  3. Elemental and radionuclides distribution in the production and use of phosphate fertilizers in Brazil; Distribuicao elementar e de radionuclideos na producao e uso de fertilizantes fosfatados no Brasil

    Saueia, Catia Heloisa Rosignoli


    Fertilizer is considered an essential component for agriculture, because its use increases the natural soil nutrients, which are lost slow waste or erosion. The Brazilian phosphate fertilizer is obtained by wet reaction of igneous phosphate rock with concentrated sulphuric acid, giving as final product, phosphoric acid and dihydrated calcium sulphate (phosphogypsum) as by-product. Phosphoric acid is the starting material for triple superphosphate (TSP), single superphosphate (SSP), monoammonium phosphate (MAP) and diammonium phosphate (DAP). The phosphate rock used as raw material presents in its composition, radionuclides of the U and Th natural series in. During the chemical attack of the phosphate rock, this equilibrium is disrupted and the radionuclides and the elements migrate to intermediate, final products and byproducts, according to their solubility and chemical properties. While the fertilizers are commercialized, the phosphogypsum is disposed in stack piles and can cause an impact in the environment. In order to evaluate the radionuclides and the elements distribution in the industrial process of phosphate fertilizer production, samples of concentrated rock, fertilizers (SSP, TSP, MAP and DAP) and phosphogypsum from three national industries (A, B and C), were analyzed. The characterization of the elements Ba, Co, Cr, Fe, Hf, Na, Sc, Ta, Th, U, Zn and Zr, and the rare earths La, Ce, Nd, Sm, Eu, Tb, Yb and Lu, were performed by instrumental neutron activation analysis. The results obtained showed that, in general, the rare earth elements are distributed uniformly in the fertilizers and phosphogypsum, except for Lu. The elemental concentration present in the fertilizers SSP and TSP are of the same order of magnitude of the source rock. The same behavior was observed in the fertilizers MAP and DAP, except for the elements Co, Sc and U. The radionuclides of the U series ({sup 238}U, {sup 234}U, {sup 230}Th, {sup 226}Ra, {sup 210}Pb) and of the Th series ({sup 232}Th, {sup 228}Ra, {sup 228}Th) and {sup 40}K were determined by gamma and alpha spectrometry. The fertilizers samples, with are derived directly from phosphoric acid, MAP and DAP, presented in their composition low activity concentrations for {sup 226}Ra, {sup 228}Ra and {sup 210}Pb. For U and Th, the concentrations founded in MAP and DAP are more significant, similar to the source rock. SSP and TSP fertilizers, which are obtained by mixing phosphoric acid with different amounts of phosphate rock, presented higher concentrations of all radionuclides of the natural series. Long-term exposure due to successive fertilizer and phosphogypsum application was evaluated. Internal doses due to the application of phosphate fertilizer and phosphogypsum for 10, 50 and 100 years were below 2.4 mSv y{sup -1}, showing that the radiological impact of such practice is negligible.

    Correa, Silvia R. [PETROBRAS, Rio de Janeiro, RJ (Brazil); Quintella, Odair M.; Farias Filho, Jose R. de [Universidade Federal Fluminense, Niteroi, RJ (Brazil)


    Great are the challenges established by the Brazilian Government related to goals to be achieved for the increment of the Natural Gas participation in brazilian energetic matrix, from current 5% to 12%, up to 2010. The enlargement of the distribution infrastructure of the gas (gas-pipelines 'mesh') in Brazil is considered one of the greatest challenges for the growth of the Brazilian market of Natural Gas, accomplishment that involves elevated investments. This paper presents a model of Management System for the good organizational performance of the small Natural Gas Supplying Brazilian Companies focused on criteria of Leadership, Strategies and Plans and Results, established by the Premio TOP Empresarial and by the 'Rumo a Excelencia', held by the 'Progama Qualidade Rio' and 'Fundacao para o Premio Nacional da Qualidade', respectively. The management practices of these companies were reviewed, considering the context of the energetic Brazilian scenario, subjected to the political and operational definitions and uncertainties, the available financial resources, limited or not prioritized, and actual barriers to be surpassed by the Gas Supplying Companies in order to achieve the pre-established government goals for this segment. The implementation of the proposed simplified Model, seen as improvement opportunities for the segment of Natural Gas distribution, will lead the Gas Distribution Companies to a intermediary stage envisioning the real steps towards the excellence of the performance.

    In Brazil, there are around 250 companies operating in the automotive fuel distribution segment, responsible for the automotive fuels wholesale commercialization activity. Those companies supply not only gas stations, but also final consumers and TRR's. Their clients are distributed regionally, which requires flexibility and the ability to supply clients efficiently at the smaller possible cost, transforming variables such as the transportation alternatives adopted, the location of the storage facilities and its correct dimension on key decisions. This paper analyses the general scenario of the fuels distribution logistics in Brazil from a economic perspective, and its impacts on the companies competitive strategies. (author)

  6. Natural gas conversion program of Rio de Janeiro-Brazil; Projeto de conversao do sistema de distribuicao de gas canalizado na cidade do Rio de Janeiro

    Pallottino, J.T.; Costa Filho, M.A.F.; Guarana, L.F.M.L. [Universidade do Estado do Rio de Janeiro (UERJ), RJ (Brazil); Margalef, J.M. [Companhia Estadual de Gas (CEG), Rio de Janeiro, RJ (Brazil)


    This paper presents the Conversion Project of Rio de Janeiro, Brazil, that converted all customers and the distribution network from Manufactured Gas (MG) to Natural Gas (NG), evaluating its logistic and benefits, highlighting those related to consumer safety. The Conversion Project was executed under the responsibility of CEG with the support of UERJ, specially on the definition and revision of the technical procedures as well as the quality assurance of the project execution. As main advantages followed by MG to NG network conversion, we can note: increasing of gas distribution network capacity and gas network operational condition improvements; elimination of production plant; revision and renovation of gas network; revision and repairing of building gas facilities; augmenting of NG usage; elimination of carbon monoxide as a supplied gas constituent. Conservation condition of most consumer internal gas facilities and ambient ventilation were so critical that conversion program resulted in no measurable accident prevention. The achieved safety level should be maintained through a periodically re-evaluation program of customer's gas facilities and appliances, with special focus on permanent ventilation required for NG safety usage.

Dept. de Energia Nuclear; Galindo, Izabel Cristina Luna, E-mail: [Universidade Federal Rural de Pernambuco (UFRPE), Recife, PE (Brazil). Dept. de Agronomia


    Contents of {sup 137}Cs have been used to quantify soil loss or accumulations, based on values of reference sites with little soil disturbance in the last decades. In Northeastern Brazil no such sites have been evaluated yet. Three areas with flat topography, native vegetation and undisturbed soil were selected in of Goiania, Araripina and Sertania counties, state of Pernambuco. Four points in each area were marked at a distance of 20 to 50 m away from each other and soil samples were collected in 3 cm depth intervals, down to 30 cm. The {sup 137}Cs activities were determined using gamma spectrometry with a hyper pure germanium detector. Average contents of {sup 137}Cs (Bq m{sup -2}) were 71.6 +- 6.3 in Goiania, 64.0 +- 13.8 in Araripina and 95.5 +- 9.8 in Sertania. Values in this range have been reported in Paraiba and Bahia, and higher ones in the Southeastern region, confirming the reduction of stocks in areas closer to the equator. The highest activities occurred in the surface layers, ranging from 0.5 to 1.6 Bq kg{sup -1}, and decreased linearly with depth until the detection limits: 18 cm in Araripina, 15 cm in Goiania, and 9 cm in Sertania. In Goiania, the activity was highest (2.06 +- 1.0 Bq kg{sup -1}) in an organic horizon above a inorganic horizon. The high activities and stock and lower depth in Sertania could be explained by the predominance of 2:1 clay minerals versus 1:1 clay minerals in the other areas. {sup 137}Cs activities were positively correlated with water and KCl pH values and negatively correlated with Al concentrations. The results confirm that, in the reference areas, {sup 137}Cs activities are highest in the surface layers, decreasing regularly down the soil profile. (author)

  12. Analyzing natural gas distribution in Brazil through EVA (Economic Value Added); Analise economico-financeira da industria de distribuicao de gas natural brasileiro sob a otica da geracao de valor

    Marques, Fernando Rodrigues; Parente, Virginia [Universidade de Sao Paulo (USP), SP (Brazil). Inst. de Eletrotecnica e Energia


    Although the Brazilian gas market has been showing steady growth and positive news regarding new discoveries, it is not immune to be questioned about its capacity of value generation, and, in particular, if the new companies, operating in distribution have generated it. Value creation, and its management, has become one of the main activities of the modern corporation in order to align the management and shareholders interests. Despite its advancements, the Brazilian NG industry can be considered at its early stages when compared to those of other countries whose industry is more traditional and mature. The process of unbundling of the gas industry, as well as of the public utilities, has become one of the icons of the Brazilian government policies since the mid 90's. Taking into account regulatory change which had only allowed in the last couple of decades the participation of private ownership into the domestic gas market, a follow up of these companies' performances is of interest. Following the concept of value generation, the present study examines the Brazilian gas distribution sector. Based on a detailed analysis of the financial statements of some of the main companies in the sector, that together represent around 68% of the total Brazilian market, this paper verifies whether the gas distribution sector have presented a positive or negative EVA{sup R}, in other words, if, during the period from 2002 to 2007, these newly companies in the gas industry have created or destroyed value in Brazil.

The evolution of the exploratory effort in Brazil in relation to its distribution in sedimentary basins and changes in the institutional structure: 1922 to 2008; A evolucao do esforco exploratorio no Brasil em relacao a sua distribuicao nas bacias sedimentares e as mudancas na estrutura institucional: 1922 a 2008

    Accioly, Felipe; Draghi, Julia [Agencia Nacional do Petroleo, Gas Natural e Biocombustiveis (ANP), Rio de Janeiro, RJ (Brazil)


    This study is based on the available data on the georeferred database of the Brazilian oil and gas government regulatory agency (ANP - Agencia Nacional do Petroleo Gas e Biocombustiveis) regarding the position, year of drilling and results of the oil and gas wells drilled in Brazil. The position of the wells were plotted on their sedimentary basins and grouped into five periods (1922-1953, 1954-1961, 1962 - 1970, 1971-1997, after 1997). For each period some of the most significant changes in the technical or institutional background were compiled and reported. Those maps allowed an interesting discussion on the criteria and methodology used to establish the prospect locations at each period and presented a possible explanation for the very low productivity of drilling in Brazil up to the 80's as much as the changes in the conceptual basis that lead to the successful performance of the 90's and the first decade of the 21st century (author)

This research aims to identify and determine the main variables that have an impact on the worker's dose. The results are presented for the Occupationally Exposed Individual variable, variable operation, variable area/Cell, task and Feature variable and variable duration of operation, depending on the Dose variable. It is intended in this way to contribute to improvements in operations in restricted areas that may result in lower individual doses without causing significant changes in the routine of work.

  18. Study of the distribution characteristics of rare earth elements in Solanum lycocarpum from different tropical environments in Brazil by neutron activation analysis; Estudo das caracteristicas de distribuicao de elementos terras raras em Solanum lycocarpum em diferentes ambientes tropicais do Brasil por ativacao neutronica

    Maria, Sheila Piorino


    In this work, the concentration of eight rare earth elements (REE), La, Ce, Nd, Sm, Eu, Tb, Yb and Lu, was determined by neutron activation analysis (INAA), in plant leaves of Solanum lycocarpum. This species is a typical Brazilian 'cerrado' plant, widely distributed in Brazil. The analysis of the plant reference materials CRM Pine Needles (NIST 1575) and Spruce Needles (BCR 101) proved that the methodology applied was sufficiently accurate and precise for the determination of REE in plants. In order to better evaluate the uptake of the REE from the soil to the plant, the host soil was also analyzed by ESiAA. The studied areas were Salitre, MG, Serra do Cipo, MG, Lagoa da Pampulha and Mangabeiras, in Belo Horizonte, MG, and Cerrado de Emas, in Pirassununga, SP. The results were analyzed through the calculation of transfer factors soil-plant and by using diagrams normalized to chondrites. The data obtained showed different transfer factors from soil to plant as the subtract changes. Similar distribution patterns for the soil and the plant were obtained in all the studied sites, presenting an enrichment of the light REE (La to Sm), in contrast to the heavy REE (Eu to Lu), less absorbed. These results indicate that the light REE remain available to the plant in the more superficial soil layers. The similarity between the distribution patterns indicates a typical REE absorption by this species, in spite of the significant differences in the substratum . (author)

A adubação com N e K e os tratamentos com P e S° foram realizados manualmente no sulco de plantio, sendo posteriormente semeadas com o híbrido Agroceres 8021. O SFT proporcionou maior rendimento de grãos, em comparação com o FNR, no primeiro ano de cultivo. A eficiência agronômica do FNR foi de 43% e 33% na presença e ausência de S, respectivamente. O teor de fósforo no tecido foliar foi inferior com o uso do FNR. A dose de 30 kg ha-1 de S elementar não interferiu no pH do solo, mas aumentou a eficiência da adubação fosfatada.

  20. Brazil

    Technological advances by newly industrialized countries (NICs) have become a central concern of the recent literature on the political economy of development. Striking a fatal blow to dependency thinking, in so far as it had diagnosed a structural barrier to technological development, these countries have absorbed foreign technology and have developed a very impressive domestic technological capacity. Moreover, their exports have evolved from a traditional reliance on raw materials and unprocessed goods to include increasingly sophisticated manufactured goods and technology itself. The capabilities, motivations, and structures behind nuclear exports must be examined in light of these secular trends. This paper reports on this exploratory analysis of the country's emergence as a nuclear supplier which focuses on six major areas: the balance of motivations and constraints underlying Brazil's nuclear export potential; areas of extant capabilities that would allow the country to play a significant role as a nuclear supplier; formal and informal structures beneath nuclear export policy; patterns of nuclear trade as reflected in past transactions; prospects for continuity and change; generalizability of findings to other emerging suppliers

    Full Text Available O artigo aborda a geometria para crianças, seu ensino para alunos das primeiras séries escolares. Leva em conta, inicialmente, a trajetória da Geometria para o nível elementar, desde, praticamente, a Independência do Brasil. Nessa análise, evidencia a permanência de conteúdos da geometria euclidiana até quase meados do século XX. Em seguida, analisa as propostas de alteração do ensino de Geometria elaboradas na década de 1960. Com isso, procura mostrar as intenções de modificar os conteúdos desse ramo matemático, em busca da redefinição de um novo elementar: um novo conhecimento elementar de geometria, vindo de processos de apropriação das contribuições trazidas pelos estudos da Psicologia cognitiva.The article discusses geometry for children and its teaching for students from early grades. It takes into account, firstly, the geometry journey at the elementary level since practically the Independence of Brazil. This analysis highlights the presence of Euclidean geometry contents up to the mid-twentieth century. It then analyzes the proposed amendment to the teaching of geometry developed in the 1960s. Thus, this article attempts to show the intentions to modify the contents of this branch of mathematics in search of a redefinition of the 'new elementary': a new elementary knowledge of geometry, coming from the appropriation processes of the contributions made by studies of cognitive psychology.

  2. The Elementary Forms of Risk: The Mobility Immobilized / As Formas Elementares de Risco: A Mobilidade Imobilizada

    Maximiliano E Korstanje


    Full Text Available Modernity and mobilities have been widely studied from many perspectives. Any movement opens new limens and boundaries that denote the status of travelers. In our days, neither the lineage nor the kinship determines the identity of subject. We often accept the belief that we live in a modern mobile world, which unlike ancient world, presents new opportunities to more free knowledge and social relations. But mobility engenders risks, and risk has been a buzz-word topic examined by sociology for more than 30 years. In contrast to current state of the art, that claims risks are negative elements that affect the advertising of tourist destinations, we argue that the risk is not only enrooted in capitalism, but also in the act of traveling. The concept of risk and mobilities are inextricably linked in the capitalist ethos. As Formas Elementares do Risco: A Mobilidade Imobilizada - Modernidade e mobilidade tem sido amplamente estudadas por diferentes vieses acadêmicosnos, nos últimos 30 anos. Muito embora seja amplamente aceito que estejamos vivendo em um mundo móvel, se em comparação com outras civilizações, pouco se considera-se que qualquer movimento ou deslocamento desafia a identidade  e a pertença do sujeito ao território. A mobilidade, por sua vez, também gera riscos, levando a que o mesmo seja uma categoria de análise importante; em contraste com o que tem sido escrito, que postula risco como um aspecto negativo na propaganda de destinos turísticos, defende-se neste ensaio o risco como parte inerente da viagem e da mobilidade.

    Full Text Available O objetivo deste trabalho foi avaliar a assimilação de enxofre elementar (S0, aplicado nas folhas de soja, e sua eficiência comparada à adubação feita ao solo, de acordo com a dose e a natureza da fonte do nutriente. O S0 aplicado às folhas, independentemente da dose e fonte, foi assimilado pela planta, o que acarretou em aumento no teor de proteína total na folha. Todas as fontes de S aplicadas às folhas aumentaram a produção de grãos, semelhantemente à aplicação ao solo. Observou-se uma mesma produtividade com o uso de 20 kg ha-1 de S0 no solo ou de 6 kg ha-1 via foliar. A eficiência da aplicação de S via foliar, com base no conteúdo de proteína solúvel total, foi superior à da aplicação ao solo.The objective of this work was to evaluate the elementary sulfur (S0 assimilation applied on soybean leaves, and its efficiency compared to the fertilization done in the soil, according to the dose and nature of the nutrient source. The S0 applied to leaves, independently of the dose and source, was assimilated by the plant, what resulted in increase of total protein content in the leaf. All S sources applied to leaves increased the grain yield, similarly to the application to the soil. The same productivity was observed with the use of 20 kg ha-1 of S0 in the soil or 6 kg ha-1 applied to leaves. The elementary S application efficiency on leaves, based on the content of total soluble protein, was superior to application efficiency on soil.

    Leite, Fabio Augusto C.C.M.; Costa, Hirdan Katarina de M. [Universidade Federal do Rio Grande do Norte (UFRN), Natal, RN (Brazil). Faculdade de Direito


    In these past few years, natural gas in Brazil has arised as one of the alternatives for the energetic crisis suffered by the country. Such situation was one of the motives for its expansion, rising, after that, the importance of the regulation of its distribution. The regulation of canalized natural gas distribution can be found in the Federal Constitution, after Constitutional Amendment n. 05/95, in the article n. 25, para. 2nd, which say that belongs to the Federal States the concession or direct exercise of canalized natural gas services, now clearly classified as a public service. In order of these events, its imperative the analysis of natural gas distribution's public service, because it belongs to the Federal States. According to this situation, the study of the new regulatory function of the Administration and the tracing of action for the regulatory state agencies are the main goals of this work. As so, the present research aims to focus the reflexes from the actual dimension of natural gas distribution, specially referring to its regulatory statements, the limitations of state agencies, the National Petroleum Agency and the market where distribution belongs, and particularly the open access of new agents.

    Guimaraes, Regina C.L.; Gomes, Alexandre de O. [PETROBRAS S.A., Rio de Janeiro, RJ (Brazil)


    Naphthenic acid corrosion was observed for the first time during the distillation process of some kind of crude oils in 1920. Recent reports about naphthenic acid corrosion have been found in China, India, Venezuela, Eastern Europe, Russia and the USA. In Brazil, heavy and acid crude oil processing is rising. Some brazilian crude oils have TAN around 3,0 mg KOH/g. The presence of relatively high levels of naphthenic acids in crude oils is a bane of petroleum refiners; and more recently, of producers as well, who have reported problems during production with calcium and sodium naphthenate . Essentially, these acids which are found to greater or lesser extent in virtually all crude oils are corrosive and tend to cause equipment failures, lead to high maintenance costs and may pose environmental disposal problems. In order to give these information to PETROBRAS, The Research and Development Center of PETROBRAS (CENPES) has been working in house and with brazilian universities developing analytical technicians to know better molecular structures and distribution of these acids compounds in crude oils. This work presents the actual methods and some results from these developments. (author)

  8. Calculation of the energy efficiency of fuel processor – PEM (proton exchange membrane) fuel cell systems from fuel elementar composition and heating value

    This simulative work analyzes the impact of fuel type on the energy efficiency of systems composed by a fuel processor for hydrogen production and a PEM (proton exchange membrane) fuel cell. Two fuel processors are simulated, one employs steam reforming to produce hydrogen, the other one autothermal reforming. In both cases, fuel processing is completed by two water gas shift units and one preferential CO oxidation unit. Five classes of fuels are considered, i.e. alkanes, alkenes and alkynes, alcohols and aromatics and steam to carbon and oxygen to carbon inlet ratios, reforming temperature, fuel cell split fraction and exhaust gas temperature are explored as operative parameters. For each fuel considered, Aspen Plus® was used to calculate the operative conditions that maximize the energy efficiency of the systems. For each system, the data were employed to identify an analytic expression to calculate the best possible energy efficiency given the elementar composition of the fuel and its lower heating value. The expressions proved to hold true for a broad range of fuel types. - Highlights: • Simulation of fuel processor – PEM fuel cell systems. • Optimization of operating conditions for different fuels. • Scaling of energy efficiency data. • Analytic expression to calculate energy efficiency for different fuels

  9. Saberes escolares matemáticos en los primeros años escolares: ¿la matemática superior de un ponto de vista elementar?

    Wagner Rodrigues Valente


    Full Text Available El texto tiene por objetivo problematizar la matemática de los primeros años escolares en una perspectiva histórica. Apoyado en recientes resultados de investigación oriundos de proyectos realizados en cooperación nacional e internacional, este trabajo analiza las dificultades de realización de estudios históricos sobre la presencia de la matemática en la formación inicial de los alumnos. Entre estas dificultades, se destaca el modo de tratar las enseñanzas matemáticas sobre la forma de asignaturas y no contenidos disciplinarizados. Esto implica especial atención para la articulación que ocurre entre pedagogías y saberes a ser enseñados. Y, en este caso, se impone el análisis de las finalidades culturales, en cada tiempo escolar, del papel del conocimiento matemático. Entre los resultados del estudio, se evidencia un punto de inflexión con la urgencia de las pedagogías modernas en las últimas décadas del siglo XIX y primeras del siglo XX, y la redefinición de lo elementar en matemática.

    Human teeth were analysed by {mu}SRXRF. The measurements were carried out in small areas of the teeth from enamel to root. The aim of this work was to evaluated the local elemental variations in the dental regions, enamel, dentine and pulp from patterns of relative intensities. The distributions of the elements Ca, Zn and Sr were studied. The samples (canine, premolars and molar teeth) were cross-sectioned along the vertical median plane, by polishing the whole tooth in order to obtain a smooth and plane surface, of about 1 mm thick. The measurements were carried out in the XRF beamline of the Synchrotron Light National Laboratory, Campinas, Brazil using a conventional collimation system (orthogonal slits 300 {mu}m x 300 {mu}m). The Ca concentration is quite constant and it is independent of the tooth type and individual characteristics. Ca and Sr distributions show a similar behavior. An increase of the Zn concentration was found for the pulp region and for untreated carious areas. (author)

  13. The obstacles for the investments in natural gas distribution infrastructure in Brazil; Os obstaculos aos investimentos na rede de distribuicao de gas natural no Brasil

    Almeida, Edmar Luiz Fagundes de; Bueno, Salua Saud; Selles, Vitor [Universidade Federal do Rio de Janeiro (UFRJ), RJ (Brazil). Inst. de Economia


    This paper analyses the main obstacles for the expansion of the Brazilian gas distribution pipelines infrastructure. The paper examines the evolution of investments in the gas chain and highlights the existence of an important unbalance between the level of investments in the upstream and transportation segments and the level of investment in the distribution network. It is clear that the level of investments in the distribution segment is not following the pace of expansion of the other segments. Given this conclusion, the paper examines the potential for increasing the level of investment in the distribution segment by augmenting the debt level of distribution companies. By analyzing the main distribution companies' financial statements, the paper shows that they there is room for an expansion in investments through financial leverage. Finally, the paper examines the main financing obstacles that impede the companies to increase their investment level. (author)

  14. Distribution of natural gas: introduction of the interruptible segment in Sao Paulo, Brazil; Distribuicao de gas natural canalizado: introducao do segmento interruptivel em Sao Paulo

    Paula, Claudio Paiva de [Agencia Reguladora de Saneamento e Energia do Estado de Sao Paulo (ARSESP), SP (Brazil)


    The principal objective of this paper is the better knowledge and evaluation of the natural gas distribution network interruptible branch. This new service can be appropriate for thermal power generation on flexible dispatch mode, as 'take or pay' contracts surplus jobs. The paper indicates no regulatory restraints in an interruptible network implantation and one can guess that the inexistence of contracts for this service resembles only lack of conjunctural opportunities for this job applications. These difficulties appear both in the supply and distribution branches of the gas business, which prefer flat contracts. The final conclusion is interruptible contracts can be an improvement on the distribution business and certainly can accommodate a suitable demand and supply volumes in the long-term gas market balance.

  15. As formas elementares da vida religiosa e as ciências sociais contemporâneas The elementary forms of the religious life and the contemporary social sciences

    Renato Ortiz


    Full Text Available A partir da questão "como abordar a problemática das ciências sociais contemporâneas tendo como referência a obra específica de um autor?", o artigo examina As formas elementares da vida religiosa de Émile Durkheim. Recusa a alternativa de recuperar sua influência junto a uma série de intelectuais relevantes na área e segue outra direção - a saber, a de indagar o que o leitor contemporâneo pode retirar desse texto - na qual privilegia um olhar retrospectivo imerso no presente, pois, em relação ao momento da escritura daquela obra, a compreensão do funcionamento das sociedades humanas avançou. Mostra que a discussão sobre o sagrado não se confina à temática da religião, ao lembrar que, na conclusão do livro sob exame, Durkheim faz uma série de digressões acerca da problemática do simbólico. Esses símbolos, indispensáveis à criação e recriação das sociedades, são retomados no desenvolvimento deste texto.Beginning from the question "how to address the problems of the contemporary social sciences taking a specific work of an author as reference?", this article examines The elementary forms of religious life by Émile Durkheim. It refuses the alternative of regain his influence on relevant intellectuals in the area, and goes in another direction - namely, to inquire what the contemporary reader can obtain from that work - in which a retrospective look, immersed in the present, is privileged, because, in relation to the time in which this book was written, progressed the comprehension of how work the human societies. It shows that the discussion about the sacred is not confined to the topic of religion, to remember that, at the conclusion of the book under review, Durkheim makes a series of digressions about the problematic of symbolic. These symbols, which are necessary for the social creation and recreation, are incorporated on the development of this article.

  16. Optimization combinatorial for expansion of gas distribution networks; Otimizacao combinatoria para expansao de redes de distribuicao de gas

    Costa, Wagner Emanoel; Gouvea, Elizabeth Ferreira; Goldbarg, Marco Cesar [Rio Grande do Norte Univ., Natal, RN (Brazil). Dept. de Informatica e Matematica Aplicada]. E-mail:;;


    Brazil is in a excellent context for the development of natural gas as energy source. The responsibility of design a network to deliver gas increases with the new investments made every day. However the computer aided design (CAD) technologies for gas network design were poor developed because in EUA and Europe have their gas networks from long time ago, in such that only a little of the potential of computer had been explored for the gas network design. This work studies the use of combinatorial optimization techniques and others techniques from evolutionary computing to find layouts to create and expand a network and make the pipeline optimization looking for costs minimizations and respecting all demands of pressures and flow.

  17. Logistical management system for natural gas distribution; Sistema de gestao logistica para a distribuicao de gas natural

    Arruda, Joao Bosco F.; Nobre Junior, Ernesto F.; Praca, Eduardo R. [Universidade Federal do Ceara (UFC), Fortaleza, CE (Brazil). Nucleo de Pesquisa em Logistica, Transportes e Desenvolvimento


    The Brazilian Federal Government has the very purpose of increasing the participation of the Natural Gas in the primary energy internal supply from 7,5% nowadays to about 12% till 2010. However, for that, it is necessary to eliminate the great impedance represented by the restricted accessibility to the product, due to the high distribution costs involved. So, there is an urgent need for availability of technologies to help natural gas distribution systems. This paper proposes an innovative logistics-based approach on the subject of the natural gas distribution, through a computational tool (GASLOG System) to be applied in the North and Northeastern urban and country areas of Brazil, with initial case study in the city of Fortaleza. In its conception, the GASLOG System focuses on the point-of-view of everyone of the actors involved with the natural gas distribution process trying to respond their particular necessities in the sector.

  18. Meccanica statistica elementare i fondamenti

    Falcioni, Massimo


    La meccanica statistica (MS) nell'insegnamente universitario e' spesso confinata in una posizione itermedia tra le tre grandi aree della fisica teorica, la fisica della materia e la fisica matematica. In genere vengono discussi gli aspetti "pratici", di supporto alla fisica della materia, che pur importanti non esauriscono la rilevanza concettule della meccanica statistica. Esistono molti ottimi libri (Huang, Landau-Lifsits, Chandler, Peliti etc) che trattano in modo dettagliato gli aspetti tecnici della meccanica statistica. Lo scopo del nostro libro non e' quello di presentare metodi (esatti ed approssimati) per determinare le proprietà termodinamiche a partire dalle interazioni microscopiche, quanto discutere alcuni aspetti concettuali della meccanica statistica che sono spesso poco trattati. In particolare: 1- Il ruolo dell'ipotesi ergodica 2- L'importanza dei tanti gradi di libertà per le leggi statistiche 3- L'interpretazione degli ensemble in termini di probabilità; 4- L'irreversibilità macroscopic...

  5. Datafile: Brazil

    There is as yet little to show for the enormous investment made by Brazil over the past 20 years in nuclear power and the fuel cycle. The only nuclear power plant (657MWe PWR) in operation has had a poor performance record and the two reactors (1309MWe PWRs) under construction are more than ten years behind the original schedule. Aspirations of building commercial fuel cycle facilities have proved extremely optimistic. In the latest reorganization of the industry, the construction and operation of nuclear power stations is entrusted to the national utility and the various civilian/military R and D efforts in the fuel cycle are being integrated under civilian supervision. This should lead to greater accountability and efficiency in the future. (author)

    Soares, Rogerio M.F.; Limoeiro, Claudio D.P. [PETROBRAS, Rio de Janeiro, RJ (Brazil); Zerbini, Jose E.; Blanco, Jose F. [PETROBRAS Distribuidora, Rio de Janeiro, RJ (Brazil)


    The deregulation of the oil product distribution segment in Brazil is inducing higher competition and causing reduction of profit margins for all players in the industry. Until the beginning of the 90's, each of the most important products had the same price all over the country, with freight cost differences being integrally paid by the Brazilian Government. In the context of higher competition the minimization of distribution costs turns to be very important for the survival of players in the marketing and distribution sector. In order to achieve this goal, PETROBRAS Distribuidora (BR) has been using, since 1999, a decision support system known as LogDis that incorporates optimization algorithms and geographic information system, helping the supply planners to work in a better and more effective basis. This paper intends to describe and present this system. (author)

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

  19. Uranium deposits of Brazil

    Brazil is a country of vast natural resources, including numerous uranium deposits. In support of the country's nuclear power program, Brazil has developed the most active uranium industry in South America. Brazil has one operating reactor (Angra 1, a 626-MWe PWR), and two under construction. The country's economic challenges have slowed the progress of its nuclear program. At present, the Pocos de Caldas district is the only active uranium production. In 1990, the Cercado open-pit mine produced approximately 45 metric tons (MT) U3O8 (100 thousand pounds). Brazil's state-owned uranium production and processing company, Uranio do Brasil, announced it has decided to begin shifting its production from the high-cost and nearly depleted deposits at Pocos de Caldas, to lower-cost reserves at Lagoa Real. Production at Lagoa Real is schedules to begin by 1993. In addition to these two districts, Brazil has many other known uranium deposits, and as a whole, it is estimated that Brazil has over 275,000 MT U3O8 (600 million pounds U3O8) in reserves

    Over 1700 liver transplantations (LTs) are performed annually in Brazil. In absolute terms, the country performs more LT surgeries than anywhere else in Latin America and is third worldwide. However, due to its increasing population and inadequate donor organ supply, the country averages 5-10 LTs per million population, far lower than required. There is a marked heterogeneity in organ donation and LT activity throughout the country. Access to LT in the underprivileged North, Midwest, and Northeast regions of Brazil is scarce. Major challenges for the future of LT in Brazil will be to increase organ donation and access to LT. The reduction of those geographical disparities in donation, organ procurement, and LT due to political and financial constraints is of utmost importance.

  3. Eand P opportunities in Brazil

    Castilho, Marcelo [National Petroleum Agency of Brasil (Brazil)


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

  4. Brazil: anchoring the region

    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

  5. Chikungunya risk for Brazil

    Raimunda do Socorro da Silva Azevedo


    Full Text Available This study aimed to show, based on the literature on the subject, the potential for dispersal and establishment of the chikungunya virus in Brazil. The chikungunya virus, a Togaviridae member of the genusAlphavirus, reached the Americas in 2013 and, the following year, more than a million cases were reported. In Brazil, indigenous transmission was registered in Amapa and Bahia States, even during the period of low rainfall, exposing the whole country to the risk of virus spreading. Brazil is historically infested by Ae. aegypti and Ae. albopictus, also dengue vectors. Chikungunya may spread, and it is important to take measures to prevent the virus from becoming endemic in the country. Adequate care for patients with chikungunya fever requires training general practitioners, rheumatologists, nurses, and experts in laboratory diagnosis. Up to November 2014, more than 1,000 cases of the virus were reported in Brazil. There is a need for experimental studies in animal models to understand the dynamics of infection and the pathogenesis as well as to identify pathophysiological mechanisms that may contribute to identifying effective drugs against the virus. Clinical trials are needed to identify the causal relationship between the virus and serious injuries observed in different organs and joints. In the absence of vaccines or effective drugs against the virus, currently the only way to prevent the disease is vector control, which will also reduce the number of cases of dengue fever.

  6. Regulation of the natural gas distribution sector: a comparison of Brazilian and Colombian industries; Regulacao do setor de distribuicao de gas natural: uma comparacao dos casos brasileiro e colombiano

    Domingues, Mariana Peralva; Ferraro, Marcelo Colomer [Universidade Federal do Rio de Janeiro (UFRJ), RJ (Brazil)


    The Bolivia oil industry nationalization in 2006 and the high price of oil on the international market called the public and government attention to the problems of the natural gas industry regulation in Brazil. Recently, the establishment of a specific law for the natural gas industry had been debated in academic circles and in government institutions. In Brazil, the absence of an integrated energy policy and the absence of a homogeneous regulatory framework interfere with natural gas industry development, especially in distribution. Thus, the objective of the work will be contrast the Colombia distribution natural gas regulatory structure sector to the Brazilian natural gas regulatory framework. The comparison of the Brazilian regulatory framework and the Colombian natural gas regulation shows that the existence of different kinds of concession contracts in distribution is one of the explanations for the different levels of investment in Brazil. The contract with exclusive right to explore the distribution service in geographic territories also contributes to explain the low coverage rate of public distribution companies. Thus, the rapid expansion of the natural gas distribution network in Colombia after the regulatory reforms shows the importance of the establishment of a regulatory structure to push private investment. The Colombian case can be considered a good model for other countries in South America, especially to the natural gas distribution regulation. (author)

    Pfahl, Andreas; Bezerra, Pedro; Hölle, Erwin; Liedke, Phillip; Teramoto, Erico Tadao; Hertel, Johannes; Lampkowski, Marcelo; Oliveira, L.


    For Brazil it is important to realize a high local production share because of high import tax rates. The rim drive concept offers an alternative for expensive heliostat drive solutions with slew and linear drives from abroad. By (locally produced) rims the demands on the drives regarding strength and precision are reduced to a very low value and low cost drives can be used. Sandwich facets (which are usually foreseen for rim drive heliostats) are not available from Brazilian manufacturers an...

  11. Radiopharmacy education in Brazil

    Ralph Santos-Oliveira


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

Those curves allow to obtain the diversity curves. The second application focused the calculation of the distribution transformer life reduction.

  13. Relation between aerosol particles and their optical properties: a case study for São Paulo-Brazil

    Miranda, Regina; Andrade, Maria de Fatima


    Brazil has a territory of 8.5 million km2 and a population of more than 160 million inhabitants, distributed throughout 26 states. Brazillian capital-cities with millions inhabitants and vehicles have several problems concerning air pollution. São Paulo, capital of São Paulo State, with more than 19 million inhabitants, 7 million vehicles, as well as the major industrial and technological park of the country, has high concentrations of air pollutants, especially in the winter. Air pollution, high building density, and a lack of green areas, combined with the proliferation of asphalt and concrete surfaces, have resulted in a greater number of urban heat island effects, fewer drizzle events, and rainfall events of greater intensity. São Paulo has an extensive air quality monitoring network, which has shown that ozone levels often exceed the NAAQS limit during spring and summer, and that concentrations of inhalable particles exceed the NAAQS limit mainly during the winter, from June to August. Aerosols are produced by a variety of processes, creating differences in their physicochemical properties and hence in their ability to scatter and absorb solar radiation. For most urban areas in Brazil, vehicles are considered the principal source of particles emitted to the atmosphere. Particles have been monitored in the winter of 2012 in São Paulo using a MOUDI (Micro Orifice Uniform Deposit Impactor), in order to have the mass distribution of the aerosol. The concentrations of coarse particles can still be larger than those of fine particles, although the difference between both has become smaller than in the past. The samples collected were analyzed by gravimetry for mass concentration, optical reflectance for Black Carbon concentration and X-ray Fluorescence for elementar characterization. Optical properties were obtained from Aeronet (Aerosol Robotic Network, for São Paulo city. It was found that a high fraction of elements was derived

  14. Economic impacts of current harmonic from nonlinear loads on residential electricity distribution networks; Impactos economicos dos harmonicos de corrente das cargas nao lineares em redes eletricas de distribuicao residenciais

    Duarte, Carlos Henrique


    To achieve more efficient energy use, power electronics systems (PES) may be employed. However, this introduce nonlinear loads into the system by generating undesired frequencies that are harmonic in relation to (multiples of) the fundamental frequency (60 Hz in Brazil). Consequently, devices using PES (power electronics systems) are more efficient but also contribute significantly to degradation of power quality. Besides this, both the conventional rules on design and operation of power systems and the usual premises followed in energy efficiency programs (without mentioning the electricity consumed by the devices themselves) consider the sinusoidal voltage and current waveforms at the fixed fundamental frequency (60 Hz in Brazil) of the power grid. Thus, analysis of electricity consumption reductions in energy efficiency programs that include the use of PES considers the reduction of kWh to the final consumer but not the additional losses caused by the increase in harmonic distortion. This dissertation investigates this problem by exploring a case study of the ownership and use of television sets (TV sets) to estimate the economic impacts of residential PES on a mainly residential electricity distribution system.

  20. Social Psychotherapy in Brazil.

    Fleury, Heloisa J; Marra, Marlene M; Knobel, Anna M


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

  1. Fuelwood utilization in Brazil

    The annual consumption of fuelwood in Brazil is approximately equal to 180 million oil barrels, or 13.3% of all Brazilian primary energy use. Fuelwood consumption in the country is greater than the use of wood for industrial use. Fuelwood taken from existing forest has been a very common activity in Brazil. Forest plantations to support the Brazilian fuelwood consumption have not been important. As fuelwood consumption in the country is expected to increase in the future, it is important to increase the supply of wood by sustainable use of the existing natural forests. Even if they are far from the centers of consumption, these are only available reserves capable of supporting the Brazilian future fuelwood requirements. For this reason it is necessary to use advanced technology to convert the energy of wood efficiently into a form (such as electricity) to carry it to the centers of consumption. In addition, forest plantations would be established in the available areas, mainly for specific uses, as for charcoal production for the pig-iron and steel industries. In all the above plans, at least, the US3/2 billion/year that represents the current Brazilian fuelwood consumption should be returned to rehabilitate the forest growing stock. In addition, it would be used to stimulate the development and use of the most suitable systems of fuelwood conversion, improving the efficiency of energy production. (author)

  2. Waste management in Brazil

    The waste management policies set up in developed countries have in general been used by other countries with less experience in the nuclear field as the basis for developing waste disposal rules or guidelines according to their particular political, social and economic conditions. The waste management question became a main concern in Brazil during the licensing period of the Angra I nuclear power plant and the other fuel cycle facilities envisaged under the Agreement between Brazil and the Federal Republic of Germany. Before the Angra I licensing period, all final waste products arising from nuclear activities were released into the environment because their radioactive levels were below the standard limits. The Research, Development and Demonstration (RDD) Project initiated by the National Nuclear Energy Commission has the purpose to provide information that may contribute to the formulation of recommendations for a waste disposal policy, as well as to demonstrate the feasibility of the Brazilian waste disposal concept. The paper briefly describes the waste management policy in some countries, their contributions to the studies carried out in the RDD Project, and the recommendations and mechanisms for implementing the waste management proposal, and presents general information concerning the Brazilian repository concept.

  4. Space activities in Brazil

    Carvalho, H.; Kono, J.; Quintino, M.; Perondi, L.

    Brazilian space activities develop around three main programs, namely, the China-Brazil Earth Resources Satellite (CBERS) , the Applications Satellite program, comprising the Multi-Mission Platform and associated remote sensing payloads (radar and optical), and the Scientific Satellites program. Increasing national industry participation and acquiring new technology are strategic goals established for all programs. CBERS program is the result of successful long term cooperation between China and Brazil for the development of remote sensing satellites. Initially comprising two satellites, launched in 1999 and 2003, and now extended to four, this cooperation fulfills the needs of both countries in earth imagery. CBERS satellites are designed for global coverage and include cameras for high spatial resolution and wide field of view, in the visible, near infrared spectrum, an infrared multi-spectral scanner, and a Transponder for the Brazilian Environmental Data Collection System to gather data on the environment. They are unique systems due to the use of onboard cameras which combine features that are specially designed to resolve the broad range of space and time scales involved in our ecosystem. Applications satellites, mainly devoted to optical and radar remote sensing, are being developed in the frame of international cooperation agreements, and will be based on the use of a recurrent Multi-Mission Platform (MMP), currently under development. The MMP will be 3-axes stabilized and will have a fine pointing capability, in several pointing modes, such as Earth, Inertial or Sun pointing. Missions will be focused on natural resources observation and monitoring.. The Program for Scientific Satellites is based on low-cost micro-satellites and aims at providing frequent flight opportunities for scientific research from space, whilst serving as a technological development platform, involving Research Institutes, Universities and National Industry. Current projects are FBM

  5. Pediatric lymphomas in Brazil

    Gabriela Gualco


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

  6. Familial hypercholesterolemia in Brazil.

    Dos Santos, J E; Zago, M A


    The Brazilian population has heterogeneous ethnic origins and is unevenly distributed in a country of continental dimensions. In addition to the Portuguese colonists until the end of the World War II Brazil received almost 5 million immigrants who settled mainly in the south and southeast. This features of the Brazilian population have two important consequences for the inherited diseases that are associated with an ethnic background: their frequencies are different in various regions of the country reflecting a variety of ethnic origins and variable degrees of admixtures. There was no report about the molecular basis of hypercholesterolemia in Brazil until our report in 1996 that the Lebanese allele is the most common cause of the disease in our country: 10 out of the 30 families were of Arab origin, and the Lebanese allele was detected in 9 of the 10 unrelated families of Arab origin. In addition, the abnormal gene is associated with the same haplotype at the LDL-R locus in all but one family, suggesting single origin for this mutation. Recently we described seven mutations in exons 4, 7, 12 and 14 and a new mutation in exon 15. In another region of our state, eight mutation already described and seven new mutations were described and interesting no common mutations were find. We can conclude that the complex history and structure of the Brazilian population, which was formed by the contribution of a large number of ethnic components that are in a state of increasing miscegenation, is reflected in the frequency and regional distribution of the more common hereditary diseases.

    Perdiz, Lauro Daniel Beisl; Sousa, Eduardo F. de; Flor, Ricardo Antonio Maciel [Universidade Salvador (UNIFACS), BA (Brazil)], email:


    Brazil has gone through its worst crisis in electricity supply in the past fifty years. The justifications for the current crisis are found in the eighties, when there was a long period of underinvestment in the sector, until then controlled and managed exclusively by the state, especially in the expansion of generation and power transmission network. The lack of financial resources by the state led to the delay or suspension of expansion projects. Consumption, meanwhile, increased when the economy grew and continued to increase even when the economy stagnated, as more people gained access to electricity. It became imperative, then implode the model that barely functioned at that time under the command of the state and devise a new model for the electricity sector, which should have as main goals: to attract the participation of private investment coupled with gradual tariff reduction the State, in addition to increased competition among agents in the chain, to enable the pricing more affordable to society, and better quality services.

  9. Computational intelligence applied to the logistics of electric energy distribution network maintenance teams; Inteligencia computacional aplicada a logistica de equipes de manutencao de redes de distribuicao de energia eletrica

    Bobel, Edson [Companhia Paranaense de Energia (COPEL), Curitiba, PR (Brazil)]. E-mails:; Lopes, Heitor Silverio [Universidade Tecnologica Federal do Parana (UTFPR), Curitiba (Brazil)]. E-mail:


    One of the problems that an Electric Energy Distribution Company faces is the maintenance of its distribution network. This study focuses on the problem of allocating emergency maintenance teams so that costs related to the energy outage as well as the cost of the teams themselves are minimized. This study includes a geographic area of 108 counties in the State of Parana, Brazil, and uses information related to: interruptions history in high voltage switches, list of locations able to allocate emergency maintenance teams and list of switches that were actually served by the maintenance teams during the year 2002. With this information and the list of locations with emergency maintenance teams, an estimate of the situation is made and the costs are calculated for the year 2002. With this in hand, the problem was solved using two methods: p-medians and genetic algorithms, in which the potential gains of 13.37% and 12.64% were obtained, respectively, as compared to the costs in 2002, for the same geographic area. Finally, a projection was made for the potential decrease of costs for the Electric Distribution Company regarding the total area of Parana State, as well as an estimate of financial profits for the State Government.

Car emission control policies in Brazil have relied basically on mandatory emission standards and subsidies for specific cleaner technology resulting in substantial decrease of car emission rates. Nevertheless, car sale taxes, differentiated by vehicles’ size and fuel, h...

  12. Distribution of kerma rate in the air inside of hemodynamic room for typical projections of interventionist cardiology procedures; Distribuicao da taxa de kerma no ar em uma sala de hemodinamica para projecoes tipicas de procedimentos de cardiologia intervencionista

    Sanchez, Mirtha Elizabet Gamarra


    The evaluation of dose to physicians involved in Interventional Cardiology (IC) is an extreme important matter due to the high and non-uniform distribution of dose values. The radiation control during each procedure is complex and the reasons for the high exposures have many different causes. Many international recommendations have already been written aiming the radiation protection optimization in IC. In Brazil, there is not any special orientation for the protection of those occupational persons, nor a specific legislation. The purpose of this work is to evaluate the air kerma rate at critical anatomic regions of the occupationally exposed staff that carry out IC procedures, in representative incidences in order to give subsidies for individual monitoring procedures implementation and to give more information about their radiation protection. The air kerma rate has been measured in the often used condition in the two more common IC procedures namely angiography and coronary angioplasty, using an adult patient simulator irradiated under RAO, LAO and AP projections for fluoro and digital acquisition modes. The measurements have been made in 45 points around the examination table at 5 different representatives heights of: eyes lens, thorax, hands, gonads and knees. AP projection shows the smaller scattered radiation contributions and a more homogeneous exposure distribution. The digital acquisition mode gives air kerma rates about 4 times higher than fluoro mode for LAO projection in the position occupied by the interventionist doctor, the anesthetist and the nursing staff. The most critical anatomic regions are: knees and gonads (without protection). On the physician hands position, values as high as 5 mGy/h have been measured, which can overpass, depending on the number of procedures done, the individual occupational annual limit. Therefore, in IC it is necessary to implement additional protection tools, elaborate safety guides (based on international experiences

  13. Legal and regulatory possibility of connection between interstate natural gas distribution networks instead of constructing transport pipelines; Possibilidade juridoco-regulatoria da conexao interestadual entre redes de distribuicao de gas natural como alternativa a construcao de gasodutos de transporte

    Goncalves, Gustavo Mano [Andrade, Mano - Advogados, Rio de Janeiro, RJ (Brazil)


    According to Revista Brasil Energia (2011a), the local natural gas distribution concessionaire in the State of Sao Paulo Gas Brasiliano Distribuidora - GBD, plans to expand its distribution pipeline network in western Sao Paulo up to the border of the State of Minas Gerais, near the region known as Minas Triangle where a connection with the pipeline network of the State of Minas Gerais' natural gas distribution company, Companhia de Gas de Minas Gerais - GASMIG shall be built in order to supply natural gas to an ammonia plant to be built by PETROBRAS in the City of Uberaba. Still according to the publication, the project described above would be an alternative to the construction of a transportation pipeline that, since the enforcement of the Gas Law - Law No. 11.909/09 (Brasil, 2009), should be subject to concession contracts preceded by a complex, and probably delayed, planning and procurement. However, there is a transportation pipeline project, deriving from the Bolivia-Brazil transportation pipeline near the city of Sao Carlos, in Sao Paulo, crossing the Minas Triangle and finishing in the State of Goias. This project is owned by TGBC Company. The existence of two gas pipeline projects with very similar paths to supply virtually the same regions and based on different regulatory frameworks, one consisting of a connection between the distribution networks of different States and another based on the concept of pipeline transportation of gas under the legal and regulatory federal jurisdiction raises the discussion about the possibility of legal and regulatory interstate connections of distribution pipeline networks as an alternative to planning, allocation and construction of a transportation pipelines. This article aims to examine the legal and regulatory foundations of both alternatives and delineate the limits of performance of States and Federal Government on legislation and regulation concerning the movement of natural gas pipeline through the Country

  14. Assessing the safety aspects for use of multilayer pipes in gas distribution of domestic installation; Avaliacao dos aspectos de seguranca para utilizacao de tubos multicamada em instalacoes de distribuicao de gas em residencias

    Bratfisch, Carlos do Amaral Coutinho [Bratfisch - Engenharia em Gas, Sao Paulo, SP (Brazil); Emmeti, Sao Paulo, SP (Brazil); Collela, Ricardo [FGS Brasil Industria e Comercio Ltda., Cotia, SP (Brazil)


    The gas distribution networks average flow at the Brazilian market is low and the operating pressure is less than 2.0 kgf/cm{sup 2}. These values are lower if compared to other countries and due this, gas distribution companies, major builders and developers have started a movement to find alternatives to reduce their installation costs, and they have identified in other countries the multilayer system. Because of the great interest of the consumer market for this alternative, and since there is no standards in Brazil that could regulate it, a technical committee was established under the ABNT in order to prepare a standard draft meeting the local market particularities as well this technology requirements. Then it was initiated a quest looking for the knowledge of the 'state of the art' of this technology in various locations around the world, especially Europe, Asia and Oceania, which shows that, with few exceptions, the knowledge of this alternative is still on the beginning, and even in countries where this system is a pioneer some doubts exist with respect to their usage limit. The multilayer system materials were already used at hot and cold water networks for more than twelve years, but only after that it was made an adaptation for building installations of gas distribution networks. Due the need to search and establish safety criteria both with respect to the product as its installation shape, did the necessary motivation to perform a more detailed study of this new technology, meeting the needs of this market. The intention is to present to the consumer market a series of comparative data definitions and techniques to identify this as a modern, updated, economic, efficient and safe alternative option for gas distribution networks.

  15. Country watch. Brazil.

    Turra, M D


    Persons who are infected with human immunodeficiency virus (HIV) or who suffer from acquired immunodeficiency syndrome (AIDS) often have their civil rights violated in Brazil. To remedy this, the Candido Mendes College in Rio de Janeiro introduced a voluntary course, "AIDS - Legal Approaches", into its law curriculum. Incentive was provided by the college's Model Law Office (MLO), where students learn to defend the rights of people in need. Class size is about 25; law professors use recent magazine and newspaper articles, and documentation on lawsuits concerning persons with HIV to teach the class. Course topics include relevant civil law (suits against blood banks), contract law (suits against private health insurance companies which refuse to cover treatment expenses related to HIV or AIDS), family law, inheritance law, labor law (unjust dismissal of persons with HIV), criminal law (intentional transmission of AIDS), violations of basic human rights, and comparative jurisprudence and constitutional law (a comparison of Brazilian law in this area to the laws of other countries). Students, during their field practice periods at the MLO, provide legal assistance to persons with HIV. Approximately 150 cases have been handled, often with positive outcomes, to date. Clients hear about the program via television, radio, and newspapers. Materials and information about lawsuits handled by the MLO are available to other colleges and universities with the hope of stimulating the formation of similar programs elsewhere. PMID:12288109

  16. Ethanol fuels in Brazil

    The largest alternative transportation fuels program in the world today is Brazil's Proalcool Program. About 6.0 million metric tons of oil equivalent (MTOE) of ethanol, derived mainly from sugar cane, were consumed as transportation fuels in 1991 (equivalent to 127,000 barrels of crude oil per day). Total primary energy consumed by the Brazilian economy in 1991 was 184.1 million MTOE, and approximately 4.3 million vehicles -- about one third of the total vehicle fleet or about 40 percent of the total car population -- run on hydrous or open-quotes neatclose quotes ethanol at the azeotropic composition (96 percent ethanol, 4 percent water, by volume). Additional transportation fuels available in the country are diesel and gasoline, the latter of which is defined by three grades. Gasoline A (regular, leaded gas)d has virtually been replaced by gasoline C, a blend of gasoline and up to 22 percent anhydrous ethanol by volume, and gasoline B (premium gasoline) has been discontinued as a result of neat ethanol market penetration

  17. Argentina and Brazil

    This paper reports that security is defined in different ways by many international actors. To some, security is tied to the definition of an external threat to borders, as in the case of the NATO countries. To other, security is related to development, as in the case of most Third World countries. but notwithstanding different definitions, all countries recognize that the essence of security is the survival of the nation-state itself. The nuclear programs of Argentina and Brazil are among the oldest, most sophisticated and advanced nuclear programs anywhere in the Third World. The programs have never been explained on the basis of threat perception, and in this regard perhaps they constitute the most atypical form of nuclear proliferation known to date. Not surprisingly, any attempt to explain the rationale for the Brazilian and Argentine nuclear programs based on common issues of threat =merely confuses the issue. Thus, nationalism, the search for national identity and pride, the need to express self-sufficiency and the desire to keep options open in an insecure and evolving world order must all be analyzed to comprehend the likelihood of future types of nuclear proliferation. Meanwhile, the study of the contemporary era of Argentine-Brazilian nuclear rapprochement may provide new insights into the complex reasoning behind the decision of countries to go nuclear

  18. Policing violence in Brazil.

    Sena, E


    This article is an excerpted summary of a speech on female police and domestic violence. The speech was given by a woman affiliated with the Association of Women Workers at an Oxfam workshop in northern Brazil. This organization successfully lobbied for female police, which resulted in more reports of domestic violence, especially rape. The organization is active in 13 counties. Female police are trained and usually given respect by police chiefs. In one city, in 1997, the appointment of female police resulted in registered reports of 387 cases of violence and hospital reports of 503 cases, of which 14% were child rape. During January-April 1998, there were 126 registered cases and 168 hospital cases. Policewomen formed a partnership over the past 2 years with the Human Rights Group and other popular political groups to train female police about laws. The compulsory course focused on four areas: legal concepts, penalties, and procedures on registration of complaints; the Brazilian Penal Code; civil law; and world judicial bureaucracies. Training includes a 1 month internship with the program's lawyer. Over 20 women have completed the course to date. Training in some cases resulted in greater expertise among the female police than their Police Chiefs. Female police have experienced harassment by local authorities. PMID:12295035

  4. Zika virus outbreak in Brazil.

    Heukelbach, Jorg; Alencar, Carlos Henrique; Kelvin, Alyson Ann; de Oliveira, Wanderson Kleber; Pamplona de Góes Cavalcanti, Luciano


    Zika virus (ZIKV) infection is spreading rapidly within the Americas after originating from an outbreak in Brazil. We describe the current ZIKV infection epidemic in Brazil and the neurological symptoms arising. First cases of an acute exanthematic disease were reported in Brazil's Northeast region at the end of 2014. In March 2015, autochthonous ZIKV was determined to be the causative agent of the exanthematic disease. As cases of neurological syndromes in regions where ZIKV, dengue and/or Chikungunya viruses co-circulate were reported, ZIKV was also identified in the cerebrospinal fluid of patients with acute neurological syndromes and previous exanthematic disease. By the end of September 2015, an increasing number of infants with small head circumference or microcephaly were noted in Brazil's Northeast which was estimated to be 29 cases between August and October. ZIKV was identified in blood and tissue samples of a newborn and in mothers who had given birth to infants with microcephaly and ophthalmological anomalies. In 2015, there were an estimated 440,000 - 1,300,000 Zika cases in Brazil. There have been 4,783 suspected cases of microcephaly, most of them in the Northeast of Brazil associated with 76 deaths. The Ministry of Health is intensifying control measures against the mosquito Aedes aegypti and implemented intensive surveillance actions. Further studies are needed to confirm the suspected association between ZIKV infection and microcephaly; to identify antiviral, immunotherapy, or prophylactic vaccine; to introduce diagnostic ELISA testing. Clinical and epidemiological studies must be performed to describe viral dynamics and expansion of the outbreak. PMID:26927450

  5. Sexuality education in Brazil.

    Suplicy, M


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

  6. Mutation breeding in Brazil

    How mutation induction is used for plant breeding in Brazil is reported. For upland rice, the combined treatment with gamma-ray and mutagens (ethylene imine or ethylmethane sulfonate) has been used on the variety, Dourado Precoce, and some mutants with shortculm length and/or earliness without altering the productivity have been obtained. A project on the quantitative and qualitative protein improvement in upland rice was also started in 1979. In corn, the effect of gamma-irradiation on heterosis has been analyzed, and it was found that the single hybrids from two parental lines derived from irradiated seeds had increased ear productivity. For beans (Phaseolus yulgaris), gamma-irradiation and chemical mutagens have been used to induce the mutants with different seed color, disease resistance to golden mosaic virus and Xanthomonas phaseoli, earliness, high productivity and high protein content. Some mutants with partly improved characters have been obtained in these experiments. Two varieties of wheat tolerant to aluminum toxicity have been obtained, but the one showed high lodging due to its unfavorable plant height, and the other was highly susceptible to culm rust. Therefore, irradiation experiments have been started to improve these characters. The projects involving the use of gamma-irradiation have been tested to obtain the mutant lines insensitive to photoperiod and resistant to bud-blight in soybean, the mutant lines resistant to mosaic virus in papaya, the photoperiod-insensitive mutants in sorghum, the mosaic virus resistant and non-flowering mutants in sugar cane, and the Fusarium and nematode-resistant mutants in black pepper.

  7. Country watch: Brazil.

    Szterenfeld, C


    The Health in Prostitution Project was launched in 1991 in Rio de Janeiro, Brazil. The project offers a multi-year training program of health education designed to both fight the stigmatization of and violence against commercial sex workers and enhance their self-esteem, self-determination, and access to civil rights. The project therefore promotes individual awareness while influencing public opinion and policies. At first, health agents were recruited among women and transvestites who work in street-based sex work. The program was then gradually expanded to include young male sex workers and other locations, such as private parlors, saunas, and escort services. People of all sexes and sexual orientation now comprise the health agent group. The program has a paid staff of five women, three young men, and three transvestites, and approximately 70 sex workers are trained annually. Basic training includes topics such as human sexuality, personal risk assessment, HIV/STD infection, negotiation of safer sex, and STD referral services. Year two training emphasizes reproductive and women's health issues, while year three courses prioritize street work methodologies. Theatrical performances, speaking English as a second language, and performing Bach flower therapy for clients take place during the fourth year. Program trainers include medical specialists, nurses, psychologists, health educators, lawyers, and university students. At least half of the 350 health agents trained thus far are estimated to be currently engaged in paid or voluntary prevention work. Two surveys with female sex workers in 1991 and 1993 found that reported regular condom use increased from 57% to 73%; the health agents are having an effect. The program is constantly evaluated and revised. PMID:12346918

  8. Consumers' healthcare rights in Brazil.

    Schmidt, M J


    In many countries the rights of patients and consumers of health services are gaining ground and becoming law. As elsewhere, consumers in Brazil are becoming increasingly knowledgeable and demanding respect for their rights. Yet many Brazilian health services--public and private--are still reluctant to accept public evaluation and criticism. But with Brazil's new consumer's code the stage is set for a more active role of patients in their health decisions and for nurses and health professionals to acquiesce to consumers' dissatisfaction and respond with improved professional performance.

  13. The population question in Brazil.


    Population control programs were instituted in Brazil in the 1960s and resulted in as 50% reduction of the fertility rate in 20 years with a reduction in population growth from 2.9%/year in the 1960s to 2.1% in the 1980s. The rapid urbanization which has occurred in Brazil also contributed to this process. While the Brazilian government has eschewed foreign intervention, it encourages the population control programs which are funded by international agencies. The women's movement became involved in policies relating to reproductive rights in 1980, and attempts were made to change the focus of women's health care and the right of women to make reproductive choices. 71% of Brazilian women of reproductive age who are married or living in consensual union use contraception. This compares with 70% of women in developed countries. In Brazil, however, 44% of the women have been sterilized, 41% use oral contraceptives (OCs), and 12% use natural or barrier methods, compared to 7, 13, and 41%, respectively, in developed countries. Sterilization is illegal in Brazil, although it is widespread; the high number of Cesarean section births may determine a medical need for sterilization (after three such deliveries, for example). Abortion is also illegal (except in cases of rape or if the mother's life is in danger) and widespread. The 2 to 3 million abortions each year are thought to be the third cause of maternal mortality. Studies of OC use have shown that Brazilian women often use OCs without medical monitoring or in cases when the contraceptive is absolutely contraindicated. In the past few years, Brazilian women's groups have demanded that the government deal with the issue of family planning in order to stop the intervention of international population control agencies. Brazil has never had the sufficiently modern and effective policy to help women to use contraception safely during the various stages of their reproductive lives. PMID:12286343

  14. Electric power universalization: a political analysis of the energy distribution and its socio-environmental importance for the Amazon state, Brazil; Universalizacao da energia eletrica: uma analise politica da distribuicao de energia e da sua importancia socio-ambiental para o Amazonas

    The global distribution of electric energy in this article, attend to the electric and social exclusion and to regional inequalities in developing countries, with the objective to put up arguments about the question of the social and environmental injustice. It considers the need to plan the balance between the nature budget and the society budget without forgetting the fundamental principles of the thermodynamic and powerful interests involved. Alert to dangers of the exploit the natural resources looking for more energy. Although, the article shows up, the importance of the energy in developing societies. It gives information from IBGE and MME, about the relation between electric exclusion and social exclusion, calling attention to the impossibility to see concrete solutions, out of the social-economic context. Difficulties to construct Amazon indicators were improved on partly by own estimate, because the importance of the Amazon region to the environmental sustainability and the demographic, social and economic difficulties to the electric energy distribution for all Brazilian people.

  15. Aerial gamma spectrometry of the uranium province of Lagoa Real (Caetite, BA, Brazil): go environmental aspects and distribution of the absorbed dose in the air; Espectrometria gama aerea da provincia uranifera de Lagoa Real (Caetite, BA): aspectos geoambientais e distribuicao da dose absorvida no ar

    Santos, Esau Francisco Sena


    In the present study, it was analyzed the surface concentrations of the natural radioelements K, U and Th, as well as the absorbed dose rate in air caused by gamma radiation from the Lagoa Real uranium province, which is located at the center southern portion of Bahia State and comprises an area of approximately 4.600 Km{sup 2}. Data from the airborne gamma ray spectrometric survey of the region (Sao Timoeo Project) carried out in 1979, was used in this study. Besides, recent data of U, Th and absorbed dose rates from the Environmental Monitoring Program of the uranium concentration plant (URA), operated in the region by the Brazilian Nuclear Industries (INB), were used with the aim of inter compare the sampling points in the same geo referenced area. Imaging geo processing software's give support to frame maps of surface concentrations and ternary maps, as well as allow the integration of these with other themes (e.g. hydrology, geology, pedology) favouring the interpretation of geo environmental process from the radioactive cartography. Considering the whole study area, it was obtained the following mean values: absorbed dose rate in air (61,08 nGy.h{sup -1}), Potassium (1,65 % K) , Uranium (3,02 ppm eU) and thorium (18,26 ppm eTh). The geological unities bounding the uranium anomalies were placed in the areas characterized by the highest values of radioelements and, as expected, the major dose levels. The use of ternary maps coupled with the geology and hydrology allowed distinguishing the relationship between the surface distribution of natural radioelements and the geo environmental aspects, including the influence of the catchment in their transport and migration.

    Luiz C.R. Pessenda


    Full Text Available The aim of this research was to reconstruct vegetation changes (with climate inferences that occurred during the Holocene in the Fernando de Noronha Island, Pernambuco State, northeastern Brazil. The research approach included the use of geochemical (mineralogy, elemental, carbon isotopes (δ13C, 14C and pollen analyses in soil organic matter (SOM and sediments collected in Lagoa da Viração and Manguezal do Sueste. The carbon isotopes data of SOM indicated that there was no significant vegetation changes during the last 7400 BP, suggesting that the climate was not the determinant factor for the vegetation dynamics. The pollen analysis of the sediment of a core collected in the Lagoa da Viração showed the absence of Quaternary material in the period between 720 BP and 90 BP. The mineralogical analysis of deeper layer showed the presence of diopside indicating this material was developed "in situ". Only in the shallow part of the core were found pollen of similar plant species of the modern vegetation. The geochemistry and isotope results, in association with the sediment type and pollen analyses of sediment samples of Manguezal do Sueste, indicated variations in the vegetation and in its location since the middle Holocene. Such variations can be associated with climatic events and sea level oscillations and also with anthropogenic events considering the last five hundred years.Esta pesquisa teve o objetivo de reconstruir trocas de vegetação (com referências climáticas que ocorreram durante o Holoceno na ilha de Fernando de Noronha, Estado de Pernambuco, nordeste do Brasil.

  6. State Government Bailouts in Brazil

    Bevilaqua, Afonso S.


    As a result of the consolidation of democracy after the end of the military regime in the mid-1980s, Brazil has gone through a period of remarkable decentralization both in fiscal and political terms. The move towards decentralized management and control of public finances has been followed by a series of bailouts of state governments by the federal government. The lack of effective control on borrowing, coupled with reputational effects originating from these repeated bailout operations, red...

  9. Brazil-Africa geological links

    Torquato, Joaquim Raul; Cordani, Umberto G.


    In this work, the main evidence and conclusions regarding geological links between Brazil and Africa are summarized, with emphasis on the geochronological aspects. Taking into account the geographical position, as well as the similarities in the geochronological pattern, the following main provinces of the two continents are correlated: The Imataca and Falawatra complexes in the Guayana Shield and the Liberian Province of West Africa. The Paraguay-Araguaia and the Rockelide Fold Belts. The Sa˜o Luiz and the West African cratonic areas. The Caririan Fold Belt of northeastern Brazil and the Pan-Africa Belt of Nigeria and Cameroon. The JequiéComplex of Bahia, the Ntem Complex of Cameroon and similar rocks of Gabon and Angola. The Ribeira Fold Belt in Brazil and the West Congo and Damara Belts in West and South Africa. In addition, other geological links are considered, such as some of the major linear fault zones which can be traced across the margins of South America and Africa, in the pre-drift reconstructions. Correlations are also made of the tectonic and stratigraphic evolution of the Paranáand Karroo syneclises, and the Brazilian and African marginal basins around the South Atlantic, during their initial stages. Finally, several similarities in the tectonic evolution of South America and Africa, during and after the onset of drifting, are shown to be compatible with a recent origin for the South Atlantic floor, as required by sea-floor spreading and continental drift between South America and Africa.

  10. Decentralization and REDD+ in Brazil

    Fabiano Toni


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

  11. An AIDS campaign in Brazil.

    Janoff, D


    The Acquired Immune Deficiency Syndrome (AIDS) distribution program in Brazil, spearheaded by the National Division of Sanitary Surveillance in Ports, Airports, and Borders, was part of the government's massive education campaign to prevent the transmission of HIV-AIDS in Brazil. Beginning in February 1987, the climate was sufficiently favorable to operate a coordinated information campaign during the Carnival celebration, and tourists arriving in the cities of Brazil for the annual Carnival celebration were handed an educational brochure in Portugese, Spanish, English, and French. Yet, beyond reaching the tourist populations, it is particularly important to reach large portions of the Brazilian population. Planners of the national AIDS campaign intend to use television, radio, and all major newspapers in their effort to cover the country. Initial television coverage is comprised of short informational messages directed at high-risk groups. There also are plans to use radio and the print media in order to reach a wider audience. It is estimated that US $6 million will be needed to adequately meet the costs of AIDS prevention and medical care, but due to extreme budget constraints, only $45,000 has been earmarked for ongoing AIDS activities at this time.

  13. History of nuclear power in Brazil

    Rosa, L.P.


    The 1973 energy crisis prompted the United States to suspend supplies of enriched uranium to the reactor being built in Brazil, Angra I. In 1975, the Brazil-Germany Nuclear Agreement was announced. The Programme was a failure. Today the Angra II nuclear reactor has been completed, the only reactor completed under the agreement with Germany. Brazil's last military President implemented the Parallel Nuclear Programme, which included uranium enrichment with the justification of developing the technology that had not been transferred through the Nuclear Agreement with Germany. In 1986, the existence of a deep shaft drilled by the Air Force was revealed. A Technical Report concluded that it had all the characteristics and dimensions required to test a nuclear bomb. Some years later, the Civilian Government acknowledged the existence of an underground nuclear explosion facility and symbolically sealed this shaft. The situation in Brazil has improved recently. Brazil ratified the Treaty of Tlatelolco on the denuclearisation of Latin America and established ABACC, an agency handling mutual inspections of nuclear facilities in Brazil and Argentina. Brazil also signed the Nuclear Weapons Non-Proliferation Treaty. The uranium enrichment activities are being transferred to a civilian industry. More importantly, I do not believe that the uranium enrichment project is intended to endow Brazil with the capacity to produce nuclear weapons. (author)

  17. An overview on small hydro in Brazil

    An overview of small-scale hydro development in Brazil was presented in the context of the Brazilian energy sector. Brazil's energy sector is currently comprised of 45 per cent renewable energy. Brazil is the tenth largest energy producer in the world, with an installed capacity of 105.986 MW. Brazil currently has an estimated 258.410 MW of hydroelectric power potential. Small hydropower (SHP) plants in Brazil are defined as plants capable of producing up to 30 MW of power, with a reservoir area smaller than 12 km2. It is estimated that SHP plants will provide 5 per cent of Brazil's electrical supply by 2030. SHP plants in Brazil typically use Kaplan and Pelton hydraulic turbines, as well as Michell-Banki cross-flow turbines. Hydrokinetic turbine prototypes are also being designed at the Federal University of Brazil. Researchers are currently developing a diffuser enhancement design. However, there are currently no designs available that use peripheric generators. Researchers are currently investigating the design of fish-friendly turbines as well as mobile dams. Development projects in the Amazon region were outlined. tabs., figs.

  19. The ethanol program in Brazil

    Goldemberg, José


    The number of automobiles in the world has been growing fast and today requires one quarter of the global petroleum consumption. This problem requires adequate solutions, one of which Brazil has achieved with the Sugarcane Ethanol Program. This paper presents the history of this program, from its launch in the 1970s to the today's condition of full competitiveness in a free market. It also shows how it can be replicated to other countries, in order to replace 10 per cent of the world's gasoline consumption.

  20. Geodiversity and geoconservation in Brazil

    Cardozo Moreira, Jasmine; Muggler, Cristine Carole


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

  1. Brazil: World Oil Report 1991

    This paper reports that Brazil's state oil company Petrobras has racked up a significant period of achievement over the last 12 months. Average daily oil production hit a new high. A small portion of deepwater giant Marlim field came onstream. Risk contracts ended, and the firm assumed all responsibility for exploration activity in Brazil. Furthermore, Santos basin proved to be the nation's most recent oil province after two discoveries. Last, but not least, Petrobras assumed a dominant position worldwide in development of new deepwater technology, as evidenced by papers presented at the 1991 Offshore Technology Conference. What is remarkable is that all this was achieved while the company was experiencing political turmoil. Last Oct. 19, Petrobras President Luis Octavio Motta Veiga resigned in a dispute with the Ministry of Economy (MOE) over refined product pricing levels. His replacement, interestingly enough, was the 36-year-old executive secretary of the MOE, Eduardo de Freitas Teixeira. His term at Petrobras lasted less than six months

  2. Nuclear research reactors in Brazil

    Cota, Anna Paula Leite; Mesquita, Amir Zacarias, E-mail: aplc@cdtn.b, E-mail: amir@cdtn.b [Centro de Desenvolvimento da Tecnologia Nuclear (CDTN/CNEN-MG), Belo Horizonte, MG (Brazil)


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

  3. Hereditary haemoglobin disorders in Brazil.

    Zago, M A; Costa, F F


    The data on the incidence and variability of hereditary haemoglobin (Hb) disorders in Brazil are reviewed. The most common abnormalities are HbS, HbC and beta-thalassaemias. Both homozygotes and compound heterozygotes for these genes (i.e., HbS/HbC disease, S/beta-thalassaemia, C/beta-thalassaemia) are common, owing to the free miscegenation of populations of Mediterranean and African ancestry. The diversity of beta-thalassaemias is similar to that observed in other regions. beta(0)-Thalassaemia is more frequent than the beta(+) variant among affected individuals. Most patients are descendants of Italian immigrants but occasional cases have other racial origins. Patients with thalassaemia major are mostly beta (0) homozygotes, while thalassaemia intermedia is more heterogeneous, including a variety of genotypes. alpha-Thalassaemias are not common although cases of HbH disease have been reported. Isolated examples of several Hb variants have been described, and two abnormal Hb were first found in Brazil: Hb Porto Alegre and Hb Niteroi. PMID:3898485

  4. Homosexuality and adoption in Brazil.

    Uziel, A P


    Western societies are undergoing legal and policy changes in relation to laws governing the family, marital status, sexual orientation and the welfare of children, including in Brazil where, in the 1990s, the rights of homosexuals were incorporated into ongoing debates about what constitutes a family. This paper discusses the issue of adoption of children by homosexual men in Brazil, using information from court records from 1995-2000 in Rio de Janeiro, and from interviews with two judges, five psychologists and four social workers who evaluate those wishing to adopt. It uses the case records of one man's application to adopt, in which homosexuality became a central issue. Both the construction of masculinity in relation to parenting and concepts of the family were the parameters upon which the decision to allow him to adopt or not depended. Because the legislation does not specify what the sexual orientation of would-be adoptive parents should be, it is possible for single persons to adopt if they show they can be good parents. As more single people, alone or in couples, seek to adopt, it is important to clarify the criteria for judicial decisions on adoption applications. A dialogue is therefore needed on the meaning of family and whether and how it relates to sexual orientation. It is only on this basis that the courts can take a clear decision as to whether being homosexual is a relevant issue in regard to applications to adopt or not. PMID:11765396

  8. Brazil in the global energy world

    Kim, Frank D.; Vossoughi, Shapour [University of Kansas (KU), KS (United States)


    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 This study evaluates the nature of the Brazilian public comprehension of international news by revealing the quality of such reception with regard to a sample of 170 subjects randomly selected in the city of Porto Alegre, Brazil. A questionnaire was created taking as a basis the directives of Bloom et al(1972. Evaluated in it are the cognitive and aff ective dimensions of thought. In the fi rst case, questions were formulated that allowed the establishment of the level of knowledge of individuals, as well as their comprehension abilities, application, analysis, synthesis, and evaluation of a wide range of international news topics. For the aff ective dimension the following abilities were evaluated: attention, response, valorization, organization and the structuring of a value scale.

  18. The role of nuclear energy in Brazil

    Electricity consumption in Brazil continues to grow at a faster rate than electricity generation, and in 1991 consumption reached 227 TWh, surpassing generation by more than 22 TWh. Thus, for Brazil to achieve its ambitious economic development plan, in addition to solving its current political and macroeconomic issues, the development and diversification of alternative energy resources remains a high priority. As early as the 1970s, Brazil began to seriously consider nuclear energy as the main alternative source of energy that could help the country meet its projected electricity requirements through the end of the century. This decision was based primarily on the fact that Brazil's known reserves of uranium are far greater in energy content than that of its coal or oil reserves

  8. Epidemiological Scenario of Dengue in Brazil

    Fares, Rafaelle C. G.; Souza, Katia P. R.; Germán Añez; Maria Rios


    Dengue is the most important reemerging mosquito-borne viral disease worldwide. It is caused by any of four Dengue virus types or serotypes (DENV-1 to DENV-4) and is transmitted by mosquitoes from the genus Aedes. Ecological changes have favored the geographic expansion of the vector and, since the dengue pandemic in the Asian and Pacific regions, the infection became widely distributed worldwide, reaching Brazil in 1845. The incidence of dengue in Brazil has been frequently high, and the num...

  16. [The health system of Brazil].

    Montekio, Víctor Becerril; Medina, Guadalupe; Aquino, Rosana


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

  17. Light, distribution company in Brazil

    Since the publication of the Roulet Report, Electricite de France (EDF), the French group is crossing tormented hours. Despite its good financial results in 2004 with a turnover of 46.9 Mds euros its debts are around 19.7 Mds euros and are mainly due to its international investments which were not all very profitable. The first source of concern remains the Latin America markets and more particularly the Brazilian one which recorded 1.6 Md euros of losses. The future of EDF investment in Brazil, through its acquisition of the distribution company, Light, is uncertain. Within a new electric power industry framework, after currency devaluation and a rationing, Light is now in a catastrophic financial situation. The last tariff revisions given by the Brazilian authorities and the economic characteristics of the concession put the distributor at the edge of the bankruptcy. This article presents the situation of EDF group and Light at the end of 2004. The main question is the future of the Brazilian distributor in general and more particularly within the French group EDF. (author)

  2. US/Brazil joint pilot project objectives



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

  3. The victory against Greenpeace-Brazil

    The author writes down an interview with the President of the Brazilian association for nuclear energy (ABEN). ABEN has actively participated to the rebirth of nuclear energy in Brazil. During the beginning of the nineties Brazil underwent several anti-nuclear campaigns led by Greenpeace-Brazil, these campaigns found a favorable echo among the public because of the radiation accident of Goiania (1987) when a Cesium-137 source found in a dump site irradiated several families, killing 4 people, and of the technical difficulties that appeared during the first operating months of the Angra-1 nuclear power plant. The public controversy was so strong that it was in the air to stop the building work on the Angra-2 site. A counter campaign showing the dark sides of the Greenpeace organisation, opened the eyes to Brazilian politicians and now nuclear energy is re-established in the public esteem. (A.C.)

  4. Brazil's sugarcane boom could affect regional temperatures

    Schultz, Colin


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

  6. Indirect taxes on food in Southern Brazil

    Denize Mirian da Silva


    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.

  7. Challenges for malaria elimination in Brazil.

    Ferreira, Marcelo U; Castro, Marcia C


    Brazil currently contributes 42 % of all malaria cases reported in the Latin America and the Caribbean, a region where major progress towards malaria elimination has been achieved in recent years. In 2014, malaria burden in Brazil (143,910 microscopically confirmed cases and 41 malaria-related deaths) has reached its lowest levels in 35 years, Plasmodium falciparum is highly focal, and the geographic boundary of transmission has considerably shrunk. Transmission in Brazil remains entrenched in the Amazon Basin, which accounts for 99.5 % of the country's malaria burden. This paper reviews major lessons learned from past and current malaria control policies in Brazil. A comprehensive discussion of the scientific and logistic challenges that may impact malaria elimination efforts in the country is presented in light of the launching of the Plan for Elimination of Malaria in Brazil in November 2015. Challenges for malaria elimination addressed include the high prevalence of symptomless and submicroscopic infections, emerging anti-malarial drug resistance in P. falciparum and Plasmodium vivax and the lack of safe anti-relapse drugs, the largely neglected burden of malaria in pregnancy, the need for better vector control strategies where Anopheles mosquitoes present a highly variable biting behaviour, human movement, the need for effective surveillance and tools to identify foci of infection in areas with low transmission, and the effects of environmental changes and climatic variability in transmission. Control actions launched in Brazil and results to come are likely to influence control programs in other countries in the Americas. PMID:27206924

A successful continental Aedes aegypti control program in the Americas, has been able to eradicate the vector in most countries in the 60's, but the program could not be sustained along the years. Dengue viruses were reintroduced in the American region and the infection became endemic in Brazil, like in most Central and So...

  9. Class, race, and social mobility in Brazil

    Carlos Antonio Costa Ribeiro


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

  10. Family therapy in Brazil: current status.

    Picon, Felipe


    In the last three decades there has been a noticeable trend in the redefinition of the nuclear family in Brazil. A recent increase in the rates of divorces and paradoxically also in the rates of marriages, the legalization of same-sex unions and adoption by these couples, and the phenomenon of teenage pregnancy are some of the aspects that reflect on the current Brazilian family. This review highlights these changes and describes how family therapists in Brazil are facing the challenge of assisting these families, in a continental-sized country with uneven distribution of training courses and healthcare assistance.

    Hogan Daniel Joseph


    Full Text Available In its first part, the text examines the evolution of research on demographic dynamics and environmental change in Brazil. While concern for the deforestation of the Amazon region was an important starting point for the concerns of demographers, the first systematic studies dealt with the "brown agenda." It was a question of urban environmental quality which motivated specialists to enter this field. In the second part, the text presents a preliminary analysis of demographic dynamics in the principal ecological formations of Brazil, with considerations on the relationships between processes of population distribution and environmental sustainability.

  13. Hard times for Brazil's nuclear programs

    Brazilian scientists are strongly criticizing their government's ability to manage nuclear technology since the accidental release of highly radioactive cesium from a cancer therapy machine. the machine had been abandoned and was opened up by scavengers. Four people died and several others were exposed before the spill was contained. A joint statement issued by two of Brazil's main science organizations calls for the restructuring of Brazil's Commission for Nuclear Energy so that it no longer controls both the development and the regulation and licensing of nuclear energy

  14. Will Brazil's cars go on the wagon?

    The use of ethanol as an alternative fuel for cars in Brazil, may shortly be reduced. Falling world oil prices have meant that ethanol, derived from sugar cane, following a fourteen year research program, has ceased to be a financially viable replacement for petrol. Although about a third of Brazil's cars are at present powered by ethanol, only substantial government subsidies could reinstate this fuel despite its reduced pollutant status. Government officials now predict that ethanol will become merely a petrol additive and production of ethanol cars will have stopped by the year 2000. (UK)

    Fast reactor activities in Brazil have the objective of establishing a consistent knowledge basis which can serve as a support for a future transitions to the activities more directly related to design, construction and operation of an experimental fast reactor, although its materialization is still far from being decided. Due to the present economic difficulties and uncertainties, the program is modest and all efforts have been directed towards its consolidation, based on the understanding that this class of reactors will play an important role in the future and Brazil needs to be minimally prepared. The text describes the present status of those activities, emphasizing the main progress made in 1996. (author)

  17. The sustainability of hydropower projects in Brazil

    de Methodio Maranhao Neto, Gil; Yana, Laurent


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

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

    Valberg, Anna Helene


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

  20. Dengue situation in Brazil by year 2000

    Hermann G Schatzmayr


    Full Text Available Dengue virus types 1 and 2 have been isolated in Brazil by the Department of Virology, Instituto Oswaldo Cruz, in 1986 and 1990 respectively, after many decades of absence. A successful continental Aedes aegypti control program in the Americas, has been able to eradicate the vector in most countries in the 60's, but the program could not be sustained along the years. Dengue viruses were reintroduced in the American region and the infection became endemic in Brazil, like in most Central and SouthAmerican countries and in the Caribbean region, due to the weaning of the vector control programs in these countries. High demographic densities and poor housing conditions in large urban communities, made the ideal conditions for vector spreading. All four dengue types are circulating in the continent and there is a high risk of the introduction in the country of the other two dengue types in Brazil, with the development of large epidemics. After the Cuban episode in 1981, when by the first time a large epidemic of dengue hemorrhagic fever and dengue shock syndrome have been described in the Americas, both clinical presentations are observed, specially in the countries like Brazil, with circulation of more than one dengue virus type. A tetravalent potent vaccine seems to be the only possible way to control the disease in the future, besides rapid clinical and laboratory diagnosis, in order to offer supportive treatment to the more severe clinical infections.

  7. Environmental sustainability of biodiesel in Brazil

    Biodiesel production in Brazil has grown from 736 m3 in 2007 to 2.7 Mm3 in 2012. It is an emergent bioenergy for which it is important to guarantee environmental sustainability. The objective of this article is to characterise the biodiesel production chain in Brazil, to identify potential environmental impacts and to analyse key drivers and barriers for biodiesel environmental sustainability. This article explores these aspects and focusses on the increasing demand for the main feedstocks for biodiesel production in Brazil: soybean oil and beef tallow. The impacts of land use and land-use change on greenhouse gas emissions, biodiversity and water, as well as the energy balance, were found to be critical for the environmental sustainability assessment and development of biodiesel chains. Increasing agriculture yields, diversifying feedstocks and adopting ethyl transesterification can contribute to minimise environmental impacts. It was also found that environmental impacts could be mitigated by appropriate policies aiming at an integrated optimisation of food and bioenergy production and through agro-economic–ecological zoning, allowing adequate use of land for each purpose. Despite the limitation and weakness of some sustainability tools and initiatives, certification and zoning can play an important role in the sustainability of the emerging biodiesel production in Brazil

  8. Pentecostalism and premarital sexual initiation in Brazil

    Ana Paula A. Verona


    Full Text Available Pentecostal denominations in Brazil are recognized for their promotion of conservative norms and punitive sanctions related to the sexual behavior of their young members. Moreover, they have created unique space for their followers to actively participate in a religious environment. Using data from the PNDS-2006 (National Survey on the Demography and Health of Children and Women, Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher de 2006, we examine the associations, in Brazil between religion, as measured by religious affiliation and attendance at religious services, and premarital adolescent sexual initiation. Our main results confirm a strong association between delay in sexual initiation and Pentecostalism in Brazil and suggest that this association be related to frequent attendance at religious services. These findings are intriguing, especially because Pentecostalism has emerged and concentrated among socioeconomically disadvantaged populations, including the least-educated women, with lower income, and residents of urban areas. We conclude by suggesting that religion may be taking the place of family and school in communication on adolescent sexual behavior in Brazil. This hypothesis should be carefully investigated, since the religious teachings may sometimes be in favor of what families and the state see as beneficial for adolescents and youth in general, but sometimes in disaccord.

The problems to be overcome in the further extension of this technology are discussed: lack of trained experts, availability of financial loans, manufacture of bioreactors and accessory equipment, and research objectives.

  15. Passatempo Virus, a Vaccinia Virus Strain, Brazil

    Leite, Juliana A.; Drumond, Betânia P.; Trindade, Giliane S; Zélia I P Lobato; da Fonseca, Flávio G.; dos Santos, João R.; Madureira, Marieta C.; Guedes, Maria I.M.C.; Ferreira, Jaqueline M. S.; Bonjardim, Cláudio A.; Ferreira, Paulo C. P.; Kroon, Erna G.


    Passatempo virus was isolated during a zoonotic outbreak. Biologic features and molecular characterization of hemagglutinin, thymidine kinase, and vaccinia growth factor genes suggested a vaccinia virus infection, which strengthens the idea of the reemergence and circulation of vaccinia virus in Brazil. Molecular polymorphisms indicated that Passatempo virus is a different isolate.

  16. Ethnozoology in Brazil: current status and perspectives

    Alves Rômulo RN


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

  19. Abortion in Brazil: legislation, reality and options.

    Guedes, A C


    Abortion is illegal in Brazil except when performed to save the woman's life or in cases of rape. This paper gives a brief history of parliamentary and extra-parliamentary efforts to change abortion-related legislation in Brazil in the past 60 years, the contents of some of the 53 bills that have been tabled in that time, the non-governmental stakeholders involved and the debate itself in recent decades. The authorities in Brazil have never assumed full public responsibility for reproductive health care or family planning, let alone legal abortion; the ambivalence of the medical profession is an important obstacle. Most politicians avoid getting involved in the abortion debate, but the majority of bills in the 1990s have favoured less restrictive legislation. Incremental legislative and health service changes could help to improve the situation for women. Advocacy is probably the most important action, to promote an environment conducive to change. Clandestine abortion is a serious public health problem in Brazil, and the inadequacy of family planning services is one of the causes of this problem. The solutions should be made a priority for the Brazilian public health system. PMID:11424252

  20. Status of Research Reactor Utilization in Brazil

    Brazil has four research reactors in operation: the IEA-R1, a pool type research reactor of 5 MW; the IPR-R1, a TRIGA Mark I type research reactor of 100 kW; the ARGONAUTA, an Argonaut type research reactor of 500 W; and the IPEN/MB-01 a critical facility of 100 W. Research reactor utilization has more than fifty years in Brazil. The first three reactors, constructed in the late 50's and early 60's at university campus in Sao Paulo, Belo Horizonte and Rio de Janeiro, had their utilization for training, teaching and nuclear research. The IPEN/MB-01, designed and constructed in IPEN in the late 80's, is utilized for the development and qualification of reactor physics calculation for PWR core application. The IEA-R1 has had its application and utilization increased through the years and it is presently used for radioisotope production, neutron beam application, neutrongraphy, neutron activation analysis, and limited fuel and material irradiation tests, besides the regular use for training and teaching. The low power of the reactor and the lack of hot cells for post irradiation analysis limits its technical application for the nuclear fuel industry. Brazil has two nuclear power plants in operation, one unit starting construction and four more units planned for the next two decades. Brazil has significant quantities of uranium ore and has expertise in all the fuel cycle steps, including uranium enrichment, and produces the fuel assemblies for the nuclear power plants. These industrial activities demand the need of material and fuel irradiation tests. IPEN produces radiopharmaceutical kits for the treatment of more than three million patients each year. The majority of the radiopharmaceutical kits is produced from imported radioisotopes. The increasing price and shortage of world supply of 99mTc leads also to the need of increasing the radioisotope production in Brazil. Due to these new demands, the Brazilian Nuclear Energy Commission is analyzing the costs and benefits

  1. Biochar: An emerging policy arrangement in Brazil?

    Highlights: • The Brazilian biochar debate is driven by Embrapa experts. • The dominant ADE/biochar discourse has been replaced by biochar/technology discourse. • The international biochar/climate change discourse hardly resonates in Brazil. • Biochar topic is not covered by any formal procedure in Brazil so far. - Abstract: Biochar, the solid product of pyrolysis, has emerged as a new technology and policy tool to address various environmental challenges (climate change, food production and agricultural waste management). The concept of biochar drew its inspiration from Amazonian practices that had led to the creation of Amazonian Dark Earth (ADE): fertile soils rich in (bio)char and human artefacts. In this article, we conceptualize biochar as an emerging policy arrangement, and examine it along the four dimensions of the Policy Arrangement Approach (PAA), which are actors, discourse, power and rules. We focus on Brazil as an important player in the international biochar debate. Our analysis shows that science experts are the predominant players in the network, while policy-makers, businessmen and farmers are marginally positioned. Experts from Embrapa occupy central positions and thus exercise most power in the network. Moreover, experts linked to ADE have lost prominence in the network. The reason for this is to be found in the shift from the ADE/biochar to the biochar/technology discourse. The latter discourse includes different coalitions such as ‘climate change mitigation’, the ‘improvement of soil fertility’ and ‘improving crop residue management’. Although the biochar/climate coalition is dominant at the international level, it is far less prominent in Brazil. Nationally, it is particularly the discourses of ‘improvement of soil fertility’ and ‘improving crop residue management’ which have prompted actors’ relationships and practices. However, the biochar/technology discourse has not (yet) been formally institutionalized in

  2. Demand for fisheries products in Brazil

    Daniel Yokoyama Sonoda


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

  3. Allergens from Brazil nut: immunochemical characterization.

    Bartolomé, B; Méndez, J D; Armentia, A; Vallverdú, A; Palacios, R


    The increase in the consumption of tropical nuts in the Northern Hemisphere during the last years, has evolved in a simultaneous enhancement of allergic IgE mediated (Hypersensitivity type 1) reported cases produced by this kind of food. The Brazil nut is the seed of the Bertholletia excelsa tree (Family Lecythidaceae) and, as in other seeds, proteins represent one of its major components making up 15-17% of its fresh weight and 50% of defatted flour. Of these, storage proteins are the most important ones, and the 12 S globulin legumin-like protein and the 2 S albumin have been described as the most representative. The 2 S protein, due to its high sulfur-rich amino acid content (3% cysteine and 18% methionine), is being studied, cloned and expressed in some important agronomic seeds (soybean, bean, oilseed rape) in order to enrich the nutritional quality of them. The case of a patient with serious clinical allergic symptoms (vomiting, diarrhoea and loss of consciousness) caused by oral contact with the Brazil nut, is presented. The patient gave a positive Skin Prick Test response to Brazil nut, kiwi and hazelnut extracts, and negative to regionally specific aeroallergens and other food extracts. The patient serum showed a high level of specific IgE by RAST to Brazil nut (> 17.5 PRU/ml, Class 4), and significative levels to hazelnut, and mustard. In vitro immunological studies (SDS-Immunoblotting and IEF-Immunoblotting) revealed IgE-binding proteins present in the extract. It was shown that not only the heavy (Mr 9) and light (Mr 4) subunits of the known allergenic 2 S albumin but also the alpha-subunits (Mr approximately 33.5 and 32) and at least one of the beta-subunits (Mr approximately 21) of the 12 S Brazil nut globulin, hitherto never involved in allergic problems, showed a strong IgE-binding capacity.

  5. Optimum energy re-establishment in distribution systems: a comparison between the search performance using fuzzy heuristics and genetic algorithms; Restabelecimento otimo de energia em sistemas de distribuicao: uma comparacao entre o desempenho de busca com heuristica fuzzy e algoritmos geneticos

    Delbem, Alexandre C.B.; Bretas, Newton G. [Sao Paulo Univ., Sao Carlos, SP (Brazil). Dept. de Engenharia Eletrica; Carvalho, Andre C.P.L.F. [Sao Paulo Univ., Sao Carlos, SP (Brazil). Dept. de Ciencias de Computacao e Estatistica


    A search approach using fuzzy heuristics and a neural network parameter was developed for service restoration of a distribution system. The goal was to restore energy for an un-faulted zone after a fault had been identified and isolated. The restoration plan must be carried out in a very short period. However, the combinatorial feature of the problem constrained the application of automatic energy restoration planners. To overcome this problem, an heuristic search approach using fuzzy heuristics was proposed. As a result, a genetic algorithm approach was developed to achieve the optimal energy restoration plan. The effectiveness of these approaches were tested in a simplified distribution system based on the complex distribution system of Sao Carlos city, Sao Paulo State - southeast Brazil. It was noticed that the genetic algorithm provided better performance than the fuzzy heuristic search in this problem. 11 refs., 10 figs.

  6. Methodology to guide the expansion of natural gas distribution network through the identification of potential demand based on the use of urban land; Metodologia de suporte a expansao da rede de distribuicao de gas natural atraves da identificacao da demanda potencial com base no uso do solo urbano

    Bandeira, Maria Ines V.Q.B.; Arruda, Joao Bosco F. [Universidade Federal do Ceara (UFC), Fortaleza, CE (Brazil)


    The search for sustainability and the largest efficiency in the energy supply has implied in the gradual substitution of the electric power source for the use of the Natural Gas in the residential, automotive, services and industrial sectors. This paper reports a study which aims at the construction of a methodology to support the expansion of the Natural Gas distribution network using concepts of Space Syntax Theory. Through the analysis of the geographical location of urban land use activity system it is expected to define priority roadway routes in terms of potential demand for Natural Gas. A case study is on process in Fortaleza city, in the Northeastern Brazil, which is adequate to such an approach given its disperse density pattern and the present low scale of Natural Gas use in the four above mentioned urban sectors.

  7. Canine vector-borne diseases in Brazil

    Dantas-Torres Filipe


    Full Text Available Abstract Canine vector-borne diseases (CVBDs are highly prevalent in Brazil and represent a challenge to veterinarians and public health workers, since some diseases are of great zoonotic potential. Dogs are affected by many protozoa (e.g., Babesia vogeli, Leishmania infantum, and Trypanosoma cruzi, bacteria (e.g., Anaplasma platys and Ehrlichia canis, and helminths (e.g., Dirofilaria immitis and Dipylidium caninum that are transmitted by a diverse range of arthropod vectors, including ticks, fleas, lice, triatomines, mosquitoes, tabanids, and phlebotomine sand flies. This article focuses on several aspects (etiology, transmission, distribution, prevalence, risk factors, diagnosis, control, prevention, and public health significance of CVBDs in Brazil and discusses research gaps to be addressed in future studies.

  9. [Secular trends in breastfeeding in Brazil].

    Venancio, Sonia Isoyama; Saldiva, Sílvia Regina Dias Médici; Monteiro, Carlos Augusto


    The objective of this study was to document the secular trend in breastfeeding in Brazil. Data bases from seven national surveys conducted from 1975 to 2008 were reanalyzed. To obtain compatible data from the different surveys, children in the same age group and the same indicators were analyzed, using the same statistical techniques. The median duration of breastfeeding increased from 2.5 to 11.3 months, and the prevalence of exclusive breastfeeding in infants under six months of age increased from 3.1% to 41.0% in the period. The results indicate important challenges in accelerating the rhythm at which this practice in Brazil moves towards meeting international recommendations. PMID:24626558

  11. Argentina and Brazil: an evolving nuclear relationship

    Argentina and Brazil have Latin America's most advanced nuclear research and power programs. Both nations reject the Non-Proliferation Treaty (NPT), and have not formally embraced the Tlatelolco Treaty creating a regional nuclear-weapon-free zone. Disturbing ambiguities persist regarding certain indigenous nuclear facilities and growing nuclear submarine and missile capabilities. For these, and other reasons, the two nations are widely considered potential nuclear weapon states. However both nations have been active supporters of the International Atomic Energy Agency (IAEA) and have, in recent years, assumed a generally responsible position in regard to their own nuclear export activities (requiring IAEA safeguards). Most important, however, has been the advent of bilateral nuclear cooperation. This paper considers the evolving nuclear relationship in the context of recent and dramatic political change in Argentina and Brazil. It discusses current political and nuclear developments and the prospects for maintaining and expanding present bilateral cooperation into an effective non-proliferation arrangement. (author)

  12. Genetic diversity of noroviruses in Brazil

    Julia Monassa Fioretti


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

  13. Observing exoplanets from Brazil: the first try

    Saito, Roberto; Silva, Paulo Henrique; Kanaan, Antonio; Schoenell, William; Fraga, Luciano; Bruch, Albert


    This project consists in mapping a 4-square-degree region searching for exoplanets using the transit method. This “mini-survey” will be the first use of the 16″ robotic telescope developed by Universidade Federal de Santa Catarina (UFSC-Brazil) and Laboratório Nacional de Astrofísica (LNA/MCT-Brazil). The chosen region is over the Columba constellation and our first observations have shown that we have enough signal-to-noise ratio to search for transits on about 20,000 stars with ~13 < I < 16 mag, a magnitude range between the OGLE and HAT projects. In this star sample we expect to find about a dozen planets with transits duration of 1-3 hours and magnitude depth from 0.001 to 0.010 mag. As for other projects, all information will became public as a VO service.

  14. A report about Zika virus in Brazil

    Rosangela Cipriano


    Full Text Available Zika vírus, a Flavivirus first isolated in Africa, has spread to many countries around the world including Brazil. In this country, seven months after the football world cup, it was registered the occurrence of a epidemic, subsequently related to cases of microcephaly and Guillain-Barré syndrome. The virus is transmited via mosquito from Aedes genus, often following the bite from an infected vector. The febrile disease is self-limited, and there is no specific treatment. Few months after this outbreak in Brazil, the authorities recognized the relationship between the Zika vírus and the occurrence of Guillain Barré syndrome and microcephaly in newborns, correponding to fetal cerebral malformation or brain lesions. This finding is being a worldwide alert for strengthening the preventive measures, restricted to prevent insect bites and care for the environment.

  15. The legacy of monazite processing in Brazil

    The exploitation of natural resources containing naturally occurring radionuclides may lead to enhanced levels of radioactive isotope and enhanced potential for exposure to naturally occurring radionuclides in products, by-products, residues or wastes. Such resources include, for instance, monazite, the processing of which, in Brazil, generated a great amount of radioactive residues, being stored in buried concrete tanks, in temporary storage buildings and in sealed trenches. In addition, during the 1980's there were no radiological protection rules concerning the storage and transportation of these kinds of residues. Mineral radioactive residues were used as landfills and the residues of chemical processes contaminated floors and buildings. The decommissioning process and cleaning of old plants have generated tons of wastes that has been added to previously produced wastes. This paper reports and discusses the cycle of monazite in Brazil and its consequences in terms of site remediation and amount of wastes and residues generated and stored. (authors)

  6. Medical and occupational exposures in Brazil

    It is evident from statistical reviews of medical exposure in Brazil that appropriate standards of availability and quality of diagnostic X ray examinations are not reached. Furthermore, the effectiveness of worker protection could be improved by more frequent use of more efficient personal monitoring. An analysis of the distributions of individual exposures and, consequently, the initiation of an optimisation process would enhance dose limitation. (Author)

In the empirical model, the number of migrants between Brazilian mesoregions was the response variable. Many socioeconomic and criminal aspects of the origin and the destiny of t...

  9. "Labor Turnover and Labor Legislation in Brazil"

    Gustavo Gonzaga


    One of the main characteristics of the Brazilian labor market is its impressively high job and worker turnover rates. Although labor legislation in Brazil is very restrictive, dismissal costs are not high when compared with other Latin American countries. Moreover, many authors argue that the design of some job security programs creates perverse incentives that generate labor turnover. The objective of this paper is twofold. First, we describe Brazilian labor legislation, with emphasis on job...

    The author examines settlement patterns and urbanization of the remote area of Roraima State, Brazil. "A survey conducted in the capital city, Boa Vista, provides information on migration histories and migrants' characteristics.... Current views of urbanization of the Amazon [region] are focused on the displacement factor that development and state geopolitics have upon rural settlements...." The author also suggests that more attention needs to be paid to the characteristics of migrants in the urban areas. (EXCERPT) PMID:12294841
