LDC nuclear power: Brazil

International Nuclear Information System (INIS)

Johnson, V.

1982-01-01

Brazil has been expanding its nuclear power since 1975, following the Bonn-Brasilia sales agreement and the 1974 denial of US enriched uranium, in an effort to develop an energy mix that will reduce dependence and vulnerability to a single energy source or supplier. An overview of the nuclear program goes on to describe domestic non-nuclear alternatives, none of which has an adequate base. The country's need for transfers of capital, technology, and raw materials raises questions about the advisability of an aggressive nuclear program in pursuit of great power status. 33 references

Seismic risk map for Southeastern Brazil

International Nuclear Information System (INIS)

Mioto, J.A.

1984-01-01

During the last few years, some studies regarding seismic risk were prepared for three regions of Brazil. They were carried on account of two basic interests: first, toward the seismic history and recurrence of Brazilian seismic events; second, in a way as to provide seismic parameters for the design and construction of hydro and nuclear power plants. The first seismic risk map prepared for the southeastern region was elaborated in 1979 by 6he Universidade de Brasilia (UnB-Brasilia Seismological Station). In 1981 another seismic risk map was completed on the basis of seismotectonic studies carried out for the design and construction of the Nuclear power plants of Itaorna Beach (Angra dos Reis, Rio de Janeiro) by IPT (Mining and Applied Geology Division). In Brazil, until 1984, seismic studies concerning hydro and nuclear power plants and other civil construction of larger size did not take into account the seismic events from the point of view of probabilities of seismic recurrences. Such analysis in design is more important than the choice of a level of intensity or magnitude, or adoption of a seismicity level ased on deterministic methods. In this way, some considerations were made, concerning the use of seisms in Brazilian designs of hydro and nuclear power plants, as far as seismic analysis is concerned, recently altered over the current seismic risk panorama.

Full Text Available The notification of sexually transmitted diseases (STD is a prime component of well-designed public health policy. However, peculiar aspects of STD must be taken into account for the correct management of surveillance activities. Here, we describe the distribution of the most common sexually transmitted diseases among patients attended by the gynecological clinics of the principal public hospitals of Brasilia and the Federal District, Brazilian capital, during six years. A total of 142,158 patients had their cervicovaginal samples collected for Papanicolaou preparations and eventual biopsies. Diagnosis was made according to cytological and histological alterations, distinguishing among vaginal infections, and pre-cancerous and cancerous cervical lesions. We also looked at the annual prevalence of the various types of infections and alterations. There was a high prevalence of bacterial vaginosis, trichomoniasis and candidiasis, with suggestive changes over the years. Pre-cancerous and cancerous lesions increased 2.2 fold during the six years. A large proportion of the cases involved late stages of cervical cancer, indicating the necessity of prompt attendance of the population in a routine gynecological prevention program.

The authors studied quality control procedures at human milk banks and nutritional profiles of 909 milk samples (from 195 donors, aged 15 to 45 years) from banked human milk (BHM) in Brasília, Brazil. Number of donations per donor ranged from 1 to > 10 that consisted mostly of mature milk (90.9%) with a mean total energy of 529 +/- 85 kcal/L and a mean total lipid of 22.7 g/L +/- 13.2. Microbiological quality (titrable acidity-Dornic, degrees D) was suitable for infant feeding in 99.2% of samples (< 8 degrees D), ranging from 2 degrees D to 8 degrees D (mean 4.8 +/- 1.4 degrees D). Most BHM (98.1%) samples were dispensed to inpatient infants (1-7 days) diagnosed with respiratory distress (30.1%), prematurity (20.7%), metabolic distress (16.0%), jaundice (14.4%), bacterial infection (6.0%), pneumonia (3.3%), congenital cardiac distress (2.2%), or other conditions (6.2%). Well-motivated mothers and trained staff are serving and sustaining an important life-saving network with long-lasting impact on public health.

1998-01-01

The development of Health Information Systems is widely determined by the establishment of the underlying information models. An Object-Oriented Matrix Model (OOMM) is described which target is to facilitate the integration of the overall health system. The model is based on information modules named micro-databases that are structured in a three-dimensional network: planning, health structures and information systems. The modelling tool has been developed as a layer on top of a relational database system. A visual browser facilitates the development and maintenance of the information model. The modelling approach has been applied to the Brasilia University Hospital since 1991. The extension of the modelling approach to the Brasilia regional health system is considered.

Two hundred and seventy-two sedentary women with a mean age of 66.75 ± 5.38 years were recruited for participation in this study. Obesity was determined by both body mass index and dual-energy X-ray absorptiometry (DXA evaluations. Sarcopenic obesity diagnosis was established from the ratio between fat-free mass and body surface area as obtained by DXA. There was no association of obesity with sarcopenic obesity (P = 0.424. In contrast, sarcopenia was significantly related to sarcopenic obesity (P < 0.001, although most of the elderly women with sarcopenia (n = 171 did not exhibit sarcopenic obesity. These results highlight the importance of diagnosing sarcopenic obesity as elderly women exhibiting sarcopenia could be either eutrophic or obese.Keywords: sarcopenic obesity, aging, obesity, sarcopenia, health

The U-Pb geochronological method using LAM-MC-ICPMS represents an important tool to investigate the geological evolution of sedimentary basins, as well as its geochronology, through the determination of upper limits for the depositional ages of detrital sedimentary rocks. The method has been applied in the Geochronology Laboratory of the Universidade de Brasilia, and in this study, a brief review of the provenance data for the sediments of the Neoproterozoic Brasilia Belt is presented and their significance for the evolution of the orogen is discussed. The results indicate that the Paranoa and Canastra Groups represent passive margin sequences formed along the western margin of the Sao Francisco-Congo continent. The Vazante Group presents similar provenance patterns, although Sm-Nd isotopic results suggest that its upper portions had contributions from younger (Neoproterozoic) sources, possibly from the Neoproterozoic Goias Magmatic Arc. On the other hand, metasediments of the Araxa and Ibia groups contain an important proportion of material derived from Neoproterozoic sources, demonstrating that they represent syn-orogenic basins. The provenance pattern of the Bambui Group is marked by an important Neoproterozoic component, showing that it constitutes a sedimentary sequence which is younger than 600 Ma, representing a foreland basin to the Brasilia Belt.

Southern Brasilia Belt (SE Brazil): tectonic discontinuities, K-Ar data and evolution during the Neoproterozoic Brasiliano orogeny

International Nuclear Information System (INIS)

Valeriano, Claudio Morrison de; Teixeira, Wilson; Simoes, Luiz Sergio Amarante; Heilbron, Monica

2000-01-01

This paper focuses the tectonic evolution of the southern brasilia belt, with emphasis on the Furnas segment, along the 21 deg C S parallel. The uppermost structural unit (Passos Nappe - PN) comprises a highly deformed metasedimentary succession interpreted as a fragment of the Neoproterozoic passive margin of western Sao francisco craton. An inverted metamorphic gradient ranging from greensvhits to lower granulite facies of medium to high-pressure regime characterizes the PN as relict of a subduction zone. The External Domain display a complex imbrication of basement rocks (Archean Piumhi greenstones, a turbiditic gaywacke succession and a calc-alkaline granitoid suite) with undated siliciclast low-grade metasedimentary rocks. The Sao Francisco Craton (SFC) comprises pre-1.8 Ga basement rocks covered by anchimetamorphic Neoproterozoic carbonatic shallow marine platform deposits of the Bambui group. The Brasiliano thrust stacking generated a coarse clastic influx of molassic character on the foreland zone of Sao Francisco Craton, coeval with the exhumation of the External Domain thrust sheets. New K-Ar determinations on mineral separates are presented an interpreted among previous data. The SFC basement rocks display Paleo-to Meesoproterozoic cooling ages. The allochthonous units, in contrast, display K-Ar ages within the 560-675 Ma range. Brasiliano thrust stacking is therefore interpreted to have taken place onto a cold Sao Francisco craton foreland, in a thin-skinned style, as basement rocks were not heated enough to have their-K-ar systems reset during the allochthony.

This study reviews the geological characteristics and puts forward a new evolution model for the Araxa Group in its type-area, the southern segment of the Neo proterozoic Brasilia Belt, Minas Gerais, Brazil. The Araxa Group is confined within a thrust sheet belonging to a syn formal regional fold, the Araxa Syn form, overlying two other thrust sheets made of the Ibia and Canastra Groups. The Araxa Group is described as a tectono stratigraphic terrane in the sense of Howell (1993). It comprises an igneous mafic sequence, with fine and coarse grained amphibolites, associated with pelitic meta sedimentary rocks, and subordinate psanmites. All rocks were metamorphosed to amphibolite facies at ca. 630 Ma ago and were intruded by collisional granites. The amphibolites represent original basaltic and gabbroic rocks, with minor ultramafic (serpentinite/ amphibole-talc schist). The basalts are similar to high Fe O tholeiites, with REE signatures that resemble E-MORB and {epsilon}{sub Nd(T)} =+ 1.1. The meta sedimentary rocks are interpreted as the result of a marine deep-water sedimentation. They have Sm-Nd model ages of 1,9 Ga, and {epsilon}{sub Nd(T)} = -10.21. The amphibolites and metasediments could represent a fragment of back-arc oceanic crust. The data presented here differ significantly from the original definition of Barbosa et al. (1970) who describe the Araxa Group as a pelitic/psanmitic sequence and the collisional granites as a basement complex. (author)

Full Text Available RESUMO: A Mecânica dos Sólidos, a partir de hipóteses simplificadoras, fornece modelos de cálculo que podem ser aplicados a vários problemas estruturais e estabelece as bases e o entendimento para o desenvolvimento de teorias e a construção de modelos mais complexos. Entretanto, dentro deste contexto, é comum desprezar as incertezas inerentes às propriedades dos materiais envolvidos, às condições de contorno e à geometria do problema. Neste artigo, ferramentas da Teoria da Confiabilidade Estrutural são aplicadas a problemas estruturais baseados na Mecânica dos Sólidos no intuito de analisá-los considerando algumas das incertezas envolvidas. Para isso, o método de Simulação de Monte Carlo é empregado na análise de confiabilidade de duas vigas. No estudo da primeira estrutura, busca-se investigar a influência da correlação entre variáveis aleatórias na probabilidade de falha do elemento estrutural. Na segunda estrutura, analisa-se o efeito da utilização de materiais com diferentes comportamentos (frágeis ou dúcteis e, consequentemente, diferentes critérios de ruptura, sobre a probabilidade de falha estimada. Verifica-se que as análises de confiabilidade estrutural podem fornecer muitas informações que estão fora do escopo das soluções determinísticas. Tais informações permitem uma avaliação mais precisa da segurança estrutural e podem também levar a um melhor entendimento do modelo estrutural em questão.

Full Text Available Promover o desenvolvimento de novas empresas tem sido um campo vasto de pesquisa. Observa-se que a iniciativa perpassa diversos setores da economia, iniciando-se pelo empreendedor, mas alcançando apoio do governo, órgãos de fomento, universidades e incubadoras de empresas. Há atualmente uma rede de organizações, dentre as quais ANPROTEC e o Sebrae que, juntamente com as incubadoras, tem procurado criar um ambiente em que novas empresas surjam e se desenvolvam, em que o conhecimento e o capital intelectual sejam potencializados. Nesse sentido, o objetivo geral dessa pesquisa foi analisar a influência do capital estrutural no sucesso de startups incubadas. A criação de startups tem sido cada vez mais reconhecida como um importante elemento para o desenvolvimento econômico brasileiro. Já o capital estrutural é um dos componentes do capital intelectual e possui como exemplos a infraestrutura física e tecnológica de uma empresa.

In South America, the epidemiology and ecology of dengue fever are strongly associated with human habits because the vector Aedes aegypti is strictly urban. Thus, the evaluation of people's knowledge and practice (PKP) is of great importance to improve integrated control measures. A PKP evaluation has been done in a suburb of Brasilia. Thirty questions were submitted to 130 habitants about income level, education, sources of information, specific knowledge about dengue, vector biology, and control measures applied. Other questions were about the responsibility of dengue control and the opportunity of applying a fine to people who would not cooperate with the control measures. Level of PKP was fairly high, either for housekeepers, workers, or students. The mosquito bite was cited as source of infection by 60.8% of interviewed people but 22.3% had no knowledge about this topic. The most cited symptoms in association with dengue were fever (73.1%), headache (66.2%), and rash (35.4%). Knowledge about mosquito biology and control was also fairly accurate, as demonstrated by 96.9% of answers. Elimination of water containers was the most efficient means according to 73% of people. Such action should be done mainly by the citizen (75.3% of answers). Despite the good PKP, correlations existed only between the PKP about vector biology and presence of potential breeding containers in March, and between the PKP about the disease and potential breeding containers in April. In conclusion, global educational campaigns may have a real impact on the PKP but this did not result in effective control of the mosquito breeding containers by the people.

Full Text Available From September to November 2005, the NASA Living with a Star program supported the Spread-F Experiment campaign (SpreadFEx in Brazil to study the effects of convectively generated gravity waves on the ionosphere and their role in seeding Rayleigh-Taylor instabilities, and associated equatorial plasma bubbles. Several US and Brazilian institutes deployed a broad range of instruments (all-sky imagers, digisondes, photometers, meteor/VHF radars, GPS receivers covering a large area of Brazil. The campaign was divided in two observational phases centered on the September and October new moon periods. During these periods, an Utah State University (USU all-sky CCD imager operated at São João d'Aliança (14.8° S, 47.6° W, near Brasilia, and a Brazilian all-sky CCD imager located at Cariri (7.4° S, 36° W, observed simultaneously the evolution of the ionospheric bubbles in the OI (630 nm emission and the mesospheric gravity wave field. The two sites had approximately the same magnetic latitude (9–10° S but were separated in longitude by ~1500 km.

Plasma bubbles were observed on every clear night (17 from Brasilia and 19 from Cariri, with 8 coincident nights. These joint datasets provided important information for characterizing the ionospheric depletions during the campaign and to perform a novel longitudinal investigation of their variability. Measurements of the drift velocities at both sites are in good agreement with previous studies, however, the overlapping fields of view revealed significant differences in the occurrence and structure of the plasma bubbles, providing new evidence for localized generation. This paper summarizes the observed bubble characteristics important for related investigations of their seeding mechanisms associated with gravity wave activity.

Educative strategies need to be adopted to encourage the consumption of healthy foods and to promote physical activity in childhood and adolescence. The effects of recreational physical activity and a health-habit orientation program using an illustrated diary on the cardiovascular risk profile of overweight and obese children was investigated. The weight and height of 314 schoolchildren aged between 9 and 11 years old, in a public school in Brasilia, Federal District, Brazil, were recorded. According to the body mass index (BMI) classification proposed by the World Health Organization, 84 were overweight or obese for their age and sex. Of these children, 34 (40%) participated in the study. Students were divided into two groups matched for sex, age, BMI, percent body fat (%BF): the intervention group (IG, n = 17) and the control group (CG, n = 17). The IG underwent a program of 10 weeks of exercise with recreational activities and health-habit orientation using an illustrated diary of habits, while no such interventions were used with the CG during the study period. Before and after the intervention, the children's weight, height, BMI, %BF, waist circumference (WC), maximum oxygen intake (VO2max), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, glucose, eating habits, and physical activity level (PAL) were assessed. In analyzing the data, we used descriptive statistics and paired and unpaired t-tests, using a significance level of 0.05. For assessment of dietary habits, a questionnaire, contingency tables, and the chi-squared test were used, with motivated to change their poor eating habits and to increase their physical activity level.

The illegal entry of animal products (POA brought in international passenger baggage is a factor that makes up the risk assessment and that grows proportionally to the intensification of international transit passengers. They evaluated the data on seizures of animal products intercepted in international baggage passengers in Airport of Brasilia (AIB-PJK/SBBR between the years 2010 and 2012. The analysis of the dynamics of these seizures considered the POA category, origin, airline and months more frequently and also verified the correlation between these variables. According to retrospective analysis, nearly eight tons of POA were seized from 52 countries throughout the study period. The results showed Portugal (p <0.0001 as the source of passengers who had higher frequency and quantity of seizures, and, added to other European origins, totaled 84.3% of seizures. The months of July, August and September stood out for the highest number of seizures and greater movement of international passengers. The increase in the number of seizures accompanied by a rise in the percentage of inspected passengers (r=0.69, emphasizing the importance of airport surveillance. According to the calculation of relative risk, passengers from African and South American countries showed greater magnitude of risk to bring animal

Full Text Available This article intends, through a field research, to reconstruct the life trajectory of individuals that migrated to Brasilia in the past three years and are now homeless. It highlights, in the narratives of their daily lives, the use of alcohol as a socializing and disruptive factor in their trajectories within a set of typical vulnerabilities of this population. The nature of the migratory process, in the individual and social senses, is analyzed as a way of contextualizing the debate regarding the life trajectory of the migrant individual. The process of formation, construction, and maintenance of a social identity and biography is based on the idea of socialization, which refers to the conditions in which an individual forms and is formed by the different and continuous social references around them. The interviews conducted based on the listening of life stories (biographical method imply the construction of a set of theoretical and analytical development that discusses the issue of the importance of establishing and maintaining social and emotional ties and the role of alcohol in the daily lives of these individuals.

Existe uma série de fatos macroeconômicos que podem ajudar a explicar essa inércia, como a baixa taxa de investimento e a falta de ordenação dos preços-chave da economia (como taxas de juros e taxa de câmbio, mas a proposição aqui feita é que existe um problema microeconômico estrutural relevante: falta de aptidão tecnológica das empresas industriais brasileiras.

The Itapuranga alkali granite and Uruana quartz syenite are large K-rich E W-elongated intrusions, in the central part of the Neoproterozoic Brasilia Belt, central Brazil. They are associated with Pireneus lineaments, which cut the regional NNW-SSE structures of the southern part of the belt. SHRIMP and conventional U-Pb data for the Itapuranga and Uruana intrusions indicate crystallization ages of 624 {+-} 10 Ma and 618 {+-} Ma, respectively. Three zircon cores from the Itapuranga granite yielded U-Pb ages between 1.79 and 1.49 Ga. Sm-Nd T{sub DM} ages for both intrusions are 1.44 Ga and epsilon{sub Nd}(T) values are -5.1 and -5.7, suggesting the input of material derived from older (Paleo- to Mesoproterozoic) sialic crust in the origin of the parental magmas. Magma mixing structures indicate co-existence of mafic and felsic end-members. The felsic end-member of the intrusions is dominantly represented by crust-derived melts, formed in response to the invasion of Paleo/Mesoproterozoic sialic crust by alkali-rich mafic magmas at ca. 620 Ma. These intrusions are roughly contemporaneous with, or perhaps slightly younger than, the peak of regional metamorphism in the southern Brasilia Belt. Their emplacement along the Pireneus lineament suggest a syn-tectonic origin for them, most probably in transtensional settings along these faults. (author)

Three individuals of silver carp (Hypophthalmichthys molitrix) were collected biweekly from Paranoá Lake (DF, Brazil) for analysis of microcystin (MC) concentrations in their muscle and liver tissue. Analysis by high performance liquid chromatography and mass spectrometry revealed MC masses and fragmentation patterns that were identified as MC-LR (995.04 m/z), MC-LA (909.01 m/z) and an unknown MC (987.07 m/z). Concentrations were calculated as MC-LR equivalents using a calibration curve prepared with a standard of MC-LR. May/06 was the month with the highest MC-LR equivalent concentrations in muscle and liver (3.83 ± 2.78, and 12.94 ± 10.51 μg g(-1), respectively). Our results show that during the drought months (April-September), consumption of fish with these MC concentrations would result in exposure to MCs that greatly exceed the World Health Organization's recommended tolerable daily intake limit of 0.04 μg MC kg(-1) body weight.

The Latin American and Caribbean Seminar on Women's Health and Reproductive Rights was held in Brasilia on November 13-14, 1991. The seminar manifesto reproduced here cities the many ways in which women in the region are oppressed by poverty and social injustice, and points to Cuba as a country where health and reproductive rights are respected. Latin American has been oppressed for 500 years. Its population still experiences misery, poverty, and deprivation of human rights and an equitable quality of life. The poor, especially women and children, are being decimated by endemic disease, mass sterilization, sexual and racial discrimination, and expropriation of liberty and the freedom to make choices concerning their own countries and bodies. The situation has resulted from the neoliberal policies of the latin American governments with the exception of Cuba. The international policy has called for renunciation of national sovereignty and submission to imperialist policy. social programs have suffered particularly. Women in Latin American are not considered 1st class in all stages of their lives. The Seminar of Women's Health and Reproductive Rights signals the urgent need to improve the situation through measures to mobilize society in defence of health and reproductive rights. High indices of maternal mortality caused largely by illegal abortion, premature births and perinatal deaths, lack of prenatal care, malnutrition, generalized violence, prostitution of minors and adolescents, psychic disturbances from limitations and deformations in the exercise of sexuality, lack of choice of contraceptive methods, surgical sterilization at a young age, excess numbers of cesareans, high-technology medical interventions motivated by economic interest, lack of sex education, and shortcomings of preventive health policies and basic public services are among the problems affecting Latin American women. Cuba is hailed as a country where women can freely choose abortion, and where

The chemical and spectrometric procedures of the U-Pb geochronology method on monazites, recently installed in the LAGIR laboratory, are described in detail. In addition, preliminary results on monazite samples from the Brasilia and Ribeira belts are reported and discussed in the context of the regional geology. Several experiments for calibration of ion exchange chromatographic columns with the AG-1x8 resin, were performed with HCl, using dissolved natural monazite samples. The Pb blanks of reagents are ∼ 0.5 pg/g in acids and ∼1 pg/g in H{sub 2}O. The total Pb blanks in chemical procedures were below 22 pg. Preliminary results are presented from three case studies related to Brasiliano orogenic belts of SE-Brazil, which correlate very well with previous age determinations from literature: two sub-concordant grains from an Araxa Group quartzite (southern Brasilia belt) define a concordia age of 602.6 ±1.4 Ma; a -0.8% discordant grain from a quartzite of the Sao Fidelis Group (Costeiro Domain, central Ribeira belt) yielded a concordia age of 535.3 ± 2.4 Ma; two 0.4 % and 1.3 % discordant monazite grains from the post-collisional Itaoca Granite (Costeiro Domain, central Ribeira belt) define a concordia age of 476.4 ± 1.8 Ma.

To describe the incidence and mortality rates from colon and rectal cancer in Midwestern Brazil. Data for the incidence rates were obtained from the Population-Based Cancer Registry (PBCR) according to the available period. Mortality data were obtained from the Mortality Information System (SIM) for the period between 1996 and 2008. Incidence and mortality rates were calculated by gender and age groups. Mortality trends were analyzed by the Joinpoint software. The age-period-cohort effects were calculated by the R software. The incidence rates for colon cancer vary from 4.49 to 23.19/100,000, while mortality rates vary from 2.85 to 14.54/100,000. For rectal cancer, the incidence rates range from 1.25 to 11.18/100,000 and mortality rates range between 0.30 and 7.90/100,000. Colon cancer mortality trends showed an increase among males in Cuiabá, Campo Grande, and Goiania. For those aged under 50 years, the increased rate was 13.2% in Campo Grande. For those aged over 50 years, there was a significant increase in the mortality in all capitals. In Goiânia, rectal cancer mortality in males increased 7.3%. For females below 50 years of age in the city of Brasilia, there was an increase of 8.7%, while females over 50 years of age in Cuiaba showed an increase of 10%. There is limited data available on the incidence of colon and rectal cancer for the Midwest region of Brazil. Colon cancer mortality has generally increased for both genders, but similar data were not verified for rectal cancer. The findings presented herein demonstrate the necessity for organized screening programs for colon and rectal cancer in Midwestern Brazil.

Helena Arias Lara Leite

Full Text Available Resumo O Brasil carece de uma legislação sobre alvenaria estrutural em situação de incêndio. Por conta disso, o Corpo de Bombeiros do Estado de São Paulo (2011 recomenda que se faça esse dimensionamento de acordo com as recomendações do Eurocode 6 (2005 ou norma internacional similar. Com o intuito de subsidiar futuras discussões sobre uma normatização nacional, neste artigo são apresentados os procedimentos de dimensionamento da alvenaria estrutural em situação de incêndio em vigor nos Estados Unidos, na Europa e na Austrália. Ao final, sem deixar ao largo o questionamento da aplicabilidade dessas três normas à situação brasileira, por conta das diferenças de materiais utilizados tanto nos blocos quanto nos acabamentos, sugere-se mesclar o que há de interessante nesses três códigos internacionais, de forma gradativa, na elaboração de futura norma brasileira sobre o assunto.

This work aims to measure the reduction of Carbon Dioxide (CO2) emissions in atmosphere by replacing the modal urban bus by Light Rail Vehicle (VLT). In order to accomplish this objective, a case study in Brasilia, Federal District, in the stretch of VLT which passes on Via W-3 South was conducted. The Theory of Externalities that discusses the right to ownership of private and public goods and responsibilities about the positive and negative externalities caused by the agents and individuals of society was used to support the analyses. It was used the Top-Down method, which allowed the calculation the direct emissions of CO2. The values obtained on the reduction of CO2 emissions were converted into values of carbon credits as a way to economically measure such reductions. The results showed a significant reduction in CO2 emissions per year and consequent environmental benefit. (Author)

Desempenho estrutural de protótipo de alvenaria construída com blocos de terra crua estabilizada

Aluísio Braz Melo

Full Text Available Uma das dificuldades na difusão de tecnologias de construção não convencionais é a ausência de informações técnicas sobre os sistemas construtivos existentes. Exemplos de construção eco-eficiente, em pequena escala, feita com blocos de terra crua, desenvolvidos pelo Prof. Roberto Mattone, do Politecnico di Torino, Itália, podem ser encontrados no Brasil, Itália e Argentina. Estes blocos feitos com prensa manual apresentam intertravamentos entre si que melhoram a resistência e a rigidez da alvenaria. Testes em protótipos construídos com eles são necessários para atender as exigências técnicas e se obter credibilidade nas agências governamentais financiadoras. Este artigo apresenta resultados referentes a avaliação de desempenho estrutural de alvenaria (protótipo construído em escala real feita com blocos de terra crua estabilizada, mecânicamente por prensagem e químicamente por adição de cimento Portland. As avaliações de cargas de ocupação e impactos na alvenaria foram realizadas através de ensaios de impactos de corpo mole e de corpo duro, solicitações transmitidas por fechamentos bruscos de porta e solicitações de cargas provenientes de peças suspensas. A partir dos resultados pode-se afirmar que o protótipo apresentou desempenho satisfatório em relação à segurança estrutural. Destaca-se que os blocos avaliados tem grande potencial para reduzir o impacto ambiental das edificações.

Full Text Available Resumo Neste trabalho é estudado o processo de projeto baseado em desempenho por meio do desenvolvimento de modelos paramétricos e algorítmicos, integrando análise estrutural ao design para a geração de estruturas geométricas complexas, com base em parâmetros de produção e montagem. Essa metodologia baseia-se no Modelo Performativo, em que a forma é gerada utilizando-se critérios de desempenho. Nessa abordagem o desenvolvimento de estruturas complexas só é possível pela reversão do processo de concepção da forma, cuja geração está atrelada aos parâmetros de geometria, material e carregamento. Assim, o engenheiro estrutural não participa apenas da fase de avaliação, mas também das fases iniciais do processo, criando um processo de pesquisa e produção de conhecimento comum entre os arquitetos e engenheiros. Para investigar essa abordagem, neste artigo é feita a concepção da estrutura de uma torre de energia eólica.

The largest forest of the world, the Amazon, presents an interesting and very complex system mixing forests, various topographies, sites of deforestation, cities, and regions close and far from the coast, which influence the climatology of the region. This study was focused in the region of Belem which is considered the rainiest region in the eastern Amazon with precipitation around 2000 mm/year. Belem is the capital of Para state, which is located in northern Brazil, 2,146 kilometers from Brasilia with an area of about 1,059,458 km² and a population of 1,432,844 inhabitants with 26% of the area of the Brazilian Amazon and having 49% of its natural attractions, according to the Organization of American States. Shallow convection and deep convection are among the main components of the local energy balance. An analysis of the performance of the Jet Propulsion Laboratory /NASA model of shallow convection parameterization in a framework of the single column model (SCM) in relation to the cluster of cumulus clouds formed in the coastal region of the Amazon forest due to squall lines is provided. To achieve this purpose infrared images from the Geostationary Operational Environmental Satellite (GOES), visible images from the GOES-12/METEOSAT satellites, and data obtained by the "Cloud processes of the main precipitation systems in Brazil: A contribUtion to cloud resolVing modeling and to the GPM (GlobAl Precipitation Measurement)" - CHUVA - campaign, during the month of June of 2011, were used. Results demonstrated that the parameterizations performed well in the case where only a core of clouds was observed.

Full Text Available This study examined the effects of crossbreeding low genetic potential cows of Bos indicus origin characterized by Gyr crossed with Holstein-Friesian and Simmental bulls to produce animals in a low input dual purpose system. The farm is situated near Brasilia, in the savannah region of Brazil. The climate of the region is classified as Aw by Köppen. Data was available on 1580 calvings and completed lactations of cows with three genetic types: Gyr, Holstein-Friesian × Gyr and Simmental × Gyr. The bulls ran with the cows all year round and the diet comprised of pasture (mainly Brachiaria and Andropogon during the summer (rainy season and milled sugar cane with added urea during the winter (dry season. A mineral salt mixture was available ad libitum. Data was analysed using Statistical Analysis System. The results show that, under low input management conditions, the crossbred cows produce approximately twice the volume of milk per lactation, calve at a younger age and have a shorter open period, but there are no significant differences between crosses for growth rates of the calves or body condition of the cows. In this system, crossbred cows had production higher indices than zebu cattle. The best indices were found for cows calving in the rainy season (September to December and thinner cows (with body condition 3-5 on a scale of 9.

The caterpillars of Stenoma cathosiota Meyrick feed on Roupala montana Aubl. (Proteaceae) in the cerrado of the Distrito Federal, Brazil. They construct shelters by joining leaves of the plant where they feed and pupate. The caterpillars are parasitized by a wasp (Hymenoptera: Brachonidae), which emerges from the pupae. Caterpillar abundance and parasitism frequency were associated in an area of frequently burned cerrado (biennial fire) and in another area that burns sporadically (1987 and 1994). For S. cathosiota, the variation among years in a single area, with sporadic fires, was greater than the variation among areas with different fire regimes. Caterpillar abundance among years was significantly different in the area that burns sporadically (c{sup 2} = 24.06; df. = 1; P = 0.000). However, there were no significant differences on caterpillar abundance between areas for the same period (c{sup 2} 3.45; df. = 1; P = 0.063). Parasitism frequency was high, reaching 29% of the collected caterpillars, and did not differ among areas. The great temporal variation in abundance of lepidopteran caterpillars in the cerrado makes it difficult to determine the effects that fire exerts over this fauna. (author)

The impact of building-integrated photovoltaics on the energy demand of multi-family dwellings in Brazil

Ordenes, Martin; Marinoski, Deivis Luis; Braun, Priscila; Ruther, Ricardo

2007-01-01

Brazil faces a continuous increase of energy demand and a decrease of available resources to expand the generation system. Residential buildings are responsible for 23% of the national electricity demand. Thus, it is necessary to search for new energy sources to both diversify and complement the energy mix. Building-integrated photovoltaic (BIPV) is building momentum worldwide and can be an interesting alternative for Brazil due its solar radiation characteristics. This work analyses the potential of seven BIPV technologies implemented in a residential prototype simulated in three different cities in Brazil (Natal, Brasilia and Florianopolis). Simulations were performed using the software tool EnergyPlus to integrate PV power supply with building energy demand (domestic equipment and HVAC systems). The building model is a typical low-cost residential building for middle-class families, as massively constructed all over the country. Architectural input and heat gain schedules are defined from statistical data (Instituto Brasileiro de Geografia e Estatistica - Brazilian Institute for Geography and Statistics (IBGE) and Sistema de Informacoes de Posses de Eletrodomesticos e Habitos de Consumo - Consumer Habits and Appliance Ownership Information System (SIMPHA)). BIPV is considered in all opaque surfaces of the envelope. Results present an interesting potential for decentralized PV power supply even for vertical surfaces at low-latitude sites. In each facade, BIPV power supply can be directly linked to local climatic conditions. In general, for 30% of the year photovoltaic systems generate more energy than building demand, i.e., during this period it could be supplying the energy excess to the public electricity grid. Contrary to the common belief that vertical integration of PV is only suitable for high latitude countries, we show that there is a considerable amount of energy to be harvested from vertical facades at the sites investigated.

Civil society participation in the health system: the case of Brazil's Health Councils.

Martinez, Martha Gabriela; Kohler, Jillian Clare

2016-10-26

Brazil created Health Councils to bring together civil society groups, heath professionals, and government officials in the discussion of health policies and health system resource allocation. However, several studies have concluded that Health Councils are not very influential on healthcare policy. This study probes this issue further by providing a descriptive account of some of the challenges civil society face within Brazil's Health Councils. Forty semi-structured interviews with Health Council Members at the municipal, state and national levels were conducted in June and July of 2013 and May of 2014. The geographical location of the interviewees covered all five regions of Brazil (North, Northeast, Midwest, Southeast, South) for a total of 5 different municipal Health Councils, 8 different state Health Councils, and the national Health Council in Brasilia. Interview data was analyzed using a thematic approach. Health Councils are limited by a lack of legal authority, which limits their ability to hold the government accountable for its health service performance, and thus hinders their ability to fulfill their mandate. Equally important, their membership guidelines create a limited level of inclusivity that seems to benefit only well-organized civil society groups. There is a reported lack of support and recognition from the relevant government that negatively affects the degree to which Health Council deliberations are implemented. Other deficiencies include an insufficient amount of resources for Health Council operations, and a lack of training for Health Council members. Lastly, strong individual interests among Health Council members tend to influence how members participate in Health Council discussions. Brazil's Health Councils fall short in providing an effective forum through which civil society can actively participate in health policy and resource allocation decision-making processes. Restrictive membership guidelines, a lack of autonomy from the

Brazil to Join the European Southern Observatory

2010-12-01

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

Dentro dessas duas atividades principais estão contidas diversas subatividades que tiveram seu desempenho medido. O objetivo foi comparar o desempenho de produtividade das subatividades e também das atividades principais em cada um dos quatro pavimentos da edificação. O melhor índice produtivo, tanto na elevação da alvenaria como na montagem da laje foi obtido na execução do terceiro pavimento. Com base nos resultados foi possível perceber que planejamento da obra e a minimização de erros de projeto, além de sua fácil leitura são itens fundamentais para melhorar o desempenho da mão de obra, e que o layout e a logística do canteiro também impactam diretamente nos resultados, demonstrando a importância de um transporte eficiente de materiais para se evitar esforços desnecessários. Além dos itens citados as condições climáticas também exerceram influência sobre a obra, prejudicando o ritmo de trabalho na execução do quarto pavimento tipo.

Created as the Brazilian capital, in the central western part of Brazil, Brasilia is a definitive example of 20th century modernist urbanism. It was built in only four years, from 1956 to 1960, following the project of urban planner Lucio Costa and architect Oscar Niemeyer that intended that every element - from the layout of the residential and administrative districts (often compared to the shape of a bird in flight) to the symmetry of the buildings themselves - should be in harmony with the city's overall design. This description is from the World Heritage Centre, of Unesco, that nominated Brasilia as a Cultural Heritage Property in 1987. Most of the remarkable buildings designed Oscar Niemeyer, cited by Unesco, are around the Plaza of Three Powers, as the Planalto ("Plateau") Palace, the National Congress, the Supreme Court, the Cathedral, the National Theatre among others. Aside from the worldwide recognition of the architectonic value of these buildings, it is barely mentioned the expressive use of white marble as cladding. Very few are found in the literature about specification criteria, provenance, fixation method and conservation. According to Oscar Niemeyer Foundation, at this moment they know that the stone come from a supplier in the State of Rio de Janeiro. A preliminary research indicated that the marble used in most of Brasilia buildings are from the municipality of Italva, in the northwest of the State of Rio de Janeiro (DRM-RJ, 2012). In a study carried out by DRM-RJ, in 2003, it is mentioned two white marble commercialized as dimension stone in Italva: "Sparkling Marble" (SM) and "Italva White Marble" (IWM), respectively dolomite-calcite marble and dolomite marble. Their main characteristics are: bulk specific gravity: 2,792 kg/m3 (SM) and 2,852kg/m3 (IWM); water absorption: 0.08 % (SM) and 0.10 % (IWM); uniaxial compression strength: 84.3 MPa (SM) and 88.2 MPa (IWM); modulus of rupture: 9.92 MPa (SM) and 8.75 MPa (IWM); coefficient of linear

O objetivo desta pesquisa foi avaliar, em um Latossolo Vermelho eutroférrico no município de Jaboticabal, SP, os parâmetros físicos do solo como a estabilidade de agregados, a condutividade hidráulica e o índice "S". O delineamento experimental foi o inteiramente casualizado com parcelas subdivididas (quatro níveis de compactação e duas profundidades, com quatro repetições e uma área de mata nativa (MN como testemunha. Os tratamentos de compactação foram: C0= 0; C1= 2; C2= 4; e C3= 6 passadas de um trator de 11 Mg. Verificou-se que a MN apresentou elevada relação aos índices diâmetro médio geométrico (DMG e diâmetro médio ponderado (DMP, que constaram agregados maiores e mais estáveis em comparação aos demais tratamentos estudados. Foi obtido o valor de "S" de 0,036 e redução nos níveis mais compactados para 0,026, visto que a compactação reduziu o valor de "S", que atingiu o valor limitante (< 0,035, apesar da mineralogia oxídica do solo analisado.

Full Text Available Purpose – This paper focuses on the regulation of Uber at regional level (Sao Paulo and Brasilia, national level (European Member States and supranational level (The European Commission initiative, which are often too restrictive. Methodology/approach/design – This article analyses standards and literature on regulation, as well as the role of competition. Attention was specially drawn to the market failure theory for justifying regulation, advocated by Breyer, Ogus and Baldwin & Cave. Due to the fact that there will be an evaluation of the regulations in place, consequentialism, welfarism and Pareto are briefly mentioned. Findings – None of the current regulatory responses, at the exception to Sao Paulo and the initiative by the European Commission that are not based exclusively on market failure theory, are working. Indeed, Uber is still banned in various cities. In others, the regulatory burden is so high that it takes away any incentives that Uber created. Regulation is not the only exit to market failure, competition must play a role. Uber is based on deregulation of the market and to try to regulate such concept with conventional theories will only lead to failures and restrictions. Practical implications – This article discusses the possible improvements to the already existing regulations. Originality/value – This paper correlates the regulation of Uber in Brazil and in Europe, explaining the difficulties these regulations are creating for Uber.

Newer antimicrobial therapies based on novel molecules urgently need to be developed, and this includes the antimicrobial peptides. In spite of the potential of antimicrobial peptides, very few of them were able to be successfully developed into therapeutics. The major problems they present are molecule stability, toxicity in host cells, and production costs. A novel strategy to overcome these obstacles is conjugation to nanomaterial preparations. The antimicrobial activity of different types of nanoparticles has been previously demonstrated. Specifically, magnetic nanoparticles have been widely

Dr Brasilia and Mr. Nacala: the apparent duality behind the Brazilian state-capital nexus

TOMASO FERRANDO

2015-06-01

Full Text Available In August 2010 Brazil decided to limit foreign direct investments (FDIs in land, and attracted the attention of politicians as much as the fears of businessmen. However, few months before, in September 2009, it had concluded a trilateral agreement with Japan and Mozambique to implement agribusiness and contract farming on an area of ten million hectares in the Mozambican region of Nacala. In light of that, the paper analyses the apparent duality of the Brazilian politics, and concludes that, exactly like in the case of the novel by Robert Louis Stevenson, it is not a matter of pathology, but a voluntarily induced double personality which is strategic in positioning Brazil at the core of the global capitalist system.

Full Text Available Os jornais dos principais países desenvolvidos vivem uma crise frequentemente atribuída ao desenvolvimento das mídias digitais. Essa situação parece não se reproduzir nas maiores economias emergentes. O presente trabalho sustenta que, embora o surgimento e avanço dessas mídias tenham efetivamente afetado negativamente o desempenho das empresas jornalísticas, a crise em questão é estrutural e suas origens antecedem o surgimento das mídias digitais. A hipótese de que a situação dos países emergentes seja estruturalmente diversa é testada e, acredita-se, refutada por meio de uma analise comparativa da evolução recente do negócio jornal nos EUA e no Brasil.

We used a force platform, AccuSway Plus, where the tests were conducted under the experimental conditions: open base, eyes open (OBEO; open base, eyes closed (OBEC; closed base, eyes open (CBEO; closed base, eyes closed (CBEC. The body sway velocity (V of the center of pressure, the displacement in the anteroposterior direction (COPap and mediolateral (COPml of the center of pressure were the parameters to evaluate the postural control. For statistical analysis we used the nonparametric Mann–Whitney U test, with a significance level of 5%.Results: In comparisons of variables between the groups, the experimental group outperformed by at least 75% of the control group values. In terms of global trends, the experimental group shows higher values of body oscillations in all experimental conditions and variables evaluated. Children with hearing loss had poorer balance performance compared to the group of hearing. The inferential analysis revealed a statistically significant difference in the balance between deaf and hearing children in the OBEC experimental condition in relation to the COPml parameter (P = 0.04. There were no statistically significant differences in comparisons between the sexes when the groups were analyzed separately. The prevalence of unknown etiology

Andrés Batista Cheung

Full Text Available Resumo As pontes protendidas de madeira consistem em sistemas estruturais alternativos, mais leves do que as pontes tradicionais, e apresentam grande rigidez e facilidade de montagem. No Brasil a primeira ponte protendida de madeira foi projetada e construída sobre o Rio Monjolinho, em São Carlos, SP. A confiabilidade desse tipo de estrutura é um dos pontos de maior preocupação técnica, embora essa forma de avaliação ainda não seja utilizada em projetos de pontes de madeira. Este trabalho objetivou avaliar a confiabilidade estrutural do sistema laminado protendido de madeira da ponte projetada sobre o Rio Monjolinho, com foco especial na resistência à flexão e na perda de protensão do sistema, considerando-se para tanto um conjunto variado de trens-tipo. O tabuleiro foi avaliado como uma viga equivalente, baseado no comportamento de placa ortotrópica, e para verificar a segurança da ponte um estudo de confiabilidade foi realizado considerando ações reais obtidas por meio dos dados da concessionária Centrovias. Os resultados das análises de confiabilidade revelaram que a ponte protendida de madeira apresentou índices de confiabilidade compatíveis para a maioria dos carregamentos simulados do tráfego, embora para alguns tipos de caminhões a ponte tenha apresentado índices de confiabilidade abaixo do recomendado pelas normas internacionais.

Full Text Available Abstract This study evaluated the CO2eq emissions during the life cycle of two social housing projects in the city of Brasilia. A house of ceramic brick masonry was compared to a light steel framing one. The life cycle carbon emissions assessment (LCCO2A with a cradle-to-grave approach was used. The relation between the thermal performance of the wall systems and CO2eq emissions in the operational phase of the houses were evaluated using the DesignBuilder software. In addition, six scenarios composed of three CO2eq emission factors from the Brazilian electrical grid and two schedules of occupation of houses (full and part time were evaluated. The brick masonry house presented less CO2eq emissions than the light steel framing one. For both houses, the operational phase was the most significant regarding the total CO2eq emissions (50% to 70%, followed by the construction (20% to 30%, maintenance (11% to 20% and end-of-life (lower than 1% phases. The results also showed the importance of considering different CO2eq emission factors for the Brazilian context in the operational phase. Finally, based on the results obtained, design guidelines for low carbon social housing were proposed.

Além disso, foram confeccionados prismas com três blocos e miniprismas, com pedaços serrados de blocos, para avaliação da resistência à compressão, módulo de deformação e tensão de aderência. Os resultados mostraram que existe potencial para se empregarem retentores de água à base de éter de celulose para a confecção de argamassas de assentamento para alvenaria estrutural de blocos de concreto, haja vista que houve aumento da capacidade de retenção de água das argamassas e que o uso do referido produto não exerceu influência na resistência à compressão delas e na resistência à compressão dos prismas. Contudo, a resistência à compressão das juntas de assentamento, o módulo de elasticidade dos prismas e a resistência à aderência na flexão sofreram reduções significativas quando do emprego do éter de celulose.

Full Text Available A realização do presente estudo teve como objetivo principal investigar a organização estrutural do campo semântico conceitual da emoção em crianças em uma perspectiva êmica. Participaram desta pesquisa 247 crianças de escola pública e particular, com idades entre sete e 12 anos. Foram aplicadas as técnicas de associação livre de palavras (emoção e duas perguntas (freqüência das emoções e o que sabiam sobre emoção. Essa ultima questão apontou que a maioria das crianças respondia relacionando emoções a sentimento, a coisas que sentem no coração. Elas também traziam exemplos de acontecimentos positivos e negativos, citavam emoções específicas, principalmente as classificadas como primária, pelos teóricos da área. Na questão relativa à freqüência destas emoções em sua vida as crianças apontaram alegria, felicidade e tristeza como as emoções mais vivenciadas no seu dia a dia. Na associação livre, as emoções primárias apareceram de forma predominante, destacando-se em primeiro lugar a alegria, seguida da tristeza, felicidade, raiva, medo e amor respectivamente. Emoções mais elaboradas, consideradas secundárias, também foram encontradas como saudade, ódio, paz, ansiedade, etc. Para verificar a organização estrutural do campo semântico conceitual, as categorias produzidas através da associação livre foram analisadas também por meio da Análise da Estrutura de Similaridade (SSA. Em seguida, para verificar a relação entre a estrutura decorrente do campo semântico encontrado e as variáveis idade, sexo, e tipo de escola, os dados foram analisados através do método das "variáveis externas como pontos". Regressões múltiplas foram também computadas. Foi encontrado que o tipo de escola e, sobretudo, a idade desempenharam um papel relevante em influenciar de forma significativa a organização estrutural do campo semântico conceitual das emoções, que apresentou uma estrutura ordenada de

Full Text Available Resumo Um dos fatores a serem levados em conta no dimensionamento de elementos comprimidos é sua esbeltez. Até hoje no Brasil utiliza-se o conceito de esbeltez simplificado, no qual o comprimento de flambagem é determinado por uma altura efetiva (hef, e o raio de giração é substituído por um parâmetro chamado espessura efetiva (tef, para o cálculo de fator minorador de resistência. Outras normas de alvenaria estrutural, como as norte-americana, europeia e australiana, trazem também em sua formulação de cálculo da capacidade de carga de uma parede comprimida um fator redutor de resistência. Já a normalização canadense indica que seja feita uma análise mais próxima da realidade, considerando o equilíbrio na configuração deformada da parede (análise P-Delta. Um programa experimental que envolveu 18 ensaios de paredes de blocos cerâmicos e de concreto com elevada esbeltez, obtida com a utilização de blocos de pequena espessura, é aqui relatado. As previsões da capacidade de carga para o caso de blocos de concreto de geometria vazada foram próximas aos resultados dos ensaios. No caso dos blocos cerâmicos utilizados, de geometria complexa, com as paredes dos blocos também vazadas, apenas a aproximação da norma canadense permitiu obter com algum grau de segurança e proximidade os resultados dos ensaios. Paredes mais esbeltas e com blocos de geometrias complexas exigem procedimentos mais refinados para o cálculo, em que o processo P-Delta e a verificação da seção com material não resistente à tração podem ser uma solução.

Seismic characteristics of central Brazil crust and upper mantle: A deep seismic refraction study

Science.gov (United States)

Soares, J.E.; Berrocal, J.; Fuck, R.A.; Mooney, W.D.; Ventura, D.B.R.

2006-01-01

A two-dimensional model of the Brazilian central crust and upper mantle was obtained from the traveltime interpretation of deep seismic refraction data from the Porangatu and Cavalcante lines, each approximately 300 km long. When the lines were deployed, they overlapped by 50 km, forming an E-W transect approximately 530 km long across the Tocantins Province and western Sa??o Francisco Craton. The Tocantins Province formed during the Neoproterozoic when the Sa??o Francisco, the Paranapanema, and the Amazon cratons collided, following the subduction of the former Goia??s ocean basin. Average crustal VP and VP/VS ratios, Moho topography, and lateral discontinuities within crustal layers suggest that the crust beneath central Brazil can be associated with major geological domains recognized at the surface. The Moho is an irregular interface, between 36 and 44 km deep, that shows evidences of first-order tectonic structures. The 8.05 and 8.23 km s-1 P wave velocities identify the upper mantle beneath the Porangatu and Cavalcante lines, respectively. The observed seismic features allow for the identification of (1) the crust has largely felsic composition in the studied region, (2) the absence of the mafic-ultramafic root beneath the Goia??s magmatic arc, and (3) block tectonics in the foreland fold-and-thrust belt of the northern Brasi??lia Belt during the Neoproterozoic. Seismic data also suggested that the Bouguer gravimetric discontinuities are mainly compensated by differences in mass distribution within the lithospheric mantle. Finally, the Goia??s-Tocantins seismic belt can be interpreted as a natural seismic alignment related to the Neoproterozoic mantle domain. Copyright 2006 by the American Geophysical Union.

Full Text Available Resumo Este trabalho teve como objetivo caracterizar o sedimento proveniente de dragagem de canais pluviais (SCP, do município de Salvador-BA, visando sua máxima substituição pela argila em cerâmica estrutural, uma vez que essa mistura binária faz parte do projeto piloto da massa padrão, na pesquisa da formulação de blocos intertravados cerâmicos. Inicialmente o sedimento foi submetido aos ensaios de índice de plasticidade, analise química por fluorescência de raios X, análise mineralógica por difração de raios X, analise térmica e granulométrica. A morfologia do material foi analisada utilizando-se microscopia eletrônica de varredura, acompanhada de espectroscopia de energia dispersiva. Em seguida foram feitas adições de sedimento (SCP a uma argila do município de Candeias-BA, nas proporções de 10, 20, 30 e 40% em massa. Foram preparados corpos de prova por prensagem uniaxial nas dimensões 60 mm x 20 mm, com pressão de compactação de 25 MPa, sendo que o material foi umidificado com 8% de água. A queima foi realizada em forno resistivo a 850, 950 e 1050 °C, com taxa de aquecimento de 5 °C/min. As propriedades avaliadas foram retração linear, absorção de água e módulo de ruptura à flexão. Os resultados indicaram que é possível a utilização do SCP em cerâmica estrutural, mediante os pré-requisitos exigidos em normas, na fabricação de telhas, blocos de vedação e tijolos.

Full Text Available A liofilização é o método mais comumente utilizado para a preparação de proteínas desidratadas, as quais devem apresentar estabilidade adequada por longo período de armazenagem em temperaturas ambientes. Entretanto, estudos recentes com espectroscopia no infravermelho têm documentado que os problemas relacionados com o congelamento e a desidratação induzidos pela liofilização podem levar ao desdobramento molecular da proteína. Através de análises por espectroscopia Raman, associadas com análise térmica por calorimetria exploratória diferencial (DSC, estudou-se a influência da taxa de congelamento no comportamento físico-químico e estrutural da albumina sérica bovina submetida ao processo de liofilização. Observou-se que a albumina liofilizada com taxa de congelamento de 2,5 °C/min apresentou maior alteração estrutural quando comparada à albumina liofilizada com taxa de congelamento de 30 °C/min, a qual apresentou menores oscilações espectrais nas regiões da amida I, III e pontes de dissulfeto, favorecendo a manutenção da conformação estrutural da proteína.Lyophilization (freeze-drying is the most commonly method used to prepare dehydrated proteins, which should have the desired long-term stability at ambient temperatures. However, recent infrared spectroscopic studies have documented that the acute freezing and dehydration stresses of lyophilization can induce protein unfolding. Through Raman spectroscopy associated with thermal analysis using differential scanning calorimetry (DSC, it was studied the influence of cooling rate on the structural and phase changes during lyophilization of bovine serum albumin. It was observed that bovine serum albumin (BSA lyophilized under slow freezing (2.5 ºC/min presented higher structure damage than the BSA lyophilized under fast freezing (30 ºC/min However, the lyophilization process using cooling rate of 30 ºC/min presented fewer spectra alterations on the Amide I

Full Text Available Alberto Moravia arrived in Brazil in the summer of 1960 to preside the Congress of the PEN Club. He had recently finished La noia, his eleventh novel, the one that most directly is connected to his first novel, Gli indifferenti (1929, and it marks a decisive turning point in his artistic, intellectual, and human course. The essay reconstructs the life and work of the 50-year-old writer, in which a 10-year research is summarized and concluded, opening a new phase. Rereading the articles written for Il Corriere della Sera and the review of the Quarto de despejo by Carolina de Jesus, we focused on the origin and acute reflection of Moravia about Brazil in those years (Brasilia, Bahia, Rio, between past and future. The experience of Brazil, for the writer, who in those following years will attempt new paths in the intellectual and literary field, and new goals for his travels, always more oriented, in the company of Dacia Maraini and Pier Paolo Pasolini, toward the Third World.

Full Text Available Streptococcus pyogenes, also known as group A Streptococcus (GAS, is a human pathogen that causes diverse human diseases including streptococcal toxic shock syndrome (STSS. A GAS outbreak occurred in Brasilia, Brazil, during the second half of the year 2011, causing 26 deaths. Whole genome sequencing was performed using Illumina platform. The sequences were assembled and genes were predicted for comparative analysis with emm type 1 strains: MGAS5005 and M1 GAS. Genomics comparison revealed one of the invasive strains that differ from others isolates and from emm 1 reference genomes. Also, the new invasive strain showed differences in the content of virulence factors compared to other isolated in the same outbreak. The evolution of contemporary GAS strains is strongly associated with horizontal gene transfer. This is the first genomic study of a Streptococcal emm 1 outbreak in Brazil, and revealed the rapid bacterial evolution leading to new clones. The emergence of new invasive strains can be a consequence of the injudicious use of antibiotics in Brazil during the past decades.

Structural control over well productivity in the Jundiaí River Catchment, Southeastern Brazil

Full Text Available The well productivity in crystalline terrains is extremely changeable and depends on external factors, in addition to the intrinsic properties of rocks. In the Jundiaí River Catchment, Southeastern Brazil, the main factor that influences well productivity is the existence of open discontinuities permeability in geologic environments that favor groundwater recharge. In that area, Pre-Cambrian shear and fault zones were reactivated throughout geologic time, controlling the morphostructural compartments and the Cenozoic sedimentary deposition. Superposition of productivity data and structural maps showed that more productive wells are concentrated mainly along the regional geologic structures. The structural control over well productivity is also noticeable in detailed scale. Using fine scale maps we show that the most productive wells are located in areas where brittle structures with NW-SE and E-W directions denote the action of neotectonic transtensional stress. The comprehension of evolutionary geologic history allied to fracturing analysis proved to be an efficient and a low cost technique, which is adequate for selecting areas for further developments using more expensive methods.A produtividade dos poços tubulares profundos em terrenos cristalinos é extremamente variável e depende, além das propriedades intrínsecas da rocha, de fatores externos a ela. Na bacia do rio Jundiaí, Região Sudeste do Brasil, a existência de descontinuidades abertas em situações geológicas favoráveis à recarga constitui o principal fator que influencia a produtividade dos poços. Nesta área, zonas de cisalhamento e zonas de falhas pré-cambrianas reativadas ao longo do tempo geológico controlam a compartimentação morfoestrutural e a deposição de sedimentos cenozóicos. O cruzamento do mapa estrutural com os dados dos poços que explotam o Sistema Aqüífero Cristalino mostrou que poços com produtividade elevada em relação aos demais concentram

Crustal structural survey for the state of Minas Gerais, Brazil, utilizing geophysical and geological information

Gravity, Magnetic (airborne, Magnet and Magsat), heat flow and seismicity available data for the state of Minas Gerais and adjacent regions is here analyzed, discussed and integrated with geologic information. The Late Archean crustal structure is defined as blocks of granite-greenstone separated by belts of high-grade terrains. The belts in eastern and southern Minas Gerais represent the lower parts of the Vitoria, Sao Paulo and Parana Blocks, which were up thrusted over the Brasilia Block through low-angle ductile simple shear Zones. That regional structure is cut and somewhat displaced by NW, ENE, NE and Ns fault sets. These faults are mostly related to the Transamazonian Event, and their geological expression appears to be as high-angle ductile simple shear zones. The development of the Middle/upper proterozoic folded sequences, the incidence of the Brasiliano/Uruacuano thermo tectonic events and the geometry of the Sao Francisco Craton were highly influenced by the preexistent weakness zones. The high-grade terrains, the borders of the Brasilia Block and the Transamazonian lineaments have been preferentially affected. The tectono-magmatic manifestations of the Wealdenian Reactivation, related to the opening of the Atlantic Ocean, occurred mostly among the uplifted zones (Alto Paranaiba Uplift) that developed partially until the rift stage (Mantiqueira Uplift). These processes clearly reveal the influence of the old structures of the state of Minas Gerais. The Mantiqueira Uplift presents a more accentuated seismic activity and thermal flow regime than the neighboring regions, so corresponding to the present less stable area of Minas Gerais. (DJM) [pt

Full Text Available RESUMO O artigo procura entender o governo Dilma Rousseff e o Golpe de 2016 levando em consideração o poder estrutural do capital financeiro e as contradições inerentes aos modelos de crescimento econômico e coalizão política observados desde o governo Lula. Argumenta-se que o projeto econômico do governo Rousseff procurava superar algumas destas contradições. O governo, contudo, não foi capaz de realizar nem as reformas institucionais nem as repactuações políticas necessárias para o sucesso de seu projeto, em contexto de desaceleração cíclica e aguçamento da concorrência internacional e dos conflitos sociais no Brasil. A política econômica é avaliada desde a austeridade de 2011 até a de 2015, passando pela chamada Nova Matriz Econômica e seu desmonte gradual em 2013. Analisa-se as origens da unificação da burguesia em torno a um programa neoliberal em 2016, assim como a relação entre a revolta das camadas médias e o ataque político-judicial resultante no Golpe de 2016.

The Bolivia-Brazil natural gas pipeline, which transports natural gas more than 3000 km from Bolivia to Brazil, cost US$2.1 billion to construct. Despite the substantial benefits for both Bolivia and Brazil and the involvement of reputable private partners, the perceived risks and complexities of this large project made financing it major challenge. neither of these countries has had a tradition of independent regulation or economic fuel pricing, and the pipeline was the first major gas infrastructure project involving the private sector in Brazil. The presentation explains the historical features of the project and how the project was used to open up Brazilian oil and gas sector to private investment and competition. (author)

U-Pb and origen of the Uruana quartz syenite and Itapuranga alkali granite in Goias, central Brazil: Late Braziliano alkali-rich magmatism in the Anapolis-Itaucu complex

International Nuclear Information System (INIS)

Pimentel, Marcio Martins; Dantas, Elton Luis; Fuck, Reinhardt Adolfo

2001-01-01

The Brasilia Belt is part of a Brasiliano/Pan African orogen developed between the Amazon and Sao Francisco cratons (for a review see Pimentel et al. 2000 and Dardenne 2000). The stabilization of the belt occurred after the last metamorphic event at ca. 620±20 Ma. Until recently, important late- to post-orogenic Neoproterozoic granitic magmatism was recognized mostly within the limits of the Goias Magmatic Arc, in the western part of the orogen. Recent studies by Pimentel et al. (1999) and Fischel et al (1999), as well as some unpublished U-Pb SHRIMP geochronological data, have also shown that Neoproterozoic granites represent an important component of the Anapolis- Itaucu Complex, a high grade terrain exposed in the central part of the Brasilia Belt, in between metasediments (Araxa Group) of the internal part of the belt. In the northern part of this granulitic complex, two alkali rich intrusions, the Uruana quartz syenite and the Itapuranga alkali suite (Lacerda Filho and Oliveira 1995) form large bodies elongated in the E-W direction. Their age and tectonic significance has been the matter of continuous debate. In this study we present new conventional and SHRIMP U-Pb results as well as whole-rock Sm-Nd data for samples of these intrusions (au)

On January 1, 1995, Brazil was integrated to the world-wide seismic system, through the Seismological Observatory of the University of Brasilia, dedicated to detect and identify underground nuclear explosions. This is an unprecedented global effort program to conduct a seismic test of rapid data collection, distribution and processing evolving the most advanced sensors, global communications and data processing technologies. By the end of February, 49 countries were incorporated and the present test represents a first training step towards the final definition of an International Monitoring System to monitoring a Comprehensive test Band Treaty. Besides accomplishing its main goal, the global monitoring program will be able to supply rapidly, through the International Data Center, important information to the seismological community.

Valberg, Anna Helene

2011-07-01

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

2000-01-01

Almost all the electric power in Brazil comes from large-scale hydroelectric plants: only about 3% comes from cogeneration. But, now that the barriers which discouraged cogeneration are being removed, there will be more and more investment in cogeneration and distributed generation. The circumstances which have brought about these changes are described. It is expected that cogeneration will be responsible for producing 10-15% of Brazil's electricity by 2010 and the demand for cogeneration will reach 11-17 GW. It is concluded that Brazil represents one of the world's most attractive market for cogeneration and distributed generation

The present study aimed to assess the safety of gluten-free bakery products for consumption by coeliac patients. Design/setting In the current exploratory cross-sectional quantitative study, a total of 130 samples were collected from twenty-five bakeries in Brasilia (Brazil). For the quantification of gluten, an ELISA was used. The threshold of 20 ppm gluten was considered as the safe upper limit for gluten-free food, as proposed in the Codex Alimentarius. The results revealed a total of 21·5 % of contamination among the bakery products sampled. Sixty-four per cent of the bakeries sold at least one contaminated product in our sample. These findings represent a risk for coeliac patients since the ingestion of gluten traces may be sufficient to adversely impact on their health.

Full Text Available O armazenamento de produtos agrícolas cumpre um papel importante no agronegócio. Observa-se uma tendência cada vez maior em se trabalhar com produtos a granel, em grandes volumes. Visando a uma concepção construtiva racional e econômica, o presente trabalho propõe um sistema misto em concreto armado e alvenaria estrutural aplicado a silos para armazenagem de produto agrícola a granel. No projeto proposto, o silo é composto de células em alvenaria estrutural, geminadas duas a duas na largura e com um número variável de células no comprimento, em função do volume desejado de armazenagem. Esse sistema simétrico favorece a racionalidade operacional, garantindo a continuidade entre os fluxos de recebimento e de expedição. O fundo da célula é em forma de tremonha dupla troncopiramidal, com saída central, construída em painéis treliçados pré-moldados. A sustentação das células e das tremonhas é feita através de vigas e de pilares de concreto armado. O isolamento térmico necessário para que a qualidade do produto armazenado seja garantida é estabelecido pela utilização de telhas trapezoidais de aço galvanizado, tanto na cobertura como nos fechamentos laterais.

Brazil is the tenth largest energy producer in the world, with an installed capacity of 105.986 MW. Brazil currently has an estimated 258.410 MW of hydroelectric power potential. Small hydropower (SHP) plants in Brazil are defined as plants capable of producing up to 30 MW of power, with a reservoir area smaller than 12 km 2 . It is estimated that SHP plants will provide 5 per cent of Brazil's electrical supply by 2030. SHP plants in Brazil typically use Kaplan and Pelton hydraulic turbines, as well as Michell-Banki cross-flow turbines. Hydrokinetic turbine prototypes are also being designed at the Federal University of Brazil. Researchers are currently developing a diffuser enhancement design. However, there are currently no designs available that use peripheric generators. Researchers are currently investigating the design of fish-friendly turbines as well as mobile dams. Development projects in the Amazon region were outlined. tabs., figs.

Brazil in the global energy world

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

The southeastern region of Brazil did not constitute a typical passive margin as one would expect from the premises of Plate Tectonics. After 25 m.y. that rifting (134-114 Ma) ceased an uplift of epeirogenic nature of the continental crust started in response to the drifting of the South American Plate over a thermal anomaly (Trindade hot spot). This Late Cretaceous (89-65 Ma) uplift was accompanied by intense alkaline (over non-extended crust) and basaltic (over thinned crust) magmatism. A marked absence of tectonism, however, also characterized this event. The resulting highlands extended over 300 000 km{sup 2} (Cretaceous Serra do Mar), and they were the main source area for coniacian-maastrichtian sediments of the Santos, Campos and Parana Basins. By the end of the rising (exactly at the K/T boundary) a widespread erosional surface had developed (Japi Surface) and leveled the top of the highlands at around 2 000 m (in relation to present-day sea level). This mega-plateau was adjacent to the subsiding Santos and Campos Basins and created an isostatically unstable situation. Gravitational collapse began around 7 m.y. after K/T, towards the depocenters of the basins. From Late Paleocene to Early Miocene (58-20 Ma) the continental crust broke and collapsed into a series of grabens, thus forming corridors (rifts) parallel to the current coastline. The ancient eastern edge of the Cretaceous Serra do Mar coincided with the current cretaceous hinge line of the Santos and Campos Basins. The topographic remnants of the mega-plateau nowadays form the highest parts of the Mantiqueira and Serra do Mar Ranges, modified by elastic rebound and tilting of the fault blocks. (author)

All about neosporosis in Brazil

Camila Koutsodontis Cerqueira-Cézar

2017-08-01

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

Full Text Available 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.

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.

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.

Challenges for malaria elimination in Brazil.

Science.gov (United States)

Ferreira, Marcelo U; Castro, Marcia C

2016-05-20

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

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

2017-12-01

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

Brazil's energy industry in a crisis

International Nuclear Information System (INIS)

Sangmeister, H.

1988-01-01

In volume 8/1986 of this periodical, Brazil's moving away from the program for the building and expansion of a national nuclear power industry had been reported on back of foreign currencies and urgently necessary saving measures of the public means influence not only the construction of nuclear power plants, they also decay instruments in other areas of energy industry. In the area of electric power, some nationalisations have already taken place and in petroleum supply, the need for imports is increasing again. Furthermore, there is reason to believe that some of the energy-political solutions which Brazil had chosen as answers to the petroleum price shocks of 1973/74 and 1979/80 are likely to lead to some considerable problems in the near future. In the middle of these crises in which Brazil's energy industry has been for some time now, there is nonetheless one spectacular event. Brazil's President, Mr. Jose Sarney, announced the command of the nuclear cycle by means of national technology. (orig.) [de

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

Energy Technology Data Exchange (ETDEWEB)

Husted Rich, N

1996-04-01

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

Brazil's mineral development: potential and problems

Energy Technology Data Exchange (ETDEWEB)

Lloyd, B; Wheeler, E

1977-03-01

Brazil's vast mineral wealth still lies in the ground largely unexploited. Lack of adequate communications and the past political instability of the country has greatly hampered mineral exploration, and risk capital for major schemes has only recently been forthcoming. In 1975, Brazil's oil imports alone cost US $3073 million, creating an unhealthy balance of payments deficit and causing the external national debt to reach US $22 billion by the end of that year--an increase of a further 25% in this debt took place during 1976. Substantial price rises in imported machinery followed that of oil, while the prices of Brazil's main exports, coffee, sugar and soya, have continued to fluctuate widely. As a result of the oil price rise Brazil has moved from a traditional trade balance to substantial deficit, although this has fallen from its 1974 peak of 4.6 billion, largely as a result of government policies. Brazil has untapped deposits of bauxite, tin, zinc, iron ore, nickel, as well as oil, and is firmly set on the path that will make her one of the world's major sources of raw materials by the year 2000. The government has made the exploitation of natural resources, particularly the previously neglected oil and gas sectors, one of the cornerstones of its economic strategy. Yet in 1975 the mineral sector produced less than 2% of Brazil's GNP, although it did contribute 11% of exports. Apart from iron oreand manganese, mineral production is small and the country is still a net importer of copper, zinc, nickel, tin, and lead. Without a substantial increase in exports the government's whole economic/social and political strategy will be at risk.

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.

Lindoso, José Angelo L; Lindoso, Ana Angélica B P

2009-01-01

Poverty is intrinsically related to the incidence of Neglected Tropical Diseases (NTDs). The main countries that have the lowest human development indices (HDI) and the highest burdens of NTDs are located in tropical and subtropical regions of the world. Among these countries is Brazil, which is ranked 70th in HDI. Nine out of the ten NTDs established by the World Health Organization (WHO) are present in Brazil. Leishmaniasis, tuberculosis, dengue fever and leprosy are present over almost the entire Brazilian territory. More than 90% of malaria cases occur in the Northern region of the country, and lymphatic filariasis and onchocerciasis occur in outbreaks in a particular region. The North and Northeast regions of Brazil have the lowest HDIs and the highest rates of NTDs. These diseases are considered neglected because there is not important investment in projects for the development of new drugs and vaccines and existing programs to control these diseases are not sufficient. Another problem related to NTDs is co-infection with HIV, which favors the occurrence of severe clinical manifestations and therapeutic failure. In this article, we describe the status of the main NTDs currently occurring in Brazil and relate them to the HDI and poverty.

Clínica Psicodinâmica do Trabalho: a prática em diversos contextos de trabalho

Full Text Available This study aims to present clinical practice under various work contexts, recently held from North to South of Brazil. The psychodynamic clinic of labour is characterized by the analysis of mental processes mobilized by the meeting between the subject and the impositions generated by the work organization five clinical practices are presented that are developed in laboratories of labor psychodynamics at the University of Brasilia (DF, Federal University of Amazonas and Federal University of Rio Grande do Sul, Brazil. These practices provide a systematic methodology in labour clinic resulting in unique practices depending on the sociocultural and institutional reality of each studied category. The reported experiences show the demand diversity and the importance of the clinic listening of work suffering. The reports show that the distance between the prescribed and the true rules which triggers the suffering is also the researchers' tasks, requiring mobilization and creation of suitable alternatives in each reality. It also indicates the need for future studies to articulate other fields that contribute to deepen the use of listening devices. It seems a powerful reference for psychoanalysis. This articulation contributes to suffering's analytical listening and supports a construction proposal of an Analytical Clinic of Labour.

2015-10-01

Group analytic practice in Brazil began quite early. Highly influenced by the Argentinean Pichon-Rivière, it enjoyed a major development from the 1950s to the early 1980s. Beginning in the 1970s, different factors undermined its development and eventually led to its steep decline. From the mid 1980s on, the number of people looking for either group analytic psychotherapy or group analytic training decreased considerably. Group analytic psychotherapy societies struggled to survive and most of them had to close their doors in the 1990s and the following decade. Psychiatric reform and the new public health system have stimulated a new demand for groups in Brazil. Developments in the public and not-for-profit sectors, combined with theoretical and practical research in universities, present promising new perspectives for group analytic psychotherapy in Brazil nowadays.

Allelopathic research in Brazil

Full Text Available In this article, we review allelopathy studies conducted in Brazil or involving plant species that occur in the country. Conceptions and misconceptions associated with allelopathy, as well as some international criteria to be applied in allelopathic research, are presented and discussed. We observed a sharp increase in the number of papers on this subject conducted in Brazil between 1991 and 2010. However, most studies are conducted under laboratory conditions, lack a clear hypothesis or a solid justification, and typically make use of target species that do not co-exist with the donor species under natural conditions. We also found that most studies do not take the additional steps in order to purify and identify the bioactive molecules. We recommend that further studies be conducted in order to explore the potential of plant biodiversity in Brazil. Such studies could lead to the development of new molecular structures (allelochemicals that could be used in the control of pests and weeds, thereby reducing the use of the harmful synthetic herbicides that are currently being widely employed.

Brazil: anchoring the region

Costamilan, L.C.L.

1997-01-01

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

Health and innovation: economic dynamics and Welfare State in Brazil.

Gadelha, Carlos Augusto Grabois; Braga, Patrícia Seixas da Costa

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

Occupational health and safety in Brazil.

Brazil is the world's fifth largest and sixth most populous nation. Its economy is varied, with strong manufacturing, agriculture, mining, and service sectors. Therefore, a wide variety of workplace hazards confronts its work force. This paper describes Brazil's occupational safety and health regulatory scheme, workers' compensation system, plant-level practices, training, and data collection. We reviewed and analyzed Brazilian regulatory legislation and government and non-governmental organization (NGO) activity in occupational safety and health, as well as the structure and function of the workers' compensation system. We also reviewed available data on injuries and diseases from major sources, including the now-defunct Instituto Nacional do Previdencia Social (INPS) and the workers' compensation scheme, Seguro de Acidente de Trabalho (SAT). The incidence of workplace injuries has decreased in recent years and is now reported to be about 5 per 100 workers per year. The case fatality rate has been constant at about 5 fatalities per 1000 injuries. Less than 6% of reported injuries are classified as "diseases." Brazil's rates are comparable to those of Mexico and Zimbabwe, and two to four times higher than in most industrialized countries. Brazil has a high incidence of occupational injuries and diseases; these injuries and diseases are underreported; there is a large informal sector at special risk; and Brazil illustrates the disparity that exists in many countries between legislation on the books and legislation that is actually implemented.

The victory against Greenpeace-Brazil

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

The city of Annapolis is located 48 kilometers from the capital, Goiania, in Goias Center Mesorregion, which forms part of the Annapolis-Brasilia-Goiania axis, with an economy focused on manufacturing industry, pharmaceuticals, ceramics, wholesale and automobile industry, having a population of 335, 960 inhabitants (IBGE, 2009). The objective of this work is the physical and mineralogical characterization of three samples of clay of that region. The clays were characterized by granulometry determining distribution, Atterberg limits, chemical composition, X-ray diffraction and differential thermal analysis and thermogravimetry. Samples (cps) were obtained by extrusion and fired at 750 deg, 950 deg and 1050 deg C. After the burning process it was determined the water absorption, bending rupture's modulus. The analyzed results show the physical and mineralogical composition of raw materials and concluded that this characterization allows to estimate that the three samples are appropriate or not for the production of ceramic products.(author)

Bolivia's gas heads for Brazil as Argentina waits - and watches

International Nuclear Information System (INIS)

Knight, P.

1998-01-01

The first 1,800 km stretch of a 3,400 km natural gas pipeline from Bolivia to Brazil will start operating in December. First planned 50 years ago, the pipeline has long been expected to result in an immediate surge of gas use in Brazil. However, impending deep recession in Brazil makes this prospect less likely despite the power shortages which indicate the need for considerable gas imports. Initially, most Bolivian gas will flow through Brazil to Argentina. But gas production is expanding rapidly in Argentina and the supply contract with Bolivia ends in 1999. Plans are well advanced to build two gas lines into the south of the Brazil from Argentina. Ultimately, it is anticipated that Argentina, which has abundant reserves and a virtually saturated domestic market, will become the principal source of natural gas for Brazil. (UK)

With its area of 8.5 million square kilometers (3.3 million square miles) Brazil is the world's fifth largest nation, occupying almost one half of the continent of South America. Its vastness and its wide variety of geological terrain suggest that parts of Brazil may be favorable for many kinds of uranium deposits. The nation's favorability for uranium is indicated by the high correspondence between discoveries and the amount of exploration done to date. For the first time, the uranium and thorium resources of Brazil and their geologic setting are described here in a single volume. 270 refs

Presence of p-synephrine in teas commercialized in Porto Alegre (RS/Brazil

Full Text Available Citrus aurantium (bitter orange is characterized by the presence of p-synephrine, an amine structurally and pharmacologically related to ephedrine. Besides the same adverse effects as ephedrine, nowadays it is believed that altered levels of p-synephrine can be associated to the occurrence of migraine and cluster headaches. Leaves and fruits of this species are highly commercialized in form of teas and herbal preparations, but without taking into account the risks associated with its use. This work describes a survey of teas and herbal preparations containing C. aurantium, commercialized in Porto Alegre (RS/Brazil, in order to verify the presence of p-synephrine. Comparing with the mean amount available in the supermarkets, around 20% of the teas and 10% of the herbal preparations declared the presence of C. aurantium in their labels. In a sampling of 15 teas and 2 herbal preparations selected for the analysis, the presence of p-synephrine was characterized in all samples, with levels between 0.0040 to 0.2308%, leading to a caution that even being natural products, they are not free of adverse effects.Citrus aurantium (laranjeira-azeda é caracterizada pela presença de p-sinefrina, amina estrutural e farmacologicamente similar à efedrina. Além de poder causar efeitos adversos similares aos da efedrina, atualmente acredita-se que níveis endógenos alterados de p-sinefrina possam estar associados à causa da enxaqueca. Folhas e frutos desta espécie são largamente comercializados na forma de chá e em preparados de erva-mate, sem que sejam considerados os riscos associados ao seu uso. Neste sentido, este trabalho descreve uma pesquisa em chás e preparados de erva-mate comercializados em Porto Alegre, para verificar a presença de C. aurantium e p-sinefrina. Comparando com a quantidade média disponível nas prateleiras dos supermercados, cerca de 20% dos chás e 10% dos preparados de erva-mate declaravam nos rótulos conter C. aurantium. De

The exposure to cosmic radiation from air traveling is significantly higher than that at ground level, varying according to the route due to the effect of latitude and flight time, to the flight altitude, due to the type of airplane and to the year, due to the effect of solar cycle on the galactic cosmic rays flux. The computer code CARI-6, developed by the U.S. Federal Aviation Administration, is aimed to calculate the effective dose of galactic cosmic radiation received by an individual in an airplane, flying the shortest route between two airports in the world. The objective of this work is to estimate the contribution of the exposure to cosmic radiation on domestic commercial flights for the Brazilian customers. The work shall serve as a baseline for future comparisons of the growth of civil aviation in the country. It shall also open perspectives for discussions on the concept of risk and its public acceptance, relevant to the establishment of radiological protection guidelines. Average effective doses for individual flights ranged from 0.2 to 8.8 μSv. This is a very small contribution to average overall exposure to natural background radiation (2.4 mSv/y). Doses for the most frequent flight routes in the country have been assessed. These include flights to and from Rio de Janeiro, Sao Paulo and Brasilia. Doses for frequent flyers and collective doses are discussed in perspective of other exposure sources. (author)

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.

The main objective of this study is to analyze the bicycle rental system in the Federal District {sup B}ike Brasilia{sup .} It aims to identify guidelines that supported the application process and consensus, disagreements and guidelines established by the Institute for Policies and Development in Transportation - ITDP and relate those listed by Zhang regarding rented bikes systems. This is an exploratory study based on the strategy of document analysis and its secondary sources: institutional documents, basic design, procurement and other official documents made exclusively for this study. To support the discussion, a systematic literature review of the rules describing specially: sustainability, transport, urban mobility, bicycle rental and environment. The results reveal that while some of the parameters and indicators of efficiency are met on time, the bicycle sharing system of the city of Brasilia, has weaknesses that can lead to inefficiency and impracticality of maintaining and expanding such services. On the other hand, Bike Brasilia partially fulfills the principles enumerated by Zhang and lacks improvement in the steps for the successful operation of the system. (Author)

Rousseau, I.

2009-01-01

Thanks to its efficient petroleum framework, Brazil has just found some very large deep off-shore fields (pre-halite layers), which, if confirmed, will allow the country to become a major international oil producer. There will be significant repercussions on Brazil. On the one hand, the prospect of high economic rents encourages it to assign its hydrocarbon industry a more social and national calling; on the other hand, this huge potential offers Brazil a new geopolitical dimension. This article examines both these avenues. (author)

Placing Brazil's heavy acid oils on international markets

International Nuclear Information System (INIS)

Szklo, Alexandre Salem; Machado, Giovani; Schaeffer, Roberto; Felipe Simoes, Andre; Barboza Mariano, Jacqueline

2006-01-01

This paper identifies the international market niches of Brazil's heavy acid oils. It analyzes the perspectives for making wider use of heavy acid oils, assessing their importance for certain oil-producing regions such as Brazil, Venezuela, West Africa, the North Sea and China. Within this context, the oil produced in the Marlim Field offshore Brazil is of specific interest, spurred by the development of its commercial brand name for placement on international markets and backed by ample production volumes. This analysis indicates keener international competition among acid oils produced in Brazil, the North Sea and the West Coast of Africa, through to 2010. However, over the long term, refinery conversion capacity is the key factor for channeling larger volumes of heavy acid oils to the international market. In this case, the future of acid oil producers will depend on investments in refineries close to oil product consumption centers. For Brazil, this means investments in modifying its refineries and setting up partnerships in the downstream segment for consumer centers absorbing all products of high added value, such as the USA and even Southeast Asia and Western Europe

Environmental sustainability of biodiesel in Brazil

Biodiesel production in Brazil has grown from 736 m 3 in 2007 to 2.7 Mm 3 in 2012. It is an emergent bioenergy for which it is important to guarantee environmental sustainability. The objective of this article is to characterise the biodiesel production chain in Brazil, to identify potential environmental impacts and to analyse key drivers and barriers for biodiesel environmental sustainability. This article explores these aspects and focusses on the increasing demand for the main feedstocks for biodiesel production in Brazil: soybean oil and beef tallow. The impacts of land use and land-use change on greenhouse gas emissions, biodiversity and water, as well as the energy balance, were found to be critical for the environmental sustainability assessment and development of biodiesel chains. Increasing agriculture yields, diversifying feedstocks and adopting ethyl transesterification can contribute to minimise environmental impacts. It was also found that environmental impacts could be mitigated by appropriate policies aiming at an integrated optimisation of food and bioenergy production and through agro-economic–ecological zoning, allowing adequate use of land for each purpose. Despite the limitation and weakness of some sustainability tools and initiatives, certification and zoning can play an important role in the sustainability of the emerging biodiesel production in Brazil

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.

US/Brazil joint pilot project objectives

1997-12-01

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.

One of the main questions in electricity market deregulation is the aptitude of private capital for investments in power generation. This is especially important in Brazil, whose load has a strong growth trend ({approx}6% per year). Thermopower is an attractive alternative for expanding generation, as it is complementary in many aspects to hydropower, which supplies most Brazil's power at a very low price most of the time, but makes the system vulnerable to seasonal water variations. This paper studies the competitiveness of thermopower generation in Brazil under current regulations; assesses under the real options theory approach the conditions for investments in thermopower generation, and finally presents and discusses a hydropower generation schedule model.

Sm-Nd and U-Pb isotopic data on rocks of the Canastra and Vazante groups suggest derivation from predominantly Meso to Paleoproterozoic sources for these tectonic units of the Brasilia Range. T_D_M model ages between 1.76 and 2.85 Ga are consistent with continuous supply of sources with long crustal residence time and / or mix between old and younger sources.

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.

Full Text Available 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.

Mesozoic dinosaurs from Brazil and their biogeographic implications.

Science.gov (United States)

Bittencourt, Jonathas S; Langer, Max C

2011-03-01

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.

Angiostrongylus cantonensis and Rat Lungworm Disease in Brazil

de Oliveira Simões, Raquel; Fernandez, Monica Ammon; Júnior, Arnaldo Maldonado

2013-01-01

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. PMID:23901376

Economic losses due to bovine brucellosis in Brazil

Directory of Open Access Journals (Sweden)

Renato L. Santos

2013-06-01

Full Text Available Brucellosis is an important zoonosis of worldwide distribution. Reliable epidemiologic brucellosis data covering approximately 90% of the cattle population in Brazil have been recently published. Therefore, considering the scarcity of information regarding the economic impact of bovine brucellosis in Brazil, the goal of this study was to estimate economic impact of brucellosis on the Brazilian cattle industry. Several parameters including abortion and perinatal mortality rates, temporary infertility, replacement costs, mortality, veterinary costs, milk and meat losses were considered in the model. Bovine brucellosis in Brazil results in an estimated loss of R$ 420,12 or R$ 226,47 for each individual dairy or beef infected female above 24 months of age, respectively. The total estimated losses in Brazil attributed to bovine brucellosis were estimated to be approximately R$ 892 million (equivalent to about 448 million American dollars. Every 1% increase or decrease in prevalence is expected to increase or decrease the economic burden of brucellosis in approximately 155 million Reais.

Historical amphibian declines and extinctions in Brazil linked to chytridiomycosis.

Carvalho, Tamilie; Becker, C Guilherme; Toledo, Luís Felipe

2017-02-08

The recent increase in emerging fungal diseases is causing unprecedented threats to biodiversity. The origin of spread of the frog-killing fungus Batrachochytrium dendrobatidis ( Bd ) is a matter of continued debate. To date, the historical amphibian declines in Brazil could not be attributed to chytridiomycosis; the high diversity of hosts coupled with the presence of several Bd lineages predating the reported declines raised the hypothesis that a hypervirulent Bd genotype spread from Brazil to other continents causing the recent global amphibian crisis. We tested for a spatio-temporal overlap between Bd and areas of historical amphibian population declines and extinctions in Brazil. A spatio-temporal convergence between Bd and declines would support the hypothesis that Brazilian amphibians were not adapted to Bd prior to the reported declines, thus weakening the hypothesis that Brazil was the global origin of Bd emergence. Alternatively, a lack of spatio-temporal association between Bd and frog declines would indicate an evolution of host resistance in Brazilian frogs predating Bd 's global emergence , further supporting Brazil as the potential origin of the Bd panzootic. Here, we Bd -screened over 30 000 museum-preserved tadpoles collected in Brazil between 1930 and 2015 and overlaid spatio-temporal Bd data with areas of historical amphibian declines. We detected an increase in the proportion of Bd -infected tadpoles during the peak of amphibian declines (1979-1987). We also found that clusters of Bd -positive samples spatio-temporally overlapped with most records of amphibian declines in Brazil's Atlantic Forest. Our findings indicate that Brazil is post epizootic for chytridiomycosis and provide another piece to the puzzle to explain the origin of Bd globally. © 2017 The Author(s).

Schistosomiasis control in Brazil

Directory of Open Access Journals (Sweden)

Katz Naftale

1998-01-01

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

Transmission of Zika virus (ZIKV) in the Americas was first confirmed in May 2015 in northeast Brazil. Brazil has had the highest number of reported ZIKV cases worldwide (more than 200,000 by 24 December 2016) and the most cases associated with microcephaly and other birth defects (2,366 confirmed by 31 December 2016). Since the initial detection of ZIKV in Brazil, more than 45 countries in the Americas have reported local ZIKV transmission, with 24 of these reporting severe ZIKV-associated disease. However, the origin and epidemic history of ZIKV in Brazil and the Americas remain poorly understood, despite the value of this information for interpreting observed trends in reported microcephaly. Here we address this issue by generating 54 complete or partial ZIKV genomes, mostly from Brazil, and reporting data generated by a mobile genomics laboratory that travelled across northeast Brazil in 2016. One sequence represents the earliest confirmed ZIKV infection in Brazil. Analyses of viral genomes with ecological and epidemiological data yield an estimate that ZIKV was present in northeast Brazil by February 2014 and is likely to have disseminated from there, nationally and internationally, before the first detection of ZIKV in the Americas. Estimated dates for the international spread of ZIKV from Brazil indicate the duration of pre-detection cryptic transmission in recipient regions. The role of northeast Brazil in the establishment of ZIKV in the Americas is further supported by geographic analysis of ZIKV transmission potential and by estimates of the basic reproduction number of the virus.

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

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

2002-09-01

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.

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.

[Fertility transition in Brazil. Causes and consequences].

Science.gov (United States)

Carvalho, J A; Wong, L R

1992-12-01

This work examines the determinants and most important consequences of the Brazilian fertility decline. Brazil's total fertility rate declined from 6.2 in 1940 to around 3.5 in 1985. the decline began in the 1960s and amounted to 45% in about 20 years. The most rapid drop began in the late 1970s, with much of it concentrated in 2 specific periods: 1970-75 and 1980-85. The early period coincided with Brazil's so-called "Economic Miracle", a period of rapid growth accompanied however by deteriorating living conditions for the poorest population sectors. The second period coincided with the international economic crisis of the early 1980s, which was felt more strongly in Brazil than elsewhere in Latin America because of Brazil's greater degree of industrialization and closer integration into the world economy. Most of the fertility decline has been accomplished by use of just two contraceptive methods, oral contraceptives and sterilization, which together account for around 85% of contraceptive usage throughout Brazil. The third most common method, rhythm, accounts for just 6%. No reliable data on abortion are available, but it appears to be a common practice equally accessible to all socioeconomic strata despite greater associated health risks for poorer women. Brazil's fertility transition appears to have been a response to the process of proletarianization and urbanization underway in the country as well as to particular circumstances in the country. The most evident and immediate consequence of the continuous fertility decline over more than 20 years is the change in the age structure of the population. The proportions of children under 5 will decline from 14.4% in 1980 to 9.2% in 2010. The proportion aged 5-14 will decline from 24.5% to 17.4%, while the proportion aged 65 and over will increase from 4.0% to 5.6%. Brazil's recent demographic changes are scarcely reflected in development plans and political and social projects. There is almost no mention of the new

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.

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

Science.gov (United States)

Biasetto, Bruno Henz

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

Tax regulating carbon market in Brazil: barriers and perspectives

International Nuclear Information System (INIS)

Marques, Fernando; Magalhaes, Gerusa; Parente, Virginia

2010-01-01

The world is moving towards a low carbon economy to fight global warming caused by increases in anthropogenic emissions of greenhouse gases (GHGs). The carbon market beckons as a promising opportunity for Brazil through Clean Development Mechanism (CDM) projects, which result in Certified Emission Reductions (CERs). Although Brazil is responsible for about 8% of all CDM projects in the world, there is still no specific tax regulation for CERs, thus hindering the development of carbon market in Brazil. It is essential that Brazil have a consistent internal framework which guarantees to potential investors a minimum security on the legal and fiscal operations of CERs. There are government institutions, considering the current law and that, given the number of bills being processed in Congress, are not definitive. Such bills have different understandings for the legal classification of CERs and the related tax treatment. This article supports an urgent need for a regulatory tax system for CERs, proposing a tax exemption on transactions involving CERs in order to encourage the effective development of carbon markets in Brazil in the context of the currently international legal system in which Kyoto Protocol is based.

Kassenova, Togzhan

2017-11-01

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.

The climate change/energy efficiencies market in Brazil

International Nuclear Information System (INIS)

2000-03-01

In December 1997, one hundred and sixty countries negotiated the Kyoto Protocol, where a commitment was made by industrialized countries to reduce their greenhouse gas (GHG) emissions by 5.2 per cent below their 1990 level. This objective was to be achieved by 2008 to 2012. The Clean Development Mechanism (CDM) was promoted by Brazil in Kyoto. The CDM defines the mechanism by which investment, technologies and practices from developed countries are implemented in developing country projects. It is then possible to credit the emissions avoided by these projects against the supplier's own commitment to reducing GHG. An essential element of good business practice for the private sector and programs sponsored by the government in Brazil is sound environmental management. The Brazilian Federal Government, research institutes and few leading private companies are concerned with the climate change market. Climate change and environmental efficiency projects in Brazil are frequently funded by international financial institutions (IFIs), namely the World Bank, the Inter-American Development Bank (IDB), and the Canadian International Development Agency (CIDA). International partners who can help in obtaining IFIs funds are sought after by Brazilian companies. Before entering the Brazilian market, Canadian entrepreneurs should examine all aspects of exporting environmental equipment. Some investment in Brazil might be required to achieve long term penetration of the market. Since national companies are offered preferential treatment for obtaining government contracts, a local partner is almost indispensable. The cost of doing business in Brazil might even be increased when considering the import taxes, such as federal excise taxes, state value-added taxes, and the merchant marine tax. Brazil can represent a springboard to the South American markets due to its membership in trade groups like the Mercosul and the Latin American Integration Association (ALADI). 14 refs

Realism under Hegemony: Theorizing the Rise of Brazil

Directory of Open Access Journals (Sweden)

Kurt Weyland

2016-01-01

Full Text Available What light can international relations theory shed on how developing countries such as Brazil have achieved regional leadership and international influence? This comprehensive examination of Brazilian foreign policy over the last few decades argues that Realism provides a better account of Brazil’s strategy than Liberalism and Constructivism. Despite changes of government and regime, Brasília has persistently pursued relative political gain, especially international influence. However, because this rising country has faced an established hegemon in the form of the United States, it has not been able to employ conventionally Realist instruments and tactics. Its subordinate position in the current power constellation has forced Brazil to forego political or military confrontation and instead use economic cooperation, both with the hegemon and its weaker neighbors. Through this collaboration, Brazil hopes to derive disproportionate benefits that will enhance its relative power. By elucidating these complex calculations, the present essay explains the Realist strategy that ambitious nations such as Brazil have pursued and helps design a version of Realism that captures recent power dynamics in the international system.

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

2016-01-01

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.

2013-12-01

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.

Foram calculados os parâmetros fitossociológicos das espécies e das famílias botânicas para toda a área amostral e para cada um dos três setores da floresta. Foram obtidas medidas de dissimilaridade florística e estrutural entre os três setores amostrais e medidas de dissimilaridade florística entre a floresta do presente estudo e cinco outras florestas riparias do Distrito Federal e dos estados de São Paulo e Mato Grosso. As seis florestas apresentaram entre si índices muito altos de dissimilaridade florística, embora algumas delas apresentassem espécies em comum entre as mais abundantes. Os três setores amostrais mostraram igualmente uma considerável dessemelhança florística e estrutural entre si. O clima, os solos e a geomcrfologia das bacias hidrográficas são evocados como responsáveis pelas diferenças interregionais entre as florestas riparias. Já as dessemelhanças intrarregionais podem ser atribuídas à fertilidade dos solos e, sobretudo, ao regime de água nos solos e nos próprios rios, os quais, por sua vez, variam com a topografia local. Os padrões de distribuição espacial marcadamente diferentes que podem ser observados para várias espécies de árvores podem ser atribuídos à elevada heterogeneidade ambiental, peculiar às florestas de galeria.The gallery forest which occurs along one of the branches of the Córrego da Paciência, southern Mato Grosso, Brazil (15º 21'S, 55º 49'W, was surveyed by 67 plots of 30m² each (0.201 ha.

Miracle drug: Brazil approves never-tested cancer medicine.

Kuchenbecker, Ricardo S; Mota, Daniel M

2017-07-01

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.

Oil refining expansion criteria for Brazil

Tavares, M.E.E.; Szklo, A.S.; Machado, G.V.; Schaeffer, R.; Mariano, J.B.; Sala, J.F.

2006-01-01

This paper assesses different strategies for the expansion of Brazil's oil refining segment, using criteria that range from energy security (reducing imports and vulnerability for key products) through to maximizing the profitability of this sector (boosting the output of higher value oil products) and adding value to Brazil's oil production (reducing exports of heavy acid oil). The development prospects are analyzed for conventional fuel production technology routes, sketching out three possible refining schemes for Brazilian oil and a GTL plant for producing gasoil from natural gas. Market scenario simulations indicate that investments will be required in Brazil's oil refining segment over and above those allocated to planned modifications in its current facilities, reducing the nation's vulnerability in terms of gasoil and petrochemical naphtha imports. Although not economically attractive, oil refining is a key activity that is crucial to oil company strategies. The decision to invest in this segment depends on local infrastructure conditions, environmental constraints and fuel specifications, in addition to oil company strategies, steady growth in demand and the definition of a government policy that eases institutional risks.

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.

Consumption of fast food and ready-to-eat meals has been positively associated with obesity. In the UK, ready-made meals are more often consumed than in Brazil, a country in which nutrition transition is relatively low. This study aimed to compare the nutritional quality of the main meal consumed by adults in Brazil and UK. Food record data was obtained from representative samples from UK and Brazil databases. The Main Meal Quality Index (MMQI) was applied to estimate the quality of the main meal consumed in Brazil and UK. Differences in food groups consumed in the main meal in Brazil and UK were observed using classification decision tree. Meals with higher average energy content were lunch for Brazil, and dinner for the UK. On average, the Brazilian main meal had better nutritional quality (4.42 times higher), independently of sex, age, family income, nutritional status and energy consumed, with higher scores of fiber, carbohydrate, total fat, saturated fat and energy density. However, UK's main meal included more fruits and vegetables. Food preparations combined with rice and beans were classified as Brazilian main meal, while combinations with fast food items, as fried potatoes, sandwiches and sugary beverages, were classified as UK main meals. In Brazil, the main meal quality was lower among women and obese individuals, presenting significant positive association with age, and negative association with energy intake and family income; while in UK, only age was positively associated with MMQI. Although main meals in Brazil had higher nutritional quality compared to the UK, main meals consumed in both countries need nutritional improvement. Copyright © 2017 Elsevier Ltd.

West Germany and Brazil, by seeking to establish their independence in the transfer of nuclear technology to a developing country, have raised international anxieties over how to finance and manage nuclear trade in a way that will secure peace. The deal, which commits the two countries to a program of uranium exploration and mining, enrichment, fuel fabrication and reprocessing, and power plant construction, means food supplies, jobs, and contracts for Germany and economic development for Brazil. Of concern to the rest of the world are the opportunities for diverting nuclear materials to weapons. Both countries have agreed to comply with the International Atomic Energy Agency's safeguards agreement, but Brazil is not bound by it. Brazil's development is making her the dominant power in South America and altering her relationship with the United States. A review of the West German-Brazilian agreement focuses on the historical competition for export markets and the lessening of U.S. control over the enriched uranium market

Privatization of Brazil's petroleum sector on track despite scandal

1992-01-01

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

Full Text Available This study presents an analysis of the reality of credit unions in Brazil, in view of the singular importance of credit unions for the whole society as an alternative to private resources in favor of members of the community where they are located. It confirms that, in Brazil, the mutual credit unions, besides being presented as one of the viable options within the financial system, are also seen as an alternative by which some sectors of society promote the humanization of the financial system by offering credit and return on capital with fairer interest rates.

The International Heliophysical Year is a program of international scientific colaboration planned to be held in the period from 2007-2009. Many brazilian institutions have shown interest in participating in the IHY activities. All of them provided information about their instrumental facilities and contact person. A list of institutions and their information is shown in the Latin-American IHY webpage (http://www.alage.org/IHYLA/ihyla.html), hosted by the Latin American Association on Space Geophysics - ALAGE. IHY Brazilian activities are being conducted in close colaboration with Latin-American Institutions. Five Coordinated Investigation programs (CIPs) have been proposed by scientists from brazilian institutions. Recentely, in February 2008, there has been the Latin American IHY School in Sao Paulo (Brazil), with the participation of 80 students from Brazil, Argentina, Peru, Mexico and Cuba. In this work, a report on the brazilian activities will be presented.

The privatization of medical education in Brazil: trends and challenges.

Scheffer, Mário C; Dal Poz, Mario R

2015-12-17

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

Origin and evolution of dengue virus type 3 in Brazil.

The incidence of dengue fever and dengue hemorrhagic fever in Brazil experienced a significant increase since the emergence of dengue virus type-3 (DENV-3) at the early 2000s. Despite the major public health concerns, there have been very few studies of the molecular epidemiology and time-scale of this DENV lineage in Brazil. In this study, we investigated the origin and dispersion dynamics of DENV-3 genotype III in Brazil by examining a large number (n=107) of E gene sequences sampled between 2001 and 2009 from diverse Brazilian regions. These Brazilian sequences were combined with 457 DENV-3 genotype III E gene sequences from 29 countries around the world. Our phylogenetic analysis reveals that there have been at least four introductions of the DENV-3 genotype III in Brazil, as signified by the presence of four phylogenetically distinct lineages. Three lineages (BR-I, BR-II, and BR-III) were probably imported from the Lesser Antilles (Caribbean), while the fourth one (BR-IV) was probably introduced from Colombia or Venezuela. While lineages BR-I and BR-II succeeded in getting established and disseminated in Brazil and other countries from the Southern Cone, lineages BR-III and BR-IV were only detected in one single individual each from the North region. The phylogeographic analysis indicates that DENV-3 lineages BR-I and BR-II were most likely introduced into Brazil through the Southeast and North regions around 1999 (95% HPD: 1998-2000) and 2001 (95% HPD: 2000-2002), respectively. These findings show that importation of DENV-3 lineages from the Caribbean islands into Brazil seems to be relatively frequent. Our study further suggests that the North and Southeast Brazilian regions were the most important hubs of introduction and spread of DENV-3 lineages and deserve an intense epidemiological surveillance.

To identify and synthesize the national and international literature on forensic nursing in Brazil. Forensic nursing is a new specialty to the nursing practice in Brazil, being recognized by the Federal Nursing Council of Brazil in 2011. In 2016, the first forensic nursing specialization programme was authorized in the country. The implementation of forensic nursing specialty in Brazil marks new possibilities for the nursing practice, making it possible for nurses to develop additional skills to intervene in various situations under the Brazilian Unified Healthcare System. A systematic search of the literature was conducted using the keyword 'Forensic nursing' in combination with 'Brazil'. LILACS, MEDLINE, EMBASE, Scopus and Web of Science databases were searched. Studies were also retrieved from the grey literature. Once literature had been identified, a thematic analysis was undertaken in order to extract themes, which were: establishment of the forensic nursing specialty and its contributions to Brazil and its practical implications. Eight manuscripts and 20 studies from the grey literature were included in the final review. Most studies (54%) were literature reviews that indicated forensic nursing as an emerging specialty in Brazil, addressing educational, instructional, communicative or contextual aspects of the specialty in the country. In the nursing profession in Brazil, few studies exist on forensic nursing and those are limited to short communications. Although most studies address the definition of forensic nursing, others present its implications in various situations such as intimate partner violence, domestic violence, sexual abuse and elder mistreatment. Despite the study limitations, it provides evidence that forensic nursing has been silently implemented in the country with the need for more evidence-based studies to support its constitution as a specialty in Brazil. © 2016 International Council of Nurses.

Zika and Reproductive Rights in Brazil: Challenge to the Right to Health.

Science.gov (United States)

Valente, Pablo K

2017-09-01

The Zika virus epidemic rapidly spread across Brazil and Latin America, gaining international attention because of the causal relationship between Zika and birth defects. The high number of cases in Brazil has been attributed to a failure of the state to contain the epidemic and protect the affected people, especially women. Therefore, the public health crisis created by Zika exposed a stark conflict between Brazil's constitutional right to health and the long-standing violation of reproductive rights in the country. Although health is considered to be a right of all in Brazil, women struggle with barriers to reproductive services and lack of access to safe and legal abortions. In response to the epidemic, women's rights advocates have filed a lawsuit with Brazil's supreme court that requires the decriminalization of abortion upon the diagnosis of Zika virus. However, the selective decriminalization of abortion may lead to negative social consequences and further stigmatization of people with disabilities. A solution to the reproductive health crisis in Brazil must reconcile women's right to choose and the rights of people with disabilities.

Em 2009, The Palgrave Handbook of Childhood Studies foi publicado, indicando o reconhecimento da área dos estudos da infância. Sabe-se que as crianças foram principalmente investigadas pela psicologia ou pela pedagogia e que as ciências sociais pouco produziram sobre elas, priorizando estudos sobre a família ou sobre a escola. Há pouco mais de vinte anos, entretanto, começaram a tornar-se o foco dos estudos sociais da infância, que a tomaram como um fenômeno social.

Globalization is often thought of as being associated with increasing environmental problems. In particular this is true in connection with dramatic financial crises. Experience from the financial crisis in Brazil in 1998 to 1999, however, shows a more varied picture in which parts of the environmental policy were indeed improved. The article also discusses how representative the example of Brazil might be for generalization and points out that the reaction of Brazil on the financial crisis was mitigated by that country being a strong democracy with robust institutions

Dynamics of Cattle Production in Brazil.

Directory of Open Access Journals (Sweden)

Concepta McManus

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

Noise in large cities in Brazil

Gerges, Samir N. Y.

2004-05-01

Large cities' noise is considered by the World Health Organization to be the third most hazardous pollution, preceded by air and water pollution. In urban centers, in general, and especially in developing countries such as Brazil, large populations are affected by excessive noise due mainly to traffic flow. The Brazilian Federal Government specifies noise limits, but each state can enforce its own set of noise limits, providing they are lower. The rapid economic growth, together with large migration of northern Brazilians to the developing southern urban areas in search of more lucrative jobs in construction and industrial sectors, resulted in a fast increase in activities such as vehicle and bus traffic, home construction, and development of all necessary infrastructures to support this growth. Urban noise in Brazil has been receiving the attention of national authorities only since 1990, when the Federal Government approved the first ``Program of Community Silence,'' based on ISO R 1996-1971. This paper highlights the noise situation in the five largest and most populated cities in Brazil: Sao Paulo, Rio de Janeiro, Belo Horizonte, Porto Alegre and Curitiba [Zannin et al., Appl. Acoust. 63, 351-358 (2002)].

Participation of the author in the Interdepartmental Committee on Nutrition for National Defense sponsored nutrition surveys of Burma and northeast Brazil is described. These surveys not only collected important data on nutritional status but also guided the subsequent research interests of the author. The Brazil survey results contributed to the creation of legislation that mandated the addition of water-dispersible vitamin A to skimmed-milk powder products. This additive has greatly diminished the likelihood of vitamin A deficiency syndrome occurring in children after famine relief efforts.

Fast reactor research activities in Brazil

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

Bilateral cooperation between Germany and Brazil on fuel irradiation

International Nuclear Information System (INIS)

Dias, J.W.

1977-01-01

Within the framework of the Government Agreement on Scientific and Technical Cooperation between the Federal Republic of Germany and Brazil, the Brazilian National Atomic Commission and the Juelich Nuclear Research Center (KFA) signed on 23rd April, 1971 an Agreement on Cooperation in the field of Nuclear Research and Reactor Technology. Projects have been elaborated in fields of mutual interest to share activities between the partner institutes in both countries. A typical project is the fuel irradiation programme jointly prepared by NUCLEBRAS and KFA-Juelich. Brazil is planning to use elements of its own production in nuclear power plants to be erected within the German-Brazilian Industrial Agreement. As no material test reactor is available in Brazil it is expedient to irradiate samples of Brazilian production in Germany. Brazilian collaborators will participate in the preparation, execution and post-irradiation examination. In this way an optimum transfer of all information and results is assured. In the first phase, sample rods manufactured in Brazil are irradiated in the FRJ-2 test reactor in Juelich. These rods are assembled under clean conditions in the NUCLEBRAS research centres. The first Brazilian test rods showed excellent in-pile behaviour even under very high fuel rod capacity. In the second phase, fuel rods of original length manufactured and assembled in Brazil will be irradiated in German power plants, and, at the same time, additional irradiations of small samples will be carried out in test reactors. In the third phase, rod clusters and complete fuel elements will be manufactured in Brazil and irradiated in German power plants until target burn-up. All the necessary prerequisites have been fulfilled to meet the above requirements, i.e. mutual interest, good infrastructure maintained by both partners, qualified personnel and last but not least unbureaucratic and effective help by the coordinating offices of NUCLEBRAS and KFA

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

2016-01-01

In the region of the Americas, approximately 100,000 children under the age of 5 years die each year due to environmental hazards. Brazil, due to its large size and wide range of environmental challenges, presents numerous hazards to children's health. The aim of this study was to systematically review the scientific literature that describes children's exposures to environmental pollutants in Brazil and their effects on Brazilian children's health. A systematic review of the scientific literature was performed without language restrictions and time of publication (years). The literature search was conducted in the following key resources: PubMed (MEDLINE), Scopus and Web of Science with the MeSH Terms: Environmental exposure AND Brazil (filters: Human, Child [birth to 18 years] and Affiliation Author). The Virtual Health Library was also employed to access the databases Scielo and Lilacs. The search strategy was [DeCS Terms]: Child OR adolescent AND Environmental exposure AND Brazil. Health effects in children associated with exposure to environmental pollutants in Brazil were reported in 74 studies, during the period between 1995 and 2015. The most frequently cited effect was hospital admission for respiratory causes including wheezing, asthma, and pneumonia among children living in areas with high concentrations of air pollutants. A broad spectrum of other health effects possibly linked to pollutants also was found such as prematurity, low birth weight, congenital abnormality (cryptorchidism, hypospadia, micropenis), poor performance in tests of psychomotor and mental development, and behavioral problems. Exposure to pesticides in utero and postnatally was associated with a high risk for leukemia in children Brazil for stricter monitoring of pollutant emissions and for health surveillance programs especially among vulnerable populations such as pregnant women and young children.

Full Text Available O cuidado causa estresse na dinâmica cotidiana da família levando a complicações físicas, mentais e emocionais ao cuidador, perda da liberdade e/ou sobrecarga de cônjuges. Entre março e novembro de 2006, esta pesquisa antropológica examinou o cuidado familiar no contexto da Doença Pulmonar Obstrutiva Crônica (DPOC. Utilizando entrevista etnográfica, narrativa da enfermidade e observação participante objetivou-se descrever a reorganização e a convivência familiar com a evolução e a experiência com a DPOC, a percepção de cuidadores familiares sobre as dificuldades e as limitações vivenciadas junto ao doente e as estratégias de enfrentamento da enfermidade. Participaram do estudo seis cuidadores familiares de baixa renda residentes em bairros urbanos pobres da periferia de Fortaleza, Ceará, Brasil. Da Análise de Conteúdo emergiram as categorias: "dividindo sofrimentos" e "atitudes e comportamentos percebidos e vivenciados pelos cuidadores". As narrativas profundas mostraram a afetação significativa entre os enfermos e seus cuidadores familiares. Apesar da pobreza, violência estrutural, desemprego, preconceito social e baixos salários endêmicos no nordeste brasileiro, os cuidadores descobrem maneiras efetivas de lidar com a cronicidade além de criar estratégias para amenizar o sofrimento causado pela doença.The provision of care causes stress in everyday family dynamics leading to physical, mental and emotional complications in caregivers and spouses' loss of liberty and/or overwork.

Full Text Available Floods in urban areas are responsible for impacts that go from puddles formation to environmental and social disasters. Looking for alternatives to minimize the effects of floods in urban areas, some methodologies have been studied and applied, such as the use of detention basin in high consolidated urban areas. This study analyses the efficiency on flood control of two detention basins, a dry and a wet one. The study approaches both quantitative and qualitative aspects related to runoff from an urban area of Brasilia city, federal district of Brazil. The affluent caught by the detention basins is related to a conventional urban drainage system with a 4.75km2 (dry basin and 6.12km2 (wet basin contribution area. The results showed that the basins can reduce the peak income flow significantly (averaged 62.6% and 74% peak flow reduction, for dry and wet basin, respectively and has positive impact over pollution control, with an average reduction of 1 to 3% for BOD and up to 41 to 74% for Suspended Solids.

2015-08-01

The evolutionary origins of the influenza A(H1N1)pdm09 virus that caused the first outbreak of the 2009 pandemic in Mexico remain unclear, highlighting the lack of swine surveillance in Latin American countries. Although Brazil has one of the largest swine populations in the world, influenza was not thought to be endemic in Brazil's swine until the major outbreaks of influenza A(H1N1)pdm09 in 2009. Through phylogenetic analysis of whole-genome sequences of influenza viruses of the H1N1, H1N2, and H3N2 subtypes collected in swine in Brazil during 2009-2012, we identified multiple previously uncharacterized influenza viruses of human seasonal H1N2 and H3N2 virus origin that have circulated undetected in swine for more than a decade. Viral diversity has further increased in Brazil through reassortment between co-circulating viruses, including A(H1N1)pdm09. The circulation of multiple divergent hemagglutinin lineages challenges the design of effective cross-protective vaccines and highlights the need for additional surveillance.

The developmental state in Brazil: comparative and historical perspectives

Directory of Open Access Journals (Sweden)

BEN ROSS SCHNEIDER

2015-03-01

Full Text Available The record of successful developmental states in East Asia and the partial successes of developmental states in Latin America suggest several common preconditions for effective state intervention including a Weberian bureaucracy, monitoring of implementation, reciprocity (subsidies in exchange for performance, and collaborative relations between government and business. Although Brazil failed to develop the high technology manufacturing industry and exports that have fueled sustained growth in East Asia, its developmental state had a number of important, and often neglected, successes, especially in steel, automobiles, mining, ethanol, and aircraft manufacturing. Where Brazil's developmental state was less successful was in promoting sectors like information technology and nuclear energy, as well as overall social and regional equality. In addition, some isolated initiatives by state governments were also effective in promoting particular local segments of industry and agriculture. Comparisons with East Asia, highlight the central role of state enterprises in Brazil that in effect internalized monitoring and reciprocity and bypassed collaboration between business and government (that was overall rarer in Brazil.

Ethnozoology in Brazil: current status and perspectives.

Alves, Rômulo Rn; Souto, Wedson Ms

2011-07-18

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.

Dengue situation in Brazil by year 2000

Directory of Open Access Journals (Sweden)

Hermann G Schatzmayr

2000-01-01

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

Significant areas of the Brazilian Amazon have been deforested over the past few decades, with fire being the dominant method through which forests and vegetation are cleared. Fires emit large quantities of particulate matter into the atmosphere, degrading air quality and negatively impacting human health. Since 2004, Brazil has achieved substantial reductions in deforestation rates and associated deforestation fires. Here we assess the impact of this reduction on air quality and human health. We show that dry season (August - October) aerosol optical depth (AOD) retrieved by satellite over southwest Brazil and Bolivia is positively related to Brazil's annual deforestation rate (r=0.96, Pannually across South America. Future increases in Brazil's deforestation rates and associated fires may threaten the improved air quality reported here.

Queiroz, Luiz P; Silva Junior, Ariovaldo A

2015-02-01

In Brazil, several epidemiological studies on headache have been produced, most with an emphasis on prevalence and the association of primary headaches with some sociodemographic characteristics of the population. Data on the burden of headache, however, are scarce. The aim of this paper is to review all Brazilian population-based studies on headache, as well as to analyze the Migraine Disability Assessment Score (MIDAS) data collected with the PhD thesis of the senior author (LPQ). A literature review was performed using the keywords ("headache" or "migraine") and ("epidemiology" or "prevalence") and (Brazil). Another part of this paper will look at unpublished data on disability (MIDAS), collected with the prevalence data of the Brazilian nationwide epidemiological study of headache. There are 6 published epidemiological studies of headache in Brazil. The mean 1-year prevalence of headache in Brazil is 70.6%, of migraine 15.8%, of tension-type headache (TTH) 29.5%, and of chronic daily headache (CDH) 6.1%. Disability is significantly higher: in females compared to males; in patients with migraine and CDH compared to patients with TTH; and in those with headaches ≥15 days per month rather than those with episodic headaches. There was also a positive relationship between pain intensity and severity of disability. Patients with higher disability used more both abortive and prophylactic medication. The mean prevalence of headache in Brazil, and some of its subtypes, is similar to the rates described in other countries of the world. Disability is higher in females, in patients with migraine, in individuals with headaches ≥15 days per month, and in those with severe head pain. © 2015 American Headache Society.

Anthropology of health in Brazil: a border discourse.

Science.gov (United States)

Langdon, Esther Jean; Follér, Maj-Lis

2012-01-01

This article traces the development of anthropological research on health in Brazil in light of discussions on modernity/coloniality and world anthropologies. Originating in the 1970s, stimulated by external and internal pressures for scientific production and along with the expansion of graduate programs, a network of anthropologists has consolidated and multiplied in Brazil. We describe the development of research groups, meetings, and publications in order to characterize Brazilian anthropology of health as a research program that distinguishes itself from North Atlantic medical anthropology. We examine the visibility and circulation of references in academic publications to explore the participation of Brazilians in the global discourse and, more specifically, in the North-South dialogue. From a comparative perspective, we argue that anthropological investigations of health reflect a perspective and ethos distinctive to Brazil and its historical and political processes.

Will Brazil's cars go on the wagon?

International Nuclear Information System (INIS)

Homewood, B.

1993-01-01

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

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.

The aim of this article is to present part of the results obtained by the intervention made from the author's Master degree project, which consisted in the development of a set of Astronomy classes for first year of High School students from a private school in the "Distrito Federal", Brasilia, Brazil, making use of a didactical material called mini-planetarium (MP) as the main resource. Using Paulo Freire's contextualization and dialogicity ideas as a theoretical framework guided by these lessons, it was proposed to the students the assembly and application of that resource in a planetarium session. During the project, some subjects such as the apparent trajectory of stars through Brasilia's sky, the location of the cardinal points beginning from the Southern Cross constellation, the color of stars and the stars being seen from a particular place were emphasized. It was found that the students showed an improvement of their understanding about these subjects, as well as a significant excitement with the developed methodology. El objetivo de este trabajo es presentar algunos de los resultados obtenidos en el proyecto de la tesis de maestría del autor, que incluyó el desarrollo de algunas clases de Astronomía, con estudiantes del primer año del bachillerato de una escuela privada del Distrito Federal (Brasilia, Brasil), utilizando como materia prima didáctica el recurso llamado miniplanetario (MP). Utilizando como base teórica orientadora de esas clases las ideas de contextualización y dialógica de Paulo Freire, fue propuesto a los estudiantes el montaje y la utilización de este recurso en una función de planetario. Durante el proyecto, se enfatizaron asuntos tales como la trayectoria aparente de las estrellas del cielo de Brasilia, la ubicación de los puntos cardinales a partir de la constelación de la Cruz del Sur, los colores de las estrellas y las estrellas vistas desde una localidad determinada. Se constató que los estudiantes mostraron una mejora

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.

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

Science.gov (United States)

Soares, Catharina Leite Matos

2012-01-01

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

Review of potential environmental impacts of transgenic glyphosate-resistant soybean in Brazil.

Cerdeira, Antonio L; Gazziero, Dionsio L P; Duke, Stephen O; Matallo, Marcus B; Spadotto, Claudio A

2007-01-01

Transgenic glyphosate-resistant soybeans (GRS) have been commercialized and grown extensively in the Western Hemisphere, including Brazil. Worldwide, several studies have shown that previous and potential effects of glyphosate on contamination of soil, water, and air are minimal, compared to those caused by the herbicides that they replace when GRS are adopted. In the USA and Argentina, the advent of glyphosate-resistant soybeans resulted in a significant shift to reduced- and no-tillage practices, thereby significantly reducing environmental degradation by agriculture. Similar shifts in tillage practiced with GRS might be expected in Brazil. Transgenes encoding glyphosate resistance in soybeans are highly unlikely to be a risk to wild plant species in Brazil. Soybean is almost completely self-pollinated and is a non-native species in Brazil, without wild relatives, making introgression of transgenes from GRS virtually impossible. Probably the highest agricultural risk in adopting GRS in Brazil is related to weed resistance. Weed species in GRS fields have shifted in Brazil to those that can more successfully withstand glyphosate or to those that avoid the time of its application. These include Chamaesyce hirta (erva-de-Santa-Luzia), Commelina benghalensis (trapoeraba), Spermacoce latifolia (erva-quente), Richardia brasiliensis (poaia-branca), and Ipomoea spp. (corda-de-viola). Four weed species, Conyza bonariensis, Conyza Canadensis (buva), Lolium multiflorum (azevem), and Euphorbia heterophylla (amendoim bravo), have evolved resistance to glyphosate in GRS in Brazil and have great potential to become problems.

Brazil built its public health education system through the work of the renowned Oswaldo Cruz Foundation, which established courses across the whole country. The courses eventually became the core curriculum for small schools and now Brazil boasts 40 schools of public health. Foundation President Paulo Buss argues that there are ways that resource-poor countries can improve their public health education.

Entomopathogenic nematodes (EPNs) (Steinernematidae and Heterorhabditidae) can control pests due to the mutualistic association with bacteria that kill the host by septicemia and make the environment favorable for EPNs development and reproduction. The diversity of EPNs in Brazilian soils requires further study. The identification of EPNs, adapted to environmental and climatic conditions of cultivated areas is important for sustainable pest suppression in integrated management programs in agricultural areas of Brazil. The objective was to identify EPNs isolated from agricultural soils with annual, fruit and forest crops in Brazil. Soil samples were collected and stored in 250 ml glass vials. The nematodes were isolated from these samples with live bait traps ([Galleria mellonella L. (Lepidoptera: Pyralidae) larvae]. Infective juveniles were collected with White traps and identified by DNA barcoding procedures by sequencing the D2/D3 expansion of the 28S rDNA region by PCR. EPNs identified in agricultural areas in Brazil were Heterorhabditis amazonensis, Metarhabditis rainai, Oscheios tipulae and Steinernema rarum. These species should be considered pest biocontrol agents in Brazilian agricultural areas.

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

Ferreira, Vanessa Alves; Magalhães, Rosana

2011-04-01

The increase in obesity among women in the lower income bracket in Brazil has been singled out as a priority issue in the field of Public Health today. Concern about future repercussions of obesity in the less privileged groups calls for an in-depth theoretical approach and the energetic definition of public policy for prevention and control of the affliction in these segments. In this respect, the scope of this work is to attempt to pinpoint some analytical categories in the phenomenon of obesity among the underprivileged female population in Brazil. Biological, socioeconomic and cultural factors appear to interact in the dynamics of female obesity in the context of poverty revealing the complexity of this problem. Public policies of job creation, social inclusion and gender equality in the labor market would appear to be more promising ways of tackling obesity in underprivileged females in Brazil.

This paper presents the experience acquired by PETROBRAS Transporte S.A., TRANSPETRO, signaling the crossing of Sao Paulo - Brasilia Pipeline, OSBRA, with the Grande River, important brazilian river that has in this cross section 400 m in width and 10 m of average depth. In sub aquatic inspections carried through by divers to confirm the pipeline's silting condition, evidences of basin format dredging near the pipeline have been identified and, even though it was not sufficient to expose de pipeline, has reduced its covering significantly. This site is an important area of sand extraction, and although the intense works of awareness of local dredging companies to not operate in the pipeline area, TRANSPETRO was surprised by the evidences. In testimonials, local dredge operators complained about difficulties in identifying the pipeline position in nightly operations. Expecting to improve the operational security in the pipeline crossing, a joint project was developed by TRANSPETRO, Brazilian Navy and the dredging companies, with the intention to signal safe area around the submerged pipeline, avoiding dredge operations with the installation of polyethylene floating buoys equipped with night signaling kits and fixed by concrete anchors. Although it was technically simple, the unprecedented proposal in Brazil increased safety in the pipeline operations and made them much safer for the local population and for the environment, in one of the biggest water resources of the Southeastern region of Brazil.

According to the demands of energy saving and carbon emission reduction, the water vs. energy nexus has become a major concern worldwide. Brazil occupies a singular position in the global energy system. A major portion of the Brazilian occupancies has electricity and the energy system expansion that, at first, possesses adequate means for supporting the economic growing may experience some turnovers. The Brazil determination through alternative fuels was a natural choice, given its large hydropower potential and land agricultural base. In the transportation sector Brazil has developed its energy matrix towards an important rate of ethanol and biodiesel. Although those fuels are low carbon emitter, they may probably not be an affordable alternative regarding land use, food security and water footprint. In this way, considering the recent advances in the exploration of oil from Pre-salt (9-15 million barrels) and the discovery of shale gas wells up to 245 tcf, together to unfavorable social and environmental issues associated to biofuels, the Brazilian energy matrix might turn back to the fossil fuels again. These represent challenges to the Brazilian policymakers and how they will be solved will reflect not only in Brazil but also to the world at large.

ABORTION IN BRAZIL: IMPACTS OF ILLEGALITY IN PUBLIC HEALTH

Full Text Available Abortion in Brazil provides public health impacts, mainly due to the high rate of maternal morbidity and mortality, because it most often occurs in an illegal practice and / or unsafe, because of the illegality of abortion in certain situations in the country. Therefore, it is an issue that refers to the various reflections, such as legal, moral, cultural, socio-economic and bioethical. Given the above, the study aims to address about abortion in Brazil and the impacts of illegality in public health. Study of literature review, descriptive and discursive, held in the database SciELO sites and governmental and non-governmental organizations. It was evident that the illegality of abortion in Brazil is harmful to the health of women who resort to unsafe practices and / or illegal, a violation of human rights, the women’s autonomy, as well as providing public health impacts, and sometimes this actually happens because the deficit in quality of care, specifically to sexual and reproductive health, as the actions of Family Planning. It is considered that the way of abortion in Brazil requires modifications, especially with regard to legislative and bioethics conflicts.

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

Consumer choice between ethanol and gasoline: Lessons from Brazil and Sweden

The introduction of flex-fuel vehicles since 2003 has made possible for Brazilian drivers to choose between high ethanol blends or gasoline depending on relative prices and fuel economies. In Sweden, flex-fuel fleets were introduced in 2005. Prices and demand data were examined for both Brazil and Sweden. Bioethanol has been generally the most cost-efficient fuel in Brazil, but not for all states. In any case, consumers in Brazil have opted for ethanol even when this was not the optimal economic choice. In Sweden, a different behavior was observed when falling gasoline prices made E85 uneconomical in late 2008. In a context of international biofuels expansion, the example of E85 in Sweden indicates that new markets could experience different consumer behavior than Brazil: demand falls rapidly with reduced price differences between ethanol and gasoline. At the same time, rising ethanol demand and lack of an international market with multiple biofuel producers could lead to higher domestic prices in Brazil. Once the limit curve is crossed, the consumer might react by shifting back to the usage of gasoline. - Research Highlights: > Brazil and Sweden both have infrastructure for high fuel ethanol blends. > Flex-fuel vehicles enable competition between ethanol and gasoline in fuel markets. > Data suggests that consumers make their fuel choice based mainly on prices. > Consumers in Sweden appear to be more price-sensitive than their Brazilian counterparts. > In the absence of international markets, high ethanol prices may drive consumers back to gasoline.

Sampaio, Jorge Luiz Mello; Gales, Ana Cristina

2016-12-01

During the last 30 years there has been a dissemination of plasmid-mediated β-lactamases in Enterobacteriaceae in Brazil. Extended spectrum β-lactamases (ESBL) are widely disseminated in the hospital setting and are detected in a lower frequency in the community setting. Cefotaximases are the most frequently detected ESBL type and Klebsiella pneumoniae is the predominant species among ESBL producers. Klebsiella pneumoniae carbapenemase-producing Enterobacteriaceae became widely disseminated in Brazil during the last decade and KPC production is currently the most frequent resistance mechanism (96.2%) in carbapenem resistant K. pneumoniae. To date KPC-2 is the only variant reported in Brazil. Polymyxin B resistance in KPC-2-producing K. pneumoniae has come to an alarming rate of 27.1% in 2015 in São Paulo, the largest city in Brazil. New Delhi metallo-β-lactamase was detected in Brazil in 2013, has been reported in different Brazilian states but are not widely disseminated. Antimicrobial resistance in Enterobacteriaceae in Brazil is a very serious problem that needs urgent actions which includes both more strict adherence to infection control measures and more judicious use of antimicrobials.

Positron Emission Tomography (PET) is a highly sensitive and accurate nuclear medicine imaging technology but the major problem of this technique is the use of radioisotopes with short half-life, less than two hours. The production and selling of short half-life radioisotopes used to be monopoly of the Brazilian Government. In 2006, a Constitutional Amendment revoked the state monopoly due to the need for the use of short half-life radioisotopes in nuclear medicine centers very far from the government production facilities. The aim of this study is to describe the current status of short half-life radioisotopes production in Brazil and discuss some licensing process. In Brazil, as has been occurring worldwide, the number of nuclear medicine centers is increasing. Currently there are 123 services performing PET scans in Brazil. There are 14 cyclotrons operating in Brazil. The type of licensing process conducted in Brazil does not take into account the population density of each state, with a free competition model being adopted. Because of this there is a lot of equipment concentrated in the Southeast and no cyclotrons operating in the Northern part of the country. One of the biggest obstacles during the licensing process is the designation of qualified personnel as operation workers and radiation safety officers. The number of cyclotron accelerators and PET/CT equipment increased in recent years. However, a number of external factors such as the distance from the nuclear medicine centers, and qualified personnel have proved crucial for the economic viability of this type of facility.

Carvalho Vieira, Bianca; Martins, Tiago D.

2017-04-01

Shallow landslides and floods are the processes responsible for most material and environmental damages in Brazil. In the last decades, some landslides events induce a high number of deaths (e.g. Over 1000 deaths in one event) and incalculable social and economic losses. Therefore, the prediction of those processes is considered an important tool for land use planning tools. Among different methods the physically based landslide susceptibility models having been widely used in many countries, but in Brazil it is still incipient when compared to other ones, like statistical tools and frequency analyses. Thus, the main objective of this research was to assess the application of some Physically based landslide susceptibility models in Brazil, identifying their main results, the efficiency of susceptibility mapping, parameters used and limitations of the tropical humid environment. In order to achieve that, it was evaluated SHALSTAB, SINMAP and TRIGRS models in some studies in Brazil along with the Geotechnical values, scales, DEM grid resolution and the results based on the analysis of the agreement between predicted susceptibility and the landslide scar's map. Most of the studies in Brazil applied SHALSTAB, SINMAP and to a lesser extent the TRIGRS model. The majority researches are concentrated in the Serra do Mar mountain range, that is a system of escarpments and rugged mountains that extends more than 1,500 km along the southern and southeastern Brazilian coast, and regularly affected by heavy rainfall that generates widespread mass movements. Most part of these studies used conventional topographic maps with scales ranging from 1:2000 to 1:50000 and DEM-grid resolution between 2 and 20m. Regarding the Geotechnical and hydrological values, a few studies use field collected data which could produce more efficient results, as indicated by international literature. Therefore, even though they have enormous potential in the susceptibility mapping, even for comparison

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.

Plant poisonings in livestock in Brazil and South Africa

Full Text Available Information on intoxication of livestock by plants in Brazil, in terms of cause, clinical signs and pathology, is compared with information on livestock poisoning by plants in South Africa. Plant poisoning, including mycotoxicosis, is considered to be one of three major causes of death in livestock in Brazil, which is one of the top beef producing countries in the world, with a cattle population of more than 200 million. Cattle production in South Africa is on a more modest scale, but with some 600 species of plants and fungi known to cause toxicity in livestock, as opposed to some 130 species in Brazil, the risk to livestock in South Africa appears to be much greater. The comparisons discussed in this communication are largely restricted to ruminants.

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

Coccidioidomycosis is a systemic infection caused by Coccidioides spp. The disease is endemic in Brazil but its incidence is underreported as it is not a notifiable disease. This article presents the results of a serologic survey carried out with 229 volunteers in northeast Brazil by the immunodiffusion (ID) test with commercial Coccidioides spp. antigens. The commercial ID test detected 15 individuals without clinical diagnosis of the disease and two individuals in treatment for coccidioidomycosis. Regarding the epidemiological data, most of the positive individuals were male, between 18 and 65 years of age and were engaged in armadillo hunting. Three women who had never participated in armadillo hunts also displayed positive results for coccidioidal antibodies. Besides armadillo hunts, exposure to environmental dust in endemic areas may account for the serologic response detected in the study. The data from this study suggest the importance of performing epidemiological surveys for coccidioidomycosis in order to understand the prevalence of this disease in Brazil.

This creates a challenge for the evaluation of its prevalence and its direct or indirect impact on the quality of life of elderly populations of different races and ethnicities. Furthermore, no studies as yet have analyzed these variables in populations of elderly subjects of the "quilombola" ethnic group. Objective: We aimed to verify the association between sarcopenia and quality of life in quilombola elderly using the Baumgartner and the European Working Group on Sarcopenia in Older People (EWGSOP criteria. Methods: This was a cross-sectional study of 70 male and female participants (mean age: 65.58±6.67 years. Quality of life was evaluated using the multidimensional 36-item Short-Form Health Survey (SF-36 of the Medical Outcomes Study. Sarcopenia was diagnosed according to the Baumgartner cutoff for appendicular skeletal muscle mass and the criteria recommended by the EWGSOP. Muscle mass and fat mass percentages were analyzed by dual-energy X-ray absorptiometry, while handgrip strength (HGS was evaluated using a hand-held dynamometer. Physical performance was assessed through a gait speed test. Results: The prevalence of sarcopenia was 15% according to the Baumgartner cutoff and 10% according to EWGSOP criteria. Quilombola elderly classified as physically active or very active were at least six times less

Lorena A. Nunes

2012-09-01

Full Text Available The morphometrics of the honey bee Apis mellifera L., 1758 has been widely studied mainly because this species has great ecological importance, high adaptation capacity, wide distribution and capacity to effectively adapt to different regions. The current study aimed to investigate the morphometric variations of wings and pollen baskets of honey bees Apis mellifera scutellata Lepeletier, 1836 from the five regions in Brazil. We used geometric morphometrics to identify the existence of patterns of variations of shape and size in Africanized honey bees in Brazil 16 years after the classic study with this species, allowing a temporal and spatial comparative analysis using new technological resources to assess morphometrical data. Samples were collected in 14 locations in Brazil, covering the five geographical regions of the country. The shape analysis and multivariate analyses of the wing allowed to observe that there is a geographical pattern among the population of Apis mellifera in Brazil. The geographical variations may be attributed to the large territorial extension of the country in addition to the differences between the bioregions.

Status of uranium in Brazil

Uranium exploration in Brazil was started in 1952 by the Brazilian National Research Council. This led to the discovery of the first uranium deposits in Pocos de Caldas and Jacobina. These activities was later continued by the National Energy Commission/Comissao Nacional de Energia Nuclear (CNEN), formed in 1962. The founding of NUCLEBRAS at the end of 1974 marked the increasing effort of the country's uranium exploration programme. At this time only the Pocos de Caldas deposit was known with measurable resources. Due to the reorganization of the Brazilian nuclear programme in 1988, all uranium exploration in the country was stopped. By then, eight areas with uranium reserves has been identified. Brazil uranium resources in the RAR category at ≤ $80/kg U cost range are estimated to be 162,000 tonnes U, out of which 56,100 tonnes are in the ≤ $40/kg U cost range. Additional resources in the EAR-I category and the cost range ≤ 80/kg U are in the order of 100,200 tonnes U. The first production of uranium in Brazil, at the Osamu Utsumi mine (Pocos de Caldas deposit), started in 1982. Because of escalated costs and reduced demand, this activity was put on stand-by status between 1990 and 1992. The mine was restarted in 1993, but was stopped again in October 1995. The cumulative production of the mine to 1996 was 1241 tonnes U. The Lagoa Real deposit is currently being prepared as a new producing mine. (author)

Tackling drug and alcohol misuse in Brazil: priorities and challenges for nurses.

Rassool, G H; Villar-Luis, M

2004-12-01

To provide an overview of the extent of drug and alcohol misuse in Brazil and the policies and approaches in tackling substance misuse. An examination of the challenges facing the nursing profession in working with substance misusers is presented. Alcohol, cocaine, and cannabis are the most commonly misused psychoactive substances in Brazil. One of the biggest public health problems is the interface between the misuse of psychoactive substances and HIV prevalence and other sexually transmitted diseases. Findings from a recent study suggest that undergraduate nurses in Brazil are not adequately prepared in the care and management of substance misuse problems. The nursing profession in Brazil faces numerous challenges in the development of professional competence of nurses in this field. A strategy proposed is the creation of regional centres in Brazil to study the integration of substance use and misuse in the nursing undergraduate curriculum and the giving of specific support in teaching and research to nurse teachers. Nurses have a key role to play in the early recognition, assessment, prevention, and treatment of substance misuse.

Instrumental neutron activation analysis was the analytical technique used in this study. Results indicate that the concentrations of Se and Ba varied greatly among the Brazil nut samples analyzed. This large variability may be related to the soil characteristics from which the nuts were produced. An inverse correlation was observed between the concentrations of Se and Ba. On the other hand, the concentrations of Zn and Mn did not show significant differences among these samples. (author)

Consumer choice between ethanol and gasoline: Lessons from Brazil and Sweden

International Nuclear Information System (INIS)

Pacini, Henrique; Silveira, Semida

2011-01-01

The introduction of flex-fuel vehicles since 2003 has made possible for Brazilian drivers to choose between high ethanol blends or gasoline depending on relative prices and fuel economies. In Sweden, flex-fuel fleets were introduced in 2005. Prices and demand data were examined for both Brazil and Sweden. Bioethanol has been generally the most cost-efficient fuel in Brazil, but not for all states. In any case, consumers in Brazil have opted for ethanol even when this was not the optimal economic choice. In Sweden, a different behavior was observed when falling gasoline prices made E85 uneconomical in late 2008. In a context of international biofuels expansion, the example of E85 in Sweden indicates that new markets could experience different consumer behavior than Brazil: demand falls rapidly with reduced price differences between ethanol and gasoline. At the same time, rising ethanol demand and lack of an international market with multiple biofuel producers could lead to higher domestic prices in Brazil. Once the limit curve is crossed, the consumer might react by shifting back to the usage of gasoline. - Research highlights: → Brazil and Sweden both have infrastructure for high fuel ethanol blends. → Flex-fuel vehicles enable competition between ethanol and gasoline in fuel markets. → Data suggests that consumers make their fuel choice based mainly on prices. → Consumers in Sweden appear to be more price-sensitive than their Brazilian counterparts. → In the absence of international markets, high ethanol prices may drive consumers back to gasoline.

Institutional framework changes in Brazil's energy industries

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

2009-01-01

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

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.

Energy trends and the water-energy binomium for Brazil

Full Text Available According to the demands of energy saving and carbon emission reduction, the water vs. energy nexus has become a major concern worldwide. Brazil occupies a singular position in the global energy system. A major portion of the Brazilian occupancies has electricity and the energy system expansion that, at first, possesses adequate means for supporting the economic growing may experience some turnovers. The Brazil determination through alternative fuels was a natural choice, given its large hydropower potential and land agricultural base. In the transportation sector Brazil has developed its energy matrix towards an important rate of ethanol and biodiesel. Although those fuels are low carbon emitter, they may probably not be an affordable alternative regarding land use, food security and water footprint. In this way, considering the recent advances in the exploration of oil from Pre-salt (9-15 million barrels and the discovery of shale gas wells up to 245 tcf, together to unfavorable social and environmental issues associated to biofuels, the Brazilian energy matrix might turn back to the fossil fuels again. These represent challenges to the Brazilian policymakers and how they will be solved will reflect not only in Brazil but also to the world at large.

Materno-infantilism, feminism and maternal health policy in Brazil.

Science.gov (United States)

Diniz, Simone

2012-06-01

In the last days of 2011, President of Brazil Dilma Rousseff issued a provisional measure (or draft law) entitled "National Surveillance and Monitoring Registration System for the Prevention of Maternal Mortality" (MP 557), as part of a new maternal health programme. It was supposed to address the pressing issue of maternal morbidity and mortality in Brazil, but instead it caused an explosive controversy because it used terms such as nascituro (unborn child) and proposed the compulsory registration of every pregnancy. After intense protests by feminist and human rights groups that this law was unconstitutional, violated women's right to privacy and threatened our already limited reproductive rights, the measure was revised in January 2012, omitting "the unborn child" but not the mandatory registration of pregnancy. Unfortunately, neither version of the draft law addresses the two main problems with maternal health in Brazil: the over-medicalisation of childbirth and its adverse effects, and the need for safe, legal abortion. The content of this measure itself reflects the conflictive nature of public policies on reproductive health in Brazil and how they are shaped by close links between different levels of government and political parties, and religious and professional sectors.

2014-01-01

Brazil is a country of continental dimensions that, over the last 3 decades, has been making increased efforts to develop effective public policies for controlling the use of both licit and illicit psychoactive substances. In the case of licit drugs, Brazil was a pioneer in following the guidance of the World Health Organization for tobacco control and has witnessed surprising results relating to reduction of smoking prevalence and correlated morbidity and mortality. Today, Brazil has a national structure for organizing, applying, and monitoring laws relating to tobacco. However, in the field of illicit drugs, with crack consumption as a paradigm, the situation is the opposite: its use has been increasing year by year and is being consumed at increasingly young ages and by all social classes. Thus, it is becoming an enormous challenge for public policies relating to prevention and treatment. In this context, the aim of this article is to present a review of the epidemiological data relating to tobacco and crack use in Brazil, with an analysis on the impact of public policies for controlling consumption over recent years. Despite the efforts made over the last 3 decades, Brazil still has a long way to go in order to construct a consistent and effective national drugs policy.

The analysis is conducted through a static General Equilibrium and Microsimulation Model of Brazil, calibrated with the PNAD 2001 data. The model comprises 112,055 Brazilian households and 263,938 adults, distinguishing 42 activities, 52 commodities, and 27 regions. The FTAA formation is simulated, and its impacts upon poverty and income distribution in Brazil analyzed. Results point to the fact that even a large shock like the one simulated wouldn't have a strong impact on poverty reduction in Brazil, although the results are concentrated on the poorest households.Este trabalho analisa os efeitos potenciais da formação da ALCA sobre os níveis de pobreza e distribuição de renda no Brasil. A análise é conduzida através de um Modelo Aplicado de Equilíbrio Geral e de Micro-simulação estático, calibrado com os dados da PNAD 2001. O modelo distingue na sua estrutura 112.055 domicílios e 263.938 adultos, 42 atividades produtivas, 52 produtos, e 27 regiões. Os resultados apontam para o fato de que mesmo mudanças tarifárias grandes como as aqui simuladas não trariam um forte impacto sobre a pobreza no Brasil, embora os resultados estejam concentrados nos domicílios mais pobres.

To describe foods consumed away from home and associated factors in Brazil. The study was based on the National Dietary Survey which was conducted among residents aged over 10 years old in 24% of households participating in the Household Budget Survey in 2008-2009 (n = 34,003). The consumption of food and beverages was collected through records of foods consumed, type of preparation, quantity, time and food source (inside or outside home). The frequency with which individuals consumed food away from home was calculated according to age, gender, income, household area location, family size, presence of children at home and age of head of household in Brazil and in each Brazilian region. Specific sampling weight and effect of the sampling design were considered in the analyses. Consumption of food away from home in Brazil was reported by 40% of respondents, varying from 13% among the elderly in the Midwest Region to 51% among adolescents in the Southeast. This percentage decreased with age and increased with income in all regions of Brazil and was higher among men and in urban areas. Foods with the highest percentage of consumption outside home were alcoholic beverages, baked and fried snacks, pizza, soft drinks and sandwiches. Foods consumed away from home showed a predominance of high energy content and poor nutritional content, indicating that the consumption of foods away from home should be considered in public health campaigns aimed at improving Brazilians' diet.

Medical and agricultural entomology in Brazil: a historical approach.

Science.gov (United States)

Benchimol, J L

2008-12-01

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.

In 1990 the national health services in the United Kingdom and Sweden started to split up in internal markets with purchasers and providers.

1991-01-01

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

The aim of this study was to describe 1 the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (RECs and the National Research Ethics Committee (Comissão Nacional de Ética em Pesquisa, CONEP in Brazil from 2007 to 2011 and 2 the diseases most frequently studied in Brazilian states in clinical trials approved in the country from 2009 to 2012, based on information from an Anvisa databank. Two databases were used: 1 the National Information System on Research Ethics Involving Human Beings (Sistema Nacional de Informação Sobre Ética em Pesquisa envolvendo Seres Humanos, SISNEP and 2 Anvisa's Clinical Research Control System (Sistema de Controle de Pesquisa Clínica, SCPC. Data from the SCPC indicated an increase of 32.7% in the number of clinical trials submitted to Anvisa, and data from the SISNEP showed an increase of 69.9% in those approved by RECs and CONEP (from 18 160 in 2007 to 30 860 in 2011. Type 2 diabetes (26.0% and breast cancer (20.5%-related to the main causes of mortality in Brazil-were the two most frequently studied diseases. The so-called “neglected diseases,” such as dengue fever, were among the least studied diseases in approved clinical trials, despite their significant impact on social, economic, and health indicators in Brazil. Overall, the data indicated 1 a clear trend toward more research involving human beings in Brazil, 2 good correspondence between diseases most studied in clinical trials approved by Anvisa and the main causes of death in Brazil, and 3 a low level of attention to neglected diseases, an issue that should be considered in setting future research priorities, given their socioeconomic and health effects.

The crystallization of the brazil nut allergen Ber e 2 is reported. Peanut and tree-nut allergies have attracted considerable attention because of their frequency and their lifelong persistence. Brazil-nut (Bertholletia excelsa) allergies have been well documented and the 11S legumin-like seed storage protein Ber e 2 (excelsin) is one of the two known brazil-nut allergens. In this study, Ber e 2 was extracted from brazil-nut kernels and purified to high purity by crystalline precipitation and gel-filtration chromatography. Well diffracting single crystals were obtained using the hanging-drop vapour-diffusion method. A molecular-replacement structural solution has been obtained. Refinement of the structure is currently under way.

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.

Characterization and genesis of waterfalls of the Presidente Figueiredo region, Northeast State of Amazonas, Brazil

Directory of Open Access Journals (Sweden)

AFONSO C. R. NOGUEIRA

2001-06-01

Full Text Available The waterfalls of the Presidente Figueiredo municipality represent a fascinating natural scenery of northeast state of Amazonas, northern Brazil. The falls, generally less than 10m high, are developed on siliciclastic rocks of the Nhamundá (Lower Silurian, and Manacapuru (Upper Silurian - Lower Devonian formations. Morphological and structural analyses of these features indicate that most of them originated through Quaternary neotectonics and are installed in NE-trending normal fault escarpments. Waterfalls also developed within pseudokarstic features, but are less frequent. The origin of the Presidente Figueiredo waterfalls probably goes back to the Neogene, when the region was submitted to laterization processes associated with a humid climate and a dense rainforest. These conditions favored the development of caves in quartzarenites of the Nhamundá Formation. During the Quaternary, the region was subjected to NE-trending normal faulting which displaced laterite layers, rivers and streams giving rise to waterfalls. These climatic and tectonic phenomena promoted intense relief dissection, as indicated by fault escarpment retreat and cave dismantlement, responsible for the present-day morphologic configuration.As cachoeiras da região de Presidente Figueiredo constituem um dos mais fascinantes cenários naturais do nordeste do Estado do Amazonas, norte do Brasil.

The first confirmed case of Zika virus infection in the Americas was reported in Northeast Brazil in May 2015, although phylogenetic studies indicate virus introduction as early as 2013. Zika rapidly spread across Brazil and to more than 50 other countries and territories on the American continent. The Aedes aegypti mosquito is thought to be the principal vector responsible for the widespread transmission of the virus. However, sexual transmission has also been reported. The explosively emerging epidemic has had diverse impacts on population health, coinciding with cases of Guillain-Barré Syndrome and an unexpected epidemic of newborns with microcephaly and other neurological impairments. This led to Brazil declaring a national public health emergency in November 2015, followed by a similar decision by the World Health Organization three months later. While dengue virus serotypes took several decades to spread across Brazil, the Zika virus epidemic diffused within months, extending beyond the area of permanent dengue transmission, which is bound by a climatic barrier in the south and low population density areas in the north. This rapid spread was probably due to a combination of factors, including a massive susceptible population, climatic conditions conducive for the mosquito vector, alternative non-vector transmission, and a highly mobile population. The epidemic has since subsided, but many unanswered questions remain. In this article, we provide an overview of the discovery of Zika virus in Brazil, including its emergence and spread, epidemiological surveillance, vector and non-vector transmission routes, clinical complications, and socio-economic impacts. We discuss gaps in the knowledge and the challenges ahead to anticipate, prevent, and control emerging and re-emerging epidemics of arboviruses in Brazil and worldwide.

Brazil is one of the world's largest producers of alcohol from biomass at low cost and is responsible for more than 1 million direct jobs. In 1973, the Brazilian Program of Alcohol (Proalcool) stimulated the creation of a bioethanol industry that has led to large economic, social, and scientific improvements. In the year 1984, 94.5% of Brazil's cars used bioethanol as fuel. In 2003/2004, 350.3 million of sugarcane produced 24.2 million t of sugar and 14.4 billion L of ethanol for an average 4.3 million cars using ethanol. Since its inception, cumulative investment in Proalcool totals US$11 billion, and Brazil has saved US$27 billion in oil imports. The ethanol production industry from sugarcane gene-rates 152 times more jobs than would have been the case if the same amount of fuel was produced from petroleum, and the use of ethanol as a fuel is advantageous for environmental reasons. In 2003, one of the biggest Brazilian ethanol industries started consuming 50% of the residual sugarcane bagasse to produce electrical energy (60 MW), a new alternative use of bioenergy for the Brazilian market. Other technologies for commercial uses of bagasse are in development, such as in the production of natural fibers, sweeteners (glucose and xylitol), single-cell proteins, lactic acid, microbial enzymes, and many other products based on fermentations (submerged and semisolid). Furthermore, studies aimed at the increase in the biosynthesis of sucrose and, consequently, ethanol productivity are being conducted to understand the genetics of sugarcane. Although, at present, there remain technical obstacles to the economic use of some ethanol industry residues, several research projects have been carried out and useful data generated. Efficient utilization of ethanol industry residues has created new opportunities for new value-added products, especially in Brazil, where they are produced in high quantities.

“Almost invisible scars”: medical tourism to Brazil.

Science.gov (United States)

Edmonds, Alexander

2011-01-01

Along with a handful of other nations in the developing world, Brazil has emerged as a top destination for medical tourism. Drawing on the author's ethnographic fieldwork in plastic surgery wards, this article examines diverse factors - some explicitly promoted in medical marketing and news sources, others less visible - contributing to Brazil's international reputation for excellence in cosmetic plastic surgery. Brazil's plastic surgery residency programs, some of which are housed within its public health system, attract overseas surgeons, provide ample opportunities for valuable training in cosmetic techniques, and create a clinical environment that favors experimentation with innovative techniques. Many graduates of these programs open private clinics that, in turn, attract overseas patients. High demand for Brazilian plastic surgery also reflects an expansive notion of female health that includes sexual realization, mental health, and cosmetic techniques that manage reproduction. Medical tourism is sometimes represented as being market-driven: patients in wealthier nations travel to obtain quality services at lower prices. This article ends by reflecting on how more complex local and transnational dynamics also contribute to demand for elective medical procedures such as cosmetic surgery.

Strategic Behavior Analysis of Small Business in Brazil

Peter Bent Hansen

2014-07-01

Full Text Available Over recent years, small businesses have been the target of public and private investment in Brazil due to the appreciation of their economic and social impact. The growth of small businesses in Brazil has stimulated a demand for greater knowledge and a broader understanding of their peculiarities. Hence, this paper aims to propose a framework for analyzing the strategic behavior for small businesses. To test the suitability of this analytical framework, qualitative research was conducted based on descriptive and exploratory case studies involving three small companies in the construction sector in the Rio Grande do Sul state, Brazil. The results show that: (i based on the proposed analytical structure it was possible to identifythe idiosyncrasies and the conflicts between strategy, structure and processes in such firms; (ii the strategic behavior ofthe firms is not stable, since they demonstrate the ability to change the prevailing strategic behavior based on strategicdecisions that reinforce the strategic typologies studied and; (iii it is possible to identify opportunities to strengthen certainstrategic behavior of firms.

Serological Evidence of Orthopoxvirus Circulation Among Equids, Southeast Brazil

Directory of Open Access Journals (Sweden)

Iara A. Borges

2018-03-01

Full Text Available Since 1999 Vaccinia virus (VACV outbreaks involving bovines and humans have been reported in Brazil; this zoonosis is known as Bovine Vaccinia (BV and is mainly an occupational disease of milkers. It was only in 2008 (and then again in 2011 and 2014 however, that VACV was found causing natural infections in Brazilian equids. These reports involved only equids, no infected humans or bovines were identified, and the sources of infections remain unknown up to date. The peculiarities of Equine Vaccinia outbreaks (e.g., absence of human infection, the frequently shared environments, and fomites by equids and bovines in Brazilian farms and the remaining gaps in BV epidemiology incited a question over OPV serological status of equids in Brazil. For this report, sera from 621 equids - representing different species, ages, sexes and locations of origin within Minas Gerais State, southeast Brazil – were examined for the presence of anti-Orthopoxvirus (OPV antibodies. Only 74 of these were sampled during an Equine Vaccinia outbreak, meaning some of these specific animals presented typical lesions of OPV infections. The majority of sera, however, were sampled from animals without typical signs of OPV infection and during the absence of reported Bovine or Equine Vaccinia outbreaks. Results suggest the circulation of VACV among equids of southeast Brazil even prior to the time of the first VACV outbreak in 2008. There is a correlation of OPVs outbreaks among bovines and equids although many gaps remain to our understanding of its nature. The data obtained may even be carefully associated to recent discussion over OPVs history. Moreover, data is available to improve the knowledge and instigate new researches regarding OPVs circulation in Brazil and worldwide.

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

To describe suicide rates by county size in the five geopolitical areas of Brazil. This was an ecological, descriptive study of suicide deaths in Brazil that occurred among the population 10 years of age and older in 2004-2010. Data were obtained from the National Mortality Information System of Brazil. Counties were defined by size as: very large (200,000+), large (interval were used to compare suicide risk between groups and the reference. The national, average suicide mortality rate was 5.7 deaths/100,000 inhabitants. Except in the North and North-East, suicide mortality rates increased from the very large (> 200,000) to the micro counties ( 30 deaths per 100,000). At highest risk were micro counties in the South (13.6 deaths per 100,000), with elderly males (60+ years, 31.4) and males 40-59 years (31.3) being the sex/age group with the highest rates. To reduce suicide mortality in Brazil, public health authorities must support mental health training in small cities and multi-professional interventions among the indigenous peoples. In addition, the causes behind underreporting of suicide deaths must be resolved in several areas.

Extreme Water Deficit in Brazil Detected from Space

Science.gov (United States)

Vieira Getirana

2016-01-01

Extreme droughts have caused significant socioeconomic and environmental damage worldwide. In Brazil, ineffective energy development and water management policies have magnified the impacts of recent severe droughts, which include massive agricultural losses, water supply restrictions, and energy rationing. Spaceborne remote sensing data advance our understanding of the spatiotemporal variability of large-scale droughts and enhance the detection and monitoring of extreme water-related events. In this study, data derived from the Gravity Recovery and Climate Experiment (GRACE) mission are used to detect and quantify an extended major drought over eastern Brazil and provide estimates of impacted areas and region-specific water deficits. Two structural breakpoint detection methods were applied to time series of GRACE-based terrestrial water storage anomalies (TWSA), determining when two abrupt changes occurred. One, in particular, defines the beginning of the current drought. Using TWSA, a water loss rate of 26.1 cmyr21 over southeastern Brazil was detected from 2012 to 2015. Based on analysis of Global Land Data Assimilation System(GLDAS) outputs, the extreme drought is mostly related to lower-than-usual precipitation rates, resulting in high soil moisture depletion and lower-than-usual rates of evapotranspiration. A reduction of 2023 of precipitation over an extended period of 3 years is enough to raise serious water scarcity conditions in the country. Correlations between monthly time series of both grid-based TWSA and ground-based water storage measurements at 16 reservoirs located within southeastern Brazil varied from 0.42 to 0.82. Differences are mainly explained by reservoir sizes and proximity to the drought nucleus.

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

Full Text Available http://dx.doi.org/10.5007/2175-7984.2014v13n28p199 Contentious politics helps individuals and groups with limited political voice to place their ideas and interests on the political agenda. Contentious politics were long thought to occur when politically marginalized group had no other means to advance their political agenda. The June 2013 social mobilization in Brazil caught most political observers by surprise, especially given the creation of a large, wide-spread participatory architecture (national conferences, councils, participatory budgeting. The innovative institutions emerging in Brazil created a policy environment in which millions of citizens have regular access to state policymaking bodies. How does the institutionalization of a broader network of participatory institutions make it easier for citizens to engage in contentious politics? In what ways does this institutionalization make it more difficult for some citizens to engage in contentious politics? In what ways has the vast network of participatory institutions been largely irrelevant to how citizens use contentious politics? This article explore how the institutionalization of an extensive participatory democracy system in Brazil alters the incentive structures that encourage citizens to engage in contentious collective action.

Scientometrical review of Dinoflagellate studies in Brazil

2018-06-01

Full Text Available ABSTRACT Scientific production in developing countries is currently increasing, but there is still an unbalanced distribution of scientific production between developed and developing countries. With the need to elucidate disparities in scientific production, this paper aims to review publications on dinoflagellates in Brazil by discussing spatial and temporal trends. A search for papers referring to dinoflagellates was performed in the Scopus database up to the year of 2016. A total of 125 papers were found, but only 106 were selected according to established criteria. A linear regression was used to evaluate the increasing temporal trend in production and non-parametric ANOVA for comparisons among study categories. Dinoflagellate and toxic taxa-based publications have increased from 1990 to 2016 for Brazil, yet a discrepancy in performance with other countries is evident. There is a constant increase in the number of functional ecology studies focusing on toxin-producing species related to blooms. The spatial distribution of production in Brazil revealed that the Southeast and South regions are the most productive, where there more graduate programs and advanced research centers. Investments in this ecological subject are fundamental to the management of biodiversity, and a call for more equal resource distribution in developing countries is imperative.

Brazil's energy supply system is relatively low in CO{sub 2} emissions. However, the security of energy supply is poor, posing a risk to the growth of the Brazilian economy. The great challenge confronting Brazil is to improve the security of its energy supply at low cost and if possible without increasing CO{sub 2} emissions or creating social problems. Modern energy efficiency technologies and renewable energy resources could make an important contribution to this end. This defines the approach of the energy programme launched by the GTZ on behalf of the German Federal Government.

Soil-transmitted helminth (STH) infections are widely distributed in tropical and subtropical areas, including Brazil. We performed a nationwide population-based study including all deaths in Brazil from 2000 to 2011, in which STHs (ascariasis, trichuriasis and/or hookworm infection) were mentioned on death certificates, either as underlying or as associated causes of death. Epidemiological characteristics, time trends and spatial analysis of STH-related mortality were analysed. STHs was identified on 853/12 491 280 death certificates: 827 (97·0%) deaths related to ascariasis, 25 (2·9%) to hookworm infections, and 1 (0·1%) to trichuriasis. The average annual age-adjusted mortality rate was 0·34/1 000 000 inhabitants (95% confidence interval: 0·27-0·44). Females, children Brazil, a considerable number of deaths is caused by STHs, with ascariasis responsible for the vast majority. There were marked regional differences, affecting mainly children and vulnerable populations.

Oliveira, Mauro C L M; Dos Santos, Maurício B; Loebmann, Daniel; Hartman, Alexandre; Tozetti, Alexandro M

2013-01-01

This study aimed to verify the relationship between habitat and the composition of anuran species in dune and restinga habitats in southernmost Brazil. The habitats were sampled between April 2009 and March 2010 using pitfalls with drift fence. We have captured 13,508 individuals of 12 anuran species. Species richness was lower in the dunes and dominance was higher in the resting. Apparently the less complex plant cover, water availability, and wide daily thermal variation in dunes act as an environmental filter for frogs. This hypothesis is reinforced by the fact that the most abundant species (Physalaemus biligonigerus and Odonthoprynus maisuma) bury themselves in the sand, minimizing these environmental stresses. Despite being in the Pampa biome, the studied community was more similar to those of coastal restinga environment of southeast Brazil than with other of the Pampa biome. The number of recorded species is similar to those observed in other open habitats in Brazil, showing the importance of adjacent ones to the shoreline for the maintenance of the diversity of anurans in southernmost Brazil.

Future oil production in Brazil-Estimates based on a Hubbert model

International Nuclear Information System (INIS)

Szklo, Alexandre; Machado, Giovani; Schaeffer, Roberto

2007-01-01

This paper forecasts oil production in Brazil, according to the Hubbert model and different probabilities for adding reserves. It analyzes why the Hubbert model might be more appropriate to the Brazilian oil industry than that of Hotelling, as it implicitly emphasizes the impacts of information and depletion on the derivative over time of the accumulated discoveries. Brazil's oil production curves indicate production peaks with a time lag of more than 15 years, depending on the certainty (degree of information) associated with the reserves. Reserves with 75% certainty peak at 3.27 Mbpd in 2020, while reserves with 50% certainty peak at 3.28 Mbpd in 2028, and with 30% certainty peak at 3.88 Mbpd in 2036. These findings show that Brazil oil industry is in a stage where the positive impacts of information on expanding reserves (mainly through discoveries) may outstrip the negative impacts of depletion. The still limited number of wells drilled by accumulated discoveries also explain this assertion. Being a characteristic of frontier areas such as Brazil, this indicates the need for ongoing exploratory efforts

Brazil nut harvesting in Peruvian Amazonia from the perspective of ecosystem services

Directory of Open Access Journals (Sweden)

Risto Kalliola

2011-01-01

Full Text Available Brazil nuts are harvested from the primary rainforests in the Amazonian lowlands as a direct form of sustainably using the region’s biological resources. We analyze the ecological economics of Brazil nut production in the Peruvian region of Madre de Dios where nut extraction occurs on hundreds of small-holder concessions operating under long-term agreements. This activity sustains locally important economies that suffer from small volumes and high seasonality. The size and the remoteness of the NTFP concession determine much of its profitability to concessionaires. Seasonality of the harvest generates short-term income peaks for the majority of collectors. The fragility of the Brazil nut economy in the region is compounded by volatile market prices and the overall development pressures in Amazonia, which usually involve deforestation. Although the current regulatory mechanisms in Peru encourage long-term Brazil nut production in concessions, the income level is seldom high enough to help concession-owners to rise from poverty. Auxiliary financial support based on compensations for the non-valued ecosystem services provided by the forest-covered Brazil nut concessions could change the picture. Funds for these could come from international instruments like those of carbon emission control or debt for nature swaps. Green marketing could be developed to consider payments supporting ecosystem values as well as mechanisms supporting indigenous communities working with Brazil nuts. Appropriate indicators are needed to optimize those management, policy and trading conditions that best help to preserve the invaluable ecosystem functions and services.

Yared Santa-Ana-Tellez

Full Text Available BACKGROUND: In Latin American countries over-the-counter (OTC dispensing of antibiotics is common. In 2010, both Mexico and Brazil implemented policies to enforce existing laws of restricting consumption of antibiotics only to patients presenting a prescription. The objective of the present study is therefore to evaluate the impact of OTC restrictions (2010 on antibiotics consumption in Brazil and Mexico. METHODS AND FINDINGS: Retail quarterly sales data in kilograms of oral and injectable antibiotics between January 2007 and June 2012 for Brazil and Mexico were obtained from IMS Health. The unit of analysis for antibiotics consumption was the defined daily dose per 1,000 inhabitants per day (DDD/TID according to the WHO ATC classification system. Interrupted time series analysis was conducted using antihypertensives as reference group to account for changes occurring independently of the OTC restrictions directed at antibiotics. To reduce the effect of (a seasonality and (b autocorrelation, dummy variables and Prais-Winsten regression were used respectively. Between 2007 and 2012 total antibiotic usage increased in Brazil (from 5.7 to 8.5 DDD/TID, +49.3% and decreased in Mexico (10.5 to 7.5 DDD/TID, -29.2%. Interrupted time series analysis showed a change in level of consumption of -1.35 DDD/TID (p<0.01 for Brazil and -1.17 DDD/TID (p<0.00 for Mexico. In Brazil the penicillins, sulfonamides and macrolides consumption had a decrease in level after the intervention of 0.64 DDD/TID (p = 0.02, 0.41 (p = 0.02 and 0.47 (p = 0.01 respectively. While in Mexico it was found that only penicillins and sulfonamides had significant changes in level of -0.86 DDD/TID (p<0.00 and -0.17 DDD/TID (p = 0.07. CONCLUSIONS: Despite different overall usage patterns of antibiotics in Brazil and Mexico, the effect of the OTC restrictions on antibiotics usage was similar. In Brazil the trend of increased usage of antibiotics was tempered after the OTC restrictions; in

This study updates the geographic distributions of phlebotomine species in Central-West Brazil and analyses the climatic factors associated with their occurrence. The data were obtained from the entomology services of the state departments of health in Central-West Brazil, scientific collections and a literature review of articles from 1962-2014. Ecological niche models were produced for sandfly species with more than 20 occurrences using the Maxent algorithm and eight climate variables. In all, 2,803 phlebotomine records for 127 species were analysed. Nyssomyia whitmani, Evandromyia lenti and Lutzomyia longipalpis were the species with the greatest number of records and were present in all the biomes in Central-West Brazil. The models, which were produced for 34 species, indicated that the Cerrado areas in the central and western regions of Central-West Brazil were climatically more suitable to sandflies. The variables with the greatest influence on the models were the temperature in the coldest months and the temperature seasonality. The results show that phlebotomine species in Central-West Brazil have different geographical distribution patterns and that climate conditions in essentially the entire region favour the occurrence of at least one Leishmania vector species, highlighting the need to maintain or intensify vector control and surveillance strategies.

Diffusion of new automotive technologies for improving energy efficiency in Brazil's light vehicle fleet

Bastin, Cristina; Szklo, Alexandre; Rosa, Luiz Pinguelli

2010-01-01

Historically, Brazil has promoted the development and sales of light duty vehicles running on ethanol (firstly, ethanol-dedicated cars, and recently flexfuel cars). In the 1990s, the country also favored the sales of compact cars to middle and low-income classes. However, in the last years, the profile of vehicles sold in Brazil has converged towards larger and less-efficient vehicles. In 2008, Brazil launched the vehicle labeling program. Based on the outcomes of the historical programs oriented towards the development of automotive innovations, and on a survey conducted with the country's main auto makers, this article evaluates whether the vehicle labeling program will both improve the energy efficiency of light vehicles, and introduce new technologies. Our results indicate that, despite its virtuous intentions, the program will not control the tendency of rising fuel consumption of passenger cars sold in Brazil. Therefore, other policies are needed to boost innovations in Brazil's automotive industry. (author)

[Toxicity and apple production in southern Brazil].

Science.gov (United States)

Klanovicz, Jó

2010-03-01

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

Who pays and who gains from fuel policies in Brazil?

Khanna, Madhu; Nuñez, Hector M.; Zilberman, David

2016-01-01

Brazil has pursued a mix of policy interventions in the fuel sector to achieve multiple objectives of economic and social development, promoting biofuels and reducing dependence on oil. We develop an economic framework to provide insight on the fuel policy choices in Brazil and to analyze the trade-offs they have engendered in the fuel and sugar sectors. We also examine their distributional impacts on producers and consumers in the sugar, oil and biofuel sectors and on government revenues. Additionally, we undertake a normative analysis for the purpose of comparing the welfare and environmental impacts of existing policies with those justified by the goal of maximizing social welfare and addressing market failure. The ex-post analysis of the outcomes for different stakeholders in the fuel and sugar sectors provides insights on the likely political-economic factors guiding policy choices. We find that the status quo policies are likely to have been motivated by the objectives of increasing oil exports, raising government revenue and promoting rural development through the sugarcane sector and have had a significant adverse effect on fuel and sugar consumers, aggregate social welfare and greenhouse gas emissions in Brazil. - Highlights: • Relative to a no-policy baseline, status quo fuel policies in Brazil have increased oil exports and government revenue. • These policies benefited the sugarcane producing sector but had a significant adverse effect on fuel and sugar consumers. • These policies have adversely affected aggregate social welfare and greenhouse gas emissions in Brazil. • The cap on domestic oil price provides a marginal gain to fuel and sugar consumers but lower aggregate social welfare.

The aim of this study was to determine the overweight prevalence (BMI ≥ 25kg/m2 and possible associations with socioeconomic and demographic indicators for adults in Brazil. This epidemiological study analyzed data from the population of adults aged 20-59 years (n = 101 308 637 included in the 2008-2009 Brazilian Family Budget Survey (POF conducted in all geographic regions of Brazil. The nutritional status assessment used the Body Mass Index, which was categorized as normal weight and overweight according to cutoff points recommended by the World Health Organization. As socioeconomic and demographic indicators, sex, age, color-race, education, income, and geographic region were analyzed. Crude and adjusted Poisson regression was performed. The results showed that the overweight prevalence was 47.7%, and the groups with the highest prevalence were adults aged 20-59 years, males, black skin color, schooling from 6 to 9 years , income of 1/4 ≥ minimum wage <1/2 and living in Southern Brazil. Almost half of adults in Brazil are overweight. Strategic actions aimed at reducing the overweight prevalence among adults in Brazil are needed to combat the obesity epidemic.

Brazil's primary energy matrix is based on more than 47% of renewables, and more than 85% of its electricity is generated by hydro power sources. Despite this large fraction of renewable energy resources, less than 0.3% of the national energy supply comes from solar or wind sources. This paper presents a diagnostic review on the penetration of the solar and wind energy technologies in Brazil. It also includes a survey of the latest government policies and incentives for renewable energies deployment by entrepreneurs, industry and commercial and residential consumers.

Brazil's primary energy matrix is based on more than 47% of renewables, and more than 85% of its electricity is generated by hydro power sources. Despite this large fraction of renewable energy resources, less than 0.3% of the national energy supply comes from solar or wind sources. This paper presents a diagnostic review on the penetration of the solar and wind energy technologies in Brazil. It also includes a survey of the latest government policies and incentives for renewable energies deployment by entrepreneurs, industry and commercial and residential consumers. In addition, the paper analyses how to best meet the requirements for policy support and information technology to boost the deployment of solar technology and wind energy in Brazil. This study was mostly based on results of a widely distributed survey covering key issues, and also by personal interviews carried out with key stakeholders in order to better understand the issues highlighted in the survey responses. The study pointed out some of the main obstacles to effectively promote and improve government policies and actions for investment in solar and wind energy market in Brazil. - Highlights: → Current status on the solar and wind energy deployment in Brazil is presented. → Policy framework required to support solar and wind energy was discussed. → Study was based on responses for consultations with key stakeholders. → Worthiness Index was established to rank the stakeholders outlooks. → Energy price, human resources and tax reductions were indicated as priority.

The African swine fever episode in Brazil was due to trade and tourism between Spain, Portugal and Brazil, at a time when outbreaks were on the rise in Europe. The eradication of the disease, the slaughter of pigs, the elimination of the carcasses and the isolation of affected farms were given wide media coverage, and had a major socio-economic impact. It was forbidden to raise pigs in garbage dumps or to give them feed considered hazardous. Analyses performed in Brazil as well as national and international investigations by researchers from reference laboratories concluded that the disease had spread from Rio de Janeiro to other states, as is stated in official reports. Following emergency measures, a control programme was implemented, leading to enhanced quality in the pig farming sector. The authors describe epidemiological surveillance of African swine fever, classical swine fever and related diseases, biosafety in swine farming, and the emergency action plan comprising animal health training for veterinarians and social workers. The results of the eradication programme were excellent, despite the controversy over compulsory sacrifice in a country with serious social problems. In 2004, Brazil was the fourth largest pork producer and exporter, with an output of 2.679 million tons and exports of 508,000 tons to international markets with very high standards.

The availability and reliability of wind power depend a great deal on current and future climate conditions, which may vary in light of possible global climate change (GCC). Long-term energy planning, however, does not normally take possible future GCC into consideration, which may turn out to be a risky exercise. In the case of Brazil, the untapped wind power potential is known to be impressive, provided that climate conditions remain the same over time. The focus of this study is to analyze some possible impacts of GCC on the wind power potential of Brazil, by simulating wind conditions associated with the IPCC A2 and B2 Scenarios. Results based on the HadCM3 general circulation model and the analysis of the country's wind database indicate that the wind power potential in Brazil would not be jeopardized in the future due to possible new climate conditions. On the contrary, improved wind conditions are expected, particularly in the Northeast coast of the country. Therefore, investments in wind power generation can be an interesting way to expand renewable energy production in Brazil. However, given the large uncertainties associated with GCC models and scenarios, the findings of this paper should be viewed as a possibility rather than as a projection. (author)

This paper discusses the social, political and cultural status of women in Brazil. In 1976 only 29.6% of Brazilian women participated in economic activities; 54.3% of these were still employed as laborers in the countryside, while only 6% were employed in urban and industrial jobs. The greatest concentration of female labor is in the category of the very badly paid domestic employment. Man is traditionally the head of the family, even when he is not the breadwinner. Illiteracy has decreased in Brazil to 24.3%, but female analphabetism is 26.5% versus 21.9% male analphabetism. Schools are open to males and females at all levels, but the traditional and cultural structure of Brazilian society considers the home, not the school, as the only proper place for young girls, and maternity is still the primary social function of women. Politically Brazilian women have very little power, even if they make up 44% of the electoral body. Sex education does not exist in the school or in the home, and any sexuality exercised outside the bonds of marriage is considered as deviant.

Rapidly developing market regions : Brazil

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

The present study reports field data of ticks infesting wild carnivores captured from July 1998 to September 2004 in Brazil. Additional data were obtained from one tick collection and from previous published data of ticks on carnivores in Brazil. During field work, a total of 3437 ticks were collected from 89 Cerdocyon thous (crab-eating fox), 58 Chrysocyon brachyurus (maned wolf), 30 Puma concolor (puma), 26 Panthera onca (jaguar), 12 Procyon cancrivorus (crab-eating raccoon), 4 Speothos venaticus (bush dog), 6 Pseudalopex vetulus (hoary fox), 6 Nasua nasua (coati), 6 Leopardus pardalis (ocelot), 2 Leopardus tigrinus (oncilla), 1 Leopardus wiedii (margay), 1 Herpailurus yagouaroundi (jaguarundi), 1 Oncifelis colocolo (pampas cat), 1 Eira barbara (tayara), 1 Galictis vittata (grison), 1 Lontra longicaudis (neotropical otter), and 1 Potus flavus (kinkajou). Data obtained from the Acari Collection IBSP included a total of 381 tick specimens collected on 13 C. thous, 8 C. brachyurus, 3 P. concolor, 10 P. onca, 3 P. cancrivorus, 4 N. nasua, 1 L. pardalis, 1 L. wiedii, 4 H. yagouaroundi, 1 Galictis cuja (lesser grison), and 1 L. longicaudis. The only tick-infested carnivore species previously reported in Brazil, for which we do not present any field data are Pseudalopex gymnocercus (pampas fox), Conepatus chinga (Molina's hog-nosed skunk), and Conepatus semistriatus (striped hog-nosed skunk). We report the first tick records in Brazil on two Felidae species (O. colocolo, H. yagouaroundi), two Canidae species (P. vetulus, S. venaticus), one Procyonidae species (P. flavus) and one Mustelidae (E. barbara). Tick infestation remains unreported for 5 of the 26 Carnivora species native in Brazil: Oncifelis geoffroyi (Geoffroy's cat), Atelocynus microtis (short-eared dog), Pteronura brasiliensis (giant otter), Mustela africana (Amazon weasel), and Bassaricyon gabbii (olingo). Our field data comprise 16 tick species represented by the genera Amblyomma (12 species), Ixodes (1

Genetics against race: Science, politics and affirmative action in Brazil.

This article analyses interrelations between genetic ancestry research, political conflict and social identity. It focuses on the debate on race-based affirmative action policies, which have been implemented in Brazil since the turn of the century. Genetic evidence of high levels of admixture in the Brazilian population has become a key element of arguments that question the validity of the category of race for the development of public policies. In response, members of Brazil's black movement have dismissed the relevance of genetics by arguing, first, that in Brazil race functions as a social--rather than a biological--category, and, second, that racial classification and discrimination in this country are based on appearance, rather than on genotype. This article highlights the importance of power relations and political interests in shaping public engagements with genetic research and their social consequences.

Global governance is of key concern in the current debate over the workings of the world's computer network, and Brazil has played a notable role in this process, especially after approval of the Marco Civil da Internet (law 12.965, april 23, 2014), which defines Brazil's regulatory framework for the internet. Dubbed the internet bill of rights, this law sets out the principles, guarantees, rights, and duties of internet users and providers in Brazil. Based on the fundamental categories of net neutrality, internet users' right to privacy, and copyright discussions from the perspective of intellectual property, the article offers a comparative analysis of regulations in five countries: Brazil, Chile, Spain, the US, and France.

Recent restructuring of Brazil's power sector, allied to the expected larger share of natural gas in the nation's grid and the cost reductions of gas-fired power generation technologies, has introduced a set of situations apparently favorable to the expansion of natural gas-fired cogeneration. However, electricity self-generation applications are restricted to specific cases in Brazil. In order to deal with this issue, the COGEN model was developed to assess the economic potential of cogeneration ventures from the standpoint of the investor and guide incentive public policies. This model has been applied to two cases in Brazil -- a chemical plant and a shopping mall -- showing that the highest economic potential for gas-fired cogeneration in Brazil is found in industrial plants faced with high values of loss of load. In the commercial sector, measures reshaping the load curve of enterprises -- such as cold storage --- might be much more interesting than fired cogeneration. (Author)

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