    Full Text Available Exclusive breastfeeding is acknowledged as important for survival, optimal growth, and development of infants. The current review presents a synthesis of research output by Brazilian nurses on breastfeeding over the last 20 years, analyzes the theoretical and methodological issues emerging from studies on breastfeeding in Brazil, and provides directions for future research and practice by nurses in the area breastfeeding. Studies included in this review were identified through LILACS searches of Portuguese-language sources. Articles were organized and analyzed chronologically by comparing the evolution of the Brazilian Breastfeeding Program. The incomplete research output of the Brazilian nursing profession in regard to breastfeeding research needs to be addressed. In addition, specific cultural, sociological, and anthropological characteristics of Brazilian regional settings remain to be explored. Emphasis on potential confounders and critical interrelations is warranted.

    Full Text Available This study aims to analyze the trend of indicators related to smoking in the capitals of Brazil from 2006 to 2013. Information on smoking trends extracted from the survey of risk and protective factors for chronic non-communicable diseases (NCDs are analyzed through telephone interviews - VIGITEL conducted from 2006-2013 for the adult population in Brazilian capitals. To estimate the trend, the simple linear regression model was used. The prevalence of smokers in Brazil showed a relative reduction of 0.62% for each year of the survey, ranging from 15.6% in 2006 to 11.3% in 2013. A decrease was observed in both sexes in all age ranges except between 55 and 64 years in all education levels and regions. The total population of former smokers remained stable, with a reduction for men. Smoking 20 or more cigarettes per day decreased from 4.6% (2006 to 3.4% (2013, or 0.162 percentage points per year. Passive smoking at home decreased among women 13.4% (2009 to 10.7% (2013, a reduction of 0.72% per annum. Passive smoking at work has remained stable over the period. The smoking trend reduced in the period in most indicators, reflecting the importance of the tobacco control actions in the country.

    Full Text Available The first part of this paper describes Brazilian general book market quantitative data on the period from 2000 to 2009; the second part analyzes the list of best sellers in Brazil on that period, focusing on the presence of Brazilian fiction writers on it. Our analysis points to the conclusion that there is an undeniable quantitative increase on such market but it is not accompanied by innovation. Most titles are world wide best sellers from Anglo-Saxon culture that receive massive publishing campaign and issuing, and represent very little risk to the publishing industry. As for Brazilian writers, they were already well known, especially from TV.

    Full Text Available Objective: To evaluate trends in psychiatric bed occupancy by elderly inpatients in the Brazilian public health care system between 2000 and 2010 and to determine the leading psychiatric diagnosis for hospital admissions. Methods: Data from all 895,476 elderly psychiatric admissions recorded in the Brazilian Public Health Care Database (DATASUS between January 2000 and February 2010 were analyzed. Polynomial regression models with estimated curve models were used to determine the trends. The number of inpatient days was calculated for the overall psychiatric admissions and according to specific diagnoses. Results: A moderate decreasing trend (p < 0.001 in the number of inpatient days was observed in all geriatric psychiatric admissions (R2 = 0.768 and in admissions for organic mental disorders (R2 = 0.823, disorders due to psychoactive substance use (R2 = 0.767, schizophrenia (R2 = 0.680, and other diagnoses (R2 = 0.770, but not for mood disorders (R2 = 0.472. Most admissions (60 to 65% were due to schizophrenia. Conclusion: There was a decreasing trend in inpatient days for elderly psychiatric patients between 2000 and 2010. The highest bed occupancy was due to schizophrenia, schizotypal, and delusional disorders.

    OBJECTIVE To analyze temporal trends of the prevalence of alcohol and tobacco use among Brazilian students. METHODS We analyzed data published between 1989 and 2010 from five epidemiological surveys on students from the 6th to the 12th grade of public schools from the ten largest state capitals of Brazil. The total sample consisted of 104,104 students and data were collected in classrooms. The same collection tool – a World Health Organization self-reporting questionnaire – and sampling and weighting procedures were used in the five surveys. The Chi-square test for trend was used to compare the prevalence from different years. RESULTS The prevalence of alcohol and tobacco use varied among the years and cities studied. Alcohol consumption decreased in the 10 state capitals (p < 0.001) throughout 21 years. Tobacco use also decreased significantly in eight cities (p < 0.001). The highest prevalence of alcohol use was found in the Southeast region in 1993 (72.8%, in Belo Horizonte) and the lowest one in Belem (30.6%) in 2010. The highest past-year prevalence of tobacco use was found in the South region in 1997 (28.0%, in Curitiba) and the lowest one in the Southeast in 2010 (7.8%, in Sao Paulo). CONCLUSIONS The decreasing trend in the prevalence of tobacco and alcohol use among students detected all over the Country can be related to the successful and comprehensive Brazilian antitobacco and antialcohol policies. Despite these results, the past-year prevalence of alcohol consumption in the past year remained high in all Brazilian regions. PMID:26465662

    Full Text Available OBJECTIVE - To analyze the trends in risk of death due to cardiovascular diseases in the northern, northeastern, southern, southeastern, and central western Brazilian geographic regions from 1979 to 1996. METHODS - Data on mortality due to cardiovascular, cardiac ischemic, and cerebrovascular diseases in 5 Brazilian geographic regions were obtained from the Ministry of Health. Population estimates for the time period from 1978 to 1996 in the 5 Brazilian geographic regions were calculated by interpolation with the Lagrange method, based on the census data from 1970, 1980, 1991, and the population count of 1996, for each age bracket and sex. Trends were analyzed with the multiple linear regression model. RESULTS - Cardiovascular diseases showed a declining trend in the southern, southeastern, and northern Brazilian geographic regions in all age brackets and for both sexes. In the northeastern and central western regions, an increasing trend in the risk of death due to cardiovascular diseases occurred, except for the age bracket from 30 to 39 years, which showed a slight reduction. This resulted from the trends of cardiac ischemic and cerebrovascular diseases. The analysis of the trend in the northeastern and northern regions was impaired by the great proportion of poorly defined causes of death. CONCLUSION - The risk of death due to cardiovascular, cerebrovascular, and cardiac ischemic diseases decreased in the southern and southeastern regions, which are the most developed regions in the country, and increased in the least developed regions, mainly in the central western region.

    In Brazil, where cultivated pastures constitute the dominant land use form, cattle ranching intensification plays a major role towards more environmentally sustainable agricultural practices, through its potential for mitigating GHG emissions, as well as by making available cost-effective land reserve for other uses. However, environmentally sustainable livestock intensification, one of the key goals pursued by Plano ABC (the federal government low carbon agriculture plan), strongly depends on our ability to more precisely identify pasture conditions, improvement needs, and the respective cattle support capacities. To this end, and with the support of the Gordon and Betty Moore Foundation, we have concentrated efforts in order to have: 1) a more detailed and updated map of the brazilian pasturelands; 2) a thorough biophysical differentiation of these pastures according to degradation stages / forage levels; and 3) an estimation of overall pasture productivity trends. Our initial estimates, based on the interpretation of satellite and census data, suggest that as much as 50% of the total grazing area in Brazil (about 170 Mhectares) are moderately or severely affected by soil-plant degradation. On the other hand, our preliminary results also corroborate the enormous potential of well managed pastures to positively impact carbon and water fluxes. Based on satellite data and pasture samples from large and productive cattle ranch operations in the central savanna biome in Brazil (Cerrado), we estimated total growing season (October to April) biomass and evapotranspiration to correspond to 9 Gt of carbon and 420 Gt of water, respectively.

    Full Text Available This study presents data from a survey on height trends in Brazilian Navy enlisted men and recruits born from 1970 to 1977. The sample consisted of 52,574 enlisted men and 4,459 recruits ranging in age from 18.00 to 18.99 years. The statistical processing employed two-way analysis of variance procedure, simple linear regression comparing height and year of birth and multiple analysis controlling for schooling (regression coefficient and the chi-square. The results show that enlisted men and recruits displayed height increments, characterizing a contemporary process of secular trend. Such increments were also present in the country's various macro-regions. The results were compared to a recent investigation of a national scope the National Survey on Health and Nutrition (PNSN and both enlisted men and recruits displayed higher median height than that reported by the PNSN. Level of schooling for individuals in the Navy is high, far superior to that of the Brazilian population as a whole. This set of data suggests that young men enlisting in the Navy are on average of a higher socioeconomic status than the Brazilian population in general, which limits possibilities for extrapolating the findings from this research.

    Full Text Available OBJECTIVE To analyze conditional and unconditional healthy life expectancy among older Brazilian women. METHODS This cross-sectional study used the intercensal technique to estimate, in the absence of longitudinal data, healthy life expectancy that is conditional and unconditional on the individual’s current health status. The data used were obtained from the Pesquisa Nacional por Amostra de Domicílios (National Household Sample Survey of 1998, 2003, and 2008. This sample comprised 11,171; 13,694; and 16,259 women aged 65 years or more, respectively. Complete mortality tables from the Brazilian Institute of Geography and Statistics for the years 2001 and 2006 were also used. The definition of health status was based on the difficulty in performing activities of daily living. RESULTS The remaining lifetime was strongly dependent on the current health status of the older women. Between 1998 and 2003, the amount of time lived with disability for healthy women at age 65 was 9.8%. This percentage increased to 66.2% when the women already presented some disability at age 65. Temporal analysis showed that the active life expectancy of the women at age 65 increased between 1998-2003 (19.3 years and 2003-2008 (19.4 years. However, life years gained have been mainly focused on the unhealthy state. CONCLUSIONS Analysis of conditional and unconditional life expectancy indicated that live years gained are a result of the decline of mortality in unhealthy states. This pattern suggests that there has been no reduction in morbidity among older women in Brazil between 1998 and 2008.

    Full Text Available INTRODUCTION: In the past two decades members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. This study prospectively analyzed the distribution of species and trends in antimicrobial resistance among clinical isolates of enterococci in a Brazilian tertiary hospital from 2006-2009. METHODS: Enterococcal species were identified by conventional biochemical tests. The antimicrobial susceptibility profile was performed by disk diffusion in accordance with the Clinical and Laboratory Standards Institute (CLSI. A screening test for vancomycin was also performed. Minimal inhibitory concentration (MIC for vancomycin was determined using the broth dilution method. Molecular assays were used to confirm speciation and genotype of vancomycin-resistant enterococci (VRE. RESULTS: A total of 324 non-repetitive enterococcal isolates were recovered, of which 87% were E. faecalis and 10.8% E. faecium. The incidence of E. faecium per 1,000 admissions increased significantly (p 256µg/ mL and harbored vanA genes. The majority (89.5% of VRE belonged to E. faecium species, which were characteristically resistant to ampicillin and quinolones. Overall, ampicillin resistance rate increased significantly from 2.5% to 21.4% from 2006-2009. Resistance rates for gentamicin, chloramphenicol, tetracycline, and erythromycin significantly decreased over time, although they remained high. Quinolones resistance rates were high and did not change significantly over time. CONCLUSIONS: The data obtained show a significant increasing trend in the incidence of E. faecium resistant to ampicillin and vancomycin.

    for hot and high rainfall summer season. Brazilian preference for the Grand Rapids type is a unique event in the world market of lettuce. Crisp head lettuce had increased its preference, but there are many limitations to grow this type outdoors in our rainy hot summer. Thicker leaves of iceberg have a better flavor, crispness and long shelf live under refrigeration for its post-harvest management. Crispness is an important and mandatory quality for the fresh cut market which is a growing tendency. Considerations on breeding focus to get tropical-adapted varieties with crispness and resistance to specific Brazilian diseases which are limiting to lettuce are discussed.

    Full Text Available The investigation of bathymetric distribution of five snappers caught along the Brazilian Northeastern coast by artisanal fleets through the analysis of the catch composition and relative abundance (CPUE showed that, on the overall, fished mean size increased along depth and that particular species dominated the catch according to the depth strata. Mutton snapper, L. analis, yellowtail snapper, L. chrysurus, and dog snapper, L. jocu were mainly caught at intermediate depth (20-80m whereas lane snapper, L. synagris, and silk snapper, L. vivanus, inhabit respectively shallow (80 m waters. Each fleet category exploited preferentially a particular combination of species and their size range. The fleet dynamic of the Northeast Brazil is technologically heterogeneous and determines the catch composition. Geographical distribution of the fishery and technical interaction between fleets and gears should be considered by the management of these species in order to maintain the sustainability of the stock and to guarantee the continuance of the resource.A distribuição batimétrica de cinco espécies de peixes do Nordeste Brasileiro foi examinada através da análise da composição da captura e e abundância relativa (CPUE mostrou que, de uma maneira geral, o comprimento furcal aumentou com a profundidade e que algumas espécies dominaram a captura de acordo com a faixa de profundidade.

    Estuaries are threatened coastal ecosystems that support relevant ecological functions worldwide. The predicted global climate changes demand actions to understand, anticipate and avoid further damage to estuarine habitats. In this study we reviewed data on polychaete assemblages, as a surrogate for overall benthic communities, from 51 estuaries along five Marine Ecoregions of Brazil (Amazonia, NE Brazil, E Brazil, SE Brazil and Rio Grande). We critically evaluated the adaptive capacity and ultimately the resilience to decadal changes in temperature and rainfall of the polychaete assemblages. As a support for theoretical predictions on changes linked to global warming we compared the variability of benthic assemblages across the ecoregions with a 40-year time series of temperature and rainfall data. We found a significant upward trend in temperature during the last four decades at all marine ecoregions of Brazil, while rainfall increase was restricted to the SE Brazil ecoregion. Benthic assemblages and climate trends varied significantly among and within ecoregions. The high variability in climate patterns in estuaries within the same ecoregion may lead to correspondingly high levels of noise on the expected responses of benthic fauna. Nonetheless, we expect changes in community structure and productivity of benthic species at marine ecoregions under increasing influence of higher temperatures, extreme events and pollution.

    Full Text Available OBJECTIVE: To describe the annual evolution of the prevalence of overweight and obesity in the adult population of the 26 Brazilian state capitals and the Federal District from 2006 to 2012. METHODS: Annual interviews (around 54,000 per year from VIGITEL (Surveillance System of Risk and Protective Factors for Chronic Non-Communicable Diseases through Telephone Interviews were used. Self-reported weight and height were used to estimate body mass index and nutritional status. Prevalence estimates of overweight and obesity are presented according to gender, age and schooling and to each city. Linear regression model was used to evaluate the time trend of prevalence. RESULTS: Prevalence of overweight in adults in the 27 cities monitored by VIGITEL increased from 43.2% (2006 to 51.0% (2012, with an annual increase rate of 1.37%. Prevalence of obesity increased from 11.6% to 17.4%, with an annual increase rate of 0.89%. The study showed a statistically significant increase in the prevalence of overweight in all cities, and for both genders, all age groups and all levels of schooling. Similar trends were also verified for obesity. CONCLUSIONS: If the trends verified from 2006 to 2012 are maintained, in ten years, around two-thirds of the adults in Brazilian state capitals will be overweight, and a quarter will be obese. This perspective requests urgent response from government and intersectoral actions to combat the obesogenic environment.

    In recent years a trend on increasing requirements for local investments has been observed worldwide in the petroleum industry. Host countries expect to have increasing social and economical benefits from the development of the oil and gas industry. This expectation drives at a more comprehensive concept of local content to include commitment with social, industrial, and technological development. The Brazilian experience has shown a lot of emphasis on local industry development. Initiatives from governmental authorities and the private sector have been implemented to increase the local industry participation in the oil and gas projects. The current regulation focus on the full and fair opportunities for the local suppliers and the local content commitment established in the E and P concession agreements. A key issue on promoting local content initiatives is to assure that the competitiveness of the indigenous industry will be developed and preserved. The constraints on building up the local industry competitiveness will be addressed, focusing on the taxation overburden, lack of adequate local financing, and internal structural aspects affecting industrial productivity. In addition to this, the experiences on measuring local content for offshore construction and drilling are highlighted. Technology development and technical capability have been addressed by incentive programs for the O and G sector. Finally, the technology learning process and the regulatory requirements to invest in R and D programs conducted by Brazilian technological institutions are discussed. (author)

    Wind speed trends have been extensively researched for the Northern Hemisphere and Australia. The general consensus among scientists is that wind speeds have declined over the past century. However, a minimal amount of research has focused on understanding how wind speeds changed across Brazil based on temporal and geographical perspectives. Therefore, this study provides a climatological assessment of wind speed trends across Brazil using in-situ and climatic model datasets from 1980-2014. Seasonal and annual trends are determined across the study area using linear and quantile regression. Geographical Information Systems is used to interpret and understand how wind speed trends have changed across Brazil. Preliminary results show two distinct wind speed trend patterns exist across Brazil. The largest wind speed magnitude increases occurred along northeastern and coastal Brazil, where as decreasing wind speeds have been observed for central and southeastern Brazil. Furthermore, quantile regression also shows the largest seasonal and annual wind trend fluctuations occur at lower (5%) and upper percentiles (95%) for both in-situ and climate model datasets. As a result, these findings indicate possible alterations in atmospheric and oceanic circulations could be affecting wind speed trends across Brazil and warrants further investigation and research.

    Full Text Available Objective: To compare intimate partner violence (IPV prevalence rates in 2006 and 2012 in a nationally representative household sample in Brazil. The associations between IPV and substance use were also investigated. Methods: IPV was assessed using the Conflict Tactic Scale-R in two waves (2006/2012 of the Brazilian Alcohol and Drugs Survey. Weighted prevalence rates and adjusted logistic regression models were calculated. Results: Prevalence rates of IPV victimization decreased significantly, especially among women (8.8 to 6.3%. The rates of IPV perpetration also decreased significantly (10.6 to 8.4% for the overall sample and 9.2 to 6.1% in men, as well as the rates of bidirectional violence (by individuals who were simultaneously victims and perpetrators of violence (3.2 to 2.4% for the overall sample. Alcohol increased the likelihood of being a victim (odds ratio [OR] = 1.6 and perpetrator (OR = 2.4 of IPV. Use of illicit drugs increased up to 4.5 times the likelihood of being a perpetrator. Conclusions: In spite of the significant reduction in most types of IPV between 2006 and 2012, violence perpetrated by women was not significantly reduced, and the current national rates are still high. Further, this study suggests that use of alcohol and other psychoactive drugs plays a major role in IPV. Prevention initiatives must take drug misuse into consideration.

    During my first employment as a junior biologist conducting food habits analyses at the Patuxent Research Refuge (now Patuxent Wildlife Research Center) of the US Fish and Wildlife Service, the first station director, Arnold L. Nelson, gave each staff biologist the opportunity to spend a little time conducting field studies on the 2,600-acre research area. These studies were to help in ecological evaluation of the area, but also, no doubt, functioned as a morale builder for biologists daily engaged in difficult, demanding and confining laboratory work. I undertook to measure the population density of small mammals in different habitats. The state-of-the-art methods recommended to me and prevalent in the literature worried me, especially after preliminary field work. Reading the classic, paper by W.H. Burt [Terrioriality and home range concepts as applied to mammals. J. Mammalogy 24:346-352, 1943] was a turning point for me in seeing that knowledge of home-range size was the key to measuring population density. My first papers employed these concepts in field evaluations. However, they could give-only limited attention to the question of how home ranges could be measured. Furthermore, the importance of knowledge of the home range to habitat evaluation and to understanding animal behavior was becoming increasingly apparent. Advocacy of many different methods of measuring home ranges appeared in the literature. It did not seem possible to evaluate them objectively. It occurred to me that artificial populations could be used to help in understanding the mechanisms of measuring home ranges. The effects of random trap-visiting, bias toward central traps, trap-spacing, range shape, and other factors could be considered. So grids of traps were inked onto oversize graph paper, and simulated ranges were cut from plastic to be tossed as randomly as possible on the trap-grids. It was a slow, laborious job. Analysis showed that random captures in artificial populations produced

    Full Text Available In this article, the expansion of distance learning (DL in Brazil’s Higher Education is analyzed with a view to addressing the following research query: How many schools, in Brazil, will offer undergraduate studies in the DL mode over the next five years?To this effect, bibliographical data was researched and historical series of variables were compiled – number of schools, of courses and of enrolled students, among other elements – to generate comparative graphs between the in loco (classroom and the distance modes. Thus, the evolution of both types during the period studied is presented.Furthermore, a simple linear regression was used to correlate the variables ‘number of institutions’ and ‘time’, in order to extrapolate growth trends for the 2007-2011 period. Results point to a sharp expansion of DL, in all studied variables, and indicate that this may increase even further in the future.It also became evident that the growth of distance learning will have to overcome certain challenges, including better access to computers and to the Internet and the development of qualified personnel and of specific software to deal with it.Key words: Distance learning. Distance education. Extrapolation of trends and linear regression. Future studies.

A amostra final constituiu-se de 3.269 indivíduos com idade entre 18,00-18,99 anos. Foram realizadas as análises estatísticas: Anova (one-way e two-way, teste de Sheffe, regressão simples entre estatura e ano de nascimento e múltipla, controlando para escolaridade (coeficiente angular, e Qui-Quadrado. Os resultados demonstraram existência de um aumento progressivo em estatura da ordem de 0,1 cm/ano para o conjunto das regiões do País. Também se verificou tendência positiva em quase todas regiões e estratos de escolaridade. Em nível nacional, este aumento pode ser atribuído a melhorias em alguns indicadores sanitários. Argumenta-se que os resultados não podem ser diretamente extrapolados para a população brasileira como um todo, uma vez que os jovens que se alistam na Marinha apresentam um perfil antropométrico e sócio-econômico diferenciado daquele da população geral.The present paper reports data on secular trends in the stature of Brazilian Navy recruits born from 1940 to 1965. The final sample included 3269 individuals aged 18.00-18.99. Statistics performed were: Anova (one-way and two-way, Sheffe test, simple linear regression between stature and year of birth, and multiple linear regression adjusting for level of schooling (beta coefficient and chi-square. Results indicated a progressive growth trend in stature of 0.1 cm/yr. for the country as a whole. The trend was also observed for nearly all regions and two out of three levels of schooling and can be explained by improvement in some of the country's health indicators. One important characteristic was a higher level of schooling observed among Navy recruits, suggesting that these individuals represent a highly select group, and that therefore data on the Navy cannot be applied directly to the Brazilian population as a whole.

    2011-02-01

    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

MÉTODOS: Estudo ecológico exploratório de séries temporais com utilização de dados secundários. Foram calculadas as taxas de afastamento segundo secretaria, sexo e grupos de patologias. Utilizou-se o procedimento de Prais-Winsten para a análise de tendência. RESULTADOS: Foram analisados 40.370 afastamentos. A tendência das taxas de afastamento foi de decréscimo para ambas as secretarias, considerando ambos os gêneros. Para o gênero feminino da SEA, a tendência foi de estabilidade. As taxas foram mais elevadas na SES. O número médio de dias de afastamento aumentou no decorrer do período analisado. Segundo os grupos de patologias (CID 10, as maiores taxas foram encontradas nos capítulos V, XIII, XXI, XIX e IX. CONCLUSÕES: A tendência de decréscimo das taxas de afastamento e o respectivo aumento da média de dias de afastamento refletem mudanças no perfil de morbidade dos servidores públicos, com o predomínio de transtornos mentais e doenças do sistema osteomuscular, que exigem maior tempo de recuperação para o retorno ao trabalho. O estudo sugere a investigação de fatores associados ao adoecimento que fundamentem as políticas de saúde do servidor.OBJECTIVE: To analyze time trends of sick leave rates among state civil servants in the State Secretariats of Health and of Administration in Santa Catarina, Brazil from 1995 to 2005.

    Collections of mammals were made during more than three years of biological investigations in Chile sponsored by the Corporación Nacional Forestal under the aegis of the Peace Corps (Smithsonian Environmental Program). Genera and species hitherto unreported for that country were taken and many useful data concerning distributional patterns of other (mostly little-known) species were gathered. These collections have also proved valuable in better understanding Chilean mammals from a taxonomic point of view and contribute knowledge of the species' natural history. Specimens are to be deposited in the (United States) National Museum of Natural History (USNM) or are to be retained by the Corporación Nacional Forestal, Avda, Bulnes 285, Depto. 401, Santiago. Numbers provided below are field numbers. A final division of specimens between the two institutions has not yet been made. A number of specimens reported here were not taken by Peace Corps personnel but have been obtained by the National Museum of Natural History from other sources. Specimens in the Field Museum of Natural History (FMNH) were used in making comparisons. Some of Fulk's (GWF) specimens are at Texas Tech University. Other are at the Servicio Agricola y Ganadero in Santiago (as are specimens of some introduced species taken by Schamberger).

    of state capitals comprises about a quarter of the total Brazilian population and for these cities mortality data available have a better quality than for the entire country, enabling analyses of trends in cancer rates based on more accurate data. METHODS: Mortality and population data were collected from government databases (SIM/DATASUS and IBGE, respectively. Age-adjusted (world standard and age-specific mortality rates were calculated for both genders . Linear regression was used to investigate changes in trends. RESULTS: For all cancers as a whole mortality rates declined throughout the study period for both men and women (-4.6% and -10.5%, respectively. For both genders , the cancer that decreased most was stomach cancer. Among men, lung cancer death rates presented a slight reduction, while prostate cancer rates increased. Among women, "uterus, site unspecified' presented a downward trend, while lung cancer rates increased. The trend for breast cancer remained stable, and cervix uterus rates showed a slight increase at the end of the period. CONCLUSION: As already seen in developed countries, all cancer mortality rates tended to decline in Brazilian state capitals over the period 1980-2004, a tendency largely due to a decline in stomach cancer death rates for both genders.

    The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D) is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy) and regular physical activity (structured exercise) represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA) is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation.

Não foi diferente no Brasil, tal atenção pode ser comprovada pelos inúmeros trabalhos científicos sobre nanocompósitos que começaram a despontar no início do século XXI. Assim, o presente artigo objetiva, após discorrer sobre as definições que concernem nanocompósitos polímero/argila, apresentar as pesquisas científicas brasileiras em nanocompósitos de polímeros de uso geral, de polímeros de engenharia e de outros tipos de polímeros, relacionando-os com o método de produção empregado, morfologia final e propriedades decorrentes da formação de nanocompósitos. Por fim, o mapa da pesquisa brasileira em nanocompósitos polímero/argila e sua perspectiva para o futuro são apresentados.The research on polymer/clay nanocomposites was initiated by Toyota in the late 80s. From then on, the world scientific community has turned its attention to this type of material due to the enhanced mechanical, chemical and thermal properties in comparison to traditional composites. In Brazil, it was not different, as can be seen from the countless scientific works on nanocomposites which have emerged in the early 21th century. The aim thus is, after discussing the definitions related to the polymer/ clay nanocomposites, to show Brazilian scientific works on the general use of plastics, engineering plastics and other types of polymers, correlating them with their production method, final morphology and resulting properties. Finally, a map of the Brazilian research into polymer/clay nanocomposites and their future perspective are presented.

    Full Text Available Brazil was the first developing country to provide free, universal access to antiretroviral treatment for AIDS patients. The Brazilian experience thus provides the first evidence regarding the impact of such treatment on the survival of perinatally acquired AIDS cases in the developing world. MATERIAL AND METHODS: This retrospective cohort study used medical record reviews to examine characteristics and trends in the survival of a representative sample of 914 perinatally acquired AIDS cases in 10 Brazilian cities diagnosed between 1983 and 1998. RESULTS: Survival time increased steadily and substantially. Whereas half of the children died within 20 months of diagnosis at the beginning of the epidemic, 75% of children diagnosed in 1997 and 1998 were still alive after four years of follow-up. CONCLUSIONS: Advances in management and treatment have made a great difference in the survival of Brazilian children with AIDS. These results argue strongly for making such treatment available to children in the entire developing world.

This was a bibliographical study using a quantitative approach, performed from June 15 to July 31, 2009. To collect empirical data, we used a structured instrument, then the data were tabulated, analyzed, transformed into percentages and grouped into a table for easy viewing of the information. The sample consisted of abstracts obtained through an electronic search, using the BIREME, LILACS, SciELO, MEDLINE and BDENF databases. One hundred and eleven articles were found and after applying the inclusion criteria, there was a final sample of 69 articles. Trends identified in the majority of abstracts were for qualitative research, the main focus being on rehabilitation. The region that has carried out most investigations was the Southeast, followed by the Northeast. Many articles had no essential methodological information to allow the reader to understand the data, making it difficult to conduct searches in these databases.

    Springer et al. (2003) contend that sequential declines occurred in North Pacific populations of harbor and fur seals, Steller sea lions, and sea otters. They hypothesize that these were due to increased predation by killer whales, when industrial whaling's removal of large whales as a supposed primary food source precipitated a prey switch. Using a regional approach, we reexamined whale catch data, killer whale predation observations, and the current biomass and trends of potential prey, and found little support for the prey-switching hypothesis. Large whale biomass in the Bering Sea did not decline as much as suggested by Springer et al., and much of the reduction occurred 50-100 yr ago, well before the declines of pinnipeds and sea otters began; thus, the need to switch prey starting in the 1970s is doubtful. With the sole exception that the sea otter decline followed the decline of pinnipeds, the reported declines were not in fact sequential. Given this, it is unlikely that a sequential megafaunal collapse from whales to sea otters occurred. The spatial and temporal patterns of pinniped and sea otter population trends are more complex than Springer et al. suggest, and are often inconsistent with their hypothesis. Populations remained stable or increased in many areas, despite extensive historical whaling and high killer whale abundance. Furthermore, observed killer whale predation has largely involved pinnipeds and small cetaceans; there is little evidence that large whales were ever a major prey item in high latitudes. Small cetaceans (ignored by Springer et al.) were likely abundant throughout the period. Overall, we suggest that the Springer et al. hypothesis represents a misleading and simplistic view of events and trophic relationships within this complex marine ecosystem. ?? 2007 by the Society for Marine Mammalogy.

    Full Text Available The Bolsa Escola (‘school stipend’ and its successor the Bolsa Familia (‘family stipend’ schemes have formed a crucial and successful part of Brazil’s welfare program. Bolsa Escola provided aid to Brazil’s poorest families on the condition that their children attended school, and Bolsa Familia has extended this idea, giving aid on the condition that children both attend school and receive vaccinations. Bolsa Familia is currently the largest Conditional Cash Transfer Program (CCTP in the world, costing roughly 0.5% of Brazilian GDP and helping around 11.2 million families (around 44 million Brazilians, constituting roughly one fifth of the population. Multilateral institutions have praised the schemes, and they are setting a leading example to other developing nations. In 2005, Paul Wolfowitz (former president of the World Bank said, ‘Bolsa Familia has already become a highly praised model of effective social policy. Countries around the world are drawing lessons from Brazil’s experience and are trying to produce the same results for their own people’.

    By means of scientometric indicators, this study investigated the characteristics of scientific production and research collaboration involving zebrafish (Danio rerio) in Brazilian Science indexed by the Web of Science (WoS). Citation data were collected from the WoS and data regarding Impact Factor (IF) were gathered from journals in the Journal Citation Reports. Collaboration was evaluated according to coauthorship data, creating representative nets with VOSviewer. Zebrafish has attained remarkable importance as an experimental model organism in recent years and an increase in scientific production with zebrafish is observed in Brazil and around the world. The citation impact of the worldwide scientific production is superior when compared to the Brazilian scientific production. However, the citation impact of the Brazilian scientific production is consistently increasing. Brazil does not follow the international trends with regard to publication research fields. The state of Rio Grande do Sul has the greatest number of articles and the institution with the largest number of publications is Pontifícia Universidade Católica do Rio Grande do Sul. Journals' average IF is higher in Brazilian publications with international coauthorship, and around 90% of articles are collaborative. The Brazilian institutions presenting the greatest number of collaborations are Pontifícia Universidade Católica do Rio Grande do Sul, Universidade Federal do Rio Grande do Sul, Fundação Universidade Federal de Rio Grande, and Universidade de São Paulo. These data indicate that Brazilian research using zebrafish presents a growth in terms of number of publications, citation impact, and collaborative work. PMID:27045850

The estimated individual proportions of biogeographical ancestry vary widely and continuously among Brazilians, most individuals - irrespective of self-identification as White, Brown or Black, the major categories of the Brazilian Census race/color system - having significant degrees of European and African ancestry, while a sizeable number display also Amerindian ancestry. These features have important pharmacogenetic (PGx implications: first, extrapolation of PGx data from relatively well-defined ethnic groups is clearly not applicable to the majority of Brazilians; second, the frequency distribution of polymorphisms in pharmacogenes (e.g. CYP3A5, CYP2C9, GSTM1, ABCB1, GSTM3, VKORC, etc varies continuously among Brazilians and is not captured by race/color self-identification; third, the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of PGx studies in order to avoid spurious conclusions based on improper matching of study cohorts.

    Full Text Available The theme of corporate social responsibility (CSR has not been widely examined in the context of multinationals. This dearth is even greater with respect to subsidiaries, particularly the subject of reverse transfer of practices, that is, the transfer of practices developed in subsidiaries back to the parent company. Because of this theoretical gap, the present article investigates the factors involved on reverse transfer of CSR practices. The research hypotheses test the importance of developing nonlocation-bound capabilities, of integration between subsidiaries and parent and of institutional distance. The data were obtained by a survey of the main foreign subsidiaries in Brazil. All told, we analyzed 150 Brazilian subsidiaries of multinationals, by applying multiple linear regression. The results indicate that the reverse transfer of CSR depends on the development of nonlocation-bound capabilities of the subsidiaries and integration between the parent company and its foreign subsidiaries.

    The objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

    Full Text Available INTRODUCTION: In the past two decades members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. This study prospectively analyzed the distribution of species and trends in antimicrobial resistance among clinical isolates of enterococci in a Brazilian tertiary hospital from 2006-2009. METHODS: Enterococcal species were identified by conventional biochemical tests. The antimicrobial susceptibility profile was performed by disk diffusion in accordance with the Clinical and Laboratory Standards Institute (CLSI. A screening test for vancomycin was also performed. Minimal inhibitory concentration (MIC for vancomycin was determined using the broth dilution method. Molecular assays were used to confirm speciation and genotype of vancomycin-resistant enterococci (VRE. RESULTS: A total of 324 non-repetitive enterococcal isolates were recovered, of which 87% were E. faecalis and 10.8% E. faecium. The incidence of E. faecium per 1,000 admissions increased significantly (p 256µg/ mL and harbored vanA genes. The majority (89.5% of VRE belonged to E. faecium species, which were characteristically resistant to ampicillin and quinolones. Overall, ampicillin resistance rate increased significantly from 2.5% to 21.4% from 2006-2009. Resistance rates for gentamicin, chloramphenicol, tetracycline, and erythromycin significantly decreased over time, although they remained high. Quinolones resistance rates were high and did not change significantly over time. CONCLUSIONS: The data obtained show a significant increasing trend in the incidence of E. faecium resistant to ampicillin and vancomycin.INTRODUÇÃO: Nas últimas duas décadas, os enterococos emergiram como importantes patógenos nosocomiais no mundo inteiro.

We draw up a statistical description of Brazilian human capital dispersion in time over the last half century, across regions and states. Our analysis suggests several conclusions: 1 Strong reduction of educational inequalities measured by Education Gini index. 2 A three parts picture of Brazil seems to emerge, reflecting initial conditions. 3 High increase of the Average number of Years of Schooling. 4 A significant link between Education Gini and the average education length. 5 Education Standard Deviation leads to inverted results compared to Education Gini. 6 Brazilian data are consistent with an Education Kuznets curve if we consider Education Standard Deviation.Esse trababalho busca avaliar o grau de desigualdade educacional no Brasil baseado-se em diferentes indicatores tais como: o índice de Gini educacional, os anos médios de escolaridade e no desvio padrão educacional.

    In this work, we study the behavior of Brazilian politicians and political parties with the help of clustering algorithms for signed social networks. For this purpose, we extract and analyze a collection of signed networks representing voting sessions of the lower house of Brazilian National Congress. We process all available voting data for the period between 2011 and 2016, by considering voting similarities between members of the Congress to define weighted signed links. The solutions obtained by solving Correlation Clustering (CC) problems are the basis for investigating deputies voting networks as well as questions about loyalty, leadership, coalitions, political crisis, and social phenomena such as mediation and polarization.

  20. Energy policy and regional inequalities in the Brazilian economy

    International Nuclear Information System (INIS)

    The objective of this paper is to evaluate the long-run regional impacts of the tariff policy of the Brazilian electric power sector. This sector has undergone a reform process that started in the 1990s. Since the beginning of the reform, two spatial trends of distribution of electric power tariffs have emerged among the Brazilian states, one of convergence and another of spatial divergence. These trends have been guided by the new electric power tariff policy and by the spatial features of the Brazilian economy, which is marked by a high degree of spatial concentration and hierarchical distribution of large markets. In addition, because of the presence of strong economies of scale, the recent electric power prices differentials might be caused by differentials in market size that provide better conditions for the achievement of economies of scale for electric power utility companies located in larger markets. Given the role of electric power as an important intermediate input in the production process and the interdependence between sectors, an Energy Interregional Computable General Equilibrium model was used to simulate the long-run regional impacts of electric power tariff policy in Brazil. The simulations showed that the heterogeneity of energy-intensity and the differentials of energy substitution drive the spatial impacts of changes in electric power prices. On the other hand, the recent trend of spatial dispersion of electric power prices might contribute to a decrease in the long-run economic growth and to an increase in the regional inequalities in Brazil. - Highlights: ► We model the regional impacts of tariff policy of the electric power sector in Brazil. ► High electric power tariffs increases in regions with higher electric-power-intensity. ► Heterogeneity of energy supply determines an unequal pattern of energy substitution. ► Low possibilities of energy substitution generate the most negative economic impacts

    Full Text Available The present work deals with the Brazilian exports of sawnwood of non-coniferous, veneer sheets and plywood, from 1961 to 2002. The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

    Full Text Available In this article, we analyze the main non-wood forest products from Brazilian savanna. We studied the behavior and the growth rates of production and prices of almond of babaçu, oil of copaiba, fiber of buriti, leaf of jaborandi, bark of barbatimão, bark of angico, fruit of mangaba, almonds of pequi, from 1982 to 2005. All the products exhibited decreasing production, with exception of the oil of copaiba and almonds of pequi, which showed positive growth rates: 12.9% and 8.5%, respectively. The analysis of prices for most products was not significant, except for barks of barbatimão and angico, and almonds of pequi, which showed positive trends: 10.9%, 6.7%, and 4.6%, respectively. We believe that results were not significant due to the severe variations of the Brazilian currency in the period. We conclude that pequi is the main product from savanna and that oil of copaiba has the biggest increase in the production because most of the production comes from the whole Brazilian Amazon region.

    Full Text Available Brazil is the world's largest producer of oranges and uses more than 70% of the harvested fruits in the production of juices. The amount of processed orange is growing about 10% per year, confirming the trend of the Brazilian citrus for juice production. This research aimed to investigate the Brazilian orange juice production chain from 2005 to 2009. Data from the amount of frozen juice produced and exported, international price of orange juice, and intermediate transactions were assessed in order to make possible selection of all interveners involved in the chain. The study using the Social Network Analysis (SNA showed that the densest relationships in the network are from exporters to importers and from orange growers to the orange processing industry. No difference was found in the values of the network geodesic distance or the clustering coefficients from 2005 to 2009. The degree of centrality increased steadily throughout the years indicating that the processing industry attempts to minimize the risks by centralizing the actions. A decrease in export of orange juice from 2007 (2.07 10(6 t to 2008 (2.05 10(6 t was found, probably due to the world's financial crisis with recovery in 2009. Since 2004, there has been an increase of nearly 10% per year in the market preference of concentrate juice (OFCJ when compared to the "not from concentrated" juice (NFC. Nowadays the NFC market represents nearly 50% of all Brazilian export which impacted in the logistic distribution and transportation issues.

    2004-01-01

    The Brazilian shield was assembled from a few Archean and Paleoproterozoic cratonic nuclei surrounded by Pan-African-Brasiliano mobile belts of Neoproterozoic age. While some of these mobile belts display a typical frontal collision tectonic style, others are dominated by transcurrent regimes, clearly indicating oblique collisional systems. This paper is an attempt to determine the mean orientation of the principal horizontal compressive stresses for each mobile belt, considering either the frontal or oblique convergence character. From these general observations a scheme with WNW - ESE to NWSE trends of the main compressive stress is proposed. We suggest that this trend represents the mean displacement vectors, according to a coherent kinematic picture for the amalgamation of the West Gondwana during the final stages of convergence of the Brasiliano belts, where WNW-ESE to NW-SE are the main directions of final closure.

  10. The interiorization of Brazilian violence, policing, and economic growth

    2015-09-01

    Full Text Available Brazilian homicide rates are among the highest in the world, inclusive of actual war zones. However, the character of Brazil's violence is changing. Recent analyses highlight a trend of dispersion of violence such that homicide rates in urban areas, traditionally the most violent places, have stagnated and declined while smaller cities and rural areas experienced a marked increase. An incipient explanation is that this trend is related to greater economic dynamism in the smaller cities, unaccompanied by increased policing. This article's empirical analysis uses locational Hoover indexes to express the dispersions of violence and economic activity, and also generates a proxy to measure the geographic concentration of police forces. Using panel data across all 26 states from 1995 to 2011, we find evidence of a correlation between dispersion of violence and GDP to less urban areas, and ambiguous results regarding police concentration.

    .585.012 originados por cáncer entre 1980 y 2006 fueron obtenidos en el Sistema de Informaciones sobre Mortalidad, y los demográficos, en el Instituto Brasileño de Geografía y Estadística. Las tasas de mortalidad general por cáncer y principales tipos fueron corregidas redistribuyendo proporcionalmente 50% de las muertes mal definidas y estandarizándolas por edad según población patrón mundial. Las curvas de tendencia para Brasil y grandes regiones fueron calculadas para capitales y demás municipios según sexo y evaluadas por medio de regresión linear simple. RESULTADOS: Entre los hombres, las tasas de mortalidad para los cánceres de pulmón, próstata y colorrectal fueron ascendentes; declinantes para el de estomago y estables para el de esófago. Entre las mujeres, hubo aumento de la mortalidad por cáncer de mama, pulmón y colorrectal; y disminución de las tasas para los cánceres de cuello uterino y de estomago. La evolución de la mortalidad varió entre las regiones del País, con patrones distintos entre las capitales y demás municipios. CONCLUSIONES: La corrección de las tasas de mortalidad con redistribución de los óbitos mal definidos aumentó la magnitud de la mortalidad general por cáncer en Brasil en cerca de 10% en 1980 y 5% en 2006. En los municipios del interior no se observó tendencia de disminución o estabilidad como en las capitales. Menor alcance de las acciones de prevención y la dificultad de acceso a servicios diagnóstico y tratamiento para cáncer para la población residente fuera de los grandes centros urbanos pueden explicar, en parte, estas diferencias.OBJECTIVE: To analyze the corrected trend of overall cancer mortality and leading sites in the state capitals and other municipalities of Brazil between 1980 and 2006.

    Full Text Available The literature on Initial Public Offerings (IPO is still little explored in Brazil, since the significant growth in the stock market occurred only recently. The purpose of this study is to identify the determining factors for the IPO of Brazilian companies, based on logistic regression methods and using a sample with private and public Brazilian companies. The results indicate that firms that undertook their IPO in the period were those that had been making significant investments, those that had the highest level of profitability and/or those that increased their level of indebtedness. The IPO was an alternative to improve the capital structure and/or raise funds to continue investing in their growth. The companies that went public were those that seized the opportunity offered in the period and the size of the companies was not significant for the IPO.

    AbstractThe science of psychology has been developing in the country of Brazil over the last 50 years. Nonetheless, most of the science in this field is published only in Brazilian journals. Overall, Brazil has yet to share its science with the international community. The potential to internationalize the science generated by Brazilian psychologists exists, though. One way would be to scale up the publication of Brazilian psychologists in international journals. Another way would be to inter...

    Full Text Available In 1912 the Brazilian diplomat and scholar Manuel de Oliveira Lima gave six lectures at Stanford University that encapsulated his views of what we now call Brazilian Studies. This article summarizes Oliveira Lima’s lectures. It then points out three aspects of Oliveira Lima’s worldview that are problematic from the perspective of the twenty-first century: his Eurocentrism; the unproblematic nature of the nation-state in his thinking; and his largely negative view of Brazil’s racial heritage. The third part of the essay analyzes three aspects of Oliveira Lima’s lectures that are still contemporary. These are the need to establish an adequate comparative context for the study of Brazil; the difficulty of justifying an academic discipline that revolves around the study of a single country; and the challenge of uniting disparate and specialized disciplines in order to appreciate Brazil’s complexity and trajectory in the modern world. In the conclusion, some guidelines for maintaining Brazilian Studies as a vibrant field are suggested.

  18. Alternative fuels: a Brazilian outlook

    International Nuclear Information System (INIS)

    This paper focuses on studies and information related to the use of alternative fuels in Brazil. The first part of this paper deals with the economics of different biomass technologies. The analysis consists of a careful costing of all operations involved. The study deals with wood, sugar cane and cassava, since these crops are exploited for commercial purposes in Brazil. Corn, although a useful raw material for producing ethanol in the United States, is not used for this purpose in Brazil. The second part deals with the industrial technologies used to convert biomass into energy. We consider several forms of energy derived from biomass and evaluate the economics of the processes. When opportune, we compare costs with those of the North American market. Market analysis and displacement of conventional energy are the subject of the third part of the paper. While the cost of each product is evaluated in most cases; in others the current market price is used. Finally, we raise the issues of institutional problems and planning and offer some conclusions on the future of biomass as an alternative energy source. The technological discussion in this paper is based on the Brazilian experience in producing ethanol and other fuels from biomass. It is possible to extrapolate the Brazilian experience to other developing countries. The observations made in this chapter are based on the conditions prevalent in the Brazilian south-central agricultural region, specifically the state of Sao Paulo.

  20. Competitiveness in the Brazilian oil industry. The Brazilian 'oil diamond'

    International Nuclear Information System (INIS)

    It is recognized the economic benefits that might follow the opening process of the Brazilian oil and natural gas industry, which shall experience a fast expansion with the arrival of national and international private investors. However, we should not neglect the broader impact of this process on the future development of all that cluster of national agents that lived around and served the former national oil monopoly, managed by the Brazilian National Oil Company, Petrobras. This work focuses on this larger perspective, discussing about the capacity of Brazil to sustain and expand its competitiveness in the oil business as well as to obtain the maximum economic development from the exploration of its oil and gas reserves. We adopt the work of Michael Porter, from the University of Harvard, about the Competitive Advantage of Nations, as a theoretical model to analyze the Competitive Advantage of Brazil in the global oil industry. By introducing the concept of ''oil diamond'', adapted from the notion introduced by this author, we develop a new understanding of national competitiveness in the oil sector. In this paper, we present the general model as well as a brief characterization of the results found for Brazil Subsequently, we focus on just one leg of the model, for which we discuss, with more detail, about the competitive condition of the country in the opening-up scenario. This leg regards the so-called supporting and supplementary industries that constitute what is denominated in the French tradition the ''para petroleum'' industry. We analyze the conditions for the Brazilian domestic ''para petroleum industry'' to survive and grow in the new competitive environment. (authors)

    The Brazilian National Institute for Space Research (INPE) has been monitoring the Brazilian Legal Amazon deforestation through the PRODES project since 1988, providing yearly deforestation maps based on about 60 m spatial resolution. Additionally, INPE's Real Time Deforestation Detection System (DETER) has monthly indicating, based on high temporal resolution satellite data, where and when the forest is being felled. However, those monitoring processes are mainly based on visual interpretation, which is accurate but a hard and time consuming task. The Spectral-Temporal Analysis by Response Surface (STARS), which synthesizes the full information content of a multitemporal-multispectral remote sensing image dataset to represent the spectral variation over time of features on the Earth's surface, comes as an alternative for applications in land cover change detection, such as deforestation in the Brazilian Amazon. Thus, since deforestation process presents particular spectral changes over time, spectral-temporal response surfaces could be fitted to describe its change patterns, allowing to detect deforested areas. In this context, this work aims to apply the STARS to detect deforestation in the Brazilian Amazon, using Landsat-5 multitemporal-multispectral images. Four georeferenced images covering about 3.400 square kilometres within the Mato Grosso State, Brazil (13°17'S; 55°50'W to 14°20'S; 55°10'W) were used: one Multispectral Scanner (MSS) image from 1980 (bands 4, 5, 6 and 7 - 60 m spatial resolution); and three Thematic Mapper (TM) images from 1990, 2000 and 2010 (bands 1, 2, 3, 4, 5 and 7 - 30 m spatial resolution). The MSS image was resampled to 30 m to match the TM spatial resolution. All images were then used as input for STARS resulting in a Multi-Coefficient Image (MCI) with 10 synthetic bands formed by the 10 fitted coefficients of a Polynomial Trend Surface (PTS) model with degree equal to three. The MCI was used as input for a decision tree (DT

    Full Text Available Abstract Background Differences in sex hormone levels among populations might contribute to the variation in breast cancer incidence across countries. Previous studies have shown higher breast cancer incidence and mortality among Japanese Brazilians than among Japanese. To clarify the difference in hormone levels among populations, we compared postmenopausal endogenous sex hormone levels among Japanese living in Japan, Japanese Brazilians living in the state of São Paulo, and non-Japanese Brazilians living in the state of São Paulo. Methods A cross-sectional study was conducted using a control group of case-control studies in Nagano, Japan, and São Paulo, Brazil. Participants were postmenopausal women older than 55 years of age who provided blood samples. We measured estradiol, estrone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, testosterone and free testosterone by radioimmunoassay; bioavailable estradiol by the ammonium sulfate precipitation method; and sex hormone-binding globulin (SHBG by immunoradiometric assay. A total of 363 women were included for the present analyses, comprising 185 Japanese, 44 Japanese Brazilians and 134 non-Japanese Brazilians. Results Japanese Brazilians had significantly higher levels of estradiol, bioavailable estradiol, estrone, testosterone and free testosterone levels, and lower SHBG levels, than Japanese. Japanese Brazilians also had significantly higher levels of bioavailable estradiol, estrone and DHEAS and lower levels of SHBG and androstenedione than non-Japanese Brazilians. Levels of estradiol, testosterone and free testosterone, however, did not differ between Japanese Brazilians and non-Japanese Brazilians. These differences were observed even after adjustment for known breast cancer risk factors. We also found an increase in estrogen and androgen levels with increasing body mass index, but no association for most of the other known risk factors. Conclusions We found higher levels of

  9. The Causes of Fiscal Transparency: Evidence in the Brazilian States

    Full Text Available The transparency of governments to their citizens is seen as a necessary factor in democratic accountability and, consequently, in the consolidation of democracy. Although the importance of transparency in government is often highlighted, its causes are still unknown, especially in the Brazilian context. Following the trend of international empirical research, this exploratory study investigates the relationships between three sets of variables (current and past fiscal variables, socioeconomic variables and political variables and fiscal transparency in the Brazilian subnational context. To identify the relationship between fiscal, socioeconomic and political variables and fiscal transparency, the multiple linear regression technique was used. Prior to conducting the regression using the method of ordinary least squares, factor analysis was used, aiming to group the fiscal and socioeconomic variables into factors not only to reduce their quantity but also to eliminate their multicollinearity problems. Political variables, due to their qualitative nature, remained in their original form. The factor analysis sorted the variables into two groups: fiscal and socioeconomic factors. Because multiple regression allows only for the evaluation of the relationship between the parties included in the sample and the reference party, an F test was used to assess differences in the level of transparency among political parties. The results indicated that fiscal and socioeconomic variables explain the transparency levels of the Brazilian States. However, the political variables were not significant, indicating that the disclosure of fiscal information in Brazil seems not to be influenced by political ideologies. Furthermore, it is evident that the lack of a regulatory model of transparency in the budget process leads States to disclose a great deal of information about budget execution. Finally, the findings indicate that as an instrument for democratic

  10. Natural-gas-powered thermoelectricity as a reliability factor in the Brazilian electric sector

    International Nuclear Information System (INIS)

    The introduction of natural-gas-powered thermoelectricity into the Brazilian generation sector can be considered as a very complex energy, economic, regulatory and institutional revision. Brazil is a country with very specific characteristics in electricity generation, as approximately 80% of the generating capacity is based on hydroelectricity, showing strong dependency on rain and management of water reservoirs. A low rate of investment in the Brazilian Electricity Industry in the period of 1995-2000, associated with periods of low rainfall, led to a dramatic lowering of the water stocks in the reservoirs. With this scenario and the growing supply of natural gas, both from within Brazil and imported, natural gas thermal electric plants became a good option to diversify the electrical supply system. In spite of the Brazilian Government's efforts to install such plants, the country was faced with severe electricity rationing in 2001. The objective of this work is to show the need to continue with the implementation of natural gas thermal electricity projects, in a manner that allows flexibility and guarantees greater working reliability for the entire Brazilian electricity sector. Taking into account the world trend towards renewable energy, the perspectives of usage of biofuels in the Brazilian Energy Matrix and in electrical energy generation are also analyzed. The very issue of electrical power efficiency in Brazil and its challenges and strategic proposals from the standpoint of Government Programs and results provided so far are presented. The technological constraints in order to put on stream the thermal electric plants are also analyzed. The article concludes with a positive perspective of the usage of natural gas as to be the third pillar in the Brazilian Energy Matrix for the years to come

Possible trends of sense production based on reading are looked for in the set of narratives, considering that, in the organization of their components, such texts carry a potential of meanings which are updated at each reading. Since the narratives cover recent historical events, it is concluded that social memory and history play a peculiar role as mechanisms external to narrative that reflect their internal mechanisms and possibilities of history meaning. In this analysis, elements of language studies and theory of history, with regard to its teaching, are broadly present. How to reference this article Rocha, H. (2015.

    Full Text Available INTRODUCTION: Circulatory Diseases (CD are the major cause of death among the elderly population in Brazilian Amazon. OBJECTIVE: to analyze standardized mortality rates of diseases of the circulatory system (DCS, according to the main causes of death among the elderly, in microregions of the Brazilian Amazon, in the period of 1998 - 2007. METHODS: ecological study of mortality rates distribution standardized by CD and corrected by deaths from poorly defined causes among the elderly (> 65 years of age who lived in Brazilian Amazon in the period of 1998 - 2007. The analysis were carried out by the linear regression, trend, and spatial distribution of Kernel. RESULTS: We verified an increasing trend in mortality by CD (β1 = 28.34 p = 0.01, due to the increasing trend in the States of Maranhão and Tocantins. The central region of Mato Grosso, Northern Tocantins, Eastern Pará and Southwestern Maranhão present hot spots with the highest mortality rates. Males present higher rates when compared to females all over the region; rates of mortality due to acute myocardial infarction and hypertensive disease present the same spatial standard of the CD group and the rates of cerebrovascular diseases present a different spatial distribution standard. Increment in mortality rates according to age was observed: the greater the age, the higher is mortality by CD. CONCLUSION: The Brazilian Amazon presents an increasing trend with high rates of mortality by the circulatory diseases, and the geographic areas with the highest rates are around the Brazilian Amazon, in the states of Tocantins, Maranhão and Mato Grosso.

    Sustainable intensification of agriculture is one of the main strategies to provide global food security. However, its implementation raises enormous political, technological, and social challenges. Meeting these challenges will require, among other things, accurate information on the spatial and temporal patterns of agricultural land use and yield. Here, we investigate historical patterns of agricultural land use (1940-2012) and productivity (1990-2012) in Brazil using a new high-resolution (approximately 1 km(2) ) spatially explicit reconstruction. Although Brazilian agriculture has been historically known for its extensification over natural vegetation (Amazon and Cerrado), data from recent years indicate that extensification has slowed down and was replaced by a strong trend of intensification. Our results provide the first comprehensive historical overview of agricultural land use and productivity in Brazil, providing clear insights to guide future territorial planning, sustainable agriculture, policy, and decision-making.

    Four decades of the Brazilian nuclear history have been analysed with special emphasis placed on government policy and its repercussion on public opinion. The implications of the new constitutional regulations which rule the issue are discussed. it is also studied the change in the nuclear program structure, enforced in August 1988. At different times, the government decisions on nuclear energy could be classified as miser, extravagant, dissimulated and frank, successively. Their aftermaths, which show little consistency with the expectations laid on them, have led to discredit by part of the society, which is controlled by a scientific - intellectual elite. However, recent successes are likely to reverse this trend, if the government explores them properly. (author)

    This work studies the Zipf Law for cities in Brazil. Data from censuses of 1970, 1980, 1991 and 2000 were used to select a sample containing only cities with 30,000 inhabitants or more. The results show that the population distribution in Brazilian cities does follow a power law similar to the ones found in other countries. Estimates of the power law exponent were found to be 2.22 +/- 0.34 for the 1970 and 1980 censuses, and 2.26 +/- 0.11 for censuses of 1991 and 2000. More accurate results were obtained with the maximum likelihood estimator, showing an exponent equal to 2.41 for 1970 and 2.36 for the other three years.

  7. Futebol mulato: racial constructs in Brazilian football

    Directory of Open Access Journals (Sweden)

    Tiago Fernandes Maranhao

    2011-05-01

    Full Text Available The aim of this paper is to review Gilberto Freyre’s ideas about futebol mulato and the way these ideas have spread the notion of the Brazilian mulatto as a symbol of a ‘racial democracy’, unique in Brazil, around the world. The notion first appeared in 1938 in an article by Freyre for the Diários Associados, an important Brazilian newspaper. Football (soccer was employed by Freyre as the special arena where the multiracial Brazilian nation could shine and show the world a different way of being, opposed to the white and ‘rational’ way of European football. In Freyre’s work, the so-called ‘football-art’ was compared to poetry, while the European style was equated with prose. This essay argues that Freyre’s ideas were useful in constructing the Brazilian identity, a nation of harmony in all its aspects, including the area of race, and how the idea of the mulatto has been used to minimise social disparities within Brazilian society. Freyre’s ideas remain contemporary; many Brazilian intellectuals still refer to these concepts. As well, the press in this huge country, and especially in World Cup years, uses the concepts of mulatto and football-art to characterize Brazil and differentiate it from other countries.

    Full Text Available Significant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

    Background: Studies have shown different mortalities due to cardiovascular diseases (CVD), ischemic heart disease (IHD) and cerebrovascular diseases (CbVD) in the five Brazilian regions. Socioeconomic conditions of those regions are frequently used to justify differences in mortality due to those diseases. In addition, studies have shown a reduction in the differences between the mortality rates of the five Brazilian regions. Objective: To update CVD mortality data in women and men in the five Brazilian regions. Methods: Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and Ministry of Health. Risk of death was adjusted by use of the direct method, with the 2000 world standard population as reference. We analyzed trends in mortality due to CVD, IHD and CbVD in women and men aged ≥ 30 years in the five Brazilian regions from 1980 to 2012. Results: Mortality due to: 1) CVD: showed reduction in the Northern, West-Central, Southern and Southeastern regions; increase in the Northeastern region; 2) IHD: reduction in the Southeastern and Southern regions; increase in the Northeastern region; and unchanged in the Northern and West-Central regions; 3) CbVD: reduction in the Southern, Southeastern and West-Central regions; increase in the Northeastern region; and unchanged in Northern region. There was also a convergence in mortality trends due to CVD, IHD, and CbVD in the five regions. Conclusion: The West-Central, Northern and Northeastern regions had the worst trends in CVD mortality as compared to the Southeastern and Southern regions.

    1991-12-01

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

  17. Permeability measuremens of brazilian Eucalyptus

    Full Text Available The permeability of Brazilian Eucalyptus grandis and Eucalyptus citriodora wood was measured in a custom build gas analysis chamber in order to determine which species could be successfully treated with preservatives. Liquid permeability was tested using an emulsion of Neen oil and a control of distillated water. Air was used to test the gas phase permeability. For both Eucalyptus grandis and Eucalyptus citriodora, the longitudinal permeability of gas was shown to be about twice as great as the liquid phase permeability. No radial permeability was observed for either wood. The permeability of air and water through the sapwood of Eucalyptus grandis was greater than that through the sapwood of Eucalyptus citriodora. The permeability of neen oil preservative through the sapwood of Eucalyptus grandis was also greater than through the sapwood of E. Citradora, but the difference was not statistically significant. Scanning Electron Microscopy images showed that the distribution and obstruction in the vessels could be correlated with observed permeability properties. Irrespective of the causes of differences in permeability between the species, the fluid phase flux through the sapwood of both species was significant, indicating that both Eucalyptus grandis and Eucalyptus citriodora could be successfully treated with wood preservative.

    Full Text Available Reflecting on the importance of multiculturalism in teaching process and observing the otherness are primarily a challenge. This enables us to rethink what we have within ourselves, also to reconstitute memories involving discriminatory and unethical attitudes, which takes place in social fellowship. Based on the studies of Walsh (2007, 2009, Gomes (2007 and Tavares (2011, this work relies on decoloniality studies, mainly on the relevance of the history of Africa and Africanness in Brazilian education. Our corpus of analysis is found in the "Diretrizes Curriculares Nacionais para a Educação Básica" (DCN, 2013, the Brazilian Legislative Syllabus for Basic Education. Our focus is on the chapters concerning the Native-Brazilian and Quilomboa Education and ethnic-racial relations. Our most important aims are: to show the intercultural theoretical framework in which they are based on; to understand the immediate link established between the Native-Brazilian education and intercultural perspective; to clarify how the African diaspora was carried out in this particular case. Based on some Excel resources we were able to: 1 stablish the predominance of functional framework of interculturalism throughout these chapters, along with some critical features of interculturalism, as the issue of curricular decoloniality; 2 observe the established relationship between bilingualism and multiculturalism in the guidelines of Native-Brazilian education; and 3 identify a search for an effective inclusion of Africanness in curricula supported by the historical recognition and visibility of their sociocultural contribution.

    Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining some requirements of the Brazilian Environmental Regulator (IBAMA). The RBMN Project (Repository for Low and Intermediate-Level Radioactive Wastes) aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (author)

O estudo foi realizado em uma amostra de 203.455 e 239.700 participantes da PNAD 1998 e 2003, respectivamente. As condições de saúde e função física, uso de serviços de saúde e filiação a plano de saúde daqueles pertencentes ao quintil inferior da distribuição da renda domiciliar per capita foram comparadas às daqueles com renda mais alta, utilizando-se métodos multivariados de análise. Os resultados mostraram que nos dois anos considerados, os indivíduos no estrato mais baixo de renda apresentavam piores condições de saúde, pior função física e menor uso de serviços de saúde, tanto na faixa etária de 20-64 quanto na de > 65 anos de idade. As forças das associações entre renda domiciliar per capita, condições de saúde e uso de serviços de saúde não se modificaram entre 1998 e 2003, indicando que não houve alterações nas desigualdades sociais em saúde no período estudado. A persistência dessas desigualdades aponta para a ineficiência de políticas, nos últimos cinco anos, que as reduzissem.The aim of this study was to verify whether health inequalities among Brazilian adults (20-64 years and old-aged (> 65 years have changed from 1998 to 2003.

    Full Text Available This research note examines the results of the 2014 elections focusing on the National Congress. Its main objective is to ponder over common claims and predictions regarding the future of Brazilian politics. Beyond agreements and alliances involved in the electoral dispute, President Dilma Rousseff once again shall face the political challenges and dilemmas of Brazilian presidentialism, namely, how to create and manage government coalitions capable of implementing a coherent political program with a fragmented and heterogeneous Congress. The critical examination of the current hypotheses on the latest elections, especially concerning parliamentary fragmentation and a shift towards the right-wing, will serve as a compass attempting to formulate possible answers to such a fundamental problem in Brazilian politics.

  5. Brazilian sandy beach macrofauna production: a review

    2012-12-01

    Full Text Available The state of the art of the studies on the production of Brazilian sandy beach macrofauna was analyzed on the basis of the data available in the literature. For this purpose, the representativeness of the production dataset was examined by latitudinal distribution, degree of exposure and morphodynamic state of beaches, taxonomic groups, and methods employed. A descriptive analysis was, further, made to investigate the trends in production of the more representative taxonomic groups and species of sandy beach macrofauna. A total of 69 macrofauna annual production estimates were obtained for 38 populations from 25 studies carried out between 22º56'S and 32º20'S. Production estimates were restricted to populations on beaches located on the southern and southeastern Brazilian coast. Most of the populations in the dataset inhabit exposed dissipative sandy beaches and are mainly represented by mollusks and crustaceans, with a smaller number of polychaetes. The trends in production among taxonomic groups follow a similar pattern to that observed on beaches throughout the world, with high values for bivalves and decapods. The high turnover rate (P/B ratio of the latter was due to the presence of several populations of the mole crab Emerita brasiliensis, which can attain high values of productivity, in the dataset. Most of the studies focus on the comparison of production and, especially, of P/B ratio according to life history traits in populations of the same species/taxonomic group. Despite the importance of life history-production studies, other approaches, such as the effect of man-induce disturbances on the macrofauna, should be undertaken in these threatened environments.O estado da arte dos estudos de produção da macrofauna de praias arenosas brasileiras foi analisado a partir de informações disponíveis na literatura. Para essa finalidade, a representatividade dos dados de produção foi examinada de acordo com a distribuição latitudinal

    Full Text Available The purpose of the present study was to translate and adapt the Berg balance scale, an instrument for functional balance assessment, to Brazilian-Portuguese and to determine the reliability of scores obtained with the Brazilian adaptation. Two persons proficient in English independently translated the original scale into Brazilian-Portuguese and a consensus version was generated. Two translators performed a back translation. Discrepancies were discussed and solved by a panel. Forty patients older than 65 years and 40 therapists were included in the cultural adaptation phase. If more than 15% of therapists or patients reported difficulty in understanding an item, that item was reformulated and reapplied. The final Brazilian version was then tested on 36 elderly patients (over age 65. The average age was 72 years. Reliability of the measure was assessed twice by one physical therapist (1-week interval between assessments and once by one independent physical therapist. Descriptive analysis was used to characterize the patients. The intraclass correlation coefficient (ICC and Pearson's correlation coefficient were computed to assess intra- and interobserver reliability. Six questions were modified during the translation stage and cultural adaptation phase. The ICC for intra- and interobserver reliability was 0.99 (P < 0.001 and 0.98 (P < 0.001, respectively. The Pearson correlation coefficient for intra- and interobserver reliability was 0.98 (P < 0.001 and 0.97 (P < 0.001, respectively. We conclude that the Brazilian version of the Berg balance scale is a reliable instrument to be used in balance assessment of elderly Brazilian patients.

    Climate Change, Impacts and Vulnerabilities in Brazil: Preparing the Brazilian Northeast for the Future; Natal, Brazil, 27 May to 01 June 2012 The variability of the semiarid climate of the Brazilian northeast has enormous environmental and social implications. Because most of the population in this area depends on subsistence agriculture, periods of severe drought in the past have caused extreme poverty and subsequent migration to urban centers. From the ecological point of view, frequent and prolonged droughts can lead to the desertification of large areas. Understanding the causes of rainfall variability, in particular periods of severe drought, is crucial for accurate forecasting, mitigation, and adaptation in this important region of Brazil.

    Full Text Available There is no furthest behind infrastructure in Brazil than the lack of sewage disposal, particularly the shortage of services for treating water, and for collecting and treating waste. The scarcity of these essential services to human dignity has been plaguing millions of Brazilians, as indicated by the data of the National Sanitation Information System 2014. We have 35 million Brazilians without access to services for treating water, where half the population has no sewage collection and only 40% of the waste collected in this country is treated. The shortage of sewage disposal affects all of us.

    Full Text Available OBJECTIVE: To compare the motor development of infants from three population samples (Brazil, Canada and Greece, to investigate differences in the percentile curves of motor development in these samples, and to investigate the prevalence of motor delays in Brazilian children. METHODS: Observational, descriptive and cross-sectional study with 795 Brazilian infants from zero to 18 months of age, assessed by the Alberta Infant Motor Scale (AIMS at day care centers, nurseries, basic health units and at home. The Brazilian infants' motor scores were compared to the results of two population samples from Greece (424 infants and Canada (2,400 infants. Descriptive statistics was used, with one-sample t-test and binomial tests, being significant p≤0.05. RESULTS: 65.4% of Brazilian children showed typical motor development, although with lower mean scores. In the beginning of the second year of life, the differences in the motor development among Brazilian, Canadian and Greek infants were milder; at 15 months of age, the motor development became similar in the three groups. A non-linear motor development trend was observed. CONCLUSIONS: The lowest motor percentiles of the Brazilian sample emphasized the need for national norms in order to correctly categorize the infant motor development. The different ways of motor development may be a consequence of cultural differences in infant care.

    Full Text Available With the globalization process, the world-wide nations are having an increase of the international trade. Brazil has, each time more, used the agribusiness as a strategy of insertion in the world-wide economy. The exportations of Brazilian agricultural productscome playing an important paper in the supplying revenues and increase of the domestic income, but a visible problem of the agribusiness for exportation is related to logistic. In theworld-wide marketplace, Brazil presents comparative advantages in the production of agricultural products in relation to the other world-wide producers, but it loses in logistic costs. The importance of this work is in characterizing the logistic problems of the Brazilian exportation of one of the most important commodities national, the soybeans. The soybeans is the agricultural product that more generates volume of exportation for Brazil, demanding sufficiently of the logistic structure of the country. For accomplishment of this work, it was used an general bibliographical research, where if it carried through a detailed survey of themain problems, causes, costs and solutions for the flowing of the soybeans in Brazilian for exportation. From the development of this work, it was perceived that the challenges of the logistic of the soybeans are many and that the resolution of these problems will increase the Brazilian international competitiveness, increasing the trustworthiness in the delivery times and reducing the costs of the inefficiencies in the exportation process.

    Full Text Available ABSTRACT The present study aims to study earnings management in a significant sample of 123 banks in the Brazilian market between 2001 and 2012. Given the important role that banks play in a country's economy, it is important to understand that there are discretionary factors involved in the reporting of a financial institution's profitability. Credit provisioning guidelines for Brazilian financial institutions are described in Resolution 2682/99 of the National Monetary Council (Conselho Monetário Nacional. Because of the discretion allowed in this resolution, loan loss provision is used as instrument of earnings management, which is not an illegal practice, but this behavior does affect the risk perception of agents and analysts, and they should be aware of it and understand it. We found that credit provisioning is used as an earnings management mechanism to smooth the net income of Brazilian financial institutions. Brazilian banks tend to avoid not only negative net income pre-loan loss provisions and taxes, but also negative net income pre-loan loss provisions and taxes in relation to the previous period. Contrary to the previous studies, it is not clear if banks avoid lower net income pre-loan loss provisions and taxes than a given peer group.

  15. The Brazilian business and growth cycles

    Chauvet Marcelle

    2002-01-01

    Full Text Available This paper uses several produceres to date and analyse the Brazilian business and growth cycles. In particular, a Markov switching model is fitted to quarterly and annual real production data. The smoothed probabilities of the Markov states are used as predictive rules to define different phases of cyclical fluctuations of real Brazilian production. The results are compared with different non-parametric rules. All methods implemented yield similar dating and reveal asymmetries across the different states of the Brazilian business and growth cycles, in which slowdowns and recessions are short and abrupt, while high growth phases and expansions are longer and less steep. The resulting dating of the Brazilian economic cycles can be used as a reference point for construction and evaluation of the predictive performance of coincident, leading, or lagging indicators of economic activity. In addition, the filtered probabilities obtained from the Markov switching model allow early recognition of the transition to a new business cycle phase, wich can be used, for example, for evaluation of the adequate strength and timing of countercyclical policies, for reassessment of projected sales or profits by businesses and investors, or for monitoring of inflation pressures.

  16. RMB. The new Brazilian multipurpose research reactor

    International Nuclear Information System (INIS)

    Brazil has four research reactors (RR) in operation: IEA-R1, a 5 MW pool type RR; IPR-R1, a 100 kW TRIGA type RR; ARGONAUTA, a 500 W Argonaut type RR, and IPEN/MB-01, a 100 W critical facility. The first three were constructed in the 50's and 60's, for teaching, training, and nuclear research, and for many years they were the basic infrastructure for the Brazilian nuclear developing program. The last, IPEN/MB-01, is the result of a national project developed specifically for qualification of reactor physics codes. Considering the relative low power of Brazilian research reactors, with exception of IEAR1, none of the other reactors are feasible for radioisotope production, and even IEA-R1 has a limited capacity. As a consequence, since long ago, 100% of the Mo-99 needed to attend Brazilian nuclear medicine services has been imported. Because of the high dependence on external supply, the international Moly-99 supply crisis that occurred in 2008/2009 affected significantly Brazilian nuclear medicine services, and as presented in previous IAEA events, in 2010 Brazilian government formalized the decision to build a new research reactor. The new reactor named RMB (Brazilian Multipurpose Reactor) will be a 30 MW open pool type reactor, using low enriched uranium fuel. The facility will be part of a new nuclear research centre, to be built about 100 kilometres from Sao Paulo city, in the southern part of Brazil. The new nuclear research centre will have several facilities, to use thermal and cold neutron beams; to produce radioisotopes; to perform neutron activation analysis; and to perform irradiations tests of materials and fuels of interest for the Brazilian nuclear program. An additional facility will be used to store, for at least 100 years, all the fuel used in the reactor.

  19. Spatial and temporal vegetation change in Southern Brazilian Amazon using GIS and NOAA /AVHRR data

    Kazadi, S.; Yoshikawa, S.

    2007-05-01

    Over the past two decades, environmental alteration in the Amazon Basin due to land development, population increase, and the consequent deforestation, has become a serious ecological problem in this region known to be, both climatologically and biogenetically, one of the most important regions in the world. In Mato Grosso, the Brazilian state with the highest deforestation rate, vegetation cover change has been reported to occur over large areas due to the introduction of large-scale mechanized agriculture, extensive cattle ranching and slash-and-burn cultivation. Spatial and temporal land cover (vegetation) change is noted to potentially set up temperature increase and rainfall decrease. We stress on the importance of vegetation change information as crucial inputs for eco-climatic analysis of these spatial patterns of change and their temporal trend at local scale, as well as for real-time monitoring or detection of the deforestation events for appropriate action by the Brazilian government. In this study, Principal Component Analysis (PCA) is performed onto NOAA AVHRR remote-sensed and multi- spectral data covering the 1981-2003 period, using GIS. Our investigation focuses on developing a vegetation quantification algorithm for change detection in the vegetation cover over every few years, using the PCA first component, which is shown to characterize the overall vegetation cover types. Land cover features and their spatio-temporal change over the Southern Brazilian Amazon are analyzed and discussed, and their relationships with global and regional eco-climatic phenomena is highlighted.

  20. Brazilian Amazon Roads and Parks: Temporal & Spatial Deforestation Dynamics

    2011-12-01

    Heterogeneous Forest Impacts of Transport Infrastructure: spatial frontier dynamics & impacts of Brazilian Amazon road changes Prior research on road impacts has almost completely ignored heterogeneity of impacts and as a result both empirically understated potential impact and missed policy potential. We note von Thunen's model suggests not only heterogeneity with distance from market but also specifically road impacts rising then falling with distance ('non-monoThunicity') Endogenous development and partial adjustment dynamics support this for the short run. Causal effects result from studying Brazilian Amazon deforestation (1976-87, 2000-04) using matching for short-run responses to lagged new roads changes (1968-75, 1985-00). We show the critical role of prior development, proxied by 1968 and 1985 road distances, for which exact matching addresses development trends and transforms impact estimates. Splitting the sample on this measure finds confirmation of the nonmonotonic predictions: new road impacts are relatively low if a prior road was close, such that prior transport access and endogenous development dynamics compete with the new road for influence, but also if a prior road was far, since first-decade adjustment in pristine areas is limited; yet in between these bounds, investments immediately raise deforestation significantly. This pattern helps to explain lower estimates within research on a single average impact. It suggests potential for REDD if a country chooses to shift its spatial transport networks. Protected Areas & Brazilian Amazon Deforestation: modeling and testing the impacts of varied PA strategies We model and then estimate the impacts of multiple types of protected areas upon 2000 - 2004 deforestation in the Brazilian Amazon. Our modeling starts with federal versus state objectives and predicts differences in both choice and implementation of each PA strategy that we examine. Our empirical examination brings not only breakdowns sufficient

    Pedro Lucas de Resende Melo

    2015-04-01

    Full Text Available The primary goal of this paper is to comprehend the fundamental organizational differences between Brazilian franchise chains that only operate in the home market and Brazilian franchise chains that operate internationally. The sample chosen for this study comprehends 96 Brazilian franchises operating in the home market and 67 franchises with international operations; logistic regression was used to analyze data obtained from these sources. Our findings suggest that the development of a brand in international operations can be strategic for certain Brazilian franchise chains; this seems to be, however, a scarce resource for many franchises and it could be developed through international operations. With regard to the fees charged, the outcomes demonstrate that Brazilian franchises with international operations tend to charge lower fees from its franchisees to install new units. Regarding the monitoring and control of franchises, there is evidence that the monitoring capability is one of the determining factors in the development of Brazilian franchises international operations.

  6. Seasonal hydroclimatic impacts of Brazilian sugar cane expansion

    Georgescu, M.; Lobell, D. B.; Field, C. B.; Mahalov, A.

    2012-12-01

    Brazil is the leading producer of sugar cane in the world with roughly half used for ethanol production. Because of suitable climatic growing conditions, the majority of biofuel production is derived from sugar plantations in southeastern states. Anticipated increases in global demand for biofuels are expected to lead to future sugar cane expansion extending into Brazilian pasturelands and native cerrado. Prior to undergoing large-scale expansion an evaluation of impacts on the region's hydroclimate is warranted. Using a suite of multi-year ensemble-based simulations with the WRF modeling system, we quantify hydroclimatic consequences of sugar cane expansion across portions of south-central Brazil. Conversion from current land use to sugar cane causes opposing seasonal impacts on near-surface temperature. Proggresively greater cooling is simulated during the course of the growing season, followed by an abrupt warming shift post-harvest. Although seasonal impacts on near-surface temperature are significant, with cooling of 1C occurring during the peak of the growing season followed by warming of similar magnitude, impacts are small when annually averaged. Ensemble mean differences between the imposed sugar cane expansion and non-expansion scenario are suggestive of a drying precipitation trend, yet large uncertainty among individual members precludes definitive statements about impacts on the region's rainfall.

    Dulce de leche samples available in the Brazilian market were submitted to sensory profiling by quantitative descriptive analysis and acceptance test, as well sensory evaluation using the just-about-right scale and purchase intent. External preference mapping and the ideal sensory characteristics of dulce de leche were determined. The results were also evaluated by principal component analysis, hierarchical cluster analysis, partial least squares regression, artificial neural networks, and logistic regression. Overall, significant product acceptance was related to intermediate scores of the sensory attributes in the descriptive test, and this trend was observed even after consumer segmentation. The results obtained by sensometric techniques showed that optimizing an ideal dulce de leche from the sensory standpoint is a multidimensional process, with necessary adjustments on the appearance, aroma, taste, and texture attributes of the product for better consumer acceptance and purchase. The optimum dulce de leche was characterized by high scores for the attributes sweet taste, caramel taste, brightness, color, and caramel aroma in accordance with the preference mapping findings. In industrial terms, this means changing the parameters used in the thermal treatment and quantitative changes in the ingredients used in formulations.

    Full Text Available We study the interaction between forward and spot electricity markets in a scenario where buyers and sellers are price takers in the forward market and trade through marketers, who play a Cournot game. Our model’s main features come from the Brazilian electricity market, where a free contract market coexists with a regulated contract market, and the spot price is the output of a stochastic dynamic algorithm. We are able to show that the price of energy bought (sold forward decreases (increases with the number of marketers, and that, as a result, full hedging is achieved in the limit. We also investigate the effects on prices of changes in the number of market participants and in aggregate consumption and supply, an exercise that yields important policy recommendations for the Brazilian regulator.

  17. Radioactivity in Brazilian Manioc-root Flour

    International Nuclear Information System (INIS)

    The results are presented of a nation-wide survey programme aimed at determining the radioactivity in a widely used, inexpensive Brazilian food. Well-established nuclear techniques were employed to measure the specific activities of 226Ra, 228Ra, 40K, and 137Cs in fifty-six samples of manioc-root flour gathered in 20 Brazilian states. Whereas the activities for 40K were much the same as those found in other vegetables, the activities of radium proved to be in significant amounts: 0.2-7.2 Bq.kg-1 for 226Ra, and 0.3-34 Bq.kg-1 for 228Ra. Annual effective doses caused by the ingestion of manioc flour were also assessed taking into account the diet figures available for ten Brazilian states. For the adult public of those states, the radium (226Ra + 228Ra) present in manioc will be responsible for average doses ranging from 3 to 106 μSv.y-1. However, low-income people living in the states of Rio Grande do Norte, Ceara and Paraiba (northeast Brazil) could receive doses in the range from 28 to 893 μSv.yr-1. (author)

    Full Text Available This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC (n = 15 and naturally ventilated (NV (n = 15 classrooms. The parameters of interest were indoor carbon dioxide (CO2, temperature, relative humidity (RH, wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively. The average indoor airborne dust concentration exceeded the Brazilian standards (<80 µg/m3 in both NV and AC classrooms. The levels of CO2 in the AC rooms were significantly different from the NV rooms (1433.62 ± 252.80 and 520.12 ± 37.25 ppm, respectively. The indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

    2003-08-01

    We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

    This ethnographic examination of Brazilian immigrant perspectives regarding healthcare in the U.S. included participant observation and interviews with 42 Brazilian transnationals. Data were analyzed using Agar's approach. Findings show that Brazilians accessed allopathic care only as a last resort after self-treatment strategies failed, that they tended to feel that diagnostic testing, referrals, and symptom-relieving prescriptions were imperative to good care, and that they expected more personal warmth, continuity of care, and more affectionate verbal and nonverbal cues than their U.S. clinicians provided. Recommendations to improve quality of healthcare to Brazilian transnationals in the USA are discussed. PMID:19172985

    2014-07-01

    Full Text Available Over the last years, management have been facing a series of profound changes in trends coming and going, one being more productive than other or causing more damage when applied improperly. The paper focuses on the last trends in management that have evolved in the last years, trends that have been marked by a Darwinian business environment and made more unforgiving since the financial crisis and the innovations in technology, social media and management philosophy. The paper will present and describe the most important new trends in management that enabled select organisations to remain competitive and overcome the multiple difficulties caused by the ever-changing economy based on a qualitative research. From the “outside innovation” that is considered always to be the key in overcoming the obstacles facing an organization, to the new buzzword “design”, that is said to ensure the organization long-term competitive advantage, the paper will analyse new trends and also will be describing the impact they have on the welfare of the organization. The research has also shown that managers tend to put a greater accent on searching for innovation rather than efficiency in order to ensure a continuous progress in the organization and to maintain business sustainability. The paper will not be comparing the efficiency of these different philosophies, or the results they generated, as time will still be the ultimate judge.

    Full Text Available In the present note, we present the main features of recent trends in vital family-demographic behavior in Sweden. For this purpose, published indices of marriage, divorce, and childbearing risks by calendar year are updated by adding another two or three years of observation to our series. We demonstrate that the latest trend reversal in Swedish birth rates, which occurred at the end of the 1990s, continued to manifest itself in increasing propensities for childbearing during the early years of the 21st century. The rise pertains to all birth orders. Marriage propensities showed an increase as well, however, to a large extent expressed in a short-term development that was prevalent at the turn of the millennium. The previous long-term trend of rising divorce risks leveled off during the first two years of the new century.

  4. Youth prolongation and identity: study of the processes of transition to adulthood in Brazilian and Spanish youngsters

    Directory of Open Access Journals (Sweden)

    Raquel Nascimento Coelho

    2014-06-01

    Full Text Available In this paper we investigate the relationship between youth prolongation in Brazilian and Spanish youngsters and the identity construction processes of these individuals. We conducted semi-structured interviews with 50 young men and women aged 25 to 29 years, half of them from Madrid/Spain and the other half from Fortaleza/Brazil. The interviews were recorded and transcribed, the speeches were organized with the Atlas-ti program through a semantic content analysis. We assume that the postponement of the thresholds of transition to adulthood leads to new experiences, discourses and meanings of "being young", creating a new ideal-typical model of "prolonged youth" and turning it into a possibility of identification for a significant group of young people. In Spain, the youth prolongation is a much more pronounced and evident phenomenon than in Brazil. However, the movement towards a youth prolongation, especially concerning the "feeling younger for longer" is also a trend among young Brazilians.

    The study aimed to estimate the prevalence, severity, and inequality in the distribution of dental caries in schoolchildren from Florianópolis, Santa Catarina, Brazil, in 2011, and to compare the results with data from previous studies carried out since 1971. All 12- and 13-year-old schoolchildren enrolled in a public school were eligible. Dental caries were assessed according to the World Health Organisation diagnostic criteria. Decayed, missing and filled surfaces and teeth (DMFS/DMFT) indexes, the Significant Caries Index (SiC) and the Gini coefficient (to assess inequalities in the distribution of dental caries) were estimated. The response rate was 82.3% (n = 130). The prevalence of dental caries decreased from 98.0% (95% CI 96.0-100.0) in 1971 to 36.9% (95% CI 28.5-45.3) in 2011. The mean DMFT ranged from 9.2 in 1971 to 0.7 in 2011. The mean DMFS index was 1.2 (95% CI 0.8-1.6) in 2011. The Gini coefficient was 0.624 in 2002 but increased to 0.725 in 2011; the Lorenz curve showed that 70-75% of dental caries attacks was restricted to 20% of the population in 2011. A reduction of 41.2% in the mean SiC index was observed between 2002 (3.4, 95% CI 3.0-3.8) and 2011 (1.9, 95% CI 1.6-2.1). An effective decline in the prevalence and severity of dental caries in schoolchildren was observed throughout 40 years of monitoring. However, a small proportion of the population has experienced most of the caries burden in the recent years studied.

    Brazil is a large country, with an evolving economy, but marked social inequalities. The population is formed by an admixture of native Brazilians, Europeans, and Africans; is predominantly urban; and faces rapid aging. Time trends related to health behaviors show a substantial reduction in smoking rates, but a rising prevalence of overweight and obesity, unhealthy eating habits, and insufficient physical activity. The high prevalence of hypertension and the increasing prevalence of diabetes mellitus are also causes for concern. Cardiovascular disease (CVD) has been the leading cause of mortality since the 1960s and has accounted for a substantial percentage of all hospitalizations. In 2011, CVD was responsible for 31% of all deaths, with ischemic heart disease (31%) and cerebrovascular diseases (30%) being the leading CVD causes. Despite an increase in the overall number of CVD deaths, the age-adjusted mortality rates for CVD declined 24% between 2000 and 2011. Health care delivered by Brazil's universal public health system, which focuses on primary prevention, has contributed to this achievement. However, the decline in age-adjusted mortality differs according to race, sex, and socioeconomic status with black individuals and lower-income populations sustaining the greatest impact of CVD, especially at younger ages. With one of the world's largest public health systems in terms of population coverage, Brazil has the means to implement actions to confront the high burden of CVD, focusing on health promotion and comprehensive care. Insufficient funding, low education levels, and social inequalities remain as the main barriers to be overcome. PMID:26811272

    In order to improve radiation protection it is necessary to have knowledge of the occupational radiation dose levels in all radiation facilities. This information comes from individual monitoring services, which are responsible for measuring and providing information about workers' radiation exposure. In 1981, the Comissao Nacional de Energia Nuclear (CNEN) of Brazil starts to develop a comprehensive system for regulation and storage of occupational radiation dose. This paper starts with an overview of the evolution of the Brazilian authorization and data storage system for external individual monitoring. It starts with a rule for authorization of all Brazilian photon individual monitoring services and the obligation for them to send the measured dose to CNEN. Up to now there is no regulation for neutron individual monitoring. The aim of this paper is to present the current scenario of the Brazilian external monitoring system, reinforcing its importance and remaining problems. The number of monitored workers greatly increases every year, having surpassed 150,000 people monitored. The stored data show that the mean annual occupational external dose is decreasing from 2.4 mSv in 1987 to about 0.6 mSv, in 2012, but there is still some not realistic very high dose measured (higher than 100 mSv), without investigation. About 80% of the annual dose values are lower than the monthly register level. As expected, the higher real photon doses are found in Nuclear Medicine, Industrial Radiology and Interventional Radiology. All recorded annual neutron dose values are lower than 20 mSv. (author)

    1998-01-01

    The general purpose of this research was to use recent satellite-based estimates of deforestation in Brazilian Amazonia to calculate the net flux of carbon associated with deforestation and subsequent regrowth of secondary forests. We have made such a calculation, in the process comparing two estimates of deforestation and two estimates of biomass for the region. Both estimates were based on the RADAMBRASIL survey. They differed in the equations used to convert wood-volumes to total biomass. The net flux of carbon from changes in land use seems to vary from year to year, perhaps by as much as a factor of 4.

    Full Text Available This paper relies on some data to identify the 19th century as the major period in which Brazil economy lagged behind some chosen benchmarking countries, as the USA, Canada, New Zealand, Australia and some European periphery countries. To identify the reasons for this an exercise using immigration data was used to make a decomposition of the sources of growth of the proportion of the USA per capita GDP to the Brazilian one. The results indicate that the imported human capital was responsible for 59% to 88% of this total growth between 1820 and 1900.

    Brazilian keratin treatments are widely available products that are used by women all over the world to straighten hair. Marketers of these products claim that the keratin treatments render naturally curly hair more manageable and frizz-free while enhancing color and shine, giving the hair a healthier appearance. Although widely used, there have been virtually no reports of adverse side effects. Unfortunately, many of the products that are applied by salon professionals contain formaldehyde or its derivatives and are being marketed as safe. PMID:23725308

    Full Text Available To investigate the hypothesis that the change from the female predominance of diabetes mellitus to a standard of equality or even male preponderance can already be observed in Brazilian mortality statistics.Data on deaths for which diabetes mellitus was listed as the underlying cause were obtained from the Brazilian Mortality Information System for the years 1980 to 2012. The mortality data were also analyzed according to the multiple causes of death approach from 2001 to 2012. The population data came from the Brazilian Institute of Geography and Statistics. The mortality rates were standardized to the world population. We used a log-linear joinpoint regression to evaluate trends in age-standardized mortality rates (ASMR.From 1980 to 2012, we found a marked increment in the diabetes ASMR among Brazilian men and a less sharp increase in the rate among women, with the latter period (2003-2012 showing a slight decrease among women, though it was not statistically significant.The results of this study suggest that diabetes mellitus in Brazil has changed from a pattern of higher mortality among women compared to men to equality or even male predominance.

    Full Text Available Driven by the growth of a global economy and developments in high technology, the process of creating and translating technical documentation has been evolving rapidly. In particular, machine translation (MT has shown increasing capabilities of efficaciously accomplishing the early stages of the eight stages of translation identified years ago by Robert Bly. As a consequence, translators have learned to use MT as a tool to accelerate their work, but they have also grown wary of MT’s potential for replacing them. To ensure steady employment, some translators have begun cross-training as technical writers; correspondingly, a few technical writers have begun cross-training as translators, as the two professions appear to be undergoing a gradual trend of convergence. Academic programs are urged to respond to the evolving trends.

    Vamos¸, C˘alin

    2013-01-01

    Our book introduces a method to evaluate the accuracy of trend estimation algorithms under conditions similar to those encountered in real time series processing. This method is based on Monte Carlo experiments with artificial time series numerically generated by an original algorithm. The second part of the book contains several automatic algorithms for trend estimation and time series partitioning. The source codes of the computer programs implementing these original automatic algorithms are given in the appendix and will be freely available on the web. The book contains clear statement of the conditions and the approximations under which the algorithms work, as well as the proper interpretation of their results. We illustrate the functioning of the analyzed algorithms by processing time series from astrophysics, finance, biophysics, and paleoclimatology. The numerical experiment method extensively used in our book is already in common use in computational and statistical physics.

    Thalita Amorim Vaz

    2012-10-01

    Full Text Available Because pension plans have been marketed using outdated technical premises, Brazilian insurance companies find themselves required to identify additional resources to ensure their ability to meet future benefit payments obligations. When calculating the additional amount of this provision, the parameters used are: mortality and disability decrements, the structure of interest rates, financial performance, cancellation fees and conversion rates. The aim of this study is to present the estimation of conversion rates based on a Probit Model. The data for this study was obtained through the transfer of restricted data from the portfolio of a company with relevant activity in the Brazilian insurance market, including a group of 14,511 individuals eligible for retirement in the period between January 1, 2005 and December 31, 2009. The resulting analysis of the data allows us to conclude that two factors — the volume of accumulated reserves and the classification of prices as actuarially fair —increase the propensity of an individual to convert resources upon retirement. In turn, retirement age and the need for liquidity reduce the propensity to convert resources upon retirement.

    Full Text Available Brands may be perceived as possessing a set of distinct traits or characteristics, i.e., a personality, similar to aperson. Thus, the personality of a brand is relevant as a source of differentiation in an increasingly competitivemarket environment. In this study, the authors explore the dimensions of brand personality proposed by J. Aaker(1997, seeking to discover the particular evaluation dimensions of the Brazilian context. The study wasconducted in exploratory stages, beginning with a preparatory stage that was carried out by professionals andacademics from the fields of communication and marketing. This was followed by stages of conclusive researchusing an online survey with a sample of 1,302 Brazilian consumers. Two sub-samples were extracted: onecalibration sample for exploratory factor analysis and a validation sample to perform confirmatory factoranalysis in order to verify the convergent and discriminant validities of the final scale. Five dimensions of brandpersonality in Brazil were detected: credibility, joy, audacity, sophistication and sensitivity. These dimensionsshowed some differences in comparison with similar studies that had been carried out in other countries. Thestudy led to a scale of 28 items for measuring brand personality and made it possible to compare competingbrands in terms of brand personality.

    Full Text Available Ochratoxin A is a nephrotoxic, teratogenic and imunotoxic compound produced by Aspergillus and Penicillium spp. It is a suspected carcinogen to humans and it is carcinogenic to rats. Recently it has drawn attention because it has been found in coffee and it has been the object of regulation by coffee importing countries. Brazil is the largest coffee producing country and its largest consumer. In order to conduct an initial assessment of the situation of the coffee produced in the country and offered to its population, one hundred and thirty two samples of Brazilian green coffee from 5 producing states (Minas Gerais, Paraná, São Paulo, Espírito Santo and Bahia and destined for the home market, were collected at sales points at the cities of Londrina and Santos, Brazil, and analyzed for ochratoxin A. The toxin was isolated in immunoaffinity columns and quantified by HPLC with florescence detection. The limit of detection was 0.7ng/g and the average RSD for duplicates of the samples was 11%. Twenty seven samples were found contaminated with the toxin and the average concentration for the contaminated samples was 7.1ng/g ochratoxin A. Neither the total number of defects nor the number of specific defects according to the Brazilian coffee classification system (black, partly -- black, sour, stinkers-black, stinkers-green, pod beans showed any relation to the contamination of the samples with ochratoxin A.

Admission of students with disabilities in the Brazilian schools was characterized by several phases: the welfarist phase, the integration phase and the inclusion phase, which is the most recent one and now being debated. The presence of a special device fosters the differences, even when everybody enters the classbecause a separation perspective damps down all the procedural and design efforts towards a true integration, holding back collaboration and action sharing among teachers. We consider however effective an action that accompanies the gradual learning evolution mediating between the student with disabilities and peers, between him and the teachers, between him and the learning tools designed.

    Full Text Available Leishmaniasis, an endemic parasitosis that leads to chronic cutaneous, mucocutaneous or visceral lesions, is part of those diseases, which still requires improved control tools. Propolis has shown activities against different bacteria, fungi, and parasites. In this study we investigated the effect of four ethanolic extracts of typified propolis collected in different Brazilian states, on Leishmania amazonensis performing assays with promastigote forms, extracellular amastigotes, and on infected peritoneal macrophages. Ethanolic extracts of all propolis samples (BRG, BRPG, BRP-1, and BRV were capable to reduce parasite load as monitored by the percentage of infected macrophages and the number of intracellular parasites. BRV sample called red propolis, collected in the state of Alagoas, and containing high concentration of prenylated and benzophenones compounds, was the most active extract against L. amazonensis. The anti-Leishmania effect of BRV sample was increased in a concentration and time dependent manner. BRV treatment proved to be non-toxic to macrophage cultures. Since BRV extract at the concentration of 25 µg/ml reduced the parasite load of macrophages while presented no direct toxic to promastigotes and extracellular amastigotes, it was suggested that constituents of propolis intensify the mechanism of macrophage activation leading to killing of L. amazonensis. Our results demonstrate, for the first time, that ethanolic extracts of Brazilian propolis reduce L. amazonensis infection in macrophages, and encourage further studies of this natural compound in animal models of leishmaniasis.

    Beans are a major source of dietary protein in Brazil. However, high losses due to insect infestation occur after each harvest. To combat these losses, radiation processing of beans offers promise as an alternative to chemical treatment, provided the nutritional quality of beans is not impaired by the radiation treatment. Conflicting results have been published about the effect of radiation on the biological value of legume proteins. Therefore, two varieties of Brazilian beans were studied: 1) Phaseolus vulgaris L., var. carioca and 2) Vigna unguiculata (L.) Walp, var. macacar. The beans were irradiated with doses of 0, 0.5, 1.0, 2.5, 5.0 and 10 kGy. Since irradiated beans will be consumed after appropriate storage, the beans under study were stored for 6 months at ambient temperature. Protein quality was measured by a biological assay employing the nitrogen balance approach in weanling rats. The animals were fed with optimally cooked beans, which were the only source of protein ({approx}10%). Nitrogen contents of legumes, diets, animal urine and faeces were determined by Kjeldahl analysis. The indices for apparent protein quality: net protein utilisation, digestibility and biological value were not influenced by irradiation. Thus, radiation treatment of Brazilian beans offers considerable promise as an effective insect disinfestation process, without impairing the biological quality of the valuable bean protein.

    Full Text Available This study attempts to identify the determinant factors of credit rating in Brazil. The relevance of this proposal is based on the importance of the subject as well as the uniqueness of the Brazilian market. As for originality, the great majority of previous studies regarding credit rating have been developed in the US, UK and Australia; therefore the effect on other markets is still unclear, especially in emerging markets, like Brazil. We’ve used a Generalized Estimating Equations (GEE model considering a panel structure with a categorical dependent variable (credit rating and ten independent variables: leverage, profitability, size, financial coverage, growth, liquidity, corporate governance, control, financial market performance and internationalization. The sample consisted of 153 rating observations during the period of 1997-2011 for a total of 49 public firms operating in the Brazilian Market. Results showed that leverage and internationalization are significant at the 1% level in explaining credit rating. Performance in the financial market was significant at a 5% level; profitability and growth were also statistically significant, but at a 10% significance level.

    Full Text Available Biodiversity is one of the most fundamental properties of Nature. It underpins the stability of ecosystems, provides vast bioresources for economic use, and has important cultural significance for many people. The Pampa biome, located in the southernmost state of Brazil, Rio Grande do Sul, illustrates the direct and indirect interdependence of humans and biodiversity. The Brazilian Pampa lies within the South Temperate Zone where grasslands scattered with shrubs and trees are the dominant vegetation. The soil, originating from sedimentary rocks, often has an extremely sandy texture that makes them fragile—highly prone to water and wind erosion. Human activities have converted or degraded many areas of this biome. In this review we discuss our state-of-the-art knowledge of the diversity and the major biological features of this regions and the cultural factors that have shaped it. Our aim is to contribute toward a better understanding of the current status of this special biome and to describe how the interaction between human activities and environment affects the region, highlighting the fragility of the Brazilian Pampa.

    In this work, a comprehensive phylogenetic study based on 600 base pair nucleotide and on putative 200 amino acid sequences of NS5 was carried out in order to establish genetic relationships among 15 strains of 10 Brazilian flaviviruses: Bussuquara, Cacipacore, dengue type 1, 2 and 4, Iguape, Ilheus, Rocio, Saint Louis encephalitis (SLE), and yellow fever. Phylogenetic trees were created by neighbor-joining and maximum parsimony methods. These trees showed Brazilian flaviviruses grouped into three main branches: yellow fever branch, dengue branch subdivided in types 1, 2 and 4 branches, and Japanese encephalitis virus (JEV) complex branch including SLE virus strains, Cacipacore, Iguape, Rocio, Ilheus and Bussuquara. Viruses transmitted by Aedes mosquitoes, such as dengue and urban yellow fever, that are also the only Flavivirus causing hemorrhagic fevers in Brazil, were grouped in the same cluster. Encephalitis associated viruses, transmitted by Culex mosquitoes such as JEV complex branch including SLE virus strains, Cacipacore, Iguape, Rocio, Ilheus and Bussuquara were also grouped in the same clade.

    Land use and land cover changes in the Brazilian Amazon have major implications for regional and even global carbon cycling. Cattle pasture represents the largest single use (about 70%) of this once-forested land in most of the region. The main objective of this study was to use a modelling approach to examine the dynamics of soil carbon when forest is converted to pasture in the Brazilian Amazon. We used data from eleven site- specific `forest to pasture' chronosequences with the Century Ecosystem Model and the Rothamsted Carbon Model. The Century and RothC models predicted that forest clearance and conversion to well managed pasture would cause an initial decline in soil C stocks (0-20 cm depth), followed by a slow rise to levels exceeding those under native forest. The only exception to this pattern was found for a chronosequence in Suia-Missu, which is under degraded pasture. Statistical tests were applied to determine levels of agreement between simulated soil organic carbon stocks and observed stocks for all the sites within the 11 chronosequences in the Brazilian Amazon. The models also provided reasonable estimates (coefficient of correlation = 0.8) of the microbial biomass C in the 0-10 cm soil layer for two chronosequences when compared with available measured data. The Century model adequately predicted the magnitude and the overall trend in 13C for the six chronosequences where measured 13C data were available. Our results suggest that modelling techniques can be successfully used for monitoring soil C stocks and changes, allowing both the identification of current patterns in the soil and the prediction of future conditions.

  1. Diasporic and Transnational Internationalization: The Case of Brazilian Martial Arts

    Full Text Available Brazilian diasporas overseas hasreceived little academic interest. Nevertheless, estimates suggest that around three million Brazilians currently live in other countries. The present study looks at a specific type of diaspora: small entrepreneurs from the Brazilian martial arts sector. The study adopts the case study method of research. The unit of analysis is comprised by the martial arts (capoeira and Brazilian jiu-jitsu. Data analysis used secondary and primary data from interviews. Cross-case analysis searched for similarities and differences in the internationalization processes of the two martial arts, using several analytical devices, such as chronologies, timelines, matrices, and pattern matching analysis. Evidences suggest that the concept of diasporic internationalization fits better capoeira than Brazilian jiu-jitsu. However, Brazilian jiu-jitsu shows an initial combination of diasporic and transnational characteristics, but more recently became fully transnational. Brazilian jiu-jitsu became a truly global business, formally organized and professionally managed. Capoeira, however, is still seen as non-commercial and as the preservation and practice of an ancient art. Such ethos, combined with the origin of its members in lower economic classes and their restricted access to capital turns internationalization into an often less profitable activity.

    Full Text Available http://dx.doi.org/10.5007/2175-7968.2013v1n31p119Jorge Amado (1912-2001 is the most translated Brazilian writer and the literary figure that has shaped the reception of Brazilian literature in the world.  He is credited with opening the international literary market to the post-dictatorship generation of Brazilian writers.  Yet Amado is also a controversial figure.  The debate around him is sparked by what some believe is sexual and ethnic stereotyping in his post-1958 works and the reinforcement of "paternalistic "racial views. His reception therefore is mixed. For his English-language readers, he is a fascinating source of exotic and titillating narratives about the vast, unknown country of Brazil, and for Brazilians he is either a "great ambassador of Brazilian culture around the world" or a faux populist who disguises sexist and racist attitudes behind charming prose. This paper will address Amado's literary career, his unique contributions to Brazilian letters, the challenges of translating his work, and his influence on the production of a new Brazilian literature for export

    Protected areas in tropical countries are managed under different governance regimes, the relative effectiveness of which in avoiding deforestation has been the subject of recent debates. Participants in these debates answer appeals for more strict protection with the argument that sustainable use areas and indigenous lands can balance deforestation pressures by leveraging local support to create and enforce protective regulations. Which protection strategy is more effective can also depend on (i) the level of deforestation pressures to which an area is exposed and (ii) the intensity of government enforcement. We examine this relationship empirically, using data from 292 protected areas in the Brazilian Amazon. We show that, for any given level of deforestation pressure, strictly protected areas consistently avoided more deforestation than sustainable use areas. Indigenous lands were particularly effective at avoiding deforestation in locations with high deforestation pressure. Findings were stable across two time periods featuring major shifts in the intensity of government enforcement. We also observed shifting trends in the location of protected areas, documenting that between 2000 and 2005 strictly protected areas were more likely to be established in high-pressure locations than in sustainable use areas and indigenous lands. Our findings confirm that all protection regimes helped reduce deforestation in the Brazilian Amazon.

    Examining dental students' profiles and perspectives contributes to discussions concerning dental education and practice. This study aimed, first, to investigate Brazilian dental students' reasons for pursuing dentistry as an occupation and, secondly, to consider the professional expectations of freshman students at a Brazilian public university over a fifteen-year period. A cross-sectional study was performed using data from a self-administered questionnaire to all first-year students enrolled in the 1993-95 and 2006-08 periods at the Federal University of Goias, Brazil (n=376). A total of 296 students responded (response rate=78.7 percent). Frequency analysis and chi-square tests were used to compare frequencies between the two time periods. Job conception was cited as the primary reason for pursuing dentistry, and the students considered oral health promotion and oral disease prevention as the primary purposes of dentistry. Most students intended to serve both high and low socioeconomic populations and both private and public practices after graduation. The majority cited an interest in specializing in clinical fields, orthodontics being the most frequent option. Significant trends included a greater interest in health promotion and public services and specializing in aesthetic dentistry and implantology in the 2006-08 period. This study revealed significant differences in the freshman students' motivations and professional perspectives over time. Personal views and concepts about profession are major influencing factors for choosing dentistry as a career. PMID:21205736

An O. volvulus mitogenome from the Brazilian Amazonia focus was obtained using a combination of high-throughput and Sanger sequencing technologies. Comparisons made between this mitochondrial genome and publicly available mitochondrial sequences identified 46 variant nucleotide positions and suggested that our Brazilian mitogenome is more closely related to Cameroon-origin mitochondria than West African-origin mitochondria. As well as providing insights into the origins of Latin American onchocerciasis, the Brazilian Amazonia focus mitogenome may also have value as an epidemiological resource.

    Full Text Available This paper offers additional insights on the relationship between interest rates and business cycles in Brazil. First, I document that Brazilian interest rates are very volatile, counter-cyclical and positively correlated with net exports, as observed in other emerging market economies. Next, I present a dynamic stochastic general equilibrium model in which firms face working capital constraints and labor supply is independent of consumption. This parsimonious model, appropriately calibrated to the Brazilian economy, predicts that interest rate shocks can explain about one third of output fluctuations and delivers business cycle regularities consistent with the Brazilian data.

    Bioethanol from sugarcane is increasingly seen as a sustainable alternative energy source. Besides having high photosynthetic efficiency, sugarcane is a perennial tropical grass crop that can re-grow up to five or more years after being planted. Brazil is the largest producer of sugarcane in the world and management practices commonly used in the country lead to lower rates of inorganic N fertilizer application than sugarcane grown elsewhere, or in comparison to other feedstocks such as corn. Therefore, Brazilian sugarcane ethanol potentially promotes greenhouse gas savings. For that reason, several recent studies have attempted to assess emissions of greenhouse gases (GHG) during sugarcane production in the tropics. However, estimates have been mainly based on models due to a general lack of field data. In this study, we present data from in situ experiments on emission of three GHG (CO2, N2O, and CH4) in sugarcane fields in Brazil. Emissions are provided for sugarcane in different phases of the crop life cycle and under different management practices. Our results show that the use of nitrogen fertilizer in sugarcane crops resulted in an emission factor for N2O similar to those predicted by IPCC (1%), ranging from 0.59% in ratoon cane to 1.11% in plant cane. However, when vinasse was applied in addition to mineralN fertilizer, emissions of GHG increased in comparison to those from the use of mineral N fertilizer alone. Emissions increased significantly when experiments mimicked the accumulation of cane trash on the soil surface with 14 tons ha-1and 21 tons ha-1, which emission factor were 1.89% and 3.03%, respectively. This study is representative of Brazilian sugarcane systems under specific conditions for key factors affecting GHG emissions from soils. Nevertheless, the data provided will improve estimates of GHG from Brazilian sugarcane, and efforts to assess sugarcane ethanol sustainability and energy balance.

    Full Text Available Problem statement: A review of the tourism history shows that tourism as an industry was virtually unknown in Malaysia until the late 1960s. Since then, it has developed and grown into a major industry, making an important contribution to the country's economy. By allocating substantial funds to the promotion of tourism and the provision of the necessary infrastructure, the government has played an important role in the impressive progress of the Malaysian tourism industry. One of the important factors which can attract tourists to Malaysia is the tourism price. Has the price of tourism decreased? To answer this question, it is necessary to obtain the equilibrium prices as well as the yearly trend for Malaysia during the sample period as it will be useful for analysis of the infrastructure situation of the tourism industry in this country. The purpose of the study is to identify equilibrium tourism price trends in Malaysian tourism market. Approach: We use hotel room as representative of tourism market. Quarterly data from 1995-2009 are used and a dynamic model of simultaneous equation is employed. Results: Based on the result during the period of 1995 until 2000, the growth rate of the equilibrium price was greater than consumer price index and producer price index. Conclusion: In the Malaysian tourism market, new infrastructure during this period had not been developed to keep pace with tourist arrivals.

    The objectives were to analyze trends in TV watching in Brazil and to identify the association between this habit and food consumption in the Brazilian adult population from 2006 to 2014. Data were obtained from the Surveillance System for Risk and Protective Factors for Chronic Illnesses Using a Telephone Survey (VIGITEL) for the years 2006 to 2014. The daily habit of watching TV and consumption of fruits, vegetables, beans, meat, milk, sodas, and/or sweetened beverages were analyzed over the period, and their association was investigated using regression models. The proportion of adults that reported watching more than three hours of TV per day did not vary significantly over the years, but these individuals showed declining consumption of healthy foods and increasing consumption of unhealthy foods. This situation was observed in both sexes and in all age and schooling brackets. The habit of watching TV is associated with unhealthy eating. PMID:27653195

    We evaluate the relationship of positive cases of rabies with the continuing expansion of livestock production, and analyse the trends of this zoonosis in human population in the state of Pará, Brazilian Amazon. The distribution of rabies cases was recorded between 1999 and 2004. Of 148 cases of rabies, 21% were in humans and 79% in non-human mammals. The rapid growth in livestock numbers seems to be associated with the increase of positive cases in bovine livestock transmitted by vampire bats. This idea is supported by positive and significant relationship of both events in time (p<0.01), but failed when spatial distribution among regions of the state was considered. However, rabies cases tend to occur toward the northeastern of the state of Pará, where rabies cases are proportionally five times greater than other mesoregions, suggesting that increased livestock production may influence the increase of this zoonosis.

However, rabies cases tend to occur toward the northeastern of the state of Pará, where rabies cases are proportionally five times greater than other mesoregions, suggesting that increased livestock production may influence the increase of this zoonosis.

    Full Text Available Schizophrenia is a severe psychotic disorder with recurrent relapse and functional impairment. It results from a poorly understood gene-environment interaction. The Taq1A polymorphism (located in the gene cluster NTAD is a likely candidate for schizophrenia. Its rs1800497 polymorphism was shown to be associated with DRD2 gene expression. Therefore the present work aims to investigate a possible association between schizophrenia and such polymorphism. The compared distribution of the alleles and genotypes of the studied polymorphism was investigated in a Brazilian sample of 235 patients and 834 controls. Genotypic frequencies were in Hardy-Weinberg equilibrium. There was a trend of allelic association between the Taq1A polymorphism (rs1800497 with schizophrenia in the studied sample. However no statistically differences were found between cases and controls when analyzed by gender or schizophrenia subtypes.

    The objectives were to analyze trends in TV watching in Brazil and to identify the association between this habit and food consumption in the Brazilian adult population from 2006 to 2014. Data were obtained from the Surveillance System for Risk and Protective Factors for Chronic Illnesses Using a Telephone Survey (VIGITEL) for the years 2006 to 2014. The daily habit of watching TV and consumption of fruits, vegetables, beans, meat, milk, sodas, and/or sweetened beverages were analyzed over the period, and their association was investigated using regression models. The proportion of adults that reported watching more than three hours of TV per day did not vary significantly over the years, but these individuals showed declining consumption of healthy foods and increasing consumption of unhealthy foods. This situation was observed in both sexes and in all age and schooling brackets. The habit of watching TV is associated with unhealthy eating.

  19. The multiplicity of Brazilian Social Psychology

    Mariana Prioli Cordeiro

    2014-02-01

    Full Text Available Brazilian Social Psychology has many definitions, theories and objects of study. In this essay, based on Actor-Network Theory, we argue that these are not different aspects or attributes of a single object, but elements that help to perform different versions of this object. They are, therefore, elements that make Social Psychologies different, although related to each other. They produce a multiple Social Psychology, which is more than one and, at the same time, less than many. In doing so, we strived to call attention to the possibility of ordinating and coordinating reality in different ways, of recognizing that there are multiple and diverse actants in a discipline and of making a Social Psychology that searches for complex connections that articulate humans and non-humans and perform multiple realities.

  20. μ-SRXRF characterization of Brazilian emeralds

    International Nuclear Information System (INIS)

    The aim of the present study is to characterize emeralds from different mines of Brazil by using Synchrotron Radiation X-ray Fluorescence Microanalysis (μ-SRXRF). The advantage of this technique is that we can analyze a homogeneous, inclusion free area of the stone with the microbeam to distinguish the elemental fingerprint according to the provenance of the emerald. A total of 47 samples belonging to 5 different Brazilian mines were studied in this work and 28 elements were identified. By means of Principal Component Analysis (PCA) it is possible to build different groups according to the provenance of the stones, which allows to assign samples of unknown origin to the according mine.

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume. Additional information about the meeting can be found at our website: http://www.sbfisica.org.br/~rtfnb/xxxvii-en Support and sponsorship came from brazilian national agencies: Conselho Nacional de Desenvolvimento Científico e Tecnoógico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Fundação de Amparo á Pesquisa do Estado de São Paulo (FAPESP); Fundação de Amparo á Pesquisa do Estado do Rio de Janeiro (FAPERJ); Sociedade Brasileira de Física (SBF) and Instituto de Física da Universidade de São Paulo (IFUSP).

    2012-01-01

    This work deals with a computational investigation on the small ballistic reentry Brazilian vehicle SARA (acronyms for SAt\\'elite de Reentrada Atmosf\\'erica). Hypersonic flows over the vehicle SARA at zero-degree angle of attack in a chemical equilibrium and thermal non-equilibrium are modeled by the Direct Simulation Monte Carlo (DSMC) method, which has become the main technique for studying complex multidimensional rarefied flows, and that properly accounts for the non-equilibrium aspects of the flows. The emphasis of this paper is to examine the behavior of the primary properties during the high altitude portion of SARA reentry. In this way, velocity, density, pressure and temperature field are investigated for altitudes of 100, 95, 90, 85 and 80 km. In addition, comparisons based on geometry are made between axisymmetric and planar two-dimensional configurations. Some significant differences between these configurations were noted on the flowfield structure in the reentry trajectory. The analysis showed t...

    Full Text Available Five out of the seven recognized species of sea turtles (Testudines occur on the Brazilian coast. The Barcode Initiative is an effort to undertake a molecular inventory of Earth biodiversity. Cytochrome Oxidase c subunit I (COI molecular tags for sea turtle species have not yet been described. In this study, COI sequences for the five species of sea turtles that occur in Brazil were generated. These presented widely divergent haplotypes. All observed values were on the same range as those already described for other animal groups: the overall mean distance was 8.2%, the mean distance between families (Dermochelyidae and Cheloniidae 11.7%, the mean intraspecific divergence 0.34%, and the mean distance within Cheloniidae 6.4%, this being 19-fold higher than the mean divergence observed within species. We obtained species-specific COI barcode tags that can be used for identifying each of the marine turtle species studied.

    2013-12-01

    The objective of this study was to identify the motives for sport participation in a sample of young Brazilian athletes according to sex, age, and training history. A total of 1,517 participants (714 girls, 803 boys) ages 12 to 18 years were included in the study. The Portuguese version of the Participation Motivation Questionnaire was used to identify motives for sport participation. The most important motives were Skill Development and Fitness, whereas the least important were Fun and Achievement/Status. Sex, age, type of sport, onset of training, duration of training, training volume, and competitive experience significantly influenced the motives for sport participation reported by the athletes. These results will contribute to establish intervention programs designed to reduce sport dropout rates among young athletes.

    2014-01-01

    Full Text Available Corporate Social Responsibility practices have been on the rise in recent years in firms all over the world. Brazil, as one of the most important countries emerging on the international scene, is no exception to this, with more and more firms taking up these practices. The present study focuses on analyzing the corporate social responsibility practices that Brazilian companies engage into. The sample used is comprised of 500 firms grouped by geographical area; the theoretical framework is based on stakeholder and institutional theories; and the technique used for the analysis is the biplot, more specifically the HJ Biplot and cluster analysis. From the results obtained it is possible to infer that the CSR variables corresponding to environmental practices are more closely linked to companies located in the northern areas of Brazil. Social and community practices are related to companies primarily in the southern and northeastern regions of the country.

  12. Maintenance of Brazilian Biodiversity by germplasm bank

    2016-01-01

    Full Text Available Abstract: Currently the importance of using alternative strategies for biodiversity conservation is emphasized and since the establishment of germplasm bank is an alternative to the conservation of endangered species. This is a technique of great importance for the maintenance of Brazilian fauna. Since the early70'sthere was a growing concern about the need to preserve essential genetic resources for food and agriculture, mainly for conservation of genetic material from farm animals. Thus was created the Brasilia Zoo, in July 2010, the first Germplasm Bank of Wild Animals in Latin America, as an alternative strategy for the conservation of threatened or endangered species, using both gametes and somatic cells and stem cells. Then we argue to create new banks or research networks among different regions with aimed to tissue preservation.

    Results and discussion: Age at diagnosis was between 10 and 32 months and the severity of the disease correlated with the increasing of age at diagnosis. The predominant symptoms were vomiting, weight loss, and hepatomegaly. Severe renal tubular acidosis manifested in one child. All patients had remission of symptoms after dietary modification. The sequencing of the ALDOB gene identified one homozygous patient for the mutation c.524C>A (p.A175D, while the others were compound heterozygous for c.360_363delCAAA (p.N120KfsX32, c.178C>T (p.R60X mutations, c.448G>C (p.A150P and c.524C>A (p.A175D. Clinical improvement of patients after dietary treatment is suggestive of the diagnosis, confirmed by molecular analysis. The prevalence of mutations found in our Brazilian patients is different from those of international literature.

  14. Globalization and the Brazilian balance accounts

    International Nuclear Information System (INIS)

    The globalization of the world economy calls for a country specialization with new structures for the product sectors and an increase in the competitiveness in areas of specialization. This process requires the amplification of markets and the adoption of technological innovations which increase the volume of economic trade, but also change trade relations. This process is made possible because of price stabilization and the stability and transparency of the exchange rate policy of various countries. In this work it is shown the opportunity to place nuclear energy as one of the sectors in which Brazil may have competitive advantages and enhance its external balance accounts, by the competitive substitution of imports by producing internally goods and services which technology is known by Brazilian firms and because of the increase in exports.

    Sixteen extracts, obtained from eight Brazilian plants of Annonaceae family, were screened for their antibacterial activity: Xylopia frutescens, X. aromatica, X. amazonica, X. benthamii, Annona ambotay, A. crassiflora, A. muricata and A. cherimolia. Amongst the investigated extracts, six showed antibacterial activity against at least one of the tested organisms at the concentration of 100 microg/mL. The most active extracts were those prepared from X. frutescens, X. amazonica, and A. ambotay. A phytochemical screening showed the presence of anonaceus acetogenins in some active extracts. Eleven diterpenoids were also tested for comparison purposes. Six were natural products, previously isolated from Xylopia sp. (kaurenoic, frutoic, xylopic, 15beta-hydroxy-kaurenoic and trachylobanic acids plus kaurenol) and five were derivatives of such compounds, obtained by esterification or reduction reactions. Trachylobanic acid showed antibacterial activity against B. subtilis and S. aureus.

    2009-01-01

    Full Text Available The aim of this study was to evaluate methods for developing a Brazilian maize core collection. For an initial survey of the active collection, passport information, as well as characterization and evaluation of accessions, were taken into consideration, these then being divided according to geographic region and kernel-type. Multiple sampling methods were evaluated. The strategy of constant sampling generated extensive alterations in extract accession frequency. The multivariate strategy with dispersion graphs and principal components associated with the Tocher method was considered efficient for identifying the most divergent genotypes. The multivariate strategy generated greater alterations in the variance of traits. The average number of traits revealed few modifications with the various sampling strategies used. Therefore, the active collection could be considered as possessing a satisfactory amount of information for most of its accessions. Moreover, the multivariate strategy generated modifications in the variance of the traits, independent of sampling intensity.

    2016-01-01

    Power Grids and other delivery networks has been attracted some attention by the network literature last decades. Despite the Power Grids dynamics has been controlled by computer systems and human operators, the static features of this type of network can be studied and analyzed. The topology of the Brazilian Power Grid (BPG) was studied in this work. We obtained the spatial structure of the BPG from the ONS (electric systems national operator), consisting of high-voltage transmission lines, generating stations and substations. The local low-voltage substations and local power delivery as well the dynamic features of the network were neglected. We analyze the complex network of the BPG and identify the main topological information, such as the mean degree, the degree distribution, the network size and the clustering coefficient to caracterize the complex network. We also detected the critical locations on the network and, therefore, the more susceptible points to lead to a cascading failure and even to a blac...

    2012-05-01

    First Brasflux Workshop; Santa Maria, Rio Grande do Sul, Brazil, 14-15 November 2011 Last November, 33 researchers participated in a workshop to establish Brasflux, the Brazilian network of carbon flux stations, with the objective of integrating previous efforts and planning for the future. Among the participants were those leading ongoing flux observation projects and others planning to establish flux stations in the near future. International scientists also participated to share the experiences gained with other networks. The need to properly characterize terrestrial ecosystems for their roles in the global carbon, water, and energy budgets has motivated the implementation of hundreds of micrometeorological research sites throughout the world in recent years. The eddy covariance (EC) technique for turbulent flux determination is the preferred method to provide integral information on ecosystematmosphere exchanges. Integrating the observations regionally and globally has proven to be an effective approach to maximizing the usefulness of this technique for carbon cycle studies at multiple scales.

    2010-08-01

    Full Text Available Investigates the theme known as “Knowledge Management” (KM in three large Brazilian organizations trying to discuss its concepts, constituent elements, managerial approaches and tools, while aiming at leaving behind the purely terminological discussion, which is innocuous and naive. The basic presuppositions were two: (i most of what it´s referred to or named KM is actually “Information Management” (IM and IM is just one of the components of KM. KM is more than simply IM due to the fact that it includes and incorporates other concerns, such as the creation, use and sharing of information and knowledge in the organizational context; (ii a conceptual model or map can be formulated based on three basic conceptions: (a a strategic conception of information and knowledge, (b the introduction of such strategy in the tactical and operational levels through the several managerial approaches and informaion technology tools and (c the creation of an organizational space for knowledge. The main objective is to investigate and analyze the conceptions, motivations, practices and results of KM effectively implemented in three large Brazilian organizations. The qualitative research strategy used was the study of multiple cases with incorporated units of analysis and three criteria ere observed for the judgment of the quality of the research project: validity of the construct, external validity and reliability. Multiple sources of evidence were used and data analysis consisted of three flows of activities: data reduction, data displays and conclusion drawing/verification. The results confirmed the presuppositions and the fact that KM means a rethinking of management practices in the information ea. It was also identified that the main challenges facing organizations committed to KM have its focus on change management, cultural and behavioral issues and the creation of an enabling context that favors the creation, use and sharing of information and

  1. Global pharmacogenomics: distribution of CYP3A5 polymorphisms and phenotypes in the Brazilian population.

    Directory of Open Access Journals (Sweden)

    Guilherme Suarez-Kurtz

    Full Text Available The influence of self-reported "race/color", geographical origin and genetic ancestry on the distribution of three functional CYP3A5 polymorphisms, their imputed haplotypes and inferred phenotypes was examined in 909 healthy, adult Brazilians, self-identified as White, Brown or Black ("race/color" categories of the Brazilian census. The cohort was genotyped for CYP3A5*3 (rs776746, CYP3A5*6 (rs10264272 and CYP3A5*7 (rs41303343, CYP3A5 haplotypes were imputed and CYP3A5 metabolizer phenotypes were inferred according to the number of defective CYP3A5 alleles. Estimates of the individual proportions of Amerindian, African and European ancestry were available for the entire cohort. Multinomial log-linear regression models were applied to infer the statistical association between the distribution of CYP3A5 alleles, haplotypes and phenotypes (response variables, and self-reported Color, geographical region and ancestry (explanatory variables. We found that Color per se or in combination with geographical region associates significantly with the distribution of CYP3A5 variant alleles and CYP3A5 metabolizer phenotypes, whereas geographical region per se influences the frequency distribution of CYP3A5 variant alleles. The odds of having the default CYP3A5*3 allele and the poor metabolizer phenotype increases continuously with the increase of European ancestry and decrease of African ancestry. The opposite trend is observed in relation to CYP3A5*6, CYP3A5*7, the default CYP3A5*1 allele, and both the extensive and intermediate phenotypes. No significant effect of Amerindian ancestry on the distribution of CYP3A5 alleles or phenotypes was observed. In conclusion, this study strongly supports the notion that the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of pharmacogenomic studies, and dealt with as a continuous variable, rather than proportioned in arbitrary categories that do not capture the

    2015-09-01

    The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City) is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.

  10. Socioeconomic trends in radiology

    International Nuclear Information System (INIS)

    For radiology the socioeconomic environment is a topic of increasing importance. In addition to the well-known important scientific developments in radiology such as interventional MRI, several other major trends can be recognized: (1) changes in the delivery of health care, in which all kinds of managed care are developing and will influence the practice of radiology, and (2) the process of computerization and digitization. The socioeconomic environment of radiology will be transformed by the developments in managed care, teleradiology and the integration of information systems. If radiologists want to manage future radiology departments they must have an understanding of the changes in the fields of economics and politics that are taking place and that will increasingly influence radiology. Some important and recognizable aspects of these changes will be described here. (orig.)

  12. Temperature trend biases

    Venema, Victor; Lindau, Ralf

    2016-04-01

    In an accompanying talk we show that well-homogenized national dataset warm more than temperatures from global collections averaged over the region of common coverage. In this poster we want to present auxiliary work about possible biases in the raw observations and on how well relative statistical homogenization can remove trend biases. There are several possible causes of cooling biases, which have not been studied much. Siting could be an important factor. Urban stations tend to move away from the centre to better locations. Many stations started inside of urban areas and are nowadays more outside. Even for villages the temperature difference between the centre and edge can be 0.5°C. When a city station moves to an airport, which often happened around WWII, this takes the station (largely) out of the urban heat island. During the 20th century the Stevenson screen was established as the dominant thermometer screen. This screen protected the thermometer much better against radiation than earlier designs. Deficits of earlier measurement methods have artificially warmed the temperatures in the 19th century. Newer studies suggest we may have underestimated the size of this bias. Currently we are in a transition to Automatic Weather Stations. The net global effect of this transition is not clear at this moment. Irrigation on average decreases the 2m-temperature by about 1 degree centigrade. At the same time, irrigation has increased significantly during the last century. People preferentially live in irrigated areas and weather stations serve agriculture. Thus it is possible that there is a higher likelihood that weather stations are erected in irrigated areas than elsewhere. In this case irrigation could lead to a spurious cooling trend. In the Parallel Observations Science Team of the International Surface Temperature Initiative (ISTI-POST) we are studying influence of the introduction of Stevenson screens and Automatic Weather Stations using parallel measurements

  13. TRENDS IN ROMANIAN TOURISM

    2011-12-01

    Full Text Available Tourism is an industry of the future, having the potential to provide significant revenues, and an industry of 'beauty', because it will protect, preserve and contribute to arranging the environment affected by other human activities. This is why it is very important to know the evolution of this underdeveloped field in our country. This paper is intended as a study on current trends in Romanian tourism without any claim of being an exhaustive research on the industry, describing the main indices of tourist traffic and their influence on Romanian tourism. Nowadays, we witness three main trends in Romanian tourism: sustainability, ecotourism and the increasing presence of cultural tourism. Ecotourism, as a form of tourism, has emerged from people's need to withdraw in nature, to visit and learn about the natural areas which have or have not a national or international protection status. Cultural tourism appears as a type of tourism clearly differentiated from other forms or types of tourism, particularly through motivation. It can be defined as a form of tourist mobility whose primary goal is broadening the horizon of knowledge by uncovering its architectural and artistic heritage and the areas in which it originates. Sustainability for tourism, as for other industries, has three independent aspects: economic, socio-cultural and environmental. Sustainability implies permanence, which means that sustainable tourism requires the optimal use of resources, minimizing the negative economic, socio-cultural and ecological impact, maximizing the benefits upon local communities, national economies and conservation of nature. Regarding statistical data, in what quantity is concerned, there is an increase in Romanian tourism, but in what quality is concerned there is a setback for tourism in the last years. This aspect should make public authorities take concern in improving the infrastructure and the quality of the touristical activity and in diversifying

  14. Historic trends in manufacturing

    International Nuclear Information System (INIS)

    Manufacturing accounts for more of the world's energy use - around 40% of final energy - than any other major sector. In the OECD countries, its share of final energy use declined from about 35% to 30% between 1973 and 1988 due to rising consumption in other sectors and decline in manufacturing. It plays a more important role outside the OECD countries, however, accounting for approximately 40% of energy use in the Soviet Union, 60% in China, and 35-45% in other LDCs. At a global level, it is difficult to separate manufacturing from total industrial energy use, but trends in the latter give a reasonably good picture of those in manufacturing, since the latter dominates industrial activity and energy use. The other main industrial activities - mining and construction - account for 10-20% of total industrial energy use in the OECD countries, about 20% in the former East Bloc, and around 20-25% in the LDCs. Total OECD industrial energy use has fluctuated since the early 1970s, but was less in 1988 than in 1973. In the LDCs and former East Bloc, growth has been more steady, though the growth trend for the latter has levelled off since 1988. Decrease in the relative importance of energy-intensive industries within the manufacturing sector contributed to a decline in energy use in the OECD countries. Much more important, however, were decreases in the energy intensities of the various industry groups that comprise the sector. In the Former East Bloc, there seems to have been relatively little structural change or change in intensities. There is evidence that energy intensities have declined in a number of LDCs. 21 refs., 15 figs., 6 tabs

    Several initiatives have recently taken place in Brazil in order to foster the creation of centers dedicated to alternatives to animal testing. In 2008, Vanessa Sá-Rocha organized a meeting with Brazilian regulatory authorities and the major stakeholders in the field of testing to foster discussions on the process of funding, development, and validation of alternative methods in Brazil. Octavio Presgrave published a scientific article on "The Need for the Establishment of a Brazilian Centre for the Validation of Alternative Methods." Also in 2008, Jadir Nunes, together with Dermeval de Carvalho, prepared and presented a proposal to the Brazilian National Agency of Health Surveillance (ANVISA) for the creation of a Centre for the Validation of Alternative Methods. ECVAM and other European stakeholders have been involved in the initiatives. Furthermore, also in 2008, a new legislation has been adopted in Brazil regarding the use of animals for scientific purposes ("lei Arouca"). The legislation establishes, among other provisions, the task of monitoring and evaluating the introduction of alternative methods. However, the legislation does not provide for promotion of or information about, existing alternative methods to the larger Brazilian scientific community. In order to streamline the different activities, Chantra Eskes acted as a facilitator by establishing a new joint proposal with the current Brazilian stakeholders, aimed at setting up a Brazilian Center on Alternative Test Methods.

    ABSTRACT OBJECTIVE To determine the distribution of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides in Brazilian adolescents, as well as the prevalence of altered levels of such parameters. METHODS Data from the Study of Cardiovascular Risks in Adolescents (ERICA) were used. This is a country-wide, school-based cross-sectional study that evaluated 12 to 17-year old adolescents living in cities with over 100,000 inhabitants. The average and distribution of plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were evaluated. Dyslipidemia was determined by levels of total cholesterol ≥ 170 mg/dl, LDL cholesterol ≥ 130 mg/dl, HDL cholesterol < 45 mg/dL, or triglycerides ≥ 130 mg/dl. The data were analyzed by gender, age, and regions in Brazil. RESULTS We evaluated 38,069 adolescents – 59.9% of females, and 54.2% between 15 and 17 years. The average values found were: total cholesterol = 148.1 mg/dl (95%CI 147.1-149.1), HDL cholesterol = 47.3 mg/dl (95%CI 46.7-47.9), LDL cholesterol = 85.3 mg/dl (95%CI 84.5-86.1), and triglycerides = 77.8 mg/dl (95%CI 76.5-79.2). The female adolescents had higher average levels of total cholesterol, LDL cholesterol, and HDL cholesterol, without differences in the levels of triglycerides. We did not observe any significant differences between the average values among 12 to 14 and 15- to 17-year old adolescents. The most prevalent lipid alterations were low HDL cholesterol (46.8% [95%CI 44.8-48.9]), hypercholesterolemia (20.1% [95%CI 19.0-21.3]), and hypertriglyceridemia (7.8% [95%CI 7.1-8.6]). High LDL cholesterol was found in 3.5% (95%CI 3.2-4.0) of the adolescents. Prevalence of low HDL cholesterol was higher in Brazil’s North and Northeast regions. CONCLUSIONS A significant proportion of Brazilian adolescents has alterations in their plasma lipids. The high prevalence of low HDL cholesterol and hypertriglyceridemia, especially in Brazil’s North and Northeast regions

  2. Gamma radiation measurements in Brazilian commercial granites

    Full text of publication follows: Gamma radiation from radionuclides which are characterized by half lives comparable to the age of the earth, such as 40 K and the radionuclides from the 238 U and 232 Th series, and their decay products, represent the main terrestrial source of irradiation to the human body. Their concentrations vary for different types of rocks, where high radiation levels are associated with igneous rocks such as granite. Thorium, uranium and potassium concentrations of granitic rocks are intimately related to their mineral compositions and general petrologic features. Then, these features associated with effects of weathering and metamorphism produce expressive alterations in the relationship between the natural radionuclides (Th, U, K, Th/U and Th/K). Consequently, the measurements of thorium, uranium, and potassium concentrations of different granite samples result on individual differentiation sequences. From the 232 Th, 238 U and 40 K activity concentrations obtained for each sample, it is possible to evaluate their respective dose rates in air, when these stones are used as tiling rocks. These results are of great interest in the environmental radiological protection study, since granites are widely used as building and ornamental materials, including as indoor covering. In this way, the Laboratory of Radioecology (L.A.R.A.) of the Physics Institute of the Universidade Federal Fluminense (I.F. -U.F.F.) has been performing analyzes on more than one hundred differ ent types of the main Brazilian commercial granites in last two years [1]. Using NaI and HP Ge gamma-ray spectrometers to determine the concentration of natural radionuclides in these samples, the annual effective dose rates and the gamma activity concentration index have been evaluated and compared to the limits proposed by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and European Commission (E.C.). In addition, the correlations between thorium

METHODS Data from the Study of Cardiovascular Risks in Adolescents (ERICA) were used. This is a country-wide, school-based cross-sectional study that evaluated 12 to 17-year old adolescents living in cities with over 100,000 inhabitants. The average and distribution of plasma levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were evaluated. Dyslipidemia was determined by levels of total cholesterol ≥ 170 mg/dl, LDL cholesterol ≥ 130 mg/dl, HDL cholesterol < 45 mg/dL, or triglycerides ≥ 130 mg/dl. The data were analyzed by gender, age, and regions in Brazil. RESULTS We evaluated 38,069 adolescents - 59.9% of females, and 54.2% between 15 and 17 years. The average values found were: total cholesterol = 148.1 mg/dl (95%CI 147.1-149.1), HDL cholesterol = 47.3 mg/dl (95%CI 46.7-47.9), LDL cholesterol = 85.3 mg/dl (95%CI 84.5-86.1), and triglycerides = 77.8 mg/dl (95%CI 76.5-79.2). The female adolescents had higher average levels of total cholesterol, LDL cholesterol, and HDL cholesterol, without differences in the levels of triglycerides. We did not observe any significant differences between the average values among 12 to 14 and 15- to 17-year old adolescents. The most prevalent lipid alterations were low HDL cholesterol (46.8% [95%CI 44.8-48.9]), hypercholesterolemia (20.1% [95%CI 19.0-21.3]), and hypertriglyceridemia (7.8% [95%CI 7.1-8.6]). High LDL cholesterol was found in 3.5% (95%CI 3.2-4.0) of the adolescents. Prevalence of low HDL cholesterol was higher in Brazil's North and Northeast regions. CONCLUSIONS A significant proportion of Brazilian adolescents has alterations in their plasma lipids. The high prevalence of low HDL cholesterol and hypertriglyceridemia, especially in Brazil's North and Northeast regions, must be

    ABSTRACT OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined. It was also higher between students of private schools (15.9%; 95%CI 14.2-17.7) when compared to public ones (12.4%; 95%CI 11.4-13.4). It was higher in the Southeast region (14.5%; 95%CI 12.9-16.1), and in the city of Sao Paulo (16.7%; 95%CI 14.7-18.7). The lowest prevalence was observed in North region (9.7%; 95%CI 9.7-10.5), and in Teresina (6.3%; 95%CI 4.9-7.7). The prevalence of physician-diagnosed asthma was of 8.7% (95%CI 8.2-9.1); higher in the North region (13.5%; 95%CI 12.7-14.2), and in Porto Alegre (19.8%; 95%CI 17.5-22.3). It was lower in the Midwest (6.9%; 95%CI 6.0-7.8), and in Cuiaba (4.8%; 95%CI 3.8-5.9). We found no significant difference in the expression of this rate between the sexes, as well as in other variables evaluated by the study. CONCLUSIONS The prevalence of asthma in Brazilian adolescents is high. Rates of active asthma and physician-diagnosed asthma vary widely in different regions and capitals evaluated by the ERICA. These results may assist in the

    1995-11-01

    Changes wrought by environmental regulations in the way companies produce, develop, and deliver their products and services were discussed. Some `tell-tale` signs of a vacuum of industry leadership in environmental affairs were identified. These included: lack of a `visible` corporate environmental policy, role confusion, limited action in response to plans, process myopia, poorly utilized data, hidden accomplishments, and an adversarial relationship with the regulatory bodies. Key trends in environmental management, and the necessary attributes for effective environmental management expected of the next generation of industry leaders were briefly described, including (1) the incorporation of environmental plans into the core of the business process, and into corporate strategy; (2) the formation of business-led, line-driven, rather than staff driven plans; and (3) increased measurement and broad dissemination of environmental successes, and their incorporation into the company`s strategic leverage. The overwhelming importance of commitment at the highest level, and the value of a business-oriented approach over a functional approach for effective environmental management were stressed.

    Full Text Available Cloud computing has been a tremendous innovation, through which applications became available online, accessible through an Internet connection and using any computing device (computer, smartphone or tablet. According to one of the most recent studies conducted in 2012 by Everest Group and Cloud Connect, 57% of companies said they already use SaaS application (Software as a Service, and 38% reported using standard tools PaaS (Platform as a Service. However, in the most cases, the users of these solutions highlighted the fact that one of the main obstacles in the development of this technology is the fact that, in cloud, the application is not available without an Internet connection. The new challenge of the cloud system has become now the offline, specifically accessing SaaS applications without being connected to the Internet. This topic is directly related to user productivity within companies as productivity growth is one of the key promises of cloud computing system applications transformation. The aim of this paper is the presentation of some important aspects related to the offline cloud system and regulatory trends in the European Union (EU.

    Full Text Available As time passes by, it lets leak out newer methods, ideas and innovations. Robotic concepts have been traced back to about the 4th century, and today’s concepts have evolved even further, starting from tiny nanobots that could make their way into one’s blood stream, and moving onto giant robotic arms. Microrobotics has also been a major trend in today’s world. As we keep exploring as to how small circuits can actually get, it gives us a greater ability to focus on creating smaller microrobots. The purpose of this paper is to give an outline about the current advancements that have taken place specifically in microrobotics, and cover a variety of fields, including medical applications, insect behavior, microfabrication, micro assembly, positioning and also the microscale challenges that are faced with the fabrication and controlling of microrobots like the energy requirements and locomotion methods. Since the advancements in today’s generation of microrobotics is very rapid, such that a massive amount of ideas have been conceived in a matter of a decade, only a small number of recent ones have been chosen to be a part of this journal.

    The Idaho National Laboratory (INL) in collaboration with the U.S. Geological Survey (USGS) with the assistance of the Empresa de Pesquisa Energetica (EPE) and the Agencia Nacional de Energia Electrica (ANEEL) has performed a comprehensive assessment of the hydropower potential of all Brazilian natural streams. The methodology by which the assessment was performed is described. The results of the assessment are presented including an estimate of the hydropower potential for all of Brazil, and the spatial distribution of hydropower potential thus providing results on a state by state basis. The assessment results have been incorporated into a geographic information system (GIS) application for the Internet called the Virtual Hydropower Prospector do Brasil. VHP do Brasil displays potential hydropower sites on a map of Brazil in the context of topography and hydrography, existing power and transportation infrastructure, populated places and political boundaries, and land use. The features of the application, which includes tools for finding and selecting potential hydropower sites and other features and displaying their attributes, is fully described.

  10. REPRESENTATION OF DIFFERENCES IN BRAZILIAN JOURNALISTIC DISCOURSE

    2011-02-01

    Full Text Available Considering the technological advance, which enhances the
    production of mediatic discourses, and the notion of a libidinal power installed in our globalized societies, reflecting upon representation of differences seems to be a major issue. This essay discusses the production of journalistic discourses from an epistemological perspective. The field of media is taken as constituted by a triple component – discourse/narrative/machines – and we suggest that this triad has proved to be incomplete: discourse and narrative, once they really are vertexes of the triangle, are absences. Two journalistic-documentary productions – which intend to represent life in the slums of Brazil – are compared in order to reflect upon representation of differences in Brazilian journalistic discourse. In view of the up-to-date polarization and pulverization of discourses, we suggest that in the perspective of the journalistic discourse, one can only speak about alterity if one tries to comprehend the ways news is staged.

    The widespread use of pesticides in agriculture can lead to water contamination and cause adverse effects on non-target organisms. Brazil has been the world's top pesticide market consumer since 2008, with 381 approved pesticides for crop use. This study provides a comprehensive literature review on the occurrence of pesticide residues in Brazilian freshwaters. We searched for information in official agency records and peer-reviewed scientific literature. Risk quotients were calculated to assess the potential risk posed to aquatic life by the individual pesticides based on their levels of water contamination. Studies about the occurrence of pesticides in freshwaters in Brazil are scarce and concentrated in few sampling sites in 5 of the 27 states. Herbicides (21) accounted for the majority of the substances investigated, followed by fungicides (11), insecticides (10) and plant growth regulators (1). Insecticides are the class of major concern. Brazil would benefit from the implementation of a nationwide pesticide freshwater monitoring program to support preventive, remediation and enforcement actions.

    The rôle of astronomy in the Brazilian cultural diversity -though little known world- has been enormous. Thus, the different forms of popular music and erudite, find musical compositions and lyrics inspired by the stars, the eclipses in rare phenomena such as the transit of Venus in front of the sun in 1882, the appearance of Halley's Comet in 1910, in the Big Bang theory. Even in the carnival parades of the blocks at the beginning of the century astronomy was present. More recently, the parade of 1997, the samba school Unidos do Viradouro, under the direction of Joãozinho Trinta, offered a new picture of the first moments of the creation of the universe to join in the white and dark in the components of their school, the idea of matter and anti-matter that reigned in the early moments of the creation of the universe in an explosion of joy. Examples in classical music include Dawn of Carlos Gomes and Carta Celeste by Almeida Prado. Unlike The Planets by Gustav Holst -who between 1914 and 1916 composed a symphonical tribute to the solar system based on astrology- Almeida Prado composed a symphony that is not limited to the world of planets, penetrating the deep cosmos of galaxies.

    Full Text Available Most of the recent astonishing export growth in Brazil came from firms which already exported. The export base was not able to grow at the same pace. Since expanding the export base may have several positive effects on firms' productivity and size, in this paper we provide a four-level classification of Brazilian industrial firms according to their potential to export, and we identify a subset of non-exporting firms which are potential exporters. The effects of export stimulating policies may be improved by focusing more closely on these firms.O recente crescimento das exportações no Brasil se baseou fortemente naquelas firmas já exportadoras, e a base exportadora não conseguiu acompanhar o mesmo ritmo de crescimento. Considerando que expandir a base exportadora pode ter efeitos positivos sobre a produtividade e tamanho das firmas, neste artigo classificamos as firmas industriais brasileiras em quatro níveis de acordo com o potencial exportador, e especialmente identificamos um subconjunto de firmas que não exportam mas que são potenciais exportadoras. Os efeitos das políticas de promoção às exportações podem ser maximizados se elas forem focalizadas nestas firmas.

    Full Text Available BRCA1 mutations are known to be responsible for the majority of hereditary breast and ovarian cancers in women with early onset and a family history of the disease. In this paper we present a mutational survey conducted in 47 Brazilian patients with breast/ovarian cancer, selected based on age at diagnosis, family history, tumor laterality, and presence of breast cancer in male patients. All 22 coding exons and intron-exon junctions were sequenced. Constitutional mutations were found in seven families, consisting of one insertion (insC5382 in exon 20 (four patients, one four base-pair deletion (3450-3453delCAAG in exon 11 resulting in a premature stop codon (one patient, one transition (IVS17+2T> C in intron 17 affecting a mRNA splicing site (one patient, and a C> T transition resulting in a stop-codon (Q1135X in exon 11 (one patient. The identification of these mutations which are associated to hereditary breast and ovarian cancers will contribute to the characterization of the mutational spectrum of BRCA1 and to the improvement of genetic counseling for familial breast/ovarian cancer patients in Brazil.

    Full Text Available Sleep behavior patterns in childhood are influenced by familial, cultural and environmental factors. In understanding sleep in Native Brazilian Bororo children, one should consider the influence of their culture on the child's sleep. This research analyzes sleep habits of Native Bororo children from the Meruri village, located in an Indian Reservation in the state of Mato Grosso. Fourty four children ( 24 M; 20 F were evaluated; ages ranged from one month to 10 years, with a mean age of 4.9 years. Sleep characteristics were assessed by means of a standard questionnaire applied to the mothers. Cosleeping - sleeping together with family members - was a remarkable finding, in every child 0-2 year old and in 81.5% in the 2-10 years group. The second characteristic was sleeping with many people in the same room. There was an average of 5.1 people per room in the younger group and 3.9 people in the older group

    2015-04-01

    Full Text Available The exuberance of Brazilian flora has caused admiration since the arrival of the first navigators. Fifteen to twenty percent of plant species estimated for the planet are found in this country. Plant genetic resources are part of biodiversity with potential for use by human populations, and are linked to the culture of the people, establishing the traditional use or enabling an innovative use. In Brazil, the landscape architect Roberto Burle Marx was a pioneer in collecting, using, valuing and preserving native species that have been admired since the 16th century, although they were neglected in the following centuries due to the valuation of ornamental plants from Europe. Between 1930 and 1960, he carried out landscaping projects that became emblematic for the development of landscaping in the 20th century. The analysis of the trajectory of the landscape architect, the 22 projects he carried out during that period, as well as the genebank structured by him, reveal significant numbers in terms of conservation.

    2012-10-01

    Full Text Available This paper analyzes the phenomenon known as accrual anomaly in Brazil. In particular, we examine two hypotheses: (a that the earnings expectation included in the stock price fails to reflect the difference in persistence of the earnings components (accruals and cash flows; and (b that the construction of a hedge portfolio by taking a long (short position in assets with low (high accruals generates consistently abnormal returns. The data set includes nonfinancial firms listed on the BM&FBOVESPA between 1990 and 2008. The empirical tests required conducting panel data regressions to identify the persistence of earnings and theircomponents; the Mishkin test to identify whether the market rationally prices earnings; and the composition of a zero-investment (hedge portfolio to analyze whether a trading strategy based on accruals consistently provides abnormal positive returns. The results indicate that the accrual component is not mispriced by the Brazilian market, and that a trading strategy based on accruals does not provide consistently positive returns. Although this evidence does not encourage arbitrage, the results are relevant from various perspectives. The methodology applied permitted identifying the quality of earnings and of their components, as well as association between the components of earnings and returns.

    Full Text Available The antileishmanial and immunomodulatory effects of propolis collected in Botucatu, São Paulo State, Brazil, were evaluated in Leishmania (Viannia braziliensis experimental infection. The antileishmanial effect of propolis on promastigote forms was verified by reducing growth and by promoting morphologic alterations observed by scanning electron microscopy. In in vitro immunomodulatory assays, macrophages were pretreated with propolis and then infected with L. (V. braziliensis. In vivo, supernatants from liver cells and peritoneal exudate of BALB/c mice pretreated with propolis and infected with Leishmania (107/mL promastigotes were collected, and TNF-α and IL-12 were measured by ELISA. Macrophages incubated with propolis showed a significant increase in interiorization and further killing of parasites. An increased TNF-α production was seen in mice pretreated with propolis, whereas IL-12 was downregulated during the infection. In conclusion, Brazilian propolis showed a direct action on the parasite and displayed immunomodulatory effects on murine macrophages, even though the parasite has been reported to affect the activation pathways of the cell. The observed effects could be associated with the presence of phenolic compounds (flavonoids, aromatic acids, and benzopyranes, di- and triterpenes, and essential oils found in our propolis sample.

    This article describes the configuration of the scientific field in Brazil, characterizing the scientific communities in every major area of knowledge in terms of installed capacity, ability to train new researchers, and capacity for academic production. Empirical data from several sources of information are used to characterize the different communities. Articulating the theoretical contributions of Pierre Bourdieu, Ludwik Fleck, and Thomas Kuhn, the following types of capital are analyzed for each community: social capital (scientific prestige), symbolic capital (dominant paradigm), political capital (leadership in S & T policy), and economic capital (resources). Scientific prestige is analyzed by taking into account the volume of production, activity index, citations, and other indicators. To characterize symbolic capital, the dominant paradigms that distinguish the natural sciences, the humanities, applied sciences, and technology development are analyzed theoretically. Political capital is measured by presidency in one of the main agencies in the S & T national system, and research resources and fellowships define the economic capital. The article discusses the composition of these different types of capital and their correspondence to structural capacities in various communities with the aim of describing the configuration of the Brazilian scientific field.

    2010-07-01

    The first prototype of a hybrid electric fuel cell bus developed with Brazilian technology is unveiled. It is a 12 m urban-type, low-floor, air-conditioned bus that possesses three doors, air suspension, 29 seats and reversible wheelchair site. The bus body was built based on a double-deck type monoblock vehicle that is able to sustain important load on its roof. This allowed positioning of the type 3 hydrogen tanks and the low weight traction batteries on the roof of the vehicles without dynamic stabilization problems. A novel hybrid energy configuration was designed in such a way that the low-power (77 kWe) fuel cell works on steady-state operation mode, not responding directly to the traction motor load demand. The rate of kinetic energy regeneration upon breaking was optimized by the use of an electric hybrid system with predominance of batteries and also by utilizing supercapacitors. The electric-electronic devices and the security control softwares for the auxiliary and traction systems were developed in-house. The innovative hybrid-electric traction system configuration led to the possibility to decrease the fuel cell power, with positive impact on weight and system volume reduction, as well as to significantly decrease the hydrogen consumption.

It has been seen as one of the important stages in the re-constitutionalization of the country, insofar as it establishes the submission of Armed Forces commanders to a civilian minister, and although some analysts have considered that such submission is actually achieved, we point here to the military resistance and insubordination to civil power that are the result of an authoritarian legacy. To the extent that the Ministry of Defense is unable to implement its own policies in which the military would be required to follow civilian guidance, this article concludes with considerations on the civil Defense Ministry's political and institutional fragility vis-a-vis military command. The latter has been able to retain high levels of decision making autonomy in its relationship to the Ministry and its structure.

    Full Text Available Background. High-quality clinical and genetic descriptions are crucial to improve knowledge of orofacial clefts and support specific healthcare polices. The objective of this study is to discuss the potential and perspectives of the Brazilian Database on Orofacial Clefts. Methods. From 2008 to 2010, clinical and familial information on 370 subjects was collected by geneticists in eight different services. Data was centrally processed using an international system for case classification and coding. Results. Cleft lip with cleft palate amounted to 198 (53.5%, cleft palate to 99 (26.8%, and cleft lip to 73 (19.7% cases. Parental consanguinity was present in 5.7% and familial history of cleft was present in 26.3% subjects. Rate of associated major plus minor defects was 48% and syndromic cases amounted to 25% of the samples. Conclusions. Overall results corroborate the literature. Adopted tools are user friendly and could be incorporated into routine patient care. The BDOC exemplifies a network for clinical and genetic research. The data may be useful to develop and improve personalized treatment, family planning, and healthcare policies. This experience should be of interest for geneticists, laboratory-based researchers, and clinicians entrusted with OC worldwide.

  9. DISPOSITION EFFECT AMONG BRAZILIAN EQUITY FUND MANAGERS

    2015-01-01

    Full Text Available The disposition effect predicts that investors tend to sell winning stocks too soon and ride losing stocks too long. Despite the wide range of research evidence about this issue, the reasons that lead investors to act this way are still subject to much controversy between rational and behavioral explanations. In this article, the main goal was to test two competing behavioral motivations to justify the disposition effect: prospect theory and mean reversion bias. To achieve it, an analysis of monthly transactions for a sample of 51 Brazilian equity funds from 2002 to 2008 was conducted and regression models with qualitative dependent variables were estimated in order to set the probability of a manager to realize a capital gain or loss as a function of the stock return. The results brought evidence that prospect theory seems to guide the decision-making process of the managers, but the hypothesis that the disposition effect is due to mean reversion bias could not be confirmed.

    Full Text Available This article aims to reflect on the territorial dimension has been addressed in the current Brazilian health policy. Provides an initial approximation of the theoretical discussion about the category territory and its implications for social policy. Then we analyze how this category was included in the principles and guidelines of the National Health System, deployed in key programs and normative instruments of health policy from 1990. It is concluded that: the territorial dimension was present from conception through SUS guideline regionalization of activities and services. In the main programs implemented in the 1990s, the territorial dimension had a character cutouts geographical and normative instruments gave centrality to the process of decentralization. However, from the 2000s, the regionalization strategy, pointing to the territorial perspective, gains greater significance. However, we still need to overcome the logic purely political-administrative and act so as to identify the real needs of the people, their potential, diversity and particularities, towards "used territory" referred to Milton Santos.

  11. Copepods and fishes in the Brazilian Amazon

    1998-06-01

    The Amazon basin comprises the largest river ecosystem in the world (7 million km 2) with annual high and low water peaks and a constant temperature near 29°C. Some 2000 fish species and 40 species of free-living copepods are known to occur in Amazonia. The free-living forms serve as food for most larval fishes and some adults, but they also transmit several parasites including representatives of the nematode family Camallanidae. About three dozen species of parasitic copepods have been described from the Brazilian Amazon. Females of Amazonian parasitic copepods are found on skin, gill filaments, gill rakers or within the nasal fossae. Parasitic copepods are found on fishes that are from a few millimeters long up to those over 2 m in length and they are usually quite host specific. All have body pigmentation in different patterns and colors (frequently blues, such as cerulean, cobalt, spectrum, smalt or campanula). It is suggested that the coloration serves to attract specific host fish. Copepods have evolved adaptations for attachment and feeding, especially in the second antennae and endopods. Examples of progenesis, phoresis and commensalism are shown. Some species produce pathology such as a tourniquet effect, hyperplasia, blood loss and anemia, and can kill fishes by limiting their respiration.

  12. Exploring professionalization among Brazilian oral health technicians

    2012-07-01

    Full Text Available Abstract Professional dental auxiliaries emerged in the early 20th century in the United States of America and quickly spread to Europe and other regions of the world. In Brazil, however, oral health technicians (OHTs, who occupy a similar role as dental hygienists, had a long journey before the occupation achieved legal recognition: Brazilian Law 11.889, which regulates this occupation in the country, was only enacted in 2008. The aim of this paper is to review the literature on the professionalization of OHTs, highlighting the triggering, limiting and conflicting aspects that exerted an influence on the historical progress of these professionals in Brazil. We have tested Abbott’s and Larson’s theory on professionalization, against the history of OHTs. A number of different dental corporative interests exerted an influence over professionalization, especially in discussions regarding the permissible activities of these professionals in the oral cavity of patients. With primary health care advances in Brazil, the importance of these professionals has once again come to the forefront. This seems to be a key point in the consolidation of OHTs in the area of human resources for health in Brazil.

    Objective To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. Methods All the references of articles published in 2011 by the journals Acta Ortopédica Brasileira, Coluna/Columna and Revista Brasileira de Ortopedia were evaluated to as certain how many of these came from Brazilian journals and how many from foreign journals. Results 3813 references distributed among 187 articles were analyzed. Out of this total, 306 (8.02%) were from Brazilian journals. There was no difference between the three journals analyzed. There were 76 articles (40.64%) without any citations of articles in Brazilian journals and only two articles (1%) cited more Brazilian articles than articles published elsewhere. Conclusion There is a need for Brazilian researchers to cite articles from Brazilian journals more often. PMID:26229879

    2013-01-01

    Propolis is a complex honeybee product with resinous aspect, containing plant exudates and beeswax. Their color, texture, and chemical composition vary, depending on the location of the hives and local flora. The most studied Brazilian propolis is the green (alecrim-do-campo) type, which contains mainly prenylated phenylpropanoids and caffeoylquinic acids. Other types of propolis are produced in Brazil, some with red color, others brown, grey, or black. The aim of the present work was to determine the chemical profiles of alcohol and chloroform extracts of eight samples of propolis, corresponding to six Brazilian regions. Methanol and chloroform extracts were obtained and analyzed by HPLC/DAD/ESI/MS and GC/MS. Two chemical profiles were recognized among the samples analyzed: (1) black Brazilian propolis, characterized chiefly by flavanones and glycosyl flavones, stemming from Picos (Piauí state) and Pirenópolis (Goiás state); (2) green Brazilian propolis, characterized by prenylated phenylpropanoids and caffeoylquinic acids, stemming from Cabo Verde (Bahia state), Lavras and Mira Bela (Minas Gerais state), Pariquera-Açu and Bauru (São Paulo state), and Ponta Grossa (Paraná state). The present work represents the first report of prenylated flavonoids in Brazilian propolis and schaftoside (apigenin-8-C-glucosyl-6-C-arabinose) in green propolis. PMID:23690840

    2016-01-01

    This paper presents an economic assessment of Brazilian agribusiness and its relationship with other economic sectors. It was found that, in 2011, agribusiness had a share of 18.45% (basic prices) and 19.77% (market prices) of Brazilian GDP. The tax burden of agribusiness (20.68%) was higher than that of other sectors (13.59%), despite agribusiness being a major contributor to the generation of foreign exchange, employment, and essential products, such as food. Brazilian agribusiness is a major employer, responsible for 29.39% of national employment. However, its average income is lower than in the other sectors of the Brazilian economy. Finally, agribusiness was found to be the biggest generator of foreign exchange, with a positive balance of trade. It was possible to conclude that agribusiness forms a strong link between agriculture and livestock, industry, and services in other economic sectors. For this reason, it can be said that the development of agribusiness is highly relevant to the process of Brazilian economic development and is therefore important to the progress of economic policies.

    Full Text Available OBJECTIVES: To identify the most cited articles in general surgery published by Brazilian authors. INTRODUCTION: There are several ways for the international community to recognize the quality of a scientific article. Although controversial, the most widely used and reliable methodology to identify the importance of an article is citation analysis. METHODS: A search using the Institute for Scientific Information citation database (Science Citation Index Expanded was performed to identify highly cited Brazilian papers published in twenty-six highly cited general surgery journals, selected based on their elevated impact factors, from 1970 to 2009. Further analysis was done on the 65 most-cited papers. RESULTS: We identified 1,713 Brazilian articles, from which nine papers emerged as classics (more than 100 citations received. For the Brazilian contributions, a total increase of about 21-fold was evident between 1970 and 2009. Although several topics were covered, articles covering trauma, oncology and organ transplantation were the most cited. The majority of classic studies were done with international cooperation. CONCLUSIONS: This study identified the most influential Brazilian articles published in internationally renowned general surgery journals.

    Brazilian scientists have been contributing to the protozoology field for more than 100 years with important discoveries of new species such as Trypanosoma cruzi and Leishmania spp. In this work, we used a Brazilian thesis database (Coordination for the Improvement of Higher Education Personnel) covering the period from 1987-2011 to identify researchers who contributed substantially to protozoology. We selected 248 advisors by filtering to obtain researchers who supervised at least 10 theses. Based on a computational analysis of the thesis databases, we found students who were supervised by these scientists. A computational procedure was developed to determine the advisors' scientific ancestors using the Lattes Platform. These analyses provided a list of 1,997 researchers who were inspected through Lattes CV examination and allowed the identification of the pioneers of Brazilian protozoology. Moreover, we investigated the areas in which researchers who earned PhDs in protozoology are now working. We found that 68.4% of them are still in protozoology, while 16.7% have migrated to other fields. We observed that support for protozoology by national or international agencies is clearly correlated with the increase of scientists in the field. Finally, we described the academic genealogy of Brazilian protozoology by formalising the "forest" of Brazilian scientists involved in the study of protozoa and their vectors over the past century.

    Full Text Available The objective of this study was to critically analyze the scientific production published in specialized Brazilian journals concerning the use of medicinal plants in dentistry. A literature review was carried out using an indirect documentation technique by means of a bibliographical study. Four examiners performed independent searches in Brazilian journals of medicinal plants indexed in the database SciELO (Brazilian Journal of Pharmacognosy; Brazilian Journal of Medicinal Plants; Brazilian Journal of Pharmaceutical Sciences; and Acta Botanica Brasilica using the descriptors "herbal medicine/phytotherapy" or "medicinal plants" and "dentistry ". The articles published from 2002 to 2012 addressing the use of medicinal plants in dentistry were included and analyzed. The searches based on the descriptors and reading of abstracts, resulted in 155 articles. Of these, 44 were read in full and a total of 16 publications met the eligibility criteria and were selected. Laboratory studies predominated (10 and were limited to the evaluation of antimicrobial properties by means of tests for determining inhibitory, fungicidal and bactericidal concentrations. Three literature reviews and only one clinical trial with no blinding and randomization were found. It is highlighted the need for better methodological designs in the researches and greater production of clinical or in vivo studies.

  9. The Corporate Governance of Privately Controlled Brazilian Firms

    2009-09-01

    Full Text Available We provide an overview of the corporate governance practices of Brazilian public companies, based primarily on an extensive 2005 survey of 116 companies. We focus on the 88 responding Brazilian private firms which are not majority owned by the state or a foreign company. We identify areas where Brazilian corporate governance is relatively strong and weak. Board independence is an area of weakness: The boards of most Brazilian private firms are comprised entirely or almost entirely of insiders or representatives of the controlling family or group. Many firms have zero independent directors. At the same time, minority shareholders have legal rights to representation on the boards of many firms, and this representation is reasonably common. Financial disclosure lags behind world standards. Only a minority of firms provide a statement of cash flows or consolidated financial statements. However, many provide English language financial statements, and an English language version of their website. Audit committees are uncommon, but many Brazilian firms use an alternate approach to ensuring financial statement accuracy – establishing a fiscal board. A minority of firms provide takeout rights to minority shareholders on a sale of control. Controlling shareholders often use shareholders agreements to ensure control.

    The Brazilian scientific production saw more than a four-fold increase from the 1990s onwards. The aim of this study was to evaluate the evolution of scientific production by Brazilian clinical neuroscientists over the last 10 years. A search in the PubMed identified 295 clinical neuroscientists and their publications. Brazilian production corresponded to 2.37% of the papers published by the 20 indexed periodicals that regularly publish clinical neuroscience research. If only the first and last two years are compared, there was a real growth of 75.1%. More than 40% of the Brazilian papers were published in Arquivos de Neuro-Psiquiatria, the official journal of the Brazilian Academy of Neurology. When only those periodicals with impact factor higher than one are considered, the percentage falls to 0.86% in the whole 10-year period, but attains 1.23% in 2004. Epilepsy and infectious diseases were the sub-areas with the highest scientific production.

This instrument was specifically created for measuring health service quality based on marketing and health care concepts. The aim of this study was to translate and culturally adapt the Health Service Quality Scale into Brazilian Portuguese and to assess the validity and reliability of the Brazilian Portuguese version of the instrument. Methods We conducted a cross-sectional, observational study, with public health system patients in a Brazilian university hospital. Validity was assessed using Pearson’s correlation coefficient to measure the strength of the association between the Brazilian Portuguese version of the instrument and the SERVQUAL scale. Internal consistency was evaluated using Cronbach’s alpha coefficient; the intraclass (ICC and Pearson’s correlation coefficients were used for test-retest reliability. Results One hundred and sixteen consecutive postoperative patients completed the questionnaire. Pearson’s correlation coefficient for validity was 0.20. Cronbach's alpha for the first and second administrations of the final version of the instrument were 0.982 and 0.986, respectively. For test-retest reliability, Pearson’s correlation coefficient was 0.89 and ICC was 0.90. Conclusions The culturally adapted, Brazilian Portuguese version of the Health Service Quality Scale is a valid and reliable instrument to measure health service quality.

    This report presents a description of the trends in growth of the elderly population in the Philippines and their health, disability, education, work status, income, and family support. The proportion of elderly in the Philippines is much smaller than in other Southeast Asian countries, such as Singapore and Malaysia. The elderly population aged over 65 years increased from 2.7% of total population in 1990 to 3.6% in 1990. The elderly are expected to comprise 7.7% of total population in 2025. The proportion of elderly is small due to the high fertility rate. Life expectancy averages 63.5 years. The aged dependency ratio will double from 5.5 elderly per 100 persons aged 15-64 years in 1990 to 10.5/100 in 2025. A 1984 ASEAN survey found that only 11% of elderly rated their health as bad. The 1990 Census reveals that 3.9% were disabled elderly. Most were deaf, blind, or orthopedically impaired. 16% of elderly in the ASEAN survey reported not seeing a doctor even when they needed to. 54% reported that a doctor was not visited due to the great expense. In 1980, 67% of men and 76% of women aged over 60 years had less than a primary education. The proportion with a secondary education in 2020 is expected to be about 33% for men and 33% for women. 66.5% of men and 28.5% of women aged over 60 years were in the formal labor force in 1990. Women were less likely to receive cash income from current jobs or pensions. 65% of earnings from older rural people was income from agricultural production. 60% of income among urban elderly was from children, and 23% was from pensions. Family support is provided to the elderly in the form of coresidence. In 1988, 68% of elderly aged over 60 years lived with at least one child. Retirement or nursing homes are uncommon. The Philippines Constitution states that families have a duty to care for elderly members.

  18. Towards a Brazilian radon map: consortium radon Brazil

    International Nuclear Information System (INIS)

    Recently, the idea of generating radon map of Brazil has emerged. First attempts of coordinating radon surveys-carried out by different groups across the country-and initial discussions on how to proceed on a larger scale were made at the First Brazilian Radon Seminary, Natal, September 2012. Conventionally, it is believed that indoor radon is no major problem in Brazil, because the overall benign climate usually allows high ventilation rates. Nevertheless, scattered measurements have shown that moderately high indoor radon concentrations (up to a few hundred Bq m-3) do occur regionally. Brazilian geology is very diverse and there are regions where an elevated geo-genic radon potential exists or is expected to exist. Therefore, a Brazilian Radon Survey is expected to be a challenge, although it appears an important issue, given the rising concern of the public about the quality of its environment. (authors)

    Full Text Available Foreign direct investment (FDI has become increasingly important for the Brazilian economy: the ratio of FDI inflow to the country's gross domestic product (GDP increased from a 0.6% average in the 1980's to 2.5% from 2001 to 2010, according to data from UNCTAD. However, there is great inequality in the distribution of this investment among Brazilian federation units. This study aims at investigating the determining factors for the location of foreign direct investment across Brazilian states, based on an econometric study with panel data for the years 1995, 2000 and 2005. The results showed that foreign investment responded positively to consumer market size, quality of labor and transport infrastructure, but negatively to cost of labor and tax burden.

  20. Systematic risk variations (beta convertible debenture brazilian companies

    2010-01-01

    Full Text Available purpose of this article is to analyze the impact of issuing convertible debentures on the systematic risk of Brazilian companies. Some applied researches in the U.S. capital market (STEIN, 1992; LEWIS et al, 2002; RAI, 2005 indicate that convertible debentures may be used as an alternative financing source when adverse selection problem makes stock issuing unattractive financing source. The analysis of Brazilian companies that issued convertible debentures recorded in the period from 1998 to 2006 and that presented liquidity on the market indicated that variation in beta, on average, is positive. These results are coherent with the signaling hypothesis and with the absence of convertible debenture issuing in 2005 and 2006 on the Brazilian market. They also may be related to the precarious financial situation of issuing companies, observed by the analysis of some financial indicators in year of issue and in two pre- e post-issuing years.

    Full Text Available The Brazilian party system presents a paradox. Although the Workers Party (PT and the Brazilian Social Democratic Party (PSDB have controlled presidential elections for the last 20 years, their force at the other levels of electoral competition has not grown. The objective of this study is to undertake a discussion of this situation through the 2014 general elections. After attempting to explain why successive challengers have not been able to change the structure of competition for the Brazilian presidency, I will analyze the relation established between the pattern observed at this level and the other “connected” electoral disputes—both those for state executive and federal legislative office. The general conclusion is that even if the pattern continues, it is quite improbable that this will significantly impact the other levels of national political party competition.

    Full Text Available In Brazil, many plants are used as tonic, fortifier, aphrodisiac, anti-stress, among other uses that are similar to the indications of an adaptogen. In general, such plants are used unspecifically, in situations of stress and fatigue, in the recovery after a previous pathological or debilitating state, or simply aiming at the maintenance of a healthy state. This article discusses the popular terms employed in the Brazilian folk medicine for the plants with this profile, their particularities and limitations. The article also discusses the possible mechanisms of action of an adaptogen and compares the main Brazilian plants used for that purpose: guarana (Paullinia cupana Kunth, family Sapindaceae, muirapuama (Ptychopetalum olacoides Benth., Olacaceae, catuaba (Anemopaegma arvense (Vell.

    2015-06-01

    Full Text Available From sustainability perspective, the supply chain management strategy can use different indicators related to Triple Bottom Line to improve its practices. Some studies in the topic have focused only environmental issues; however in some cases the social issues should be considered as a core of the sustainable strategies. Considering this view, the paper aims to highlight the relevance of social issues in the Brazilian context toward sustainable supply chain. Therefore, a theoretical essay was conducted using the literature about sustainable supply chain in relation to the Brazilian perspective to understand how it is possible to use new approaches for a more emphasis on social issues. The discussions indicates that to re-conceptualize the social relations in supply chains, it's necessary to use corporate social responsibility and social capital approaches to create a better discussion about sustainable supply chain. The proposal starts a discussion in the Brazilian context to stimulate new scholars to study this topic.

    2013-01-01

    The occupational health and safety conditions of a sample of Brazilian housecleaners in Massachusetts are examined in this article. We administered a main survey to a convenience sample of 626 Brazilian immigrant workers of all trades and a supplemental survey to 163 Brazilian housecleaners in Massachusetts in 2005 and 2006. Survey questions addressed housecleaner demographics, socioeconomic status, working conditions, and hazards of housecleaning work. Housecleaners are exposed to a variety of ergonomic, chemical, and biological hazards. Professional housecleaners' work is fast-paced, requires awkward postures, and involves repetitive movements, use of force, and heavy lifting. The most common symptoms reported include back pain, and pain in the muscles, arms, legs, neck, shoulder, hands, fingers, and feet. To reduce exposures to occupational hazards, we propose the substitution of green cleaners for toxic chemical cleaning products, the use of ergonomic equipment, the use of personal protective equipment, and changes in work organization.

  5. PERSPECTIVE: Learning from the Brazilian biofuel experience

    2006-11-01

    In the article `The ethanol program in Brazil' [1] José Goldemberg summarizes the key features of Brazil's sugarcane ethanol program—the most successful biofuel program in the world so far. In fact, as of 2005, Brazil was the world's largest producer of fuel ethanol. In addition to providing 40% of its gasoline market with ethanol, Brazil exports a significant amount of ethanol to Europe, Japan, and the United States. The success of the program is attributed to a variety of factors, including supportive governmental policies and favorable natural conditions (such as a tropical climate with abundant rainfall and high temperatures). As the article points out, in the early stages of the Brazilian ethanol program, the Brazilian government provided loans to sugarcane growers and ethanol producers (in most cases, they are the same people) to encourage sugarcane and ethanol production. Thereafter, ethanol prices were regulated to ensure that producers can economically sustain production and consumers can benefit from using ethanol. Over time, Brazil was able to achieve a price for ethanol that is lower than that for gasoline, on the basis of energy content. This lower cost is largely driving the widespread use of ethanol instead of gasoline by consumers in Brazil. In the United States, if owners of E85 flexible-fuel vehicles (FFVs) are expected to use E85 instead of gasoline in their FFVs, E85 will have to be priced competitively against gasoline on an energy-content basis. Compared with corn-based or sugar beet-based ethanol, Brazil's sugarcane-based ethanol yields considerably more favorable results in terms of energy balance and reductions in greenhouse gas emissions. These results are primarily due to (i) the dramatic increase of sugarcane yield in Brazil in the past 25 years and (ii) the use of bagasse instead of fossil fuels in ethanol plants to provide the heat needed for ethanol plant operations and to generate electricity for export to electric grids

    Background: A registry assessing the care of hypertensive patients in daily clinical practice in public and private centers in various Brazilian regions has not been conducted to date. Such analysis is important to elucidate the effectiveness of this care. Objective: To document the current clinical practice for the treatment of hypertension with identification of the profile of requested tests, type of administered treatment, level of blood pressure (BP) control, and adherence to treatment. Methods: National, observational, prospective, and multicenter study that will include patients older than 18 years with hypertension for at least 4 weeks, following up in public and private centers and after signing a consent form. The study will exclude patients undergoing dialysis, hospitalized in the previous 30 days, with class III or IV heart failure, pregnant or nursing, with severe liver disease, stroke or acute myocardial infarction in the past 30 days, or with diseases with a survival prognosis < 1 year. Evaluations will be performed at baseline and after 1 year of follow-up. The parameters that will be evaluated include anthropometric data, lifestyle habits, BP levels, lipid profile, metabolic syndrome, and adherence to treatment. The primary outcomes will be hospitalization due to hypertensive crisis, cardiocirculatory events, and cardiovascular death, while secondary outcomes will be hospitalization for heart failure and requirement of dialysis. A subgroup analysis of 15% of the sample will include noninvasive central pressure evaluation at baseline and study end. The estimated sample size is 3,000 individuals for a prevalence of 5%, sample error of 2%, and 95% confidence interval. Results: The results will be presented after the final evaluation, which will occur at the end of a 1-year follow-up. Conclusion: The analysis of this registry will improve the knowledge and optimize the treatment of hypertension in Brazil, as a way of modifying the prognosis of

    2015-04-01

    Full Text Available INTRODUCTION: aerobic fitness is considered one of the most important components of health-related physical fitness, with low levels related to increased risk of premature death from all causes, especially cardiovascular diseases. OBJECTIVE: to identify the characteristics of adolescents at higher risk of low levels of aerobic fitness. METHODS: the study included 696 adolescents 15-17 years of age enrolled in public high schools of Florianópolis, southern Brazil. This cross-sectional epidemiological study was conducted in Florianópolis, Santa Catarina, Brazil. Aerobic fitness was measured using the modified Canadian Aerobic Fitness Test mCAFT. Sociodemographic gender, age, school grade, paternal and maternal schooling, socioeconomic status, and anthropometric variables body weight, height, triceps and subscapular skinfold thickness, sexual maturation, physical activity, sedentary behavior, and eating habits were collected. RESULTS: it was found that 31.5% of adolescents had low aerobic fitness levels, being higher in boys 49.2% compared to girls 20.6%. Moreover, girls with sedentary behavior, overweight and high body fat percentage were the groups most likely to have inadequate aerobic fitness. In males, the groups most likely to have inadequate aerobic fitness were those whose parents studied more than eight years, those with low levels of physical activity, and those with inadequate nutrition and excessive body fat. CONCLUSION: low aerobic fitness levels were present in one third of adolescents and was more prevalent in boys. Lifestyle changes, including replacement of sedentary behaviors by physical and sport activities , may assist in improving the aerobic fitness of Brazilian adolescents.

  8. Neotectonics in the northern equatorial Brazilian margin

    2012-08-01

    An increasing volume of publications has addressed the role of tectonics in inland areas of northern Brazil during the Neogene and Quaternary, despite its location in a passive margin. Hence, northern South America plate in this time interval might have not been as passive as usually regarded. This proposal needs further support, particularly including field data. In this work, we applied an integrated approach to reveal tectonic structures in Miocene and late Quaternary strata in a coastal area of the Amazonas lowland. The investigation, undertaken in Marajó Island, mouth of the Amazonas River, consisted of shallow sub-surface geophysical data including vertical electric sounding and ground penetrating radar. These methods were combined with morphostructural analysis and sedimentological/stratigraphic data from shallow cores and a few outcrops. The results revealed two stratigraphic units, a lower one with Miocene age, and an upper one of Late Pleistocene-Holocene age. An abundance of faults and folds were recorded in the Miocene deposits and, to a minor extent, in overlying Late Pleistocene-Holocene strata. In addition to characterize these structures, we discuss their origin, considering three potential mechanisms: Andean tectonics, gravity tectonics related to sediment loading in the Amazon Fan, and rifting at the continental margin. Amongst these hypotheses, the most likely is that the faults and folds recorded in Marajó Island reflect tectonics associated with the history of continental rifting that gave rise to the South Atlantic Ocean. This study supports sediment deposition influenced by transpression and transtension associated with strike-slip divergence along the northern Equatorial Brazilian margin in the Miocene and Late Pleistocene-Holocene. This work records tectonic evidence only for the uppermost few ten of meters of this sedimentary succession. However, available geological data indicate a thickness of up to 6 km, which is remarkably thick for

  9. Stylized Facts in Brazilian Vote Distributions.

    Elections, specially in countries such as Brazil, with an electorate of the order of 100 million people, yield large-scale data-sets embodying valuable information on the dynamics through which individuals influence each other and make choices. In this work we perform an extensive analysis of data sets available for Brazilian proportional elections of legislators and city councilors throughout the period 1970-2014, which embraces two distinct political regimes: a military regime followed by a democratic one. We perform a comparative analysis of elections for legislative positions, in different states and years, through the distribution p(v) of the number of candidates receiving v votes. We show the impact of the different political regimes on the vote distributions. Although p(v) has a common shape, with a scaling behavior, quantitative details change over time and from one electorate to another. In order to interpret the observed features, we propose a multi-species model consisting in a system of nonlinear differential equations, with values of the parameters that reflect the heterogeneity of candidates. In its simplest setting, the model can not explain the cutoff, formed by the most voted candidates, whose success is determined mainly by their peculiar, intrinsic characteristics, such as previous publicity. However, the modeling allows to interpret the scaling of p(v), yielding a predictor of the degree of feedback in the interactions of the electorate. Knowledge of the feedback is relevant beyond the context of elections, since a similar interactivity may occur for other social contagion processes in the same population.

    Full Text Available This paper used a bibliometric research to compare and draw an overview of scientific production on forensic Accounting area, published in Brazilian journals in the period between 2005 and 2014 regarding the number of publications, characteristics of the authors, published topics, methodologies and its subclasses and and journals that publish in the area. It was collected and analyzed 48 articles the information as variation of year publication, subjects treated by, authors and their characteristics, Qualis classification, methodology, methodological nature applied, description of the empirical method and journals that have published articles in the area. Descriptive statistics were used to analyze the data. As a result it was found that the main subjects considered are related to the "work of the expert accountant", "expert opinion" and expertise within the context of judicial proceedings. Regarding the authors the vast majority produce only one article in the area over the 10 years examined, and these authors, 64,58% were male. The Qualis extract of the articles is located between C and B1, indicating that the publications fail to achieve high standards of academic quality. On the methodology it was found that 91.67% are empirical research, of these 78% ranked in quantitative or qualitative and 83% are publications opting for descriptive techniques. Regarding the journals, it was found that 50% have only one publication on "forensic accounting", indicating that it is not repeated exposure, as the number of publications ranging from two to five in the other 50% of journals. It is concluded that scientific research in forensic accounting area are still relatively embryonic, lacking certain softening related to the subjects, number of publications and quality of intellectual production.

    Determination of charcoal accumulation rate in lacustrine sediments allows to reconstruct the fire history of the region surrounding the lake. Our studies have been achieved in three Amazonian sites and one site in Atlantic rainforest. Charcoal fragments are identified and counted under a microscope. Typical size of these charcoals is around ten micrometers and they probably have been subject to eolian transport. The highest charcoal accumulation rates were obtained in sediments from Middle Holocene in Carajás region, eastern Amazonia. These rates are on the same order than the present day charcoal accumulation rate in Alta Floresta, a region of Amazonia which is being submited to intense slash and burn. The lowest values were found in Lagoa da Pata in Sao Gabriel da Cachoeira, a very humid area in western Amazon. We observed from the D. Helvécio record, in the Atlantic rainforest, fire occurrences from 8,400 to 6,400 cal years BP. For Carajás lake, surrounded by tropical rain forest, we had identified fires during the period between 8,000 and 5,300 cal years BP. Finally, the lake Caracarana, which is surrounded by grass savanna, showed a record of main fire occurrence phase at 9,750 cal yrs BP and a second phase marked by charcoal peaks at 7,680, 6,990 and 6,460 cal yrs BP. The synchronism of the fire occurrence periods in different Brazilian regions is related to the Middle Holocene dry climate phase provoked by the low summer insolation. Differences in the accumulation rates can be attributed to differences in biomass availability and fire return time. The carbon released in the atmosphere by this fires must have contributed to the observed increase of CO2, poorer in 13C, during the middle Holocene.

    Long-term temperature trends in lakes integrate hydrological and meteorological factors. We examine temperature trends in a small montane lake with prolonged ice-cover and large seasonal snowfall and in a large saline lake. Emerald Lake, located in the Sierra Nevada (California), is representative of high-elevation lakes throughout the region. No significant trend in outflow temperature was apparent from 1991to 2012. Snowfall in the watershed accounted for 93% of the variability in average summer lake temperatures. Mono Lake (California) lies in a closed, montane basin and is hypersaline and monomictic or meromictic. Temperature profiles have been collected from 1982 to 2010. In the upper water column, the July-August-September water temperatures increased 0.8-1.0°C over the 29 years. This rate of warming is less than published estimates based on satellite-derived skin temperatures and will discussed in the context of general limnological interpretation of temperature trends.

    This study aimed to describe trends in family spending on cigarettes and its share of family budget, comparing 2002 and 2009, using the Brazilian Household Budget Surveys from 2002/2003 and 2008/2009. The Expanded Consumer Price Index (IPCA) was used. The proportion of families that purchased cigarettes decreased from 23.5% to 18.2%, however their spending increased from BRL 55.36 to BRL 59.45. Spending on cigarettes was proportional to family income and head-of-family's schooling. Higher-income families still accounted for most of the expenditure, although the share of family income spent on cigarettes declined. The share of income for purchasing cigarettes was 5.2% in the lowest income quintile and 1.2% in the highest. Tobacco control policy has succeeded in reducing smoking prevalence in Brazil. However, economic measures are still important in the country, since the family's share of income and spending on cigarettes have decreased. PMID:26578014

As áreas de desova intensiva foram localizadas na parte sul da área de investigação, onde a ressurgência costeira foi menos freqüente. A intensidade de desova demonstrou uma variação anual relativamente grande. A produção total de ovos da sardinha- ­verdadeira variou de 99 bilhões de ovos durante o cruzeiro de janeiro de 1988 para 4669 bilhões de ovos em janeiro de 1981. O pico de desova ocorre na camada de mistura de superfície uma hora após a meia noite e os ovos eclodem em 19 horas com a temperatura de água 24 °e.

  6. Accounting greenhouse gas emissions in the lifecycle of Brazilian sugarcane bioethanol: Methodological references in European and American regulations

    International Nuclear Information System (INIS)

    This study discusses four European and American regulatory schemes designed for accounting lifecycle GHG emissions in relation to the Brazilian sugarcane ethanol. The objective is to critically examine the methodologies and associated parameters used in existing regulatory schemes for calculating GHG emissions, and to explore methodological convergences. The issues related to direct lifecycle and indirect land use change emissions have been addressed. It is found that there are commonalities between the European Renewable Energy Directive (EU-RED) and the UK's Renewable Transport Fuels Obligation (UK-RTFO), but the US-EPA's Renewable Fuel Standard (US-EPA) and the Low Carbon Fuel Standard of the California Air Resources Board (CA-CARB) vary greatly not only among themselves, but also in relation to the European regulations. Agricultural practices (especially soil carbon and nitrogen dynamics), co-product credits from surplus electricity and uncertainties around economic modeling approaches for indirect land use change are the major areas where methodological divergences exist. Incorporation of domestic agricultural practices, sugarcane mills operations, and realistic modeling of indirect impacts of land use change using regional models could provide more coherence in estimations of GHG emissions. Furthermore, the Brazilian trend of novelty in all phases of sugarcane bioenergy systems should be considered when projecting GHG emissions. - Highlights: ► This study analyses the methodological divergences for estimating GHG emissions. ► The lifecycle assessment of Brazilian sugarcane ethanol is examined. ► N2O emissions, co-product credits, and iLUC are the main factors on the divergences. ► GHG estimates of biofuels pathways needs further attention in regulatory schemes.

    In recent decades, we have observed an intensification of science, technology and innovation activities in Brazil. The increase in production of scientific papers indexed in international databases, however, has not been accompanied by an equivalent increase in the impact of publications. This paper presents a methodology for analyzing production and the impact of certain research areas in Brazil related to two aspects: the origin of the journals (national or foreign) and international collaboration. These two variables were selected for being of particular importance in understanding the context of scientific production and communication in countries with emerging economies. The sample consisted of papers written by Brazilian researchers in 19 subfields of knowledge published from 2002 to 2011, totaling 85,082 papers. To calculate the impact, we adopted a normalized indicator called the relative subfield citedness (Rw) using a window of 5 years to obtain measurements evaluated in 2 different years: 2007 and 2012. The data on papers and citations were collected from the Web of Science database. From the results, we note that most of the subfields have presented, from one quinquennium to another, improved performance in the world production rankings. Regarding publication in national and foreign journals, we observed a trend in the distribution maintenance of production of the subfields based on the origin of the journal. Specifically, for impact, we identified a lower Rw pattern for Brazilian papers when they were published in national journals in all subfields. When Brazilian products are published in foreign journals, we observed a higher impact for those papers, even surpassing the average global impact in some subfields. For international collaboration, we analyzed the percentage of participation of foreign researchers and the connection between collaboration and the impact of papers, especially emphasizing the distinction of hyperauthorship papers in terms of

    OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA), which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4) had smoked at least once in life, 5.7% (95%CI 5.3-6.2) smoked at the time of the research, and 2.5% (95%CI 2.2-2.8) smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge.

    Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance has increased the importance of discovering new therapeutic products. The present study aimed to investigate the in vitro leishmanicidal activity from 16 different Brazilian medicinal plants. Stationary-phase promastigotes of Leishmania amazonensis and murine macrophages were exposed to 44 plant extracts or fractions for 48 h at 37°C, in order to evaluate their antileishmanial activity and cytotoxicity, respectively. The most potent extracts against L. amazonensis were the hexanic extract of Dipteryx alata (IC50 of 0.08 μg/mL), the hexanic extract of Syzygium cumini (IC50 of 31.64 μg/mL), the ethanolic and hexanic extracts of leaves of Hymenaea courbaril (IC50 of 44.10 μg/mL and 35.84 μg/mL, respectively), the ethanolic extract of H. stignocarpa (IC50 of 4.69 μg/mL), the ethanolic extract of Jacaranda caroba (IC50 of 13.22 μg/mL), and the ethanolic extract of J. cuspidifolia leaves (IC50 of 10.96 μg/mL). Extracts of D. alata and J. cuspidifolia presented higher selectivity index, with high leishmanicidal activity and low cytotoxicity in the mammalian cells. The capacity in treated infected macrophages using the extracts and/or fractions of D. alata and J. cuspidifolia was also analyzed, and reductions of 95.80%, 98.31%, and 97.16%, respectively, in the parasite burden, were observed. No nitric oxide (NO) production could be observed in the treated macrophages, after stimulation with the extracts and/or fractions of D. alata and J. cuspidifolia, suggesting that the biological activity could be due to mechanisms other than macrophage activation mediated by NO production. Based on phytochemistry studies, the classes of compounds that could contribute to the observed activities are also discussed. In conclusion, the data presented in this study indicated that traditional medicinal plant extracts present effective antileishmanial activity. Future studies could focus on

  12. lon beam analysis of Brazilian coffee

    International Nuclear Information System (INIS)

    Full text: Coffee is one of the most popular and consumed beverages worldwide. Consumers can make the beverage from different types of coffee such as ground coffee, instant coffee or grinding roasted coffee beans. Each type of coffee leads to different characteristics in flavor and scent. The aim of this work is to perform an elemental analysis of ground coffee and roasted coffee beans. To that end, eight popular Brazilian ground coffee brands have been chosen to make a comparative study among brands. One of these brands was selected for a complete study of the beverage preparation process. This same brand offers packages of roasted coffee beans, which allowed the elemental comparison between ground coffee and roasted coffee beans. Roasted coffee beans were ground with a pestle and mortar. The beverage was prepared using a typical coffee pot. The spent and liquid coffees were submitted to a heat treatment and subsequently homogenized and pressed into pellets. The filters used in the coffee pot were analyzed as well. For micro-PIXE studies, coffee beans were cut in different parts for analysis. Samples of ground coffee and roasted coffee beans (grind) were analyzed by PIXE, while light elements like C, O and N were analyzed by RBS (Rutherford Backscattering Spectrometry). The roasted coffee beans were analyzed by micro-PIXE to check the elemental distribution in the beans. The elements found in powder coffee were Mg, AI, Si, P, S, CI, K, Ca, Ti, Mn, Fe, Cu, Zn and Rb. Potassium is the element with higher concentration, while Ti and Zn are trace elements. AI, Si and Ti showed the same concentration for all brands. Potassium and chlorine have high solubility, and about 80% of their concentration is transferred from the powder to the beverage during the infusion. Mg, P, CI, K, Mn, Fe, Zn and Rb showed significant variation between ground coffee and roasted coffee beans. The elemental maps show that potassium and phosphorus are correlated, and iron appears in particular

    Background Studies have questioned the downward trend in mortality from cardiovascular diseases (CVD) in Brazil in recent years. Objective to analyze recent trends in mortality from ischemic heart disease (IHD) and stroke in the Brazilian population. Methods Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. Risk of death was adjusted by the direct method, using as reference the world population of 2000. We analyzed trends in mortality from CVD, IHD and stroke in women and men in the periods of 1980-2006 and 2007-2012. Results there was a decrease in CVD mortality and stroke in women and men for both periods (p < 0.001). Annual mortality variations for periods 1980-2006 and 2007-2012 were, respectively: CVD (total): -1.5% and -0.8%; CVD men: -1.4% and -0.6%; CVD women: -1.7% and -1.0%; DIC (men): -1.1% and 0.1%; stroke (men): -1.7% and -1.4%; DIC (women): -1.5% and 0.4%; stroke (women): -2.0% and -1.9%. From 1980 to 2006, there was a decrease in IHD mortality in men and women (p < 0.001), but from 2007 to 2012, changes in IHD mortality were not significant in men [y = 151 + 0.04 (R2 = 0.02; p = 0.779)] and women [y = 88-0.54 (R2 = 0.24; p = 0.320). Conclusion Trend in mortality from IHD stopped falling in Brazil from 2007 to 2012. PMID:27223642

    2010-06-01

    Previous research shows that monolingual Japanese and Brazilian Portuguese listeners perceive illusory vowels (/u/ and /i/, respectively) within illegal sequences of consonants. Here, several populations of Japanese-Brazilian bilinguals are tested, using an explicit vowel identification task (experiment 1), and an implicit categorization and sequence recall task (experiment 2). Overall, second-generation immigrants, who first acquired Japanese at home and Brazilian during childhood (after age 4) showed a typical Brazilian pattern of result (and so did simultaneous bilinguals, who were exposed to both languages from birth on). In contrast, late bilinguals, who acquired their second language in adulthood, exhibited a pattern corresponding to their native language. In addition, an influence of the second language was observed in the explicit task of Exp. 1, but not in the implicit task used in Exp. 2, suggesting that second language experience affects mostly explicit or metalinguistic skills. These results are compared to other studies of phonological representations in adopted children or immigrants, and discussed in relation to the role of age of acquisition and sociolinguistic factors.

    A descriptive survey was performed in order to assess the statistical content and quality of Brazilian and international dental journals, and compare their evolution throughout the last decades. The authors identified the reporting and accuracy of statistical techniques in 1000 papers published from 1970 to 2000 in seven dental journals: three Brazilian (Brazilian Dental Journal, Revista de Odontologia da Universidade de Sao Paulo and Revista de Odontologia da UNESP) and four international journals (Journal of the American Dental Association, Journal of Dental Research, Caries Research and Journal of Periodontology). Papers were divided into two time periods: from 1970 to 1989, and from 1990 to 2000. A slight increase in the number of articles that presented some form of statistical technique was noticed for Brazilian journals (from 61.0 to 66.7%), whereas for international journals, a significant increase was observed (65.8 to 92.6%). In addition, a decrease in the number of statistical errors was verified. The most commonly used statistical tests as well as the most frequent errors found in dental journals were assessed. Hopefully, this investigation will encourage dental educators to better plan the teaching of biostatistics, and to improve the statistical quality of submitted manuscripts.

    Background Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. Results A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years.

    Full Text Available OBJECTIVE: This review of original reports on metabolic and infectious diseases that were recently published in Brazilian journals is designed to inform the readership of CLINICS about their content. METHODS: I conducted a search in PubMed for original research articles (clinical or basic research recently published (2008-2009 by Brazilian medical and biological periodicals. Papers on metabolic pathologies were retrieved by searching for appropriate keywords such as metabolic syndrome and obesity. Papers on infectious disease were obtained by entering 15 different keywords for the most commonly occurring pathologies. Review articles, editorials, letters to the editor, and case reports were manually excluded. Selected titles were then categorized into appropriate sub-categories. RESULTS: This search produced a total of 123 articles, which filtered down to 72 articles after eliminating editorials, review articles, letters to the Editor and case reports. Reviewed periodicals were Arquivos Brasileiros de Cardiologia, Arquivos Brasileiros de Endocrinologia e Metabologia, Brazilian Journal of Biological and Medical Research, Brazilian Journal of Infectious Diseases, Jornal de Pediatria, Jornal de Pneumologia, Revista da Associação Médica Brasileira, Revista da Escola de Enfermagem da Universidade de São Paulo, and São Paulo Medical Journal.

    Web-crawling approaches, that is, automated programs data mining the internet to obtain information about a particular process, have recently been proposed for monitoring early signs of ecosystem degradation or for establishing crop calendars. However, lack of a clear conceptual and methodological framework has prevented the development of such approaches within the field of conservation biology. Our objective was to illustrate how Google Trends, a freely accessible web-crawling engine, can be used to track changes in timing of biological processes, spatial distribution of invasive species, and level of public awareness about key conservation issues. Google Trends returns the number of internet searches that were made for a keyword in a given region of the world over a defined period. Using data retrieved online for 13 countries, we exemplify how Google Trends can be used to study the timing of biological processes, such as the seasonal recurrence of pollen release or mosquito outbreaks across a latitudinal gradient. We mapped the spatial extent of results from Google Trends for 5 invasive species in the United States and found geographic patterns in invasions that are consistent with their coarse-grained distribution at state levels. From 2004 through 2012, Google Trends showed that the level of public interest and awareness about conservation issues related to ecosystem services, biodiversity, and climate change increased, decreased, and followed both trends, respectively. Finally, to further the development of research approaches at the interface of conservation biology, collective knowledge, and environmental management, we developed an algorithm that allows the rapid retrieval of Google Trends data.

    The Revista Brasileira de Saúde Ocupacional (RBSO) - Brazilian Journal of Occupational Health - is an academic peer-reviewed journal in the field of Workers' Health that has been published by Fundacentro since 1973. Its historical trajectory, current performance, challenges and future perspectives were approached, in this paper, from a documental analysis. The journal's history can be divided into three periods, starting during the military government. At the beginning, the journal was the official vehicle for the Brazilian occupational accidents prevention policy, in which Fundacentro played a central role. The early 1980s opens space for technical-scientific publications and the field of Workers' Health emerges on the journal's pages. In 2005-6, a restructuring process is implemented, ensuring independent editorial policy and structures. Since 2006, 139 original papers and 9 thematic issues have been published. The journal is indexed in 9 bibliographic databases, has been ranked B1 in the field of interdisciplinary studies and B2 in the field of public health by CAPES, has an upward trend in the SciELO Impact Factor, and has an h-index of 5 in Google Scholar. Nevertheless, the low scientific production in the field and the high rate of rejection of manuscripts may jeopardize the survival of the journal, which is the main locus for scientific publications in the field of Workers' Health.

    Full Text Available The aim of this paper is to demonstrate the behavior of the ten largest Brazilian banks between June 2008 and September 2009, based on the analysis of financial indicators. Therefore, 16 three-monthly indices were calculated, extracted from financial statement information, which characterizes a documentary research. The indices were separated in five categories: liquidity, capital, profitability, income and market. The obtained results appointed that most financial institutions in the sample were able to manage their resources so as to gain conditions to maintain credit initially. Then, as from the first term of 2009, driven by public banks, they increased their credit operations. In addition, most banks revealed an anti-cyclical trend to encourage productive activities, preferably activities with higher liquidity levels, to the detriment of profitability, which reveals a more conservative attitude. Finally, it was verified that government initiatives, the Brazilian economic balance and the resources the banks offered helped to produce an environment to reactivate business activities during the most acute period of the subprime crisis.

    Full Text Available In the semi-strong form of the Efficient Markets Hypothesis - EMH, developed by Fama (1970, 1991, the prices reflect both the past and any information disclosed by companies, making impossible to an investor to get abnormal returns consistently, based on this type of information. In this paper we analyze the price behavior of common shares of 87 listed companies in the BM&FBovespa, in the announcements of 452 events of dividend distribution, occurred between January 2000 and September 2010, in order to identify the EMH in semi-strong form of Brazilian capital market. We used an event study, which evaluates abnormal returns of stocks relative to the market return (Ibovespa. The analysis of the abnormal return in the event window (10 days before and after the dividend distribution announcement showed an upward trend, with significant positive abnormal returns on days t-5, t-3, and t-1 to t+1. The results go in the direction of other studies of national literature and contribute to attest that the Brazilian capital market lacks the semi-strong form of informational efficiency.

    Full Text Available Brazil is the world's largest broiler meat exporter. Health control, knowledge and technology, as well as the natural aspects of the country are pointed out as the keys for the success of that product in the market. Brazilian broiler production grew significantly in the last decade; it creates jobs and has a significant social role in Brazilian economy. This study aimed at evaluating the Brazilian broiler meat supply chain from 2000 to 2010 using the social network analysis (SNA. Data from governmental and private sources were organized and analyzed. The focus of this study was the broiler production supply chain segment involving the hatchery, the broiler farm, the feed mill, the processing plant, and the government. The inputs considered were one-day-old chicks, pullet, feedstuff, and the infrastructure; and the outputs were broiler meat and taxes paid. The software UCINET was applied for calculating the structural attributes and indicators of the network. Results showed a relatively disorganized network in 2000 with the strongest tie between the farmer and the processing plant. The structural organization of the network improved until 2010. The density of the ties in the broiler meat production network increased steadily from 2000 to 2010 within a vertical cohesive supply chain structure. The success of Brazilian broiler meat production is attributed to the abundance of land, fertile soil, favorable climate, and the effort and investments in research and development by innovative companies in the last few years. The results of the present study showed that Brazilian broiler production evolved positively in the last ten years, and it was weakly influenced by international challenges.

    Full Text Available ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA. Food intake was estimated using 24-hour dietary recall (24-HDR. A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL. The Estimated Average Requirement (EAR method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years to 2,582 kcal (boy aged from14 to 17 years. Saturated fat and free sugar intake were above the maximum limit recommended ( 50.0%. Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar.

    Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining some requirements of the Brazilian Environmental Regulator (IBAMA). Besides this NPP, in the National Energy Program is previewed the installation of four more plants, by 2030. In November 2008, CNEN launched the Project RBMN (Repository for Low and Intermediate-Level Radioactive Wastes), which aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (authors)

    Full Text Available It has been suggested that one of the negative aspects of the New Economy has been growing organizational survival-risk both at the firm and the sector levels. This precarious positioning of the firm has profoundly changed the work environment resulting in the dissolution of job-definition-boundaries, thereby raising the intensity of work and finally affecting the level and nature of trust in the workplace. This is the starting point for our study. Using a questionnaire developed by Gillespie, we investigated gender profiles concerning trust in Supervisors, Peers, and Team in the New and the Old Economies for Brazilian managers. The results show that, for the New Economy, Brazilian women are more willing to give trust to Supervisors whereas Brazilian men expressed higher levels of trust when dealing with Team members. The Peer results are mixed. For the Old Economy, men uniformly express higher levels of trust compared to women over all three reference groups. Finally, for gender matched comparisons, those working in the Brazilian Old Economy firms express higher levels of trust compared to their counterparts in the New Economy independent of gender or time worked. We conclude by discussing the control implications of the above results.

    In being at the base of the marine food web, phytoplankton is particularly important for marine ecosystem functioning (e.g., biodiversity). Strong anthropization, over-exploitation of natural resources, and climate change affect the natural amount of phytoplankton and, therefore, represent a continuous threat to the biodiversity in marine waters. In particular, a concerning risks for coastal waters is the increase in nutrient inputs of terrestrial/anthropogenic origin that can lead to undesirable modifications of phytoplankton concentration (i.e., eutrophication). Monitoring chlorophyll (Chl) concentration, which is a proxy of phytoplankton biomass, is an efficient tool for recording and understanding the response of the marine ecosystem to human pressures and thus for detecting eutrophication. Here, we compute Chl trends over the Mediterranean Sea by using satellite data, also highlighting the fact that remote sensing may represent an efficient and reliable solution to synoptically control the “good environmental status” (i.e., the Marine Directive to achieve Good Environmental Status of EU marine waters by 2020) and to assess the application of international regulations and environmental directives. Our methodology includes the use of an ad hoc regional (i.e., Mediterranean) algorithm for Chl concentration retrieval, also accounting for the difference between offshore (i.e., Case I) and coastal (i.e., Case II) waters. We apply the Mann-Kendall test and the Sens’s method for trend estimation to the Chl concentration de-seasonalized monthly time series, as obtained from the X-11 technique. We also provide a preliminary analysis of some particular trends by evaluating their associated inter-annual variability. The high spatial resolution of our approach allows a clear identification of intense trends in those coastal waters that are affected by river outflows. We do not attempt to attribute the observed trends to specific anthropogenic events. However, the

    Brazilian social protection programs have had consistent effects in reducing poverty and inequality among their respective target-groups: children, adolescents and pregnant and breastfeeding women. In 2011, the Brazil without Extreme Poverty program was launched as a strategy to eradicate extreme poverty by 2014. It makes the promotion of rights the core concept of the official political narrative. This study seeks to provide a systematic description of the Brazil without Extreme Poverty program and its initial results. A review of official documents and academic studies on the social protection programs was conducted. The Brazil without Extreme Poverty program represents an incremental approach to the social protection policies enacted by the previous administration. It advocates a multidimensional and focused approach, funded primarily by the federal government. The strategy subscribes to the international trend of associating social protection with employment and income generation policies.

    Full Text Available Abstract Background Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health. Methods The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs. Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13 was used for the statistical analysis. P-values Results Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%, vitamin A (92.4% and vitamin C (85.1% in both genders. Intake variations were found between different regions, which may reflect cultural habits. Conclusion These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.

    The main objective of this doctoral thesis was to establish an improved design basis for offshore installations with respect to blowout risk analyses. The following sub objectives are defined: (1) Establish an offshore blowout database suitable for risk analyses, (2) Compare the blowout risk related to loss of lives with the total offshore risk and risk in other industries, (3) Analyse blowouts with respect to parameters that are important to describe and quantify blowout risk that has been experienced to be able to answer several questions such as under what operations have blowouts occurred, direct causes, frequency of occurrence etc., (4) Analyse blowouts with respect to trends. The research strategy applied includes elements from both survey strategy and case study strategy. The data are systematized in the form of a new database developed from the MARINTEK database. Most blowouts in the analysed period occurred during drilling operations. Shallow gas blowouts were more frequent than deep blowouts and workover blowouts occurred more often than deep development drilling blowouts. Relatively few blowouts occurred during completion, wireline and normal production activities. No significant trend in blowout occurrences as a function of time could be observed, except for completion blowouts that showed a significantly decreasing trend. But there were trends regarding some important parameters for risk analyses, e.g. the ignition probability has decreased and diverter systems have improved. Only 3.5% of the fatalities occurred because of blowouts. 106 refs., 51 figs., 55 tabs.
