    Full Text Available 17 of 20 adult sera from the Amapa region of Brazil were active in the inhibition of P. falciparum sporozoite invasion (ISI assay which has been correlated with protective antibodies. In contrast 11 sera were positive in IFA tests and 6 were positive in CSP tests. These results suggest that the ISI assay will be useful for evaluating naturally acquired protective anti-sporozoite antibodies in endemic areas, particularly during vaccine efficacy studies using sporozoite-based vaccines.

    In this work it is presented a survey on total mercury determination by a radiochemical method in sediment and soil samples from two regions, in the state of Amapa: Serra do Navio (background area) and Vila Nova river basin (gold mining area). The method consisted in leaching of the irradiated samples with acqua regia in a Parr bomb, and heating in microwave oven, for one minute. Then the solvent extraction technique was applied, using bismuth diethyldithiocarbamate (Bi(DDC){sub 3}) as extractant agent. The organic phase, containing {sup 197}Hg and {sup 203}Hg radioisotopes, was measured in a gamma spectrometer with hyper pure Ge detector. This method eliminated the interference of the 279.54 keV photopeak of {sup 75}Se on 279.2 keV photopeak of {sup 203}Hg, besides improving counting statistics of both Hg radioisotopes. The elements As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, Ho, K, La, Lu, Mg, Mn, Na, Nd, Rb, Sb, Sc, Se, Sm, Ta, Tb, Th, Ti, U, V, W, Yb, Zn and Zr were also determined by the instrumental neutron activation analysis. Two irradiation series were carried out to quantify these elements in soil and sediment samples; a short term irradiation allowed to evaluate Mg, Mn, Na, Ti and V levels, and by long term irradiation, the other elements were determined. Precision and accuracy of radiochemical procedure were verified by means of analysis of the reference materials Buffalo River Sediment and Lake Sediment, for sediments and GXR-5, for soils. For the instrumental analysis, the reference materials Buffalo River Sediment, Soil 7, JB-1 and Oyster Tissue were used. The samples were also submitted to X ray diffraction, in Instituto de Geoscience-USP, to observe mercury behaviour with mineralogy. Aluminium concentration was determined by X ray fluorescence method, in the Department of Materials, IPEN/CNEN-SP, making possible enrichment factor calculation so that mercurial contamination in the gold mining area (Vila Nova river basin) could be evaluated.

    A few outcrops and strong weathering conditions prevail in the region of the Vila Nova Greenstone Belt in the southeastern Amapa (Brazil). This paper describes the use of airborne geophysical data for geological and structural analysis during geological mapping. This integration aims to improve the geological and tectonic understanding of this portion of the Amazonian Craton. The magnetometric and gamma-spectrometric qualitative interpretation of the images took place in a Geographic Information System (GIS) environment. Recognition of magnetometric and gamma-ray spectrometric units present in the study area was based on the hierarchical classification of polygons outlined by visual interpretation. The major geological domains and the structural patterns were defined by integration of geophysical data, geological mapping and petrographic analysis. The results allowed the recognition of Archean basement rocks composed of orthogneisses and granitoids of the Tumucumaque Complex, the metavolcano-sedimentary rocks of the Vila Nova Complex and Paleoproterozoic granite massifs. The integration of geophysical and field data resulted in the increase of the geological mapping definition, highlighting the importance of this methodology for recognition of complex structural and lithological fabrics in areas of difficult access and scarce fresh rock outcrops.

    Mercury analysis of human head hair has been of much concern in connection with mercury contamination deriving from gold exploration activities. Neutron activation analysis has been applied as a highly sensitive and accurate method. Total mercury is being determined in hair samples from populations from the regions of Serra do Navio, Tartarugalzinho and Vila Nova, in the Amapa State, Brazil. The reference materials IAEA - 085 and IAEA - 086 were also analysed. The range of total mercury analysis is o,21 - 18,84 ppm. These results show a possible contamination, comparing to a control group analysed. (author)

    The objective of the present work was to characterize two new Clay deposits (A and B) from the south region of Amapa state, aiming to establish their adequate uses as ceramic raw materials and to promote the potential of the ceramic industry in the region. Were prepared specimens by uniaxial pressing, being applied a two phase pressing of 13,4 MPa and 20 MPa, respectively. The samples were dried in an oven at 110 deg C, and submitted to burning at 850, 1000 and 1200 deg C. Were determined linear firing shrinkage, water absorption, apparent porosity and modulus of flexural modulus of rupture, as well as mineralogical evolution after burning. Finishing, the microstructure of the sintered clay at 1200 deg C was evaluated in a scanning electron microscope. The results showed that the clay A presented a better mechanical development, having a red coloration and, therefore, potential to the red ceramic industry. On the other hand, the clay B presented a light color, due to a low content of iron oxide and, therefore, having potential as refractory raw material. In general, one clay is suitable to be used in white ceramic and the other in red ceramic. (author)

    The north brazilian coastal region is submitted to the conjunction of three major forcing: 1) Atmospheric, related to the wind and precipitation regimen and controlling the climatic seasonality and the local rivers hydrology; 2) Oceanic, result of the general oceanic circulation (North Equatorial Current-NEC) and it modulation with the atmospheric forcing (North Brazilian Coastal Current reflection), and 3) Amazonic, which is a result of the sedimentary transport from Amazon river, being itself under the influence of the atmospheric and oceanic forcing. Their main characteristic are the proper periodicities and also variabilities expressed according multiples and differentiated scales of time and space, determining the structure and functioning of the coastal space, giving to the Amazon coast line a considerable environmental instability. The Amapa Coastal Plain shows important part of this environmental instability. Semidiurnal macro tides, strong currents and tidal bores acts over a low gradient coastal plain which evolutionary process are intrinsically related with tectonic and geological settings. Two main areas can be distinguished in this scenario. The first one is the Amapa Lakes Region, developed over meanders of ancient drainages building a mosaic of low relief forms, with varied shapes, linked throughout communication channels. Two lacustrine belts showing alignments with the main tectonic traces were recognized beginning at the internal limit of the coastal plain, flowing southeast through the Tabaco Creek until reach the Araguari River. In it way it conform the Occidental and Meridional Belts represented by shallow lakes, totally dependent of Tartarugal River discharge and surrounded by enormous areas of peat highly sensitive to fire during the regional low discharge. Light blue clays, peat and a package of tidal deposits with fluidization structures were recognized close to Araguari River, suggesting deposition during high sea level. The second area

    Full Text Available The study investigated the production and trade chain as well as aspects of the consumption of the medicinal latex from amapa tree (Parahancornia fasciculata in the municipalities of Belém and Ponta de Pedras, State of Pará, Brazil. Our goal was to shed light upon several aspects related to the management and use of the product, revealing its importance to the life of producers and consumers. The approach used was the 'production to consumption chain' through qualitative and quantitative research methods, including market survey, interviews with extractivists, traders and consumers, workshops, guided visits and forest inventories. The eight thousand litters of milk sold annually in the Belém markets benefit especially the poor people, to whom the use of the 'amapa milk' is secular. The revenue from the latex represents 42% of the total income from non timber forest products for the tappers. The large number of individuals and the J-shaped diameter distribution of trees suggest the possibility of its natural regeneration. The improvement of the tapping technique reveals that the extractivists have knowledge on the tree anatomy. The tradition in the use and management of amapa milk as well as the ecological characteristics of the species indicates a good potential for programs on its sustainable production.

    In this study, layered nanostructured Mn oxide, Ca-OL (octahedral layer), was obtained from Mn ores of Serra do Navio (Amapa, Brazil). The developed synthetic route used dissolution chemical processes, precipitation, ion exchange and hydrothermal treatment, respectively. The results showed the presence of DRX peaks in the position 12,5 and 25º (2 theta), confirming Mn oxide Na-birnessite-type structure (Na-OL-1) obtainment which transformed into Ca-buserite (Ca-OL-2) after Ca{sup 2+} ion exchange. Infrared spectroscopy (FTIR) bands of the MnO6 octahedrons Mn-O vibrational bond were identified in the range of 800 to 400 cm{sup -1} which confirmed the DRX data obtained. The Ca-OL-2 thermal behavior obtained by TG-DTA showed thermal stability above 850 deg C, thus exhibiting that products as ores can be transformed into Mn oxides nano layers with high thermal stability.

    Total Hg was determined in sediment, piscivorous fish and human hair from two similar lake areas in Amapa State, Brazilian Amazon: Duas Bocas Lake (DBL), influenced by Hg releases from gold mining; and Pracuuba Lake (PL), a pristine site 15 km to the north. In DBL, Hg profiles in sediments clearly documented the evolution of Hg pollution, and Hg was significantly higher in fish and human hair than in PL. {sup 203} Hg methylation rates in sediments and methylmercury proportions in fish suggest a high Hg bioavailability in both lakes. Average daily fish intake is approx. 200 g, and at DBL 95% of fish samples (N = 40) exceeded the 150 ng Hg g{sup -1} safety limit. Hg in human hair averaged 28 {mu}g g{sup -1} (N = 15), i.e. a level at which neurotoxic effects have been found. However, Hg was also high in the pristine PL, where 67-100% (N = 34) of the fish had levels that exceeded the safety limit, and 87% of hair samples (N = 15) had above 10 ng Hg g{sup -1}. In both areas, children and pregnant women should be advised to consume nonpiscivorous and/or small fish species. Hg levels should also be investigated in other areas of the Amapa coastal plain 30 refs, 5 figs, 1 tab

    Nowadays, insect control is usually carried out using chemical insecticides, but insect resistance and other negative side effects have prompted the search for alternatives. Biopesticides provide a positive alternative to synthetic pesticides because they have low impact on the environmental, low toxicity to humans and low costs among other advantages. This research was carried out to evaluate the activity of Parahancornia amapa (Huber) Ducke (Apocynaceae) lyophilized latex on the post embryonic development of Chrysomya megacephala (F.) (Diptera: Calliphoridae). Larvae treated with 1.0% latex showed a shorter post embryonic development period (larval, pupal and newly hatched larvae to adult); whereas larvae treated with 3.0% latex provoked a prolongation of these periods. Viability (53%) was also very low at the newly hatched larvae to adult period for larvae treated with 3.0% latex, indicating that latex from P. amapa at high concentrations could change C. megacephala post embryonic development.

    The main objective of this dissertation is to adapt the methodology of Strategic Environmental Assessment (SEA) to the case of ethanol fuel production in Brazil. The results are be utilized in decision-making processes as well as in the discussion on future tendencies of risks and opportunities regarding the development of ethanol as the principal renewable liquid fuel. Taking into account the international experiences of countries with a tradition in sectoral planning, SEA is found to be the instrument in public environmental management that can most adequately consider the environmental variable - beginning already at the planning stage of the ethanol industry, a necessity that has strongly unfolded itself following the deregulation of the sector in Brazil. The conflicts that may emerge from large ethanol production surpluses for export are also identified through the application of specifically designed indicators. (author)

    The Sterile Insect Technique is a method of pest control allowed in Integrated Pest Management programs in fruit growing, where sterile insects released compete in mate process against fertile wild ones, generating a gradative population reduction. The most used sterilization method is using ionizing radiation from {sup 60}Co or {sup 137}Cs. For efficient application of SIT, an important item is the sterilizing dose. This must be as lower as possible in order to preserve insect behavior. In this work, it was studied the reproductive potential of fruit fly Ceratitis capitata, tsl VIENNA 8 strain, irradiated with different doses of gamma radiation. This strain has been used in population suppression programs at fruit-growing areas from Northeast of Brazil, through a partnership between CENA and Bio factory MOSCAMED Brazil, intending only sterile male releases. Radiation source used was a {sup 60}Co irradiator, with 17.2 x 1012 Bq. Individualized couples were distributed in a randomized delineament with 10 replicates for each treatment and eggs were collected for fifteen days. With 9 and 10 days old, pupae were irradiated with doses ranging from 30 to 120 Gy. All averages of emerged adult's percentages were higher than 90%. In regards to fecundity, different doses did not affect the number of eggs laid, being the overall mean around 30 eggs/couple/day. Fertility data showed that as radiation dose increases, sterility increases. It was concluded that the dose of 90 Gy can be used in Brazil, since to SIT programs a dose is chosen witch prevents an egg hatch higher than 1%. (author)

    Although the Brazilian Legislation does not clearly specify the requirements and the need to elaborate and apply the Environmental Risk Analysis, the Term of Reference to submit studies to Environmental Entities for E and P offshore activities has required the presentation of an {sup E}nvironment Risk Analysis{sup .} Nevertheless, the interactions or possible effects of these accidents as well as possible chronic discharges are not focused. The Environment Risk Analysis programs used world wide for offshore petroleum activities are very sophisticated and need intense research, specially by universities to be adequate and applicable in Brazil. The studies briefly described in this work, when developed may give the characteristics of Brazilian offshore, important information on the potential of the environment impact of the E and P activities, reducing significantly today's subjectivity on evaluation of impacts and environmental risks.

    Submarine groundwater discharge (SGD) and recycled seawater can provide chemical constituents to coastal zone, representing an important material flux pathway from land to sea in some areas. Geochemical tracers, like {sup 222} Rn and {sup 226} Ra, are advantageous for regional-scale assessment of SGD, because their signals represent values integrated through the water column that removes small-scale variations. These radionuclides are usually enriched in groundwater compared to seawater, can be measured at very low concentrations and are conservative. This work reports preliminary results of a study carried out in a series of small embayements of Ubatuba, Sao Paulo State-Brazil, covering latitudes between 23 deg 26{sup '}S and 23 deg 46{sup '}S and longitudes between 45 deg02{sup '}W and 45 deg 11{sup '}W. The main aims of this research were to set up an analytical method to assess {sup 222} Rn and {sup 226} Ra activities in seawater samples and to apply the excess {sup 222} Rn inventories obtained to estimate the submarine groundwater discharge. Measurements made during 2001/2002 included {sup 222} Rn and {sup 226} Ra in seawater, {sup 222} Rn in sediment, seawater and sediment physical properties. (author)

    Isotope Ratio Mass Spectrometry is the ideal method to determine with high precision the ratio of stable isotopes of light elements. Due to this fact, it is used in environmental research, especially in hydrological studies, avoiding the need of injection. This work implanted a method for analysis of water isotopes ({sup 18}O and {sup 2}H) and validated the method for the measurement of δ{sup 18}O, in the Laboratory of Isotope Ratio Mass Spectrometry of the Center for Development of Nuclear Technology. The performance of the method was evaluated according to the following criteria: stability, linearity, precision, accuracy and robustness. This method was applied to studies of groundwater in the watershed of the Engenho Nogueira Creek, located at the Federal University of Minas Gerais (UFMG) campus, in the northern region of the city of Belo Horizonte, Brazil. The watershed of the Engenho Nogueira Creek has been studied in several occasions in recent years for different purposes; however, the use of natural isotopes of water had never been applied to these studies. This technique can expand the diversity of data on the local aquifer, helping to fill gaps in its understanding, besides, it can confirm data previously obtained. The expansion of the academic and administrative units of the UFMG campus since 2000 implies in an incremented importance of the management of the local since the demand for water grows each year.

    2015-01-01

    Full Text Available This study aimed to show, based on the literature on the subject, the potential for dispersal and establishment of the chikungunya virus in Brazil. The chikungunya virus, a Togaviridae member of the genusAlphavirus, reached the Americas in 2013 and, the following year, more than a million cases were reported. In Brazil, indigenous transmission was registered in Amapa and Bahia States, even during the period of low rainfall, exposing the whole country to the risk of virus spreading. Brazil is historically infested by Ae. aegypti and Ae. albopictus, also dengue vectors. Chikungunya may spread, and it is important to take measures to prevent the virus from becoming endemic in the country. Adequate care for patients with chikungunya fever requires training general practitioners, rheumatologists, nurses, and experts in laboratory diagnosis. Up to November 2014, more than 1,000 cases of the virus were reported in Brazil. There is a need for experimental studies in animal models to understand the dynamics of infection and the pathogenesis as well as to identify pathophysiological mechanisms that may contribute to identifying effective drugs against the virus. Clinical trials are needed to identify the causal relationship between the virus and serious injuries observed in different organs and joints. In the absence of vaccines or effective drugs against the virus, currently the only way to prevent the disease is vector control, which will also reduce the number of cases of dengue fever.

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

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

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

    This article comprises geochemical, structural and radiometric investigations on radioactive pegmatites of the Borborema Pegmatitic Province in Northeast Brazil. The studied area is located in the surroundings of the city of Parelhas, in the geotectonic Province of Borborema. It is well known for its thousands of pegmatitic bodies exploited in primitive mines called garimpos. The main goal was to find an efficient, cheap and routine inspection procedure to identify the origin of commercialized radioactive columbite-tantalite (coltan) ore. The Brazilian Nuclear Energy Agency (CNEN) controls uranium commerce and nuclear activity in Brazil. Without an effective method to characterize coltan ores from different localities it is impossible to control the trade. The here presented new method was developed by correlating structural features of these pegmatites with the geochemical behavior of their coltan samples. It was found that the variation of U/Th vs. Nb 2 O 5 /Ta 2 O 5 provides geochemical signatures (analytical fingerprints) for the source location of such ore. The new method was tested with coltan samples of commercial batches from the Brazilian states of Amapa and Rondonia and also generated distinct geochemical signatures. A radiometric survey (CPS) to study the environmental impact of gamma radiation was also carried out in several mines and pegmatites. It included in situ measurements of pegmatite walls, enclosing rocks, soil, and accumulated water and revealed that gamma emitters are hardly solubilized and therefore environmental gamma radiation generally is not enhanced to a dangerous level.

    Brazil is a large producer of many minerals, with a favourable regulatory framework, tax policy and foreign investment legislation. Although there are strict environmental requirements, mining ventures can cope with them and they represent no obstacle to mining activities. Efficient regulatory agencies are in place, such as the Department of Mines (DNPM) and the Geological Survey (CPRM). The Brazilian mineral policy is set out in a number of different documents, the more important being the Federal Constitution and the Mining Code. Important constitutional amendments have been recently passed, so as to open Brazil`s economy to foreign investments.

    The Powerline Communications technology - PLC allows transmission of data, voice, image and access to high speed internet by the grid, so that a power plug can also be an access point to the network communication. Considering that the electric grid reaches the vast majority of households, there is great potential in using this technology as a tool to achieve the reality of digital inclusion in the country. However, its implementation must be accompanied by effective regulation, both through policies with respect to the conditions of use of radio frequencies, as in regulating the use of distribution networks of electricity as a means of transport for communication signal. In this context, the present article deals with the fundamental rules governing the application of PLC technology from the standpoint of the distributors and consumers of electricity, with attention to quality assurance of electrical energy and facility security.

The Brazilian Nuclear Energy Agency (CNEN) controls uranium commerce and nuclear activity in Brazil. Without an effective method to characterize coltan ores from different localities it is impossible to control the trade. The here presented new method was developed by correlating structural features of these pegmatites with the geochemical behavior of their coltan samples. It was found that the variation of the ratio U/Th versus Nb{sub 2}O{sub 5}/Ta{sub 2}O{sub 5} provides geochemical signatures (analytical fingerprints) for the source location of such ore. A test of the new method with coltan samples of commercial batches from the Brazilian states Amapa and Rondonia also generated distinct geochemical signatures. A radiometric survey (CPS) was carried out in several mines and pegmatites to study the environmental impact of gamma radiation. It included in situ measurements of pegmatite walls, host rocks, soil, and accumulated water and revealed that gamma emitters are hardly solubilized and environmental gamma radiation therefore generally is not enhanced to a dangerous level.

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

    In the same way that the majority of the countries, project financing of substructure in Brazil, in project finance modality, depend on a skillful structure of guaranties and contracts to become possible. In the case of projects of centrals of generation of electrical energy, that financial engineering becomes still more complicated. In Brazil, due to particularities of the sectors of electricity, the arrangements of guaranties requested but creditors pass to present levels of complexity and exigency well elevated. The contractual appliances that give support to the project finance, originally projected to developed countries, request an extreme adaptation to these particularities. The development of Brazil is directly related to its capacity in expanding the offer of electric energy in the just measure of the national necessity. In this context, the small central hydroelectric (PCH's) represent, actually, an efficient and fast form to complete the offer of energy in such a way to supply the crescent demand the national market. For its characteristics, that type of undertaking can be developed by small manager, from among which are the owners of the areas in which on can find these hydraulic potentials which, however they do not dispose of capital to integral raising. These undertakings are tasks, normally, of low global cost, at the rate of US$ 1.000,00/k W, and of a smaller ambient impact, compared to the return that they give to the enterprise and to the Brazilian electric system as a whole, by having to receive special attention in the planned politics to the sector and to merit a series of incentives to become business still more attractive. By thinking in the found difficulty by small enterprises in rising undertakings of generation of electric energy of small port through the convectional mechanisms of financing is being proposed in that work a well-founded methodology in the concepts of the modality of financing project finance.

    The search for new sources of renewable energy order to minimize environmental impacts has led the scientists to develop new alternatives, such as the use of recycling of frying oils to produce biodiesel. The reuse of these oils has the advantage of obtaining a biofuel with the cost / benefit competitive. However, the conditions of post-consumer oils require treatment prior to its conversion the chemical (transesterification), removing solid particulate contaminants and adjusting its color using the clay of Paraiba. The use of biodiesel as fuel presents a reduction of levels of environmental pollution. This study aimed to characterize clay of Paraiba to be used in the clearing of frying oil. It was observed through the results of the Xray fluorescence (XRF) and infrared spectroscopy by Fourier Transform (FTIR), which the clays tested, have been effective in clearing of frying oils, making them similar to oil 'virgin'.

    Brazilian energy sector has faced a series of transformations that have influence on national industry. The trial of economy globalization and the new energy sources Also available and output techniques created a more competitive business environment, where not only financial aspects are considered in industrial practices. In such environment, the industry seek for more efficient production techniques and greater importance given to environmental issues are responsible for making the decision processes associated to industrial activities more complex. In this context, the energy utilized by industry represents an important aspect of business course, justified by governmental concerns on attending all existing thermal energy demand. This paper aim is to support the decision process concerned to the choice of the best energy source to be applied in the industry. In order to reach such goal, a decision model was built based on multi criteria techniques applied to the case of textile industry in Ceara State. This sector is also one of the biggest natural gas consumers in Ceara, which has influenced on its choice in order to attend to a second goal of this paper: to focus the natural gas applications and support a greater insertion of this fuel in the market.

    The utilization of fuels of agricultural origin in the cycle diesel engines is a good alternative to reduce dependence on importation petroleum, since these fuels are a renewable source of energy. The utilization of biodiesel as biofuel is a contribution to the environment, reducing the qualitative and quantitative form levels of environmental pollution. The recycling of post-consumption oil helps reduce the uncontrolled disposal and environmentally dangerous, than to obtain fuel with a cost / benefit and offering a competitive alternative commercial advantage. However, these oils should go through a process of decontamination and clearing up the stage of chemical conversion which is used clay to lighten the oil. This work had as its objective to make a literature revision evaluating the potential of the clearing clay modified in Paraiba, used in post-consumption oils for application as biofuel. (author)

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

    The diabetes epidemic affects most countries across the world and is increasing at alarming rates in Latin America. Nearly 12 million individuals have diabetes in Brazil, and the current prevalence ranges from 6.3% to 13.5%, depending on the region and the diagnostic criteria adopted in each study. To provide an overview of diabetes care in Brazil, focusing on studies of diabetes epidemiology, prevalence of patients within the standard targets of care, and economic burden of diabetes and its complications. SciELO and PubMed searches were performed for the terms "diabetes," "Brazil," "Brazilian," and "health system"; relevant literature from 1990 to 2015 was selected. Additional articles identified from reference list searches were also included. All articles selected were published in Portuguese and/or English. Recent studies detected a prevalence of gestational diabetes mellitus of nearly 20%. Among patients with type 1 diabetes, almost 90% fail to reach target of glycemic control, with less than 30% receiving treatment for both hypertension and dyslipidemia. More than 75% of patients with type 2 diabetes are either overweight or obese. Most of these patients fail to reach glycemic targets (42.1%) and less than 30% reached the target for systolic and diastolic blood pressure, body mass index, or low-density lipoprotein cholesterol. Only 0.2% of patients reach all these anthropometric and metabolic targets. Brazil is the fourth country in the world in number of patients with diabetes. Regardless of the diabetes type, the majority of patients do not meet other metabolic control goals. The economic burden of diabetes and its complications in Brazil is extremely high, and more effective approaches for preventions and management are urgently needed. Copyright © 2015.

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

    Pinheiro, K.; Siqueira, F.

    2013-05-01

    Magnetic storms result from atypical processes generated in the Sun, the interaction between the solar wind and the Earth's magnetosphere and the energization of particles in the magnetosphere. As consequence, magnetic storms may cause problems on radio communication, in satellites, GPS imprecision and induce geomagnetic induced currents that my cause saturation and damage of transformers. Magnetic storms are measured in magnetic observatories, where it is possible to observe large variations in the horizontal magnetic field. These variations are most visible in equatorial or low-latitude magnetograms. In this work, we use low latitude dataset from three magnetic observatories in Brazil: Vassouras (Rio de Janeiro) that presents data since 1915, Tatuoca (Pará) since 1957 and data from a new magnetic observatory that was installed in Pantanal (Brazil) on the 22nd October 2012. Vassouras and Pantanal observatories are in the region of the South Atlantic Magnetic Anomaly. External magnetic field interactions in this region are poorly known due to the lack of magnetic data. Tatuoca observatory is located in another important geomagnetic region: the equatorial electrojet. In this work we present the data processing of the recent geomagnetic time series in Pantanal Observatory and its comparison with Vassouras and Tatuoca observatories in Brazil. We analyse the main characteristics of magnetic storms in these observatories, as the sudden commencement and their duration.

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

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

    Energy Technology Data Exchange (ETDEWEB)

    Armelin, Maria Jose Aguirre

    1978-07-01

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

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

    We report a 47 year-old man from the State of Mato Grosso do Sul, Brazil, with unifocal tibial paracoccidioidomycosis. A radiograph showed an osteolytic lesion on the tibial middle third diaphysis. The diagnosis was confirmed by histopathologic analysis, and treatment with sulfamethoxazole and trimethoprim was started. After three months, the patient showed significant clinical improvement. Ten months after treatment, the patient showed lesion bone healing. This case describes the rare occurrence of an osteolytic lesion caused by endemic Paracoccidioides brasiliensis in Latin America.

    The rate of generation of phosphogypsum is approximately 4.8 tons for each ton of phosphoric acid produced. The annual world production can be estimated at 150 million of tons. It is classified as NORM (Naturally Occurring Radioactive Material), in other words, it is a solid waste that contains radioactive elements of natural occurrence from the source rock. The large amount of phosphogypsum produced has been attracting attention of radiological protection institutions and environmental protection agencies in the world, given its high potential for contamination of the environment. In Brazil, this material has been used for several decades, especially for agricultural purposes. In this case, the phosphogypsum is used as a source of calcium and sulfur, as conditioner, and for correction of subsurface soil saturated with sodium, potassium and aluminum. Due to the presence of radionuclides in phosphogypsum, it is necessary to understand the mechanisms for transferring of natural radionuclides in the system soil/plant and to evaluate if the use of phosphogypsum in soil contributes to increased exposition of humans to the natural radioactivity. Experiments were accomplished in a greenhouse with lettuce cultivation in two types of soil (sandy and loamy) fertilized with four different amounts of of phosphogypsum. Samples of phosphogypsum, soil, lettuce and drainage water were analyzed being determined the radionuclides of interest ({sup 238}U, {sup 232}Th, {sup 226}Ra, {sup 228}Ra, {sup 2}'1'0Pb and {sup 210}Po). {sup 238}U and {sup 232}Th have been carried out by neutron activation analysis, Ra, Ra and Pb by gamma spectrometry and Po by alpha spectrometry techniques. Finally, Transfer Factor of soil-plant was calculated and the annual contribution to the effective dose committed due to the ingestion of lettuces of the experiment. Analyses of chemical, physical and mineralogical characterization of soil and phosphogypsum samples were also accomplished. The

    Brito, J.O.

    1997-01-01

    The annual consumption of fuelwood in Brazil is approximately equal to 180 million oil barrels, or 13.3% of all Brazilian primary energy use. Fuelwood consumption in the country is greater than the use of wood for industrial use. Fuelwood taken from existing forest has been a very common activity in Brazil. Forest plantations to support the Brazilian fuelwood consumption have not been important. As fuelwood consumption in the country is expected to increase in the future, it is important to increase the supply of wood by sustainable use of the existing natural forests. Even if they are far from the centers of consumption, these are only available reserves capable of supporting the Brazilian future fuelwood requirements. For this reason it is necessary to use advanced technology to convert the energy of wood efficiently into a form (such as electricity) to carry it to the centers of consumption. In addition, forest plantations would be established in the available areas, mainly for specific uses, as for charcoal production for the pig-iron and steel industries. In all the above plans, at least, the US3/2 billion/year that represents the current Brazilian fuelwood consumption should be returned to rehabilitate the forest growing stock. In addition, it would be used to stimulate the development and use of the most suitable systems of fuelwood conversion, improving the efficiency of energy production. (author)

    Roads provide the main means of transportation in Brazil. According to data from the Brazilian Department of Infrastructure and Transport, 96.2% of the passenger transportation and 61.8% of the cargo transportation are based on road infrastructure. However, three quarters of the Brazilian roads are in terrible, unsatisfactory or generally inadequate condition. Poor road conditions are responsible for a great number of accidents with severe consequences for the population and the environment. Given the importance of this matter, there is a need to develop an intelligent system for automatic classification of social and environmental sensitivity maps in order to support actions that respond to emergencies and to help in transportation planning, especially considering the heavy movement of hazardous cargoes such as petroleum and its derivates. For this, tools such as Geographic Information System (GIS) allow social-environmental and traffic engineering characterization maps to be analyzed on a unified, geo referenced digital base. This way, administrators can estimate which stretches of the network are more environmentally sensitive and which pose greater risks, and therefore draw inferences on the most socially and environmentally vulnerable. Social and environmental vulnerability data not only help in the classification of the areas which pose the greater risks, but also make it possible to decide on emergency support points, creating a culture of prevention in the area of hazardous cargo transportation. The case study on the state of Rio Grande do Norte provides a measure of the importance of such work. The city of Natal - the state capital - and the Guamare petrochemical facility are interconnected by 180 Km Road, on which more than 100 tanker trucks loaded with diesel and its derivates travel every day. This road is classified as in poor conditions and, according to the Brazilian Roads Police, it is one of the most dangerous. The relevance of this work is to show

    Full Text Available In 1970 the population of Brazil with 94,508,554 inhabitants was extreme youth, since 42.67% was composed of children under 14 years old. In that year the proportion of female was 50.2%. The population density increased from 1.17 inhabitants /km² in 1872 to 11.18 in 1970, and in this last year the range was 1.03 in the North region and 43.90 in the South-East region. The urban population increased from 31.24% in 1940 to 55.98% in 1970 and for the first time the rural population was smaller than the urban population. In 1950 concerning with marital status 39% of the population 15 years old and over was single and 54% married. In 1970 this rate was respectively 35.4% and 56.6%. The population economically inactive increased from 49.17% in 1940 to 52.24% in 1970. The literacy ratio increased from 43% in 1940, to 48% in 1950 and 68.04% in 1970. The crude birth rate was 43/1000 live births in 1950 and fell to 37.7/1000 in 1970. The fertility rate decreased from 179.3/1000 women (15-49 years old} to 156.7/1000 in 1960/70. The crude death rate decreased from 20.60/1000 inhabitants in 1940/50 to 9.4/1000 in 1960/70. The infant mortality rate still remains high: 171/1000 live births in 1940/50 and 170/1000 in 1971. Concerning with the size of the cities, 8 in 1940 had 100,000 or more inhabitants and in 1970 this number increased to 94 cities. The population growth increased from 2.38% in 1940/50, to 2.99% in 1950/60 and 2.83% in 1960./70. Brazil is the first country in population size in Latin America and the eighth in the world. Concerning his area, Brazil is the fifth country in size.

    Present conditions in Brazil are characterized by sharp contrasts and rapid social changes. Modern Brazilian civilisation has its roots in Indian, Portuguese and African cultures, which have grown together in the course of many years to form a harmonious union of civilisations. The Indian and Afro-Brazilian elements of this civilisation in particular have brought about a great number of syncretistic cults, hitherto scarcely explored; such as Candomblé, Umbanda, Macumba and Spiritualism, all of which, together with a vigorously active folklore, exert an important psychohygienic function. The institutions created within these cults provide a ritualized therapeutic treatment of psychiatric conditions supplementing the professional psychiatric care available to the population. The variety of forms of the Brazilian psychotherapy stretches from the pre-scientifical methods of the Indian medicine man through the seemingly medieval forms of exorcisme and spiritualism right to the scientifically founded psychotherapy in all its lines. Integrative endeavours towards a culture-anthropological psychotherapy are becoming evident.

    Full Text Available OBJECTIVE: This study provides the clinical pathological characteristics of 1301 cases of pediatric/adolescent lymphomas in patients from different geographic regions of Brazil. METHODS: A retrospective analyses of diagnosed pediatric lymphoma cases in a 10-year period was performed. We believe that it represents the largest series of pediatric lymphomas presented from Brazil. RESULTS: Non-Hodgkin lymphomas represented 68% of the cases, including those of precursor (36% and mature (64% cell origin. Mature cell lymphomas comprised 81% of the B-cell phenotype and 19% of the T-cell phenotype. Hodgkin lymphomas represented 32% of all cases, including 87% of the classical type and 13% of nodular lymphocyte predominant type. The geographic distribution showed 38.4% of the cases in the Southeast region, 28.7% in the Northeast, 16.1% in the South, 8.8% in the North, and 8% in the Central-west region. The distribution by age groups was 15-18 years old, 33%; 11-14 years old, 26%; 6-10 years old, 24%; and 6 years old or younger, 17%. Among mature B-cell lymphomas, most of the cases were Burkitt lymphomas (65%, followed by diffuse large B-cell lymphomas (24%. In the mature T-cell group, anaplastic large cell lymphoma, ALK-positive was the most prevalent (57%, followed by peripheral T-cell lymphoma, then not otherwise specified (25%. In the group of classic Hodgkin lymphomas, the main histological subtype was nodular sclerosis (76%. Nodular lymphocyte predominance occurred more frequently than in other series. CONCLUSION: Some of the results found in this study may reflect the heterogeneous socioeconomical status and environmental factors of the Brazilian population in different regions.

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

    Full Text Available At first sight, Brazil and France seem pretty distant from one another, but on the map, they are not separated by the Atlantic Ocean, but by the Oyapock River, located between the state of Amapa and French Guiana (French overseas department, creating a 730 km long international border. If the distance does exist, it is very different when we finely analyze some similarities in the field of biomedical research. France is the biggest country of Western Europe and covers 1/5 of the European Union. Apart from Metropolitan France, the country contains overseas territories, remnants of its colonial past. Over the centuries, France has known several political systems, from Ancient History to the current Republic. According to Ernest Renan, the French nation is more an ideology than a reality, primarily based on “the desire of living together and the wish to highlight our legacy”(1. The tragic attacks of November 2015 and all the reactions over the next days illustrate this. Brazil, discovered by the Portuguese explorer Pedro Alvares during the 16th century, is established on half of South America and is about 16 times bigger than France. This giant does not look to the past but is always moving forward. The concept of nation is really strong throughout the country, as shown by the enthusiasm of soccer players wearing the national auriverde jersey and the National Team supporters. Furthermore, they possess a strong culture of entrepreneurship defined by Stefan Zweig as the legacy of the early colonial era(2. Biomedical research is a human activity which aims to give expected solutions, and sometimes unexpected ones too, to a major and insoluble problem at a given time. This research is based on knowledge and will question it with a scientific approach, spread between what is known today and what will be known tomorrow.

    The largest alternative transportation fuels program in the world today is Brazil's Proalcool Program. About 6.0 million metric tons of oil equivalent (MTOE) of ethanol, derived mainly from sugar cane, were consumed as transportation fuels in 1991 (equivalent to 127,000 barrels of crude oil per day). Total primary energy consumed by the Brazilian economy in 1991 was 184.1 million MTOE, and approximately 4.3 million vehicles -- about one third of the total vehicle fleet or about 40 percent of the total car population -- run on hydrous or open-quotes neatclose quotes ethanol at the azeotropic composition (96 percent ethanol, 4 percent water, by volume). Additional transportation fuels available in the country are diesel and gasoline, the latter of which is defined by three grades. Gasoline A (regular, leaded gas)d has virtually been replaced by gasoline C, a blend of gasoline and up to 22 percent anhydrous ethanol by volume, and gasoline B (premium gasoline) has been discontinued as a result of neat ethanol market penetration

    This paper reports that security is defined in different ways by many international actors. To some, security is tied to the definition of an external threat to borders, as in the case of the NATO countries. To other, security is related to development, as in the case of most Third World countries. but notwithstanding different definitions, all countries recognize that the essence of security is the survival of the nation-state itself. The nuclear programs of Argentina and Brazil are among the oldest, most sophisticated and advanced nuclear programs anywhere in the Third World. The programs have never been explained on the basis of threat perception, and in this regard perhaps they constitute the most atypical form of nuclear proliferation known to date. Not surprisingly, any attempt to explain the rationale for the Brazilian and Argentine nuclear programs based on common issues of threat =merely confuses the issue. Thus, nationalism, the search for national identity and pride, the need to express self-sufficiency and the desire to keep options open in an insecure and evolving world order must all be analyzed to comprehend the likelihood of future types of nuclear proliferation. Meanwhile, the study of the contemporary era of Argentine-Brazilian nuclear rapprochement may provide new insights into the complex reasoning behind the decision of countries to go nuclear

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

    2017-04-01

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

    1994-01-01

    The development of a comprehensive program of sex education in Brazilian schools is described in the context of Brazil's culture and traditions such as the Carnival. The influence of Catholicism is explored as is the effect of the behavioral restrictions called for by scientists concerned about sexually transmitted diseases. The Brazilian response to homosexuality is described, and the emergence of a public discussion of sexuality in the media is traced. It is noted that improvements in the status of women have been held in check by a public ridicule of feminism and by the strength of the traditional patriarchal structures which dominate the culture. With this picture given of how the issue of sexuality fits into Brazilian life, the 1980s initiative on the part of the Work and Research Group for Sex Education is described. Opposition to this effort has largely taken the form of passive resistance; even the Catholic Church has not officially protested the sex education program. Details are provided about 1) the selection of teachers, teacher training, and weekly supervisory teacher meetings; 2) the way in which parental permission for student participation was gained; 3) the implementation of the program; 4) the successes achieved; and 5) the difficulties encountered. Finally, it is noted that plans were made to expand the sex education project from the Sao Paulo area to 6 additional large cities in 1994. Also planned is the publication of the Brazilian Guidelines for Comprehensive Sexuality which will explain the sex education methodology and be extremely valuable in the establishment of new projects.

    2015-10-01

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

Brazil put forward the initiative “Supporters of mediation”, that adds the concept of the United Nations “Responsibility to Protect” (R2P with the concept “Responsibility while protecting” (RwhileP. Brazil advocates for human rights. It marked Brazil's position on the rejection of humanitarian intervention, since the use of force leads to increased violence and instability, which manifested itself in the situation in the Middle East, and mass migration. For the country is characterized the analysis of the sources of conflict, adherence to international law, and understanding of the relationship between security and sustainable development, which is reflected in Brazil's foreign policy strategy, national security strategy.

  18. Status of uranium in Brazil

    International Nuclear Information System (INIS)

    Majdalani, S.A.; Tavares, A.M.

    2001-01-01

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

  19. Decentralization and REDD+ in Brazil

    Directory of Open Access Journals (Sweden)

    Fabiano Toni

    2011-01-01

    Full Text Available Recent discussions on REDD+ (Reducing Emissions from Deforestation and Forest Degradation, plus conservation, sustainable management of forests and enhancement of forest carbon stocks have raised optimism about reducing carbon emissions and deforestation in tropical countries. If approved under the United Nations Framework Convention on Climate Change (UNFCCC, REDD+ mechanisms may generate a substantial influx of financial resources to developing countries. Some authors argue that this money could reverse the ongoing process of decentralization of forest policies that has spread through a large number of developing countries in the past two decades. Central states will be accountable for REDD+ money, and may be compelled to control and keep a significant share of REDD+ funds. Supporters of decentralization argue that centralized implementation of REDD+ will be ineffective and inefficient. In this paper, I examine the relation between subnational governments and REDD+ in Brazil. Data show that some state governments in the Brazilian Amazon have played a key role in creating protected areas (PAs after 2003, which helped decrease deforestation rates. Governors have different stimuli for creating PAs. Some respond to the needs of their political constituency; others have expectations to boost the forest sector so as to increase fiscal revenues. Governors also have led the discussion on REDD+ in Brazil since 2008. Considering their interests and political power, REDD+ is unlikely to curb decentralization in Brazil.

    In practice of nuclear medicine, expert personnel routinely handle radiopharmaceuticals for diagnosis and radiotherapy. The control of intakes of radionuclides by workers can be performed through internal dosimetry techniques, as an integral part of the radiation protection program of the installation. The use of radiopharmaceuticals for diagnostic and therapeutic purposes in vivo and in vitro in Brazil is regulated by CNEN-NE Standards and 3:05 CNEN-NN 3.01. The International Atomic Energy Agency (IAEA) recommends the establishment of an internal monitoring program on workers, especially those subject to possible exposure to annual effective doses greater than 1 mSv. Note that, currently, in Brazil, are not available qualified laboratories to provide internal monitoring services in all regions in the country, if it were applied by CNEN, the requirement for internal monitoring of workers. This paper presents the development of a simple and low-cost methodology for in vivo monitoring of {sup 131}I in the thyroid. The proposed methodology is the use of portable monitor of surface contamination, equipment available and routinely used in all nuclear medicine services in Brazil. The monitor is calibrated with neck-thyroid simulator developed at the Laboratory of In Vivo Monitoring of IRD/CNEN-RJ. The equipment tested is suitable for application in in vivo occupational monitoring thyroid. This conclusion is based on the fact that the detection system has sufficient sensitivity for monitoring up to seven days after the incorporation of the radionuclide and guarantees {sup 131}I detection in values that result in effective doses below 1 mSv for the exposure scenarios adopted.

    An overview of small-scale hydro development in Brazil was presented in the context of the Brazilian energy sector. Brazil's energy sector is currently comprised of 45 per cent renewable energy. Brazil is the tenth largest energy producer in the world, with an installed capacity of 105.986 MW. Brazil currently has an estimated 258.410 MW of hydroelectric power potential. Small hydropower (SHP) plants in Brazil are defined as plants capable of producing up to 30 MW of power, with a reservoir area smaller than 12 km 2 . It is estimated that SHP plants will provide 5 per cent of Brazil's electrical supply by 2030. SHP plants in Brazil typically use Kaplan and Pelton hydraulic turbines, as well as Michell-Banki cross-flow turbines. Hydrokinetic turbine prototypes are also being designed at the Federal University of Brazil. Researchers are currently developing a diffuser enhancement design. However, there are currently no designs available that use peripheric generators. Researchers are currently investigating the design of fish-friendly turbines as well as mobile dams. Development projects in the Amazon region were outlined. tabs., figs.

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

    Malaria is still a major public health problem in Brazil, with approximately 306,000 registered cases in 2009, but it is estimated that in the early 1940s, around six million cases of malaria occurred each year. As a result of the fight against the disease, the number of malaria cases decreased over the years and the smallest numbers of cases to-date were recorded in the 1960s. From the mid-1960s onwards, Brazil underwent a rapid and disorganized settlement process in the Amazon and this migratory movement led to a progressive increase in the number of reported cases. Although the main mosquito vector (Anopheles darlingi) is present in about 80% of the country, currently the incidence of malaria in Brazil is almost exclusively (99,8% of the cases) restricted to the region of the Amazon Basin, where a number of combined factors favors disease transmission and impair the use of standard control procedures. Plasmodium vivax accounts for 83,7% of registered cases, while Plasmodium falciparum is responsible for 16,3% and Plasmodium malariae is seldom observed. Although vivax malaria is thought to cause little mortality, compared to falciparum malaria, it accounts for much of the morbidity and for huge burdens on the prosperity of endemic communities. However, in the last few years a pattern of unusual clinical complications with fatal cases associated with P. vivax have been reported in Brazil and this is a matter of concern for Brazilian malariologists. In addition, the emergence of P. vivax strains resistant to chloroquine in some reports needs to be further investigated. In contrast, asymptomatic infection by P. falciparum and P. vivax has been detected in epidemiological studies in the states of Rondonia and Amazonas, indicating probably a pattern of clinical immunity in both autochthonous and migrant populations.

    Brazil is a large country with a wide diversity of landscapes and geological features and has been an important world producer of mineral resources. Despite this, until the 90's of last century, there has not been much concern and policies about geological heritage and geoconservation. Only at the end of the century the National Geological Service (CPRM) included the physical characterization of areas with geotouristic interest in its mission of generation and diffusion of geological information. In 1997, was created the Brazilian Commission of Geological and Paleobiological Sites (SIGEP, http://sigep.cprm.gov.br), responsible for the assessment, description and publicizing the sites of geological heritage. This is by now the most comprehensive and relevant initiative to protect the national heritage. It is composed by a fully accessible national database composed by 167 certified sites presented as scientific papers. Furthermore, a web-based applicative for the inventory and protection of geological heritage sites is being developed by the National Geological Service. The wider knowledge about geological heritage can be a useful tool for its conservation and this has been an important goal in the creation of protected areas, by means of environmental education and tourism. In Brazil, actions, research and publications about the subject have increased in the last five years, as well as the outreach and responsible use of the geological heritage. Scientific meetings, conferences and courses are growing and spreading around the country. The main scientific meeting has been the Brazilian Symposium of Geological Heritage that in its second edition (2013) had more than 200 papers presented. At that meeting it was also created the Association in Defence of the Geomining Heritage and the Association of Aspiring Geoparks. Brazil has only one geopark in the Unesco's Global Geopark Network, that is the Araripe Geopark, created in 2006. By the moment, propositions are being

    1980-01-01

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

    The rising concerns about global warming and energy security have spurred a revival of interest in nuclear energy, giving birth to a 'nuclear power renaissance' in several countries in the world. Particularly in Brazil, in the recent years, the nuclear power renaissance can be seen in the actions that comprise its nuclear program, summarily the increase of the investments in nuclear research institutes and the government target to design and build the Brazilian Multipurpose research Reactor (BMR). In the last 50 years, Brazilian research reactors have been used for training, for producing radioisotopes to meet demands in industry and nuclear medicine, for miscellaneous irradiation services and for academic research. Moreover, the research reactors are used as laboratories to develop technologies in power reactors, which are evaluated today at around 450 worldwide.

    This study aims to describe the distribution of the hospital pharmacy workforce in Brazil. Data were acquired, during 2016, through the Brazilian National Database of Healthcare Facilities (CNES). The following variables were extracted: hospital name, registry number, telephone, e-mail, state, type of institution, subtype, management nature, ownership, presence of research/teaching activities, complexity level, number of hospital beds, presence of pharmacists, number of pharmacists, pharmacist specialization. All statistical analyses were performed by IBM SPSS v.19. The number of hospitals with a complete registry in the national database was 4790. The majority were general hospitals (77.9%), managed by municipalities (66.1%), under public administration (44.0%), had no research/teaching activities (90.5%), classified as medium complexity (71.6%), and had no pharmacist in their team (50.6%). Furthermore, almost 60.0% of hospitals did not comply with the minimum recommendations of having a pharmacist per 50 hospital beds. The Southeast region had the highest prevalence of pharmacists, with 64.4% of hospitals having a pharmaceutical professional. This may have occurred as this region had the highest population to hospital ratio. Non-profit hospitals were more likely to have pharmacists compared to those under public administration and private hospitals. This study mapped the hospital pharmacy workforce in Brazil, showing a higher prevalence of hospital pharmacists in the Southeast region, and in non-profit specialized hospitals.

    The rising concerns about global warming and energy security have spurred a revival of interest in nuclear energy, giving birth to a 'nuclear power renaissance' in several countries in the world. Particularly in Brazil, in the recent years, the nuclear power renaissance can be seen in the actions that comprise its nuclear program, summarily the increase of the investments in nuclear research institutes and the government target to design and build the Brazilian Multipurpose research Reactor (BMR). In the last 50 years, Brazilian research reactors have been used for training, for producing radioisotopes to meet demands in industry and nuclear medicine, for miscellaneous irradiation services and for academic research. Moreover, the research reactors are used as laboratories to develop technologies in power reactors, which are evaluated today at around 450 worldwide. In this application, those reactors become more viable in relation to power reactors by the lowest cost, by the operation at low temperatures and, furthermore, by lower demand for nuclear fuel. In Brazil, four research reactors were installed: the IEA-R1 and the MB-01 reactors, both at the Instituto de Pesquisas Energeticas Nucleares (IPEN, Sao Paulo); the Argonauta, at the Instituto de Engenharia Nuclear (IEN, Rio de Janeiro) and the IPR-R1 TRIGA reactor, at the Centro de Desenvolvimento da Tecnologia Nuclear (CDTN, Belo Horizonte).

    To identify the main counterfeit drugs seized by the Brazilian Federal Police and the states where seizures have been made. A retrospective descriptive study on expert reports produced by criminal investigators of the Federal Police between January 2007 and September 2010, in relation to counterfeit drugs, was carried out. The drugs with greatest numbers of seizures were selective phosphodiesterase-5 inhibitors that are used for treating male erectile dysfunction (Cialis® and Viagra®, mean = 66% ), followed by anabolic steroids (Durateston® and Hemogenin®: 8.9% and 5.7%, respectively). The greatest proportions of the counterfeit drugs were seized in the states of Paraná, Santa Catarina (both Southeastern Brazil) and São Paulo (Southeastern), and the number of non-authentic drugs sent for investigation increased by more than 200% over the study period. There were increases in seizures of smuggled drugs found together with counterfeit drugs: 67% of the seizures included at least one smuggled drug. Counterfeiting of drugs is a severe public health problem. Identification of the classes of counterfeit drugs present in Brazil and the main Brazilian states with this problem may facilitate future preventive and suppressive actions by the Brazilian bodies responsible for such actions.

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

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

    The Mourao hydroelectric power plant located in the city of Campo Mourao, in the state of Parana, southern region of Brazil, was inaugurated in 1964, with 7500 kW of installed power. Defects in the spillway surface of the dam had been identified throughout the time. With the purpose of recovering the concrete hydraulic surface, repair materials were proposed in this paper, considering technology development and environment conservation. Concrete mixtures containing recycled materials - low-density polyethylene (LDPE), polyethylene terephthalate (PET) and waste tires - had its performance tested in laboratory. Mechanical properties, such as compressive strength, tensile strength and adherence were evaluated using cylindrical concrete specimens. Results were appraised and the best compositions were selected to be tested on spillway surface of Mourao dam. (author)

    As from the flexibilization of the petroleum monopoly, which took place in the second half of the 1990's, the petroleum and gas sector in Brazil has undergone a series of changes that have directly impacted the commercial relations among the companies in the sector. The increases in operational efficiency and reduction of costs have become basic factors for the companies wishing to compete in this market. This paper presents a study whose objective is to map, model, and determine the costs involved in the process for internal movement in a warehouse used as logistics support to offshore petroleum production. Based on the description of the internal movement process for product storage, the main resources are identified. Then, a mathematical model based on Activity-Based Costing is draw up, in which the results generated comprise the values for internal movement costs for each type of product moved in the warehouse.

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

    The eggs are among the twenty foods consumed by the population of the five major regions of Brazil. Among the types of eggs, there are differences in nutritional value, which can vary according to the food of the bird. This study evaluating the elements Cl, K, Mg, Mn and Na considered essential micronutrients in food, because they are fundamental in several metabolic processes necessary for the maintenance and training of the human body. We analyzed three types of eggs: egg whites, of the quail, and the colonial in cooked and raw form, using the Instrumental Neutron Activation Analysis method (INAA). The egg samples were lyophilized and pulverized before analysis. To validate the methodology, reference materials NIST RM 8415 Whole Egg Powder and NIST SRM 1567 Wheat Flour were analyzed. The samples, reference materials and standards of the elements were irradiated for 20 seconds under a thermal neutron flux of 6,6x10{sup 12} cm -2 s -1 in the nuclear research reactor IEA-R1 of IPEN-CNEN / SP. The results were consistent with the values of the Brazilian Table of Food Composition (TACO)

    EMBRAPA (Empresa Brasileira de Pesquisa Agropecuaria) and Brasilia University developed a research project about the viability of carbonatite rock as agricultural fertilizer. As an initial experiment, several mixtures of carbonatite, limestone, phosphorous and potassium compounds were added as fertilizers in an oxisol area (red-latosol, according with Brazilian System of Soil Classification), in Distrito Federal, central Brazil. The experiment area was divided in 56 plots (4 x 7m) and each plot received a fertilizer mixture. The purpose of this work was to verify if the addition of fertilizer mixture to the soil modified its radiometric and resistivity properties and if it is possible to identify this change. Gamma-ray and electrical resistivity measurements were obtained in an experimental area and in a natural savannah type vegetation area. The results showed that the fertilizer addition modified soil natural properties causing a small increase in K, U, Th levels and decreasing ten times electrical resistivity. A low contrast of radiation was observed between plots, and then it was not possible to differentiate the several treatments in base of gamma-ray measurements. Electrical resistivity was efficient to identify three groups of plots related to mixtures characteristics, respectively with phosphorous, potassium and limestone / carbonatite predominance.

    Settlement and deforestation surrounding the Brazilian town of Rio Branco are seen here in the striking 'herring bone' deforestation patterns that cut through the rainforest. Rio Brancois the capital of the Brazilian state of Acre and is situated near the border with northeastern Bolivia. The town is a center for the distribution of goods, including rubber, metals, medicinal plants, Brazil nuts and timber. Colonization projects in the region are supported by farming, logging activities, and extensive cattle ranching. Much of the surrounding terrain is of a poorly-draining clay hardpan soil, and heavy rainfall periodically converts parts of the forested region to swamp.The large overview image was acquired by the Multi-angle Imaging SpectroRadiometer's vertical-viewing (nadir) camera on July 28, 2000, and covers an area of 336 kilometers x 333 kilometers. A plume of smoke is visible north of the Rio Branco road, which roughly parallels the slender, twisting Rio Abuna. Most of the major rivers in the image provide reference points for state or international (Bolivia-Brazil) boundaries, and flow northeast to the Rio Madeira (east of the smoke plume). The border between Acre and the Bolivian department of Pando is marked by the Rio Abuna. Pando's southern boundary with the department of Beni is marked by the Rio Madre de Dios, the large river in the lower half of the image.The two higher-resolution inset images highlight a settled area north of the town of Rio Branco. These nadir views cover an area of 60 kilometers x 67 kilometers, and were acquired eleven months apart during Terra orbits 3251 and 8144. In the later image, more haze is present, possibly due to smoke from fires on that day. Comparing the two images provides a method of measuring the changes and expansion in the area of cleared land. One newly cleared patch is apparent near the middle of the later image, slightly off to the right. This polygon represents an area of about 16 square kilometers, or 4000

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

    To analyze the spatial distribution of homicide mortality rates among males 15 to 49 years old in the state of Pernambuco, Brazil, for the periods of 1980 to 1984 and 1995 to 1998, and to identify violence clusters. Mortality data were obtained from the Brazilian Ministry of Health's Mortality Information System. The mean homicide mortality rate was estimated for each municipality in the state for the two periods. The Moran coefficient was calculated to determine spatial autocorrelation. (The Moran coefficient ranges from -1 to +1, with a positive coefficient indicating a cluster of similar values, and a negative coefficient indicating adjacent dissimilar values.) To identify clusters of municipalities with either high or low homicide mortality rates, the local indicator of spatial association (LISA) was used. Finally, a Moran map was constructed to identify municipalities with statistically significant LISA values and to identify clusters of municipalities with either high or low homicide mortality rates. The Moran coefficient for 1980-1984 was 0.392, and for 1995-1998 it was 0.291 (P Maconha). This study suggests that the violence clusters are not the result of the socioeconomic conditions per se, but rather the consequence of the interaction between poor economic conditions and drug trafficking.

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

    2010-01-01

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

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

    Full Text Available This article analyzes the differences in inter-generational social mobility and schooling between white, brown, and black men in Brazil. The main objective is to analyze inequality of opportunities for mobility and educational transitions. The results indicate that for individuals from lower social origins, inequality of opportunities is significantly marked by racial differences, and that for persons originating in the upper classes, racial inequality influences the odds of social mobility. The results suggest that theories of stratification by race and class in Brazil should be rethought, taking into account the observed interactions between race and class.

    The construction of hydropower plants unquestionably impacts the environment and communities. But countries such as Brazil have been able to build up a sophisticated socio-environmental legislation and institutions as well as a democratic and participative licensing process to protect the nature and the population affected. In some cases, plants greatly contribute towards the creation of local welfare to the population as well as good environmental practices. As a good example of best practices on socio-environmental standards, we will analyze Jirau Hydropower Project, currently under construction on the Madeira River, north of Brazil.

    To design, modify, and expand surface facilities is a multidisciplinary task which involves substantial financial resources. It can take months or years to complete, depending on the size and level of detail of the project. Nowadays, the use of Next Generation Reservoir Simulators (NGRS) is the most sophisticated and reliable way of obtaining field performance evaluation since they can couple surface and subsurface equations, thus eliminating the need of lengthy multiphase flow tables. Furthermore, coupling a NGRS with an optimizer is the best way to accomplish a large number of simulation runs on the search for optimized solutions when facilities are being modified and/or expanded. The suggested workflow is applied to a synthetic field which reproduces typical Brazilian offshore deep water scenarios. Hundreds of coupled simulation runs were performed and the results show that it is possible to find optimal diameters for the production lines as well as the ideal location for the production / injection platform.

    The Salobo 3A polymetallic Cu (Au-Mo-Ag) deposit, located in the northern part of the Carajas Mineral Province, Para, consists of a metavolcano-sedimentary sequence represented by iron formation, amphibolite, schist and quartzite of the Igarape Salobo Group. This rock sequence rest uncomformably on the gneissic basement of the Xingu Complex. The copper mineralization hosted by iron formation consists of bornite-chalcocite and bornite-chalcopyrite disseminations associated with magnetite. The geochronological data determined through the application of the Rb-Sr, Sm-Nd and Pb-Pb methods, contribute to characterize the complex evolution of both the geological setting and the cupriferous mineralization of the Salobo deposit. The 3.11-2.92 Ga interval (T{sub DM}, Sm-Nd, whole rock) represents the age of the igneous protholith of the gneiss. The {epsilon}{sub Nd} values calculated for the time of the gneiss formation (2859 Ma) vary between +1.02 and -1.08, and indicate a short period between the mantle-crust differentiation epoch and the gneiss formation. Moreover, the {epsilon}{sub Nd} parameter suggest a mantle source with late crustal contamination. The application of the leaching technique allows a gradual extraction of Pb at each leaching step and it was applied to chalcocite and magnetite. The 2762 {+-} 180 Ma and 2776 {+-} 240 Ma ages determined on those minerals are interpreted to be close to the epoch of the formation of the copper mineralization with Uu and Th enrichment and of the iron formation deposition, respectively, in a conventional setting. The leaching technique was also applied to tourmaline from gneiss and quartzite, and the age near to 2400 Ma was attributed to its formation. The random variability of the Pb isotope compositions of the tourmaline together with its petrographic characteristics suggest the boron source is not associated with the metassedimentary rocks of the Igarape Salobo Group. The Sm-Nd mineral isochron attributed to schists yielded an age of 2426 {+-} 13 Ma, ({sup 143} Nd/{sup 144} Nd){sub 0} equal to 0.50936 and MSWD of 1.125, for the formation of the minerals biotite-grunerite-garnet. Transamazonic ages obtained in magnetite from brecciated iron formation (2172{+-} 230 Ma, Pb-Pb) and chloritized gneisses (2135 3{+-}Ma, Rb-Sr, whole rock), are interpreted as related to greenschist facies metamorphic processes. As copper sulfides, gold, molybdenite fill fractured rocks affected by shearing and low grade metamorphism, it is possible that minerals were remobilized, at least in part, during the Transamazonian. The {sup 87} Sr/{sup 86} Sr initial ratio of 0.728 for the Rb-Sr reference isochron shows that such a event affected rocks with sifnificant crustal residence. The high and random {sup 87} Sr/{sup 86} Sr ratios found for tourmaline and carbonate reflect the influence of rocks with significant crustal residence. In conclusion, the analyses of the isotopic data are in accordance with a syngenetic origin for the Salobo copper primary mineralization, and had a polycyclic evolution associated with the Carajas-Cinzento strike-slip system at the northern portion of the Carajas Mineral Province.

    Since the radiological accident in Goiania in 1987, the IRD (Institute of Radiological Protection and Dosimetry - IRD / CNEN) has been developing tools to support decision-making processes after a nuclear or radiological accident which leads to an environmental contamination and to an exposure of individuals the public These processes include the establishment of a supporting multicriteria model, which involves the application of protective and remediation measures of contaminated areas in tropical environments. In this study, it was performed an evaluation of the efficiency of these measures in order to determine the consequences of their implementation, based on results obtained from the code SIEM (Emergency Integrated System), which constitutes an environmental mode1 developed at IRD to simulate this type of accident. In order to perform this evaluation, it was first developed a database containing descriptions of various protection/remediation measures, which could be applied nationwide. Afterwards, some basic scenarios were established, considering the environmental, housing and food characteristics of the population of the vicinity of the nuclear power plants in Angra dos Reis (state of Rio de Janeiro). Thus, the accident simulations were carried out separately containing releases of {sup 137}Cs, {sup 90}Sr and 131 I. The results showed that the dose reduction varies according to the extent and the timing of the remediation measure applied. Although it is possible to establish some basic guidelines, generic solutions are not recommended, since the resulting doses are highly dependent on the actual situation. Any decision-making process should be made case by case, according to the actual conditions of the affected area and to the occupation characteristics and use of the affected areas, considering the characteristics of the source term of contamination, the time of the year in which the accident occurs, the local agricultural practices and food habits of real people affected. For both types of area, it was observed that it would be appropriate to assign the security measures according to three criteria: (i) its efficiency in reducing the doses in the first year, (ii) its efficiency in reducing the dose of long-term and (iii) the effect of delay in implementing the measure efficiency in reducing doses. Finally, the results of this work will be complemented in the database in order to provide support for multi-criteria analysis in decisionmaking process after this type of accident. (author)

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

    The price paid to ethanol producers in Brazil as part of that country's oil substitution programme are examined over time. In the 1980s the price dropped dramatically to around 45% of that paid in 1978. In the 1990s prices have continued to fall but not so rapidly (about 12% over 5 years). Further falls will depend on technological progress. (UK)

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

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

    In Brazil and worldwide the nuclear power has occupied a prominent position with many applications in industry, power generation, environment and medicine, improving the quality of tests and treatments, therefore people's lives. Uranium is the main element used in nuclear facilities and it s employed as base material to generation of electricity in the manufacture of radiopharmaceuticals. In the '50s, during the Cold War, the then newly created International Atomic Energy Agency proposed to oversee nuclear facilities and encourage the manufacture of nuclear fuels with low-enriched uranium (LEU) fuel came then type Material Test Reactor (MTR), manufactured initially in U{sub 3}O{sub 8} and U{sub 3}Si{sub 2} later, both dispersed in aluminum. The use of this technology requires a constant improvement of all processes involving the manufacture of MTR subject to several international protocols, which seek to ensure the reliability of the fuel from the standpoint of practical and environmental. In this context, the control of impurities, from the point of view of neutron economy, directly affects the quality of any nuclear fuel, so strict control is necessary. The literature has reported procedures which, beyond generating residues, are lengthy and costly, they need calibration curve and consequently reference materials. The aim of this work is to establish and validate a methodology for nondestructive quantitative chemical analysis, low cost and analysis time, as well as minimize the generation of waste, for multielement determination of major constituents (Utotal and Si) and impurities (B, Mg, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Cd and others) present in U3O8 and U{sub 3}Si{sub 2}, meeting the needs of nuclear reactors in the nuclear fuel qualification type MTR. For that purposes, will be applied the X-ray fluorescence technique which allows fast chemical and nondestructive analysis, aside from sample preparation procedures that do not require previous

  3. Biochar: An emerging policy arrangement in Brazil?

    International Nuclear Information System (INIS)

    Rittl, Tatiana Francischinelli; Arts, Bas; Kuyper, Thomas W.

    2015-01-01

    Highlights: • The Brazilian biochar debate is driven by Embrapa experts. • The dominant ADE/biochar discourse has been replaced by biochar/technology discourse. • The international biochar/climate change discourse hardly resonates in Brazil. • Biochar topic is not covered by any formal procedure in Brazil so far. - Abstract: Biochar, the solid product of pyrolysis, has emerged as a new technology and policy tool to address various environmental challenges (climate change, food production and agricultural waste management). The concept of biochar drew its inspiration from Amazonian practices that had led to the creation of Amazonian Dark Earth (ADE): fertile soils rich in (bio)char and human artefacts. In this article, we conceptualize biochar as an emerging policy arrangement, and examine it along the four dimensions of the Policy Arrangement Approach (PAA), which are actors, discourse, power and rules. We focus on Brazil as an important player in the international biochar debate. Our analysis shows that science experts are the predominant players in the network, while policy-makers, businessmen and farmers are marginally positioned. Experts from Embrapa occupy central positions and thus exercise most power in the network. Moreover, experts linked to ADE have lost prominence in the network. The reason for this is to be found in the shift from the ADE/biochar to the biochar/technology discourse. The latter discourse includes different coalitions such as ‘climate change mitigation’, the ‘improvement of soil fertility’ and ‘improving crop residue management’. Although the biochar/climate coalition is dominant at the international level, it is far less prominent in Brazil. Nationally, it is particularly the discourses of ‘improvement of soil fertility’ and ‘improving crop residue management’ which have prompted actors’ relationships and practices. However, the biochar/technology discourse has not (yet) been formally institutionalized in

    Full Text Available Fish consumption per capita in Brazil is relatively modest when compared to other animal proteins. This study analyses the influence of protein prices, other food prices and population income on the fish demand in Brazil. First, the problem of fish supply in Brazil is characterized. It is followed by reviews of the relevant economic theory and methods of Almost Ideal Demand System - AIDS and their elasticity calculations. A descriptive analysis of fish demand in Brazil using the microdata called "Pesquisa de Orçamento Familiar" (Familiar Budget Research - POF 2002-2003 is presented. Finally, demand functions and their elasticities are calculated for two different cases: one considering five groups of animal proteins (Chicken; Milk and Eggs; Fish; Processed Proteins and Red Meat and other with seven groups of food categories (Cereals; Vegetables and Fruits; Milky and Eggs; Oils and Condiments; Fish; Other processed foods; and Meats. The main results are: per capita consumption of fish (4.6 kg per inhabitant per year is low in Brazil because few households consume fish. When only households with fish consumption are considered, the per capita consumption would be higher: 27.2 kg per inhabitant per year. The fish consumption in the North-East Region is concentrated in the low-income class. In the Center-South Region, the fish consumption is lower and concentrated in the intermediate income classes. The main substitutes for fish are the processed proteins and not the traditional types of meat, such as chicken and red meat.

    Full Text Available AbstractIntroduction:Congenital heart disease is an abnormality in the structure or cardiocirculatory function, occurring from birth, even if diagnosed later. It can result in intrauterine death in childhood or in adulthood. Accounted for 6% of infant deaths in Brazil in 2007.Objective:To estimate underreporting in the prevalence of congenital heart disease in Brazil and its subtypes.Methods:The calculations of prevalence were performed by applying coefficients, giving them function rates for calculations of health problems. The study makes an approach between the literature and the governmental registries. It was adopted an estimate of 9: 1000 births and prevalence rates for subtypes applied to births of 2010. Estimates of births with congenital heart disease were compared with the reports to the Ministry of Health and were studied by descriptive methods with the use of rates and coefficients represented in tables.Results:The incidence in Brazil is 25,757 new cases/year, distributed in: North 2,758; Northeast 7,570; Southeast 10,112; South 3,329; and Midwest 1,987. In 2010, were reported to System of Live Birth Information of Ministry of Health 1,377 cases of babies with congenital heart disease, representing 5.3% of the estimated for Brazil. In the same period, the most common subtypes were: ventricular septal defect (7,498; atrial septal defect (4,693; persistent ductus arteriosus (2,490; pulmonary stenosis (1,431; tetralogy of Fallot (973; coarctation of the aorta (973; transposition of the great arteries (887; and aortic stenosis 630. The prevalence of congenital heart disease, for the year of 2009, was 675,495 children and adolescents and 552,092 adults.Conclusion:In Brazil, there is underreporting in the prevalence of congenital heart disease, signaling the need for adjustments in the methodology of registration.

  6. Brazil to Join the European Southern Observatory

    Science.gov (United States)

    2010-12-01

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

  7. Ehrlichiosis in Brazil Erliquiose no Brasil

    Rafael Felipe da Costa Vieira

    2011-03-01

    Full Text Available Ehrlichiosis is a disease caused by rickettsial organisms belonging to the genus Ehrlichia. In Brazil, molecular and serological studies have evaluated the occurrence of Ehrlichia species in dogs, cats, wild animals and humans. Ehrlichia canis is the main species found in dogs in Brazil, although E. ewingii infection has been recently suspected in five dogs. Ehrlichia chaffeensis DNA has been detected and characterized in mash deer, whereas E. muris and E. ruminantium have not yet been identified in Brazil. Canine monocytic ehrlichiosis caused by E. canis appears to be highly endemic in several regions of Brazil, however prevalence data are not available for several regions. Ehrlichia canis DNA also has been detected and molecularly characterized in three domestic cats, and antibodies against E. canis were detected in free-ranging Neotropical felids. There is serological evidence suggesting the occurrence of human ehrlichiosis in Brazil but its etiologic agent has not yet been established. Improved molecular diagnostic resources for laboratory testing will allow better identification and characterization of ehrlichial organisms associated with human ehrlichiosis in Brazil.Erliquiose é uma doença causada por rickettsias pertencentes ao gênero Ehrlichia. No Brasil, estudos sorológicos e moleculares têm avaliado a ocorrência de espécies de Ehrlichia em cães, gatos, animais selvagens e seres humanos.

    1998-01-01

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

  9. Argentina and Brazil: an evolving nuclear relationship

    International Nuclear Information System (INIS)

    Redick, J.R.

    1990-01-01

    Argentina and Brazil have Latin America's most advanced nuclear research and power programs. Both nations reject the Non-Proliferation Treaty (NPT), and have not formally embraced the Tlatelolco Treaty creating a regional nuclear-weapon-free zone. Disturbing ambiguities persist regarding certain indigenous nuclear facilities and growing nuclear submarine and missile capabilities. For these, and other reasons, the two nations are widely considered potential nuclear weapon states. However both nations have been active supporters of the International Atomic Energy Agency (IAEA) and have, in recent years, assumed a generally responsible position in regard to their own nuclear export activities (requiring IAEA safeguards). Most important, however, has been the advent of bilateral nuclear cooperation. This paper considers the evolving nuclear relationship in the context of recent and dramatic political change in Argentina and Brazil. It discusses current political and nuclear developments and the prospects for maintaining and expanding present bilateral cooperation into an effective non-proliferation arrangement. (author)

  10. Teenage pregnancy and moral panic in Brazil.

    Science.gov (United States)

    Heilborn, Maria Luiza; Brandão, Elaine Reis; Da Silva Cabral, Cristiane

    2007-01-01

    This paper examines teenage pregnancy as a social-historical construction of increasing concern in Brazil. It presents findings from over five years of empirical research alongside an analysis of a sample of newspaper articles representative of the dominant positions in the Brazilian press concerning teenage pregnancy. In contrast to mainstream arguments and to broader moral panic surrounding teenage pregnancy, we argue that contemporary patterns of sexual behaviour among young people in Brazil do not signal growing permissiveness and are not straightforwardly related to poverty, family dysfunction or lack of life projects on the part of young people themselves. On the contrary, early pregnancy and parenthood retain strong continuities with core Brazilian values and norms of sexual culture.

  11. [Toxicity and apple production in southern Brazil].

    Science.gov (United States)

    Klanovicz, Jó

    2010-03-01

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

  12. Coccidia of gallinaceous meat birds in Brazil

    Directory of Open Access Journals (Sweden)

    Marcel Teixeira

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

    2008-08-01

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

    Full Text Available Norovirus (NoV infections are a major cause of acute gastroenteritis outbreaks around the world. In Brazil, the surveillance system for acute diarrhoea does not include the diagnosis of NoV, precluding the ability to assess its impact on public health. The present study assessed the circulation of NoV genotypes in different Brazilian states by partial nucleotide sequencing analysis of the genomic region coding for the major capsid viral protein. NoV genogroup II genotype 4 (GII.4 was the prevalent (78% followed by GII.6, GII.7, GII.12, GII.16 and GII.17, demonstrating the great diversity of NoV genotypes circulating in Brazil. Thus, this paper highlights the importance of a virological surveillance system to detect and characterize emerging strains of NoV and their spreading potential.

  1. Perspectives on invasive amphibians in Brazil.

    Directory of Open Access Journals (Sweden)

    Lucas Rodriguez Forti

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

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

  8. Biological Control in Brazil: an overview

    Directory of Open Access Journals (Sweden)

    José Roberto Postali Parra

    2014-10-01

    Full Text Available The use of Biological Control methods is on the increase, mainly as a result of the mobilization of human resources in entomology studies since the establishment of graduate programs in this country in the 1960s. This review approaches the retrospective of Biological Control in Brazil in recent decades, with an emphasis on the "culture of applying agrochemicals" adopted by Brazilian growers, which constrains progress in this area. Successful cases of Biological Control have been reported on in Brazil and there are, in fact, excellent programs in place that use insects or entomopathogenic microrganisms for insect pest control. Most of the studies in this area have been published in Portuguese and are, therefore, not readily available internationally. Importantly, half of the planted sugarcane (Saccharum officinarum, around four million hectares, is treated with natural enemies (insects and/or pathogens. In contrast to other countries that employ Biological Control in small areas, the challenge in Brazil is to implement programs in large farms. Many obstacles must be overcome and discussed in working groups so that we can assume a world leadership position in the use of Biological Control in tropical regions as Brazil is already considered the leader in tropical agriculture. In this review, use of Biological Control is discussed within the Integrated Pest Management philosophy, as a path toward sustainable agriculture that is in harmony with other pest control methods. We must develop a technology of Biological Control adapted to tropical regions, rather than copying models developed for temperate regions, which are usually inappropriate for Brazilian conditions.

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

  20. Biomechanical comments about Triassic dinosaurs from Brazil

    Rafael Delcourt

    2012-01-01

    Full Text Available Triassic dinosaurs of Brazil are found in Santa Maria and Caturrita formations, Rio Grande do Sul state, Brazil. There are three species known from the Santa Maria Formation (Staurikosaurus pricei, Saturnalia tupiniquim and Pampadromaeus barberenai, and two from Caturrita Formation (Guaibasaurus candelariensis and Unaysaurus tolentinoi. These dinosaur materials are, for the most part, well preserved and allow for descriptions of musculature and biomechanical studies. The lateral rotation of the Saturnalia femur is corroborated through calculations of muscle moment arms. The enhanced supracetabular crest of Saturnalia, Guaibasaurus, Staurikosaurus, Herrerasaurus ischigualastensis, Efraasia minor and Chormogisaurus novasi suggests that basal dinosaurs may have maintained an inclination of the trunk at least 20º on the horizontal axis. The pectoral girdle articulation of basal sauropodomorphs (Saturnalia and Unaysaurus was established using a new method, the Clavicular Ring, and the scapular blade remains near 60º on the horizontal axis. This is a plesiomorphic condition among sauropodomorphs and is also seen in the articulated plateosauridae Seitaad ruessi. The Brazilian basal dinosaurs were lightweight with a body mass estimated around 18.5 kg for Staurikosaurus, 6.5 kg for Saturnalia, and 17 kg for Guaibasaurus. Pampadromaeus probably weighed 2.5 kg, but measures of its femur are necessary to confirm this hypothesis. The Triassic dinosaurs from Brazil were diversified but shared some functional aspects that were important in an evolutionary context.

    2016-08-01

    Outpatient plastic surgery is growing around the world. This industry faces unique challenges in terms of patient selection and standards of practice to ensure safety and cost-effectiveness. This review will highlight information about anesthesia practice for outpatient cosmetic surgery in Brazil, especially regarding regulation, legislation, and medical tourism. Medical tourism is growing worldwide, with a flow of patients traveling from developed to developing countries where procedures can be done at a fraction of the cost as in the patient's home country. Though generally well tolerated, there are concerns about incomplete data on outcomes of office-based surgeries and lack of safety standards. Brazil is one of the world's leaders in cosmetic surgery. Strong legislation governing outpatient facilities and continued development of accrediting standards for healthcare facilities are indications of a commitment to patient safety and high quality of care. Although the market for medical tourism in this country is high, there are still barriers to overcome before Brazil reaches its full potential in this industry.

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

  3. Bioethics and Christian theology in Brazil.

    Dos Anjos, Márcio Fabri; Lepargneur, Hubert François

    2008-01-01

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

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

    Arduini, Giovanna Abadia Oliveira; Rodrigues, Letícia Pinto; Trovó de Marqui, Alessandra Bernadete

    This work aimed to characterize mortality by sickle cell disease in Brazil. The MEDLINE electronic database was searched using the terms 'mortality' and 'sickle cell disease' and 'Brazil' for articles published in the last five years aiming to provide a current analysis of the subject in question. Eight studies on mortality by sickle cell disease were carried out in the Brazilian states of Maranhão, Bahia, Minas Gerais, Rio de Janeiro and Mato Grosso do Sul. The majority of the deaths occurred in patients with sickle cell anemia, which is the most common genotype and causes the most severe clinical manifestation of the disease. In summary, there are few published studies on mortality related to sickle cell disease in Brazil, and most are from the state of Minas Gerais. This study emphasizes the importance of developing more studies on sickle cell disease mortality, so that it may be possible to profile gene carriers and give health professionals more data to strategize the delivery of more effective assistance to these individuals. Despite the early diagnosis of sickle cell disease by the Neonatal Screening Program and the use of preventive and therapeutic measures (penicillin, immunization and hydroxyurea), mortality by sickle cell disease on the world stage is still significant.

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

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

  9. The Devonian trilobites of Brazil: A summary

    2015-12-01

    Devonian trilobites are found in three major Paleozoic intracratonic basins of Brazil (Amazonas, Parnaíba, and Paraná). The trilobites represent the families Homalonotidae, Dalmanitidae, and Calmoniidae. The distribution of these taxa in the Brazilian territory is summarized here because of their remarkable scientific and historical importance, and a revised taxonomy and lithostratigraphy of the Devonian (Pragian - Famennian) trilobites from Brazil is presented, based on new research and recent literature. Homalonotids and dalmanitids are relatively cosmopolitan, whereas calmoniids are more endemic and seem to have been restricted to marine cold-waters of the southern hemisphere (Malvinokaffric Realm). Although the trilobites within the Brazilian intracratonic basins are approximately contemporaneous, they show various patterns of endemism and biogeographical affinities with other Malvinokaffric areas such as Bolivia, South Africa, and the Falkland (Malvinas) Islands. At family level, therefore, trilobite diversity from Brazil is comparatively low, which may indicate biogeographical filtering related to the distance and/or remoteness of the Brazilian basins from more open oceanic waters.

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

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

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

  13. Access to Environmental Justice in Brazil

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

    This paper presents the Environmental and Safety Educational Campaign on the care in the small mining 'garimpo' with radioactive ore of uranium and thorium. These radionuclides are the major source of radioactive material present in certain mineral from rocks for example, tantalite / columbite, granites with cassiterite coal, phosphates, zirconate and rare-earth elements. The occurrence of radioactive ores in some sites has risen especial attention from CNEN such as in Borborema Mountain, where Uranium and Thorium are found scattered in pegmatite bodies from Serido region between Rio Grande do Norte and Paraiba states, and in Amapa state, in the Amazonian forest region, where thorianite was being illegally mined. Besides work accident risks inherent to this activity, there are radiological risks, showing the need to adapt measures and actions aiming at the health and safety of the small miners and population in general. The campaign involves cooperatives, trade unions, schools, non-governmental organization, entities involved in national security and others take part. The objective is to foment actions of radiological safety, in order to guarantee the protection and safety of the workers, their families and population. (author)

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

  13. Fishers' knowledge and seahorse conservation in Brazil

    Directory of Open Access Journals (Sweden)

    Oliveira Tacyana PR

    2005-12-01

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

  14. Journalism as a profession in Brazil

    2011-12-01

    Full Text Available Journalism as a profession in Brazil discusses the professional characteristics of Journalism in Brazil under the following aspects: 1 formal conditions of access, 2 conditions and effects of the monopoly on the journalistic activity 3 presence of a distinct culture and ethic, based on the notion of the journalist’s social responsibility and 4 characteristics of the real community of individuals who share the journalistic identity. Based on this scope, we can perceive the singularity of the Brazilian formal access conditions, albeit currently in transition. The university diploma for professional journalists, a recently eliminated mandatory requirement, created in the past a specific access condition and produced a field of specialized journalists with a university diploma. The journalists debate today about the end of their access card and a total lack of professional regulation. At the same time, there is a reduction of formal job positions, which are more concentrated with the large media groups, and worsening of working conditions and salaries. The emergence of other types of functions, due to new technological characteristics of the communication field, although potentially increasing professional possibilities, generate dilemmas regarding production and distribution of information. To these new challenges old ones have to be added, such as the need to ethically equate the work done by press offices, as these consist today the majority of job positions for journalists in the country. This work expands the discussion about these characteristics of the journalistic profession in Brazil based on quantitative and qualitative dada produced by the Comprehensive Analysis of Brazilian Communications and Telecommunications.

    Brazil is a large country, with an evolving economy, but marked social inequalities. The population is formed by an admixture of native Brazilians, Europeans, and Africans; is predominantly urban; and faces rapid aging. Time trends related to health behaviors show a substantial reduction in smoking rates, but a rising prevalence of overweight and obesity, unhealthy eating habits, and insufficient physical activity. The high prevalence of hypertension and the increasing prevalence of diabetes mellitus are also causes for concern. Cardiovascular disease (CVD) has been the leading cause of mortality since the 1960s and has accounted for a substantial percentage of all hospitalizations. In 2011, CVD was responsible for 31% of all deaths, with ischemic heart disease (31%) and cerebrovascular diseases (30%) being the leading CVD causes. Despite an increase in the overall number of CVD deaths, the age-adjusted mortality rates for CVD declined 24% between 2000 and 2011. Health care delivered by Brazil's universal public health system, which focuses on primary prevention, has contributed to this achievement. However, the decline in age-adjusted mortality differs according to race, sex, and socioeconomic status with black individuals and lower-income populations sustaining the greatest impact of CVD, especially at younger ages. With one of the world's largest public health systems in terms of population coverage, Brazil has the means to implement actions to confront the high burden of CVD, focusing on health promotion and comprehensive care. Insufficient funding, low education levels, and social inequalities remain as the main barriers to be overcome. © 2016 American Heart Association, Inc.

    Paiva, Vanilda

    1995-05-01

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

    José Carlos Leite1; António José Dinis Ferreira2; Tanya Cristina de Jesus Esteves2; Célia Patrícia Martins Bento2 1Universidade Federal de Mato Grosso, Brazil; 2IPC - Escola Superior Agrária de Coimbra, Portugal Over the last three decades, deforestation in Brazil occurred systematically in the area known as the "arc of deforestation", an extensive geographical area located in the interface of the Cerrado and the Amazon biomes. This work encompasses the reasons, causes and/or motivations of that recent deforestation, focusing on the Central-West and Northern regions. A number of reasons will be presented, seeking to build an approach able to identify the deepest roots of deforestation of those regions. Our actions over the environment are framed by our cultural matrix that stream from a western philosophic attitude. This way, to understand the framework where the deforestation actions are justified requires a multidisciplinary approach to understand the deforestation of the Cerrado and Amazon biomes, since the motivations for forest destruction in Brazil are complex and not entirely understood within the domains of a single disciplinary area. To search for an isolated cause to understand the recent deforestation can only be plausible if we ignore information on what actually happens. The methodology used in this work is based on a bibliographical revision, analysis of georeferrenced information, participative processes implementation and observation of stakeholder behavior, and field research. It departs from a general vision on deforestation that initially occurred at the littoral region, by the Atlantic Rainforest, right after the arrival of the Europeans, and throughout the centuries penetrates towards the interior, hitting the Cerrado and Amazon biomes. In this last case, we focused on the Vale do Alto Guaporé region, near Bolivia, where the intensity of the deforestation was verified from 1970 to 1990. Ultimately, the final result is a mosaic of reasons

Often presented by authorities as a model for hydroelectric development because of the substantial power that it produces, the project's social and environmental impacts are also substantial. Examination of Tucurui reveals a systematic overestimation of benefits and underestimation of impacts as presented by authorities. Tucurui offers many as-yet unlearned lessons for hydroelectric development in Amazonia

  4. Class effects on racial inequality in Brazil

    Full Text Available This article analyzes the conditioning exercised by class inequality on racial inequality in income between whites and non-whites (the latter including both pardos, or mixed race, and pretos, or blacks in Brazil. The study uses linear regression techniques aimed at unveiling the "moderating" effect of class categories in the attenuation or exacerbation of race effects on personal income. There is a racial gap favoring whites in nearly all class categories, but its effect is significantly moderated by class condition. The racial gap in income is higher among middle-class positions and especially among managers. The proletarian segments per se display the lowest racial gaps in income.

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

    Based on the present knowledge of Brazilian Precambrian geology, an attempt is made to divide Precambrian rocks into different regions according to their favourability criteria for uranium concentrations. Paleozoic and Mesozoic occurrences are also mentioned. They are mainly associated with large sedimentary basins. Brazilian uranium occurrences can be grouped into the following environments: (1) Metaconglomerates; (2) Metasomatic rocks (associated with albitization); (3) Vein type; (4) Sandstone type and (5) Intrusive alkalic rock. Upper Proterozoicas folding regions related to mobile belts and large Precambrian unconformities are good targets for uranium exploration in Brazil. (Author) [pt

  13. Seismic risk map for Southeastern Brazil

    International Nuclear Information System (INIS)

    Mioto, J.A.

    1984-01-01

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

    2014-01-01

    The aim of this research is the measurement and assessment of individual differences of workaholism in Brazil, an important issue which affects the competitiveness of companies. The WART 15-PBV was applied to a sample of 153 managers from companies located in Brazil, 82 (53.6%) women and 71 (46.4%) men. Ages ranged from 20 to 69 years with an average value of 41 (SD=9.06). We analyzed, on one hand, the factor structure of the questionnaire, its internal consistency and convergent (with the Dutch Work Addiction Scale - DUWAS) and criterion validity (with General Health Questionnaire – GHQ). On the other hand, we analyzed individual gender differences on workaholism. WART15-PBV has good psychometric properties, and evidence for convergent and criterion validity. Females and males differed on Impaired Communication / Self-Absorption dimension. This dimension has a direct effect only on men’s health perception, while Compulsive tendencies dimension has a direct effect for both genders. The findings suggest the WART15-PBV is a valid measure of workaholism that would contribute to the workers’ health and their professional and personal life, in order to encourage adequate conditions in the workplace taking into account workers’ individual differences.

    The coal mines in Brazil are primarily located in southern part areas. The total coal reserves are approximately 32.8 billions tons, 89% of which are located in Rio Grande do Sul state. The Brazilian agriculture potentiality is very high, mainly due to the availability of flat land and the existence of industrial capacity to supply the main fertilizers needs. Electron beam flue gas treatment process ensures simultaneous removal of SO 2 and NO X from flue gases by single process, requiring no additional wastewater treatment system and can produce useful nitrogen fertilizer consisting of ammonium sulfate (NH 4 ) 2 SO 4 and ammonium nitrate NH 4 NO 3 as by-products. During the TC Project BRA/8/021 - Pilot Plant for Electron Beam Purification of Flue Gas supported by IAEA (1995-1996), a laboratory facility for electron beam flue gas treatment was set at IPEN. In 1997, an official request from Brazilian Government, Ministry of Science & Technology (MCT) and IPEN was made for the Japan Consulting Institute (JCI) to prepare feasibility studies of air pollution control by electron beam flue gas treatment in three power generation companies. These companies are responsible for the power generation, the transmission and the supply of electricity to Brazil: Jorge Lacerda – Eletrosul Centrais Eletricas do Sul do Brasil S.A., Presidente Medici – Companhia Estadual de Energia Eletrica (CEEE) and Piratininga – AES Eletropaulo Thermal Power Plants.

    Moreira, J.

    1995-01-01

    The present paper was prepared as a country study about the biomass potential for energy production in Brazil. Information and analysis of the most relevant biomass energy sources and their potential are presented in six chapters. Ethanol fuel, sugar-cane bagasse, charcoal, vegetable oil, firewood and other biomass-derived fuels are the objects of a historical review, in addition to the presentation of state-of-the-art technologies, economic analysis and discussion of relevant social and environmental issues related to their production and use. Wherever possible, an evaluation, from the available sources of information and based on the author's knowledge, is performed to access future perspectives of each biomass energy source. Brazil is a country where more than half of the energy consumed is provided from renewable sources of energy, and biomass provides 28% of the primary energy consumption. Its large extension, almost all located in the tropical and rainy region, provides an excellent site for large-scale biomass production, which is a necessity if biomass is to be used to supply a significant part of future energy demand. Even so, deforestation has occurred and is occurring in the country, and the issue is discussed and explained as mainly the result of non-energy causes or the use of old and outdated technologies for energy production.

    Full Text Available Abstract Introduction The incidence of lip, oral cavity and oropharynx cancer in Brazil is one of the highest worldwide. Objective This study aimed to identify predictors for oral cancer in Brazil between 2010 and 2013. Method Through a time series study in which 14,959 primary head and neck cancer diagnoses were evaluated. The variables of interest were gender, age, race, education level, family history of cancer, alcohol consumption, smoking, and previous cancer diagnosis. The outcome variable was divided into “oral cancer” and “cancer of other head and neck regions.” The data were analysed by multiple binary logistic regression; α=5%. Result The protective factor was: approximately 12 years of education (OR = 0.85. The risk factors were: being an ex-consumer (OR=1.19 or consumer (OR=1.11 of alcohol, tobacco use (OR=1.35 and a prior diagnosis of cancer that went untreated (OR=1.21. Conclusion Was concluded that the oral cancer had the following predictors compared to other types of head and neck cancer during the same period: approximately 12 years of education (protective factor and ex-consumer or consumer of alcohol, smoking and previous diagnosis of cancer that went untreated (risk factors.

  18. The elimination of Chagas' disease from Brazil.

    2008-09-01

    On 9 June 2006 the Pan American Health Organization (PAHO) presented the Minister of Health of Brazil with the International Elimination of Transmission of Chagas' Disease Certificate. This act was the culmination of an intensive process that began in 1991 with the Southern Cone Initiative, a joint agreement between the governments of Argentina, Bolivia, Brazil, Chile, Paraguay, Uruguay and Peru, to control Chagas' disease by the elimination of the main vector, Triatoma infestans. This initiative has been highly successful and the prevalence area of the vector diminished rapidly in the last years. As a consequence, the current seroprevalence in children aged between 0 and 5 years is of the order of 10(-5), a clear indication that transmission, if it is occurring, is only accidental. In this review I calculate the basic reproduction number, R0, for Chagas' disease and demonstrate that its relatively low value (1.25) explains why vectorial transmission was interrupted relatively easily. In addition, I used a mathematical model to forecast how long the remaining cases of the disease, as well as the additional vertically transmitted cases will last.

  19. Antifouling activity of twelve demosponges from Brazil

    Directory of Open Access Journals (Sweden)

    SM. Ribeiro

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

    Brazil has become a global leader in the production of commodity row crops such as soybean, sugarcane, cotton, and corn. Here, we employ 30m spatial resolution Landsat data to estimate cropland extent in the year 2000 and its subsequent expansion through 2014. A probability-based sample of reference data allows us to report unbiased estimates of national, biome, and state-scale area of crop expansion with associated uncertainties. We find an increase in Brazilian cropland extent from 26.0 Mha in 2000 to 46.1 Mha in 2014. The cropland frontier states of Maranhao, Tocantins, Piaui, Bahia (MATOPIBA), Mato Grosso, Mato Grosso do Sul, and Para all more than doubled in cropland extent. The states of Goias, Minas Gerais and Sao Paulo experienced >50% increases. The vast majority of expansion, 79%, occurred on repurposed pasture lands, and 20% from the conversion of natural vegetation. Area of converted Cerrado savannas was nearly 2.5 times that of Amazon forests, and accounted for over half of new cropland in MATOPIBA. Spatio-temporal dynamics of cropland expansion are reflected in market conditions, land use policies, and other factors. Continued extensification of cropland is a viable option across Brazil with attendant benefits for and challenges to development.

  1. Paragonimiasis: first case reported in Brazil

    Directory of Open Access Journals (Sweden)

    Antônio Carlos Moreira Lemos

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

  2. Main aspects of sunflower production in Brazil

    Directory of Open Access Journals (Sweden)

    Castro Cesar

    2018-01-01

    Full Text Available Sunflower is one of the most important oilseed crops in the world, since its grains have high oil content (38% to 50%, primarily used for the production of high quality oil. The production of sunflower increases the supply of protein meal for animal feeding, which enables the increase of protein production, more specifically meat, eggs and milk. Grain production systems in Brazil have peculiarities, since two to three different crops are grown in a special arrangement, in the same area and year. Notwithstanding the small cultivated area in Brazil of 62.3 thousand hectares, sunflower is used in succession or rotation with other grain crops such as soybean or maize, showing an enormous potential for expansion and can be cultivated from latitudes 33°S to 5°N, especially in the Brazilian Cerrado biome. Sunflower cultivation in succession to soybean as a second summer crop can also reduce environmental impacts because of the more efficient usage of production factors, such as land and sharing of agricultural inputs, machinery, infrastructure and workforce. The success of establishing the sunflower is associated with the adequate management of soil fertility, use of cultivars adapted to different environments, plant arrangement, seed quality and adequate phytosanitary management, among other factors. It also needs strategic actions, planning and, long-term research and technology diffusion.

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

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

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

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

    Brazil's economic situation is responsible for an urgent demand for energy. There are several ways to generate energy, in some localities of our country, energy generation occurs almost exclusively by nuclear route, as in Rio de Janeiro state. Brazil has the sixth largest reserve of the uranium ore in the world. Nowadays there is only one mine under exploration (Uraniferous District of Lagoa Real - Caetite-BA). Unfortunately, nuclear power generation is better known, by common citizen, more for its unwanted effects than for its benefits. This fact is also powered by some Non-Governmental Organizations (NGOs), such as Greenpeace, who claim the uranium mine is dangerous since it causes environmental contamination. However, Industrias Nucleares do Brasil (INB) rejected these accusations. In a previous study, we demonstrated that doses of the Caetite (BA) population are consistent with those usually found in other countries. We stated also the higher concentration of 238 U determined, in only one water sample, is probably due to natural processes, as soil leaching. In order to verify the existing natural processes, macro and micro chemical elements present in water and soil samples collected in the Caetite (BA) region were determined by ICP-MS. The results were transformed into dendrograms where chemical correlations are evidenced and they are consistent with existing natural chemical processes. It was also possible to observe a correlation between samples corroborating with the Geographic Information Systems data to be presented in this same scientific event. (author)

    Brazil's economic situation is responsible for an urgent demand for energy. There are several ways to generate energy, in some localities of our country, energy generation occurs almost exclusively by nuclear route, as in Rio de Janeiro state. Brazil has the sixth largest reserve of the uranium ore in the world. Nowadays there is only one mine under exploration (Uraniferous District of Lagoa Real - Caetite-BA). Unfortunately, nuclear power generation is better known, by common citizen, more for its unwanted effects than for its benefits. This fact is also powered by some Non-Governmental Organizations (NGOs), such as Greenpeace, who claim the uranium mine is dangerous since it causes environmental contamination. However, Industrias Nucleares do Brasil (INB) rejected these accusations. In a previous study, we demonstrated that doses of the Caetite (BA) population are consistent with those usually found in other countries. We stated also the higher concentration of {sup 238}U determined, in only one water sample, is probably due to natural processes, as soil leaching. In order to verify the existing natural processes, macro and micro chemical elements present in water and soil samples collected in the Caetite (BA) region were determined by ICP-MS. The results were transformed into dendrograms where chemical correlations are evidenced and they are consistent with existing natural chemical processes. It was also possible to observe a correlation between samples corroborating with the Geographic Information Systems data to be presented in this same scientific event. (author)

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

    1996-01-01

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

    Much concern has been expressed lately about the decline of teaching and research activities in radiochemistry in many countries, as was discussed in an IAEA Technical Meeting in Antalya, Turkey, in 2002, and also at MTAA-11 in Guildford, UK. In the IAEA meeting, a survey was presented about the current situation in different regions of the world (Eastern Europe, East and West Asia, Africa, North America and Latin America) by experts of each region. In the case of Brazil, which has nuclear research reactors and also cyclotrons in operation, the teaching and research activities in radiochemistry are concentrated in the three main institutes of the Brazilian Nuclear Energy Commission, in the University of Sao Paulo and in other universities, in different regions of the country. In the present paper, a closer look is given to the radiochemistry teaching and research activities that are being conducted nowadays in Brazil, comprising: number of radiochemistry courses and students being formed, main research areas being conducted, as well as research and production of radioisotopes for nuclear medicine, using nuclear reactors and cyclotrons.

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

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

    Dengue virus, commonly transmitted by mosquitoes, causes a human disease of significant social impact and presents a serious public health problem in Brazil. This report describes the unusual emergence of DENV-4 in northern Brazil after a nearly 30-year-long absence. DENV-4 genotype I is of Asian origin and was identified in the serum of patients receiving treatment at a hospital serving the Salvador area (Brazilian state of Bahia). The identification of dengue virus serotypes through molecular and phylogenetic analysis is essential for predicting disease severity or fatal illness, principally in endemic countries such as Brazil.

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

    Full Text Available Public policy initiatives aimed at prostitution have undergone changes since the end of the 20th century. They are no longer the exclusive objective of police intervention and hygienic concerns, and have come to include the perspective of prostitutes themselves. In Brazil, it is possible to identify legislative initiatives in the field of healthcare that refer to labor and human rights in this field. The purpose of this article is to examine two of these initiatives: Proposed Law n. 98/2003, presented by federal deputy Fernando Gabeira to recognize prostitution as a “service of a sexual nature” and the labor legislation that sought to insert the activity of sex professionals within the Brazilian Classification of Occupations.

    This paper presents the management characteristics of charity hospitals in Brazil, based on data from a national survey developed in 2001. The sample accounted for the random inclusion of 66 Brazilian Unified Health System (SUS) inpatient care providers with less than 599 beds and all 26 hospitals with at least 599 beds. It also included 10 institutions assumed as non-providers of services to the SUS. The analyses are descriptive, focusing on the classification of the hospitals according to their managerial development level, as well as selected issues regarding the utilization of specific managerial technologies, human resources, technical services, and services contracting. Distinct managerial levels were identified, but it is important to note that 83% of the SUS providers with less than 599 beds were classified as having incipient management. The authors discuss implications of the findings for inpatient care policies, considering the importance of charity hospitals for the Brazilian Health System.

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

    2006-08-01

    A generic drug policy has been implemented in Brazil since 1999. Several political and administrative stages transpired between enactment of the legislation and the actual marketing and consumption of these drugs. This article describes the policy implementation process and examines the country's generic drug legislation, approved from 1999 to 2002. To contextualize these measures, the study compares articles published by two national periodicals and interviews with a government representative involved in drafting the legislation and a representative from the pharmaceutical industry. Generic drugs quickly gained considerable space in the Brazilian pharmaceutical market. Ongoing adaptation of the legislation, media support, and the government's involvement in spreading the policy were key success factors. The population's access to medicines did not increase significantly, but people can now purchase medicines at more affordable prices and with quality assurance and interchangeability.

  4. Comments on human eurytremiasis in Brazil.

    Pinto, Hudson Alves; de Melo, Alan Lane

    2016-05-20

    Eurytremiasis is an important parasitic disease of cattle that was recently suggested to be a neglected and emerging human disease in Brazil. Based on a misinterpretation of the life cycle of the parasite, it was suggested that a great number of people could be infected with this fluke in the country. In the present letter, aspects of the life cycle of Eurytrema spp. are revisited and clarified. The mechanism of transmission previously reported for the few accidental human cases involved the ingestion of raw or undercooked insects (grasshoppers and crickets) harboring the infective metacercariae. In reality, the zoonotic potential of Eurytrema species is extremely low, and human eurytremiasis is not, and probably never will be, a zoonotic disease in countries where entomophagy is not a common food habit.

  5. Forecasting about petroleum exploration in Brazil

    International Nuclear Information System (INIS)

    Bacoccoli, G.

    1987-01-01

    Scenarios with increasing petroleum demand in the next decade lead to an expectation of increasing consumption per capita in Brazil, but still lower than in developed countries. Without additional discoveries, the nation would reach the mid nineties with the necessity of importing one million barrels of petroleum/day, which would cost nearly thirty dollars a barrel, according to forecasts. Even with an assumed growth, the nation's economy hardly would resist an annual expenditure over ten billion dollars with petroleum imports. If the petroleum resources of the aggregate Albacora/Marlim fields is added to both the resources to be discovered by 1995 and the petroleum resources to be incorporated to the reserves by improving recovery factors of known fields, it is anticipated that dependency on imports could be reduced by 50%, or even eliminated. Therefore, it is mandatory to maintain the rhythm of investment in exploration and production of Brazilian petroleum. (author)

    2007-01-01

    This study reviews the history of the national anti-asylum struggle in Brazil. It analyzes some of the movement's difficulties, achievements and challenges. The theory of social movements is used here as an important analytical tool to understand this collective action, to the degree in which theory allows an appraisal of this type of social action rooted in its many configurations, evidencing the complexity of the contemporary world. The anti-asylum movement is composed of many stakeholders whose struggles and conflicts have been developed through different social-political-institutional dimensions. It encompasses at different moments and to different degrees, a movement which articulates solidarity and conflict relations and social denunciations in an attempt to transform relations and conceptions that are discriminatory and which are intended to control the "insane" and "insanity" in our country.

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

    2005-01-01

    In recent years, the concept of producing biodiesel from renewable lipid sources has regained international attention. In Brazil, a national program was launched in 2002 to evaluate the technical, economic, and environmental competitiveness of biodiesel in relation to the commercially available diesel oil. Several research projects were initiated nationwide to investigate and/or optimize biodiesel production from renewable lipid sources and ethanol derived from sugarcane (ethyl esters). Once implemented, this program will not only decrease our dependence on petroleum derivatives but also create new market opportunities for agribusiness, opening new jobs in the countryside, improving the sustainability of our energy matrix, and helping the Brazilian government to support important actions against poverty. This article discusses the efforts to develop the Brazilian biodiesel program in the context of technical specifications as well as potential oilseed sources.

    This text describes the present status of fast reactor activities in Brazil, emphasizing the strategies being used to preserve this reactor concept as a viable alternative for future electricity generation in the country. The program is mostly research-oriented and has the objective of establishing a consistent knowledge basis which can serve as a support for the transition to the activities more directly related to design, construction and operation of an experimental fast reactor. Due to the present economic difficulties, the program is still modest but it is gradually growing. A report which has been finalized in December, 1995 and submitted to the authorities indicates the existence of the grounds for enlarging and consolidating the program. (author)

    2008-01-01

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

(226)Ra, (228)Ra, (40)K, (238)U and (232)Th were determined in PG, soils and sediment samples by gamma spectrometry using the hyper pure germanium detector and neutron activation. The migration of radionuclides in the phosphogypsum profile did not show the same behavior for all sampling sites. The mean activity concentration of (226)Ra was 95 Bq kg(-1), which is far below the limit recommended by the U.S. Environmental Agency (USEPA) for its application in agriculture (370 Bq kg(-1)) and the Brazilian Commission of Nuclear Energy Resolution 113 that established a reference level of 1000 Bq kg(-1) of (226)Ra or (228)Ra for the use of PG in agriculture as well as building materials.

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

    Ireland, Timothy D.

    2008-11-01

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

    2017-11-01

    The Pantanal is a hotspot for arbovirus studies in South America. Various medically important flaviviruses and alphaviruses have been reported in domestic and wild animals in the region. To expand the knowledge of local arbovirus circulation, a serosurvey for 14 Brazilian orthobunyaviruses was conducted with equines, sheep and free-ranging caimans. Sera were tested for specific viral antibodies using plaque-reduction neutralization test (PRNT). Monotypic reactions were detected for Maguari, Xingu, Apeu, Guaroa, Murutucu, Oriboca, Oropouche and Nepuyo viruses. Despite the low titers for most of the orthobunyaviruses tested, the detection of monotypic reactions for eight orthobunyaviruses suggests the Pantanal as a region of great orthobunyavirus diversity. The present data, in conjunction with previous studies that detected a high diversity of other arboviruses, ratify the Pantanal as an important natural reservoir for sylvatic and medically important arboviruses in Brazil.

They include plateaus, waterfalls, beaches, sand dunes, native forests, mountains and other attractions in regions that are home to poor populations struggling to make their living on smallholder agriculture and that frequently do not have their land rights guaranteed. Implementing ecotourism in these regions can mean environmental preservation and a more sustainable livelihood for the local population. The government has a fundamental role to leverage this activity, providing the means to stimulate sustainable forms of agriculture and infrastructure construction parallel to ecotourism. It is also important to train community members to ensure environmental preservation and well serve the visitors, in addition to implementing measures such as waste recycling and efficient water use.

    The most recent research in the area of cosmetics to sustainability has focused on obtaining formulations rich in nontraditional oils and butters from seeds and fruits native to Brazilian tropical flora. These have contributed to aggregate value for the raw materials and involvement of small farms forming rural production in Brazil, since the plants are cultivated in preservation areas sponsored by companies who are partners in the Government Program for Brazilian Sustainability. Given that the oils extracted from seeds have the potential to replace these cutaneous constituents, it has been verified that new products of strong commercial impact show an increasing tendency to incorporate in their formulas the oils of plants grown in Brazilian soil.

  20. The challenges of ageism in Brazil

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

    1979-05-01

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

    Nineteen taxa of Mucorales, belonging to Absidia, Apophysomyces, Cunninghamella, Fennellomyces, Lichtheimia, Mucor, Mycotypha, Rhizopus and Syncephalastrum were isolated from 36 composite soil samples in three semiarid areas in the State of Pernambuco (Triunfo, Cabrobó and Belém de São Francisco), Northeast Brazil, which are characterized by Caatinga vegetation. Triunfo is preserved, whereas Cabroró and Belém de São Francisco are experiencing low and severe desertification processes, respectively. Mucorales were isolated in Petri dishes in triplicate from 5 mg samples of soil placed on the surface of wheat germ agar plus chloramphenicol and Cercobin [Dimethyl 4,49-(103 phenylene) bis (3-thioallophanate)] medium. The plates were left on a bench at room temperature (28 ± 2 °C) for 72 h of alternating dark and light periods. Absidia cylindrospora presented the highest amount of CFU/g of soil, followed by L. hyalospora, C. phaeospora and C. echinulata var. echinulata. The latter, and R. microsporus var. microsporus, presented the highest frequencies of occurrence. Soils from Triunfo showed higher diversity of Mucorales than the samples from the other areas, although without differing statistically in relation to species richness. The communities of Mucorales from the degraded areas were more similar, while that from the preserved area was quite different. Most of the identified specimens have been commonly isolated from soil in other Brazilian regions, which indicates that they are not endemic of the semiarid. Eleven taxa are registered for the first time in this ecosystem, while F. heterothallicus is reported for the first time in Brazil. PMID:24159320

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

    To determine the relationship between pacifier use and the duration of exclusive breast-feeding in the first six months of age, among poor children with unfavourable birth weight, from an underdeveloped region in Brazil. Prospective cohort study with infants followed from birth to 6 months of age. Healthy children born with unfavourable birth weight (pacifier use at 1st and 6th month of age. Data were collected at maternity hospitals and during home interviews, using structured questionnaires, by trained data collectors unaware of the study aims, and analyzed using survival analysis and the Cox Proportional Hazard Model. 500 children were enrolled and 13% were lost to follow up at the 1st month. Most of the families had a monthly income less than five times the minimum wage. One third of the mothers were adolescents, one fifth were working outside the home by the 6th month and most attended prenatal care visits. Approximately 60% of the children were using pacifiers by the 1st month. The average number of days for exclusive breast-feeding for pacifier use by the 6th month was 125.3 compared to 87.0 among non-users (p=0.0001). Children using pacifiers were 1,9 more likely to have stopped exclusive breastfeeding by the 6th month compared to non-users, even after controlling potential confounders. Pacifier use was associated with the early termination of breast-feeding in Brazil, among poor children with unfavourable birth weight, living in an underdeveloped area. As a possible marker of early weaning, pacifier use can help health workers identify those mothers in need of extended counselling to reinforce breast-feeding practices.

    Exclusive breastfeeding (EBF) rates for infants younger than 6 months have increased in Brazil, although at the current pace of improvement it would take 6 years to reach an EBF rate of 50%. Thus, it is important to identify relevant modifiable key risk factors for the premature interruption of EBF. This study aimed to find out if pacifier use is an independent risk factor for the interruption of EBF among Brazilian infants. We conducted secondary cross-sectional data analyses of 2 waves of infant feeding surveys conducted in 1999 and in 2008 in the Brazilian state capitals and Federal District (N = 42 395 children pacifier use and the risk of interruption of EBF in a pooled sample and within each survey wave, adjusting for socioeconomic, demographic, and biomedical confounders. In the pooled sample, a third of the infants were exclusively breastfed (32.7%) and almost 50% had used a pacifier. Whereas EBF prevalence among infants increased from 25.1% in 1999 to 40.3% in 2008, pacifier use prevalence decreased from 58.5% to 41.6% in the same time period. Pacifier use was strongly associated with the risk of interruption of EBF in 1999 (adjusted odds ratio [AOR] = 2.65; 95% confidence interval [CI], 2.38-2.94), in 2008 (AOR = 3.18; 95% CI, 2.81-3.60), and in the pooled sample (AOR = 2.77; 95% CI, 2.63-2.91) after adjusting for key confounders. Pacifier use was the strongest risk factor for EBF interruption. Effective strategies to reduce pacifier use among infants younger than 6 months may further improve EBF rates in Brazil. © The Author(s) 2015.

    Successive studies attempting to clarify national aspects of ethanol demand have assisted policy makers and producers in defining strategies, but little information is available on the dynamic of regional ethanol markets. This study aims to analyze the characteristics of ethanol demand at the regional level taking into account the peculiarities of the developed center-south and the developing north-northeast regions. Regional ethanol demand is evaluated based on a set of market variables that include ethanol price, consumer's income, vehicle stock and prices of substitute fuels; i.e., gasoline and natural gas. A panel cointegration analysis with monthly observations from January 2003 to April 2010 is employed to estimate the long-run demand elasticity. The results reveal that the demand for ethanol in Brazil differs between regions. While in the center-south region the price elasticity for both ethanol and alternative fuels is high, consumption in the north-northeast is more sensitive to changes in the stock of the ethanol-powered fleet and income. These, among other evidences, suggest that the pattern of ethanol demand in the center-south region most closely resembles that in developed nations, while the pattern of demand in the north-northeast most closely resembles that in developing nations. - Research highlights: → Article consists of a first insight on regional demand for ethanol in Brazil. → It proposes a model with multiple fuels, i.e., hydrous ethanol, gasohol and natural gas. → Results evidence that figures for regional demand for ethanol differ amongst regions and with values reported for national demand. → Elasticities for the center-south keep similarities to patterns for fuel demand in developed nations while coefficients for the north-northeast are aligned to patterns on developing countries.

    To evaluate the prevalence of spontaneous and induced abortion reported by a sample of Brazilian women interviewed in the National Demographic Health Survey of 1996. This was a secondary analysis of the Brazilian DHS-96 database, with information from interviews with a representative sample of 12,612 women about their reproductive life, focusing on the prevalence of spontaneous and induced abortion in the last five years and the associated factors for the various regions of the country and for Brazil as a whole. The sampling method was implemented with a strategy selection in two stages, one for the households and the other for women. The prevalence of spontaneous and induced abortion was estimated for Brazil and regions, and the socio-demographic characteristics of the women were analyzed as a function of the abortion's experience. A multinomial regression model analysis was used for the identification of factors independently associated with both types of abortion; their OR and respective 95% CI are reported. The prevalence of reported spontaneous abortion was 14% and the prevalence of induced abortion was 2.4% for the country as a whole. The state with the highest prevalence of induced abortion was Rio de Janeiro with 6.5%, followed by the Northeast region with 3.1%. The places with the lowest prevalence were the state of São Paulo and the South region. Both spontaneous and induced abortion showed higher prevalences with increasing age of the women studied. Being from the urban area (OR=1.5; 95%CI=1.0-2.3), having had more than one live child (OR=2.2; 95%CI=1.5-3.2) and being non-white (OR=1.4; 95%CI=1.0-1.8) were the main risk factors for induced abortion. The non-modifiable risk factors for induced abortion identified in this study indicate the need for improvement of educational and contraceptive actions, with priority for these specific demographic groups.

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

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

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

  14. Phillips curve in Brazil: an unobserved components approach

    2014-12-01

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

    1992-01-01

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

    After years of boom, Brazil will experience a recession this year. There was a significant imbalance in recent years from a budgetary point of view, inflation and foreign exchange. Protectionist Brazilian policy don't support foreign trade. Therefore consumers in the current recessive market environment are more willing to work with so-called collaborative consumption, even though Brazil is a country with one of the highest crime rate and the level of trust of consumers is lower than in other...

    2017-08-01

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

  17. Governance and pharmacovigilance in Brazil: a scoping review.

    Moscou, Kathy; Kohler, Jillian C; MaGahan, Anita

    2016-01-01

    This scoping review investigates the relationship between governance, pharmacovigilance, and Agencia Nacional de Vigilancia Sanitaria (ANVISA) in Brazil, which has authority over Brazil's national pharmaceutical policy, drug registration and coordination of the national pharmacovigilance system. The purpose is to investigate opportunities for effective pharmacovigilance. Sixty-three terms pertaining to pharmacovigilance in Brazil and ANVISA, global institutions, pharmaceutical industry, and civil society were searched in thirteen relevant databases on November 17-18, 2013. Using a pharmacogovernance framework we analyzed ANVISA's pharmacogovernance: the manner in which governing structures, policy instruments, and institutional authority are managed to promote societal interests for patient safety due to medication use. The integration of transnational policy ideas for regulatory governance into pharmacogovernance in Brazil was also investigated. Brazil's policy, laws, and regulations support ANVISA's authority to ensure access to safe medicines and health products however ANVISA's broad mandate and gaps in pharmacogovernance account for regional disparities in monitoring and assessing drug safety. Gaps in pharmacogovernance include: equity and inclusiveness; stakeholder coordination; effectiveness and efficiency; responsiveness; and intelligence and information. Pharmacogovernance that addresses 1) regional resource disparities, 2) federal and state lack of coordination of pharmacovigilance regulations, 3) asymmetric representation in the pharmaceutical regulatory agenda and which 4) disaggregates regulatory authority over health and commercial sectors would strengthen pharmacovigilance in Brazil.

    1994-01-01

    This is an X-band image showing seasonal changes at the hydrological test site of Bebedouro in Brazil. The image is centered at 9 degrees south latitude and 40.2 degrees west longitude. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on April 10, 1994, during the first flight of the radar system, and on October 1, 1994, during the second mission. The swath width is approximately 16.5 kilometers (10.5 miles) wide. The image channels have the following color assignments: red represents data acquired on April 10; green represents data acquired on October 1; blue corresponds to the ratio of the two data sets. Agriculture plays an important economic and social role in Brazil. One of the major problems related to Brazilian agriculture is estimating the size of planting areas and their productivity. Due to cloud cover and the rainy season, which occurs from November through April, optical and infrared Earth observations are seldom used to survey the region. An additional goal of monitoring this region is to watch the floodplains of rivers like Rio Sao Francisco in order to determine suitable locations for additional agricultural fields. This area belongs to the semi-arid northeastern region of Brazil, where estimates have suggested that about 10 times more land could be used for agriculture, including some locations which could be used for irrigation projects. Monitoring of soil moisture during the important summer crop season is of high priority for the future development and productivity of this region. In April the area was covered with vegetation because of the moisture of the soil and only small differences could be seen in X-band data. In October the run-off channels of this hilly region stand out quite clearly because the greenish areas indicated much less soil moisture and water content in plants.

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

    2013-05-01

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

    The Brazil Current system off Cabo Frio (latitude 23°S) was continuously monitored by underwater gliders between March 2013 and July 2015. The gliders navigation followed 100-km long sections normal to the shelf break. The mean time to complete a section length was 5 days, which was considered synoptic for the purpose of the study, and allowed the computation on a weekly basis. We analyzed the seasonal pattern of the geostrophic current, mass transport and water masses occurrence in the region. At least one transect per month was considered valid as a normal section of the Brazil Current system down to 1000 m depth. Temperature and salinity profiles from the CT-sail installed on the gliders were used to compute relative geostrophic velocity profiles. Instead of assuming an arbitrary level of no motion, absolute geostrophic velocities were estimated referencing the relative profiles to the surface geostrophic velocities derived from satellite altimetry data. An intensification of the southward flow during spring and summer was observed with maximum cross-section velocities frequently higher than 0.3 m/s. Autumn and winter maximum cross-section velocities reached 0.2 m/s on average. The characteristic shear depth between the southward flow of the Brazil Current and the northward flow of the Intermediate Current varied around 300 to 500 meters with seasonal behavior (deeper in autumn/winter, shallower during spring/summer). A cyclic behaviour of the South Atlantic Central Water was also observed, with both top and bottom rising during spring/summer and submerging in autumn/winter, keeping an average thickness of 400 m. The Cabo Frio eddy was present in different moments throughout the observed period with impact over the transport in the region. For the first time a synoptic data series longer than 2 years was produced using autonomous vehicles to study the Brazil Current. Early data obtained by traditional ship-based observations are sparse in space and time. The

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

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

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

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

    The mining, milling and processing of uranium and thorium bearing minerals may result in radiation doses to workers. A preliminary survey pilot program, that included six mines in Brazil (two coal mines, one niobium mine, one nickel mine, one gold mine and one phosphate mine), was launched in order to determine the need to control the radioactive exposure of the mine-workers. Our survey consisted of the collection and analysis of urine samples, complemented by feces and air samples. The concentrations of uranium, thorium and polonium were measured in these samples and compared to background data from family members of the workers living in the same dwelling and from residents from the general population of Rio de Janeiro. The results from the coal mines indicated that the inhalation of radon progeny may be a source of occupational exposure. The workers from the nickel, gold and phosphate mines that were visited do not require a program to control internal radiological doses. The niobium mine results showed that in some areas of the industry exposure to thorium and uranium might occur. (author)

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

    The objective of this study was to estimate the household availability of fibers in Brazil and to identify the dietary sources of this nutrient. Data from the 2008-2009 Household Budget Survey were used to estimate national household availability and density of fibers and also according to stratifications defined by income level, five regions and area (rural or urban). The contribution of the different food groups, classified by the nature, extent and purpose of processing, to total fibers available in Brazilian households was also determined. The mean density of per capita fibers was 7.6 g/1000 kcal. Higher availability and density of fibers was observed in households situated in rural areas and among low-income families. The main dietary sources of fiber were beans, bread, rice, fruit, vegetables and manioc flour. Fiber intake was found to be insufficient. Therefore, actions promoting a healthy diet are needed to improve the dietary quality of the Brazilian population. Copyright © 2014 Elsevier Ltd. All rights reserved.

Data from these sources were compared using descriptive statistics and the Percentage error. Results: The data values made available by the Internet platform differed from those obtained from the vaccination rooms, with a Percentage error relatively to the actual values in the range [-0.48; 0.39]. Concordant values were observed only in one among the sixty analyzed months (1.66%. Conclusions: A frequent and large difference between the number of diphtheria and tetanus toxoids and pertussis vaccine doses administered in the two levels was detected.

    Full Text Available Proformação is a distance teacher certification course aimed at providing training to 27,000 uncertified teachers in 15 Brazilian states. This innovative program organizes human and technical resources for delivering distance education in a cost-effective manner. Different from other institutional systems – which typically employ their own dedicated content, design, and instructional resource personnel, and accompanied by a large pool of administrative staff – Proformação leverages pre-existing learning resources such as content experts, technology specialists, instruction, and student support systems from several institutions. Proformação goal is to create a viable teacher certification course to upgrade thousands of non-certified teachers working in the field. Proformação is coordinated by an administrative unit of the Brazilian Ministry of Education. To support the program, an information system was implemented to continuously and consistently monitor the program’s activities and results. Results of an external evaluation have been positive; Proformação is regarded by some as an innovative model for delivering decentralized training opportunities to large student numbers. Therefore, the findings in this article may prove interesting to those charged with implementing distance learning initiatives in developing countries, in that the lessons learned in Brazil may help others interested in implementing similar distance training programs.

    Radiocarbon Accelerator Mass Spectrometry is an ultra-sensitive technique that enables the direct measurement of carbon isotopes in samples as small as a few milligrams. The possibility of dating or tracing rare or even compound specific carbon samples has application in many fields of science such as Archaeology, Geosciences and Biomedicine. Several kinds of material such as wood, charcoal, carbonate and bone can be chemically treated and converted to graphite to be measured in the accelerator system. The Physics Institute of Universidade Federal Fluminense (UFF), in Brazil will soon be able to perform the complete 14 C-AMS measurement of samples. At the Nuclear Chronology Laboratory (LACRON) samples are prepared and converted to carbon dioxide. A stainless steel vacuum system was constructed for carbon dioxide purification and graphitization is performed in sealed tubes in a muffle oven. Graphite samples will be analyzed in a 250 kV Single Stage Accelerator produced by National Electrostatic Corporation which will be installed in the beginning of 2012. With the sample preparation laboratory at LACRON and the SSAMS system, the Physics Institute of UFF will be the first 14 C-AMS facility in Latin America. (author)

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

    2016-06-01

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

    Fish larvae of 'corvinas' (Pachyurus bonariensis and Plagioscion ternetzi) from Sinhá Mariana Lagoon, Mato Grosso State, were collected from March 2000 to March 2004, in order to determine the parasitic fauna of fishes. Larvae from the two species were parasitized by the same endoparasites: Contracaecum sp. Type 2 (larvae) (Nematoda: Anisakidae) in the mesentery and Neoechinorhynchus (Neoechinorhynchus) paraguayensis (Acanthocephala: Neoechinorhynchidae) in the stomach and the terminal portion of the intestine. Statistical analysis showed that there was a significant positive correlation between the standard length of hosts and the abundance of acanthocephalans and nematodes, and that the prevalence of nematodes presented a significant positive correlation with the standard length of the two species of hosts, indicating the presence of a cumulative process of infection. The present study constitutes the first record of nematodes and acanthocephalans parasitizing larval fish, as well as the first record of endoparasites in fish larvae in Brazil. In addition, it lists a new locality and two species of hosts for Contracaecum sp. Type 2 (larva) and N. (N.) paraguayensis.

    The Amazon region of Brazil is endemic for malaria. In the State of Santa Catarina, malaria was eliminated in the 1980s. Since then, a few sporadic isolated autochthonous cases have occurred. However, because malaria vectors are present within Brazilian territory and extensive endemic areas exist in this country, along with the great mobility of people in tourist areas of Santa Catarina, there is the likelihood of reintroduction of the disease. The following data were used: the database of the Entomology Group of the National Health Foundation, Santa Catarina (ACCES, 1997-2000); the epidemiological surveillance information system of the Health Surveillance Department (Malaria/SC); and the notifiable disease information system (SINAN/SC). These data were transferred to and analyzed in the Microsoft Office Excel 2007 software. Collections were carried out in 48 municipalities and 159 localities, and 12,310 culicids, 11,546 anophelines (93.7%) and 764 others (6.2%) were identified. Three subgenera and 13 species of anophelines were identified. Given that in the municipalities investigated, important vectors such as Anopheles cruzii and Anopheles albitasis were found to be present, with movements of infected individuals from endemic areas, these areas can be considered to be receptive and vulnerable to malaria. These species are suspected of being responsible for malaria transmission in this region, especially in the municipalities of Gaspar, Indaial and Rodeio.

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

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

  3. Perspectives for Sustainable Aviation Biofuels in Brazil

    2015-01-01

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

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

    Evaluation of users' satisfaction with the health system brings back longstanding questions concerning the quality of services provided to the Brazilian population. The current study analyzes satisfaction with outpatient and inpatient care based on the results of the World Health Survey, conducted in Brazil in 2003. To explain satisfaction with various aspects of care through a small number of factors, the factor analysis technique was used, through principal components analysis (PCA). Multiple regression models identified associations between satisfaction scores and different sociodemographic variables. For outpatient care, waiting time showed the lowest degree of satisfaction, and in the case of hospitalization, freedom to choose the physician was the worst evaluated aspect. Three components were extracted from the PCA, related respectively to satisfaction with health professionals, health services, and health problem solution. Multiple regression analysis showed that having experienced some type of discrimination (on the basis of gender, age, poverty, social class, skin color, or type of disease) and being an exclusive user of the public National Health System involved a lower degree of users' satisfaction.

  6. Anthropotechnological analysis of industrial accidents in Brazil.

    1999-01-01

    The Brazilian Ministry of Labour has been attempting to modify the norms used to analyse industrial accidents in the country. For this purpose, in 1994 it tried to make compulsory use of the causal tree approach to accident analysis, an approach developed in France during the 1970s, without having previously determined whether it is suitable for use under the industrial safety conditions that prevail in most Brazilian firms. In addition, opposition from Brazilian employers has blocked the proposed changes to the norms. The present study employed anthropotechnology to analyse experimental application of the causal tree method to work-related accidents in industrial firms in the region of Botucatu, São Paulo. Three work-related accidents were examined in three industrial firms representative of local, national and multinational companies. On the basis of the accidents analysed in this study, the rationale for the use of the causal tree method in Brazil can be summarized for each type of firm as follows: the method is redundant if there is a predominance of the type of risk whose elimination or neutralization requires adoption of conventional industrial safety measures (firm representative of local enterprises); the method is worth while if the company's specific technical risks have already largely been eliminated (firm representative of national enterprises); and the method is particularly appropriate if the firm has a good safety record and the causes of accidents are primarily related to industrial organization and management (multinational enterprise).

    Full Text Available This paper aimed to describe milk production in Southern Rio Grande do Sul state, Brazil, and to identify factors that affect milk quality at this region. The average age of regional dairy farmers is 49, and 67.9% has not concluded elementary school. Dairy farming is carried out on properties with an average of 26.06 hectares and 8.4 lactating cows. Most of them (32.83% yield 50 to 100 L/day. Among the properties, 13.21% yield up to 30 L/day, and only 1.89% produces over 500 milk liters a day. Average yield was 6.8 L/day. Regarding to milking procedure, 39.3% farmers milk manually the animals, only 14.2% performed pre-milking teat disinfection, and 53.9% uses a single cloth to dry all animal teats. For infrastructure, 52.8% milks animals in wooden cowsheds. We observed that the average somatic cell count (SCC was within legal parameters, presenting negative correlation with milk production (r = -0.23 and lactose content (r = -0.39. However, the total bacterial count (TBC was above legal parameters. Education level seems to interfere in management and milk quality, because the less educated groups are, the less adequate are infrastructure, management, and product quality. Data show that there is a lower quality milk production where poor management techniques are adopted and owner education level affects milk quality.

    The region of South-Central Brazil includes the states of Sao Paulo, Rio de Janeiro, Guanabara and Minas Gerais. The most recent power study was made by Canambra Engineering Consultants Limited. This group reported that the public-grid electricity output for the area in 1962 was 2.16 GW (average generation), with an installed capacity of 3.41 GW and annual mean load factor of 63.4; an increase in power requirements for 1970 was forecast, corresponding to an average output of 5.37 GW and an installed capacity of 8.3 GW. This forecast was based on an annual growth rate of 11.9% in generation. ''The energy requirements have grown at an average annual rate of 10.9% since 1955; however, the present forecast is based on the assumption of power being available as required, and hence includes the suppressed demand resulting from existing restrictions in generating and distribution capacity''

    Studies of the genetic variation within populations of Coccidioides posadasii are scarce, especially for those recovered from South America. Understanding the distribution of genotypes among populations is important for epidemiological surveillance. This study evaluated the genetic diversity of 18 Brazilian strains of C. posadasii through the sequencing of the 18-28S region of nuclear rDNA, as well as through RAPD and M13-PCR fingerprinting techniques. The sequences obtained were compared to Coccidioides spp. previously deposited in GenBank. The MEGA5 program was used to perform phylogenetic analyses. Within the C. posadasii clade, a single cluster was observed, containing seven isolates from Ceará, which presented a single nucleotide polymorphism. These isolates were from the same geographical area. The strains of C. posadasii showed a lower rate of genetic diversity in the ITS1 and ITS2 regions. The results of M13 and RAPD-PCR fingerprinting indicated a similar electrophoretic profile. No differences between clinical and environmental isolates were detected. This was the first study assessing the genetic variability of a larger number of C. posadasii isolates from Brazil.

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

    2004-01-01

    The history of nutrition support in Brazil is parallel to its development in the world. Inspired by the publications of the surgical group headed by Professor Rhoads at the University of Pennsylvania, a group of Brazilian physicians pioneered the beginning of parenteral nutrition (PN) therapy. The Brazilian Society of Parenteral and Enteral Nutrition (SBNPE) was officially founded in 1975. Soon, scientific contributions started to appear, reflected by articles in the Journal of Parenteral and Enteral Nutrition and other journals and by books. In many states of Brazil, nutrition support services were created to carry out scientific and educational activities. The relationship with the American Society of Parenteral and Enteral Nutrition was fundamental in the development of clinical nutrition in Brazil because of the strong scientific exchange between the United States and Brazil. However, after the stimulating initial launching, momentum slowed because of the lack of medical awareness and inadequate reimbursement. In Brazil, the federal government is responsible for the majority of health care, but enteral nutrition was not reimbursed. In response to this situation, a study in 4000 hospitalized patients was undertaken in Brazil. It was reported that nearly half of them presented with malnutrition, and > 12% had severe malnutrition. These alarming results were decisive in persuading the Brazilian government to begin reimbursement for enteral nutrition. Today, Brazilian hospitals that assist public health system patients receive reimbursement for enteral nutrition. However, it is required to have an officially registered nutrition support team and a certified and approved facility for enteral feeding preparation. Considering that low nutrition prescription in Brazil could be the result of lack of nutrition education (not required in most medical schools), the SBNPE participated in the creation of 2 very effective, practical, and dynamic courses for the basic teaching

    Brazil nuts provide a rich natural source of selenium, yet no studies have investigated the bioavailability of selenium in humans. We investigated the efficacy of Brazil nuts in increasing selenium status in comparison with selenomethionine. A randomized controlled trial was conducted with 59 New Zealand adults. Participants consumed 2 Brazil nuts thought to provide approximately 100 mug Se, 100 mug Se as selenomethionine, or placebo daily for 12 wk. Actual intake from nuts averaged 53 mug Se/d (possible range: 20-84 mug Se). Plasma selenium and plasma and whole blood glutathione peroxidase (GPx) activities were measured at baseline and at 2, 4, 8, and 12 wk, and effects of treatments were compared. Plasma selenium increased by 64.2%, 61.0%, and 7.6%; plasma GPx by 8.3%, 3.4%, and -1.2%; and whole blood GPx by 13.2%, 5.3%, and 1.9% in the Brazil nut, selenomethionine, and placebo groups, respectively. Change over time at 12 wk in plasma selenium (P nut (P nut group than in the placebo (P = 0.002) and selenomethionine (P = 0.032) groups. Consumption of 2 Brazil nuts daily is as effective for increasing selenium status and enhancing GPx activity as 100 mug Se as selenomethionine. Inclusion of this high-selenium food in the diet could avoid the need for fortification or supplements to improve the selenium status of New Zealanders.

  15. Tax regulating carbon market in Brazil: barriers and perspectives

    Marques, Fernando; Magalhaes, Gerusa; Parente, Virginia

    2010-01-01

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

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

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

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

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

  20. Potential geographic distribution of hantavirus reservoirs in Brazil.

    Directory of Open Access Journals (Sweden)

    Stefan Vilges de Oliveira

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

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

  2. Miracle drug: Brazil approves never-tested cancer medicine.

    Kuchenbecker, Ricardo S; Mota, Daniel M

    2017-07-01

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

  1. Breastfeeding on prime-time in Brazil.

    Science.gov (United States)

    Castello Branco, H

    1990-01-01

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

  2. URBAN WATERSHED STUDIES IN SOUTHERN BRAZIL

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

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

  6. The epidemiology of laryngeal cancer in Brazil

    Directory of Open Access Journals (Sweden)

    Victor Wünsch

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

    The aim of this study was to investigate the association of Brazil's staple food, rice, beans and manioc, and the incidence of type 2 diabetes mellitus type 2 (T2DM) in adults assisted by a Brazilian Family Doctor Program (FDP). The baseline information was collected on visits to 13 units of the FDP from July 2006 to December 2007 (CAMELIA Study). The units were revisited by trained researchers between July and December 2011, who reviewed medical records of all participants of the baseline. Biochemical, anthropometrical and blood pressure measurements, new diagnoses, and medical prescriptions were collected. Individuals ages ≥20 y, who were non-diabetic at baseline were included (N = 409). Food consumption was estimated using a validated semi-quantitative food frequency questionnaire. Incident of diabetes was classified according to fasting serum glucose (≥126 mg/dL), individual's use of antidiabetic drugs, and/or diagnosis of diabetes described in the medical record. Individuals who were negative at baseline and also were negative for the above conditions were classified as non-diabetics. Individuals who developed T2DM (N = 30) reported higher consumption of red meat and beans and less consumption of cassava flour, independent of the interval between visits and other potential confounding variables. The cassava flour showed a protective effect (relative risk, 0.910; 95% confidence interval, 0.842-0.982). The consumption of cassava flour, a low-cost product, could be considered in diets for the prevention and control of diabetes. The hypothesis must be investigated in cohorts from different populations and tested in randomized controlled trials. Copyright © 2014 Elsevier Inc. All rights reserved.

  9. Brazil: sex and self-worth.

    Science.gov (United States)

    1991-09-01

    An AIDS education project in Rio de Janeiro, Brazil has enabled male sex workers to discuss safe sex, sexual preference, and self-worth. The project, known as Pegacao ("Cruising"), is designed to establish personal contact with the male prostitutes. The educators most of whom are openly homosexual, and some of whom are former sex workers, operate out of 4 outposts in the city. In one such outpost, a popular restaurant, the educators wait for male sex workers (Miches, as they are called) to come and talk. The Miches come from several reasons. Some come to talk about life, other about sexuality, and others want to help in contacting a doctor or a psychologist. Pegacao now has contact with some 400-600 male prostitutes aged 14-23. Since most of the male prostitutes are illiterate, the education is based on discussion, not on printed materials. The discussions focus primarily on sexuality and sexual practices. Many of the Miches, who often come from the poor families, say that they are involved in prostitution as a temporary way of earning money. Most deny being homosexual, and many say that they have girlfriends and are thinking about getting married. The educators, however, suspect that many Miches hide their sexual preferenced and use prostitution as a way to express their repressed homosexuality. While the Miches admit penetrating their clients (identifying it with the "male" role), few acknowledge being penetrated (the "female" or "gay" role). But the high rate of sexually acquired infections in the rectum suggest that the Miches are engaging in receptive, unprotected anal intercourse more often that they care to admit. In addition to teaching them about safe sex, the educators try to help Miches develop a positive attitude towards their sexuality and develop a sense of self-worth.

    Triatoma sordida has a widespread distribution in Argentina, Bolivia, Brazil, Paraguay, and Uruguay and is frequently found in peridomestic environments. We investigated size and shape variability of T. sordida wings across Brazil. Field-collected adults from twelve populations were studied. For each individual female, seven landmarks on the right wing were digitalized. Shape variables derived from Procrustes superimposition were used in Principal Component Analysis (PCA). Wing size and shape variations among populations was explored by means of ANOVA. Wing centroid size was significantly different among T. sordida populations; specimens from Bahia (East) were larger than those of Mato Grosso do Sul (West). PCA based on wing shape variables showed low wing shape variability. These results reinforce previous data showing low genetic variability among T. sordida populations from Brazil.

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

    Science.gov (United States)

    Kent, Michael; Wade, Peter

    2015-12-01

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

    2016-08-01

    Full Text Available Bovine brucellosis caused by Brucella abortus is present throughout Brazil, whose prevalence distribution shows variations among states and within the productive areas of the states, causing serious losses to cattle production and public health due to risk of transmission to humans. Therefore, since 2001, the National Program for the Control and Eradication of Brucellosis and Tuberculosis (PNCEBT is being implemented in all Federative Units of Brazil, based on the compulsory vaccination of bovine females, control of animal movement and certification of brucellosis-free herds. This review covers the current epidemiological situation of bovine brucellosis in Brazil, issues related to public health and economic importance, as well as Brazilian initiatives to control the disease.

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

    2015-01-01

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

    The concentrations of Se, Ba, Zn and Mn were determined in samples of Brazil nuts collected in two ways: a) in a production farm predominantly for export and, b) in various points of sale from different regions of Brazil. Instrumental neutron activation analysis was the analytical technique used in this study. Results indicate that the concentrations of Se and Ba varied greatly among the Brazil nut samples analyzed. This large variability may be related to the soil characteristics from which the nuts were produced. An inverse correlation was observed between the concentrations of Se and Ba. On the other hand, the concentrations of Zn and Mn did not show significant differences among these samples. (author)

  18. Thermopower generation investment in Brazil--economic conditions

    Moreira, Ajax; Rocha, Katia; David, Pedro

    2004-01-01

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

    Leticia Martins Lamarão

    Full Text Available Enterovirus 71 (EV-71 has been associated to cases of neurological disease in many countries including Brazil. This virus has now been reported from three of the five Brazilian regions. Our study relates the findings concerning to the first isolate of this virus in Northern region of Brazil. A 15-month old female patient, from the rural zone of the municipality of Santana do Araguaia in southern Pará state was admitted at the hospital with acute, flaccid, asymmetric and ascending motor deficiency, located in the right lower limb. Stools samples from this child were inoculated in RD cells and was isolated an EV-71. We plan to sequence our strain and compare it to other isolates in Brazil. Differences at the molecular level can explain why EV-71 strains circulating in other continents, such as Asia, appear to be more virulent.

    Full Text Available Scatellini was proposed by Wirth & Stone, 1956 and currently includes 242 described species in nine genera. The tribe has representatives in all biogeographic regions and about 70 species occur in the Neotropical Region. Prior to this study, only two species were recorded from Brazil: Scatella obscura and Limnellia itatiaia. In this paper, species of Scatellini from Brazil are reviewed with an emphasis on the fauna from southern Brazil, where six new species have been discovered and are described herein: Scatella praia, S. plaumanni, S. rara, Scatophila darrowae, S. dianneae, and S. prainha. To facilitate identification of the tribe and included genera and species, we have included diagnoses of these taxa and have also provided an annotated key to the Neotropical genera in Scatellini. We have also provided illustrations of structures of the male terminalia of all included species of the genus Scatophila.

  1. Anthropology of health in Brazil: a border discourse.

    Langdon, Esther Jean; Follér, Maj-Lis

    2012-01-01

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

    2017-03-01

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

    2013-01-01

    The present study investigates the arguments used by university students in order to explain social differences between social minorities and majorities. In Brazil, the issues investigated refer to White and Black people. In Spain, the reference is to native Spaniards and Moroccan immigrants. The participants were 144 Brazilians and 93 Spaniards, who answered a questionnaire composed of socio-demographic variables and one open question about the causes of social inequalities between Black and White people in Brazil and between autochthonous Spaniards and Moroccan Immigrants. A model is proposed to integrate the four discursive classes found using ALCESTE software. In Brazil, the strongest argument is based on the historical roots of the exploitation of Black people. In Spain, cultural differences are the main explanation for social inequalities.

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

    Breast cancer is the most common cancer in women worldwide and 70% of breast cancer deaths occur in women from low-income and middle-income countries. Latin America has about 115,000 new cases of disease every year, with about 50,000 arising in Brazil. We examined the present status of breast cancer in Brazil as an example of the health effects of geographical, ethnic, and socioeconomic diversities on delivery of care. Our goal was to identify deficiencies that could be responsible for disparities in survival from breast cancer. We searched the English and Portuguese published work and reviewed national databases and Brazilian publications. Although the availability of publications specific to Brazil is low in general, we identified several factors that could account for disparities: delays in diagnosis due to low cancer awareness and implementation of mammography screening, unknown quality of surgery, and restricted access to radiotherapy and modern systemic therapies.

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

    Full Text Available OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test and 41.2% (two tests, and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25. A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with < 8 years of education (1.74%, who self-reported as black (1.8% or mixed (1.2%, those who did not receive prenatal care (2.5%, and those attending public (1.37% or mixed (0.93% health care units. CONCLUSIONS The estimated prevalence of syphilis in pregnancy was similar to that reported in the last sentinel surveillance study conducted in 2006. There was an improvement in prenatal care and testing coverage rate, and the goals suggested by the World Health Organization were achieved in two regions

    In the developed world, grid-connected photovoltaics (PVs) are the fastest-growing segment of the energy market. From 1999 to 2009, this industry had a 42% compound annual growth-rate. From 2009 to 2013, it is expected to grow to 45%, and in 2013 the achievement of grid parity - when the cost of solar electricity becomes competitive with conventional retail (including taxes and charges) grid-supplied electricity - is expected in many places worldwide. Grid-connected PV is usually perceived as an energy technology for developed countries, whereas isolated, stand-alone PV is considered as more suited for applications in developing nations, where so many individuals still lack access to electricity. This rationale is based on the still high costs of PV when compared with conventional electricity. We make the case for grid-connected PV generation in Brazil, showing that with the declining costs of PV and the rising prices of conventional electricity, urban populations in Brazil will also enjoy grid parity in the present decade. We argue that governments in developing nations should act promptly and establish the mandates and necessary conditions for their energy industry to accumulate experience in grid-connected PV, and make the most of this benign technology in the near future. - Research highlights: {yields} With the declining costs of PV and the rising prices of conventional electricity, Brazil will soon enjoy grid parity. {yields} The availability of raw materials (Si and green electricity) make Brazil an ideal candidate to become an important player in the PV production scenario. {yields} A feed-in tariff program in Brazil should be limited in time and size. {yields} A feed-in tariff program in Brazil should be large enough to stimulate the local market, but it should at the same time be small enough in order not to impose a large financial burden to consumers.

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

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

  15. The climate change/energy efficiencies market in Brazil

    International Nuclear Information System (INIS)

    2000-03-01

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

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

    Full Text Available The aim of this study is to analyse the present discussion in Brazil about the new legislation for the oil reserves in the pre-salt layer in the light of the historical evolution of environmental and energy regulations in Brazil. Based on the principle of sustainable development, we attempt to show the compatibility between the new model and the aims and actions defined in national policies for energy and environment in the Federal Constitution of 1988. The study upholds the construction of a holistic, participative process for the elaboration of national policies, which necessarily contemplates an intergeneration perspective.

    Full Text Available For Marx & Engels, communism is not a project, but a real movement of which the presupposition is the development of capitalism. The Brazilian Communist Party (PCB, as far back as 1924, offered an original contribution to the analysis of Brazilian society. The meeting of positivism and communism in the late 1920´s is the most advanced expression of Brazil´s leftist political culture. In the following decades, most communist intellectuals were leading figures in the elaboration of the national-democratic program of Brazil´s social revolution.

    Full Text Available Clostridium perfringens type A has been incriminated as the etiologic agent in jejunal hemorrhage syndrome (JHS, which is a disease that affects dairy cattle. Although this microorganism is considered an important enteropathogen the pathogenesis of JHS is still not clear, and there have been no reports of its occurrence in Brazil so far. The aim of this study was to describe the occurrence of JHS by infection with a C. perfringens type A strain carrying the beta-2 toxin gene in a zebu cow in Brazil, for the first time.
