    This study presents the characterization of the external geometry of deltaic oil reservoirs, including the description of their areal distribution using geo statistic tools, such as variography and kriging. A high-resolution stratigraphic study was developed over a 25 km{sup 2} area, by using data from 276 closely-spaced wells of an oil-producer field from the Reconcavo Basin, northeastern Brazil. The studied succession records the progressive lacustrine transgression of a deltaic environment. Core data and stratigraphic cross sections suggest that the oil reservoirs are mostly amalgamated, delta-front lobes, and subordinately, crevasse deposits. Some important geometrical elements were recognized by the detailed variographic analysis developed for each stratigraphic unit (zone). The average width for the groups of deltaic lobes of one zone was measured from the variographic feature informally named as hole effect. This procedure was not possible for the other zones due to the intense lateral amalgamation of sandstones, indicated by many variographic nested structures. Net sand krigged maps for the main zones suggest a NNW-SSE orientation for the deltaic lobes, as also their common amalgamation and compensation arrangements. High-resolution stratigraphic analyses should include a more regional characterization of the depositional system that comprises the studied succession. On the other hand, geostatistical studies should be developed only after the recognition of the depositional processes acting in the study area and the geological meaning of the variable to be treated, including its spatial variability scales as a function of sand body thickness, orientation and amalgamation.

    A higher application of bioenergy is one of the existing ways to adequate the necessity of an expansion in the energy supply with the mitigation of global warming. The consumption of biofuel in the transport sector is the most usual and important use of biomass, however, bioenergy may also have a relevant contribution to the world electrical matrix. A comparative analysis shows that Brazil has consolidate the usage of biofuel while Europe is having problems to accomplish the biofuels levels established in the European Union guidelines. However, some european countries are developing their bioelectrical generation potential in a much more efficient way than Brazil. Therefore , brazilian policies to support bioelectricity should observe the successful instruments applied in Europe. (author)

    Renewable energy have a prominent place among the solutions to combat global warming, but its potential is still untapped in Brazil. Without long-term policies with clear rules, you can not attract entrepreneurs and ensure stability of operation of this market. The main tools of government to promote renewable energy generation have not been efficient - the Incentive Program for Alternative Sources of Energy (Proinfa) was implemented in 2002 but put into operation just over two thirds of the energy proposal. The low success rate in repeated auctions focused on renewable energy. The objective of this paper is to discuss the prospects of the expansion of electricity generation by renewable energies in Brazil and some fundamental requirements for effective structuring of this market in the country. This argument is supported by the analysis of the proposed mechanisms used internationally and in the country, under a new law for renewable energies. As a practical demonstration of the analysis, we present a simulation of conditions of formation of the final price of renewable resources in different conditions as varied market rate of return, cost of transmission, and sale of carbon credits.

    The energetic analysis is the traditional method of quantification of the energy used in an operation involving physical and chemical processes and transference and/or conversion of energy. Generally used through energetic balance that is based on the first law of thermodynamics to evaluate the energetic efficiency. This balance is used to determine and reduce the loss of energy. Although an energy balance does not provide information about the energy degradation or resources during a process and do not quantify the potential or quality of the energy fluxes and material that flow in a system and come out as products and losses. The exergetic analysis goes beyond the limitations of the first law of thermodynamics. The concept of exergy is based in the second law of thermodynamics. The objective of this paper is to compare the more suitable analysis method aiming the identification of the energy economy potentials and consequently the reduction in the emissions of the greenhouse gases, through the balance of mass, energy and exergy of the blast furnace 1 of V and M do Brazil.

    In recent years, the exploratory interest on Cumuruxatiba Basin has been inconstant, with modest discoveries of oil. Aiming to deepen the geological knowledge of the basin and in order to attract the interest of oil companies, the ANP (National Agency of Petroleum, Natural Gas and Biofuels) signed contract with COPPE/UFRJ for carrying out an analysis basin project. The project was developed by the Basin Analysis Multidisciplinary Modeling Laboratory (Lab2M/UFRJ) in the period 2006/2007, and was with the main objective outline the main structural and seismo-stratigraphic features of the basin, and in an integrated and multidisciplinary way, build a model of its sedimentation and tectono-stratigraphic evolution. This paper presents the results of the regional seismic mapping, aided by well and potential methods data. The stratigraphic succession the basin has been divided into genetic units (UN-B, UN-C e UN-D) corresponding to second order depositional sequences, they are: UN-B, corresponding by a rift and sag-rift siliciclastic deposits, plus the Aptian evaporitic deposits; UN-C, characterized by carbonatic deposits, and shelf related sediments; and UN-D, corresponding by a final transgressive (siliciclastic) - regressive (mix) cycle, between Cenomanian and actual days.

    The Agencia Nacional de Petroleo - ANP - created in 1997 by the petroleum law has the role of regulating oil and natural gas industry activities in Brazil inciting the power self-sufficiency. The petroleum law states the end of petroleum exploration monopoly in Brazil performed by PETROBRAS. Between 1998 and 2004 ANP carried out six bid rounds in brazilian sedimentary basins offered to national and foreign companies. The exploratory activities in Bahia are resulting in commercial discoveries and positive impact to local economy. The petrochemical industry expects the startup of Manati field operation to supply repressed demand of natural gas as fuel and raw material. This article analyzes the legal and institutional processes and economics performances of these activities in Bahia's state. (author)

    Nowadays, the intense investment in renewable energy reflects the search for alternative solutions to politician-economic and socio-environment originated by energy' source predominance of fossil origin in the global energy matrix. In this case, the ethanol from Brazil's sugar cane is more and more writing your history on the International bio fuels market. That's mainly due to Brazil's commercial maturity, agricultural, technological achieved in last decades. However, some negatives socio environments, such as deforestation, fires and precarious job conditions, among others are a discredit for a probable future hegemony of Brazilian ethanol. In this way, it is important to set guide-line discussions about this topic, analyzing and overcoming problems that avoid a better sustainable posture. (author)

    Introduced at the end of the 1970s to study the impacts of structural changes on electricity consumption by industry, index decomposition analysis techniques have been extended to various other areas to help in the formulation of energy policies, notably in developed countries. However, few authors have applied these techniques to study the evolution of energy consumption in developing countries. In Brazil, the few available studies have focused only on the industrial sector. In this thesis, we apply the decomposition technique called the logarithmic mean Divisia index (LMDI) to electricity consumption of the Brazilian residential sector, to explain its evolution in terms of the activity, structure and intensity affects, over the period from 1980 to 2007. The results obtained in a preliminary analysis point out, in a general way, that the observed variables in electricity consumption in the Brazilian residential sector are, mainly, the product of the increase in the number of consumers and the changes in the specific consumption of electricity in households. In a further analysis, carried out when the structure is given through consumers participation in consumption categories (Low Income and Conventional) taken from an overall point of view, although the intensity and activity effects may be considered the main explaining factors in consumption variation, the structure effect stands out in the period immediately after the 2001 rationing, as a reflect of the changes in the inclusion criteria in the Low Income category, specifically in the Northeast.

    This paper documents the analysis of seismic data of the Espirito Santo basin obtained during the project realized through partnership between COPPE/UFRJ/Lab2M with the Agencia Nacional do Petroleo, Gas Natural e Biocombustiveis (ANP) during 2006 and 2007. The major objective of the seismic data interpretation in the project was to define the main structural and stratigraphic features in order to build a sedimentation model and a tectonic-stratigraphic evolution model of the Espirito Santo basin. Thus, the sedimentary package has been divided into eight genetic units (UN), grouped into five third order stratigraphic sequences, namely: UN-B, represented by siliciclastics rocks of the rift stage and evaporitic sag-rift stage, deposited during the Aptian; UN-C, which represents the carbonatic rocks deposited in a marine environment, and siliciclastics rocks located in the proximal portions during the Albian; and UN-D, represented by sediments, composed mainly by pelites, deposited in between the Cenomanian and Recent, and includes the Eocene volcanic event, which one changed the sedimentation pattern of the basin.

    The main fuels for vehicles in Brazil are the gasoline type C - which is a mixture of gasoline, resulting from the fractional distillation of oil and anhydrous ethanol - and hydrated ethanol. For this importance, has been created an institutional framework to guide and regulate the activities of the fuel sector, initially for gasoline, hydrated ethanol was contemplated by such device in 2011. Since 2003, there has been manufactured in Brazil the flex-fuel vehicles. With this, the possibility of activation of an additional factor for the regulation of vehicle fuel prices, increasing consumer power to define which of the fuels could be used as the disposition of their prices. One of the effects of growth flex-fuel sales has been increased production and investment in ethanol (especially sugar cane) as a suitable alternative to the. The hope was that the formation of fuel prices was less dependent on their cost of production and distribution and more influenced by a pressure of consumer demand. However, the increase in the sales of the flex-fuel vehicle in Brazil in the last years was not the determining factor in the price of fuels, as it was expected. The explanation of this is on external factors to the automotive industry, linked to the structures of the production chain of oil and ethanol, especially the question of the great increase in international prices of oil and hydrated ethanol in the international market in recent years.

    The Brazilian electric energy matrix is mostly renewable. According to the Generation Information Base (BIG) of the Brazilian Electricity Regulatory Agency (ANEEL), hydroelectricity is responsible for 67.31% of the country's energy. The additional generation comes mostly from fossil fuels, whose use is questioned when it comes to environmental quality and climate change. Despite its abundance, hydroelectric power generation has physical, socioeconomic and environmental limitations. Thus, it is essential to develop alternative technologies, providing security in the supply of electric energy and the maintenance of a clean matrix. Among the alternative technologies available, wind power is the one that has been gaining prominence, domestically and internationally speaking. In the last auction of renewable sources held in August 2010 in Brazil, the energy produced by the plants of sugarcane bagasse (biomass) was traded at an average of R$ 144.20 MWh; wind energy, which was the cheapest, was traded at R$ 130.86, and the energy from small hydropower plants (PCH), at R$ 141.93 MWh. The wind power plants accounted for 70% of the auction, which resulted in a plan for increasing its installed capacity by fivefold, by the year 2013. Brazil has great potential to be explored (estimated 143,000 MW), yet despite being appealing, wind energy still face some challenges. One of them is due to the fact that most potential areas for such energy are found in permanently preservation areas and areas considered national assets, subject to special protection measures. This study aims to investigate whether the regulatory, legal and environmental issues are considered an obstacle to an effective inclusion of wind power generation in Brazil. The study examines the process of environmental licensing of wind power plants, especially those established in permanently preservation areas (APPs) and Coastal Areas. The research methodology consisted of normative framework, judicial decisions

    This thesis focuses on the technologies related to CO{sub 2} capture and geological storage. The main objective of this study is to perform an analysis of the technical potential of geological sequestration of CO{sub 2} in the oil and gas sector in Brazil. Climate changes are directly related to emissions of greenhouse gases. Mainly, are related to increased carbon dioxide emissions due to the use of fossil fuels. To mitigate climate changes there are technologies that have the purpose of promoting the reduction of emissions of greenhouse gases such as the Geological Sequestration of CO{sub 2}. Thus, the study presents a description of the stages of the geological sequestration of CO{sub 2} and the state of the art of the technology in Brazil and worldwide. In addition, is presented the capacity for storage of the Brazilian sedimentary basins. Finally, this thesis analyzes the application of the described technologies in two stationary sources of great importance: refineries and oil and gas production fields. (author)

    The recent moves towards the insertion of biofuels in the energy matrix of a number of countries are opening new prospects for agricultural production and for agroindustrial chains. This study aims at understanding the mechanisms taking place within a production system geared towards biodiesel production. The emergence of this new productive base raises new research issues: in what circumstances are the structuring, organization and implementation of these biodiesel productive chains taking place in Brazil? What are the effects of biodiesel production on local economies? Hence, the central objective of this study is the development and validation of an analytical structure capable of characterizing the biodiesel productive arrangements and identifying their economic and social impacts at the regions where they are installed. A preliminary analysis identified that a biodiesel productive arrangement is emerging in the State of Piaui, Northeastern Brazil, Our theoretical basis comprises elements from the regional economy, biorefineries, local production arrangements and innovation. For the analyses, we employed the methods of input-output, local quotient and shift-share. It can be said that a new social-economic dynamics is taking place in Piaui; however, the company needs to assess its interaction with local institutions as well as its castor bean production strategies.

    The present article intends to estimate the direct and indirect emissions of carbon dioxide through of the Brazilian economy official data (IBGE) and data from the National Energy Balance (BEN), trying to correlate the results. For this, the decomposition methodology was used by indexes (IDA). In that sense, evaluations were made in the temporary variations of indicators as: pollution coefficient, energy intensity, effect structures and economical activity. Besides the evaluation of the results consolidated for the period 1970 - 2004, it was compared such results with the one of other countries, whose savings have relative similarity with the Brazilian economy. The results demonstrated that in Brazil and in the countries where the methodology was applied was obtained, as main indicator in the alterations of the emissions of CO{sub 2}, the level of economical growth, which is also reality to Brazil. However, it should be emphasized that each case is considered by other factors. Another contribution of the present study refers the comparison of the intensity of present carbon in the two analysed savings. It identified, still, that the Brazilian energy outlook, for being 'cleaner', propitiates positive impact on carbon emissions results. It was also demonstrated that the increase of the participation of the natural gas in the energy matrix could minimize the carbon intensity effect, mainly as alternative for the power generation and transportation.

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

    Radiation therapy services provide essential therapeutic procedures for cancer, one of the main causes of population morbidity and mortality. Despite their importance in the health system and their potential risks due to the use of ionizing radiation, there are few studies on such services. We evaluated compliance with technical standards for radiological protection in radiation therapy services in Sao Paulo State, Brazil. Forty-nine services were studied in 2000 through interviews with technical staff. Typologies of performance profiles focusing on structure and process variables were constructed and services compared. Important differences were observed in the services' positions in the health care system, level of complexity, and geographic distribution, with better average performance in structural conditions but very inadequate performance in patient protection, indicating the need for more effective health surveillance.

    The internal lining in gas pipelines aims the reduction of roughness and, consequently, the friction factor, therefore resulting in a reduction of pressure drop in natural gas flowing. During Bolivia-Brazil gas pipeline basic design, the cost benefit of internal coating was analyzed, in terms of friction factor reduction and distances between Compressor Stations. It was observed an increase of transport capacity and reduction of compressors' power, thus leading to its utilization. Since the pipeline is already in operation, using a SCADA system with Advanced Functions, a comparison between the current real friction factor in the pipeline with that theoretical values used during the design phase becomes possible. Through this comparison, it is possible to evaluate internal coating's efficiency, quantifying its real benefit for gas pipelines. (author)

    Although the Brazilian gas market has been showing steady growth and positive news regarding new discoveries, it is not immune to be questioned about its capacity of value generation, and, in particular, if the new companies, operating in distribution have generated it. Value creation, and its management, has become one of the main activities of the modern corporation in order to align the management and shareholders interests. Despite its advancements, the Brazilian NG industry can be considered at its early stages when compared to those of other countries whose industry is more traditional and mature. The process of unbundling of the gas industry, as well as of the public utilities, has become one of the icons of the Brazilian government policies since the mid 90's. Taking into account regulatory change which had only allowed in the last couple of decades the participation of private ownership into the domestic gas market, a follow up of these companies' performances is of interest. Following the concept of value generation, the present study examines the Brazilian gas distribution sector. Based on a detailed analysis of the financial statements of some of the main companies in the sector, that together represent around 68% of the total Brazilian market, this paper verifies whether the gas distribution sector have presented a positive or negative EVA{sup R}, in other words, if, during the period from 2002 to 2007, these newly companies in the gas industry have created or destroyed value in Brazil.

    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

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

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

    The South American Platform in southeastern Brazil records a long history of tectonic magmatic and uplift events, which resulted from the opening of the South Atlantic Ocean, Cretaceous reactivation and epirogeneic processes. Specific manifestations include the basic magmatism of the Serra Geral Formation of the Parana Basin and alkaline magmatism of Pocos de Caldas - Cabo Frio Lineament, as well as the uplift of the Serra da Mantiqueira and Serra do Mar mountain ranges. Thermo tectonic and geochronological studies using the K-Ar method and apatite fission track analysis in samples of the Pocos de Caldas alkaline massif show an initial evolution beginning 89 Ma related to a tectonic uplift, interpreted as related to the intrusion's doming. This was followed by an important episode of rapid cooling related to the formation of the massif. At the same time, the mountains that surround the massif record heating events in response to the alkaline intrusion, between 70 and 50 Ma. Periods of slow uplift, probably related to the South American Erosion Cycle (between 50 and 30 Ma) and Velhas Erosion Cycle (from 25 Ma), indicate a strong manifestation of denudation in this area.

    The region of Alfenas, in the state of Minas Gerais, Brazil, is predominantly constituted of Pre-Cambrian rocks with well developed alteration profiles in association with colluvial and alluvial sediments. No study to date has examined in detail its potential use in the ceramic industry. The scarce knowledge of its mineralogical and technological properties limits its value and consequently its industrial use. Until now, these clay materials have been used in a rudimental manner, in small scale in the fabrication of red tiles. The present study aimed at analyzing these clays mineralogically (X-ray diffraction), chemically (major and minor elements by X-ray fluorescence and organic carbon analysis) and technologically (pressing granulometric distribution; mechanical resistance; water absorption, apparent porosity; linear firing shrinkage; color of firing and others) in order to better understand the raw material and develop adequate technological applications. The best results of ceramic properties were the samples with higher organic content (more plastic clays) and higher values of Al{sub 2}O{sub 3} (kaolinite and gibbsite) and Fe{sub 2}O{sub 3} as well lower SiO{sub 2} content and finer grain size which contribute to a better sintering.

    Sorption of the metallic elements in aqueous solutions in surface of the hydroxides affects the transport of heavy elements in the freshwaters. Sorption and the chemistry of the hydroxides are important studies for knowledge in geology, waters and waste treatment, and environment studies. In the industrial mining region areas, the river surface waters are subject to modifications in its physical and chemistries properties: pH, DBO, conductivity and alkalinity. Instrumental neutron activation analysis and inductively coupled plasma-mass spectrometry (ICP-MS), have ben used for the determination of toxic heavy metals and others pollutants in the Das Velhas river in State of Minas Gerais, in south-east Brazil. Water samples were collected with acidification on site, which provoked a change of its natural pH. Consequently, metallic elements associated to hydroxides and to particles in suspension were liberated. The objective of this paper is to show the different behavior of any elements, in water of Das Velhas river, with relation of its chemical forms (cations or anions), the solubility degree, the pH and the presence of rare earth elements.

    The natural gas pipeline transport is carried out by one or more compression stations. Each station possesses one or more compressors. The compressor's fuel is usually natural gas itself. The amount of natural gas consumed by the compressors fluctuates daily according to the demand at the city-gates. The daily operational result of a pipeline is known as imbalance. The imbalance is the difference between the natural gas entering into a in a pipeline and the volume delivered in the city-gates added to system use gas. The imbalance analyses in a pipeline that uses natural gas powered compressors requires the analyses of the system use gas. The aim of this work is to study the system use gas in the Bolivia-Brazil pipeline using the available data from the Superintendencia de Comercializacao e Movimentacao de Petroleo, seus Derivados e Gas Natural - ANP and compare the change of the volume consumed before and after the entry into operation of the Campinas-Rio gas pipeline.

    The current actions of economic and industrial activities have resulted in increase of the concentration of greenhouse gases in the atmosphere since 1750. According to IPCC (2007) this alteration can increase the average temperature in the planet between 1,8 and 4,0 deg C up to 2100. The climate changes and the global warming are the most complicated environmental questions of our time and the actions took now will have effect on the future generations. In this context, a series of world-wide conferences and diverse scientific quarrels had occurred throughout the last decade, which culminated in the most important multilateral agreement firmed on climate changes, the Kyoto Protocol, signed in 1997. The Protocol is a landmark in the attempts of mitigation of the climate changes, since it established the commitment of the industrialized countries with emissions reduction targets of 5,2% to the level of 1990 emissions. To achieve such targets these countries count on three flexibilization mechanisms provided by the Kyoto Protocol: Joint implementation, Emission Trading and the Clean Development Mechanism (CDM) that it will be object of this study. The objective of this thesis is to carry through an evaluation of the CDM since its conception until the current days, searching to identify its dynamics and the main inherent gaps of this instrument and finally present two case studies of the bio diesel and wind energy uses in Brazil.

    The objective of this work is the study of the natural gamma radiation at the Areia Preta Beach (APB) in Guarapari, state of Espirito Santo, Brazil. The level of this radiation is dependent on the concentration of the radioactive mineral monazite in the sand. Probable risks of the exposure to gamma radiation at the APB were evaluated by the preliminary environmental risk analysis technique. For this purpose were conducted two annual sets monitoring gamma radiation in the APB every two months and so, acquired the seasonal variation of the radioactive levels. Additional/y was investigated the granulometry of the heavy mineral fraction and also carried out electronic microscopic scanning and radiometric age dating of the monazites of the APB, the mineral separation by magnetic susceptibility, and the mineralogic determination of the sediment. In order to gain a more complete picture of the seasonal variation, and, consequently, of the risk of exposure to ionizing radiation at the APB, the radiometric variation was also studied at some other beaches in the same region. The results indicate that the highest radiometric values are measured in summer and the lowest in winter. The radiometric dating of the monazites from the APB revealed the ages of 475 and 530 Ma. The Preliminary Hazard Analysis indicates a minimum risk of excessive radioactive exposition. It would take a period of approximately 870 years of a beach fully crowded to result in one case of bad consequences due to exposure to gamma radiation. (author)

    The Araripe Basin, located in the Borborema Province, northeastern Brazil, developed through a sequence of distinct events related to the opening of the South Atlantic. Its geological history is recorded in the preserved stratigraphy, which ranges in age from Paleozoic to Middle Cretaceous. The most conspicuous feature associated with the Araripe Basin is the Araripe Plateau, a large mesa capped by Cenomanian- Albian non-marine sandstones (Exu Formation). At the plateau base, gray to black shales ('Batateiras layers') represent deposition in a large lake system covering part of northeastern Brazil during Early Aptian. Previous researchers have used the preserved geological section in the basin to infer the landscape evolution of the Araripe Plateau, and they have suggested that its uplift and exhumation were caused by widespread epeirogenic movements associated with post-break-up events in the Borborema Province. Independent constraints on the timing and magnitude of uplift in the Araripe Plateau area can now be introduced by this preliminary study using apatite fission track analysis. A series of samples along a N-S transect of the Araripe Basin and its neighboring basement provide clear evidence of heating in the past. Results from all samples also show evidence of Late Cenozoic cooling commencing sometime in the last 40 Ma. Maximum paleotemperature associated with this event are very similar (70 deg - 90 deg C) between samples, consistent with little differential movement across the sampled region. Fission track results from the Aptian sandstone sample (Rio da Batateira Formation) indicate an earlier event (pre-40 Ma). However, interpretation of data suggests that any paleo-heating between sediment deposition (112 Ma) and 40 Ma must be associated with paleotemperature less than {approx}100 deg C, pointing to minor paleo burial during the Late Cretaceous in this area. The timing of these various events are broadly consistent with the timing of events

    Results of apatite and zircon fission track analysis of samples from the Serra de Santana mesa provide quantitative constraints on the depositional age of the nonfossiliferous Serra do Martins Formation. This unit consists of sedimentary remnants preserved at high elevations on the Borborema Plateau and its distributions and age are considered important in understanding the geomorphological evolution and denudation history of northeastern Brazil following the early Cretaceous breakup. We also report apatite fission track results from post-rift units of the Potiguar Basin (Acu and Tibau formations). Apatite fission track analysis (AFTA) of samples from the Serra do Martins Formation suggests that they reached maximum paleotemperatures around 60 deg C, from which they began to cool some time between 30 and 0 Ma. Due to the high thermal gradients related to the prolonged Cenozoic volcanism in the study area, we hypothesize that the paleotemperatures modeled for those samples may be related dominantly to an anomalous heat flow, rather than to significant burial. Zircon fission track analysis (ZFTA) in two samples of the Serra do Martins Formation yields ages of 135 {+-}18 Ma and 165{+-}40 Ma, but both samples show a significant spread in the data, and the youngest population of grains in these samples are characterized by ages of 83{+-} Ma and 65{+-} Ma, respectively. As the AFTA data show that these ages have not been reset after deposition, the zircon fission track ages must represent inherited provenance ages, demonstrating that those sediments can be no older than Paleocene. Independent lithological observations provide additional support to reject a stratigraphic correlation between the Serra do Martins and Acu formations. Combining the AFTA and ZFTA results, and integrating available geological evidence, we suggest that the Serra do Martins Formation was deposited some time between 64 and 25 Ma (Paleocene-Oligocene). Modeled thermal history solutions from AFTA in

Among these pathogens, Pseudomonas aeruginosa, one of the leading causes of nosocomial infections, is frequently found in water lines supplying dental units. In the present work, 160 samples of water, and 200 fomite samples from forty dental units were collected in the city of Barretos, State of São Paulo, Brazil and evaluated between January and July, 2005. Seventy-six P. aeruginosa strains, isolated from the dental environment (5 strains and water system (71 strains, were tested for susceptibility to six antimicrobial drugs most frequently used against P. aeruginosa infections. Susceptibility to ciprofloxacin, followed by meropenem was the predominant profile. The need for effective means of reducing the microbial burden within dental unit water lines is emphasized, and the risk of exposure and cross-infection in dental practice, in special when caused by opportunistic pathogens like P. aeruginosa, are highlighted.Uma ampla variedade de patógenos oportunistas tem sido detectadas nos tubos de alimentação de água dos equipos odontológicos, particularmente no biofilme formado na superfície do tubo.

    This Selected Issues paper examines infrastructure investment in Brazil. Brazil has inferior overall infrastructure quality relative to almost all its export competitors. Brazil’s infrastructure endowment ranks low by international standards, and its low quality affects productivity, market efficiency, and competitiveness. Areas in which Brazil’s competitiveness has lagged include, but are not limited to, education, innovation, governance, and justice. Brazil’s infrastructure gap has be...

  5. 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)

    Remotely-operated SHRIMP dating of zircon is an interesting alternative for dating of zircon crystals. Although it does not represent any technical progress of the geochronological method using the U-Pb system in zircon it is a very useful and cheap facility. The procedure was first used for mass spectrometric analyses involving two international laboratories in Sao Paulo, Brazil and Beijing, China. It was applied to samples of three gneiss-migmatitic rocks from the Ita quarry in the Atuba Complex (located between the Luis Alves and the Apiai Domain) to test previous controversial hypotheses about its evolution. The presence of important archaean and paleo proterozoic components in the complex is confirmed by analyses of zircon found in probably neo proterozoic leucosomes. Diorite intrusion also occurred during the neo proterozoic, associated with the 0.6Ga continental collisions involved in the assembly of Gondwana. The determination of Hf isotope ratios by LA-ICP/MS represents a new option for checking the relative importance of mantle ({epsilon}{sub Hf} > 0) and crustal contributions (({epsilon}{sub Hf} < 0) during the growth of the zircon crystals. While the archaean component in the complex was derived from the mantle ({epsilon}{sub Hf} + 1.5 to + 8.7) the paleo proterozoic component had a crustal contribution ({epsilon}{sub Hf} - 9.1 to -10.1).

    The dissertation presents the aspects related to the restructuring of power systems in terms of international experiences, and the possible implications for the definition of the new power system in Brazil. The experience shows that the reform in various countries has started from the sector deverticalization, together with the transmissions open access scheme. The retrospect of researched countries indicates that the transmissions remuneration is based on a methodology that recovers the operative cost of transmission transactions, along with an additional amount that take into account the cost of the existing transmission system. The following countries have been analyzed: Chile, Norway, England and Argentina. This work also shows the current situation in Brazil, as in terms of tariffs, as regarding the power system organizational structure, as well as a preliminary proposal conceived by SINTREL (National System of Electrical Energy Transmission) to evaluate the transmission transaction cost. This dissertation ended with comments and conclusions, depicting a future program which might be followed, considering the aspects quoted above and the peculiarities of brazilian power system.

    The Fricke dosemeter has been used for absolute determination of the radiation dose between 40 and 350 Gy for X-rays, Gamma rays and fast electrons energies. The great inconvenient of that dosimetric system is the impossibility of using for measurements of exposure or low dose rates. A Fricke dosimetry system was implanted at the Nuclear Sciences Regional Center (CRCN), in Recife, Pernambuco state, Brazil, for the determination of radiation doses for spectrometry and mass dosimetry with plasma source. The statistical analysis of the obtained results have shown that using the spectrometric method that system cna be used for maintenance of factors of CRCN standard calibrations and the dose assessment thru mail system of radiotherapy centers of the country.

    Passarelli, Claudia Regina

    1996-12-31

    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 activity of poultry raising is today an alternative for income generation in the backlands of Pajeu, State of Pernambuco. In the City of Sao Jose do Egito, distant 402 km from the State Capital Recife, there is a large poultry plant with 284 integrated poultry farms owned by small rural producers. Those poultry farms are built in masonry and lateral woven wire fencing within the standard size of 9 m X 125 m. Their capacity is 10,000 birds and they are equipped with drinking and feed boxes, silos, fans, nebuliser, motor-pumps, lights and heaters. In their first 18 days of the bird's life, called 'baby chick phase', it needs a warm environment temperature of about 34 deg C, which is fundamental for its survival. In that phase the energy consumption is mainly related to water pumping and lighting. From the 19th day up to the 45th day - the period called 'poultry phase' - the birds need lower temperatures. The feeders are automatic, fans and nebulizers are used to ease the air circulation and to improve the poultry comfort. This phase is the one, which requires more electric energy consumption. After 45 days the poultry is slaughtered with about 2.8 kg and the poultry farm comes into a time period of cleaning and resting called 'cleaning and resting phase', which takes from 15 to 28 days. This is the phase with the lowest energy consumption. Then the poultry farm cycle is completed, which takes about 70 days, that is, the time span of one year accounts for 5.5 cycles. In this work an energy consumption analysis for all phases of poultry raising is performed and alternative proposals for the energy conservation and energy consumption reduction is presented.

    Food borne diseases, in particular gastro-intestinal infections, represent a very large group of pathologies with a strong negative impact on the health of the population because of their widespread nature. Little consideration is given to such conditions due to the fact that their symptoms are often moderate and self-limiting. This has led to a general underestimation of their importance, and consequently to incorrect practices during the preparation and preservation of food, resulting in the frequent occurrence of outbreaks involving groups of varying numbers of consumers. Despite substantial efforts in the avoidance of contamination, an upward trend in the number of outbreaks of food borne illnesses caused by non-spore forming pathogenic bacteria are reported in many countries. Good hygienic practices can reduce the level of contamination but the most important pathogens cannot presently be eliminated from most farms, nor is it possible to eliminate them by primary processing, particularly from those foods which are sold raw. Several decontamination methods exist but the most versatile treatment among them is the ionizing radiation procedure. HACCP (Hazard Analysis and Critical Control Point) is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. For successful implementation of a HACCP plan, management must be strongly committed to the HACCP concept. A firm commitment to HACCP by top management provides company employees with a sense of the importance of producing safe food. At the same time, it has to be always emphasized that, like other intervention strategies, irradiation must be applied as part of a total sanitation program. The benefits of irradiation should never be considered as an excuse for poor quality or for poor handling and storage conditions, i.e.. as a substitute for good manufacturing practices. By adopting an HACCP based approach to food safety management, it can be clearly demonstrated that the application of a technology like food irradiation is essential for ensuring the safety of raw food stuffs. Such an intervention should be considered as a CCP (Critical Control Point) in the food chain. Therefore, the potential benefit of irradiation, which is endorsed by national and international bodies surely merits serious consideration by public health authorities, industry and consumer groups worldwide. For such, a system of HACCP and the irradiation is primordial so that the alimentary .safety is maintained processes if they are applied correctly. (author)

  17. The use of chemical and isotopic data as indicators of the origin of waters and dissolved salts in the Bambui calcareous aquifer (Bahia-Brazil)

    International Nuclear Information System (INIS)

    Samples of 25 wells located in the Bambui limestone aquifer in the region of Irece - Bahia, have been analised for the isotopic ratio 18O/16O and the major chemical species Ca, Mg, Na, K, Cl, SO4 and bicarbonate. The oxygen-18 data have been found to range between -2,62/00(in a thousand) to -6,66/00(in a thousand) relative to the universal Standard Mean Ocean Water (SMOW) and are compared with the values of the precipitation in the localities of Jacobina and Lencois (meteorological stations nearby) and with the values of the groundwater in sedimentary basins in northeastern Brazil. The comparison suggests that aquifer system is recharged by precipitation originated in northeastern Brazil, instead of originating on coast of Bahia, east of the area. Furthermore, the waters in aquifer are not found homogenized, having widely varying 18O and chemical composition and being of different ages. The strong correlation between the observations Ca, Mg, Na, Cl and TDS (total dissolved solids) suggests an aerosol origin of salts, not excluding the hypothesis of dissolution of rock, which concentrations. The comparison of characteristic ratios Mg/Ca, SO4/Cl and (Cl-Na)/Cl, a Piper diagrama and a dendrogram established by cluster analysis, indicates that the wells may be separated in to two groups according to the isotopic or geochemical environment to which they belong. These groups may represent the differents sources of salt proposed, one being from the limestone, the other having come from aerosols. (Author)

These factors, in combination with the slower than anticipated growth in electricity demand, have been instrumental in curtailing nuclear power development in the country. Following recommendations advanced in a commissioned study for improving Brazil`s nuclear program, Brazilian President Jose Sarney announced on August 31st the restructuring of the country`s nuclear industry.

    International Nuclear Information System (INIS)

    Brazil is a country of vast natural resources, including numerous uranium deposits. 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

    Full Text Available Dorsal spines (n=649 of the queen triggerfish Balistes vetula were collected between 1997 to 1999 at the central coast of Brazil and used to evaluate fish growth. The marginal increment analysis validated that 1 increment was formed annually (n=476, with minimum values observed at the summer, and coinciding with the maximum proportion of translucent growth bands. Fish's maximum fork length and age were 460 mm and 14 years respectively. The parameters of the von Bertalanffy function were: Fl∞ = 441.3 mm, K = 0.14 and T0= -1.8. Weight gain by year ranged from about 110 g yr-1 for age 5 to about 30 g yr-1 for age 14. Compared to other studies, B. vetula growth in the Central coast of Brazil was slow, which could be related to the influence of the oligotrophic water from Brazil current. Our results indicate that B. vetula's fisheries in the Central coast of Brazil until 1999 have caught mostly adult individuals over the sexual maturation lenght, 60% of them with ages from 6 to 8 yr.Entre 1997 e 1999 foram amostrados 649 espinhos de Balistes vetula na costa central do Brazil e foram utilizados para a avaliação de crescimento. A validação de anéis anuais de crescimento foi realizada através da analise de incrementos marginais, cujos valores mínimos foram observados durante o verão, coincidindo com a maior proporção de anéis translúcidos na borda do espinho. Portanto, forma-se um anel de crescimento a cada ano. A idade e o comprimento padrão máximos observados foram respectivamente 14 anos e 460 mm. Os parâmetros da equação de von-Bertalanffy foram: Fl∞ = 441,3 mm, K = 0,14 e T0= -1,8. O incremento anual em peso variou de 110 g yr-1 para a idade 5 a 30 g yr-1 para a idade 14.

    This paper analyses the institutional model adopted for the reform of the oil industry in Brazil, beginning with the approval of Law n. 9.478 by the Brazilian Parliament in 1997. The reform of the Brazilian oil industry took place in the context of the reforms of the world's national economies throughout the 1980's and 1990's. From this worldwide process of reform stemmed a huge increase in the international capital flow directed to long-run investment opportunities in the economic infrastructure sectors. The aim of this paper is to analyse both the regulatory model for the oil and gas upstream activities in Brazil and the bidding model adopted at Brazil's National Petroleum Agency's auctions for the acquisition of exploration areas. This paper is dedicated, in its entirety, to Prof. Carmen Alveal (in memoriam), whose knowledge, support, encouragement and friendship were, for me, the most important of all, professionally and morally.

    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.

Paulo, function as points of attraction for these Gravimetric Centers (GCs towards the south as compared with the GCs of the general population calculated ia accordance with data from the 1980 and 1991 censuses. It is possible to observe a displacement of the GCs toward the northwest over this period in accordance with the migration patterns of the Brazilian population in general, though with a dynamic of its own. These changes in the geographical, socio-demographic and transmission group patterns show the complex nature of the epidemic in Brazil and pose additional difficulties for the development of prevention strategies.

  14. Eand P opportunities in Brazil

    Energy Technology Data Exchange (ETDEWEB)

    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.

  15. 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

    2015-01-01

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

    For Brazil it is important to realize a high local production share because of high import tax rates. The rim drive concept offers an alternative for expensive heliostat drive solutions with slew and linear drives from abroad. By (locally produced) rims the demands on the drives regarding strength and precision are reduced to a very low value and low cost drives can be used. Sandwich facets (which are usually foreseen for rim drive heliostats) are not available from Brazilian manufacturers an...

    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.

    Repairing and maintenance activities on Bolivia-Brazil gas pipeline often need blow down lines. During the blow down process, the high speed of discharging gases imposes great efforts to the structures. A detailed analysis of this situation is essential for a safe operation. This paper describes two phases of a project, developed under TBG coordination. It consists in analyzing the stress and forces involved in this operation, in order to design facilities to blow down pipes and develop a safe blow down procedure for the gas pipeline. The first phase consists of a supersonic flowing simulation in the blow down gas pipeline device. The pressure behavior, mass flow and the speed at the device's ending point are calculated for different operational conditions. In the second phase, the equivalent loading caused by blow down operations is used as input in a stress analysis program to determine stress, critical sessions evaluation and material recommendations for blow down devices.

    The Belo Monte hydropower plant's low generation cost is among the arguments used by Centrais Eletricas do Norte do Brazil (ELETRONORTE), a Brazilian state electric utility, to make possible its construction. This paper shows that the generation cost presented by ELETROBRAS is very low in relation to the world pattern of cost and probably unrealistic. It also shows that the generation cost cannot be used separately to determine the Belo Monte dam's economic feasibility. There is the need to include other costs, such as: socio environmental degradation and control, financial compensation for using the hydraulic resources, transmission and thermal backup stations, beyond, evidently, generation cost for assuring the credibility of the Belo Monte hydropower plant's economic analysis.

    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.

    The oil industry is one of the more global sectors of the economy, with its economic agents acting and competing at the same time in many countries. The limitation of available funds for investment and competition in global scale make the host countries adapt some elements of their concession instruments, as a way to attract greater investments. The comparison of legal framework of diverse host countries is an essential part in this process of decision and an indispensable tool to help the host countries in the dispute for the attraction of international investors. Therefore, to place Brazil in this process of global competition between States is necessary the knowledge and the comparison between the conditions offered for its legal system and offered for countries considered as models of attraction of investment. This work intends to offer a comparative study of relevant legal aspects for the oil industry, amongst them: characterization of the concession instrument; reach of the participation of the state-owned company; intervention of the State in the private management. The comparison will be made between countries with different characteristics, to obtain a consolidation of paradigms that helps the evolution of the Brazilian exploration and production legal framework.

    Human teeth were analysed by {mu}SRXRF. The measurements were carried out in small areas of the teeth from enamel to root. The aim of this work was to evaluated the local elemental variations in the dental regions, enamel, dentine and pulp from patterns of relative intensities. The distributions of the elements Ca, Zn and Sr were studied. The samples (canine, premolars and molar teeth) were cross-sectioned along the vertical median plane, by polishing the whole tooth in order to obtain a smooth and plane surface, of about 1 mm thick. The measurements were carried out in the XRF beamline of the Synchrotron Light National Laboratory, Campinas, Brazil using a conventional collimation system (orthogonal slits 300 {mu}m x 300 {mu}m). The Ca concentration is quite constant and it is independent of the tooth type and individual characteristics. Ca and Sr distributions show a similar behavior. An increase of the Zn concentration was found for the pulp region and for untreated carious areas. (author)

    The production chain of the oil industry encompasses production systems that operate within different ecosystems. The industry can be split into exploration, production, transportation, refining and distribution, and its importance derives from the influence it has on the nation.s economy. The aim of this study is to provide a holistic view of the different links in the oil production chain, using bibliometric indicators for technological innovation. The methodology employed to analyze the production chain took as its starting point a study of demand, i.e. a characterization of the consumers and identification of the needs and expectations of this consumer market with respect to the products supplied by the different segments of the country.s oil industry. The data was first collected through bibliographical research and a search of specialized databases on the oil production chain in Brazil and worldwide, after which it was analyzed. The result was an identification of the critical competitive factors in the chain, and a tool to assist in the management of the oil industry, to improve its competitiveness and support public and private policy-making. This article is part of a broader study, which will constitute a doctoral thesis. (author)

    The behavior of the ethanol industry in the coming years should be buoyed by several factors, among which gain prominence: feedstock, conversion technologies and products. This article aims, from the analysis of technological road maps, is dealing with Brazil in the face of the global market, is primarily addressing the international context, to assess which technologies tend to predominate, with emphasis on the ethanol industry, addressing convergent and complementary the technology road maps, especially regarding the barriers and challenges, costs and logistics, and other broader issues that govern the production of sustainable feedstock, conversion technologies and biofuels industry, with emphasis on ethanol. Conventional biofuels today are generally not competitive with fossil fuels at market prices, except for the cane ethanol already has a good performance in economic terms. Moreover, strategies for first generation ethanol differ from those for the second generation, which is at an earlier stage of technology development and still subject to comparatively high production costs. The non-economic fundamental barrier to the development of biofuels, particularly ethanol, is the uncertainty as to its sustainability. The debate sometimes on competition with food production and the potential destruction of valuable ecosystems put biofuels in the center of the discussion about sustainability. The challenges facing the ethanol industry range from the need to implement on a large scale to reduce costs along the production chain, through the need for second-generation technologies to reach the level of market, with the behavior of these factors and others will depend on each setting route.

    The aim of this work was to characterize the energy consumption related to the introduction, development, hay processing and storage of Cynodon dactylon (L.) Pers allied to the analysis of the energetic efficiency. The data used in this project were collected from EMBRAPA Gado de Leite, localized in Coronel Pacheco, Minas Gerais, Brazil. The data were obtained from a seven year period of an intensive system of milk production. Energetic coefficients were used to generate the survey and several matrix components obtained from pertinent literature. The direct energy, related to the inputs, showed more efficient participation on the energetic matrix than the indirect energy and the percentages were 94.64 and 5.31, respectively. Farm tractor was the main indirect energy consumer, which is responsible for turning on all the equipment, followed by the irrigation system. The energetic efficiency presented by the whole system was 4.2, being considered positive and demonstrating that the agriculture ecosystem is sustainable. Most of the direct energy employed in this system was oil derived on fuel form. There was, however, a great consume of another oil derived energy such as fertilizer, but mainly on the nitrogen form (28.89% of the total employed energy). (author)

  16. 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)

  17. 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.

    Overcoming another financial crisis, the swine production has the great challenge, in this and next decades, of also reaching the sustainability in the ecosystem ambit. The Parana State/Brazil west area is known because of it's residues high production, with high pollution level, it possesses the added difficulty of presenting high concentration of animals, inserted in production centers in reduced areas. However, this situation reversion, changing the 'trouble called residue' in a 'energy source solution', by means of digesters, became a reality, with the initiative of some producers and researchers. Present work objective was to evaluate the energy production, by means of the digesters use, as alternative energy co-generation. The work was developed at a commercial farm located at the Parana State west area, with 1,700 sows, in an piglet unit producing, with production of 3,400 piglet per mouth. The studied system is constituted by two parallel digesters, with continuous flow and total capacity of 1,275 m3 per digester, with 30 days of hydraulic retention time. The generated biogas feeds a 4.1 cc engine, with six cylinders, 80 cv, 3,600 rpm, coupled to an generator, that constitutes an 50 kW electric engine. The system promoted a 58% reduction of chemical demand of oxygen. The daily gas production estimated was 208 m3, with production of electric energy of 35.2 kWh per day. For most of the year, the system has the potential of provisioning the farm of electricity for all its needs, promoting economy that is transformed into income for the activity. (author)

    Carvalho, H.; Kono, J.; Quintino, M.; Perondi, L.

    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. Current projects are FBM

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.

  2. Familial hypercholesterolemia in Brazil.

    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.

    utilizing the revised scale described by WIDSTROM (27. The data obtained was analised by two different ways. The grades were distributed at first in two different classes: grades 0 and 1 and grades > 2. The grades were afterwards distributed in the following two classes: grades 0 and grades > 1. The chi-square test was applied to verify which of the two types of classes adjusts better with their respective expected ratios. The results showed that when the grades were divided in the classes 0+1 and > 2 the data were more uniform within each treatment. The analysis of variance for each damage class separately, presented F values highly significant for the classes zero and zero plus one, whereas for the classes > 1 and > 2 the damage averages were very similar and the F values were not significant. The class zero plus one had F value higher and the coefficient of variation smaller than the class zero. The ZC 2451 corn compared to the variety IAC Maya XII, exibited good resistance to the corn earworm, under the field conditions of Campinas, State of São Paulo, Brazil. This resistance is of the type non preference and or antibiosis, because there was a higher percentage of ears of ZC 2451 free of earworm damage.

    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

  10. 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

  11. 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

    1999-03-01

    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

    We analyze the electricity distribution segment in Brazil from 1998 to June 2005, trying to assess whether the return on capital invested was in line with the risk and opportunity cost required in the segment. We conclude that the return on capital in this segment in Brazil was systematically negative until 2003. Only in 2005 did the distribution segment really begin to recover, presenting profitability partly consistent with the estimated cost of capital. Comparisons with Argentine, Chilean and American companies reveal that firms in the latter two countries, particularly in Chile, generally managed to reward shareholders according to the opportunity cost of capital. We find evidence of differential effects of regulatory characteristics between the price-cap and cost-plus regimes in the segment's financial profitability, since the return on capital invested was more uniform and predictable in American companies, which are subject to regulation by an internal rate of return or cost-plus mechanism, than in Brazilian firms, subject to price-cap regulation. Among the groups with greater return to profitability after the rationing episode in Brazil in 2002 are EDP Brazil, CPFL Energia, Neoenergia and starting in 2004, Elektro and companies still in government hands. The EDF Group performed the worst in the study period, with negative returns from 1999 onward. (author)

    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

  19. Sexuality education in Brazil.

    Suplicy, M

    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.

  20. 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.

    Full Text Available The present investigation was carried out on a sample of 840 children (5 to 16 years old from ten small towns of the State of Bahia in northeastern Brazil. The objetive was to study, by using a cross sectional methodology, the evolution of schistosomiasis morbidity (hepatic and splenic enlargement in children, and the role of the intensity of S. mansoni infection in this process. The children were analised in three age groups (5 to 8, to 12 and 13 to 16 years old and classified as uninfected, mildly infected, moderately infected and heavily infected according to the number of eggs in the stool. In children aged 5 to 8 years, increasing egg counts were not associated with increasing frequencies of hepatic or splenic enlargement. In the 9 to 12 years old group and association was observed with the prevalence of hepatic enlargement, but not with the prevalence of spleen enlargement. In the oldest group, 13 to 16 years old, an association was observed with the prevalence of enlargement of both organs. It was evident that in this population schistosomiasis morbidity develops in the early period of life as a gradual process starting with liver enlargement and followed by spleen enlargement some years later. It was found that the intensity of infection has a fundamental role in this process, although there is a latent period of some years before clinical splenomegaly appears in moderate-heavily infected children. The Authors suggest that the prevalence of splenomegaly in the 13 to 16 years old group is a good measure of the community level of schistosomiasis morbidity and could be used to measure the impact of control programs.

    Brazil impels its economy again. A development expected in 80 and 90 years it is real. This growth demands new technologies, new researches and bases that bear that growth. Electric power is in these bases, but Brazil is not ready for that. Electric power cogeneration possibility appears, using sugar cane bagasse. Alcohol and sugar plants have already that practice working with a low generation volume. With some investment this volume can be increased, adding about 10% to national energetic matrix. The aim of this work is to present a short time alternative for national electric matrix. It shows the energetic situation of the country, some experiences already implanted in some countries around the world and some options for equipment improvement used in alcohol and sugar plants. It is shown alternatives sources of electric power generation studied on Brazil, as well as the planning of National Energetic Program of ELETROBRAS. It analyses, in details, sugar cane bagasse use, which is used in Sao Paulo plants to generate electric power. Possible systems and troubles for its implantation in sugar and alcohol plants are discussed. (author)

    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

    In nuclear medicine compounds marked with radionuclides, called radiopharmaceuticals, for obtention diagnostic information and for diseases treatment. The physicochemical characteristics of the radiopharmaceuticals determine his fixation at target-organ, and the physical characteristics determine the compound application in diagnostic or therapy. The handling of radiopharmaceuticals generates solid, liquid and gas wastes. The presence of these wastes implies in a adequate management according to regulation standards established by the Brazilian Nuclear Energy Commission (CNEN). The objective of safe management of radioactive wastes is to protect the human being and the preservation of the environment, limiting possible radiological impacts for the future generation, and comprehend a set of technical and administrative activities involved in the collection, segregation, handling, conditioning, transportation, storage, control and elimination, or the final deposition. This work intends to verify if the radioactive waste management systems from the nuclear medicine clinics at the city of Recife are conformal with te normative regulations issued by the CNEN. The initial obtained results are used to elaboration of conformal verification spreadsheet and its application in six nuclear medicine clinics at Recife

    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.

    Currently there are few applications on the risk analysis procedures related to radiotherapy, mainly in the practice of brachytherapy. The objective of this study was to analyze the perception of risk levels, present in the practice of high dose rate brachytherapy (HDR), using a form based on the concept of the risk matrix and a database (SEVRRA) containing information about the processes related to routine brachytherapy. A form containing information regarding the brachytherapy procedure HDR and an attachment indicating how to complete it properly was delivered to a medical physicist of each service/institution. The reference value for the risk levels found, considered acceptable for all performed analyzes, was set at a percentage limit of 33% (assuming a failure in each 3 existing processes). The results showed that the overall risk analysis showed a value for average percentage of prioritized risk of 18% below the recommended range. About the analyzed groups, the higher average percentage of relative risk was found less than 12% of the recommended range, associated with the group of patients. On existing steps, the highest average percentage of relative risk was found less than 1% of the recommended range, associated with stage records and treatment planning. This study showed that although this procedure does not have a large history of accidents, still poses risks considerable that must be managed with great accuracy and immediate action to an effective decrease these risk percentages.

    The objective of this paper is to discuss the possible impacts on the Brazilian economy of an oil shortage crisis and its effects on the domestic market for liquid fuels. The results were obtained from simulations using a multi-sector general equilibrium model. The scenarios used in the numerical experiments were characterized by different constraining levels in imports of crude oil and oil products and also by the ability gasoline may be substituted by fuel ethanol. It is shown that the economic effects depend to a large degree on the substitution flexibility between liquid fuels. Thus it is expected that the introduction of flex-fuel vehicles in the light-duty fleet will make the Brazilian economy much less vulnerable in the event of an external oil-supply shock. (author)

    The Espirito Santo Basin integrates the group of basins along the eastern Brazilian continental margin. It is located between 18 deg and 21 deg S, encompassing an area of approximately 220,000 km{sup 2}, onshore and offshore the Espirito Santo State. Its geological limit with the Campos Basin to the south is defined by a Precambrian basement high (Vitoria Arch), and its northern limit with the Mucuri Basin is defined by a geopolitical limit. The study of salt tectonics processes in the Espirito Santo Basin allowed the deformational analysis and interpretation of the chronological evolution of the mini-basins developed between salt diapirs. We observe an intrinsic relationship between halokinesis and creation of subsidence troughs that may be important for trapping hydrocarbon reservoirs, and consequently form oil and gas accumulations in this portion of the basin. This geodynamics evolution of these structures is marked by a strong linkage between salt movement and coeval sedimentation in the interdomal basins, forming structures and stratigraphic traps that may constitute important aspects for the petroleum geology.

    This document presents the legal and institutional aspects of the environmental licensing for the implementation of small hydroelectric power plants (SHPP). Laws and doctrine related to the topic were researched and concluded for Minas Gerais State with the help of a survey with the enterprises and institutions involved in the process to find out the difficulties that influence the delay of the analysis of the SHPP. It also highlights the importance of environmental zoning as a tool of environmental management for the procedure to obtain these licenses. The results show that 80% of the cases, the institutions do not respect the deadlines, 40% of the studies presented by the enterprises are insufficient, 60% there is lack of human resource and technical capacities of the environment institutions, and 80% non-fulfilment of the laws and non-integration of the institutions. Finally, the study concludes that the difficulties to obtain these licenses are based on the facts mentioned which are, the non-integration of the institutions and also, being recent, on the inexperience of the actors involved. Therefore, it is suggested that deadlines should be imposed for the institutions and the enterprises. There should be training, fund raising for the hiring of technicians, fulfillment of the law and above all, transparency in order to supply the electrical energy demand and guarantee the sustainable development.

    Archaeological ceramics contain infinity of data about social and cultural indigenous site Caninhas/SP. The ceramics present a gradient of color (ochre to dark gray), when from the surface to the center of the piece, indicating compositional variability caused by inefficient sintering carried out by indigenous peoples. It was analyzed the composition phases by X-rays diffraction (XRD) and mapping by EDS, identifying the illite, quartz and lutecite phases (ochre region) and illite, quartz, hydrated alumina and lutecite phases (dark gray region). The results of EDS confirmed the stages identified by X-rays diffraction and suggesting the presence of roots and scrap of ceramics sintered in the composition of indigenous ceramics, when compared by optical microscope and scanning electron microscope. Vickers hardness identified as fragile and heterogeneous are archaeological ceramics, reaching approximately 203 HV in the grains of silica and 16 HV in the ceramic matrix. (author)

    The Pien area presents the major geotectonic domains separated by the Pien Shear Zone (PSZ). The northern one is the Rio Pien Granite-Mylonitic Suite composed by calc-alkaline granitoids of Neoproterozoic age. The southern domain is represented by the Amphibolite-Granulite where high grade metamorphism took place at the end of paleoproterozoic time. Considering the identified lithotypes, their geochemical affinity (particularly the Ti, Cr, Ni and REE content) and the geological context observed in the area, a geotectonical model of active continental margin related to subduction SSZ (Supra-Subduction Zone) is proposed. K-Ar on plagioclase from gabbronorites gave Neoproterozoic ages although Sm-Nd whole rock isochron yielded Paleoproterozoic ages. Based in geochemical data, it is proposed that the biotite gneiss and biotite-amphibole-gneiss which occur near the PSZ have a shoshonitic to high-K calc-alkaline features which are characteristic of active continental margins. K-Ar on biotite extracted from these rocks, gave Neoproterozoic ages. The available radiometric data for the Rio Pien mylonitic granitoids show that between 650-595 Ma the generation, deformation and cooling below the isotherm of 250 deg C occurred. On the other hand, the geochronological data for the Agudos do Sul Massif are in the 590-570 Ma interval showing its younger generation. The Sr{sup 87} / Sr{sup 86} initial ratios for both granitoids suggest more involvement of the continental crust in the origins of Agudos do Sul granitic Massif. The analyses of the entire set of the available data for the Pien area allows the suggestion of a geotectonic scenery related to the evolution of an active continental margin during the collages associated to the Brasiliano Cycle 201 refs., 130 figs., 6 tabs., 2 maps

    The present work was developed in outcrops of Santa Maria region, southern Brazil, Rio Grande do Sul State. Statistic evaluations were applied in different rock types. The possibility to distinguish different geologic units, sedimentary and volcanic (acid and basic types) by means of the statistic analyses from the use of airborne gamma-ray spectrometry integrating potash radiation emissions data with geological and geochemistry data is discussed. This Project was carried out at 1973 by Geological Survey of Brazil/Companhia de Pesquisas de Recursos Minerais. The Camaqua Project evaluated the behavior of potash concentrations generating XYZ Geosof 1997 format, one grid, thematic map and digital thematic map files from this total area. Using these data base, the integration of statistics analyses in sedimentary formations which belong to the Depressao Central do Rio Grande do Sul and/or to volcanic rocks from Planalto da Serra Geral at the border of Parana Basin was tested. Univariate statistics model was used: the media, the standard media error, and the trust limits were estimated. The Tukey's Test was used in order to compare mean values. The results allowed to create criteria to distinguish geological formations based on their potash content. The back-calibration technique was employed to transform K radiation to percentage. Inside this context it was possible to define characteristic values from radioactive potash emissions and their trust ranges in relation to geologic formations. The potash variable when evaluated in relation to geographic Universal Transverse Mercator coordinates system showed a spatial relation following one polynomial model of second order, with one determination coefficient. The statistica 7.1 software Generalist Linear Models produced by Statistics Department of Federal University of Santa Maria/Brazil was used. (author)

    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.

  15. 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.

  16. 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.

    Country economic growth is proportional bond to it electric generation increasing capacity. Brazil, which has a power matrix predominantly renewable, currently is increasing generation, from thermoelectricity, due, mainly, to major facilities in relation to environmental licensing. Since this new Thermal Power Plants operating, tied to the generation with those ones already installed, will result in environmental impacts that must be properly controlled. Such control should follow the Environmental Performance Evaluation guidance, standardized by ABNT NBR ISO 14031/04. Therefore, the following work presents the main Environmental Performance Indicators applied to several thermoelectric generation styles (Oil, Natural Gas, Diesel, Mineral Coal, Biomass, Waste, Solar and Nuclear).

    This article proposes a comparison between photovoltaic and coal fired power plants for electrical energy generation, based on coal reserves in the State of Rio Grande do Sul. Costs associated to the two technologies are compared and considerations are made to costs for prevention and compensation of air, soil and water pollution generated from coal burning, and to funding alternatives with carbon credits that would help the installment of a non pollutant technology. Considering the decreasing trend of the cost of photovoltaic watt, a suggestion for initial financing and limited support is presented, similar to what the European countries make, covering the infant period of the photovoltaic technology in Brazil.

    Full Text Available Na literatura científica, a esporotricose esteve associada por anos a profissionais que lidam com a terra, local onde o fungo causador habita. Recentemente, numa área urbana tem sido registrada a ocorrência relacionada à transmissão zoonótica. Este trabalho objetivou contribuir para o conhecimento sobre a esporotricose em área urbana, por intermédio da analise exploratória de sua distribuição socioespacial no Rio de Janeiro, Brasil, entre 1997 e 2007, identificando os espaços de transmissão mais intensos. Utilizando-se base de dados do Serviço de Vigilância em Saúde, Instituto de Pesquisa Clínica Evandro Chagas, Fundação Oswaldo Cruz, foram realizadas análises de frequência da doença e sua distribuição espacial. No período estudado, foram registrados 1.848 casos de esporotricose, com predomínio em mulheres adultas fora do mercado de trabalho. A fonte de contaminação predominante foi ferimento causado pelo gato doméstico, o que contribuiu para a disseminação da esporotricose em área urbana. O georreferenciamento de 1.681 casos evidenciou um cinturão de transmissão ao longo da divisa entre a capital e os municípios da região metropolitana.In the scientific literature, sporotrichosis has traditionally been associated with agricultural work, since the causative agent is found naturally in the soil.

    The article intends to estimate the direct and indirect emissions of carbon gas through of the Brazilian economy official data and data from the National Energy Balance (BEN), trying to correlate the results. For this, the decomposition methodology will be used by indexes (IDA), accomplishing evaluations in the temporary variations of indicators as: pollution coefficient, energy intensity, effect structures and economical activity. Besides the temporary evaluation of the results considering the available data between 1970 and 2004, the results were compared with other similar studies, whose savings of the studied countries possess relative similarity with the Brazilian economy. The results demonstrated that so in Brazil as in other countries where the methodology was applied was obtained the level of economical growth as main indicator of the CO{sub 2} emissions alterations for each economy. For Brazil, it is also reality, but it is considered in each period by other factors. Another important comparison is in the carbon intensity of each one of the two compared savings. The Brazilian energetic matrix, for their characteristics, propitiates positive impact on carbon emissions results. It also demonstrated that the increase of the participation of the natural gas in the matrix can mitigate the carbon intensity effect, mainly as alternative for the power generation and transport. The use of cleaner fuels and the application of distributed generation and the co-generation energy technologies can be good alternatives for the future and the study of the indexes can help to end which viable and responsible alternatives.

    V and M Brazil is an integrated steel mill for the production of steel tubes. The manufacturing process includes various processes and thermal equipment, such as industrial furnaces, boilers, and others. Due to its importance, it is essential that these devices operate with the best possible efficiency. Thus, it becomes necessary to use tools and methods for performance analysis of energy processes that occurs on these devices. One tool that has been widely used in industrial environment is the exergy analysis. It is based on the Second Law of Thermodynamics, and therefore takes into account the entropy generation, indicating the maximum amount of useful energy (work) that can be drawn from a stream, with reference to environmental parameters. This paper aims to apply the exergetic methodology in industrial thermal processes that occurs at V and M Brazil, as a tool for identification of losses and potential performance improvement of energy systems to save on fuel and the reduction of environmental impacts and emissions of greenhouse gases.

    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)

  8. 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.

    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

    Taking into account the global importance of the petroleum industry, the present work aims to present a study of this industry through the lens of its production chain, using bibliometric indicators of technological innovation in order to determine critical competitiveness factors. The concept of the production chain includes the set of activities undertaken progressively from raw material to the final product, including distribution and sales, with each segment being a link in the chain. The petroleum industry is composed of a production chain which may be divided into the following segments: exploration and production, transportation of crude oil and natural gas, refining, transportation of derivatives and distribution. The development of the present work involved the analysis of information about the petroleum production chain in Brazil and elsewhere, gathered through research in specialized database. The analysis of bibliometric indicators of technological innovation in each link of the production chain maps the technological trends existing in this chain. (author)

    This work aims analyze the constraints to the introduction of LNG in the Brazilian energy matrix. Therefore, considers the current regulatory framework and the investments recently made by PETROBRAS to acquire LNG in the international market in order to supply power plants in the country. In order to assess the current status of the LNG plants in the electricity sector, factors are analyzed in terms of the natural gas industry and electric power industry, such as: storage, LNG contracts, operating dispatch, LNG plants pricing and operational flexibility. Despite the increase in LNG international trade and the prospect of using this product in Brazil, there are some challenges for the effective use of LNG plants by Brazilian electric sector. Some of the challenges are the need to review the methodology of calculating the cost benefit of LNG power plants. Another important challenge is to examine the use of underground storage and its influence in the operating dispatch of LNG plants. (author)

  17. Brazil: World Oil Report 1991

    International Nuclear Information System (INIS)

    This paper reports that Brazil's state oil company Petrobras has racked up a significant period of achievement over the last 12 months. Average daily oil production hit a new high. A small portion of deepwater giant Marlim field came onstream. Risk contracts ended, and the firm assumed all responsibility for exploration activity in Brazil. Furthermore, Santos basin proved to be the nation's most recent oil province after two discoveries. Last, but not least, Petrobras assumed a dominant position worldwide in development of new deepwater technology, as evidenced by papers presented at the 1991 Offshore Technology Conference. What is remarkable is that all this was achieved while the company was experiencing political turmoil. Last Oct. 19, Petrobras President Luis Octavio Motta Veiga resigned in a dispute with the Ministry of Economy (MOE) over refined product pricing levels. His replacement, interestingly enough, was the 36-year-old executive secretary of the MOE, Eduardo de Freitas Teixeira. His term at Petrobras lasted less than six months

    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)

    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

  20. Homosexuality and adoption in Brazil.

    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

    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)

  13. 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

    D' Abbadia, Martinho Romulo Iria

    1999-02-01

    This work presents some thicknesses estimates in overlapped sedimentary sections. The adopted procedure consists of the accomplishment of kriging followed by weighed corrections that provide mathematical consistency to the operation of thicknesses addition. These weighed corrections are based on the proportions between: the thicknesses of the estimated layers and the total thickness of the analyzed section; the standard deviation of the estimation error and the addition of these standard deviations; the variance of the estimation error and the addition of these variances. The proposed method is characterized by its simplicity and operational flexibility, being distinguished by: the number of intervals to be analyzed is theoretically limitless; stationary thicknesses are not required; choice of distinct neighborhoods for each analyzed interval is allowed; it has freedom for the use of distinct models in each investigated interval, making it possible to choose different functions, amplitudes and anisotropies. The technique was applied in an oil field situated in the northeast of Brazil, helping in localising the preferential depositional areas for turbiditic reservoirs and allowing inferences with respect to structural aspects of studied area.

    The electric sector went through deep changes along these 125 years of electrification of the country, mainly the alternation of their investment bases, hour being private for the most part, state hour. The legal bases of concession and regulation also varied in this period, trying to adapt to the effective model of the time. This work intends to analyze the evolution of the regulatory models of the electric sector, identifying the main changes of paradigms and to compare the efficiency of the models already implanted in the segment, with views to the increment of the offer of energy in the period, molding a critical profile of the best model already adopted in the national electric sector. To compare qualitatively these models requests an analysis of the investment bases a priori in the sector, identifying the contribution of resources has been private or state, following by the government's legal positioning in the sense of being only regulator, or regulator and investor, concluding with an analysis of the electric power offer in the period and the power of self-financing of the companies, in order to assent that the mixed model is the most appropriate model for the sustainable growth of the electric power generation sector in Brazil.

    There is a great global concern about the depletion and the high cost of fossil fuel reserves exploitation, more than ever, it is necessary to make a profound study and take advantage of alternative sources that can be used as energy efficiency with an appropriate pricing and low environmental impact. Brazil, which has highlighted using alternative energy sources as the use of ethanol and, in recent years, has been encouraging the expansion of its energy matrix in which the biodiesel will have a strategic importance within the agrobusiness area. Biodiesel is a fuel that can replace the diesel, which is a petroleum derivative. It is an ester, produced in the transesterification reaction of vegetable oils and animal greases, in an alcohol with an additional catalyst, are converted into fatty acids and result in esters with glycerol as sub products. The objective of this study was to estimate the final energy balance for the process biodiesel production from oil chicken waste. The energy balance estimation was quantified in calorific value according to the energy expenditure by calorimetric bomb method. The relationship between input and output of energy was around 0.97. In a first evaluation, the procedures adopted should be improved enough, so the process can become energetic and economically viable. (author)

    Energy Technology Data Exchange (ETDEWEB)

    Armelin, Maria Jose Aguirre

    1978-07-01

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

    The awareness of the importance of the environment has stimulated the study of new renewed energy sources and less pollutant. Amongst these sources, solar energy stands alone for being perennial and clean. The use of solar energy in systems of agricultural residential water heating, can complement the economy of electric energy, base of the Brazilian energy matrix. Knowing the factors that influence the operation of a system of water heating by solar energy is important in determining their technical viabilities targeting their distribution in agricultural residences. To evaluate equipment of water heating for solar energy, a prototype was constructed in the campus of Assis Gurgacz College, in Cascavel,State of Parana, Brazil, with similar characteristics to equipment used in residences for two inhabitants, to function with natural circulation or thermo siphon and without help of a complementary heating system. The equipment revealed technical viability, reaching the minimum temperature for shower, of 35 deg C, whenever the solar radiation was above the 3,500 Wh m{sup -2}, for the majority of the studied days.

    Decision analysis applied to the development phase of petroleum fields must take into account the risk associated to many kinds of uncertainties. In the transition of the appraisal to the development phases, the importance of risk associated to the production and the recovery factor may increase significantly. The process is complex due to high investments, large number of uncertain variables and strong dependence of the results with the production strategy definition. In E and P, several decisions must be taken considering the risks involved through the appraisal of the uncertainties impact in production of petroleum fields, increase the possibility of success, measuring possible lost and sub-optimized developments identifying new opportunities. In a specific scenario, like gas production, the risk associated to the project becomes larger due to the gas prices compared to oil, the demand, the distribution's structure and the deadlines defined in contracts. The objective of this paper is to show the results of a methodology developed in a detailed study of a risk analysis process in appraisal and development phases (execution and implementation) to one of the biggest gas fields in Brazil (Mexilhao Field) and support reliable future decisions.

    The National Commission of Nuclear Energy (CNEN) is responsible in Brazil for the activities of licensing and control of radioactive installations in the radiotherapy medical area. The majority of these activities are developed by CNEN Co-ordination of Radioactive Installations (CORAD). One of the necessary stages for the development of licensing and control activities is the inspection of radiotherapy services (clinics and hospitals). Almost all of these inspections are carried out by CNEN Inst. of Radiation Protection and Dosimetry (IRD), through its Service of Medical Physics in Radiotherapy and Nuclear Medicine (SEFME). This work makes a survey of the main nonconformities found during ten years of inspections in radiotherapy services (1995 - 2004) and analyses the efficiency of these inspections in making the radiotherapy services develop their activities according to the norms in vigour in the country and adopt corrective actions against, at least, the nonconformities evidenced by CNEN inspectors. Additionally, it analyses the possibility of improvement and / or the optimisation of the process, through a procedure able to be unified and controlled, aiming a prompt communication to those involved in the licensing process (SEFME and CORAD) about the attendance by the radiotherapy services to the non-conformity items observed during the inspection.

    The oil exporting countries can be vulnerable to this row-material as the oil importing ones, due to their social economic dependence of the revenues generated by the oil and gas sector. So, it is also important for those countries the analysis of their social economic vulnerability in order to contribute for the comprehension of their real actions related to their production strategies, aiming to affect oil price and market-share. Due to that, this thesis proposes a methodology based on social economic indicators of oil exporting countries, which will enclose the following aspects: physical, productive, commercial, macro economic, fiscal and social. These indicators will be applied to the OPEC members, Norway and Mexico, and orientated through a normalized scale as in a multicriteria methodology (AHP - Analytic Hierarchy Process). The analyzed results will drive the social economic implications, and the studied countries will be classified in a scale that goes from very favorable to very unfavorable. The results point the main social economic fragilities of the oil exporting countries, designing pathways to Brazil and their possible exporting ambitions. The most important considerations that became from the vulnerable oil export countries experiences refers to the necessity to straight and increases their macro economic foundations, industrial diversification incentives and the creation of an stabilization fund (based on oil revenues) for the future generations, or to severe oil prices oscillations periods in the international market (author)

    Natural circulation loops apply to many engineering applications such as: water heating solar energy system (thermo-siphons), thermal management of electrical components (voltage converter), geothermal energy, nuclear reactors, etc. In pressurized water nuclear reactors, known as PWR's, the natural circulation loops are employed to ensure passive safety. In critical situations, the heat transfer will occur only by natural convection, without any external control or mechanical devices. This feature is desired and has been considered in modern nuclear reactor projects. This work consists of a numerical study of the natural circulation loop, located at the Instituto de Pesquisas Energeticas e Nucleares / Comissao Nacional de Energia Nuclear in Sao Paulo, Brazil, in order to establish the flow pattern in single phase conditions. The comparison of numerical results to experiments in transient condition revealed significant deviations for the Zero Equation turbulence model. Intermediate deviations for the Eddy Viscosity Turbulence Equation (EVTE), k - {omega}, SST e SSG models. And the best results are obtained by the k - {epsilon} e DES models (with better results for the k - {epsilon} model). (author)

    The natural gas pipeline network grows around the world, but its operation inherently imposes a risk to the people living next to pipelines. Due to this, it is necessary to conduct a risk analysis during the environmental licensing in Brazil. Despite the risk analysis methodology is well established, some points of its application for the distribution pipelines are still under discussion. This paper presents a methodology that examines the influences of major projects and operating parameters on the risk calculation of a distribution pipeline accident in urban areas as well as the possible accident scenarios assessment complexity. The impact of some scenarios has been evaluated using a Computational Fluid Dynamics tool. The results indicate that, under certain conditions, the risks from the pipeline operation under operating pressures of 20 bar may be acceptable in location class 3 or even in class 4. These results play a very important role if management decisions on the growth of the distribution of natural gas network in densely populated areas as well as in the improvement of laws to control the activity of distribution of natural gas.

    2011-07-01

    This work has implemented a methodology for automation of images analysis of chromosomes of human cells irradiated at IEA-R1 nuclear reactor (located at IPEN, Sao Paulo, Brazil), and therefore subject to morphological aberrations. This methodology intends to be a tool for helping cytogeneticists on identification, characterization and classification of chromosomal metaphasic analysis. The methodology development has included the creation of a software application based on artificial intelligence techniques using Fuzzy Logic combined with image processing techniques. The developed application was named CHRIMAN and is composed of modules that contain the methodological steps which are important requirements in order to achieve an automated analysis. The first step is the standardization of the bi-dimensional digital image acquisition procedure through coupling a simple digital camera to the ocular of the conventional metaphasic analysis microscope. Second step is related to the image treatment achieved through digital filters application; storing and organization of information obtained both from image content itself, and from selected extracted features, for further use on pattern recognition algorithms. The third step consists on characterizing, counting and classification of stored digital images and extracted features information. The accuracy in the recognition of chromosome images is 93.9%. This classification is based on classical standards obtained at Buckton [1973], and enables support to geneticist on chromosomic analysis procedure, decreasing analysis time, and creating conditions to include this method on a broader evaluation system on human cell damage due to ionizing radiation exposure.

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

    The large field patterns in this view of the Rio Sao Francisco basin, Brazil, South America, (11.5S, 43.5W) indicate a commercial agriculture venture; family subsistence farms are much smaller and laid out in different patterns. Land clearing in Brazil has increased at an alarming rate in recent years and preliminary estimates suggest a 25 to 30% increase in deforestation since 1984. The long term impact on the ecological processes are still unknown.

    The reported events in radiotherapy that constitute accidents or incidents have increased worldwide in the last 25 years. Most of these events resulted from human failure and have happened in radiotherapy centers that use high technologies. The radiotherapy Quality Management needs a prospective approach through risk analysis. This approach is supported by recent publications as this actually extremely needed due the large number of accidents. Because of the complexity of the process in radiotherapy, the search for quality of care in order to ensure patient safety is one of the most discussed topics worldwide. Although only 14% of radiotherapy centers in Brazil offer treatments with intracranial radiosurgery technique (SRS), studies about the quality of care related to the safety of patients undergoing this technique is of great importance. Any deviations from the prescribed dose using SRS technique is considered more critical than in other methods of radiation treatment, as the delivered doses in SRS are higher, in the range of 10 Gy to 40 Gy, to lesions up to 50 mm in diameter, which are delivered in a single fraction or in five fractions. In view of those information, this work aims to satisfy the new Quality Management paradigm by developing a risk analysis model, and a Quality Index for SRS in Brazil, through the techniques of Process Map and FMEA used in the TG100/AAPM. The study was performed in three high technology reference radiotherapy centers, two located in Rio de Janeiro city and one in Sao Paulo city. A SRS Process Map was identified for each radiotherapy center, and then FMEA technique was applied in every subprocesses identified on the map. >From NPR values obtained by the FMEA a ranking of failure modes was held. Failure modes with NPR ≥ 100 and S ≥ 7 were chosen as priority to implement safety strategies. From the scores assigned to the S parameter in the implementation of FMEA a Severity Index (SI) and a Quality Index (QI) were created from

    Many of hydrocarbon reserves existing in the world are formed by heavy oils (deg API between 10 and 20). Moreover, several heavy oil fields are mature and, thus, offer great challenges for oil industry. Among the thermal methods used to recover these resources, steam flooding has been the main economically viable alternative. Latent heat carried by steam heats the reservoir, reducing oil viscosity and facilitating the production. This method has many variations and has been studied both theoretically and experimentally (in pilot projects and in full field applications). In order to increase oil recovery and reduce steam injection costs, the injection of alternative fluid has been used on three main ways: alternately, co-injected with steam and after steam injection interruption. The main objective of these injection systems is to reduce the amount of heat supplied to the reservoir, using cheaper fluids and maintaining the same oil production levels. In this paper, the use of N{sub 2} as an alternative fluid to the steam was investigated. The analyzed parameters were oil recoveries and net cumulative oil productions. The reservoir simulation model corresponds to an oil reservoir of 100 m x 100 m x 28 m size, on a Cartesian coordinates system (x, y and z directions). It is a semi synthetic model with some reservoir data similar to those found in Potiguar Basin, Brazil. All studied cases were done using the simulator STARS from CMG (Computer Modelling Group, version 2009.10). It was found that N{sub 2} injection after steam injection interruption achieved the highest net cumulative oil compared to others injection system. Moreover, it was observed that N2 as alternative fluid to steam did not present increase on oil recovery. (author)

    The solar water heating is carried through, in Brazil, by means of solar heaters compound for collectors flat plate of the type plate-and-pipes, devices that operate in stationary position and they do not require tracking of the sun. A compound collector for some formed V-trough concentrators can be an alternative to the conventional solar collectors flat plate. This compound collector for V-trough is considered, each one, for side-walls which are specularly reflecting surfaces associates in V (equivalent to a triangular gutter). Next to the vertex to each V-trough concentrators an absorber tube is fixed, for flow of the fluid to be heated. Interconnection of the absorbers tubes forms a similar tubular network existing in solar collectors of the type the plate and pipe. V-trough concentrators with the absorbers tubes are made use in series in the interior a prismatic box, which have one of its faces consisting by a glass covering and directed toward incidence of the solar radiation. An analysis of thermal performance of these devices operating stationary and without tracking of the sun is researched. A mathematical model for the computational simulation of the optical and thermal performance of these concentrative devices is elaborated, whose implementation was carried through software EES (Engineering Equation Solver). The efficiency optics of V-trough concentrators with cylindrical absorbers is calculated from the adaptation of the methodology used for Fraidenraich (1994), proposal for Hollands (1971) for V-trough cavities with plain absorbers. The thermal analysis of the considered collector was based on the applied methodology the CPC for Hsieh (1981) and Leao (1989). Relative results to the thermal performance of V-trough concentrators suggest that these configurations are not competitive, technique and economically, with the conventional plain collectors. Although some geometric configurations presented next thermal efficiencies to the conventional plain

    2011-01-01

    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.

  7. Light, distribution company in Brazil

    International Nuclear Information System (INIS)

    Since the publication of the Roulet Report, Electricite de France (EDF), the French group is crossing tormented hours. 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)

    This paper describes a joint US/Brazil pilot project for rural electrification, whose major goals are: to establish technical, institutional, and economic confidence in using renewable energy (PV and wind) to meet the needs of the citizens of rural Brazil; to establish on-going institutional, individual and business relationships necessary to implement sustainable programs and commitments; to lay the groundwork for larger scale rural electrification through the use of distributed renewable technologies. The projects have supported low power home lighting systems, lighting and refrigeration for schools and medical centers, and water pumping systems. This is viewed as a long term project, where much of the equipment will come from the US, but Brazil will be responsible for program management, and sharing data gained from the program. The paper describes in detail the Brazilian program which was instituted to support this phased project.

  13. 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.)

  14. 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.

    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

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)

    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)

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.

  19. 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

  20. 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.

  8. Ethnozoology in Brazil: current status and perspectives

    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.

  11. 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

  12. 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

  14. 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.

  1. 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)

    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.

  5. 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)

    This paper analyzes the relation between international liquidity and growth for Brazil in 1966-2000. Defining the former as the ratio of foreign reserves to foreign (interest-bearing) debt, the objective is to build a model connecting growth with international liquidity, and then check whether the results from such a model hold up in practice. The model builds upon Thirlwall's (1979) law and uses some basic accounting identities to specify a liquidity constraint on small open economies. The m...

    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

These graduates are prepared to work in industry, research institutes and universities in areas of knowledge involving Biochemistry and Molecular Biology. This is happening in developed countries since the first half of the last century, surprising and late is the implementation of bachelor of Biochemistry in Brazil. OBJECTIVES: The aim of this study was to perform a comparative analysis of the Bachelor in Biochemistry in Brazil from the perspective of the main difficulties of implementing and courses maintenance. 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

    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

  20. 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

  2. Review of plant biogeographic studies in Brazil

    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.

  3. 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.

  5. Noise in large cities in Brazil

    Gerges, Samir N. Y.

    2001-05-01

    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.

    Carvalho, Maria da Gloria Pires de; Ponciano, Luiza Corral Martins de Oliveira

    2015-12-01

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

    The electric power sector reformulation implemented in the Brazil makes evident the intrinsic difficulty to handle with complex set of veto players. The multiplicity of veto players characterized by distinct ideologies results in the multiplication of business rounds related to the elaboration and implementation of the new game rules, whose agreement involves conflicts on the presented proposal, resulting in the slowness pf reformulation process conclusion.

    Brazil is the world's greater producer of charcoal and most of this production takes care of to the siderurgical sector. Thus, one understands that the Brazilian steel is produced of sustainable form. However, such sustainability is not based only on a renewable energy source. The origin of the wood for the carbonization, if proceeding from planted forests or native bushes, is crucial factor in this analysis. Beyond the ambient dimension, the sustainability of the charcoal segment also is influenced by its social, economic and technological aspects. In this context, the present article searches, through the construction and the analysis of the diagnosis of the charcoal in Brazil, to evaluate the sustainability of the sector and to consider alternatives to reach it. The current model of production of charcoal in the country is unsustainable. The main adopted systems of carbonization in Brazil are low level technological with consequent decrease production. The activity is unhealthy, beyond having many cases of enslaved and infantile work. The coal of native forests is much cheaper and the fiscalization is poor, fact that discourages its production from planted forests. But if the vegetal coal will be understood as an energy solution for the siderurgical sector measures can be taken to search a model of sustainable production. (author)

  14. The problems of nutrition in Brazil.

    Sanders, T G

    1982-01-01

    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

    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.

    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.

    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.

    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.

  14. 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.

    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

  19. Uranium exploration in Brazil and its results

    International Nuclear Information System (INIS)

    The development of the works of prospecting and exploration of uranium in Brazil since 1952 is described in its principal phases: the descovery of the first uranium indications in Pocos de Caldas and Jacobina; the technical cooperation agreements with the United States Government in 1955; the action of CNEN, in 1962, through its Mineral Exploration Department; the increasing of financial resources in the 70's; the foundation of NUCLEBRAS in 1974 and (within the agreement with the FRG) of its subsidiary NUCLAM, in association with'Urangesellschaft'. The evolution of the investments and of the number of technicians involved in these different phases is shown. (I.C.R.)

  20. A Central Brazil GT5 Event

    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

  1. 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)

  2. 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

    We analyse the acceleration of a mass with a simple structure taking into account Thermodynamics. Two situations are analysed. The first one for the application of a localized force to a point of the mass. The second one for the application of a force to the entire mass. The two situations are not equivalent. For the first situation we have an increase of temperature of the mass, resulting from an internal damping, during a transient.

    Full Text Available All too often literary structures in the New Testament are passed off in scholarly literature as mere literary niceties serving only aesthetic ends. Too little consideration has been given to the possible exegetical signif­ icance of such structures to the interpretation of biblical texts. This article is an attempt to present an apologetic for the value of stylistic analysis of New Testament texts as an aid in interpreting the New Testament. It must be kept in mind that to the biblical authors, artistry in the use of stylistic structures was not an end in itself, but a means towards more effective communication of the message.

    An analysis of the institutional evolution of the governmental organizations which were responsible for the regulation of the electrical energy sector in Brazil (before the establishment of the ANEEL) is presented . Taking into account the various levels of subordination and independence in their actuation, the different missions and powers given to these agencies regarding the inspection, controlling, planning and regulating the industry, are compared and discussed. The conducted analysis is essentially formal, based on the legal instruments which defined and established the creation of those agencies. (author)

  11. 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

    2015-11-01

    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

    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

  20. 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.)

  1. 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.

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.

  4. 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.

  5. 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.

  6. News and views: nuclear power in Brazil

    International Nuclear Information System (INIS)

    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.

    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.

    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.)

    1997-01-01

    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

  10. 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.)

  11. 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

  12. 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

    Eleven institutions of education and research in Brazil use particle accelerators, which fulfill different functions and activities. Currently, these institutions employ a total of fifteen accelerators. In this paper, the object of study is the radiological protection of occupationally exposed individuals, the general public and the radiation safety of particle accelerators. Research facilities with accelerators are classified in categories I and II according to the International Atomic Energy Agency or groups IX and X in accordance with the Brazilian National Commission of Nuclear Energy. Of the 15 accelerators in use for research in Brazil, four belong to category I or group X and eleven belong to category II or group IX. The methodology presented and developed in this work was made through the inspection and assessment of safety and radiological protection of thirteen particle accelerators facilities, and its main purpose was to promote safer use of this practice by following established guidelines for safety and radiological protection. The results presented in this work showed the need to create a program, in our country, for the control of safety and radiological protection of this ionizing radiation practice. (author)

    The Brazilian cement industry produced 64 million tons of cement in 2012, with noteworthy contribution of CP-II (slag), CP-III (blast furnace) and CP-IV (pozzolanic) cements. The industrial pole comprises about 80 factories that utilize raw materials of different origins and chemical compositions that require enhanced analytical technologies to optimize production in order to gain space in the growing consumer market in Brazil. This paper assesses the sensitivity of mineralogical analysis by X-ray diffraction associated with cluster analysis to distinguish different kinds of cements with different additions. This technique can be applied, for example, in the prospection of different types of limestone (calcitic, dolomitic and siliceous) as well as in the qualification of different clinkers. The cluster analysis does not require any specific knowledge of the mineralogical composition of the diffractograms to be clustered; rather, it is based on their similarity. The materials tested for addition have different origins: fly ashes from different power stations from South Brazil and slag from different steel plants in the Southeast. Cement with different additions of limestone and white Portland cement were also used. The Rietveld method of qualitative and quantitative analysis was used for measuring the results generated by the cluster analysis technique. (author)

  18. 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.

    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

  5. 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.

  6. 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

  7. 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

  8. 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.

    Eliassen, H. [StatoilHydro, Trondheim (Norway)

    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...

  12. 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)

  13. 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

  19. 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.

  20. 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.

  1. Niobium (columbium) and tantalum resources of Brazil

    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. Ore reserves of the Barreiro deposit in all categories are 380 million tons with percent Nb2O5. Annual production of tantalite-columbite from the Sao Joao del Rei district, most of which is exported to the United States, is about 290 tons, of which about 79 percent is tantalite and about percent is columbite. Reserves of tantalite-columbite in the Sao Joao del Rei district are about 43,000 tons of proved and 73,000 tons of probable ore.

  2. Misoprostol and illegal abortion in Fortaleza, Brazil.

    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

  9. 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)

  10. 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

  11. 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

    The sugar industry goes through an important moment: invest and develop to supply future demand, mainly by fuel alcohol (around 70% of new vehicles sales are from flex fuel models - and the majority of these vehicles are supplied by alcohol). Due to this foreseeable increase of alcohol demand, sugar industry has already announced 41 new projects, which will contribute with the milling of 70 million tons of sugar cane by the conclusion of these plants. In this phase of expansion, the alcohol market must be pressured for the demand, managing the supplying of the domestic and external markets. With this scenario and the possibility of sector growth which has an important role in Brazil development, this work evaluates the economic impacts of the new plants implementation investments.

  14. 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

    Abstract Background Caesarean section rates in Brazil have been steadily increasing. In 2009, for the first time, the number of children born by this type of procedure was greater than the number of vaginal births. Caesarean section is associated with a series of adverse effects on the women and newborn, and recent evidence suggests that the increasing rates of prematurity and low birth weight in Brazil are associated to the increasing rates of Caesarean section and labour induction.

    Increasing demand for biofuel has intensified land-use change (LUC) for sugarcane (Saccharum officinarum) expansion in Brazil. Assessments of soil quality (SQ) response to this LUC are essential for quantifying and monitoring sustainability of sugarcane production over time. Since there is not a universal methodology for assessing SQ, we conducted a field-study at three sites within the largest sugarcane-producing region of Brazil to develop a SQ index (SQI).

  3. Space Radar Image of Bebedauro, Brazil, seasonal

    1994-01-01

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

    Siqueira, F.; Pinheiro, K.; Linthe, H.

    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

  6. 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

  7. Origin and evolution of dengue virus type 3 in Brazil.

    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.

    The production and the supply of high quality laboratory animals have fundamental importance for the accomplishment of vanguard scientific research, with reproducibility and universality. The quality of those animals depends, largely, of the available facilities for their production and lodging, to assure the demanded sanitary control and animals' welfare, in agreement with the ethical principles that control the activity. The facilities also have to fill out other requirements, such as: the functionality of the environments to make possible the suitable and efficient handling of the animals, facilitating the execution of the routine activities; the respect to ergonomic principles to provide a safe environment and the operators' well being. The facilities design is of vital importance so that the mentioned requirements can be reached. The project of the Nuclear and Energy Research Institute (IPEN) Animal House Facilities was accomplished in the year of 1964. However, by that time there were not the current recommendations with respect to the sanitary, genetic and environmental controls. The facility was planned with the objective of being a production unit and a local for keeping of defined animals from sanitary, genetic and environmental point of view. Nevertheless, the original unit drawing presents an unsuitable distribution of the area where animals are stocked and also different activities are performed. The Animal House Facilities occupy an area of 840 m2, with one pavement, where the production areas and the stock of original animal models of the own Institution are distributed, as well as the maintenance of animals from other national or foreigner institutions. It supplies rats and mice for biological tests of radiopharmaceutical lots, produced in IPEN, before they be sent to hospitals and clinics spread out in Brazil, for use in Nuclear Medicine. It also supplies rats and mice for tests of dental materials, for tests with growth hormones and for

    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.

  14. 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.

    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.

    Luís A. B. Cortez

    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.

    2013-01-01

    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.

  1. Biosorption of uranium by Azolla, SP, Brazil

    International Nuclear Information System (INIS)

    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.

    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.

  3. 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)

  4. 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.

  6. 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''

  7. 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

  8. 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.

    Full Text Available ABSTRACT: Objectives: Vaccines represent an important advancement for improving the general health of a population. 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.

    2011-12-01

    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.

  12. 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)

  13. 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

    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.

    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.

    This work has the objective to analyze the impact of the cost of from an ethane reformer / fuel cell in the family income considering the development of two productive activities selected by the community itself: the production and marketing of cassava flour and 'rapadura', a typical brazilian candy. The community energy demand was analyzed to achieve the results; estimated the energy cost from the implemented system and the money from the selling of the cassava flour and 'rapadura' produced with this electricity; the study of sensibility of the ethanol price in the electrical energy cost was done too, and the cassava flour and 'rapadura' in the family funds. From the results, it was verified that the electrical energy cost has a 16,4% impact in the family gross income and a net value around R$ 260,85/family, indicating that the community will have enough funds to pay for the energy and also will rise the amount of money for each family. Besides, the comparative analyze of the cost of the electricity from the ethanol/fuel cell reformer and photovoltaic systems shows that, considering only the maintenance and operation costs, the first one should be more attractive than the second one.

    With the increasing of energetic demand in several production sectors, the search for renewable energy sources which do not cause negative environmental impacts has become more and more relevant. Amongst all the important factors to decide for installing isolated generation systems as renewable sources or diesel and taking the distribution network to isolated communities, it should be considered the economic viability of those benefits. This study aimed to analyse the hybrid solar-aeolian system installed in an isolated community, in Jalapao/TO. Three scenarios were analyzed: first of them, getting the capital back with MRI = 6% per year; second one, getting the capital back with MRI = 0; and third, without getting the investment back. In all the three cases, O and M costs were considered. The proceeds were calculated from the production at the community workshop, in which the electricity was available. The results indicated that this technology is economically viable if the generated energy is used for production process. It also demonstrated that the third scenario is more interesting for the community, since the contribution per family is only 8% of its incomes. (author)

    The wind energy is an abundant source of renewable energy, clean and available almost everywhere. For its use, studies are needed to adequately describe its intensity for statistical methods and design for wind turbines. The objective is to structure the mathematical methods used to conduct a general description of the wind, to establish a description of the wind regime using the parameters described using the Weibull function and the analytical model of power from a wind turbine, as well as applications of these methods show. This work was developed at Rural Empowerment Lab of FCA/UNESP in Botucatu-SP. For the application of methods were utilized measurements of wind speed and direction, between 2004 and 2005, obtained by anemometer RM Young Wind Monitor-Campbell. As a result, they estimated the wind behavior and distribution of wind in the region, with 78 kWh of energy production, relatively low potential to supply a small house. Moreover, this energy could possibly be applied in ambient illumination, power supply for electric fences and irrigation of vegetables. (author)

    This article aims to analyze the potential application of integrated management, through concepts of SCM (Supply Chain Management), in the chain of the energy industry, which is characterized by a chain of services. The prospect of incorporating new integrated management practices, through the selection of concepts and tools for supply chain management took the possibility of promoting systemic approach that includes the major components (physical, regulatory and commercial) the market of electric energy, investigating possibilities of reorganization of this important segment of the industry production chain. The proposal aims to provide a tool for planning indicative of great potential, to identify a theoretical reference in this important productive sector. The work includes qualitative analyses, which aim to map, understand and systematize the changes undertaken, with emphasis on Brazilian electric sector. It is described, in general, the characterization of the energy industry in Bahia state as a possible case study in implementing the proposed methodology. Thus, the work seeks to help the staff decision to purchase a minimum of integrated vision of possible decisions, including the dynamic interactions between market supply and demand. (author)
