  1. Geostatistical and stratigraphic analysis of deltaic reservoirs from the Reconcavo Basin, Brazil; Analise estratigrafica e geoestatistica de reservatorios deltaicos da Bacia do Reconcavo (BA)

    Energy Technology Data Exchange (ETDEWEB)

    Soares, Carlos Moreira


    This study presents the characterization of the external geometry of deltaic oil reservoirs, including the description of their areal distribution using geo statistic tools, such as variography and kriging. A high-resolution stratigraphic study was developed over a 25 km{sup 2} area, by using data from 276 closely-spaced wells of an oil-producer field from the Reconcavo Basin, northeastern Brazil. The studied succession records the progressive lacustrine transgression of a deltaic environment. Core data and stratigraphic cross sections suggest that the oil reservoirs are mostly amalgamated, delta-front lobes, and subordinately, crevasse deposits. Some important geometrical elements were recognized by the detailed variographic analysis developed for each stratigraphic unit (zone). The average width for the groups of deltaic lobes of one zone was measured from the variographic feature informally named as hole effect. This procedure was not possible for the other zones due to the intense lateral amalgamation of sandstones, indicated by many variographic nested structures. Net sand krigged maps for the main zones suggest a NNW-SSE orientation for the deltaic lobes, as also their common amalgamation and compensation arrangements. High-resolution stratigraphic analyses should include a more regional characterization of the depositional system that comprises the studied succession. On the other hand, geostatistical studies should be developed only after the recognition of the depositional processes acting in the study area and the geological meaning of the variable to be treated, including its spatial variability scales as a function of sand body thickness, orientation and amalgamation.

    A higher application of bioenergy is one of the existing ways to adequate the necessity of an expansion in the energy supply with the mitigation of global warming. The consumption of biofuel in the transport sector is the most usual and important use of biomass, however, bioenergy may also have a relevant contribution to the world electrical matrix. A comparative analysis shows that Brazil has consolidate the usage of biofuel while Europe is having problems to accomplish the biofuels levels established in the European Union guidelines. However, some european countries are developing their bioelectrical generation potential in a much more efficient way than Brazil. Therefore , brazilian policies to support bioelectricity should observe the successful instruments applied in Europe. (author)

    Renewable energy have a prominent place among the solutions to combat global warming, but its potential is still untapped in Brazil. Without long-term policies with clear rules, you can not attract entrepreneurs and ensure stability of operation of this market. The main tools of government to promote renewable energy generation have not been efficient - the Incentive Program for Alternative Sources of Energy (Proinfa) was implemented in 2002 but put into operation just over two thirds of the energy proposal. The low success rate in repeated auctions focused on renewable energy. The objective of this paper is to discuss the prospects of the expansion of electricity generation by renewable energies in Brazil and some fundamental requirements for effective structuring of this market in the country. This argument is supported by the analysis of the proposed mechanisms used internationally and in the country, under a new law for renewable energies. As a practical demonstration of the analysis, we present a simulation of conditions of formation of the final price of renewable resources in different conditions as varied market rate of return, cost of transmission, and sale of carbon credits.

    In recent years, the exploratory interest on Cumuruxatiba Basin has been inconstant, with modest discoveries of oil. Aiming to deepen the geological knowledge of the basin and in order to attract the interest of oil companies, the ANP (National Agency of Petroleum, Natural Gas and Biofuels) signed contract with COPPE/UFRJ for carrying out an analysis basin project. The project was developed by the Basin Analysis Multidisciplinary Modeling Laboratory (Lab2M/UFRJ) in the period 2006/2007, and was with the main objective outline the main structural and seismo-stratigraphic features of the basin, and in an integrated and multidisciplinary way, build a model of its sedimentation and tectono-stratigraphic evolution. This paper presents the results of the regional seismic mapping, aided by well and potential methods data. The stratigraphic succession the basin has been divided into genetic units (UN-B, UN-C e UN-D) corresponding to second order depositional sequences, they are: UN-B, corresponding by a rift and sag-rift siliciclastic deposits, plus the Aptian evaporitic deposits; UN-C, characterized by carbonatic deposits, and shelf related sediments; and UN-D, corresponding by a final transgressive (siliciclastic) - regressive (mix) cycle, between Cenomanian and actual days.

    Brazil, a continental country, with actually more than 150,000 workers under individual monitoring for ionizing radiation, has implemented in 1987 a centralized system for storage of external occupational dose. This database has been improved over the years and is now a web-based information system called Brazilian External Occupational Dose Management Database System - GDOSE. This paper presents an overview of the Brazilian external occupational dose over the years. The estimated annual average effective dose shows a decrease from 2.4 mSv in 1987 to about 0.6 mSv, having been a marked reduction from 1987 to 1990. Analyzing by type of controlled practice, one sees that the medical and dental radiology is the area with the largest number of users of individual monitors (70%); followed by education practices (8%) and the industrial radiography (7%). Additionally to photon whole body monitoring; neutron monitors are used in maintenance (36%), reactor (30%) and education (27%); and extremity monitors, in education (27%), nuclear medicine (22%) and radiology (19%). In terms of collective dose, the highest values are also found in conventional radiology, but the highest average dose values are those of interventional radiology. Nuclear medicine, R and D and radiotherapy also have average annual effective dose higher than 1 mSv. However, there is some very high dose values registered in GDOSE that give false information. This should be better analyzed in the future. Annual doses above 500 are certainly not realistic. (author)

    The energetic analysis is the traditional method of quantification of the energy used in an operation involving physical and chemical processes and transference and/or conversion of energy. Generally used through energetic balance that is based on the first law of thermodynamics to evaluate the energetic efficiency. This balance is used to determine and reduce the loss of energy. Although an energy balance does not provide information about the energy degradation or resources during a process and do not quantify the potential or quality of the energy fluxes and material that flow in a system and come out as products and losses. The exergetic analysis goes beyond the limitations of the first law of thermodynamics. The concept of exergy is based in the second law of thermodynamics. The objective of this paper is to compare the more suitable analysis method aiming the identification of the energy economy potentials and consequently the reduction in the emissions of the greenhouse gases, through the balance of mass, energy and exergy of the blast furnace 1 of V and M do Brazil.

    Nowadays, the intense investment in renewable energy reflects the search for alternative solutions to politician-economic and socio-environment originated by energy' source predominance of fossil origin in the global energy matrix. In this case, the ethanol from Brazil's sugar cane is more and more writing your history on the International bio fuels market. That's mainly due to Brazil's commercial maturity, agricultural, technological achieved in last decades. However, some negatives socio environments, such as deforestation, fires and precarious job conditions, among others are a discredit for a probable future hegemony of Brazilian ethanol. In this way, it is important to set guide-line discussions about this topic, analyzing and overcoming problems that avoid a better sustainable posture. (author)

    This paper documents the analysis of seismic data of the Espirito Santo basin obtained during the project realized through partnership between COPPE/UFRJ/Lab2M with the Agencia Nacional do Petroleo, Gas Natural e Biocombustiveis (ANP) during 2006 and 2007. The major objective of the seismic data interpretation in the project was to define the main structural and stratigraphic features in order to build a sedimentation model and a tectonic-stratigraphic evolution model of the Espirito Santo basin. Thus, the sedimentary package has been divided into eight genetic units (UN), grouped into five third order stratigraphic sequences, namely: UN-B, represented by siliciclastics rocks of the rift stage and evaporitic sag-rift stage, deposited during the Aptian; UN-C, which represents the carbonatic rocks deposited in a marine environment, and siliciclastics rocks located in the proximal portions during the Albian; and UN-D, represented by sediments, composed mainly by pelites, deposited in between the Cenomanian and Recent, and includes the Eocene volcanic event, which one changed the sedimentation pattern of the basin.

    Achao, Carla da Costa Lopes


    Introduced at the end of the 1970s to study the impacts of structural changes on electricity consumption by industry, index decomposition analysis techniques have been extended to various other areas to help in the formulation of energy policies, notably in developed countries. However, few authors have applied these techniques to study the evolution of energy consumption in developing countries. In Brazil, the few available studies have focused only on the industrial sector. In this thesis, we apply the decomposition technique called the logarithmic mean Divisia index (LMDI) to electricity consumption of the Brazilian residential sector, to explain its evolution in terms of the activity, structure and intensity affects, over the period from 1980 to 2007. The results obtained in a preliminary analysis point out, in a general way, that the observed variables in electricity consumption in the Brazilian residential sector are, mainly, the product of the increase in the number of consumers and the changes in the specific consumption of electricity in households. In a further analysis, carried out when the structure is given through consumers participation in consumption categories (Low Income and Conventional) taken from an overall point of view, although the intensity and activity effects may be considered the main explaining factors in consumption variation, the structure effect stands out in the period immediately after the 2001 rationing, as a reflect of the changes in the inclusion criteria in the Low Income category, specifically in the Northeast.

    The main fuels for vehicles in Brazil are the gasoline type C - which is a mixture of gasoline, resulting from the fractional distillation of oil and anhydrous ethanol - and hydrated ethanol. For this importance, has been created an institutional framework to guide and regulate the activities of the fuel sector, initially for gasoline, hydrated ethanol was contemplated by such device in 2011. Since 2003, there has been manufactured in Brazil the flex-fuel vehicles. With this, the possibility of activation of an additional factor for the regulation of vehicle fuel prices, increasing consumer power to define which of the fuels could be used as the disposition of their prices. One of the effects of growth flex-fuel sales has been increased production and investment in ethanol (especially sugar cane) as a suitable alternative to the. The hope was that the formation of fuel prices was less dependent on their cost of production and distribution and more influenced by a pressure of consumer demand. However, the increase in the sales of the flex-fuel vehicle in Brazil in the last years was not the determining factor in the price of fuels, as it was expected. The explanation of this is on external factors to the automotive industry, linked to the structures of the production chain of oil and ethanol, especially the question of the great increase in international prices of oil and hydrated ethanol in the international market in recent years.

    The Brazilian electric energy matrix is mostly renewable. According to the Generation Information Base (BIG) of the Brazilian Electricity Regulatory Agency (ANEEL), hydroelectricity is responsible for 67.31% of the country's energy. The additional generation comes mostly from fossil fuels, whose use is questioned when it comes to environmental quality and climate change. Despite its abundance, hydroelectric power generation has physical, socioeconomic and environmental limitations. Thus, it is essential to develop alternative technologies, providing security in the supply of electric energy and the maintenance of a clean matrix. Among the alternative technologies available, wind power is the one that has been gaining prominence, domestically and internationally speaking. In the last auction of renewable sources held in August 2010 in Brazil, the energy produced by the plants of sugarcane bagasse (biomass) was traded at an average of R$ 144.20 MWh; wind energy, which was the cheapest, was traded at R$ 130.86, and the energy from small hydropower plants (PCH), at R$ 141.93 MWh. The wind power plants accounted for 70% of the auction, which resulted in a plan for increasing its installed capacity by fivefold, by the year 2013. Brazil has great potential to be explored (estimated 143,000 MW), yet despite being appealing, wind energy still face some challenges. One of them is due to the fact that most potential areas for such energy are found in permanently preservation areas and areas considered national assets, subject to special protection measures. This study aims to investigate whether the regulatory, legal and environmental issues are considered an obstacle to an effective inclusion of wind power generation in Brazil. The study examines the process of environmental licensing of wind power plants, especially those established in permanently preservation areas (APPs) and Coastal Areas. The research methodology consisted of normative framework, judicial decisions

    This thesis focuses on the technologies related to CO{sub 2} capture and geological storage. The main objective of this study is to perform an analysis of the technical potential of geological sequestration of CO{sub 2} in the oil and gas sector in Brazil. Climate changes are directly related to emissions of greenhouse gases. Mainly, are related to increased carbon dioxide emissions due to the use of fossil fuels. To mitigate climate changes there are technologies that have the purpose of promoting the reduction of emissions of greenhouse gases such as the Geological Sequestration of CO{sub 2}. Thus, the study presents a description of the stages of the geological sequestration of CO{sub 2} and the state of the art of the technology in Brazil and worldwide. In addition, is presented the capacity for storage of the Brazilian sedimentary basins. Finally, this thesis analyzes the application of the described technologies in two stationary sources of great importance: refineries and oil and gas production fields. (author)

    The recent moves towards the insertion of biofuels in the energy matrix of a number of countries are opening new prospects for agricultural production and for agroindustrial chains. This study aims at understanding the mechanisms taking place within a production system geared towards biodiesel production. The emergence of this new productive base raises new research issues: in what circumstances are the structuring, organization and implementation of these biodiesel productive chains taking place in Brazil? What are the effects of biodiesel production on local economies? Hence, the central objective of this study is the development and validation of an analytical structure capable of characterizing the biodiesel productive arrangements and identifying their economic and social impacts at the regions where they are installed. A preliminary analysis identified that a biodiesel productive arrangement is emerging in the State of Piaui, Northeastern Brazil, Our theoretical basis comprises elements from the regional economy, biorefineries, local production arrangements and innovation. For the analyses, we employed the methods of input-output, local quotient and shift-share. It can be said that a new social-economic dynamics is taking place in Piaui; however, the company needs to assess its interaction with local institutions as well as its castor bean production strategies.

    The internal lining in gas pipelines aims the reduction of roughness and, consequently, the friction factor, therefore resulting in a reduction of pressure drop in natural gas flowing. During Bolivia-Brazil gas pipeline basic design, the cost benefit of internal coating was analyzed, in terms of friction factor reduction and distances between Compressor Stations. It was observed an increase of transport capacity and reduction of compressors' power, thus leading to its utilization. Since the pipeline is already in operation, using a SCADA system with Advanced Functions, a comparison between the current real friction factor in the pipeline with that theoretical values used during the design phase becomes possible. Through this comparison, it is possible to evaluate internal coating's efficiency, quantifying its real benefit for gas pipelines. (author)

    International gas pipelines reflect a integrated commerce and impose a metrological challenge for the custody transferences that indistinctly imply in significant economic impact. This work argues the complex analysis of the mass balance and expression of uncertainties of the Gasoduto Bolivia-Brasil (3.150 Km of length, 557 Km in Bolivian territory and 2.593 Km that cross Brazil of West for East), today carrying approximately 60% from its maximum capacity (30 million of cubic meters daily), operating for the Transportadora Brasileira Gasoduto Bolivia Brasil S.A., a enterprise controlled by PETROBRAS Gas S/A (GASPETRO). The TBG measuring methods always taking care of the necessities of the customers as well as being lined up with the changes of the natural gas market. In six years of existence, the TBG came along with the legislation created for regulating agency in formation and adjusted to the establishment of the contract inspector, important landmarks of the evolution of the market. This work presents the definitions that guide the metrological subjects of the TBG, making use of efficient tools in answers for each demand and searching to satisfy its proper necessities, the necessities of its customers and the new demands of the regulating agency.

    This work presents a comparative analysis of the concession process of Oil and Gas Exploratory Blocks adopted in two countries of Latin America: Peru and Brazil, according to the rules of the Bidding Rounds occurred in 2007 (Peru's Bidding Round and 9th Bidding Round, respectively). In order to analyze the two models chosen, we considered, among others, the rules and proceedings adopted, the legal framework, the criteria used to qualify the companies, the number of blocks offered, the number of participating companies, the infra-structure of the event and the offer selection system. Through this analysis it was possible to verify the points which could be improved in each concession process model and it showed significant differences between them, despite the fact of each one is suitable to the reality of each country. It is important to highlight that the exchange of experience between agents of oil and gas sector, in this specific case Perupetro and ANP, contributes a lot to the continued improvement of bidding processes and other practices adopted.

    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 increasing expansion of compounding pharmacy associated with several reports on variances in the quality of compounded drugs demonstrates the need for verification of quality, safety and efficacy of these products. In this work, physical and chemical analyzes were performed to evaluate the quality of some capsules manipulated enalapril and simvastatin, acquired in five pharmacies in Belo Horizonte /Brazil. Among the analyzes are pharmacopoeial tests for appearance, identification, determination of weight, content, related compounds and uniformity of dosage units, and was also performed neutron activation analysis for the determination of inorganic impurities in drugs sampled. The results showed that 60% of the samples were unsatisfactory for pharmacopoeial tests. The contents of the capsules sampled for individual testing unit dose uniformity between 0% and 136.2%. This test is important in evaluating the quality, which influences the safety and efficacy of drug treatment, since it allows you to check if the product contains the proper dosage and necessary for successful pharmacotherapy. On the other hand, underdosing can lead to reduced or absent desired therapeutic response, and overdoses can provide an undesirable effects and even toxic. The concentration of inorganic impurities was considered to be relatively small. However, no specific limits for some chemical elements in medicine hamper a better thread. In addition, further studies must be performed to assess chronic exposure to low concentrations of inorganic impurities, since drugs can be continuously used, and other sources of exposure must also be considered in order to evaluate the risk. The problems related to the quality and safety of compounded drugs are still reality in the country and reveal a serious public health problem, especially regarding the lack of uniformity between the unit doses of medications. It is suggested that the competent authorities to sanitary products, propose changes in

    The volume of stranded natural gas global reserves is substantial and represents more than a third of the world's proven natural gas reserves. In Brazil, recent discoveries operated by PETROBRAS, with participation of other companies, show trend of stranded gas reserves incorporation, associated gas or not. This dissertation's main objective is to make a technical and economic analysis of the implementation of small-scale GTL technology for the exploitation of stranded associated natural gas offshore in Brazil. Thus, the dissertation held, initially, a survey of the processes of gasification and the manufacturers with technologies and projects based on these processes, for specific offshore applications. In a second stage, the conditions of the offshore environment were examined. After the confrontation of the technologies available and the operation conditions, a technological alternative has been chosen to be used in an illustrative economic analysis. The results show that GTL offshore option becomes viable at a minimum price of about US $ 40.00 / barrel. Although this value is greater than the robustness price adopted by PETROBRAS, there are prospects for the reduction of GTL technology costs. (author)

    The increased demand for natural gas leads to global integration of markets, leading to decisions that cover the various technologies of transportation, noting the specific locations. The transport of natural gas considered more traditional (Liquefied Natural Gas and Pipeline) often unviable economically areas of operation due to cost. In this case, there are alternative technologies to reduce those costs. The article is to compare the technologies of transport, using the methodology of the Net Present Value (VPL) to identify one that has more positive VPL, which is the most profitable. Thus, in search of validate the results of SUBERO et al. (2004) for gas transport by Pipelines, Liquefied Natural Gas and Compressed Natural Gas. In addition, they are compared these results with the method of VPL and with the economic analysis presented in using the payback period of CHANG (2001) and SANTAREM et al. (2007). It was found that the results obtained in Brazil were identical to those obtained by CHANG (2001) and SUBERO et al. (2007), saving only some differences in magnitude due to the specific characteristics of the Brazilian economy. In other words, for the Brazilian case, the technology of Compressed Natural Gas (CNG) was the most economically viable with the method of VPL, followed by technology, Pipeline and Liquefied Natural Gas (LNG), regardless of the interest rates of 10% and 6.5% and periods of 20 and 30 years. The contribution of this work is to show that despite of the method, payback or VPL, the various alternatives for transporting natural gas to Brazil have the same ranking and economic viability.

    The goal of this paper is to present the work in the thesis developed by Silva Jr. (2005) who discusses the application of the methodologies of Life Cycle Cost Analysis (LCCA) as a tool to propose energy efficiency standards, additional to the voluntary labels already existing in the one-door Brazilian refrigerators. Another objective is to study the role of these instruments (energy efficiency labels and standards and environmental labels) as means to supply technical subsidies for the establishment of maximum level of electric energy consumption and environmental quality impact for electrical equipment in Brazil. The LCCA methodology allows to evaluate the impacts of the energy efficiency increasing in electrical equipment, resulting in important saving (energy, financial, carbon dioxide emissions avoided etc.) for the country and its citizens. The results reached in this studies offer important data to subsidize deep discussions with manufacturers and the government to stipulate minimum energy efficiency standards for the Brazilian refrigerators. Thus, with increase of 28,1% on the energy efficiency of the one-door Brazilian refrigerators in 2008 to reach a values of savings that can be in order of 54,63 TWh (with respective reduction of demand power of 208 MW), of US$ 6,23 Billions of Dollar (R$ 17,2 Billions of Reais) of reduction in the account of electric energy for the population and of approximately 22 billions of tons of CO{sub 2} not emitted on the environment after 30 years of the implantation of standard. These values, that can not be despised by government, manufacturers and consumers. One other interest of this work is to start the discussion, the possibility of the creation of environmental labelling (e.g., Green Seal - USA, Eco-label - EU etc.) that is an additional program/methodology, which, it may be utilized as support for development of technologies and for the increase of energy and environmental efficiency of the electric equipment.

    The current actions of economic and industrial activities have resulted in increase of the concentration of greenhouse gases in the atmosphere since 1750. According to IPCC (2007) this alteration can increase the average temperature in the planet between 1,8 and 4,0 deg C up to 2100. The climate changes and the global warming are the most complicated environmental questions of our time and the actions took now will have effect on the future generations. In this context, a series of world-wide conferences and diverse scientific quarrels had occurred throughout the last decade, which culminated in the most important multilateral agreement firmed on climate changes, the Kyoto Protocol, signed in 1997. The Protocol is a landmark in the attempts of mitigation of the climate changes, since it established the commitment of the industrialized countries with emissions reduction targets of 5,2% to the level of 1990 emissions. To achieve such targets these countries count on three flexibilization mechanisms provided by the Kyoto Protocol: Joint implementation, Emission Trading and the Clean Development Mechanism (CDM) that it will be object of this study. The objective of this thesis is to carry through an evaluation of the CDM since its conception until the current days, searching to identify its dynamics and the main inherent gaps of this instrument and finally present two case studies of the bio diesel and wind energy uses in Brazil.

    The natural gas pipeline transport is carried out by one or more compression stations. Each station possesses one or more compressors. The compressor's fuel is usually natural gas itself. The amount of natural gas consumed by the compressors fluctuates daily according to the demand at the city-gates. The daily operational result of a pipeline is known as imbalance. The imbalance is the difference between the natural gas entering into a in a pipeline and the volume delivered in the city-gates added to system use gas. The imbalance analyses in a pipeline that uses natural gas powered compressors requires the analyses of the system use gas. The aim of this work is to study the system use gas in the Bolivia-Brazil pipeline using the available data from the Superintendencia de Comercializacao e Movimentacao de Petroleo, seus Derivados e Gas Natural - ANP and compare the change of the volume consumed before and after the entry into operation of the Campinas-Rio gas pipeline.

    The objective of this work is the study of the natural gamma radiation at the Areia Preta Beach (APB) in Guarapari, state of Espirito Santo, Brazil. The level of this radiation is dependent on the concentration of the radioactive mineral monazite in the sand. Probable risks of the exposure to gamma radiation at the APB were evaluated by the preliminary environmental risk analysis technique. For this purpose were conducted two annual sets monitoring gamma radiation in the APB every two months and so, acquired the seasonal variation of the radioactive levels. Additional/y was investigated the granulometry of the heavy mineral fraction and also carried out electronic microscopic scanning and radiometric age dating of the monazites of the APB, the mineral separation by magnetic susceptibility, and the mineralogic determination of the sediment. In order to gain a more complete picture of the seasonal variation, and, consequently, of the risk of exposure to ionizing radiation at the APB, the radiometric variation was also studied at some other beaches in the same region. The results indicate that the highest radiometric values are measured in summer and the lowest in winter. The radiometric dating of the monazites from the APB revealed the ages of 475 and 530 Ma. The Preliminary Hazard Analysis indicates a minimum risk of excessive radioactive exposition. It would take a period of approximately 870 years of a beach fully crowded to result in one case of bad consequences due to exposure to gamma radiation. (author)

    The region of Alfenas, in the state of Minas Gerais, Brazil, is predominantly constituted of Pre-Cambrian rocks with well developed alteration profiles in association with colluvial and alluvial sediments. No study to date has examined in detail its potential use in the ceramic industry. The scarce knowledge of its mineralogical and technological properties limits its value and consequently its industrial use. Until now, these clay materials have been used in a rudimental manner, in small scale in the fabrication of red tiles. The present study aimed at analyzing these clays mineralogically (X-ray diffraction), chemically (major and minor elements by X-ray fluorescence and organic carbon analysis) and technologically (pressing granulometric distribution; mechanical resistance; water absorption, apparent porosity; linear firing shrinkage; color of firing and others) in order to better understand the raw material and develop adequate technological applications. The best results of ceramic properties were the samples with higher organic content (more plastic clays) and higher values of Al{sub 2}O{sub 3} (kaolinite and gibbsite) and Fe{sub 2}O{sub 3} as well lower SiO{sub 2} content and finer grain size which contribute to a better sintering.

    Full Text Available A wide variety of opportunistic pathogens has been detected in the tubing supplying water to odontological equipment, in special in the biofilm lining of these tubes. Among these pathogens, Pseudomonas aeruginosa, one of the leading causes of nosocomial infections, is frequently found in water lines supplying dental units. In the present work, 160 samples of water, and 200 fomite samples from forty dental units were collected in the city of Barretos, State of São Paulo, Brazil and evaluated between January and July, 2005. Seventy-six P. aeruginosa strains, isolated from the dental environment (5 strains and water system (71 strains, were tested for susceptibility to six antimicrobial drugs most frequently used against P. aeruginosa infections. Susceptibility to ciprofloxacin, followed by meropenem was the predominant profile. The need for effective means of reducing the microbial burden within dental unit water lines is emphasized, and the risk of exposure and cross-infection in dental practice, in special when caused by opportunistic pathogens like P. aeruginosa, are highlighted.Uma ampla variedade de patógenos oportunistas tem sido detectadas nos tubos de alimentação de água dos equipos odontológicos, particularmente no biofilme formado na superfície do tubo.

    Full Text Available Die studie van Paulus se brief aan Filemon het gebaat by die hernude belangstelling in die retoriese analise van Nuwe-Testamentiese geskrifte, in die sin dat ’n groot aantal retoriese analises van die brief gepubliseer is. Hierdie retoriese analises is vanuit ’n verskeidenheid perspektiewe gedoen, maar tot dusver het niemand nog die manier sistematies ondersoek waarop die vierde-eeuse outeur, wat later die naam Ambrosiastergekry het, die brief in sy kommentaar op die Pauliniese briewe geïnterpreteer het nie. Hierdie artikel bied dus ’n oorsig van Ambrosiaster se interpretasie van die brief aan Filemon en dui aan watter bydrae dit tot die retoriese analise van die brief kan maak.   Ambrosiaster’s exposition of the Letter to Philemon and the rhetorical analysis of the letter. In recent times, the study of Paul’s letter to Philemon benefitted from the renewed interest in the rhetorical analysis of New Testament writings, in the sense that a large number of rhetorical studies of the letter have been published. These rhetorical analyses of the letter have been done from different perspectives, but thus far, no one has systematically investigated the way in which the fourth-century author, who was later called Ambrosiaster, interpreted the letter in his commentary on the Pauline letters. Accordingly, this article offers an overview of Ambrosiaster’s interpretation of the letter to Philemon, and then outlines the contribution that his reading of the letter can make to the rhetorical interpretation of it.

    Full Text Available Esse estudo avalia as consequencias de não se considerarem os efeitos da inflação nas analises das demonstrações contábeis e, além disso, se esses impactos são diferentes em cada setor da economia. A pesquisa considera apenas as empresas que divulgaram as suas demonstrações contábeis corrigidas no periodo de 1996 a 2002. Verificou-se a existência de diferença significativa entre indices calculados pela Lei Societária (sem corregAo e pela Correção Monetária Integral, tendo sido utilizado o teste de médias emparelhadas. Os resultados obtidos evidenciam que a falta de correção monetária nas demonstrações contábeis apresentadas de 1996 a 2002 pode causar distorções na análise da real condição patrimonial e financeira das empresas. Embora essas distorções não sejam igualmente percebidas em todos os setores e em todos os indices, elas podem resultar em conclusões equivocadas por parte dos usuários dessas informações.

  4. Spotlight: Brazil. (United States)

    Carter, M


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

    Remotely-operated SHRIMP dating of zircon is an interesting alternative for dating of zircon crystals. Although it does not represent any technical progress of the geochronological method using the U-Pb system in zircon it is a very useful and cheap facility. The procedure was first used for mass spectrometric analyses involving two international laboratories in Sao Paulo, Brazil and Beijing, China. It was applied to samples of three gneiss-migmatitic rocks from the Ita quarry in the Atuba Complex (located between the Luis Alves and the Apiai Domain) to test previous controversial hypotheses about its evolution. The presence of important archaean and paleo proterozoic components in the complex is confirmed by analyses of zircon found in probably neo proterozoic leucosomes. Diorite intrusion also occurred during the neo proterozoic, associated with the 0.6Ga continental collisions involved in the assembly of Gondwana. The determination of Hf isotope ratios by LA-ICP/MS represents a new option for checking the relative importance of mantle ({epsilon}{sub Hf} > 0) and crustal contributions (({epsilon}{sub Hf} < 0) during the growth of the zircon crystals. While the archaean component in the complex was derived from the mantle ({epsilon}{sub Hf} + 1.5 to + 8.7) the paleo proterozoic component had a crustal contribution ({epsilon}{sub Hf} - 9.1 to -10.1).

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

    The dissertation presents the aspects related to the restructuring of power systems in terms of international experiences, and the possible implications for the definition of the new power system in Brazil. The experience shows that the reform in various countries has started from the sector deverticalization, together with the transmissions open access scheme. The retrospect of researched countries indicates that the transmissions remuneration is based on a methodology that recovers the operative cost of transmission transactions, along with an additional amount that take into account the cost of the existing transmission system. The following countries have been analyzed: Chile, Norway, England and Argentina. This work also shows the current situation in Brazil, as in terms of tariffs, as regarding the power system organizational structure, as well as a preliminary proposal conceived by SINTREL (National System of Electrical Energy Transmission) to evaluate the transmission transaction cost. This dissertation ended with comments and conclusions, depicting a future program which might be followed, considering the aspects quoted above and the peculiarities of brazilian power system.

    The Fricke dosemeter has been used for absolute determination of the radiation dose between 40 and 350 Gy for X-rays, Gamma rays and fast electrons energies. The great inconvenient of that dosimetric system is the impossibility of using for measurements of exposure or low dose rates. A Fricke dosimetry system was implanted at the Nuclear Sciences Regional Center (CRCN), in Recife, Pernambuco state, Brazil, for the determination of radiation doses for spectrometry and mass dosimetry with plasma source. The statistical analysis of the obtained results have shown that using the spectrometric method that system cna be used for maintenance of factors of CRCN standard calibrations and the dose assessment thru mail system of radiotherapy centers of the country.

    Boaratti, Maria de Fatima Guerra


    Food borne diseases, in particular gastro-intestinal infections, represent a very large group of pathologies with a strong negative impact on the health of the population because of their widespread nature. Little consideration is given to such conditions due to the fact that their symptoms are often moderate and self-limiting. This has led to a general underestimation of their importance, and consequently to incorrect practices during the preparation and preservation of food, resulting in the frequent occurrence of outbreaks involving groups of varying numbers of consumers. Despite substantial efforts in the avoidance of contamination, an upward trend in the number of outbreaks of food borne illnesses caused by non-spore forming pathogenic bacteria are reported in many countries. Good hygienic practices can reduce the level of contamination but the most important pathogens cannot presently be eliminated from most farms, nor is it possible to eliminate them by primary processing, particularly from those foods which are sold raw. Several decontamination methods exist but the most versatile treatment among them is the ionizing radiation procedure. HACCP (Hazard Analysis and Critical Control Point) is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. For successful implementation of a HACCP plan, management must be strongly committed to the HACCP concept. A firm commitment to HACCP by top management provides company employees with a sense of the importance of producing safe food. At the same time, it has to be always emphasized that, like other intervention strategies, irradiation must be applied as part of a total sanitation program. The benefits of irradiation should never be considered as an excuse for poor quality or for poor handling and storage conditions, i.e.. as a substitute for good manufacturing practices. By adopting an HACCP based approach to food safety management, it can be clearly demonstrated that the application of a technology like food irradiation is essential for ensuring the safety of raw food stuffs. Such an intervention should be considered as a CCP (Critical Control Point) in the food chain. Therefore, the potential benefit of irradiation, which is endorsed by national and international bodies surely merits serious consideration by public health authorities, industry and consumer groups worldwide. For such, a system of HACCP and the irradiation is primordial so that the alimentary .safety is maintained processes if they are applied correctly. (author)

    The activity of poultry raising is today an alternative for income generation in the backlands of Pajeu, State of Pernambuco. In the City of Sao Jose do Egito, distant 402 km from the State Capital Recife, there is a large poultry plant with 284 integrated poultry farms owned by small rural producers. Those poultry farms are built in masonry and lateral woven wire fencing within the standard size of 9 m X 125 m. Their capacity is 10,000 birds and they are equipped with drinking and feed boxes, silos, fans, nebuliser, motor-pumps, lights and heaters. In their first 18 days of the bird's life, called 'baby chick phase', it needs a warm environment temperature of about 34 deg C, which is fundamental for its survival. In that phase the energy consumption is mainly related to water pumping and lighting. From the 19th day up to the 45th day - the period called 'poultry phase' - the birds need lower temperatures. The feeders are automatic, fans and nebulizers are used to ease the air circulation and to improve the poultry comfort. This phase is the one, which requires more electric energy consumption. After 45 days the poultry is slaughtered with about 2.8 kg and the poultry farm comes into a time period of cleaning and resting called 'cleaning and resting phase', which takes from 15 to 28 days. This is the phase with the lowest energy consumption. Then the poultry farm cycle is completed, which takes about 70 days, that is, the time span of one year accounts for 5.5 cycles. In this work an energy consumption analysis for all phases of poultry raising is performed and alternative proposals for the energy conservation and energy consumption reduction is presented.

    Energy Technology Data Exchange (ETDEWEB)

    Passarelli, Claudia Regina


    This work describes the geometric and kinematic characteristics of the Major Gercino Shear Zone (MGSZ) in the Canelinha-Garcia area. This shear zone is one of the major lineaments that affect all southern Brazilian precambrian terrains. In Santa Catarina State, it separates, along its whole extension, the supracrustal rocks of the Brusque belt (northern part) from the Granitoid belt (southern). This zone is characterized by a regional NE trend and a dextral sense of movement where ductile-brittle structures predominate. The MGSZ is composed of two mylonitic belts separated by granitoid rocks probably associated to the development of the shear zone. Both shear zones show cataclastic to ultra mylonitic rocks, but mylonites and protomylonites conditions at high strain rate. The calc-alkaline granitoids present in the area can be grouped in two granitoid associations with meta to peraluminous affinities. The Rolador Granitoid Association is characterized by grayish porphyritic biotite-monzogranites and the Fernandes Granitoid Association by coarsed-grained to porphyritic pinkish amphibole-syenogranites. The U-Pb and Rb-Sr ages range from 670 to 590 Ma with the Sr{sup 87} / Sr{sup 86} initial ratios suggesting a crustal contribution in the generation of these rocks. The importance of the pure shear component is also emphasized by the results of the Fry method. Many z axes of the strain ellipses are at high angle to the shear foliation. Symmetric porphyroclasts also corroborate this hypothesis. The micaceous minerals formed during the shear development indicate K-Ar ages around 555 {+-} 15 Ma. Brittle reactivations of the shear zone have been placed by K-Ar in fine-fraction materials at Triassic time (215 {+-} 15 Ma.) 220 refs., 107 figs., 18 tabs., 4 maps

    Energy Technology Data Exchange (ETDEWEB)



    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.

This model was applied to the period 1965-1977, in order to test it in the face of a new set of international crisis, such as the increase of petroleum prices, the devaluation of the dollar in relation to the currencies of other industrial countries, and the low growth-rate of the world economy, as well as in the face of the changes in Brazil's foreign economic policy. An alternative model was also tested for econometric applicability to the actual situation of foreign trade. It was observed, in the end, that the models studied sufficiently demonstrated that the improvement of our balance of trade is subject to such external variables as world income and import-export prices, as well as to the internal variable of exchange rate.

    Full Text Available The dynamics of the arboreal structure of a Mixed Rain Forest was assessed in the period 1992-2003. The area belongs to the “Florestal Gateados company”, located in Campo Belo do Su county, in Santa Catarina State, Southern Brazil. The surwey was carried out in 16 sample units of 10 x 60 m (600 m², where all individuals with DAP > 10 cm Were registered, measured and identified. After the analysis, it could be concluded that: Lithraea brasiliensis was the most representative specie in the structure of the forest in both analised periods, and this was related to the high values of density, dominance, frequency, besides the distribution in all forest layers. The most important species, which increased their participation in the composition and structure were, Ocotea pulchella, Matayba elaeagnoides, Clethra scabra, Clethra uleana, Sebastiana commersoniana and Araucaria angustifolia; The species which decreased in their importância in the forest structure were, Myrsine coriacea Nectandra grandiflora Capsicodendron dinissi, Ilex theezans,Ilex dumosa and Xylosma ciliatifolium. The distribuition of the trees in the forest layers changed from increasing distribution in 1992 to uniformity in 2003, enhancing the increases in density of trees of the lower layer; the forest is in a successional process, indicated particularly by the dinamycs of the structure of the lower forest layers.

    Mary Marcondes


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

  5. [A better Brazil]. (United States)

    Lesser, Jeffrey


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

    Lins, Liliane; Carvalho, Fernando Martins


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

    Albuquerque Cristiano Queiroz de


    Full Text Available Dorsal spines (n=649 of the queen triggerfish Balistes vetula were collected between 1997 to 1999 at the central coast of Brazil and used to evaluate fish growth. The marginal increment analysis validated that 1 increment was formed annually (n=476, with minimum values observed at the summer, and coinciding with the maximum proportion of translucent growth bands. Fish's maximum fork length and age were 460 mm and 14 years respectively. The parameters of the von Bertalanffy function were: Fl∞ = 441.3 mm, K = 0.14 and T0= -1.8. Weight gain by year ranged from about 110 g yr-1 for age 5 to about 30 g yr-1 for age 14. Compared to other studies, B. vetula growth in the Central coast of Brazil was slow, which could be related to the influence of the oligotrophic water from Brazil current. Our results indicate that B. vetula's fisheries in the Central coast of Brazil until 1999 have caught mostly adult individuals over the sexual maturation lenght, 60% of them with ages from 6 to 8 yr.Entre 1997 e 1999 foram amostrados 649 espinhos de Balistes vetula na costa central do Brazil e foram utilizados para a avaliação de crescimento. A validação de anéis anuais de crescimento foi realizada através da analise de incrementos marginais, cujos valores mínimos foram observados durante o verão, coincidindo com a maior proporção de anéis translúcidos na borda do espinho. Portanto, forma-se um anel de crescimento a cada ano. A idade e o comprimento padrão máximos observados foram respectivamente 14 anos e 460 mm. Os parâmetros da equação de von-Bertalanffy foram: Fl∞ = 441,3 mm, K = 0,14 e T0= -1,8. O incremento anual em peso variou de 110 g yr-1 para a idade 5 a 30 g yr-1 para a idade 14.

  8. Brazil's mental health adventure. (United States)

    Weingarten, Richard


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

    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.

    This paper analyses the institutional model adopted for the reform of the oil industry in Brazil, beginning with the approval of Law n. 9.478 by the Brazilian Parliament in 1997. The reform of the Brazilian oil industry took place in the context of the reforms of the world's national economies throughout the 1980's and 1990's. From this worldwide process of reform stemmed a huge increase in the international capital flow directed to long-run investment opportunities in the economic infrastructure sectors. The aim of this paper is to analyse both the regulatory model for the oil and gas upstream activities in Brazil and the bidding model adopted at Brazil's National Petroleum Agency's auctions for the acquisition of exploration areas. This paper is dedicated, in its entirety, to Prof. Carmen Alveal (in memoriam), whose knowledge, support, encouragement and friendship were, for me, the most important of all, professionally and morally.

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

    augmentation of heterosexual transmission and IDUs as transmission groups, are described and analised. The geographical distribution of the AIDS cases registered between 1987-1993 in Brazil throughout the Brazilian States is evaluated by means of worksheets, maps, and non-parametric statistics. Results show that Gravimetric Centers (obtained by the use of the calculus spatial means of AIDS in Brazil are situated within a triangle the sides of which are formed lines joining the three main metropolitan areas of the wealthiest region of Brazil - the southeast, i.e. São Paulo, Rio de Janeiro and Belo Horizonte. These especially S. Paulo, function as points of attraction for these Gravimetric Centers (GCs towards the south as compared with the GCs of the general population calculated ia accordance with data from the 1980 and 1991 censuses. It is possible to observe a displacement of the GCs toward the northwest over this period in accordance with the migration patterns of the Brazilian population in general, though with a dynamic of its own. These changes in the geographical, socio-demographic and transmission group patterns show the complex nature of the epidemic in Brazil and pose additional difficulties for the development of prevention strategies.

    Patricia Filippsen Favaro


    Full Text Available Equine influenza virus (EIV (H3N8 and H7N7 is the causative agent of equine influenza, or equine flu. The H7N7 subtype has been considered to be extinct worldwide since 1980. Affected animals have respiratory symptoms that can be worsened by secondary bacterial respiratory infection, thereby leading to great economic losses in the horse-breeding industry. In Brazil, equine influenza outbreaks were first reported in 1963 and studies on hemagglutination antibodies against viral subtypes in Brazilian horses have been conducted since then. The objective of the present review was to present the history of the emergence of EIV around the world and in Brazil and the studies that have thus far been developed on EIV in Brazilian equines.

  20. Schistosomiasis control in Brazil

    Directory of Open Access Journals (Sweden)

    Katz Naftale


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

  1. Radiopharmacy education in Brazil

    Directory of Open Access Journals (Sweden)

    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.

  2. Health promotion in Brazil. (United States)

    Ivo de Carvalho, Antonio; Westphal, Marcia Faria; Pereira Lima, Vera Lucia Góes


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

    Repairing and maintenance activities on Bolivia-Brazil gas pipeline often need blow down lines. During the blow down process, the high speed of discharging gases imposes great efforts to the structures. A detailed analysis of this situation is essential for a safe operation. This paper describes two phases of a project, developed under TBG coordination. It consists in analyzing the stress and forces involved in this operation, in order to design facilities to blow down pipes and develop a safe blow down procedure for the gas pipeline. The first phase consists of a supersonic flowing simulation in the blow down gas pipeline device. The pressure behavior, mass flow and the speed at the device's ending point are calculated for different operational conditions. In the second phase, the equivalent loading caused by blow down operations is used as input in a stress analysis program to determine stress, critical sessions evaluation and material recommendations for blow down devices.

    Silva, Marcos Vinicius Miranda da [Universidade de Sao Paulo (PIPGE/USP), SP (Brazil). Programa Interunidades de Pos-Graduacao em Energia], e-mail:


    The Belo Monte hydropower plant's low generation cost is among the arguments used by Centrais Eletricas do Norte do Brazil (ELETRONORTE), a Brazilian state electric utility, to make possible its construction. This paper shows that the generation cost presented by ELETROBRAS is very low in relation to the world pattern of cost and probably unrealistic. It also shows that the generation cost cannot be used separately to determine the Belo Monte dam's economic feasibility. There is the need to include other costs, such as: socio environmental degradation and control, financial compensation for using the hydraulic resources, transmission and thermal backup stations, beyond, evidently, generation cost for assuring the credibility of the Belo Monte hydropower plant's economic analysis.

  5. Upward Lightning in Brazil (United States)

    Schumann, C.; Saba, M. M.; Alves, J.; Warner, T. A.; Albrecht, R. I.; Bie, L. L.


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

  6. Social Psychotherapy in Brazil. (United States)

    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.

  7. Heparin pharmacovigilance in Brazil. (United States)

    Junqueira, Daniela Rezende Garcia; Viana, Thércia Guedes; Peixoto, Eliane R de M; Barros, Fabiana C R de; Carvalho, Maria das Graças; Perini, Edson


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

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

  12. [Family medicine in Brazil]. (United States)

    Abath, G M


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

    The behavior of the ethanol industry in the coming years should be buoyed by several factors, among which gain prominence: feedstock, conversion technologies and products. This article aims, from the analysis of technological road maps, is dealing with Brazil in the face of the global market, is primarily addressing the international context, to assess which technologies tend to predominate, with emphasis on the ethanol industry, addressing convergent and complementary the technology road maps, especially regarding the barriers and challenges, costs and logistics, and other broader issues that govern the production of sustainable feedstock, conversion technologies and biofuels industry, with emphasis on ethanol. Conventional biofuels today are generally not competitive with fossil fuels at market prices, except for the cane ethanol already has a good performance in economic terms. Moreover, strategies for first generation ethanol differ from those for the second generation, which is at an earlier stage of technology development and still subject to comparatively high production costs. The non-economic fundamental barrier to the development of biofuels, particularly ethanol, is the uncertainty as to its sustainability. The debate sometimes on competition with food production and the potential destruction of valuable ecosystems put biofuels in the center of the discussion about sustainability. The challenges facing the ethanol industry range from the need to implement on a large scale to reduce costs along the production chain, through the need for second-generation technologies to reach the level of market, with the behavior of these factors and others will depend on each setting route.

    The aim of this work was to characterize the energy consumption related to the introduction, development, hay processing and storage of Cynodon dactylon (L.) Pers allied to the analysis of the energetic efficiency. The data used in this project were collected from EMBRAPA Gado de Leite, localized in Coronel Pacheco, Minas Gerais, Brazil. The data were obtained from a seven year period of an intensive system of milk production. Energetic coefficients were used to generate the survey and several matrix components obtained from pertinent literature. The direct energy, related to the inputs, showed more efficient participation on the energetic matrix than the indirect energy and the percentages were 94.64 and 5.31, respectively. Farm tractor was the main indirect energy consumer, which is responsible for turning on all the equipment, followed by the irrigation system. The energetic efficiency presented by the whole system was 4.2, being considered positive and demonstrating that the agriculture ecosystem is sustainable. Most of the direct energy employed in this system was oil derived on fuel form. There was, however, a great consume of another oil derived energy such as fertilizer, but mainly on the nitrogen form (28.89% of the total employed energy). (author)

    The oil industry is one of the more global sectors of the economy, with its economic agents acting and competing at the same time in many countries. The limitation of available funds for investment and competition in global scale make the host countries adapt some elements of their concession instruments, as a way to attract greater investments. The comparison of legal framework of diverse host countries is an essential part in this process of decision and an indispensable tool to help the host countries in the dispute for the attraction of international investors. Therefore, to place Brazil in this process of global competition between States is necessary the knowledge and the comparison between the conditions offered for its legal system and offered for countries considered as models of attraction of investment. This work intends to offer a comparative study of relevant legal aspects for the oil industry, amongst them: characterization of the concession instrument; reach of the participation of the state-owned company; intervention of the State in the private management. The comparison will be made between countries with different characteristics, to obtain a consolidation of paradigms that helps the evolution of the Brazilian exploration and production legal framework.

    The production chain of the oil industry encompasses production systems that operate within different ecosystems. The industry can be split into exploration, production, transportation, refining and distribution, and its importance derives from the influence it has on the nation.s economy. The aim of this study is to provide a holistic view of the different links in the oil production chain, using bibliometric indicators for technological innovation. The methodology employed to analyze the production chain took as its starting point a study of demand, i.e. a characterization of the consumers and identification of the needs and expectations of this consumer market with respect to the products supplied by the different segments of the country.s oil industry. The data was first collected through bibliographical research and a search of specialized databases on the oil production chain in Brazil and worldwide, after which it was analyzed. The result was an identification of the critical competitive factors in the chain, and a tool to assist in the management of the oil industry, to improve its competitiveness and support public and private policy-making. This article is part of a broader study, which will constitute a doctoral thesis. (author)

    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.

  20. Emergency medicine in Southern Brazil. (United States)

    Tannebaum, R D; Arnold, J L; De Negri Filho, A; Spadoni, V S


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

    Overcoming another financial crisis, the swine production has the great challenge, in this and next decades, of also reaching the sustainability in the ecosystem ambit. The Parana State/Brazil west area is known because of it's residues high production, with high pollution level, it possesses the added difficulty of presenting high concentration of animals, inserted in production centers in reduced areas. However, this situation reversion, changing the 'trouble called residue' in a 'energy source solution', by means of digesters, became a reality, with the initiative of some producers and researchers. Present work objective was to evaluate the energy production, by means of the digesters use, as alternative energy co-generation. The work was developed at a commercial farm located at the Parana State west area, with 1,700 sows, in an piglet unit producing, with production of 3,400 piglet per mouth. The studied system is constituted by two parallel digesters, with continuous flow and total capacity of 1,275 m3 per digester, with 30 days of hydraulic retention time. The generated biogas feeds a 4.1 cc engine, with six cylinders, 80 cv, 3,600 rpm, coupled to an generator, that constitutes an 50 kW electric engine. The system promoted a 58% reduction of chemical demand of oxygen. The daily gas production estimated was 208 m3, with production of electric energy of 35.2 kWh per day. For most of the year, the system has the potential of provisioning the farm of electricity for all its needs, promoting economy that is transformed into income for the activity. (author)

  3. Drought preparedness in Brazil

    Directory of Open Access Journals (Sweden)

    Ana Paula A. Gutiérrez


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

  4. Policing violence in Brazil. (United States)

    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.

  6. Evolutionary history of dog rabies in Brazil. (United States)

    Kobayashi, Yuki; Suzuki, Yoshiyuki; Itou, Takuya; Ito, Fumio H; Sakai, Takeo; Gojobori, Takashi


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

  9. All about neosporosis in Brazil. (United States)

    Cerqueira-Cézar, Camila Koutsodontis; Calero-Bernal, Rafael; Dubey, Jitender Prakash; Gennari, Solange Maria


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

    Vitória Peres de Oliveira

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

  12. Flood model for Brazil (United States)

    Palán, Ladislav; Punčochář, Petr


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

  13. Sexuality education in Brazil. (United States)

    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.

  14. Country watch: Brazil. (United States)

    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.

    The oil activities in Brazil had been started in an intensive way by the years 30 and 40. During approximately 40 years only one agent had been executed the oil activities in this country: the PETROBRAS. Many of the fields explored in the past are nowadays in decline. These fields, not interesting for the majors, would be interesting for the small and medium enterprises. The present research analyses the mature oil fields and its regulation in Brazil, looking to the 'Constituicao Federal de 1988' and to the idea of social and economic development. (author)

    utilizing the revised scale described by WIDSTROM (27. The data obtained was analised by two different ways. The grades were distributed at first in two different classes: grades 0 and 1 and grades > 2. The grades were afterwards distributed in the following two classes: grades 0 and grades > 1. The chi-square test was applied to verify which of the two types of classes adjusts better with their respective expected ratios. The results showed that when the grades were divided in the classes 0+1 and > 2 the data were more uniform within each treatment. The analysis of variance for each damage class separately, presented F values highly significant for the classes zero and zero plus one, whereas for the classes > 1 and > 2 the damage averages were very similar and the F values were not significant. The class zero plus one had F value higher and the coefficient of variation smaller than the class zero. The ZC 2451 corn compared to the variety IAC Maya XII, exibited good resistance to the corn earworm, under the field conditions of Campinas, State of São Paulo, Brazil. This resistance is of the type non preference and or antibiosis, because there was a higher percentage of ears of ZC 2451 free of earworm damage.

  1. Capital rewarding of the electric power enterprises: a comparative analysis; Remuneracao de capital das distribuidoras de energia eletrica: uma analise comparativa

    We analyze the electricity distribution segment in Brazil from 1998 to June 2005, trying to assess whether the return on capital invested was in line with the risk and opportunity cost required in the segment. We conclude that the return on capital in this segment in Brazil was systematically negative until 2003. Only in 2005 did the distribution segment really begin to recover, presenting profitability partly consistent with the estimated cost of capital. Comparisons with Argentine, Chilean and American companies reveal that firms in the latter two countries, particularly in Chile, generally managed to reward shareholders according to the opportunity cost of capital. We find evidence of differential effects of regulatory characteristics between the price-cap and cost-plus regimes in the segment's financial profitability, since the return on capital invested was more uniform and predictable in American companies, which are subject to regulation by an internal rate of return or cost-plus mechanism, than in Brazilian firms, subject to price-cap regulation. Among the groups with greater return to profitability after the rationing episode in Brazil in 2002 are EDP Brazil, CPFL Energia, Neoenergia and starting in 2004, Elektro and companies still in government hands. The EDF Group performed the worst in the study period, with negative returns from 1999 onward. (author)

  2. Brazil The Duck Lagoon (United States)


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

  7. Occupational health in Brazil. (United States)

    Bedrikow, B; Algranti, E; Buschinelli, J T; Morrone, L C


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

    Carvalho, Anna Cristina Barbosa Dias de


    Brazil impels its economy again. A development expected in 80 and 90 years it is real. This growth demands new technologies, new researches and bases that bear that growth. Electric power is in these bases, but Brazil is not ready for that. Electric power cogeneration possibility appears, using sugar cane bagasse. Alcohol and sugar plants have already that practice working with a low generation volume. With some investment this volume can be increased, adding about 10% to national energetic matrix. The aim of this work is to present a short time alternative for national electric matrix. It shows the energetic situation of the country, some experiences already implanted in some countries around the world and some options for equipment improvement used in alcohol and sugar plants. It is shown alternatives sources of electric power generation studied on Brazil, as well as the planning of National Energetic Program of ELETROBRAS. It analyses, in details, sugar cane bagasse use, which is used in Sao Paulo plants to generate electric power. Possible systems and troubles for its implantation in sugar and alcohol plants are discussed. (author)

    This document presents the legal and institutional aspects of the environmental licensing for the implementation of small hydroelectric power plants (SHPP). Laws and doctrine related to the topic were researched and concluded for Minas Gerais State with the help of a survey with the enterprises and institutions involved in the process to find out the difficulties that influence the delay of the analysis of the SHPP. It also highlights the importance of environmental zoning as a tool of environmental management for the procedure to obtain these licenses. The results show that 80% of the cases, the institutions do not respect the deadlines, 40% of the studies presented by the enterprises are insufficient, 60% there is lack of human resource and technical capacities of the environment institutions, and 80% non-fulfilment of the laws and non-integration of the institutions. Finally, the study concludes that the difficulties to obtain these licenses are based on the facts mentioned which are, the non-integration of the institutions and also, being recent, on the inexperience of the actors involved. Therefore, it is suggested that deadlines should be imposed for the institutions and the enterprises. There should be training, fund raising for the hiring of technicians, fulfillment of the law and above all, transparency in order to supply the electrical energy demand and guarantee the sustainable development.

    The Espirito Santo Basin integrates the group of basins along the eastern Brazilian continental margin. It is located between 18 deg and 21 deg S, encompassing an area of approximately 220,000 km{sup 2}, onshore and offshore the Espirito Santo State. Its geological limit with the Campos Basin to the south is defined by a Precambrian basement high (Vitoria Arch), and its northern limit with the Mucuri Basin is defined by a geopolitical limit. The study of salt tectonics processes in the Espirito Santo Basin allowed the deformational analysis and interpretation of the chronological evolution of the mini-basins developed between salt diapirs. We observe an intrinsic relationship between halokinesis and creation of subsidence troughs that may be important for trapping hydrocarbon reservoirs, and consequently form oil and gas accumulations in this portion of the basin. This geodynamics evolution of these structures is marked by a strong linkage between salt movement and coeval sedimentation in the interdomal basins, forming structures and stratigraphic traps that may constitute important aspects for the petroleum geology.

    The objective of this paper is to discuss the possible impacts on the Brazilian economy of an oil shortage crisis and its effects on the domestic market for liquid fuels. The results were obtained from simulations using a multi-sector general equilibrium model. The scenarios used in the numerical experiments were characterized by different constraining levels in imports of crude oil and oil products and also by the ability gasoline may be substituted by fuel ethanol. It is shown that the economic effects depend to a large degree on the substitution flexibility between liquid fuels. Thus it is expected that the introduction of flex-fuel vehicles in the light-duty fleet will make the Brazilian economy much less vulnerable in the event of an external oil-supply shock. (author)

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr{sup 87} / Sr{sup 86} initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle 201 refs., 130 figs., 6 tabs., 2 maps

    Recent discoveries in the Espirito Santo Basin confirm the importance of it in the national exploratory scenery (oil and gas production). The new fields like Carapo and Camarupim, beyond others, next to already known Golfinho and Canapu, totalize an addition of 560 million barrels. In this way, studies in the area add importance, as the case of the present research, where if it looked to analyze the influence of Colatina Belt in Espirito Santo Basin and secondarily in Campos Basin. The results had been gotten through the integration of diverse data, such as lineaments extracted from images SRTM, potential maps and analyze of seismic lines. It was concluded that the Colatina Belt if projects for the interior of the basins, but that the same one seems to be dislocated in relation to the direct projection of the continental features, being that its influence can be felt with bigger emphasis in the Campos Basin, while in the Espirito Santo it look like to have low importance with regard to the exploration aspects. Also it was verified the presence of numerous halo kinetic structures that affect all the mapped horizons, this element determine great importance in the generation of structural traps. (author)

    Currently there are few applications on the risk analysis procedures related to radiotherapy, mainly in the practice of brachytherapy. The objective of this study was to analyze the perception of risk levels, present in the practice of high dose rate brachytherapy (HDR), using a form based on the concept of the risk matrix and a database (SEVRRA) containing information about the processes related to routine brachytherapy. A form containing information regarding the brachytherapy procedure HDR and an attachment indicating how to complete it properly was delivered to a medical physicist of each service/institution. The reference value for the risk levels found, considered acceptable for all performed analyzes, was set at a percentage limit of 33% (assuming a failure in each 3 existing processes). The results showed that the overall risk analysis showed a value for average percentage of prioritized risk of 18% below the recommended range. About the analyzed groups, the higher average percentage of relative risk was found less than 12% of the recommended range, associated with the group of patients. On existing steps, the highest average percentage of relative risk was found less than 1% of the recommended range, associated with stage records and treatment planning. This study showed that although this procedure does not have a large history of accidents, still poses risks considerable that must be managed with great accuracy and immediate action to an effective decrease these risk percentages.

    Currently there are few applications on the risk analysis procedures related to radiation therapy, especially in the practice of radiotherapy. The objective of this study was to analyze the perception of risk levels present in the practice of teletherapy (only the use of linear accelerators), through a form based on the risk matrix concept and a database (SEVRRA) containing information about the processes related to routine teletherapy. Was delivered to a medical physicist for each service, a form containing information relating to teletherapy procedure and an annex indicating how to fill it properly. The results show that, according to the opinion of 16 medical physicists participants, six of these analyzes showed a prioritized risk percentage above 50%, other five had a risk of prioritized percentage between 0 and 50%, and the remainder had a risk percentage prioritized null. Two steps groups had the highest incidence of cases classified with high and very high risk: records and treatment planning group and equipment group. It was then possible to find the most risk processes these steps groups. Finally, we performed an analysis of the effectiveness of the controls present in the proposed form. The four most incidents controls, three of them had a percentage efficiency above 80%, and viable its continuous use in the analyzed services, as well as serving as a recommendation for use in other services not analyzed. This study showed that, although there are considerable histories of accidents for teletherapy procedure, you can not only identify the risks of higher expression but also mitigate them, based on actions and appropriate recommendations for each case analyzed properly.

    The studied area is located in the southwestern portion of Minas Gerais State, encompassing the counties of Alfenas, Areado, Machado, Poco Fundo, Campestre, Serrania, Monte Belo, Bandeira do Sul, Botelhos and Cabo Verde. This region is dominated by strongly weathered pre-cambrian rocks in association with colluvial-alluvial sediments. The present work consisted in a comparison among the mineralogical (X-Ray Diffraction), textural (Laser Granulometry), chemical (X-Ray Fluorescence) and technological (mechanical resistance, water absorption, etc, made in specimen tests) properties of the clays collected on potteries located in these counties. The mineralogical and chemical analysis displayed the kaolinitic nature of the clays from this region, showing also small amount of interlayered clays and large amount of quartz. The best results of physical analysis were obtained for clays from the counties of Cabo Verde and Monte Belo due to the presence of lower values of SiO{sub 2} (quartz) associated with a finer particle size distribution.

    Archaeological ceramics contain infinity of data about social and cultural indigenous site Caninhas/SP. The ceramics present a gradient of color (ochre to dark gray), when from the surface to the center of the piece, indicating compositional variability caused by inefficient sintering carried out by indigenous peoples. It was analyzed the composition phases by X-rays diffraction (XRD) and mapping by EDS, identifying the illite, quartz and lutecite phases (ochre region) and illite, quartz, hydrated alumina and lutecite phases (dark gray region). The results of EDS confirmed the stages identified by X-rays diffraction and suggesting the presence of roots and scrap of ceramics sintered in the composition of indigenous ceramics, when compared by optical microscope and scanning electron microscope. Vickers hardness identified as fragile and heterogeneous are archaeological ceramics, reaching approximately 203 HV in the grains of silica and 16 HV in the ceramic matrix. (author)

  5. Decentralization and REDD+ in Brazil

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available This study focuses on the analysis of high-resolution seismic profiles, integrated with sedimentological, echosounder, SRTM and satellite image datasets, of the Brazilian continental shelf adjacent to the Rio Grande do Norte State, NE Brazil. Located in the northeast of Brazil, the State of Rio Grande do Norte is bounded by two main coastal and shelf systems: the eastern coastal-shelf, from the Sagi River to the Touros High, and the northern coastal-shelf, extending from Touros High to Tibau. This shelf represents a modern, highly dynamic mixed carbonate-siliciclastic system characterized by reduced width and shallow depths as compared with other parts of the Brazilian shelf. It has an average width of 40 km, the shelf-break lying at a depth of ~ 60 m. This shelf is subject to the full strength of the westerly South Equatorial current combined with high winds and moderate to high tides and waves. A sharply defined stratigraphic boundary, probably between the Pleistocene and Holocene deposits, is clearly to be observed in the seismic record. Incised-valleys extending from the main river mouths (e.g.the Potengi, Açu, and Apodi to the shelf break dominate the area investigated and may indicate periods of lower sea level.Este estudo está direcionado ao conhecimento da plataforma continental brasileira adjacente ao Estado do Rio Grande do Norte, NE do Brasil, através da analise de perfis sismicos de alta resolução integrados a dados sedimentológicos, batimétricos, SRTM e imagens de satélites.

  19. Lateritic nickel deposits of Brazil (United States)

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


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

    Rackynelly Alves SARMENTO


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

    Penna, Maria Lucia Fernandes; Grossi, Maria Aparecida De Faria; Penna, Gerson Oliveira


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

  4. Geodiversity and geoconservation in Brazil (United States)

    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

    Soares, Lis Nunes; Silva, Ricardo Junqueira; Bernardes, Lucas Lanza; Filgueiras, Pedro Freire [V e M do Brasil S.A., Belo Horizonte, MG (Brazil)


    V and M Brazil is an integrated steel mill for the production of steel tubes. The manufacturing process includes various processes and thermal equipment, such as industrial furnaces, boilers, and others. Due to its importance, it is essential that these devices operate with the best possible efficiency. Thus, it becomes necessary to use tools and methods for performance analysis of energy processes that occurs on these devices. One tool that has been widely used in industrial environment is the exergy analysis. It is based on the Second Law of Thermodynamics, and therefore takes into account the entropy generation, indicating the maximum amount of useful energy (work) that can be drawn from a stream, with reference to environmental parameters. This paper aims to apply the exergetic methodology in industrial thermal processes that occurs at V and M Brazil, as a tool for identification of losses and potential performance improvement of energy systems to save on fuel and the reduction of environmental impacts and emissions of greenhouse gases.

    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)

  10. Brazil in the global energy world

    Energy Technology Data Exchange (ETDEWEB)

    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)

    For a performance preview of a drilling system is necessary a dynamic and integrated modeling for understanding all system forces resulting from the combination of the rock strength, cut structure action, drilling parameters, BHA and all others drilling components. This study must predict, for the drill string, vibrations and torsions, from bit to surface, its origins and its effects, and provides the best way to reduce these vibrations, determining the best bit, BHA and drilling parameters. Thereby, this study eliminates the trial and error approach and the operation risks. This paper aims to present studies of optimization for two drilling wells conducted in Brazil, one in Santos Basin and other in Campos Basin, and compares the numerical simulations results with the data from drilling operations.

    This work aims analyze the constraints to the introduction of LNG in the Brazilian energy matrix. Therefore, considers the current regulatory framework and the investments recently made by PETROBRAS to acquire LNG in the international market in order to supply power plants in the country. In order to assess the current status of the LNG plants in the electricity sector, factors are analyzed in terms of the natural gas industry and electric power industry, such as: storage, LNG contracts, operating dispatch, LNG plants pricing and operational flexibility. Despite the increase in LNG international trade and the prospect of using this product in Brazil, there are some challenges for the effective use of LNG plants by Brazilian electric sector. Some of the challenges are the need to review the methodology of calculating the cost benefit of LNG power plants. Another important challenge is to examine the use of underground storage and its influence in the operating dispatch of LNG plants. (author)

    The utilization of the biomass to generate carbonaceous materials of great application for many industrial areas is emphasized in Brazil in relation to the use of the wood focusing on great promoting of energy and carbon supply, specially for carbothermic reduction. However, the critical constraints involve the huge exploitation of native forest and the constant need of increment of the enormous areas for replanted forests. In both situations, the economic and ecological aspects have to be considered. Our country, with a potentiality of 30 per cent of the world production of sugar cane,, has a production of sugar cane bagasse around 85 million tons, which it is utilization for energy cogeneration does not exceed 75 per cent of thi total amount. This way, could be very attractive the utilization of bagasse surplus for other areas such as carbothermic reduction of quartz into silicon. Therefore, the objective of the present research, that will be an integrating part of the QITS project (Quartz Industrial Trade System) - conducted by the Laboratory of Integrated Quartz Cycle of the UNICAMP (LIQC), SP, Brazil in partner ship with UNU/IAS (The United Nations Univ./ Inst. of Advanced Studies); is to study the chemical composition of the charcoal derived from bagasse. X-ray fluorescence spectrometer was used for chemical analysis of bagasse charcoal. The charcoal samples were obtained from pyrolysis using two types of reactor: rotary drum and static thermo reactor, where bulk temperature reached 400 to 550 deg C. After this pyrolysis procedure, were carried out heat treatment temperature in the range of 750 deg C in such samples. The impurity measurements in this type of charcoal showed quartz as the majority impurity, followed by considerable amounts of others elements such as K{sub 2}O, Al{sub 2}O{sub 2}, FeO{sub 2}, according to the pyrolysis process utilized.

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

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

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

    The National Commission of Nuclear Energy (CNEN) is responsible in Brazil for the activities of licensing and control of radioactive installations in the radiotherapy medical area. The majority of these activities are developed by CNEN Co-ordination of Radioactive Installations (CORAD). One of the necessary stages for the development of licensing and control activities is the inspection of radiotherapy services (clinics and hospitals). Almost all of these inspections are carried out by CNEN Inst. of Radiation Protection and Dosimetry (IRD), through its Service of Medical Physics in Radiotherapy and Nuclear Medicine (SEFME). This work makes a survey of the main nonconformities found during ten years of inspections in radiotherapy services (1995 - 2004) and analyses the efficiency of these inspections in making the radiotherapy services develop their activities according to the norms in vigour in the country and adopt corrective actions against, at least, the nonconformities evidenced by CNEN inspectors. Additionally, it analyses the possibility of improvement and / or the optimisation of the process, through a procedure able to be unified and controlled, aiming a prompt communication to those involved in the licensing process (SEFME and CORAD) about the attendance by the radiotherapy services to the non-conformity items observed during the inspection.

    Most Brazilian constructions have low performance in terms of energy, since they received little attention (or none) concerning the energy efficiency. One of the main aspects observed is the intense use of electric energy for climatization and lighting in order to provide comfortable conditions for the dwellers. In 2009, new perspectives to change this situation emerged, due to an initiative by the Federal Government, that established the necessary regulations for energy efficiency labelling in buildings, and broadened the Brazilian Labelling Program (PBE), which, up until then, encompassed only machinery and equipment. The purpose of this article is to analyze the compliance with the new regulations for energy efficiency of constructions in the hotel sector, where small businesses are predominant, aiming at highlighting the barriers and opportunities connected to the possibilities of labeling. Hotels have been targeted for large investments, since they have become the pillars of Brazil's project to welcome tourists during the 2014 World Cup and the 2016 Olympic Games. Taking into consideration the need to develop specific methodologies for lodging possibilities, in addition to the scarce information on the use of energy in small businesses, this article is part of a series of researches carried out within the framework of the Sebrae/RJ - Procel Agreement. The outcome is a global analysis, from a business point of view, on the use of labels of energy efficiency in hotel buildings, organized upon two perspectives: the external environment (opportunities and threats) and the internal environment (strong and weak points).

  13. Numerical analysis of the fluid dynamics in a natural circulation loop; Analise numerica da dinamica do escoamento em circuitos de circulacao natural

    Energy Technology Data Exchange (ETDEWEB)

    Angelo, Gabriel


    Natural circulation loops apply to many engineering applications such as: water heating solar energy system (thermo-siphons), thermal management of electrical components (voltage converter), geothermal energy, nuclear reactors, etc. In pressurized water nuclear reactors, known as PWR's, the natural circulation loops are employed to ensure passive safety. In critical situations, the heat transfer will occur only by natural convection, without any external control or mechanical devices. This feature is desired and has been considered in modern nuclear reactor projects. This work consists of a numerical study of the natural circulation loop, located at the Instituto de Pesquisas Energeticas e Nucleares / Comissao Nacional de Energia Nuclear in Sao Paulo, Brazil, in order to establish the flow pattern in single phase conditions. The comparison of numerical results to experiments in transient condition revealed significant deviations for the Zero Equation turbulence model. Intermediate deviations for the Eddy Viscosity Turbulence Equation (EVTE), k - {omega}, SST e SSG models. And the best results are obtained by the k - {epsilon} e DES models (with better results for the k - {epsilon} model). (author)

    Bastos, Adriano Silva


    The electric sector went through deep changes along these 125 years of electrification of the country, mainly the alternation of their investment bases, hour being private for the most part, state hour. The legal bases of concession and regulation also varied in this period, trying to adapt to the effective model of the time. This work intends to analyze the evolution of the regulatory models of the electric sector, identifying the main changes of paradigms and to compare the efficiency of the models already implanted in the segment, with views to the increment of the offer of energy in the period, molding a critical profile of the best model already adopted in the national electric sector. To compare qualitatively these models requests an analysis of the investment bases a priori in the sector, identifying the contribution of resources has been private or state, following by the government's legal positioning in the sense of being only regulator, or regulator and investor, concluding with an analysis of the electric power offer in the period and the power of self-financing of the companies, in order to assent that the mixed model is the most appropriate model for the sustainable growth of the electric power generation sector in Brazil.

    Vianna Filho, Alfredo Marques


    The maintenance of systems and equipment is a central question related to Production Engineering. Although systems are not fully reliable, it is often necessary to minimize the failure occurrence likelihood. The failures occurrences can have disastrous consequences during a plane flight or operation of a nuclear power plant. The elaboration of a maintenance plan has as objective the prevention and recovery from system failures, increasing reliability and reducing the cost of unplanned shutdowns. It is also important to consider the issues related to organizations safety, especially those dealing with dangerous technologies. The objective of this thesis is to propose a method for maintenance analysis of a nuclear research reactor, using a socio-technical approach, and focused on existing conditions in Brazil. The research reactor studied belongs to the federal government and it is located in the city of Rio de Janeiro. The specific objective of this thesis is to develop the availability analysis of one of the principal systems of the research reactor, the nuclear instrumentation system. In this analysis, were taken into account not only the technical aspects of the modules related to nuclear instrumentation system, but also the human and organizational factors that could affect the availability of the nuclear instrumentation system. The results showed the influence of these factors on the availability of the nuclear instrumentation system. (author)

    Oliveira, Luiz Fernando S. de [Energy Solutions South America (Brazil); Cardoso, Cassia de O.; Storch, Rafael [Det Norske Veritas (DNV) (Brazil)


    The natural gas pipeline network grows around the world, but its operation inherently imposes a risk to the people living next to pipelines. Due to this, it is necessary to conduct a risk analysis during the environmental licensing in Brazil. Despite the risk analysis methodology is well established, some points of its application for the distribution pipelines are still under discussion. This paper presents a methodology that examines the influences of major projects and operating parameters on the risk calculation of a distribution pipeline accident in urban areas as well as the possible accident scenarios assessment complexity. The impact of some scenarios has been evaluated using a Computational Fluid Dynamics tool. The results indicate that, under certain conditions, the risks from the pipeline operation under operating pressures of 20 bar may be acceptable in location class 3 or even in class 4. These results play a very important role if management decisions on the growth of the distribution of natural gas network in densely populated areas as well as in the improvement of laws to control the activity of distribution of natural gas.

  17. Social and economic vulnerability indicators for oil exporting countries: methodology and comparison analysis; Indicadores de vulnerabilidade socioeconomica para paises exportadores de petroleo: metodologia e analise comparativa

    Energy Technology Data Exchange (ETDEWEB)

    Jesus, Fernanda Delgado de


    The oil exporting countries can be vulnerable to this row-material as the oil importing ones, due to their social economic dependence of the revenues generated by the oil and gas sector. So, it is also important for those countries the analysis of their social economic vulnerability in order to contribute for the comprehension of their real actions related to their production strategies, aiming to affect oil price and market-share. Due to that, this thesis proposes a methodology based on social economic indicators of oil exporting countries, which will enclose the following aspects: physical, productive, commercial, macro economic, fiscal and social. These indicators will be applied to the OPEC members, Norway and Mexico, and orientated through a normalized scale as in a multicriteria methodology (AHP - Analytic Hierarchy Process). The analyzed results will drive the social economic implications, and the studied countries will be classified in a scale that goes from very favorable to very unfavorable. The results point the main social economic fragilities of the oil exporting countries, designing pathways to Brazil and their possible exporting ambitions. The most important considerations that became from the vulnerable oil export countries experiences refers to the necessity to straight and increases their macro economic foundations, industrial diversification incentives and the creation of an stabilization fund (based on oil revenues) for the future generations, or to severe oil prices oscillations periods in the international market (author)

    Decision analysis applied to the development phase of petroleum fields must take into account the risk associated to many kinds of uncertainties. In the transition of the appraisal to the development phases, the importance of risk associated to the production and the recovery factor may increase significantly. The process is complex due to high investments, large number of uncertain variables and strong dependence of the results with the production strategy definition. In E and P, several decisions must be taken considering the risks involved through the appraisal of the uncertainties impact in production of petroleum fields, increase the possibility of success, measuring possible lost and sub-optimized developments identifying new opportunities. In a specific scenario, like gas production, the risk associated to the project becomes larger due to the gas prices compared to oil, the demand, the distribution's structure and the deadlines defined in contracts. The objective of this paper is to show the results of a methodology developed in a detailed study of a risk analysis process in appraisal and development phases (execution and implementation) to one of the biggest gas fields in Brazil (Mexilhao Field) and support reliable future decisions.

    There is a great global concern about the depletion and the high cost of fossil fuel reserves exploitation, more than ever, it is necessary to make a profound study and take advantage of alternative sources that can be used as energy efficiency with an appropriate pricing and low environmental impact. Brazil, which has highlighted using alternative energy sources as the use of ethanol and, in recent years, has been encouraging the expansion of its energy matrix in which the biodiesel will have a strategic importance within the agrobusiness area. Biodiesel is a fuel that can replace the diesel, which is a petroleum derivative. It is an ester, produced in the transesterification reaction of vegetable oils and animal greases, in an alcohol with an additional catalyst, are converted into fatty acids and result in esters with glycerol as sub products. The objective of this study was to estimate the final energy balance for the process biodiesel production from oil chicken waste. The energy balance estimation was quantified in calorific value according to the energy expenditure by calorimetric bomb method. The relationship between input and output of energy was around 0.97. In a first evaluation, the procedures adopted should be improved enough, so the process can become energetic and economically viable. (author)

  20. Analysis of the sum kriging and the kriging sum - a case study; Analise do problema da krigagem da soma e da soma das krigagens - estudo de caso

    Energy Technology Data Exchange (ETDEWEB)

    D' Abbadia, Martinho Romulo Iria


    This work presents some thicknesses estimates in overlapped sedimentary sections. The adopted procedure consists of the accomplishment of kriging followed by weighed corrections that provide mathematical consistency to the operation of thicknesses addition. These weighed corrections are based on the proportions between: the thicknesses of the estimated layers and the total thickness of the analyzed section; the standard deviation of the estimation error and the addition of these standard deviations; the variance of the estimation error and the addition of these variances. The proposed method is characterized by its simplicity and operational flexibility, being distinguished by: the number of intervals to be analyzed is theoretically limitless; stationary thicknesses are not required; choice of distinct neighborhoods for each analyzed interval is allowed; it has freedom for the use of distinct models in each investigated interval, making it possible to choose different functions, amplitudes and anisotropies. The technique was applied in an oil field situated in the northeast of Brazil, helping in localising the preferential depositional areas for turbiditic reservoirs and allowing inferences with respect to structural aspects of studied area.

  1. Morphological images analysis and chromosomic aberrations classification based on fuzzy logic; Analise morfologica de imagens e classificacao de aberracoes cromossomicas por meio de logica fuzzy

    Energy Technology Data Exchange (ETDEWEB)

    Souza, Leonardo Peres


    This work has implemented a methodology for automation of images analysis of chromosomes of human cells irradiated at IEA-R1 nuclear reactor (located at IPEN, Sao Paulo, Brazil), and therefore subject to morphological aberrations. This methodology intends to be a tool for helping cytogeneticists on identification, characterization and classification of chromosomal metaphasic analysis. The methodology development has included the creation of a software application based on artificial intelligence techniques using Fuzzy Logic combined with image processing techniques. The developed application was named CHRIMAN and is composed of modules that contain the methodological steps which are important requirements in order to achieve an automated analysis. The first step is the standardization of the bi-dimensional digital image acquisition procedure through coupling a simple digital camera to the ocular of the conventional metaphasic analysis microscope. Second step is related to the image treatment achieved through digital filters application; storing and organization of information obtained both from image content itself, and from selected extracted features, for further use on pattern recognition algorithms. The third step consists on characterizing, counting and classification of stored digital images and extracted features information. The accuracy in the recognition of chromosome images is 93.9%. This classification is based on classical standards obtained at Buckton [1973], and enables support to geneticist on chromosomic analysis procedure, decreasing analysis time, and creating conditions to include this method on a broader evaluation system on human cell damage due to ionizing radiation exposure.

  2. Application of activation analysis for determination of some elements in cassiterite samples; Aplicacao da analise por ativacao para a determinacao de alguns elementos em amostras de cassiterita

    Energy Technology Data Exchange (ETDEWEB)

    Armelin, Maria Jose Aguirre


    This work consists in the development of an analytical method using activation by thermal neutrons for the determination of some minor elements and traces present in cassiterite (tin ore). This method was then applied to determine these elements in samples of cassiterite from different regions of Brazil. An analysis was made of the mineralogy characteristic of cassiterite as well as of the minerals most commonly associated with it. Four main types of interference were found to occur in the analysis by activation of trace elements in samples of cassiterite. The method involves the analysis without chemical separation for the determination of some elements and the analysis with chemical separation for the determination of other elements. The steps involved in both types of analysis are described. In the analysis with chemical separation the matrix element (tin) is separated by distillation in an H{sub 2}SO{sub 4}-HBr medium, after fusion of the ore with Na{sub 2}O{sub 2}. Arsine and antimony are determined in the distilled, whereas some lanthanide elements and uranium are determined in the distillation residue by separating them as a group by precipitation with lanthanum fluoride. A discussion on the precision, accuracy and sensibility of the method is also included. (author)

  3. Municipal solid waste in Brazil: A review. (United States)

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


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

  4. [The health system of Brazil]. (United States)

    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.

  6. Women's motivation to become dentists in Brazil. (United States)

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


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

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

  8. Study and development of a risk assessment model for intra skull radiosurgery; Estudo e desenvolvimento de um modelo de analise de risco para radiocirurgia intracraniana

    Energy Technology Data Exchange (ETDEWEB)

    Teixeira, Flavia Cristina da Silva


    The reported events in radiotherapy that constitute accidents or incidents have increased worldwide in the last 25 years. Most of these events resulted from human failure and have happened in radiotherapy centers that use high technologies. The radiotherapy Quality Management needs a prospective approach through risk analysis. This approach is supported by recent publications as this actually extremely needed due the large number of accidents. Because of the complexity of the process in radiotherapy, the search for quality of care in order to ensure patient safety is one of the most discussed topics worldwide. Although only 14% of radiotherapy centers in Brazil offer treatments with intracranial radiosurgery technique (SRS), studies about the quality of care related to the safety of patients undergoing this technique is of great importance. Any deviations from the prescribed dose using SRS technique is considered more critical than in other methods of radiation treatment, as the delivered doses in SRS are higher, in the range of 10 Gy to 40 Gy, to lesions up to 50 mm in diameter, which are delivered in a single fraction or in five fractions. In view of those information, this work aims to satisfy the new Quality Management paradigm by developing a risk analysis model, and a Quality Index for SRS in Brazil, through the techniques of Process Map and FMEA used in the TG100/AAPM. The study was performed in three high technology reference radiotherapy centers, two located in Rio de Janeiro city and one in Sao Paulo city. A SRS Process Map was identified for each radiotherapy center, and then FMEA technique was applied in every subprocesses identified on the map. >From NPR values obtained by the FMEA a ranking of failure modes was held. Failure modes with NPR ≥ 100 and S ≥ 7 were chosen as priority to implement safety strategies. From the scores assigned to the S parameter in the implementation of FMEA a Severity Index (SI) and a Quality Index (QI) were created from

    Many of hydrocarbon reserves existing in the world are formed by heavy oils (deg API between 10 and 20). Moreover, several heavy oil fields are mature and, thus, offer great challenges for oil industry. Among the thermal methods used to recover these resources, steam flooding has been the main economically viable alternative. Latent heat carried by steam heats the reservoir, reducing oil viscosity and facilitating the production. This method has many variations and has been studied both theoretically and experimentally (in pilot projects and in full field applications). In order to increase oil recovery and reduce steam injection costs, the injection of alternative fluid has been used on three main ways: alternately, co-injected with steam and after steam injection interruption. The main objective of these injection systems is to reduce the amount of heat supplied to the reservoir, using cheaper fluids and maintaining the same oil production levels. In this paper, the use of N{sub 2} as an alternative fluid to the steam was investigated. The analyzed parameters were oil recoveries and net cumulative oil productions. The reservoir simulation model corresponds to an oil reservoir of 100 m x 100 m x 28 m size, on a Cartesian coordinates system (x, y and z directions). It is a semi synthetic model with some reservoir data similar to those found in Potiguar Basin, Brazil. All studied cases were done using the simulator STARS from CMG (Computer Modelling Group, version 2009.10). It was found that N{sub 2} injection after steam injection interruption achieved the highest net cumulative oil compared to others injection system. Moreover, it was observed that N2 as alternative fluid to steam did not present increase on oil recovery. (author)

    Moreira, Michel Fabio de Souza


    The solar water heating is carried through, in Brazil, by means of solar heaters compound for collectors flat plate of the type plate-and-pipes, devices that operate in stationary position and they do not require tracking of the sun. A compound collector for some formed V-trough concentrators can be an alternative to the conventional solar collectors flat plate. This compound collector for V-trough is considered, each one, for side-walls which are specularly reflecting surfaces associates in V (equivalent to a triangular gutter). Next to the vertex to each V-trough concentrators an absorber tube is fixed, for flow of the fluid to be heated. Interconnection of the absorbers tubes forms a similar tubular network existing in solar collectors of the type the plate and pipe. V-trough concentrators with the absorbers tubes are made use in series in the interior a prismatic box, which have one of its faces consisting by a glass covering and directed toward incidence of the solar radiation. An analysis of thermal performance of these devices operating stationary and without tracking of the sun is researched. A mathematical model for the computational simulation of the optical and thermal performance of these concentrative devices is elaborated, whose implementation was carried through software EES (Engineering Equation Solver). The efficiency optics of V-trough concentrators with cylindrical absorbers is calculated from the adaptation of the methodology used for Fraidenraich (1994), proposal for Hollands (1971) for V-trough cavities with plain absorbers. The thermal analysis of the considered collector was based on the applied methodology the CPC for Hsieh (1981) and Leao (1989). Relative results to the thermal performance of V-trough concentrators suggest that these configurations are not competitive, technique and economically, with the conventional plain collectors. Although some geometric configurations presented next thermal efficiencies to the conventional plain

  14. Brazil's sugarcane boom could affect regional temperatures (United States)

    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.

  16. Sources of Brazil's Counter-Hegemony

    Directory of Open Access Journals (Sweden)

    Marcos Aurelio Guedes de Oliveira


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

  17. US/Brazil joint pilot project objectives

    Energy Technology Data Exchange (ETDEWEB)



    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.

  18. Aspergillus bertholletius sp. nov. from Brazil Nuts (United States)

    Taniwaki, Marta H.; Pitt, John I.; Iamanaka, Beatriz T.; Sartori, Daniele; Copetti, Marina V.; Balajee, Arun; Fungaro, Maria Helena P.; Frisvad, Jens C.


    During a study on the mycobiota of brazil nuts (Bertholletia excelsa) in Brazil, a new Aspergillus species, A. bertholletius, was found, and is described here. A polyphasic approach was applied using morphological characters, extrolite data as well as partial β-tubulin, calmodulin and ITS sequences to characterize this taxon. A. bertholletius is represented by nineteen isolates from samples of brazil nuts at various stages of production and soil close to Bertholletia excelsa trees. The following extrolites were produced by this species: aflavinin, cyclopiazonic acid, kojic acid, tenuazonic acid and ustilaginoidin C. Phylogenetic analysis using partial β-tubulin and camodulin gene sequences showed that A. bertholletius represents a new phylogenetic clade in Aspergillus section Flavi. The type strain of A. bertholletius is CCT 7615 ( = ITAL 270/06 = IBT 29228). PMID:22952594

  2. Epidemiological Scenario of Dengue in Brazil

    Directory of Open Access Journals (Sweden)

    Rafaelle C. G. Fares


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

    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.

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

  7. The sustainability of hydropower projects in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    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.

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    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)

  14. Brazil: the children of the day after. (United States)

    O'connor, G


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

  19. Ethnozoology in Brazil: current status and perspectives

    Directory of Open Access Journals (Sweden)

    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.

    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.

    This paper analyses the economical-financial viability of a hypothetic aeolian project at the Itaparica, Bahia, Brazil. Brazil presents a great aeolian potential, particularly at the Northeastern region, where various aeolian enterprises had been implanted due to favorable conditions of the wind in that region. However, for the increasing the aeolian generation it is necessary that studies have to be done concerning to the technical viability and, specially the economical-financial viability, because the investors need reliable subsides for the decision making.

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

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

  20. Coccidia of gallinaceous meat birds in Brazil

    Directory of Open Access Journals (Sweden)

    Marcel Teixeira

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

  1. Biobanking and Privacy Law in Brazil. (United States)

    Dallari, Sueli Gandolfi; Castellaro, Felipe Angel Bocchi; Guerriero, Iara Coelho Zito


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

  3. Genetic diversity of noroviruses in Brazil

    Directory of Open Access Journals (Sweden)

    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.

  5. [Rocky Mountain spotted fever in Brazil]. (United States)

    del Sá DelFiol, Fernando; Junqueira, Fábio Miranda; da Rocha, Maria Carolina Pereira; de Toledo, Maria Inês; Filho, Silvio Barberato


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

  7. [Toxicity and apple production in southern Brazil]. (United States)

    Klanovicz, Jó


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

    Sousa, Roberta Lilian Fernandes de; Schellini, Silvana Artioli; Zornoff, Denise de Cássia Moreira; Padovani, Carlos Roberto


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

  10. Inequality and School reform in Bahia, Brazil (United States)

    Reiter, Bernd


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

    Lucas Rodriguez Forti

    Full Text Available Introduced species have the potential to become invasive and jeopardize entire ecosystems. The success of species establishing viable populations outside their original extent depends primarily on favorable climatic conditions in the invasive ranges. Species distribution modeling (SDM can thus be used to estimate potential habitat suitability for populations of invasive species. Here we review the status of six amphibian species with invasive populations in Brazil (four domestic species and two imported species. We (i modeled the current habitat suitability and future potential distribution of these six focal species, (ii reported on the disease status of Eleutherodactylus johnstonei and Phyllodytes luteolus, and (iii quantified the acoustic overlap of P. luteolus and Leptodactylus labyrinthicus with three co-occurring native species. Our models indicated that all six invasive species could potentially expand their ranges in Brazil within the next few decades. In addition, our SDMs predicted important expansions in available habitat for 2 out of 6 invasive species under future (2100 climatic conditions. We detected high acoustic niche overlap between invasive and native amphibian species, underscoring that acoustic interference might reduce mating success in local frogs. Despite the American bullfrog Lithobates catesbeianus being recognized as a potential reservoir for the frog-killing fungus Batrachochytrium dendrobatidis (Bd in Brazil, we did not detect Bd in the recently introduced population of E. johnstonei and P. luteolus in the State of São Paulo. We emphasize that the number of invasive amphibian species in Brazil is increasing exponentially, highlighting the urgent need to monitor and control these populations and decrease potential impacts on the locally biodiverse wildlife.

    Cruz, Luciane; Lima, Ana Flavia Da Silva; Graeff-Martins, Ana; Maia, Carlos Renato Moreira; Ziegelmann, Patricia; Miguel, Sandoro; Fleck, Marcelo; Polanczyk, Carisi


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

  3. SMART GRID: Evaluation and Trend in Brazil

    Directory of Open Access Journals (Sweden)

    Ricardo Moreira da Silva


    Full Text Available The Smart Grid is considered the most promising conglomerate of technology to be applied for the improvement and optimization of all power production in electrical engineer. Smart Grid's concept is being more and more recognized for its importance for representing a way to meliorate the energetic efficiency of the electric system, reducing consumption, allowing intensive use of energy generation renewable sources. Therefore, the goal of this article is to explore and present Smart Grid's concepts and its global evolution, so as perform an assessment on Smart Grid's tendencies in Brazil. In order to do this, we shown the concepts of Smart Grid, its benefits and impacts in the electric system's value chain, the barriers to its diffusion in Brazil and the paths of investments' incentives for deployment of the new technology. Accordingly, we reach the conclusion that the researches point to a long and challenging trajectory for the development and implantation of Smart Grid's technology in Brazil, which is still in a embryonic phase of pilot projects for the knowledge and technology development implantation.

  4. Hyperinflation in Brazil, Israel, and Nicaragua revisited (United States)

    Szybisz, Martín A.; Szybisz, Leszek


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

  5. [Paradoxes of health decentralization policies in Brazil]. (United States)

    Pasche, Dário Frederico; Righi, Liane Beatriz; Thomé, Henrique Inácio; Stolz, Eveline Dischkaln


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

  6. Brazil's Amazonian dams: Ecological and socioeconomic impacts (United States)

    Fearnside, P. M.


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

  7. Brazil's Market for Trading Forest Certificates. (United States)

    Soares-Filho, Britaldo; Rajão, Raoni; Merry, Frank; Rodrigues, Hermann; Davis, Juliana; Lima, Letícia; Macedo, Marcia; Coe, Michael; Carneiro, Arnaldo; Santiago, Leonardo


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

  8. Present situation of refractories in Brazil

    Energy Technology Data Exchange (ETDEWEB)

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


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

  9. Bioethics and Christian theology in Brazil. (United States)

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

  10. Heritage, sacredness and power: on different categories of historical and cultural patrimony in Brazil

    Directory of Open Access Journals (Sweden)

    Aline Sapiezinskas Krás Borges Canani

    Full Text Available This article deals with the concept of heritage present in the public policies of cultural, artistic and historical heritage preservation, aiming to widen the apprehension of the concept. Bringing examples from my fieldwork in Venezianos Lane, in Porto Alegre, my purpose in this article is to analise the attribution of values to specific buildings, objects or processes as a way to produce new meanings within the different contexts in which it occurs, observing specially the construction of signification from the point of view of familiar heritage, heritage objects seen as sacred properties and the dimension of power involved in such process. Considering the ressignifications which resulted from the heritage acknoledgement, I analise the different categories perceived by the city inhabitants who are involved with the heritage, not in a passive way, but owning the capacity to construct new significances and to give meaning to the world around them. I try to underline the symbolic dimension present in this process in which the property acquires a meaning and comes to be considered heritage.

  14. Access to Environmental Justice in Brazil

    Directory of Open Access Journals (Sweden)

    Mariana Passos Freitas


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

    Rodrigues, Thiago Oliveira [Fundacao de Tecnologia Florestal e Geoprocessamento (NUPA/FUNTEC), Brasilia, DF (Brazil). Nucleo de Projetos Ambientais


    Brazil is the world's greater producer of charcoal and most of this production takes care of to the siderurgical sector. Thus, one understands that the Brazilian steel is produced of sustainable form. However, such sustainability is not based only on a renewable energy source. The origin of the wood for the carbonization, if proceeding from planted forests or native bushes, is crucial factor in this analysis. Beyond the ambient dimension, the sustainability of the charcoal segment also is influenced by its social, economic and technological aspects. In this context, the present article searches, through the construction and the analysis of the diagnosis of the charcoal in Brazil, to evaluate the sustainability of the sector and to consider alternatives to reach it. The current model of production of charcoal in the country is unsustainable. The main adopted systems of carbonization in Brazil are low level technological with consequent decrease production. The activity is unhealthy, beyond having many cases of enslaved and infantile work. The coal of native forests is much cheaper and the fiscalization is poor, fact that discourages its production from planted forests. But if the vegetal coal will be understood as an energy solution for the siderurgical sector measures can be taken to search a model of sustainable production. (author)

  18. Danish wind power in Brazil. Part 1. The future of wind power in Brazil - market analysis

    Energy Technology Data Exchange (ETDEWEB)

    Husted Rich, N.


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

    Full Text Available Durante os anos de 1984/1985 obtiveram-se amostras sazonais para determinação de parâmetros físicos, químicos e biológicos de um lago marginal ao rio Embu-mirim, em Itapecerica da Serra, na bacia do reservatório de Guarapiranga (São Paulo, Brasil. Além de discutir os resultados obtidos quanto à flora de macrófitas aquáticas e suas relações com os outros parâmetros ambientais, são também analisados os efeitos da variação sazonal. As espécies encontradas estão presentes em diversos corpos d'água marginais, bem como ao longo do rio Embu-mirim, permitindo avaliar seu comportamento em corpos d'água semelhantes, da mesma bacia. A macrófita predominante foi Eichhornia crassipes (Mart. Solms. Os resultados obtidos demostram a tendência de uma eutrofização acelerada e o risco de macrófitas potencialmente problemáticas, como E. crassipes e Salvinia auriculata, formarem camalotes de altas densidades, que podem chegar ao reservatório de Guarapiranga, através do rio Embu-mirim, causando problemas aos diversos usos da água.In the years 1984/1985, limnological surveys were carried out at a marginal pond of the Embu-mirim river belonging to the hydrographic basin of Guarapiranga Reservoir (S.

    Full Text Available O estudo foi realizado em duas áreas no Vale do Taquari, região central do Estado do Rio Grande do Sul, Sul do Brasil. Entre agosto de 2000 e dezembro de 2001 foi realizado um estudo sobre a dieta e o uso de abrigos e marcas odoríferas por Lontra longicaudis (Olfers, 1818. Coletaram-se 275 marcas odoríferas, das quais 261 foram analisadas para determinação da dieta. O uso de marcas odoríferas ocorreu por deposição de fezes, sobretudo sobre locais conspícuos das margens dos rios ou no interior dos abrigos. Os abrigos foram formados principalmente por escavação paralela a margem dos rios. Estes abrigos foram altamente reutilizados. Ocorreu predação sobre três grupos de presas: peixes, mamíferos e insetos. Os peixes formam a base da dieta, e as famílias Loricariidae/Callichthyidae, Cichlidae, Pimelodidae/Auchenipteridae e Erythrinidae foram as mais freqüentes nas análises fecais. A ocorrência destes grupos de peixes na dieta é maior do que sua disponibilidade relativa no ambiente.The study was carried out in two areas of Taquari Valley, central region of Rio Grande do Sul State, Southern Brazil. Between August 2000 and December 2001 a study about diet and use of shelters and scent marks by Lontra longicaudis (Olfers, 1818 was performed. 275 spraints were colleted, of which 261 were analised for diet determination. The use of scent marks occured by the deposition of feaces mainly under conspicuous sites of the river margin or inside the shelters. The shelters were often formed by parallel excavation of river margin. The shelters were highly reused. Predation occurred on 3 groups of preys: Fish, Mammals and Insects. The fish, formed the diet base, and the families Loricariidae/Callichthyidae, Cichlidae, Pimelodidae/ Auchenipteridae and Erythrinidae were the most frequently identified ones in fecal analysis. The occurrence of these fish groups in the diet was higher then the relative availability in environment.

  13. Fishers' knowledge and seahorse conservation in Brazil. (United States)

    Rosa, Ierecê Ml; Alves, Rômulo Rn; Bonifácio, Kallyne M; Mourão, José S; Osório, Frederico M; Oliveira, Tacyana Pr; Nottingham, Mara C


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

    Full Text Available OBJECTIVES: To assess epidemiologic characteristics of penile cancer in Brazil. MATERIALS AND METHODS: From May 2006 to June 2007, a questionnaire was distributed to all Brazilian urologists. Their patients' clinical and epidemiological data was analyzed (age, race, place of residence, history of sexually transmitted diseases, tobacco smoking, performance of circumcision, type of hospital service, as well as the time between the appearance of the symptoms and the diagnosis, the pathological characteristics of the tumor (histological type, degree, localization and size of lesion, stage of disease, the type of treatment performed and the present state of the patient. RESULTS: 283 new cases of penile cancer in Brazil were recorded. The majority of these cases occurred in the north and northeast (53.02% and southeast (45.54% regions. The majority of patients (224, or 78.96% were more than 46 years of age while only 21 patients (7.41% were less than 35 years of age. Of the 283 patients presenting penile cancer, 171 (60.42% had phimosis with the consequent impossibility to expose the glans. A prior medical history positive for HPV infection was reported in 18 of the 283 cases (6.36%. In 101 patients (35.68% tobacco smoking was reported. The vast majority of the cases (n = 207; 73.14% presented with tumors localized in the glans and prepuce. In 48 cases (16.96% the tumor affected the glans, the prepuce and the corpus penis; in 28 cases (9.89% the tumor affected the entire penis. The majority of the patients (n = 123; 75.26% presented with T1 or T2; only 9 patients (3.18% presented with T4 disease. CONCLUSION: Penile cancer is a very frequent pathology in Brazil, predominantly affecting low income, white, uncircumcised patients, living in the north and northeast regions of the country.

    Mylène Gaulard


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

    Full Text Available In this paper, I seek to assess the role of the media in ongoing subnational democratization processes from a State-in-society perspective. I use the case of Bahia, a state in North-Eastern Brazil, to assess ownership and social access to the media, the media’s autonomy from both the State and social actors as well as how conflicts between public interest and private profit are solved. We will thus understand the role of subnational media in sustaining pluralism and in providing independent sources of information, two critical dimensions of democracy.

  2. Catholic populism and education in Brazil (United States)

    Paiva, Vanilda


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

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

    Quirk, David G.; Nielsen, Malene; Raven, Madeleine [Maersk Oil and Gas, Copenhagen (Denmark); Menezes, Paulo [Maersk Oil and Gas, Rio de Janeiro, RJ (Brazil)


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

  6. Selective abortion in Brazil: the anencephaly case. (United States)

    Diniz, Debora


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

  7. Analysis of medicine advertisement produced in Brazil. (United States)

    Wzorek, Lorilei de Fátima; Correr, Cassyano J; Badaró Trindade, Angela C; Pontarolo, Roberto


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

  8. Coccidioidomycosis in Brazil. A case report

    Directory of Open Access Journals (Sweden)

    MARTINS Marilena dos Anjos


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

  9. Bullying during adolescence in Brazil: an overview. (United States)

    Pigozi, Pamela Lamarca; Machado, Ana Lúcia


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

  10. Forensic entomology and main challenges in Brazil. (United States)

    Gomes, Leonardo; Von Zuben, Cláudio J


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

  12. Climatology of destructive hailstorms in Brazil (United States)

    Martins, Jorge A.; Brand, Veronika S.; Capucim, Mauricio N.; Felix, Rafael R.; Martins, Leila D.; Freitas, Edmilson D.; Gonçalves, Fabio L. T.; Hallak, Ricardo; Dias, Maria A. F. Silva; Cecil, Daniel J.


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

  13. The changing face of autism in Brazil. (United States)

    Rios, Clarice; Costa Andrada, Barbara


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

  14. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

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

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

  16. Status of food irradiation in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    Kikuchi, O.K. [Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, SP (Brazil)


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

  17. Pediatric allergy and immunology in Brazil. (United States)

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

  18. Cryptococcosis outbreak in psittacine birds in Brazil. (United States)

    Raso, T F; Werther, K; Miranda, E T; Mendes-Giannini, M J S


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

  19. Epidemiological aspects of strongyloidiasis in Brazil. (United States)

    Paula, F M; Costa-Cruz, J M


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

  20. Health promotion in school environment in Brazil (United States)

    Horta, Rogério Lessa; Andersen, Cristine Scattolin; Pinto, Raquel Oliveira; Horta, Bernardo Lessa; Oliveira-Campos, Maryane; de Andreazzi, Marco Antonio Ratzsch; Malta, Deborah Carvalho


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

  1. [Retrospect of tuberculosis control in Brazil]. (United States)

    Hijjar, Miguel Aiub; Gerhardt, Germano; Teixeira, Gilmário M; Procópio, Maria José


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

  2. Implementation of thermographers' certification in Brazil (United States)

    dos Santos, Laerte; Alves, Luiz M.; da Costa Bortoni, Edson


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

  3. Paragonimiasis: first case reported in Brazil

    Directory of Open Access Journals (Sweden)

    Antônio Carlos Moreira Lemos

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

  6. Observed Low Frequency Variability of the Brazil Current Front (United States)

    Goni, G. J.; Bringas Gutierrez, F.; Di Nezio, P. N.


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

  7. Nephrology in Latin America, with special emphasis on Brazil. (United States)

    Zatz, Roberto; Romão, J E; Noronha, I L


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

  8. Case studies in international tobacco surveillance: cigarette smuggling in Brazil. (United States)

    Shafey, O; Cokkinides, V; Cavalcante, T M; Teixeira, M; Vianna, C; Thun, M


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

    An analysis of the institutional evolution of the governmental organizations which were responsible for the regulation of the electrical energy sector in Brazil (before the establishment of the ANEEL) is presented . Taking into account the various levels of subordination and independence in their actuation, the different missions and powers given to these agencies regarding the inspection, controlling, planning and regulating the industry, are compared and discussed. The conducted analysis is essentially formal, based on the legal instruments which defined and established the creation of those agencies. (author)

  11. Pediatric Hospital: The Paradigms of Play in Brazil. (United States)

    de Macedo, Lino; da Silva, Gláucia Faria; Setúbal, Sandra Mutarelli


    The role of play in Brazilian children's hospitals is highlighted, as well as the perspective of humanization in Brazil. Some aspects of our culture are crucial to understanding the importance of play considering our society. Sabara Children's Hospital ("Hospital Infantil Sabará") in Brazil is used particularly to discuss humanization. To understand the issue of play in Brazil, it is important to discuss hospitals in their social context, their history, current roles in children's care, humanization history and child development, according to the approaches of Piaget and Winnicott that are used in our culture.

  12. Property Rights, Land Conflict and Tenancy in Brazil


    Lee J. Alston; Bernardo Mueller


    Tenancy has been a means for labor to advance their socio-economic condition in agriculture yet in Brazil and Latin America, tenancy rates are low compared to the U.S. and the OECD countries. We test for the importance of insecure property rights in Brazil on the reluctance of landowners to rent because of a fear of expropriation arising from land reform. Since 1964, the Land Statute in Brazil has targeted rental lands for redistribution. The expropriation of farms, resulting from land confli...

    Full Text Available This article raises the question of whether recently implemented legislation in Colombia and Brazil (1 provides the necessary tools to prevent the harms of wildlife trafficking (WLT and (2 influences humans’ practices concerning the use of nonhuman animals. These questions are investigated from the dual perspectives of green criminology and public policy. The analysis is based on a qualitative empirical study undertaken in Colombia and Brazil whereby we discuss the function of the legislation in Colombia and Brazil in preventing illegal WLT. We consider the legitimacy of different practices of WLT and evaluate them with respect to species justice and environmental justice.

  15. An institutional approach to the history of wine in brazil


    Cavalcante Carolina Miranda


    The history of wine in Brazil dates back to 1532, when Brás Cubas tried to cultivate the vine on São Paulo coast. As we can imagine, it was not a very successful venture. Later, other efforts were made by Jesuits in the seventeenth century. In 1739 Portugal prohibited the production of grapes and wine in the colony and this prohibition lasted until the Independence of Brazil in 1822. Although it is interesting to mention those fledgling efforts to produce wine in Brazil, the decisive impetus ...

  16. Listeriosis in the far South of Brazil: neglected infection?

    Directory of Open Access Journals (Sweden)

    Dulcinea Blum-Menezes


    Full Text Available Listeriosis is an under-diagnosed and under-reported infection; however, listeriosis is not a compulsorily notifiable disease in Brazil. We provide an overview of the rates of listeriosis in the United States of America (USA, Europe, Latin America, and Brazil during the past decade. We also report a case of miscarriage caused by listeriosis in which there was no suspicion of this infection. This overview and the case we report serve as reminders of the often-neglected threat of listeriosis and its potential to cause miscarriage while highlighting the necessity of recognizing listeriosis as a compulsorily notifiable disease in Brazil.

  18. Market Behavior for in Shell Brazil Nuts Produced in Brazil from 2000 to 2010

    Directory of Open Access Journals (Sweden)

    Elisangela Lobo Schirigatti

    Full Text Available ABSTRACT This paper aimed to analyze the market behavior of in shell Brazil nuts produced by Brazil during the period of 2000 to 2010. In order to do it, structural brakes in the data were identified, the existence of correlations between the variables price, quantity and value was investigated; and the shift of the supply and demand curves was described for the nuts production. The trend model was used to identify the direction of the shift, by calculating the growth rates of national prices and of produced quantities. When analyzing the whole period (2000-2010, there was a positive shift of the demand curve, but when separately analyzing the two sub periods defined by the Chow test (2000-2005 and 2006-2010, a negative shift of the supply curve was identified on the first sub period, while the second subperiod revealed a positive shift of the supply curve. The results showed that the market of Brazil nuts is ascending and that the government’s incentive policies to the activity were effective.

  19. Telemedicine: challenges to dissemination in Brazil

    Directory of Open Access Journals (Sweden)

    Jose Manuel Santos de Varge Maldonado

    Full Text Available Abstract: Telemedicine has been seen as an important tool for facing the challenges of universal health systems. The goal of this article is to discuss the main challenges to its full dissemination in Brazil. Being a somewhat new area, there are not many scientific papers that systematize it. This article is an exploratory paper, as it aims to provide an overall perspective on the subject. From an economic point of view, telemedicine is a strategic area due to its an intrinsic potential of being a source for generating innovation, for requiring and incorporating technological breakthroughs from other areas, and for its interdisciplinary nature and dynamic inter-relations that drive different industries. From the social perspective, it has the potential to make access to health services democratic, by connecting remote regions with health services located in hospitals and centers of reference for prevention, diagnosis and treatment.

    Luciana Contreira Domingo


    Full Text Available Delineate the Spanish teaching trajectory in the Brazilian educational system is, if not hard, a surprising task. In this job we will reflect about the Spanish language trajectory in Brazil. To try to understand the way how the Brazilian educative system  understands the Spanish teaching in our territory, will be analyzed the movements to offer this language at the Brazilian basic education and some of the main actions carried out until the moment. To map the way, we will focus in four moments between 1942 until the present.  Our reflection shows that, in spite of the incentive realized in the elaboration of a Spanish insertion in the Brazilian educational system proposal, we didn’t build a solid linguistic policy which attends to the teaching specificities in our country.

  1. Democratization and Transitional Justice in Brazil

    Directory of Open Access Journals (Sweden)



    Full Text Available Brazil experienced a long process of political transition featured by an intense game of political and social forces, in which different actors with different democratization projects clashed. Despite the leadership of the transition process have been in the hands of conservative elites linked to the military dictatorship, broad sectors of the oposition and of the lefts, as well as representants of social movements, disputed the transitional space and expanded the initial design of the regime. This long transition —marked by negotiations, frustrations and resilience— reflected on the transitional justice model adopted by the country. Almost 30 years after the end of military dictatorship, the Truth Commission established by President Dilma Rousseff in 2012, drew attention to issues related to memory, justice and reparation and showed that the democratization process, in some respects, is still incloncluded. This article aims to restore this historical process highlighting some of its characteristics and specificities.

  2. Peregrino : a heavy oil development offshore Brazil

    Energy Technology Data Exchange (ETDEWEB)

    Eliassen, H. [StatoilHydro, Trondheim (Norway)


    This paper discussed a commercial development plan for an offshore oil field located off the coast of Brazil. A 3-D reservoir flow model was combined with an integrated production system model in order to model water-flooding and water injection strategies as well as to determine optimal water handling capacity. Flow assurance modelling was also conducted. A 3-D geological model was developed using data from wells drilled on the field as well as data from a regional sedimentological model. Reservoir penetration will be approximately 40,500 meters. Multilateral wells will be used to increase reservoir penetration in the future. The first phase of the development will consist of a floating production, storage and offloading unit as well as 2 wellhead platforms. A combined power and heating system will be used to provide power for pumps and to heat water. It was concluded that a high recovery factor is needed to ensure the economic viability of the project. 5 figs.

  3. Astronomy Outreach In Parana state/Brazil (United States)

    Emilio, Marcelo


    Paraná is a state at South of Brazil with a population of 11 million people. There are two planetarium and two fixed observatories devoted to Astronomy outreach. The great majority of population have no access to information and knowledge of astronomy discoveries. Another problem is the teaching formation of astronomy studies. In this work we relate an initiative that started at the International Year of Astronomy in 2009 that involved Universities and amateur groups that is still in place. After several grants from the Brazilian National Council for Scientific and Technological Development and Araucária Foundation we were able to reach more than 100.000 people with a mobile planetarium and night astronomic observations. We also providde one-week classes to more than 1.000 teachers in several cities of the state.

  4. Origin of emerald deposits of Brazil (United States)

    Giuliani, G.; Silva, L. J. H. D.; Couto, P.


    Precambrian emerald deposits of Brazil are found in a typical geologic setting with Archean basement and supracrustal, ultramafic, granitoid and rocks. Volcano-sedimentary series occur as imbricated structures or as bodies affected by complex folding and deformation. Emerald mineralization belongs to the classic biotite-schist deposit, which formed by the reaction of pegmatitic veins within ultrabasic rocks. At the same time, pegmatite-free emerald deposits linked to ductile shear zones are also known. Emerald formation is attributed to infiltrational metasomatic processes provoking a K-metasomatism of the ultrabasic rocks and also a desilication of the pegmatites. A new classification based on the geological setting, structural features, and ore paragenesis is proposed.

  5. Literacy in Brazil: from Rights to Reality (United States)

    Ireland, Timothy D.


    At a time when some 24% of the Brazilian population of 182 million are functionally illiterate, the author shows how illiteracy is concentrated in traditionally poor and disadvantaged social and ethnic groups as well as in certain regions of the country. He surveys the changes in legislation, policies and attitudes relating to literacy over the past few decades and describes how literacy is increasingly seen as a continuous process rather than a short-term, low-cost intervention. While there is still a lack of a broad, coordinated policy and adequate funding in this area, and while the challenges remain formidable, the author concludes that Brazil is moving slowly in the right direction.

  6. Diptera, Drosophilidae: historical occurrence in Brazil

    Directory of Open Access Journals (Sweden)

    Valente, V. L. S.


    Full Text Available This study presents a literature review of Drosophilidae (Diptera species occurrence in Brazil. The number of speciesrecorded is 304, with Drosophila being the genus with the greatest number of species, followed by Zygothrica,Hirtodrosophila and Diathoneura, which belong to the Drosophilinae subfamily. Drosophila was shown to be the mostinvestigated taxon in the family, with the best resolved species distribution. The low number of records of species fromother genera indicates the paucity of studies specifically designed to investigate these species. Records of species forsome regions of the country like the north and northeast, as well as for some biomes like Caatinga, Pantanal and thePampas, are likewise rare. Apart from the banana bait, different collection methods may be necessary, like thecollection at other oviposition resources, the use of baits other than fermenting fruit, and the adoption of samplingapproaches that do not use baits.

  7. Tropical spastic paraparesis in Northeastern Brazil

    Directory of Open Access Journals (Sweden)

    C. M. de Castro Costa


    Full Text Available Ten possible cases of tropical spastic paraparesis (TSP in Northeastern Brazil (Ceará are presented. They show the typical symptoms and signs of TSP consisting of weakness of the lower limbs, spastic gait, hiperreflexia, bladder dysfunction and variable signs of posterior columns impairment. The laboratory examinations excluded other compressive, infective, degenerative or demyelinating lesions of their spinal cord. Our patients age ranged from 21 to 59 years, all were of black origin and all were of lower social class. There was a slight preponderance of females. An etiological implication of a retrovirus (HTLV-I has been shown for TSP, but for lack of technical conditions we could not determine it in our patients, and that stands as our subsequent step in those and further cases.

  8. The challenges of ageism in Brazil (United States)

    Goldani, Ana Maria


    The material and symbolic resource flows and obligations between generations leave an indelible imprint on family members. These intergenerational exchanges have increased in recent years with growing human longevity and they thus have become important to current academic and policy agendas. Concurrently, ageism and age discrimination have emerged as important subjects. The main goal of this article is to call attention to these issues and their relationship with the current policy debate on resource allocation by age groups. We argue that ageism and the practice of age discrimination in Brazil should be viewed as part of the multiple forms of discrimination experienced by individuals. While noticing someone’s age is not inherently offensive, acting on age-based stereotypes clearly works against the individual and often goes unchallenged by mainstream society. A central assumption in this paper is that the way we frame ageism and intergenerational relations significantly affects perceived age discrimination and support for age-based social programs.

    The Brazilian cement industry produced 64 million tons of cement in 2012, with noteworthy contribution of CP-II (slag), CP-III (blast furnace) and CP-IV (pozzolanic) cements. The industrial pole comprises about 80 factories that utilize raw materials of different origins and chemical compositions that require enhanced analytical technologies to optimize production in order to gain space in the growing consumer market in Brazil. This paper assesses the sensitivity of mineralogical analysis by X-ray diffraction associated with cluster analysis to distinguish different kinds of cements with different additions. This technique can be applied, for example, in the prospection of different types of limestone (calcitic, dolomitic and siliceous) as well as in the qualification of different clinkers. The cluster analysis does not require any specific knowledge of the mineralogical composition of the diffractograms to be clustered; rather, it is based on their similarity. The materials tested for addition have different origins: fly ashes from different power stations from South Brazil and slag from different steel plants in the Southeast. Cement with different additions of limestone and white Portland cement were also used. The Rietveld method of qualitative and quantitative analysis was used for measuring the results generated by the cluster analysis technique. (author)

    The Bolivia-Brazil Natural Gas Pipeline with 2,600 kilometers of extension from Rio Grande City in Bolivia down to Canoas City, in Brazil s south. The pipeline crosses quite a few types of geological fields and topography. The pipeline's south section is quite interesting due of its bumpy topography combined with a variety of geological materials, such as, colluviums deposits and landslide areas. Curriola River at kilometer 408 of the pipeline, east region of Parana's State, crosses inclination slopes as steeply as 40 degrees. A superficial drainage system was built in order to prevent soil's motions. Every year, during the rainy season, that system was incapable of a properly drainage, generating tension cracks mainly because the embankment is more than 6 meters high. This paper's goal is to present a historical case including some site characterization, with all the mechanical investigation made, including mechanical stresses status, residual stresses assessment and a total combined stress decompose attempt into its components and how they were used to support the studies for the slope stabilization and gas pipeline integrity.

    Lourenco, Manuel Jacinto Martins


    Eleven institutions of education and research in Brazil use particle accelerators, which fulfill different functions and activities. Currently, these institutions employ a total of fifteen accelerators. In this paper, the object of study is the radiological protection of occupationally exposed individuals, the general public and the radiation safety of particle accelerators. Research facilities with accelerators are classified in categories I and II according to the International Atomic Energy Agency or groups IX and X in accordance with the Brazilian National Commission of Nuclear Energy. Of the 15 accelerators in use for research in Brazil, four belong to category I or group X and eleven belong to category II or group IX. The methodology presented and developed in this work was made through the inspection and assessment of safety and radiological protection of thirteen particle accelerators facilities, and its main purpose was to promote safer use of this practice by following established guidelines for safety and radiological protection. The results presented in this work showed the need to create a program, in our country, for the control of safety and radiological protection of this ionizing radiation practice. (author)

    As a further stage of the new oil and gas industry in Brazil, various challenges are now faced as an outcome from the O and G projects progress, under the legal framework in force in Brazil. Among all are the first unitization processes, which require a set of steps to be performed in order to achieve a unitization agreement. The paper aims at analyzing the legal, technical and drafting issues to be dealt with in such agreements. After a brief introduction to the general issues at stake in the unitization agreements the study shall encompass a follow up of the sequence of events to be complied with. One could mention the settlement of the criteria onto calculations to serve as guidelines for the negotiations will be based on. That, is usually based on concepts as oil in place, possible O and G in the reservoir, or reserve, which must be agreed by all involved parties. Another possible step to be considered is the creation of a common database, in order to permit fast decisions and optimise E and P operations in the unitized area. Other concerns should be addressed, depending on the amount of O and G to be produced from the unitized area, as: the avoidance of multiple redeterminations aiming to decrease unnecessary expenditures, which could jeopardize the arising project profitability; and the recalculations of Government take, royalties and other incumbencies, to be shared by all involved parties. The paper shall also mention the experience of other countries trying to adopt, where applicable and compatible with the best practices of the oil industry, solutions adopted where tradition in oil and gas is more mature. It should be considered that, in each bidding round the Brazilian Concession Agreement has undergone changes, therefore during an unitization process with two different versions of the Concession Agreement differences between corresponding clauses will have to be faced. Comments should also be made about satellite agreements, encompassing O and G buying

  13. Transferring ART research into education in Brazil. (United States)

    Navarro, Maria Fidela de Lima; Modena, Karin Cristina da Silva; Freitas, Maria Cristina Carvalho de Almendra; Fagundes, Ticiane Cestari


    The aim of this study was to evaluate the teaching of the Atraumatic Restorative Treatment (ART) approach in Brazilian dental schools. A questionnaire on this subject was sent to Pediatric Dentistry, Operative Dentistry and Public Health Dentistry professors. The questions approached the following subjects: the method used to teach ART, the time spent on its teaching, under which discipline it is taught, for how many years ART has been taught and its effect on the DMFT index. A total of 70 out of 202 dental schools returned the questionnaire. The ART approach is taught in the majority of the Brazilian dental schools (96.3%), and in most of these schools it is taught both in theory and in clinical practice (62.9%). The majority (35.3%) of professors teach ART for 8 hours, and most often as part of the Pediatric Dentistry discipline (67.6%). It has been taught for the last 7 to 10 years in 34.3% of dental schools. Most professors did not observe a change in the DMFT index with this approach. There is a diversity in the teaching of ART in Brazil in terms of the number of hours spent, the teaching method (theory and practice), and the disciplines involved in its teaching. It is necessary to address the training of professors in the ART approach for the whole country. An educational model is proposed whereby a standard ART module features as part of other preventive and restorative caries care educational modules. This will facilitate and standardize the introduction and adoption of the ART approach in undergraduate education in Brazil.

  14. The burden of injury in Brazil, 2003

    Directory of Open Access Journals (Sweden)

    Vilma Pinheiro Gawryszewski

    Full Text Available CONTEXT AND OBJECTIVE: Since 1980, injuries have been the second biggest cause of death among the Brazilian population. This study aimed to analyze national data on fatal injuries and nonfatal injury hospitalization in Brazil, for 2003. DESIGN AND SETTING: This was a population-based descriptive study, Brazil, 2003. METHODS: Data from 126,520 fatal injuries and 733,712 nonfatal injuries seen at public hospitals were analyzed. The data were stratified by sex, age, intent and injury mechanism. Raw and age- and sex-specific rates were calculated per 100,000 individuals. RESULTS: The raw injury mortality rate was 71.5/100,000 (122.6/100,000 for male and 22.0/100,000 for female. For fatal injuries, the proportions of unintentional and intentional injuries were equal (44.3% and 46.9%, respectively. Homicides were the leading cause, 40.3% overall (28.8/100,000, followed by transport-related deaths, 26.2% overall (17.0/100,000. For nonfatal injuries, the rate was 414.8/100,000 and unintentional injuries were predominant (88.9%. Overall, the leading cause was unintentional falls, accounting for 42.6% of victims treated in public hospitals (176.8/100,000. Transport-related injuries were second: 15.0% overall; 62.0/100,000. Fractures comprised 46.7% of principal diagnoses at hospitals. The injury types in the fatal and nonfatal datasets varied according to sex and age. The highest rates were found among young males and elderly people. CONCLUSIONS: Injury prevention activities need to be developed. To prevent deaths, homicide has to be addressed. Among hospitalized cases, falls are the most important problem. Traffic-related injuries play an important role in morbidity and mortality.

    Zika virus (ZIKV) is a flavivirus that is responsible for the current epidemic in Brazil and the Americas. ZIKV has been causally associated with fetal microcephaly, intrauterine growth restriction, and other birth defects in both humans and mice. The rapid development of a safe and effective ZIKV vaccine is a global health priority, but very little is currently known about ZIKV immunology and mechanisms of immune protection. Here we show that a single immunization with a plasmid DNA vaccine or a purified inactivated virus vaccine provides complete protection in susceptible mice against challenge with a strain of ZIKV involved in the outbreak in northeast Brazil. This ZIKV strain has recently been shown to cross the placenta and to induce fetal microcephaly and other congenital malformations in mice. We produced DNA vaccines expressing ZIKV pre-membrane and envelope (prM-Env), as well as a series of deletion mutants. The prM-Env DNA vaccine, but not the deletion mutants, afforded complete protection against ZIKV, as measured by absence of detectable viraemia following challenge, and protective efficacy correlated with Env-specific antibody titers. Adoptive transfer of purified IgG from vaccinated mice conferred passive protection, and depletion of CD4 and CD8 T lymphocytes in vaccinated mice did not abrogate this protection. These data demonstrate that protection against ZIKV challenge can be achieved by single-shot subunit and inactivated virus vaccines in mice and that Env-specific antibody titers represent key immunologic correlates of protection. Our findings suggest that the development of a ZIKV vaccine for humans is likely to be achievable.

  16. Solar energy for steam generation in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    De Carvalho, A.V. Jr.; Orlando, A. DeF.; Magnoli, D.


    Steam generation is a solar energy application that has not been frequently studied in Brazil, even though for example, about 10% of the national primary energy demand is utilized for processing heat generation in the range of 100 to 125/sup 0/C. On the other hand, substitution of automotive gasoline by ethanol, for instance, has received much greater attention even though primary energy demand for process heat generation in the range of 100 to 125/sup 0/C is of the same order of magnitude than for total automotive gasoline production. Generation of low-temperature steam is analyzed in this article using distributed systems of solar collectors. Main results of daily performance simulation of single flat-plate collectors and concentrating collectors are presented for 20/sup 0/S latitude, equinox, in clear days. Flat plate collectors considered are of the aluminum roll-bond absorber type, selective surface single or double glazing. Considering feedwater at 20/sup 0/C, saturated steam at 120/sup 0/C and an annual solar utilization factor of 50%, a total collector area of about 3,000 m/sup 2/ is necessary for the 10 ton/day plant, without energy storage. A fuel-oil back-up system is employed to complement the solar steam production, when necessary. Preliminary economic evaluation indicates that, although the case-study shows today a long payback period relative to subsidized fuel oil in the domestic market (over 20 years in the city of Rio de Janeiro), solar steam systems may be feasible in the medium term due to projected increase of fuel oil price in Brazil.

There is a diversity in the teaching of ART in Brazil in terms of the number of hours spent, the teaching method (theory and practice, and the disciplines involved in its teaching. CONCLUSIONS: It is necessary to address the training of professors in the ART approach for the whole country. An educational model is proposed whereby a standard ART module features as part of other preventive and restorative caries care educational modules. This will facilitate and standardize the introduction and adoption of the ART approach in undergraduate education in Brazil.

  7. Phillips curve in Brazil: an unobserved components approach

    Directory of Open Access Journals (Sweden)

    Vicente da Gama Machado


    Full Text Available This paper estimates reduced-form Phillips curves for Brazil with a framework of time series with unobserved components, in the spirit of Harvey (2011. However, we allow for expectations to play a key role using data from the Central Bank of Brazil's Focus survey. Besides GDP, we also use industrial capacity utilization rate and IBC-Br index, as measures of economic activity. Our findings support the view that Brazilian inflation targeting has been successful in reducing the variance of both the seasonality and level of the inflation rate, at least until the beginning of the subprime crisis. Furthermore, inflation in Brazil seems to have responded gradually less to measures of economic activity in recent years. This provides some evidence of a flattening of the Phillips curve in Brazil, a trend previously shown by recent studies for other countries.

    Type 2 diabetes mellitus currently ranks high among indicators used in Global Burden of Disease Studies. The current study estimated the burden of disease attributable to type 2 diabetes mellitus and its chronic complications in Brazil, 2008. We calculated disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) stratified by gender, age bracket, and major geographic region. Type 2 diabetes mellitus accounted for 5% of the burden of disease in Brazil, ranking 3rd in women and 6th in men in the composition of DALYs. The largest share of DALYs was concentrated in the 30-59-year age bracket and consisted mainly of YLDs. The highest YLL and YLD rates were in the Northeast and South of Brazil, respectively. Chronic complications represented 80% of YLDs from type 2 diabetes mellitus. Type 2 diabetes mellitus ranked as a leading health problem in Brazil in 2008, accounting for relevant shares of mortality and morbidity.

  10. Nuclear safeguards in Brazil and Argentina: 25 years of ABACC (United States)

    Kassenova, Togzhan


    As possessors of advanced nuclear technology, Brazil and Argentina bear special responsibility for helping the international community and neighbors in their region feel confident that their nuclear programs are peaceful, secure, and safe. Over the past 25 years, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) has played an indispensable role in strengthening such confidence by implementing nuclear safeguards in the two countries. Today, ABACC carries out safeguards inspections at a total of 76 nuclear facilities in Brazil and Argentina. This article describes how Brazil and Argentina view trends in the global nonproliferation regime and international nuclear safeguards, and explains how these trends relate to unique challenges and opportunities facing Brazil, Argentina, and ABACC.

  15. Foreign policy of the New Left: explaining Brazil's Southern partnerships

    Directory of Open Access Journals (Sweden)

    Megan Pickup


    Full Text Available Abstract The purpose of this study is to consider the relationship between domestic change and foreign policy in Brazil, a country seeking to become Latin America's hegemon, and achieve greater global status. It focuses on Brazil's partnerships with other countries in the Global South. It argues that, due to the combination of institutions and interests behind foreign policy-making in Brazil, there is no coherent project of South-South engagement. As a result, South-South ties tend to contradict the Brazilian government's foreign policy objective of acting as a global equaliser. The study also examines the drivers of Brazil's foreign conduct, and argues that the politico-economic determinants of foreign policy differ from those of domestic policy.

    de Jesus, Lisieux Eyer; Aguiar, Alexandre Santos; de Campos, Maria do Socorro Mendonça; Baratella, José Roberto de Sousa; Ketzer, João Carlos; Mastroti, Roberto Antônio; Amarante, Antônio Carlos M


    To define the distribution of Pediatric Surgeons in Brazil and the distribution of job offered for specialists in the country. To compare the professional profile of Brazilian Pediatric Surgeons with other countries. Statistical data derived from Brazilian Institute of Geography and Statistics (IBGE), Brazilian Medical Council (CFM) and Brazilian Society of Pediatric Surgery (CIPE) were used to define the professional profile of pediatric surgeons in Brazil. Eight-hundred-and-five pediatric surgeons are needed in Brazil only to treat neonates and toddlers. Professionals are excessively concentrated in South and Southeast and insufficient numbers are found in North and Northeast. Data about the number of pediatric surgeons working in Brazil are conflicting: data obtained from FIOCRUZ differ from those from CFM and CIPE. The working routine of Brazilian pediatric surgeons is different from that of North-American and European specialists, from where the major part of our references is extracted. Brazil needs a minimum of 805 pediatric surgeons working full time only to treat nenonates and toddlers. Specialists are not well distributed throughout the country. The southeast is a training center and exports specialists to the rest of the country. Epidemiological data concerning the distribution of professionals in Brazil are conflicting.

  10. Scanning insights on sustainability and supply chain management in Brazil

    Directory of Open Access Journals (Sweden)

    Minelle E. Silva


    Full Text Available This paper aims to analyse how the publications in Brazil are considering the relationship between sustainability and supply chain management. For this end, a literature review was carried out in 120 Brazilian academic journals in which 124 papers were identified, from 2008 until 2013. When considering the Triple Bottom Line approach, the results show that sustainability research in Brazil is focusing on the environmental dimension and SCM research is focusing on the economic dimension. Additional inputs are provided by integrating the governance dimension in the analysis to underline which actions and policies are discussed in Brazil at a corporate level. To support the results a consultation of experts in the field of sustainability in Brazil was fulfilled, and three case examples are presented to explain some of the research results. The findings on publications in Brazil contrast with international studies, particularly on the topic of social performance and management in supply chains. One of the main conclusions is that there are large opportunities to increase publications about sustainability and SCM in the country and that Brazil presents some specificities in the field that researchers and managers shall consider.

  11. Charcot and Brazil Charcot e o Brasil

    Directory of Open Access Journals (Sweden)

    Hélio A. Ghizoni Teive


    Full Text Available OBJECTIVE: To describe the relationship between Professor Charcot and Brazil. BACKGROUND: During the XIX century, French Neurology and its most prominent figure, Professor Charcot, dominated the area of nervous system diseases in the world. METHOD: We have reviewed some of the main publications about Charcot's life, the biography of Dom Pedro II, Emperor of Brazil and the development of Neurology in Brazil. RESULTS: Among the most important patients in Charcot's practice was the Emperor of Brazil. Dom Pedro II became a close friend of Charcot and he was a distinguished guest at Charcot's house, particularly at Tuesday soirées on boulevard St. Germain. In 1887, during the visit of Dom Pedro II to France, Charcot evaluated him and made the diagnosis of surmenage. In 1889, Dom Pedro II was deposed and went to Paris, where he lived until his death in 1891. Charcot signed the death certificate and gave the diagnosis of pneumonitis. Charcot had a passionate affection for animals, a feeling shared by Dom Pedro II. Dom Pedro II was affiliated to the French Society for the Protection of Animals. It is conceivable that Charcot's little monkey, from South America, was given to him by Dom Pedro II. The Brazilian Neurological School was founded by Professor A . Austregésilo in 1911, in Rio de Janeiro. At the time, of Charcot's death in 1893, his influence was still very important in the whole world. He and his pupils played a major role in the development of Brazilian Neurology. CONCLUSION: Professor Charcot had a close relationship with the Emperor of Brazil, Dom Pedro II. He was his private physician and they were close friends. The neurological school, created by professor Charcot, contributed significantly, albeit in an indirect way, to the development of Brazilian Neurology, starting in 1911, in Rio de Janeiro, by Professor A . Austregésilo.OBJETIVO: Descrever a relação entre o Professor Charcot e o Brasil. FUNDAMENTO: Durante o século XIX, a

    Plastic films used to make market bags are based on polymers such as polyethylene, polystyrene and polypropylene, these materials require a long time to degrade in the environment. The alternative technologies of polymers have been developed to reduce the degradation time and the impact on the environment caused by the conventional materials, using pro-degrading additives or by the development biodegradable polymers. In Brazil, the laws of some municipalities require the use of biodegradable material in the production of market bags but the absence of specific surveillance policies makes its chemical composition unknown. In this paper, we analyzed 7 samples that was obtained from a a trading company and commercial market of Belo Horizonte . The samples were characterized by TGA / DTA , XRF , FTIR and MEV which allowed the identification and evaluation of the thermal behavior of the material in inert and oxidizing atmosphere. (author)

    The sugar industry goes through an important moment: invest and develop to supply future demand, mainly by fuel alcohol (around 70% of new vehicles sales are from flex fuel models - and the majority of these vehicles are supplied by alcohol). Due to this foreseeable increase of alcohol demand, sugar industry has already announced 41 new projects, which will contribute with the milling of 70 million tons of sugar cane by the conclusion of these plants. In this phase of expansion, the alcohol market must be pressured for the demand, managing the supplying of the domestic and external markets. With this scenario and the possibility of sector growth which has an important role in Brazil development, this work evaluates the economic impacts of the new plants implementation investments.

    Currently, Brazil is experiencing an expansion of sugarcane plantations, which makes the country the world's largest producer of sugarcane. With the bagasse generated during the process, is generated the bagasse ash cane sugar (CBC) which consists mainly of silicon dioxide (SiO{sub 2}) and presents as potential alternative raw material for the production of cement composites. In this context, the objective of this study is to evaluate the reactivity of the CBC through physical and chemical analysis, for the production of mortars. The study of the CBC was performed by means of XRF testing, XRD, SEM and ADL. Mortar specimens with different percentages of CBC in partial replacement of Portland cement, for analysis of compressive strength were also produced. Despite the mixtures with additions have lower resistance to conventional mortars, the results showed the potential of the CBC as reactive mineral addition. (author)

  16. Prevalence of syphilis in pregnancy and prenatal syphilis testing in Brazil: Birth in Brazil study (United States)

    Domingues, Rosa Maria Soares Madeira; Szwarcwald, Celia Landmann; Souza, Paulo Roberto Borges; Leal, Maria do Carmo


    OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test) and 41.2% (two tests), and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25). A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with social inequalities in access to health care units, coupled with other gaps in health assistance, have led to the persistence of congenital syphilis as a major public health problem in Brazil.

  18. A new Magnetic Observatory in Pantanal - Brazil (United States)

    Siqueira, F.; Pinheiro, K.; Linthe, H.


    The aim of a Magnetic Observatory is to register the variations of the Earth's magnetic field in a long temporal scale. Using this data it is possible to study field variations of both external and internal origins. The external variations concern interactions between the magnetosphere and the solar wind, in general are measured in a short time scale. The internal field generated by convection of a high electrical conductivity fluid in the external core by a mechanism known as the geodynamo. Usually the internal field time variations are longer than in the external field and are called secular variations. Measurements carried out over the last century suggest that field intensity is decreasing rapidly. The decreasing of the field's intensity is not the same around the globe, especially at the SAMA (South Atlantic Magnetic Anomaly) regions, where this reduction is occurring faster. The global distribution of magnetic observatories is uneven, with few observatories in South America. In Brazil, there are three magnetic observatories, but only Vassouras Observatory (VSS- RJ) is part of the INTERMAGNET network. The National Observatory has plans to install seven new observatories in Brazil. Pantanal was the chosen location for installing the first observatory because of its privileged location, close to the SAMA region, and its data can contribute to more information about its origin. We followed the procedures suggested by the IAGA to build this observatory. The first step is to perform a magnetic survey in order to avoid strong magnetic gradients in the location where the absolute and variometers houses will be installed. The next step, the construction of the observatory, includes the selection of special non-magnetic material for the variometer and absolute houses. All materials used were previously tested using a proton magnetometer GSM-19. After construction of the whole infrastructure, the equipment was installed. This Project is a cooperation between Brazilian

    Horta, Rogério Lessa; Andersen, Cristine Scattolin; Pinto, Raquel Oliveira; Horta, Bernardo Lessa; Oliveira-Campos, Maryane; Andreazzi, Marco Antonio Ratzsch de; Malta, Deborah Carvalho


    Evaluate the school environments to which ninth-year students are exposed in Brazil and in the five regions of the country according to health promotion guidelines. Cross-sectional study from 2012, with a representative sample of Brazil and its macroregions. We interviewed ninth-year schoolchildren and managers of public and private schools. We proposed a score of health promotion in the school environment (EPSAE) and estimated the distribution of school members according to this score. Crude and adjusted odds ratios (OR) were used, by ordinal regression, to determine the schoolchildren and schools with higher scores, according to the independent variables. A student is more likely to attend a school with a higher EPSAE in the South (OR = 2.80; 95%CI 2.67-2.93) if the school is private (OR = 4.52; 95%CI 4.25-4.81) and located in a state capital, as well as if the student is 15 years of age or older, has a paid job, or has parents with higher education. The inequalities among the country's regions and schools are significant, demonstrating the need for resources and actions that promote greater equity. Avaliar os ambientes escolares aos quais estão expostos estudantes do nono ano no Brasil e nas cinco regiões do país segundo diretrizes de promoção da saúde. Estudo transversal, de 2012, com amostra representativa do Brasil e suas macrorregiões. Escolares do nono ano e gestores de escolas públicas e privadas foram entrevistados. Foi proposto o Escore de Promoção de Saúde no Ambiente Escolar (EPSAE) e foi estimada a distribuição dos escolares segundo esse escore e segundo odds ratio (OR) brutas e ajustadas, por regressão ordinal, para exposição dos escolares a escolas com escores mais elevados, segundo as variáveis independentes. Um escolar tem mais probabilidade de frequentar escola com EPSAE elevado na região Sul (OR = 2,80; IC95% 2,67-2,93) se a escola for privada privada (OR = 4,52; IC95% 4,25-4,81) e estiver localizada em capital de estado e se o

  20. The privatization of medical education in Brazil: trends and challenges. (United States)

    Scheffer, Mário C; Dal Poz, Mario R


    Like other countries, Brazil is struggling with issues related to public policies designed to influence the distribution, establishment, supply and education of doctors. While the number of undergraduate medical schools and places available on medical schools has risen, the increase in the number of doctors in Brazil in recent decades has not benefitted the population homogeneously. The government has expanded the medical schools at the country's federal universities, while providing incentives for the creation of new undergraduate courses at private establishments. This article examines the trends and challenges of the privatization of medical education in Brazil. This is a descriptive, cross-sectional study based on secondary data from official government databases on medical schools and courses and institutions offering such courses in Brazil. It takes into account the year when the medical schools received authorization to initiatte the activities, where they are situated, whether they are run by a public or private entity, how many places they offer, how many students they have enrolled, and their performance according to Ministry of Education evaluations. Brazil had 241 medical schools in 2014, offering a total of 20,340 places. The private higher education institutions are responsible for most of the enrolment of medical students nationally (54 %), especially in the southeast. However, enrolment in public institutions predominate more in the capitals than in other cities. Overal, the public medical schools performed better than the private schools in the last two National Exam of Students' (ENADE). The privatization of the teaching of medicine at undergraduate level in Brazil represents a great challenge: how to expand the number of places while assuring quality and democratic access to this form of education. Upon seeking to understand the configuration and trends in medical education in Brazil, it is hoped that this analysis may contribute to a broader

    In December 2013, an outbreak of Chikungunya virus (CHIKV) caused by the Asian genotype was notified in the Caribbean. The outbreak has since spread to 38 regions in the Americas. By September 2014, the first autochthonous CHIKV infections were confirmed in Oiapoque, North Brazil, and in Feira de Santana, Northeast Brazil. We compiled epidemiological and clinical data on suspected CHIKV cases in Brazil and polymerase-chain-reaction-based diagnostic was conducted on 68 serum samples from patients with symptom onset between April and September 2014. Two imported and four autochthonous cases were selected for virus propagation, RNA isolation, full-length genome sequencing, and phylogenetic analysis. We then followed CDC/PAHO guidelines to estimate the risk of establishment of CHIKV in Brazilian municipalities. We detected 41 CHIKV importations and 27 autochthonous cases in Brazil. Epidemiological and phylogenetic analyses indicated local transmission of the Asian CHIKV genotype in Oiapoque. Unexpectedly, we also discovered that the ECSA genotype is circulating in Feira de Santana. The presumed index case of the ECSA genotype was an individual who had recently returned from Angola and developed symptoms in Feira de Santana. We estimate that, if CHIKV becomes established in Brazil, transmission could occur in 94% of municipalities in the country and provide maps of the risk of importation of each strain of CHIKV in Brazil. The etiological strains associated with the early-phase CHIKV outbreaks in Brazil belong to the Asian and ECSA genotypes. Continued surveillance and vector mitigation strategies are needed to reduce the future public health impact of CHIKV in the Americas.

  2. Using the Portuguese version of the Bicultural Scale in Brazil. (United States)

    Zubaran, Carlos; Foresti, Katia; Persch, Karina Nunes


    Brazil has received influxes of people, mainly from Africa, Europe and Japan, forming one of the most heterogeneous populations in the world. Some groups, particularly in Southern Brazil, have retained their original cultural traditions, whilst acquiring elements of the typical local Brazilian cultural identity. This is the first study designed to formally evaluate biculturality in Brazil. To psychometrically assess and validate the Portuguese version of the Bicultural Scale (BS) in Brazil. The BS was adapted and translated to Portuguese and tested for the first time in Brazil in a sample of descendants (n = 160) from four immigrant groups and respective locations in Southern Brazil. A series of psychometric tests were conducted in order to examine the validity of the Portuguese version of the BS. Analyses of variance across scores for all subgroups were also conducted. Factor analysis revealed two main factors contributing to most of the variance in scores. The 10 items measuring affiliation with minority cultural characteristics and the typical Brazilian culture yielded Cronbach's alpha coefficients of 0.69 and 0.78 respectively, whereas the overall Cronbach's alpha for all 20 items of the BS was 0.67. There was a significant correlation between items related to the typical Brazilian culture and the generation since immigration of research participants (r = 0.23, p = 0.004). The mean time taken to complete the questionnaire was 7.4 minutes. The results indicate that the Portuguese version of the BS is a valid, reliable and easy-to-use instrument to assess biculturality experienced by descendants of immigrants in southern Brazil.

  4. Brazil's urban laboratory takes the strain. (United States)

    Cavalcanti, C


    The city of Curitiba, in southern Brazil, has been known for its environmental-friendly urban planning. Its quality of life has encouraged the natural growth of the city, which has doubled its population to over 1.3 million in the last 20 years while retaining 52 m of green area per inhabitant. In this article, the city's efforts to retain its success in the face of a growing population are documented. An integrated transport system has been created, a main commercial street was turned into a pedestrian street, the building of the Wire Opera and the Free Environment University was created, and the decentralization of the country's health system, and the launching of a program of waste sorting. All these accomplishments subsequently generated tourism, bringing in an income of about 4% of the city's net income. In addition, they have helped the 300,000 inhabitants of the city's slums with their rubbish by selling them carts on a low installment price. Migratory flow has been curbed since the creation of the Return House, wherein social workers offer free tickets to potential migrants; and the Vila Rural (Rural Town), consisting of small rural properties where peasant farmers will be able to farm in between industrial jobs. In conclusion, if Curitiba's Institute of Urban Research and Planning team is successful in transposing to the State its achievements in the municipal administration, by the year 2000 Curitiba will have proved to be the seed of a revolution that will improve the development of the whole region.

  5. Heavy rainfall equations for Santa Catarina, Brazil

    Directory of Open Access Journals (Sweden)

    Álvaro José Back


    Full Text Available Knowledge of intensity-duration-frequency (IDF relationships of rainfall events is extremely important to determine the dimensions of surface drainage structures and soil erosion control. The purpose of this study was to obtain IDF equations of 13 rain gauge stations in the state of Santa Catarina in Brazil: Chapecó, Urussanga, Campos Novos, Florianópolis, Lages, Caçador, Itajaí, Itá, Ponte Serrada, Porto União, Videira, Laguna and São Joaquim. The daily rainfall data charts of each station were digitized and then the annual maximum rainfall series were determined for durations ranging from 5 to 1440 min. Based on these, with the Gumbel-Chow distribution, the maximum rainfall was estimated for durations ranging from 5 min to 24 h, considering return periods of 2, 5, 10, 20, 25, 50, and 100 years,. Data agreement with the Gumbel-Chow model was verified by the Kolmogorov-Smirnov test, at 5 % significance level. For each rain gauge station, two IDF equations of rainfall events were adjusted, one for durations from 5 to 120 min and the other from 120 to 1440 min. The results show a high variability in maximum intensity of rainfall events among the studied stations. Highest values of coefficients of variation in the annual maximum series of rainfall were observed for durations of over 600 min at the stations of the coastal region of Santa Catarina.

  6. Application of Multiple Evaluation Models in Brazil

    Rafael Victal Saliba


    Full Text Available Based on two different samples, this article tests the performance of a number of Value Drivers commonly used for evaluating companies by finance practitioners, through simple regression models of cross-section type which estimate the parameters associated to each Value Driver, denominated Market Multiples. We are able to diagnose the behavior of several multiples in the period 1994-2004, with an outlook also on the particularities of the economic activities performed by the sample companies (and their impacts on the performance through a subsequent analysis with segregation of companies in the sample by sectors. Extrapolating simple multiples evaluation standards from analysts of the main financial institutions in Brazil, we find that adjusting the ratio formulation to allow for an intercept does not provide satisfactory results in terms of pricing errors reduction. Results found, in spite of evidencing certain relative and absolute superiority among the multiples, may not be generically representative, given samples limitation.

    Several farms in the Northeast of Brazil were investigated for Mycobacterium avium subsp. paratuberculosis infection in order to identify the occurrence of paratuberculosis in buffaloes. Samples were obtained from 17 farms, two slaughter houses, and a quarantine area in the Northeast. About 15,000 buffaloes of the Murrah, Mediterranean, and Jafarabadi breed as well as their crossbreeds were evaluated for meat, dairy, and mixed farms with semi-intensive or extensive breeding practices. For diagnostic purposes, postmortem and histopathological examination, including Ziehl-Neelsen test of fecal smears and scraped intestinal mucosa were performed. PCR was applied for fecal samples, mesenteric lymph nodes, and intestines. Six Johne's disease-positive farms, which together with those previously identified, indicate that the disease is spread through the Brazilian Northeast, similar to what occurs in cattle herds in other regions of the country. The increase in prevalence of paratuberculosis is a consequence of introduction of animals from other regions without adequate veterinary assistance and due to the little official attention paid to this initially silent and chronic disease.

  8. "Nerves" and tranquilizer use in rural Brazil. (United States)

    Rozemberg, B; Manderson, L


    Drawing on data from a morbidity survey of sampled households in 25 small villages in Espirito Santo, Brazil, this article is concerned with reports of "nerves" (nervos) or nerve problems (problema de nervos). Reported cases of nervos (30 percent of all reports of illness) included a variety of symptoms: insomnia, body pains, dizziness, trembling, weakness, and emotional states ranging from feelings of sadness to anger. In one-third of the accounts, "overwork" was mentioned as the main cause, due both to its direct physical effect and to stress related to economic hardship and responsibility. In 88 percent of the cases, the afflicted person regularly used at least one psychotropic drug to relieve symptoms. Daily use of drugs occurred in 68 percent of the cases, and in 47 percent of cases people were reported as "dependent" on the drugs. The extensive use of psychotropic drugs suggests medicalization of nervos, creating a sick role for patients and keeping at an individual level the problems resulting in nervos.

  9. Brachiaria spp. poisoning of ruminants in Brazil

    Directory of Open Access Journals (Sweden)

    B. Riet-Correa


    Full Text Available Brachiaria species are the most important grasses for cattle production in Brazil. However, a limiting factor for the use of Brachiaria spp. is their toxicity. Most outbreaks of hepatogenous photosensitization are caused by B. decumbens; however B. brizantha, B. humidicola and B. ruziziensis can also cause poisoning. The poisoning affects cattle, sheep, goats and buffalo. Sheep are more susceptible than other animal species and the young are more susceptible than adults. There are differences in susceptibility among animals of the same species and it has been suggested that this resistance is genetic. Also has been suggested that buffalo and probably some sheep are resilient, i.e. when poisoned these animals have histologic lesions and high GGT serum concentrations, but do not show clinical signs. In general, saponin concentrations are higher in growing plants, but outbreaks occur all over the year, probably due to unexplained rise in saponin concentration in the plant. A clinical syndrome of progressive weight loss and death, without photosensitization, has been reported in cattle poisoned by B. decumbens. Main preventive measures are based on the selection of resistant or resilient animals and on the development of Brachiaria species or varieties with low saponin concentration.

    Mariza Zanchi

    Full Text Available Summary Objective: To determine the pregnancy recurrence among adolescents and young people in a city located in the extreme south of Brazil and to identify associated factors. Method: One hundred and twelve (112 women participated, having delivered their children in 2010, while adolescents. The sample was stratified in two stages, being the first a census of the whole population of the city and the second a convenience sample. For statistical analysis, Pearson Chi-square test was used, with a significance level of 5%. Results: The recurrence rate was 53.6%, with an average of 28.6 months. At the time of delivery, in 2010, recurrence was significantly associated with level of education (p=0.044 as well as not being in school (p=0.036. In 2014, the factors associated were level of education (p<0.001, transcript of grades (p=0.030 and income (p=0.030. Conclusion: Recurrence of teenage pregnancy represents a lack of importance given to formal education, a fact that mitigates the opportunities and hinders insertion in the labor market, creating a cycle of social inequality. Multidisciplinary efforts involving schools, health services and the youth in educational activities are thus vital, aiming at critical thinking to transform reality.

  11. Brazil's national programs targeting childhood obesity prevention. (United States)

    Silva, A C F; Bortolini, G A; Jaime, P C


    In Brazil, overweight and obesity are increasing in all age and income groups. Currently, 7.3% of children under 5 years of age, 30% of children aged 5-9 and 20% of preadolescents aged 10-19 are overweight. In the primary health-care (PHC) environment, activities are carried out to monitor eating habits and nutrition, as well as to prevent unhealthy habits and promote healthy eating behaviors consistent with the dietary guidelines for Brazilian children. Comprehensive care is being provided to overweight individuals. The Brazilian Breastfeeding and Complementary Feeding Strategy was launched in 2009 to support health teams to counsel families about healthy feeding, focused on child health and obesity prevention. Within the school environment, the School Health Program offers activities that are developed by PHC teams together with education professionals to focus on assessing health conditions, prevention and health promotion. To improve the nutritional profile of processed foods, terms of cooperation have been signed with the food industry to reduce fat and sodium content. Food industry advertising and marketing to infants and young children are now regulated by the Brazilian Regulation for the Marketing of Foods to Infants and Young Children.

  12. Incidence of anabolic steroid counterfeiting in Brazil. (United States)

    da Justa Neves, Diana Brito; Marcheti, Ravane Gracy Ament; Caldas, Eloisa Dutra


    This retrospective study reports data obtained from the National Institute of Criminalistics of the Brazilian Federal Police Department (DPF) on 3676 anabolic products seized between 2006 and 2011. Anabolic androgenic steroids (AAS) were declared on the labels of 96.2% of the products. About one third of the products declared to be from Paraguay, and 14.3% from Brazil. Stanozolol, testosterone and nandrolone were the substances most declared on the labels. Package and qualitative chemical analyses (performed on 2818 products) found that 31.7% of the seized products were counterfeit, with an increase in the counterfeit detection rate during the period. Almost half of the fake products did not contain the declared substances, and 28.3% had only non-declared substances. Testosterone and its esters were responsible for 45% of the 582 cases of non-declared drug detection. Package analysis alone was responsible for the identification of 4.6% of all counterfeit products. These results indicate the need for a continuous effort by the government aimed at decreasing the availability of these products in the country. Copyright © 2013 Elsevier Ireland Ltd.

    Full Text Available The proposal and implementation of parceling real estate into smaller lots in Brazil is done according to legal and technical formalities. However, these instruments have proved inefficient in reducing the resulting environmental impacts. The ambiguities of the federal, state and municipal laws and regulations have limited the effectiveness of the actions of urban administrators. Law 10257/2001 emerged as an alternative to overcome these difficulties, proposing the adoption of neighborhood impact studies as an instrument to evaluate new proposals of urban occupation for purposes of environmental licensing. Thus, the purpose of this law is to provide the foundations for municipal public authorities to establish criteria for the assessment, mitigation and compensation of impacts resulting from new occupations. However, the very vagueness of the generic nature of this federal law and its incorrect application in the municipal sphere has posed the greatest obstacles to the good use of this instrument of urban environmental management. These deficiencies are classified herein in the categories of philosophical, technical and operational problems. The problems of a philosophical nature lead to technical difficulties, which in turn trigger operational deficiencies. This article discusses these deficiencies and points out ways to reduce them.

    Mario Lucio de Oliveira Novaes


    Full Text Available ABSTRACT: Objectives: Vaccines represent an important advancement for improving the general health of a population. The effective recording of vaccine data is a factor for the definition of its supply chain. This study investigated vaccine data recording relatively to data collected from vaccination rooms and data obtained from a government-developed Internet platform. Methods: The monthly recorded total number of diphtheria and tetanus toxoids and pertussis vaccine (alone or in combination with the Haemophilus influenzae type b conjugate vaccine doses administered in a medium-sized city of the Southeast region of Brazil was collected for the period January/2006 through December/2010 from two sources: City level (directly from vaccination rooms, the study "gold standard", and Federal level (from an Internet platform developed by the country government. Data from these sources were compared using descriptive statistics and the Percentage error. Results: The data values made available by the Internet platform differed from those obtained from the vaccination rooms, with a Percentage error relatively to the actual values in the range [-0.48; 0.39]. Concordant values were observed only in one among the sixty analyzed months (1.66%. Conclusions: A frequent and large difference between the number of diphtheria and tetanus toxoids and pertussis vaccine doses administered in the two levels was detected.

    Radioactive liquid waste needs special attention and requires suitable treatment before deposition. Among the potential technologies under development for the treatment of liquid radioactive wastes the biosorption has been highlighted by being an efficient and low cost technique. Biosorption process involves the exchange of ions contained in the biomass matrix by others present in solution. There are many biomasses that could be applied in treatment of radioactive wastes, for example, agricultural residues and macrophyte. The aim of this study is evaluate the ability of the Azolla sp., a floating aquatic plant, to absorb uranium in solution. Azolla sp. is a macrophyte that has been used to treat effluents containing heavy metals. The biosorption capacity of uranium by Azolla sp. was experimentally determined and modeled by isotherms. Experiments were performed to determine metal uptake, and then the solutions were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES). The isotherms applied to model the data was Langmuir, Freundlich, Sips Toth, Redlich Peternson, Two-Site-Langmuir, Radke Prausnitz to develop a technique for the treatment of radioactive liquid waste generated at the Nuclear and Energy Research Institute (IPEN-CNEN/SP), Brazil.

  16. Outraged governance. Brazil : a route of Danger

    Directory of Open Access Journals (Sweden)

    Matusalém Gonçalves Pimenta


    Full Text Available This article aims to determine the risks taken by Brazil for not fulfilling an Inter- national Resolution. The research method chosen was the systemic / comparative. In regard to Pilotage, the International Maritime Organization (IMO adopted the A-960 (23 Resolution, and has upheld it ever since towards a global governance, approach and positioning. The authors of this article have chosen to focus in five fundamental princi- ples, extracted from the Resolution. It has been established that these principles remain paramount to almost all member countries, and, whenever they choose to uphold them, all undertake a standpoint of good governance. This work initially analyses and compa- res the sub studio Resolution standards towards the present brazilian pilotage model. Moreover, it identifies some discrepancies that lead to non-compliances. Furthermore, it correlates the violation of fundamental principles to three massive maritime accidents that mankind shall not be proud of, i.e. Exxon Valdez, Sea Empress and Costa Concordia. Lastly, final conclusion is that, whenever the international IMO standards are disregarded by Brazilian Authorities, they endanger - most unacceptably - the maritime environment, the safety of navigation, and of human life at sea.

  17. Perspectives for Sustainable Aviation Biofuels in Brazil

    Directory of Open Access Journals (Sweden)

    Luís A. B. Cortez


    Full Text Available The aviation industry has set ambitious goals to reduce carbon emissions in coming decades. The strategy involves the use of sustainable biofuels, aiming to achieve benefits from environmental, social, and economic perspectives. In this context, Brazilian conditions are favorable, with a mature agroindustry that regularly produces automotive biofuel largely adopted by Brazilian road vehicles, while air transportation has been growing at an accelerating pace and a modern aircraft industry is in place. This paper presents the main conclusions and recommendations from a broad assessment of the technological, economic, and sustainability challenges and opportunities associated with the development of drop-in aviation biofuels in Brazil. It was written by a research team that prepared the initial reports and conducted eight workshops with the active participation of more than 30 stakeholders encompassing the private sector, government institutions, NGOs, and academia. The main outcome was a set of guidelines for establishing a new biofuels industry, including recommendations for (a filling the identified research and development knowledge gaps in the production of sustainable feedstock; (b overcoming the barriers in conversion technology, including scaling-up issues; (c promoting greater involvement and interaction between private and government stakeholders; and (d creating a national strategy to promote the development of aviation biofuels.

  18. Palliative care and elderly health in Brazil

    Directory of Open Access Journals (Sweden)

    Angela Maria Amaral Soares Abou Ali


    Full Text Available In recent years elderly population is increasing substantially, about 650,000 per year, as well as the concept of unifamílies, ie, families consisting of a single person. In this paper, is proposed a reflection about health of elderly in Brazil, and the conditions of a chronic disease and its acute state - terminal. In the actual society, capitalist and capitalized, the individual is valued by his production, losing his value when acquires a disabling illnesses. There is a growing need for work, and each time there is less time and resources to manage the permanence of an elderly patient at home, or pay for a caregiver. This situation leads families to resort to hospitalization, which in turn makes the hospitals overcrowded with patients in this state, affecting both emergency care as the treatment of chronic patients. This fact occurs due to lack of hospital infrastructure, as well by the lack of units of the healthy system capable of providing palliative care. The questioning about the elderly who need palliative care, and reflection about the type of care dispended for this kind of patient, should be the focal point of professional's reflections, capable to lead him to a new way of thinking and, consequently, to inspire him to act in a new way.

    de Azevedo, Ana Beatriz Cordeiro; Ferraz, Marcos Bosi; Ciconelli, Rozana Mesquita


    The present study aimed to determine indirect costs of rheumatoid arthritis (RA) in a sample of patients followed at a public health-care facility in Brazil. Factors potentially associated with higher indirect costs in these patients were also investigated. This cross-sectional study included patients between 18 and 65 years old with RA according to the American College of Rheumatology criteria. Patients who were working, on sick leave or retired early due to RA were invited to participate in the survey. A systematic structured interview was conducted in all patients including demographic, socioeconomic, and clinical variables and an experienced rheumatologist examined all patients. Estimates of the indirect costs in the preceding 12 months were performed using the human-capital approach based on the society perspective. Multiple linear regression models were used to determine the variables associated with higher indirect costs. A total of 192 patients were included in the study. Forty-seven of them (24.5%) had retired early due to RA, 62 others (32.3%) were on sick leave due to RA while 83 patients (43.2%) were working at the time of the interview. Estimated indirect cost for this population was US$ 466,107.81 or US$ 2,423.51 per patient per year. Factors associated with higher costs were RA poor functional class, high socioeconomic status and male patients (p Indirect costs were higher in patients with poor functional classes, high socioeconomic status, and men.

    Bioethanol (fuel alcohol) has been produced by industrial alcoholic fermentation processes in Brazil since the beginning of the twentieth century. Currently, 432 mills and distilleries crush about 625 million tons of sugarcane per crop, producing about 27 billion liters of ethanol and 38.7 million tons of sugar. The production of bioethanol from sugarcane represents a major large-scale technology capable of producing biofuel efficiently and economically, providing viable substitutes to gasoline. The combination of immobilization of CO{sub 2} by sugarcane crops by photosynthesis into biomass together with alcoholic fermentation of this biomass has allowed production of a clean and high-quality liquid fuel that contains 93% of the original energy found in sugar. Over the last 30 years, several innovations have been introduced to Brazilian alcohol distilleries resulting in the improvement of plant efficiency and economic competitiveness. Currently, the main scientific challenges are to develop new technologies for bioethanol production from first and second generation feedstocks that exhibit positive energy balances and appropriately meet environmental sustainability criteria. This review focuses on these aspects and provides special emphasis on the selection of new yeast strains, genetic breeding, and recombinant DNA technology, as applied to bioethanol production processes.

  1. Fossilized excreta associated to dinosaurs in Brazil (United States)

    Souto, P. R. F.; Fernandes, M. A.


    This work provides an updated register of the main occurrences of fossilized excreta (coprolites and urolites) associated with dinosaurs found in the Brazil. The goal is to provide a relevant guide to the interpretation of the environment in the context of Gondwana. In four geographic areas, the excreta are recovered from Cretaceous sedimentary deposits in outcrops of the Bauru and São Luis basins and the Upper Jurassic aeolian deposits of the Parana Basin in the state of São Paulo. The coprolites were analyzed by X-ray diffraction and X-ray fluorescence methods. The results of these analyses reveal compositions that differ from the surrounding matrix, indicating a partial substitution of the organic material due to the feeding habits of the producers. Additionally, we describe the urolite excavations in epirelief and hyporelief, the result of gravitational flow the impact from urine jets on sand. These are associated with ornithopod and theropod dinosaur footprints preserved in the aeolian flagstones of the Botucatu Formation, Parana Basin.

  4. Miracle drug: Brazil approves never-tested cancer medicine. (United States)

    Kuchenbecker, Ricardo S; Mota, Daniel M


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

    Thiago Hérick de Sá


    Full Text Available ABSTRACT OBJECTIVE To present national estimates regarding walking or cycling for commuting in Brazil and in 10 metropolitan regions. METHODS By using data from the Health section of 2008’s Pesquisa Nacional por Amostra de Domicílio (Brazil’s National Household Sample Survey, we estimated how often employed people walk or cycle to work, disaggregating our results by sex, age range, education level, household monthly income per capita, urban or rural address, metropolitan regions, and macro-regions in Brazil. Furthermore, we estimated the distribution of this same frequency according to quintiles of household monthly income per capita in each metropolitan region of the country. RESULTS A third of the employed men and women walk or cycle from home to work in Brazil. For both sexes, this share decreases as income and education levels rise, and it is higher among younger individuals, especially among those living in rural areas and in the Northeast region of the country. Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. CONCLUSIONS Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making

  6. Angiostrongylus cantonensis and rat lungworm disease in Brazil. (United States)

    Thiengo, Silvana Carvalho; Simões, Raquel de Oliveira; Fernandez, Monica Ammon; Maldonado, Arnaldo


    The metastrongyloid nematode genus Angiostrongylus includes 18 species, two of which are relevant from a medical standpoint, Angiostrongylus costaricensis and Angiostrongylus cantonensis. The first was described from Costa Rica in 1971 and causes abdominal angiostrongyliasis in the Americas, including in Brazil. Angiostrongylus cantonensis, first described in 1935 from Canton, China, is the causative agent of eosinophilic meningitis. The natural definitive hosts are rodents, and molluscs are the intermediate hosts. Paratenic or carrier hosts include crabs, freshwater shrimp, amphibians, flatworms, and fish. Humans become infected accidentally by ingestion of intermediate or paratenic hosts and the parasite does not complete the life cycle as it does in rats. Worms in the brain cause eosinophilic meningitis. This zoonosis, widespread in Southeast Asia and the Pacific islands, has now been reported from other regions. In the Americas there are records from the United States, Cuba, Jamaica, Brazil, Ecuador, and Haiti. In Brazil seven human cases have been reported since 2007 from the southeastern and northeastern regions. Epidemiological studies found infected specimens of Rattus norvegicus and Rattus rattus as well as many species of molluscs, including the giant African land snail, Achatina fulica, from various regions of Brazil. The spread of angiostrongyliasis is currently a matter of concern in Brazil.

  7. Where are the trees outside forest in Brazil?

    Directory of Open Access Journals (Sweden)

    Hubert de Foresta


    Full Text Available Trees outside forests (ToF is often a misunderstood category. This is the case in Brazil as shown by the lack of data on ToF reported until now by the country. In this article, ToF are understood in relation to the FAO definition of forest because it is the definition used in Brazil for the National Forest Inventory. I provide a definition of ToF, detail the main sets as inferred from this definition, propose to focus on a category of ToF as an efficient and realistic first step towards the assessment of ToF countrywide, and I illustrate the diversity of ToF-based systems in Brazil, from relatively isolated trees in agroforestry fields to dense mixed tree formations that cannot be distinguished from forests on satellite images. A recent publication has placed Brazil as the world leader in terms of the total biomass carbon stored by one ToF set, trees on agricultural land. This result could stimulate the desire for Brazil to better assess not only trees on agricultural land but also trees on urban land, the two major sets of trees outside forests. The present paper can help those who will undertake this challenging and exciting task.

  8. Humane Education in Brazil: Organisation, Challenges and Opportunities. (United States)

    Humane education and the debate on alternatives to harmful animal use for training is a relatively recent issue in Brazil. While animal use in secondary education has been illegal since the late 1970s, animal use in higher science education is widespread. However, alternatives to animal experiments in research and testing have recently received attention from the Government, especially after the first legislation on animal experiments was passed, in 2008. This article proposes that higher science education should be based on a critical and humane approach. It outlines the recent establishment of the Brazilian Network for Humane Education (RedEH), as a result of the project, Mapping Animal Use for Undergraduate Education in Brazil, which was recognised by the 2014 Lush Prize. The network aims to create a platform to promote change in science education in Brazil, starting by quantitatively and qualitatively understanding animal use, developing new approaches adapted to the current needs in Brazil and Latin America, and communicating these initiatives nationally. This paper explores the trajectory of alternatives and replacement methods to harmful animal use in training and education, as well as the status of humane education in Brazil, from the point of view of educators and researchers engaged with the network.

  9. Scorpionism in Brazil in the years 2000 to 2012. (United States)

    Reckziegel, Guilherme Carneiro; Pinto, Vitor Laerte


    Scorpionism is a serious public health problem in Brazil. Nationwide epidemiological analyses of scorpion stings are scarce. In this context, the present study aims to provide an epidemiological analysis of accidents involving scorpions in Brazil. An analytical epidemiological study of the scorpion accidents reported in the Information System for Notifiable Diseases (SINAN) was conducted from 2000 to 2012 in Brazil. During this period, 482,616 accidents and 728 deaths were reported. The annual average incidence and mortality rates per 100,000 inhabitants were 19.6 and 0.030, respectively, with annual average lethality rate of 0.16%. The highest accident frequency was recorded in male subjects, aged 20-49 years, from September to December and in urban areas, except in the northern region of the country, where accidents were most frequent in June and July, and in rural areas. Males up to age 9 and rural areas were defined as an age group and area for greatest death risk, respectively. Scorpionism in Brazil is a predominantly urban health problem that mostly affects people at an economically active age. The Northeast and Southeast hold the majority of cases and deaths, as well as the highest annual incidence and mortality averages, but the Central West and North presented the highest average annual lethality rates. The epidemiological changes described in this study highlight the need for intensifying health surveillance actions to prevent scorpion accidents in Brazil.

  10. Potential geographic distribution of hantavirus reservoirs in Brazil.

    Directory of Open Access Journals (Sweden)

    Stefan Vilges de Oliveira

    Full Text Available Hantavirus cardiopulmonary syndrome is an emerging zoonosis in Brazil. Human infections occur via inhalation of aerosolized viral particles from excreta of infected wild rodents. Necromys lasiurus and Oligoryzomys nigripes appear to be the main reservoirs of hantavirus in the Atlantic Forest and Cerrado biomes. We estimated and compared ecological niches of the two rodent species, and analyzed environmental factors influencing their occurrence, to understand the geography of hantavirus transmission. N. lasiurus showed a wide potential distribution in Brazil, in the Cerrado, Caatinga, and Atlantic Forest biomes. Highest climate suitability for O. nigripes was observed along the Brazilian Atlantic coast. Maximum temperature in the warmest months and annual precipitation were the variables that most influence the distributions of N. lasiurus and O. nigripes, respectively. Models based on occurrences of infected rodents estimated a broader area of risk for hantavirus transmission in southeastern and southern Brazil, coinciding with the distribution of human cases of hantavirus cardiopulmonary syndrome. We found no demonstrable environmental differences among occurrence sites for the rodents and for human cases of hantavirus. However, areas of northern and northeastern Brazil are also apparently suitable for the two species, without broad coincidence with human cases. Modeling of niches and distributions of rodent reservoirs indicates potential for transmission of hantavirus across virtually all of Brazil outside the Amazon Basin.

  11. [Public policies for the elderly in Brazil: an integrative review]. (United States)

    Andrade, Luana Machado; Sena, Edite Lago da Silva; Pinheiro, Gleide Magali Lemos; Meira, Edmeia Campos; Lira, Lais Santana Santos Pereira


    This paper is an integrative review analyzing the scientific production and legal documents regarding public policies for the elderly in Brazil. Research was conducted in the Virtual Health Library and Scopus databases, examining publications since 2003. Data were collected from June to September of 2011 using the following key words: "elderly" (idosos), "public policies" (políticas públicas), "elderly person" (pessoa idosa), "aging" (envelhecimento) and "civic participation" (participação cidadã). The search resulted in the selection of 15 articles and six legal documents targeted at the elderly in Brazil that were submitted to content analysis by categorization. The results revealed that aging in Brazil has occurred in the midst of adaptations entrenched in cultural biases, social, economic and educational discrepancies and the implementation of public welfare policies. There were few studies that indicated the importance of strengthening social movements that elicit discussion related to the elderly in Brazil. The conclusion reached is that the study will provide material for reflection about the construction of a new reality about aging in Brazil.

  12. A review on human attitudes towards reptiles in Brazil. (United States)

    Alves, Rômulo Romeu Nóbrega; Vieira, Kleber Silva; Santana, Gindomar Gomes; Vieira, Washington Luiz Silva; Almeida, Waltécio Oliveira; Souto, Wedson Medeiros Silva; Montenegro, Paulo Fernando Guedes Pereira; Pezzuti, Juarez Carlos Brito


    For many millennia humans and reptiles have interacted, but the attitude of humans towards these animals has depended on culture, environment, and personal experience. At least 719 reptile species are known to occur in Brazil and about 11% of this fauna has been exploited for many different purposes, including bushmeat, leather, ornamental and magic/religious uses, and as folk medicines. Brazil can therefore serve as an interesting case study for better understanding reptile use by human societies, and the present paper catalogues some of the reptile species being used in Brazil and discusses implications for their conservation. A literature review indicated that 81 reptile species are culturally important in this country, with 47 (58%) species having multiple uses, 54 being used for medicinal purposes, 38 as food, 28 for ornamental or decorative purposes, 20 used in magic/religious practices, 18 as pets, and 40 are commonly killed when they come into contact with humans. Regarding their conservation status, 30 (37.5%) are included on State's Red List, Brazilian Red List or the IUCN Red List. There are many forms of interaction between reptiles and humans in Brazil-although most of them are quite negative in terms of wildlife conservation-which reinforces the importance of understanding such uses and interactions in the context of protecting reptiles in Brazil. A better understanding of the cultural, social, and traditional roles of these reptiles is fundamental to establishing management plans for their sustainable use.

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

    Directory of Open Access Journals (Sweden)

    Catharina Leite Matos Soares


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

  14. Mesozoic dinosaurs from Brazil and their biogeographic implications. (United States)

    Bittencourt, Jonathas S; Langer, Max C


    The record of dinosaur body-fossils in the Brazilian Mesozoic is restricted to the Triassic of Rio Grande do Sul and Cretaceous of various parts of the country. This includes 21 named species, two of which were regarded as nomina dubia, and 19 consensually assigned to Dinosauria. Additional eight supraspecific taxa have been identified based on fragmentary specimens and numerous dinosaur footprints known in Brazil. In fact, most Brazilian specimens related to dinosaurs are composed of isolated teeth and vertebrae. Despite the increase of fieldwork during the last decade, there are still no dinosaur body-fossils of Jurassic age and the evidence of ornithischians in Brazil is very limited. Dinosaur faunas from this country are generally correlated with those from other parts of Gondwana throughout the Mesozoic. During the Late Triassic, there is a close correspondence to Argentina and other south-Pangaea areas. Mid-Cretaceous faunas of northeastern Brazil resemble those of coeval deposits of North Africa and Argentina. Southern hemisphere spinosaurids are restricted to Africa and Brazil, whereas abelisaurids are still unknown in the Early Cretaceous of the latter. Late Cretaceous dinosaur assemblages of south-central Brazil are endemic only to genus or, more conspicuously, to species level, sharing closely related taxa with Argentina, Madagascar, Indo-Pakistan and, to a lesser degree, continental Africa.

    Siniscalchi, Carina Renno


    In 2004, it was established the National Program for Production and Use of Biodiesel (PNPB) which encourages the participation of family farming in the biodiesel production chain, boosting rural development and social inclusion of these workers. From 2008 on, the PNPB decided that it would be mandatory the add 2% of biodiesel into diesel, named B2, and from 2010 on, the obligation of B5 was imposed. However, after two years of mandatory mixing, over 80% of the raw material for biodiesel production comes from large producers of soybeans in the Midwest. Thus, the focus of this study was to identify the main constraints and opportunities for family farming to participate in the program, based on the analysis of design parameters and guiding PNPB and the main stages of the agricultural seeds in the semi-arid. The study focused on Ceara as it is the state that greatly encourages the participation of small farmers through subsidies associated with the adoption of agro-ecological farming practices (author)

    The aim of this paper was analyze the relationship between economic and energetic indicators of corn crop in no tillage production system in familiar farmers at Pratania town in Sao Paulo state. It was collected data from two meanly farmers of this municipal district to compose the production systems of the corn crop. It was also collected data of the monthly average prices of corn, inputs and inflation rates, in the period of 2001 to 2005. The energetic results were presented by the structure of the energetic expenses by type, source and shape in Mega joules (MJ) unit and energetic and cultural efficiency indicators. The economic results were presented in the probability distribution of economic index, given by rate of monetary output and inputs, estimated by the gross income and operational costs, respectively. Both systems showed a dependence of industrial and fossil sources of energy, mainly chemical fertilizers and Diesel oil. For both systems, the economic efficiency indicator was lower than the cultural energetic efficiency indicators, considering the prices of harvest season (March and April). It was verified that economic and energetic efficiency indicators are not coincident and that efficient energetic systems may not be efficient from the economic view. (author)

    This article relates the development of a research about low cost for rural electrification projects, which have been used like a base to develop a technical analysis in whole projects of the program 'Luz para Todos'. This program was made in 2002 with the purpose to offer electricity for whole people in Brazilian rural area. This method was developed seeking in to achieve cost reduction in the planning made by electric companies in Sao Paulo state. At first, were analyzed the rural electric projects made by electricity companies in the program 'Luz da Terra', in front of to the commitment in achieving cost reduction in the rural electric projects. The program 'Luz da Terra' was made whit a social purpose and it was developed in the whole Sao Paulo state, during 1996 until 2004. One of the main demands to achieve reasonable costs and to allow the program's viability was the previous analyses of rural distribution projects, before them changing to work of electricity, checking out if they had well defined. social, technical and economics methods. For that, were chosen quantitative and non-quantitative indicators, agreement whit a comparative analysis of each company performance in the program 'Luz da Terra', in agreement whit historical series, based on the group of the final result of each distribution electricity project. In a second moment, the same methodology was adjusted to confront the plans data of each company's future works in the program 'Luz para Todos', using the results of the first program. The research allowed the identification of some planner's tendencies when developing from a more rigorous model of low cost, like was the program 'Luz da Terra', to the actual program 'Luz para Todos'. Applied to all companies in the Sao Paulo state, the study served as a support to renegotiate budgets, what provided savings of more than US$ 10,000.000 in a total of 42,000 connections. (author)

    With the increasing of energetic demand in several production sectors, the search for renewable energy sources which do not cause negative environmental impacts has become more and more relevant. Amongst all the important factors to decide for installing isolated generation systems as renewable sources or diesel and taking the distribution network to isolated communities, it should be considered the economic viability of those benefits. This study aimed to analyse the hybrid solar wind system installed in an isolated community, in Jalapao - TO. Three scenarios were analyzed: first of them, getting the capital back with MRI = 6% per year; second one, getting the capital back with MRI = 0; and third, without getting the investment back. In all the three cases, O and M costs were considered. The proceeds were calculated from the production at the communities workshop, in which the electricity was available. The results indicated that this technology is economically viable if the generated energy is used for production process. It also demonstrated that the third scenario is more interesting for the community, since the contribution per family is only 8% of its incomes. (author)

    The integration of all available geochemical data from this and adjoining blocks (BM-J-1 e BM-J-3) Jequitinhonha Basin revealed that only the Albian-Turonian and Aptian sections contains potential hydrocarbon source rock intervals. The existence of an oil accumulation (1-BAS-37) represents an unequivocal evidence of the presence of effective source rocks in the Jequitinhonha Basin. The geochemical characteristics of this oil accumulation points to an origin related to petroleum source rocks deposited under a lacustrine/marine restricted (hyper saline) environment. Such characteristics are typical of pre-salt Aptian source rocks in several basins along the Brazilian margin. The pseudo-3D modeling results indicate that the stage of thermal evolution of the base of the rift section attained ranges from early mature (0.6-0.8 Ro) in the structural highs to over mature (up to 2.0% Ro) in the structural lows On the other hand, the potential sources rocks of Albian-Turonian age ranges to immature to early mature throughout the block. The modeling results also points to the existence of two distinct hydrocarbon 'kitchens': one located in the easternmost portion of the block (slope/deep water area) and the other in a structural low located in the shallow platform area. The main phase of petroleum expulsion ranged from Late Cretaceous/Paleogene in the platform area. Probabilistic simulations has estimated migrated oils and gas volumes around 507 MMbbl and 20 billion cubic meters, respectively. (author)

    One of the main determinants to the expansion of natural gas on the Brazilian domestic market is its price. Hence, it is important to analyze the price competitiveness of natural gas vis-a-vis its competitors. The current paper focuses on the market of natural gas in vehicles (the compressed natural gas - CNG), and uses co-integration techniques to estimate the price-elasticity of CNG, the cross-elasticity of CNG and gasoline, and the income-elasticity. The results suggest that price is a relevant factor in the long-run, while in the short-run income is the most significant determinant of the demand variation. In addition, the paper also shows an imperfect substitutability between CNG and gasoline. (author)

    Two methods using headspace solid-phase microextraction and gas chromatography-mass spectrometry were developed for the determination of polycyclic aromatic hydrocarbons (PAH) and BTEX. Best results were obtained using DVB/CAR/PDMS fiber, with 10 min extraction at 25 Degree-Sign C and 0.15 min desorption at 260 Degree-Sign C (BTEX), and PDMS/DVB fiber, with 60 min extraction at 90 Degree-Sign C, 10% NaCl and 5 min desorption at 270 Degree-Sign C (PAH). LOD intervals were 3x10{sup -2} - 5x10{sup -2} {mu}g L{sup -1} (BTEX) and 1.6x10{sup -3} - 1.4 {mu}g L{sup -1} (PAH). The methods were applied to forty-five groundwater samples from monitoring wells of gas stations and only benzene level exceeded the limit established by Brazilian regulations. (author)

    This work has the objective to analyze the impact of the cost of from an ethane reformer / fuel cell in the family income considering the development of two productive activities selected by the community itself: the production and marketing of cassava flour and 'rapadura', a typical brazilian candy. The community energy demand was analyzed to achieve the results; estimated the energy cost from the implemented system and the money from the selling of the cassava flour and 'rapadura' produced with this electricity; the study of sensibility of the ethanol price in the electrical energy cost was done too, and the cassava flour and 'rapadura' in the family funds. From the results, it was verified that the electrical energy cost has a 16,4% impact in the family gross income and a net value around R$ 260,85/family, indicating that the community will have enough funds to pay for the energy and also will rise the amount of money for each family. Besides, the comparative analyze of the cost of the electricity from the ethanol/fuel cell reformer and photovoltaic systems shows that, considering only the maintenance and operation costs, the first one should be more attractive than the second one.

    The wind energy is an abundant source of renewable energy, clean and available almost everywhere. For its use, studies are needed to adequately describe its intensity for statistical methods and design for wind turbines. The objective is to structure the mathematical methods used to conduct a general description of the wind, to establish a description of the wind regime using the parameters described using the Weibull function and the analytical model of power from a wind turbine, as well as applications of these methods show. This work was developed at Rural Empowerment Lab of FCA/UNESP in Botucatu-SP. For the application of methods were utilized measurements of wind speed and direction, between 2004 and 2005, obtained by anemometer RM Young Wind Monitor-Campbell. As a result, they estimated the wind behavior and distribution of wind in the region, with 78 kWh of energy production, relatively low potential to supply a small house. Moreover, this energy could possibly be applied in ambient illumination, power supply for electric fences and irrigation of vegetables. (author)

  8. Evaluation removes obstacles to sterilization in Brazil. (United States)


    In 1978, Centro de Pesquisas de Assitencia Integrada a Mulher e a Crianca (CPAIMC) in Rio de Janeiro began to offer interval sterilizations in an attempt to increase the access of poor women to sterilization services. By the end of 1984, the program had provided in excess of 19,000 sterilizations, making CPAIMC Brazil's largest single source of voluntary interval sterilization. Despite the program's success, CPAIMC was concerned that obstacles still existed in the poor woman's path to sterilization access. A study was conducted by Family Health International (FHI) in collaboration with the Pathfinder Fund and CPAIMC's Department of Information, Evaluation and Research to locate possible barriers. The study indicated that less than half of the women who requested sterilization between June 1 and August 31, 1983 actually had the procedure. During that period, 1256 women requested sterilization at the CPAIMC clinic. Of these, 925 were approved, and 639 were scheduled for surgery. Only 559 were actually sterilized within 3 months of receiving approval. 1 possible reason why women were not receiving the surgery was that the women requesting sterilization actually were not highly motivated to obtain the service. Yet, study results indicate this probably was not the reason. During initial interviews at the clinic, many women said they had thought very carefully about being sterilized, and more than 40% reported deciding to have a tubal ligation before their last pregnancy. Almost 3/4 of the women reported that they did not plan their last pregnancy, and almost 2/3 indicated that the pregnancy was unwanted. About 63% were contracepting, and many were using effective methods. More than half of the non-contraceptors were not using a method because they had just ended a pregnancy and were not sexually active. As a group, the women requesting sterilization were highly motivated to avoid having more children. Age and number of children were the most important criteria used by

    Full Text Available One of the greatest problems observed in Brazilian urban watersheds are concerned to the amount of solid residues, domestic sewerage and sediments that are disposed in the rivers and streams that drain those areas. This project aims to present these problems through a study of case taken in an urban watershed in Porto Alegre city, Southern Brazil. For this study, different procedures were used, such as field surveys, interviews with the inhabitants, satellite images, sediment samples, flow measures and morphology assessment of part of the local fluvial system to check the degree of instability of the channel. In 2005, it was verified that 42.57% of the watershed was impermeable, considering the paved streets, the residential and commercial buildings and stone pavements. As there was no sewer treatment, most of this sewerage was directly disposed into the stream and the TOC has reached 20% (m/m. Moreover, the occupation of riparian areas, a great amount of soil exposed in the watershed, the nonpaved streets and a great volume of solid residues were causing the instability in the channel, silting the stream bed. The metals (Zn, Pb and Cr selected for this study are most frequently found in high concentrations in urban areas. The results suggest the occurrence of a high enrichment of the fluvial sediment by these metals. The concentrations of these elements vary temporally during storms due to the input of impervious area runoff containing high concentration of elements associated to vehicular traffic and other anthropogenic activities. Then, it is possible to conclude that the contamination of the urban watershed is reflected in the results obtained in the fluvial suspended sediments.

    de Carvalho, Isis Polianna Silva Ferreira; Peixoto, Henry Maia; Romero, Gustavo Adolfo Sierra; de Oliveira, Maria Regina Fernandes


    To estimate the Brazilian direct and indirect costs of human visceral leishmaniasis (VL) in 2014. Cost-of-illness study on the Brazilian public health system and societal perspective. VL cases registered in the Notifiable Diseases Information System in the year of 2014 were considered. Direct medical costs regarding diagnostic, treatment and care provided to patients with VL were estimated through the top-down approach. The indirect costs related to productivity loss due to premature mortality and morbidity were estimated by means of the human-capital method. In 2014, 9895 suspected cases of VL were reported in the Notifiable Diseases Information System, and 3453 were later confirmed. There were 234 patients with Leishmania-HIV coinfection underwent a secondary prophylaxis. The total cost of VL in Brazil was US$ 14 190 701.50 (US$ 14 189 150.10 to 14 199 940.53) that varied according to the sensitivity analysis. The total of direct medical costs corresponded to US$ 1 873 681.96 (US$1 872 130.55 to 1 882 920.99), and the majority of costs was associated with hospitalisation (40%), followed by treatment (22%), and secondary prophylaxis (18%). Productivity loss corresponded to US$ 11 421 683.37 for premature mortality and US$ 895 336.18 for work absence due to hospitalisation by the illness. VL represents an expensive health problem for the Brazilian public health system and society, mainly because of its productivity loss due to premature mortality. Interventions to reduce VL lethality could have a great impact on decreasing the cost of illness. © 2017 John Wiley & Sons Ltd.

  11. Acute fasciolosis in cattle in southern Brazil

    Directory of Open Access Journals (Sweden)

    Maria de Lourdes Adrien


    Full Text Available This study describes the epidemiological and pathological aspects of an outbreak of acute fasciolosis in cattle in southern Brazil. Fifteen out of 70 three-year-old pregnant cows lost weight in the 30-40 days prior to calving. Clinical signs included diarrhea, weakness, mild anemia and jaundice. Dark yellow fluid in the abdominal cavity was observed at necropsy. Fibrin and clotted blood were adhered to the pericardium and lung, primarily in the diaphragmatic lobes. The liver was enlarged, and the capsular surface was irregular with clear areas and petechiae. At the cut surface, the liver was irregular, firm and edematous, and several hemorrhagic channels could be observed. Areas of fibrosis through the parenchyma and whitish thrombi occluding the great vessels were also observed. The livers of 10 cows that not died were condemned at slaughter for lesions of fasciolosis similar to those observed at necropsy. Microscopically, the liver showed areas of coagulation necrosis, extensive hemorrhages in the streaks or foci and disruption of the parenchyma with neutrophil and eosinophil infiltration. Fibrosis and bile duct proliferation were also observed. Immature Fasciola hepatica flukes were observed in the parenchyma surrounded by degenerated hepatocytes, neutrophils, eosinophils, and hemorrhages. The outbreak occurred on a farm located in an area endemic for fasciolosis, although the acute form of the disease is not common in cattle in this region. It is likely that the cows were infected by F. hepatica metacercariae released in the late fall or early spring in the rice stubble where the herd was grazing prior to calving. Although mortality due to fasciolosis in cattle is infrequent, outbreaks can occur and treatments that are effective in both the immature and adult forms of the parasite should be administered to prevent economic losses.

  12. Hospital deaths and adverse events in Brazil

    Directory of Open Access Journals (Sweden)

    Pavão Ana Luiza B


    Full Text Available Abstract Background Adverse events are considered a major international problem related to the performance of health systems. Evaluating the occurrence of adverse events involves, as any other outcome measure, determining the extent to which the observed differences can be attributed to the patient's risk factors or to variations in the treatment process, and this in turn highlights the importance of measuring differences in the severity of the cases. The current study aims to evaluate the association between deaths and adverse events, adjusted according to patient risk factors. Methods The study is based on a random sample of 1103 patient charts from hospitalizations in the year 2003 in 3 teaching hospitals in the state of Rio de Janeiro, Brazil. The methodology involved a retrospective review of patient charts in two stages - screening phase and evaluation phase. Logistic regression was used to evaluate the relationship between hospital deaths and adverse events. Results The overall mortality rate was 8.5%, while the rate related to the occurrence of an adverse event was 2.9% (32/1103 and that related to preventable adverse events was 2.3% (25/1103. Among the 94 deaths analyzed, 34% were related to cases involving adverse events, and 26.6% of deaths occurred in cases whose adverse events were considered preventable. The models tested showed good discriminatory capacity. The unadjusted odds ratio (OR 11.43 and the odds ratio adjusted for patient risk factors (OR 8.23 between death and preventable adverse event were high. Conclusions Despite discussions in the literature regarding the limitations of evaluating preventable adverse events based on peer review, the results presented here emphasize that adverse events are not only prevalent, but are associated with serious harm and even death. These results also highlight the importance of risk adjustment and multivariate models in the study of adverse events.

  13. Changes in food consumption in Brazil. (United States)

    de Oliveira, S P


    Changes in eating habits have occurred in the last decades in several countries associated to demographic, economic, social and epidemiologic factors. In Brazil, the available data about food consumption are the result of Family Budget Surveys undertaken by Getúlio Vargas Foundation and IBGE (Brazilian Institute of Geography and Statistics) in 1961/1963 and 1987/88, respectively, and the National Study of Family Expenditure (ENDEF), carried out by IBGE during 1974/75. They reveal as principal tendencies the decreasing consumption of staple foodstuffs (beans, rice, manioc flour), pork meat, lard and butter, the replacement of bovine meat for chicken, and the increase in the consumption of eggs, milk products and vegetable oils. Based on these surveys, the intake of macronutrients in urban areas showed a decrease of carbohydrate and an increase of fat contribution as sources of calories, an increase in the consumption of animal protein in detriment of vegetable protein, and substitution of animal fats for vegetable fats. It was also observed an increase in the use of industrialized foodstuffs, directly related to income, leading to a greater diversity of foodstuffs and lower consumption of staple foods. Recent studies with adult and elderly population from the city of São Paulo show a reduction in the consumption of fatty and fried foods and sugar, and an increase in the consumption of fruits and vegetables because of health concern. Studies that take into account the verified changes in eating habits and the new consumption tendencies, as well as their impact on nutritional and health conditions of the Brazilian urban population, are presently needed.

  14. Breastfeeding on prime-time in Brazil. (United States)

    Castello Branco, H


    An example of the potential power of mass media in helping implement health programs, Brazil conducted a highly successful advertising campaign aimed at increasing the prevalence and duration of breastfeeding. The advertising campaign formed part of the 1981-84 breastfeeding program, which included -- among other things -- implementing maternity laws, establishing support groups for breastfeeding mothers, and disseminating information to policymakers. While several methods to inform parents had been tried, all had encountered resistance. An intensive mass media campaign changed all that. In 1982, 100 television channels began airing frequent, prime- time commercials -- an effort supplemented by radio sports, posters, and print advertisements. The airing of commercials followed extensive research and pretesting of the material, and were intended to help break down social barrier to breastfeeding, which included: women's fears that their breast size made then incapable of breastfeeding; employers' lack of support for working mothers; the lack of unity among doctors that breastfeeding is right for every child; and "machismo" -- men's attitude that the breast is only a sexual object. In order to establish a common goal, all spots ended with the slogan: "Breastfeeding -- 6 months that build up a life." And to establish credibility, the commercials featured well-known Brazilian celebrities. A spot aimed at facilitating the act for other women showed a popular actress breastfeeding her own child; another commercial showed a well- known singer and male role model asking fathers to support breastfeeding. An evaluation conducted in 1987 indicated significant positive changes due to the advertising campaign, demonstrating the potential of mass media in raising public awareness.

  15. The epidemiology of laryngeal cancer in Brazil

    Directory of Open Access Journals (Sweden)

    Victor Wünsch

    Full Text Available The city of São Paulo exhibits one of the highest incidences of laryngeal cancer in world and Brazil presents remarkable occurrence, compared with other Latin American countries. Around 8,000 new cases and 3,000 deaths by laryngeal cancer occur annually in the Brazilian population. In the city of São Paulo, incidence rates for laryngeal cancer among males have been decreasing since the late 1980s while, among females, the rates have shown a stable trend. This phenomenon is probably the expression of changes in gender behavior related to tobacco smoking. Several risk factors are involved in the genesis of laryngeal cancer. The most important are tobacco smoking and alcohol intake, but occupational hazards have also been associated with the disease, such as asbestos, strong inorganic acids, cement dust and free crystalline silica. Additionally, salted meat and total fat intake have been linked to elevated risk of laryngeal cancer. Conversely, several studies have confirmed that fruits, raw leaf vegetables and legumes protect against this cancer. Some researchers have postulated a possible association between laryngeal squamous cell carcinoma and human papilloma virus (HPV, but this is not universally accepted. Gastroesophageal reflux disease is weakly, but consistently correlated with laryngeal cancer. Familial cancer clusters, particularly of head and neck tumors, seem to increase the risk of laryngeal cancer. Some genetic polymorphisms, such as of genes that code for xenobiotic-metabolizing enzymes, have shown elevated risk for laryngeal cancer according to recent studies. Public health policies regarding the control of tobacco smoking and alcohol consumption, and also surveillance of carcinogen exposure in occupational settings, could have an impact on laryngeal cancer. No proposals for screening have been recommended for laryngeal cancer, but one diagnostic goal should be to avoid treatment delay when suspected symptoms have been observed.

  16. Chronic fatigue among bank workers in Brazil. (United States)

    de Fatima Marinho de Souza, M; Messing, K; Menezes, P R; Cho, H J


    The present study examines the prevalence of chronic fatigue (CF) among bank workers in Brazil and possible associations with gender and working conditions. The study sample included all 735 workers from the department of data processing of a state bank. CF was assessed using the Chalder Fatigue Scale. Working conditions and socio-demographic, socio-economic and psychosocial factors at work were analysed. Psychiatric symptoms were measured with the SRQ-20. The overall estimate of the prevalence of CF was 8.7% [95% confidence intervals (95% CI) = 6.4-10.9%]: 7.8% (95% CI = 5.5-10.7%) among men and 11.0% (95% CI = 6.7-16.9%) among women. The male-female difference was not statistically significant, even after adjusting for minor psychiatric disorders. The overall prevalence of CF without minor psychiatric disorders was 4.5% (95% CI = 2.7-6.3%): 3.9% (95% CI = 1.9-5.9%) among men and 6.4% (95% CI = 2.0-10.1%) among women. In the final model, risk factors for CF were fast work speed [odds ratio (OR) = 3.5], dissatisfaction at work (OR = 3.1), minor psychiatric disorders (OR = 6.8), and medium (OR = 1.8) and heavy domestic workload (OR = 12.0). CF is common among these bank workers and is associated with psychosocial factors at work. Particularly among women, domestic workload, marital status and the presence of young children were associated with CF in the stratified analysis. Domestic workload may add physical and mental stress, putting employees at risk for CF from overload, or CF may cause workers to perceive domestic work as heavy.

  17. Snakebites in Paraíba, Brazil

    Directory of Open Access Journals (Sweden)

    H. N. Albuquerque


    Full Text Available The epidemiological data on snakebites in the state of Paraíba, Brazil, is scarce. This accounts for the difficulties in helping the victims. Hence, to obtain the clinical and epidemic profile of the snakebite accidents in Paraíba, we studied the number of cases recorded in this state between January 1995 and December 2000. The data was collected from these sources: Center for Toxicological Assistance (Centro de Assistência Toxicológica - CEATOX and State Secretariat of Health (Secretaria Estadual de Saude, João Pessoa; 3rd Regional Health Center (3º Núcleo Regional de Saúde - NRS and the Division of Epidemiological Vigilance of the Municipal Secretariat of Health (Divisão de Vigilância Epidemiológica da Secretaria Municipal de Saúde - DVE/SMS, Campina Grande. The annual distribution of the snakebite incidence showed an irregularity and an increase in March, May and August; followed by a large reduction in November and December. It was also observed that snakebites occurred more frequently in the rural area, mainly among the male laborers between 10-49 years. In most cases, the bite occurred on the leg or foot. The interval between the snakebite and the medical assistance was less than six hours. The most common symptoms were pain, edema, erythema, and bleeding. The low lethality index and the high frequency of healing, without sequels, suggest that the treatment with serum neutralized the poison, indicating the efficacy of this treatment against snakebites by the specific species found in this region.

  13. Explaining Racial Disparities in Infant Health in Brazil (United States)

    Nyarko, Kwame A.; Lopez-Camelo, Jorge; Castilla, Eduardo E.


    Objectives. We sought to quantify how socioeconomic, health care, demographic, and geographic effects explain racial disparities in low birth weight (LBW) and preterm birth (PTB) rates in Brazil. Methods. We employed a sample of 8949 infants born between 1995 and 2009 in 15 cities and 7 provinces in Brazil. We focused on disparities in LBW (disparities. Results. The model explained 45% to 94% of LBW and 64% to 94% of PTB disparities between the African ancestry groups and European ancestry. Differences in prenatal care use and geographic location were the most important contributors, followed by socioeconomic differences. The model explained the majority of the disparities for mixed African ancestry and part of the disparity for African ancestry alone. Conclusions. Public policies to improve children’s health should target prenatal care and geographic location differences to reduce health disparities between infants of African and European ancestries in Brazil.

  14. Nematodes of elasmobranch fishes from the southern coast of Brazil

    Directory of Open Access Journals (Sweden)

    Marcelo Knoff


    Full Text Available New records for nematode species recovered from elasmobranch fishes in Brazil are established and new systematical arrangements proposed. Parascarophis sphyrnae Campana-Rouget, 1955 from the spiral valve of Sphyrna zygaena is referred for the first time in South America as a new host record. Procamallanus (S. pereirai Annereaux, 1946, from the spiral valve of Raja castelnaui is reported parasitizing an elasmobranch host. Nematode larvae of the genera Anisakis, Contracaecum, Pseudoterranova and Raphidascaris are listed from the stomach and spiral valves of several hosts. Anisakidae larvae previously referred in Brazil in the genus Phocanema should be reallocated in Pseudoterranova. Nematodes of the genera Anisakis, Contracaecum, Pseudoterranova and Raphidascaris are reported for the first time parasitizing elasmobranchs in Brazil.

  15. Medical and agricultural entomology in Brazil: a historical approach. (United States)

    Benchimol, J L


    Medical Entomology emerged in Brazil in the late nineteenth century, through the initiative of a group of physicians dedicated to researching microorganisms related to diseases of public health importance, especially yellow fever and malaria. They led the institutionalization of Bacteriology and Tropical Medicine in southeast Brazil and the sanitation of coastal cities and, subsequently, rural areas. Medical Entomology provided the professionals who would undertake campaigns against agricultural plagues, as well as the institutionalization of Agronomy and Veterinary Medicine. In the present article, I intend to show how relations between the professionals who gave life to Medical Entomology in Brazil were interwoven and to illustrate their relations with entomologists in other countries. I will also present an overview of the research problems faced by Brazilian entomologists at the turn of the nineteenth century and early decades of the twentieth.

  16. Teacher Training for Teaching Anthropology in Brazil and Argentina

    Directory of Open Access Journals (Sweden)

    Amurabi Oliveira


    Full Text Available Anthropology became systematized as a science in the nineteenth century, and its first teachers were self-taught, and it was initially only taught at a university level, although some countries had limited experiences with Anthropology in basic education. This article analyzes the education of anthropology teachers in Brazil and Argentina, considering the various institutional and academic settings in both countries. While Argentina has fewer courses than Brazil, these courses are more specific, and focused on the education of anthropology teachers. In Brazil anthropology is offered within social science courses in basic education, and specifically within sociology classes. This paper analyzes how teacher courses in Anthropology education in these two countries deal with the challenges in their different institutional and academic contexts.

    Abreu, Mirhelen Mendes de; Battisti, Raphael; Martins, Rachel Samhan; Baumgratz, Thiago Dias; Cuziol, Mirella


    There is no SDM in clinical practice in Brazil. The first steps have been taken towards research and tool development recently. Likewise, our society is starting to get involved with decision making in health care. This paper aims to offer an overview of the Brazilian health system history, its values, and its influence on SDM. The participative social control concept is introduced as a result of the movement against the dictatorship era. In addition, the influence of social changes on the Medical Ethical Code is delineated. SDM state of the art in Brazil is also discussed and the challenges to implement it on clinical practice are described. Regardless the challenges, it is possible to make a positive assessment of SDM in Brazil. 2011. Published by Elsevier GmbH.

  18. [Vaccination, smallpox, and a culture of immunization in Brazil]. (United States)

    Hochman, Gilberto


    The aim of this paper is to discuss the emergence and establishment of a "culture of immunization" in the contemporary Brazil from the eradication of smallpox. This culture is associated with a long process of introduction of vaccines, vaccination campaigns and mass vaccination undertaken by the Brazilian government since the late nineteenth century. Particular importance is attributed to the campaign to eradicate smallpox in Brazil (1966-1973). The experience of mass vaccination of the population against smallpox is contrasted with episodes of resistance as the "revolt against the vaccine", and regarded as crucial in shaping new policies and new understandings about the role of immunization in public health and its place in society Brazil.

  19. Regional Governance in Brazil's Unified Health System: a conceptual essay. (United States)

    Ribeiro, Patrícia Tavares; Tanaka, Oswaldo Yoshimi; Denis, Jean-Louis


    This article is a conceptual essay aimed at supporting analyses of the regionalization processes implemented in Brazil's Unified Health System, from the perspective of regional governance. The authors conducted a literature review in the social sciences, public administration, and critical geography, focusing on the concepts of governance, territorial governance, and regional governance in the debate on development. In dialogue with these contributions to the analysis of recent regulation and implementation of health sector regionalization in Brazil, with special reference to use of the Organizational Contract for Public Action (COAP) in the country's health regions, the article concludes that the research on governance as a modern approach to linking public policies highlights the timeliness of developing methodologies and critical reflection on the relevant national processes in Brazil for future health sector proposals, thereby pointing to a new stage in the improvement of the Unified Health System.

  20. Scale Insects (Hemiptera: Coccoidea) on Myrciaria dubia (Myrtaceae) in Brazil. (United States)

    Wolff, V R S; Kondo, T; Peronti, A L B G; Noronha, A C S


    Commercial cultivation of the fruit tree Myrciaria dubia (Myrtaceae) is being developed in Brazil but phytophagous insects, including scale insects (Hemiptera: Coccoidea), can become pests in plantations. The coccids Ceroplastes jamaicensis White, Coccus viridis (Green), Parasaissetia nigra (Nietner), Pseudokermes vitreus (Cockerell) (Coccidae), and the diaspidid Pseudaonidia trilobitiformis (Green) were collected on M. dubia in the municipality of Belém and Tomé-Açu, state of Pará (PA), metropolitan and Northeast Pará mesoregions, Brazil. A key to species of Coccoidea recorded on M. dubia, based on adult females, is provided. Photographs for all scale insects reported on M. dubia are provided. Ceroplastes jamaicensis is recorded for the first time for Brazil and is herein reported for the first time associated with this host.
