Parasitología latinoamericana , 2005, DOI: 10.4067/S0717-77122005000200008
Abstract: the presence of kudoa sp in somatic muscle of cutless fish (trichiurus lepturus) captured at itaipu beach, niterói, rio de janeiro, is been reported. it was used as samples 47 specimes, measured and necropsied at the laboratório de inspe??o e tecnologia de pescado da faculdade de veterinária dauniversidade federal fluminense. the tissues were processed for paraffin inclusion and stained by hematoxilina-eosin. from the total samples, nine of them (19,15%) showed plasmodic type cists in muscular fibers without inflammatory reaction. it was four valves, the principal feature of the genus. the number of cysts varied from one to 15, with a average of 5,1. the length and width average of cysts were 82,57 and 28,27, respectively. the length average of positive fishes was 116cm. the smaller animal (68,0) showed more cysts. it was not observed myoliquefaction even several hours after captured
Designing a Nano Infrastructure for Brazil’s Amazon Water Resources: A Quadruple Helix Approach  [PDF]
Raul Gouvea
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.71005
Abstract: This paper elaborates on the role of green technologies and innovations in “greening” Brazil’s Amazon region fresh water resources. The paper elaborates on the development of an innovation quadruple helix to better manage the region’s water resources. Brazil accounts for close to 12% of the earth’s fresh water reserves, while most of it is in the Amazon region. The preservation of water reserves on a global scale is of paramount importance in the 21st century. Brazil, however, has not managed its water resources effectively leading to the increasing pollution and contamination of its Amazonian water resources.
Generational Change and the Military Dictatorship in Brazil: The Debate on the “AI-5 Generation”  [PDF]
Silvana Seabra Hooper
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.715226
Abstract: This article analyzes the issue of generational change, reviews its conceptual and historical origin in Mannheim and demonstrates the relationship between generational cohorts and traumatic historical moments. The paper focuses on a new generation in Brazil, the “AI-5 generation” (1970), which was identified by Luciano Martins (social scientist), and subsequently reconsidered by Jurandir Freire Costa (social psychanalyst). It discusses one possible reinterpretation of the concept within the context of the internationalization and modernization of that period in Brazil.

The knowledge of the epidemiology of parasitic infections in stray and domestic animals, especially of its incidence and prevalence, is fundamental to adopting effective prophylactic measures. Stray dogs play an important role in environmental contamination favoring the transmission cycle of zoonotic agents. Among the parasitic infections that affect humans, Giardia duodenalis is the most common intestinal protozoa and was designated as a re-emerging infectious disease. This study aimed to determine the prevalence of G. duodenalis in dogs siezed by the Center for Control of Zoonoses (CCZ) of the city of Lages, Santa Catarina, Brazil using two diagnostic techniques. In 357 stool samples analysed, the prevalence of G. duodenalis cysts was 5.3% (19/357) and 4.8% (17/357) detected by floatation and sedimentation techniques, respecttively. No correspondence between gender and age was found among the methods used for analyzing the infected dogs in this study. Our data suggested that two diagnostic techniques should be used in a complementary way to ensure that false negatives are not neglected.

American Journal of Climate Change (AJCC) , 2017, DOI: 10.4236/ajcc.2017.63027
Abstract: Given the high and increasing lightning incidence over the Southeast of Brazil and the various impacts that this phenomenon generates to society, there is a growing need in predicting its occurrence, in order to minimize its consequences. In this context, this work presents the development of a methodology for the projection of lightning in the State of S?o Paulo (Southeastern Brazil), using the HadGEM2-ES and CSIRO-Mk3.6 models in two IPCC climate change scenarios: RCP4.5 and RCP8.5. Since lightning is not an output variable of climate models, tests were carried out to evaluate the relationship between the observed data of oceanic and atmospheric fields, which are known as outputs of the models, and the lightning from the RINDAT and BrasilDAT detection networks. As result, a correlation of 0.84 was obtained. In the projections, it was verified that, while during a large portion of the current climate we observed events of lightning below the average, the future climate reveals the preponderance of anomalously above average events, both in the scenario of intermediate-low emissions (RCP4.5) and in the scenario of high emissions (RCP8.5), suggesting a change in the pattern of the lightning incidence in the State of S?o Paulo.
Política de comércio exterior e desenvolvimento: a experiência brasileira
Cervo, Amado Luiz;
Revista Brasileira de Política Internacional , 1997, DOI: 10.1590/S0034-73291997000200001
Abstract: the article exposes the brazilian government thought and brazilian external trade policy between 1930 and nowadays. three verifications of brazilian diplomacy have conditioned brazilian decision-making process: doctrines do not guide the practice of great powers, an emergent country disposes of little power in multilateral fora, radical liberal experiences do not produce the effects proclaimed by their indoctrinators. for this reason, the international trade policy avoided to obey the major principles and models, orienting itself with growing realism. it has been historicaly developed as an instrument to reinforce the internal economy and market, and it has evolved based on a contradictory strategy that protected the internal market and cried out for global markets openning. on the 90's, it has ceded to globalization tendencies, but not before it had extended introspection to the broaden regional market, mercosul.

Macinko James,Mullachery Pricila,Proietti Fernando A,Lima-Costa Maria Fernanda
International Journal for Equity in Health , 2012, DOI: 10.1186/1475-9276-11-80
Abstract: Introduction Perceived discrimination is related to poor health and has been offered as one explanation for the persistence of health inequalities in some societies. In this study, we explore the prevalence and correlates of perceived discrimination in a large, multiracial Brazilian metropolitan area. Methods The study uses secondary analysis of a regionally representative household survey conducted in 2010 (n=12,213). Bivariate analyses and multiple logistic regression assess the magnitude and statistical significance of covariates associated with reports of any discrimination and with discrimination in specific settings, including when seeking healthcare services, in the work environment, in the family, in social occasions among friends or in public places, or in other situations. Results Nearly 9% of the sample reported some type of discrimination. In multivariable models, reports of any discrimination were higher among people who identify as black versus white (OR 1.91), higher (OR 1.21) among women than men, higher (OR 1.33) among people in their 30’s and lower (OR 0.63) among older individuals. People with many health problems (OR 4.97) were more likely to report discrimination than those with few health problems. Subjective social status (OR 1.23) and low social trust (OR 1.27) were additional associated factors. Perceived discrimination experienced while seeking healthcare differed from all other types of discrimination, in that it was not associated with skin color, social status or trust, but was associated with sex, poverty, and poor health. Conclusions There appear to be multiple factors associated with perceived discrimination in this population that may affect health. Policies and programs aimed at reducing discrimination in Brazil will likely need to address this wider set of interrelated risk factors across different populations.
Nota sobre os limites e as possibilidades da era FHC
Schwartz, Gilson;
Lua Nova: Revista de Cultura e Política , 2000, DOI: 10.1590/S0102-64452000000100003
Abstract: the conditions and limits of moving from a stabilization policy towards one geared to economic development are examined with reference to two recent papers on fernando henrique cardoso's second presidential term. among those conditions, it is argued, is the reversal of the liberal-conservative stance through an emphasis on development, on the rebuilding of the state, and on the rehabilitation of the public sphere.
