    Abstract The lowland tapir (Tapirus terrestris) is found in South America and is listed as Vulnerable to Extinction by the International Union for Conservation of Nature, Red List of Threatened Species. Health issues, particularly infectious diseases, are potential threats for the species. Health information from 65 wild tapirs from two Brazilian biomes, Atlantic Forest (AF) and Pantanal (PA), were collected during a long-term study (1996-2012). The study included physic, hematologic and biochemical evaluations, microbiologic cultures, urinalysis, and serologic analyses for antibodies against 13 infectious agents (viral and bacterial). The AF and PA tapirs were significantly different for several hematologic and biochemical parameters. Ten bacteria taxa were identified in the AF and 26 in the PA. Antibodies against five viruses were detected: Bluetongue virus, eastern equine encephalitis virus, western equine encephalitis virus, infectious bovine rhinotracheitis virus, and porcine parvovirus. A high prevalence of exposure to Leptospira interrogans (10 serovars: Autumnalis, Bratislava, Canicola, Copenhageni, Grippotyphosa, Hardjo, Hebdomadis, Icterohaemorrhagiae, Pomona, and Pyrogenes) was detected in both the AF and PA sites. A greater diversity of serovars and higher antibody titers were found in the PA. Statistically significant differences between sites were found for L. interrogans, equine encephalitis virus, and porcine parvovirus. Based on physical evaluations, both AF and PA populations were healthy. The differences in the overall health profile of the AF and PA tapir populations appear to be associated with environmental factors and infectious diseases ecology. The extensive datasets on hematology, biochemistry, urinalysis, and microbiology results from this paper can be used as reference values for wild tapirs. PMID:25105810

    A study on the selection of food plants by captive Malayan tapirs (Tapirus indicus) was undertaken in a 30 hectare natural forest enclosure at the Sungai Dusun Wildlife Reserve, Malaysia. Tapirs browsed on 217 species of plants (from 99 genera and 49 families) from a total of the 1142 specimens collected and identified. Food plants were heavily dominated by sapling trees and shrubs which comprised 93% of all plants taken, with the remainder comprising woody lianas, vines and herbaceous plants. Although tapirs browsed on a wide variety of plant species, the top 30 species consumed represented more than 60% of all the plants selected, whilst the vast majority of species were rarely eaten. More than 80 species of trees and shrubs were available, but not eaten at all. The most readily consumed species were the sub-canopy and understorey trees Xerospermum noronhianum, Aporosa prainiana and Baccaurea parviflora, while Aporosa, Knema and Xerospermum were the dominant plant genera. The Phyllanthaceae (leaf flowers), Myristicaceae (nutmegs) and Sapindaceae (rambutans) were the most commonly selected families comprising 45% of the diet. Tapirs fed on saplings trees up to 8.3 m in height, while plants taller than about 1.6 m were bent, broken or pushed to the ground to gain access to the foliage. Sapling stems up to 4.2 cm in diameter could be snapped by biting, while larger trees to 7 cm diameter could be pushed down. Tapirs typically fed on the newer leaves and shoots, however, often only consuming half of the available foliage on a plant. This study documents 160 new plant species suitable as Malayan tapir food, and is consistent with the generalist, but selective browsing nature of the Tapirus species in general.

    The Malayan, or Asian, tapir (Tapirus indicus) has a diminishing wild population and is becoming more common in captivity as zoos attempt to manage sustainable ex situ populations. Tapirs can be relatively easy to maintain and breed, but captive animals appear to suffer from reduced activity budgets, obesity, and poor public image. A questionnaire-based survey was designed and sent specifically to 10 collections around the world that exhibit Malayan tapirs, with the aim of assessing husbandry regimes to determine prevalence of standardized practices as well as highlighting any key differences, and to showcase good practice, thus providing information beneficial to those maintaining this species in their zoo. Twenty-five animals were included in the survey from collections across four continents. The research's major conclusions show differing dietary make-up, with a lack of forage provision, contrasting with a diverse array of enrichment protocols used. Significant differences were noted between zoos for total amount of food offered (P = 0.000) as well as ratios of forage to concentrate pellet offered (P = 0.004). Comparing food offered to male and female tapirs with published requirements for an "average" of either gender shows not all zoos providing the amount suggested in husbandry guidelines. Intelligently designed and original enrichment was provided to all animals but differences between zoos were noted in the application and "usefulness" of enrichment for individual tapir. Overall, animals are benefiting from enrichment but welfare could be further improved via consistent feeding of ad libitum forage and regular use of browse as a constituent part of daily rations.

    This note reports a historic record of the Central American Tapir, Tapirus bairdii, for the Coastal Plain of the Isthmus of Tehuantepec in Oaxaca, Mexico. The record was dated to the decade of 1950, and was found 40 km from the closest historic locality. The presence of this species suggests two hypotheses: that the observed specimens belong to a previously existing population in this region, or that these specimens come from the Los Chimalapas region.

    The health of a population of free-ranging tapirs (Tapirus bairdii) inhabiting Corcovado National Park, Costa Rica, was assessed as part of an ongoing ecologic study. Nineteen tapirs were immobilized between March 1997 and February 2000, and samples of blood, skin biopsies, and ectoparasites were collected. Ticks were identified as Amblyomma oblongoguttatum or A. coelebs. Hematology and serum biochemistry results suggest statistically significant differences between free-ranging and captive populations that should be interpreted with caution in view of inherent environmental differences between the two populations. Five of 17 animals tested positive for Leptospira bratislava, and 12 individuals tested positive for Venezuelan equine encephalitis. One of nine skin biopsies examined was abnormal and diagnosed as leukoderma. This report represents the first health assessment of a free-ranging population of tapirs. PMID:17323556

    We sequenced the mitochondrial cytochrome b gene of 141 lowland tapirs (Tapirus terrestris) - representing the largest geographical distribution sample of this species studied across of South America to date. We compare our new data regard to two previous works on population structure and molecular systematics of T. terrestris. Our data agree with the Thoisy et al.'s work in (1) the Northern Western Amazon basin was the area with the highest gene diversity levels in T. terrestris, being probably the area of initial diversification; (2) there was no clear association between haplogroups and specific geographical areas; (3) there were clear population decreases during the last glacial maximum for the different haplogroups detected, followed by population expansions during the Holocene; and (4) our temporal splits among different T. terrestris haplogroups coincided with the first molecular clock approach carried out by these authors (fossil calibration). Nevertheless, our study disagreed regard to other aspects of the Thoisy et al.'s claims: (1) meanwhile, they detected four relevant clades in their data, we put forward six different relevant clades; (2) the Amazon River was not a strong barrier for haplotype dispersion in T. terrestris; and (3) we found reciprocal monophyly between T. terrestris and T. pinchaque. Additionally, we sequenced 42 individuals (T. terrestris, T. pinchaque, T. bairdii, and the alleged "new species", T. kabomani) for three concatenated mitochondrial genes (Cyt-b, COI, and COII) agreeing quite well with the view of Voss et al., and against of the claims of Cozzuol et al. Tapirus kabomani should be not considered as a full species with the results obtained throughout the mitochondrial sequences. PMID:26000940

    Lowland tapir distribution is described in northwestern Bolivia and southeastern Peru within the Greater Madidi-Tambopata Landscape, a priority Tapir Conservation Unit, using 1255 distribution points derived from camera trapping efforts, field research and interviews with park guards from 5 national protected areas and hunters from 19 local communities. A total of 392 independent camera trapping events from 14 camera trap surveys at 11 sites demonstrated the nocturnal and crepuscular activity patterns (86%) of the lowland tapir and provide 3 indices of relative abundance for spatial and temporal comparison. Capture rates for lowland tapirs were not significantly different between camera trapping stations placed on river beaches versus those placed in the forest. Lowland tapir capture rates were significantly higher in the national protected areas of the region versus indigenous territories and unprotected portions of the landscape. Capture rates through time suggested that lowland tapir populations are recovering within the Tuichi Valley, an area currently dedicated towards ecotourism activities, following the creation (1995) and subsequent implementation (1997) of the Madidi National Park in Bolivia. Based on our distributional data and published conservative estimates of population density, we calculated that this transboundary landscape holds an overall lowland tapir population of between 14 540 and 36 351 individuals, of which at least 24.3% are under protection from national and municipal parks. As such, the Greater Madidi-Tambopata Landscape should be considered a lowland tapir population stronghold and priority conservation efforts are discussed in order to maintain this population.

    One common visitor complaint in zoos is that the nonhuman animals are not visible. This problem needs to be resolved without compromising the animals' welfare; environmental enrichment could solve the problem. This study investigated whether enrichment would increase public exposure time of lowland tapir (Tapirus terrestris) in the Belo Horizonte Zoo in Minas Gerais, Brazil. Observations were made before (62 hr) and during (62 hr) the introduction of enrichment using focal animal sampling with instantaneous recording of behavior. The 5 enrichment items were a bamboo fence covered in vines, logs, a sandbox, dry leaves, and bamboo bushes. Before the enrichments were applied, the tapir was not visible to the public for more than 85% of the time. In addition, during the analysis of the enrichment treatment, other variables were considered--such as weekday, time of day, and weather conditions--which could influence the animals' interaction with the enrichments. The enrichments increased and decreased the expression of some behaviors; however, public viewing time of the animals did not increase. Thus, the enrichment applied was not strong enough to overcome the animals' crepuscular behavior. PMID:25117174

    Tapirs (Tapirus sp.) have been studied extensively in the wild, yet little is known about their fundamental reproductive biology, information that is critical to establishing self-sustaining populations in captivity as a hedge against extinction. This paper reviews information on the reproductive biology of the 4 species of tapirs: Baird's (Tapirus bairdii), lowland (T terrestris), mountain (T pinchaque) and Malayan (T indicus). Both sexes reach puberty between 14 and 48 months of age. Behaviorally, tapirs display few overt signs of estrus, and external signs of pregnancy are not evident until approximately 2 months before parturition. Immunoassay techniques to measure reproductive hormones in blood and urine have been validated for tapirs, which allow monitoring of ovarian cycle activity and pregnancy. Data indicate that females are polyestrous, with an estrous cycle length of approximately 30 days. The exception is the Malayan tapir, which exhibits 2 types of cycles: short (approximately 1 month) and long (approximately 2 months). Gestation length is approximately 13 months and females can conceive at the first post-partum cycle within 1 month after birth. Good quality ejaculates have been obtained via electroejaculation in the Baird's and Malayan tapir and the sperm from Baird's tapir cryopreserved using standard cryodiluents, although more work is needed to optimize these protocols. Given that all 4 species of tapir most likely will continue to be maintained in captivity, effective genetic management is vital for long-term survival. Optimization of assisted reproductive technologies, including sperm cryopreservation and artificial insemination, could benefit the genetic management of tapirs. PMID:23586557

    The Southeast Asian zoogeographical region is divided into Indochinese, Sundaic and Philippine subregions. Two clades of tapirs, Tapirus spp., have been recognized in Quaternary Southeast Asia. A review of sites at which they occurred shows that representatives of both clades, one of which was the ancestral Malayan tapir Tapirus indicus, co-existed with a diversity of other Pleistocene mammal megafauna. The process of replacement of archaic large mammals was progressive and prolonged through the Quaternary. Zooarcheological investigation has extended knowledge of the former occurrence and distribution of tapirs and other large mammals of the region, with discoveries beyond the outer limits of their previously known ranges. These large mammals were subjected to paleoenvironmental changes as a consequence of the Quaternary cycles of glacial and interglacial periods. Archeological evidence suggests that hunting pressure has intensified the effects of altered environments, leading ultimately to the local disappearance of the Malayan tapir in most of Southeast Asia, including Borneo. The survival of the Malayan tapir through the Quaternary until the present shows that the species is both resilient to environmental change and flexible in its ecological re'uirements and, given proper protection, could continue to inhabit tropical Southeast Asia. To assist the species conservation, reintroduction is proposed from the remaining range of Malayan tapir in the wild, to suitable sites of past occurrence in Borneo, where these ancient survivors of the Quaternary megafauna can be accommodated and safeguarded alongside other forms of land usage.

    Tapirs are one of the last extant megafauna species that survived the Pleistocene extinctions. Given their size and digestive system characteristics, tapirs might be the last potential seed disperser of plant species that were previously dispersed by other large mammal species that are now extinct. We compiled evidence from 39 published scientific studies showing that tapirs have a key role as seed dispersers and seed predators. Tapirs play an important role either through seed predation or by facilitating the recruitment of seeds over long distances, therefore influencing the diversity of plant species in the ecosystem. Neotropical tapirs might have a unique role as long-distance seed dispersers of large seeds (germination that even large-bodied primates cannot disperse. Given the high diversity of seed species found in tapir diet, more information is needed on the identification of seed traits that allow the survival of seeds in the tapir's gut. Moreover, further studies are necessary on the role of tapirs as seed dispersers and predators; in particular considering spatial patterns of dispersed seeds, seed viability, effect of dung, and seed density in tapir latrines, and the effect of deposition sites on germination and seedling survival. Because all tapir species are highly threatened, it is paramount to identify gaps in our knowledge on the ecological role of tapirs and, in particular, on critical and endangered plant-tapir interactions to avoid possible trophic cascading effects on ecosystem function.

  6. Botany, genetics and ethnobotany: a crossed investigation on the elusive tapir's diet in French Guiana.

    Fabrice Hibert

    Full Text Available While the populations of large herbivores are being depleted in many tropical rainforests, the importance of their trophic role in the ecological functioning and biodiversity of these ecosystems is still not well evaluated. This is due to the outstanding plant diversity that they feed upon and the inherent difficulties involved in observing their elusive behaviour. Classically, the diet of elusive tropical herbivores is studied through the observation of browsing signs and macroscopic analysis of faeces or stomach contents. In this study, we illustrate that the original coupling of classic methods with genetic and ethnobotanical approaches yields information both about the diet diversity, the foraging modalities and the potential impact on vegetation of the largest terrestrial mammal of Amazonia, the lowland tapir. The study was conducted in the Guianan shield, where the ecology of tapirs has been less investigated. We identified 92 new species, 51 new genera and 13 new families of plants eaten by tapirs. We discuss the relative contribution of our different approaches, notably the contribution of genetic barcoding, used for the first time to investigate the diet of a large tropical mammal, and how local traditional ecological knowledge is accredited and valuable for research on the ecology of elusive animals.

    While the populations of large herbivores are being depleted in many tropical rainforests, the importance of their trophic role in the ecological functioning and biodiversity of these ecosystems is still not well evaluated. This is due to the outstanding plant diversity that they feed upon and the inherent difficulties involved in observing their elusive behaviour. Classically, the diet of elusive tropical herbivores is studied through the observation of browsing signs and macroscopic analysis of faeces or stomach contents. In this study, we illustrate that the original coupling of classic methods with genetic and ethnobotanical approaches yields information both about the diet diversity, the foraging modalities and the potential impact on vegetation of the largest terrestrial mammal of Amazonia, the lowland tapir. The study was conducted in the Guianan shield, where the ecology of tapirs has been less investigated. We identified 92 new species, 51 new genera and 13 new families of plants eaten by tapirs. We discuss the relative contribution of our different approaches, notably the contribution of genetic barcoding, used for the first time to investigate the diet of a large tropical mammal, and how local traditional ecological knowledge is accredited and valuable for research on the ecology of elusive animals.

  9. Functional redundancy and complementarities of seed dispersal by the last neotropical megafrugivores.

    Directory of Open Access Journals (Sweden)

    Rafael S Bueno

    Full Text Available BACKGROUND: Functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. Large bodied frugivores may disperse similar plant species and have strong impact on plant recruitment in tropical forests. The two largest frugivores in the neotropics, tapirs (Tapirus terrestris and muriquis (Brachyteles arachnoides are potential candidates for functional redundancy on seed dispersal effectiveness. Here we provide a comparison of the quantitative, qualitative and spatial effects on seed dispersal by these megafrugivores in a continuous Brazilian Atlantic forest. METHODOLOGY/PRINCIPAL FINDINGS: We found a low overlap of plant species dispersed by both muriquis and tapirs. A group of 35 muriquis occupied an area of 850 ha and dispersed 5 times more plant species, and 13 times more seeds than 22 tapirs living in the same area. Muriquis dispersed 2.4 times more seeds in any random position than tapirs. This can be explained mainly because seed deposition by muriquis leaves less empty space than tapirs. However, tapirs are able to disperse larger seeds than muriquis and move them into sites not reached by primates, such as large forest gaps, open areas and fragments nearby. Based on published information we found 302 plant species that are dispersed by at least one of these megafrugivores in the Brazilian Atlantic forest. CONCLUSIONS/SIGNIFICANCE: Our study showed that both megafrugivores play complementary rather than redundant roles as seed dispersers. Although tapirs disperse fewer seeds and species than muriquis, they disperse larger-seeded species and in places not used by primates. The selective extinction of these megafrugivores will change the spatial seed rain they generate and may have negative effects on the recruitment of several plant species, particularly those with large seeds that have muriquis and tapirs as the last living

    1981-04-01

    Brazil counts as a gemmological province because of the variety of gem minerals present in the country. Most Brazilian states and territories produce gemstones, the State of Minas Gerais being the most important producer both in volume and in number of species. Diamonds are chiefly derived by panning from alluvial deposits in Minas Gerais, Mato Grosso and Goiás. Among other gemstones, the most important are aquamarines, beryls, chrysoberyls, topazes, amethysts, tourmalines, emeralds and agates, and their respective varieties. The occurrences of these gemstones, as well as of a great number of others, are described for each state in which they are found.

    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.

    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.

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.

    The growing number of Internet users brought forth an increase in the search for Brazilian online pharmacy services. Aiming at evaluating the validity of information disseminated in these websites, a descriptive study was carried out in 18 virtual pharmacies concerning legal aspects, accessibility, sources of information and drug advertising. It was found 15 pharmacies did not have authorization of the Brazilian National Health Surveillance Agency; the manager pharmaceutical officer's name could not be found in 17 of them; 17 pharmacies marketed drugs with no registration, especially herbal medicines, and did not show either information on adverse drug reactions or this agency's alerts and health recommendations. Since health control and drug commerce in Brazilian online pharmacies have not been yet regulated by proper government agencies, these gaps found in the sites can pose risk to the users' health.

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.

  17. The Brazilian sugarcane innovation system

    International Nuclear Information System (INIS)

    Ethanol has recently been of great interest worldwide because it is a viable economic alternative to petroleum products and it is a renewable source of energy that mitigates the emission of greenhouse gases. Brazilian bioethanol from sugarcane is the most successful case at the world level because of its low cost and low level of greenhouse gas emissions. Brazil's success with sugarcane cannot be understood as based solely on a natural comparative advantage, but as a result of efforts that culminated in a positive trajectory of technological learning, relying mostly on incremental innovations. The purpose of this article is to analyze the key aspects of the innovation system built around the Brazilian sugarcane industry. It is based on the national innovation systems approach according to which innovation results from the interaction of different institutional actors. Institutional arrangements are analyzed as the basis for the innovative process, in particular R and D and the innovation policies and strategies of the main players in the sugarcane sector, including sugar and ethanol mills, industrial goods suppliers, public and private research institutions, and governmental agencies. - Research Highlights: → The Brazilian success in bioethanol is due to the sugarcane innovation system. → Private funds for R and D became central after IAA closure. → Nowadays Brazilian innovation system is transforming to keep its leadership. → Public funds for research in the second generation bioethanol.

    Full Text Available Studies to evaluate environmental impacts have become both a need and a requirement of environmental agencies due to great alteration of the native environments provoked by man. Many of these studies are short-termed, but reporting the acquired data is very important in order to increase knowledge about specific biotic groups. Thus, this paper presents the results of the non-volant mammal surveys arising from seven environmental studies in southern Brazil. The following methodologies were employed: (1 interviews with local residents; (2 visual observations and recording; (3 identification of vestiges; and (4 capture with live traps. A total of 46 mammal species were recorded (5 marsupials, 4 xenarthrans, 2 primates, 13 carnivores, 2 artiodactylans, 2 lagomorphs and 18 rodents. Some species, such as the jaguar (Panthera onca, giant otter (Pteronura brasiliensis, Brazilian tapir (Tapirus terrestris and white-lipped peccary (Tayassu pecari, are possibly extinct or seriously threatened. The records obtained and the possibilities of the occurrence of other species are discussed.

  3. A Comparison of Zoo Animal Behavior in the Presence of Familiar and Unfamiliar People.

    Martin, Rosemary Anne; Melfi, Vicky

    2016-01-01

    As recorded in domestic nonhuman animals, regular interactions between animals in zoos and keepers and the resulting relationship formed (human-animal relationship [HAR]) are likely to influence the animals' behaviors with associated welfare consequences. HAR formation requires that zoo animals distinguish between familiar and unfamiliar people. This ability was tested by comparing zoo animal behavioral responses to familiar (routine) keepers and unfamiliar keepers (participants in the "Keeper for the Day" program). Study subjects included 1 African elephant (Loxodonta Africana), 3 Rothschild's giraffes (Giraffa camelopardalis rothschildi), 2 Brazilian tapir (Tapirus terrestris), and 2 slender-tailed meerkats (Suricata suricatta). Different behavior was evident and observed as decreased avoidance behavior toward familiar keepers (t7 = 6.00, p zoo animals have a lower level of fear toward familiar keepers. Keeper familiarity did not significantly affect any other behavioral measure. This finding suggests that in the current study, unfamiliar keeper presence did not appear to have detrimental effects. Furthermore, unfamiliar keeper-animal interactions could provide an increased number of positive human-animal interactions and potentially enhance animal welfare. PMID:26960022

  4. 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.

  5. Brazilian Studies Then and Now

    Directory of Open Access Journals (Sweden)

    Anthony Pereira

    2012-09-01

    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.

    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)

    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

  10. Pathways to Internationalize Brazilian Journals of Psychology

    2015-01-01

    Full Text Available 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 internationalize the existing Brazilian journals. With regard to the latter possibility, a metric analysis of scientometrics databases suggests that the reasons for the low impact of articles published in Brazilian journals are manifold, but the low performance is mainly explained by the scarce employment of the lingua franca-English language-in the articles. This article discusses the role that SciELO, a Brazilian scientific publisher, has played in indexing and assisting the best Brazilian psychology journals in raising their horizons, in terms of internationalizing their output, while at the same time serving as an instrument of promotion for national studies of psychology within the country of Brazil.

    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.

  20. 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.

    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.

  3. The Brazilian electrical system reform

    International Nuclear Information System (INIS)

    Although the Brazilian electrical system has been a public monopoly, the threat of electricity shortages from a lack of investment triggered a comprehensive reform. In 1993 the government began a series of laws, decrees and regulations reforming the tariff policy, allowing privatization of utilities, foreign investments and independent power producers, and creating an independent transmission grid and a new electricity regulatory agency (ANEEL). The new regulatory framework is not completely defined but the proposed model intends to transform bulk electricity supply into a competitive market similar to that adopted in England. Our objective is to evaluate whether the proposed reform will succeed in attracting the required private capital, will allow an unregulated wholesale electricity market and will require a strict regulatory framework. The reform has been quite successful in privatizing the distribution companies but is allowing monopolistic rents, and has failed until now to attract private investments to expand generation capacity. The risk of blackouts has increased, and the proposed wholesale electricity market may not be appropriate because of barriers to constructing new hydroelectric units, now 90% of the system. Therefore, a new regulatory framework and a strong regulatory agency with a well-defined tariff policy should have preceded the privatization. (author)

    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)

    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.

    Full Text Available Huntington disease (HD is associated with expansions of a CAG trinucleotide repeat in the HD gene. Accurate measurement of a specific CAG repeat sequence in the HD gene in 92 Brazilian controls without HD, 44 Brazilian subjects with clinical findings suggestive of HD and 40 individuals from 6 putative HD families, showed a range from 7 to 33 repeats in normal subjects and 39 to 88 repeats in affected subjects. A trend between early age at onset of first symptoms and increasing number of repeats was seen. Major increase of repeat size through paternal inheritance than through maternal inheritance was observed. Data generated from this study may have significant implications for the etiology, knowledge of the incidence, diagnosis, prognosis, genetic counseling and treatment of HD Brazilian patients.

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 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 The history of Brazilian neuropsychology is traced at different neuropsycholinguistic stages with a focus on the importance of sociocultural factors. We first focus on language disorders, the sequelae of injuries in the left hemisphere, and neuropsychology restricted to the medical field in Europe, the United States, and Brazil. In the middle of the last century, attention to the interdisciplinary importance of studies on the right hemisphere began. Studies consequently emerged on the individual variability of brain function with both biological and cultural origins. Based on this approach, Brazilian studies on aphasic children and illiterate aphasic persons were disseminated internationally. In the 1970s, cognitive neuropsychology began in England, highlighting dysfunctions in reading and writing processes. The characteristics of writing systems within each language became relevant for the manifestations of acquired dyslexia. Brazilian studies showed deficits in Portuguese and Japanese writing caused by brain lesions. During this scientific journey, scientific societies and postgraduate programs in Brazil were created to facilitate exchanges and communication among young researchers. By the end of the last century and in the early 2000s, the growth of the neuropsychology of aging raised awareness of the complexity of sociocultural factors, not only on language research but also according to the level of education, frequency of reading and writing habits, school type, and interactions among these factors and biological factors, especially between the level of education and age. From this historical standpoint, we outline future directions and perspectives in the field of Brazilian neuropsychology.

    Fabio Moura

    2015-09-01

    Full Text Available 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. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

  13. Earning management in Brazilian financial institutions

    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.

    2001-12-01

    An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq) responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999). In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997) or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications) to 2000 (12,686 scientific publications). Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

  1. 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.

  3. [Brazilian colonization in the Paraguayan agricultural frontier].

    Neupert, R F

    1991-04-01

    This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

Using track traps installed on araticum plants, the frequency of visitation (FV and the fruit consumption by the animals was assessed, as well as, the action of insects in fallen fruits under the trees was registered. Sample of tapirs excrement Tapirus terrestris were analyzed to verify the occurrence frequency (FO and the damage caused on the seeds by tapirs and insects. To analyze the dispersal by tapirs, colored beads were inserted in fallen mature fruits under the parent trees. Then, the distance between the location of the excrements with beads to the parent tree in the specific color of the bead was measured. Germination test was performed with excrement samples and unbroken fruit seeds. Among the animals that fed on fruits, tapirs contributed with the largest frequency of visitation and consumption of araticum fruits, representing 54% of the frequency occurrence in excrement samples, and the seeds were not damaged significantly. Dung beetles (Scarabaeidae fed the pulp of the fruit and buried araticum seeds next to the parent tree. Curculionid and eurytomid insects predated the araticum seeds on the fruits. The damage caused by these insects in the seeds was significantly higher than those caused by tapirs. Two excrements with beads were found at 1,7 and 1,8km distant from the parent trees, respectively. The seeds had low germinability in this period of study, however the tapirs can protect the seeds of predator insects, defecating the intact seeds for long distances. Thus, T. terrestris is a possible disperser of seeds, whereas curculionids and eurytomids can be considered predators of araticum seeds. These relations

    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.

The genealogies of the cultivars were obtained based on information from marketing folders, websites, crossings records, and scientific articles. The following factors were calculated: relative genetic contribution (RGC, accumulated genetic contribution (AGC, frequency (in percentage of each ancestor in the genealogy (FAG, number of ancestors that constitute each cultivar (NAC,number of ancestors responsible for 60%, 70%, 80% and 90% of the genetic base (NAGB, and average number of ancestor per cultivar (ANAC. The cultivars were also grouped based on the period of release (1965-1980, 1981-1990, 1991-2000 and 2001-2012. For each grouping, the previously described factors were also estimated. A total of 110 cultivars were studied and it was concluded that the genetic base of Brazilian irrigated rice cultivars is narrow.

    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.

  8. 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)

  10. The Brazilian calibration network for radiodiagnostics

    International Nuclear Information System (INIS)

    Coordination of the Brazilian Calibration Network for the radiodiagnostic dosimetry and quality control is the responsibility of the National Ionizing Radiation Metrology Laboratory (LNMRI) of the Radioprotection and Dosimetry Institute (IRD). The LNMRI/IRD is the Institute working in metrology, dosimetry and radioprotection at the National Nuclear Energy Commission (CNEN). The IRD is designated by the Brazilian Government through the National Institute for Metrology (INMETRO) to maintain and disseminate the national ionizing radiation dosimetry standards and quantities related to the ionizing radiation. The idea for that network is to establish partnership in the implementation of health improvement programmes - the primary goal of the Brazilian Government. Some of these programmes are related to the medical applications of the ionizing radiation and it is so important that it is part of the main strategic planning of the following institutions involved in this subject: - National Sanitary Inspection Agency (ANVISA); - National Nuclear Energy Commission (CNEN); - Health Ministry (MS). The Health Ministry of Brazil established the regulation named Portaria MS 453 in order to regulate the quality control and inspection in hospitals and clinics that use X ray for medical diagnostics. The National Sanitary Inspection Agency, in adherence to this regulation, is implementing at each State body the sanitary inspection compliance control. In parallel, there is a great demand for equipment acquisition and staff training all over Brazil. Many universities are implementing graduation and post graduate courses in order to cover the lack of specialized personnel at ANVISA, hospitals and service companies for running this programme The LNMRI/IRD provides traceable standards in radiation therapy, diagnostic radiology and radiation protection and coordinates this Brazilian metrology network to develop all Brazilian diagnostic metrology centres, take care of the implementation of

    The aim of this study was to evaluate the adequacy of the Brazilian legislation about fluoride toothpaste. A search was conducted in LILACS, Medline and SciELO databases about the fluoride concentration found in Brazilians toothpastes, using descriptors on health. Publications since 1981 have shown that some Brazilian toothpastes are not able to maintain, during their expiration time, a minimum of 1,000 ppm F of soluble fluoride in the formulation. However, the Brazilian regulation (ANVISA, Resolution 79, August 28, 2000) only sets the maximum total fluoride (0.15%; 1,500 ppm F) that a toothpaste may contain but not the minimum concentration of soluble fluoride that it should contain to have anticaries potential, which according to systematic reviews should be 1,000 ppm F. Therefore, the Brazilian regulation on fluoride toothpastes needs to be revised to assure the efficacy of those products for caries control. PMID:26487295

    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)

    This special issue includes invited and selected articles of the VIIth Brazilian Meeting on Simulational Physics (BMSP), held in João Pessoa, Paraíba, Brazil, from the 5th to 10th August, 2013. This is the seventh such meeting, and the first one to have contributed papers published in the Journal of Physics: Conference Series. The previous meetings in the BMSP series took place in the mountains of Minas Gerais and in the region of the Brazilian Pantanal. Now, for the first time, the Meeting was held in the pleasant shores of João Pessoa, the capital of the Paraíba state. The VIIth BMSP brought together more than 50 researchers from all over the world for a vibrant and productive period. As in the previous meetings, the talks and posters highlighted recent advances in applications, algorithms, and implementations of computer simulation methods for the study of condensed matter, materials, out of equilibrium, quantum and biologically motivated systems. We are sure that this meeting series will continue to provide a valuable venue for people working in simulational physics to exchange ideas and discuss the state of art of this always expanding field. We are very glad to realize this special issue, and are most appreciative to the editors of the Journal of Physics: Conference Series for making this publication possible. We are grateful for the outstanding work of the João Pessoa team, for the financial support of the Brazilian agencies CNPq, CAPES, FAPESQ, and of the Federal Universities UFPB and UFMG. At last, but not least, we would like to acknowledge all of the authors of this special issue for their contributions. João Antonio Plascak Alexandre Rosas Guest Editors Conference photograph

  20. The Brazilian external individual monitoring scenario

    International Nuclear Information System (INIS)

    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)

    Houghton, R. A.

    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.

    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

The samples were collected on a monthly basis from June 2005 to May 2006, taken to the laboratory and incubated in moist chambers. Higher number of taxa was observed in the excrements of tapir, followed by deer and donkey. The highest number of species was detected for Mucor, followed by Pilobolus. Statistical analyses showed significant differences in richness of Zygomycetes taxa between the herbivore dung types. Differences of species composition, however, were weak. Seasonality influenced the Zygomycetes species composition but not its richness. Variations in taxa composition between ruminants and non-ruminants dung were non significant.

  1. Environemtnal benefits of the Brazilian Ethanol Programme

    International Nuclear Information System (INIS)

    After nearly twenty years since it was first launched, the Brazilian Ethanol Programme to data remains the largest commercial application of biomass for energy production and use in the world. It succeeded in demonstrating the technical feasibility of large scale ethanol production from sugar cane and its use to fuel car engines. On social and economic grounds, however, its evaluation is less positive. The purpose of this study is to provide an updated overview of the perspectives for the Ethanol Programme under the light of increasingly important local and global environmental concerns. Major results show that after oil prices supported upon the basis of its contribution to curb the increase of air pollution in Brazilian cities and of the greenhouse effect. It is concluded that the very survival of the Ethanol Programme, depends upon adequate economic compensation considering its global environmental benefits. These are appraised with two scenarios based on the use of a Markal-like model to define the range and costs of curbing greenhouse gases with a policy aiming at extending the Ethanol Programme

  2. Protein Quality of Irradiated Brazilian Beans

    International Nuclear Information System (INIS)

    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 (∼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 The Brazilian education system provides a specific form of organization for the inclusive education of students with disabilities. Law No. 9394 dated December 20, 1996, “Lei de diretrizes e bases da educação nacional”, presents in Chapter V the “educação especial" as a form of organization offered to students "portadores de Necessidades especiais”. 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 This research has the objective was to characterize the small Brazilian companies about the knowledge of operations management tools that help in improving the administrative process for these organizations. For that we chose a more positivist strand which values quantitative aspects. The research can be descriptive and explanatory, applied and/or intervention. As for media, research can be classified as documentary, bibliographic and/or participant. The population for this study is composed by Brazilian small enterprises are characterized by having a lower or equal to R$ 3,600,000 (approximately 1,800,000 dollars gross annual income. To collect information regarding the diagnosis of the degree of knowledge of small entrepreneurs, it was used a structured questionnaire using gradual tracks in identification of the respondent and the firm. It was found that the majority of managers interviewed small enterprises does not use the operations management tools. Is because they do not know such tools or have no need for their use in their companies.

  6. The Brazilian nuclear power manpower development programme

    International Nuclear Information System (INIS)

    Since the early stages of decision making, manpower availability has been recognized to be a key factor for the implementation of Brazil's nuclear power programme. Though care has been given to securing an industrial base and financial resources, the consequences of a lack of sufficient qualified manpower could be critical for the success of the whole programme. The broad scope of the Brazilian nuclear power programme which, as a main concept, aimed at establishing in the country a complete fuel cycle industry together with the construction of nuclear power plants, added another burden to the already complex task of providing appropriate human resources when advanced technologies are introduced in a developing country. Thus, not only the work-force required for nuclear power plant operation but also that needed for plant design, component manufacture, fuel cycle plant design and operation, had to be made available in number and qualification in accordance with the standards of the nuclear industry. The feasibility of the Brazilian programme depended on a complete transfer of technology, essentially achieved through personnel training. Again, the process of manpower preparation for an efficient know-how transfer required careful planning, and the great difficulty in its implementation was the lack of reliable experience at the time.

    2014-04-01

    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 The increasing problems with multidrug resistance in relation to Corynebacterium, including C. diphtheriae, are examples of challenges confronting many countries. For this reason, Brazilian C. diphtheriae strains were evaluated by the E-Test for their susceptibility to nine antibacterial drugs used in therapy. Resistance (MIC < 0.002; 0.38 µg/ml to penicillin G was found in 14.8% of the strains tested. Although erythromycin (MIC90 0.75 µg/ml and azithromycin (MIC90 0.064 µg/ml were active against C. diphtheriae in this study, 4.2% of the strains showed decreased susceptibility (MIC 1.0 µg/ml to erythromycin. Multiple resistance profiles were determined by the disk diffusion method using 31 antibiotics. Most C. diphtheriae strains (95.74% showed resistance to mupirocin, aztreonam, ceftazidime, and/or oxacillin, ampicillin, penicillin, tetracycline, clindamycin, lincomycin, and erythromycin. This study presents the antimicrobial susceptibility profiles of Brazilian C. diphtheriae isolates. The data are of value to practitioners, and suggest that some concern exists regarding the use of penicillin.

    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 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.

    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

  16. 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.

    We report here the first complete mitochondria genome of Onchocerca volvulus from a focus outside of Africa. 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. PMID:26814648

    Full Text Available – Ethnology studies report issues related to theatricality and spectacularity both in the scenic and ritual fields. Thus, theatre is one of the supports in ethnoscenological research, and this work focuses on Black Theater. Among the forms of representation of Blacks in Brazilian society, violence is one of the symbolic traits that has been re-signified in Afro-Brazilian texts. This essay aims at portraying some echoes of violence in dramatic/spectacular texts in Brazilian Black Theatre. We intend to discuss the instances in which violence is scenically represented and how this interferes with the (reconstruction of black identities and subjectivities.

  20. Implication of Amendment 49 in Brazilian radiopharmacy

    International Nuclear Information System (INIS)

    Full text: Amendment 49: Amendment 49, 8th february 2006, excludes from the monopoly of the Brazilian Government the production, the commercialization and the use of short half-life radiopharmaceuticals for medical, agricultural and industrial uses. The most recent modification of the Brazilian Constitution was gave for the alteration of the writing in the ''alinea b'', addition of a ''alinea c'' to the interpolated proposition XXIII of the caput of article 21 and for the new writing given to interpolated proposition V of the caput of article 177. Since its publishing a great effort of all regulatories agencies in Brazil have been made looking for the harmonization of national laws bu the Brazilian Nuclear Energy C omission, Health Surveillance Agency and Brazilian Pharmacopoeia. The growth of PET-technology and consequently the use of FDG-18 and the radiopharmaceuticals in general, request a specific regulation. This regulation must be supported in the tripod: security, effectiveness and quality (FINN, 1999). In the United States, the radiopharmaceuticals are regulated under a number of agencies, because they are radioactive materials, and also are prescribed as medicine, being administered to human being. Finn (1999) alert, however, that an explicit need for the specific regulation. This necessity can be demonstrated by the signature in 21 november of 1997, in form of law, of the ''Administration Modernization Act'' (FOOD AND DRUG ADMINISTRATION MODERNIZATION ACT, 1997) applied to the Food and Drug Administration (FDA). This act, in its structure, commands that the FDA, develops practical procedures and good manufacture practice for radiopharmaceuticals, including that used in PET. In Europe, the regulations (registration and production) is made by the publishing of various ECC rules (the first was in 1965's) that are published in the form of Directives and Decision. To date tere have been 33 Council Directives, one Council Decision and one Council Regulation. In

  1. Greenhouse Gas Emissions from Brazilian Sugarcane Soils

    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 This study analyzes extreme values in the daily returns of 45 Brazilian stocks between 2 January 1995 and 18 March 2009. The incidence of observations outside the range of three standard deviationsfrom the mean is at least five times greater than under the normal distribution. The occurrence of extreme values in the upper tail is 1.13 times higher than in the lower. The average of the extreme positive returns is higher than that of extreme negative returns. Half percent of the days determined the outcome of the investment. Extreme values are at least ± 7%. Investors should assess whether they will keep their holdings when returns of such magnitude occur. The characteristics of empirical distributions of stock returns favor the passive investor and the use of weight constraints in portfolio allocation models.

  3. MAPRAD: mapping of radioactivity in Brazilian soils

    International Nuclear Information System (INIS)

    The MAPRAD Project main objective is to increase the knowledge of the distribution of natural radioactivity in soils of Brazilian national territory and to provide (among others) information which are essential for medical geology and environmental radiation safety researches and for decision-making process regarding soil contamination levels. It also aims to make available the generated information for researchers and for public, through an online database. Soil samples are collected by the Geological Survey of Brazil (CPRM) and are sent to the Institute of Radioprotection and Dosimetry (IRD), National Commission of Nuclear Energy (CNEN), where they are processed and analyzed for determination of concentrations of radionuclides by gamma spectrometry. The results are inserted into a database containing the sample information as geographic coordinates of the samples and land use. After the sample analysis, results are made available for the scientific community access on Internet. (author)

    Marcelle Chauvet

    2002-03-01

    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.Este artigo utiliza vários métodos para datar e analisar ciclos de negócios e de crescimento no Brasil. Em particular, um modelo de mudanças de Markov é aplicado a dados de produção trimestrais e anuais. As probabilidades suavizadas dos estado markovianos são utilizadas como regras de previsão para definir as diferentes fases de flutuações cíclicas na produção real brasileira. Os resultados são comparados com diferentes regras não-paramétricas. Todos os métodos implementados geram uma cronologia similar e revelam assimetrias nas diferentes fases dos ciclos de negócio e crescimento do Brasil, nos quais os estados de baixo crescimento e recessão são de curta duração e mais

The angular and temporal resolutions at this frequency are ˜3‧ and 100 ms, respectively. Details of the array, analog/digital receiver system, and a preliminary East West one-dimensional solar image at the 1.6 GHz are presented in this paper.

  9. 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.

Differences in the bioactivity of extracts obtained from isolates from the same species were observed.

  11. 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.

    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.

    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...

  18. Bidding strategies in Brazilian electricity auctions

    International Nuclear Information System (INIS)

    Double bilateral contract auctions for electric energy purchase and sale occur in Brazil. These auctions present incomplete information and possess some subjectivity in relation to the future scenario of the Brazilian electric system, inserted in the agent's bids. In this work, a model using Bayes' rule and the game theory is proposed to aid the agent in its bid definition. Through the existing relations between the Conditional probabilities of Bayes' Rule, the model transforms beliefs into information. In this way, the absence of information is supplied and the problem is transformed into a game with complete information. The present study has no worries in terms of transmission constraints, since they are not usually considered in the bilateral contract auctions in Brazil. At the end, Nash equilibrium (NE) can be found through the expected payoff matrix of each agent. (author)

    2015-07-01

    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).

  20. Brazilian quartz purification by leaching technique

    International Nuclear Information System (INIS)

    High purity quartz powder presents an increasing demand for the production of silica glass, widely used for semiconductor processing, particularly for photo-voltaic solar cells manufacturing. Motivated by the huge natural quartz potential of this country, the present paper studied the cleansing effect of acid leaching on Brazilian quartz powder, investigating the following parameters: type of solvent, temperature and leaching time. Still, aqueous leaching tests with ultrasound activation were also performed in order to verify its efficiency. The ideal conditions found for leaching,with a 74,2% purification degree, were achieved using a mixture of hydrofluoric acid with hydrochloric acid at 100 deg C for 6 hours. A leaching procedure longer than 6 hours is not necessary, since Fe, Ca, K and Mg amounts do not show significant variation after such time. Also, aqueous leaching caused purification rates higher than 30% for most of the impurities tested, proving itself as a effective leaching method (author)

More than half of this production corresponds to around 200 different commercial types of granites with specific names, geographical and geological origins and mineral compositions. The well-known natural radioactivity present in rocks, where high radiation levels are associated with igneous rocks such as granite, can be used to determine their general petrologic features. This subject is important in environmental radiological protection, since granites are widely used as building and ornamental stones. In this paper, it is applied to correlate the petrographic characteristics of commercial granites with their corresponding dose rates for natural radioactivity. Amounts of thorium, uranium and potassium concentrations have been reported in several Brazilian commercial granite samples

    Santos, Wilson F N

    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 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

  4. Safety reviews of the Brazilian multipurpose reactor

    International Nuclear Information System (INIS)

    This work presents a model developed for thermal hydraulic (TH) simulation of the Multipurpose Brazilian Reactor (RMB), whose Brazilian proposal for design, construction and operation was established in 2007. This reactor has as main proposed the production of radioisotopes for use in exams of nuclear medicine, material tests and utilization of neutrons beams. Besides of the TH modeling and safety analysis of the reactor, the application of a methodology to perform coupled calculation thermal-hydraulic/neutron kinetic (TH/NK) is also presented. Initially, the RMB was modeled in the safety analysis RELAP5 code. This code performs the thermal hydraulic calculation using point kinetics. Subsequently, the model was adapted and verified to the RELAP5-3D© code. This code performs the process of internal coupling through the option of nodal neutron kinetics calculation using the NESTLE code which solves the neutron diffusion equation. To generate the neutronic group constants, which are macroscopic cross sections that serve as input data for the neutronic codes, it was used the WIMSD-5B cell calculation code. The neutron analysis code PARCS was also used to model the 3D RMB core in order to compare the results of radial and axial average power distribution with the results generated by RELAP5-3D© code and with the available results of the CITATION neutron kinetic code. The safety analyses demonstrated safe behavior of the reactor through situations of possible transients. The 3D coupled calculations to the steady state operation also showed expected behavior, as well as the RMB neutronic analyzes performed with the codes NESTLE and PARCS.(author)

We study firm-level relationship between stock returns and volatility for a sample of 25 time series of Brazilian stocks. Using Seemingly Unrelated Regressions (SUR empirical evidence suggests that contemporaneous returns and volatilities are significantly and positively correlated while there is a negative relationship between changes in volatility and stock returns. Finally, the asymmetric volatility effect seems to hold for Brazilian stocks as shown by the results from an AR(1-EGARCH(1,1 estimation.Este artigo examina a relação entre retornos de ações e volatilidade no período de junho de 1990 a abril de 2002.

    2011-03-01

    This study investigated the different ways of evaluating the social support in Brazilian studies. A surveying of scientific Brazilian publications from 1987 to 2007 was done in the Indexpsi, Pepsic, SciELO and Lilacs databases according to keywords social support and social network. Fifty-five studies included some type of assessing social support in Brazilian samples. The results indicated a rise in the number of studies about social support assessment in the last years using interviews to investigate received and perceived support, predominantly. However, the construction was applied without theoretical basis and was associated with many other concepts, sometimes without an appropriate articulation. Besides, there were evidences of lacking reliable, valid and standardized instruments to Brazilian population by considering the instruments currently used and revised by this study. PMID:21519666

    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.

  18. Incoherences of Brazilian labour laws face to present radioprotection concepts

    International Nuclear Information System (INIS)

    The Brazilian labour legislation establishes, since 1950, some privileges for people working in activities which imply exposure to ionizing radiations. Comparing the present legal framework with technical radioprotection knowledge, one can detect several incoherences covering: classification of such activities; additional payments; reduced labour journey; more vacations; medical surveillance; early retirements; special norms for women. An analysis of these incoherences lead us to propose a new frame of labour rights and radioprotection norms, coupling Brazilian juridical principles and modern radioprotection knowledge. (author)

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

  6. Gamma radiation measurements in Brazilian commercial granites

    International Nuclear Information System (INIS)

    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

    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 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 We have carried out an event study to investigate stock returns associated with the announcement of equity issues by Brazilian firms between 1992 and 2003 in order to determine market reaction before, during, and after the issue announcement. After measuring abnormal returns by OLS, we used ARCH and GARCH models over 70% of the sample. Our results are remarkably consistent with most of the international empirical literature. Some previous empirical findings have turned up abnormal returns before the announcement date, interpreted as signs of insider information. This evidence also appears in our study as we found an average cumulative abnormal return of –0.01 three weeks before the announcement. With respect to the announcement date, the evidence reported in the literature is virtually unanimous in showing negative abnormal returns, meaning that stock issues convey pessimistic information to the market. Our study confirms these findings with an average – 0.03 cumulative abnormal return on the first three days following the announcement. Finally, the empirical literature has also collected evidence of long-term negative abnormal returns after the issues, which we alsoconfirm, with an abnormal return of –0.28 after one year following the announcement. The results also show that ARCH/GARCH estimation of abnormal returns is superior to OLS estimation.

    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.

  12. 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.

    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.

    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.

    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.

    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 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.

    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. PMID:27367607

    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.

    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

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

  11. The Corporate Governance of Privately Controlled Brazilian Firms

    Directory of Open Access Journals (Sweden)

    Érica C. R. Gorga

    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.

    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.

    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 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.

    2004-12-01

    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.

    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.

  3. 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)

    Siqueira, C Eduardo; Roche, Andrea Gouveia

    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.

    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.

  7. PERSPECTIVE: Learning from the Brazilian biofuel experience

    Science.gov (United States)

    Wang, Michael

    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

  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.

    Directory of Open Access Journals (Sweden)

    Angelo Mondaini Calvão

    Full Text Available 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.

  10. Brazilian oil spills chemical characterization : case studies

    International Nuclear Information System (INIS)

    The Petrobras Research Centre has been active in responding to some significant oil spills in Brazil in the past decade. The centre has characterized spilled oil, monitored the affected ecosystems and determined the fate of oil in the environment. This paper described the use of some advanced chemical analytical techniques used in Brazilian oil spill studies to determine fractions and individual petroleum hydrocarbons in water, groundwater, sediment, sand, fish and the spilled oil itself. Some of the most recent oil spill cases were discussed in terms of chemical characterization of the spilled oil and the environmental samples from different matrices of the affected ecosystems for determining the fate of the oil in the environment and to assess environmental damage. In particular, methods such as gas chromatography/flame ionization detector, P and T/GC/PID and gas chromatography/mass spectrometry have been used to examine crude and fuel oil spills in Guanabara Bay, Barigui and Iguassu Rivers, and the Sao Sebastiao Channel. The chemical analytical methods are used to determine total petroleum hydrocarbons, n-alkanes, isoprenoids, unresolved complex mixtures, volatile monoaromatic compounds such as BTEX (benzene, toluene, ethylbenzene and xylenes), as well as parent and alkylated homologues polycyclic aromatic hydrocarbons (PAH) and terpanes and steranes. Acute ecotoxicity data for water and sediment samples was also included. It was determined that with certain limitations, PAH ratios can help determine the origin of hydrocarbons as being either petrogenic or pyrolytic. However, alkylated PAH homologues and parent compounds such as dibenzothiophene and perylene give more precise interpretation of the data. 30 refs., 9 tabs., 11 figs

    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.

    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.

    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

    2004-02-01

    We study the Brazilian Popular Music in a network perspective. We call the Brazilian Popular Music Network, BPMN, the graph where the vertices are the song writers and the links are determined by the existence of at least a common singer. The linking degree distribution of such graph shows power law and exponential regions. The exponent of the power law is compatible with the values obtained by the evolving network algorithms seen in the literature. The average path length of the BPMN is similar to the correspondent random graph, its clustering coefficient, however, is significantly larger. These results indicate that the BPMN forms a small-world network.

  3. Applied risk analysis to the future Brazilian electricity generation matrix

    Maues, Jair; Fernandez, Eloi; Correa, Antonio

    2010-09-15

    This study compares energy conversion systems for the generation of electrical power, with an emphasis on the Brazilian energy matrix. The financial model applied in this comparison is based on the Portfolio Theory, developed by Harry Markowitz. The risk-return ratio related to the electrical generation mix predicted in the National Energy Plan - 2030, published in 2006 by the Brazilian Energy Research Office, is evaluated. The increase of non-traditional renewable energy in this expected electrical generating mix, specifically, residues of sugar cane plantations and wind energy, reduce not only the risk but also the average cost of the kilowatt-hour generated.

  9. 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

    Full Text Available ABSTRACT 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.

  12. Status of the implementation of Brazilian National Repository

    International Nuclear Information System (INIS)

    In Brazil, the use of nuclear energy and radioisotopes is increasing and it already justifies the construction of a national repository for radioactive wastes of low and intermediate-level. The Brazilian National Commission for Nuclear Energy (CNEN) is legally responsible for designing and constructing intermediate and final storages for radioactive wastes generated in all Country, in accordance to Federal Law No. 10308. Additionally, the Brazilian Environmental Regulator (IBAMA) lately is imposing to the implementation of new nuclear installations (e.g. Angra 3 NPP and Brazilian Multipurpose Reactor) that the National Repository should be in construction, before the start-up of those ones. In November 2009, the RBMN Project Charter was signed. The RBMN Project aims at the implantation of a National Repository to dispose the radioactive wastes of low- and intermediate-level. Some aspects about the Repository construction are very challenging, mainly due to the licensing process, which will be made for two different regulatory bodies, nuclear and environmental. The main achievements obtained till now are the establishment of the current Brazilian radioactive waste inventory, the conceptual design and the selection of candidate sites for the repository.

  19. Brazilian safety standard for fire protection in nuclear power plants

    International Nuclear Information System (INIS)

    During licensing and surveillance of nuclear power plants the Comissao Nacional de Energia Nuclear of Brazil adopted IAEA Safety Series No. 50-SG-D2 as the basic regulatory document for fire protection. In the Angra I nuclear power plant, which was designed in the United States of America, the BTP 9.5-1 guidelines (revision 2, including Appendix R to 10 CFR, Part 50) were used in support, and in Angra II, which was designed in the Federal Republic of Germany, several Federal German standards were adopted. Because these guidelines, and some of the requirements therein, do not always agree with Brazilian law and site characteristics, it was decided to produce Safety Standard NE-2.03. It is based on Safety Series No. 50-SG-D2 and BTP 9.5-1, since they contain specific approaches to fire protection in nuclear power plants. Where any disagreement with Federal German and Brazilian standards occurred, a comprehensive engineering analysis was made in order to solve these problems without compromising plant safety. All the relevant aspects of the Brazilian Safety Standard are outlined. Also discussed are the modifications which had to be made to the guidelines and their requirements so that they are in accordance with Brazilian law and the site characteristics. (author). 3 refs

    The biodiversity of the Amazon forest is undoubtedly rich; hence there is considerable variety of plant fibers regarding their morphological, chemical and structural properties. The legal exploration of the Brazilian Amazon is based on sustainable management techniques, but the generation of a relevant amount of plant wastes still cant be avoided. The correct destination of such materials is a challenge that Brazilian companies have to face. In this context, the National Council of Science and Technology (CNPq) promoted the creation of investigation nets on sustainability of Brazilian agribusiness. The Brazilian Net on Lignocellulosic Composites and Nanocomposites was then created, with partnership between several national and international research institutions. Until the moment, the results showed that Amazon plant fibers that are discarded as residues have great potential to nanofiber production. Nanopapers with considerable high mechanical and physical strength, proper opacity and great crystalline index were produced by using a clean and simple mechanical method. Those materials are candidates to several uses such as packaging, substrates transparent conductive films, gas barrier films, solar cells and e-papers.

    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. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. Conclusion On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years. PMID:24675917

    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.

    The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for Brazilian development. In this mini-review we introduce what mangroves are and why they are so important. We give a brief overview of the microbial diversity found in mangrove sediments and then focus on diversity studies from Brazilian mangroves. We highlight the breadth and depth of knowledge about mangrove microbial communities gained from studying Brazilian mangroves. We report on the exciting findings of molecular microbial ecology methods that have been very successfully applied to study bacterial communities. We note that there have been fewer studies that focus on fungal communities and that fungal diversity studies deserve more attention. The review ends with a look at how a combination of new molecular biology methods and isolation studies are being developed to monitor and conserve mangrove ecosystems and their associated microbial communities. These recent studies are having a global impact and we hope they will help to protect and re-establish mangrove ecosystems. PMID:24031949

    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

  14. PERSPECTIVE: Learning from the Brazilian biofuel experience

    Science.gov (United States)

    Wang, Michael

    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

    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. PMID:26910551

    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.

  19. Brazilian nuclear renaissance in a sustainable development scenario - 097

    International Nuclear Information System (INIS)

    Brazil generated 326 TWh of hydroelectric power in 2005, accounting for ∼81% of the electricity production for that year. The 2005 to 2030 projections for the Brazilian development indicate growths from 2,020 kWh to 4,380 kWh in the per capita electricity consumption and from US$4,300 to US$8,950 in the per capita GDP (in market exchange rate and 2005 US$). The consumption of electricity is to grow from 375 TWh in 2005 to 1,030 TWh in 2030. In simple view and without considerations of aspects related with energy efficiency, this growth means 1.8 times the generation capacity of the 20. century should be built along of 25 years of the 21. century. The Brazilian electricity generation will demand all primary sources to meet the foreseen growth of the electricity consumption. As economical, safe and clean primary energy source for electricity generation, the nuclear energy is one option capable of large-scale and short-term deployment in the Brazilian growth of the electricity consumption. The contribution of nuclear generation in the electricity consumption should evolve from the current 2.6% for amounts over 5% in 2030. The perspective of the Brazilian nuclear sector is evolving to be resumed and present an opportunity for pooling and rationalizing the available skills - technical, cultural and human. The role of business opportunities and the future demands in the value chain of nuclear activities are summarized in this document. Institutions of R and D and Brazilian universities play an important role for the formation of new demanded knowledge and human resources. (authors)

  20. Trust within Brazilian New Economy Organizations: an Empirical Investigation of Gender Effects Benchmarked on Brazilian Old Economy Organizations

    2009-07-01

    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.

    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.

  2. Brazilian system for NPP personnel training

    International Nuclear Information System (INIS)

    part of the maintenance training center. Computers and audio-visual aids are available. There are two categories of nuclear power plant personnel which are regulated by CNEN: Licensed personnel (Senior Reactor Operators - SRO and Reactor Operators - RO) and Health Physics Supervisors. For these two categories, CNEN sets up rules and regulations which require approval of training programs and certificate them through independent written and oral examinations. All training activities related to these personnel are reviewed by CNEN. Licensed operators are required biannual retraining courses and their licenses are renewed every two years, after the applied programs are evaluated and approved by CNEN . Their requalification training programs, with utilization of full-scope simulators, however, are performed every year, at training centers located in the U.S. and Spain. ELETRONUCLEAR continuously exchanges information with international organizations such as IAEA, INPO, WANO and VGB, in areas of operational experience and guidelines related to training activities. raining Department provides an average of 24.000 mht (man-hour trained) per month, for the several departments of ELETRONUCLEAR and external organizations. It means 8% of total work force dedicated permanently to training programmes. Presently, there are some important issues influencing planning of training activities. During the last two years, production of electrical energy in Brazil could not follow its increasing consumption. Due to this problem, the Federal Government has decided to incentive an expansion of thermal energy production system, which is based mostly on large availability of natural gas in South America. This emerging market has recruited an expressive number of nuclear Personnel, Vienna (AT) salaries usually are higher in comparison with the nuclear market. Additionally, nuclear workers can retire after 25 years of work, following Brazilian legislation. These two aspects cause a expressive

    2016-01-01

    Full Text Available In heterodox literature, the industrial sector is considered strategic for economic development. Consequently, reducing the contribution of this sector in the production of the country before it has reached the stage of economic maturity, affects the productive dynamics and slow technical progress. The appreciation of the real exchange rate is seen as one of the factors responsible for the reduction of the external competitiveness of Brazilian manufactures, and this exchange rate valuation may be occurring due to the differences between domestic and international interest rates. Given this context, the aim of this study is to evaluate the impact of changes in the monetary and exchange rate policy and in the composition of the total exports on the performance of the Brazilian economy using a structuralist model. The results reinforce the importance of the manufacturing sector to economic growth, especially in a competitive exchange rate environment.

    Epilepsy is a frequent condition in the world. Recently a study in Brazil showed prevalence of 18/1000 inhabitants in São José do Rio Preto, São Paulo State. In the last decade, new therapeutic options were discovered or developed. The main therapeutic decision method is based on randomized clinical trials. This method represents the higher level of evidence. However, even these studies have limitations and in some cases the treatment of choice remains controversial. In these instances, the epilepsy experts' opinions become helpful. In 2001 a similar study had been conducted in USA. The aim of this study is to create guidelines for epilepsy treatment based on the opinion of the Brazilian experts. These guidelines can be used to create manuals and strategies for the treatment of some epileptic syndromes according to Brazilian experts. As compared to the North-American guidelines our study better reflects the resources available in our country. PMID:14762617

    This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information. PMID:23099762

    2009-07-01

    Hydrogen is a promising energy carrier, which potentially could replace the fossil fuels used in the transportation and distributed energy sector of Brazilian economy. Fossil fuels are polluting by carbogenic emissions from their combustion, being so co-responsible for present global warming. However, no large scale, cost-effective, environmentally non-carbogenic hydrogen production process is currently available for commercialization. There are feasible possibilities to use electrolysis as one of the main sources of hydrogen, especially thinking on combination with renewable sources of energy, mainly eolic and solar. In this work some perspectives for Brazilian energy context is presented, where electrolysis combined with renewable power source and fuel cell power generation would be a good basis to improve the distributed energy supply for remote areas, where the electricity grid is not present or is deficient.

  8. Stolen beauty: gender, aesthetics and embodiment in Brazilian drama

    Directory of Open Access Journals (Sweden)

    Heloisa Pontes

    2008-01-01

    Full Text Available Drawing from a broader research on gender inflections in the Brazilian intellectual field and in Brazilian drama, between 1940 and 1968, the article discusses the relations between aesthetics and gender, and their implications on the careers of actresses Cacilda Becker, Maria Della Costa, Tônia Carrero and Cleyde Yáconis. According to testimony of those who saw her perform on stage, Cacilda was never hampered by her less favorable physical attributes. The hypothesis is that this is due to the cunning tricks of the conventions of dramatic arts that allow the dodging of social, gender and physical constraints. Widely evoked by the media to portrait, underline or diminish women under its focus, beauty rarely features as a relevant dimension in the analysis of female trajectories. Hence the interest in discussing the subject through its refraction on the process of social construction of artistic careers.

    Full Text Available Job stress can negatively affect the health of employees. As such, the investigation of its characteristics in different professional categories is relevant. The aim in this study was to analyze the predictive power of seven stressors (decision latitude, psychological demands at work, physical demands at work, social support from colleagues, ergonomic stressors, relationships with clients, job insecurity for job dissatisfaction, depression and psychosomatic problems in a sample of 702 Brazilian lawyers. The data were collected using a Brazilian version of the Job Content Questionnaire (JCQ. The results showed that decision latitude and social support were the main negative predictors of stress, while psychological demands and job insecurity were its main positive predictors. These results are discussed in the light of the demand-support-control model, which was used as a framework for the research.

    This study investigates the latest research on the profile of the Brazilian prison population, its demography and current laws and regulations. It aims in the direction of ensuring the human right to health. Brazilian prison system is a complex universe in which state and federal criminal contexts keep more than 607,000 people in custody. This population is composed of 75% of young and black people, 67% poorly educated and 41% are pre-trial detainees, living in overcrowded prisons and architecturally vandalized, with population growth of around 575% in 24 years, making this environment a major focus of production of diseases. The prison becomes the object of differentiated intervention by public bodies linked to the executive and the judiciary - it is worth remarking that the data show the high level of inequalities and health vulnerabilities among the prison population, whose needs involve a set of cross-sector of transverse public policies actions towards penal execution.

    2014-01-01

    Full Text Available This paper presents an efficiency analysis of Brazilian bulk terminals built upon the conjoint use of Data Envelopment Analysis and the bootstrapping technique. Confidence intervals and bias corrected central estimates were used as cornerstone tools, not only to test for significant differences on efficiency scores and their reciprocals, but also on returns to scale indicators provided by different DEA models. The results of the study suggest that most Brazilian bulk terminals present increasing returns-to-scale, that is, they are too small in size comparatively to the tasks performed, indicating a capacity shortfall. Results also suggest paths for improving efficiency levels in a scenario of low investments and capacity constraints: privatization and cargo specialization. A final contribution to the literature lays on the development a simple methodology to assess returns-to-scale based on bootstrap results.

    Full Text Available This paper investigates changes in long-term operational and financial performance for a sample of Brazilian companies made initial public offerings (IPO's shares, in the period 2002-2008. This period showed a historically high number of IPOs, a heavily discontinued phenomenon with the international financial crisis of 2008. As performance measures were chosen six financial indicators usually adopted in the literature in periods of three years pre-IPO, year of listing and three years post-IPO. The indicators evaluated were size, growth rate, profitability, financial leverage, investment level and investment rate. The results show evidence that, on average, there were statistically significant improvements in size, profitability, investment level and investment rate.

    Full Text Available This paper investigates the determinants of trade credit supply by Brazilian publicly traded companies between the years of 2005 and 2008. International literature (both theoretical and empirical documents that the main determinants of trade credit supply are the size of the firm and the size of its debt. Both indicate that the availability of resources to the firm is an important factor for the supply of trade credit. In addition, the literature confirms strategic uses of trade credit such as those for price discrimination purposes. The results obtained using a sample of 157 Brazilian companies do not support that size and indebtedness are relevant determinants for trade credit supply, but they confirm the supply of trade credit as a strategic tool for the firms. Additionally we observed a significant decrease in trade credit supply in 2008, the year in which a severe international financial crisis took place.

  17. Brazilian nuclear politics in the context of contemporary international relations

    International Nuclear Information System (INIS)

    The present dissertation analyses the retaking of the debate over Brazilian nuclear Program's recovery by Luis Inacio Lula da Silva government, based on the defense of the utilization of an already acquired technology of its own to enrich uranium. In spite of the intrinsic duality on this subject and having in mind the pacific ends concerning the utilization of such technology by Brazil, the hypothesis sustained in this work is that the Program's defense is considered a strategy of sovereign international insertion with relative autonomy and an instrument of national valorization against other powers. In order to verify the hypothesis outlined above, we will analyse the actual government, comparing it to, two other moments in Brazilian History in which the nuclear issue also acquired preponderance on the national agenda, namely, Geisel and Sarney governments. Although these three moments differ in relation to their internal political regime, our goal is to identify their similarities. (author)

    2016-06-01

    Full Text Available ABSTRACT This research analyses how the interaction between strategy capabilities, strategy types, strategy formulation quality and implementation capability affect organizational performance in Brazilian textiles companies. This article proposes and tests a conceptual framework, using a structural equation modeling of a set of 211 valid questionnaires on Brazilian textiles firms. The results support links between focus strategy and marketing capabilities, and between cost leadership strategy and management capabilities. However, the relationship between technologic capabilities and differentiation strategy was not statistically significant. The existence of an inter-relationship between generic strategies of focus, cost leadership and differentiation indicates the use of combined strategies. Concerning the firms' financial performance, the results show that management capability and market performance have a statistically significant relationship with financial performance.

    Full Text Available OBJECTIVE: To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals. STUDY DESIGN: Women delivered of a singleton birth (n = 8228, recruited from five public level III maternities (April 2005-August 2006 during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status as Portuguese (n = 7908, non-Portuguese European (n = 84, African (n = 77 and Brazilian (n = 159. A Poisson model was used to evaluate the association between country of birth and cesarean section that was measured by adjusted prevalence ratio (PR and respective 95% confidence intervals (95%CI. RESULTS: The cesarean section rate varied from 32.1% in non-Portuguese European to 48.4% in Brazilian women (p = 0.008. After adjustment for potential confounders and compared to Portuguese women as a reference, Brazilian women presented significantly higher prevalence of cesarean section (PR = 1.26; 95%CI: 1.08-1.47. The effect was more evident among multiparous women (PR = 1.39; 95%CI: 1.12-1.73 and it was observed when cesarean section was performed either before labor (PR = 1.43; 95%CI: 0.99-2.06 or during labor (PR = 1.30; 95%CI: 1.07-1.58. CONCLUSIONS: The rate of cesarean section was significantly higher among Brazilian women and it was independent of the presence of any known risk factors or usual clinical indications, suggesting that cultural background influences the mode of delivery overcoming the expected standard of care and outcomes in public health services.

    International Nuclear Information System (INIS)

    The paper presents the Brazilian Nuclear Energy Program: its development until the present stage, as well as the organizations and the distribution of responsibilities involved in its execution at the present time. The nuclear power policy is established at the Presidency of the Republic and is planned, executed and controlled through the Ministry of Mines and Energy. Directly subject to the Ministry is the Brazilian Nuclear Energy Commission (CNEN), which has regulatory, standardization, licensing, planning and surveillance functions. The nuclear fundamental research and manpower formation are also under CNEN responsibility. Also subject to the Ministry are two companies responsible for the execution of the Programme: the Centrais Eletricas Brasileiras S.A. - ELETROBRAS, which advises on the granting of permits for the construction and operation of nuclear power plants, and the Empresas Nucleares Brasileiras S.A. - NUCLEBRAS, which holds the monopoly of the nuclear fuel cycle in the country, designs and builds nuclear power plants and provides assistance to the electric utilities as well as promotes the participation of the Brazilian industry in the nuclear field. Besides describing the new distribution of regulatory functions given by law to the CNEN, this paper gives special emphasis to the large industrial complex which is in the process of being established with the setting-up of the many NUCLEBRAS subsidiaries in joint-venture with German firms in the nuclear field, as a consequence of the Industrial Cooperation between Brazil and the Federal Republic of Germany in the Field of the Peaceful Uses of Nuclear Energy signed between the two countries on June 27, 1975. The programs for these subsidiaries are presented and their participation in the Brazilian Nuclear Energy Programme is discussed.

Unions tend to reduce profitability, whereas the relationship between union density and productivity, employment and average wages seems to be concave. These performance indicators first rise with union density up to a certain density level (usually about 50 percent) and then start to decline. These resu...

  12. Complex organizations: the case of the Brazilian nuclear sector

    International Nuclear Information System (INIS)

    The resumption of the Brazilian Nuclear Program (BNP), in the proposed size and after 20 years of paralysis, requires profound changes in the current organizational modeling of the national nuclear industry. The effectiveness of any process of organizational change is limited to three factors. The theoretical bottleneck happens when you do not know enough about a phenomenon in order to effect the desired changes. The resource bottleneck occurs when knowledge may be available to change people's behavior but the funds necessary for implementation may be lacking. The organizational bottleneck emerges when there are knowledge and resources to solve a problem, but may not able to organize the resources in order to carry out the problem-solving effort. In the case of resumption of BNP seems clear that there is the knowledge of what is needed to make policy and the intention to allocate the necessary resources. But the question is the following: the current organizational model of the Brazilian nuclear sector is consistent with the goals laid down in the scenario of resumption of BNP? That is, is there organizational ability to leverage a program of the size proposed for the nuclear area? Find answers to these questions is crucial, because the organizational model of the Brazilian nuclear sector consists of elements involving a complex interorganizational system. Thus, this article is to examine the appropriateness of the current organizational modeling of the Brazilian nuclear sector to current demands of society. As a result, the article aims to propose recommendations for a remodeling of the nuclear sector, taking into account the current national and international scenarios of nuclear energy. (author)

    The genus Kogia, which comprises only two extant species, Kogia sima and Kogia breviceps, represents one of the least known groups of cetaceans in the global ocean. In some coastal regions, however, stranding events of these species have been relatively common over the last decades. Stranding provides the opportunity to investigate the biology of these cetaceans and to explore the epidemiological aspects associated with the mortality of the organisms found on the beach. A number of disturbances (including pelagic fisheries, chemical pollution, boat strikes, and noise pollution) have been confirmed to pose a particular threat to the Kogia species. However, no study has yet investigated potential relationships between environmental conditions and stranding events. Here we analyse how a collection of environmental, physical, and biological variables, such as wind, sea surface temperature (SST), water depth, and chlorophyll-a, correlate to Kogia stranding events along the Brazilian coast. The results of our statistical analyses suggest that K. sima is more likely found in warm tropical waters, which provide an explanation for the high frequency of stranding in northeastern Brazilian coast. In contrast, K. breviceps appears to have a preference for temperate and productive waters. Wind speed results to be also an important factor for predicting Kogia strandings in Brazilian coast. Additionally, literature information in combination with our own data and analyses of stomach contents confirms that oceanic cephalopods constitute the primary nutritional source of both Kogia species. By using the available information as a qualitative proxy for habitat preference and feeding ecology, our study provides a novel and comprehensive assessment of Kogia stranding data in relation to environmental conditions along the Brazilian coast.

    Full Text Available The Brazilian preference shares, in general, except when they present specific features, such as mandatory redemption and cumulative dividends, meet the accounting definition of equity instruments. However, the scientific literature believes that those shares that do not have discretion to avoid the delivery of cash must be classified as financial liabilities. In a context in which remain differences of understanding of their proper accounting treatment, the following question arises: preferred shares of Brazilian companies are being recognized in the financial statements in accordance with the theoretical and normative precepts? Thus, the aim of this study is to verify if the preference shares of Brazilian companies have been recognized in the financial statements for according to the scientific literature and accounting standards. Through content analysis, we analyzed the information of 157 companies listed on BM&FBOVESPA. The results show that 155 companies classify its preference shares as equity instruments and two as financial liabilities. These two companies, as well as 149 of those which qualify as equity instruments, are treating them properly in its accounting. The other six companies should present its preference shares as liabilities, given the absence of discretion to avoid cash delivery, feature present in financial liabilities, unlike equity instruments. It is noticed that, unlike what happens, for instance, in the US market, it is not possible to classify all Brazilian preference shares as a financial liability, since, in Brazil , they are used in different legal format of those widely found in that market. Moreover, almost all of the analyzed shares have essential features for classification as equity instruments. Hence, the importance of analysis of the economic essence of each instrument, thus, enabling the appropriate accounting treatment in the financial statements.

    2013-03-01

    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.

Out of them, 10 published articles having the theme earning management in the title, abstract or keywords. The 32 identified articles were submitted to content analysis and then the data were presented from the perspective of social networks. The survey results show that: the authors and their social networks of production originates mostly from Universidade de São Paulo (USP; the most researched theme was the methods or means to conduct earnings management, and accruals measurement models, with emphasis on Kang and Sivaramakrishnan Model; the descriptive research, based on document and quantitative approach were the most commonly used forms in the articles researched. It is noteworthy that structural gaps are the topics, such as compensation plans, political costs and earnings management in different contractual environments. The research results can contribute to academia to highlight some features of the earnings management theme and its researchers, in the field of publications in Brazilian accounting journals.

    Full Text Available Deforestation in the Brazilian Amazon has dropped substantially after a peak of over 27 thousand square kilometers in 2004. Starting in 2008, the Brazilian Ministry of the Environment has regularly published blacklists of critical districts with high annual forest loss. Farms in blacklisted districts face additional administrative hurdles to obtain authorization for clearing forests. In this paper we add to the existing literature on evaluating the Brazilian anti-deforestation policies by specifically quantifying the impact of blacklisting on deforestation. We first use spatial matching techniques using a set of covariates that includes official blacklisting criteria to identify control districts. We then explore the effect of blacklisting on change in deforestation in double difference regressions with panel data covering the period from 2002 to 2012. Multiple robustness checks are conducted including an analysis of potential causal mechanisms behind the success of the blacklist. We find that the blacklist has considerably reduced deforestation in the affected districts even after controlling for the potential mechanism effects of field-based enforcement, environmental registration campaigns, and rural credit.

    The hematology of wild and captive animals is essential for obtaining details about species and represents a simple method of diagnosing disease and determining prognosis. Few studies have described the morphology of chelonian blood cells, which are more common in sea and freshwater turtle species. Thus, in order to further our understanding and recognition of different chelonian cells types, the present study aimed to describe blood cells from the two species of Brazilian tortoises, Chelonoidis carbonarius and C. denticulatus. Cytochemical analysis of tortoise blood tissue with Panótico®, made it possible to describe all the of the chelonian cell types (with the exception of thrombocytes): erythrocytes, agranular leukocytes (monocytes and lymphocytes), and granular leukocytes (eosinophils, heterophils, basophils, and azurophils). These data are of high importance for establishing hematological profiles of Brazilian tortoises and reptiles. Therefore, based on our results and on comparative analyses with data from the literature for other reptile species, we can conclude that the blood cells described for Brazilian tortoises are found in all species of reptiles that have been analyzed thus far, and may be characterized and used as a comparative parameter between different groups to evaluate the health status of these animals.

    There are few studies involving the detection of Aichivirus B in cattle herds worldwide, and this virus has never been diagnosed in South America. This study evaluated 222 diarrhoeic faecal samples from four Brazilian geographical regions (South, Southeast, Midwest, and North), collected between February 2010 to May 2012. To evaluate the frequency of occurrence in different types of livestock, samples from beef (n = 105) and dairy (n = 117) cattle herds were evaluated. To determine the category of animals more susceptible to infection, the sampling included samples from calves (n = 182) and adults animals (n = 40). The 216 bp fragment of the Aichivirus RdRp gene was amplified by a RT-PCR assay in 18.2 % (40/222) of the samples evaluated in both beef and dairy cattle animals. The highest (P Aichivirus B was found in calves. The nucleotide sequencing analysis showed that the Brazilian Aichivirus B strains clustered in a distinct branch in the phylogenetic tree of the European and Asiatic strains. This is the first description of Aichivirus B infection in Brazilian cattle herds. PMID:24590582

    Full Text Available Gleison V Duarte,1 Larissa Porto-Silva,2 Maria de Fátima Paim de Oliveira1 1Dermatology Department, Federal University of Bahia, Salvador, 2Escola Bahiana de Medicina e Saúde Pública, Salvador, BA, Brazil Abstract: Psoriasis is a chronic immune-mediated systemic disease that is influenced by genetic and environmental factors, is associated with comorbidities, and has a negative impact on the quality of life of affected individuals. The prevalence of psoriasis varies among different ethnic groups, but this topic has not been studied in Brazil to date. In this review, we evaluate the epidemiology and treatment of psoriasis from a Brazilian perspective. We focused on studies that involved Brazilian subjects. The prevalence of psoriasis in Brazil is estimated to be 2.5%, but no population study has been performed previously. Environmental factors, such as tropical climate, in association with genetic factors, such as miscegenation, may exert a beneficial impact on the course and frequency of psoriasis in Brazil. A number of studies have advanced our understanding of the cardiovascular, ophthalmic, and oral comorbidities that are associated with psoriasis. Concerns about biological therapy, such as endemic leprosy, human T-cell lymphotropic virus (HTLV, and tuberculosis infections, are discussed. The nonavailability of treatment options for psoriasis in the public health system contradicts the Brazilian Society of Dermatology guidelines, stimulating the judicialization of access to medicines in psoriasis care. Keywords: psoriasis, epidemiology, comorbidities, health services accessibility, health care disparities, insurance, health care costs

  15. The stochastic effects on the Brazilian Electrical Sector

    International Nuclear Information System (INIS)

    The size and characteristics of the Brazilian Electrical Sector (BES) are unique. The system includes a large-scale hydrothermal power system with many hydroelectric plants and multiple owners. Due to the historical harnessing of natural resources, the National Interconnected System (NIS) was developed outside of the economic scale of the BES. The central components of the NIS enable energy generated in any part of Brazil to be consumed in distant regions, considering certain technical configurations. This interconnection results in a large-scale complex system and is controlled by robust computational models, used to support the planning and operation of the NIS. This study presents a different vision of the SEB, demonstrating the intrinsic relationship between hydrological stochasticity and the activities executed by the system, which is an important sector of the infrastructure in Brazil. The simulation of energy scenarios is crucial to the optimal manner to operate the sector and to supporting decisions about whether expansion is necessary, thus, avoiding unnecessary costs and/or losses. These scenarios are an imposing factor in the determination of the spot cost of electrical energy, given that the simulated quantities of water in the reservoirs are one of the determinants for the short-term energy price. - Highlights: • The relationship between the hydrological regimes and the energy policy and planning in Brazil; • An overview about the stochastic effects on the Brazilian Electrical Sector; • The stochasticity associated with the Brazilian electrical planning; • The importance of hydro resources management for energy generation in Brazil;

  16. The challenge of energy poverty: Brazilian case study

    International Nuclear Information System (INIS)

    In recent years successive Brazilian governments have actively pursued economic and social policies aimed at reducing poverty and promoting social equality and inclusion. In the field of energy, this has meant introducing and implementing programs aimed at expanding the supply of safe and reliable energy to the poorest sectors of Brazilian society, including those living in remote rural areas. This paper draws attention on the findings of extensive field research to evaluate the impact of rural electrification on energy poverty in the context of government policies aimed at promoting energy equity. The authors re-examine the concept of an energy poverty line, seeking to fine tune its application to Brazilian social and economic realities, and then apply an analytical framework (Lorenz Curve, Gap Poverty, Gap Quadratic, Gini Coefficient and Sen Index) to evaluate the effectiveness of recent efforts in Brazil to expand access to electricity. One of the main conclusions of this study is that is that rural electrification leads to a significant reduction of the energy poverty level and a consequent improvement in energy equity. -Research highlights: → The access to electricity led to a marked change in the reality of the researched population. → Energy poverty and energy inequality were reduced significantly. → The strategy of combating energy poverty through programs of rural electrification is efficient.

    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 BACKGROUND: Oral care is a fundamental procedure for the success of the hematopoietic stem cell transplantation, particularly regarding the control of oral infectious diseases. Information about oral care protocols and the inclusion of dental professionals in transplantation medical staff is poorly known. OBJECTIVE: The aim of this study was to carry out a survey about the protocols of Brazilian dental professionals with regard to oral care of HSCT patients. METHODS: A questionnaire was mailed to 36 Brazilian transplant centers with questions about basic oral care protocols, the indication of specific mouthwashes, antibiotic therapy regimens, laser therapy, and treatment of oral mucositis and graft-versus-host disease. All the respondent centers (n = 12 have dentists as members of the HSCT medical staff. RESULTS: The majority indicate non-alcoholic chlorhexidine (n = 9; 75.0% and sodium bicarbonate (n = 5; 41.7% as routine mouthwashes. Laser therapy was frequently indicated (n= 9; 75.0%, mainly in the prevention of oral mucositis and in oral pain control. In the post-transplant period, antibiotic therapy was only indicated for invasive dental treatments (n= 8; 66.7%. Several treatments for graft-versus-host disease were mentioned without a trend towards establishing a standard protocol. CONCLUSION: Basic oral care constitutes regular assessment in the routine treatment of hematopoietic stem cell transplantation patients in Brazilian centers.

  19. Energy-efficiency standards for electric motors in Brazilian industry

    International Nuclear Information System (INIS)

    The first regulation of the 'Energy Efficient Act' for electric motors, launched in 2002, established two sets of minimum efficiency performance standards (MEPS), for 'standard' (mandatory) and 'high efficiency' (voluntary) motors. An updated regulation, from the end of 2005 (Edict 553/2005), established the previous high-efficiency MEPS as mandatory for all motors in the Brazilian market. This paper analyses the consequences of this new regulation, which is foreseen to take effect in 2010. These new Brazilian MEPS are compatible with those implemented in other countries. The cost-benefit analysis, considered for different scenarios for industrial consumers, showed that motor substitution (from standard to high efficiency) is generally advantageous. A sample of nine thousand industrial motors has been used, with measured operation in actual conditions, to analyze the investment cost-benefit in three different scenarios. This analysis also demonstrated the benefit of motor substitution, with an average MWh cost from 20 to 35 US$, and with only a few substitutions presenting an unfavorable cost-benefit relationship to the user. We assess that Edict 553 avoided construction of 350 MW of hydroelectric capacity. Nevertheless, since the cost of conserved energy for this energy-saving measure is generally below the marginal cost of expansion of the Brazilian electric system, we propose mechanisms to share investment costs among the society as a whole, including demand-side bidding

    Despite the improvement of the lives of Brazilians, still persists a panorama of iniquities in health in Brazil. This ecological study evaluated the relationship of socioeconomic conditions and public health policy with oral health conditions in Brazilian capitals. Factor analysis was performed with the socioeconomic indicators, revealing two common factors: economic deprivation and socio-sanitary condition. Then, was executed multiple linear regression analysis for the oral health indicators (average DMFT 12 years, mean missing teeth and rate of decay of free population) with two factors in common and fluoridation of water supply. Multiple linear regression analysis to the DMFT of the capitals was estimated by the socio-sanitary conditions and fluoridation, adjusted by economic deprivation; whereas the model for the average missing teeth was estimated only for flu-oridation and economic deprivation, and finally, the model for the rate of caries-free population in the Brazilian capitals was estimated by economic and sociosanitary condition set by fluoridated water supplies. Therefore, the results indicate the need for social actions that impact on people's living conditions to reduce tooth decay. PMID:26221819
