    This thesis presents a contribution to the subject of ore technological characterization integrated to orebody context, regarding sample, ore characteristics, ore types definition and distribution through the mineral occurrence, and ore reserves modeling using technological parameters. A professional experience in this specialization based a conceptual discussion of the matter, supported by a practical approach. The initial approach is the subject definition, and it`s importance for technological and economical feasibility studies, in all phases of mining research and development, as a tool for beneficiation alternatives definition. The multidisciplinary aspect of the knowledge involved for ore characterization is remarked, considering that is an interface segment to be conduced interactively with others. It is an applied mineralogy, that needs some geological and some ore dressing imputes. After the general considerations about importance and applicability, it follows a methodological approach of laboratory procedures and analytical techniques, as a result of practical experience acquired in the study of several ores. The main points discussed are related with criterion to organized laboratory preparation scheme and to select appropriated analytical techniques, without detailing them, for what some specialized bibliography is indicated. Finalizing the theoretical explanation, there is a concise description about computers resources for 3D orebody modeling, and integrated software applied for geology and mining. For illustration, it is exposed a complex ore case study: niobium mineralization associated with the alkaline-carbonatitic occurrence of Catalao I, located in Goias State, Brazil. Besides the explanation of laboratory procedures and methods applied, results treatment and interpretation are emphasized, under both characterization and economic point of view.

    Basaltic litotypes from the rock mass foundation of Canoas I Hydroelectric Power Plant were submitted to technological characterization tests, in order to verify their suitability as construction material. Physical and mechanical properties (density, porosity, water absorption, ultrasonic velocity, compressive and splitting tensile strength, among others) were determined, besides petrographic analyses. Weather ability tests were also performed, not only through wetting-drying cycles and by immersion in ethylene glycol but by outdoor exposure as well, using crushed and core drilled specimens. Detailed procedures for the weather ability test using core specimens from rotary drilling are given. It is analyzed the influence of a geological feature (fault zone, about 10 meters thick and 20 degrees dip), that occurs in the rock mass foundation, on the technological properties of these rocks. Basaltic litotypes selected as construction material are then pointed out. (author)

    Kaolinitic clays are vastly used in ceramic industry. Light coloration burned clays are very useful in the coatings production because of their aesthetic. In this work clay material from Vitoria da Conquista (south-west Bahia, Brazil) was characterized by various techniques. Differential Scanning Calorimetry (DSC) shows a kaolinite characteristic curve with an endothermic peak at 492 deg C, which corresponds to the kaolinite - metakaolinite transformation. Transformation alpha to beta quartz is characterized by a 573 deg C peak. The samples were also characterized by water absorption and x rays powder diffraction. The 1100 deg C burned samples were tested by rupture tension with acceptable results. (author)

    A methodology to stratify the ethanol plants operating in the State of Sao Paulo, Brazil, in homogeneous groups is presented. This group was obtained by multivariate stratification techniques considering factors as scale of production, agricultural productivity, industrial efficiency and effective industrial capacity utilization. This methodology differs from those adopted by the Fundacao Getulio Vargas and the Organizacao dos Plantadores de Cana-Orplana who consider only one variable- the scale of production. The advantage of this multivariate stratification is that the result clusters reflect more accurately the differences among the existing distilleries. 4 refs., 2 tabs.

    This work has as its main objective the geomechanical characterization on the future rocky mass foundation of the Tijuco Alto dam, sited at the Ribeira river, in the cities of Ribeirao, Sao Paulo state and Adrianopolis, Parana state, Brazil, owned by the Companhia Brasileira de Aluminio (Brazilian company of Aluminium). To reach that target, field studies were made to qualify the geotechnical parameters of the rocky mass, in the axis area open galleries. It was also used in situ deformability and stress test results performed in those galleries, that were reinterpreted for a better adaptation of the mass values. The knowledge of the mass inherent characteristics together with the laboratories test results, allowed for the geomechanical classification applications in several different gallery sectors. The geomechanical data obtained allowed through mathematical expressions, to reach the rocky mass values correlations of interest to the work (deformability and strength), that could be compared to the in situ test results. That analysis permitted, besides the classification critical system evaluation, the geomechanical characterization of the rocky mass, focusing its ability to the dam arch construction. (author)

    In Brazil, the first step of nuclear fuel cycle - the mining and milling of the uranium ore - is developed at the Uranium Mining and Milling Facilities of Pocos de Caldas, Minas Gerais state. The wastes management is a very important aspect of the process. The understanding of the geochemical processes that occur in the tailings dam is a key question to define a plan of action concerning the decommissioning strategy of the facility. The objective of the present work was to give some issues to help in the adoption of the remedial actions concerning the decommissioning of the facility. It focused on the characterization of the most important geochemical processes regulating the mobilization of radionuclides and heavy metals in the tailings dam. Two cores from the tailings dam (uncovered area) were collected. Seepage and drainage waters were sampled, the same being true for the tailings dam lake. Groundwater form an aquifer bellow the tailings dam and superficial waters from a river that receives the effluents of the dam (Soberbo River) were also sampled. Data from the mining company were used to calculate the inventory of radionuclides and heavy metals deposited in the waste dam.The obtained results showed that pyrite oxidation is the key process in the mobilization of radionuclides and heavy metals from the wastes. Pyrite oxidation is a process regulated by oxygen diffusion and water. In the studied scenario it could be shown that the process was limited to a one meter deep layer in the uncovered part of the waste dam. Because of this, Fe, Al, Mn, Zn, Th and {sup 238} U showed higher concentrations in the bottom layers of the cores in relation to the upper ones. {sup 226} Ra and {sup 210} Pb showed opposite patterns. The coprecipitation with Ca SO{sub 4} was the most relevant mechanism in both radionuclides immobilization in the wastes. Sulfate was the only chemical species that could be assigned as a contaminant in aquifer bellow the waste dam. As a conclusion, the

    Technological advances by newly industrialized countries (NICs) have become a central concern of the recent literature on the political economy of development. Striking a fatal blow to dependency thinking, in so far as it had diagnosed a structural barrier to technological development, these countries have absorbed foreign technology and have developed a very impressive domestic technological capacity. Moreover, their exports have evolved from a traditional reliance on raw materials and unprocessed goods to include increasingly sophisticated manufactured goods and technology itself. The capabilities, motivations, and structures behind nuclear exports must be examined in light of these secular trends. This paper reports on this exploratory analysis of the country's emergence as a nuclear supplier which focuses on six major areas: the balance of motivations and constraints underlying Brazil's nuclear export potential; areas of extant capabilities that would allow the country to play a significant role as a nuclear supplier; formal and informal structures beneath nuclear export policy; patterns of nuclear trade as reflected in past transactions; prospects for continuity and change; generalizability of findings to other emerging suppliers

    Air quality of indoor environments can be influenced by different particles suspended in the atmosphere (dust, pollen, bacteria, fungi, and virus) that could cause damage to documents and induce allergic reactions in people working with these documents. in this work, we identified until genera the microorganisms present in the environment of the central archive of Universidad Pedagogica y Tecnologica de Colombia; specifically those that could cause respiratory allergies to personnel of this area. For the environment samples, we used the open petri dish sedimentation method using potato dextrose agar, and measured temperature and relative humidity during each sampling. Also, a survey was taken of the workers to record respiratory symptoms that could arise from handling documents. Samples were taken from the nostrils of some of these workers. Fourteen genera among fungi, yeasts, and bacteria, and two non-identified categories were isolated from the environment. The predominant fungal genera were Mucor spp. and Penicillium spp. with 36.6% and 27.5% of the total of isolated colonies, respectively. Yeast, mainly Rhodotorula genera, and bacteria with prevalence coccus forms were isolated in smaller proportions. There was not statistically significant correlation among the average of colony forming units and the temperature and relative humidity in the environment. In addition, nostril samples yielded only normal Microbiota of the nose, indicating that suggestive respiratory symptoms workers presented are not directly influenced by the presence of fungal spores in the environment at the central archive.

    This document is the Final Report for the project Introduccion de Mejoras Tecnologicas en el SISCOM II, or Improvements in SISCOM II Technology. It consists of a brief description of the activities carried out during the project, and several Annexes that explain in a deeper way each result. SISCOM II is the main telemetry system currently in use in the Spanish underground coal mining, but it was developed ten years ago and needed a technological update, which was the objective of this project. The aims of the project were: To develop Hardware and Software for the Out stations currently used (maintenance developments) To design new hardware and software, easier to use in the current and new applications of SISCOM II Both objectives were met, although not in the way originally intended. The main results were: In the field of old Out stations update: A new set of boards for the old Out stations was developed Out station's firmware was updated for the new hardware In the field new hardware and software design: SISCOM II Supervision software was completely rewritten, and now runs under Windows 3.11/Windows 95 (Originally it ran under DOS) A new hardware configuration (the RELIA 2000), easier to assembly, install and reconfigured, together with its firmware, was developed Generally speaking the activities were carried out accordingly to the original schedule, with one exception, due to changes in the market of this type of Systems. Because of the changes, which happened by the end of the project's time span, the structure of the new hardware was somehow different to the original design, although its functionality and performance is similar or even better than those of the original one.

    In order to provide new insights on mineralogical aspects of geochemical mapping/natural processes related to the chlorite formation (e.g. crystallochemistry and mechanisms of formation of these materials, which has been applied in different studies of environmental profiles), we investigated chlorite samples associated to the Pb-Zn-Ag sulfide ore from Canoas 1 deposit (Vale do Ribeira, state of Parana, Brazil). By means of Moessbauer (MS) and infrared (IV) spectroscopy, we addressed some issues as those related to the chloritization processes, as well as how Zn would be incorporated into its crystalline structure. Results carried out by ME and IV spectroscopy clearly pointed out for a chlorite occurrence, which in fact incorporates Zn into its structure and also alters the structural patterns for this mineral. Moreover, ME data sets indicated the presence of Fe which is located only in octahedral sites, in trans-configuration, and the Zn emplacement by the chloritization process also occurs in the brucite layer.

    This work analyzes the geological-geotechnical-geophysical behavior, aiming to define the characteristics of a karstic-fissural aquifer in the mid-northern region of the State of Ceara, named as Itataia Phosphor-Uranium Deposit. This area is constituted of marbles and gneisses from Itataia Group, which are morphologically located at a higher point to the south and at a lower point to the north, related to Paleoproterozoic Era. Fracture system led to the implantation of two karstic marble phases, being the oldest from Cambrian Period and the most recent from Tertiary/Quaternary Period. Porosity is secondary to fractures, fissures and crushed zones which act as hydraulic channels for groundwater flow. Major geophysics defined conducting lines are controlled by normal fractures and faults in both N70 deg E and N80 deg W directions, and secondarily in both N10 deg E and N30 deg W directions, dipping 70 deg -85 deg into the northern quadrant of the main axes. Fault characteristics are typical of graben and horst patterns. Rocks in the area are distributed into three classes of geotechnical massif: healthy rock, moderately altered and fractured rock, and strongly altered and fractured rock. The latter occurs predominantly in the center of the area, from the soil surface to an average depth of 150 meters. Groundwater flow is characterized by fractures which enlarged by the karstic phenomenon dissolution, and then become closer as deeper they are. This flow may be slower or even discontinue in light of silty-argillaceous alteration material that fill the open fracture gaps. Water level is not lower than 5 m or higher than 90 m, averaging by 30 m ali over the area. The synoptic piezometry map shows a general south-north direction; however in the southwestern portion - the recharge zone - it takes the south direction, while in the southeastern portion it takes the southeast direction.

    Biodiesel is an ester resulting from the transesterification reaction of an alcohol and an oil obtained from biomass. The products of the transesterification are an ester and the glycerol. The biodiesel and the petroleum commercial diesel have similar properties, and they can be mixed and used in diesel motors. The use of biodiesel will allow a better exploration of the energetic potential of our cultures. The biodiesel has some advantages compared to others combustibles, such as adaptability to usual diesel motors and non-generation of NO{sub x} and SO{sub x} compounds. Many experiments with biodiesel have been made in Brazil since the 70's. This work made samples of biodiesel by transesterification batch reactions to many blends of soybean oil and residual fry oil, at room temperature, using mechanical mixture or magnetic agitation by a magnetic stirrer, using as catalysts sodium methoxide and potassium hydroxide. For each obtained sample tests to determine the Acidity Index (ABNT-MB-74), Saponification Index (ABNT-MB-75), Iodine Wijz Index (ABNT-MB- 77), thermal analysis by DTA and TG (TA Instruments SDT 2960, 30 to 800 deg C, 10 deg C/min at nitrogen atmosphere) and rheological test (Haake RS 150 Rheo Stress rheometer) were done.

    The excessive dependence of energy of the current societies, and the growing concern with the potentials associated climate change motivate the implementation of energy systems with base in resources of renewable energy. Climate change is the greatest environmental challenge the world is facing today. Rising global temperatures will bring changes in weather patterns, rising sea levels and increased frequency and intensity of extreme weather events. The effects will be felt here in Brazil; internationally there may be severe problems for people in regions that are particularly vulnerable. Brazil with experience in the bio fuels production can participate as a supplier of new technology for his production, at world level. This work, shows the recent evolution of the regulation for the bio fuels in Brazil, as well as their main ones routes technology, and it indicates the possible alternatives to guarantee the sustainability for the production and use.

    Brazil is a country of extensive agricultural land and great oil consumption and these factors favor biodiesel production in this country. In order for diesel/biodiesel mixtures to be effectively employed in diesel engines, a rigid quality control of these mixtures is needed. Biodiesel and mixtures must have their quality monitored with respect to oxidative resistance, thermal stability, fluidity and volatility, properties which can be modified by the adverse transport and stock conditions prior to consumption. Oxidation is the main degradation mechanism of products under transport and stock conditions, which can lead to significant economical losses. In this work sought the thermal degradation of neat biodiesel, synthesized in our laboratories was monitored. Thermal aging was conducted at 210 deg C for up to 1000 h. Virgin and thermally degraded samples were characterized by rheological measurements (in different shear conditions); FTIR; density and by color changes. We concluded that the soy biodiesel was successfully synthesized and that thermal exposure caused thermal-oxidative degradation of the biodiesel sample, significantly changing its properties as a function of thermal exposure times.

    Naphthenic acid corrosion was observed for the first time during the distillation process of some kind of crude oils in 1920. Recent reports about naphthenic acid corrosion have been found in China, India, Venezuela, Eastern Europe, Russia and the USA. In Brazil, heavy and acid crude oil processing is rising. Some brazilian crude oils have TAN around 3,0 mg KOH/g. The presence of relatively high levels of naphthenic acids in crude oils is a bane of petroleum refiners; and more recently, of producers as well, who have reported problems during production with calcium and sodium naphthenate . Essentially, these acids which are found to greater or lesser extent in virtually all crude oils are corrosive and tend to cause equipment failures, lead to high maintenance costs and may pose environmental disposal problems. In order to give these information to PETROBRAS, The Research and Development Center of PETROBRAS (CENPES) has been working in house and with brazilian universities developing analytical technicians to know better molecular structures and distribution of these acids compounds in crude oils. This work presents the actual methods and some results from these developments. (author)

  9. Datafile: Brazil

    International Nuclear Information System (INIS)

    There is as yet little to show for the enormous investment made by Brazil over the past 20 years in nuclear power and the fuel cycle. The only nuclear power plant (657MWe PWR) in operation has had a poor performance record and the two reactors (1309MWe PWRs) under construction are more than ten years behind the original schedule. Aspirations of building commercial fuel cycle facilities have proved extremely optimistic. In the latest reorganization of the industry, the construction and operation of nuclear power stations is entrusted to the national utility and the various civilian/military R and D efforts in the fuel cycle are being integrated under civilian supervision. This should lead to greater accountability and efficiency in the future. (author)

    This work describes the geometric and kinematic characteristics of the Major Gercino Shear Zone (MGSZ) in the Canelinha-Garcia area. This shear zone is one of the major lineaments that affect all southern Brazilian precambrian terrains. In Santa Catarina State, it separates, along its whole extension, the supracrustal rocks of the Brusque belt (northern part) from the Granitoid belt (southern). This zone is characterized by a regional NE trend and a dextral sense of movement where ductile-brittle structures predominate. The MGSZ is composed of two mylonitic belts separated by granitoid rocks probably associated to the development of the shear zone. Both shear zones show cataclastic to ultra mylonitic rocks, but mylonites and protomylonites conditions at high strain rate. The calc-alkaline granitoids present in the area can be grouped in two granitoid associations with meta to peraluminous affinities. The Rolador Granitoid Association is characterized by grayish porphyritic biotite-monzogranites and the Fernandes Granitoid Association by coarsed-grained to porphyritic pinkish amphibole-syenogranites. The U-Pb and Rb-Sr ages range from 670 to 590 Ma with the Sr{sup 87} / Sr{sup 86} initial ratios suggesting a crustal contribution in the generation of these rocks. The importance of the pure shear component is also emphasized by the results of the Fry method. Many z axes of the strain ellipses are at high angle to the shear foliation. Symmetric porphyroclasts also corroborate this hypothesis. The micaceous minerals formed during the shear development indicate K-Ar ages around 555 {+-} 15 Ma. Brittle reactivations of the shear zone have been placed by K-Ar in fine-fraction materials at Triassic time (215 {+-} 15 Ma.) 220 refs., 107 figs., 18 tabs., 4 maps

    The studied area is located in the southwestern portion of Minas Gerais State, encompassing the counties of Alfenas, Areado, Machado, Poco Fundo, Campestre, Serrania, Monte Belo, Bandeira do Sul, Botelhos and Cabo Verde. This region is dominated by strongly weathered pre-cambrian rocks in association with colluvial-alluvial sediments. The present work consisted in a comparison among the mineralogical (X-Ray Diffraction), textural (Laser Granulometry), chemical (X-Ray Fluorescence) and technological (mechanical resistance, water absorption, etc, made in specimen tests) properties of the clays collected on potteries located in these counties. The mineralogical and chemical analysis displayed the kaolinitic nature of the clays from this region, showing also small amount of interlayered clays and large amount of quartz. The best results of physical analysis were obtained for clays from the counties of Cabo Verde and Monte Belo due to the presence of lower values of SiO{sub 2} (quartz) associated with a finer particle size distribution.

    This paper presents a retrospective of some of PETROBRAS' main technological advances that contributed for Brazil to reach petroleum production self-sufficiency. The impact of the corporate strategy to invest in training and qualifying human resources in the development of critical technologies for the Company's business is discussed. From the mid-seventies, there has been a significant increase in the effort directed to research and development (R and D) in the Exploration and Production (E and P) segment. Motivated by challenges imposed by ever increasing water depths (WD) and the early production of discovered fields, technological developments accelerated. A few of the topics discussed herein include the competition between wet subsea systems and atmospheric systems, the first floating production units based on semi-submersible drilling platforms and on adapted tankers, the development of wellhead systems, risers and production lines. Beginning in the mid-eighties, PETROBRAS successively broke world records in terms of water depth with its wells and production and off loading facilities. In order to support this leadership, new technologies were developed and adapted, in partnership with vendors and scientific and technological institutions, in the country and abroad. This paper discusses the technologies developed for maintaining the production of mature fields, increasing the production capacity and managing the integrity of installed units, managing great volumes of produced water as a function of mechanisms adopted for the maintenance of reservoir pressure and managing production projects. In conclusion, the main solutions currently in development are described. (author)

    The refining processes, the catalytic hydrocracking is the future of diesel oil in Brazil and the first units are already scheduled to be inaugurated. Among the catalysts used in this process, silicoaluminophosphates (SAPO's) have considerable potential for use as they have been effective in the isomerization of n-alkanes, the isomerization of olefins and alkylation of aromatics. Because of this, the objective is to develop catalysts that will be used in hydrocracking reactions. The media like SAPO-5 were synthesized with different ratios silicon/aluminum, which is used as a catalytic support and have the function of crack organic molecules, since it has acidic character. The materials were characterized by techniques: X-ray diffraction, chemical analysis and textural by BET. After summarizing the media found that they had agreements with the crystalline phases presented in the literature.(author)

    Brazil is the greatest world producer of beryl (3 Be O.Al{sub 2}O{sub 3}.6SiO{sub 2}) and has recently begun to produce beryllium compounds by means of a pilot plant constructed at Governador Valadares city (Minas Gerais - Brazil). The aim of this work was the determination of trace level impurities and macro constituents in the tenth % range to support analytical control process of plant production and characterization of beryllium compounds. The impurities separations and purification process was developed by two steps procedure. The first one using EDTA complexation has separated and reduced some impurities to less than 1 {mu}g/ml level. In the second one it was used a chelating resin (Chelex 100) and the separation efficiency was about 75 to 97 % related with the element tested. High pure berylium oxide standard was obtained from purification of Be(OH)2. The R X fluorescence presented only traces of Cu and Si < 1 % Fe and Mn, Zn, Ca, Al, Na and S were completely removed. The beryllium content was determined by direct atomic emission spectroscopy in argon plasma (Dcp) and compared with classic gravimetric method as Be O. The results were in agreement (49,2+/-0,2 % and 48,3+/-0,1 % respectively) between 95 % of confidence. A low temperature gravimetric method for beryllium determination was also studied using Oxine with microwave furnace. A total of 24 elements including macro and trace level were determined by Dcp and/or spectrophotometric methods. The Be/B separation was studied using anionic resin in poly alcohols medium. A more detailed study of equilibrium conditions is necessary. This work was realized at Laboratorio de Analise Mineral (LAM) of Comissao Nacional de Energia Nuclear - Rio de Janeiro (CNEN). (author)

    The problems and the damages caused by the corrosion in the production and refining of the oil are enormous. In the process of refining it is present among other substances, naphtenic gas where the character of the corrosive attack is significantly aggressive. The deterioration provoked by hydrogen is the most harmful deterioration in an oil refinery. There are several publications that certify eht excellent protection conferred to the steel in industrial atmosphere given by aluminum coating. This covering represents a pure ideal compromise between the passive protection and the active protection. Moreover, the presence of a metal to metal layer (Fe/Al) in the zone between aluminum and steel, obtained by additional thermal heat treatment, represents an additional protective barrier, in particular against the diffusion of hydrogen in the steel in environments that contains naphtenic gas ou sulfide acid. In industrial scale, tubes are manufactured through the process of alonizing and it is already used in the Presidente Getulio Vargas Refinery - REPAR, PR, Brazil. The process require a heat treatment to allow the diffusion of aluminum in the tube in order to form the Fe/Al intermetallic, which presents recognized resistance to the sulfurous corrosive environment in the oil refining. This was the motivation for the characterization of these alonized steel in order to determine what types of intermetallic are formed. Test samples have been prepared and optic and electronic microscopy examinations was varied out. The studied alonized surface showed enhanced hardness and additionally, it was observed that the aluminum diffusion permits the formation of a different types of Fe/Al. It was also found the presence of aluminum without the formation of intermetallic. (author)

    The certified reference materials (CRMs) play an important role in obtaining measurement results traceable to the International System of Units, through an unbroken chain of comparisons. Thus, the demand for new certified reference materials (CRMs) increases every day in all areas of knowledge. The availability of reference materials, mainly in Brazil is still incipient, given that the demand far exceeds the available variety of these materials. The amount of certified reference materials available in the country is insufficient to meet the need of the scientific community and demands for development of new methodologies. Among the many areas in need of reference materials, we highlight the importance for the food trade balance for these products within the country. The certification of food products, intended both for export and for domestic consumption, requires analysis methods that provide precise and accurate results to ensure product quality. This paper describes the preparation and certification of a reference material in the fish matrix in mercury and methylmercury. The study brings together since the stage of material selection, preparation, development of homogeneity and stability studies and characterization. The certification was performed by means of measurements using two analytical techniques, flow injection analysis - cold vapor atomic absorption spectrometry (FIA-CV-AAS) and isotope dilution applied to mass spectrometry (IDMS), which is a primary method. In this work the standards of the ISO 30 (ABNT 30-34) and ISO Guide 35 was used as the basis for the preparation and characterization of the material. For the calculation of uncertainties was used the GUM and Eurachem guide. As a result, was produced and certified a lot of material in relation to the concentration of mercury (Hg = 0.271 {+-} 0.057 mg g{sup -1}) and methylmercury (MeHg = 0.245 {+-} 0.038 mg g{sup -1}), and informational values of lead and arsenic.

In support of the country's nuclear power program, Brazil has developed the most active uranium industry in South America. Brazil has one operating reactor (Angra 1, a 626-MWe PWR), and two under construction. The country's economic challenges have slowed the progress of its nuclear program. At present, the Pocos de Caldas district is the only active uranium production. In 1990, the Cercado open-pit mine produced approximately 45 metric tons (MT) U3O8 (100 thousand pounds). Brazil's state-owned uranium production and processing company, Uranio do Brasil, announced it has decided to begin shifting its production from the high-cost and nearly depleted deposits at Pocos de Caldas, to lower-cost reserves at Lagoa Real. Production at Lagoa Real is schedules to begin by 1993. In addition to these two districts, Brazil has many other known uranium deposits, and as a whole, it is estimated that Brazil has over 275,000 MT U3O8 (600 million pounds U3O8) in reserves

    Over 1700 liver transplantations (LTs) are performed annually in Brazil. In absolute terms, the country performs more LT surgeries than anywhere else in Latin America and is third worldwide. However, due to its increasing population and inadequate donor organ supply, the country averages 5-10 LTs per million population, far lower than required. There is a marked heterogeneity in organ donation and LT activity throughout the country. Access to LT in the underprivileged North, Midwest, and Northeast regions of Brazil is scarce. Major challenges for the future of LT in Brazil will be to increase organ donation and access to LT. The reduction of those geographical disparities in donation, organ procurement, and LT due to political and financial constraints is of utmost importance.

    Castilho, Marcelo [National Petroleum Agency of Brasil (Brazil)

    2011-07-01

    Brazil is one of the world's largest economies and the country also has significant heavy oil reserves. This report from the National Petroleum Agency of Brazil aims at presenting the situation of the oil and gas sector in Brazil in terms of resources, production, regulatory framework and opportunities for the future. Brazil has numerous sedimentary basins at its disposal, most of them being prospected by both national and foreign companies from all over the world. Brazil has over 14 billion barrels of proven reserves, its production is 2,1 MMBbl/d and heavy oil represents almost 40% of that production. The National Petroleum Agency of Brazil is responsible for the implementation of oil sector policy with the aims of maintaining self-sufficiency, implementing good practices in terms of health and safety, and increasing local content. This paper pointed out that Brazil has an important opportunity to enhance its energy sector through the development of heavy oil.

  13. Brazil: anchoring the region

    International Nuclear Information System (INIS)

    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

    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 Campos Basin is known as one of the most challenging deep water basins in the world. Currently there are thirty-seven platforms, more than a thousand oil wells, and about 4200 kilometers of submarine pipelines, having produced more than 1,2 billion barrels of oil per year and 15,7 million cubic meters of gas per day. The Campos Basin is responsible for more than 80% of Brazil's national production. Brazil intends to produce 2,2 million barrels of oil per day by 2007, when it will reach self-sufficiency. Therefore, the continued development of the offshore basins, such as Campos, Santos and Espirito Santo will be critical to meet this goal. In this context, the technological evolution of the vessels that render stimulation services is of fundamental importance to improve job quality, reduce time, protect with the environment, enable efficient communication, and ensure operational viability of new techniques. This paper reports on the history of this vessels, describing and illustrating new and state-of-the-art technology, historical cases of pioneering operations, data transmission in real time and the benefits for offshore operators with a global vision.

    Full Text Available Starting out from the document drawn up by OECD on the Italian “Digital School” project for the introduction of technological innovation in schools, the author discusses the criteria to which innovation policies based on the principles of sustainability and maximum pedagogical impact should be subject, in an Evidence Based Education perspective. Historically we tend to overestimate the positive effects of technology on learning, while research has already highlighted their limitations, which are restricted to specific areas, at the same time pointing to the risks related to consequent cognitive overload. Suggestions for decision makers are made, underlining the need to recover the educational relationship with easy technologies, take into account the cognitive balance between reading paper and digital reading and finalize well the use of technology for achieving specific objectives.

    2014-01-01

    Full Text Available The number of schools of pharmacy has been increasing each year in Brazil. From 2002 to 2013 over 300 new schools were opened in Brazil with a final number of 415 schools of pharmacy in operation around the country. Of these schools, only 28 schools offer a course in radiopharmacy (7.77%. However, the demand for such trained professionals has grown exponentially in Brazil, especially following amendment 49 (February 2006 that broke the monopoly on the production, distribution, and marketing of short half-life radiopharmaceuticals, and the recent constitutional amendment project 517/2010, which was approved in the last instance and is waiting for final approval by the President. Thus, in this scenario, there are a total of 417 radiopharmacy services across the country waiting for qualified professionals to fill posts. However, while there are insufficient trained professionals, radiopharmacy services under the aegis of Agencia Nacional de Vigilancia Sanitaria - Brazilian Health Surveillance Agency allow biomedical scientists and biologists to perform specialized functions as developed in radiopharmacy services without the presence of radiopharmacists.

    This paper describes the practice of sociodrama, a method created by J. L. Moreno in the 1930s, and the Brazilian contemporary socio-psychodrama. In 1970, after the Fifth International Congress of Psychodrama was held in Brazil, group psychotherapy began to flourish both in private practice and hospital clinical settings. Twenty years later, the Brazilian health care system added group work as a reimbursable mental health procedure to improve social health policies. In this context, socio-psychodrama became a key resource for social health promotion within groups. Some specific conceptual contributions by Brazilians on sociodrama are also noteworthy.

    This study evaluates the implications of different geopolitics scenarios over the productive and technological strategies for exploiting national oil resources. Initially, it discusses the international oil market fundamentals, focusing the dynamics of the light-heavy prices differential. Then, it analysis the effects three possible scenarios over such market fundamentals: Strong OPEC due to 'reinforcement of the price band mechanism discipline'; Weak OPEC due to 'market contestation' (productive empowerment of non-OPEC countries or quitting of OPEC member-countries interested in getting more productive autonomy - such as Algeria, Nigeria and, eventually, Iraq); and, Weak OPEC due to 'strategies to reduce geopolitics vulnerability' (minimization of supply disruption risks). Afterwards, it evaluates the impacts of those scenarios over the productive and technological strategies for exploiting national oil resources. Finally, it concludes that the scenarios of Strong OPEC and Weak OPEC due to 'strategies to reduce geopolitics vulnerability' are the most favorable for the exploitation of national oil resources, whilst the scenario Weak OPEC due to 'market contestation' would challenge the oil companies operating in the country to generate productive and technology strategies which strongly promotes E and P cost reduction in Brazil in order to maintain the competitiveness of the national oil.

  8. Fuelwood utilization in Brazil

    International Nuclear Information System (INIS)

    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)

  9. Waste management in Brazil

    International Nuclear Information System (INIS)

    The waste management policies set up in developed countries have in general been used by other countries with less experience in the nuclear field as the basis for developing waste disposal rules or guidelines according to their particular political, social and economic conditions. The waste management question became a main concern in Brazil during the licensing period of the Angra I nuclear power plant and the other fuel cycle facilities envisaged under the Agreement between Brazil and the Federal Republic of Germany. Before the Angra I licensing period, all final waste products arising from nuclear activities were released into the environment because their radioactive levels were below the standard limits. The Research, Development and Demonstration (RDD) Project initiated by the National Nuclear Energy Commission has the purpose to provide information that may contribute to the formulation of recommendations for a waste disposal policy, as well as to demonstrate the feasibility of the Brazilian waste disposal concept. The paper briefly describes the waste management policy in some countries, their contributions to the studies carried out in the RDD Project, and the recommendations and mechanisms for implementing the waste management proposal, and presents general information concerning the Brazilian repository concept.

    The application of montmorillonite nano composites has been improved in order to obtain dispersed phase with particles of nano metric dimensions. To obtain these nanoparticles, the clays must pass an effective purification process for removing unwanted materials, which would undermine the processes of intercalation and exfoliation of montmorillonite in a polymer matrix. This study intention to characterize and purify a montmorillonite clay from deposit recently discovered in the city of Parelhas in Rio Grande do Norte, through the separation of coarser materials by decantation followed by a chemical attack that promoted oxidation in samples where it was realized reduction of impurities such as organic matter and other substances that would hinder the achievement of nanoparticles. Under these conditions, the clay is suitable for the work as dispersed phase in a polymer matrix nano composite. The results were demonstrated by analysis of scanning electron microscopy (SEM), chemical analysis, BET and X-ray diffraction (XRD). (author)

    The aim of this work is analyze the vertical seismic resolution of the turbidity reservoir of Namorado Field. In this work the seismic modeling was accomplished using the convolution method. The wavelet used was the Ricker type with dominant frequency of 20 hz, 35 hz and 50 hz. The results show that wavelet with frequencies of 35 hz and 50 hz have better seismic resolution than wavelets of 20 hz, however all frequencies delimit top and base of the reservoir. From the acoustic impedance model, obtained from the synthetic seismogram, was possible, knowing the correlation of this variable with reservoir rocks, determine the distribution of reservoir facies. For that was used the geostatistical analysis that still enabled the studies regarding to the scenarios analysis by means of the application of stochastic methods. (author)

    Formation water is the water present in reservoir rock pores, produced together with petroleum. Usually it is hyper saline with concentrations that can be higher than 250 g/l of dissolved solids. The concentration of the dissolved elements and the isotopic composition of the water and of some of the dissolved elements can be excellent tracers to study the dynamic of underground fluid flux, the mixing of distinct sources and the origin of salinization of these waters. This work reports the isotopic composition ({delta}{sup 2}H , {delta}{sup 18}O) and electrical conductivity (EC) of formation waters from 10 wells of a petroleum field of the Reconcavo Basin, looking for their evolution, interaction with the minerals and rocks and reservoir interconnection. The samples have electric conductivity ranging from 84 to 137 mS/cm, with conductivity increasing with depth of production zone. It is observed an enrichment of deuterium and oxygen-18 with the depth of production zone, probably due to water-rock interactions that were probably increased by higher temperatures of the deeper levels and longer residence times. The samples from the production zone between 1450 to 1520 m, drained by 7 of the 10 wells sampled, show a small range in isotopic composition and in electric conductivity, indicating homogeneity in this level of the reservoir. In the shallow level of 450 m the values of {delta}{sup 2}H , {delta}{sup 18}O and EC are lower, with isotopic composition similar to the oceanic water, possibly representing the original water that entered the reservoir during the sedimentation of the basin.

    The large volume of waste generated by the industry of wood processing and agriculture is a problem existing in almost all regions of Brazil. Several environmental problems occur as contamination of soil and groundwater due to the accumulation and improper disposal of residues from forestry and agriculture industries. Brazil has agricultural and economic conditions to develop and take advantage of technologies to use wood and other biomass for energy purposes, for being privileged in terms of territorial extension, sunlight and water, essential factors for biomass production on a large scale. The wood chips and coffee husks are low cost residues, renewable and sometimes under utilized, they are environmentally friendly and potentially capable of generating heat, steam and electric power, thus they can contribute as an alternative fuel for generation of energy. In this context, this study aims to characterize and compare residues from the production of coffee and furniture industry. The biomasses were characterized and analyzed for density, heating value, proximate analysis (volatiles, ash and fixed carbon) and elemental composition. Results indicates large energy potential for coffee husks, with HHV equals to 18,6 MJ/Kg slightly higher than the HHV of the eucalyptus chip (17,3 MJ/Kg). (author)

    Brazilian space activities develop around three main programs, namely, the China-Brazil Earth Resources Satellite (CBERS) , the Applications Satellite program, comprising the Multi-Mission Platform and associated remote sensing payloads (radar and optical), and the Scientific Satellites program. Increasing national industry participation and acquiring new technology are strategic goals established for all programs. CBERS program is the result of successful long term cooperation between China and Brazil for the development of remote sensing satellites. Initially comprising two satellites, launched in 1999 and 2003, and now extended to four, this cooperation fulfills the needs of both countries in earth imagery. CBERS satellites are designed for global coverage and include cameras for high spatial resolution and wide field of view, in the visible, near infrared spectrum, an infrared multi-spectral scanner, and a Transponder for the Brazilian Environmental Data Collection System to gather data on the environment. They are unique systems due to the use of onboard cameras which combine features that are specially designed to resolve the broad range of space and time scales involved in our ecosystem. Applications satellites, mainly devoted to optical and radar remote sensing, are being developed in the frame of international cooperation agreements, and will be based on the use of a recurrent Multi-Mission Platform (MMP), currently under development. The MMP will be 3-axes stabilized and will have a fine pointing capability, in several pointing modes, such as Earth, Inertial or Sun pointing. Missions will be focused on natural resources observation and monitoring.. The Program for Scientific Satellites is based on low-cost micro-satellites and aims at providing frequent flight opportunities for scientific research from space, whilst serving as a technological development platform, involving Research Institutes, Universities and National Industry.

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.

    The Brazilian population has heterogeneous ethnic origins and is unevenly distributed in a country of continental dimensions. In addition to the Portuguese colonists until the end of the World War II Brazil received almost 5 million immigrants who settled mainly in the south and southeast. This features of the Brazilian population have two important consequences for the inherited diseases that are associated with an ethnic background: their frequencies are different in various regions of the country reflecting a variety of ethnic origins and variable degrees of admixtures. There was no report about the molecular basis of hypercholesterolemia in Brazil until our report in 1996 that the Lebanese allele is the most common cause of the disease in our country: 10 out of the 30 families were of Arab origin, and the Lebanese allele was detected in 9 of the 10 unrelated families of Arab origin. In addition, the abnormal gene is associated with the same haplotype at the LDL-R locus in all but one family, suggesting single origin for this mutation. Recently we described seven mutations in exons 4, 7, 12 and 14 and a new mutation in exon 15. In another region of our state, eight mutation already described and seven new mutations were described and interesting no common mutations were find. We can conclude that the complex history and structure of the Brazilian population, which was formed by the contribution of a large number of ethnic components that are in a state of increasing miscegenation, is reflected in the frequency and regional distribution of the more common hereditary diseases.

    The Crotalus durissus terrificus venom has been so far described as being of low complexity, with four major components described: convulxin, gyroxin, crotoxin and crotamine. In recent studies, other components of this venom were characterized as, for example, an analgesic factor. In 1980, Vital Brazil predicted the existence of a toxin which could be involved in platelet aggregation, and named it delta toxin. However, this toxin has never been isolated or characterized. The aim of the present work was to purify and characterize this toxin. After FPLC size exclusion chromatography followed by reverse phase HPLC, an homogeneous fraction was obtained, with a molecular weight of 14,074.92 Da. When analyzed by SOS-PAGE, this toxin presented an anomalous behavior, with a molecular weight of 14 kDa, while in 2D gels, spots around 40 kDa and with an isoelectrical point between 4 and 5 were observed suggesting isoforms with glicosilation microheterogeneity. After trypsin digestion, the fragments were submitted to the swissprot databank showing high homology (43% coverage, 15 matching peptides) with trocarin, a prothrombin activator from Tropidechis carinatus. These data were further confirmed by aminoacid analysis. The toxin was tested for its ability to activate factor II and X using synthetic substrates. Our data indicate a direct activation of factor X. The same toxin also behaved as a potent direct platelet aggregation activator on washed platelets. Assays with specific inhibitors indicate that neither metalloproteinase, nor serinoproteinase or t lectin domains are involved in the aggregating activity, since EDTA, benzamidin and D-galactose did not inhibit the toxin. In the present work, we were able to identify, purify and characterize a new toxin from the brazilian rattlesnake. It behaved as predicted by Vital-Brazil and displayed direct factor X activating properties, also inducing platelet aggregation, even at low concentrations. Our data also indicate that it is

    Persons who are infected with human immunodeficiency virus (HIV) or who suffer from acquired immunodeficiency syndrome (AIDS) often have their civil rights violated in Brazil. To remedy this, the Candido Mendes College in Rio de Janeiro introduced a voluntary course, "AIDS - Legal Approaches", into its law curriculum. Incentive was provided by the college's Model Law Office (MLO), where students learn to defend the rights of people in need. Class size is about 25; law professors use recent magazine and newspaper articles, and documentation on lawsuits concerning persons with HIV to teach the class. Course topics include relevant civil law (suits against blood banks), contract law (suits against private health insurance companies which refuse to cover treatment expenses related to HIV or AIDS), family law, inheritance law, labor law (unjust dismissal of persons with HIV), criminal law (intentional transmission of AIDS), violations of basic human rights, and comparative jurisprudence and constitutional law (a comparison of Brazilian law in this area to the laws of other countries). Students, during their field practice periods at the MLO, provide legal assistance to persons with HIV. Approximately 150 cases have been handled, often with positive outcomes, to date. Clients hear about the program via television, radio, and newspapers. Materials and information about lawsuits handled by the MLO are available to other colleges and universities with the hope of stimulating the formation of similar programs elsewhere. PMID:12288109

  7. Ethanol fuels in Brazil

    International Nuclear Information System (INIS)

    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

  8. Argentina and Brazil

    International Nuclear Information System (INIS)

    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

    This article is an excerpted summary of a speech on female police and domestic violence. The speech was given by a woman affiliated with the Association of Women Workers at an Oxfam workshop in northern Brazil. This organization successfully lobbied for female police, which resulted in more reports of domestic violence, especially rape. The organization is active in 13 counties. Female police are trained and usually given respect by police chiefs. In one city, in 1997, the appointment of female police resulted in registered reports of 387 cases of violence and hospital reports of 503 cases, of which 14% were child rape. During January-April 1998, there were 126 registered cases and 168 hospital cases. Policewomen formed a partnership over the past 2 years with the Human Rights Group and other popular political groups to train female police about laws. The compulsory course focused on four areas: legal concepts, penalties, and procedures on registration of complaints; the Brazilian Penal Code; civil law; and world judicial bureaucracies. Training includes a 1 month internship with the program's lawyer. Over 20 women have completed the course to date. Training in some cases resulted in greater expertise among the female police than their Police Chiefs. Female police have experienced harassment by local authorities. PMID:12295035

    The use of certified reference materials in chemical analysis is an important requirement in quality assurance systems, as it allows the validation of analytical methods and the realization of the metrological traceability of results. Then, it is possible to obtain valid and comparable results not only in space, but also in time. In this study, all the steps for the preparation of a national mussel reference material were attained, from the collection of the bulk material to processing steps such as freeze-drying, grinding, bottling and sterilization. Internationally accepted principles were applied for the homogeneity and stability assessment of the material, using instrumental neutron activation analysis and atomic absorption spectrometry as analytical techniques. By means of a collaborative program with participation of Brazilian and foreign laboratories, the chemical characterization of the material was performed. Element content in the mass percentage to mg kg{sup -1} range was determined for 47 elements and some radionuclides, naturally present in the material. With the application of suitable statistical treatment to the data, it was considered that the content of 11 of those elements may be certified: As, Ca, Cl, Co, K, Mg, Mn, Na, Se, Th and Zn. This study may be considered an important step in the national metrological development, as it shows that the production and characterization of biological reference materials, mussel in particular, is feasible in Brazil, as a tool for quality assurance of environmental and nutritional studies performed in the country.

    Zika virus (ZIKV) infection is spreading rapidly within the Americas after originating from an outbreak in Brazil. We describe the current ZIKV infection epidemic in Brazil and the neurological symptoms arising. First cases of an acute exanthematic disease were reported in Brazil's Northeast region at the end of 2014. In March 2015, autochthonous ZIKV was determined to be the causative agent of the exanthematic disease. As cases of neurological syndromes in regions where ZIKV, dengue and/or Chikungunya viruses co-circulate were reported, ZIKV was also identified in the cerebrospinal fluid of patients with acute neurological syndromes and previous exanthematic disease. By the end of September 2015, an increasing number of infants with small head circumference or microcephaly were noted in Brazil's Northeast which was estimated to be 29 cases between August and October. ZIKV was identified in blood and tissue samples of a newborn and in mothers who had given birth to infants with microcephaly and ophthalmological anomalies. In 2015, there were an estimated 440,000 - 1,300,000 Zika cases in Brazil. There have been 4,783 suspected cases of microcephaly, most of them in the Northeast of Brazil associated with 76 deaths. The Ministry of Health is intensifying control measures against the mosquito Aedes aegypti and implemented intensive surveillance actions. Further studies are needed to confirm the suspected association between ZIKV infection and microcephaly; to identify antiviral, immunotherapy, or prophylactic vaccine; to introduce diagnostic ELISA testing. Clinical and epidemiological studies must be performed to describe viral dynamics and expansion of the outbreak. PMID:26927450

    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.

  17. Mutation breeding in Brazil

    International Nuclear Information System (INIS)

    How mutation induction is used for plant breeding in Brazil is reported. For upland rice, the combined treatment with gamma-ray and mutagens (ethylene imine or ethylmethane sulfonate) has been used on the variety, Dourado Precoce, and some mutants with shortculm length and/or earliness without altering the productivity have been obtained. A project on the quantitative and qualitative protein improvement in upland rice was also started in 1979. In corn, the effect of gamma-irradiation on heterosis has been analyzed, and it was found that the single hybrids from two parental lines derived from irradiated seeds had increased ear productivity. For beans (Phaseolus yulgaris), gamma-irradiation and chemical mutagens have been used to induce the mutants with different seed color, disease resistance to golden mosaic virus and Xanthomonas phaseoli, earliness, high productivity and high protein content. Some mutants with partly improved characters have been obtained in these experiments. Two varieties of wheat tolerant to aluminum toxicity have been obtained, but the one showed high lodging due to its unfavorable plant height, and the other was highly susceptible to culm rust. Therefore, irradiation experiments have been started to improve these characters. The projects involving the use of gamma-irradiation have been tested to obtain the mutant lines insensitive to photoperiod and resistant to bud-blight in soybean, the mutant lines resistant to mosaic virus in papaya, the photoperiod-insensitive mutants in sorghum, the mosaic virus resistant and non-flowering mutants in sugar cane, and the Fusarium and nematode-resistant mutants in black pepper.

    The Health in Prostitution Project was launched in 1991 in Rio de Janeiro, Brazil. The project offers a multi-year training program of health education designed to both fight the stigmatization of and violence against commercial sex workers and enhance their self-esteem, self-determination, and access to civil rights. The project therefore promotes individual awareness while influencing public opinion and policies. At first, health agents were recruited among women and transvestites who work in street-based sex work. The program was then gradually expanded to include young male sex workers and other locations, such as private parlors, saunas, and escort services. People of all sexes and sexual orientation now comprise the health agent group. The program has a paid staff of five women, three young men, and three transvestites, and approximately 70 sex workers are trained annually. Basic training includes topics such as human sexuality, personal risk assessment, HIV/STD infection, negotiation of safer sex, and STD referral services. Year two training emphasizes reproductive and women's health issues, while year three courses prioritize street work methodologies. Theatrical performances, speaking English as a second language, and performing Bach flower therapy for clients take place during the fourth year. Program trainers include medical specialists, nurses, psychologists, health educators, lawyers, and university students. At least half of the 350 health agents trained thus far are estimated to be currently engaged in paid or voluntary prevention work. Two surveys with female sex workers in 1991 and 1993 found that reported regular condom use increased from 57% to 73%; the health agents are having an effect. The program is constantly evaluated and revised. PMID:12346918

    In many countries the rights of patients and consumers of health services are gaining ground and becoming law. As elsewhere, consumers in Brazil are becoming increasingly knowledgeable and demanding respect for their rights. Yet many Brazilian health services--public and private--are still reluctant to accept public evaluation and criticism. But with Brazil's new consumer's code the stage is set for a more active role of patients in their health decisions and for nurses and health professionals to acquiesce to consumers' dissatisfaction and respond with improved professional performance.

    Seismic surveys are an important method in prospecting for oil and gas reservoirs in the marine environment. The ELPN/IBAMA has required that companies develop an adequate social programme in parallel with the seismic surveys to establish a better interaction with the communities influenced by these operations and reduce possible negative effects. Between January and October 2003, CGG Brazil studied coastal communities in the following areas. BM-CE-1 e BM -CE-2, Ceara; Fragata, BM-ES-5 e BM-ES-6, Espirito Santo; BM BAR-1 e BM BAR-3, Maranhao and BM-C-25 and BM-C-16 off Campos basin. Communities and groups that could potentially be influenced by the surveys were visited to mitigate direct and indirect impacts. Preliminary results show that fisheries were the main group to be monitored. A standard questionnaire was used to characterize the local fisheries and interviews were held with fishermen, boat owners and members of the fishery industries (n=422). In Ceara the fishery is typically handmade and occurs in water depths up to 200 meters. The main boat propulsion is sail and the 'Cacoeira' is the most popular gear used. Off Espirito Santo, small and medium motored boats are usually used and line is the main gear among the fishermen. At Barreirinhas (Maranhao), boats are usually up to 14 meters long, and operate in water depths of up to 120 metres. Again the 'cacoeira' is the proffered gear. We concluded that Programs carried out by CGG reached their purpose. This is confirmed by low incident rate between seismic ships and the fisheries fleet. (author)

    The serum production in Brazil, the only effective treatment in cases of snakebites, uses horses that although large size, have reduced l lifespan compared with horses not immunized. Ionizing radiation has been shown as an excellent tool in reducing the toxicity of venoms and toxins isolated, and promote the achievement of better immunogens for serum production, and contributing to the welfare of serum-producing animals. It is known, however, that the effects of ionizing radiation on protein are characterized by various chemical modifications, such as fragmentation, cross-linking due to aggregation and oxidation products generated by water radiolysis. However, the action of gamma radiation on toxins is not yet fully understood structurally and pharmacologically, a fact that prevents the application of this methodology in the serum production process. So we proposed in this paper the characterization of crotamine, an important protein from the venom of Crotalus durissus terrificus species, irradiated with {sup 60}Co gamma rays. After isolating the toxin by chromatographic techniques and testing to prove the obtaining of pure crotamine, it was irradiated with gamma rays and subjected to structural analysis, Fluorescence and Circular Dichroism. Using high hydrostatic pressure tests were also conducted in order to verify that the conformational changes caused by radiation suffer modifications under high pressures. From the pharmacological point of view, muscle contraction tests were conducted with the objective of limiting the action of crotamine in smooth muscle as well as the change in the action of toxin caused structural changes to the front. Analysis of Circular Dichroism and Fluorescence showed changes in structural conformation of crotamine when subjected to gamma radiation and that such changes possibly occurring in the secondary and tertiary structure of the protein. The observed in pharmacological tests showed that the irradiated crotamine was less effective

  6. The population question in Brazil.

    Science.gov (United States)

    1992-01-01

    Population control programs were instituted in Brazil in the 1960s and resulted in as 50% reduction of the fertility rate in 20 years with a reduction in population growth from 2.9%/year in the 1960s to 2.1% in the 1980s. The rapid urbanization which has occurred in Brazil also contributed to this process. While the Brazilian government has eschewed foreign intervention, it encourages the population control programs which are funded by international agencies. The women's movement became involved in policies relating to reproductive rights in 1980, and attempts were made to change the focus of women's health care and the right of women to make reproductive choices. 71% of Brazilian women of reproductive age who are married or living in consensual union use contraception. This compares with 70% of women in developed countries. In Brazil, however, 44% of the women have been sterilized, 41% use oral contraceptives (OCs), and 12% use natural or barrier methods, compared to 7, 13, and 41%, respectively, in developed countries. Sterilization is illegal in Brazil, although it is widespread; the high number of Cesarean section births may determine a medical need for sterilization (after three such deliveries, for example). Abortion is also illegal (except in cases of rape or if the mother's life is in danger) and widespread. The 2 to 3 million abortions each year are thought to be the third cause of maternal mortality. Studies of OC use have shown that Brazilian women often use OCs without medical monitoring or in cases when the contraceptive is absolutely contraindicated. In the past few years, Brazilian women's groups have demanded that the government deal with the issue of family planning in order to stop the intervention of international population control agencies. Brazil has never had the sufficiently modern and effective policy to help women to use contraception safely during the various stages of their reproductive lives. PMID:12286343

    1981-04-01

    In this work, the main evidence and conclusions regarding geological links between Brazil and Africa are summarized, with emphasis on the geochronological aspects. Taking into account the geographical position, as well as the similarities in the geochronological pattern, the following main provinces of the two continents are correlated: The Imataca and Falawatra complexes in the Guayana Shield and the Liberian Province of West Africa. The Paraguay-Araguaia and the Rockelide Fold Belts. The Sa˜o Luiz and the West African cratonic areas. The Caririan Fold Belt of northeastern Brazil and the Pan-Africa Belt of Nigeria and Cameroon. The JequiéComplex of Bahia, the Ntem Complex of Cameroon and similar rocks of Gabon and Angola. The Ribeira Fold Belt in Brazil and the West Congo and Damara Belts in West and South Africa. In addition, other geological links are considered, such as some of the major linear fault zones which can be traced across the margins of South America and Africa, in the pre-drift reconstructions. Correlations are also made of the tectonic and stratigraphic evolution of the Paranáand Karroo syneclises, and the Brazilian and African marginal basins around the South Atlantic, during their initial stages. Finally, several similarities in the tectonic evolution of South America and Africa, during and after the onset of drifting, are shown to be compatible with a recent origin for the South Atlantic floor, as required by sea-floor spreading and continental drift between South America and Africa.

  18. 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.

  19. An AIDS campaign in Brazil.

    1987-01-01

    The Acquired Immune Deficiency Syndrome (AIDS) distribution program in Brazil, spearheaded by the National Division of Sanitary Surveillance in Ports, Airports, and Borders, was part of the government's massive education campaign to prevent the transmission of HIV-AIDS in Brazil. Beginning in February 1987, the climate was sufficiently favorable to operate a coordinated information campaign during the Carnival celebration, and tourists arriving in the cities of Brazil for the annual Carnival celebration were handed an educational brochure in Portugese, Spanish, English, and French. Yet, beyond reaching the tourist populations, it is particularly important to reach large portions of the Brazilian population. Planners of the national AIDS campaign intend to use television, radio, and all major newspapers in their effort to cover the country. Initial television coverage is comprised of short informational messages directed at high-risk groups. There also are plans to use radio and the print media in order to reach a wider audience. It is estimated that US $6 million will be needed to adequately meet the costs of AIDS prevention and medical care, but due to extreme budget constraints, only $45,000 has been earmarked for ongoing AIDS activities at this time.

    This work evaluates the economic impacts resulting from the different forms of learning resulting from the execution of national technological projects. As an example, the work mentions the technological capability in deep water production systems promote by the PETROBRAS, in the period of the years 1986-2000. Based on a prior study, seven projects have been selected by a common characteristic of non successful commercial results. The main argument shows that nevertheless the commercial throwback, these projects were in the origin of important learning processes in the company, resulting in significant indirect economic impacts. Each of the project and the economic impact are described. The data of the research referring to the project samples are presented, revealing that the economic impacts are greater than seven times the project costs.

    The 1973 energy crisis prompted the United States to suspend supplies of enriched uranium to the reactor being built in Brazil, Angra I. In 1975, the Brazil-Germany Nuclear Agreement was announced. The Programme was a failure. Today the Angra II nuclear reactor has been completed, the only reactor completed under the agreement with Germany. Brazil's last military President implemented the Parallel Nuclear Programme, which included uranium enrichment with the justification of developing the technology that had not been transferred through the Nuclear Agreement with Germany. In 1986, the existence of a deep shaft drilled by the Air Force was revealed. A Technical Report concluded that it had all the characteristics and dimensions required to test a nuclear bomb. Some years later, the Civilian Government acknowledged the existence of an underground nuclear explosion facility and symbolically sealed this shaft. The situation in Brazil has improved recently. Brazil ratified the Treaty of Tlatelolco on the denuclearisation of Latin America and established ABACC, an agency handling mutual inspections of nuclear facilities in Brazil and Argentina. Brazil also signed the Nuclear Weapons Non-Proliferation Treaty. The uranium enrichment activities are being transferred to a civilian industry. More importantly, I do not believe that the uranium enrichment project is intended to endow Brazil with the capacity to produce nuclear weapons. (author)

  9. An overview on small hydro in Brazil

    International Nuclear Information System (INIS)

    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 km2. 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.

    Cardozo Moreira, Jasmine; Muggler, Cristine Carole

    2014-05-01

    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

    2011-07-01

    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). The present paper intends to enumerate the characteristics of these reactors, their utilization and current academic research. Therefore, through this paper, we intend to collaborate on the BMR project. (author)

    Zago, M A; Costa, F F

    1985-01-01

    The data on the incidence and variability of hereditary haemoglobin (Hb) disorders in Brazil are reviewed. The most common abnormalities are HbS, HbC and beta-thalassaemias. Both homozygotes and compound heterozygotes for these genes (i.e., HbS/HbC disease, S/beta-thalassaemia, C/beta-thalassaemia) are common, owing to the free miscegenation of populations of Mediterranean and African ancestry. The diversity of beta-thalassaemias is similar to that observed in other regions. beta(0)-Thalassaemia is more frequent than the beta(+) variant among affected individuals. Most patients are descendants of Italian immigrants but occasional cases have other racial origins. Patients with thalassaemia major are mostly beta (0) homozygotes, while thalassaemia intermedia is more heterogeneous, including a variety of genotypes. alpha-Thalassaemias are not common although cases of HbH disease have been reported. Isolated examples of several Hb variants have been described, and two abnormal Hb were first found in Brazil: Hb Porto Alegre and Hb Niteroi. PMID:3898485

  16. Homosexuality and adoption in Brazil.

    Uziel, A P

    2001-11-01

    Western societies are undergoing legal and policy changes in relation to laws governing the family, marital status, sexual orientation and the welfare of children, including in Brazil where, in the 1990s, the rights of homosexuals were incorporated into ongoing debates about what constitutes a family. This paper discusses the issue of adoption of children by homosexual men in Brazil, using information from court records from 1995-2000 in Rio de Janeiro, and from interviews with two judges, five psychologists and four social workers who evaluate those wishing to adopt. It uses the case records of one man's application to adopt, in which homosexuality became a central issue. Both the construction of masculinity in relation to parenting and concepts of the family were the parameters upon which the decision to allow him to adopt or not depended. Because the legislation does not specify what the sexual orientation of would-be adoptive parents should be, it is possible for single persons to adopt if they show they can be good parents. As more single people, alone or in couples, seek to adopt, it is important to clarify the criteria for judicial decisions on adoption applications. A dialogue is therefore needed on the meaning of family and whether and how it relates to sexual orientation. It is only on this basis that the courts can take a clear decision as to whether being homosexual is a relevant issue in regard to applications to adopt or not. PMID:11765396

  20. Brazil in the global energy world

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Frank D.; Vossoughi, Shapour [University of Kansas (KU), KS (United States)

    2012-07-01

    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)

    In the last decades, wind power generation has proven its suitability to the Gigawatt scale, necessary to an effective contribution to electric systems. This paper demonstrates, from existing data, the wind / hydro seasonal complementarity in the relevant areas of Brazil, and discusses its possible effect on the feasibility of seasonal stabilization of the energy supply in the Brazilian interconnected grid, taking advantage of the country's large natural resources available. Case studies for the southern/southeastern and the northeastern regions of Brazil are presented. A brief analysis is included regarding the geographic location of the interconnected grid, main hydro power plants, and estimated promising wind farm areas in Brazil. (orig.)

  10. The role of nuclear energy in Brazil

    International Nuclear Information System (INIS)

    Electricity consumption in Brazil continues to grow at a faster rate than electricity generation, and in 1991 consumption reached 227 TWh, surpassing generation by more than 22 TWh. Thus, for Brazil to achieve its ambitious economic development plan, in addition to solving its current political and macroeconomic issues, the development and diversification of alternative energy resources remains a high priority. As early as the 1970s, Brazil began to seriously consider nuclear energy as the main alternative source of energy that could help the country meet its projected electricity requirements through the end of the century. This decision was based primarily on the fact that Brazil's known reserves of uranium are far greater in energy content than that of its coal or oil reserves

    This paper describes the Brazilian health system, which includes a public sector covering almost 75% of the population and an expanding private sector offering health services to the rest of the population. The public sector is organized around the Sistema Único de Saúde (SUS) and it is financed with general taxes and social contributions collected by the three levels of government (federal, state and municipal). SUS provides health care through a decentralized network of clinics, hospitals and other establishments, as well as through contracts with private providers. SUS is also responsible for the coordination of the public sector. The private sector includes a system of insurance schemes known as Supplementary Health which is financed by employers and/or households: group medicine (companies and households), medical cooperatives, the so called Self-Administered Plans (companies) and individual insurance plans.The private sector also includes clinics, hospitals and laboratories offering services on out-of-pocket basis mostly used by the high-income population. This paper also describes the resources of the system, the stewardship activities developed by the Ministry of Health and other actors, and the most recent policy innovations implemented in Brazil, including the programs saúde da Familia and Mais Saúde.

Despite its good financial results in 2004 with a turnover of 46.9 Mds euros its debts are around 19.7 Mds euros and are mainly due to its international investments which were not all very profitable. The first source of concern remains the Latin America markets and more particularly the Brazilian one which recorded 1.6 Md euros of losses. The future of EDF investment in Brazil, through its acquisition of the distribution company, Light, is uncertain. Within a new electric power industry framework, after currency devaluation and a rationing, Light is now in a catastrophic financial situation. The last tariff revisions given by the Brazilian authorities and the economic characteristics of the concession put the distributor at the edge of the bankruptcy. This article presents the situation of EDF group and Light at the end of 2004. The main question is the future of the Brazilian distributor in general and more particularly within the French group EDF. (author)

  16. The victory against Greenpeace-Brazil

    International Nuclear Information System (INIS)

    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.)

  17. Brazil's sugarcane boom could affect regional temperatures

    Science.gov (United States)

    Schultz, Colin

    2013-04-01

    With the world seeking to cut its dependence on fossil fuels, the use of bioethanol and other biofuels is on the rise. In Brazil, the second largest producer and consumer of bioethanol, this has led to a boom in sugarcane production. Based on new laws and trade agreements, researchers expect Brazil's production of sugarcane-derived ethanol to increase tenfold over the next decade, with considerable land being converted for growing sugarcane. Much of this expansion is expected to come at a loss of some of the country's cerrado savannas. So while a major aim of the turn to biofuels is to reduce the transfer of carbon to the atmosphere and mitigate global climate change, the shifting agricultural activity could have direct consequences on Brazil's climate by changing the region's physical and biogeochemical properties.

    2013-12-01

    Full Text Available The objective of this paper is to estimate the indirect tax burden on food for ten income classes, based on income and household total expenditure in southern Brazil. Thus it can be seen as indirect taxes on foods affect the monetary income and consumption pattern of households. To reach the objectives proposed, will be used the Pintos-Payeras (2008 model. The database iscomposed by microdata from the Household Budgeting Survey (POF 2008-2009 and the tax regulations of the country and the southern states of Brazil. The results show that indirect taxes on food in Southern Brazil is regressive when based on income and expenditure of household , ie , the poorest people pay proportionately more taxes and have their consumption pattern highest taxed ICMS (Brazilian value added tax is the tax that contributes most to the regressivity.

  20. Challenges for malaria elimination in Brazil.

    Ferreira, Marcelo U; Castro, Marcia C

    2016-01-01

    Brazil currently contributes 42 % of all malaria cases reported in the Latin America and the Caribbean, a region where major progress towards malaria elimination has been achieved in recent years. In 2014, malaria burden in Brazil (143,910 microscopically confirmed cases and 41 malaria-related deaths) has reached its lowest levels in 35 years, Plasmodium falciparum is highly focal, and the geographic boundary of transmission has considerably shrunk. Transmission in Brazil remains entrenched in the Amazon Basin, which accounts for 99.5 % of the country's malaria burden. This paper reviews major lessons learned from past and current malaria control policies in Brazil. A comprehensive discussion of the scientific and logistic challenges that may impact malaria elimination efforts in the country is presented in light of the launching of the Plan for Elimination of Malaria in Brazil in November 2015. Challenges for malaria elimination addressed include the high prevalence of symptomless and submicroscopic infections, emerging anti-malarial drug resistance in P. falciparum and Plasmodium vivax and the lack of safe anti-relapse drugs, the largely neglected burden of malaria in pregnancy, the need for better vector control strategies where Anopheles mosquitoes present a highly variable biting behaviour, human movement, the need for effective surveillance and tools to identify foci of infection in areas with low transmission, and the effects of environmental changes and climatic variability in transmission. Control actions launched in Brazil and results to come are likely to influence control programs in other countries in the Americas. PMID:27206924

    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.

    Picon, Felipe

    2012-04-01

    In the last three decades there has been a noticeable trend in the redefinition of the nuclear family in Brazil. A recent increase in the rates of divorces and paradoxically also in the rates of marriages, the legalization of same-sex unions and adoption by these couples, and the phenomenon of teenage pregnancy are some of the aspects that reflect on the current Brazilian family. This review highlights these changes and describes how family therapists in Brazil are facing the challenge of assisting these families, in a continental-sized country with uneven distribution of training courses and healthcare assistance.

    Full Text Available In its first part, the text examines the evolution of research on demographic dynamics and environmental change in Brazil. While concern for the deforestation of the Amazon region was an important starting point for the concerns of demographers, the first systematic studies dealt with the "brown agenda." It was a question of urban environmental quality which motivated specialists to enter this field. In the second part, the text presents a preliminary analysis of demographic dynamics in the principal ecological formations of Brazil, with considerations on the relationships between processes of population distribution and environmental sustainability.

  6. Hard times for Brazil's nuclear programs

    International Nuclear Information System (INIS)

    Brazilian scientists are strongly criticizing their government's ability to manage nuclear technology since the accidental release of highly radioactive cesium from a cancer therapy machine. the machine had been abandoned and was opened up by scavengers. Four people died and several others were exposed before the spill was contained. A joint statement issued by two of Brazil's main science organizations calls for the restructuring of Brazil's Commission for Nuclear Energy so that it no longer controls both the development and the regulation and licensing of nuclear energy

  7. Will Brazil's cars go on the wagon?

    International Nuclear Information System (INIS)

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

  9. Fast reactor research activities in Brazil

    International Nuclear Information System (INIS)

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

    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.

    Regardless the excellent amount of solar irradiation in Brazil, the development and production of solar water heating systems did not reach the low-income families yet. The relatively high cost of conventional solar water heaters is still the main reason to prevent it. The development of a low cost solar water heater (around US$ 200), easy technology, was the scope of previous work. All-plastic solar collector prototypes were developed using unplasticized Poly (vinyl chloride) ceiling panels and tubes, commodities from building engineering. Nevertheless, the main thermal and photo degradation mechanisms for PVC are well known; the unusual application of PVC as solar collector materials should need a specific investigation on environmental aging. This work presents a study on outdoor aging and characterization of PVC flat-plate absorber of solar collectors after 5 years on use. (author)

  13. Brazils Role in environmental governance: Analysis of possibilities for increased Brazil-Norway cooperation

    Energy Technology Data Exchange (ETDEWEB)

    Valberg, Anna Helene

    2011-07-01

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

    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.

  1. Environmental sustainability of biodiesel in Brazil

    International Nuclear Information System (INIS)

    Biodiesel production in Brazil has grown from 736 m3 in 2007 to 2.7 Mm3 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

  2. Pentecostalism and premarital sexual initiation in Brazil

    2014-06-01

    Full Text Available Pentecostal denominations in Brazil are recognized for their promotion of conservative norms and punitive sanctions related to the sexual behavior of their young members. Moreover, they have created unique space for their followers to actively participate in a religious environment. Using data from the PNDS-2006 (National Survey on the Demography and Health of Children and Women, Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher de 2006, we examine the associations, in Brazil between religion, as measured by religious affiliation and attendance at religious services, and premarital adolescent sexual initiation. Our main results confirm a strong association between delay in sexual initiation and Pentecostalism in Brazil and suggest that this association be related to frequent attendance at religious services. These findings are intriguing, especially because Pentecostalism has emerged and concentrated among socioeconomically disadvantaged populations, including the least-educated women, with lower income, and residents of urban areas. We conclude by suggesting that religion may be taking the place of family and school in communication on adolescent sexual behavior in Brazil. This hypothesis should be carefully investigated, since the religious teachings may sometimes be in favor of what families and the state see as beneficial for adolescents and youth in general, but sometimes in disaccord.

    Directory of Open Access Journals (Sweden)

    Alves Rômulo RN

    2011-07-01

    Full Text Available Abstract Ancient connections between animals and human are seen in cultures throughout the world in multiple forms of interaction with the local fauna that form the core of Ethnozoology. Historically, ethnozoological publications grew out of studies undertaken in academic areas such as zoology, human ecology, sociology and anthropology - reflecting the interdisciplinary character of this discipline. The rich fauna and cultural diversity found in Brazil, with many different species of animals being used for an extremely wide diversity of purposes by Amerindian societies (as well as the descendents of the original European colonists and African slaves, presents an excellent backdrop for examining the relationships that exist between humans and other animals. This work presents a historical view of ethnozoological research in Brazil and examines its evolution, tendencies, and future perspectives. In summary, literature researches indicated that ethnozoology experienced significant advances in recent years in Brazil, although from a qualitative point of view improvement is still needed in terms of methodological procedures, taxonomic precision, and the use of quantitative techniques. A wide range of methodologies and theories are available in different areas of learning that can be put to good use in ethnozoological approaches if the right questions are asked. The challenges to studying ethnozoology in Brazil are not insignificant, and the tendencies described in the present study may aid in defining research strategies that will maintain the quantitative growth observed in the recent years but likewise foster needed qualitative improvements.

  13. Abortion in Brazil: legislation, reality and options.

    Science.gov (United States)

    Guedes, A C

    2000-11-01

    Abortion is illegal in Brazil except when performed to save the woman's life or in cases of rape. This paper gives a brief history of parliamentary and extra-parliamentary efforts to change abortion-related legislation in Brazil in the past 60 years, the contents of some of the 53 bills that have been tabled in that time, the non-governmental stakeholders involved and the debate itself in recent decades. The authorities in Brazil have never assumed full public responsibility for reproductive health care or family planning, let alone legal abortion; the ambivalence of the medical profession is an important obstacle. Most politicians avoid getting involved in the abortion debate, but the majority of bills in the 1990s have favoured less restrictive legislation. Incremental legislative and health service changes could help to improve the situation for women. Advocacy is probably the most important action, to promote an environment conducive to change. Clandestine abortion is a serious public health problem in Brazil, and the inadequacy of family planning services is one of the causes of this problem. The solutions should be made a priority for the Brazilian public health system. PMID:11424252

  14. Status of Research Reactor Utilization in Brazil

    International Nuclear Information System (INIS)

    Brazil has four research reactors in operation: the IEA-R1, a pool type research reactor of 5 MW; the IPR-R1, a TRIGA Mark I type research reactor of 100 kW; the ARGONAUTA, an Argonaut type research reactor of 500 W; and the IPEN/MB-01 a critical facility of 100 W. Research reactor utilization has more than fifty years in Brazil. The first three reactors, constructed in the late 50's and early 60's at university campus in Sao Paulo, Belo Horizonte and Rio de Janeiro, had their utilization for training, teaching and nuclear research. The IPEN/MB-01, designed and constructed in IPEN in the late 80's, is utilized for the development and qualification of reactor physics calculation for PWR core application. The IEA-R1 has had its application and utilization increased through the years and it is presently used for radioisotope production, neutron beam application, neutrongraphy, neutron activation analysis, and limited fuel and material irradiation tests, besides the regular use for training and teaching. The low power of the reactor and the lack of hot cells for post irradiation analysis limits its technical application for the nuclear fuel industry. Brazil has two nuclear power plants in operation, one unit starting construction and four more units planned for the next two decades. Brazil has significant quantities of uranium ore and has expertise in all the fuel cycle steps, including uranium enrichment, and produces the fuel assemblies for the nuclear power plants. These industrial activities demand the need of material and fuel irradiation tests. IPEN produces radiopharmaceutical kits for the treatment of more than three million patients each year. The majority of the radiopharmaceutical kits is produced from imported radioisotopes. The increasing price and shortage of world supply of 99mTc leads also to the need of increasing the radioisotope production in Brazil. Due to these new demands, the Brazilian Nuclear Energy Commission is analyzing the costs and benefits

  15. Biochar: An emerging policy arrangement in Brazil?

    International Nuclear Information System (INIS)

    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.

    1997-01-01

    The increase in the consumption of tropical nuts in the Northern Hemisphere during the last years, has evolved in a simultaneous enhancement of allergic IgE mediated (Hypersensitivity type 1) reported cases produced by this kind of food. The Brazil nut is the seed of the Bertholletia excelsa tree (Family Lecythidaceae) and, as in other seeds, proteins represent one of its major components making up 15-17% of its fresh weight and 50% of defatted flour. Of these, storage proteins are the most important ones, and the 12 S globulin legumin-like protein and the 2 S albumin have been described as the most representative. The 2 S protein, due to its high sulfur-rich amino acid content (3% cysteine and 18% methionine), is being studied, cloned and expressed in some important agronomic seeds (soybean, bean, oilseed rape) in order to enrich the nutritional quality of them. The case of a patient with serious clinical allergic symptoms (vomiting, diarrhoea and loss of consciousness) caused by oral contact with the Brazil nut, is presented. The patient gave a positive Skin Prick Test response to Brazil nut, kiwi and hazelnut extracts, and negative to regionally specific aeroallergens and other food extracts. The patient serum showed a high level of specific IgE by RAST to Brazil nut (> 17.5 PRU/ml, Class 4), and significative levels to hazelnut, and mustard. In vitro immunological studies (SDS-Immunoblotting and IEF-Immunoblotting) revealed IgE-binding proteins present in the extract. It was shown that not only the heavy (Mr 9) and light (Mr 4) subunits of the known allergenic 2 S albumin but also the alpha-subunits (Mr approximately 33.5 and 32) and at least one of the beta-subunits (Mr approximately 21) of the 12 S Brazil nut globulin, hitherto never involved in allergic problems, showed a strong IgE-binding capacity.

    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.

  2. Argentina and Brazil: an evolving nuclear relationship

    International Nuclear Information System (INIS)

    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)

    2011-12-01

    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.

    This project consists in mapping a 4-square-degree region searching for exoplanets using the transit method. This “mini-survey” will be the first use of the 16″ robotic telescope developed by Universidade Federal de Santa Catarina (UFSC-Brazil) and Laboratório Nacional de Astrofísica (LNA/MCT-Brazil). The chosen region is over the Columba constellation and our first observations have shown that we have enough signal-to-noise ratio to search for transits on about 20,000 stars with ~13 < I < 16 mag, a magnitude range between the OGLE and HAT projects. In this star sample we expect to find about a dozen planets with transits duration of 1-3 hours and magnitude depth from 0.001 to 0.010 mag. As for other projects, all information will became public as a VO service.

    2016-01-01

    Full Text Available Zika vírus, a Flavivirus first isolated in Africa, has spread to many countries around the world including Brazil. In this country, seven months after the football world cup, it was registered the occurrence of a epidemic, subsequently related to cases of microcephaly and Guillain-Barré syndrome. The virus is transmited via mosquito from Aedes genus, often following the bite from an infected vector. The febrile disease is self-limited, and there is no specific treatment. Few months after this outbreak in Brazil, the authorities recognized the relationship between the Zika vírus and the occurrence of Guillain Barré syndrome and microcephaly in newborns, correponding to fetal cerebral malformation or brain lesions. This finding is being a worldwide alert for strengthening the preventive measures, restricted to prevent insect bites and care for the environment.

  6. The legacy of monazite processing in Brazil

    International Nuclear Information System (INIS)

    The exploitation of natural resources containing naturally occurring radionuclides may lead to enhanced levels of radioactive isotope and enhanced potential for exposure to naturally occurring radionuclides in products, by-products, residues or wastes. Such resources include, for instance, monazite, the processing of which, in Brazil, generated a great amount of radioactive residues, being stored in buried concrete tanks, in temporary storage buildings and in sealed trenches. In addition, during the 1980's there were no radiological protection rules concerning the storage and transportation of these kinds of residues. Mineral radioactive residues were used as landfills and the residues of chemical processes contaminated floors and buildings. The decommissioning process and cleaning of old plants have generated tons of wastes that has been added to previously produced wastes. This paper reports and discusses the cycle of monazite in Brazil and its consequences in terms of site remediation and amount of wastes and residues generated and stored. (authors)

    The Maytenus ilicifolia (espinheira-santa) is a popular medicinal plant with different uses. It is native of South America and can be found in Brazil. In the Brazilian market it is possible found products labeled as M. ilicifolia. So far, the studies published in the literature involve the modification of the natural materials and do not concern the comparison between commercial the raw natural materials. Different non-destructive NMR techniques can be used to study natural materials. In this work it is presented a characterization study by Fast Field Cycling of the {sup 1}H spin-lattice relaxation time (T{sub 1}) NMR, in the frequency range 100 khz-10 MHz. The results obtained in two commercial M. ilicifolia samples and one control sample collected in natura are compared. It was intended to study the possibility to elaborate a characterization method using FFCNMR suitable for the verification of authenticity and/or evaluation of tampering on products. The differences detected by FFCNMR relaxometry were confirmed by thermogravimetric analysis and infrared spectroscopy. (author)

    Dosimetric materials that can be produced in Brazil with material acquired in the national market to replace the imported dosimeters used in radiation processing were developed in this work. Mixtures of potassium nitrate and sensitizers compounds as manganese dioxide, barium nitrate and potassium bromide were prepared in the pellet form. Dosimetric characteristics such as dose-response useful range, sensitivity, environmental conditions and dose rate influences were evaluated in {sup 60}Co gamma radiation fields. Dyed polymethylmethacrylate detectors were also produced and its dosimetric characteristics were evaluated. The main characteristics evaluated in this case were: dose response useful range sensitivity, environmental conditions, dose rate influences and radiation energy dependence in gamma radiation fields and accelerated electrons beam of 0.8 to 1.5 MeV. The applied analytic technique was spectrophotometry. The calibration was performed in the irradiation facilities belonging to IPEN and certified by the International Atomic Energy Agency by means of the program IDAS (International Dose Assurance Service ) using the Fricke dosimeter. The mixture of potassium nitrate and manganese dioxide presented the best results and a wide dose range between 200 and 600 kGy. The response of the developed polymethylmethacrylate detectors are similar to the imported detectors and the dose range is characteristic to each detector and depends on the dye added in its formulation.

    The aim of this work is to examine by means of characterization and dating pottery recently discovery inside archaeological sites recognized with circular earth structure in Acre State - Brazil which may contribute to the research in the reconstruction of part of the pre-history of the Amazonic Basin. These sites are located mainly in the Hydrographic Basin of High Purus River. Three of them were strategic chosen which provide the ceramics: Lobao, in Sena Madureira County at north; Alto Alegre, in Rio Branco County at east and Xipamanu I, in Xapuri County at south. The X-ray diffraction mineral analysis made possible to identify two types of crystal structures of ceramic minerals: quartz and M-Kaolinite. Neutron activation analysis in conjunction with multivariate statistical methods were applied for the ceramic characterization and classification. An homogeneous group was established by all sherds collected from Alto Alegre and was distinct from all the other two groups analyzed. Some of the sherds collected from Xipamanu I appeared in Lobao's urns, probably because they had the same fabrication process. The Lobao's urns presented a homogeneous group. Geochronology of these materials was carried out by Thermoluminescence. The Xipamanu I was the oldest site and Lobao the youngest. The average age of Xipamanu I and Alto Alegre were 2600 and 2070 years respectively. The average age of of occupation was 400 years to Alto Alegre and 970 years to Xipamanu I. The most probably date for Lobao was 1880 years. (author)

    Acute viral infections of the central nervous system (CNS) such as acute flaccid paralysis, meningitis, and encephalitis, are responsible for a high morbidity, particularly in children. Non-Polio enteroviruses (NPEV) are known to be responsible for over 80% of viral meningitis in which the etiologic agent is identified. In the present study, we show the frequency of enterovirus meningitis in Brazil from December 1998 to December 2003. Enterovirus were isolated from 162 (15.8%), of a total of 1,022 cerebrospinal fluid (CSF) specimens analyzed. Echovirus 30 was identified in 139 of these isolates (139/162-85.2%). Other identified enteroviruses were: Coxsackievirus B5 (3.7%), Echovirus 13 (3.7%), Echovirus 18 (3%), Echovirus 6 (1.2%), Echovirus 25 (1.2%), Echovirus 1 (0.6%), and Echovirus 4 (0.6%). Patients's age ranged from 28 days to 68 years old. The most frequent symptoms were fever (77%), headache (69.5%), vomiting (71.3%), neck stiffness (41.3%), convulsion (7.1%), and diarrhea (3.7%). Although, the majority of the patients recovered without any complication or permanent squeal, five deaths occurred. Throughout the surveillance period, five viral meningitis outbreaks were confirmed: four in the Southern Brazil and one in the Northeast Brazil. Echovirus 30 was responsible for four out of the five outbreaks while Echovirus 13 caused the fifth one. Besides the outbreaks, 734 sporadic cases were also identified during the study period and 59 of these were positive for virus isolation (8%). Echovirus 30 accounted for 70% of the isolates. Our results showed that Echovirus 30 was the most prevalent etiological agent of viral meningitis in Brazil, causing both outbreaks and sporadic cases. PMID:16299728

MATERIAL AND METHODS: This is a descriptive research with a qualitative approach. Interviews were conducted with undergraduate students, graduates, professors, staff and managers from bachelor degrees in Biochemistry at UFV, UFSJ and UEM. The sampling procedure was non probabilistic for judgment (choice of the subjects involved and interested in the course of biochemistry to undergraduate students, graduates, professors and staff and non probabilistic for convenience to managers. The qualitative assessment to depict the representative keywords was performed using words cloud by WordleTM. RESULTS: The study included 5 managers, 24 professors, 12 staff, 25 undergraduate students, 5 graduates. For the students the main reason for the course selection should be scientific vocation and affinity with chemistry and biology; most cited positive parameters were faculty and great structure, practical classes and broad playing field; most cited negatives were high mandatory disciplines, little student free time and lack of sophisticated equipment. Despite the conception of the programs have happened in different contexts and regions we noted similarities deficiencies and distresses. CONCLUSION: Difficulties must be

  14. Nuclear power plant safety in Brazil

    International Nuclear Information System (INIS)

    The Code of Practice for the Safe Operation of Nuclear Power Plants states that: 'In discharging its responsibility for public health and safety, the government should ensure that the operational safety of a nuclear reactor is subject to surveillance by a regulatory body independent of the operating organization'. In Brazil this task is being carried out by the Comissao Nacional de Energia Nuclear in accordance with the best international practice. (orig./RW)

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 i...

  17. Costs comparison of electric energy in Brazil

    International Nuclear Information System (INIS)

    A cost comparison study of various sources of electric energy generation was performed using uniform analysis criteria. The results indicate higher costs for coal, followed by nuclear and hidro. It was verified that presently, large hidro-power plants can only be located far from the load centers, with increasing costs of hidro-power energy in Brazil. These costs become higher than the nuclear plant if the hidro plant is located at distances exceeding 1000 Km. (Author)

    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. PMID:27050309

  4. Oil refining expansion criteria for Brazil

    International Nuclear Information System (INIS)

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

    This article discusses the achievements and challenges that England and Brazil face in relation to their capacity to address inequalities in health through health promotion and public health policies. Using secondary data (policy texts and related documents), this article contextualizes, explains, and critically appraises health promotion and public health efforts for the reduction of inequalities in health in the 2 countries. A historic documentary analysis was undertaken, with hermeneutics as the methodological framework. The global economic crisis has prompted the so-called developed economies of Europe to reconsider their economic and social priorities. England represents a state facing this kind of challenge. Equally, Brazil is assuming new positions not only on the world stage but also in terms of the relationship it has with its citizens and the priorities it has for state welfare. The United Kingdom continues to finance a health care system allowing universal access in the form of the National Health Service, and state concern about the public health task of reducing inequalities has recently been underlined in policy. For Brazil, although there have been recent achievements related to population access to healthcare, challenges continue, especially with regard to the quality of care. PMID:26077860

    2009-01-01

    Molecular phylogenetic studies have become a major area of interest in plant systematics, and their impacts on historical biogeographic hypotheses are not to be disregarded. In Brazil, most historical biogeographic studies have relied on animal phylogenies, whereas plant biogeographic studies have largely lacked a phylogenetic component, having a limited utility for historical biogeography. That country, however, is of great importance for most biogeographic studies of lowland tropical South America, and it includes areas from a number of biogeographic regions of the continent. Important biogeographic reports have been published as part of phylogenetic studies, taxonomic monographs, and regional accounts for small areas or phytogeographic domains, hut the available information is subsequently scattered and sometimes hard to find. In this paper we review some relevant angiosperm biogeographic studies in Brazil. Initially we briefly discuss the importance of other continents as source areas for the South American flora. Then we present a subdivision of Brazil into phytogeographic domains, and we cite studies that have explored the detection of biogeographic units (areas of endemism) and how they are historically related among those domains. Examples of plant taxa that could be used to test some biogeographic hypotheses are provided throughout, as well as taxa that exemplify several patterns of endemism and disjunction in the Brazilian angiosperm flora.

  7. Energy requirements of households in Brazil

    International Nuclear Information System (INIS)

    In this study we determine the total (direct plus indirect) energy requirements of a given set of Brazilian households. We use a generalized input-output model in order to calculate the energy embodied in goods and services purchased by households of different income level in 11 capital cities of Brazil. Our results show that, on average, the total energy intensity of household expenditure increases with income level, although there is a considerable spread in energy intensities within income classes as well as disparities between regions of the country. The total yearly average energy requirement per household in Brazil in 1995-96 was 173.6 GJ (61% of which was indirect), with 32.8 GJ for the lower income level (66% of which was indirect), and 602.2 GJ for the higher income level (62% of which was indirect). Of this total average energy requirement, 76% was required for only three consumption categories: utilities (31%), mobility (28%) and shelter (17%). This analysis calls for the attention that has to be given not only to the direct energy consumption (as motor fuels and electricity, for example) but also to the consumption categories that encompass an important part of the indirect energy requirement of households in capital cities in Brazil

    Full Text Available Abstract INTRODUCTION: Hepatitis C is a public health problem of global dimensions, affecting approximately 200 million people worldwide. The main objective of this study was to estimate the incidence rate of hepatitis C in Brazil during the period between 2001 and 2012. METHODS: An epidemiological, temporal, and descriptive study was performed using data from the Information System for Reportable Diseases. RESULTS: Between 2001 and 2012, a total of 151,056 hepatitis C cases were recorded, accounting for 30.3% of all hepatitis notifications in Brazil. The average gross coefficient for the analysis period was 6.7 new cases per 100,000 inhabitants. The regions with the highest rates were the Southeast region (8.7 new cases/100,000 inhabitants and the South (13.9 new cases/100,000 inhabitants. There was a predominance of men with respect to the incidence rate (8.0 new cases/100,000 inhabitants compared to women (5.5 new cases/100,000 inhabitants. Injection drug use was the most common source of infection, and members of the white race, residents of urban areas, and those aged 60 to 64 years had the highest incidences. CONCLUSIONS: Over the last 10 years, the incidence of hepatitis C in Brazil has increased, mainly in the South and Southeast. The adoption of fast, accurate diagnostic methods, together with epidemiological awareness, can facilitate early intervention measures for adequate control of the disease.

  9. Noise in large cities in Brazil

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

    Movement of livestock production within a country or region has implications for genetics, adaptation, well-being, nutrition, and production logistics, particularly in continental-sized countries, such as Brazil. Cattle production in Brazil from 1977 to 2011 was spatialized, and the annual midpoint of production was calculated. Changes in the relative production and acceleration of production were calculated and spatialized using ARCGIS®. Cluster and canonical discriminant analyses were performed to further highlight differences between regions in terms of cattle production. The mean production point has moved from the Center of Minas Gerais State (in the southeast region) to the North of Goiás State (in the Midwest region). This reflects changes in environmental factors, such as pasture type, temperature and humidity. Acceleration in production in the northern region of Brazil has remained strong over the years. More recently, “traditional” cattle-rearing regions, such as the south and southeast, showed a reduction in growth rates as well as a reduction in herd size or internal migration over the period studied. These maps showed that this movement tends to be gradual, with few regions showing high acceleration or deceleration rates. PMID:26814797

    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.

    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.

  13. The problems of nutrition in Brazil.

    Low income is the factor most often associated with the existence of malnutrition. Malnutrition in Brazil is more frequently found among Brazilians with less than 2 minimum salaries/family and who live in the less developed parts of the country. In 1976, 59.2% of urban residents earned 2 or less minimum salaries. A study found that those rural residents engaged in agriculture on their own or someone else's property were better paid than those who live from salaried labor alone; temporary salaried workers are the largest rural class in Brazil and have the lowest levels of nutrition. In urban areas the informal sector represent the lowest nutrition level group. The issue of food consumption by the lower classes is linked to 4 aspects of Brazilian development: 1) structure of food production, 2) distribution of income, 3) government attempts to influence prices and marketing systems, and 4) the role of government food supplementation programs. Brazil suffers today from unbalanced growth among its various economic sectors and regions, inequitable income distribution, and inadequate public services. The misconception of the necessity of a large industrial base for development resulted in the neglect of the rural sector and thus higher malnutrition. Recent regulatory efforts by the government have begun to increase rural production, but production of agricultural exports has increased at a much more rapid pace than that of domestic food commodities. Small farmers have not taken advantage of new financial opportunities offered by the government to balance production levels because: 1) banks do not have enough for the demand, 2) access to the small producer of foods is difficult, and 3) the present hesitation to risk his few possessions. The largest percentage of income in Brazil goes to the richest classes and the economy is oriented towards meeting the demands of the more prosperous classes. The government's program of minimum support prices has not been successful in

    In the early 1990's, the first illicit trafficking of nuclear and radioactive materials was observed mainly in Europe. A decade marked by numerous cases of seizures of these materials. As a result, these events have become the subject of criminal forensic investigations and develop from there, nuclear forensics. In Brazil there are no illicit trafficking official records of nuclear material, however, is widely known the extraction and illegal transportation of radioactive geological materials, and the materials pieces attachment used as shielding for radioactive sources. One of the main tools used in nuclear forensics is the nuclear materials databases establishment. These documents must contain the most information as possible about the physical, chemical and nuclear material seized, allowing the identification of their origin, manufacturing process or age. Thus, it sets characteristic composition standards of each material, called 'chemical signatures' (chemical finger print). In this work nuclear forensic protocol was adopted as well as the three stages of assessment suggested by International Atomic Energy Agency (IAEA) in identifying the origin of uranium silicide (U{sub 3}Si{sub 2}). Assays were performed in order to make physical, chemical and isotopic characterization of the studied materials and compared the data with those obtained for other uranium compounds (Uranium tetrafluoride, UF{sub 4}; uranium oxide, UO{sub 2} and U{sub 3}O{sub 8}; Yellow cake) by establishing a characteristic signature for each one. Through the assays the uranium compounds were classify by origin groups, as far as they are from different manufactured process and/ or origin. It was also possible to show the importance of a nuclear forensic database during an investigation of a nuclear forensic event. (author)

    The determination of the hydraulic properties of an alluvial soil in Cajueiro reservoir has been carried out in two experimental plots of 3.5 m x 3.5 m, installed in the opposite banks of the brook in which is located the dam, (Tuparetama Country, Pernambuco). For the determination of the hydraulic conductivity as a function of the soil water volumetric content K({theta}), the internal driainage method proposed by Hillel et al. (1972) has been applied. The soil-water retention curves h ({theta}) have been determined through the experimental data of volumetric water content and pressure obtained in field experiments. The h ({theta}) and K ({theta}) curves have been fitted to van Genuchten's closed - form equations (1980), using the Burdine's model, and Brooks and Corey's model, respectively. The volumetric water content, matric potential, and total water content estimates have been fitted to two analytical functions: one being composed by the addition of three exponentials terms the other composed and by representation the reverse of the power functions. The latter has been preferred due to its smoother representation between the fast and the slow its drainage phases. Considering the hydraulic behavior, three different layers have been identified in the soil profiles of the two experimental parcels A2 and B4 in the alluvial soil Cajueiro reservoir. The second layer of the soil profile in parcel A2 turned out the more pemeable than the other two layers. As to the soil profile in parcel B4, the first layer turned out more conductive than the other layers. However, the biggest volumetric water content variations were due to the differences found in the texture and structure of the soil profiles under study. The hydrodynamic characterization of the two soil profiles, A2 and B4, brings significant elements for the simulation of scenarios related to the soil of water transport processes. It is of particular importance the study of scenarios related to the shallow soil layers, which are conditioning to agricultural developments and soil conservation. These studies are aimed at efficient crops management while the water level in the reservoir drops down. (author)

    The identification and characterization of the hydrochemistry of the groundwaters has been done for seven wells. The sampling occurred during three bimonthly campaigns. The results classified the waters as of the calcium bicarbonated type for the majority of the samples, except for one well, whose composition is of the sodium bicarbonated type. The major ions found and how they determine the quality parameters are consistent with the reactions of mineral dissolution of the majority of volcanic rocks and the reactions with intrusion of alkaline rock in only one well. Anomalous values of nitrate in some wells alert to the impact of especially polluting sources at the time the reservoirs of the hydroeletric plant were formed. (author)

    Detailed stratigraphic analysis of the Early Permian Rio Bonito and Palermo Formations of the Parana Basin in the region of Sao Gabriel County has been used for a study on reservoir characterization of paralic sandstones. Two main depositional systems were recognized, a fluvial-dominated delta system and a wave-dominated barrier island system. The succession is divided in two third-order depositional sequences, enclosing thirteen fourth-order para sequences. This high-resolution stratigraphic framework was the base for a multi scale approach on reservoir characterization of the sandstone bodies. Reservoir heterogeneities are discussed, staring from the scale of depositional sequence (heterogeneity level 1), passing down to heterogeneity at the scale of systems tracts (heterogeneity level 2) and finalizing with an approach at para sequence scale (heterogeneity level 3). Main control on heterogeneity at the first level is base-level variation as generating mechanism for un conformities at the sediment type and rate. At the second level, the reservoir heterogeneity is controlled by the lateral and vertical variations in thickness of particular systems within the different systems tracts, and at the third level, the heterogeneity occurs controlling reservoir continuity and connectivities between reservoirs. The study supplies a model which is useful as a predictive tool for similar geologic settings in producing oil fields. (author)

    The metrological coherence among standard systems is a requirement for assuring the reliability of dosimetric quantities measurements in ionizing radiation field. Scientific and technologic improvements happened in beta radiation metrology with the installment of the new beta secondary standard BSS2 in Brazil and with the adoption of the internationally recommended beta reference radiations. The Dosimeter Calibration Laboratory of the Development Center for Nuclear Technology (LCD/CDTN), in Belo Horizonte, implemented the BSS2 and methodologies are investigated for characterizing the beta radiation fields by determining the field homogeneity, the accuracy and uncertainties in the absorbed dose in air measurements. In this work, a methodology to be used for verifying the metrological coherence among beta radiation fields in standard systems was investigated; an extrapolation chamber and radiochromic films were used and measurements were done in terms of absorbed dose in air. The reliability of both the extrapolation chamber and the radiochromic film was confirmed and their calibrations were done in the LCD/CDTN in {sup 90}Sr/{sup 90}Y, {sup 85}Kr and {sup 147}Pm beta radiation fields. The angular coefficients of the extrapolation curves were determined with the chamber; the field mapping and homogeneity were obtained from dose profiles and isodose with the radiochromic films. A preliminary comparison between the LCD/CDTN and the Instrument Calibration Laboratory of the Nuclear and Energy Research Institute / Sao Paulo (LCI/IPEN) was carried out. Results with the extrapolation chamber measurements showed in terms of absorbed dose in air rates showed differences between both laboratories up to de -I % e 3%, for {sup 90}Sr/{sup 90}Y, {sup 85}Kr and {sup 147}Pm beta radiation fields, respectively. Results with the EBT radiochromic films for 0.1, 0.3 and 0.15 Gy absorbed dose in air, for the same beta radiation fields, showed differences up to 3%, -9% and -53%. The beta

    The main dosimetric properties of jade and of Brazilian silicates of the jade family were studied for application in radiation dosimetry of high doses. Jade is a common denomination of two different silicates: jadeite, Na Al(Si{sub 2}O{sub 6}), and nephrite, Ca{sub 2}(Mg, Fe){sub 5}(Si{sub 4}O{sub 11}){sub 2} (OH){sub 2}, that belong to the subclasses of the pyroxenes and amphiboles respectively. The jade samples studied in this work were from: Austria, New Zealand, United States and Brazil. The Brazilian silicates of the jade family studied in this work were the amphiboles: tremolite,Ca{sub 2}Mg{sub 5}(Si{sub 4}O{sub 11}){sub 2}(OH){sub 2} e actinolite, Ca{sub 2}Fe{sub 5}(Si{sub 4}O{sub 11}){sub 2}(OH){sub 2}; and the pyroxenes: rhodonite, MnSiO{sub 3} and diopside, Ca Mg(Si{sub 2}O{sub 6}). The mineralogical and chemical composition of these materials were obtained using the neutron activation analysis and X-ray diffraction techniques. The main dosimetric properties (emission curves, calibration curves, reproducibility, lower detection limits, angular and energy dependence, etc) were studied using the thermoluminescent (T L), thermally stimulated exo-emission (TSEE) and electronic paramagnetic resonance (EPR) techniques. The jade-Teflon and the silicate-Teflon samples present two T L peaks around 115 deg C (peak 1) and 210 deg C (peak 2). The calibration curves of the studied materials present a linear behaviour between 0.5 Gy and 1 kGy. The TSEE emission peak occurs at 240 deg C for all samples, and the calibration curves present a sub linear behaviour between 100 Gy and 20 kGy. In the case of the EPR technique, only jade USA has a potential application for radiation dosimetry. A static computational simulation of the most probable intrinsic and extrinsic defects in rhodonite was also realized. Among the basic defects, the Schottky defects of rhodonite are the most probable to occur and, among the extrinsic defects, the divalent and trivalent dopants present the

    Full Text Available ABSTRACTIntroduction:It is known that a single prevention strategy is not enough to control multiple HIV epidemics around the world and in Brazil. However, it is not only necessary to recognize the importance of condoms as part of the policy of HIV/AIDS prevention but also discuss its limits. In this article, we aim to investigate the use of condoms in Brazil, draw critical reflections, and understand how they can once again be highlighted in Brazil's prevention strategy going forward.Methods:A narrative review of literature was conducted using keywords in PubMed. Reports from national surveys that guide the epidemiological and behavioral surveillance of the Brazilian Ministry of Health were also included.Results:A total of 40 articles and 3 reports were included in the review and 11 intervention studies to promote the condom use; the main findings were as follows: 1 Despite the increase in national studies on sexual behavior, little attention is given to the role of condom use; 2 There are few studies examining the factors associated with condom use among key populations such as men who have sex with men (MSM, female sex workers (FSW, drug users (DU, and transvestites and transexuals (TT, while substantial studies focus on adolescents and women; 3 Evidence suggests that a combination of interventions is more effective.Discussion:new prevention technologies must not lose sight of the critical importance of condoms, and efforts to reintroduce them should focus on the role of pleasure in addition to their potential to minimize the risk of HIV.

    Full Text Available OBJECTIVES: To assess epidemiologic characteristics of penile cancer in Brazil. MATERIALS AND METHODS: From May 2006 to June 2007, a questionnaire was distributed to all Brazilian urologists. Their patients' clinical and epidemiological data was analyzed (age, race, place of residence, history of sexually transmitted diseases, tobacco smoking, performance of circumcision, type of hospital service, as well as the time between the appearance of the symptoms and the diagnosis, the pathological characteristics of the tumor (histological type, degree, localization and size of lesion, stage of disease, the type of treatment performed and the present state of the patient. RESULTS: 283 new cases of penile cancer in Brazil were recorded. The majority of these cases occurred in the north and northeast (53.02% and southeast (45.54% regions. The majority of patients (224, or 78.96% were more than 46 years of age while only 21 patients (7.41% were less than 35 years of age. Of the 283 patients presenting penile cancer, 171 (60.42% had phimosis with the consequent impossibility to expose the glans. A prior medical history positive for HPV infection was reported in 18 of the 283 cases (6.36%. In 101 patients (35.68% tobacco smoking was reported. The vast majority of the cases (n = 207; 73.14% presented with tumors localized in the glans and prepuce. In 48 cases (16.96% the tumor affected the glans, the prepuce and the corpus penis; in 28 cases (9.89% the tumor affected the entire penis. The majority of the patients (n = 123; 75.26% presented with T1 or T2; only 9 patients (3.18% presented with T4 disease. CONCLUSION: Penile cancer is a very frequent pathology in Brazil, predominantly affecting low income, white, uncircumcised patients, living in the north and northeast regions of the country.

  16. Journalism as a profession in Brazil

    Directory of Open Access Journals (Sweden)

    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.

    1987-01-01

    Demographic developments and family planning in China and Brazil are described and compared. Postrevolutionary China was characterized by initial rapid economic expansion, followed later by recurrent agricultural crises. Abortion and sterilization were strictly forbidden. The mid-twenties was legal minimum age for marrying, thus increasing the work force. In the early 1960s, population control measures were introduced, legalizing sterilization and abortion, a trend reversed, in 1966, by the cultural revolution, which resulted in a baby boom and an enormous proportion of young women, today, in their reproductive ages. Various stages of increased government involvement finally resulted in a 1 family, 1 child policy adopted in 1978, coercing families and individuals to sign a certificate, severely limiting earning potentials and privileges, if having more than 1 child. By the year 2050, if current policies are being enforced, the population is projected to be 917 million. Brazil traditionally has had an intellectual pro-natality movement, due to its vast internal space, low population density and high economic productive capacity. By 1970, however, the economic miracle had passed. Child mortality and health problems became rampant. Democratizing access to contraceptive means and services, and the economic for migration to large empty spaces of the country were emphasized. The state assumed responsibility for providing contraceptive means instead of leaving it in the hands of private agencies. Brazil refuses to recognize simplistic rhetoric blaming population increases for all ills in the developing countries and espouses the position that planning for children, the more positive term for family planning, is a fundamental right of all human beings and should stem from free and informed choice by couples and individuals.

  18. Fishers' knowledge and seahorse conservation in Brazil

    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

    We present geoprocessing techniques to monitor and analyse earthquakes in Brazil. We constructed a georeferenced database called SIGSIBRA using PostgreSQL + PostGIS softwares, and fed by information from the SISBRA earthquake catalog, IBGE geographical data and CPRM geological data. The SISBRA catalog was built from the book "Sismicidade Brasileira" (Berrocal et al, 1984), updated with the Brazilian seismic bulletins from the Brazilian Geophysical Journal up to 1995, and especially with the data from seismographic monitoring activities of the University of Brasília-SIS/UnB, the Federal University of Rio Grande do Norte-UFRN, the University of Sao Paulo-USP and the Institute for Technological Research (IPT). Earthquakes occur in Brazil with moderate to low magnitudes. Besides natural earthquakes, seismic activity triggered by water dams must also be monitored. With the growing number and size of Brazilian dams (because of the many rivers, favorable topography and "clean" energy) concern with reservoir triggered seismicity is expected to increase. Approval for the construction of a hydropower plant requires seismic hazard assesmment prepared by an interdisciplinary team, with a large contribution of geoprocessing specialists. Therefore, it is important to study the characteristics of this seismicity, so that these professionals can avoid or mitigate potential environmental and social harm to communities on the margins of large dams. Thus the SIGSIBRA system can generate spatial analysis of its events, such as intensity estimation of "Kernel" points distribution; spatial statistics; spatial autocorrelation (Morans I) and correlations with geological structures, making it possible to characterize important aspects of the Brazilian seismicity. Finally, we show the statistical analysis of the database through the program ZMAP and estimate the intraplate seismogenic zones in Brazil.

  20. Social impacts of Brazil's Tucurui Dam

    International Nuclear Information System (INIS)

    The Tucurui Dam, which blocked the Tocantins River in 1984 in Brazil's eastern Amazonian state of Para, is a continuing source of controversy. Most benefits of the power go to aluminum smelting companies, where only a tiny amount of employment is generated. 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

    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.

    1995-01-01

    Sterilization in Brazil is discussed in a racial context and contrasted with the experience of the United States, demonstrating the historical differences between these two societies regarding race relations and reproductive rights. The American feminist Angela Davis referred to the control of fertility as genocide, especially as practiced in the first half of the 20th century. In 1906 President Theodore Roosevelt characterized the drop of White fertility caused by rapid urbanization as racial suicide. In 1932 the development of the eugenic movement resulted in inducing 26 states to adopt compulsory sterilization laws for persons considered unfit for reproduction. Margaret Sanger, the protagonist of fertility control, advocated a program of compulsory sterilization for imbeciles, illiterates, criminals, epileptics, the mentally retarded, prostitutes, and drug traffickers. 7686 sterilizations were performed in North Carolina, of which about 5000 were performed on Blacks to prevent the reproduction of mentally retarded persons. It was only in 1974 that guidelines were drawn up to prevent sterilization abuses. Under federal programs 100,000-200,000 persons were sterilized in 1972, and 35% of Puerto Rican women of reproductive age underwent sterilization. In Brazil 44% of the population of 147 million is Black. In 1940 the White population was the majority, but by 1980 a steady increase of the mulatto population had occurred. From 1965 on the White population began to decrease both because of oral contraceptive use and intermarriage. The fertility rate of the mulatto population was 4.1% in 1980 and 2.3% in 1990, less than the 2.4% rate of whites. The total fertility rate (TFR) in Brazil was 3.5 children per woman in 1986, which dropped to 2.5 in 1991. In the northeast, where the majority of the population is Black, the TFR was 3.7 in 1991 vs. 7.5 in 1970. Although in Brazil racial intolerance is not acceptable, there is still inequality of opportunity for Blacks. In

    2013-05-01

    Ground-truth (GT) events, accurately located with a precision of 5 km (GT5 event) and associated travel times to regional stations are important in developing precise velocity models. The low Brazilian seismicity, with only three continental earthquakes of magnitude five in the last three decades, and the low number of seismic stations explain the difficulty to detect events at regional distances. In the world maps of GT events, Brazil appears almost empty. In Stable Continental Interiors, like Brazil, it is difficult to find an event fulfilling all the GT5 prerequisites, particularly in respect with the number of picked phases and azimuthal gaps. Recently PTS-CTBTO has organized meeting and workshops to encourage seismologists from South and Central America to cooperate with the work of identifying GT5 events in these countries, with a goal of developing a 3-dimentional velocity model for this part of the globe not covered yet like Europe and North America. As a result we studied a recent magnitude 5 event in Central Brazil detected by few regional stations. Aftershock studies with local stations, showed a fault 5 km long. Taking the mainshock epicenter as the center of fault the maximum error would be minimal, 2.5 km, assuming the events were located with zero uncertainty. The parameters depth and origin time source were precisely determined using correlations between waveforms of six events and stations corrections. The event magnitudes range from 3.5 to 5.0 (mainshock, taken as reference event) recorded by regional and local stations. Events recorded at local and regional stations were used to determine the regional station corrections. These events were located only with data from local stations, assigning to the regional stations P and S phases zero weight in order to determine residuals for each regional stations used. The stations corrections were taken as the average of the residuals at each station. Precise pickings of P and S phases for the mainshock

  7. Favourable environments for uranium occurences in Brazil

    International Nuclear Information System (INIS)

    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)

  8. On high interest rates in Brazil

    Directory of Open Access Journals (Sweden)

    Francisco Lafaiete Lopes

    2014-03-01

    Full Text Available This article examines the question of why interest rates are so high in Brazil as compared to the international average. It looks at theoretical arguments based on excessive government deficits, structural lack of private savings, inflation bias, excessive investment demand and fear of floating. An informal look at the evidence does not strongly corroborate any of these arguments. Hence a wise central bank should consider "testing" the market to make sure it is not dealing with an extreme equilibrium configuration or a long standing disequilibrium.

    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

  14. The changing face of autism in Brazil.

    Rios, Clarice; Costa Andrada, Barbara

    2015-06-01

    At the end of 2012, after intensive lobbying by parent activist associations, a federal law recognized autism as a "disability for all legal purposes" in Brazil. Defining autism as a disability was more than a change of legal status to guarantee social benefits. It was also a political maneuver, orchestrated by parent associations, aimed to take the responsibility for treatment away from the public mental health network of services. This article examines the controversies that have set parent associations in direct antagonism with mental health professionals in the public health system. We draw from ethnographic data and theoretical discussions in the field of disability studies to situate these controversies within the context of a larger debate on the relationship between health, rights, and citizenship. We found similarities between the ethical and political goals of parent activists and mental health professionals in Brazil, but we argue that the main cause of dissent is the role that each of these social actors assigns to identity politics in their clinical and political projects.

    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. PMID:24212689

    2015-10-01

    The use of blood products as essential medicines and the recognition of the high risk associated with blood transfusions require governments to take regulatory action with a focus on quality and safety. In this scenario, regulatory agencies play an essential role in socially advancing the guarantee that blood components will be produced according to current operating rules. Thus, in the effort to manage sanitary risks involved in the processing and use of blood, the Brazilian regulatory model, based on the construction of a national blood policy overseen by the State, has undergone conceptual improvement and review of the tools employed to achieve its goals. With the inclusion of good manufacturing practices as part of the Brazilian norms, as recommended by the World Health Organization, the country has moved forward in its view of blood facilities as manufacturing centers producing blood-derived biologics for therapeutic applications. It has also strengthened the need to develop safety mechanisms for blood donors and recipients. The development of a State-coordinated national blood policy and the institution of a national surveillance system with legitimate power of inspection are essential elements used in Brazil to guarantee the amount, quality, safety, and timeliness of blood supply to the population. The present article aims to discuss the present context of the blood regulatory model in Brazil so as to identify the challenges for improvement of this model. PMID:26758225

    Bullying has been the subject of worldwide study for over four decades and is widely reported by social media. Despite this, the issue is a relatively new area of research in Brazil. This study analyzes academic literature addressing bullying produced in Brazil focusing on aspects that characterize this issue as a subtype of violence: gender differences, factors associated with bullying, consequences, and possible intervention and prevention approaches. The guiding question of this study was: what have Brazilian researchers produced regarding bullying among adolescents? The results show that over half of the studies used quantitative approaches, principally cross-sectional methods and questionnaires, and focused on determining the prevalence of and factors associated with bullying. The findings showed a high prevalence of bullying among Brazilian adolescents, an association between risk behavior and bullying, serious consequences for the mental health of young people, lack of awareness and understanding among adolescents about bullying and its consequences, and a lack of strategies to manage this type of aggression. There is a need for intervention studies, prevention and restorative practices that involve the community and can be applied to everyday life at school. PMID:26602728

    Gnathostomiasis is a parasitic disease caused by nematode larvae ingestion of 15 known species of the genus Gnathostoma (one of the Gnathostomatidae family members). This parasite uses freshwater fish as a host and can infect - through the consumption of raw fish or their viscera - other animals such as dogs, cats, chickens, pigs, and humans. This parasitic disease, with humans acting as hosts, has been known since 1945 (India), and ocular complications have been known since 2004 (intravitreal; also described in India). Latin American countries, especially Mexico and Peru, have reported cases of the disease since 1970. The first dermatological case was reported in Brazil in 2009 (the individual had acquired the disease in Peru). This article describes the first reported ophthalmic case of the disease in Brazil and refers to a male patient, 30 years old, living in the municipality of Juruá, Amazonas State. The disease evolved within 30 days through a fistulized tumor in the inner corner of the lower eyelid. Following excision, the anatomical and histopathological examination revealed the presence of a different parasite species from other previously known genera. PMID:27239465

    No energy, whether renewable, clean or known by any other name can possibly be relied upon as the only solution for ensuring a supply of electricity compatible with a nation's economic and social development. Brazilian consumption and installed capacity of electric power generation per capita indices are still inadequate and below the world average-this crucial fact must be considered. It obliges Brazil to take the most advantage of all resources available to increase its electricity generation capacity as rapidly as possible, thereby enabling consumption to reach levels compatible with the quality of life the Brazilian population aspires to. The planning of a country's electric system requires efficient management of a diversified portfolio of energy sources. In Brazil, hydroelectricity will continue for many years yet to be the main component of its portfolio of electric power generation sources, but it must be supplemented by thermal sources- uranium, coal, biomass, natural gas, and oil by-products derived from petroleum-in this order of importance, keeping in mind aspects related to local availability, cost, environmental impacts, and use in other applications.

    OBJECTIVE To review the frequency of and factors associated with fetal death in the Brazilian scientific literature. METHODS A systematic review of Brazilian studies on fetal deaths published between 2003 and 2013 was conducted. In total, 27 studies were analyzed; of these, 4 studies addressed the quality of data, 12 were descriptive studies, and 11 studies evaluated the factors associated with fetal death. The databases searched were PubMed and Lilacs, and data extraction and synthesis were independently performed by two or more examiners. RESULTS The level of completeness of fetal death certificates was deficient, both in the completion of variables, particularly sociodemographic variables, and in defining the underlying causes of death. Fetal deaths have decreased in Brazil; however, inequalities persist. Analysis of the causes of death indicated maternal morbidities that could be prevented and treated. The main factors associated with fetal deaths were absent or inadequate prenatal care, low education level, maternal morbidity, and adverse reproductive history. CONCLUSIONS Prenatal care should prioritize women that are most vulnerable (considering their social environment or their reproductive history and morbidities) with the aim of decreasing the fetal mortality rate in Brazil. Adequate completion of death certificates and investment in the committees that investigate fetal and infant deaths are necessary. PMID:25902565

  1. Dynamics of Sheep Production in Brazil

    2013-07-01

    Full Text Available Sheep production is present on all continents and has been practiced in Brazil since the colonization. In this study, the multitemporal dynamics of sheep production in Brazil is examined using official government data (Brazilian Institute for Geography and Statistics-IBGE from 1976 to 2010. Maps of flock growth rates and growth acceleration maps by municipality were elaborated. The Southern states are seen to show a reduction in production mainly due to the wool crisis in the 1970s and 80s. The Northeast is seen to be important for meat production. More recently, centerwest and northern states have shown an increase in growth rates but this is still incipient. The maps of growth, acceleration and midpoint for sheep production showed a noticeable return to an increase in production in the South in recent years. The midpoint of production flow was in the northeast direction, which has stagnated. There was great dynamics in sheep production over the whole Brazilian territory, which affected supply chains due to the expansion of domestic and foreign markets. Areas with higher fluctuations in production are more vulnerable in terms of investment policies.

    Apart from an early case report from China (13th century), the first observations on insects and other arthropods as forensic indicators were documented in Germany and France during mass exhumations in the 1880s by Reinhard, who is considered a co-founder of the discipline. After the French publication of Mégnin's popular book on the applied aspects of forensic entomology, the concept quickly spread to Canada and United States. At that time, researchers recognized that the lack of systematic observations of insects of forensic importance jeopardized their use as indicators of postmortem interval. General advances in insect taxonomy and ecology helped to fill this gap over the following decades. After World Wars, few forensic entomology cases were reported in the scientific literature. From 1960s to the 1980s, Leclercq and Nuorteva were primarily responsible for maintaining the method in Central Europe, reporting isolated cases. Since then, basic research in the USA, Russia and Canada opened the way to the routine use of Entomology in forensic investigations. Identifications of insects associated with human cadavers are relatively few in the literature of the Neotropical region and have received little attention in Brazil. This article brings an overview of historic developments in this field, the recent studies and the main problems and challenges in South America and mainly in Brazil. PMID:17352063

  3. Status of food irradiation in Brazil

    International Nuclear Information System (INIS)

    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.)

  4. Overview of flue gas treatment in Brazil

    International Nuclear Information System (INIS)

    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 SO2 and NOX from flue gases by single process, requiring no additional wastewater treatment system and can produce useful nitrogen fertilizer consisting of ammonium sulfate (NH4)2SO4 and ammonium nitrate NH4NO3 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.

    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.

  7. Biomass energy potential in Brazil. Country study

    International Nuclear Information System (INIS)

    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.

  8. Seismic risk map for Southeastern Brazil

    International Nuclear Information System (INIS)

    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.

    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.

    Full Text Available Coccidioidomycosis is an endemic infection with a relatively limited geographic distribution: Mexico, Guatemala, Honduras, Colombia, Venezuela, Bolivia, Paraguai, 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. Case report: 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° C and 30° C showed growth of white and cottony aerial micelium. 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

  13. The monazite processing legacy in Brazil

    International Nuclear Information System (INIS)

    Full text: Naturally occurring radioactive material (NORM) is widespread throughout the earth's environment. During mineral processing, the radioactive isotope levels contained can be altered or concentrated to a point that it can be a matter of concern regarding to public and workers' radiation exposure. Until recently these industries were not taken into consideration in nuclear regulations. The monazite industry is one of the industries that can produce radioactive residuals and environmental impacts. The chemical processing of monazite aiming the production of lanthanide chlorides and tri-sodium phosphate was started in Brazil at Santo Amaro mill (USAM), in 1949, aiming the production of earth rare chlorides. The production stopped in 1992. As a consequence of forty-three years of chemical processing, different types of radioactive residues were produced. Throughout the years a great quantity of these residues was generated, being stored at the moment in silos, drums of rubber in storage buildings and sealed in trenches dispersed to different parts of the country. As until 80s decade there were not radiological protection rules concerning to the storage and transportation of these kinds of residues, mineral radioactive residues were used as landfills and the residues of the chemical process contaminated floors and buildings. The decommissioning process and cleaning of old plants has generated tons of wastes that have joined those previously produced. This work reports and discusses the cycle of monazite in Brazil and its consequences in terms of site remediation and quantities of wastes and residues generated and stored. (orig.)

  14. Assistance to Brazil, Pakistan and Thailand

    International Nuclear Information System (INIS)

    IAEA's technical assistance programme for the current year includes aid to atomic energy projects in Brazil, Pakistan and Thailand. It is proposed to establish a radiation measurement service in Brazil where radioactive isotopes are finding increasing use in medicine, industry and research. The assistance to be provided by IAEA will consist of equipment for the proposed service, and experts who would give courses in their respective specializations and co-operate in the testing of equipment, initiation of measurements and organization of working plans. The Agency is putting three specialists at the disposal of the Pakistan Atomic Energy Commission: one of them an expert on research reactors, another on radioisotopes and irradiation by gamma rays, and the third on health physics. The Pakistan Government has decided to set up an Institute of Nuclear Research and Reactor Technology, where it is planned to install a reactor with a power level of 1 MW to be increased later to 5 MW. The main purposes of the reactor project will be: training on reactor operation and reactor physics; training and research in neutron physics; research on radiation physics and nuclear chemistry; production of radioisotopes; biological research on the effects of radiation; radiation protection and shielding, and research in nuclear engineering and metallurgy. Under a third project, IAEA has sent an expert to Thailand to assist in the development of the medical applications of radioisotopes, particularly in diagnosis and clinical research

  15. Chemical correlations in Caetite (BA) region, Brazil

    International Nuclear Information System (INIS)

    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 238U 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)

    2009-04-01

    A recent review on South American phenology research has shown an increase in phenology papers over the last two decades, especially in this new 21st century. Nevertheless, there is a lack of long term data sets or monitoring systems, or of papers addressing plant phenology and global warming. The IPCC AR4 report from 2007 has offered indisputable evidence of regional to global-scale change in seasonality, but it is supported by plant and animal phenological data from North Hemisphere and temperate species. Information from tropical regions in general and South America in particular are sparse or lacking. Here I summarize the recent outcomes of our ongoing tropical phenology research in Brazil and its potential contribution to integrate fields and understand the effects of global warming within the tropics. The Phenology Laboratory (UNESP) is located at Rio Claro, São Paulo State, Southeastern Brazil. We are looking for trends and shifts on tropical vegetation phenology, and are exploring different methods for collecting and analyzing phenology data. The phenological studies are developed in collaboration with graduate and undergraduate students, post-docs and researchers from Brazil and around the world. We established three long term monitoring programs on Southeastern Brazil from 2000 onwards: trees from an urban garden, semideciduous forest trees, and savanna cerrado woody vegetation, all based on direct weekly to monthly observation of marked plants. We have collected some discontinuous data from Atlantic rain forest trees ranging from 5 to 8 years long. I collaborate with the longest tropical wet forest phenology monitoring system in Central Amazon, and with another long term monitoring system on semi deciduous forest from South Brazil. All research programs aim, in the long run, to monitor and detect shifts on tropical plant phenology related to climatic changes. Our first preliminary findings suggest that: (i) flowering and leafing are more affected by

    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

  20. The new role of Brazil in energy geopolitics

    International Nuclear Information System (INIS)

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

    2013-06-01

    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.

    Tenancy has been a means for labor to advance their socio-economic condition in agriculture yet in Brazil and Latin America, tenancy rates are low compared to the U.S. and the OECD countries. We test for the importance of insecure property rights in Brazil on the reluctance of landowners to rent because of a fear of expropriation arising from land reform. Since 1964, the Land Statute in Brazil has targeted rental lands for redistribution. The expropriation of farms, resulting from land confli...

    The incidence of dengue fever and dengue hemorrhagic fever in Brazil experienced a significant increase since the emergence of dengue virus type-3 (DENV-3) at the early 2000s. Despite the major public health concerns, there have been very few studies of the molecular epidemiology and time-scale of this DENV lineage in Brazil. In this study, we investigated the origin and dispersion dynamics of DENV-3 genotype III in Brazil by examining a large number (n = 107) of E gene sequences sampled betw...

  5. Biomass gasification: A demonstration in Brazil

    International Nuclear Information System (INIS)

    Biomass Integrated Gasification-Gas Turbine (BIG-GT) cycles offer considerable opportunities for improved efficiency in biomass power systems. As a result of international collaboration, a full-scale plant in Brazil will be the first commercial scale demonstration plant to utilise this system. The project, if successful, will lead to the commercial development of highly efficient, relatively easily installed biomass energy plants. The global implications could be significant, with biomass possibly contributing to power supplies in a scale similar to nuclear and hydro by the mid 21st century. It could provide a basis for rural development and employment in developing countries, and utilization of excess crop land in the industrial world

  6. Comments on human eurytremiasis in Brazil

    Science.gov (United States)

    Pinto, Hudson Alves; de Melo, Alan Lane

    2016-01-01

    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.

  7. Brazil's Petrobras chops 1992 capital budget

    International Nuclear Information System (INIS)

    This paper reports that Brazil's state owned Petroleos Brasileiro SA has slashed its 1992 capital budget by more than half for lack of adequate cash flow. Petrobras Pres. Benedicto Moreira last week disclosed the cut, to $1.4 billion from $2.9 billion earmarked earlier, citing cash flow problems stemming from heavy subsidies for domestic products. Petrobras Association of Engineers (Aepet) disputes the latest amount, claiming without elaboration the state company actually is cutting the current budget to $1 billion. At either level, the severe budget cut bodes ill for Petrobras plans to boost domestic production by a net 300,000 b/d to 1 million b/d by 1995, an ambitious program that calls for outlays of $18 billion

  8. Environmental and Social Accounting for Brazil

    International Nuclear Information System (INIS)

    An environmentally extended Social Accounting Matrix (SAM) has been constructed for Brazil for the first time. We review in detail previous studies in this field, describe the construction, structure and data sources of the Brazilian SAM, and demonstrate the effect of system closure. Examining a range of type-I and type-II multipliers, we show that incomes generated by final consumption are highly skewed towards rich households, but energy requirements and carbon emissions are higher for the consumption of the poor. A significant negative correlation exists between employment and income on one hand, and energy requirements and carbon emissions on the other, while a significant positive correlation exists between imports, and energy and carbon. These correlations demonstrate that there is scope for policies that pursue imports substitution and reduce energy consumption and carbon emissions whilst increasing employment and income

  9. Democratization and Transitional Justice in Brazil

    2016-05-01

    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.

    Paraná is a state at South of Brazil with a population of 11 million people. There are two planetarium and two fixed observatories devoted to Astronomy outreach. The great majority of population have no access to information and knowledge of astronomy discoveries. Another problem is the teaching formation of astronomy studies. In this work we relate an initiative that started at the International Year of Astronomy in 2009 that involved Universities and amateur groups that is still in place. After several grants from the Brazilian National Council for Scientific and Technological Development and Araucária Foundation we were able to reach more than 100.000 people with a mobile planetarium and night astronomic observations. We also providde one-week classes to more than 1.000 teachers in several cities of the state.

    2009-07-01

    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.

    This thesis aims to study alternatives to biodiesel industry in Brazil, for 2030, taking in account the sustainability dimensions, namely economic, environmental, ecological, social, national and international politics, territorial, cultural, and technological, through the development of scenarios...... for agriculture and pasture. Thus, a simulation, using linear programming models, was made in order to verify the alternatives of feedstock to produce biodiesel. It was observed that it is possible to decentralize the market, reduce land use, and regionalize production, making better use of the availability...... to identify the driving forces to develop the scenario storylines. This proposition was tested in an in-depth interview with the biodiesel market stakeholders. Based on the findings of the two approaches, the simulations and the interviews, it was possible to obtain future alternatives, where the biodiesel...

  13. Status of fast reactor activities in Brazil

    International Nuclear Information System (INIS)

    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)

  14. Physical protection philosophy and techniques in Brazil

    International Nuclear Information System (INIS)

    The authors discuss three fundamental features of nuclear activities that users of nuclear energy and materials must take into account when considering the welfare of the population: Safeguards, Security, and Safety. These features define three different systems devised to assure that nuclear facilities and materials are properly, securely, and safely handled and that no radioactive material will ever be removed or dispersed. This paper describes briefly the Safeguards System as it is understood in Brazil, introduces the Physical Protection System, and shows their common features which might be integrated to form a broader system. Safeguards are defined as an array of measures and procedures designed to detect the diversion of nuclear material. The Safeguard System consists of three basic measures, accountability, containment, and surveillance

    This presentation shows a summary of UV index measurements performed in the last years in Southeastern (SE) and Northeastern (NE) Brazilian regions. Brazil has an area of 8.5 million km2 distributed between latitudes 5˚ N and 35˚ S and longitudes 5˚ W and 75˚ W. SE is the most important economic pole of South America and the NE coast is an important tourist region. This large area has a great diversity of climatic, atmospheric and geographical conditions in addition to very diverse social and cultural habits. Non-melanoma skin cancer (NMSC) is an epidemiological health problem with more than 120,000 new cases each year. The most of these cases are found in the South and Southeast regions, with about 70 new NMSC per 100,000 inhabitants. Solar Light UV501 biometers are installed in the SE cities of São Paulo (23.6˚ S, 46.7˚ W, 865 m ASL), Itajubá/Minas Gerais (22.4˚ S; 45.5˚ W, 846 m ASL) and the NE city of Ilhéus/Bahia (14.8˚ S; 39.3˚ W; 54 m ASL). First measurements began in 2005 in São Paulo city, while Itajubá and Ilhéus have regular measurements from the beginning of 2008. Other studies related to the UV radiation modeling and interactions with atmosphere components, as ozone, aerosols and clouds, have also been performed. For example: a) UVI modelling calculations performed by a multiple-scattering spectral models; b) studies on the aerosol radiative properties based on satellite (MODIS/Terra-Aqua) and ground-based (Aeronet) observation; c) ozone content variability from satellite (OMI/Aura) and ground-based (Microtops ozonometer) measurements; d) behavioral profile of the population, as regarding habits of solar exposure and sun protection measures. Results show that more than 75% of the measurements conducted in the summer (outside noon) can be classified as upper than high UVI according to World Health Organization (WHO) recommended categories: Low (UVI < 2), Medium (3 ? UVI < 6), High (6 ? UVI < 8), Very High (8 ? UVI

    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.

    Characterization of canine coronavirus (CCoV) strains currently in circulation is essential for understanding viral evolution. The aim of this study was to determine the presence of pantropic CCoV type IIa in tissue samples from five puppies that died in Southern Brazil as a result of severe gastroenteritis. Reverse-transcriptase PCR was used to generate amplicons for sequence analysis. Phylogenetic analysis of the CCoV-IIa strains indicated that they were similar to those found in other countries, suggesting a common ancestor of these Brazilian isolates. This is the first report of pantropic CCoV-II in puppies from Latin America and our findings highlight that CCoV should be included as a differential diagnosis when dogs present with clinical signs and lesions typically seen with canine parvovirus infection.

    The injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in the victim. The cnidarians (jellyfishes, especially cubomedusas and Portuguese-Man-of-War) caused nearly 25% of 236 accidents by marine animals, while sea urchins were responsible for about 50% and catfish, stingrays and scorpionfish nearly 25%). In freshwater, stingrays and catfish cause injuries with a very similar mechanism to the poisoning and the effects of the toxins of marine species. In a series of about 200 injuries observed among freshwater fishermen, nearly 40% were caused by freshwater catfish, 5% freshwater stingrays and 55% by traumatogenic fish, such as piranhas and traíras. The author presents the aquatic animals that cause injuries to humans in Brazil, the clinical aspects of the envenoming and the first measures for the control of the severe pain observed mainly in the accidents caused by cnidarians and venomous fishes.

    Zika virus (ZIKV) is a flavivirus that is responsible for the current epidemic in Brazil and the Americas. ZIKV has been causally associated with fetal microcephaly, intrauterine growth restriction, and other birth defects in both humans and mice. The rapid development of a safe and effective ZIKV vaccine is a global health priority, but very little is currently known about ZIKV immunology and mechanisms of immune protection. Here we show that a single immunization with a plasmid DNA vaccine or a purified inactivated virus vaccine provides complete protection in susceptible mice against challenge with a strain of ZIKV involved in the outbreak in northeast Brazil. This ZIKV strain has recently been shown to cross the placenta and to induce fetal microcephaly and other congenital malformations in mice. We produced DNA vaccines expressing ZIKV pre-membrane and envelope (prM-Env), as well as a series of deletion mutants. The prM-Env DNA vaccine, but not the deletion mutants, afforded complete protection against ZIKV, as measured by absence of detectable viraemia following challenge, and protective efficacy correlated with Env-specific antibody titers. Adoptive transfer of purified IgG from vaccinated mice conferred passive protection, and depletion of CD4 and CD8 T lymphocytes in vaccinated mice did not abrogate this protection. These data demonstrate that protection against ZIKV challenge can be achieved by single-shot subunit and inactivated virus vaccines in mice and that Env-specific antibody titers represent key immunologic correlates of protection. Our findings suggest that the development of a ZIKV vaccine for humans is likely to be achievable. PMID:27355570

  20. Ethanol demand in Brazil: Regional approach

    International Nuclear Information System (INIS)

    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.

  1. Mucorales from the semiarid of Pernambuco, Brazil

    2013-01-01

    Full Text Available Nineteen taxa of Mucorales, belonging to Absidi, Apophysomyces, Cunninghamella, Fennellomyces, Lichtheimi, 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 ºC for 72 h of alternating dark and light periods. Absidia cylindrospora presented the highest amount of CFU/g of soil, followed by L. hyalospor, 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.

  2. Niobium (columbium) and tantalum resources of Brazil

    White, Max Gregg

    1975-01-01

    Most of the niobium resources of Brazil occur as pyrochlore in carbonatites within syenitic intrusives of Late Cretaceous to early Tertiary age in western Minas Gerais and southeastern Goils. Minor amounts of it are produced together with tantalum from columbite-tantalite concentrates from pegmatites and placers adjacent to them, in the Sao Joao del Rei district in south-central Minas Gerais. All the niobium and tantalum produced in Brazil is exported. The only pyrochlore mined is from the Barreiro carbonatite deposit near Araxa in Minas Gerais where concentrates and ferroniobium are produced. Exploration work for pyrochlore and other mineral resources are being undertaken on other carbonatites, particularly at Catalao I in southeast Goias and at Tapira and Serra Negra in western Minas Gerais. Annual production and export from the Barreiro deposit are about 8,000 metric tons of pyrochlore concentrate containing about 60 percent Nb205 and about 2,700 metric tons of ferroniobium with 63 percent Nb2O5. The annual production capacity of the Barreiro plant is 18,000 tons of concentrate and 4,000 tons of ferroniobium.

    Misoprostol, a prostaglandin E1 analogue indicated for ulcer treatment, has been widely used as an abortifacient by women in Brazil, where abortion is legal only in cases of rape or incest, or to save the woman's life. Because misoprostol is an inefficient abortifacient, many women who use it have incomplete abortions and need uterine evacuation. We reviewed the records of women admitted to the main obstetric hospital of Fortaleza, capital of Ceará state, Brazil, between January, 1990, and July, 1992, for uterine evacuation after induced abortion. The number of incomplete abortions induced by misoprostol increased substantially during the first half of 1990, and declined thereafter. Of the 593 cases in 1991, 75% were related to misoprostol, 10% to the use of other specified drugs, and 6% to unspecified drugs. For the remaining 9% the procedure used was not recorded; these included 3% in whom abortion had been induced by a clandestine abortionist. The number of uterine evacuations per month fell from 89 in August, 1990, to 62 in July, 1991, when sales of misoprostol in Ceará state were suspended. The fall continued after the sale of misoprostol ceased, to about 20 cases in December, 1991; numbers remained around this level until June, 1992, sustained by clandestine sales. The lack of access to contraception is the main reason for the large numbers of unplanned pregnancies and is a major public health issue for Brazilian women. The prohibition of abortion creates a void in which misuse of medicines is one extra complication, mainly because of the poor control of drug marketing. PMID:8098403

  10. Genetic Improvement of Crops by Mutation Techniques in Brazil

    International Nuclear Information System (INIS)

    Agriculture in Brazil has a prominent position in the country's economy due to its large spread under diverse but suitable climatic conditions which are indispensable for higher performance of many crops. Therefore, constant efforts in plant breeding by traditional methods have led Brazil to be internationally recognized as a tropical agricultural country. Spontaneous mutations constitute the source of genetic variability and have been long utilized by breeders. In Brazil, various cultivars of seed propagated, as well as vegetatively propagated plants, were obtained from spontaneous mutation, such as cultivar 'Carioca' (Phaseolus vulgaris L.) and cultivar 'Bahianinha' (Citrus sinensis L.). After introduction of mutation induction in Brazil, several breeding programmes using mutagens, such as nuclear radiation, alkylating and non-alkylating chemical compounds, have been carried out to increase crop production. As will be reported, various mutants were selected or are in the process of selection. (author)

  11. Nuclear proliferation. I. Atoms for Brazil, dangers for all

    International Nuclear Information System (INIS)

    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

  12. Privatization of Brazil's petroleum sector on track despite scandal

    International Nuclear Information System (INIS)

    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

  13. The implementation of PET technology in Brazil

    International Nuclear Information System (INIS)

    According to the Brazilian Geography and Statistics Institute, Brazil has an estimated population of 188 million inhabitants spread over 8,500,000 km2: The distribution of resident population in major regions of Brazil is shown: North Region - 7.6%; Northeast Region - 28.1%; Southeast Region - 42.6%; South Region - 14.8%; Central West Region - 6.9%. Nuclear Medicine is growing fast in Brazil and this has resulted in an increasing demand for radioisotopes and radiopharmaceuticals. Positron emission tomography (PET), which is a non-invasive molecular imaging procedure, is one of the causes of this increase. PET detects changes in metabolic activities, which may take place before any detectable change in anatomical structure occurs. PET is used to help diagnose and to plan and assess the treatment of cancer, heart disease, and brain disorders. Taking into account all these advantages, it was decided to start the production of PET radiopharmaceuticals at IPEN - Energy and Nuclear Research Institute of CNEN - the Brazilian National Nuclear Energy Commission, located in the city of Sao Paulo, the largest city in Brazil. The production of FDG started in 1998. In 2003, a second FDG production unit was installed at IEN - Nuclear Engineering Institute of CNEN - in Rio de Janeiro, the second largest city in Brazil. Both have much experience in radioisotope and radiopharmaceutical production, and both centres have had cyclotrons for a long time. It is interesting that the production of FDG has increased more than a factor of 17 since 2000 in Brazil. One of the greatest advantages of PET radiopharmaceuticals is due to their short lives. On the other hand, this is also a problem because it means that the production centre needs to be located not too far from the place where it will be used. This can limit the population access to PET technology. Taking into account this scenario and considering that short-lived radioisotope production was a State monopoly until 2006, the

    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.

    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

  5. NORM in Brazil: a general overview

    International Nuclear Information System (INIS)

    Full text: There are many industries using NORM in the world today and they have been growing in a large scale. This growth has drawn the international radiation protection community's attention. They have been discussing the importance of being aware of the existence or not of radiological risks associated with the exploration of ores containing both uranium and thorium, as well as, the treatment of these manufactured products. This fact led to the elaboration of TECDOC's, documents, Safety Reports Series produced by IAEA, and the elaboration of norms, normative instructions and regulatory guides, for the regulatory bodies organisms of the other countries. At this point, some radiological occupational risks have been identified in the industries pointed out below: a) Extraction of rare earth elements; b) Production and use thorium and its compounds; c)Production of niobium and ferro-niobium; d) Mining of ores other than uranium ore; e) Production of oil and gas; f) Manufacture of titanium dioxide pigments; g) Phosphate industry; h) The zircon and zirconia industries; i) Production of tin, copper, aluminum, zinc, lead, and iron and steel; j) Combustion of coal and; k) Water treatment. In Brazil the evaluation of the radiological occupational risks associated with the NORM industries has been done without a centralized coordination, resulting in diversified, redundant and discontinued actions. The necessity of a planned evaluation is related to the growing numbers of the Brazilian NORM industry. Brazil owns reserves evaluated in 21 billion tons of the minerals mentioned, a total production of 260 million tons of ores and 200 million tons of these treated ores production. Therefore, this work has as objectives: 1) To consolidate information of previous projects, to quantify and to identify the mining company and treatment and to order them in groups; 2) To quantify the number of workers involved in the production and to identify the potential risk of process

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

    Tuberculosis in cattle is a chronic infectious-contagious disease characterized by the development of nodular lesions (granulomas) in mainly the lungs and regional lymph nodes. It is caused by Mycobacterium tuberculosis complex, an acid-fast bacillus (AFB). Tuberculosis in the central nervous system is a rare condition in cattle. Herein, we describe the clinical and pathological findings of six neurotuberculosis cases in cattle diagnosed in Southern Brazil. The average age of the cattle affected was 12 months, and they varied in breed and sex. The clinical history ranged from 5 to 30 days and was characterized by motor incoordination, opisthotonus, blindness, and progression to recumbency. The cattle were euthanized, and grossly, the leptomeninges at the basilar brain showed marked and diffuse expansion, with nodular yellowish lesions ranging in size. On microscopic examination, there were multifocal granulomas located mainly in the meninges, though sometimes extending to adjacent neuropil or existing as isolated granulomas in neuropil. AFBs were observed in the cytoplasm of epithelioid macrophages and multinucleated giant cells through Ziehl-Neelsen histochemical staining and identified as Mycobacterium sp. through immunohistochemistry.

    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.

    2013-06-01

    In Brazil, overweight and obesity are increasing in all age and income groups. Currently, 7.3% of children under 5 years of age, 30% of children aged 5-9 and 20% of preadolescents aged 10-19 are overweight. In the primary health-care (PHC) environment, activities are carried out to monitor eating habits and nutrition, as well as to prevent unhealthy habits and promote healthy eating behaviors consistent with the dietary guidelines for Brazilian children. Comprehensive care is being provided to overweight individuals. The Brazilian Breastfeeding and Complementary Feeding Strategy was launched in 2009 to support health teams to counsel families about healthy feeding, focused on child health and obesity prevention. Within the school environment, the School Health Program offers activities that are developed by PHC teams together with education professionals to focus on assessing health conditions, prevention and health promotion. To improve the nutritional profile of processed foods, terms of cooperation have been signed with the food industry to reduce fat and sodium content. Food industry advertising and marketing to infants and young children are now regulated by the Brazilian Regulation for the Marketing of Foods to Infants and Young Children. PMID:27152158

    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.

  12. Why Brazil Needed a New Market Model

    International Nuclear Information System (INIS)

    This paper discusses how the issue of supply adequacy is treated in the Brazilian power market, analyzing lessons learned from past experiences and describing the solutions that are being implemented to reconcile competition in generation with an adequate supply. The primary goal of the initial reform process is Brazil was to ensure sufficient capacity and investment to serve reliably the country's growing economy. This work discusses the difficulties that were identified in its design in terms of supply reliability and the proposals and reforms introduced by two governments to correct them and to implement a design that reconciles competition in generation with a guarantee of adequate supply. It is shown that, due to the high influence of hydroelectric power, Brazilian spot prices do not provide clear economic signals for system expansion, which in turn make bilateral contracts a key element in the market design. Another difficulty that must be addressed is the need to provide adequate expansion in an environment where there is high uncertainty on demand growth levels

    Full Text Available In recent years elderly population is increasing substantially, about 650,000 per year, as well as the concept of unifamílies, ie, families consisting of a single person. In this paper, is proposed a reflection about health of elderly in Brazil, and the conditions of a chronic disease and its acute state - terminal. In the actual society, capitalist and capitalized, the individual is valued by his production, losing his value when acquires a disabling illnesses. There is a growing need for work, and each time there is less time and resources to manage the permanence of an elderly patient at home, or pay for a caregiver. This situation leads families to resort to hospitalization, which in turn makes the hospitals overcrowded with patients in this state, affecting both emergency care as the treatment of chronic patients. This fact occurs due to lack of hospital infrastructure, as well by the lack of units of the healthy system capable of providing palliative care. The questioning about the elderly who need palliative care, and reflection about the type of care dispended for this kind of patient, should be the focal point of professional's reflections, capable to lead him to a new way of thinking and, consequently, to inspire him to act in a new way.

  14. Brachiaria spp. poisoning of ruminants in Brazil

    2011-03-01

    Full Text Available Brachiaria species are the most important grasses for cattle production in Brazil. However, a limiting factor for the use of Brachiaria spp. is their toxicity. Most outbreaks of hepatogenous photosensitization are caused by B. decumbens; however B. brizantha, B. humidicola and B. ruziziensis can also cause poisoning. The poisoning affects cattle, sheep, goats and buffalo. Sheep are more susceptible than other animal species and the young are more susceptible than adults. There are differences in susceptibility among animals of the same species and it has been suggested that this resistance is genetic. Also has been suggested that buffalo and probably some sheep are resilient, i.e. when poisoned these animals have histologic lesions and high GGT serum concentrations, but do not show clinical signs. In general, saponin concentrations are higher in growing plants, but outbreaks occur all over the year, probably due to unexplained rise in saponin concentration in the plant. A clinical syndrome of progressive weight loss and death, without photosensitization, has been reported in cattle poisoned by B. decumbens. Main preventive measures are based on the selection of resistant or resilient animals and on the development of Brachiaria species or varieties with low saponin concentration.

    Full Text Available Based on two different samples, this article tests the performance of a number of Value Drivers commonly used for evaluating companies by finance practitioners, through simple regression models of cross-section type which estimate the parameters associated to each Value Driver, denominated Market Multiples. We are able to diagnose the behavior of several multiples in the period 1994-2004, with an outlook also on the particularities of the economic activities performed by the sample companies (and their impacts on the performance through a subsequent analysis with segregation of companies in the sample by sectors. Extrapolating simple multiples evaluation standards from analysts of the main financial institutions in Brazil, we find that adjusting the ratio formulation to allow for an intercept does not provide satisfactory results in terms of pricing errors reduction. Results found, in spite of evidencing certain relative and absolute superiority among the multiples, may not be generically representative, given samples limitation.

    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.

    Air temperature is one of the main weather variables influencing agriculture around the world. Its availability, however, is a concern, mainly in Brazil where the weather stations are more concentrated on the coastal regions of the country. Therefore, the present study had as an objective to develop models for estimating monthly and annual mean air temperature for the Brazilian territory using multiple regression and geographic information system techniques. Temperature data from 2,400 stations distributed across the Brazilian territory were used, 1,800 to develop the equations and 600 for validating them, as well as their geographical coordinates and altitude as independent variables for the models. A total of 39 models were developed, relating the dependent variables maximum, mean, and minimum air temperatures (monthly and annual) to the independent variables latitude, longitude, altitude, and their combinations. All regression models were statistically significant ( α ≤ 0.01). The monthly and annual temperature models presented determination coefficients between 0.54 and 0.96. We obtained an overall spatial correlation higher than 0.9 between the models proposed and the 16 major models already published for some Brazilian regions, considering a total of 3.67 × 108 pixels evaluated. Our national temperature models are recommended to predict air temperature in all Brazilian territories.

    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.

  1. Dental radiographic exposures in Recife - Brazil

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the operating conditions of x-ray equipment installed in dental clinics in Recife, Brazil, as well as to evaluate the implementation of radiation protection procedures. The results showed that 42% of the inspected units present field diameters out of the range of values recommended by either national or international radiation protection organizations. Non-invasive tests performed in the x-ray units indicated that the discrepancy between the preset time and the true irradiation time was higher than 10% in 69% of the cases. The discrepancy between the preset and the applied kilo voltage, on the other hand, was higher than 10% in 35% of the inspected units. The survey indicated that the majority of the clinics do not use either lead aprons or collars for patients and that films are processed manually, without using timers or thermometers. The test made to verify the adequacy of the film processing box showed that 75% of them had poor light filtration capacity. In view of the results obtained it is strongly recommended that a quality control program be implemented in dental radiological clinics in Recife (author)

  2. Radiation balance of soybeans grown in Brazil

    International Nuclear Information System (INIS)

    This paper describes an experimental study of the radiation balance over a growing soybean (Glycine max (L.) Merrill) crop at a tropical agricultural experimental station, Jaboticabal (22°15′S 48°18′W), São Paulo, Brazil. Incoming shortwave radiation, S, net radiation, R, and the shortwave reflection coefficient, α, were measured over this crop from November 1976 to April 1977, and net longwave radiation, L, was deduced from the radiation balance equation. Hourly variation of the radiation components, S, αS, R and L, are presented for 4 nearly clear sky-days during the different growing crop periods. The diurnal variation of α is also presented for these 4 days. The mean daily albedo values for this vegetative surface were between 0.12 and 0.26, and inversely related to the vegetation height. A regression analysis of the radiation balance equation has been made, and the heating coefficient, β, and the longwave exchange coefficient, λ, obtained. The results of the study indicate that both β and λ are found to be descriptively helpful parameters in agricultural meteorology. Predicted regression equations for net radiation from shortwave radiation are presented for the different periods

    This paper describes the morphology of the equatorial electrojet (EEJ) along 45°W longitude in east Brazil, where the ground magnetic (dip) equator is associated with the largest declination in the world. Daily range of the horizontal field ( ), as expected, was largest at the station in the chain closest to the dip equator, Sao Luiz (inclination −0.25°S). was largest positive at Eusebio (inclination 9.34°S) and largest negative at Belem (inclination 7.06°N); both near the fringe of EEJ belt. at Sao Luiz during the daytime was unexpectedly large negative in-spite of a small dip and also located south of the dip equator where should be positive. Center of EEJ was found to be shifted southward of the dip equator by about 1° in latitude. During southern summer, started decreasing from 00 h and reached a minimum value in the afternoon, an abnormal feature not discussed for any station so far. The mid-day value of the direction of vector was 22°-24°W compared to the declination of 19°–21°W in the region.

  4. Nuclear Power in South-Central Brazil

    International Nuclear Information System (INIS)

    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''

  5. Radioactive characterization of phosphogypsum from Imbituba, Brazil

    International Nuclear Information System (INIS)

    This research aims to characterize the content of natural occurring radionuclides in phosphogypsum stacks at Imbituba, Santa Catarina state, Brazil. 226Ra, 228Ra, 40K, 238U and 232Th 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 226Ra 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 226Ra or 228Ra for the use of PG in agriculture as well as building materials. -- Highlights: • Concentration of 238U and 232Th in the PG stack 1 indicated an igneous origin. • The origin of the stack 2 cannot be determined due the similar values. • Concentration of 226Ra is below the limit recommended for use in agriculture. • Distribution of radionuclides through the stacks profile was very heterogeneous. • Low concentrations of 226Ra and 228Ra in soils of the areas surrounding the stacks

  6. NORM in Brazil - A General Overview

    International Nuclear Information System (INIS)

    There are many industries using NORM in the world today and they have been growing in a large scale. This growth has drawn the international community's attention. They have been discussing the importance of being aware of the existence or not of radiological risks associated with the exploration of ores containing both uranium and thorium, as well as, the treatment of these manufactured products. This fact led to the elaboration of TECDOC's, documents, Safety Reports Series produced by IAEA, and the elaboration of norms, normative instructions and regulatory guides, for the regulatory bodies organisms of the other countries. In Brazil the evaluation of the radiological occupational risks associated with the NORM industries has been accomplished without a centralized coordination doing with that there are diversified actions and discontinued actions. The necessity of a planned evaluation is related to the growing numbers of the Brazilian NORM industry. Therefore, this work has as objectives: 1. To consolidate information of previous projects, to quantify and to identify the mining company and treatment and to order them in groups; 2. To quantify the number of workers involved in the production and to identify the potential risk of process industrial areas; 3.: To evaluate the industrial processing areas through direct measurements: dose rate, surface contamination radon monitoring and air samples collection and smear samples.

The effective recording of vaccine data is a factor for the definition of its supply chain. This study investigated vaccine data recording relatively to data collected from vaccination rooms and data obtained from a government-developed Internet platform. Methods: The monthly recorded total number of diphtheria and tetanus toxoids and pertussis vaccine (alone or in combination with the Haemophilus influenzae type b conjugate vaccine doses administered in a medium-sized city of the Southeast region of Brazil was collected for the period January/2006 through December/2010 from two sources: City level (directly from vaccination rooms, the study "gold standard", and Federal level (from an Internet platform developed by the country government. 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 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 aim of this study was to investigate risk factors for ocular toxoplasmosis (OT) in patients who received medical attention at a public health service. Three hundred and forty-nine consecutive patients, treated in the Outpatient Eye Clinic of Hospital de Base, São José do Rio Preto, São Paulo state, Brazil, were enrolled in this study. After an eye examination, enzyme-linked immunosorbent assay (ELISA) was used to determine anti-Toxoplasma gondii antibodies. The results showed that 25.5% of the patients were seronegative and 74.5% were seropositive for IgG anti-T. gondii antibodies; of these 27.3% had OT and 72.7% had other ocular diseases (OOD). The presence of cats or dogs [odds ratio (OR) 2.22, 95% confidence interval (CI) 1.24-3.98, P = 0.009] and consumption of raw or undercooked meat (OR 1.77, 95% CI 1.05-2.98, P = 0.03) were associated with infection but not with the development of OT. Age (OT 48.2 ± 21.2 years vs. OOD: 69.5 ± 14.7 years, P dogs and cats as well as eating raw/undercooked meat increases the risk of infection, but is not associated with the development of OT.

  10. Occupational exposure to natural radiation in Brazil

    International Nuclear Information System (INIS)

    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)

  11. Bills to decriminalize abortion in Brazil.

    Science.gov (United States)

    1994-01-01

    The National Congress in Brazil is currently considering 9 abortion bills, 2 of which were introduced by women. In this interview, the women senators--Jandira Feghall of the Communist Party and Eva Blay of the Social Democrat Party--discuss the likely outcome of the abortion debate. Although the Roman Catholic Church has announced its intentions to oppose any liberalization of the abortion law, there are divisions within the Church as evidenced by the existence of groups such as Catholics for a Free Choice. Both senators agree that decriminalization of abortion will depend upon the societal response and an effort must be made to reach the many people who are confused and undecided about the issue. Although the present debate fits within the broader current debate on population policies, it has been the insistence of the feminist movement that put abortion reform on the agenda. Blay's bill calls for the legalization of abortion on demand until the 12th week of pregnancy and in cases of rape or risk to the woman's life after that point. A controversial aspect of Feghall's bill is the inclusion of maternal human immunodeficiency virus (HIV) infection as a condition for abortion. Feghall notes that this is an option rather than a requirement, but she will eliminate this condition if it engenders discrimination against HIV-infected women. PMID:12318722

  12. Making legal abortion accessible in Brazil.

    2002-05-01

    Abortion is legal in Brazil if it is the only means to save the woman's life or if the pregnancy is the result of rape. Although this has been the law for over 60 years, it has almost never been applied until recent years. In the past five years, the number of hospitals providing care to women victims of sexual violence has increased from 4 to 63, of which 40 are currently providing legal abortions. This paper describes a sensitization project and advocacy work carried out from within the obstetric and gynaecology establishment which has succeeded in motivating many key individuals and hospital staff to provide services for pregnancy termination in cases of rape. The dialogue between medical leaders and women's rights advocates and the emphasis on comprehensive care of women who have suffered sexual violence are key elements in the success of this initiative. The support of medical professionals, the organization and strength of the women's health and rights movement, the political support at federal, state and city government levels, including from the Federal Ministry of Health, and ongoing advocacy within the medical establishment have all been important elements in making the provision of services a reality.

  13. Brazil advances subsea technology in Marlim pilot

    Energy Technology Data Exchange (ETDEWEB)

    1993-03-29

    Petroleum Brasileiro SA has extended several water depth records for subsea technology during a pilot project in giant Marlim oil field in the Campos basin off Brazil. Petrobras finished the 10 well Marlim pilot last December. The field's pilot phase was intended to begin early production and enable Petrobras to gather more reservoir data. Ten satellite wells, including two prepilot wells, were completed during the Marlim pilot phase with guidelineless (GLL) wet christmas trees designed and fabricated by FMC Corp., Houston, and CBV Industrial Mechanic SA, Rio de Janeiro. The subsea wells are producing 52,000 b/d of oil and 21.19 MMCfd of gas in water depths of 1,847-2,562 ft. Marlim pilot well flow is routed to a permanent semisubmersible floating production system (FPS). Oil moves from the FPS to a monobuoy that offloads to a shuttle tanker. In addition to marking the first successful uses of purpose-built GLL wet trees, FMC said the Marlim pilot project allowed GLL subsea technology to evolve from conceptual status into a proven deepwater completion method. The paper describes the project.

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

    International Nuclear Information System (INIS)

    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.

  15. 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.

  16. Placing Brazil's heavy acid oils on international markets

    International Nuclear Information System (INIS)

    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.

    ABSTRACT OBJECTIVE To present national estimates regarding walking or cycling for commuting in Brazil and in 10 metropolitan regions. METHODS By using data from the Health section of 2008’s Pesquisa Nacional por Amostra de Domicílio (Brazil’s National Household Sample Survey), we estimated how often employed people walk or cycle to work, disaggregating our results by sex, age range, education level, household monthly income per capita, urban or rural address, metropolitan regions, and macro-regions in Brazil. Furthermore, we estimated the distribution of this same frequency according to quintiles of household monthly income per capita in each metropolitan region of the country. RESULTS A third of the employed men and women walk or cycle from home to work in Brazil. For both sexes, this share decreases as income and education levels rise, and it is higher among younger individuals, especially among those living in rural areas and in the Northeast region of the country. Depending on the metropolitan region, the practice of active transportation is two to five times more frequent among low-income individuals than among high-income individuals. CONCLUSIONS Walking or cycling to work in Brazil is most frequent among low-income individuals and the ones living in less economically developed areas. Active transportation evaluation in Brazil provides important information for public health and urban mobility policy-making PMID:27355465

    Humane education and the debate on alternatives to harmful animal use for training is a relatively recent issue in Brazil. While animal use in secondary education has been illegal since the late 1970s, animal use in higher science education is widespread. However, alternatives to animal experiments in research and testing have recently received attention from the Government, especially after the first legislation on animal experiments was passed, in 2008. This article proposes that higher science education should be based on a critical and humane approach. It outlines the recent establishment of the Brazilian Network for Humane Education (RedEH), as a result of the project, Mapping Animal Use for Undergraduate Education in Brazil, which was recognised by the 2014 Lush Prize. The network aims to create a platform to promote change in science education in Brazil, starting by quantitatively and qualitatively understanding animal use, developing new approaches adapted to the current needs in Brazil and Latin America, and communicating these initiatives nationally. This paper explores the trajectory of alternatives and replacement methods to harmful animal use in training and education, as well as the status of humane education in Brazil, from the point of view of educators and researchers engaged with the network.

    Better understanding the drivers of tropical deforestation is essential to research on global climate change and biodiversity loss, and would be particularly informative to ongoing international climate change negotiations. Geographically explicit maps of post-forest land cover can provide valuable information about the extent and spatial distribution of the major drivers of deforestation. Brazil is the country with the largest extent of tropical forest in the world and the one with the most tropical forest cover loss since the turn of this century. This fate of the forest study aims to determine which land covers have replaced forest cover in Brazil. Using a classification tree algorithm, we determined pasture and cropland extent in areas of forest cover loss in Brazil circa 2012. We used 30 m resolution Landsat data for the 2000-2013 time period as well as tree cover loss data from the Global Forest Change (GFC) maps published by Hansen et al. (2013). The GFC data was used to mask out areas not categorized as forest cover lost between 2000 and 2013. Additionally, the year of loss layer was used to disaggregate pasture and cropland extent by year. Our results comprehensively demonstrate the extent to which pasture is the dominant post-forest land cover in Brazil. More broadly, the product reveals spatiotemporal patterns of forest conversion to pasture and cropland in Brazil, which could lead to a better understanding of the underlying drivers of deforestation.

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

    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.

    The metastrongyloid nematode genus Angiostrongylus includes 18 species, two of which are relevant from a medical standpoint, Angiostrongylus costaricensis and Angiostrongylus cantonensis. The first was described from Costa Rica in 1971 and causes abdominal angiostrongyliasis in the Americas, including in Brazil. Angiostrongylus cantonensis, first described in 1935 from Canton, China, is the causative agent of eosinophilic meningitis. The natural definitive hosts are rodents, and molluscs are the intermediate hosts. Paratenic or carrier hosts include crabs, freshwater shrimp, amphibians, flatworms, and fish. Humans become infected accidentally by ingestion of intermediate or paratenic hosts and the parasite does not complete the life cycle as it does in rats. Worms in the brain cause eosinophilic meningitis. This zoonosis, widespread in Southeast Asia and the Pacific islands, has now been reported from other regions. In the Americas there are records from the United States, Cuba, Jamaica, Brazil, Ecuador, and Haiti. In Brazil seven human cases have been reported since 2007 from the southeastern and northeastern regions. Epidemiological studies found infected specimens of Rattus norvegicus and Rattus rattus as well as many species of molluscs, including the giant African land snail, Achatina fulica, from various regions of Brazil. The spread of angiostrongyliasis is currently a matter of concern in Brazil. PMID:23901376

    2011-03-01

    The record of dinosaur body-fossils in the Brazilian Mesozoic is restricted to the Triassic of Rio Grande do Sul and Cretaceous of various parts of the country. This includes 21 named species, two of which were regarded as nomina dubia, and 19 consensually assigned to Dinosauria. Additional eight supraspecific taxa have been identified based on fragmentary specimens and numerous dinosaur footprints known in Brazil. In fact, most Brazilian specimens related to dinosaurs are composed of isolated teeth and vertebrae. Despite the increase of fieldwork during the last decade, there are still no dinosaur body-fossils of Jurassic age and the evidence of ornithischians in Brazil is very limited. Dinosaur faunas from this country are generally correlated with those from other parts of Gondwana throughout the Mesozoic. During the Late Triassic, there is a close correspondence to Argentina and other south-Pangaea areas. Mid-Cretaceous faunas of northeastern Brazil resemble those of coeval deposits of North Africa and Argentina. Southern hemisphere spinosaurids are restricted to Africa and Brazil, whereas abelisaurids are still unknown in the Early Cretaceous of the latter. Late Cretaceous dinosaur assemblages of south-central Brazil are endemic only to genus or, more conspicuously, to species level, sharing closely related taxa with Argentina, Madagascar, Indo-Pakistan and, to a lesser degree, continental Africa.

    2001-01-01

    Full Text Available New records for nematode species recovered from elasmobranch fishes in Brazil are established and new systematical arrangements proposed. Parascarophis sphyrnae Campana-Rouget, 1955 from the spiral valve of Sphyrna zygaena is referred for the first time in South America as a new host record. Procamallanus (S. pereirai Annereaux, 1946, from the spiral valve of Raja castelnaui is reported parasitizing an elasmobranch host. Nematode larvae of the genera Anisakis, Contracaecum, Pseudoterranova and Raphidascaris are listed from the stomach and spiral valves of several hosts. Anisakidae larvae previously referred in Brazil in the genus Phocanema should be reallocated in Pseudoterranova. Nematodes of the genera Anisakis, Contracaecum, Pseudoterranova and Raphidascaris are reported for the first time parasitizing elasmobranchs in Brazil.

    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. PMID:24230936

    Zika virus is an emerging arbovirus transmitted by Aedes sp. mosquitoes like the Dengue and Chikungunya viruses. Zika virus was until recently considered a mild pathogenic mosquito-borne flavivirus with very few reported benign human infections. In 2007, an epidemic in Micronesia initiated the turnover in the epidemiological history of Zika virus and more recently, the potential association with congenital microcephaly cases in Brazil 2015, still under investigation, led the World Health Organization (WHO) to declare a Public Health Emergency of International Concern on February 1, 2016. Here, we present the clinical and laboratory aspects related to the first four imported human cases of Zika virus in Portugal from Brazil, and alert, regarding the high level of traveling between Portugal and Brazil, and the ongoing expansion of this virus in the Americas, for the threat for Zika virus introduction in Europe and the possible introduction to Madeira Island where Aedes aegypti is present.

  7. Everyday narratives on race and health in Brazil.

    Pagano, Anna

    2014-06-01

    In 2006, Brazil approved a groundbreaking policy aimed at reducing significant racial health inequalities among its citizens. Like health disparities programs in the United States, Brazil's policy is based on the assumptions that racial identity and racism are important health determinants and that citizens who identify as "black" suffer disproportionately from a number of health problems. How do these assumptions compare to Brazilian citizens' conceptions of racial identity and health inequalities? To address this question, I present ethnographic data from two years of fieldwork in Brazilian public clinics and low-income neighborhoods. I show that a majority of research participants made no connection between race and better or worse health. Of those who perceived health inequalities by race, most believed that white Brazilians had more health problems than black or brown Brazilians. Finally, I consider the implications of these ethnographic findings for Brazil's health disparities campaign. PMID:24719036

  8. Status [Brazil: A country profile on sustainable energy development

    International Nuclear Information System (INIS)

    The energy picture of Brazil today is that of a large, rapidly growing country in the midst of economic development with a reasonable supply of indigenous resources. Its current situation reflects its attempts to satisfy and accommodate competing needs and challenging sustainable development goals. This chapter reviews the current status of Brazil's energy system and how it developed. It is divided into four major sections: Section 2.1 presents the national energy balance; Section 2.2 assesses the country's energy status according to the economic, social and environmental dimensions of sustainable development; Section 2.3 highlights the institutional dimension of Brazil's energy system; and Section 2.4 summarizes the major issues facing that system

    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. PMID:27479998

    2014-12-01

    Full Text Available Hydroptila Dalman, 1819 is one of the most diverse genus of Hydroptilidae, comprising over 400 species distributed in all biogeographical regions. Only two species were previously recorded from Brazil. Here, three new species from Northeastern Brazil are described and illustrated. The new species can be distinguished based on the male genitalia: Hydroptila marighellai sp. nov. can be recognized by the pliers-shaped tergum X; H. florestani sp. nov. can be recognized by having inferior appendages curved upwards in lateral view; and H. zerbinae sp. nov. differs from the other species of the denza group in the apex of the tergum X, which is wide in lateral view, and the undivided apical portion of the phallus. These are the first records of species of Hydroptila from Northeastern Brazil.

  11. Plant poisonings in livestock in Brazil and South Africa

    2015-03-01

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

  12. Climatic factors influencing triatomine occurrence in Central-West Brazil

    Joyce Mendes Pereira

    2013-05-01

    Full Text Available We estimated the geographic distributions of triatomine species in Central-West Region of Brazil (CW and analysed the climatic factors influencing their occurrence. A total of 3,396 records of 27 triatomine species were analysed. Using the maximum entropy method, ecological niche models were produced for eight species occurring in at least 20 municipalities based on 13 climatic variables and elevation. Triatoma sordida and Rhodnius neglectus were the species with the broadest geographic distributions in CW Brazil. The Cerrado areas in the state of Goiás were found to be more suitable for the occurrence of synanthropic triatomines than the Amazon forest areas in the northern part of the state of Mato Grosso. The variable that best explains the evaluated models is temperature seasonality. The results indicate that almost the entire region presents climatic conditions that are appropriate for at least one triatomine species. Therefore, it is recommended that entomological surveillance be reinforced in CW Brazil.

  13. First isolation of enterovirus 71 (EV-71 from Northern Brazil

    2003-01-01

    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.

  15. Country nuclear fuel cycle profile: Brazil

    International Nuclear Information System (INIS)

    Brazil has two operating nuclear power plants: Angra 1, a 657 MW(e) Westinghouse PWR and Angra 2, a 1350 MW(e) Siemens KWU PWR. Both units are owned and operated by ELETRONUCLEAR. Angra 1 started operation in March 1982 (commercial operation since December 1984) and Angra 2 started commercial operation in February 2001. In 2002 the two plants produced about 4% of the country's electricity supply, of which more than 88% comes from hydroelectric plants. Brazil has not yet decided about its nuclear fuel cycle policy. The Pocos de Caldas CIPC mining and ore processing plant was closed in 1997. The Lagoa Real area Caetite unit started operation in 2000 with an initial capacity of 340 t U/a. As part of the Brazilian Navy's nuclear propulsion programme, a UF6 pilot plant with a nominal production capacity of 40 t U/a is under construction at the Navy Research Institute (CTMSP) at Ipero, 100 km from Sao Paulo. There are no plans to install a commercial plant in the near future. As part of its nuclear propulsion programme the Brazilian Navy has installed a demonstration enrichment centrifuge pilot plant at Ipero. Recently the Brazilian Government decided to start the industrial implementation of the ultracentrifuge process developed by the CTMSP in the Resende industrial plant in the State of Rio de Janeiro. The complete set of units is intended to be operating in 8 years to meet the needs of Angra 1 and partially those of Angra 2 and 3 (∼300 t SWU/a). A future increase in this capacity will depend on technical evaluation and resource availability. The two unit fuel fabrication plant of INB is located at Resende, Rio de Janeiro State, and has a production capacity of 280 t U/a. The fuel fabrication plant has been refurbished and produces the fuel rods and fuel elements for Brazilian nuclear reactors at its unit I. Unit II, which is responsible for pellet fabrication, has been operating since June 1999 with a capacity of 120 tonnes of UO2 pellets/a. The UO2 powder

  16. Making the case for grid-connected photovoltaics in Brazil

    International Nuclear Information System (INIS)

    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: → With the declining costs of PV and the rising prices of conventional electricity, Brazil will soon enjoy grid parity. → The availability of raw materials (Si and green electricity) make Brazil an ideal candidate to become an important player in the PV production scenario. → A feed-in tariff program in Brazil should be limited in time and size. → 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.

  17. The climate change/energy efficiencies market in Brazil

    International Nuclear Information System (INIS)

    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

Conclusion: The periodontal health of this population is covered with precariousness, mainly due to dental calculus and periodontal pocket.

  19. Educational applications on particle accelerators in Brazil

    International Nuclear Information System (INIS)

    The Brazilian production of radiopharmaceuticals and radioisotopes for medical usage dates back to the 70's, since the beginning up to 2006; it was a monopoly of the government-owned corporations. After the market was open for the private enterprise, the quantity of small particle accelerators is increasing. The difficulties are many, from industry installation to the hard time on finding qualified personnel. The lack of investment on this area brought few trained people and the trained ones keep working in the government laboratories. Facing this issue, a strong program was started on training and educating people on universities, businesses enterprises and at hospitals in order to increase the human resources capabilities in the country. Activities such as laboratory research and lectures are being made as well in order to adapt Brazil to the renascence of the nuclear technology and increase the knowledge in the field of particle accelerators. These investments on education are preparing professionals in several areas, such as: physics, engineering, pharmacy, medicine, administration, among others. It started on the universities not only with lectures and workshops, but also with research partnerships on the stand-by time of the particle accelerators. At clinics and hospitals the efforts are focused in the improvement and training of the particle accelerator product applications. One of the private enterprise corporations has trained more than 30 people from five different states and established partnership with five different universities, qualifying people on installation, operation, maintenance and administration of the whole process of implementation of a particle accelerator site. It's also collaborating with the universities and researchers in the development of new techniques: the irradiation of other material targets or the use of non-usual particle beams, allowing the study of the nuclear activation of the concrete walls of the particle accelerator

  20. URBAN WATERSHED STUDIES IN SOUTHERN BRAZIL

    Directory of Open Access Journals (Sweden)

    Cristiano Poleto

    2007-12-01

    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.

    In 1991, a survey conducted in northeastern Brazil by BEMFAM, the International Planned Parenthood Federation's affiliate, revealed that 15% of female adolescent respondents had children or were pregnant and that the fertility rate for adolescents aged 15-19 was 41 births/1000. In addition, the fact that 33% of all cases of HIV/AIDS reported between 1980 and 1996 involved 20-29 year olds means that a significant number were infected as adolescents. BEMFAM responded by launching (in 1993) a school-based adolescent HIV/STD prevention campaign in Alagoas state (where BEMFAM found the school in a deplorable state of filth, with every surface covered with graffiti) and in Paraiba state. Today the school buildings are clean, the graffiti is gone, and students are learning to talk openly about their bodies and sexuality. The most innovative aspect of the program is that sex education is incorporated in every part of the curriculum instead of being isolated in a separate course. History teachers incorporate gender issues in their discussions; math teachers use AIDS statistics in class; and other teachers discuss such issues as personal hygiene, sexuality, and unwanted pregnancy. The school staff received 40 hours of training in sexuality, reproduction, HIV, sexually transmitted diseases, communication and leadership skills, gender, and self-worth. A serious implementation impediment is the fact that Brazilian teachers are rotated annually from school to school, and new staff must be trained each year. The project has had beneficial results for all involved and has earned the support of the community at large. PMID:12293653

  2. Acute fasciolosis in cattle in southern Brazil

    Maria de Lourdes Adrien

    2013-06-01

    Full Text Available This study describes the epidemiological and pathological aspects of an outbreak of acute fasciolosis in cattle in southern Brazil. Fifteen out of 70 three-year-old pregnant cows lost weight in the 30-40 days prior to calving. Clinical signs included diarrhea, weakness, mild anemia and jaundice. Dark yellow fluid in the abdominal cavity was observed at necropsy. Fibrin and clotted blood were adhered to the pericardium and lung, primarily in the diaphragmatic lobes. The liver was enlarged, and the capsular surface was irregular with clear areas and petechiae. At the cut surface, the liver was irregular, firm and edematous, and several hemorrhagic channels could be observed. Areas of fibrosis through the parenchyma and whitish thrombi occluding the great vessels were also observed. The livers of 10 cows that not died were condemned at slaughter for lesions of fasciolosis similar to those observed at necropsy. Microscopically, the liver showed areas of coagulation necrosis, extensive hemorrhages in the streaks or foci and disruption of the parenchyma with neutrophil and eosinophil infiltration. Fibrosis and bile duct proliferation were also observed. Immature Fasciola hepatica flukes were observed in the parenchyma surrounded by degenerated hepatocytes, neutrophils, eosinophils, and hemorrhages. The outbreak occurred on a farm located in an area endemic for fasciolosis, although the acute form of the disease is not common in cattle in this region. It is likely that the cows were infected by F. hepatica metacercariae released in the late fall or early spring in the rice stubble where the herd was grazing prior to calving. Although mortality due to fasciolosis in cattle is infrequent, outbreaks can occur and treatments that are effective in both the immature and adult forms of the parasite should be administered to prevent economic losses.

  3. The Rio Doce Orogeny, Southeastern Brazil

    Neto, M. C. Campos; Figueiredo, M. C. H.

    1995-04-01

    The Neoproterozoic-Eopaleozoic superposed orogenic system of Southeastern Brazil, which was active during the Brasiliano-Pan-African Cycle during the assembly of this sector of the Gondwana Supercontinent, includes distinct terranes such as the Guanhães, Curitiba, Apiaí-Guaxupé and Serra do Mar microplates and the Juiz de Fora Thrust Belt. These orogenic systems also affected the reworked border of the São Francisco Craton. The collisional or ocean plate subduction-controlled "Brasiliano I" Orogeny was responsible for the generation of fold belts along the southeastern border of the São Francisco Craton, the accretion of different microplates and the formation of a magmatic arc associated with the roots of a northwestward trending thrust belt. The "Brasiliano I" evolution occurred during the Neoproterozoic and by 600 Ma was already in a post-orogenic stage in the Apiaí-Guaxupé Microplate, with the intrusion of rapakivi-like granitoids. The Rio Doce Orogeny is best characterized in the Serra do Mar Microplate by a magmatic arc, active between 590 and 570 Ma, with batholithic calc-alkaline plutonism exhibiting subduction zone components and a chemical zonation indicative of northwestward subduction. The collisional stage (560-530 Ma) accounted for the accretion of the Serra do Mar Microplate to the former orogenic domains. Anatexis of mostly metasediments producing peraluminous migmatites and granites, began at the calc-alkaline magmatic arc stage and culminated during crustal thickening associated with the northwesterly piling-up of large thrust slices. The post-collisional plutonism (520-480 Ma) is characterized by plutons and dikes of mainly alkali-calcic granitoids enriched in incompatible elements.

    The city of Curitiba, in southern Brazil, has been known for its environmental-friendly urban planning. Its quality of life has encouraged the natural growth of the city, which has doubled its population to over 1.3 million in the last 20 years while retaining 52 m of green area per inhabitant. In this article, the city's efforts to retain its success in the face of a growing population are documented. An integrated transport system has been created, a main commercial street was turned into a pedestrian street, the building of the Wire Opera and the Free Environment University was created, and the decentralization of the country's health system, and the launching of a program of waste sorting. All these accomplishments subsequently generated tourism, bringing in an income of about 4% of the city's net income. In addition, they have helped the 300,000 inhabitants of the city's slums with their rubbish by selling them carts on a low installment price. Migratory flow has been curbed since the creation of the Return House, wherein social workers offer free tickets to potential migrants; and the Vila Rural (Rural Town), consisting of small rural properties where peasant farmers will be able to farm in between industrial jobs. In conclusion, if Curitiba's Institute of Urban Research and Planning team is successful in transposing to the State its achievements in the municipal administration, by the year 2000 Curitiba will have proved to be the seed of a revolution that will improve the development of the whole region.

    Full Text Available Abstract Background Adverse events are considered a major international problem related to the performance of health systems. Evaluating the occurrence of adverse events involves, as any other outcome measure, determining the extent to which the observed differences can be attributed to the patient's risk factors or to variations in the treatment process, and this in turn highlights the importance of measuring differences in the severity of the cases. The current study aims to evaluate the association between deaths and adverse events, adjusted according to patient risk factors. Methods The study is based on a random sample of 1103 patient charts from hospitalizations in the year 2003 in 3 teaching hospitals in the state of Rio de Janeiro, Brazil. The methodology involved a retrospective review of patient charts in two stages - screening phase and evaluation phase. Logistic regression was used to evaluate the relationship between hospital deaths and adverse events. Results The overall mortality rate was 8.5%, while the rate related to the occurrence of an adverse event was 2.9% (32/1103 and that related to preventable adverse events was 2.3% (25/1103. Among the 94 deaths analyzed, 34% were related to cases involving adverse events, and 26.6% of deaths occurred in cases whose adverse events were considered preventable. The models tested showed good discriminatory capacity. The unadjusted odds ratio (OR 11.43 and the odds ratio adjusted for patient risk factors (OR 8.23 between death and preventable adverse event were high. Conclusions Despite discussions in the literature regarding the limitations of evaluating preventable adverse events based on peer review, the results presented here emphasize that adverse events are not only prevalent, but are associated with serious harm and even death. These results also highlight the importance of risk adjustment and multivariate models in the study of adverse events.

    Full Text Available The epidemiological data on snakebites in the state of Paraíba, Brazil, is scarce. This accounts for the difficulties in helping the victims. Hence, to obtain the clinical and epidemic profile of the snakebite accidents in Paraíba, we studied the number of cases recorded in this state between January 1995 and December 2000. The data was collected from these sources: Center for Toxicological Assistance (Centro de Assistência Toxicológica - CEATOX and State Secretariat of Health (Secretaria Estadual de Saude, João Pessoa; 3rd Regional Health Center (3º Núcleo Regional de Saúde - NRS and the Division of Epidemiological Vigilance of the Municipal Secretariat of Health (Divisão de Vigilância Epidemiológica da Secretaria Municipal de Saúde - DVE/SMS, Campina Grande. The annual distribution of the snakebite incidence showed an irregularity and an increase in March, May and August; followed by a large reduction in November and December. It was also observed that snakebites occurred more frequently in the rural area, mainly among the male laborers between 10-49 years. In most cases, the bite occurred on the leg or foot. The interval between the snakebite and the medical assistance was less than six hours. The most common symptoms were pain, edema, erythema, and bleeding. The low lethality index and the high frequency of healing, without sequels, suggest that the treatment with serum neutralized the poison, indicating the efficacy of this treatment against snakebites by the specific species found in this region.

    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

    This document is the Final Report for the project. Improvements in SISCOM II Technology. It consists of a brief description of the activities carried out during the project, and several Annexes that explain in a deeper way each result. SISCOM II is the main telemetry system currently in use in the Spanish underground coal mining, but it was developed ten years ago and needed a technological update, which was the objective of this project. The aims of the project were: - To develop Hardware and Software for the Outstations currently used (maintenance developments) - To design new hardware and software, easier to use in the current and new applications of SISCOM II Both objectives were met, although not in the way originally intended. The main results were: In the field of old Outstations update: - A new set of boards for the old Outstations was developed - Outstations`s firmware was updated for the new hardware In the field new hardware and software design: - SISCOM II Supervision software was completely rewritten, and now runs under Windows 3.11/Windows 95 (Originally it ran under DOS) - A new hardware configuration (the RELIA 2000), easier to assembly, install and re configure, together with its firmware, was developed Generally speaking the activities were carried out accordingly to the original schedule, with one exception, due to changes in the market of this type of Systems. Because of the changes, which happened by the end of the project`s time span, the structure of the new hardware was somehow different to the original design, although its functionality and performance is similar or even better than those of the original one.

    Full Text Available In this paper, some considerations, born directly from the field of the technologist community engaged in the research and development of largest machine built by mankind, the particle accelerator Large Hadron Collider (LHC at CERN, are presented. By this measuring machine, the technology played a crucial role for science, bringing it to new horizons. Conversely, at CERN, the key concepts of advanced physics have permeated the world of technology. For the technological research, a new cooperative model of public knowledge, free, meritocratic, and supranational, is born. For the technological researcher, a new awareness arises, based on the acceptance of his limits and those of the produced technology. But above all, based on the enthusiasm for a new role of the applied research, no longer dominated by profit, consumption or war, but for finally acting as free knowledge engine.

    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.
