, Calliphoridae, Muscidae, Fanniidae, Piophilidae, Phoridae, Anthomyiidae and Stratiomyidae. Coleopteran species from six families of forensic relevance were registered, although taxonomical identification remained superficial. Bait traps were the most frequent methodology used, followed by collection on animal carcasses. Seven Dipteran species from two families were registered on human cadavers. All species had been previously reported in other Brazilian states and/or other countries, although none has been effectively used in legal procedures in the region. The status of research on forensic entomology in northeastern Brazil is incipient, and the checklist produced here contributes to the knowledge on the local diversity of necrophagous insects.

A climate system is characterized to be a complex non-linear system. In order to describe the complex characteristics of precipitation series in Paraíba State, Brazil, we aim the use of sample entropy, a kind of entropy-based algorithm, to evaluate the complexity of precipitation series. Sixty-nine meteorological stations are distributed over four macroregions: Zona da Mata, Agreste, Borborema, and Sertão. The results of the analysis show that intricacies of monthly average precipitation have differences in the macroregions. Sample entropy is able to reflect the dynamic change of precipitation series providing a new way to investigate complexity of hydrological series. The complexity exhibits areal variation of local water resource systems which can influence the basis for utilizing and developing resources in dry areas.

Full Text Available Ticks were obtained from dogs from February to September of 1999 at weekly intervals, in the County of Piraí, State of Rio de Janeiro. Four hundred seventy four ixodids were taxonomically identified, 103 Amblyomma cajennense, seven Amblyomma ovale, 209 Rhipicephalus sanguineus, and 155 Amblyomma sp. An hemolymph test associated with Giemsa's stain revealed two specimens in 163 ticks tested (R. sanguineus and Amblyomma sp, containing rickettsia-like organisms. Direct immunofluorescence verified the presence of spotted fever group rickettsia in one specimen of R. sanguineus. Considering the limited information on rickettsiosis in Brazil, principally in relation to the vectors involved in perpetuating it in foci, these preliminary results give us an idea on the importance of infection in ticks, allowing to expand our knowledge on this zoonosis.

Alcohol and drug use by truck drivers is a current problem in Brazil. Though there is evidence that alcohol consumption is occurring in higher proportions, the use of stimulant drugs to avoid fatigue and to maintain the work schedule has also been reported. The purpose of this study was to estimate the incidence of alcohol and illicit drug use among truck drivers on São Paulo state roads. São Paulo is the most populous state in Brazil and has the largest industrial park and economic production in the country. Data were assessed not only using a questionnaire but also, and more reliably, through toxicological analysis of oral fluid samples. Between the years 2002 and 2008, 1250 oral fluid samples were collected from truck drivers on the roads during morning hours. The samples were tested for the presence of alcohol, cocaine, tetrahydrocannabinol (THC), and amphetamine/methamphetamine. A previously published, validated gas chromatographic (gas chromatography-flame ionization detection and gas chromatography-mass spectrometry) method was applied to the samples for alcohol and drug detection. Of the total analyzed samples, 3.1 percent (n = 39) were positive: 1.44 percent (n = 18) were positive for alcohol, 0.64 percent (n = 8) for amphetamines, 0.56 percent (n = 7) for cocaine, and 0.40 percent (n = 5) for THC. In one case, cocaine and THC were detected. The results are indicative of the extent of alcohol and drug use by truck drivers in the state of São Paulo, Brazil. This research provides evidence that not only alcohol but also illicit drug use is a real problem among professional drivers. The use of these substances should be controlled to better promote safe driving conditions on Brazilian roads.

Full Text Available Abstract Trypanosomiasis caused by Trypanosoma vivax has increased the reports in Brazil in the last decade. An outbreak is herein first reported in the state of Goiás, from May 2016 to January 2017. The outbreak start occurred in the city of Ipameri (Goiás after the introduction of 18 auctioned cows from the state of Minas Gerais. Direct parasitological test (blood smears and polymerase chain reactions targeting the catL genes diagnosed T. vivax infection. Fifty six cows from a herd of 161 were infected; 12 died during the outbreak and 44 animals persistently positive (by blood smears even after chemical treatment were discarded. After this first case, five other cases were detected in state of Goiás. The spread of this disease can be linked to the commercialization of animals carrying T. vivax, allied to the iatrogenic transmission practice, using a single needle and syringe for all cows, during oxytocin administration before each milking.

Brazil and the State of Rio Grande do Sul are experiencing a period of rapid industrial development. Global investment has been forecast to reach $240 billion over the next five to seven years. This level of development is likely to result in a sharp increase in the consumption of plastic products made from olefins and from aromatic products. Accordingly, Copesul, the centre of raw materials for the State complex, is expected to increase its production of ethane from 685 tonnes to 1.13 million tonnes after 1999. The government has established a program of incentives to stimulate investment in third generation industries. Also, the State petrochemical industry has been rendered more competitive as a result of the purchase of the latest generation equipment. The principal challenges that exist for the petrochemical industry in Brazil and for that matter, around the world, are to reduce production costs and to preserve the natural environment. Another challenge, also world-wide, is to address the issue of plastic residues and to eliminate such residues through plastic recycling programs

2018-06-01

Full Text Available ABSTRACT Galls are specific changes induced by insects on plant organs mainly through increases in plant cell number and/or size. Gall diversity is easy to recognize in the field because gallers are mostly species-specific, and thus each gall morphotype can be a proxy for a galling species. Insect galls are virtually unknown in Seasonal Deciduous and Semi-Deciduous forests of southern Brazil. Here, galls and host plants were surveyed between 2015 and 2017 in four forest fragments of Rio Grande do Sul State in these two vegetation types, in secondary-growth and areas under restoration. We recorded 89 gall morphotypes, with gallers belonging to Lepidoptera and Diptera, with the latter represented mainly by Cecidomyiidae. Galls were associated to 46 plant species in 27 families. Asteraceae, Piperaceae, Fabaceae, Myrtaceae and Lauraceae were the richest families in terms of galls, whilst Piper aduncum and Mikania glomerata were superhosts. Most galls occurred in leaves and shoots. The most common shapes were fusiform, globoid and lenticular. Forty-eight gall morphotype records are new for both Rio Grande do Sul and Brazil, an expressive number considering only two seasonal forest types sampled and few sampling points, showing how important surveys still are for these little know fauna both in taxonomic and ecological terms.

Full Text Available After detecting the death of Howlers monkeys (genus Alouatta and isolation of yellow fever virus (YFV in Buri county, São Paulo, Brazil, an entomological research study in the field was started. A YFV strain was isolated from newborn Swiss mice and cultured cells of Aedes albopictus - C6/36, from a pool of six Haemagogus (Conopostegus leucocelaenus (Hg. leucocelaenus mosquitoes (Dyar & Shannon collected at the study site. Virus RNA fragment was amplified by RT-PCR and sequenced. The MCC Tree generated showed that the isolated strain is related to the South American I genotype, in a monophyletic clade containing isolates from recent 2008-2010 epidemics and epizootics in Brazil. Statistical analysis commonly used were calculated to characterize the sample in relation to diversity and dominance and indicated a pattern of dominance of one or a few species. Hg. leucocelaenus was found infected in Rio Grande do Sul State as well. In São Paulo State, this is the first detection of YFV in Hg. leucocelaenus.

Full Text Available Annual ryegrass is a temperate climate annual foraging grass, grown mostly in the South of Brazil, especially in the state of Rio Grande do Sul. Despite its importance, little is known about its genetic diversity, both within and among the populations cultivated. This knowledge is of fundamental importance for developing breeding and conservation strategies. The aim of this study was to characterize the genetic diversity and structure of four populations of annual ryegrass. Three of the populations were located in Rio Grande do Sul and the fourth in Uruguay. RAPD markers were used to study the genetic diversity and structure of these populations. Analysis of 375 individuals sampled from the populations, using six RAPD primers, generated a total of 82 amplified bands. They included 73 polymorphic bands (89,02%. The value of the total genetic diversity index obtained, (0,71 was high, indicating the presence of wide genetic diversity in the four populations. Genetic structure analysis revealed that 98% of total diversity is intrapopulational, whereas interpopulational genetic diversity was only 2%. These results suggest that before these populations separated, they had gone through a period of gene exchange and, even after the separation event, gene frequency stayed at levels similar to the original levels, with no differential selection for these genes in the different cultivation areas.O azevém anual é a gramínea anual forrageira de clima temperado de maior utilização no sul do Brasil, particularmente no Estado do Rio Grande do Sul. Apesar de toda a importância que a espécie apresenta, pouco se conhece a respeito da diversidade genética presente entre e dentro das populações cultivadas. Este conhecimento é de fundamental importância para o estabelecimento das estratégias de melhoramento genético e de conservação destes materiais.

Silva, Luiz Sérgio; Pinheiro, Tarcísio Márcio Magalhães; Sakurai, Emília

2007-12-01

Restructuring of the Brazilian financial sector was consolidated through the combination of mass lay-offs, automation, and outsourcing, in addition to business re-engineering with leveling of hierarchical echelons, labor casualization, and multi-function jobs. In order to comply and deal with the new demands, bank employees had to increase their schooling, become multi-functional and expert sales attendants, and submit to substandard conditions in the workplace, increased workload, overtime, and low wages. The purpose of the current study was to examine the restructuring process in a state-owned bank in Minas Gerais State, Brazil, and its impacts on workers' health. The study also analyzes absenteeism rates from 1998 to 2003, when there was an increase in diseases such as repetitive stress injury (RSI)/work-related musculoskeletal disorders (WRMD) and mental/behavioral disorders, accounting for 56% and 19% of sick leaves. The process has continued to the present, with a restrictive recruitment policy. Further study is needed to confirm the results.

Full Text Available O presente artigo pretende realizar uma análise do ensino jesuítico implementado no período colonial brasileiro e demonstrar que a estrutura escolar fundada pelos padres jesuítas no Brasil era adequada para o momento histórico vivenciado, levando-se em consideração quatro aspectos: os objetivos do Projeto Português para o Brasil; o projeto educacional Jesuítico; a própria estrutura social brasileira da época; e o modelo de homem necessário para a época Colonial. Os jesuítas, com seu Projeto Educacional, e os portugueses que vieram para a colônia brasileira em busca de riquezas, tiveram papel fundamental na formação da estrutura social, administrativa e produtiva da sociedade que estava sendo formada. Partindo do pressuposto de que o fenômeno educacional não é um fenômeno independente e autônomo da realidade social de determinado momento histórico, devemos analisar o projeto jesuítico levando-se em conta o desenvolvimento social e produtivo da época colonial. Assim, pode-se supor que o modelo educacional proposto pelos jesuítas, que pretendia formar um modelo de homem, baseado nos princípios escolásticos, era coerente com as necessidades e aspirações de uma sociedade em formação na primeira fase do período colonial brasileiro.Jesuit teaching in Brazil during the colonial period is analyzed. It may even be proved that the schooling structure established by the Jesuit fathers was extremely adequate for that specific historical period. Four aspects may be taken into account: the aims of the Portuguese Project for Brazil; the Jesuit Educational Project; the Brazilian social structure at that time; and the human model needed for the colonial period. The Jesuits' Educational Project and the Portuguese colonizers that came to the colony in search of wealth have an important role in the formation of the social, administrative and productive structure of a society in constant evolution.

Concepta McManus

Full Text Available Movement of livestock production within a country or region has implications for genetics, adaptation, well-being, nutrition, and production logistics, particularly in continental-sized countries, such as Brazil. Cattle production in Brazil from 1977 to 2011 was spatialized, and the annual midpoint of production was calculated. Changes in the relative production and acceleration of production were calculated and spatialized using ARCGIS®. Cluster and canonical discriminant analyses were performed to further highlight differences between regions in terms of cattle production. The mean production point has moved from the Center of Minas Gerais State (in the southeast region to the North of Goiás State (in the Midwest region. This reflects changes in environmental factors, such as pasture type, temperature and humidity. Acceleration in production in the northern region of Brazil has remained strong over the years. More recently, "traditional" cattle-rearing regions, such as the south and southeast, showed a reduction in growth rates as well as a reduction in herd size or internal migration over the period studied. These maps showed that this movement tends to be gradual, with few regions showing high acceleration or deceleration rates.

Full Text Available The geographic distribution of cutaneous leishmaniasis (CL makes it a disease of major clinical importance in Brazil, where it is endemic in the state of Paraná. The objective of this study was to analyze the spatial distribution of CL in Paraná between 2001 and 2015, based on data from the Sistema de Informação de Agravos de Notificação (Information System for Notifiable Diseases regarding autochthonous CL cases. Spatial autocorrelation was performed using Moran's Global Index and the Local Indicator of Spatial Association (LISA. The construction of maps was based on categories of association (high-high, low-low, high-low, and low-high. A total of 4,557 autochthonous cases of CL were registered in the state of Paraná, with an annual average of 303.8 (± 135.2 and a detection coefficient of 2.91. No correlation was found between global indices and their respective significance in 2001 (I = -0.456, p = 0.676, but evidence of spatial autocorrelation was found in other years (p< 0.05. In the construction and analysis of the cluster maps, areas with a high-high positive association were found in the Ivaí-Pirapó, Tibagi, Cinzas-Laranjinha, and Ribeira areas. The state of Paraná should keep a constant surveillance over CL due to the prominent presence of socioeconomic and environmental factors such as the favorable circumstances for the vectors present in peri-urban and agriculture áreas.

This article discusses the achievements and challenges that England and Brazil face in relation to their capacity to address inequalities in health through health promotion and public health policies. Using secondary data (policy texts and related documents), this article contextualizes, explains, and critically appraises health promotion and public health efforts for the reduction of inequalities in health in the 2 countries. A historic documentary analysis was undertaken, with hermeneutics as the methodological framework. The global economic crisis has prompted the so-called developed economies of Europe to reconsider their economic and social priorities. England represents a state facing this kind of challenge. Equally, Brazil is assuming new positions not only on the world stage but also in terms of the relationship it has with its citizens and the priorities it has for state welfare. The United Kingdom continues to finance a health care system allowing universal access in the form of the National Health Service, and state concern about the public health task of reducing inequalities has recently been underlined in policy. For Brazil, although there have been recent achievements related to population access to healthcare, challenges continue, especially with regard to the quality of care. © SAGE Publications 2015.

Full Text Available O objetivo do estudo é identificar os determinantes da folga organizacional em uma empresa com estrutura descentralizada, com ênfase no modo como os controllers das unidades de negócios afetam a folga. Foi realizada uma pesquisa descritiva com abordagem quantitativa, por meio de survey, utilizando o instrumento de pesquisa concebido por Indjejikian e Matëjka (2006, que se constitui de dois questionários, um para o gestor e outro para o controller de cada UN. A empresa objeto de estudo apresenta estrutura descentralizada com 45 UNs, das quais 32 responderam aos questionários. Os resultados da pesquisa indicam que as metas de desempenho, quando o crescimento das UNs é provocado pelo aumento das vendas e do market share, com sacrifício do retorno sobre o investimento no curto e médio prazos, são mais fáceis de alcançar e permitem maior folga organizacional do que em situações de UNs mais estáveis. Também indicam que a folga organizacional é maior em ambientes caracterizados por maior assimetria de informação entre a holding e os gestores das UNs, definidos pelo foco do controller da UN. Os resultados dos testes da relação entre as variáveis foco do controller da UN e folga organizacional evidenciam que os controllers das UNs priorizam o apoio à tomada de decisão na UN, em detrimento de suas responsabilidades com o sistema de controle gerencial corporativo. Quanto maior o tempo de atuação do controller na UN, maior é a sua dedicação às responsabilidades relacionadas à gestão da UN em detrimento do foco nas tarefas da holding. Conclui-se que a relação constatada nesta pesquisa entre o nível de folga organizacional e o foco dos controllers das UNs se coaduna com aquela enunciada no estudo de referência. De maneira geral, os resultados das análises estão alinhados com os da pesquisa de Indjejikian e Matëjka (2006, consideradas as limitações de comparabilidade em função das diferenças amostrais.

Full Text Available Closed television in Brazil: identity and alienation — This article questions the explicative effectiveness of the idea of entertainment in today's mediatic environment, particularly in Brazil's cable TV programs. This idea of entertainment obfuscates formative processes of values, identities, quotidian experience, learning, and the standardization of lifestyles in the complex and dynamic structure of the diverse genres of current television productions that are watched by large audiences. Understanding these programs and their performative logic requires the appropriation of a sophisticated range of concepts that can clarify the terms of their structure and effectiveness among cable TV subscribers. The semantic, theoretical and explicative field in which cable TV was conceived has already been superseded since the Frankfurtian critique, French semiology, reception studies, and especially the sociology developed by cultural studies. The latter studies offer new ways of viewing this subject, which go beyond the theoretical field where the idea of entertainment was heretofore widely accepted. O objetivo central deste ensaio é questionar a eficácia explicativa da noção de entretenimento no ambiente midiático contemporâneo, em particular nas programações da televisão fechada no Brasil. A noção de entretenimento obscurece processos formativos de valores, identidades, de objetivação da experiência cotidiana e de aprendizado e padronização de estilos de vida presentes na complexa e dinâmica estrutura dos diversos gêneros presentes nas atuais produções televisivas de expressiva audiência no ambiente da televisão fechada no Brasil. O entendimento dessas produções e de sua lógica performativa requer a apropriação de um leque sofisticado de conceitos cujos atributos esclarecem os termos de sua estruturação e eficácia junto ao público assinante.

Full Text Available Epstein-Barr virus (EBV is a ubiquitous herpesvirus, and most people have serological evidence of previous viral infection at adult age. EBV is associated with infectious mononucleosis and human cancers, including some lymphomas and gastric carcinomas. Although EBV was first reported in lymphoepithelioma-like gastric carcinoma, the virus was also found in conventional adenocarcinomas. In the present study, 53 gastric carcinomas diagnosed in São Paulo State, Brazil, were evaluated for EBV infection by non-isotopic in situ hybridization with a biotinylated probe (Biotin-AGACACCGTCCTCACCACCC GGGACTTGTA directed to the viral transcript EBER-I, which is actively expressed in EBV latently infected cells. EBV infection was found in 6 of 53 (11.32% gastric carcinomas, mostly from male patients (66.7%, with a mean age of 59 years old. Most EBV-positive tumors were in gastric antrum. Two EBV-positive tumors (33.3% were conventional adenocarcinomas, whereas four (66.7% were classified as lymphoepithelioma-like carcinomas. EBV infection in gastric carcinomas was reported elsewhere in frequencies that range from 5.6% (Korea up to 18% (Germany. In Brazil, a previous work found EBV infection in 4 of 80 (5% gastric carcinomas, whereas another study found 4.7 and 11.2% of EBV-positive gastric carcinomas of Brazilians of Japanese origin or not, respectively. In the present study, the frequency of EBV-positive gastric carcinomas is similar to that reported in other series, and the clinicopathologic characteristics of these EBV-positive tumors are in agreement with the data in the literature.

Background Brazil recently approved synthetic phosphoetanolamine, a popularly dubbed 'cancer pill', a substance that has been shown to kill cancer cells in lab animal models but was not yet formally accessed in humans, and thus despite the existence of any evidence of its efficacy and safety. Methods The authors describe the recent decision of Brazil to aprove phosphoetanolamine in the context of growing 'judicialization' to promote access to medicines and thus reinforcing a growing sense of legal uncertainty. Results The approval of phosphoetanolamine despite the existence of any evidence of its efficacy and safety represents to the authors one of the saddest and surrealistic episodes in Brazil's recent public health history. Brazil's current economic crisis is fueling the 'judicialization' to promote access to medicines and thus reinforcing a growing sense of legal uncertainty in the context of rising economic constrains and a progressive failing state. The authors state that the Phosphoetanolamine's approval bill violates current legal prohibition of commercialisation of drugs without the Brazilian national drug regulatory agency's approval and thus may represent a potential menace to Brazil's pharmacogovernance and the country's governance to health technology assessment at the Brazilian national health systems. Conclusion Phosphoetanolamine's approval illustrates that the combination of flawed decision making, economic crisis and political interference may threaten weak governance mechanisms for drug regulation and health technology assessment and thus representing an extra burden in the sustainability of universal access-based national health systems.

Full Text Available Short-term variability of nutrients, chlorophyll-a (Chl-a and seston (TSS concentrations were followed up at a fixed station in the Bertioga Channel (BC, Southeastern Brazil, over two full tidal cycles of neap and spring tides, during the winter of 1991. Simultaneous data on hydrographic structure, tidal level and currents allowed the computation of the net transport of those properties. Tidal advection and freshwater flow were the main forcing agents on the water column structure, nutrient availability and Chl-a distribution. Dissolved inorganic nitrogen and phosphate average values were high (16.88 and 0.98 ¼M, respectively, at neap tide and 10.18 and 0.77¼M at spring tide. Despite N and P availability, Chl-a average values were low: 1.13 in the neap and 3.11 mg m-3 in the spring tide, suggesting that the renovation rate of BC waters limits phytoplankton accumulation inside the estuary. The highest Chl-a was associated with the entrance of saltier waters, while the high nutrient concentrations were associated with brackish waters. Nutrients were exported on both tides, TSS and Chl-a were exported on the spring tide and Chl-a was imported on the neap tide. The study of the main transport components indicated that this system is susceptible to the occasional introduction of pollutants from the coastal area, thus presenting a facet of potential fragility.Variações de curta escala das concentrações de nutrientes, clorofila-a (Cl-a e séston foram acompanhadas em uma estação fixa no canal de Bertioga (CB, sudeste do Brasil, em dois ciclos completos de maré de quadratura e sizígia, no inverno de 1991. Dados simultâneos da estrutura hidrográfica, marés e correntes permitiram calcular o transporte resultante daquelas propriedades. A advecção por maré e o fluxo de água doce foram as principais forçantes da estrutura hidrográfica e da distribuição de nutrientes e Cl-a. As concentrações médias de NID e fosfato foram altas

The occurrence of American visceral leishmaniasis in the State of Espírito Santo, Brazil has always been associated with the presence of the Lutzomyia longipalpis vector. The geographic distribution of this vector in this state is related to the presence of specific geoclimatic characteristics, such as a dry climate, low elevations (longipalpis. Sand flies were captured monthly from July 2006 to August 2007 using Shannon and CDC traps in two municipalities with records of autochthonous American visceral leishmaniasis and one with no record. We captured 13,112 sand flies, but no Lu. longipalpis was found. The absence of Lu. longipalpis and the possible role of another American visceral leishmaniasis vector in these localities were discussed.

The data presented here have been collected in the southern part of the Atlantic Forest (Mata Atlântica) in the state of Paraná, Brazil within a bilateral scientific project (SOLOBIOMA). The project aimed to assess the quality of secondary forests of different regeneration stages in comparison with old-growth forests with regard to diversity of soil animals and related functions. The Atlantic Forest is a hotspot of biological diversity with an exceptionally high degree of endemic species, extending over a range of 3,500 km along the coast of Brazil. The anthropogenic pressure in the region is very high with three of the biggest cities of Brazil (São Paulo, Rio de Janeiro, and Curitiba) lying in its extension. An evaluation of the value of secondary forests for biodiversity conservation is becoming more and more important due to the complete disappearance of primary forests. In 2005, we sampled spiders in 12 sites of three successional stages (5-8, 10-15, 35-50 yr old, three replicates of each forest stage) and old-growth forests (> 100 yr untouched, also three replicates). All sites were inside a private nature reserve (Rio Cachoeira Nature Reserve). We repeated the sampling design and procedure in 2007 in a second private reserve (Itaqui Nature Reserve). The two nature reserves are within about 25 km of each other within a well preserved region of the Mata Atlântica, where the matrix of the landscape mosaic is still forest. A widely accepted standard protocol was used in a replicated sampling design to apply statistical analyses to the resulting data set and allow for comparison with other studies in Brazil. Spiders were sorted to family level and counted; the adult spiders further identified to species if possible or classified as morphospecies with the help of several spider specialists. © 2017 by the Ecological Society of America.

Full Text Available The higher education system in the state of Bahia, Brazil, comprises four universities offering, altogether, several undergraduation and graduation courses, in a number of areas. The system configuration is around 20 years old, but the colleges which gave rise to it were structured back in the late sixties. The aim of this study is to highlight the teacher training role in the system formation. Also, it is presented a discussion on the possibilities and limitations originated from the teacher training colleges in the higher education democratization process. The conclusion is that, although the teacher training courses have been the driving force of the higher education system in Bahia for more than 40 years, the number of vacancies offered by the course is not sufficient to equate the historical problem regarding the lack of titled teachers in the state.

Uranium isotopes in groundwater occurring at Amazonas State, Brazil

2015-01-01

This paper reports the behavior of the dissolved U-isotopes 238 U and 234 U in groundwater providing from 15 cities in Amazonas State, Brazil. The isotope dilution technique accompanied by alpha spectrometry were utilized for acquiring the U content and 234 U/ 238 U activity ratio (AR) data, 0.01–1.4 µg L −1 and 1.0–3.5, respectively. These results suggest that the water is circulating in a reducing environment and leaching strata containing minerals with low uranium concentration. A tendency to increasing ARs values following the groundwater flow direction is identified in Manaus city. The AR also increases according to the SW–NE directions: Uarini→Tefé; Manacapuru→Manaus; Presidente Figueiredo→São Sebastião do Uatumã; and Boa Vista do Ramos→Parintins. Such trends are possibly related to several factors, among them the increasing acid character of the waters. The waters analyzed are used for human consumption and the highest dissolved U content is much lower than the maximum established by the World Health Organization. Therefore, in view of this radiological parameter they can be used for drinking purposes. - Highlights: • U-isotopes data in important aquifer systems in Amazon area. • Application of the U-isotopes data to investigate the groundwater flow direction. • Evaluation of the drinking-water quality in terms of dissolved uranium

Full Text Available Abstract This study reports the pathogen Perkinsus beihaiensis in oysters of the genus Crassostrea on the coast of the State of Bahia (Brazil, its prevalence, infection intensity and correlation with salinity. Oysters (n = 240 were collected between October and December 2014 at eight sampling stations between latitudes 13°55'S and 15°42'S. The laboratory procedures included macroscopic analysis, histology, culture in Ray's fluid thioglycollate medium (RFTM, Polymerase Chain Reaction (PCR and DNA sequencing. PCR and sequencing have been used for the genetic identification of oysters as well. Two species of oysters have been identified: Crassostrea rhizophorae and C. brasiliana. In both oyster species P. beihaiensis was the only Perkinsus species detected. In C. rhizophorae, the average prevalence was 82.8% by histology and 65.2% by RFTM. In C. brasiliana, the prevalences were 70.5% and 35.7%, respectively. The higher prevalence of P. beihaiensis in C. rhizophorae was probably influenced by salinity, with which was positively correlated (r> 0.8. In both oysters, P. beihaiensis was located mainly in the gastric epithelium. The infection was generally mild or moderate, without apparent harm to the hosts, but in cases of severe infection, there was hemocytical reaction and tissue disorganization. The generally high prevalence in the region suggests that oysters should be monitored with respect to this pathogen, especially in growing areas.

Full Text Available The aim of this research was to diagnose the socioeconomic conditions of cheese producers from three municipalities of Marajó Island, Pará state, Brazil. Manufacture process, hygienic-sanitary conditions in handmade cheese production and its commercialization were some features analysed for both cream-type and butter-type cheeses. During the survey, conducted from March to September 2012 questionnaires were applied to ten Marajó’s cheese producers. The cheese fabrication was characterized as a handmade process, employing family labor, most over ten years of experience. The production has a small scale, uses rudimentary technologies, lacks proper infrastructure for the processing of the product and has unsatisfactory hygienic-sanitary conditions. Commercialization is mainly by direct sale on the ship that travels to Belém city, capital of Pará state. Interviewed producers showed good reception to knowledge that can improve quality of the product, but they need a better guidance. In this context, the transfer of information is essential to sustain the production of these cheeses and preserve local culture, contributing to the economic and social development of producers regions.

Full Text Available This paper focuses on fresh fish trade networks found in the street markets of Palmas, capital of Tocantins state, Brazil, so as to identify the economic agents involved and the various geographical spaces which interact as a result of these networks. Fresh fish trade in Palmas takes place in distributor warehouses, grocery stores, supermarkets and hypermarkets, fish shops, and fishing communities, but it is street markets that constitute the most popular sale venues. Market sellers establish upstream supply networks with sectors in the fish food system (suppliers in primary and secondary production, distribution, and retail, whose interactions generate connections in Palmas (fishermen, distributors, retailers on a local scale, as well as connections with locations in Tocantins and Pará states (fishermen, fisheries, cold storage companies on a regional scale. Sellers also establish downstream trade networks with the end consumer at markets and with establishments in the food and small retail sectors, whose interactions produce mostly local connections, in Palmas and in the Luzimangues district (close to Palmas. Such connections are marked by consumption processes in these urban areas. Key-words: network, fresh fish trade, street markets.

2001-01-01

Full Text Available This work investigated the effect of repeated applications on enhanced degradation of metalaxyl in two different agricultural soils used for cultivation of orange and lemon from Casa Branca and Itapetininga districts of São Paulo State, Brazil. Soil samples were collected from areas repeatedly treated with commercial ridomil 50GR for six successive years, and from other areas never exposed to this fungicide. At the laboratory, soil samples received a 14C-metalaxyl solution and its degradation was studied through radiometric techniques to measure biomineralization and recovery of extractable- and soil-bound products. Enhanced degradation was verified only in one soil, although partial degradation and mineralization of the fungicide were detected in both soils. The different rates and patterns of metalaxyl degradation in the soils were probably due to their different physical, chemical, and biological characteristics.

Mayra Araguaia Pereira Figueiredo

Full Text Available The states that make up the Legal Amazon Region, which include the state of Maranhão, account for 99% of registered cases of human malaria in Brazil. It is also believed that transmission of malaria from nonhuman primates (NHP to humans occurs in this region, because of current reports of seroepidemiological results from samples from humans and NHP coexisting in the same areas. This study aimed to make morphological, serological and molecular diagnoses of Plasmodium spp. in neotropical primates on the island of São Luís, state of Maranhão, Brazil. The diagnostic techniques used were optical microscopy, the polymerase chain reaction (PCR and the indirect immunofluorescence assay (IFA. From June 2009 to April 2010, 70 NHP were sampled: 50 at the Wild Animal Screening Center (CETAS, located in the municipality of São Luís and 20 free-living individuals that were caught in a private reserve located in the municipality of São Jose de Ribamar, state of Maranhão. Under an optical microscope, 140 slides (two from each animal were evaluated and five animals (7.1% were found to be positive. IFA did not detect anti-Plasmodium spp. From PCR on the 70 animals sampled, amplified Plasmodium spp. products were observed in 13 samples, of which eight (61.5% were from free-living animals and five (38.5% were from animals at CETAS.

Full Text Available AbstractThe structure of forests, the three-dimensional arrangement of individual trees, has a profound effect on how ecosystems function and carbon cycle, water and nutrients. Repeated optical satellite observations of vegetation patterns in two-dimensions have made significant contributions to our understanding of the state and dynamics of the global biosphere. Recent advances in Remote Sensing technology allow us to view the biosphere in three-dimensions and provide us with refined measurements of horizontal as well as vertical structure of forests. This paper provides an overview of the recent advances in fusion of optical and radar imagery in assessing terrestrial ecosystem structure and aboveground biomass. In particular, the paper will focus on radar and LIDAR sensors from recent and planned spaceborne missions and provide theoretical and practical applications of the measurements. Finally, the relevance of these measurements for reducing the uncertainties of terrestrial carbon cycle and the response of ecosystems to future climate will be discussed in details.

Full Text Available Eighteen Trypanosoma cruzi stocks from the state of Paraíba, Brazil, isolated from man, wild mammals, and triatomine bugs were studied by multilocus enzyme electrophoresis and random primed amplified polymorphic DNA. Despite the low number of stocks, a notable genetic, genotypic, and phylogenetic diversity was recorded. The presence of the two main phylogenetic subdivisions, T. cruzi I and II, was recorded. The strong linkage disequilibrium observed in the population under survey suggests that T. cruzi undergoes predominant clonal evolution in this area too, although this result should be confirmed by a broader sample. The pattern of clonal variation does not suggests a recent origin by founder effect with a limited number of different genotypes.

Lagoa de Araruama in the state of Rio de Janeiro, Brazil, is a hypersaline lagoon with salinity varying spatially from 45 to 56. We collected water samples during monthly cruises throughout the lagoon, and along the streams feeding the system, from April 1991 to March 1992. Nutrients and other water quality parameters exhibited great spatial and temporal variations. Mass balance calculations indicate large amounts of anthropogenic nutrient inputs. The data indicate that the lagoon currently is oligotrophic but is in a state of transition to become a mesotrophic system. Molar dissolved inorganic nitrogen:dissolved inorganic phosphorus (DIN/DIP) varied between 2.2:1 and 659:1 with a volume-weighted average of 22:1. The high DIN/DIP ratio contrasts with that found in nearby lagoons, suggesting that phytoplankton primary production is limited by phosphorus in Lagoa de Araruama. The major loss of DIP is apparently driven by biological assimilation and diagenic reactions in the sediments. Calculations indicate that the lagoon is slightly net autotrophic at +0.9 mol C m -2 yr -1. This suggests that the biomass of the primary producers is restricted by phosphorus availability. Phosphorus retention in the sediment and the hypersaline state of the lagoon prevent changes in autotrophic communities and the formation of eutrophic conditions.

Effect of coastline properties and wastewater on plankton composition and distribution in a stressed environment on the north coast of Olinda-PE (Brazil

Full Text Available A study of the structure of the plankton community along the coastal zone of the Casa Caiada-Rio Doce area (Pernambuco, Brazil is presented. The results obtained indicated that in the protected zones the water presented high turbidity, high temperature, low salinity and high nutrient and oxygen rates. All of these conditions were responsible for the reduction in plankton diversity and an increase in the biomass of the most opportunistic (r-strategist species e.g. Gyrosigma balticum and Bacillaria paxillifera (Phytoplankton and Euterpina acutifrons (Zooplankton. The differences found with respect to others area studies performed in pristine conditions indicated that plankton structure could be used as an environmental health indicator and that, in this specific area, it was indicative of a poor quality coastal environment.Foi realizado um estudo sobre a estrutura das comunidades planctônicas ao longo das praias de Casa Caiada e Rio Doce (Pernanbuco, Brasil. A área de estudo sofre grande influência antrópica onde as condições ambientais são controladas pela presença de estruturas costeiras, reduzindo a intensidade da circulação neste ambiente; e pelos efluentes clandestinos de esgoto que aportam águas poluídas para dentro do sistema protegido. Os resultados obtidos indicam que nas zonas protegidas as águas apresentam alta turbidez, temperaturas elevadas, salinidades reduzidas e altas concentrações de nutrientes e oxigênio. Estas condições são responsáveis pela redução da diversidade do plâncton e pelo aumento da biomassa das espécies mais resistentes. As diferenças registradas com respeito a áreas similares, porém não impactadas, parecem indicar que a estrutura planctônica pode ser usada como um indicador da qualidade ambiental, sugerindo uma baixa qualidade das praias em estudo.

In order to estimate the prevalence of influenza like illness (ILI) in adults from all state capitals and geographic regions in Brazil, a periodical monitoring of ILI cases by the national telephone survey (VIGITEL) was carried out in 2010. A cross-sectional study with 47,876 telephone interviews in the state capitals and Federal District, a probabilistic sample of adult population (>18 years-old) with landline telephone. Questions concerning the results of ILI cases and pandemic influenza (H1N1) 2009, from January 10 to November 30, were analyzed. The proportion of cases stratified by sociodemographic characteristics and Brazilian geographic region was weighted with data from the National Survey with Household Sampling (PNAD) 2008. The prevalence of ILI cases in the last 30 days before interview was 31.2% (95%CI 30.2-32.2%) for all state capitals and the Federal District. This prevalence was higher among women, young adults (18 to 29 years-old) and individuals with 9 to 11 years of schooling. According to the geographic region analysis, Northern Brazil presented the highest prevalence of ILI cases. A tendency to increase with further decrease was observed among the geographic regions, except the Northeast. Need for health care assistance was reported by 26.8% (95%CI 25.1-28.5) from ILI cases. Among ILI cases that sought health care assistance, 2.6% (95%CI 1.8-3.4) reported pandemic influenza (H1N1) 2009 medical suspicion. The results of this survey supported influenza surveillance as it provided timeliness and useful surveillance information, which were not captured by the traditional surveillance system, as the occurrence of ILI and need of health care assistance.

Roberto de Sousa Miranda

Full Text Available Nosso objetivo é compreender as relações entre a base do Movimento dos Trabalhadores Rurais Sem Terra (MST e suas lideranças, tomando como elemento de mediação a estrutura organizacional formalmente adotada em 2003. Para tanto, três chaves analíticas são utilizadas: Clastres, que explora a ideia de estrutura separada do corpo social; Leach, que opõe um modelo abstrato de organização às situações práticas observadas e interpretadas a partir da materialidade do comportamento dos assentados e acampados; o Neo-institucionalismo, que trata as instituições enquanto regras e normas que regulamentam a vida social. As análises foram baseadas em observações realizadas no XII Encontro Estadual do MST na Paraíba e nos assentamentos rurais José Antonio Eufrosino e Osiel Pereira, localizados no município de Campina Grande. Recusando as abordagens que tentam medir o grau de adoção dos modelos organizacionais formais pelos grupos sociais, tentamos revelar as incongruências produtoras das dinâmicas de reestruturação da organização do MST.

Full Text Available Due to the violent expropriation and commercialization of large areas in the state of Paraná, Brazil, at the beginning of the 20th century the surviving indigenous groups were herded within small parcels of land, called villages, and currently denominated Indigene Land (IL. The Nhandewa Guarani of the northern region of the state of Paraná, living in the Laranjinha, Ywyporã and Pinhalzinho ILs, have experienced terrible conditions since they lost many of their traditions and culture, including their language. During the 1980s and 1990s and within the context of the world economic crisis, the international organisms UNESCO and World Bank aimed at social cohesion and started, as a joint venture with the national states, the implementation of an inclusion policy based on the right to be different. Current analysis discusses the results of a cultural revival project developed through the register of narratives by the indigene elderly people with regard to the Nimongarai baptism ritual and pedagogical interventions in schools in the state of Paraná.

Full Text Available Garlic is a vegetable that has economic and social relevance in Brazil. Rio Grande do Norte is among the consumer states, however, despite having regions with favorable conditions for growing garlic, it depends on imports of this product to meet its demand. The introduction of cultivars that have high yield and quality, and the adjustments in vernalization technology, which is a key issue for adaptation of new cultivars, are mechanisms that can contribute to garlic revitalization in areas previously producing this vegetable. Therefore, the objective of this work was to assess the quality characteristics of semi-noble garlic cultivars subjected to different bulb-seed pre-planting vernalization periods in two counties of the Western Mesoregion of Rio Grande do Norte State (RN, Brazil. Two experiments were simultaneously conducted in Barauna RN and Governador Dix-sept Rosado RN, from April to November, 2012. A complete randomized block experimental design was used with four replications. The treatments were arranged in split-plot design, with the plots consisted of cultivars (Gigante-do-Nucleo and BRS-Hozan and subplots consisted of bulb-seed pre-planting vernalization (4±1°C periods (0, 10, 20 and 30 days. The evaluations consisted of bulb diameter, pH, titratable acidity, soluble solids, total soluble sugars, reducing sugars, pungency, total solids and industrial index. The use of 10-day bulb-seed pre-planting vernalization increased the semi-noble garlic quality produced in Barauna and Governador Dix-sept Rosado. The cultivars Gigante-do-Nucleo and BRS-Hozan presented good prospects for industrialization, with good characteristics of flavor and aroma.

Many water-supply systems in South America utilize the waters of the Guarani aquifer at least as part of their networks. However, there is little present knowledge in Brazil of the factors affecting Rn presence in the water supplied for end-users, despite the economic importance of Guarani aquifer. 222 Rn analyzes of 162 water samples were performed at 8 municipalities in Sao Paulo State, Brazil, with the aim of investigating the major factors affecting its presence in solution. The 222 Rn activity concentration ranged from 0.04 up to 204.9 Bq/L, with three samples exceeding the World Health Organization maximum limit of 100 Bq/L. Aeration was confirmed as the most important factor for Rn release, as expected due to its gaseous nature. Accumulation in pipes and stratification in the water column were other significant factors explaining the data obtained in some circumstances. The Rn daughters 214 Pb and 214 Bi were also determined in a set of selected samples and their presence was directly related to the occurrence of Rn dissolved in water

Full Text Available Population structure of the lancelet Branchiostoma caribaeum Sandevall, 1853 was studied in four surveys, corresponding to austral seasons, in a tropical bay, southeast of Brazil. Abundance was higher in the spring and was positively correlated to coarse sediments, limiting its occurrence to some sectors of the sampling area. Body length and biomass differed seasonally but not between sexes. Sexually mature individuals occurred in all seasons, suggesting continuous breeding that is typical of tropical species. Variation in the frequency of small specimens indicates temporal differences in the intensity of breeding. The body length of recruits differed from other population of lancelets and the small length which B. caribaeum attained sexual maturity in Guanabara Bay may be related to local environmental stress or the great availability of food.A estrutura populacional do anfioxo Branchiostoma caribaeum Sandevall, 1853 foi analisada em quatro campanhas abrangendo todas as estações do ano, na Baía de Guanabara, sudeste do Brasil. A abundância de indivíduos foi maior na primavera e positivamente correlacionada com sedimentos grossos, tendo sua distribuição limitada a alguns setores da área amostral. O tamanho corpóreo e a biomassa diferiram sazonalmente, mas não entre os sexos. Indivíduos sexualmente maduros ocorreram em todas as estações do ano, sugerindo uma reprodução contínua, típica de espécies tropicais. Variações na freqüência de ocorrência de espécimes pequenos indicaram diferenças temporais na intensidade da reprodução. O tamanho corpóreo dos recrutas diferiu de populações de anfioxos de outros locais. O menor tamanho em que B. caribaeum atinge a maturidade sexual na Baía da Guanabara pode estar relacionada ao estresse ambiental ou à grande disponibilidade de alimento do local.

Full Text Available Background: Mortality from breast cancer decreased in high-income countries, while countries with middle and low incomes as Brazil still has upward trend. However, large geographical variations among the federal units are observed in the country. The aim of the study was to evaluate the trend of specific mortality from breast cancer in women over 20 years old years among different states of Brazil from 1996 to 2012.  Methods and Findings: Ecological study, using linear regression model for temporal analysis of specific mortality coefficient from malignant neoplasm of breast. We also checked the degree of its correlation with the HDI for the states of Brazil during the stated period. There was an increase in the specific mortality rate for malignant neoplasm of the breast in order of 33%, with range from 23.2 to 30.8 / 100,000 inhabitants. The states with the highest human development HDI in 2010, showed the largest specific mortality rates of breast cancer. Conclusion: Taking the trends of mortality from cancer an important role, this study confirms the need for improvements in mammography coverage, following radiological lesions suspected and access to appropriate therapy.

Genetic variability of cassava (Manihot esculenta Crantz) in Brazil is wide, being this the result of natural and cultural selection during pre- and post-domestication of the species in different environments. Given the number of species of the genus found in the region (38 of a total of 98 species), the central region of Brazil was defined as the primary center of cassava diversity. Therefore, genetic diversity characterization of cassava accessions is fundamental, both for farmers and for plant breeders, because it allows the organization of genetic resources and better utilization of available genetic diversity. This research aims to assess genetic divergence of cassava accessions from the south-central region of the State of Mato Grosso, based on multi-categorical morphological traits. For this purpose, 38 qualitative and quantitative morphological descriptors were used. Genetic diversity was expressed by the genetic similarity index, with subsequent clustering of accessions by the modified Tocher's procedure and UPGMA. Of 38 descriptors, only growth habit of stem showed no variability. Tocher and UPGMA methods were efficient and corroborated on group composition. Both methods were able to group accessions of different localities in distinct group consistency.

The Mini-Mental State Examination (MMSE) is the most widely used cognitive screening test around the world. In Brazil, different MMSE versions and many cut-off points have been used. A systematic review of papers indexed in Scielo was conducted in order to analyze use of the MMSE in Brazilian empirical studies with elderly people. To search for these texts, the complete name of the instrument and its abbreviation were used. A growth trend in the scientific production during the 1998 to 2013 period was observed. Eleven versions of the MMSE were identified and the Bertolucci et al. version was the most cited. Over half of the studies used schooling as the criteria to establish cut-off points. The studies were predominantly conducted using samples recruited from large cities in the Southeastern region and in the community. Despite the growing trend of research with the elderly using the MMSE, the psychometric properties of this scale of measurement have been the subject of little investigation. Despite the widespread use of the MMSE in Brazil, there is a lack of standardization and evidence of validity for this this scale of measurement.

Visceral leishmaniasis (VL) is endemic in Belo Horizonte (State of Minas Gerais, Brazil). Leishmania sp. can naturally infect several species of mammals, and the domestic dog is the most important reservoir of the disease in South America. This report describes five cases of visceral leishmaniasis in Brazilian canids. Among 15 animals kept in captivity in a zoo in Belo Horizonte (State of Minas Gerais, Brazil), two animals, a bush dog (Spheotos venaticos) and a hoary zorro (Lycalopex vetulus) were serologically positive and developed clinical signs of VL, whereas three other canids, including a crab-eating fox (Cerdocyon thous), a maned wolf (Chrysocyon brachyurus), and a hoary zorro (Lycalopex vetulus) had positive serological results without clinical signs.

Full Text Available Pesquisas sobre estrutura de capital das empresas são consideradas dentre as mais relevantes na área de finanças. Diversas abordagens teóricas têm sido discutidas e testadas na literatura financeira. Este estudo buscou analisar o nível de endividamento das maiores empresas brasileiras, à luz das duas principais teorias que versam sobre o assunto, a teoria de Pecking Order e a teoria de trade--off, testando seus determinantes. A teoria do Pecking Order sugere a existência de uma hierarquia no uso de fontes de recursos, enquanto a teoria de trade-off considera a existência de uma estrutura meta de capital que seria perseguida pela empresa. O estudo é uma adaptação do artigo de Gaud et al. (2005, cujo trabalho serviu como base e principal referência para a escolha das principais variáveis e dos testes econométricos realizados. Tal como Gaud et al. (2005, desenvolvemos as análises estatísticas utilizando a metodologia de Panel Data, que considera os dados da amostra em corte transversal e longitudinal. Além de testes estáticos, foram feitos testes dinâmicos, com o objetivo de analisar o processo de ajuste da estrutura de capital ao longo do tempo, em direção a um suposto nível-alvo ótimo. Os resultados demonstraram relação negativa entre o nível de endividamento das empresas e o grau de tangibilidade dos ativos e a rentabilidade, bem como relação positiva do endividamento com o risco. Demonstraram ainda que empresas de capital estrangeiro são mais endividadas que empresas nacionais. De um modo geral, os resultados sugerem que a teoria de Pecking Order é mais consistente do que a teoria de trade-off para explicar a estrutura de capital das companhias abertas brasileiras. Em especial, destacamos a relação negativa entre endividamento e rentabilidade, confirmando vários outros resultados de pesquisa obtidos na realidade brasileira. A análise dinâmica demonstrou baixa velocidade do processo de ajuste da estrutura de

The objective of this paper is to perform a cross-cultural comparison of gambling disorder (GD) due to electronic gaming machines (EGM), a form of gambling that may have a high addictive potential. Our goal is to investigate two treatment-seeking samples of adults collected in Brazil and the United States, countries with different socio-cultural backgrounds. This comparison may lead to a better understanding of cultural influences on GD. The total studied sample involved 733 treatment-seeking subjects: 353 men and 380 women (average age=45.80, standard deviation ±10.9). The Brazilian sample had 517 individuals and the American sample 216. Subjects were recruited by analogous strategies. We found that the Brazilian sample was younger, predominantly male, less likely to be Caucasian, more likely to be partnered, tended to have a faster progression from recreational gambling to GD, and were more likely to endorse chasing losses. This study demonstrated that there are significant differences between treatment-seeking samples of adults presenting GD due to EGM in Brazil and in the United States. These findings suggest that cultural aspects may have a relevant role in GD due to EGM. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The cultivation of tropical fruit trees has grown considerably in the state of Bahia, northeastern Brazil. Some of these have been severely attacked by phytophagous mites, which are usually controlled by the use of chemical pesticides. However, there is today a growing interest for the adoption of less aggressive measures of pest control, as for example the use of predatory mites. Most of the plant-inhabiting predatory mites belong to the family Phytoseiidae. The objective of this paper is to report the phytoseiid species found in an intensive survey conducted on cultivated tropical fruit trees in fifteen localities of the southern coast of Bahia. Measurements of relevant morphological characters are provided for each species, to complement the understanding of the morphological variation of these species. Twenty-nine species of sixteen genera were identified. A key was elaborated to assist in the separation of these species. Fifteen species are reported for the first time in the state, raising to sixty-six the number of species of this family now known from Bahia. Seventy-two percent of the species collected belong to Amblyseiinae, followed by Typhlodrominae (21%) and Phytoseiinae (7%). The most diverse genus was Amblyseius. Amblyseius operculatus De Leon was the most frequent and abundant species. Studies should be conducted to evaluate the possible role of the most common predators as control agents of the phytophagous mites co-occurring with them.

O objetivo desse estudo foi testar a hipótese de que os efeitos de borda afetam alguns parâmetros vegetacionais e populacional em fragmentos de Cerradão no município de Caiapônia, Goiás. Para isso, estudou-se a estrutura da vegetação, o padrão de distribuição espacial de Vernonia aurea Mart. ex DC. (Asteraceae e as condições microclimáticas (temperatura do ar e do solo e umidade relativa do ar em dois ambientes, borda e interior, de três fragmentos de Cerradão com diferentes tamanhos (1,5 ha; 9 ha e 35 ha. Os resultados mostraram uma nítida influência dos efeitos de borda em todos os parâmetros analisados, uma vez que a estrutura da vegetação, o nível de agregação dos indivíduos de V. aurea e os parâmetros microclimáticos foram diferentes entre o interior e a borda dos fragmentos analisados. Esses dados corroboram com outros estudos realizados em diferentes ecossistemas, indicando que a fragmentação dos habitats modifica a composição e estrutura da vegetação, a estrutura espacial e a dinâmica das populações vegetais e, conseqüentemente, animais, podendo levar à extinção de populações locais e redução da diversidade biológica.Edge effects are modifications in the physical, chemical and biological parameters observed in areas of contact of forest fragment with the surrounding environment.

The electoral representation model is insufficient and inadequate for new participatory roles such as those played by members of health councils. This article analyzes representation and representativeness in the Bahia State Health Council, Brazil. The study included interviews with 20 current or former members of the State Health Council, analysis of the council minutes and bylaws, and observation of plenary meetings. Discourse analysis technique was used to analyze interventions by members. The article discusses the results in four analytical lines: the process by which various organizations name representatives to the Council; the relationship between Council members and their constituencies; interest representation in the Council; and criteria used by the plenary to take positions. The study reveals various problems with the representativeness of the Bahia State Health Council and discusses the peculiarities of representation in social participation forums and the characteristics that give legitimacy to representatives.

Full Text Available Estudos relativos às atividades da Controladoria que se inter-relacionam com outras ciências, como Psicologia e Sociologia, favorecem conhecimentos mais holísticos sobre essa área organizacional. Assim, neste estudo objetiva-se verificar os impactos da implantação das normas internacionais de contabilidade na controladoria à luz da Teoria da Estruturação. O pressuposto é que o processo de implantação das normas internacionais vem contribuir para a produção e a reprodução da ordem social da área organizacional controladoria. A Teoria da Estruturação de Giddens (1979; 1996; 2003 sustenta esta pesquisa exploratória, com abordagem qualitativa, realizada por meio de um estudo de caso em uma indústria têxtil. Nela, analisaram-se impactos da implantação das normas internacionais de contabilidade na controladoria, no período de 2008 a 2010, que abrange a fase de implantação dos CPCs na empresa, emitidos pelo Comitê de Pronunciamentos Contábeis (CPC. A coleta de dados deu-se por meio de observação, análise documental, entrevistas individuais e grupo focal. A análise das entrevistas individuais e do grupo focal foi realizada com o auxílio do software Atlas.ti. Os resultados apontaram que o processo de implantação das normas internacionais de contabilidade impactou a estrutura da área organizacional controladoria, por meio de novas atividades, discussões e mudanças nos processos e controles, além da interação dos agentes, por meio de comunicação e capacidades, permitindo a produção e a reprodução dessa área. Conclui-se que a dualidade da estrutura preconizada por Giddens (1979; 1996; 2003 ocorreu na empresa no período analisado, pois a estrutura impactou a interação e vice-versa.

Foram avaliados três tipos de estruturas. Em uma das estruturas as partículas foram distribuídas em camadas indistintas. Uma segunda estrutura foi constituída de 50% de partículas de eucalipto no miolo do colchão e 25% de pinus em cada face. A terceira estrutura foi formada por 50% de madeira de pinus no miolo e 25% de eucalipto nas faces. Cada uma dessas estruturas foi aglutinada com 4, 6 ou 8% de sólidos resinosos em relação ao peso seco das partículas de um adesivo fenólico com viscosidade de 350 cps, pH 12,15 e 47,63% de sólidos. Para os nove tratamentos foram feitas três repetições, totalizando 27 chapas. As chapas foram submetidas aos testes de flexão estática, ligação interna, arranque de parafuso, inchamento em espessura e absorção de água, obedecendo aos critérios da norma ASTM D 1037 - 91. De modo geral os painéis feitos com 8% de adesivo apresentaram melhores resultados que os demais. Para a maioria das propriedades mecânicas, inclusive para os painéis fabricados com 4% de resina, obtiveram-se resultados superiores àqueles estabelecidos pela Norma CSA O437-93. Contudo, nenhum tratamento produziu chapas com inchamento em espessura inferior ao valor máximo permitido por aquela norma. Não se verificou diferença estatística, ocasionada pela estrutura de colchão, entre todas as propriedades avaliadas.

Full Text Available The concern in milk quality, milk production, and in animals’ welfare is in constant increase. Mastitis is recognized as the main disease affecting dairy animals because of changing in milk composition and reduction in milk production. In Brazil, the highest incidence of mastitis is related to infectious agents. This study aimed to investigate the incidence of pathogenic microorganisms in milk produced by 60 cows from four dairy farms (15 cows/farm located at Sao Paulo state, Brazil. Milk samples from each teat were collected fortnight in sterile tubes, previously identified, during two months. In each herd 240 samples were obtained, except on the farm A, where an extra collection was done, in a total amount of 300 samples. On the farm A, the sampling was done in a period of transition between the dry and rainy season. On the farm B, samples were collected mostly in the season of high temperatures. On the farm C the collections were made over a period of heat and humidity. On the farm D, on a period of warmer temperatures and reduced rainfall. The isolation and identification of microorganisms were conducted at Laboratory of Milk Quality from Instituto de Zootecnia, Nova Odessa, São Paulo, Brazil. Aliquots of 100 mL of milk were grown on plates with 5% sheep blood agar. After incubation, they were used for the production of catalase and Gram stain. Gram positive and catalase positive samples were classified as Corynebacterium spp. (Coryne.. Gram positive cocci and catalase negative samples were classified as Streptococcus spp. (Strepto.. Milk were then proceeded to coagulase test in rabbit plasma. Gram-positive cocci, catalase positive and coagulase-negative were classified as Staphylococcus coagulase-negative (SCN. Gram positive, catalase positive and coagulase positive samples were subsequently subjected to biochemical tests: mannitol salt agar, maltose, trehalose, and acetoin production.

The Agencia Nacional de Petroleo - ANP - created in 1997 by the petroleum law has the role of regulating oil and natural gas industry activities in Brazil inciting the power self-sufficiency. The petroleum law states the end of petroleum exploration monopoly in Brazil performed by PETROBRAS. Between 1998 and 2004 ANP carried out six bid rounds in brazilian sedimentary basins offered to national and foreign companies. The exploratory activities in Bahia are resulting in commercial discoveries and positive impact to local economy. The petrochemical industry expects the startup of Manati field operation to supply repressed demand of natural gas as fuel and raw material. This article analyzes the legal and institutional processes and economics performances of these activities in Bahia's state. (author)

Brazil has one of the largest and fastest growing economies and one of the largest coastlines in the world, making human use and enjoyment of coastal and marine resources of fundamental importance to the country. Integrated assessments of ocean health are needed to understand the condition of a range of benefits that humans derive from marine systems and to evaluate where attention should be focused to improve the health of these systems. Here we describe the first such assessment for Brazil at both national and state levels. We applied the Ocean Health Index framework, which evaluates ten public goals for healthy oceans. Despite refinements of input data and model formulations, the national score of 60 (out of 100) was highly congruent with the previous global assessment for Brazil of 62. Variability in scores among coastal states was most striking for goals related to mariculture, protected areas, tourism, and clean waters. Extractive goals, including Food Provision, received low scores relative to habitat-related goals, such as Biodiversity. This study demonstrates the applicability of the Ocean Health Index at a regional scale, and its usefulness in highlighting existing data and knowledge gaps and identifying key policy and management recommendations. To improve Brazil's ocean health, this study suggests that future actions should focus on: enhancing fisheries management, expanding marine protected areas, and monitoring coastal habitats.

Highlights: → Sediment core study in the total fraction. → Elementary composition of sediment for dredged sediment regulation. → Multivariate analysis for determination of basal level of sediment composition. → Importance of the determination of local reference values for sediment studies. - Abstract: Ten sediment core samples with lengths ranging from 35 to 100 cm were collected in the Baixada Santista region and analyzed to determine As, Br, Co, Cr, Cs, Fe, Rb, Sb, Ta, Th, U, Zn and rare earths (Sc, Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) level concentrations using instrumental neutron activation analysis (INAA). The studied region is located in the southeastern coast of Sao Paulo State and is comprised of a densely urbanized area, the largest industrial complex of the country, with a predominance of petrochemical and fertilizer plants. It is also home to Brazil's most important and busiest port. The conclusions found that the As, La, Sm, Ne, Ce, Eu, Hf, Ta, Th, and U elements have a high background level in the region and that Fe and Zn were the main indicators of anthropogenic contribution in the sediments.

The Uranium Province of Lagoa Real is situated in the south-central part of the state of Bahia and constitutes, at the present moment, one of the most promising uranium districts of Brazil. The first anomaly was recorded in 1977 and, since then intense exploration and evaluation has been carried out in the area, resulting in the characterization of six ore deposits until now. Simultaneously, NUCLEBRAS has performed tests to establish the beneficiation characteristics of the ore, and developed preliminary mining plans. The host rock for the ore mineralization is related to sodic metasomatism and controlled by lithology and structure. The ore exhibits granoblastic texture, fine to coarse grain size, and the principal uranium minerals are uraninite, and, in minor quantities, pitchblende and uranophane. The solubility is over 90% of the U 3 O 8 contained, with an average acid consumption of 35 Kg per ton of ore treated. This paper presents a brief description of the main ore deposits and touches on their general characterisitcs. As an example, the deposit 'Jazida Cachoeira' is dealt with in greater detail, since this deposit is considered in the present context to be the most important one in the province. (Author) [pt

An outbreak of coccidioidomycosis is described that involved three individuals and eight of their dogs, who had engaged in a successful hunt for nine-banded armadillos (Dasypus novemcinctus) in the environs of Oeiras, a community in Brazil's north eastern state of Piauí. Diagnosis was based on clinical, serological and cultural findings. Four of 24 soil samples collected in and around the burrow of an armadillo yielded cultures of Coccidioides immitis, thus establishing the endemicity of that mould in the state of Piauí. A literature review revealed that C. immitis, aside from that state, is endemic in three other Brazilian states--Bahia, Ceará and Maranhão. These four contiguous states have semi-arid regions where climatic conditions and their flora are similar to those that exist in C. immitis's endemic regions in North, Central and South America.

Full Text Available The occurrence of HTLV-I/II and HIV-1 coinfections have been shown to be frequent, probably in consequence of their similar modes of transmission. This paper presents the prevalence of coinfection of HTLV among HIV-1 infected and AIDS patients in Belém, State of Pará, Brazil. A group of 149 patients attending the AIDS Reference Unit of the State Department of Health was tested for the presence of antibodies to HTLV-I/II using an enzyme immunoassay and the positive reactions were confirmed with a Western blot that discriminates between HTLV-I and HTLV-II infections. Four patients (2.7% were positive to HTLV-I, seven (4.7% to HTLV-II and one (0.7% showed an indeterminate pattern of reaction. The present results show for the first time in Belém not only the occurrence of HTLV-II/HIV-1 coinfections but also a higher prevalence of HTLV-II in relation to HTLV-I. Furthermore, it also enlarges the geographical limits of the endemic area for HTLV-II in the Amazon region of Brazil.

Full Text Available ABSTRACT Acute hemorrhagic conjunctivitis (AHC infection is highly contagious and can lead to explosive epidemics. In early February 2011, the Center for Epidemiologic Surveillance of the State of São Paulo Health Secretariat (SES-SP in Brazil received reports of conjunctivitis outbreaks from rural areas of the state that subsequently spread statewide. This report describes that AHC epidemic and its etiologic agent. Data from the Ministry of Health Information System for Notifiable Diseases (SinanNet and the SES-SP epidemiologic surveillance system for conjunctivitis, developed to detect outbreaks, confirm the etiologic agent, and carry out control measures, were analyzed. Eye (conjunctival swab samples were taken from patients with clinical presentation of viral conjunctivitis to perform viral laboratory diagnosis. A total of 1 067 981 conjunctivitis cases were reported to the surveillance system for 2011; there was an increase in the number of cases in epidemiologic weeks 6–26 (summer season versus previous years. Most cases occurred in the metropolitan region of Greater São Paulo. Of 93 collected samples, 57 tested positive for coxsackievirus-A24 (CV-A24, based on virus isolation in tissue-culture cell lines, reverse transcription polymerase chain reaction (RT-PCR, and enterovirus sequencing of RT-PCR. The data analysis showed that the fast-spreading etiologic agent of the AHC epidemic that occurred in the summer of 2011 was CV-A24. The AHC epidemic was due to an enterovirus that occurred sporadically, spread rapidly and with great magnitude, and had substantial socioeconomic impact due to the high level of absenteeism at work and school.

Genetic similarity among Agistemus pallinii Matioli et al (Acari: Stigmaeidae) found in citrus orchards in Vicosa, Minas Gerais state, Brazil

Stigmaeidae are very important predators of mite and insect pests on several crops in Brazil. It is considered the second most important family of predatory mites in citrus orchards in Brazil. However, their identification, especially that of the members of the genus Agistemus, is rather difficult based only on morphology. Hence, this study describes the use of random amplified polymorphic DNA (RAPD-PCR) markers to determine the genetic similarity of an Agistemus pallinii Matioli et al population found in 2004 in a citrus orchard in Vicosa, Minas Gerais State, Brazil, preying on Panonychus citri (McGregor). Amplifications were performed with 12 random primers (OPAA8, OPAA19, OPAB1, OPAB5, OPAB18, OPAC9, OPAC17, OPAC19, OPAD10, OPAE9, OPAE12 and OPAE17), which generated 119 bands, with 53.8% polymorphism. The coefficients of genetic similarity among the individuals ranged from 0.68 to 0.99, indicating a high genetic similarity among them. The 3D projection analysis clustered the majority of individuals confirming their high similarity. Though individuals of A. pallinii are minute (± 360 μm long), the PCR-RAPD technique can still be used for their identification, complementing morphological analyses or for comparison of populations collected in different geographic regions. This is the fi rst molecular study carried out with stigmaeid mites. (author)

Full Text Available Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC, which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

Bolivia-Brazil gas line route detailed

This paper reports that state oil companies of Brazil and Bolivia have signed an agreement outlining the route for a 2,270 km pipeline system to deliver natural gas from Bolivian fields to Southeast Brazil. The two sides currently are negotiating details about construction costs as well as contract volumes and prices. Capacity is projected at 283-565 MMcfd. No official details are available, but Roberto Y. Hukai, a director of the Sao Paulo engineering company Jaako Poyry/Technoplan, estimates transportation cost of the Bolivian gas at 90 cents/MMBTU. That would be competitive with the price of gas delivered to the Sao Paulo gas utility Comgas, he the. Brazil's Petroleos Brasileiro SA estimates construction of the pipeline on the Brazilian side alone with cost $1.2-1.4 billion. Bolivia's Yacimientos Petroliferos Fiscales Bolivianos (YPFB) is negotiating with private domestic and foreign investors for construction of the Bolivian portion of the project

Full Text Available Este artigo discute a estrutura epistêmica do mundo moderno em relação aos quatro genocídios/epistemicídios do longo século XVI (1450-1650. Argumenta-se que o privilégio epistêmico do homem ocidental foi construído às custas do genocídio/epistemicídios dos sujeitos coloniais. O artigo relaciona o racismo/sexismo epistêmico da estrutura das universidades ocidentalizadas e do mundo moderno ao genocídio/epistemicídio contra muçulmanos e judeus na conquista de Al-Andalus, contra povos nativos na conquista das Américas, contra povos africanos na conquista da África e a escravização dos mesmos nas Américas e, finalmente, contra as mulheres europeias queimadas vivas acusadas de bruxaria. Esses quatro genocídios/epistemicídios são fundantes da estrutura epistêmica moderno-colonial e das universidades ocidentalizadas. A tese principal deste artigo é que a condição de possibilidade para o cartesianismo idolátrico dos anos 1640 que assume o olho de Deus e arroga-se o direito de dizer "penso, logo existo" é o "extermino, logo existo".

Full Text Available In Brazil, the treatment of hepatitis C virus (HCV infection is funded by the national public health system (SUS. To evaluate treatment results in the state of Mato Grosso, central Brazil, we have consulted the files of the office of the State Department of Health responsible for supplying such medications. We obtained information on 232 treatments of 201 patients who underwent treatment in or prior to 2008. The study was conducted by reviewing medical records, making telephone calls and interviewing the assistant physicians. Thirty-nine patients (19.4% had cirrhosis and HCV genotype 1 predominated (64.3%. Excluding patients with comorbidities or treatment without ribavirin we analysed 175 treatments (sustained virologic response occurred in 32.6% of cases. Twenty-six of these 175 were retreatments and the sustained virological response (SVR rate among them was 30.8%; the SVR rate was 32.9% among those receiving treatment for the first time. The SVR rate of genotype 1 patients was 27.8%, whereas it was 37.5% in non-1 genotype patients. The adjusted multivariate analysis showed association of SVR with the absence of cirrhosis [odds ratio (OR: 7.7; confidence interval (CI 95%: 2.5, 33.3], the use of pegylated interferon (OR: 5.8; CI 95%: 1.5, 21.4, non-1 genotype (OR: 5.3; CI 95%: 1.7, 16.7 and uninterrupted treatment (OR: 9.0; CI 95%: 3.3, 45.4. The SVR rates were similar to those found in other Brazilian studies about HCV, but lower than those found in national and international clinical trials. These data suggest that the treatments of chronic hepatitis C that are made available by SUS does not, under normal conditions, work as well as the original controlled studies indicated.

Full Text Available The objective of this paper is to estimate the indirect tax burden on food for ten income classes, based on income and household total expenditure in southern Brazil. Thus it can be seen as indirect taxes on foods affect the monetary income and consumption pattern of households. To reach the objectives proposed, will be used the Pintos-Payeras (2008 model. The database iscomposed by microdata from the Household Budgeting Survey (POF 2008-2009 and the tax regulations of the country and the southern states of Brazil. The results show that indirect taxes on food in Southern Brazil is regressive when based on income and expenditure of household , ie , the poorest people pay proportionately more taxes and have their consumption pattern highest taxed ICMS (Brazilian value added tax is the tax that contributes most to the regressivity.
