    In this work the concentrations of natural radionuclides {sup 226}Ra, {sup 232}Th and {sup 40}K were determined in superficial sand samples for 16 locations throughout the coast of the Great Victory, metropolitan region of the state of Espirito Santo, Southeast of Brazil. The assessed beaches were Manguinhos and Jacaraipe in Serra county, Camburi, Praia do Canto and Curva da Jurema in Vitoria county, Praia da Costa and Itapua in Vila Velha county, Setibao, Setibinha, Praia do Morro, Praia das Castanheiras and Areia Preta in Guarapari county and sand of the Paulo Cesar Vinha Reserve also located in Guarapari county. Three sand samples of each beach were sealed in 100 mL high density polyethylene flasks. After approximately 4 weeks in order to reach secular equilibrium in the {sup 238}U and {sup 2}'3{sup 2}Th series, the samples were measured by high resolution gamma spectrometry and the spectra analyzed with the WinnerGamma software. The self absorption correction was performed for all samples. The {sup 226}Ra concentration was determined from the weighted average concentrations of {sup 214}Pb and {sup 21}'4Bi, the {sup 232}Th concentration was determined from the weighted average concentrations of {sup 228}Ac, {sup 2}'1{sup 2}Pb and {sup 212}Bi and the concentration of {sup 40}K is determined by its single gamma transition of 1460 keV. The radium equivalent concentration and the external hazard index where obtained from the concentrations of {sup 226}Ra, {sup 232}Th and {sup 4}'0K. {sup 226}Ra concentrations show values varying from 3 +- 1 Bq.kg-1 to 738 +- 38 Bq.kg{sup -1}, with the highest values for the central locality of the Camburi beach. {sup 232}Th concentrations show values varying from 7 +- 3 Bq.kg{sup -1} to 7422 +- 526 Bq.kg{sup -1}, with the highest values for Areia Preta beach. {sup 40}K concentrations show values varying from 14 +- 6 Bq.kg{sup -1} to 638 +- 232 Bq.kg{sup -1}, with the highest values for Areia Preta beach

    Currently in Brazil (2016), there are 421 Nuclear Medicine Services (NMS). In nuclear medicine, the possibility of occupational internal contamination and external exposure is unavoidable. The chest individual monitoring, to estimate the effective dose, is mandatory, but the extremity monitoring is not always made. The aim of this study was to conduct a survey of data for external exposure of NMS professionals in Brazil from 1987 to 2010, analysing them in terms of trends and comparing them with measurements carried out in this work and in other countries. Although most of the NMS is still located in large urban centres (54% in the Southeast region), there is no state without any NMS. The increasing number of NMS has generated the need for more professionals. In the year 1987, they were 755 workers and, in 2010, 4134, with the following distribution of specialties: 29% of Nuclear Medicine Technicians (NMT), 23% of Nursing professionals, 29% of Physicians and 3% of Physicists. The average annual effective dose reached more than 3.0 mSv in some regions of the country, from 1987 to 2010, but tends to 1.0 mSv in 2010. The highest doses, as expected, are received by NMT and Nursing. The professionals who handle radiopharmaceuticals have their hands much more exposed than the chest. During 2010, only 31% of NMT and 16% of Nursing used extremity dosimeters as compared to chest dosimeters. The data from the measurements indicate that not all individual dosimeters are used properly. Generally, both in the measurements as in national registries, the hand doses were higher for professionals who prepared the radiopharmaceutical (NMT) than those who injected (Nursing). The value measured by chest dosimeters can be used to estimate the equivalent dose to the eye lenses, except for NMT at preparation practices at conventional NMS, where the equivalent dose of the lens is about 2 times higher than the dose at the chest. The most exposed areas of the hands are the tips of the index

    Natural radioactivity in soils, rocks and construction materials, due to {sup 40}K and the natural series of {sup 232}Th and {sup 2}'3{sup 8}U, is the main contribution to external exposure in mankind. In this work, activity concentrations of {sup 226}Ra ({sup 238}U series), {sup 232}Th and {sup 4}'0K were determined for 50 white latex wall paints samples, commercialized in Brazil, namely 15 Economic quality samples, 15 Standard quality samples and 20 Premium quality samples and for a single titanium dioxide sample. The samples were tightly sealed and stored for a minimum period of 30 days, to reach the radioactive secular equilibrium from {sup 238}U and {sup 232}Th series, then measured by high resolution gamma ray spectrometry. The activity concentration was determined using the weighted average concentrations of {sup 214}Pb and {sup 214}Bi for {sup 226}Ra and {sup 228}Ac, {sup 212}Pb and {sup 212}Bi for {sup 232}Th. The {sup 4}'0K activity concentration was determined by its single transition of 1460.8 keV. Self attenuation correction factors of the samples whose densities are higher than 1.0 g.cm{sup -3}, were determined and used to make the necessary corrections. The radiological indices radium equivalent activity (Ra{sub eq}), activity concentration index (I{sub γ}), internal exposure risk index (H{sub in}) and external exposure risk index (H{sub ex}) and also the absorbed dose rate (D) and annual effective dose (D{sub ef}) were calculated from the activity concentrations of {sup 226}Ra, {sup 232}Th and {sup 40}K. The activity concentration values for {sup 226}Ra ranged from under the minimum detectable activity to 38.7 Bq.kg{sup -1}, for {sup 232}Th from under the minimum detectable activity to 101.2 Bq.kg{sup -1} and for {sup 40}K from under the minimum detectable activity to 256 Bq.kg{sup -1}. Ra{sub eq} ranged from 1.41 Bq.kg{sup -1} to 203 Bq.kg{sup -1}, I{sub γ} ranged from 0.0047 to 0.720, H{sub in} from 0.0076 to 0.653 and H{sub ex

    In this study it was assessed the occupational exposure to {sup 222}Rn at IPEN, SP, Brazil, nuclear materials storage site through the committed effective dose received by workers exposed to this radionuclide. The radiation dose was calculated through the radon concentrations at nuclear materials storage site. Radon concentrations were determined by passive detection method with solid state nuclear detectors (SSNTD). The SSNTD used in this study was the polycarbonate Makrofol E; each detector is a small square plastic of 1 cm{sup 2}, placed into a diffusion chamber type KFK. It was monitored 14 points at nuclear materials storage site and one external point, over a period of 21 months, changing the detectors every three months, from December 2004 to September 2006. The {sup 222}Rn concentrations varied from 196 {+-} 9 and 2048 {+-} 81 Bq{center_dot}m{sup -3}. The committed effective dose due to radon inhalation at IPEN nuclear materials storage site was obtained from radon activity incorporated and dose conversion factor, according to International Commission on Radiological Protection procedures. The effective committed dose received by workers is below 20 mSv{center_dot}y{sup -1}. This value is suggested as an annual effective dose limit for occupational exposure by ICRP 60. (author)

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

    Various countries have studied the possibility of adding ethanol to gasoline or using pure fuel ethanol as an alternative to petroleum derivatives. Brazil occupies a leading position in this scenario because with its National Alcohol Program (Programa Nacional do Alcool - PROALCOOL), created in 1975, it became the pioneer in setting up a biofuels program. Since then it has accumulated experience and gained mastery of the technology to produce ethanol from sugarcane. Hence there is a strong expectation that the country can become the world's main ethanol exporter. This thesis examines the main environmental impacts associated with the ethanol productive chain, which are relevant conditioning factors for the expansion of this industry in Brazil. The study describes the evolution of PROALCOOL and the overview of current structure of the brazilian sugar-alcohol sector, identifies technologies and environmental management policies, and presents the perspective of expansion of ethanol production. Thus, the study undertakes an extensive review of the literature and examines to what extent the creation and implementation of public and private environmental management policies (legal restrictions and market instruments, respectively) interfere with the expansion of these productive activities.

    Concern about greenhouse gas emissions and global climate change has raised awareness that forest-management strategies have a large potential for storing and absorbing carbon from the atmosphere. Other measures under consideration include the use of renewable biomass as a substitute for fossil fuel use. This thesis shows the potential of charcoal from renewable Eucalyptus plantations for reducing CO{sub 2} emissions by replacing charcoal from the harvest of native forest in the iron and steel industry located at Carajas region, state of Para, Brazil. The results show that, if deforestation in the Carajas region were stopped and substituted by renewable forests for charcoal production, within a 21-year time horizon some 470.000 hectares of native Amazon forests could be preserved, avoiding the emission of some 2.67 x 10{sup 6} tC/yr to the atmosphere, which is 3.2% of the current carbon emissions from fossil fuel consumption in Brazil (82,4 x 10{sup 6} tC/yr) at a cost of 2,65-3,84 US$/tC.

    The Guarapiranga Reservoir, located in Sao Paulo metropolitan region, Brazil, is responsible for supplying about 20% of the entire population's water needs of this region or approximately 3.7 million people. However, this system has shown significant degradation in water quality, due to untreated domestic sewage and industrial effluents. In this study sediment samples were collected at five points along the reservoir and total concentration of some major (Fe, K and Na), trace (As, Ba, Br, Co, Cr, Cs, Hf, Hg, Rb, Sb, Sc, Ta, Tb, Th, U, V and Zn) and rare earth (Ce, Eu, La, Lu, Nd, Sm, Tb and Yb) elements were determined by instrumental neutron activation analysis (INAA). By inductively coupled plasma optical emission spectrometry (ICP OES) the concentrations of Al, Ba, Be, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb, Ti, V e Zn were determined after digestion procedure following US EPA 3051 methodology. The concentrations of metals Cd and Pb were determined by graphite furnace atomic absorption spectrometry (GFAAS) and total Hg by cold vapor atomic absorption spectrometry (CVAAS). Methodology validation according to precision and accuracy was performed by reference materials analyses for the three different analytical techniques used. Multielemental results obtained by INAA were compared to NASC (North American Shale Composite), Upper Continental Crust (UCC) and soil from Guarapiranga park values. The Enrichment Factor (EF) and Geo accumulation Index (Igeo) were also evaluated for these data.

    Tillandsia usneoides L. is an epiphytic bromeliad that lives on trees or other kinds of inert substrates, absorbing water and nutrients directly from the environment without roots. Due to its morphological and physiological characteristics, this species accumulates the pollutants present in the atmosphere. In the present work, Tillandsia usneoides was used as a bio monitor of metal atmospheric pollution in Sao Paulo, Brazil, which is the biggest city in South America with a population of 18 million inhabitants and a strong industrial activity. The urban area is polluted by industrial emissions but, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB), the governmental agency of air quality control, regularly occurring emissions from about 7.8 million motor vehicles provide the principal source of air pollution. The Tillandsia samples were collected from an unpolluted area and were exposed bimonthly in 10 sites of the city with different pollution levels and in a control site. After exposure, trace metals were analyzed in the plant by instrumental neutron activation analysis and ICP-MS (Pb, Cd, Co, Cu, Ni, Sb e V). The results of the investigation showed a notable concentration of Co and Ni in the plants exposed in an industrial area where there is a metal processing plant, which produces about 600 tons/year of Co and 16,000 tons/year of Ni. Copper and chromium were equally distributed in industrial regions and in sites near heavy traffic avenues, suggesting that these elements can be associated to both vehicular and industrial sources. A high accumulation of Cd in the plant exposed in industrial areas indicates industrial activities as the main source of this element.

MÉTODOS: Utilizou-se metodologia proposta pela Organização Mundial da Saúde (WHOQOL-BREF e WHOQOL-DIS para a construção dos instrumentos adaptados para população surda em Língua Brasileira de Sinais (Libras. A pesquisa para execução do instrumento consistiu de 13 etapas: 1 criação do sinal qualidade de vida; 2 desenvolvimento das escalas de respostas em Libras; 3 tradução por um grupo bilíngue; 4 versão reconciliadora; 5 primeira retrotradução; 6 produção da versão em Libras a ser disponibilizada aos grupos focais; 7 realização dos grupos focais; 8 revisão por um grupo monolíngue; 9 revisão pelo grupo bilíngue; 10 análise sintática/semântica e segunda retrotradução; 11 reavaliação da retrotradução pelo grupo bilíngue; 12 filmagem da versão para o software; 13 desenvolvimento do software WHOQOL-BREF e WHOQOL-DIS em Libras. RESULTADOS: Características peculiares da cultura da população surda apontaram a necessidade de adaptações na metodologia de aplicação de grupos focais quando compostos por pessoas surdas. As convenções ortográficas da escrita das línguas sinalizadas não estão consolidadas, o que trouxe dificuldades em registrar graficamente as etapas de tradução. As estruturas linguísticas que causaram maiores problemas de tradução foram as que incluíram expressões idiomáticas do português, muitas sem conceitos equivalentes entre o português e a Libras. Foi possível construir um software do WHOQOL-BREF e WHOQOL-DIS em Libras. CONCLUSÕES: O WHOQOL-BREF e o WHOQOL-DIS em Libras possibilitarão que os surdos se expressem autonomamente quanto a sua qualidade de vida, o que permitirá investigar com maior precisão essas questões.

    The cranio vertebral junction (CVJ) comprises the occiput, atlas, their joints and ligaments. Besides conventional x-rays other imaging methods are need for the assessment of CVJ including high resolution computerized tomography (CT) and magnetic resonance imaging (MRI) which provide specific parameters such as field of view, slice thickness and incremental movement of the patient. A dynamic study is also important to assess the stability of the cranio vertebral junction and the effect upon the bulbomedullary junction. The aim of this study is to review the techniques used in the evaluation of the CVJ, the semiological parameters, and the most frequent disorders affecting this region. We review the literature and present conventional x-ray, CT and MRI images from the didactic file of the Radiology service 'Med Imagem - Beneficiencia Portuguesa de Sao Paulo, SP, Brazil, of cases with normal anatomy and the main congenital and acquired disorders of the CVJ. In daily practice, CVJ disorders are diagnoses using CT and MRI scans of the head and cervical spine. It is essential to be familiar with these conditions in order to preform specific tests which will allow a detailed study of the CVJ, thus providing the basis for the treatment, whenever indicated.

    The intraoral radiography is widely performed in the dental office due to low cost and agility. The doses in intraoral radiology are considered low, however it is known that doses below the threshold for deterministic radiation has the potential to induce stochastic effects. An intraoral radiography has a risk of inducing fatal cancer or serious in order of 1:10,000,000. Besides the patient, the dentist may also be being exposed to radiation during the work with the radiographics practices. The bibliographies demonstrates the lack of information on radiation protection of dentists, however, the occupational dose reduction was observed in radiology over the past 14 years. This work aims to evaluate the effective dose of radiation to which workers can be exposed dentists in dental offices to perform intraoral radiographs. In this context, a study was be conducted between June 2013 and May 2014 with 44 professionals in Curitiba city. For each dentist was given a personal dosimeter to be used for 30 days. During this period, the number of radiographies and the length of the cable triggers of the X-ray equipment was registered and, the dosimeter´s dose was read. It was observed that the cables triggers meet regulatory standards and allow dentists to get the mean minimum distance of two meters from the radiation source in 93% of cases. Through analysis of the doses, it was concluded that occupational exposures of these workers are within the recommended threshold by regulatory 453/1998 of the Ministry of Health from Brazil.

    This study evaluates the daily dietetic ingestion of Hg and some nutrients of pre-scholar children from eight communities of Amazonas state, Brazil. Some children from each community were selected and their diets (24 hours total consumption) were collected by the duplicate quantity method and a pool of diets composed for each of these communities. The diet samples were analysed for the Hg total content by a CV AAS linear accelerator and neutron activation analysis for determination of Ca, Fe, K, Se and Zn micro nutrients. Both analytical methodologies precision and accuracy were validated using the certified reference materials analysis. The provisional tolerable weekly ingestion (PTWI) for Hg and the daily micro nutrient ingestion were calculated for each group, considering an 10 kg average weight for each child. The obtained results for all diets were shown the inadequacy prevail for the evaluated micro nutrients, and some communities exceeded the limit of 5 {mu}g Hg/kg of body weight (PTWI). Those results suggested that the nutritional education program must be implemented at those communities, aiming the better utilization of the local food natural resources. (author)

    The purpose of this work is to assess the contribution of the liquid effluents of the Duque de Caxias Refinery (REDUC) in the water and sediment contamination in the estuarine Iguacu-Sarapui system, a tributary of the Guanabara Bay, Rio de Janeiro, Brazil. Since 2002 is being conducted a quarterly monitoring of some parameters in water, river sediments and treated liquid effluent, such as: pH, suspended solids, total sedimented solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total organic carbon, oil and grease (O and G), phenols, sulfide, ammonia, metals and metalloids (V, Cr, Pb, Ni, Cu, Cd, Zn, Hg, As, Se , Co, Fe, Mn), polycyclic aromatic hydrocarbons, coprostanol and cholesterol (indicators of domestic wastes). The obtained results show that the effluents meet the legal standards and the treated liquid effluents from REDUC in the estuarine system have little or no impact on river water quality. The higher levels of contaminants detected in water and sediments samples are directly related to untreated domestic sewage from urban areas. (author)

    The aim of this work was to evaluate the influence of percent labeling of the radiopharmaceutical {sup 99m}Tc-MIBI on the procedures adopted by the nuclear medicine clinics in Recife, Pernambuco State, Brazil, and their possible interference with image quality in myocardial perfusion examinations. This work was performed at two nuclear medicine services in Recife that use pharmaceuticals provided by two different manufacturers: Cardiolite, provided by Dupont and Cardiosyd, provided by SYDMA. The pH, percent labeling and stability of samples of {sup 99m}Tc-MIBI and the percent uptake in heart and liver of a number of patients were evaluated. The results showed that the pH values measured in all samples of both radiopharmaceuticals were within the limits recommended. In 48% of the Cardiolite samples, the percent labeling was less than 90%, which is the minimum recommended limit. On the other hand, 87,5% of the Cardiosyd samples measured values above 98%. Both radiopharmaceuticals had good labeling stability, even in samples with low percent labeling efficiencies. In spite of the higher percent labeling of Cardiosyd its heart uptake is similar to that observed with the Cardiolite, even when the percent labeling is lower than 90%. On the other hand, the image quality, according to physicians, evaluation was poorer for Cardiosyd images, due to high noise and poor sharpness. (author)

    The municipality of Monte Alegre, located in the Amazonian State of Para, Brazil, presents scattered areas with increased levels of natural radiation due to uranium rocks. The objectives of this dissertation were: to evaluate the mortality trend among Monte Alegre residents, and to compare it with that observed in neighbor municipalities (Alenquer and Prainha) without natural radiation sources; and to determine the impact of cancer distribution either in Monte Alegre or control counties population, taking into account their estimates of cancer incidence and mortality. The dissertation was organized in two papers. The first one aimed to evaluate the mortality trend for all causes of death, cancer, and unknown causes of death occurred between 1981-2005. Analyzed data was provided by the Brazilian National Mortality Information System (SIM), being the general population of the State of Para used as reference. In the second paper, cancer mortality risks at selected sites were ascertained using standardized mortality ratios (SMR) and mortality odds ratios (MOR). Additionally, cancer mortality risk ratios of Monte Alegre and control counties were obtained towards the ratio between SMRs of selected cancer sites in both areas. Three different sources of data were used to retrieve all cancer cases in the studied area, and therefore, to estimate cancer incidence in the studied populations: the diagnosed cancer cases at the regional reference centers for oncological care settled in Santarem, Belem and Manaus; the cancer-related hospitalization authorization records obtained at the Brazilian National Health System (SUS) registries; and primary data of cancer reported by local residents at a population-based health survey conducted by our research team in 2007-2008. A declining trend for all causes of death mortality in Monte Alegre general population, as well as for the unknown causes of death, was observed along the studied time series for both gender.

    One way of improving well production is the addition of demulsifier already in the gas lift. This is due to the apparent viscosity of water-in-oil emulsions being higher than apparent viscosity of crude oil, which in turn is higher than the apparent viscosity of an water-in-oil dual phase admixture and is also higher than the apparent viscosity of an oil-in-water emulsion. However, there are some situations where, in order to obtain separate flows of oil and water phases, demulsifier should be added in specific amounts in order to promote the desired phase separation. In heavy oils water and oil phase separation may be hard to obtain, however, the right demulsifier amount may imply in a considerable decrease in petroleum viscosity even without the appearance of two phases, making the flow easier. This work has evaluated the viscosity of a heavy crude having API degree 14 and BSW 52%, as a function of the addition of different amounts of DEMTROL BR 67, manufactured by Dow Quimica/Comab, Brazil, as demulsifier.

    This study aims to assess the progression of kerma rate levels in the air due to the increase of collection, storing and storage of radioactive waste in the new building (after expansion) of the radioactive waste disposal (RWD) of the Instituto de Engenharia Nuclear (IEN/CNEN-RJ), Brazil. This review is carried out every six months at IEN with thermoluminescent dosimeter lithium fluoride LiF: Mg, Cu, P (TLD-100H). Here are the average values of kerma rate for the period 2008- 2012. In this context, the methodology used for selection and choices of detectors used in dosimeters is presented. The detectors were chosen through homogeneity criteria of the pack, standardization factor and coefficient of variation (CV%). The monitoring points and the exposure time of the detectors are chosen considering various factors, including the rate of occupation and indoor and outdoor positions to RWD. These evaluations showed that the contribution of the new waste disposal in increasing kerma rate of IEN, has proved to be insignificant, that is, the presence of RWD does not contribute to increased environmental kerma rate in the region around this installation.

  1. Evaluation of the ocular protection for low intensity therapeutic lasers; Avaliacao da protecao ocular para lasers terapeuticos em baixa intensidade

    The low intensity laser therapy (LILT) has been extensively used in medicine and dentistry presenting positive effects. However, the laser radiation can also cause adverse effects. Due to the ocular focalization property, in the wavelength from 400 to 1400 nm, the retina is more susceptible to damage by radiation than any other part of the human body. Then, the ocular protection is frequently emphasized. This protection must attenuate the radiation to a safe level. The International Electrotechnical Commission (IEC) standard IEC 60825-1 suggests safety requirements for medical laser equipment, including the ocular protection, based on maximum permissible exposure levels. The Brazilian legislation adopts a corresponding IEC standard, the NBR IEC 601.2.22, for safety requirements. The aim of this study was to analyze the adequacy of the ocular protectors furnished by four laser equipment manufacturers, commercially available in Brazil, commonly used for LILT. For this purpose, the laser equipment and the respective ocular protectors were characterized. The adequacy was verified according to the IEC standards. It was found, among other results, ocular protectors attenuating to safe levels the radiation emitted by the respective laser equipment, however, presenting inadequate visual transmission. Inefficient protection and protection indicated in cases where they were not necessary were also observed. (author)

    Nuclear equipment meters are mainly used in the industry in quality control and process control. The principle of operation consists in a shielded radioactive source together with a radiation detector such that the radiation interacts with the material to be analyzed before reaching the detector, providing real time data. Can be as their fixed and mobile mobility, the unique properties of ionizing radiation are used in three basic modes, transmission, backscatter or dispersion or induced (reactive). With the advancement and technological modernization in the world, the demand for nuclear gauges becomes increasingly larger. Currently in Brazil there are about 465 process control plants and 21 portable systems and Mozambique about 45 facilities using nuclear gauges. This font registration is done through a process called source inventory that allows also to know the category of the source, the danger or risk to human health that the source offers. The handling of this equipment requires personnel, certified, skilled and well trained in radiation protection area in accordance with the requirements of the various CNEN Rules. Due to the presence of radioactive source and because these devices are used by workers risk because there external radiation. In this context, we made the smear test in two fixed meters from the IRD industry laboratory, which determines the integrity of the source package, mandatory item in periodic integrity testing of the radiation source of this type of device. A set of procedures is made for its implementation as an evaluation of the radiological risk by radiological survey. It was intended to contribute to the learning handling and safe use of these meters. (author)

    Kaolinitic clays are vastly used in ceramic industry. Kaolinitic clay that are not coloured after firing are very useful in the production of ceramics because of their aesthetic aspect after firing. In this work clay material from Vitoria da Conquista (South- West Bahia, Brazil) was characterized by several techniques. The differential Scanning Calorimetry (DSC) shows a kaolinite characteristic curve with an endothermic peak at 492 deg C, which corresponds to the kaolinite - metakaolinite transformation. The transformation of alpha to beta quartz characterized by a 573 deg C peak was also observed in DSC. The samples were also characterized by water absorption and x rays powder diffraction. The 1100 deg C burned samples were tested by flexural strength. (author)

    Mammography is the image exam called 'gold standard' for early detection of breast cancer. 111 Brazil, more than eight million mammograms are carried out per year. With the advancement of technology, the digital systems CR and DR for this diagnostic modality have been increasingly implemented, replacing the conventional screen-film system, which brought environmental problems, like the disposal of chemical waste, and is also responsible for the rejection of radiographic films with processing artifacts. Digital systems, besides not experiencing the problem of environmental pollution, are still capable of image processing, allowing a much lower rejection rate when compared to the conventional system. Moreover, the determination of an accurate diagnosis is highly dependent on the image quality of the examination. To ensure the reliability of the images produced by these systems, it is necessary to evaluate them on a regular basis. Unfortunately, there is no regulation in Brazil about the Quality Assurance of these systems. The aim of this study was to develop a set of test objects that allow the evaluation of some parameters of image quality of these systems, such as field image uniformity, the linearity between the air Kerma incident on detector and the mean pixel value (MPV) of the image, the spatial resolution of the system through the modulation transfer function (MTF) and also to suggest an object to be applied in the evaluation of contrast-to-noise ratio (CNR) and signal-difference-to-noise ratio (SDNR). In order to test the objects. 10 mammography centers were evaluated, seven with CR systems and three with the DR systems. To evaluate the linearity, besides the test objects high sensitivity dosimeters were necessary to be used, namely LiF:Mg,Cu,P TL dosimeters. The use of these dosimeters was recommended in order to minimize the time required to perform the tests and to decrease the number of exposures needed. For evaluation of digital images in DICOM

    Breast cancer is the leading cause of cancer deaths in women. Currently, the most effective method for early detection of this cancer is the mammography, and to achieve the standard definition and contrast, the whole system of imaging must operate under optimal conditions. This paper presents the results of the assessment of mammography centers in the state of Minas Gerais, which was held with the aim of supporting the actions of the State Program of Quality Control in Mammography. These results indicated that less than half of mammography achieved the minimum standard of image quality, endorsing the need of a monitoring more efficient and effective, which led to the establishment, in Minas Gerais, of the monthly monitoring of image quality in mammography.

    In nuclear medicine, radioisotopes are bound to various pharmaceuticals for use in diagnostic and therapeutic applications. These unsealed sources are administered in various forms to patients, who remain radioactive for hours or days, and represent a source of potential radiation exposure for others. Thus, in nuclear medicine departments, radiation protection of workers and members of the public (especially persons accompanying patients) must consider this exposure. In this study, thermoluminescent dosimeters were given to various persons who were accompanying patients in two nuclear medicine departments in Recife, Pernambuco State, Brazil. Exposure results are given, and issues regarding exposure conditions and times for members of the public in these departments are discussed. (author)

    In Brazil the most important concentrations of monazite sands occur in the beaches and sandbanks that extend throughout the coast, from the State of Rio Grande do Norte down to the State of Rio Grande do Sul, Brazil. Nowadays, the most important Brazilian monazite concentrations - considered as being the fourth worldwide reservoir of rare-earth elements - are located at the north seacoast of the State of Rio de Janeiro, near Buena town. At this location the Brazilian Nuclear Industries - INB - manages an industrial complex for prospecting, mining and physical separation and concentration of monazite sands. Among the elements present at the monazite sands there are the radioelements thorium and uranium, which make the monazite sand a radioactive mineral. Monazite is constituted basically of 62% in TR{sub 2}0{sub 3} (rare-earth oxides), 5,5% of thorium in Th0{sub 2} (thorium oxide) and 0,25% of uranium in U{sub 3}0{sub 8} (uranium oxide). The general objective of the present work was to estimate the occupational doses at the industrial complex for prospecting, mining and physical separation and concentration of monazite sands located at Buena, at the north of the State of Rio de Janeiro. The occupational exposures occur mainly through the inhalation of airbone dust particles of mineraIs containing thorium and uranium, during the prospection and physical separation and concentration of monazite. To evaluate the impact of the occupational exposures during the physical separation and concentration of monazite, it was necessary to evaluate the effective equivalent doses due to thorium contamination of the air and the exposures due to the daughter radionuclides from the natural series of uranium and thorium. The results obtained at the present work showed that, although occupational doses are within the annual dose limits established by the Brazilian regulatory authority - CNEN - in some of the working places within the industrial complex the concentrations of

    The search for sustainable and more rational means of power generation motivates the scientific crew to search for more efficient and cleaner systems. Oil dependence becomes from the kind of development that the humanity had and cannot be dismissed. The question is how to use this source in a more intelligent way. Fuel Cells are electrochemical devices that convert into electric energy the chemical energy from oxi-reduction reactions between a fuel and an oxidant. The current fuel used in a Fuel Cell is hydrogen and oxygen is the oxidant. The great advantage of this device is its efficiency, higher than the one achieved with internal combustion engines. Also Fuel Cells are not limited by Carnot's efficiency. This paper is about the implementation of a distributed generation system using Fuel Cells. Technical aspects are approached together with economical and environmental needs. The already existence of Gas pipelines and the grown production of Natural Gas presented by Brazil turns it into a good market for the implementation of this energy source. The evaluation of this paper shows that is technically possible to use NG in Fuel Cells, mostly in South and Southeast regions, applying the distributed generation of energy concept. The most interesting in a strategic manner is that Brazil already have an indication that it's capable of developing this technology, opening a new market tuning with world's new technological developments. Many research centers develop this technology, not only from the cell composition itself, but also manufacturing techniques. (author)

The patients were divided in seven groups, according to the presence of these symptoms and signs. All examinations were made in a private clinic in the city of Rio de Janeiro, Brazil. Correlating these patients with the results of the magnetic resonance images, we found 57 micro adenomas, 31 normal examinations, 22 macro adenomas, 11 pituitary hyperplasias, 7 empty sella and 7 cases included in other aspects. The micro adenoma predominated in groups 1 (GAH), 2 (GH), 3 (HA) and 5 (H), that is, in all groups whose patients had hyperprolactinemia. In macro adenomas, a bright signal on T 1-weighted images indicates pituitary apoplexy with intratumoral hemorrhage. All in all, the magnetic resonance imaging is excellent method to be used in the evaluation of patients with changes in the hypothalamic-pituitary axis. (author)

    This paper is a comparative ethnography of the therapeutic practices at two different spa locations: Caldas da Imperatriz, SC, Brazil, and Termas da Sulfurea in Cabeco de Vide, Portugal. The comparison reveals the existence of contrasting 'explanatory models' held by the spa-goers as well as by the official medical systems. In the Portuguese context this model is highly medicalized; in the Brazilian case, spa treatments are viewed as 'alternative' or 'complementary' therapy and are also related to religious philosophies. Each model corresponds to a different idiom expressing certain experiences and world views, one focusing on 'pains' (dores) and the other on 'energy' (energia), the former leading to the rationale of 'curing', the latter to the notion of 'energizing'. In this paper the author intends to analyze and contrast the categories found in these models, which originate from different conceptions of health, illness and healing for Brazilian and Portuguese spa-goers.

    In Brazil, the multi mixture have being used since the eighties as an alternative against severe infantile malnutrition of the poorest population. However, its use is still reason of controversies mainly due to: the presence of anti nutritional factors, the microbiological quality and the nutritional value. Considering the routine use of multi mixture in the region, this work aimed to evaluate samples of multi mixture were collected in the metropolitan area of the City of Belo Horizonte/MG for determining the anti nutritional factors (phytic and oxalic acids), the microbiological quality, the centesimal and mineral composition, and still the induced effect in these factors of the gamma radiation. For the analyses, the samples passed by the process of gamma irradiation at doses of: 2, 4, 6, 8 and 10 kGy and then were evaluated anti nutritional factors (phytic acid and oxalic), the microbiological quality (yeasts and molds, Salmonella, Coagulase positive Staphylococcus, Bacillus cereus, coliform to 45 deg C) to full percentage (moisture, ash, proteins, carbohydrates and lipids) and the efficiency of the method of Paramagnetic Electronic Resonance (EPR) in the detection of irradiated samples. The mineral composition of the samples was carried out by the irradiation by Neutronic Activation. The methods used were searched in literature. The obtained results suggest that the concentration of the phytic and oxalic acids can not be appropriated for the children with severe nutritional deficit and that it would be necessary additional control in their daily ingestion due to the absorption of essential minerals. In general the samples had presented acceptable microbiological quality for consumption, except by one of it. The data of the centesimal and mineral composition, in the usually recommended portions, showed lower concentration than recommended for children. Any significant alteration in phytic and oxalic acids as well as in the centesimal composition were detected

    Intensity modulated radiation therapy (IMRT) is currently being implemented in a rapidly growing number of centers in Brazil. As consequence many institutions are now facing the problem of performing a comprehensive quality control program before and during the implementation of IMRT in the clinical practice. This paper proposes a methodology for quality control and presents the results and evaluations of the data obtained from the proposed methodology. Ionization chamber and two-dimensional array detector were performed in IMRT treatment planning in order to assess the absolute value of the total dose of all fields. The relative total dose distribution of all fields was measured with a radiochromic film and a two-dimensional array in a phantom. A comparison between measured and calculated dose distributions was performed using the gamma-index method, assessing the percentage of points that meet the criteria of ±3% dose difference and ±3mm distance to agreement. As a result and review of 113 tested IMRT beams using ionization chamber and 81 using two-dimensional array, the proposal was to take an action level of about ±5% compared to the treatment planning systems and measurements, for the verification of the dose in a single point at the low gradient dose region. Analysis of the two-dimensional array measurements showed that the gamma value was <1 for 97.7% of the data and for the film the gamma value was <1 for 96.6% of the data. This work can establish action levels required for quality control program proposed and implemented in the Department of Radiotherapy - Hospital das Clinicas in Sao Paulo that allows an accurate delivery of dose in 'sliding-window' IMRT with micro multi leaf collimator.

    This study aims to evaluate the repeatability of symmetry and flatness of the photon beam of 6 MV linear accelerator Oncor Impression, Siemens, from the Radiotherapy Department of the Hospital das Clinicas da Faculdade de Medicina de Ribeirao Preto - USP. In total they were collected 102 measures, weekly, through two-dimensional detector of ionization chambers, Matrixx Evolution, IBA Dosimetry, connected to a computer with software OmniProI'mrt. The isocenter of the linear accelerator was placed in the center of the sensitive volume of the detector with solid water plates above and below these. Data were collected with 100 UM, with field size 10 x 10 cm². The flatness and symmetry values were calculated by the software used. The first measurement of this work was used as reference, the others were compared with it, taking into account the values of permissible variation for these parameters. The minimum, maximum and average value were analyzed. The literature indicates that the flatness and symmetry values should not vary by more than 2 and 3%, respectively. The results of this work show that the values of these parameters for the linear accelerator study are within the permissible variations in protocols and are therefore able to appropriate clinical use.

    Many developed countries have established a goal of self-sufficiency in food production, while many other obtain their principal foreign exchange through food exports. For these reasons, it is essential to eliminate losses in food products. It is no less important to prevent or combat food-transmitted diseases, principally across poultry and poultry derivatives, which play a major role in certain infections and is the focus of national public health goals in order to increase the international commerce. In tropical countries, perishable products represent the largest markets. The population lives in a constant battle against the deterioration of these foods. Such loss is enormous where the climate favors the proliferation of agents of decomposition and acceleration of putrification. Increasing the useful life of these perishable products will provide producers the option of commercializing them in low harvest season, thus achieving higher prices, and providing sensible growth to the agro-industrial market. Treatment of perishables with gamma radiation presently constitutes one of the most modern, safe, and efficient methods for increasing food preservation. The irradiation of foods can offer various special advantages such as: kill or sterilize pathogenic organisms in food, improving their quality and duration, reducing the level of toxics, slow or stop the aging of roots and tubers, disinfect products of animal and vegetable origin thus slowing their decomposition, increasing their shelf-life, and prolonging their conservation refrigeration. The practice of irradiating foods for the treatment of microorganisms has begun to gain momentum in Brazil, where roughly 25% of all food produced annually is lost to disease and insects activity, increased by lack of adequate storage treatments. Various countries have already adopted the method that, when practiced properly by qualified professionals, does not cause side effects other than the extension of useful life. In

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

    The volcanic rocks of the Mata da Corda Formation (Upper Cretaceous) in Minas Gerais, Brazil, are mafic potassic to ultra potassic rocks of kamafugitic affinity containing essentially clinopyroxenes, perovskite, magnetite and occasionally olivine, phlogopite, melilite pseudomorphs and apatite. The felsic phases are kalsilite and/or leucite pseudomorphs. The rocks are classified as mafitites, leucitites and kalsilitites. The analysis of the available data of the rocks studied, based on the relevant aspects of the main proposals for the classification of alkaline mafic to ultramafic potassic rocks leads to the conclusion that Sahama's (1974) proposal to divide potassium rich alkaline rocks in two large families is the one to which the Mata da Corda rocks adapt best. According to this and the data in the literature on the mineralogy and mineral and rock chemistries of the other similar occurrences, these rocks may be interpreted as alkaline potassic to ultra potassic rocks of hamafugitic affinity. 11 figs., 5 tabs

    Full Text Available A história da maconha no Brasil tem seu início com a própria descoberta do país. A maconha é uma planta exótica, ou seja, não é natural do Brasil. Foi trazida para cá pelos escravos negros, daí a sua denominação de fumo-de-Angola. O seu uso disseminou-se rapidamente entre os negros escravos e nossos índios, que passaram a cultivá-la. Séculos mais tarde, com a popularização da planta entre intelectuais franceses e médicos ingleses do exército imperial na Índia, ela passou a ser considerada em nosso meio um excelente medicamento indicado para muitos males. A demonização da maconha no Brasil iniciou-se na década de 1920 e, na II Conferência Internacional do Ópio, em 1924, em Genebra, o delegado brasileiro Dr. Pernambuco afirmou para as delegações de 45 outros países: "a maconha é mais perigosa que o ópio". Apesar das tentativas anteriores, no século XIX e princípios do século XX, a perseguição policial aos usuários de maconha somente se fez constante e enérgica a partir da década de 1930, possivelmente como resultante da decisão da II Conferência Internacional do Ópio. O primeiro levantamento domiciliar brasileiro sobre consumo de psicotrópicos, realizado em 2001, mostrou que 6,7% da população consultada já havia experimentado maconha pelo menos uma vez na vida (lifetime use, o que significa dizer que alguns milhões de brasileiros poderiam ser acusados e condenados à prisão por tal ofensa à presente lei.

    The textile industry is among the main activities Brazil, being relevant in number of jobs, quantity and diversity of products and mainly by the volume of water used in industrial processes and effluent generation. These effluents are complex mixtures which are characterized by the presence of dyes, surfactants, metal sequestering agents, salts and other potentially toxic chemicals for the aquatic biota. Considering the lack of adequate waste management to these treatments, new technologies are essential in highlighting the advanced oxidation processes such as ionizing radiation electron beam. This study includes the preparation of a standard textile effluent chemical laboratory and its treatment by electron beam from electron accelerator in order to reduce the toxicity and intense staining resulting from Cl. Blue 222 dye. The treatment caused a reduction in toxicity to exposed organisms with 34.55% efficiency for the Daphnia similis micro crustacean and 47.83% for Brachionus plicatilis rotifer at a dose of 2.5 kGy. The Vibrio fischeri bacteria obtained better results after treatment with a dose of 5 kGy showing 57.29% efficiency. Color reduction was greater than 90% at a dose of 2.5 kGy. This experiment has also carried out some preliminary tests on the sensitivity of the D. similis and V. fischeri organisms to exposure of some of the products used in this bleaching and dyeing and two water reuse simulations in new textile processing after the treating the effluent with electron beam.

    In this work the radiological protection conditions and dose at the entrance of pediatric patients undergoing dental intraoral radiographs were evaluated. The study was conducted in two clinics of the dentistry course at the Federal University of Pernambuco, Recife, PB, Brazil, equipped with conventional X-ray apparatus, with 60 and 70 kV. 254 exams of 113 patients between the ages of 3 to 12 years were evaluated. The skin entrance dose was estimated using TLD-100 thermoluminescent dosemeters. During the examination were also recorded information regarding the time of exposure, radiographic technique used, use of thyroid protectors and lead apron, angle and distance of the cone Locator to the patient's skin. The results showed that the input skin doses ranged from 0.3 mGy to 10mGy. The lead apron was used in 71% of exams while the thyroid shield was only used in 58% of the exams. The exposure times ranged from 0,5s to 1,5s. From the results it can be concluded that the radiological procedures are not optimized and that in some cases the patient dose is high.

    Full Text Available Brazil faces a challenge to develop biomonitoring tools to be used in water quality assessment programs, but few multimetric indices were developed so far. This study is part of an effort to test and implement programs using benthic macroinvertebrates as bioindicators in Rio de Janeiro State. Our aim was first to test the Multimetric Index for Serra dos Órgãos (SOMI for a different area - Serra da Bocaina (SB - in the same ecoregion. We sampled 27 streams of different sizes and altitudes in the SB region. Despite the environmental similarities, results indicated biological differences between reference sites of the two regions. Considering these differences, we decided to develop an index specific for the SB region, the Serra da Bocaina Multimetric Index (MISB. We tested twenty-two metrics for sensitivity to impairment and redundancy, and six metrics were considered valid to integrate the MISB: Family Richness, Trichoptera Richness, % Coleoptera, % Diptera, IBE-IOC index, EPT / Chironomidae ratio. A test of the MISB in eleven sites indicated it was more related to land-use and water physico-chemical parameters than with altitude or stream width, being a useful tool for the monitoring and assessment of streams in the bioregion.

    Soil contamination is today one of the most important environmental issues for society. In the past, soil pollution was not considered as important as air and water contamination, because this was more difficult to be controlled, becoming an important topic in studies of environmental protection worldwide. Based on this, this paper provides information on the determination of metals in soil samples collected in Zona da Mata, Pernambuco, Brazil, where normally the application of pesticides, insecticides and other agricultural additives are used in a disorderly manner and without control. A total of 24 sampling points were monitored. The analysis of Mn, Fe, Ni, Zn, Br, Rb, Sr, Pb, Ti, La, Al, Si and P were performed using Energy Dispersive X-Ray Fluorescence. In order to assess the development of analytical method, inorganic Certified Reference Materials (IAEA-SOIL-7 and SRM 2709) were analyzed. In each sampling site, the geoaccumulation index were calculated to estimate the level of metal contamination in the soil, this was made taking into account the resolution 460 of the National Environmental Council (CONAMA in Portuguese). The elemental distribution patterns obtained for each metal were associated with different pollution sources. This assessment provides an initial description of pollution levels presented by metals in soils from several areas of Zona da Mata, providing quantitative evidence and demonstrating the need to improve the regulation of agricultural and industrial activities.

    Soil contamination is today one of the most important environmental issues for society. In the past, soil pollution was not considered as important as air and water contamination, because this was more difficult to be controlled, becoming an important topic in studies of environmental protection worldwide. Based on this, this paper provides information on the determination of metals in soil samples collected in Zona da Mata, Pernambuco, Brazil, where normally the application of pesticides, insecticides and other agricultural additives are used in a disorderly manner and without control. A total of 24 sampling points were monitored. The analysis of Mn, Fe, Ni, Zn, Br, Rb, Sr, Pb, Ti, La, Al, Si and P were performed using Energy Dispersive X-Ray Fluorescence. In order to assess the development of analytical method, inorganic Certified Reference Materials (IAEA-SOIL-7 and SRM 2709) were analyzed. In each sampling site, the geoaccumulation index were calculated to estimate the level of metal contamination in the soil, this was made taking into account the resolution 460 of the National Environmental Council (CONAMA in Portuguese). The elemental distribution patterns obtained for each metal were associated with different pollution sources. This assessment provides an initial description of pollution levels presented by metals in soils from several areas of Zona da Mata, providing quantitative evidence and demonstrating the need to improve the regulation of agricultural and industrial activities.

    The consumption of collard greens (Brassica oleracea cv. acephala) and broccoli (Brassica oleracea L. var. italica) has been inversely associated with morbidity and mortality caused by degenerative diseases. These species are highly consumed in Brazil, which enables its use as minimally processed (MP). The growing worldwide concern with the storage, nutritional quality and microbiological safety of food has led to many studies aimed at microbiological analysis, vitamin and shelf life. To improve the quality of these products, radiation processing can be effective in maintaining the quality of the product, rather compromising their nutritional values and sensory. The aim of this study was to evaluate the effectiveness of gamma radiation from {sup 60}Co at doses of 0, 1.0 and 1.5 kGy on the reduction of microbiota in these plants, and analyze their nutritional and sensory characteristics. The methodology used in this study was microbiological analysis, colorimetric analysis, analysis of phenolic compounds, antioxidant analysis and sensory analysis. The microbiological analysis showed a decrease in the development of populations of aerobic microorganisms, psychotropic and yeast and mold with increasing doses of radiation. The sensory analysis showed no significant difference between different times of cooking analyzed. The analysis of phenolic compounds, significant differences between the samples, suggesting that with increasing dose of irradiation was an increase in the amount of phenolic compounds found in broccoli and collard greens MP. It can be observed that the sample of control collard greens showed high antioxidant activity and for the samples treated by irradiation was a decrease of percentage. In contrast the samples of broccoli show an increase in the rate of scavenging DPPH with increase of the dose of radiation. The colorimetric analysis revealed that for samples of MP collard greens and broccoli foil of no significant differences, but for samples of

    In recent decades, there has been a great advancement in research in developing drugs from plants. Nevertheless, little significant care exists in the literature about the stable concentration of elements, as well as the activity concentration of '2{sup 38}U and {sup 232}Th decay products in plants used for this purpose in Brazil. The presence of stable elements and radionuclides in plants constitutes the pathway for their migration to humans, via uptake of tea or remedies made with medicinal herbs. Peperomia pellucida, whose popular name is 'erva de jabuti', is a plant known by its medicinal usages, such as healing and analgesic properties plus antibacterial and antifungal activities against food fungi. In this study, the elemental composition of Peperomia pellucida and surrounding soil samples collected in the Botanical Garden in Rio de Janeiro was determined; the elemental concentration in the alcoholic extract and infusion processes of dry plants was also determined. The elemental concentration of As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn was determined in the leaves, aerial parts, including leaves, stems and roots of Peperomia pellucida, in their extracts obtained by maceration and infusions and in the surrounding soil by the Instrumental Neutron Activation Analysis (INAA). The analytical methodology used to determine the elements Cd, Hg and Pb was the Atomic Absorption Spectrometry (AAS); the activities of {sup 226}Ra, {sup 228}Ra and {sup 210}Pb were carried out by gross alpha and beta counting, after radiochemical separation. The quality of the obtained results was assured by the analyses of the certified reference materials IAEA-336 Lichen, IAEA-Soil-7, IAEA-326 Radionuclides in soil, NIST 1515 Apple Leaves and NIST 1542 Peach Leaves. The relative standard deviations and the relative errors obtained in these analyses indicated good precision and accuracy of the results. The essential

    Full Text Available OBJETIVO: Investigar a origem das preparações de heparina, na forma farmacêutica injetável, disponíveis no mercado brasileiro, discutindo o impacto do perfil dos produtos comercializados e das alterações na monografia da heparina na segurança do fármaco. MÉTODOS: Pesquisou-se o banco de dados de Produtos Registrados das Empresas de Medicamentos da Anvisa e o Dicionário de Especialidades Farmacêuticas (DEF 2008/2009. Foi realizado inquérito com as indústrias com autorização ativa para o comércio do fármaco no Brasil. RESULTADOS: Cinco indústrias possuem autorização para o comércio de heparina não fracionada no Brasil. Três são de origem suína e duas de origem bovina, sendo que apenas uma possui essa informação explicitada na bula. A efetividade e a segurança da heparina, estudadas em populações estrangeiras, podem não representar a nossa realidade, já que a maioria dos países não produz a heparina bovina. A heparina atualmente comercializada tem, ainda, aproximadamente 10% menos atividade anticoagulante que a anteriormente produzida, e essa alteração pode ter implicações clínicas. CONCLUSÃO: Evidências acerca da ausência de intercambialidade de doses entre as heparinas de origem bovina e suína e o diferenciado perfil de segurança entre esses fármacos indicam necessidade de acompanhamento do tratamento e da resposta dos pacientes. Eventos que ameacem a segurança do paciente devem ser comunicados ao sistema da farmacovigilância do país.OBJECTIVE: To investigate the biological origin of injectable unfractioned heparin available in Brazilian market by discussing the impact of the profile of commercial products and the changes in heparin monograph on the drug safety.

    Full Text Available Considering the different paths of knowledge production that Social psychologists have run in Brazil, the text makes a distinction between a stricto sensu Social Psychology and the lato sensu one. The stricto sensu Social Psychologycomprises the trends found in the historical development of the discipline and in scientific modernity: the mainstream "psychological" Social Psychology; the European "sociological" Social Psychology; the "micro-sociological" perspectives, since Mead. The lato sensu Social Psychology comprises the trends that emerged aside the subject's history or very recently, following other epistemological guidelines: the Marxist Social Psychology, institutional analysis, socio-historical Psychology, socio-constructionism, and the philosophical Social Psychology. The eight trends listed are then submitted to evaluations regarding the two basic dimensions of Social Psychology: societal and psychological. A comparative picture of those evaluations discloses differences between the stricto and lato sensu sets of Social Psychology, as well as between the several trends in the scope of each set.Considerando os variados rumos de produção de conhecimento trilhados no Brasil pelos psicólogos sociais, o texto faz distinção entre uma Psicologia Social stricto sensu e outra lato sensu.

    A water balance experiment was carried out in a red-yellow podzolic soil of the Northern Zona da Mata region, in the State of Pernambuco, Brazil. Six 11 m x 3m plots were planted with the IPA-206 variety of caupi beans (Vigna unguiculata (L.) Walp), which was genetically modified at the IPA Research Center in order to improve its resistance to water stress. The experiments were performed in two different periods of the year, so that the influence of the amount of rainfall on the crop yield could be evaluated. Stored water and water potential gradient at the 0-90 cm depth layer, were measured through the use of neutron probes and mercury manometers, respectively. The dry season results a water stress throughout the growing cycle, resulting in a low yield (548 Kg/ha). In contrast, the large amount of rainfall that occurred during the wet season, was sufficient to avoid water stress to the plant root system, leading to a significant increase in the crop yield, (1014 kg/ha). The evapotranspiration component has been estimated as 3,57 mm/day and 4,07 mm/day, respectively. (author)

    Bio refineries have been identified either as an alternative to oil refineries or as a supplement. This work seeks to understand these plants applied to the Brazilian case, which has in the alcohol-sugar sector a large number of lignocellulose material (sugar-cane bagasse) produced in large scale as a residue of the process of sugar and alcohol production. In this case, technological routes that are able to use this product as a basic feedstock for the industrial process will be described. Therefore, a model based on a set of economical and technological variables is applied to the routes. In this model, different profiles of bio refinery plants are described and compared with different hypothetical regions, which are characterized by a combination of both access to different amounts of raw material and different types of consumers. Overall, this work describes a model of both location and competition of the main bio refinery technological routes in Brazil that have the sugar-cane bagasse as the basic raw material. (author)

    The portion of Brazilian continental margin located between the Pernambuco Shear Zone (ZCPE) and Touros High, enclosing Natal Platform and Paraiba basin, NE Brazil, presents a thin sedimentary cover represented by Neo- Cretaceous deposits, over an elevated basement. In this zone the narrow platform ends abruptly against the ocean plate, forming a scarped slope. This area corresponds to the Transverse zone of Northeast Brazil (TZN) limited by two extensive transcurrent E-W shear zones that acted as accommodation zones for the strain produced by the advance of the southern and northern rift branches. During the Aptian, the rift suffered a NE deflection and contoured the Borborema Province and the TZN. The resistance of this block to the rift advance generated a prominent and elevated region into the Atlantic gulf which resulted in the absence of rift deposition over the Brazilian margin and its deviation to the African side. The model suggested by this paper denominates this area as the 'exception zone' of the Brazilian margin, which possess a poor petroliferous potential and need to be separated from the sector corresponding to the Pernambuco basin, located to south of ZCPE, representing the last piece of margin before the rift deflection and possessing an important petroliferous potential.

    Radioactive pollutants can cause impact on the environmental quality of soils and pose a risk to human health. The release of radioactive materials through nuclear testing or nuclear accidents cause the deposition of radionuclides on the ground,· it may be leached by rain, transported to the sources of natural waters and absorbed by the soil fauna and flora, and thus enter the human food chain. Radioecological studies have shown that soils with low pH, low organic matter content and low fertility are more vulnerable to contamination by {sup 137}Cs, since the transfer to plants is high. In this study, we aimed to assess and map the vulnerability to contamination by {sup 137}Cs surface horizons of the soils from the Pantanal and propose mitigation measures adapted to the regional scenario to optimize radiological protection of agricultural areas. Therefore, selected soil profiles located in the municipality of Jaraguari, state of Mato Grosso do Sul, and applied the conceptual model developed by Picanco Jr (2012), which was used in the reference values of the factor of soil-plant transfer (FT) for {sup 137}Cs in corn, related soil variables (pH, CTC and exchangeable K) and relevance of parameters and variations of amplitudes for each value range of FT. The application of this conceptual model established to detect the vulnerability of soils to radioactive contamination generated maps vulnerability showing that the region is very heterogeneous as this criterion, showing low levels of vulnerability for most of the region and in some areas, extreme vulnerability. This result identified the Pantanal as one of the less vulnerable to the radioactive contamination, but the sparse areas of extreme vulnerability can lead to contamination of subsoil and a significant spread of contamination via groundwater. This conceptual model, which defines vulnerability classification, is a first step for the study and determination of a numerical index of vulnerability to {sup 137}Cs soil and can be used in the task of remediation in case of rural areas by accident and {sup 137}Cs contamination establishing geographic areas where we should prioritize treatment due to a greater vulnerability.

    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)

    Full Text Available Pouco mais de dez anos depois da apresentação do projeto de lei que institui a parceria civil entre pessoas do mesmo sexo, neste artigo são reunidas reflexões, no âmbito do debate teórico e político, sobre as relações afetivo-sexuais entre homossexuais como uma expressão da diversidade da instituição social família. O ponto de partida é que o vazio jurídico relativo aos direitos conjugais e parentais de gays e lésbicas é uma expressa negação de sua condição de cidadãos. Procura-se mostrar que a vivência de relacionamentos amorosos e sexuais, algo que nos faz intrinsecamente humanos, ainda é, em termos legais, uma prerrogativa heterocêntrica, marca da injustiça erótica e da opressão sexual que atinge gays e lésbicas no Brasil e na maior parte do planeta.Ten years after the presentation of the project of law that institutes the civil partnership between same-sex people, this article is a collection of reflections about the theoretical and political debate regarding relationships between homosexuals as an expression of diversity of family institution. The lack of legal rights for gay and lesbian partners and parents is an explicit denial of their citizenship. It will be shown that amorous and sexual relationships, that make us intrinsically humans, is still, in legal terms, a heterocentric possibility, which is an expression of the erotic injustice and sexual oppression that affect gays and lesbians in Brazil and most of the world.

    According to the development of the agriculture business in the Midwest of Brazil, it can be noted that the cultivated land has imposed to the right of way pipeline weight and quantity increasing of vehicles moving above TRANSPETRO pipelines. This paper has the objective promoting discussions about this theme, presenting preceding conclusions when analyzing pipeline stresses, when the pipeline equipment are submitted to great loadings of agricultural machines. In order to execute this analysis, analytical formulations were used to compute static and dynamic loadings. These evaluations were referenced from API RP 1102 american norm. Many loading simulations, with different operating and environment configurations to the buried installations, were realized. These data were applied having the purpose of diagnosing typical situations existing in automated cultivated land crossings, related to OSBRA (Oleoduto Sao Paulo - Brasilia) right of way pipeline.

    In the current context to encourage sustainable development, wind energy plays an important role in the spread of renewable energy sources. In this paper, the possibilities and difficulties of wind power integration in large-scale are evaluated, specifically in the northeastern region of Brazil. From the seasonal complementarity with the water source, scenarios are set out where the maximum participation of only these two sources in the energy supply of the region is sought. Aiming to evaluate the possibilities of a completely sustainable regional energy supply, the northeast subsystem is isolated, excluding, in principle, imports and exports. Therefore, the energy storage capacity of reservoirs in the region is used as a key factor, combined with the seasonal availability of data sources and the annual energy consumption of the region.

    Biomass Integrated Gasification Combined Cycle (BIGCC) was identified as an advanced technology with potential to be competitive for electricity generation. The BIGCC technology uses biomass and the sub products of some industrial sectors processing, like sugar cane, as feedstock. The current Brazilian energy matrix is mainly based on renewable generation sources, making it important to assess these gasification technologies in the production of sugar, ethanol and electricity. In this work, a technical evaluation of the technologies incorporated in BIGCC power plants is done: the gasification process and the combined cycle power plant. On the other hand, the generated costs of these systems are analyzed, and the potential for implementation in Brazil plants from sugar cane bagasse is studied, in which a 10% increase in efficiency is obtained.

    Radioactive lightning rods were manufactured in Brazil until 1989, when the licenses for using radioactive sources in these products were lifted by the national nuclear authority. Since then, radioactive devices have been replaced by Franklin type one and collected as radioactive waste. However, only 23 percent of the estimated total number of installed rods was delivered to Brazilian Nuclear Commission (Comissao Nacional de Energia Nuclear - CNEN). This situation is of concern as there is a possibility of the rods being discarded as domestic waste, considering that in Brazil, 63.6 percent of the municipal solid waste is disposed at uncontrolled garbage dump, according to Instituto Brasileiro de Geografia e Estatistica (IBGE) in 2000. In addition, americium, the most common employed radionuclide, is classified as a high toxicity element, when ingested or inhaled. In the present study, it was performed migration experiments of Am-241 by lysimeter system in order to evaluate the risk of contamination caused by radioactive lightning rods disposed as a common solid waste. Sources removed from lightning rods were placed inside lysimeters filled with organic waste, collected at the restaurant of Instituto de Pesquisas Energeticas e Nucleares, IPEN-CNEN/SP, and the generated leachate was periodically analyzed to determine its characteristics such as pH, redox potential, solid content and concentration of the radioactive material. Microbial growth was also evaluated by counting the number of colony forming units. The equivalent dose to members of the public has been calculated considering the ingestion of drinking water, the most probable mode of exposure. The final result was about 145 times below the effective dose limit of 1 mSv.year-1 for members of the public, established by the International Commission on Radiological Protection (ICRP), demonstrating that the risk caused by lightning rods disposed at uncontrolled garbage dump is low.

    Full Text Available Many soils of the highlands of Serra do Mar, as in other mountain ranges, have thick histic horizons that preserve high amounts of carbon. However, the age and constitution of the organic matter of these soils remain doubtful, with possible late Pleistocene or Holocene ages. This study was conducted in three profiles (two in grassland and one in forest in Serra da Igreja highlands in the state of Paraná. We performed δ13C isotope analysis of organic matter in soil horizons to detect whether C3 or C4 plants dominated the past communities and 14C dating of the humin fraction to obtain the age of the studied horizons. C3 plants seem to have dominated the mountain ridges of Serra da Igreja since at least 3,000 years BP. Even though the Serra da Igreja may represents a landscape of high altitude grasslands in soils containing organic matter from the late Pleistocene, as reported elsewhere in Southern and Southeastern Brazil, our results indicate that the sites studied are at least from the beginning of the Late Holocene, when conditions of high moisture enabled the colonization/recolonization of the Serra da Igreja ridges by C3 plants. This is the period, often reported in the literature, when forests advanced onto grasslands and savannas.Muitos solos dos picos da Serra do Mar, como em muitas outras serras, apresentam horizontes hísticos espessos com elevados estoques de carbono. No entanto, a idade e constituição da matéria orgânica destes solos ainda é pouco conhecida e não se sabe se é predominantemente proveniente de comunidades de plantas do final do Pleistoceno ou do Holoceno. Este estudo foi realizado em três perfis, dois em campos altomontanos sobre Organossolos (1.335 m s.n.m e um em um colo (ponto de sela, onde a floresta altomontana sobre Gleissolos alcança seu patamar mais alto (1.325 m s.n.m.

Esta pesquisa teve como objetivo identificar a similaridade de variáveis determinantes da qualidade das águas do trecho perenizado da bacia do Curu, Ceará, durante a estação seca e chuvosa, pelo emprego de análise multivariada. As amostras de água foram coletadas em sete pontos (georreferenciados, nos meses de janeiro, março, maio e agosto de 2005, totalizando 28 amostras. Nas águas, foram analisados os seguintes atributos: pH, CE, Ca2+, Mg2+, Na+, K+, Cl-, CO3-, HCO3-, SO4-, PO4(3-, NH4- e NO3-. Quatro grupos homogêneos foram identificados, sendo estes independentes da posição geográfica dos pontos de coleta, demonstrando a maior influência da sazonalidade na definição da similaridade da qualidade dessas águas. Os valores da RAS (Razão de Adsorção de Sódio definiram a dissimilaridade do grupo 1 em relação aos demais; já o grupo 2 foi definido pelo nitrato e fósforo; enquanto que os valores da Condutividade Elétrica (CE e da RAS, os íons sódio e o cloreto determinaram a dissimilaridade entre os grupos 3 e 4. Embora as águas dessa área sejam inadequadas ao consumo humano, CE>0,5d Sm-1, o cloreto e o sódio não representam riscos à saúde humana. Com relação aos parâmetros determinantes para irrigação, em apenas um grupo a salinidade apresentou restrição ligeira a moderada, enquanto a RAS apresentou a mesma restrição em todos os grupos.A special attention should be devoted to the water quality determinant factors, since the water supply has been decreased each year.

Esse estudo constatou que a relação entre Lysimaco Ferreira da Costa e pessoas pertencentes ao grupo católico deu-se mais por questões políticas, do que por vias religiosas. Pelo que se apreende do estudo de sua sociabilidade, pode-se dizer que conservou, em seu círculo de amizades, católicos, protestantes e pessoas de crenças diversas, desde que essas não se opusessem, diante de circunstâncias de tomada de decisão e partido, aos seus interesses políticos. Palavras-chave: Lysimaco Ferreira da Costa; intelectuais da educação; ensino secundário.   LYSIMACO FERREIRA DA COSTA AND SECONDARYEDUCATION IN BRAZIL Abstract This article presents the insertion of Lysimaco Ferreira da Costa in the discussions concerning the direction of Brazilian education. He was an intellectual born in the state of Paraná. The period of the analysis ranges from 1920 and 1930 and its focus is the discussion of the secondary school. It emphasizes the ties and connections established in Lysimaco Ferreira da Costa’s network of relationships, his associations with intellectuals of other states, mainly from Rio de Janeiro and São Paulo. Through the data obtained in this study, it is possible to say that the affiliation between Lysimaco Ferreira da Costa and the Catholic group took place primarily due to political reasons rather than religious grounds. According to the study of his sociability, he maintained in his circle of friends both Catholics, Protestants and people of several beliefs, as long as they did not oppose to his political interests

    The aim of this work was to estimate the incident air kerma of lateral (LAT) and anterior-posterior (AP) together with posterior-anterior (PA) projection chest X-ray exams in one of the largest pediatric hospitals in Brazil. Dosimetric results are accompanied with the detailed analysis of patient characteristics and radiographer strategy. The exams of 225 (119 male and 106 female) patients were studied and 389 X-ray exams (200 AP/PA projections and 189 LAT projections) of pediatric patients were acquired. Patient thickness can be restored from age, height or weight with the uncertainty of ∼20-30%. Very slight correlation between the patient dose and thickness was observed with the difference in dose for patients of the same thickness reaching 4 times. By standardization of radiological protocols, it should be possible to keep dose within the intervals 50-100 μGy for LAT projection and 40-80 μGy for AP/PA projection. The dose values are lower than those recommended by major European guidelines to good practice. (author)

    The Instrument Calibration Laboratory (ICL) of the Instituto de Pesquisas Energeticas e Nucleares (IPEN/CNEN-SP), Sao Paulo, SP, Brazil has developed some work in order to establish a primary standard system for low energy X-ray employing a ionization chamber of free air. For this, one of the most important steps is the determination of factors of correction of its answer. Simulation is a frequently used tool for this because some correction factors can not be determined experimentally. For the correct simulation of these correction factors is necessary some input parameters such as geometry, the material composition of the dosimeter, the experimental arrangement and the radiation source are specified correctly. For the ionization chamber available on the LCI, the geometry, the material components and the experimental arrangement can be obtained easily. On the other hand, spectrum of radiation energy source, which must be inserted into the computer code has not been obtained. Thus, this study aims to determine this radiation spectrum, thus enabling the characterization of the new primary standard for low power X-radiation of ICL.

    Before the beginning of PROALCOOL in 1975, the first effective program in the world using biomass in large scale as an automotive fuel, sugar/alcohol industries already used sugar cane bagasse - a by-product of sugar/alcohol production - to generate energy for sugar production. Currently, besides the fact that they are self-sufficient in thermal/electrical energy, sugar/alcohol industries produce small electricity excess which is exported to local utilities. Gasifier/gas turbine systems are more advanced technologies which are being developed and shall be commercialized in eight to ten years approximately, presenting much higher efficiency, at low cost and inducing more exportable electricity. In this study, possibilities of gasifier/gas turbine systems are evaluated and projections of bagasse based electricity production are presented, until year 2010, for Sao Paulo state and Brazil. Generation costs of gasified bagasse based electricity are calculated: they shall be lower than electricity cost from fossil origin. Influence of electricity sale on the reduction of alcohol production cost are also evaluated for several opportunity costs of bagasse. Environmental and social impacts are analyzed, including evaluation of the cost of avoided carbon, related to the substitution of fossil fuel by sugar cane bagasse in thermoelectric power plants.

    The goal of the work presented in this paper is to provide necessary thermal hydraulics information to the design of an experimental installation to investigate the Pressurized Thermal Shock (PTS) to be implemented at Centro de Desenvolvimento da Tecnologia Nuclear (CDTN/CNEN). The envisaged installation has a test section that represents, in a small scale, a pressure vessel of a nuclear reactor. This test section will be heated and then exposed to a PTS in order to evaluate the appearance and development of cracks. To verify the behavior of the temperatures of the pressure vessel after a sudden flood through the annulus, calculations were made using the RELAP5/MOD 3.2.2 gamma code. Different outer radiuses were studied for the annular region. The results showed that the smaller annulus spacing (20 mm) anticipates the wetting of the surface and produces a higher cooling of the external surface, which stays completely wet for a longer time.

    Full Text Available This research aimed to describe the frequency of parasites in stool samples in the environment of Ilha da Marambaia, Rio de Janeiro, Brazil. One hundred and five stool samples were collected and processed by the coproparasitological techniques ethyl acetate sedimentation and centrifuge-flotation using saturated sugar solution. Parasites were detected in 81.9% of the samples, hookworm being the most prevalent, followed by Trichuris vulpis. Ascaris sp. eggs were also found. A high level of evolutive forms of parasites with public health risk was found in stool samples of the environment studied. We propose that health education programs, allied to an improvement of human and animal health care, must be employed to reduce the environmental contamination.

    Full Text Available A floristic survey of climbing species in a Caatinga fragment in the municipality of Porto da Folha, state of Sergipe, Northeast Brazil, was conducted to determine their survival strategies during unfavorable seasons. Forty-five angiosperm species belonging to 29 genera and 14 families were counted. Species richness was higher than that recorded in other Caatinga areas. The most representative families were Convolvulaceae (8, Fabaceae (6, Apocynaceae (5, and Dioscoreaceae (5. Most of the climbers (64.4% were herbaceous.

    Buriti (Mauritia flexuosa L.), a typical fruit from the Northeast and Center-West Amazon of Brazil, is used in many regional dishes. It is considered an excellent source of carotenoids that are A vitamin precursors, showing a majority of beta-carotene. It also presents ascorbic acid and sugar contents. Many studies have indicated that the lack of A vitamin is the main cause of night blindness and xerophthalmia. Also, ascorbic acid deficiency may cause scorbutic disease. The use of food irradiation is growing and represents an economic benefit to agriculture through the reduction of post-harvesting losses while maintaining food nutritional quality. In this study, buriti in natura was treated with gamma irradiation with doses of 0.5 kGy and 1.0 kGy. The objective was to evaluate the irradiation effects on total carotenoids, ascorbic acid and sugars concentrations of buriti. The fruit was evaluated through the total carotenoids analysis, by spectrophotometry, and the carotenoids (alpha and beta-carotene and lutein), ascorbic acid and sugars were determined by high performance liquid chromatography (HPLC). The results showed that buriti is an excellent source of total carotenoids (44600 {mu}g/100 g). The irradiation of buriti with the dose of 0.5 kGy did not significantly change carotenoids and sugars contents. However, there was a reduction of ascorbic acid concentration with an increase of the dose, which may have been caused by irradiation or by intrinsic and extrinsic factors that alter ascorbic acid stability in food, converting ascorbic to dehydroascorbic acid, while keeping the C vitamin active form.

    Brazil is the largest producer and exporter of coffee in the world. The coffee bean is one of the main products of the Brazilian trade balance. Two species of coffee are the most economically important: the Coffea arabica L. and Coffea canephora Pierre is the largest representative of the Coffea canephora Pierre is the coffea conillon. Food irradiation is an area of research that aims to increase the shelf life of foods and controlling pests. This study aimed to verify the physicochemical variables of Arabica coffee and conillon were affected when exposed to doses of gamma radiation from cobalt-60. The samples were provided by Polo in Coffee Quality Technology, Federal University of Lavras - UFLA. The coffee samples were subjected to irradiation doses: 0 (control), 5 kGy and 10 kGy, a multipurpose irradiator of IPEN - Research Institute of Nuclear Energy and the University of São Paulo, at a rate of 7.5 kGy / hour. For irradiation the samples were vacuum-packed in appropriate packaging aluminised. After the process of irradiation the samples were stored at a temperature of 15 ± 1 deg C and relative humidity of 17 ± 1%. The following analyzes were performed: levels of total sugars, glucose, sucrose, caffeine, humidity, pH, total acidity, electrical conductivity and fibers. Analyses were performed 1, 30, 60 and 90 days after irradiation, and the results were submitted to analysis of variance and means were compared by Tukey test at 5%. It was observed that the analysis results of the samples irradiated with 5 kGy and 10 kGy showed values similar to the control. It was concluded that irradiation did not induce deleterious effects on arabica coffee seeds and conillon irradiated with 5 kGy and 10 kGy to 90 days after irradiation. (author)

    The objective of this study was to determine the solubility parameters (rapid and slow dissolution rates, rapid and slow dissolution fractions) metal particles present in a pile of sludge accumulated under exposure to weathering from the Cia Mercantil Inga, located at the Ilha da Madeira, Sepetiba Bay, Rio de Janeiro. Plant samples collected in the neighboring of the pile and bioindicators placed in the region and collected after some months indicated that the inhabitants of Ilha da Madeira have been exposed to trace elements such zinc, cadmium, mercury and lead, produced during the processing of zinc minerals (hemimorphite - Zn{sub 4}(OH){sub 2}Si{sub 2}O{sub 7}.H{sub 2}O, and willemite - Zn{sub 2}SiO{sub 4}). A static dissolution test in vitro was used to determine the solubility parameters using a simulated lung fluid (SLF), on a time basis ranging from 10 min to 1 year. The metal concentrations in the sludge samples and in the SLF were determined using Particle Induced X-rays Emission (PIXE). In conclusion, this study confirms the harmful effects on the neighboring population of the airborne particles containing these metals that came from the sludge. The solubility parameters obtained for Zn, Cd, Cr, Ni and Mn present in the rapid dissolution fraction in SLF were 0.945; 0.473; 0.226; 0.300 and 0.497, respectively, and the corresponding times for half life of dissolution of the rapid fraction were f{sub r} = 2.082 days; f{sub r} = 0.09 days; f{sub r} = 0.37 days; f{sub r} = 0.332 days ad f{sub r} = 0.99 days; for the slow dissolution fraction times were f{sub r} = 146.95 days; f{sub r} = 63 days; f{sub r} = 86.64 days; f{sub r} = 79.66 days and f{sub r} = 59.84 days. These values indicate that these metals present a moderate absorption level in SLF, and may be classified as M type, according to the International Commission on Radiological Protection (ICRP). The use of solubility parameters allowed a better description of the kinetic behaviour of the sludge in

    The shielding calculation methodology for radiotherapy services adopted in Brazil and in several countries is that described in publication 151 of the National Council on Radiation Protection and Measurements (NCRP 151). This methodology however, markedly employs several approaches that can impact both in the construction cost and in the radiological safety of the facility. Although this methodology is currently well established by the high level of use, some parameters employed in the calculation methodology did not undergo to a detailed assessment to evaluate the impact of the various approaches considered. In this work the MCNP5 Monte Carlo code was used with the purpose of evaluating the above mentioned approaches. TVLs values were obtained for photons in conventional concrete (2.35g / cm{sup 3}), considering the energies of 6, 10 and 25 MeV, respectively, first considering an isotropic radiation source impinging perpendicular to the barriers, and subsequently a lead head shielding emitting a shaped beam, in the format of a pyramid trunk. Primary barriers safety margins, taking in account the head shielding emitting photon beam pyramid-shaped in the energies of 6, 10, 15 and 18 MeV were assessed. A study was conducted considering the attenuation provided by the patient's body in the energies of 6,10, 15 and 18 MeV, leading to new attenuation factors. Experimental measurements were performed in a real radiotherapy room, in order to map the leakage radiation emitted by the accelerator head shielding and the results obtained were employed in the Monte Carlo simulation, as well as to validate the entire study. The study results indicate that the TVLs values provided by (NCRP, 2005) show discrepancies in comparison with the values obtained by simulation and that there may be some barriers that are calculated with insufficient thickness. Furthermore, the simulation results show that the additional safety margins considered when calculating the width of the

    The aim of this study is to describe interactions between hummingbirds and ornithophilous species at Serra da Bodoquena in midwest Brazil, with focus on flowering phenology and pollination of these plant species. In two habitats, gallery forest and semi-deciduous forest, data on flowering phenology of ornithophilous species were collected monthly over 14 months. In addition, data on morphology and floral biology, as well as visitor frequency and hummingbird behavior, were recorded. The studied community contained eight ornithophilous plant species and six hummingbird species. The ornithophilous species flowered throughout the year, and the greatest abundance of flowers was at the end of the rainy season and the beginning of the dry one. The herit huingbird Phaethornis pretrei and feales of Thalurania furcata, were the most similar in floral resource use. Acanthaceae is the most representative family of ornithophilous plant species in Serra da Bodoquena and, thus, represents the main food source for hummingbirds. Ruellia angustiflora is especially important because it flowers continuously throughout the year and is a significant food resource for P. pretrei, which is the main visitor for this plant guild.

Na década de 70, o ensino de epidemiologia passou por um crescimento em nível de pós-graduação. Os anos 80 foram marcados pela "epidemiologia social", que incorporava as ciências sociais e seus métodos; a segunda metade da década foi marcada pelo desenvolvimento das técnicas da bioestatística. No momento atual, a definição de diretrizes para o ensino da epidemiologia depende da reflexão acerca de vários pontos, entre os quais a reformulação ou extinção dos programas de residência médica em medicina preventiva, medicina social ou saúde coletiva; implantação de programas de mestrado e doutorado exclusivamente em ; oposição entre formação instrumental e formação teórica; e desenvolvimento de estratégias para o fortalecimento de novos grupos de docentes em instituições de ensino nas regiões mais pobres do país.

    Plastic solid waste has become a serious problem recently concerning environmental impact. In this scenario, preparation of polymers and composites based on coconut husk fiber would lead to a reduction on the cost of the final product. Additionally, it will reduce the amount of agribusiness waste disposal in the environment. In Brazil, coconut production is around 1.5 billion fruits by year in a cultivated area of 2.7 million hectares, but the coconut husk fiber has not been used much for industrial applications. Moreover, biodegradable polymers have attracted the attention of the most part of population, due to the environmental issues arising from the increasing use of polymeric materials of low degradability discharged as waste residue. Besides, when considering an application in the medical field, it is necessary that the products are sterilized and, ionizing radiation is widely used to sterilize medical and surgical devices. In this work, it was studied blends and composites based on two commercial polymers: poly (e-caprolactone), PCL, and poly (lactic acid), PLLA, and coconut fiber. Those polymers are biodegradable as well as biocompatible, so it is important to know the effect of ionizing radiation in these materials. Samples were irradiated with gamma rays from {sup 60}Co source and electron beam with radiation doses ranging from 10 kGy up to 1 MGy. The non-irradiated and irradiated samples were studied using several analytical techniques and characterization assays that allowed understanding their properties in order to enable their application as precursors for medical and surgical devices. Thermal stability of non irradiated and irradiated composites up to 100 kGy radiation dose is not affected significantly by the coconut fiber incorporation to the polymeric matrix. Acetylation of fibers was not effective in order to induce any interaction between fibers and polymeric matrix, as expected. That was verified by the slight reduction of stress strength

    Tc-99m is used for diagnostic imaging in nuclear medicine through SPECT technique. It is obtained by the elution of {sup 99}Mo/{sup 99m}Tc generators. During the elution process {sup 99}Mo can be extracted becoming a radionuclidic impurity. One of the quality parameters of the eluate is the radionuclidic purity, MBT (molybdenum break through), defined as the ratio between {sup 99}Mo and {sup 99m}Tc activities in the eluate. The North-American and European pharmacopoeias restrict the {sup 99}Mo content, respectively, in 0.015 e 0.1% and, according to the International Atomic Energy Agency (IAEA), the activity ratio at the moment of administration of the radiopharmaceutical to the patient, should not exceed 0.015%. In Brazil, the control of such parameter is not obliged in official regulations. Thus, the objective of this work is to evaluate the occurrence of {sup 99}Mo in {sup 99m}Tc eluates. It was initially optimized a methodology to determine the activity of {sup 99}Mo in eluate samples. Efficiency curves were obtained for a NaI (Tl) 8'' x 4'' scintillation detector installed at the In Vivo Monitoring Laboratory (LABMIV-IRD). The methodology has been validated through the measurement of a {sup 99}Mo standard liquid source calibrated at the National Metrology Laboratory for Ionizing Radiation (LNMRI-IRD). The samples analyzed in this work were gently supplied by 5 Nuclear Medicine Clinics located in the city of Rio de Janeiro. The activities of {sup 99}mTc and {sup 99}Mo in those samples have been measured respectively at the clinics and at the LABMIV. By applying a standardized methodology, the ration between the activities were calculated. The results show that 147 out of 174 samples presented {sup 99}Mo activities above the minimum detectable activity of the technique. On the other hand, only 2 out of 147 samples surpassed the MBT limit suggested by the IAEA and have been detected in samples eluted from generators of 750 mCi. In one of the

    Landscapes are mainly driven by river processes that control the dynamic reorganization of networks. Discovering and identifying whether river basins are in geometric equilibrium or disequilibrium requires an analysis of water divides, channels that shift laterally or expand upstream and river captures. Issues specifically discussed include the variation of drainage area change and erosion rates of the basins. In southeastern Brazil there are two main escarpments with extensive geomorphic surfaces: Serra do Mar and Serra da Mantiqueira Mountains. These landscapes are constituted of Neoproterozoic and early Paleozoic rocks, presenting steep escarpments with low-elevation coastal plains and higher elevation interior plateaus. To identify whether river basins and river profiles are in equilibrium or disequilibrium in Serra do Mar and Serra da Mantiqueira Mountains, we used the proxy (χ), evaluating the effect of drainage area change and erosion rates. We selected basins that drain both sides of these two main escarpments (oceanic and continental sides) and have denudation rates derived from pre-existing cosmogenic isotopes data (Rio de Janeiro, Paraná and Minas Gerais). Despite being an ancient and tectonically stable landscape, part of the coastal plain of Serra do Mar Mountain in Rio de Janeiro and Paraná is in geometric disequilibrium, with water divides moving in the direction of higher χ values. To achieve equilibrium, some basins located in the continental side are retracting and disappearing, losing area to the coastal basins. On the contrary, there are some adjacent sub-basins that are close to equilibrium, without strong contrasts in χ values. The same pattern was observed in Serra da Mantiqueira (Minas Gerais state), with stream captures and river network reorganization in its main rivers. The initial results suggest a strong contrast between erosion rates in the continental and the oceanic portions of the escarpments.

    annual averages of crude rates of incidence. The spatial correlation of groups (clusters) of new cases has been verified, through the Moran index, and from geographically referenced radiometric measurements obtained in the previous step, the correlation between the incidence of breast cancer and ionizing radiation levels was assessed by unconditional linear regression. The results were presented in two papers. In the first, radiometric surveys were conducted in 1.405 of the 1.636 (85,9%) census tracts sectors that make up the seven Sanitary Districts in the city of Goiania. In total 197.811 geographically referenced measures of the absorbed dose rate in the air were made, with a average of 29,85 ± 7,47 and amplitude from 9,17 to 629,88 nGy/h. From these values were estimated the average of annual effective dose and collective effective dose for outdoor environments, with values of 0,036 ± 0,003 mSv/year and 28,51 ± 11,68 man.mSv/year, respectively. The levels of exposure to external gamma radiation, found in the city of Goiania 28 years after the radiological accident with Cesium-137, are compatible with the values estimated by UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation). And the value of the annual average of effective dose in Goiania, is lower than in other places in Brazil, which have only 'background' of natural radiation outdoors. The results obtained in this study indicate that the dosimetric situation in Goiania does not present undue risk to people and the environment. In the second article, were identified 4.105 new cases of breast cancer, 2.233 in the study area and 1.286 (57,59%) of these geographically referenced. The annual average values of crude rates of incidence, considering the total numbers of cases and geographically referenced presented in the study area are, respectively, 102,91 and 71,86 new cases per 100.000 women. The crude rate of incidence in Goiania was 66,59 cases per 100.000, while in the

    Full Text Available Maize is among the most important crops in the world. This plant species can be colonized by diazotrophic bacteria able to convert atmospheric N into ammonium under natural conditions. This study aimed to investigate the effect of inoculation of the diazotrophic bacterium Herbaspirillum seropedicae (ZAE94 and isolate new strains of plant growth-promoting bacteria in maize grown in Vitória da Conquista, Bahia, Brazil. The study was conducted in a greenhouse at the Experimental Area of the Universidade Estadual do Sudoeste da Bahia. Inoculation was performed with peat substrate, with and without inoculation containing strain ZAE94 of H. seropedicae and four rates of N, in the form of ammonium sulfate (0, 60, 100, and 140 kg ha-1 N. After 45 days, plant height, dry matter accumulation in shoots, percentage of N, and total N (NTotal were evaluated. The bacteria were isolated from root and shoot fragments of the absolute control; the technique of the most probable number and identification of bacteria were used. The new isolates were physiologically characterized for production of indole acetic acid (IAA and nitrogenase activity. We obtained 30 isolates from maize plants. Inoculation with strain ZAE94 promoted an increase of 14.3 % in shoot dry mass and of 44.3 % in NTotal when associated with the rate 60 kg ha-1 N. The strains N11 and N13 performed best with regard to IAA production and J06, J08, J10, and N15 stood out in acetylene reduction activity, demonstrating potential for inoculation of maize.

In two habitats, gallery forest and semi-deciduous forest, data on flowering phenology of ornithophilous species were collected monthly over 14 months. In addition, data on morphology and floral biology, as well as visitor frequency and hummingbird behavior, were recorded. The studied community contained eight ornithophilous plant species and six hummingbird species. The ornithophilous species flowered throughout the year, and the greatest abundance of flowers was at the end of the rainy season and the beginning of the dry one. The herit huingbird Phaethornis pretrei and feales of Thalurania furcata, were the most similar in floral resource use. Acanthaceae is the most representative family of ornithophilous plant species in Serra da Bodoquena and, thus, represents the main food source for hummingbirds. Ruellia angustiflora is especially important because it flowers continuously throughout the year and is a significant food resource for P. pretrei, which is the main visitor for this plant guild.O objetivo deste estudo é descrever as interações entre beijaflores e espécies ornitófilas na Serra da Bodoquena na região Centro-Oeste do Brasil, com foco na fenologia de floração e polinização destas espécies vegetais.

As características morfométricas e delimitação da bacia e sub-bacias hidrográficas foram obtidas automaticamente pelo software Hidrodata 2.0. A área de drenagem encontrada foi de 6,981 km² e o perímetro de 14,864 km. De forma geral, constatou-se que a área estudada possui forma alongada, com baixa densidade de drenagem, relevo forte-ondulado e declividade média de 33,9%. Esses parâmetros possuem grande influência sobre o escoamento superficial e, conseqüentemente, sobre o processo de erosão, que resulta em perda de solo, água, matéria orgânica, nutrientes e microfauna, que podem vir a provocar o assoreamento e eutrofização dos corpos d'água. Quanto à orientação do terreno, pôde-se se constatar que 41% do terreno da bacia hidrográfica está exposto à face norte-oeste, e 33% de sua área total encontra-se sombreada. Para um estudo mais detalhado, procuraram-se caracterizar suas sub-bacias, onde cada uma foi analisada individualmente, concluindo-se que as cinco sub-bacias apresentam deficiência de densidade de drenagem e forma alongada. Em termos de declividade média, os valores variaram entre 29,6 e 40,4%, representando o relevo forte-ondulado.

    Full Text Available Trichomycterus dali, new species, is described from flooded limestone caves in Serra da Bodoquena karst area, State of Mato Grosso do Sul, Central Brazil. The new species is diagnosed by a unique character in the genus, the presence of conspicuous, ridge-like adipose folds lining dorsally throughout the body. Trichomycterus dali can be further distinguished readily from epigean congeners by the reduction of eyes and skin pigmentation (except for T. gorgona, and from remaining congeners (i.e., all hypogean plus T. gorgona by the total loss of eyes, not visible externally (except for T. sandovali and T. spelaeus. Other diagnostic features includes very long barbels, especially the nasal (99.3-143.5% HL and the maxillary (97.0-131.3% HL, pectoral-fin ray count reaching I,9 and a unique cranial fontanel with a conspicuous constriction on the meeting point of supraoccipital and the two frontal bones. The troglobitic status of the species is suggested by the presence of troglomorphisms on an advanced degree, especially the reduction of skin pigmentation, the total loss of eyes and the enlarged barbels. In addition, the presence of a well developed adipose fold in adults may indicate a distinctive adaptation acquired by neoteny to withstand the food scarce conditions of its hypogean habitat.

We described the changes of stroke mortality rates in the city of Sao Paulo (1996-2003 emphasizing intracerebral hemorrhage and cerebral infarction. We categorized mortality data by gender and 10-year age-strata from 30 to 79 years-old. For men, an annual reduction of all types of stroke (-3.9%, and of stroke subtypes as intracerebral hemorrhage (-3.0% and cerebral infarction was observed (-2.7% as well as, a decline of ill-defined stroke (-7.4%. For women, a decline was observed for all types of stroke (-3.3% and for ill-defined stroke (-12%. However, the switch of ill-defined cases to stroke subtype categories due to a better clinical diagnosis blurred a real decline of both cerebral infarction and intracerebral hemorrhagic stroke among women.O declínio da mortalidade pela doença cerebrovascular no Brasil é conhecido, porém há poucos dados sobre a evolução temporal dos dois principais subtipos, a hemorragia parenquimatosa e o infarto cerebral. As modificações temporais dos subtipos de doença cerebrovascular foram estudadas na cidade de São Paulo entre 1996 e 2003 por gênero e faixa etária decenal entre os 30 e 79 anos. Para os homens detectou-se redução anual para todo os tipos (-3,9%, para hemorragia parenquimatosa (-3,0%, para infarto cerebral (-2,7% bem como para os casos mal definidos (-7.4%. Para as mulheres somente houve variação significativa para todos os tipos da doença cerebrovascular (-3,3% e para os casos mal definidos (-12%. Concluindo, as taxas de doença cerebrovascular estão em queda, porém entre as mulheres devido à melhoria do diagnóstico clínico houve migração de casos mal definidos para casos bem definidos. Devido a isso não foi possível detectar declínio nas taxas de mortalidade pelos subtipos de doença cerebrovascular.

    Full Text Available Objective: To determine the prevalence and specific dengue coefficients of mortality in Brazil in the elderly population correlating the rates by male and female. Methods: Analytical ecological study with temporal trend of design. It was used as data sources Sistema de Informação Hospitalar, Sistema de Informação de Mortalidade and Instituto Brasileiro de Geografia e Estatística. The population corresponded to the elderly aged between 60 years to 100 attended at Brazilian public health system whom were diagnosed with dengue between 2008 and 2015. Results: The prevalence rates did not change in the general population between the years 2008 and 2015. There was a significant increase in the number of deaths from dengue. In the elderly group, the prevalence increased substantially, and the specific mortality analysis in this group showed higher values than the mortality of the general population affected by dengue. Conclusions: It is very important to underline studies on the involvement of dengue in elderly groups for the development of public politics and the creation of specific protocols for the diagnosis and treatment in that age group, considering the lack of scientific evidence to entail proper conduct in handling such patients

    Full Text Available ABSTRACT Restingas are extremely degraded, tropical sandy ecosystems and are poorly studied in terms of nutrient cycling. The present study aimed to evaluate litter dynamics in a forest dune at Restinga da Marambaia, RJ. Litterfall was collected monthly using two parallel transects installed 200 m apart from each other with 15 litter traps (0.25 m2, over two consecutive years. The litterfall was sorted into leaves, twigs, flowers, fruits, and refuse. Litter decomposition was evaluated by the ratio between litterfall and litter layer on the soil surface, which was estimated every four months by quadrats (0.25 m2 placed next to the litter traps. The average annual litterfall was low (6.8 t ha-1 year-1 , mostly constituted by leaves (70%, with the greatest deposits occurring during the rainy season. The decomposition rate was low (0.85 and the turnover time was long (439 days. This litter dynamic contributes to the nutrient economy.

    Full Text Available Aborda o impacto da malária no âmbito da modernização republicana, basicamente nas ferrovias, que asssumiram então o papel de integrar o território e operar a expansão simbólica e material da nação brasileira. Os cientistas destacados para debelar os surtos epidêmicos não se limitaram a realizar as campanhas. Fizeram observações sobre aspectos da doença, inclusive suas relações com hospedeiros e ambientes, contribuindo com novos conhecimentos e com a institucionalização, no Brasil, de novo campo que então se estabelecia nas potências coloniais européias: a medicina tropical. O artigo articula essas inovações - especialmente a teoria da infecção domiciliária - com as campanhas em prol de ferrovias e com estágio subseqüente no enfrentamento da malária no Brasil, nos anos 1920.The article explores the impact of malaria on infrastructure works - above all, railroads - under the republican drive towards modernization. Railways helped tie the territory together and foster the symbolic and material expansion of the Brazilian nation. The scientists entrusted with vanquishing such epidemic outbreaks did not just conduct campaigns; they also undertook painstaking observations of aspects of the disease, including its relations to hosts and the environment, thus contributing to the production of new knowledge of malaria and to the institutionalization of a new field in Brazil, then taking root in Europe's colonies: "tropical medicine." The article shows the ties between these innovations (especially the theory of domiciliary infection and the sanitary campaigns that helped the railways, which in the 1920s were followed by a new phase in Brazil's anti-malaria efforts.

    Full Text Available The aim of this study was to inventory the mayfly fauna, based on nymphal and alate stages, in Serra da Mantiqueira and in Serra do Mar, São Paulo State, as well as to present information about habitats used by the genera. Nymphs were collected in several streams and mesohabitats with a Surber sampler and the winged stages with light attraction methods, entomological nets, and Malaise traps. In all, eight families and 33 genera were recorded, representing a very significant portion of the Brazilian fauna (80% of families and 49% of genera. Furthermore, it was possible to identify 11 species, of which two are new records for the state: Tricorythodes santarita Traver and Caenis reissi Malzacher. Despite the high diversity recorded, the accumulation curves presented an ascending form, indicating an increase in the number of genera with additional sampling effort. The high richness found in these areas are in agreement with the high biodiversity of the Atlantic Forest biome and the sampling effort employed, which included the use of different methods, the collection of both nymphs and winged stages, and the sampling of a large area with diverse streams and habitats.

    2010-06-01

    Full Text Available A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belonging to 28 families, most of which from unconsolidated substrates, was identified. The shellmound species composition does not differ from the present-day composition. All recorded species are characteristic of a wide transition zone between the south of the states of Espírito Santo (21°S and Rio Grande do Sul (32°S. Thus, the data show little evidence of evolution in the composition, richness,and biodiversity distribution patterns of mollusks in the Rio das Ostras region. Likewise, a reconstitution of the paleoenvironment from the functional characteristics of the shellmound species indicates that the locality's geomorphology and climate remained largely unchanged in the last 4,000 years BP.

    The structure, mineralogy, geochemistry, and geological setting of the Pegmatite Limoeiro (Virgem da Lapa - MG) are presented. The country rock of this pegmatite is the Precambrian Macaubas quartz - biotite schist. The pegmatites of this region seem to be genetically related to the Coronel Murta granitoids which in the Streckeisen's diagram are scattered between granite and granodiorite. The structure of the Pegmatite Limoeiro is well displayed throught the quarring work and the following zones have been mapped: border zone, wall zone, intermediate zone, quartz core and the replacement bodies. A sample of twenty K,Na-feldspars specimens, collected according to the structure of the pegmatite, have been analysed for major elements and for Rb, Sr and Zr, using X-ray fluorescence spectrometry. Sequences of perthites from different zones, sampled all over the pegmatite, showed enrichment of Rb from the wall zone inward. This pattern supports the assumption that the studied pegmatite from Limoeiro crystallized in a restricted system from the contacts inward. The regional variation pattern of the ratios K/Rb and Rb/Ba seems to have metallogenetic implications as in other world pegmatite provinces. (Athor) [pt

    NORM is the acronym used to refer to naturally occurring radioactive materials. Besides being objects of study and monitoring such materials can be used as raw material or as by-products or waste of industrial activities. Oil and gas, mining and water treatment are examples of facilities that can handle NORM. In such cases, their concentration at significant levels from the perspective of environmental and occupational radiation protection may occur. This study aims to evaluate the presence of the natural radioactive {sup 238}U and {sup 232}Th series in the treatment of city water elements Pocos de Caldas - MG (water, materials and waste).

    The present study chemically characterized sediment samples from the Billings reservoir, Rio Grande tributary, in the Metropolitan region of Sao Paulo, by determining metal concentration and other elements of interest. The chosen chemical parameters for this characterization were Aluminum, Arsenic, Barium, Cadmium, Copper, Chromium, Iron, Lead, Manganese, Mercury, Nickel, Selenium and Zinco. These parameters are also used in the water quality index, with the exception of Selenium. The concentrations were determined through different analytical techniques such as atomic absorption spectrometry (FAAS, GFAAS and CVAAS), optical emission spectrometry (ICP OES) and neutron activation analysis. These analytical methodologies were assessed for precision, accuracy and detection and/or quantification limits for the sediment elements in question. Advantages and disadvantages of each technique for each element and its concentration were also discussed. From these assessments the most adequate technique was selected for the routine analysis of sediment samples for each element concentration determination. This assessment verified also that digestion in a closed microwave system with nitric acid is efficient for the evaluation of extracted metals of environmental interest. The analytical techniques chosen were equally efficient for metals determination. In the case of Cd and Pb, the FAAS technique was selected due to better results than ICP OES, as it does not present matrix interference. The concentration values obtained for metals As, Cd, Cu, Cr, Hg, Ni, Pb and Zn in the sediment samples were compared to Canadian Council of Minister of the Environment (CCME) TEL and PEL values.

    Primordial, or terrestrial natural radionuclides, are found in different amounts in the environment. In dwellings, an important dose increment is due to building materials, which contribute for both the external gamma dose from the radionuclides of the {sup 238}U, {sup 235}U and {sup 232}Th series and the natural {sup 40}K and the internal dose, due mainly to {sup 222}Rn inhalation. Once granitic rocks are widely used both as construction materials or structural flooring, those rocks can become an important dose source, depending on the content of concentrations of radioactivity, and the construction application. In this work, a database for granitic rocks of the crystalline shield of Parana (mainly in the Metropolitan Region of Curitiba, RMC), used in civil construction, was generated, evaluating in terms of radiological protection the external and internal dose increments, caused by the use of these materials. Also, possible correlations between the {sup 226}Ra activity concentration, the {sup 222}Rn exhalation rate, density, porosity and chemical composition (oxide content) in these samples had been studied. The external dose was assessed by gamma-ray spectrometry with High-Purity Germanium detectors, where the activity concentration of the radionuclides {sup 232}Th, {sup 226}Ra and {sup 40}K are the parameters used in dosimetric models (Dosimetric Indexes), which established limits in accordance with the form, amount and application of material of construction. For the calculation of the annual effective external dose it was assumed a room model with dimensions of 4 m x 5 m x 2:8 m and all walls internally covered with 2 cm thickness of granite and an annual exposure time of 7000 h as suggested by the European Commission of Radiological Protection for internal superficial coating materials. The internal exposure was assessed from the radon concentration in the air of the room model, simulated from the superficial exhalation rate of {sup 222}Rn. The exhalation rate was determined by the passive detection technique with the Solid State Nuclear Track Detectors (CR-39) and the sealed can technique, assuming a ventilation rate of 0.5 h{sup -1} and an annual exposure time of 7000 h. The results for this studies show that the annual effective dose ranged from (62 {+-} 3) {mu}Sv.y{sup 1} to (138 {+-} 1) {mu}Sv.y{sup -1} and the internal annual effective dose ranged from (0,39 {+-} 0,04) {mu}Sv.y{sup -1} to (70 {+-} 4) {mu}Sv.y{sup -1}. These values are below the maximum limit of 1 mSv.y{sup -1} suggested by the European Commission of Radiological Protection, meaning that the granitic rocks evaluated can be used without radiological implications since the considered scenario is obeyed. The values obtained for the contribution due to the internal dose ranged from 1 % to 78 % of the values obtained for the respective external dose showing the radon contribution varies strongly with the rock type. The results of the correlations between {sup 222}Rn superficial exhalation rate, {sup 226}Ra activity concentration, density, porosity and major oxides of the samples, showed that, in terms of influence in the emanation fraction of radon, the most important parameter is the density, due to low porosity and similarity in terms of chemical composition amid the studied samples.

    Full Text Available In the southern escarpment of the Serra da Mantiqueira, northeast geographic divider between the State of São Paulo and Minas Gerais, there was an environmental accident caused by the disruption of an adductor whose purpose is to lead the water from a reservoir located at an altitude of 1820 m to the machine house where there is an electric generator located at 750 m.  This accident resulted in the formation of a scar on the hillside forest, with removal of soil and vegetation. To reverse the erosion processes, a methodology was developed consisting of the use of four barriers (numbered I to IV formed by seedlings of Bambusa mutiplex (Lour., whose purpose was to divert the water runoff in order to provide the regeneration of native vegetation. Stalks of bamboo intercropped with Bambusa multiplex were used to contain debris in two gullies formed by erosion. The development of vegetation was monitored for 18 months and evaluated by the application of a Leopold Matrix composed of 5 points, which are: erosion, regeneration of vegetation, success of bamboo planting, installed conservation structures and functionality. The purpose of the matrix was to demonstrate the effectiveness of interventions using bamboo. The result of the classification matrix enabled the quantitative and qualitative classification of the interventions, resulting in five levels, where the barriers I, II and IV were considered to be of very high efficiency, and barrier III was considered to be of high efficiency. The contention of the gully was considered to be of medium to very high efficiency.

    Full Text Available Apresentamos uma história do desenvolvimento da Entomologia Forense no Brasil e uma avaliação do estado da arte e perspectivas. Esses estudos no Brasil iniciaram-se em 1908 com os trabalhos pioneiros de Roquette-Pinto e Oscar Freire, que notaram a grande diversidade da fauna de insetos necrófagos e a impossibilidade de aplicação direta de métodos desenvolvidos na Europa. Nas últimas duas décadas a Entomologia Forense tem avançado rapidamente no Brasil, mas ainda existem lacunas importantes no conhecimento, especialmente com relação à taxonomia, biologia e ecologia dos principais grupos de moscas e besouros necrófagos e também falta de integração entre os entomologistas e a polícia judiciária. Atualmente existem no Brasil mais de 20 pesquisadores desenvolvendo pesquisas relacionadas com Entomologia Forense e algumas dezenas de peritos criminais com treinamento nessa área, em quase todos os estados brasileiros. Neste trabalho são também apresentadas algumas diretrizes para políticas de desenvolvimento deste campo de pesquisas no Brasil.The history of the development of forensic entomology in Brazil, its current status and perspectives are reviewed. Those studies in Brazil began in 1908 with the pioneer works conducted by Roquette-Pinto and Oscar Freire, who noted the high diversity of the native fauna of necrophagous insects and the impossibility of direct application of the methods developed in Europe. In the last two decades, forensic entomology advanced rapidly in Brazil, but there still are some important limitations, especially in relation to the taxonomy, biology and ecology of necrophagous insects and the lack of interaction between researchers and police investigators. Today there are in Brazil over 20 researchers involved with forensic entomology and tens of police investigators with some training in this field. Guidelines for the development of this field of investigation in Brazil are also presented.

    Full Text Available Neste artigo apresentamos e discutimos os resultados parciais da investigação sobre a constituição do campo da sexologia contemporânea no Brasil, parte da pesquisa comparativa "Sexualidade, ciência e profissão na América Latina". Uma segunda onda sexológica surgiu no Brasil em finais dos anos 1970 no Rio de Janeiro, com um viés essencialmente clínico, e em São Paulo, com um viés educacional. A década seguinte marcou um período de institucionalização no qual são criadas as duas associações que hoje polarizam o campo em torno de uma sexologia mais eclética e multiprofissional e da chamada "medicina sexual", em geral dominada pelos urologistas. Discutimos os significados dessa polarização em termos das disputas profissionais subjacentes e das concepções de gênero implicadas em tais disputas.In this paper we present and discuss the preliminary results of an investigation on the constitution of the contemporary field of sexology in Brazil, which is part of the comparative research "Sexuality, science and profession in Latin America". A second sexology arose in Brazil in the late 70's in Rio de Janeiro, with an essentially clinical approach, and in São Paulo, with an educational approach. The following decade brought a period of institutionalization in which the two associations that nowadays dominate the sexological field were created. They represent the two main trends in modern sexology; a more eclectic and multiprofessional approach and the so-called "sexual medicine", dominated by urologists. We discuss the meanings of this polarization in terms of its underlying professional disputes and the gender assumptions implied in such disputes.

Estudos sobre a atividade geral de plantas medicinais na cicatrização vêm sendo realizados, sem especificar sobre qual das fases da cicatrização a planta atua. Neste trabalho a atividade cicatrizante e antiinflamatória do extrato etanólico das flores da C. officinalis cultivada no Brasil foi avaliada em feridas cutâneas de ratos Wistar, por meio de avaliação macroscópica e histológica. A atividade antimicrobiana do extrato e das frações hexânica e diclorometano também foi avaliada. A atividade antiinflamatória do extrato etanólico da calêndula foi atribuída à diminuição da exsudação serosa, da hiperemia, da deposição de fibrina e da hiperplasia epidermal, além de resultar em crostas mais delgadas e umedecidas. Observaram-se também aumento de colágeno no tecido de granulação e efeito antibacteriano. Assim, o extrato etanólico da calêndula atuou de forma positiva sobre a atividade cicatricial em feridas cutâneas de ratos, bem como apresentou atividade antibacteriana in vitro.Since ancient history medicinal properties are attributed to flowers of Calendula officinalis L. (Asteraceae, mainly concerning its healing activity. Studies about the general activity of medicinal plants in healing wounds have been conducted without specifying in which healing phase the plant acts. In this work, the anti-inflammatory and healing activity of the ethanolic extract of C. officinalis flowers cultured in Brazil was evaluated in cutaneous wounds of Wistar rats through macroscopic and histological evaluation. The antibacterial activity of the extract and dichloromethane and hexane fractions was also evaluated. The anti-inflammatory activity of calendula ethanolic extract led to a reduction in plasmatic exudation, hyperemia, fibrin deposition and epidermal hyperplasia, besides

    The coastal environment has been heavily altered by multiple environmental impacts of human activities, such as disposal of sewage from urban areas, the release of numerous chemical industries, agriculture and the flow of vessels, which can lead to accidental spills of oil and oil products, fuels and other products transported by sea. In this context, a means of determining concentrations of these potentially toxic substances in the sea water is the biomonitoring by means of different types of bivalves, which have been used by various researchers, in Brazil and other countries. With regard to bivalve mollusks, particularly mussels, their use in monitoring the marine contamination is mainly due to their wide geographic distribution, sessile habit and ability to concentrate toxic metals to 102-105 times in relation to the concentrations detected in water. In the present study, we employed the passive biomonitoring using the Perna perna bivalve mollusk with respect to the elements Br, Cl, K, Mg, Mn and V. These elements were chosen since they can be determined by INAA method (Instrumental Neutron Activation Analysis), by means of short irradiation which provides faster analyzes and also due to their importance from the standpoint of environmental or nutritional studies. The aim of this study was to evaluate the content of Br, Cl, K, Mg, Mn and V in samples of Perna perna mussels (Linnaeus, 1758: Mollusca, Bivalvia) collected in coastal regions of Sao Paulo subject to anthropogenic contamination (Ponta de Itaipu and Palmas Island, in Santos), comparing the values obtained in sites potentially impacted with the values of the control site in Praia da Cocanha, in Caraguatatuba.

Em seringais do clone IAN 873 foram determinadas a classe do solo, fertilidade, nutrição e produção de borracha seca. Grande parte dos seringais encontra-se em Latossolos extremamente ácidos com Al alto e N, P, K, soma de bases trocáveis e capacidade de troca de cátions baixos. Os teores de Ca e Mg variaram de médios a altos nos Latossolos e foram muito altos nos Nitossolos, correlacionando-se negativamente com a produção de borracha seca. A análise foliar detectou desequilíbrios nutricionais no que se refere aos baixos teores de N e K evidenciados pela correlação positiva significativa com a produção de borracha seca. A correlação significativa negativa entre a produção de borracha seca e os teores de Ca foliares, associados aos altos teores de Mg, sugerem a redução desses nutrientes nas adubações. Dos micronutrientes, apenas o Cu apresentou correlação positiva e significativa com a produção de borracha seca.The objective of this work was to evaluate the nutritional status of rubber tree plantations at Zona da Mata region, Minas Gerais State, Brazil, to contribute with fertilization programs.

    Brazil is the largest exporter and second largest producer of tobacco worldwide, according to the crop production of 2013/2014. The tobacco plant (Nicotiana tabacum L.) is used to manufacture all derivatives and the chemical composition of the resulting tobacco products varies with the type of tobacco leaves, how they are grown, the region where they are cultivated, the characteristics of preparation (compression, filter and paper) and the temperature variations resulting from the incomplete combustion of tobacco. Tobacco products are extensively used throughout the world, and the most consumed are cigarettes, cigars and narghile. The damaging effects that these products cause to human health are discussed globally, and many surveys are performed with the aim of relating the use of these products with various illnesses. There is a lack of information about the radiological characterization of the tobacco plant both in international and Brazilian literature. The objective of this study was to determine the concentration of radionuclides {sup 238}U, {sup 234}U, {sup 230}Th, {sup 22}'6Ra, {sup 210}Pb and {sup 210}Po, members from the {sup 238}U decay series, and the radionuclides {sup 232}Th and {sup 228}Ra members of the {sup 232}Th decay series in the varieties Burley and Virginia, which are the most cultivated in Brazil. Plants from these varieties were cultivated in pots with organic substrate and fertilizer and also acquired from the producers and analyzed by alpha spectrometry for U and Th isotopes and {sup 210}Po determination, and gross alpha and beta counting, {sup 228}Ra, {sup 226}Ra and {sup 210}Pb determination.

    When there is exposure to ionizing radiation, the probability of developing a stochastic effect increases, and one of the most feared stochastic effects is cancer. Calculations made from data obtained with the population of Hiroshima, showed that these effects have not dose threshold. So it is impossible predict that a specific dose value, will lead to damages and therefore, doses must always be limited. Medical exposures have contributed to the increase in dose received by the populations of countries like Brazil. This is because there was an increase in interventional procedures using ionizing radiation. What has concerned researchers since, many companies did not fit the standards of radiation protection. The proper use of personal protective equipment reduces the exposure of patients and professionals. Trained and knowledgeable of the rules are able to choose the shielding for each type of procedure. So we evaluated the knowledge and radiology professional practice, in protection of patients, who can not be removed from the environment in sinus X-rays and check if the training improves the quality of this service. It was concluded that there is deficiency in knowledge of the rules and failures in protection of patients, and that training with regard to radiological protection increases the level of theoretical knowledge of the professionals involved, and improve their practices with respect to protection, reducing the doses and minimizing the risks involved in medical exposures.

    In Brazil, the current production of nuclear energy is restricted to Angra I plant, a 657 MW pressurized water reactor, in operation since 1982. Among the eight units predicted in 1975 within the Brazil Germany nuclear agreement, only two have been effectively contracted, namely Angra 2 and 3. The nuclear alternative, likewise all other energy sources, is very much dependable on the assessment of their own benefits compared to the associated risks posed to the population and the environment. The main goal of this article is to provide information to enable the improvement of public acceptance of the use of nuclear energy in the country, by comparing risks associated with different sources as well as pointing out aspects related to risk perception by the public.

    There has been growing interest in the specific impacts of anthropogenic factors on the health of wildlife. This study examined hematology and serum chemistry status of a prominent carnivore, the maned wolf (Chrysocyon brachyurus), living in, on the boundaries to, or on adjacent farmlands to the Serra da Canastra National Park, Brazil. Twenty-eighty wolves were captured, and values were compared 1) between subadults (n=8 animals) and adults (n=20 animals), 2) males (n=12 animals) and females (n=16 animals), and 3) among wolves living inside the park (n=11), near the park border (n=11 animals), and in neighboring farming areas (n=6 animals). Age, gender, and wolf locations influenced (Pmaned wolves. More importantly, certain traits indicative of health are potentially compromised in wolves living in areas under anthropogenic pressure. These data lay a foundation for examining the influence of farming and local domestic species on disease susceptibility and fitness in the maned wolf.

    Full Text Available The ecology of anopheline species (Diptera, Culicidae was studied in the vicinity of the Serra da Mesa Reservoir, State of Goiás, Brazil. Climatic factors and frequency of anopheline populations were analyzed. Bimonthly human-bait and Shannon trap captures were conducted for 36 consecutive months (January 1997 through December 1999. A total of 5,205 adult anophelines belonging to five species were collected. Anopheles darlingi was the most frequently collected anopheline (61.4%, followed by An. albitarsis s.l. (35.4%, An. triannulatus. (2.5%, An. oswaldoi (0.4%, and An. evansae (0.2%. The water level and vegetation along the banks of the reservoir were crucial to the frequency of the various anopheline species. Climatic factors had a secondary influence. The reservoir's water-level stability, increased frequency of An. darlingi, and the arrival of gold prospectors were responsible for the increase in malaria cases.

    Full Text Available Este trabalho teve como objetivo avaliar a qualidade de castanhas-do-brasil beneficiadas e comercializadas em Rio Branco, Acre. Foram analisadas amostras das três marcas de castanha encontradas no mercado local quanto às variáveis: atividade de água, teor de umidade, contagem total de fungos filamentosos, quantificação de Aspergillus flavus e de A. parasiticus, bem como quantificação de aflatoxinas B1, B2, G1 e G2. As castanhas do comércio se encontravam com um teor de umidade e atividade de água adequados, o que pode ter sido responsável pela baixa contaminação por fungos e por aflatoxinas. Quanto a estas micotoxinas, as amostras estão de acordo com o recomendado pela Anvisa, podendo ser esta uma consequência da grande divulgação no Estado do uso de Boas Práticas no manejo da castanha.The goal of this paper was to evaluate the quality of Brazil nuts processed and marketed in the city of Rio Branco, in the state of Acre (Brazil. We analysed three samples for water activity, moisture content, total fungus quantification of Aspergillus flavus and A. parasiticus, as well as quantification of total aflatoxin, Afla B1, Afla B2, Afla G1 and Afla G2. The nut samples from the market showed an appropriate moisture content and water activity, which may have been responsible for the low fungus contamination and aflatoxin production. As to these mycotoxins, the samples were consistent with Anvisa's recommendations, which may be a consequence of good management of the nuts in Acre.

    The sand fly, Lutzomyia longipalpis, is the main vector of Leishmania infantum in the Americas, primarily occurring in areas of apparent anthropomorphic modifications in several regions of Brazil. Sand flies were captured using light traps. Out of all captured species, Lu. longipalpis numbers had increased within the park. We report the occurrence of Lu. longipalpis in an area of Atlantic Forest, possibly representing the first sylvatic population of Lu. longipalpis in an area absent of peridomestic captures, but with the risk of L. infantum transmission in the areas of Niterói and Maricá.

Widespread questions have been raised concerning the quality of services provided at birthing centers by obstetric nurses. The results of the current study were: 11.4% maternal transfer rate; 2.2% cesarean sections; 1.2% neonatal ICU admissions; and 1% 5-minute Apgar scores below 7. Delivery dystocia and the request for epidural anesthesia were the main reasons for maternal transfer, and respiratory distress was the main cause of neonatal ICU admission. Corrected neonatal mortality was 2 per 1,000 live births. The results at this birthing center did not differ significantly from those in a review of the international literature. The most striking finding was the low cesarean rate. Comparative studies and more comprehensive national data on low-risk gestations are needed.

    The environmental and energy gains with the use of milk cattle residues in the Lagoa da Prata, MG, Brazil are investigated. Nine farms were visited and a questionnaire was applied to obtain relevant energy and environmental data. The data from the field were correlated to the productive process of the cattle and the energy consumption. It was obtained, as the result of the field research, a generation average of 3 ton of residues a day, an electric energy average monthly consumption of 2.500 kWh, a set of energy intensive equipment and an daily consumption average of 27 m{sup 3} of water day. The use of the cattle residues can solve the problem of residues, effluents and several pollutants generated in the region and bring an energy gain with the production of biogas, that can be converted in energy.

Os estudos foram realizados com base na série ininterrupta de dados climáticos do período de 1984 a 2007. A duração do ciclo da cultura foi calculada pelo acúmulo de soma térmica e a disponibilidade de água avaliada pelo balanço hídrico da cultura, ponderando-se a distribuição da precipitação pluvial e a evapotranspiração da cultura. A probabilidade de redução de produtividade de grãos por deficiência hídrica foi estimada considerando-se a porcentagem de redução de produção de grãos a partir da ocorrência de deficiência hídrica nos diferentes estádios do ciclo de desenvolvimento no campo. Verificou-se que a cultura do milho é afetada pela distribuição da disponibilidade hídrica ao longo do ciclo, sendo que a maior probabilidade de perdas de produção por deficiência hídrica ocorre no estádio da antese-fecundação. As semeaduras mais tardias no período recomendado tendem a ocasionar menores riscos de obtenção de produtividade de grãos abaixo da média regional.This study aimed to estimate the average potential of production of the corn crop in consequence of the variation of the water availability and the planting performed at different dates within the recommended period for Guarapuava, Paraná State, Brazil. The study was conducted considering uninterrupted series of climate data for the period from 1984 to 2007. The duration of the crop cycle was calculated by the accumulation of the thermal sum and the availability of water evaluated by the water balance of the crop considering the distribution of the precipitation and the evapotranspiration of the crop.

    In Brazil, the expansion of agricultural areas causes several problems on natural resources. With the increasing occupation of the Cerrado region by agriculture, a series of environmental problems like deforestation, soil erosion and soil compaction are appearing and causing radical transformations in the natural landscape due to removing almost all native vegetation. The conventional tillage system (CTS) is considered an inadequate form of soil management for its frequently irremediable consequences of soil compaction and soil erosion, and the no till system (NTS) makes the maintenance of the soil conditions possible, letting them close to the natural environment, thus reducing rates of soil erosion. The objective of this work was to evaluate the efficiency of riparian forests in the retention of sediments originated for three different tillage systems, through the fallout {sup 137}CS redistribution technique, the Universal Soil Loss Equation (USLE) and some physical and chemical parameters that indicate the structural conditions of the soils of Goiatuba and Jandaia-GO. In the three areas, soil profiles were collected in three layers of 20 cm (0-20, 20-40 and 40-60 cm) at distinct points located along linear transects in the direction of the maximum slope until the riparian forest. In the riparian forest of each area, trenches were opened and soil was sampled to evaluate the activity of {sup 137}Cs and the physical and chemical parameters of soil. Detection of the activity of {sup 137}Cs was made with a gamma ray detector model (GEM-20180P, EG and ORTEC) connected to a multichannel analyzer. The comparison of averages was made using the Tukey test at 5% level of significance. The. results indicated that, the three soil tillage systems presented high rates of soil erosion and deposition of sediments and the riparian forest of the areas under CTS, NTS and pasture, located downstream received great amounts of sediments, and that only the riparian forest of CTS was

    Brazil, with its sensitive ecology and large rainforests, has a key role in the global environmental problem. Bavaria and Brazil have a long tradition of economic and scientific cooperation. For this reason, it appears logical that the 'Babitonga 2000' project was initiated by the Universities of Erlangen-Nuremberg and Univille, Joinville, in the southern province of Santa Catarina. There was also a regular exchange of scientists and students. Two research stations are operated in the bay of Baia da Babitonga and in the rainforest of Sao Bento do Sul. (orig.) [German] Im vorliegenden Band der Erlanger Forschungen wird ueber das interdisziplinaere bayerisch-brasilianische Umweltprojekt ''Babitonga 2000'' berichtet.

Bayern und Brasilien verbindet eine lange Tradition wirtschaftlicher und wissenschaftlicher Zusammenarbeit, die heute auf vielfaeltige Weise gefoerdert wird. Somit lag die vor einigen Jahren angebahnte Partnerschaft zwischen den Universitaeten Erlangen-Nuernberg und der brasilianischen Universitaet Univille in Joinville (in der Suedprovinz Santa Catarina) im beiderseitigen Interesse einer Forschungskooperation. Ueber das Projekt ''Babitonga 2000'' hinaus ist es zu einem regen Austausch von Wissenschaftlern und Studenten gekommen.

    In front of the global trend for developing new ways of energy that pollute less and are renewable, Brazil emerges as a major actor in the development and use of technology for the production of biofuels. In the context of the potential of semi-arid to produce some oil used in production, the Brazilian government is enabling the production of Northeastern region. The State of Bahia is the largest producer of castor oil from Brazil, with an estimated production of 102.8 thousand tonnes of grain in the season 2008/2009 (CONAB, 2009). The development of the sector depends on appropriate government actions to support their competitive sustainability, and encouraging the improvement of management techniques in all involved. In that scenario, the logistics contributes to the development of this sector through the supply chain management. One conclusion is that the competitiveness and sustainability of the supply chain of castor in the Semi-arid of Bahia practices depends on the adoption of integrated logistics, without which the current failures prevent the consolidation of governmental objectives defined.

Neste sentido, aplicou-se a EUPS para análise de uma bacia hidrográfica de médio porte, a bacia do Rio Paracatu. Em termos específicos, este trabalho visou o emprego da metodologia de cálculo automático do fator L, desenvolvido por Desmet & Govers (1996, com o suporte de um sistema de informações geográficas (SIG. Essa metodologia foi empregada na estimativa da erosão atual. Mapas temáticos existentes, juntamente com informações sobre solos, uso da terra, relevo e clima, foram utilizados para a obtenção de coberturas, que cruzadas no SIG, produziram mapas de erosão atual. Na estimativa da perda de solo, verificou-se que 67,2% da área total da bacia do Rio Paracatu ainda se encontram dentro da tolerância de perda de solo (inferior a 10 t.ha-1/ano. A adaptação do cálculo do fator de comprimento de vertente (L, seguindo a metodologia de Desmet & Govers (1996, que considera o fluxo acumulado, teve resultado satisfatório.

    Although Brazil has a large insolation potential, utilization of solar thermal energy is still limited to few applications, like residential and commercial water heating and drying of grains. However, there are in other countries more intensive applications, like electricity generation, industrial heat and fresh water production. The present work describes which are the other ways of using solar thermal energy that have been developed in the world, approaches the main technical aspects that affect its utilization, the perspective of increasing it in Brazil and its possible barriers and, finally, PETROBRAS' studies in this area, positioning itself as an Energy Company. The main solar thermal technologies currently used in the world are evacuated collectors, that work efficiently at temperatures up to 130 deg C, and concentrating solar technologies, that can reach the temperature of 1200 deg C. Among the latter, solar trough is the technology that is already considered mature, and near to become economically viable. Brazil, at the moment, has two technological challenges: development of national technology to manufacture high performance solar collectors, like evacuated collectors and solar troughs, and the development of thermal equipment to operate at temperatures under 120 deg C, like adsorption and absorption chillers and desalination towers, that can be economically competitive.

    This thesis proposes a methodological framework, called Strategic Biodiversity Risk Assessment (SBRA), within Strategic Environmental Assessment (SEA), as a way to efficiently incorporate the risks to biodiversity caused by accidental spills into the strategic levels of offshore oil and gas E and P decision-making process. Moreover, this approach can also indicate the exclusion (or postponement) of bidding areas with extreme environmental sensitivity, as well as the choices for environmental-friendly E and P technologies. In order to exemplify this methodological framework application, two case studies are presented, one of the offshore O and G development program in southern Bahia state, Northeast of Brazil, and other of the offshore development plan in Abrolhos region, Brazil.

    Full Text Available Resumo A possibilidade de o clima alterar o temperamento de pessoas não nativas de determinada região era crença difundida desde antes do descobrimento da América. As mudanças de ar, temperatura e alimentação, acreditava-se, poderiam contribuir decisivamente para a degeneração ou o florescimento das raças. No Novo Mundo, as raças negra, europeia e indígena foram mescladas, reconfigurando doenças europeias. Exploro neste artigo como, na avaliação do historiador Robert Southey, essa mistura de raças foi tida como bastante positiva, principalmente a do indígena com a do português, que gerava o mameluco. Os paulistas, que eram mamelucos, foram apresentados em History of Brazil como herdeiros do temperamento empreendedor português e da infatigabilidade indígena.

    2014-09-01

    Full Text Available This paper is supported by analysis and reflections on a concept of differentiated and essentially relational tourism which takes into account the complexity, diversity and contingencies associated with the local dynamics in the area of the Morro da Conceição, in the city of Rio de Janeiro, Brazil. The theoretical approach was based on the proposals of two authors: Symbolic Site of Belonging and Located Tourism of Hassan Zaoual and Geographic Area of Milton Santos. The empirical approach was developed in the light of the experiences of the Project Palacios do Rio, through participatory observations, interviews and secondary sources review. Elements and dynamics of Morro da Conceição were presented highlighting the historical context, heritage and daily life of residents and visitors of the site, and also conditions that enable the site for embracing Located Tourism. In conclusion we emphasize the importance of addressing human and social relations in tourism. Also, that the current dominant tourism industry, supported by superficial exchange and discrepant profit needs to give way to a kind of tourism that strengthens human and social values such as authenticity, solidarity, trust, empathy, curiosity and time for human relationship.

    Biodiversity corridors comprise a mosaic of land uses connecting fragments of natural forest across a landscape. Two such corridors have been established along the eastern coast of Brazil: the Serra do Mar and the Central da Mata Atlântica corridors, along which most of the coastal plains are restinga areas. In this study, we analyze the present status of the endemic and endangered terrestrial vertebrates of both corridors. We sampled 10 restingas in both corridors, recording species of amphibians, reptiles, birds, and mammals. Some restingas harbor a relatively large number of endemic species,and two main regions of endemism can be identified along the restingas of both corridors: the coastal restingas from northern Espirito Santo State to southern Bahia State (between Linhares, ES, and Tarancoso, BA), and the coastal region between the restingas of Maricá and Jurubatiba, Rio de Janeiro State. Six species of terrestrial vertebrates considered threatened with extinction are found in the restingas of Serra do Mar and Central da Mata Atlântica biodiversity corridors (Liolaemus lutzae, Formicivora littoralis, Mimus gilvus, Schistochlamys melanopis, and Trinomys eliasi). The region located between the restinga of Maricá and that of Jurubatiba is of special relevance for the conservation of vertebrate species of the restingas of the corridors because a considerable number of threatened species of terrestrial vertebrates are found there. We strongly recommend efforts to develop checklists of threatened faunas for the States of Espirito Santo and Bahia.

Visando compreender porque nos tornamos consumidores de imagens, procurou-se recuperar, a partir da própria historia do McDonald's, os acontecimentos econômicos, sociais, culturais, políticos, que teriam nos transformado em uma sociedade na qual "estar na imagem é existir". Embora trágica em seu sentido de fundo, essa perda da forma nos é compensada por imagens de diversão e felicidade que as marcas nos transmitem. Ao final, questiona-se o alcance global dessa promessa a partir de uma digressão sobre o Brasil: como a marca McDonald's nos fornece as imagens para uma certa constituição identitária; e o seu nome para um sentimento de permanência?

    Full Text Available Objetiva-se mostrar os fatores sócio-econômicos que têm sido identificados como os principais determinantes da situação nutricional de um país. Conclui-se que a renda é o fator isoladamente mais importante na determinação do estado nutricional, mas uma vez fixada esta variável, outros fatores - tais como extensão do sistema de atendimento de saúde, nível educacional, programa de alimentação - também desempenham um papel relevante. Procura-se avaliar, empiricamente, com base em pesquisas até agora realizadas, quais seriam os determinantes da situação nutricional para o Brasil. Evidencia-se a hipótese, esperada na literatura, de que a renda é o fator mais importante, e, dado esta, também no caso brasileiro surgem como fatores relevantes o acesso a serviços de saúde e saneamento. Em face disto, discutem-se algumas alternativas de uma política de nutrição, mostrando-se a magnitude da redistribuição de renda necessária para cobrir o hiato nutricional e debatendo-se o papel dos programas de alimentação e nutrição, na forma em que foram explicitados no Programa de Prioridades Sociais do atual Governo.It is proposed here to offer a general view of the social and economic factors that have been identified as the main determinants of a country's nutritional situation. The conclusion is reached that income, considered in isolation, is the most important factor in determining the nutritional condition, but once this variable is fixed, other factors such as the extent of the health attendance system, educational level, food and nutrition programs - also play an important part. An attempt is made impirically to decide, which are the determinants of the nutritional situation for Brazil, in the light of previous research. It becomes evident, as the literature leads one to expect that income is the most important factor, and once that is established as true for the case of Brazil too, there also appear as relevant factors ease

    Full Text Available O presente artigo apresenta pesquisa que estuda as consequências perceptíveis do processo de penetração dos fundos financeiros na educação superior no Brasil e, posteriormente, a emissão de ações de instituições de ensino diretamente na bolsa de valores. Entre os resultados observados encontra-se o rápido crescimento das instituições que adotaram tal estratégia. A forma mais visível desse crescimento é a compra de outras instituições e seu aperfeiçoamento, por meio da implantação de uma gestão mais profissionalizada. Tal processo tem propiciado o crescimento acelerado de algumas instituições, generalizando a educação como uma mercadoria, assim como a tendencial oligopolização da oferta. Conclui-se afirmando que é cabível falar-se em uma financeirização da educação, posto que é o setor financeiro que assume a hegemonia na educação privada no país.This paper presents a research on the noticeable consequences of the supply of private equities and venture capital in Brazilian Higher Education and of the subsequent going public of many teaching institutions. These are growing fast, mainly through the purchase of other schools, whose administration is professionalized. Such process has generalized both education as a commodity and the oligopolization of provision. It is thus possible to conclude that education has been financialized, since private education is nowadays hegemonic in Brazil.

In 1993, a population based study was launched in Pelotas, Southern Brazil. All 5,249 newborns delivered in the city's hospitals were enrolled, and sub-samples were visited at the ages of one, three and six months and of one and four years. In 2004-5 it was possible to trace 87.5% of the cohort at the age of 10-12 years. Sub-studies are addressing issues related to oral health, psychological development and mental health, body composition, and ethnography. Birth cohort studies are essential for investigating the early determinants of adult disease and nutritional status, yet few such studies are available from low and middle-income countries where these determinants may differ from those documented in more developed settings.Descrever aspectos metodológicos do estudo da coorte de crianças que podem ser relevantes para pesquisadores que estejam planejando investigações semelhantes.

    The Bolivia-Brazil Natural Gas Pipeline - GASBOL - begins in the city of Santa Cruz of La Sierra, in Bolivia, arriving in Canoas (RS), in Brazil, traveling an extension of 3.150 Km. Of this total, 2.593 Km are in Brazilian soil. In the kilometer 526+500m of the south spread, GASBOL crosses the reservoir of the Vocoroca's dam (COPEL), which had its operational level reduced, in face of the station of the droughts that usually reaches the area in the months of March to September. The lowing of the reservoir caused the turn of the course of Fojo River (Sao Joaozinho River) to its natural quota, forming a waterfall, whose hydraulic gradient caused the removal of the sediment and part of the foundation soil, discovering the pipe that was with space free from approximately 13 m of length. This paper discusses the solution adopted, as well as the several details of the recovery project, besides geotechnical and hydraulic studies and the aspects of safety of the Gas Pipeline. (author)

    The purpose of this study is to forecast the demand for jet fuel for the next years, by applying aggregate models. The relevance of this issue is evidenced by the strong growth of air transport in recent years and the growth prospects of the sector, especially regarding the evolution of the use of this modal in middle-income population classes, since the number of trips per capita in Brazil is still much lower than in developed countries. The key variables in the models' specifications proposed in this study are: Brazil's GDP, the activity level of the sector (measured in passenger-kilometers and ton-kilometers, respectively, for air transport of passengers and cargo) and energy intensity. Findings show that the demand for jet fuel is expected to grow by an average of 6-8% per year until 2020, under the assumptions of an average GDP growth of 4.7% per year and energy efficiency gains of 1% per year.

Os resultados obtidos mostram que na região Amazônica o ciclo anual do NDVI não é bem definido, visto que o máximo tipicamente ocorre em junho, dois meses após o período chuvoso, enquanto o mínimo se dá em dois períodos distintos: entre fevereiro e março e setembro e novembro. Na região central do Brasil, o cerrado apresenta um ciclo anual definido, com valores máximos de NDVI entre março e maio, e mínimos em setembro, final do período seco. Por outro lado, a vegetação das regiões da zona da mata nordestina e dos campos de Roraima apresentam um ciclo anual nítido, sendo que os maiores valores de NDVI ocorrem em junho e julho e os menores entre fevereiro e março, alguns meses antes do início das chuvas. No caso da região nordeste do Brasil, a caatinga mostra um ciclo anual bem definido, com um período seco marcante, sendo que os valores mais elevados de NDVI ocorrem entre os meses de abril e maio, que é o final da época das chuvas, e os menores em setembro e outubro.

    This paper aims to identify and to present mineralogical and chemical arguments that demonstrate the existence of bentonite levels in the Irati Formation, found in outcrops to the west Acegua in southern Rio Grande do Sul (Brazil). These levels are thin, on average 4 cm thick, large in area, and are composed of grayish-white to greenish massive clay stones that contrast, in the field, with the shales of the Irati Formation. The bentonite levels of the Irati Formation are predominantly composed of Ca-montmorillonite, which constitutes the fine matrix of the rock; and scattered primary or magmatic crystals not larger than very fine sand. Among the main primary minerals representative of volcanic setting, it is possible to identify β-quartz paramorphs, sanidine, biotite, zircon, apatite and ilmenite, in addition to quartz and feldspar shards (splinters). More rarely, fragments of meso and macrocharcoals are found within the bentonite layers, which contrast with the maturity and type of non-vegetal organic matter of the Irati shale. Therefore, the nature of the precursor volcanism is inferred on the basis of rock geochemistry and crystal chemistry of the neoformed montmorillonite in the bentonite levels. Both methodologies indicate that during this period the volcanic ashes that reached the Parana Basin were generated by volcanism of intermediate composition, which is in accordance with what is known about the Lower Choiyoi Volcanic Province manifestations, which were synchronous with the sedimentation of the Irati Formation in the Parana Basin.

    Full Text Available The number of HIV-infected people is an important measure of the magnitude of the AIDS epidemic in Brazil and allows for comparison with epidemic patterns in other countries. This quantity can be estimated from the number of reported AIDS cases, which in turn needs to be corrected for the distribution of reporting delays and under-recording of cases. These distributions are unknown and must also be estimated from the recorded dates, which were missed to the Brazilian National AIDS registry. This paper estimates the number of AIDS cases diagnosed by imputing the lost information based on an estimate of the pattern in registration delay until 1996. We first fitted a non-stationary bivariate Poisson regression model to estimate the pattern in reporting delay. In the subsequent steps these models were applied to impute new data, thus replacing the missing information, and to estimate the magnitude of the AIDS epidemic in the country. Model estimates ranged from 36,000 to 50,000 AIDS cases diagnosed in Brazil and still unreported. Therefore, the epidemic was 20 to 30% greater than known from the available information as of February 1999. To be useful to health policy-makers, the surveillance system based on officially reported AIDS cases must be continuously improved.O número de pessoas infectadas pelo HIV é uma importante medida da magnitude da epidemia de AIDS no Brasil, e permite a comparação com o padrão epidêmico de outros países. Essa quantidade pode ser estimada a partir do número de casos notificados de AIDS, que necessita ser corrigido pela distribuição do atraso da notificação e pelas sub-notificações. Essas distribuições são desconhecidas e devem ser estimadas a partir das datas registradas, que no Brasil foram perdidas. Neste artigo, estima-se o número de diagnósticos de AIDS, imputando as informações perdidas a partir da estimativa do padrão de atraso até 1996. Primeiro, ajustou-se uma regressão de Poisson

    Full Text Available Estrutura de capital é um tema ainda controverso em teoria de finanças. Desde a discussão entre a teoria tradicional, que defende a existência de uma estrutura de capital ótima que leva à maximização do valor da empresa, e a proposta por Modigliani e Miller (1958, que considera que o valor da empresa não é afetado pela forma como ela é financiada, diversos estudos empíricos têm sido realizados com o objetivo de identificar os fatores que explicam a forma como as empresas se financiam. Esta pesquisa analisa a estrutura de capital das maiores empresas que atuam no Brasil, investigando a relação entre o nível de endividamento e os fatores apontados pela teoria como seu determinante. O estudo é baseado em dados contábeis extraídos das demonstrações financeiras de empresas de capital aberto e de empresas de capital fechado. A técnica estatística utilizada no estudo é a regressão linear múltipla. Os resultados indicam que os fatores risco, tamanho, composição dos ativos e crescimento são determinantes da estrutura de capital das empresas, enquanto que o fator rentabilidade não é determinante. Os resultados, também, mostram que o nível de endividamento da empresa não é afetado pelo fato de ela ser de capital aberto ou de capital fechado.Capital structure is still a still controversial issue in finance theory. Since the discussion between traditional theory, which asserts the existence of an optimal capital structure that maximizes the firm’s value, and Modigliani and Miller’s theory (1958, which considers that the value of a firm is unaffected by how it is financed, many empirical studies have been carried out to identify the factors that explain how a firm finances itself. This research analyses the capital structure of the largest firms in Brazil and investigates the relationship between the leverage ratio and the factors indicated by theory as determinant.

A total of 98 taxa of palynomorphs was identified from 35 subsamples. Three radiocarbonic datings were obtained along a section of 115 cm depth, including the basal age of 4730 ± 50 yr BP. Pollen diagrams and cluster analysis were performed based on palynomorphs frequencies, demonstrating five distinct phases (SAP-I to SAP-V, which reflected different paleoecological conditions. The predominance of plants associated with grasslands in the phase SAP-I suggests warm and dry climate conditions. A gradual increasing of humidity conditions was observed mainly from the beginning of the phase SAP-III, when the vegetation set a mosaic of grasslands and Atlantic rainforest. Furthermore, the presence of some forest taxa ( Acacia-type, Daphnopsis racemosa, Erythrina-type and Parapiptadenia rigida-type, from the phase SAP-IV, is interpreted as an influence of the seasonal semideciduous forest in the study region.

    The Brazilian savanna, Cerrado, is the second largest biome over South America and the most floristically diverse savanna in the world. This biome is considered a conservation hotspot in respect to its biodiversity importance and rapid transformation of its landscape. The Cerrado's natural vegetation has been severely transformed by agriculture and pasture activities. Currently it is the main agricultural frontier in Brazil and one of the most threatened Brazilian biomes. This scenario results in environmental impacts such as ecosystems fragmentation as well as losses in connectivity, biodiversity and gene flow, changes in the microclimate and energy, carbon and nutrients cycles, among others. The Priority Areas for Conservation is a governmental program from Brazil that identifies areas with high conservation priority. One of this program's recommendation is a natural vegetation map including their major ecosystem classes. This study aims to generate more precise information for the Cerrado's vegetation. The main objective of this study is to identify which ecosystems are being prioritized and/or threatened by land use, refining information for further protection. In order to test methods, the priority area for conservation Chapada da Contagem was selected as the study site. This area is ranked as "extremely high priority" by the government and is located in the Federal District and Goias State, Brazil. Satellites with finer spatial resolution may improve the classification of the Cerrado's vegetation. Remote sensing methods and two criteria were tested using RapidEye 3A imagery (5m spatial resolution) collected in 2014 in order to classify the Cerrado's major land cover types of this area, as well as its land use. One criterion considers the Cerrado's major terrestrial ecosystems, which are divided into forest, savanna and grassland. The other involves scaling it down to the major physiognomic groups of each ecosystem. Other sources of environmental dataset such

    Full Text Available Este trabalho analisou as mudanças na estrutura de mortalidade da população do Estado de São Paulo, Brasil, entre 1980 e 2005, na tentativa de identificar os efeitos destas mudanças na variabilidade da idade à morte. As evidências de um deslocamento da distribuição de óbitos para as idades mais avançadas foram claras, pois o tempo médio de vida da população aumentou cerca de sete anos. Buscou-se analisar se esse deslocamento foi acompanhado por uma redução na variabilidade da idade à morte, o que daria suporte para o início de um processo de compressão da mortalidade. Dois períodos distintos de mudança na variabilidade da idade à morte foram evidenciados. No primeiro (1980 a 1995, identificou-se aumento na variabilidade da idade à morte. Já no segundo (1995 a 2005 reconheceu-se tendência de redução nessa variabilidade. Estimativas acima de determinado quartil da distribuição dos óbitos por idade indicaram que o processo de compressão da mortalidade ocorreu em quase todo o período. Destaca-se que as mulheres apresentaram variabilidade da idade à morte significativamente menor que os homens em todo o período analisado.In the present study, changes in the population mortality structure in the State of São Paulo, Brazil, were analyzed from 1980 to 2005, aimed at identifying the effects of these changes on the variability of age at death. Evidence of a change in the distribution of deaths toward more advanced ages was found, and the mean lifespan for the overall population increased by seven years during the period. Two different scenarios were observed. The first (1980-1995 showed an increase in the variability of age at death. The second (1995-2005 showed a downward trend in variability. Estimates beyond a given quartile of the death distribution by age indicated that compression of mortality took place throughout the entire period. However, variability of age at death was lower for males as compared to females.

    The determination of the hydraulic conductivity of a Red-Yellow Podzolic Soil was carried out during an experiment in a plot measuring 3.5 m x 3.5 m, at the Experimental Station of Itapirema, Goiania, in Pernambuco State, Brazil. The internal drainage method proposed by Hillel (1972) was used to obtain the hydraulic conductivity as a function of soil water content, K(θ), in the three characteristic horizons of the soil. Three neutron probes were used for measuring the humidity, that was determined by a calibration curve. Three characteristic horizons of the Red-Yellow Podzolic Soil were investigated for hydraulic conductivity. The sandy A horizon, with large pores, has a high conductivity while the B1t horizon, with a massive structure and few visible pores, has a low infiltration rate. The hydraulic dynamics of the B2 horizon is more complex due to its heterogeneity. (author). 79 refs, 17 figs, 11 tabs

    The opening of the Brazilian economy and the end of the state-owned oil company PETROBRAS monopoly made possible for national and international companies to become concessionaires of the rights and obligations regarding the exploration, development and production of oil and natural gas. The increasing of the oil reserves and production, together with the technological development and the more restricted environmental legislation, resulted in a gradual increased participation of the natural gas in the Brazilian domestic energy supply. Around 3% for many years, the participation of gas in the Brazilian domestic energy supply has increased to 7.5% in 2002, as mentioned in the 2003 Brazil Energy Balance (BEN). The 2003 production was more than 100 millions boe, and the import was more than 37 millions boe according to the National Oil Agency (ANP).

    Full Text Available We analyzed the alimentary tract of 66 specimens of Amphisbaena munoai Klappenbach, 1969 from the Serra do Sudeste, state of Rio Grande do Sul, southern Brazil. Forty specimens (60.6% had prey items in their gut. The diet consisted mainly of small invertebrate prey, such as termites, insect larvae and ants. The most abundant prey item was termites, found in 62.5% of the non empty stomachs. The high number of individual prey items in the majority of stomachs, the small size of the regular prey items, and the absence of gut content in specimens of A. munoai kept alive for about two days, indicate that this species forages very frequently. The predominance of fossorial prey items and the occasional records of nomadic ants lead us to suggest that A. munoai usually feeds underground, and occasionally forages on the surface.Analisamos o trato digestório de 66 exemplares de Amphisbaena munoai Klappenbach, 1969 procedentes da Serra do Sudeste do Rio Grande do Sul, Brasil. Quarenta espécimes (60,6% possuíam presas. A dieta é composta basicamente de pequenos invertebrados, como térmitas, larvas de insetos e formigas. As presas mais abundantes foram térmitas, encontradas em 62,5% dos estômagos não vazios. O elevado número de presas em cada indivíduo na maioria dos estômagos, o tamanho pequeno de presas regulares e a ausência de itens alimentares em espécimes de A. munoai mantidas vivas por aproximadamente dois dias, indicam que está espécie é forrageadora freqüente. A predominância de itens alimentares fossórios e o encontro ocasional de formigas nômades nos permitem sugerir que A. munoai usualmente se alimenta abaixo da terra e ocasionalmente na superfície.

    Full Text Available Neste artigo, faz-se uma análise epidemiológica descritiva da morbidade e da mortalidade por acidentes e violência no Brasil e suas capitais, em anos mais recentes para os quais as informações estão disponíveis. Usam-se dados dos Sistemas de Informações sobre Mortalidade e de Internações Hospitalares, do Ministério da Saúde; da Secretaria Nacional de Segurança, do Ministério da Justiça; e do Departamento Nacional de Trânsito, do Ministério das Cidades. Os dados populacionais de 2002 e 2003 são os disponibilizados pelo Datasus/MS. Destacam-se algumas situações que persistem no Brasil: elevadas taxas de homicídios e de mortes por acidentes de trânsito; concentração dos eventos na população jovem, negra e do sexo masculino; e a complexidade e multideterminação desses fenômenos. Como novo, aponta-se um processo de disseminação de homicídios para outros municípios das regiões metropolitanas e do interior dos Estados, com destaque para a magnitude da morbidade em relação à mortalidade. Porto Velho, Macapá, Vitória, Rio de Janeiro e Cuiabá apresentam os maiores indicadores de violência intencional - elevadas taxas de homicídios e de lesões corporais. Em Palmas ocorrem altas taxas de mortalidade por acidentes de transporte e de vítimas não fatais por 10 mil veículos.This article presents a descriptive epidemiological analysis of accidents and violence in Brazil and in the Brazilian capitals in recent years.

The authors emphasize some already known aspects: the high homicide rates and high death rates due to traffic accidents, the concentration of these events in the population of young black males and the complexity and multiplicity of determinants of these phenomena. The text points to a new scenery involving the spreading of homicides to neighbor communities of metropolitan areas and to the inner regions of the States. They further verify higher morbidity than mortality rates. It calls attention to Porto Velho, Macapá, Vitória, Rio de Janeiro and Cuiabá with the highest indicators for intentional violence - high rates of homicides and injuries - and to Palmas, with high death rates from traffic accidents and non-fatal victims per 10 thousand vehicles.Faz-se uma análise epidemiológica descritiva da morbidade e da mortalidade por acidentes e violência no Brasil e suas capitais, em anos mais recentes para os quais as informações estão disponíveis.

    Full Text Available The "Brazilian bill of rights for internet users," or "marco civil," has been under consideration at the brazilian congress since 2011. Marco civil's provisions for network neutrality have been particularly controversial. Proponents of network neutrality in Brazil advocate for the "equal treatment" of all data packets, including banning internet service providers from offering to content providers the option to purchase enhanced quality of service in the delivery of data packets. These network neutrality rules conflict with the other goals and principles of marco civil-particularly goals to promote internet access, to foster innovation, and to protect the constitutional right of freedom of speech and the free flow of information.A "carta Brasileira de direitos dos usuários da internet," ou "marco civil," tramita no congresso Brasileiro desde 2011. As disposições do marco civil relativas à neutralidade de rede são particularmente controversas. Os defensores da neutralidade de rede no Brasil advogam pela "igualdade de tratamento" de todos os pacotes de dados, inclusive proibindo que provedores de serviço de acesso à internet ofereçam aos provedores de conteúdo a opção de adquirir uma melhor qualidade de serviço na entrega de pacotes de dados. Essas disposições relativas à neutralidade de rede conflitam com outros objetivos e princípios do marco civil - especialmente os objetivos de promover o acesso à internet, promover a inovação, e garantir o direito constitucional de liberdade de expressão e informação.

    Full Text Available Este artigo tem como objetivo a análise de pesquisas sobre percepções de consumidores, produtores, cidadãos em relação ao uso de alimentos transgênicos, estabelecendo comparações entre as desenvolvidas no Brasil, na Europa, na Ásia e nos Estados Unidos. Tais pesquisas têm passado a desempenhar um papel central nos debates sobre seus riscos tanto entre os setores a seu favor quanto aos que se manifestam contrários a tal uso. Um dos argumentos centrais deste trabalho é que no Brasil há uma significante carência de dados sobre tal percepção pública. A falta de pesquisas, ou seu número limitadíssimo é aqui considerado uma evidência para caracterizar a trajetória da polêmica no Brasil, com uma significativa ausência de participação pública nos debates sobre transgênicos. Estes giram em torno de atores sociais organizados, que atuam sem ou com parcial representatividade. Também o número limitado de pesquisas expõe os limites da área de marketing, ainda assumindo no Brasil uma perspectiva positivista sobre o consumidor. E, por último, consideramos que podemos relacionar a falta de informação com a falta de problematização no espaço acadêmico sobre os conflitos ou consensos entre conhecimentos peritos e leigos quando estão em questão inovações tecnológicas que envolvem riscos incertos. Na primeira parte focalizamos nas pesquisas realizadas no contexto brasileiro, escolhendo as que passaram a ser destacadas como apóio a argumentos a favor ou contra os transgênicos entre os principais atores sociais envolvidos no debate. Na segunda parte consideramos as pesquisas realizadas em outros paises. Na terceira parte analisamos os limites e vantagens das diferentes pesquisas aqui selecionadas como representativas, o que nos permite nas conclusões formular sugestões para pesquisas de opinião pública no Brasil não só sobre transgenicos, mas também sobre percepção publica da ciência.This article has as its

    Full Text Available Este artigo tem como objetivo principal relatar as doenças registradas para a mandioquinha-salsa até a data presente e descrever sua situação atual no País. Na literatura, foram registrados para a cultura 27 gêneros de fungos, três de bactérias, doze de nematóides e cinco espécies de vírus. Destes, já foram relatados no Brasil treze fungos, e todos nematóides e bactérias, enquanto nenhum vírus foi oficialmente registrado, embora já tenham sido observadas plantas com sintomas típicos de viroses a campo. A maior parte dos registros estão na forma de resumos, capítulos de livros ou publicações genéricas, desprovidos de uma série de dados relevantes, como provas de patogenicidade, importância da doença, perdas, identificação mais acurada, entre outras. A cultura da mandioquinha-salsa ainda é tida como rústica, sendo poucas as doenças consideradas limitantes. O nematóide das galhas (Meloidogyne spp. e a podridão-mole pós-colheita causada por Erwinia spp. são os principais problemas atualmente, e causam perdas significativas. Também ocorrem com muita frequência manchas foliares causadas por Septoria, Cercospora e Xanthomonas campestris pv. arracaciae, e em algumas regiões podridão de plantas a campo causadas por Sclerotinia sclerotiorum e Sclerotium rolfsii. Como não existe nenhum produto químico oficialmente registrado para a mandioquinha-salsa no Ministério da Agricultura, Pecuária e Abastecimento, as medidas de controle passíveis de recomendação incluem ações preventivas, como o uso de material propagativo sadio (preferencialmente mudas pré-enraizadas de origem conhecida, a adoção de rotação de culturas, a eliminação de plantas ou partes doentes, e a adubação e a irrigação adequadas. O estudo sistematizado das doenças e o registro cuidadoso de surtos ou novas enfermidades para a cultura são importantes para subsidiar futuras medidas de controle.The diseases of arracacha that have already

O momento é muito propício a uma reflexão ainda maior sobre esta doença que é a principal causa de morte nas UTI, haja vista o elevado impacto econômico e social. Precisa-se cada vez mais desenvolver Campanhas de Sobrevivência na Sepse e fazer uso racional, baseado em evidências, dos recursos por ora disponíveis e da forma mais precoce possível.BACKGROUND AND OBJECTIVES: Sepsis represents the major cause of death in the ICUs all over the world. Many studies have shown an increasing incidence over time and only a slight reduce in mortality. Many new treatment strategies are arising and we should define the incidence and features of sepsis in Brazil. METHODS: Prospective cohort study in sixty-five hospitals all over Brazil. The patients who were admitted or who developed sepsis during the month of September, 2003 were enrolled. They were followed until the 28th day and/or until their discharge. The diagnoses were made in accordance to the criteria proposed by ACCP/SCCM.

Aurora 1 harvested in the Zona da Mata region of Minas Gerais in two ripening stages and kept under different storage temperatures. Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv. Aurora 1 harvested in the Zona da Mata region.

    Full Text Available Grapevine plants have been grown in different tropical regions of Brazil. In the state of Roraima, this culture was introduced commercially in 2005 in Boa Vista. Unlike temperate regions, tropical regions present thermal conditions for grape production throughout the year. To evaluate the climatic characteristics on different periods of the year, it can be used different indices. The objective of this study was to characterize climate suitability of Boa Vista, Roraima, Brazil, for grapevine cultivation at different months of the year. For climate classification it was used the Geoviticulture Multicriteria Climatic Classification System (CCM, which is composed by three indices: Heliothermal (IH, Cool Night (IF, and Drought (IS. It was also used the Zuluaga Index (IZ, to assess the risk of incidence of fungal diseases on the vine, especially in relation to the incidence of downy mildew (Plasmopara viticola, one of the main grapevine diseases in humid regions. Based on the evaluated indices, it was found that the most favorable period for grape production goes from October to March because of the lower values of rainfall. During the other months, it can be employed branch pruning without fruit production, as occurs in other tropical locations of Brazil. =A videira tem sido cultivada em diferentes regiões tropicais do Brasil. No estado de Roraima, ela foi implantada comercialmente em 2005 em Boa Vista.

Este município de população predominantemente indígena constitui uma importante noso-área da Amazônia para o problema da tuberculose, cuja magnitude se expressa por intermédio do coeficiente 2,4 vezes mais elevado que a média estadual e até quatro vezes mais que a média nacional. Análises estatísticas utilizadas para avaliar a tendência em relação à associação com a idade, o sexo e a forma clínica revelaram diferenças no comportamento da endemia, quando comparados os coeficientes de incidência entre os casos de procedência urbana e rural. As taxas padronizadas mostraram a população masculina com uma incidência mais elevada que a feminina nas duas áreas de residência. A faixa etária mais atingida foi acima de 50 anos, porém a proporção de menores de 15 anos se mostrou acima dos valores esperados na população geral do país, além de apresentar diferentes níveis de gravidade nas subáreas rurais estudadas. Os achados indicam que esta situação pode ser explicada pelas desigualdades, sobretudo, relativas à acessibilidade aos serviços de saúde que, contraditoriamente, parecem menos resolutivos na área urbana.This study describes the tuberculosis situation in São Gabriel da Cachoeira, Amazonas State, Brazil, from 1997 to 2002. The county, which has a predominantly Indian population, is a relevant tuberculosis area in Amazonas, since the infection rate is 2.4 to 4 times that of the overall State and national rates.

As atividades de vigilância nesses focos no período de 1935/2004 foram desenvolvidas sucessivamente pelo Departamento Nacional de Saúde, Serviço Nacional de Peste, Departamento Nacional de Endemias Rurais, Superintendência de Campanhas de Saúde Pública, Fundação Nacional de Saúde e finalmente pela Secretaria de Vigilância em Saúde. A análise dos dados levantados sobre a ocorrência de casos humanos nesses 70 anos permite identificar diferentes padrões de circulação da enfermidade na população humana, caracterizados pela alternância de momentos de elevadas incidências e de silêncio, possibilitando estabelecer uma periodização cronológica com características epidemiológicas próprias. Conclui-se desses resultados que a peste ainda deve ser considerada uma ameaça potencial, o que justifica revitalizar as ações de vigilância epidemiológica, o que só ocorrerá com o fortalecimento de todas as instâncias do Sistema Único de Saúde.After its introduction into the State of Ceará, Brazil, in 1900, the plague was established in seven ecological complexes: Chapada do Araripe and the Ibiapaba, Baturité, Machado, Matas, Pedra Branca, and Uruburetama mountains.

    There are around 15.000 workers in Brazil involved in the mining and milling processes of thorium bearing minerals. It is necessary to estimate the exposure of workers to airborne particulate containing thorium to estimate the risk associated with the inhalation of aerosols. The aims of this study were: - to develop a national cascade impactor and - to characterize the exposure of workers to airborne particulate containing Th in two plants and one industry that were chosen. Plant A and Pant B process niobium ore and industry C uses thorium nitrate to manufacture gas mantle. The national cascade impactor - ICN was developed to collect particulate in the range of 0,64 up to 19,4 {mu}m. Its advantage over commercially available cascade impactors is the selections of particulate in the respirable and inhalable fractions of aerosol. The experimental calibration of the ICN agreed with the theoretical calibration. The results obtained with the ICN were compared to the ones obtained with other selective air samplers, in 3 plants. The particle size distribution and the Th mass concentration were determined in those plants. The size distribution of particulate containing Nb. U Zr, Pb. Fe, Y and Sr, and the elemental mass concentration was determined. A group of workers in installations B and C were also monitored through bioassay analysis of Th excreted in urine and feces. Air and bioassay results have shown that the systemic incorporation of Th is not significant. (author) 116 refs., 37 figs., 31 tabs.

    Full Text Available Plague caused by Yersinia pestis, has persisted in Brazil in several natural foci spread throughout rural areas in the States of Ceara, Paraiba, Pernambuco, Piaui, Rio Grande do Norte, Alagoas, Bahia, Minas Gerais and Rio de Janeiro. Nationwide surveillance of plague in Brazil based on serological testing started in 1983. We now present an update report of the examinations carried out in our laboratory from 1983 to 1992. The passive hemagglutination test for antibodies against fraction 1A antigen of Y. pestis and the passive hemagglutination inhibition control were employed for testing a total of 220,769 sera. Samples analyzed included 2,856 sera from clinically diagnosed plague cases or suspects, 49,848 sera from rodents of 24 species and 2 species of small wild carnivores (marsupials, 122,890 sera from dogs, and 45,175 sera from cats. Specific antibodies were found in 92 (3.22% human sera; 143 (0.29% sera from rodents of 8 species and from the two species of marsupials, 1,105 (0.90% sera from dogs and 290 (0.64% sera from cats. The presence of significant levels of specific anti-F1A antibodies among rodents and wild or domestic carnivores (dogs and cats indicates that all the Brazilian plague foci remain active in spite of the absence of human cases in some of them.A peste, infecção pela Yersinia pestis, se mantém no Brasil, em vários focos naturais, disseminados na área rural, dos Estados do Ceará, Paraiba, Pernambuco, Piaui, Rio Grande do Norte, Alagoas, Bahia, Minas Gerais e Rio de Janeiro.

    Full Text Available This study aims to describe childhood tuberculosis incidence in Southeast Brazil in 1996. It is a descriptive study based on secondary records from the Tuberculosis Division of the São Paulo State Health Department. The study area includes 40 cities, has some 1,800,000 inhabitants, and is located between São Paulo and Rio de Janeiro, the largest cities in Brazil. The study included cases up to 15 years of age. Independent variables were: sex, age, type of case, clinical presentation, radiology, AFB microscopy, HIV antibody tests, and method of discovery. The incidence rate in this age bracket was 10.4/100,000. Pulmonary manifestations were the most common, and control of contacts was the most common method of case discovery. AFB microscopy was performed in 18.6% of the cases and HIV testing was done in 14.9%. Incidence in this study was higher than for the State of São Paulo as a whole. Poor socioeconomic level, deterioration of public health services, treatment dropout by adults and their persistence as sputum-positive carriers, and flaws in case reporting and follow-up could explain these results.O objetivo deste estudo é descrever a incidência de tuberculose na infância, no Sudeste do Brasil.

The aim was to determine the prevalence of anemia, as well as its association with growth retardation. Data were collected from May to July 2000, and determination of hemoglobin (HGB employed an STKS Coulter counter. Two cut-off points were used to classify anemia, both established by the World Health Organization: HGB < 11.5g/dl and HGB < 12.0g/dl. The indicators height/age (H/A, weight/age (W/A, and weight/height (W/H below -2.0 standard deviations from the NCHS reference were diagnosed as growth retardation. Prevalence of anemia was 9.9% when HGB < 11.5g/dl was used, and 25.4% when the cut-off point was HGB < 12.0g/dl. Growth retardation was detected in 6.2% of children according to H/A, 4.0% for W/A, and 3.0% for W/H. There was no statistically significant association between the variables in the study. These findings confirm results of previous surveys where prevalence of anemia was much higher than that of growth retardation. The severe consequences of anemia in this age group justify the implementation of broad public policies to overcome this nutritional deficiency.

    Concentration levels of 226 Ra and 222 Rn have been analysed in most of the mineral spring waters available in the Aguas da Prata region, which is located in the Pocos de Caldas plateau, one of the biggest weathered alkaline intrusions of the world. In this plateau can be found many health resorts[based on springs of thermal and mineral waters. The Aguas da Prata spring waters show a large variety of composition. It has been observed bicarbonates, carbonates and sulphates salts in these mineral waters. The 226 Ra was determined by gross alpha counting of a Ba(Ra)SO 4 precipitate. The measurement was carried out in a low background gas flow proportional counter. The 222 Rn concentrations were determined by liquid scintillation method. Water samples were randomly collected at 9 spring sites over a period of one year, in order to evaluate the seasonal variation of these radionuclides. Lower concentrations were found mostly in the rainy season (summer), which presents 80% of the annual rainfall of the region (1500 mm/year). Higher concentrations up to 2223 mBq/L for 226 Ra and 131 Bq/L for 222 Rn have been observed in waters with low level of soluble salts. Waters which present high levels of carbonate and sulphate salts showed maximum values of 316 mBq/L for 226 Ra and 30 Bq/L for 222 Rn. This behaviour is mainly due to the physicochemical properties of these radionuclides in water as well as to the lithologic structure of the aquifers. (authors). 6 refs., 2 figs., 1 tab

    presented a bird survey of Rio Cipó valley from May 1998 to November 2002. The region is within the premises of 'Parque Nacional da Serra do Cipó', one of the most important conservation units of southeastern Brazil. Bird census were carried out through transect, mist-net captures and recording bird vocalizations. Species richness was estimated by jackknife method. It was recorded 226 species, belonging to 43 families. This represents 27% of all 837 bird species recorded at the Cerrado (a Savannah-like biome region of central Brazil. A total of 2,249 bird individuals were captured with 4,486.82 net-hours. This represented 119 bird species of 23 families. Species richness was estimated at 239 ± 5 species. Six species are considered endemic to this biome: Augastes scutatus (Temminck, 1824 (Trochilidae, Hylocryptus rectirostris (Wied-NeuWied, 1821 (Furnariidae, Antilophia galeata (Lichtenstein, 1832 (Pipridae, Cyanocorax cristatellus (Temminck, 1823 (Corvidae, Charitospiza eucosma (Oberholser, 1905, Saltator atricollis (Vieillot, 1817, and Porphyrospiza caerulescens (Wied-Neuwied, 1830 (Emberizidae. Three species are considered near-threatened to extinction: Sarcoramphus papa (Linnaeus, 1758 (Cathartidae, Cypsnagra hirundinacea (Lesson, 1831, and Charitospiza eucosma (Emberizidae. The Rio Cipó valley holds a significant number of the Cerrado bird species. Some habitats within this biome are becoming rare in the Cerrado region such as gallery forests, and the temporary lagoons along the rivers. Even waterfalls are disappearing in other regions of Brazil. In this sense, the 'Parque Nacional da Serra do Cipó' is achieving one of its aims, which is biodiversity conservation.

Neste artigo analisa-se essa evolução, relacionando-a com o processo de lutas sociais que levou à criação do Sistema Único de Saúde (SUS e com as políticas nacionais, estaduais e municipais de saúde bucal. Trata-se de um estudo qualitativo do tipo exploratório. Os dados foram obtidos em documentos oficiais e fontes bibliográficas variadas e por meio de entrevistas semiestruturadas com prefeitos, secretários municipais de saúde, coordenadores de saúde bucal e cirurgiões dentistas que vivenciaram as diversas fases das políticas de saúde bucal no município. Identificam-se as características mais marcantes na organização das práticas assistenciais em saúde desenvolvidas na cidade, localizando-as no cenário estadual e nacional. Conclui-se que, não obstante a consolidação da inserção da saúde bucal no SUS e a experiência adquirida no Município com a gestão dessa modalidade assistencial, também em Diadema observam-se dificuldades para superar o modelo de atenção focado nos grupos populacionais tradicionalmente priorizados, com destaque para escolares, pré-escolares e bebês. Nesse sentido, Diadema compartilha com os demais municípios brasileiros o desafio de reestruturar a atenção básica em saúde bucal, superar o tradicional modelo da odontologia escolar e criar novas possibilidades, como a abordagem familiar, com a finalidade de assegurar a universalidade e a integralidade da atenção.Although oral health policy in the city of Diadema, São Paulo, Brazil, from 1972 to 2007, the subject of this article, has accompanied the process of transformation of the sector's practices

    Full Text Available INTRODUCTION: Brazil has been called a nation in nutrition transitional because of recent increases in the prevalence of obesity and related chronic diseases. With overweight conditions already prevalent among middle-income populations, there exists a need to identify factors that influence nutrition behavior within this group. OBJECTIVE: To address this subject, a research study was implemented among middle-class adolescents attending a large private secondary school in Manaus, Amazonas, Brazil. The study determined the availability and accessibility of snack foods as well as subjects’ attitudes and preferences towards, and the influence of family and friends on healthy (high-nutrient density snack choices. METHODS: The 4-stage process included: (a a nutrition expert focus group discussion that reported local nutrition problems in general and factors related to adolescent nutrition, (b an adolescent pilot survey (n=63 that solicited information about snacking preferences and habits as well as resources for nutrition information and snack money; (c a survey of various area food market sources to determine the availability and accessibility of high nutrient density snacks; and (d a follow-up adolescent survey (n=55 that measured snack food preferences and perceptions about their cost and availability. RESULTS: Results included the finding that, although affordable high nutrient density snacks were available, preferences for low nutrient density snacks prevailed. The adolescents were reportedly more likely to be influenced by and obtain nutrition information from family members than friends. CONCLUSION: From study results it is apparent that a focus on food availability will not automatically result in proper nutritional practices among adolescents. This fact and the parental influence detected are evidence of a need to involve adolescents and their parents in nutrition education campaigns to improve adolescent snack food choices.INTRODUÇÃO: O

    ções do Recôncavo Baiano, a aplicação do sistema de pré-aviso biológico para o controle químico da Sigatoka-amarela, deve utilizar o valor de Soma Bruta 1600 como indicador da época correta de realização das pulverizações. Nesta condição, houve uma redução de treze para oito aplicações anuais, ou seja, 40% menos defensivos aplicados, sem perda na produtividade.Yellow Sigatoka (Mycosphaerella musicola Leach is one of the most serious banana diseases in Brazil, it can cause yield losses higher than 50%. The main control method has been based on spraying fungicides. The use of a monitoring system able to indicate the appropriate moment for spraying fungicide, is a very important alternative to rationalize its uses. This work aimed to defining a Total Sum value for the biological forecasting system that allows to reduce the number of annual fungicide applications needed for Yellow Sigatoka control in Recôncavo Baiano Region. The work was carried out at Embrapa Cassava & Fruits, of the Brazilian Agricultural Research Corporation - EMBRAPA , located in the Municipality of Cruz das Almas, State of Bahia. Eight treatments were evaluated: six of them using pre-established Total Sum values of the biological forecasting system (1000; 1300; 1600; 1900; 2200 and 2500, the sistematic disease control by fungicide spraying every 21 days, and the control treatment without spraying. The treatments consisted of eight plots containing 48 plants each, of the cultivar Grand Naine. Every week, ten plants of each treatment were evaluated for rate of leaf emission and disease incidence in the leaves 2, 3 and 4, in order to determine the highest degree of lesion intensity. The weekly data were used to calculate the respective Total Sum values thus indicating the necessity or not of fungicide application (propiconazole, 3 mL, plus mineral oil, 1 L. At harvest, data on production and disease severity were taken. Only three of the evaluated treatments were statistically different

    Production of electrical energy by nuclear reactors is unnecessary in Brazil. This option, which was concrete by the beginning of the 1970`s, had its origins in the industrialized countries of the northern hemisphere. It signified a political ideological decision of an authoritarian and strategic nature, and not a technical scientific or ethical one. It began with the purchase of Angra 1 and was intensified in 1975, with the signing of the Brazilian-German Nuclear Agreement, establishing a double dependency: that of the nuclear reactors and that of combustion. The federal government was interested in the transference and command of technology, the production of electrical energy being secondary. Even through it was used as a justification for the country, the offer of electrical energy was already greater than the demand. In 1979, the Parallel Nuclear Program entered the scene. It was not subject to international inspections and was under exclusive control of the Armed Forces and the National Commission of Nuclear Energy, whose growing strength during the entire decade of the 1980`s is notorious. At the same time, the Brazilian Nuclear Program lost in the 1980`s the vitality that could be observed for the previous decade. It incurred accentuated technical errors and presented an extremely serious situation principally with regards to the emergency plan for the population of Angra dos Reis and neighboring cities and for the disposal of radioactive residues, which continue without a solution or definitive place. It is concluded that it is not possible to proceed with a energy policy that subsidizes electrical energy - the least expensive in the world - preponderantly to the industrial sector, for the private national and trans national initiative. In this situation there is no room for thermonuclear energy, onerous to the public coffers and dangerous to the population, to the natural environment and to the entire Planet.

    At first a university research centre, then a captive research centre of the state owned company in charge of establishing a nuclear industry in Brazil, then a research centre of CNEN (the Brazilian Nuclear Energy Authority), nearing its 50 th anniversary, CDTN has a rich experience. even keeping the project portfolio around a number of traditional nuclear energy areas such as nuclear reactors, materials, environment, process engineering, waste management, radiological protection, the institution experienced an evolution in the substance of the proposed projects. This evolution represents the different institutional insertions, but the major changes occurred at a time when, due to a lesser demand from the nuclear sector and other factors, the explicit idea of producing outputs for the benefit of society received a large acceptance from the employees. The challenges to the institution at this time are commented upon. Retirements, coupled to the lack of job openings, work together for the decrease in the staff number, one major challenge. Up to a certain point, private companies have been hired to fill some of the organisational needs, but it is felt that a limit to this policy is being reached. It is argued that, even in the absence of a strong demand from the energy generation sector, a number of opportunities are still available to a NRC in a developing country. Maturity of nuclear energy and applications of radiation tend to transfer the focus of the activities from the fundamentals of nuclear science and technology to quality related issues, a requirement of the modern times. quality systems cannot substitute for the in depth knowledge of the fundamentals.

    Full Text Available O estudo analisa a resposta brasileira em contraste com as metas estabelecidas para a prevenção do HIV/Aids pela UNGASS. Analisaram-se pesquisas nacionais, documentos e informações do Programa Nacional de DST/Aids e dos planos de ações e metas estaduais. O Brasil conta com vários programas de prevenção que atendem às metas da UNGASS propostas para 2005. Incluem o confronto do estigma e da discriminação, o estímulo ao teste anti-HIV, a distribuição de preservativos, a troca de seringas, a abordagem franca da sexualidade nas escolas, a prevenção entre trabalhadores do sexo e homossexuais e nos locais de trabalho, que resultaram no crescimento da testagem e do uso do preservativo masculino. Foram discutidos vários desafios: superar a descontinuidade das ações, especialmente junto a alguns grupos mais vulneráveis; capacitar equipes de prevenção; ampliar o monitoramento da qualidade e quantidade das ações de prevenção; superar as desigualdades regionais, de raça e de gênero. Concluiu-se que o direito à prevenção não é prioridade nas instâncias públicas de controle social ou nas agendas do movimento social, como tem sido o direito ao melhor tratamento dos portadores do HIV. Para ampliar a efetividade dessas ações, sugere-se compreendê-las e pactuá-las tendo como referência a promoção e garantia de direitos humanos, abrindo espaços para o debate ético-político no nível local e nacional.The study evaluates the Brazilian response to the targets established by UNGASS for the prevention of HIV/AIDS.

Forty nine patients from both genders, aged 14 to 70, with cutaneous ulcers for less than three months and a positive imprint for Leishmania spp. amastigotes were recruited into two groups. Group I (26 patients received a daily-single oral dose of 500 mg of azithromycin for 20 days and Group II (23 patients received a daily-single intramuscular dose of 20 mg/kg of meglumine antimony, also for 20 days. Azithromycin cured three of 24 (12.5% patients on days 60, 90 and 120 respectively whereas therapeutic failure was considered in 21 of 24 (87.5% cases. In group II, antimony cured eight of 19 (42.1% cases as follows: three on day 30, one each on day 60 and day 90, and three on day 120. Therapeutic failure occurred in 11 of 19 (57.9% individuals. The efficacy of antimony for leishmaniasis was better than azithromycin but analysis for the intention-to-treat response rate did not show statistical difference between them. Although azithromycin was better tolerated, it showed a very low efficacy to treat cutaneous leishmaniasis in Manaus.Com o objetivo de avaliar a eficácia da azitromicina no tratamento da leishmaniose cutânea, foi realizado ensaio comparativo, em Manaus.

Foram realizadas quatro campanhas no período de fev./2003 a mar./2004, em sete pontos de amostragem localizados ao longo do Rio Acaraú. Foram analisados 25 parâmetros físico-químicos e bacteriológicos. Pelo emprego da AF/ACP, identificou-se que o modelo de melhor ajuste para expressar a qualidade das águas na Bacia do Baixo Acaraú foi aquele composto por quatro fatores, explicando 82,1% da variância total. O primeiro fator representa a componente de sólidos em suspensão, expressando o processo de erosão e escoamento superficial. O segundo fator é definido por uma componente de nutrientes associados aos esgotos sanitários, às áreas agrícolas e a outras fontes de poluição difusa; o terceiro fator é indicativo da ação antrópica (componente orgânica, enquanto o quarto representa os sais solúveis que expressam o processo natural do intemperismo das rochas. Outro ponto observado é que a análise fatorial não resultou em grande redução no número de variáveis, uma vez que o melhor ajuste do modelo ocorreu com a inclusão de 18 das 25 variáveis analisadas.Multivariate statistical technique, factor analysis/principal component analysis (FA/PCA, was applied to identify the human activity effects and natural processes on surface water quality in Low Acaraú basin, Ceará, Brazil.

    Full Text Available Self-rated health has been used extensively in epidemiologic studies, not only due to its importance per se but also due to the validity established by its association with clinical conditions and with greater risk of subsequent morbidity and mortality. In this study, the socio-demographic determinants of good self-rated health are analyzed using data from the World Health Survey, adapted and carried out in Brazil in 2003. Logistic regression models were used, with age and sex as covariables, and educational level, a household assets index, and work-related indicators as measures of socioeconomic status. Besides the effects of sex and age, with consistently worst health perception among females and among the eldest, the results showed pronounced socioeconomic inequalities. After adjusting for age, among females the factors that contributed most to deterioration of health perception were incomplete education and material hardship; among males, besides material hardship, work related indicators (manual work, unemployment, work retirement or incapable to work were also important determining factors. Among individuals with long-term illness or disability, the socioeconomic gradient persisted, although of smaller magnitude.A auto-avaliação da saúde vem sendo amplamente utilizada nos estudos epidemiológicos, não só por ser importante por si, mas também pela sua validade, estabelecida por suas relações com as condições clínicas e com o maior risco de morbi-mortalidade subseqüente.

    Full Text Available The phytoplankton community was studied around two artificial reefs (shipwrecks Servemar-X and Servemar-I, located off the coast of Pernambuco, northeastern Brazil, aiming to identify and thus, better describe these environments. Water samples were collected with Nansen bottle at three depths (surface, mid-column and bottom for chlorophyll a analysis and salinity; temperature and water transparency were also measured. To collect phytoplankton samples, a diver using SCUBA equipment carried out phytoplankton hauls with a 20 µm net around the shipwrecks, about 1.5 m from the bottom for approximatly 3 minutes. Chlorophyll a concentrations at the bottom varied between 0.61 and 5.97 mg.m-3, with an average that indicates a mesotrophic environment. Temperature and salinity registered small seasonal variation, while water transparency showed a seasonal spatial pattern positively related to Chl-a rates. As regards the phytoplankton community, diatoms were the most representative group in the samples, followed by dinoflagellates, and among the species, the cyanobacteria Trichodesmium thiebautii Gomont ex Gomont prevailed quantitatively. The ecological importance of these ecosystems was confirmed by the high diversity and evenness indexes, with the influence of coastal waters playing an essential role in phytoplankton structure and diversity.A comunidade fitoplanctônica foi estudada nas adjacências de dois recifes artificiais (naufrágios Servemar-X e Servemar-I, na costa de Pernambuco, nordeste do Brasil, com o intuito de identificá-la e melhor caracterizar esses ambientes.

    Full Text Available AIMS: We evaluated the potential of aquatic macrophyte communities as bioindicators in six small shallow lakes. METHODS: The sampling was conducted monthly for one year, during which all macrophytes were surveyed, and the water temperature, dissolved oxygen, pH, conductivity, total alkalinity, chlorophyll-a, suspended matter, total nitrogen (Nt and total phosphorus (Pt were measured. RESULTS: In total, forty-three species were recorded, and there were significant differences in the species richness and limnological conditions among the lakes studied. A canonical correspondence analysis showed that the concentration of nutrients (Nt and Pt, chlorophyll-a, suspended matter, dissolved oxygen and pH were the most important predictors of the distribution of macrophytes. Some emergents were related to the high concentration of nutrients, chlorophyll-a, and suspended matter. Moreover, the most submersed species were associated with environments with low nutrient concentrations and the lowest values chlorophyll-a and suspended matter. In addition, some species submerged and floating were related to low values pH, alkalinity and dissolved oxygen. Limnological differences between lakes may be cited as the main causes of the observed heterogeneous distribution of macrophytes. CONCLUSIONS: These results indicate the importance of limnological characteristics of the different environments in the macrophyte community composition and the potential role of this community as a bioindicator in shallow lakes in southern Brazil.OBJETIVO: Foi avaliado o potencial bioindicador da comunidade de macrófitas aquáticas em seis pequenos lagos rasos.

    This work presents an application of Failure Mode Effect Analysis (FMEA) to the process of identification of environmental aspects and impacts as a part of implementation and maintenance of an Environmental Management System (EMS) in accordance with the NBR ISO 14001 standard. Also, it can contribute, as a complement, to the evaluation and improvement of safety of the installation focused. The study was applied to the Nuclear Fuel Center (CCN) of Nuclear and Energy Research Institute (IPEN), situated at the Campus of University of Sao Paulo, Brazil. The CCN facility has the objective of promoting scientific research and of producing nuclear fuel elements for the IEA-R1 Research Reactor. To identify the environmental aspects of the facility activities, products, and services, a systematic data collection was carried out by means of personal interviews, documents, reports and operation data records consulting. Furthermore, the processes and their interactions, failure modes, besides their causes and effects to the environment, were identified. As a result of a careful evaluation of these causes it was possible to identify and to classify the major potential environmental impacts, in order to set up and put in practice an Environmental Management System for the installation under study. The results have demonstrated the validity of the FMEA application to nuclear facility processes, identifying environmental aspects and impacts, whose controls are critical to achieve compliance with the environmental requirements of the Integrated Management System of IPEN. It was demonstrated that the methodology used in this work is a powerful management tool for resolving issues related to the conformity with applicable regulatory and legal requirements of the Brazilian Nuclear Energy Commission (CNEN) and the Brazilian Institute of Environment (IBAMA).

    The sediments are an important compartment used as a tool for assessment of aquatic ecosystems quality, for indicating the presence of contaminants released continuously into the environment as a result of human activities. Among chemical substances discharged to surface water, there are metals that in undesirable amounts, can be toxic to biota. Due to the importance of sediment and of shortage of data of water quality of the Araguaia-Tocantins river system, the present study conducted an assessment of environmentally available metals in sediment samples from water for public supply of the city of Palmas, in Tocantins, Brazil. The concentrations of As, Cd, Pb and Se were analyzed by Graphite Furnace Atomic Absorption Spectrometry (GFAAS), Ag, Al, B, Ba, Be, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Sb, Sc, Si, Ti, V and Zn were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICPOES) and Hg by Cold Vapor Atomic Absorption Spectrometry (CVAAS). Two partial solubilization processes were performed for a comparative study, one with HCl 0,1 M and agitation at room temperature, considered a milder method for metal extraction from anthropogenic origin, and another with HNO{sub 3} 8 M and microwave heating, considered as an alternative to more complex methods of total digestion, since it provides a good evaluation of the total concentration of the elements. The sediment quality evaluation was realized by comparing the concentration values of the elements As, Cd, Cr, Cu, Hg, Ni, Pb and Zn with the quality guidelines (TEL and PEL) adopted by Canadian Council of Minister of the Environment (CCME), to thereby contribute to the environmental quality of the water of the Araguaia-Tocantins river system.

    Full Text Available Uma versão condensada em português de um artigo de revisão sobre a periodontite da "cara inchada" dos bovinos, publicado em inglês, está apresentada com algumas informações adicionais. A doença foi responsável por grandes perdas de bovinos jovens, principalmente nas décadas de 1970 e l980 no Brazil Central. Em face da periodontite progressiva e a perdas de dentes, os animais não podem se alimentar convenientemente, tornam-se emaciados e podem morrer. A doença foi tida como uma deficiência ou desequilíbrio mineral. Mas as pesquisas de campo e de laboratório, realizadas durante 30 anos, mostraram que trata-se de doença infecciosa multifatorial a ser definida como Periodontite Epizoótica Bovina. Chegou-se à conclusão que os fatores principais para o seu desenvolvimento são: (1 a idade dos bovinos na fase de erupção dos dentes premolares e molares; (2 a presença de bactérias do grupo Bacteroides spp nos espaços subgengivais; e (3 a ingestão com a forragem de concentrações subinibitórias de antibióticos, sobretudo de estreptomicina, produzidos por actinomicetos cujo número é aumentado em solos virgens recém-cultivados na formação de pastagens após a derrubada da mata ou da vegetação de Cerrado; isto leva a um aumento da aderência dos bacteróides ao epitélio gengival e à destruição dos tecidos peridentários. Hoje em dia, a doença perdeu a sua importância e praticamente desapareceu, porque a microbiota do solo entrou novamente em equilíbrio e a abertura de grandes áreas virgens para a pecuária cessou. Porém, novos surtos podem ocorrer em áreas anteriormente positivas para a doença quando, na reforma de pastagens ou capineiras, houver um novo desequilíbrio da microbiota do solo. Outros antibióticos, como a espiramicina e virginiamicina, administrados por via oral ou adicionado a misturas minerais, podem controlar a periodontite.A condensed version in Portuguese of an extensive review on "cara

    Full Text Available Ischnocnema (Brachycephalidae includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853 is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is scarce. We studied the diet, the habitat use, reproduction and density of I. parva in an area of Atlantic Rainforest at the Concórdia mountain range, Rio de Janeiro. Individuals of I. parva were captured in April 2005 using different sampling methods: time constrained search (transects, plots of 5 x 5 m (25 m² on the litter, and pitfall traps with drift fences. We found 240 frogs; 35 females and 205 males. Females (mean SVL = 19.1 mm were significantly larger (F1,238 = 143.016, R² = 0.375, p < 0.001 than males (13.2 mm. The species preyed mainly on arthropods, with ants and isopods being the most important items, both showing high values of importance index (Ix = 50.0 and 26.7, respectively. Ischnocnema parva is a terrestrial species whose preferential microhabitat at the Serra da Concórdia was the litter of the forest floor (78.7%. The activity was predominantly crepuscular-nocturnal and the estimated density of I. parva was 24.9 ind/100 m². For the eight ovigerous females captured, the mean number of mature oocytes per female was 25 (range: 22-30 and the oocyte mean diameter was 1.11 mm (N = 40 oocytes. Oocyte number increased with female body size (R² = 0.504, F1,6 = 6.107, p < 0.05, N = 8, indicating that as females increase in size they produce larger clutches. Some ecological aspects such as diet and microhabitat use were similar to that observed for an insular population of I. parva, whereas reproductive traits differed. Thus, long term studies are necessary to understand the extent to which these differences are explained by environmental factors.

    Full Text Available O objetivo do estudo foi analisar o processo de monitoramento de indicadores centrais propostos pela UNGASS, em nível nacional, vis-à-vis aos indicadores do Programa Nacional de DST e Aids. Foram avaliados os dois conjuntos de indicadores propostos, respectivamente, em 2002 e 2005, para o monitoramento de progresso da Declaração de Compromisso da UNGASS. Foram analisadas a disponibilidade de informações e as limitações para o cálculo dos indicadores propostos no Brasil, incluindo discussão sobre a adequação dos indicadores propostos para o monitoramento da epidemia brasileira. Dos 13 indicadores quantitativos inicialmente propostos pela UNGASS, cinco não estão incluídos no sistema de monitoramento do Programa Pacional. Um deles não foi incluído por ser um indicador qualitativo. Dois dos indicadores foram considerados de pouca utilidade e dois não foram contemplados pela falta de dados disponíveis para o seu cálculo. Como o Brasil é caracterizado por ter uma epidemia concentrada, no segundo conjunto de indicadores propostos pela UNGASS, prioriza-se o acompanhamento da epidemia entre as populações sob maior risco. Destacou-se que o Programa Nacional centra seus esforços no desenvolvimento, adaptação e transferência de metodologias de amostragem em populações de difícil acesso. Tais ações são voltadas para a estimação do tamanho dos grupos vulneráveis, bem como para obter mais informações sobre seu comportamento, atitudes e práticas. Concluiu-se que, pela possibilidade de comparações internacionais dos avanços conseguidos, a proposição de indicadores supranacionais estimula os países a discutir e viabilizar sua construção. De maneira complementar, os sistemas nacionais de monitoramento devem ser focados na melhoria do programa, cobrindo áreas que permitam avaliar as ações de controle e intervenções específicas.The objective of this study was to analyze, on the national level, the process of

    Excavations (1 ) organized on a 12 m 2 surface have exhumed quaternary deposits under a 50 cm carbonate crust (layer I). These deposits were composed of angular broken stones compacted into breccia (layer II), yellowish sand (layer III) and reddish clayey sand (leyer IV), containing fossilized bones. These bones belong to extinct quaternary species, in particular Equidae. The uranium-thorium method was used to date several bone samples found in situ which gave these faunas an age of about 300,000 years. Several quartzite stone tools as well as fragments of quartzite and quartz pebbles were discovered among the fossil bones. In particular, the fragment of a pebble, broken by violent percussion and a chopper were found. The raw materials, quartzite and quartz, naturally absent from the cave could only have been brought there by prehistoric man. The Toca da Esperanca is, therefore, the most ancient site known on the American continent which contains evidence of early man. It provides evidence of human presence from the Middle Pleistocene period, about 300,000 years ago, well before the Calico sites in California (about 200,000 years) and the Santa Raimundo Nonato sites (about 30,000 years). In the light of these new discoveries, it is possible to surmise that Homo Erectus came from Asia very early during the Middle Pleistocene, passing the Behring Strait, during one of the big recessions in ocean levels which took place in the cold quaternary periods.

A score system was used to classify the performance of the implementation level in excellent (when 90-100% of activities were implemented; adequate (70-79%; inadequate (50-69%; and critical (<50%. The results show a significant weakness in the arterial hypertension care by the Family Health teams in Recife. The absence of specific programme coordination is related to the low performance observed. The implementation level was considered inadequate and some problems were identified due to the poor infrastructure, deficient inputs, low professional qualification for hypertension care and insipient use of information for planning the actions.

Este texto apresenta dados sobre a evolução da geração per capita de resíduos sólidos no Brasil e em outros países desenvolvidos, bem como os esforços e as dificuldades encontradas por estes últimos para a sua redução ou estabilização. São levantadas hipóteses sobre fatores sociais, econômicos e culturais que interferem no consumo e na consequente geração de resíduos sólidos, visando contribuir com o debate sobre o tema. Em uma primeira análise sobre a evolução da geração per capita dos resíduos sólidos no Brasil verifica-se uma maior propensão ao seu crescimento em função, principalmente, da melhoria da renda da população pobre e fatores culturais como a redução do tamanho das famílias e a entrada da mulher no mercado de trabalho.Reducing solid wastes generation is a priority for solid waste management in Brazil, according to the National Policy of Solid Waste. This paper presents data on trends in per capita solid wastes generation in Brazil, and in other developed countries, as well as the efforts and difficulties to reduce or stabilize that flow. In order to contribute to the debate on the subject, some hypotheses are raised about social, economic and cultural factors that affect consumption and the consequent generation of solid wastes. In a first analysis of the evolution of the per capita generation of solid wastes in Brazil, there is a greater propensity for growth due mainly to the improvement in the income of the poor and to cultural factors, such as reduction of the family size and inclusion of women in the labor market.

The press was a space for expression of a special breed of politics that was closely linked to the awakening of women to feminist ideas in the period after the armed struggle against the Brazilian dictatorship. The journals Brasil Mulher and Nós Mulheres portray, in their articles and editorials, the fight for amnesty, for day nurseries, for democratic freedoms - all symbols of opposition against the regime in the era of military dictatorship. In addition they report on specific matters, such as, domestic violence, women's working-conditions, reproductive rights, abortion and sexuality. From the point of view of the popular movement and the women's organizations, the alternative press of women is without any doubt an important source, and still under-explored, for understanding the period considered.

    2012-01-01

    This paper examines family planning in Brazil as biopolitics and explores how the democratization of the State and of reproductive health services after two decades of military dictatorship (1964-1984) has influenced health professionals' and family planning users' discourses and practices. Do health professionals envisage family planning as a 'right' or do they conceive it, following the old neo-Malthusian rationale, as a 'moral duty' of poor people, whose 'irrational' reproduction jeopardizes the family's and the nation's well being? And how do their patients conceptualize and embody family planning? To answer these questions, this paper draws on 13 months of multi-sited ethnographic research undertaken between 2003 and 2005 in two public family planning services in Salvador da Bahia, where participant observation was undertaken and unstructured interviews were conducted with 11 health professionals and 70 family planning users, mostly low income black women. The paper examines how different bio-political rationalities operate in these services and argues that the old neo-Malthusian rationale and the current, dominant discourse on reproductive rights, gender equality and citizenship coexist. The coalescence of different biopolitical rationalities leads to the double stigmatization of family planning users as 'victims' of social and gender inequalities and as 'irrational' patients, 'irresponsible' mothers and 'bad' citizens if they do not embody the neo-Malthusian and biomedical rationales shaping medical practice. However, these women do not behave as 'docile bodies': they tactically use medical and non-medical contraceptives not only to be good mothers and citizens, but also to enhance themselves and to attain their own goals.

As 52 espécies registradas neste estudo representam uma alta riqueza de peixes na lagoa Mangueira, sobretudo quando comparada a outras lagoas costeiras do RS. Padrões diferenciados de composição e abundância de espécies parecem refletir características distintas dos habitats litorâneos amostrados.This study presents the composition of species, the distribution and dominance patterns, and the structure of sizes of the assemblage of fish in distinct habitats (littoral, deeper and near shore limnetic zone of the Mangueira lake, in the southern Brazil. Samples were taken in the north, south and central regions of the lake from 2001 to 2007 using a multi-gear approach (gillnet, cast net, beach seine, dip net and bottom trawling. A total of 52 species were identified, 46 in the littoral zone, 33 in the near shore limnetic zone and 26 in the deep zone, distributed in 17 families, of the which, Characidae, Cichlidae, Loricariidae, and Atherinopsidae were the most diverse. The dominant species summed up 91.1 %, 92.9 % and 82.7 % of the all individuals caught in the littoral, deeper and limnetic zone, respectively. The littoral zone was comprised of small fishes, nearly 70 % between 25 and 50 TL mm. The dominance patterns showed that, in this zone, 19,5 % of the species were dominant, although four of those also prevailed in the other zones. In the deep zone, 7,6% of the captured species were dominant, with similar sizes to the littoral zone. For the other species, the sizes resemble to the near shore limnetic zone. The near shore limnetic zone was comprised of larger fishes, the major part between 150 and 200 TL mm, such as the great characins, the toothless characin and the silverside fishes. A larger difference was observed in the composition of species between the littoral and limnetic zones, with the species Jenynsia multidentata, Bryconamericus iheringii, Hyphessobrycon luetkenii and Gymnogeophagus gymnogenys dominating

Foram localizados dezessete artigos nas bases de dados Medline e Lilacs condizentes com os critérios de inclusão e exclusão definidos a priori. A maioria ateve-se aos componentes ensino/pesquisa, logística e farmacotécnica, a partir da observação de hospitais públicos localizados no Sudeste. Percebe-se a escassez de textos relacionados a atividades estruturais como gerenciamento e seleção. Estima-se que à formação acadêmica dos farmacêuticos atrele-se a percepção da manipulação como atividade preponderante nos serviços embora, atualmente, esta seja necessária apenas em um número restrito de hospitais. Soma-se a isto a baixa adequação das atividades realizadas a normas legais e padrões estabelecidos e a inexistência de revista brasileira dedicada ao tema e indexada pela BVS. Tendo em vista a maior freqüência de trabalhos oriundos do setor público, há, aparentemente, ou maior liberdade de atuação do farmacêutico neste setor ou menor produção científica, quantificada por publicações, no setor privado.This paper discusses the literature on hospital pharmacy services for in-patients in Brazil, seeking a broader view of its characteristics and priorities. Seventeen papers were located in the Medline and Lilacs databases that complied with the pre-defined inclusion/exclusion criteria. Most of them were related to teaching and research, logistics and compounding, based on observations in public hospitals in Southeast Brazil. Few studies focused on core activities such as management and selection. The academic syllabus through which pharmacy students are trained may underlie the perception that compounding is the preponderant aspect of hospital pharmacy services, although this is required in only a few institutions.

    This thesis considers uncertainty on the long term generation expansion planning in the Brazilian Electric System, under a Real Options Approach . First, Real Options Theory is used to demonstrate the importance of thermo power plants insertion in Brazil, through a flexibility valuation on hydrothermal system. This is the first objective of this thesis. In the second part a Real Options Model is proposed to support long term expansion studies, based in a levelized costs analysis. The adequacy of proposed models to real problem is illustrated by a case study of the Brazilian Power System. The results show the importance of the energetic matrix diversification on the Long Term Planning. In the expansion model proposed, results are in favor of higher participation of biomass, nuclear power and coal in Brazilian electricity generation matrix. (author)

    The determination of the hydraulic conductivity of a Red-Yellow Podzolic Soil was carried out during an experiment in a plot measuring 3.5 m x 3.5 m, at the Experimental Station of Itapirema, Goiania, in Pernambuco State, Brazil. The internal drainage method proposed by Hillel (1972) was used to obtain the hydraulic conductivity as a function of soil water content, K({theta}), in the three characteristic horizons of the soil. Three neutron probes were used for measuring the humidity, that was determined by a calibration curve. Three characteristic horizons of the Red-Yellow Podzolic Soil were investigated for hydraulic conductivity. The sandy A horizon, with large pores, has a high conductivity while the B1t horizon, with a massive structure and few visible pores, has a low infiltration rate. The hydraulic dynamics of the B2 horizon is more complex due to its heterogeneity. (author). 79 refs, 17 figs, 11 tabs.

Pedro Affonso Franco, o barão de Pedro Affonso. A introdução da vacina animal significou um avanço no controle da doença e impulsionou as discussões que redundaram no alinhamento de grupos médicos e políticos em torno de Oswaldo Cruz ou do barão de Pedro Affonso. Com a incorporação do Instituto Vacínico aos laboratórios de Manguinhos, terminou a polêmica que agitou os meios acadêmicos e políticos.Covering a period of roughly hundred years, the article looks at some of the more meaningful events during the period in which the small pox vaccine was institutionalized in Brazil. Discoveries and discussions then taking place in other countries are also examined, particularly as they influenced Brazil. The process is followed from introduction of the human vaccine to the arrival of the animal vaccine and creation of the Municipal Vaccine Institute - a private initiative by physician Pedro Affonso Franco, also known as the barão de Pedro Affonso. Adoption of the animal vaccine not only represented progress in controlling the disease but also spurred discussions that saw medical and political groups in Brazil taking sides with either Oswaldo Cruz or the barão de Pedro Affonso. The debate continued within the academic and political arenas until the Vaccine Institute was made part of the Manguinhos laboratories.

Nesse sentido, realizou-se estudo com o objetivo de avaliar o peso de fatores referentes às condições de vida da população, relacionando questões ambientais com a instalação e o impacto da cólera. MÉTODO: Através de uma regressão linear múltipla, pelo método "backward stepwise", com influência do investigador, foram correlacionados os indicadores socioeconômicos com as taxas de incidência por cólera observadas nos municípios do Estado de Pernambuco, no ano de 1992. RESULTADOS/CONCLUSÕES: O modelo ajustado indica que a proporção de domicílios que utilizam água não proveniente de uma rede geral é a variável que tem maior peso na flutuação positiva das taxas de incidência de cólera. As variáveis "proporção de domicílios não ligados à rede geral de esgotos" e "proporção de chefes de família com renda igual ou menor do que um salário-mínimo mensal" também se associam positivamente, com coeficientes de regressão estatisticamente significativos, às taxas de incidência de cólera. A proporção de domicílios sem nenhuma instalação sanitária, por outro lado, se associa negativamente às taxas de incidência de cólera, sugerindo que instalações sanitárias, sem existência de rede de esgoto, aumentam o risco de contaminação ambiental. Os resultados apontam que a maior prioridade em saneamento é a oferta de água de boa qualidade.INTRODUCTION: Factors associated with precarious living and environmental conditions are frequently cited as major obstacles for the control of cholera outbreaks and epidemics.

    Full Text Available O estudo da variação temporal de chuvas intensas é de grande importância na hidrologia, para a análise e previsão de eventos extremos, necessárias em projetos de controle de engenharia. Com esse objetivo, foram analisados dados de pluviogramas da cidade de Piracicaba, SP, do período de 1966 a 2000, para se determinar a distribuição temporal de chuvas intensas de 60 e de 120 min de duração. As chuvas de 60 min foram subdivididas em três intervalos iguais e sucessivos de 20 min cada um, enquanto as chuvas de 120 min foram subdivididas em quatro intervalos iguais e sucessivos de 30 min cada um. O modelo de distribuição da precipitação que predominou para as chuvas de 60 e 120 min, foi do tipo exponencial negativo, com 85,7 e 50,7% dos casos, respectivamente. Para as chuvas de 60 min, com altura pluviométrica média de 20,7 mm, a distribuição foi de 72,3, 21,4 e 6,2% do total precipitado, respectivamente, nos três intervalos sucessivos de 20 min. Para as chuvas de 120 min, com altura pluviométrica média de 33,3 mm, o resultado foi de 60,1, 25,2, 11,1 e 3,6%, respectivamente, nos quatro intervalos sucessivos de 30 min. O modelo de distribuição temporal dessas chuvas não foi modificado pelo total precipitado nem pela sua duração, nos intervalos em questão.Time distribution models of intense and short rains are very important in hydrology and for extreme predictions in engineering projects. With this purpose, rain data of Piracicaba, SP, Brazil, from 1966 to 2000 were analyzed to establish time distribution models of 60 and 120 min intense rains, during the rainy season from October through March. Time distribution models were assessed by three intervals of twenty minutes duration, for 60 min rains and by four intervals of thirty minutes duration for 120 min rains. The prevailing precipitation model for both, 60 and 120 min rains was a negative exponential distribution, in 85.7 and 50.7% of cases, respectively. For 60 min

    Full Text Available Foi feita revisão e análise, sob um ponto de vista antropológico, da literatura mais representativa sobre saúde e doença e práticas de cura no Brasil. Nessa literatura, em primeiro lugar, houve a preocupação de coletar documentos sobre as tradições regionais do mundo rural, expressando uma ampla variedade de pontos de vista. Em geral, "medicina popular" era vista como um conjunto de práticas e idéias rudes e imitativas, provenientes tanto da medicina erudita do passado como das tradições étnicas brasileiras. Em segundo lugar, as ciências sociais exerceram uma grande influência neste tipo de estudo. Depois dos anos 30 e, principalmente, dos anos 40 aos 70, um número importante de trabalhos tiveram lugar nesse campo de estudo, influenciados pelas posturas acadêmicas como, por exemplo, o funcionalismo, a teoria da aculturação, e as teorias do desenvolvimento. Durante os anos 70 o campo atingiu a sua maturidade com um grande número de pesquisas sob várias influências teóricas. As teorias estruturalistas e funcional-estruturalistas (que variam entre o formalismo abstrato e o substantivismo tiveram um peso mais consistente nessa década. Três importantes estudos recentes foram também analisados, e as principais tendências abertas nesse campo foram também discutidas, particularmente as tentativas marxistas de análise.An analysis was made of the most representative literature both on health and illness representations and on practices of cure in Brazil from an anthropological point of view. Firsttly, there was in this litterature the concern of collecting the folk traditions from the rural world, expressing a great variety of viewpoints.

    contextos econômico, político e social.Brazil's health system reform is one of the most successful examples of a non-centralized process of institutional building. Nevertheless, this was a limited process and those limits are related both with the nature of the institutions in charge of health services supply and with the population's demands, heavily committed with political democracy, considering that health is a citizenship right. This right placed the issues related to health services access to a central place in the Brazilian political debate; the poli ti cal and institutional reform of the State were guided to an empowerment of local government, now the main supplier of health services, since the 1988 Brazilian Constitution, a universal right to local health services. This thesis focuses on the relationship between demand and supply in health services, within the perspective of the daily life of the different social actors. The case of Volta Redonda - a historical birth land of the Brazilian steel metallurgy - is the basis of a local experience related to the health system reform. The building of the "Unified Health System (SUS" - the new health system created by 1988's BraziIian Constitution - in Volta Redonda was very successful, with the model named "Em Defesa da Vida" (In Defense of Life that reached the four main institutional principies of the national health reform, also adopting a very efficient family's health program, along with a homeopathy medical assistance program at the local level. The Volta Redonda success had been a limited one, because of non-biological factors. That means that social, political and economical variables were also very actively present on that scene.

    Full Text Available Knowledge on the factors influencing water erosion is fundamental for the choice of the best land use practices. Rainfall, expressed by rainfall erosivity, is one of the most important factors of water erosion. The objective of this study was to determine rainfall erosivity and the return period of rainfall in the Coastal Plains region, near Aracruz, a town in the state of Espírito Santo, Brazil, based on available data. Rainfall erosivity was calculated based on historic rainfall data, collected from January 1998 to July 2004 at 5 min intervals, by automatic weather stations of the Aracruz Cellulose S.A company. A linear regression with individual rainfall and erosivity data was fit to obtain an equation that allowed data extrapolation to calculate individual erosivity for a 30-year period. Based on this data the annual average rainfall erosivity in Aracruz was 8,536 MJ mm ha-1 h-1 yr-1. Of the total annual rainfall erosivity 85 % was observed in the most critical period October to March. Annual erosive rains accounted for 38 % of the events causing erosion, although the runoff volume represented 88 % of the total. The annual average rainfall erosivity return period was estimated to be 3.4 years.O conhecimento dos fatores que influenciam a erosão hídrica é de fundamental importância no planejamento do uso do solo. Dos fatores que alteram a erosão, a precipitação pluvial, expressa pela erosividade da chuva, é um dos mais importantes. Assim, o objetivo deste estudo foi determinar a erosividade e o tempo de retorno para a região dos Tabuleiros Costeiros, no município de Aracruz, ES. Para o cálculo da erosividade, foram utilizados dados pluviométricos de janeiro de 1998 a julho de 2004, obtidos em estações climatológicas automatizadas, localizadas em área experimental da Aracruz Celulose AS, que, para este estudo, geraram dados de 5 em 5 min.

    Full Text Available Neste artigo discutimos a ocorrência da filariose como um problema de saúde pública na cidade do Recife, capital do Estado de Pernambuco, que apresenta ainda hoje, em algumas áreas, níveis de prevalência preocupantes. Procura-se mostrar o papel da evolução urbana da cidade, caracterizada por um crescimento desordenado e pela formação de um número crescente de favelas, na criação de condições propícias para a transmissão desta parasitose. Identificamos categorias de análise, ligadas à organização social do espaço urbano, que devem ser incluídas como "mediadoras" em um modelo compreensivo da transmissão da filariose. Os aglomerados de habitações inadequadas, construídas em favelas superpovoadas, sem saneamento básico e sem sistema de drenagem de águas, propiciam as condições adequadas à proliferação dos mosquitos vetores da infecção e à manutenção da endemia.In this article the filariasis endemic is discussed as a public health problem in the city of Recife, capital of the state of Pernambuco, Brazil. Prevalence figures for this parasitic disease in some urban settings are cause for concern. The urban development process, characterized by disordered growth of cities and an increase in the number of slums, is pointed out as an important factor for the maintenance of conditions favouring disease transmission. Some analytical categories linked to urban social organization are identified and included in a comprehensive filariasis transmission model. Clusters of inadequate houses built in overcrowded slums without basic sanitation or a proper drainage system produce adequate conditions for proliferation of infection vectors and maintenance of the endemic.

    Brazil has now the seventh largest uranium reserve in the world. The Lagoa Real Uranium Province (PULR) is located in central-south region of Bahia State. Along a helical structure, north-south oriented, with approximately 33 km long, there are 34 known uranium mineralized areas. In its central-south portion is located anomaly 03 (AN03), named Lagoa da Rabicha, discovered and mapped by NUCLEBRAS (Brazilian Nuclear Enterprises), in the 80s. The Cachoeira Mine (AN13), located in northern PULR, is currently the only uranium mine in production in Brazil and even in South America. Nowadays it is observed a growth in energy demand in Brazil and also worldwide and studies and research applied to the petrogenetic uranium deposits are relevant both to be able to increase their potential for exploration and to assist in the possible future occurrences discovery. In recent years, fluid inclusions analysis (FI) have been widely used to study the genesis of uranium deposits in PULR and even thought there are still doubts about the uranium mineralization metallogenesis at Lagoa Real. Therefore, this work aimed to study the minerals and fluids associated with Lagoa da Rabicha albitites uraniferous and gneissic host rocks. In this way it was prepared an overview of the fluids found in this sector, establishing a comparison with several authors' studies in this and others Lagoa Real anomalies, trying to show the solutions evolution, at the same time that happened the uraninite precipitation. Petrography, electronic microprobe, laser ablation (LA-ICP-MS) and fluid inclusion studies were the applied methodologies. The fluids inclusions assemblages present in pyroxene, garnet and plagioclase, the main mineralogical constituents, were studied. The older fluid was found in aegirine-augite pyroxene and had aquo-saline composition (without carbonic phases) with Ca, Fe and Mg, 9-13 wt% NaCl salinities and homogenization temperatures between 220 and 290 deg C.

    Full Text Available Purpose: The research aims to evaluate the efficiency of banks that operated in the Brazilian market in 2013. To achieve this goal, efficient banks were identified according to the production approach. To detect and explain efficiency standards, additional analyses were carried out related to: 1. capital origin, 2. size, 3. business segment, and 4. risk rating. Originality/gap/relevance/implications: The Brazilian literature on bank efficiency features several studies linking the efficiency of banks to capital origin and size. However, the relationship between efficiency and business segment has been poorly explored and the relationship between efficiency and risk rating is scarce. In this sense, this research contributes to the literature by exploring the relationship between efficiency and business segment, as well as the relationship between efficiency and risk rating. Key methodological aspects: The research uses a quantitative approach and employs the Data Envelopment Analysis (DEA technique to calculate efficiency scores. The data were obtained from the Central Bank of Brazil (Bacen. Summary of key results: Federal public banks and large banks are, on average, more efficient. Banks operating in foreign exchange and retail, as well as banks with high credit ratings, also achieved high levels of efficiency. Key considerations/conclusions: Efficient banks proved to be more profitable, lent less money in proportion to their total assets, and received fewer complaints filed with the Central Bank of Brazil in 2013. Objetivo: A pesquisa tem como objetivo avaliar a eficiência de bancos que atuaram no mercado brasileiro no ano de 2013.

Longe de remeter a um processo homogêneo, a formação histórica desse grupo cobre um longo período temporal, envolvendo a interação de indivíduos provenientes de distin- tos grupos étnicos. A partir deste caso, objetiva-se fazer confluir a análise das estratégias acionadas pelos antecessores dessa comunidade para garantirem o acesso à terra em distintos contextos com dois conjuntos de discussões: aqueles suscitados pela historiografia brasileira acerca da escravidão e aqueles decorrentes da emergência de novos sujeitos de direito no Brasil, os remanescentes de quilombos.The text deals with the historical trajectory of the black rural community of Cambará, in Rio Grande do Sul, a state located in southern Brazil, which shares borders with Argentina and Uruguay and it is based upon written and oral sources Far from referring to a homogeneous process, the historical formation of this group covers a long period of time, involving the interaction of individuals from different ethnic groups. From this case, the objective is to conflate the analysis of strategies used by the predecessors of the community to ensure access to land in different contexts with two sets of discussions: those posed by the Brazilian historiography about slavery and those arising from the emergence of new subjects of rights in Brazil, the maroons - remanescents of quilombos.

    The problem of quality has been a constant issue in every organization.One is always seeking to produce more, to do it at a lower cost, and to do it with better quality. However, in this country, there is no radiographic film quality control system for radiographic services. The tittle that actually gets done is essentially ad hoc and superficial. The implications of this gap, along with some other shortcomings that exist in process as a whole (the state of the x-ray equipment, the adequate to use in order to obtain a radiography, the quality of the film, the processing of the film, the brightness and homogeneity of the viewing boxes, the ability of the radiologist), have a very negative impact on the quality of the medical image, and, as result, to the quality of the medical diagnosis and therapy. It frequently happens that many radiographs have to be repeated, which leads to an increase of the patient's exposure to radiation, as well as of the cost of the procedure for the patient. Low quality radiographs that are not repeated greatly increase the probability of a wrong diagnosis, and consequently, of inadequate therapeutical procedures, thus producing increased incidence of bad outcomes and higher costs. The paradigm proposed in order to establish a system for the measurement of the image's quality is Decision Theory. The problem of the assessment of the image is studied by proposing a Decision Theory approach. The review of the literature reveals a great concern with the quality of the image, along with an absence of an adequate paradigm and several essentially empirical procedures. Image parameters are developed in order to formalize the problem in terms of Decision Theory, and various aspects of image digitalisation are exposed. Finally, a solution is presented, including a protocol for quality control. (author)

Estimates of the association between race/color and access to pap-smear and breast exams were adjusted for income, education, economic class and age. Of the 2,030 women interviewed, 16.1% were black and 83.9%, white. Black women were significantly less likely to have had a pap-smear and/or breast exam than white women. Racial inequalities in access to cancer early detection exams persisted after controlling for age and other socioeconomic factors. Racial differentials in access to early detection (pap-smear exams for breast and cervical cancers might result from racial and socioeconomic inequalities experienced by black women in access to reproductive health care services and programs.O objetivo da pesquisa foi investigar o acesso de mulheres negras e brancas aos exames de detecção precoce de câncer de mama e colo de útero (citopatológico, em duas cidades no Sul do Brasil.

    This work has investigated the changes induced by {gamma}-radiation on impurity-related point defects in massive rose quartz from one deposit located at The Borborema Pegmatite Province (Northeast Region, in Brazil). Samples extracted from rose and colorless (milky) quartz blocks were irradiated with doses of {sup 60}Co, from 0.5 to 96 kGy. Point defects related to Al, Ge, Li and OH were measured by optical, infrared, and electron paramagnetic resonance spectroscopy, prior and after irradiation. The contents of Al, Li, Ge, Fe, Ti and other impurities were measured by inductively-coupled plasma mass spectrometry in quartz fragments exhibiting rose, pale-rose, and milky colorations. It was found that [AlO{sub 4}]{sup 0}, [AlO{sub 4}/H]{sup 0} and [GeO{sub 4}/Li]{sup 0} were generated by the dissociation of [AlO{sub 4}/Li]{sup 0} and [Li-OH] centers with doses as lower as 0.5 kGy. Above 8 kGy, the electron paramagnetic resonance signal related to [GeO{sub 4}/Li]{sup 0} decreases due to the intense mobility of Li species throughout the quartz lattice, giving rise to E'{sub 1} centers perturbed by Ge. The increase in [AlO{sub 4}]{sup 0} content with {gamma} doses and the consequent rise in the intensity of smoky color were similar for both rose and colorless quartz. Scanning electron microscopy carried out in insoluble residues obtained after chemical dissolution of each type of quartz revealed the presence of nanometric fibers only in rose specimens. These results suggested that the cause of rose color in massive quartz from Borborema Pegmatite Province is probably related to the presence of dumortierite inclusions. (author)

    The quality of Belford Roxo Industrial Plant effluent and water from Sarapui River were evaluated with Daphnia similis, Ceriodaphnia dubia and Danio rerio acute and chronic toxicity tests. In association with the ecotoxicological monitoring, the Toxicity Identification Evaluation procedure were performed and the identification of the toxic compounds was possible. The Chloride ion was identified as the major toxic compound in the effluent with additional effects of Metals, Ammonium and Sulfide. For the Sarapui River, the compounds of Phosphorus and Nitrogen were identified as the major toxic compounds with addictive effects of Metals, Ammonium and Sulfide. Although the environmental impact estimation based on the effluent toxicity suggests a minor impact on the water quality of Sarapui River, this was already sufficiently contaminated to make impracticable the establishment of an aquatic community. The constant discharge of untreated sludge promotes the eutrophication of this water body and makes impossible the equilibrium of this ecosystem. (author)

    Cutaneous leishmaniasis is a disease, caused by Leishmania parasites, that occurs frequently in tropical and sub-tropical regions of the world. Skin lesions that could results in disfiguring aspect characterize it. The treatment is based on few drugs as antimony salts or pentamidine that are toxic with increasing resistance by the parasite. Alternative forms of disease treatment are in constant search, including natural components as snake venoms. Previous studies demonstrate that some components of snake venoms have an inhibitory effect against those parasites, including Leishmania species. Although snake venoms presented high toxicity, several methods have been described to detoxify most or some of their toxic components, with favorable results by the use of gamma irradiation. In this report we tested several native and irradiated snake venoms for inhibitory effect against Leishmania (Leishmania) amazonensis parasite and LLCMK{sub 2} mammalian cells, with enzymatic tests and electrophoresis. There are significant activity in Acanthophis antarcticus, Agkistrodon bilineatus, Bothrops moojeni, Bothrops jararaca, Hoplocephalus stephensi, Naja melanoleuca, Naja mossambica, Pseudechis australis, Pseudechis colletti, Pseudechis guttatus and Pseudechis porphyriacus, venom being inactive Pseudonaja textilis, Notechis ater niger, Notechis scutatus. Oxyuranus microlepidotus and Oxyuranus scutellatus venoms. After 2 KGy of {sup 60}Co irradiation most venom loses significantly their activity. Venoms with antileishmanial activity presented L-amino acid oxidase (L-AO) activity and showed common protein with a molecular weight about 60kDa in SDS-PAGE. These results indicate that L-AO activity in those venoms are probably related with antileishmanial effect. (author)

Em termos gerais, o CEL sobre os peixes corrobora a literatura em ictiologia, trazendo informações originais em escala local. Pescadores de comunidades vizinhas e/ou praticantes de diferentes artes de pesca podem desenvolver denominações e um corpo deCEL diferenciado sobre os recursos pesqueiros de uma mesma área. Verificamos que a legislação que institui a moratória da pesca de Epinephelus itajara desconsidera as denominações locais da espécie, impossibilitando a sua interpretação pelos pescadores locais e gerando conflitos na aplicação da lei. As principais alterações ambientais registradas foram: diminuição da abundância dos recursos pesqueiros em geral (especialmente do Parambijú Rachycentron canadum, e os efeitos da interrupção antrópica do “Canal do Linguado” na hidrologia e sedimentologia da Baía Babitonga (assoreamento e aumento da turbidez da água.General aspects of the Local Ecological Knowledge (LEK of long-line and spear fishermen on seven fish species of the Serranidae family (habitat use, maximum size and popular names and on the main marine environmental changes were investigated in Babitonga Bay, Santa Catarina State, Brazil.

Neighbor fishermen communities can develop different local species nomenclature and different LEK for fishery resources at the same area. We have verified that the fishing ban legislation on Epinephelus itajara in Brazil does not consider local species denominations, turning impossible its interpretation by local

    Full Text Available Este artigo analisa os efeitos de políticas de descentralização na evolução das relações de poder entre presidentes, governadores e prefeitos no Brasil, após o fim do estado desenvolvimentista. Compara as conseqüências da descentralização pós-desenvolvimentista no Brasil com aquelas resultantes de processos similares na Argentina, na Colômbia e no México. Para explicar as diferenças observadas entre os países, o artigo desenvolve uma teoria seqüencial da descentralização, a qual é aplicada ao caso brasileiro.This article analyzes the effects of decentralization policies on the evolution of the balance of power among presidents, governors, and mayors in Brazil after the demise of the developmental state. It compares the consequences of post-developmentalist decentralization in Brazil to those that the similar processes had in Argentina, Colombia, and Mexico. To explain the differences observed among countries, the article advances a sequential theory of decentralization, which is then applied to the Brazilian case.

    Full Text Available O relacionamento entre os atores do sistema supletivo de assistência à saúde no Brasil é caracterizado por uma complexa trama de conflitos de interesse e de poder, que podem ser analisados à luz da teoria da agência. Ela emprega elementos da ciência econômica, principalmente das teorias do consumidor e do funcionamento de mercado, conjuntamente com idéias derivadas dos estudos organizacionais e comportamentais, faz uma divisão entre os agentes econômicos em principais e agentes. Analisando o mercado de assistência supletiva, pode-se constatar que ele possui inúmeros atores, que exercem ao mesmo tempo papéis de agentes e principais. É justamente dessa dualidade de papéis que surgem grande parte dos conflitos, e, através de diversos mecanismos de regulação, tenta-se reduzir os custos de agência derivados dos conflitos de interesse que são a causa principal dos problemas de agência dentro desse setor.The relationship between the actors of the supplementary healthcare system in Brazil is characterized by complex conflicts of interests and power struggles, which can be analyzed by the agency theory. This theory - combining elements of economic sciences, mainly consumer and market theories, with ideas derived from organizational and behavioral studies - divides the economic agents in principals and agents. The analysis of the supplementary healthcare market reveals its many actors play simultaneously the roles of agent and principal. This duality of roles is the root of most conflicts, originating several regulation mechanisms which try to reduce agency costs derived from conflicts of interests that are the main cause of this sector's agency issues.

Foram calculadas as taxas de cobertura potencial levando-se em conta a carga horária dos cirurgiões-dentistas do serviço e cobertura real, com base na produção ambulatorial odontológica. Encontrou-se uma adequada cobertura potencial de recursos humanos (1 cirurgião-dentista/1.618 habitantes e a taxa de cobertura real foi considerada abaixo do padrão proposto pelo Ministério da Saúde (0,39 procedimento/habitante/ano. A baixa cobertura real encontrada pode estar relacionada à baixa produtividade do serviço, cujas razões devem ser mais bem investigadas em estudos posteriores como problemas estruturais e a falta de um sistema de gestão do desempenho da qualidade da prática profissional com metas a serem cumpridas.This study seeks to evaluate dental care coverage in the State Military Police in Salvador, Bahia State, Brazil, from 2002 to 2004, estimating potential and real coverage rates. A single descriptive study was performed. Calculations were made of potential coverage rates considering hourly workloads of staff dentists and the real rates resulting from actual outpatient treatment. Potential human resources coverage was adequate (1 dentist per 1,618 policemen, while the real coverage rate was considered below the standard proposed by the Brazilian Ministry of Health (0.39 procedures per policeman per year. The low real coverage rate could be related to low productivity, the reasons for which should be investigated in greater depth in future studies, and might include organizational problems and lack of a management system to improve the quality of professional practice, with specifically defined targets.

And who is more suited intensively to consider the long-term perspectives than those engaged in the public health sector in whose competence, after all, such aspects, as "life certainty", "life expectancy" and "age at death" belong?Em 1985, as pessoas com mais de 60 anos de idade representavam 6,6% da população total do Brasil, enquanto na República Federativa da Alemanha esta proporção era, em 1984, de 20,3%; em 1950 havia chegado aos 14,5%. Esta proporção não será alcançada no Brasil, nem mesmo no ano 2000, pois se prevê que as pessoas acima de 60 anos comporão 8,8% da população total. Da mesma forma, no período 1982/84 a expectativa de vida ao nascer na República Federativa da Alemanha era de 70,8 anos, para homens, e de 77,5, para mulheres. No Brasil, para 1980/85, foi de 61,0 e 66,0, respectivamente. Com este pano de fundo entende-se porque o debate sobre o envelhecimento da sociedade com os seus múltiplos problemas - médicos, econômicos, individuais e sociais - tem demorado a assumir qualquer destaque no Brasil. Embora sejam importantes no Brasil estas considerações, elas constituem, no entanto, presentemente, apenas um lado da história. Para um europeu estudioso de demografia histórica com a vantagem de uma visão de 300 ou 400 anos, o outro lado da história é igualmente importante. O fato de a longevidade estar 10 anos mais baixa no Brasil não significa que ninguém nesse país viva até a idade avançada. Em 1981, pessoas de 65 anos ou mais representaram 34,4% do total de óbitos; ao mesmo tempo a mortalidade infantil representou 22,1% da mortalidade geral. Estas e as mortes "prematuras" entre jovens e adultos são responsáveis pela baixa cifra da vida média. Na Europa, por outro lado, as mortes "prematuras" já não desempenham importante papel

    Full Text Available Com base na categoria da superexploração da força de trabalho, formulada no âmbito da teoria marxista da dependência, apresentamos uma crítica à tese de que o Brasil estaria se tornando 'país de classe média' e sustentamos que um contingente substancial dentre o que vem sendo nomeado de 'nova classe média' consiste, na verdade, de trabalhadores - e suas famílias - vivendo em condições de superexploração. O texto encontra-se dividido em três seções. Na primeira, questionamos os pressupostos básicos da tese Brasil, país de classe média. Na segunda, expomos os fundamentos da categoria da superexploração e demonstramos seu incremento nas relações de produção do capitalismo brasileiro na década de 2000. Na terceira, demonstramos como o acesso da população trabalhadora ao consumo de bens duráveis no período recente, antes que a ascensão de uma suposta 'nova classe média', configura uma forma renovada de superexploração. Por fim, salientamos os nexos entre as condições de trabalho, saúde e direitos da classe trabalhadora no Brasil e as tendências do capitalismo mundial, questionando o falso dilema neoliberalismo e neodesenvolvimentismo no debate atual e colocando a real disjuntiva do ponto de vista da emancipação da classe trabalhadora em relação ao poder despótico do capital.Based on the workforce overexploitation category, formulated in the context of the Marxist Theory of Dependence, we critique the thesis that Brazil is becoming 'a middle class nation' and state that a substantial contingent of what has been named the 'new middle class' is, in fact, one of workers - and their families - living in overexploitation conditions. The article is divided into three sections. In the first, we questioned the basic assumptions of the 'Brazil, a middle class nation' thesis. In the second, we explain the fundamentals of the overexploitation category and show how it increased in Brazilian capitalism production

    Studies show that some regions of the Amazon region suffer mercury (Hg) impacts as a direct result of both natural and anthropogenic processes. Jau National Park (PNJ) is the only National Park in Brazil that protects an entire black water basin (Jau River), flood land and tropical reserve. These conditions favor Hg methylation in the aquatic biota. This in turn, exposes living on the river populations to Hg contamination as well as the adjacent regions. Preliminary studies of pre-school children diets from PNJ communities have shown that these diets have a worrisome high Hg content. The present study assessed total Hg content, micro nutrients (Ca, Fe, K, Na, Se and Zn) and macro nutrients (proteins, lipids, ash, energy, carbohydrate) in pre-school diets in the PNJ and surrounding communities. Furthermore, total and Me Hg levels were also determined in hair samples of these children as well as those living in several neighborhoods of the city of Manaus. Included in this determination were the fish most consumed by these populations. From these results it was possible to evaluate the nutritional content of the diets and the exposure of the children to Hg and Se Hg. Cold vapor atomic absorption spectrometry was used to quantify total and Me Hg. Micro nutrient determination was performed using neutron activation analysis technique (NAA) and Macro nutrient through AOAC methodologies (USA). All analytical methods were developed and validated for precision and accuracy by means of reference materials analyses with certified values for the determined elements. Furthermore, the uncertainty sources for Hg and Me Hg determination were assessed and the expanded uncertainties were calculated. Total Hg levels in diets and total and Me Hg levels for hair samples, were well above those values found in different localities of the Amazon region. This also holds true for those surrounding areas of the JNP. For many children Hg intake values passed the 5 mug Hg/body weigh/week (PTWI

MÉTODOS: a busca e seleção da literatura baseouse em artigos publicados em periódicos nacionais e internacionais, nas bases de dados eletrônicas Lilacs, SciELO e Medline. RESULTADOS: foram selecionados 14 estudos, sendo que 13 deles reportavam a prevalência de DPP e apenas um estudo de seguimento com limitada casuística (n=21 trazia estimativa da incidência do agravo (42,8%. A grande heterogeneidade em relação à população de estudo, método diagnóstico utilizado e período pós-parto focalizado dificultou a obtenção de uma estimativa agregada da prevalência de DPP no Brasil. Contudo, estudos conduzidos em unidades básicas de saúde, no âmbito da Estratégia de Saúde da Família ou em populações carentes apontaram uma prevalência entre 30 e 40% de DPP, enquanto pesquisas que incluíram amostras de base populacional e populações de unidades hospitalares terciárias revelaram uma prevalência de cerca de 20%. CONCLUSÕES: embora novos estudos sejam necessários para melhor caracterizar as peculiaridades que envolvem a magnitude da DPP no Brasil, as evidências disponíveis justificam uma atenção prioritária para os agravos à saúde mental materna no âmbito da saúde pública no país.OBJECTIVES: to carry out a systematic review of studies of the extent of post-partum depression (PPD in Brazil.

Situa sua argumentação a partir de alguns embates e algumas preocupações que vêm ocorrendo nesse campo do ensino nesta primeira década do milênio e, como exemplo, analisa um documento publicado pela Comissão de Educação e Cultura da Câmara dos Deputados, intitulado "Relatório final do grupo de trabalho; Alfabetização infantil: os novos caminhos", (Brasília, 2003.

No contexto da regulamentação da Emenda Constitucional 29, da renovação da CMPF e da DRU, e de uma próxima reforma tributária, são tratados aspectos do sistema tributário, das contribuições sociais, dos subsídios, incentivos e renúncia de arrecadação. Considera também aspectos político-institucionais das relações intergovernamentais e das relações entre o setor público e o setor privado, presentes ao financiamento da Saúde. O trabalho torna evidente a existência de espaço para ampliar o patamar de financiamento do SUS, de modo a superar os vazios sanitários, bem como as desigualdades de oferta de serviços no território. Sugere também a revisão das relações financeiras intergovernamentais e entre o setor público e o setor privado. Finalmente, apresenta aspectos virtuosos do gasto público e dos instrumentos de financiamento do setor para o desenvolvimento econômico e tecnológico do Brasil.This paper addresses the dilemma underlying Healthcare financing, caught between the long-term view proposed by the Social Security segment in 1988 and the short-term view imposed by a series of fiscal adjustments, hampering the expansion of healthcare resources in Brazil.

    The regulatory bodies request risks evaluations for nuclear and radioactive licensing purposes. In Brazil those evaluations are contained by the safety analysis reports requested by the Brazilian Nuclear Energy Commission (CNEN), and risk analysis studies requested by the environment organisms. A risk evaluation includes the identification of the risks and the accident sequence which can occur, and the estimation of the frequency and his undesirable effects on the industrial installations, the public, and the environment. The identification and the risk analysis are particularly important for the implementation of a health, environment and safety integrated management according to the regulation instruments ISO 14001, BS 8800 and OHSAS 18001. The utilization of the risk identification techniques and the risk analysis is performed at the non nuclear industry, in a non standard form by the various sectors of an enterprise, diminishing the effectiveness of the recommended actions based on risk indexes. However, for the nuclear licensing, the CNEN request through their regulatory instruments and standard formats, that the risks, the failure mechanisms and detection be identified, which can allow the preventive and mitigate actions. This paper proposes the utilization of the FMEA (Failure Mode and Effects Analysis) technique in the licensing process. It was implemented a software through the Excel program, using the Visual Basic for Applications program which allows the automation and the standardization of FMEA studies as well

Foram calculados os parâmetros fitossociológicos das espécies e das famílias botânicas para toda a área amostral e para cada um dos três setores da floresta. Foram obtidas medidas de dissimilaridade florística e estrutural entre os três setores amostrais e medidas de dissimilaridade florística entre a floresta do presente estudo e cinco outras florestas riparias do Distrito Federal e dos estados de São Paulo e Mato Grosso. As seis florestas apresentaram entre si índices muito altos de dissimilaridade florística, embora algumas delas apresentassem espécies em comum entre as mais abundantes. Os três setores amostrais mostraram igualmente uma considerável dessemelhança florística e estrutural entre si. O clima, os solos e a geomcrfologia das bacias hidrográficas são evocados como responsáveis pelas diferenças interregionais entre as florestas riparias. Já as dessemelhanças intrarregionais podem ser atribuídas à fertilidade dos solos e, sobretudo, ao regime de água nos solos e nos próprios rios, os quais, por sua vez, variam com a topografia local. Os padrões de distribuição espacial marcadamente diferentes que podem ser observados para várias espécies de árvores podem ser atribuídos à elevada heterogeneidade ambiental, peculiar às florestas de galeria.The gallery forest which occurs along one of the branches of the Córrego da Paciência, southern Mato Grosso, Brazil (15º 21'S, 55º 49'W, was surveyed by 67 plots of 30m² each (0.201 ha. Individuals > 9cm in circumference at ground level were recorded. Three sites of the forest were sampled: Nascentes, Vereda and Cachoeira

    Full Text Available As mudanças no ambiente institucionais e seus efeitos sobre o desempenho recente da produção de milho e soja no Brasil e Argentina são os objetivos deste artigo, que tem como referencial teórico a Nova Economia das Instituições. Importantes diferenças marcam o desempenho da produção de grão nestes países, apesar do Brasil e Argentina terem seguido o mesmo modelo de desenvolvimento baseado no processo de substituição de importação e economia fechada. Observa-se também que além das condições edáfo-climáticas que trazem uma vantagem inicial para a produção de grãos na Argentina, de uma forma geral, este país, em função da sua menor população e menor absorção interna de produtos, sempre teve uma maior inserção no mercado internacional.This paper examines the role of the institutions that affected Brazilian and Argentinean grain agroindustrial systems in this decade, using the New Institutional Economics as theoretical reference. Important differences mark the performance of the production of grains in these countries, despite Brazil and Argentina having followed the same model of development based on the process of import substitution and a closed economy. In addition to the edapho-climatic factor which brings initial advantages to the production of grains in Argentina, in general, this country has always had greater insertion in the international market due to its smaller population. The changes in the institutional environment and its effects on the recent performance of soybean and corn production in Brazil and Argentina are the objective of this work.

    Full Text Available A mangabeira (Hancornia speciosa Gomes é uma espécie cujas regiões de ocorrência natural vêm sofrendo grande pressão antrópica, a qual está provocando erosão genética em muitas populações nativas, principalmente da região Nordeste. Em virtude da existência de poucas coleções de mangabeira conservadas ex situ, evidencia-se a importância do desenvolvimento de um método alternativo e complementar para a conservação de germoplasma dessa espécie. A utilização de técnicas de cultura de tecidos de plantas para a conservação de recursos genéticos apresenta diversas vantagens sobre a conservação de germoplasma no campo, destacando-se a economia de recursos financeiros para a manutenção das coleções, redução de riscos fitossanitários e intempéries climáticas. Por esse motivo, o presente trabalho teve como objetivo avaliar a eficiência de regulador osmótico (manitol e inibidor de crescimento (ácido abscísico na conservação in vitro de microestacas de mangabeira por crescimento lento. As culturas foram mantidas em meio MS com 3% de sacarose e 0,6% de agar. Os experimentos foram conduzidos em delineamento inteiramente casualizado, em sala de crescimento com temperatura variando de 26±2°C, umidade relativa do ar média em torno de 70% e fotoperíodo de 12 horas de luz branca fria (52µmol m-2 s-1 de irradiância. Foram avaliadas cinco concentrações de manitol (0, 10, 15 e 20g L-1. Na presença de manitol, o comprimento da parte aérea apresentou valores numéricos inferiores à testemunha, mas, aos 90 dias de cultivo in vitro, foi observado efeito deletério do manitol nas microestacas. Em relação ao ácido abscísico, foram testadas cinco concentrações (0; 0,5; 1; 2 e 4mg L-1 em interação com dois tipos de vedação de frascos (tampa plástica rosqueada e papel alumínio e dois tipos de explantes (microestacas apicais e basais. O ácido abscísico (0,5mg L 1 apresentou melhores resultados para a conserva

    Full Text Available Analisa o diálogo do eugenista Renato Kehl com um grupo de psiquiatras brasileiros que, no início da década de 1930, aproximaram-se da chamada eugenia negativa. Entusiasmados com as pesquisas e a aplicação de medidas eugênicas em países como os EUA e a Alemanha, autores como Ernani Lopes, Ignácio da Cunha Lopes, Alberto Farani e Antonio Carlos Pacheco e Silva elegeram a religião católica como empecilho para que o Brasil pudesse seguir caminho semelhante, especialmente quanto à resistência à implantação da esterilização dos ditos 'degenerados' que passara a vigorar na Alemanha em 1934. O artigo mapeia as diferentes estratégias propostas pelos autores para dialogar com a Igreja católica.The article analyzes the dialogue between eugenicist Renato Kehl and a group of Brazilian psychiatrists who turned their interest to so-called negative eugenics in the early 1930s. Enthused about research into eugenics and the application of eugenic methods in countries such as the United States and Germany, authors like Ernani Lopes, Ignácio da Cunha Lopes, Alberto Farani, and Antonio Carlos Pacheco e Silva blamed Catholicism for impeding Brazil from moving in a similar direction, especially the church's resistance to the sterilization of 'degenerates', which entered into effect in Germany in 1934. The article charts the various strategies these authors proposed for engaging in dialogue with the Catholic Church.

    Full Text Available Objetiva-se, aqui, apresentar os aspectos conceituais da regulação da prestação dos serviços de água e esgoto no Brasil e analisar de forma comparativa essa regulação com a de outros setores da infraestrutura. O estudo parte do pressuposto da regulação como intervenção do Estado voltada para a eficiência e a equidade, e apresenta os fundamentos teóricos que justificam essa regulação de forma contextualizada às características do setor de água e esgoto. Mediante análise comparativa com outros setores de infraestrutura de redes, concluí-se que, em função das características físicas, econômicas e institucionais do setor de água e esgoto, será bastante complexo o estabelecimento efetivo dessa atividade conforme os princípios da lei nº 11.445/2007.The objective of this paper is to present the conceptual aspects of the regulation of water and sewage services in Brazil and to perform a comparative analysis of this regulation to the other sectors of the infrastructure. This study is based on the assumption of regulation as an intervention of the State turned to the efficiency and fairness, and presents the theoretical foundations to justify this regulation in the context of the characteristics of water and sewage sector. By comparison with other sectors of infrastructure networks, it has been concluded that depending on the physical, economic and institutional characteristics of water and sewage sector, this activity is quite complex to be effectively established according to the principles of law 11.445/2007.

    Full Text Available Esse artigo tem como objetivo avaliar o desempenho logístico de quatro elos da cadeia brasileira de suprimentos de refrigerantes (fornecedores de embalagem para refrigerantes, indústria de refrigerantes, atacado e supermercado, adotando como metodologia o survey eletrônico. As repostas foram analisadas utilizando-se os testes estatísticos Mann-Whitney e Kruskal-Wallis, além de uma análise descritiva dos dados e da realização dos testes de hipótese. As empresas avaliaram o desempenho logístico da cadeia, por meio de indicadores da logística interna e externa, e identificaram a percentagem de uso desses indicadores. A taxa média de respostas foi de 40%. A pesquisa mostrou que os elos da cadeia de refrigerantes utilizam mais os indicadores de desempenho, que avaliam a logística interna, do que os que avaliam a logística externa.An evaluation was made of the logistics performance of four links in Brazil's soft drink supply chain (soft drink packaging suppliers, soft drink industry, wholesalers and supermarkets, based on an electronic survey of 54 companies, from which a 40% response rate was obtained. The answers were analyzed based on the supply chain management theory, using the Mann-Whitney and Kruskal-Wallis statistical tests and a descriptive analysis of the data. The surveyed companies evaluated the logistic performance of the chain based on indicators selected from a literature review, and identified the percentage of use of these indicators. It was found that the links in the soft drink chain preferentially use internal logistics performance indicators more than external logistics indicators.

    Full Text Available O trabalho apresenta pesquisa etnográfica desenvolvida com crianças moradoras de um acampamento do Movimento dos Sem Terra, em Minas Gerais. Pela observação participante do cotidiano infantil e por meio de entrevistas com crianças, buscou-se apreender os significados da vivência da infância no interior de um movimento social organizado. No escopo deste artigo, no diálogo com os refereciais teórico-metodológicos da sociologia da infância, foram analisadas três das entrevistas realizadas, de forma a destacar a singularidade dos processos socializatórios vividos por tais sujeitos, definidos por duas categorias identitárias: geração e inserção em movimentos sociais. Verifica-se que as crianças, em sua ação coletiva voltada para a atividade do brincar, buscavam interpretar sua experiência coletiva, lançando mão de elementos da cultura infantil, de forma a elaborar o vivido. Ao mesmo tempo, buscavam estabelecer relações com outros universos sociais, tais como a escola, de maneira a construir novos espaços de sociabilidade.This papper describes an etnographical research realized with a group of childs from the Movimento dos Sem Terra of Minas Gerais/Brazil. Using metodologies strategies like participative observation and interviews, we focused the signification of childhood experience inside an organized social movement. According to that, in dialogue with the teorical references of Childhood Sociology, the research analises their identity construction process, considering two central categories: generation and insertion in social movements. The children, in coletive action centered on playing, uses it to i
