    The Ore Treatment Unit (OTU) is a uranium mining and milling plant, situated at Caldas city, Minas Gerais, Brazil that was disabled in the mid 90's. This unit releases controlled effluents to three rivers: Ribeirao das Antas (at point 014, influenced by the waste pile), Ribeirao Soberbo (point 025, influenced by the waste pond) and Corrego da Consulta (at point 076, influenced by the open pit mine). Water samples collected at these points were analyzed for U{sub nat}, {sup 226}Ra, {sup 210}Pb, {sup 232}Th and {sup 228}Ra content in the particulate and soluble fractions, and the behavior of radionuclide releases and their fractions was investigated. U{sub nat} and {sup 228}Ra showed identical behaviors at these three points. U{sub nat} at point 014 (waste pile) behaved different from described in recent literature data. The isotopes of Ra should exhibit the same behavior at each point, but this was not observed at point 025 (waste pond). {sup 232}Th release showed equal activity concentration near the waste pile (point 014) and near the waste pond (point 025), whilst near the open pit mine (point 076) the soluble fraction showed a concentration of activity greater than the particulate fraction. Finally, {sup 210}Pb showed a different behavior at each point. Due to the great differences in behaviors of each radionuclide, it was not possible to establish a temporal pattern of release which requires assessment over a longer period of time. (author)

  3. How Stakeholder Engagement is Evolving at the Caldas Uranium Mining Site in Minas Gerais, Brazil - 13223

    International Nuclear Information System (INIS)

    The Caldas site is located in the Federal State of Minas Gerais in Brazil about 25 km from the city of Pocos de Caldas. While the city itself has 150,000 inhabitants there is a total population of around 0.5 million people living in an area that could potentially be influenced by the site. Uranium ore was mined and milled here between the years of 1982 and 1995, with ore extraction taking place from an open pit. Of the material removed, aside from that extracted for uranium, some was used on-site for road construction and building embankments while the remainder was disposed of onto two major rock piles. There are a number of potential historical and current environmental impacts to groundwater as a consequence of discharges into streams which then flow off site. The site is now undergoing a phase of decommissioning which includes the formulation and substantiation of a site remediation strategy. As part of a wider International Atomic Energy Agency (IAEA) Technical Cooperation Project aimed at providing practical guidance for implementing a decommissioning and remediation plan at the site, WSP E and E were invited to lead a mission in order to provide advice on the importance and merits of stakeholder engagement and how to ultimately build an engagement program. In November 2011, WSP E and E met with personnel from the site operators, the Brazilian regulatory bodies and representatives from the local stakeholder community and explained the principles of stakeholder engagement and how the process had internationally evolved principally from a decide-announce-defend approach to a more formal two way mechanism of engagement. Historically there had been insufficient liaison between the site operator, the nuclear regulator and the environmental regulator. All parties had recognized that greater interaction was necessary. There had also been very little engagement with local stakeholders about the various activities on the site and the potential implications of these

    Currently, the quality of the water consumed by the population, and also the water used for both leisure and therapeutic bathing, are known. In the city of Poços de Caldas, Minas Gerais, Brazil, the population has two sources of sulfurous thermal water, with free access for various purposes, including drinking. Since 1882, the system has retained the same structural characteristics, and at this time, there appears to be a risk of anthropogenic contamination due to population increase near the springs. The aim of this study was to evaluate the water quality of the sulfurous hot springs distributed in Pedro Botelho fountain, located in Thermas Antônio Carlos, and Monkey fountain, located in Mario Mourao bathhouse, for microbiological and bacteriological components, physical and chemical composition, and radionuclides for a period of 12 months and to compare their quality with Brazilian water quality laws. The results showed that all the values are within the prescribed water quality parameters, except fluoride and sodium, whose levels are above those permitted by law. Excess fluoride in consumed water can cause dental fluorosis and skeletal fluorosis. As for sodium, which exceeded the permissible limits by 20 to 25 %, it can be detrimental to hypertensive individuals. An important fact to consider is that water from sulfurous hot springs cannot be consumed without medical supervision because its chemical characteristics may cause damage to health, and it should only be used as medicinal mineral water.

  5. Impact of 210PB from Osamu Utsumi mine on sediment of rivers in Caldas Region, Minas Gerais

    International Nuclear Information System (INIS)

    The Osamu Utsumi Mine of the Industrias Nucleares do Brasil (INB) is located in Caldas region, Minas Gerais, Brazil. It is a uranium mining and is in process of shutdown, decommissioning stage. CDTN/CNEN (Nuclear Technology Development Center, sponsored by Brazilian Commission for Nuclear Energy) is participating in this decommission step. One contribution will be the characterization of the environmental liability, determining the impact on the environment caused by mining activities. Several radionuclides are being analysed in diversified matrixes, however, this paper is about determination of 210Pb in sediment of rivers. One reason to analyse 210Pb is due to its long half-life (22.3 years) that may point out the carrier of 222Rn, 226Ra, 228Ra, even U, in the region. Besides, it may be used to date sediment. The methodology applied to determine the 210Pb activity in sediment was gamma spectrometry that was established at CDTN during the development of this study. The results confirmed the impact of the uranium mining on the environment. (author)

    Full Text Available The generation and disposal of the garbage has causing a series of impacts and risk for the human health at Brazil. The main goal of this research was carry out an environmental diagnosis at areas of arrangement of the garbage at the county of Poços de Caldas, in the state of Minas Gerais, Brazil. The methodology was comprised of visits and photographic survey of the site and chemical analysis of soil (pH, P, S, K, Ca, Mg, Al, B, Cu, Fe, Mn and Zn in 2003 and 2005. The photographic survey showed that the area is characterized like a dump, up to the year of 2005, and the chemical analysis showed degradation at the plot of arrangement of the garbage. The concentration of Mn reached 45.7 mg dm-3. In spite of the fulfilled improvements, the area keeps on presenting risk of contamination of the water resources.Keywords: garbage, soil pollution, landfill leachate.

  7. Risk management in environmental pollution: a case study of the uranium mining and milling facilities at Pocos de Caldas, Minas Gerais, Brazil

    International Nuclear Information System (INIS)

    Environmental risk management concept was adapted to uranium mining and milling facilities at Pocos de Caldas, Minas Gerais, Brazil. Environmental radionuclide and metal concentration in surface waters, efficiency of the effluent treatment were evaluate. The data shows that the effluent treatment was effective to reduce pollutant releases in the environment but the benefit in the dose reduction may be questioned. In addition it's stressed the necessity of a metal exposure assessment due to vegetables consumption that has never been developed in that region. (B.C.A.). 07 refs, 02 figs, 02 tabs

  8. Radium-226 and head-210 in agriculture products produced on the environs of the uranium mine and mill at the Pocos de Caldas plateau in Minas Gerais

    International Nuclear Information System (INIS)

    Radium-226 and Lead-210 in agriculture products produced on the environs of the uranium mine and mill at the Pocos de Caldas Plateau in Minas Gerais. As a complement to the pre-operational environmental monitoring program of the Brazilian first uranium mine and mill, a survey of 226Ra and 210Pb in agriculture products, and in the corresponding soils, were carried out in the Pocos de Caldas Plateu. The survey intended to determine site specific transfer factors, in order to better estimate radiation doses on the population, resulting from the plant operation. In local soils, 226Ra and 210Pb have similar concentrations. The average contents are comparable to the values found in areas of normal radioactivity, but the maximum values are higher by one order of magnitude. In the vegetables analyzed (beans, carrot, corn and potato), 226Ra concentrations are slightly higher than those of 210Pb, and the maximum values are also one order of magnitude greater than in normal regions. For both radionuclides, the average soil-to-plant transfer factors are of the order of 10-3 and 10-2 when related to total and to exchangeable content soil, respectively. These results led to the conclusion that 226Ra and 210Pb have similar importance, concerning the population exposure via the foodstuff ingestion pathway. Therefore, it was recommended to carry on routine monitoring program for both radionuclides in the main agriculture crops. However, the naturally elevated radionuclide concentrations, in some local vegetables, will decrease the sensivity for detecting for detecting small increments resulting from the plant operation.

  9. Petrography, structure and geochemistry of nepheline syenites from the Pocos de Caldas alkaline massif, states of Minas Gerais and Sao Paulo, Brazil

    International Nuclear Information System (INIS)

    The subcircular Mid-Cretaceous Pocos de Caldas alkaline massif, states of Minas Gerais and Sao Paulo, southern Brazil, covers over 800 Km2, and has as its main rock types phonolites and nepheline syenites, with subordinate amounts of pyroclastic rocks. Nepheline syenites consist mainly of K-feldspar, nepheline and pyroxene, varying both in texture and 'rare-metal silicates' content. A useful petrographic division is that which classifies the rocks into agpaitic and non-agpaitic (miaskitic or intermediate) types. The latter varieties, characterized by the absence of rare-metal silicates, are predominant by far; agpaitic types are easily recognized by the presence of eudialyte and other rare-metal silicates. Both petrographic and, as far as possible, structural descriptions as well are given for most of the mapped nepheline syenite bodies; many bodies show subhorizontal or moderately-dipping contacts with their country rocks. Chemically, these rocks show, on the whole, high alkaline contents (12-15%) and commonly very high K2O abundances. Chemical as well as additional isotopic and geochronological (Rb/Sr) data suggest that the asthenosphere is the source of parental magmas for the Pocos de Caldas nepheline syenites. The same arguments are used to reject, as unlikely, the magmatic activity interval (over 30 m.y.) given by previously published K/Ar ages. Simple structural models of the crust lithosphre in the Parana Basin area, coupled with the westward plate movement, suggest that irregularities at the asthenosphere-lithosphere decoupling surface are probable sites for melting of asthenospheric (and lithospheric) rocks induced by pressure relief.

  10. Subsidies to the decommissioning of the first uranium mining and processing plant in Brazil - the case of the mineral industrial complex in Pocos de Caldas, Minas Gerais State

    International Nuclear Information System (INIS)

    The closure of an uranium mining and milling facility has the potential to cause risks (radiological and non-radiological) to the human health and to the environment as a whole; these risks may be incurred in the short as well in the long terms. The present work took the mining and milling facility of Pocos de Caldas, Minas Gerais - as a study case. The following aspects were covered by the work: analysis of the impacts associated to the facility operation; assessment of the geological processes involved in the mobilization of radioactive and non-radioactive pollutants from the main sources of these pollutants in the environment - the waste rock piles and the tailings dam; quantification of the resulting impacts associated to the emission of pollutants into the environment in future scenarios and establishment of remedial actions taking into account the risk reduction and the association costs. The main aspects arising from the study were: the wastes in the tailings dam are stratified in relation to metal and radionuclide concentrations, with the exception of 210 Pb and 226 Ra. The stratification is caused by the oxidation of the residual pyrite in the tailings, and is also related to metal and radionuclide concentrations in seepage water being higher in the upper zone and lower in the deeper zones. Sulfate anion was the only pollutant present in the seepage water to be detected in the groundwater below the tailings dam. Mathematical simulations taking into account the rest of the potential pollutants indicated the probability of groundwater contamination after 800 years. Direct liquid effluent releases into superficial waters are associated with a dose of about 8.0 mSv/y (conservative scenario) and less than 0.62 mSv/y (non-conservative scenario). If houses are built over the tailings, doses as high as 40 mSv/y and 8.0 mSv/y are to expected due to the Rn exhalation and external gamma respectively. Finally, covering the tailings dam with a clay layer 1.0 m thick

  14. Application of environmental management concepts to a nuclear installation: a study case on the uranium mining and milling facilities of Pocos de Caldas, Minas Gerais State, Brazil

    International Nuclear Information System (INIS)

    The objective of this work was to assess the environmental radiological impacts caused by the acid drainage originated in the oxidation of pyritic material in the waste rock dumps from the uranium miming and milling facilities of Pocos de Caldas. It has been determined that uranium isotopes were of major concern in terms of the exposure of the critical population to radioactive elements. Alternatives for the management of this problem were examined and it was concluded that the recovery of uranium from the acidic waters would be the most adequate one in terms of a cost-effectiveness analysis.

  15. Chemical characterization of the quality of water in a dam under the influence of uranium mining, ore treatment unit, Caldas, Minas Gerais, Brazil

    International Nuclear Information System (INIS)

    The Brazilian Nuclear Industries Ore Treatment Unit (UTM/INB), located in the plateau region of Pocos de Caldas - MG, is the first uranium extraction mine to have its deposits explored in Brazil. The Represa das Antas (RA) receives treated acidic effluents from waste rock dumps, originated from acid mine drainage from UTM/INB. At RA's downstream, the Represa Bortolan (RB) - focus of this study - can be located. The dam is characterized by the receiving of domestic and industrial residue discharges, in addition to the RA waters. Within this context, the purpose of the study is to evaluate if the release of the effluents treated by UTM/INB has influence over the chemical quality of the water at RB. Water samplings were carried out at RB in three different periods of the day (9am, 12pm and 4pm), during three consecutive days, on the surface, through and in the bottom of the water column. The evaluated chemical variables were: zinc (Zn), manganese (Mn), fluoride (F-), molybdenum (Mo), sulfate (SO42-), uranium (U), thorium (Th), pH, dissolved oxygen, total phosphorus and total nitrogen. The results indicated that elevated Mn concentrations - above limits established by current legislation in Brazil - can be related to the treated effluent released by UTM/INB, since the metal Mn is one of the chemical components of the effluent in natura. Regarding the other chemical components (F-, Zn, Mo, SO42-, U and Th), related to the acidic effluent's composition as well, their recorded values were found to be within the limits established by current legislation.

    Full Text Available The article has a double aim. It first discusses an approach dealing with the spatial distribution of crime and its theoretical consequences. It is argued that this kind of approach allows us to make an analysis of rational and utilitarian components of crime. This is possible by focusing the attention on local incidences of crime instead of the characteristics of the criminals. Secondly, crime incidence in the 756 cities of Minas Gerais throughout the year of 1991 is analyzed using the theoretical approach mentioned. For that, empirical Bayes indexes are used.

    Full Text Available Rubis e safiras de quatro depósitos em Minas Gerais, denominados Sapucaia, Indaiá e Palmeiras, na região de Caratinga-Manhuaçu, e Malacacheta, mais ao norte, foram caracterizados em termos geológicos, gemológicos, químicos e espectroscópicos, com o objetivo de interpretar causas de cor, gênese, bem como analisar o potencial econômico dos depósitos. Resultados de análises químicas e espectroscopia UV-visível mostram que a provável causa da cor azul é transferência de cargas entre Fe2+ e Ti4+, enquanto Cr3+ causa tonalidades violeta e púrpura, efeito alexandrita e fluorescência. A ausência de Ce e La e o teor relativamente mais alto de Ga distinguem as amostras de Malacacheta das demais. Além de sugerir particularidades genéticas, a diferença em termos de elementos-traços, pode ser utilizada como indicador de proveniência das gemas. Inclusões de um polimorfo de Al2SiO5 e indícios de campo sugerem que o coríndon deve ter sido gerado por processos metamórficos regionais, o que expande as possibilidades para a descoberta de novas ocorrências de rubi e safiras nos terrenos de alto grau metamórfico do leste de Minas Gerais.Rubies and sapphires from four deposits in Minas Gerais named Sapucaia, Indaiá and Palmeiras, in the region of Caratinga-Manhuaçu, and Malacacheta, farther north, were characterized in terms of geology, gemology, chemistry and spectroscopy in order to interpret causes of color and genesis. The economical potential of the deposits was also analyzed. Chemical analyses and UV-visible spectroscopy reveal that the probable cause of the blue color is a charge transfer between Fe2+ e Ti4+, while Cr3+ causes violet and purplish tints, alexandrite effect and fluorescence. Absence of Ce and La and relatively higher Ga-contents distinguish the Malacacheta samples from the others. Besides suggesting genetic particularities, the difference in terms of trace elements might be used as a provenience indicator for the

    Full Text Available No Sul e Sudeste brasileiros, o excesso de chuvas durante o período de maturação afeta negativamente a qualidade dos vinhos tintos. Por outro lado, estas regiões possuem potencial para a elaboração de espumantes, uma vez que, para a elaboração desta bebida, a uva é colhida antes de completar o amadurecimento. No Estado de Minas Gerais, as condições de verão chuvoso estão presentes em todas as regiões de potencial vitícola, e a variação de altitude entre elas pode exercer influência na composição das uvas. Desta forma, este estudo buscou avaliar o potencial de maturação de uvas 'Chardonnay' e 'Pinot Noir' destinadas à elaboração de espumantes em dois locais de Minas Gerais: Cordislândia (873m e Caldas (1.150m. As plantas foram enxertadas sobre 1.103 Paulsen e conduzidas em espaldeira. Foram avaliados os teores de sólidos solúveis totais, acidez total, ácidos málico e tartárico, e pH do mosto, tamanho e massa das bagas, compostos fenólicos nas cascas e sementes, antocianinas na casca e açúcares solúveis nas bagas, em duas safras consecutivas. As bagas apresentaram maior tamanho e massa quando cultivadas em Caldas. As uvas colhidas em Cordislândia apresentaram maior grau de maturação, sendo observados maior pH, maiores teores de glicose e frutose, e quantidade inferior de acidez e fenólicos totais nas sementes. Os maiores teores de ácido málico presentes nas uvas provenientes de Caldas sugerem que esta região pode ser mais indicada à produção de uvas para elaboração de vinhos espumantes.In the southern and southeastern of Brazil, the excessive rainfall during the maturation period negatively affects the quality of red wines. On the other hand, these regions have great potential for the development of sparklings since that for the elaboration of this drink, the grape is harvested before complete its maturation.

    This work was undertaken in order to ascertain the PKU mutational spectrum in Minas Gerais, Brazil, the relative frequency of the mutations in the State and the origin of these mutations by haplotype determination. Minas Gerais is a trihybrid population formed by miscegenation from Europeans, Africans and Amerindians. All 13 exons of the PAH gene from 78 PKU patients were analyzed, including splicing sites and the promoter region. We identified 30 different mutations and 98% of the PAH alleles were established. A new mutation (Q267X) was identified as well. The most common mutations found were V388M (21.2), R261Q (16.0%), IVS10-11G>A (15.3%), I65T (5.8%), IVS2+5G>C (5.8%), R252W (5.1%), IVS2+5G>A (4.5%), P281L (3.8%) and L348V (3.2%). These nine mutations correspond to 80% of the PKU alleles in the state. Haplotypes were determined to characterize the origin of the PAH alleles. The majority of the mutations found, with respective haplotypes, are frequent in the Iberian Peninsula. However, there were some mutations that are rare in Europe and four previously unreported mutation-haplotype associations. I65T and Q267X were found in association with haplotype 38 and may be African in origin or the result of miscegenation in the Brazilian population. PMID:18798839

    Full Text Available Transmission of Leishmania was studied in 27 coffee plantations in the Brazilian State of Minas Gerais. Eighteen females and six males (11.6% of the people tested, aged between 7-65 gave a positive response to the Montenegro skin test. Awareness of sand flies based on the ability of respondents to identify the insects using up to seven predetermined characteristics was significantly greater among inhabitants of houses occupied by at least one Mn+ve individual. Five species of phlebotomine sand fly, including three suspected Leishmania vectors, were collected within plantations under three different cultivation systems. Four of these species i.e., Lu. fischeri (Pinto 1926, Lu. migonei (França 1920, Lu. misionensis (Castro 1959 and Lutzomyia whitmani (Antunes & Coutinho 1939 were collected in an organic plantation and the last of these was also present in the other two plantation types. The remaining species, Lu. intermedia (Lutz & Neiva 1912, was collected in plantations under both the "adensado" and "convencional" systems. The results of this study indicate that transmission of Leishmania to man in coffee-growing areas of Minas Gerais may involve phlebotomine sand flies that inhabit plantations.

    Full text: Intense mining activities in Minas Gerais State - Brazil bring out tons of waste to the environment. Considerable concentration of toxic elements penetrate the soil, ground waters and rivers. This endangers the environment quality not only in the surrounding areas but also occurs in ichthyofauna and in more distant areas of cattle raising and agricultural activities. After seasonal floods, veterinary clinic studies have shown that most animals raised in this region are affected by symptomatologic nervous diseases, still not clearly diagnosed, that suggests intoxication. These pathologies are mostly noted after floods. Instrumental Neutron Activation Analysis - INAA was applied to determine major and trace elements in environmental samples. The obtained results show that the contaminated water and sediment with heavy metals and toxic elements from the Das Velhas River upstream basin, the mining region, carry contamination to the ichthyofauna and farming region within a distance of approximately 400 km.

    Full Text Available This article deals with the development of monoculture index (MI of eucalyptus as a key element for the management of the territory, from the perspective of sustainable development. We analyzed the "geography" of the eucalyptus plantation in Minas Gerais, to support the planning, organization, control and use of territory. The Monoculture index proposed, which is an important tool for land management, was developed and validate by its application to municipalities of Minas Gerais state. It was shown that the culture of Eucalyptus represents a low rate of monoculture in the state of Minas Gerais and that the geography of this culture is compatible with sustainable territorial expansion. Therefore, these results contribute to the definition of public land management in Minas Gerais and the methodology used can be applied to other states.

    Full Text Available Estudos associados a chuvas extremas são constituídos de eventos de interesse prático para a gestão dos recursos naturais, como manejo de bacias hidrográficas e conservação dos solos e da água. A distribuição espacial desses eventos possibilita inferir sobre áreas onde sua ocorrência é acentuada e desprovida de informações técnicas. Os objetivos deste trabalho foram promover, a partir de dados pontuais de 177 estações meteorológicas e com a utilização de técnicas geoestatísticas, o mapeamento de chuvas intensas para o Estado de Minas Gerais e identificar as áreas mais vulneráveis no tocante à ocorrência dessas chuvas nesse Estado. Foi constatado que as maiores intensidades ocorrem nas regiões leste e noroeste de Minas Gerais, o que pode ser explicado pela maior influência da Zona de Convergência do Atlântico Sul, além de ocorrência de chuvas convectivas. Foi possível, também, constatar e mapear intensidades intermediárias nas regiões sul e central e os menores valores para as regiões norte e nordeste de Minas Gerais. Para maiores durações, verificou-se, para a região sul, ocorrência de altas intensidades, o que está associado à entrada com maior frequência de frentes frias, produzindo chuvas de longa duração.Studies of heavy rainfall are of practical interest for the conservation management of natural resources such as watersheds and soil and water. The spatial distribution of these natural rainfall events allows conclusions about regions where the occurrence of heavy rain is more frequent and to estimate their magnitude for locations without rainfall data sets.

    Full Text Available Introduction: Architectural barriers generate difficulties, significantly impair people’s access to different environments, and limit accessibility. In the Brazilian public school system, these questions become more relevant when the process of school inclusion of students with special needs for mobility is analyzed. The process of school inclusion is intrinsically associated with the accessibility condition of schools. Through the ‘Accessible School Program‘, schools have received financial incentive to adapt their physical spaces according to accessibility. Objective: To describe the accessibility of the schools that have taken part in the ‘Accessible School Program’ in the municipality of Uberaba, Minas Gerais state. The study also aimed to identify the materials purchased and the adjustments and repairs implemented, evaluating whether the changes attend the technical standard of accessibility and agree with the recommended proposals. Methodology: This is an exploratory-descriptive study of quantitative nature; it was conducted in two phases through documental research and field study. Eleven municipal schools that participated in the ‘Accessible School Program’ were identified. Results: Most of the schools presented problems in almost all the items evaluated: sidewalks, common inside area, door squares, restrooms, locker rooms, swimming pools, parking, cinemas or theatres, auditoriums, stadiums, gymnasiums, concert halls, conference rooms and school furniture. Conclusion: The public schools evaluated present limitations regarding accessibility; the physical barriers erected in the past have not been eliminated and they still represent obstacles to be overcome by students with special needs.

    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.

    Full Text Available The reference evapotranspiration is an important hydrometeorological variable; its measurement is scarce in large portions of the Brazilian territory, what demands the search for alternative methods and techniques for its quantification. In this sense, the present work investigated a method for the spatialization of the reference evapotranspiration using the geostatistical method of kriging, in regions with limited data and hydrometeorological stations. The monthly average reference evapotranspiration was calculated by the Penman-Monteith-FAO equation, based on data from three weather stations located in southern Minas Gerais (Itajubá, Lavras and Poços de Caldas, and subsequently interpolated by ordinary point kriging using the approach "calculate and interpolate." The meteorological data for a fourth station (Três Corações located within the area of interpolation were used to validate the reference evapotranspiration interpolated spatially. Due to the reduced number of stations and the consequent impossibility of carrying variographic analyzes, correlation coefficient (r, index of agreement (d, medium bias error (MBE, root mean square error (RMSE and t-test were used for comparison between the calculated and interpolated reference evapotranspiration for the Três Corações station. The results of this comparison indicated that the spatial kriging procedure, even using a few stations, allows to interpolate satisfactorily the reference evapotranspiration, therefore, it is an important tool for agricultural and hydrological applications in regions with lack of data.

    Considering the planned closure of the first uranium mine and milling plant operating in Brazil, located in the Pocos de Caldas Plateau, in the State of Minas Gerais, in the next two years, there is the need to obtain basic information for its decommissioning. Special attention has been directed to the following critical areas: open pit, tailing, dam and waste rock piles, because these are the main sources of acid drainage generation. These waters cannot be allowed to flow in the external environment because in addition to sulphuric acid, there is a number of elements in concentration above those allowed by regulations. Among the waste piles (bota-foras BF) two of them BF-4 and BF-8, are in a process of acid generation, thus requiring more attention. The objective of this work was to simulate at the laboratory scale the oxidation and the reduction zones of BF-4. The experiments were conducted in acrylic columns, where the waste sample was kept under aerated and saturated conditions, in different columns. The control of the chemical (solubilized chemical species), physico-chemical (redox potential, pH, conductivity) and biological (bacterial activity) parameters has been carried out on the acid solutions generated by the chemical and biological reactions that occur at the waste. Although the results refer to a four month period, some relevant points can be highlighted, which will serve as a basis for further research. The mineralogical characterization identified the existence of other sulphides associated to pyrite with lower oxidation potential than the latter. The results obtained with the biological characterization for the two conditions studied revealed that the bacterial activity is more intense in the region in contact with air, than in saturated region.

    The article analyzes the role played by engineers in the construction of road infrastructure in Minas Gerais between the 1840s and 1880s. Building and providing regular maintenance for roads and bridges was a task carried out by the Minas Gerais provincial government, which since the 1830s had a specific agency assigned to designing, building, and maintaining public communication routes. Engineers were part of the agency from its inception, playing a significant role in designing projects and in the actual execution of certain works. The current study is grounded in administrative documentation in which the details of work progress are reported to the provincial government. The gathered records provide technical, administrative, and financial information, along with data on labor power and the agents engaged in construction works. PMID:22012105

    Full Text Available The objective of this study was to obtain an estimate for residential electricity demand in Minas Gerais in the period from 1970 to 2002. Specifically, the goal was to estimate price and income elasticities. After determining that the series under study were non-stationary, we chose to use the Co-integration approach, estimating a Vector Error Correction Model (VEC Model. The results obtained show that the demand studied is more sensible to variations in the income than to the price of the electricity, although both elasticities are inferior to the unit. It was also concluded that price-elasticity is higher in Minas Gerais than it is for Brazil as a whole, suggesting differentiated usage of this energy among the different states in the Country.

  8. Crustal structural survey for the state of Minas Gerais, Brazil, utilizing geophysical and geological information

    International Nuclear Information System (INIS)

    Gravity, Magnetic (airborne, Magnet and Magsat), heat flow and seismicity available data for the state of Minas Gerais and adjacent regions is here analyzed, discussed and integrated with geologic information. The Late Archean crustal structure is defined as blocks of granite-greenstone separated by belts of high-grade terrains. The belts in eastern and southern Minas Gerais represent the lower parts of the Vitoria, Sao Paulo and Parana Blocks, which were up thrusted over the Brasilia Block through low-angle ductile simple shear Zones. That regional structure is cut and somewhat displaced by NW, ENE, NE and Ns fault sets. These faults are mostly related to the Transamazonian Event, and their geological expression appears to be as high-angle ductile simple shear zones. The development of the Middle/upper proterozoic folded sequences, the incidence of the Brasiliano/Uruacuano thermo tectonic events and the geometry of the Sao Francisco Craton were highly influenced by the preexistent weakness zones. The high-grade terrains, the borders of the Brasilia Block and the Transamazonian lineaments have been preferentially affected. The tectono-magmatic manifestations of the Wealdenian Reactivation, related to the opening of the Atlantic Ocean, occurred mostly among the uplifted zones (Alto Paranaiba Uplift) that developed partially until the rift stage (Mantiqueira Uplift). These processes clearly reveal the influence of the old structures of the state of Minas Gerais. The Mantiqueira Uplift presents a more accentuated seismic activity and thermal flow regime than the neighboring regions, so corresponding to the present less stable area of Minas Gerais. (DJM)

    Full Text Available The objective was to verify the general behavior of wood density of native tree species in forest types in Minas Gerais state. The trees scaling data were obtained from the Forest Inventory of Minas Gerais State. Were used data from 1988 trees distributed in different forest formations. From each tree, five discs of wood were removed, at the 0, 25, 50, 75 and 100% of the total height. The wood basic density of each disk was determined according to NBR 7190/1997. The ombrophylous forest, semideciduous forest, savanna woodland, typical savanna and deciduous forest presented average wood density of 0.502, 0.561, 0.585, 0.612 and 0.675 g.cm-3, respectively, all statistically different. It was found a clear and consistent relation between wood density and environment characteristics that affect the different vegetation types in Minas Gerais State. The forest formations present environmental conditions so typical that they affect the floristic composition and also the cambial and physiological activity of plants, causing particular wood densities to forests formations.

    Full Text Available Introduction: The lift end of the ban on any press activity in Brazil, 1808, led to the multiplication of newspapers sparking a new impetus not only to a political debate, but also to spread the practice of informational and literary reading. Objective: Investigate the occurrence of reading practices in Minas Gerais, in the 19th century, particularly the newspapers reading in public libraries of the cities of Ouro Preto and São Joãodel Rei. Methodology: It was undertaken a literature review on History of Reading dialoguing with Darnton, Chartier, Abreu, Lajolo and Zilberman. A documentary research has been done involving the use of local newspapers as well as official documents and memoirs of foreign travellers, followed by textual analysis. Results: Even though in a small number Minas Gerais libraries were responsible for facilitating the access of the province inhabitants to reading practices. Newspapers reading, in particular, articulated an important network of communication between readers, publishers and advertisers, creating a channel of political participation and sociability between citizens of different brazilian towns. Conclusions: Minas Gerais social scenery in that moment, as was already happening since the 18th century, on the occasion of the conspiracy movements, did reading newspapers an everyday act lived by individuals of different social classes. In fact, in libraries and literary societies, such as in public squares, diaries and leaflets were read aloud for the benefit of poor and illiterate people who were, in this manner, socially inserted in that moment of social and political changes.

    Full Text Available The Bignoniaceae family has 120 genera and 800 species with pantropical distribution, occurring mainly in the neotropics. About 32 genera and 350 species occur in Brazil, which is considered the center of diversity of the family. In Minas Gerais, some surveys indicate the occurrence of species such as Dolichandra unguis-cati, Fridericia speciosa and Handroanthus chrysotrichus. Lavras studies show 58 species. The municipality is located in a transition zone between savanna and semideciduous forest, with rugged terrain, which promotes a diversity of vegetation physiognomy. The objective was to catalog the species of native and exotic Bignoniaceae of Lavras, Minas Gerais, besides the elaboration of an identification key for them. Data were collected from all herbarium specimens with record collection in the city incorporated in the Herbarium ESAL; species cited in phytosociological studies of the county and registration of ornamental species found in parks, gardens and nurseries of the city were also raised. The specimens were identified in situ, by comparisons, consultations with specialists and specialized taxonomic literature. Fifty eight species (51 native and seven exotic were found, distributed in 21 genera, of which Jacaranda (10 species was the most common, followed by Fridericia (8 species and Handroanthus (7 species. Among the ornamental species stood out Handroanthus impetiginosus (Purple-ipe and Handroanthus serratifolius (Yellow-ipe. The number of species was superior to other localities, the largest similarity observed was with species of Itacolomi State Park, Minas Gerais.

    Full Text Available Mining in the State of Minas Gerais-Brazil is one of the activities with the strongest impact on the environment, in spite of its economical importance. Amongst mining activities, acid drainage poses a serious environmental problem due to its widespread practice in gold-extracting areas. It originates from metal-sulfide oxidation, which causes water acidification, increasing the risk of toxic element mobilization and water resource pollution. This research aimed to evaluate the acid drainage problem in Minas Gerais State. The study began with a bibliographic survey at FEAM (Environment Foundation of Minas Gerais State to identify mining sites where sulfides occur. Substrate samples were collected from these sites to determine AP (acidity potential and NP (neutralization potential. The AP was evaluated by the procedure of the total sulfide content and by oxygen peroxide oxidation, followed by acidity titration. The NP was evaluated by the calcium carbonate equivalent. Petrographic thin sections were also mounted and described with a special view to sulfides and carbonates. Based on the chemical analysis, the acid-base accounting (ABA was determined by the difference of AP and NP, and the acid drainage potential obtained by the ABA value and the total volume of material at each site. Results allowed the identification of substrates with potential to generate acid drainage in Minas Gerais state. Altogether these activities represent a potential to produce between 3.1 to 10.4 billions of m³ of water at pH 2 or 31.4 to 103.7 billions of m³ of water at pH 3. This, in turn, would imply in costs of US$ 7.8 to 25.9 millions to neutralize the acidity with commercial limestone. These figures are probably underestimated because some mines were not surveyed, whereas, in other cases, surface samples may not represent reality. A more reliable state-wide evaluation of the acid drainage potential would require further studies, including a larger number of

    Full Text Available The clinical, pathological, and immunohistochemical findings associated with a vaginal leiomyosarcoma in a 12-year-old, Senepol breed of cow from Uberlândia, Minas Gerais are described. The animal had a large ulcerative neoplastic growth that originated between the base and the left-lateral vaginal wall. Histopathology revealed a tumor formed by muscle-like cells that demonstrated cellular pleomorphism, anisokaryosis, prominent and multiple nucleoli, with rare tumor giant cells. The neoplastic growth invaded adjacent adipose tissue, and contained areas of hemorrhage with discrete accumulations of inflammatory cells. By immunohistochemistry, most neoplastic cells expressed actin, while immunoreactivity to desmin was weakly expressed. These findings support a diagnosis of leiomyosarcoma, and represent the first description of a bovine vaginal leiomyosarcoma from Brazil.No presente trabalho, foram descritos os achados clínicos, patológicos e imunohistoquímicos de uma vaca da raça Senepol, 12 anos, com leiomiossarcoma vaginal, de Uberlândia, Minas Gerais.

    Agricultural expansion is causing deforestation in Minas Gerais, Brazil, converting savanna and tropical dry forest to farmland, and in 2012, Brazil’s Forest Code was revised with the government reducing deforestation restrictions. Understanding the effects of policy change on rates and locations of natural ecosystem loss is imperative. In this paper, deforestation in Minas Gerais was simulated annually until 2020 using Dinamica Environment for Geoprocessing Objects (Dinamica EGO). This system is a state-of-the-art land use and cover change (LUCC) model which incorporates government policy, landscape maps, and other biophysical and anthropogenic datasets. Three studied scenarios: (i) business as usual, (ii) increased deforestation, and (iii) decreased deforestation showed more transition to agriculture from shrubland compared to forests, and consistent locations for most deforestation. The probability of conversion to agriculture is strongly tied to areas with the smallest patches of original biome remaining. Increases in agricultural revenue are projected to continue with a loss of 25% of the remaining Cerrado land in the next decade if profit is maximized. The addition of biodiversity value as a tax on land sale prices, estimated at over $750,000,000 USD using the cost of extracting and maintaining current species ex-situ, can save more than 1 million hectares of shrubland with minimal effects on the economy of the State of Minas Gerais. With environmental policy determining rates of deforestation and economics driving the location of land clearing, site-specific protection or market accounting of externalities is needed to balance economic development and conservation.

    Full Text Available In order to improve the knowledge about variations in the floristic community of Brazilian cerrado, especially inregard to soil and climate conditions, we conducted a floristic assessment of the tree and shrub community of three disjoint adjacentregions situated in three municipalities of southwest Minas Gerais state (geographical coordinates 20-23ºS and 44-47ºW. Over aperiod of 24 months, in 49 allocated plots of 20 x 20 m, all tree and shrub species 1 m high or more in vegetative and/or reproductivestage were sampled. Additional random samples of blossoming plants were collected outside plots, and each plot was analyzed andcategorized for soil type. 170 botanical species were identified belonging to 103 genera and 46 families. Family Fabaceae and genusMiconia presented the largest number of species. Although the cerrado of southwest Minas Gerais extends over marginal areas ofoccurrence of Brazilian cerrado, its floristic composition is rich not only in species but also in genera and families. Some species foundin these cerrados also occur in local semideciduous forests, while other species that are frequently found in other areas of cerrado werenot found in southwest Minas Gerais. Tibouchina sellowiana does not feature in the list of species occurring in Brazilian cerrados.There is little similarity among the three sampled areas due to soil factors and different types of human influence in each of the areas.Alpinópolis presented cerrado sensu stricto subtype cerrado ralo, with 75 species and red-yellow latosol. Campo do Meiopresented cerrado sensu stricto subtype cerrado típico, with 88 species and red latosol. Pimenta falls under the cerradão category,with 124 species and red latosol. On the subsurface, the soil of Pimenta was found to present lower Al+++ saturation, which apparentlyshapes conditions for a more vigorous vegetation. The cerrado soils sampled in this study showed high similarity to cerrado soils inother parts of Brazil.

    Agricultural expansion is causing deforestation in Minas Gerais, Brazil, converting savanna and tropical dry forest to farmland, and in 2012, Brazil's Forest Code was revised with the government reducing deforestation restrictions. Understanding the effects of policy change on rates and locations of natural ecosystem loss is imperative. In this paper, deforestation in Minas Gerais was simulated annually until 2020 using Dinamica Environment for Geoprocessing Objects (Dinamica EGO). This system is a state-of-the-art land use and cover change (LUCC) model which incorporates government policy, landscape maps, and other biophysical and anthropogenic datasets. Three studied scenarios: (i) business as usual, (ii) increased deforestation, and (iii) decreased deforestation showed more transition to agriculture from shrubland compared to forests, and consistent locations for most deforestation. The probability of conversion to agriculture is strongly tied to areas with the smallest patches of original biome remaining. Increases in agricultural revenue are projected to continue with a loss of 25% of the remaining Cerrado land in the next decade if profit is maximized. The addition of biodiversity value as a tax on land sale prices, estimated at over $750,000,000 USD using the cost of extracting and maintaining current species ex-situ, can save more than 1 million hectares of shrubland with minimal effects on the economy of the State of Minas Gerais. With environmental policy determining rates of deforestation and economics driving the location of land clearing, site-specific protection or market accounting of externalities is needed to balance economic development and conservation.

  15. Evaluation of multiple scan average dose (MSAD) levels in computerized tomography in Minas Gerais state, Brazil

    International Nuclear Information System (INIS)

    Computed Tomography (CT) grows every year and is a diagnostic method that has revolutionized radiology with advances in procedures for obtaining image. However, the indiscriminate use of this method generates relatively high doses in patients. The diagnostic reference levels (DRLs) is a practical tool to promote the evaluation of existing protocols. The optimization and the periodic review of the protocols are important to balance the risk of radiation. The present study aims to conduct a survey of levels of MSAD of Minas Gerais following the procedures recommended by current Brazilian law. (author)

A malacologic survey and parasitologic stool examinations were undertaken in 13 municipalities of the mesoregion. A sample of 3,283 primary school students was submitted to fecal examination by the Kato-Katz method. A total of 3,627 planorbids was collected and examined. The molluscs were identified as Biomphalaria straminea in seven municipalities (Unaí, Bonfinópolis de Minas, Paracatu, João Pinheiro, Vazante, Lagamar and Lagoa Grande and as Biomphalaria peregrina in one (Presidente Olegário. All planorbids were negative for Schistosoma mansoni. Four students were diagnosed with schistosomiasis in the municipalities of Buritis, Formoso, Paracatu and Unaí, but none of these cases was considered autochthonous. The data obtained indicate that the "Noroeste de Minas" mesoregion continues to be non-endemic for schistosomiasis mansoni, although the presence of intermediate hosts associated with parasitized individuals emphasizes the need for epidemiological surveillance of schistosomiasis in this mesoregion.

    According to the National Register of Health Care Facilities (CNES), there are approximately 477 mammography systems operating in the state of Minas Gerais, Brazil, of which an estimated 200 are digital apparatus using mainly computerized radiography (CR) or direct radiography (DR) systems. Mammography is irreplaceable in the diagnosis and early detection of breast cancer, the leading cause of cancer death among women worldwide. A high standard of image quality alongside smaller doses and optimization of procedures are essential if early detection is to occur. This study aimed to determine dosimetry and image quality in 68 mammography services in Minas Gerais using CR or DR systems. The data of this study were collected between the years of 2011 and 2013. The contrast-to-noise ratio proved to be a critical point in the image production chain in digital systems, since 90% of services were not compliant in this regard, mainly for larger PMMA thicknesses (60 and 70 mm). Regarding the image noise, only 31% of these were compliant. The average glandular dose found is of concern, since more than half of the services presented doses above acceptable limits. Therefore, despite the potential benefits of using CR and DR systems, the employment of this technology has to be revised and optimized to achieve better quality image and reduce radiation dose as much as possible.

    Giardia duodenalis (syn. Giardia intestinalis and Giardia lamblia) is a widespread intestinal parasite in mammals, including humans and pets worldwide. It should be considered a species complex and comprises eight assemblage (A-H). This works aimed to determine the genotypic variability among G. duodenalis isolates from dogs from Minas Gerais state, Brazil. Fecal samples of 97 dogs, from 1-to-10 months old from 15 commercial kennels, were collected and analyzed by the zinc sulfate centrifugal flotation technique, to determine their positivity for G. duodenalis cysts. Cysts pellets were stored and submitted to PCR and nested-PCR reactions with gdh and tpi primers, and then sequencing. Among positive samples (n = 19), fragment amplifications of gdh and tpi genes was observed in 16 (84,2%) and 14 (73,6%), respectively. In total, 30 sequences were obtained. Sequencing analysis showed that for gdh, all isolates were identified as host-specific genotype D, and for tpi, besides host-specific genotype C, were also observed zoonotic genotypes A and B. This study provides, for the first time, current information about genetic characterization of G. duodenalis isolates found in dogs in Minas Gerais state. PMID:26704664

    Full Text Available Soil erosion is one of the most significant environmental degradation processes. Mapping and assessment of soil erosion vulnerability is an important tool for planning and management of the natural resources. The objective of the present study was to apply the Revised Universal Soil Loss Equation (RUSLE using GIS tools to the Verde River Basin (VRB, southern Minas Gerais, in order to assess soil erosion vulnerability. A annual rainfall erosivity map was derived from the geographical model adjusted for Southeastern Brazil, calculating an annual value for each pixel. The maps of soil erodibility (K, topographic factor (LS, and use and management of soils (C were developed from soils and their uses map and the digital elevation model (DEM developed for the basin. In a GIS environment, the layers of the factors were combined to create the soil erosion vulnerability map according to RUSLE. The results showed that, in general, the soils of the VRB present a very high vulnerability to water erosion, with 58.68% of soil losses classified as "High" and "Extremely High" classes. In the headwater region of VRB, the predominant classes were "Very High" and "Extremely High" where there is predominance of Cambisols associated with extensive pastures. Furthermore, the integration of RUSLE/GIS showed an efficient tool for spatial characterization of soil erosion vulnerability in this important basin of the Minas Gerais state.

    Full Text Available ABSTRACT The objectives of this study were to morphologically characterize fruits of the babassu palm tree (Attalea vitrivir and to estimate their productivity in the north of Minas Gerais State, Brazil. Twenty mature fruits were collected from 10 plants in three different areas in Januária, Minas Gerais. Eighteen biometric parameters of the fruits were measured, the oil contents of the seeds was determined, the adherence to normal distribution was evaluated, distribution frequencies were evaluated and the effects of individuals and areas on the variables and the correlations between them were analyzed. The production of fruit bunches per plant and the number of fruits per bunch from 10 plants were quantified in three areas and the potential production under both natural harvesting and cultivation conditions were estimated. Significant differences were found among all of the biometric parameters examined between the different individuals and the different areas, which shows wide morphological variability in the fruits. The average oil content was 45.7%, but with significant differences among individuals. The observed variability favors the selection of productive individuals in genetic improvement programs. The potential productivity of endocarps and oil based on a density of 400/plants per hectare would be respectively 6.4 and 1.2 tons/ha, which indicates the possibility of using A. vitrivir for producing charcoal, bio fuels, and for carbon fixation.

    Brazil harbors five species of Cypseloidinae swifts. Those from Streptoprocne and Cypseloides genera have a very distinct ecology. They shelter at night and build nests in moist cliffs by waterfalls. Information about tick infestation of these birds is virtually non-existent and restricted to the description of a new species, Ixodes paranaensis, in Streptoprocne biscutata in Paraná State and another record of this species in Streptoprocne zonaris in Minas Gerais State. We herein report tick infestation of swifts at eight waterfalls in the Cerrado biome of Minas Gerais State, southeastern Brazil. Swifts were captured during six campaigns from November 2008 to April 2013. Overall, 584 swifts were captured (527 C. senex, four C. fumigatus and 53 S. zonaris). Four birds were tick infested (prevalence of 0.7 %). Three individuals of C. senex hosted one tick each; a nymph of I. paranaensis, a female of I. paranaensis and a nymph of Amblyomma cajennense. One S. zonaris hosted an I. paranaensis nymph and an Ornithodoros sp. larva (Argasidae). PMID:24696361

    Full Text Available Milk production in the middle region of northern Minas Gerais state is the lowest in the state. However we noticed a considerable growth in recent years. It is important to conduct socioeconomic and generators technicians guiding information for the adoption of policy measures to boost production diagnostics. The aim of this study was to diagnose the production of milk in 30 family dairy farms in Juramento (15 and Montes Claros (15 city, Northern Minas Gerais; by a case study, semi-structured questionnaires that included information about general and sanitary handling, socio-economic characteristics and also surveyed the use of agro-ecological practices in milk production. A systemic approach was used in the application of questionnaires. Out of the 30 properties, 86% have the dairy activity as the main one, followed by 14% of mixed activities. They have low to average technology and most farmers have another source of income in addition to milk production. The absence of agro-ecological practices in the production process was observed in 100% of the properties. It was concluded that milk production in family farms is very widespread, and the main characteristics are of properties with general and sanitary handling problems; the socio-economic characteristics are of families with low to average income and dependent on the milk production to complement it. Regarding the agro-ecological practices, it can be concluded that they were rarely used in the properties surveyed.

    Full Text Available Birds have a wide geographical distribution, invading all environments, terrestrial, aquatic and aerial, is still quite diverse, with a biodiversity of about 9.900 species whose studies have contributed to our knowledge of the vertebrates, especially in ecology, morphology and behavior. The survey of wildlife is an exercise in which a series of observations aimed, just catalog the species that exist in a certain region, however, each time you use most frequently rapid surveys of tropical bird communities to estimate species richness and to determine conservation priorities, since it is extremely important to know the biological resources that an area contains, as well as its relationship with abiotic factors, is essential for the development of the management plan of an area, and basic instrument for the conservation of natural resources. This study aimed to record the number of species existing in the Municipality of Jacutinga, located in the extreme south of Minas Gerais and have knowledge about the risks of extinction of each species cataloged in the city and also the conservation of their habitats. The results obtained in the city of Jacutinga / MG, where 216 species were recorded and most prominent families was of the order Passeriformes, families Tyrannidae, with 27 species and Thraupidae, with 14 species. Therefore, the municipality Jacutinga is a very important area for the southern region of Minas Gerais, by the wide diversity of bird species exist.

  19. Leaching of uranium from the Osamu Utsumi mine wastes, INB Caldas, Minas Gerais, Brazil

    International Nuclear Information System (INIS)

    Mining is one of the leading sectors of the Brazilian economy and as any other anthropogenic activity it generates residues that impact the environment directly. The Osamu Utsumi Mine, which belongs to the Nuclear Industries of Brazil (INB), operated from 1982 to 1995 with the activities of mining and metallurgical treatment of the uranium ore. Since then the INB has as a main environmental problem, the generation of acid mine drainage from wastes having its pH around 3. The chemical treatment of this acid water incurs an extremely high cost and generates a precipitate that is rich in some metals, including uranium. This precipitate has been disposed of in the mine opening and has caused an overload of chemical pollutants and radioactive elements in a place that was not planned to receive this volume of residues and does not meet the necessary condition for the construction of a repository. The content of uranium in the precipitate is approximately 0.25% - similar to the content of the metal found in the ore in the Caetite Mine (BA) - around 0.29%. The recovery of this uranium from the precipitate would generate a total of 150 tons of U3O8. In the present study an alkaline leaching process was carried out aiming at recovering the uranium from sludge samples disposed of for over 20 years. Sodium carbonate and bicarbonate were used as the leaching agents. The experiments were carried out by varying the concentrations of the leaching agents, extraction time and the solid percentage. The other parameters such as temperature, particle size and agitation were kept constant. The results showed that the recovery of the uranium can reach 100% in 24 hours. The uranium concentration in the solutions is around 250 mg.L-1 when using 10% of solids. Preliminary results showed that the recovery of uranium from the sludge would be a feasible practice. The conversion of an environmental liability into a valuable product is one of the most important objectives of this work. (author)

Fruits of 52 plant species were the main item consumed for all tanagers, representing 59.70% of all items in 1330 events, although different proportions in the use of this resource have been found among the bird species. The main plant families found were Myrtaceae with eight species accounting for 22.29% (n=177, and Melastomataceae with seven species accounting for 22.29% (n=177 of fruit intake. The most frequent plant species in the diet was Cecropia glaziovi Snethl. (Cecropiaceae, which made up 17.76% (n=141 of fruit intake of all species of tanagers. Arthropod consumption came second with 22.63% (n=301, but flowers, leaves, nectar, food remains left by tourists and galls were also represented. Several environmental features influenced diet composition. An Asteraceae, Vanillosmopsis erythropappa Schultz, very common in the park, was important for some birds as its flowers attracted arthropods and its branches and leaves were used as a substrate for insectivory. Fruit intake rate, some bird-plant interaction and features of food-handling were also discussed, pointing to the importance of these birds for the structure of the heterogeneous local landscape, possibly through the spread of seeds of different plant species.

    Potassium is present in distinct forms in the soil. The K forms in the soil are characterized by reversible exchanges between compartments and they have different characteristics in regards to availability for plant uptake. The soil's capacity to supply or restrict K to plants is different for each soil and it determines the sustainability of agricultural production and fertilization management. Thus, the goal of this study was to evaluate the K supplying capacity of soils of different mineralogies from Minas Gerais (Brazil, under successive corn cultivation. A greenhouse experiment was carried out in factorial 7 x 6 (seven soils and six rates of K, in a randomized complete block design, with four replications. The corn plants were cultivated during 45 days for seven successive crop cycles in pots. The potassium availability in the soil was evaluated at the beginning and at the end of each crop cycle using Mehlich-1 and Mehlich-3 extractors. All treatments showed significant decreases in soil K content, which affected corn dry matter accumulation. The reserve of K was highest in Ultisols followed by Inceptisols and Oxisols. Contribution of non-exchangeable potassium to the plant nutrition was observed. The K availability in soil measured by Mehlich-1 represented 40% of K uptake by plants, and 61% of K uptake when Mehlich-3 was used.

    Populational flux of the adult phase of Stomoxys calcitrans was observed in the municipal district of Pedro Leopoldo, Minas Gerais, Brazil. Three biocenoses were selected for the study: stable agrobiocenosis, pastural agrobiocenosis and eubiocenosis. The occurrence and the populational flux of the insects, using the Magoon trap for their capture, were established. For each trap located in different biocenoses, a crossbred calf (Bos taurusxBos indicus) approximately 6-month-old was used as "live bait," exposed weekly for 48h in the traps. Of the three agrobiocenoses studied, the stable agrobiocenosis contributed the greatest number of specimens of. S. calcitrans captured, corresponding to 96.9% of the total flies of this species collected. S. calcitrans shows seasonal behavior for approximately 6 months (spring and summer being the rainiest months of the year). The population peaked during the months of November and December. During the months of July and August, there was no capture of flies. PMID:15908125

    Full Text Available Contemporary communication theory favors participation and collective development of meaning. This paper seeks to analyze the forces that favor and inhibit the participative management of communication in the Minas Gerais Treasury Secretary. This is an organizational case study which involved a total of 464 employees at five different hierarchical levels and supervisory candidates. Participants were asked to describe organizational changes which would facilitate participatory communication. In addition to our survey, we analyzed the secretariat’s website. We applied content analysis to both the employee responses and the website analysis. The main categories of analysis were the management of communication and change. Our results suggest that participative communication involves multiple dimensions—institutional, instrumental, structural, and relational, which vary across hierarchical layers. An understanding of these dynamics has implications for managers who seek to implement participative organizational change.

    Full Text Available In this paper we present an analysis of the judgments released by the Court of Appeal of the state of Minas Gerais, regarding claims that have as their central point practices identified as racism, discrimination or prejudice on the basis of race or skin color. By doing so, we aim to answer the following questions: which type of conflict related to race or skin color is judged, and in the second instance, with regards to the Court of Appeal; which acts, words or expressions are present in these cases; which type of arguments are used and which discursive strategies are applied by defendants, victims and judges to manage the conflict. Our results indicate that the legal system tends to decontextualize expressions historically considered as racist, denying that the root of the observed conflicts is racial prejudice.

This study evaluated the influence of altitude on the diversity of these insects in fragments of semideciduous forest in a tropical altitude climate. Three different elevations in southern Minas Gerais, from 997 to 2080 meters, were studied. Sampling was carried out on 24 days in a ten-month period by active collection. A total of 34 species were found, distributed in 11 genera. At Level 01, 27 species were recorded, and at Level 02, there were 19 species, while Level 03 showed 11 species. The most frequent genus in the sudy area was Polybia, This study showed that in high-altitude tropical climate areas above 1800 meters, diversity decreases substantially and that the number of species that nest by swarming and build nests with protective cover increases.

    Full Text Available Research on rainfall and annual daily maximum discharge rates is essential to support decisions during the design of hydraulic structures. This study tested the adequacy of probability functions to predict the probable rainfall and discharge rates of the Aiuruoca River Basin in Minas Gerais State in Brazil. This basin is very important as starting point of the Rio Grande Basin that eventually discharges into the Parana River in the southern region of Brazil at the border with Argentina. It was found that the log-normal two parameters probability function provided the best fit to historical monthly rainfall series. For example, in the month of January, there is a 75% probability that 201 mm of rainfall will occur. This is the month with the highest volume of rainfall in the region. On another hand, for flow rate, the best fit was provided by the log-normal distribution with three parameters.

    In this contribution we report a study of poorly exposed, rhyodacitic welded-ignimbrite deposit from Minas Gerais. A petrographic study of textures indicate high temperature of emplacement. Key features include eutaxitic texture, flattened and agglutinated lapilli and glass menisci. Most of the feldspar minerals and glass are extensively altered to clay minerals, which pseudomorph the original volcanic textures. Glass menisci and spherules suggest a possible process of liquid immiscibility. Immobile trace element distribution indicates a possible link with other post-Palaeozoic felsic volcanic rocks in Brazil, a magmatism interpreted as due to basaltic underplating and partial melting of a hydrous continental crust. A peculiar feature is a high Light REE/Heavy REE ratio. Depletion in heavy rare earth elements is possibly due to a residual HREE-bearing phase in the source. The geologic context of these rocks suggests a Lower Cretaceous age and a tectonic relationship with a continental rifting event.

  19. INAA: metal pollution in the environment of minas gerais state- Brazil

    International Nuclear Information System (INIS)

    Intense mining activities in Minas Gerais State - Brazil bring out tons of waste to the environment. Considerable concentrations of toxic elements penetrate the soil, ground waters and rivers. This endangers the environment quality not only in the surrounding areas but also occurs in ichthyofauna and in more distant areas of cattle raising and agricultural activities. After seasonal floods, veterinary clinic studies have shown that most animals raised in this region are affected by symptomatologic nervous diseases, still not clearly diagnosed, that suggests intoxication. These pathologies are mostly noted after floods. Instrumental Neutron Activation Analysis was applied to determine Al, As, Au, Ba, Br, Ca, Cl, Co, Cr, Cs, Cu, Fe, Hg, K, La, Mg, Mn, Na, Nd, Rb, Sb, Sc, Sm, Th and Zn in environmental samples. The obtained results show that the contaminated water and sediment with heavy metals and toxic elements from the Das Velhas River upstream basin, the mining region, carry contamination to the ichthyofauna and farming region within a distance of approximately 400 km. Researches to study environmental pollution greatly advanced mainly because of need for answers to various phenomena observed in natural waters, in the living beings that depend on them. Instrumental Neutron Activation Analysis has been widely employed for the determination of multielemental concentrations in the environment. The diversity and abundance study of aquatic fauna species in control and mining affected areas, correlated with physical and chemical factors of the water and sediment, will serve as another environmental indicator of water quality resources in Candiota region, Brazil, which receives important metallic loads originated from point (industrial and domestic effluents) and diffuse sources (coal mines and mining waste and ashes disposal areas) and constitute the area of potential influence for investigation. Industrial waste from mining, chemical industries and metal processing are

    In the lakes of the Middle Rio Doce, Minas Gerais (MG), two groups of larval Libellulidae are distinguished by preferences of habitat use: one uses mainly aquatic macrophytes and the other uses the bottom substrate. The goal of this work was to verify if there is a morphological distinction between the two groups of species. Thirteen body measures were taken from the larvae and analyzed. No difference was found between the two groups of species regarding the body size, but shape differences were observed for two morphological variables. The species that use mainly macrophytes tend to have larger relative measures of the labium and smaller measures of the abdomen width. Advantages in resource obtainment and in vulnerability to predation are probably the explanations for the morphological divergence among these larval groups. PMID:18470400

  1. Contribution on the Northeastern Minas Gerais geologic-geochronologic study, Brazil

    International Nuclear Information System (INIS)

    This work demonstrates the potential of integrated Rb-Sr, K-Ar, and U-Pb determinations, when applied to basic regional geology. The different interpretative values of these methodologies contribute to the understanding of the tectonic processes developed in the south-eastern border of the Sao Francisco Craton (northeastern Minas Gerais). The Brazilian Orogenic Cycle is characterized in the area by the Salinas metasediments and the gneissic-migmatitic rocks of the eastern sector. Rb-Sr and U-Pb data indicate the generation of most or even all of these rocks in the 660-570 Ma, interval. No indications of ancient terrains were obtained, and previous ideas of a pervasive reworking of an Archean or Lower Proterozoic crust must be discarded. The K-Ar analyses indicate a crustal level in which temperature remained above 250O C until at least 480 Ma. (author)

    Full Text Available Only one species of spotted fever-group rickettsiae that is pathogenic for humans has been isolated in Brazil, where few physicians are familiar with this disease. In order to obtain information on tick-borne rickettsiosis, a study was performed in the County of Santa Cruz do Escalvado, State of Minas Gerais, Brazil, where a fatal clinical case confirmed by specific immunofluorescence had been reported. Serum samples obtained from 679 humans and 96 dogs were tested by indirect immunofluorescence for detectable antibodies to spotted fever-group rickettsiae, the criterion for a positive result being a titer > or = 1:64. Seropositivity was detected in 7.14 of the humans sera examined and 13.68 of the dogs. We discuss the significance of these findings and formulate some questions, emphasizing the need for further investigation.

    High spatio-temporal resolution optical remote sensing data provides opportunities to monitor and discriminate burned area in a accurate way. This study has the purpose to assess the discriminatory performance of multi-spectral reflectance values of PROBA-V sensor and on normalized difference spectral indices (NDSIs), such as the Normalized Difference Vegetation Index (NDVI) in burned land discrimination a in different land-cover types across Minas Gerais state, Brazil. The M separability index was calculated in each land-cover type including Cerrado (Tropical Savanna), Atlantic Forest, agricultural crops, and pastures, to determine the most powerful band(s) combinations among the PROBA-V reflective bands for discrimination between burnt and unburnt areas The results showed that the BLUE channel is potentially effective for burntarea discrimination in the majority of all land cover types ,. Moreover results showed that spectral indexes used for discriminating burned areas are vegetation type dependant.

  4. The geotectonic evolution of the Northeastern Minas Gerais, based in geochronological interpretation

    International Nuclear Information System (INIS)

    This work tries to show the potential of the Rb-Sr, K-Ar, Pb-Pb and U-Pb methods applied to basic geological maping. The different interpretative values of these methodologies contribute to the understanding of the tectonic processes developed in the southeastern border of the Sao Francisco Craton (northeastern Minas Gerais and southern Bahia). The geochronological data for this region represents sampling of the several lithological units characterized and corresponds to about 230 determinations. The radiometric age distribution pattern together with other geological information suggest the subdivision into two main geochronological domains: the external Brazilian domain (at the western portion) and the internal Brazilian domain (at the center-eastern part).

    The Cerrado is the second largest Brazilian biome and is listed as one of the hotspots for biodiversity conservation priority. The biome provides important ecosystem services such as maintenance of the biodiversity, water cycle and carbon storage, and your preservation is essential to protecting the Amazon Rainforest. Although its importance, it was heavily affected by deforestation, with a loss of about 49% of its original native cover by the year of 2010. In Minas Gerais state, the remaining Cerrado original cover is very expressive, shaped by a mosaic of phytophysionomies, comprising grassland, savanna and forest. The great species diversity and endemism in these landscapes, associated with changes imposed by man over time, caused major environmental damage in this biome. Recently, new deforestation fronts have been identified throughout the Brazilian Cerrado, including Minas Gerais State. This study aimed to analyze the landscape structure in front of expansion in this state, as a subsidy for the establishment of guidelines for future biodiversity conservation and landscape planning. The study site comprised the sub basins of the Paracatú River (SF7) and Middle São Francisco (SF9). The analyses were performed based on land use, mapped through remote sensing techniques, resulting in 18 classes of land use. The most important results of the calculated indices showed that the study area is highly fragmented, with most of the remaining patches small, with large perimeter and strong edge effect, favoring biodiversity loss. Moreover, the biological flow in the study area is hindered by the presence of few fragments into a predetermined radius of 10 km. It has been found that less than 30% of the native vegetation remnant in the area, making all existing fragments relevant to conservation. Finally, the landscape metrics analyzed showed that there is a high level of environmental risk determining low support existing biodiversity in the landscape.

    Full Text Available Today the management of solid waste and wastewater is a major concern for humanity. In the last decade, traces of pharmaceuticals have been reported in the water cycle and have raised concerns among regulators, water suppliers and the public regarding the potential risks to human health. This study evaluated solid waste management in the state of Minas Gerais and concluded that the main fate of hazardous waste has been incineration, while the non-hazardous waste has been recycled or sent to landfills. However, complaints to the Environmental Agency - FEAM have indicated that a significant number of companies just send their hazardous wastes to landfills or even to garbage dumps, thus highlighting the urgent need for adequate waste management in Minas Gerais. Most of the pharmaceutical companies in Minas Gerais use conventional wastewater treatment. Mass spectrometry with electrospray ionization (ESI-MS showed that the treatment routes adopted by the two 2 selected pharmaceutical industries were not effective enough since residues and degradation products of antibiotics were detected. The physicochemical analysis of the effluents showed variability in their characteristics, which may influence their treatability. The degradation assay with Fenton's reagent stood out as a promising route in achieving a higher removal capacity compared to the conventional treatment. This study contributes to enhancing our knowledge of the management of wastewater as well as of solid waste from the pharmaceutical industry in Minas Gerais and points out the need for further research.Atualmente, a gestão de resíduos sólidos e águas residuais é uma grande preocupação para a humanidade. Na ultima década, a detecção de traços de medicamentos no ciclo da água tem sido reportada e tem gerado preocupação entre os agentes reguladores, fornecedores de água e público devido os riscos potenciais para a saúde humana.

OBJETIVO: Avaliar o custo-benefício da implantação do serviço de telecardiologia em municípios remotos, de pequeno porte, no estado de Minas Gerais, Brasil. MÉTODOS: O estudo utilizou a base de dados do Projeto Minas Telecardio (MTC, desenvolvido de junho/2006 a novembro/2008, em 82 municípios do interior do estado. Cada município recebeu um microcomputador com eletrocardiógrafo digital, com possibilidade de envio dos traçados e comunicação com plantão de cardiologia em pólo universitário. A análise custo-benefício foi realizada comparando o custo de realização de um ECG no projeto MTC ao custo de realizar este exame por encaminhamento em outra localidade. RESULTADOS: O custo médio de um ECG no projeto MTC foi de R$ 28,92, decomposto em R$ 8,08 referente ao custo de implantação e R$ 20,84 ao de manutenção do programa. A simulação do custo do ECG com encaminhamento variou de R$ 30,91 a R$ 54,58, sendo a relação custo-benefício sempre favorável ao programa MTC, independente da forma de cálculo da distância de encaminhamento. Nas simulações, foram consideradas as abordagens do financiador e da sociedade. A análise de sensibilidade com variação dos parâmetros de calibração confirmou esses resultados. CONCLUSÃO: A implantação de sistema de telecardiologia como apoio a atenção primária em cidades brasileiras de pequeno porte é factível e economicamente benéfica, podendo ser transformada em programa regular do sistema público de saúde.

  13. [The creation of hospitals by charities in Minas Gerais (Brazil) from 18th to 20th century].

    Marques, Rita de Cássia

    2011-01-01

    This article is the fruit of research into the cultural heritage of healthcare in Minas Gerais (Brazil) and explores the construction of hospitals supported by Catholic charities from the 18th to 20th century. Catholicism has always been strong in Minas Gerais, partly because the Portuguese Crown prohibited the free travel of priests, who were suspected of illegally trading in gold from the mines. A brotherhood was responsible for creating the first Santa Casa, in Vila Rica. Another very important religious group in Brazil, the Vincentians, was also devoted to charitable works and propagated the ideas on charity of Frederico Ozanan, based on the work of St. Vincent de Paul. This group comprised both a lay movement, supported by conferences organized by the St. Vincent de Paul Society, and a religious order, the Vincentian priests and nuns. Catholic physicians make up the third group studied here, organized in a professional association promoted by the Catholic Church. The brotherhoods, Vincentians, and associations, with their Santa Casas, represent a movement that is recognized worldwide. The enormous Catholic participation in these charitable works brought in the physicians, who would often make no charge and exerted efforts to create hospitals that served the population. Although the capital of Minas Gerais was the creation of republicans and positivists in the 20th century, with their ideas of modernity, it remained dependent on Christian charity for the treatment of the poor.

    Full Text Available The present study contributes to identifying obstacles to the development of a local biodiesel agro-industrial system (AGS in the state of Minas Gerais, Brazil. The research questions are: “How do local social characteristics influence the organizational effectiveness of agents involved in the joint production effort?”; and “How can the institutional arrangement of biodiesel production be described?” The method adopted is the case study, focused on family farmers served by the Family Farmers Rural Extension and Technical Assistance Company (EMATER. This state organization introduced castor beans (Ricinus communis L. to family farmers as an alternative crop to supply a processing plant (Darcy Ribeiro Biodiesel Plant—DRBP in northern Minas Gerais state, Brazil. These family farmers are not horizontally organized, and sign individual contracts with DRBP. The paper concludes that the primary obstacle to developing the biodiesel AGS with castor beans in Minas Gerais is the lack of horizontal organization among family farmers.

    Full Text Available Entre 1750 e 1880, Minas Gerais desenvolveu economia com o predomínio de direção não exportadora da produção e relativa independência em relação a mercados externos de outros espaços regionais do Brasil e do exterior do país. Essa singular evolução histórica ensejou específica compreensão e tratamento do problema dos transportes pelos contemporâneos. No século XIX, sobretudo em seu terceiro quartel, estavam postas as condições para que o processo de modernização dos transportes em Minas, sobretudo na forma da aceleração da constituição de sistema integrado, se realizasse fora das determinações da hegemonia de modelo econômico primário-exportador. Neste escrito, são avançadas reflexões em torno da história dos transportes na província de Minas Gerais e apresentadas e analisadas evidências documentais que demonstram o quanto pode ser equivocada apreensão da modernização dos transportes no Brasil que considere modelo único ou que tenda a generalizar para o conjunto do país a experiência histórica da modernização com base no ferroviarismo.Between 1750 and 1880, Minas Gerais developed an economy predominantly non-exporting as well as relatively independent of external markets of other Brazilian regions and of foreign markets. Due to such unique historical evolution, contemporaries had to develop specific understanding and ways of dealing with transportation problems. In nineteenth century, mainly in its third quarter, it were established the conditions for the modernization process of transportation in Minas. Those conditions allowed such modernization to take place apart from the determinations resulting from the hegemony of a primarily exportation economic model, specially based on hastening the construction of an integrated system. This text enlarges considerations about the history of transportation in the province of Minas Gerais. It presents and analyses documental evidences which demonstrate it can

  2. Chemical-mineralogical characterization and Moessbauer spectroscopy of aquamarine from Pedra Azul, Northeast of Minas Gerais

    International Nuclear Information System (INIS)

    Aquamarines from three pegmatites located the vicinities of the Pedra Azul city, Minas Gerais state, were investigated in terms of chemical composition, physical properties and Moessbauer spectroscopy. The small lenticular pegmatite bodies are usually less than 5 m wide and exhibit a conspicuous mineralogical and textural zoning. The last thermal event in these pegmatites, determined by K-Ar method in muscovite, is of Neo proterozoic age, coincident with the late stages of the Brasiliano tectono- metamorphic cycle. Chemical analyses showed that sodium is the alkali with higher contents in the aquamarines, thus enabling their classification as sodic beryls. In zoned samples there is an increase of Fe as well as Mn from center to border, while no systematic variation could be detected for other elements. The specific gravity of 2.72 to 2.80 g/cm3 is higher than the values determined for samples from other pegmatites of Minas Gerais. The refraction indices are ne=1.569 - 1.579 and NW= 1.573 - 1.581 and the birefringence varies from 0.002 to 0.008. The refraction indices increase with the Be O content. The color of aquamarines varies from medium to light blue, sometimes greenish blue. Moessbauer spectra obtained at room temperature and at 80 K show that Fe2+ is the main chromophore-ion and suggest that the iron is present in octahedral sites as well as in the structural channels. Moessbauer spectra also indicate that the incorporation of Fe3+ may cause a shift from deep blue to light blue colors. Based on their aquamarine composition the pegmatites were classified as barren, poor in rare alkalis (Li, Rb, Cs) and therefore little differentiated. The relatively simple mineralogy and the lack of lithium minerals such as lepidolite and spodumene confirm this classification. Thus, the composition of beryl can be used as a tracer for the prospection of pegmatites with different degrees of differentiation and consequently with different types of mineralization. (author)

    Full Text Available OBJECTIVE: To analyze the profile of tuberculosis cases reported between 2002 and 2009 in the state of Minas Gerais, Brazil, according to sociodemographic, clinical, and laboratory characteristics, as well as to comorbidities and mortality. METHODS: This was a descriptive, epidemiological study based on data obtained from the Brazilian Case Registry Database and the Brazilian Mortality Database for the 2002-2009 period. RESULTS: There were 47,285 reported cases of tuberculosis, corresponding to a mean incidence of 22.3/100,000 population. The individuals diagnosed with tuberculosis were predominantly in the 20- to 49-year age bracket and male (62.4% and 67.0%, respectively. Individuals with a low level of education accounted for 18.5% of the cases. New cases, cases of recurrence, and cases of retreatment accounted for 83.7%, 5.7%, 5.7%, respectively. The rates of cure and treatment noncompliance were 66.2% and 11.2%, respectively; multidrug-resistant tuberculosis was identified in 0.2% of the cases; and the mortality rate was 12.9%. The directly observed treatment, short-course (DOTS strategy was applied in 21.8% of the cases. Sputum smear microscopy and culture were performed in only 73.9% and 12.9% of the cases, respectively. Chest X-rays were performed in 90.5% of the cases. Pulmonary tuberculosis was the predominant form (in 83.9%. Comorbidity with alcoholism, HIV infection, and diabetes mellitus were identified in 17.2%, 8.3%, and 3.8%, respectively. CONCLUSIONS: During the study period, the numbers of new cases, cases of treatment noncompliance, and deaths were high, comorbidities were common, and there was a failure to perform adequately basic tests for the diagnosis of tuberculosis. Multidisciplinary approaches, expanded use of the DOTS strategy, better knowledge of the distribution of tuberculosis, and improvements in the databases are needed in order to achieve better control of the disease in the state of Minas Gerais.

    Full Text Available A participação de Lavras na oferta de banana no mercado local é muito pequena, considerando-se que o Brasil é o segundo país maior produtor com 6,6 milhões de toneladas e Minas Gerais é o quarto entre os Estados produtores dessa fruta. Visando a quantificar a participação de Lavras e região na oferta de banana no mercado local, realizou-se esse trabalho em duas etapas: 2002/2003 e 2004/2005. A aplicação mensal de questionários nos principais estabelecimentos comerciais de hortifruti e feiras - livre de Lavras, permitiu conhecer o volume comercializado, procedência e perdas das principais cultivares de banana. Os resultados obtidos mostram que em 2002/2003 foram comercializados 945,24 t e em 2004/2005 foi de 1.001,98 t. Desse volume, 6,56% em 2002/2003 e 14,62% em 2004/2005 tiveram como origem Lavras. O consumo per capita anual manteve-se em torno de 11,8 kg nos dois períodos pesquisados. As bananas tipo 'Prata', foram as mais comercializadas nas duas etapas, 54,7% no primeiro período e 58,7% no segundo, sendo que 7,91% e 18,35% , respectivamente, tiveram como origem Lavras. O volume de banana 'Marmelo' e do tipo 'Nanicão', foram de 1,91% e 28,4%, respectivamente, sendo que 84,0% da 'Marmelo' e 3,43% da tipo 'Nanicão' na segunda etapa foram procedentes de Lavras. A banana 'Maçã' teve uma redução de 125,30 t para 107,47 t, correspondendo a 13,26%, sendo que a oferta dessa cultivar, originada de Lavras, manteve-se em 13,8%. As bananas 'Maçã' e 'Marmelo' apresentaram as menores perdas, 3,56% e 4,78% e as dos tipos 'Prata'e 'Nanicão'as maiores perdas, 9,39% e 10, 75%, respectivamente.The participation of Lavras in the banana production offered to the local commerce is still very low considering that Brazil is the second banana producer of the world, with a production around 6.6 ton/year and per-capita consumption of 24.4 kg/year. Minas Gerais ranks in the fifth place among the most important Brazilian state producers. This

    Full Text Available Abstract Fasciola hepatica is a parasite that affects the hepatic ducts of several species of domestic and wild vertebrates, causing huge economic losses to livestock rearing worldwide. Reports on occurrences of F. hepatica in capybaras are an important epidemiological aspect of this disease, since these rodents can be a source of contamination for other animals and humans. In the present study, conducted in a rural area of the municipality of Confins, Minas Gerais, fresh feces from capybaras were collected from the ground near a lagoon at the edge of the Ribeirão da Mata river. These were examined using the technique of four metal sieves. F. hepatica eggs were recovered. This trematode species was confirmed by observing morphological characteristics and measuring the eggs recovered from the capybara feces, and through experimental infection of Lymnaea columella (Say, 1817 by miracidia from these eggs and subsequent infection of C57/BL06 mice with metacercariae originating from these infected mollusks. The data suggest the occurrence of natural cycle of F. hepatica in this region and provide a warning that expansion of the geographical distribution of this parasite by means of this rodent is possible. It is therefore important to adopting measures for epidemiological control of this helminthiasis.

    Full Text Available A study on the phlebotomine sand fly fauna in Belo Horizonte city, state of Minas Gerais, Brazil, was carried out. From April 2001 to March 2003, monthly systematic collections were performed in three houses from each of the nine regions of the city, using CDC light traps for four consecutive days. The traps were set into the houses and in peridomestic areas totaling 54 traps. A number of 3871 sand fly specimens of the genera Lutzomyia and Brumptomyia were collected. Sixty eight percent of the specimens were L. longipalpis and 16% L. whitmani, insect vectors of visceral and American cutaneous leishmaniasis, respectively. Environmental factors such as temperature, humidity, and frequency of precipitation suggest that the number of insects increases after rainy periods. During the same period mentioned above, seasonal captures were carried out in parks and green areas of Belo Horizonte, using Shannon trap. A total of 579 phlebotomine sand flies were collected from which 398 (68.7% were females with the predominance of L. whitmani and L. monticola. Those specimens were used for natural infection examination, by polymerase chain reaction. No Leishmania DNA was present in any of the specimens tested.

    Full Text Available Geographical information systems (GIS are tools that have been recently tested for improving our understanding of the spatial distribution of disease. The objective of this paper was to further develop the GIS technology to model and control schistosomiasis using environmental, social, biological and remote-sensing variables. A final regression model (R² = 0.39 was established, after a variable selection phase, with a set of spatial variables including the presence or absence of Biomphalaria glabrata, winter enhanced vegetation index, summer minimum temperature and percentage of houses with water coming from a spring or well. A regional model was also developed by splitting the state of Minas Gerais (MG into four regions and establishing a linear regression model for each of the four regions: 1 (R² = 0.97, 2 (R² = 0.60, 3 (R² = 0.63 and 4 (R² = 0.76. Based on these models, a schistosomiasis risk map was built for MG. In this paper, geostatistics was also used to make inferences about the presence of Biomphalaria spp. The result was a map of species and risk areas. The obtained risk map permits the association of uncertainties, which can be used to qualify the inferences and it can be thought of as an auxiliary tool for public health strategies.

    Full Text Available Existe uma grande dificuldade em aperfeiçoar as técnicas de manejo de formigas cortadeiras, sobretudo no que diz respeito aos sauveiros externos localizados próximos a plantios florestais. Por causa disso, o presente trabalho teve por objetivo caracterizar aspectos como tamanho e distância de sauveiros externos em plantações de eucaliptos. A avaliação foi realizada em aceiros externos de três fazendas localizadas nos municípios de João Pinheiro e Buritizeiro, em Minas Gerais, seis meses após ser realizado o combate convencional às formigas cortadeiras. Foram encontrados nove sauveiros externos, com área média de terra solta de 62,5 ± 11,1 m2, localizados a uma distância média de 33,94 ± 8,68 metros entre a margem do plantio e o local do formigueiro. Constatou-se que tais características podem ser úteis no ajuste da largura da faixa de segurança de combate, a qual deve ser igual a 50 m. O gênero Trachymyrmex e as espécies Atta laevigata e Atta sexdens rubropilosa foram registrados como ocorrências novas no município de Buritizeiro, e o gênero Acromyrmex como uma nova ocorrência nos dois municípios.

  14. Radiation protection in dental radiological diagnosis at Minas Gerais State, Brazil

    International Nuclear Information System (INIS)

    Since 1995 the Divisao de Protecao Radiologica do Centro de Desenvolvimento da Tecnologia Nuclear (CDTN) of the Comissao Nacional de Energia Nuclear (CNEN) applies radiological surveys in diagnostic rooms and also applies tests in the x-ray machines in compliance with the legal requirements. In 1998 the work was adapted to match the requirements of the Portaria 453 'Diretrizes de Protecao Radiologica em Radiodiagnostico Medico e Odontologico' de 01/06/1998 da Secretaria de Vigilancia Sanitaria. From 1998 until March 2002, the radiological surveys carried out by CDTN reached 261 dental X-ray machines for intraoral radiographs. Among them 27% showed non conformities with the standards prescribed for the machines or for the rooms. Inadequacies for the patient protection were found, namely, the value of the skin entrance dose higher than the reference level, the inadequacy of the half value layer and the x-ray field diameter higher or lower than the interval prescribed. This work analyses the results of these three tests and gives an overall view of the radiation protection conditions of the dental facilities in Minas Gerais. (author)

    The stingless bee Melipona rufiventris is an important pollinator in several Brazilian ecosystems. Originally widely distributed in Minas Gerais (MG) state, this species is becoming very rare. Therefore this species was included in the endangered species list of MG. We used isoenzyme data for a better understanding of the genetic structure of several M. rufiventris colonies. Samples of 35 colonies were collected from 12 localities and evaluated by nine enzymatic systems, which yielded 17 loci. M. rufiventris genetic variation was found to be low, typical of an endangered species. The proportion of polymorphic loci was 5.88% in both ecosystems. Only Est-4 was polymorphic in colonies from the Forest and Mdh-1 in colonies from the Cerrado. The expected heterozygosity ranged from 0.0068 in the Cerrado to 0.0078 in the Forest. Despite this, enzyme electrophoretic analyses provided a good idea of the diversity between samples from Cerrado and Forest which reinforce the existence of two different "forms" of M. rufiventris in MG, one present in the Cerrado and the other in Forest. This information is of great importance for the conservation of M. rufiventris in MG. PMID:15859519

It was carried out in the town of Nova Porteirinha. One tested 7 treatments, using 6 gross sum (GS values (1,000; 1,300; 1,600; 1,900; 2,200, and 2,500 and the systematic disease control every 15 days. The treatments were distributed into 7 plots (120 plants/plot with ‘Prata-Anã’ and 10 plants from each plot were weekly evaluated with regard to leaf emission rate and disease incidence on the leaves 2, 3 and 4. The more advanced lesion stages and their intensity were used to calculate the gross sum, which aided in decision-making for chemical control. One collected data on production and firmness, pH, and acidity analysis of fruits. For the GS 2,500 treatment, taking into account 2-year evaluation, there was a reduction from 12 to 3 applications, i.e. 75% less fungicide was applied, without loss in productivity. Therefore, one suggests, taking into account the conditions of Nova Porteirinha, the application of BFS for chemical control of Yellow Sigatoka, using the GS value of 2,500 as an indicator of the correct time to perform pulverization.

    Full Text Available Between October, 1997 and September, 1999 in Belo Horizonte, Minas Gerais a study of seasonal variation of Lutzomyia longipalpis was carried out in three distinct areas of the municipality. Sand flies were sampled at 15-day intervals in three residences, in each of which two CDC light traps were installed, one indoors and the other in the peridomicile. A total of 397 sand flies were captured in the three areas, with 65%, 30% and 1% of specimens collected in the eastern, northeast and Barreiro districts, respectively. The overall proportions of sand flies collected inside and around the houses were similar (57% vs 43% and this pattern was seen for both Lutzomyia longipalpis and Lutzomyia whitmani . The highest population levels during the two years of the study were from October to March. From October onwards, numbers increased constantly until February. A gradual fall was seen from April onwards until the lowest levels were reached in the months of June, July and August.

    Full Text Available ABSTRACT: The cultivation of mulberry ( Rubus sp. is highly disseminated in cold climates, but some cultivars adapt to warm weather environments. The objective of the present study was to evaluate the production of blackberry and redberry in season and off season in Pouso Alegre, south of Minas Gerais. The experimental design was a randomized block, with twelve cultivars ('Arapaho', 'Xavante', 'Brazos', 'Tupy' 'Comanche', 'Choctaw', 'Guarani', 'Caingangue', 'Cherokee', 'Chicasaw' and 'Clone' and a redberry, three blocks and an experimental unit of four plants with a spacing of 0.5x3.0m and a total density of 6,666 plants per hectare. Conventional pruning was performed to produce the crop (October-December and for off-season production (April-July. In 'Brazos' there was increased production in the two seasons evaluated against other mulberry trees, conversely, in the off season, there was a positive effect of pruning carried out in January only in 'Tupy', 'Choctaw', 'Comanche' and 'Clone', with 'Tupy' presenting the highest productivity off season. In 'Brazos' and 'Tupy' there was the best balance between soluble solids and acidity in the crop and red berry in season. 'Brazos' and 'Cherokee' had the highest average content of total sugars. Due to the lack of supply of fruit, pruning mulberry trees in January is an alternative to increase the income of family-based farms.

  19. Tectonic-thermal evolution from the northeast region of Minas Gerais and South of Bahia

    International Nuclear Information System (INIS)

    The northeast region of Minas Gerais and South Bahia are centered to the east of 420 00'WGr, between parallels 150 and 180. Its tectonic-thermal evolution is presented here with the support of stratigraphy/lithology, structural analysis, petrography, petrochemistry, regional metamorphism/retro metamorphism and radio chronology. It is pointed out that the evolution occurred in a mobile belt initiating its history in the terminal Archean up to Inferior Proterozoic. The northeast of the region attained crustal stability during 1700 My up to 1800 My (Sao Francisco Craton) meanwhile the rest of the zone kept mobilized till upper proterozoic times. Radio chronological studies suggest for the post tectonic granitic rocks, ages from the brasiliano cycle as well as for those pre-existing rocks which suffered isotopic regeneration and metamorphose in that same cycle an original age from Archean to inferior proterozoic times, except for those which are situated in the northeast part of the region. Petrochemical data point to an origin from sedimentary processes for the majority of the metamorphosed rocks in this region. (author)

    International Nuclear Information System (INIS)

    Iron oxides are dominant minerals in many geo-domains of economical interest, as iron ore mines. Knowing the main mineral transformation pathways is a fundamental step to plan prospecting new mineral deposits. This study aimed at contributing to a better understanding of the chemical and mineralogical processes related to the genesis and transformations of iron oxides involving hematite in an iron-ore mine of the east border of Quadrilatero Ferrifero, Minas Gerais, Brazil. Two representative geo-samples were analyzed with synchrotron radiation X-ray diffraction (XRD), 57Fe Moessbauer spectroscopy, X-ray fluorescence and saturation magnetization (σ) measurements. The iron content varied from 65 to 69 mass% Fe. From XRD data, hematite is indeed the major mineral for all samples but characteristic reflections of goethite and magnetite also appear. For the magnetic sample, σ = 6.9 J T-1 kg-1. 298 K- and 110 K-Moessbauer data allow characterizing hematite in these iron-rich geo-materials.

    Contents of total mercury, organic carbon, total sulfur, iron, aluminum and grain size and clay mineralogy were used along with Pearson's correlation and Hg thermal desorption technique to investigate the presence, distribution and binding behavior of Hg in soils from three depths from the Tripui Ecological Station, located near Ouro Preto, Minas Gerais State, Brazil. The soils studied had predominantly medium and fine sand texture (0.59-0.062 mm), acid character and Hg contents ranging from 0.09 to 1.23 {mu}g/g. The granulometric distribution revealed that Hg is associated with coarse sand (2-0.59 mm) and silt and clay (<0.062 mm) and presents similar Hg concentrations in both fractions. Mercury distribution in soil profiles showed that Hg was homogeneously distributed throughout the depths at most sites. Hg thermal desorption curves show that mercury occurs not only as Hg{sup 2+} predominantly bound to organic components in most of the samples, but also in the form of cinnabar in some. Pearson's correlation confirmed that mercury is associated with organic matter and sulfur and possibly with sulfur-bearing organic matter in most samples. (author)

Os resultados apontam para a importância de fatores econômicos e políticos. Aparentemente, militantes pró-reforma agrária se adequam ao ciclo político, causando menos conflito em municípios governados por aliados. Por sua vez, a pobreza e o elevado crescimento arrefecem o ímpeto desses militantes.The article analyzes the determinants of the probability of dispute over land (conflicts, occupations and settlement projects in the Brazilian state of Minas Gerais. Through the use of a logit model, we found that the main influences are political and economical ones. Apparently, the behavior of the agrarian reform's supporters follows the political incentive, with fewer occurrences of conflicts in towns governed by political allies. By other hand, the economical determinants - degree of poverty and the economic growth - have negative impacts on it.

  5. Trace elements in feldspars and micas in granite pegmatites from northern Minas Gerais

    International Nuclear Information System (INIS)

    A contribution to the geochemistry of granite pegmatites in Minas Gerais, Brazil is presented. Special emphasis is given to trace element contents in feldspars and muscovites of 25 different pegmatites and their geochemical significance. 180 potassium feldspars 110 albites and 64 muscovites have been analized. It could be demonstrated, that the trace element distributions in feldspars taken along cross-sections through some pegmatite bodies, show some regularities in those, which have a relatively simple mineralization. Other ones with a more complex composition are more characterize by a lack of these conformities. Potassium feldspars from pegmatites with a significant phosphate compound, on the average include more than 0.30% P2O5. Those of pegmatites with an extend Li-admixture contain more than 90 ppm Li. These observations may be useful to help classificate little known pegmatites in respect to economical purposes. Late formed muscovites from highly differenciated pegmatites contain beyond others - increased contents of Zn and Ga. This, too, may be a useful indicator to the further discovery of these kind of pegmatites, mostly enriched in minerals of economic interest. (Author)

    A fragment of a Schneiderhoehnite crystal, found at Urucum pegmatite, at the State of Minas Gerais, Brazil, was studied by x-ray crystallography. Schneiderhoehnite, Fe8 As10 O23, was described previously as triclinic. The cell parameters for the original sample, found at Tsumeb, South West Africa, were: a0 = 8.940 ± 0.004 Angstrom, α = 63.00 ± 0,003deg; b0 = 9.998 ± 0.004 Angstrom, β = 116.20 ± 0.003deg; c0 = 9.145 ± 0.005 Angstrom, γ = 81.79 ± 0.003deg. The experimental value for the density of the mineral was found to be 4.3 g.cm-3 and the density calculated by using the parameters is 4.40 g.cm-3. The results here reported suggests an alternative unit cell for Schneiderhoehnite which, despite of being yet triclinic, presents reticular parameters somewhat different from those reported previously that is, a0 9.034 Angstrom, α = 56deg 23'; b0 = 9.689 Angstrom, β = 124deg 14'; c0 = 9.944 Angstrom, γ = 98deg 13'. The density of Schneiderhoehnite calculated with these parameters should be 4.47 g.cm-3. This value compares favourably with the experimental value (4.3 g.cm-32). (author). 5 refs, 2 tabs

    Full Text Available ABSTRACT: This study aimed to evaluate the growth of rubber tree clones ( Hevea brasiliensis (Willd.exA.Juss. Müll. Arg. in the Northwest region of Minas Gerais, Brazil. Randomized blocks, constituted of three treatments (rubber tree clones and four repetitions were used, and evaluated as plots subdivided in time. Subplots represent the evaluations carried out at the ages 62, 77, 87, 99, 113 and 128 months after planting. It was evaluated survival, stem circumference and total plant height. Current annual increment and average annual increment of circumference and also the number of trees fit for rubber tapping were calculated. Results obtained indicate that clones GT 1, IAN 2880, IAC 15, RRIM 600, PB 235 and IAN 3156 have potential to establish under local edaphoclimatic conditions. Increase in plant height and stem circumference throughout the evaluation period makes it evident that the clones have different growing paces in the studied region. Clones GT 1, IAN 3087, IAN 3156 and PR 255 had larger stalk circumference at 128 months, and PR 255 was the only one fit for rubber tapping at the age of 128 months after planting.

    Full Text Available Objective: To identify from pediatric dentistry educational experiences and knowledge concerning child abuse/neglect, numbers of suspected cases of child abuse and knowledge of local child protection. Method: A survey with 26 pedodontics in Araguari and Uberlandia (Minas Gerais, Brazil was done and they were sent a postal questionnaire, 17 responded, giving a 65.4 percent response rate. The survey requested demographic details, responses to possible physical abuse or neglect, and details of suspected child abuse reporting behavior. Results: In their working lives 52.9 percent said that they had seen a suspicious child physical abuse case; however, only 14.3 percent had reported a suspicious case to the authorities. Twenty-nine percent of dentists did not know their legal responsibility concerning reporting child abuse; and 61 percent did know where to report child abuse. Conclusion: Due to lack of training, most practitioners were unsure what to do in the event of a suspicion of child abuse. There is need for continuing education of dentistry practitioners regarding symptoms and signs of physical abuse and the role of dental team in the multidisciplinary management of child abuse. Dental curricula should be revisited to ensure that students are adequately prepared for this professional task.

    Full Text Available Water erosion is responsible for soil, water, carbon and nutrient losses, turning into the most important type of degradation of Brazilian soils. This study aimed to evaluate the influence of three cover plants under two tillage systems on water erosion control in an Argisol at south of Minas Gerais state, Brazil. The cover plants utilized in the study were pigeon pea, jack bean and millet, under contour seeding and downslope tillage. Experimental plots of 4 x 12 m, with 9% slope, under natural rainfall were used for the quantification of losses of soil, water, nutrients, and organic matter. One experimental plot was kept without plant cover (reference. Higher erosivity was observed in December and January, although a great quantity of erosive rainfall was detected during the whole raining period. Contour seeding provided a greater reduction of water erosion than downslope tillage, as expected. The jack bean under contour seeding revealed the lowest values of soil, water, nutrients and organic matter losses.

    Full Text Available The present study aimed to determine the spatial and temporal rainfall in Minas Gerais State relating to their respective rainfall weather systems and to identify homogeneous regions. The method of Factorial Analysis in Principal Components and Hierarchical Grouping were used to determine the seasonal and spatial patterns and homogeneous groups of rainfall. It was observed that the three first principal components describe 80.4% of the total variance of rainfall observed, in that the first factor explains 34.3% of the variance and showed high correlations with the rains from December to April in the southern State, which is influenced, mainly by the performance of frontal systems. The second factor explains 26.6% of data variance and showed significant correlations with rainfall from May to September in the northwest and southwest, and is possibly related to cold fronts and the South Atlantic Convergence Zone. Finally, the relative contributions to the third factor, with 19.5% of data variance accounted for the months of October and November, and are associated with mesoscale and microscale systems. Four homogeneous regions in relation to seasonal and interannual variability of rainfall were found. It concludes that statistical methods tested showed satisfactory results for this type of analyze, corroborates previous studies.

    An increase in groundwater consumption in the municipality of Sete Lagoas (Minas Gerais, Brazil) has induced subsidence and collapse in the last three decades. The area is associated with natural karst conditions. The primary objective of this research was to evaluate and identify the potential subsidence or collapse risk zones. Aerial photographs, lithologic well profiles, optical well logs, and geologic mapping were utilized to categorize risk factors influencing karst subsidence and collapse, which were then applied to an index system. The study showed that the majority of the urbanized area overlies mantled limestone from the Sete Lagoas Formation covered with unconsolidated sediments, contained within a graben, resulting in barrier boundaries for groundwater flow. This structure, together with natural karst processes, explains the location of solutionally enlarged bedding-plane conduits and high hydraulic conductivity in the limestone. Five risks zones in the municipality were identified (negligible, low, moderate, considerable, and high risks) related to geologic and hydrologic risk factors. The urbanized area is located largely in the high risk zone where the majority of the collapse features are located. Additional intensive groundwater extraction in that area will likely generate additional events.

    Full Text Available OBJECTIVE: This study aimed at identifying associations between the participation of transfusion services in immunohematology external quality control programs and their accuracy in immunohematology testing and adaptation to technical and legal operational procedures. METHODS: From 2007 to 2009, a cross-sectional study was conducted in 219 transfusion services of the State of Minas Gerais who participated in this investigation by responding to a questionnaire and conducting a proficiency test comprising: ABO and RhD phenotyping, irregular RBC antibody screening and cross-matching. Frequencies and bivariate analysis followed by binary logistic regression were used for statistical analysis. RESULTS: Transfusion services who participated in external quality control programs (32.4% and those that did not (67.6% obtained worrying error percentages in proficiency tests which may significantly increase blood transfusion risks. Shortfalls related to the establishment of protocols, standards and internal quality control were also significant. On comparing the two groups, transfusion services that participated in these programs had a 2.35 times higher chance of correct results in the proficiency panel testing, a 3.16 higher chance of having transfusional records and a 2.81 higher chance of performing preventive maintenance of equipment. CONCLUSIONS: The study showed that independent factors associated to participation in external quality control programs suggest that more investment in internal quality control procedures is necessary and that more attention should be paid to current legislation.

    Full Text Available A study to determine the sociocultural factors influencing knowledge, attitudes, and practices of individuals from a small community toward Schistosoma mansoni infection was carried out in an endemic area in the State of Minas Gerais, Brazil. The study used qualitative approaches to collect data from school-aged children and teachers. Specific findings were that the individuals interviewed were aware of the disease, but also held inaccurate popular beliefs about transmission. Misconceptions coexisted with accurate knowledge both in children and teachers. The disease was not seen as a major health problem and did not affect their activities since it did not cause severe symptoms in most of the individuals. Although the majority of the participants related transmission to water and lack of sanitation, they did not take any preventive measures since their subsistence is highly dependent on irrigation, farming, fishing, and other essential work that is directly related to water activities. The authors discuss the development of a health education program based on the knowledge and perception of individuals about the disease and its determinants as being important for the context and behavioral change.

    Full Text Available This article analyzes the representations of rural and urban youngsters on the subject of aids. It aims to verify if the intensification of the interaction between country and city that provides increasing access to both spaces results in a symbolic homogeneity on some aspects of the disease. The technological progress and the physical mobility advance promote this approach, which provides information to rural youngsters that put them in situations of consonance of attitudes and vulnerabilities in comparison with the urban youngsters. The research used data based on the sample of 131 students from the Curso Técnico em Agropecuária of the federal institute IF Sudeste de Minas Gerais – Campus Barbacena – amongst whom 40 residents in rural areas. The results reveal that the youngsters assume they are aware of aids, but their responses to the questionnaire betray a state of high vulnerability to the disease. The analysis is guided by the social representation theories and shows that stereotypes about diseases remain instilled in the symbolic countryside, collaborating to the convergence of opinions and conducts.

Aqui, contudo, os objetivos são distintos, apesar de suas fontes arquivísticas permanecerem inescapavelmente as mesmas.

Sob esta perspectiva, ao invés de repetir, mais uma vez, a história das expedições ao interior do Brasil, o que aqui se busca é encontrar o lugar que estas expedições ocuparam nesse processo de conquista e ocupação territorial, que logo em seguida tornaram possível a articulação, tanto da costa com os sertões, quanto dos diferentes sertões entre si.This article aims at reviewing the history of the conquest and occupation of the San Francisco river valley, in Minas Gerais. The definite version of which was established more than a century ago, in several chapters concerning a the geographical expansion, as named by Basílio de Magalhaes; or b the territorial history, by Felisbelo Freire; or c the ancient routes and settlement of Brazil, as in Capistrano de Abreu. Here, meanwhile, the objectives are quite different, despite their archival sources be inescapably the same. It is assumed that in the second half of the sixteenth century the process of conquest of the territories occupied by indian tribes settled in the right bank of the San Francisco river had come to an end.

    Full Text Available The microbiological profile of whey from the queijo-de-minas (Minas padrão and mozzarella type cheeses produced in four of five most important regions of Minas Gerais state was studied. The contamination percentage found is serious, mainly in terms of the result found in coliforms count at 45ºC e coagulase-positive Staphylococci. The contamination of the whey would be too high, indicating the material as unsuitable for human consumption as well as for industrial means. Due to the lack of a specific identity and a quality pattern for cheese whey, the results can be taken as a base for standard developments, which are seen as necessary concerning the microbiological quality of such products.

    Computed Tomography (CT) grows every year and is a diagnostic method that has revolutionized radiology with advances in procedures for obtaining image. However, the indiscriminate use of this method generates relatively high doses in patients. The diagnostic reference levels (DRLs) is a practical tool to promote the evaluation of existing protocols. The optimization and the periodic review of the protocols are important to balance the risk of radiation. The present study aims to conduct a survey of levels of MSAD of Minas Gerais following the procedures recommended by current Brazilian law. (author)

    Minas Gerais state, Brazil, has experienced severe water scarcity in some areas, demanding large-scale water balance studies to subsidize water policies. The reflectance bands from the MOD13Q1 MODIS product were used together with gridded agrometeorological data in the state, during the year 2014, later extracting the main agriculture growing regions, North, Northwest and Minas Triangle, for analyzes. Precipitation (Prec) and reference evapotranspiration (ET0) data from 36 weather stations were interpolated, while for actual evapotranspiration (ET), the SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm was used. Two climatic water balance indicators were applied, the Water Balance Ratio (WBr = Prec/ET) and the Water Balance Difference (WDd = Prec - ET). The daily net radiation (Rn) was retrieved from surface albedo (α0), air temperature (Ta) and shortwave atmospheric transmissivity (τsw), while the ground heat flux (G) was estimated as a fraction of Rn. For surface moisture, the evapotranspiration ratio (ETr = ET/ET0) and the evaporative fraction [Ef = λE/(Rn - G)] were used, with the latent heat flux (λE) obtained by transforming ET into energy units. Analyzing WDr and WDd, the most water scarcity critical MODIS 16-day periods, reaching to minimum values lower than 1.0 and -10 mm, respectively, were from the end of April to the middle of October. Higher water availability, detected by these indicators larger than 1.5 and 10 mm, respectively, were from the middle of October to the end of December. The maximums WDr and WDd of 7.0 and 158 mm happened from the middle of November to the start of December in the Northwest agricultural growing region. However, according to the ETr and Ef values, after this period, the soil moisture storage showed a gap, increasing only in the second half of December, when they reached to averages of 0.63. The largest values of these last soil moisture indicators, above 0.70 in May, did not coincided with the period

    Full Text Available Com o objetivo de fazer um diagnóstico dos viveiros municipais do Estado de Minas Gerais, foi enviado um questionário a todos os seus 853 municípios, contendo perguntas sobre infra-estrutura, tamanho, existência de responsável técnico, qualificação e treinamento de viveiristas, técnicas utilizadas na propagação das plantas, sistema de irrigação, dentre outros aspectos. Pelos resultados, obtidos nas 270 respostas, foi constatado que grande parte dos municípios estudados não possui viveiros para produção de mudas, o que permite inferir que elas são adquiridas de terceiros ou que não está havendo arborização nas ruas. Nos municípios que possuem viveiros constatou-se que a infra-estrutura verificada é insuficiente e que não há profissionais de nível técnico em sua maioria. Além disso, o treinamento de funcionários poderia ser mais efetivo, uma vez que eles são em grande parte, fixos, embora com baixa escolaridade. Observou-se também que as plantas são propagadas basicamente por sementes e estacas, tendo como finalidade a arborização urbana e a recuperação de áreas degradadas e de matas ciliares, e que são destinadas, principalmente, para doação. Na maioria dos municípios os conhecimentos acerca dos tratos culturais necessários à produção de mudas com características desejáveis à arborização urbana são incipientes.

  10. Rural tourism as risk factor for the transmission of schistosomiasis in Minas Gerais, Brazil

    Full Text Available Recently, the booming rural tourism in endemic areas of the state of Minas Gerais was identified as a contributing factor in the dissemination of the infection with Schistosoma mansoni. This article presents data from six holiday resorts in a rural district approximately 100 km distant from Belo Horizonte, MG, Brazil, where a possibly new and until now unperceived way of transmission was observed. The infection takes place in swimming pools and little ponds, which are offered to tourists and the local population for fishing and leisure activities. The health authorities of the district reported cases of schistosomiasis among the local population after visiting these sites. As individuals of the non-immune middle class parts of the society of big urban centers also frequent these resorts, infection of these persons cannot be excluded. A malacological survey revealed the presence of molluscs of the species Biomphalaria glabrata and Biomphalaria straminea at the resorts. The snails (B. glabrata of one resort tested positive for S. mansoni. In order to resolve this complex problem a multidisciplinary approach including health education, sanitation measures, assistance to the local health services, and evolvement of the local political authorities, the local community, the tourism association, and the owners of the leisure resorts is necessary. This evidence emphasizes the urgent need for a participative strategic plan to develop the local tourism in an organized and well-administered way. Only so this important source of income for the region can be ensured on the long term without disseminating the disease and putting the health of the visitors at risk.

  11. Determination of soil screening levels for natural radionuclides in Minas Gerais state, Brazil

    International Nuclear Information System (INIS)

    Soil screening levels express the levels of contaminant concentration in the soil, which guide the actions to be taken following investigation to confirm contamination. The list of toxic substances or elements under Brazilian legislation includes organics, volatile organics and metals but does not consider radioactive elements. Radioactive elements are all potentially carcinogenic and therefore need to be subject to legal control. The National Nuclear Energy Commission, the federal agency currently responsible for legislation regarding the control of Naturally-Occurring Radioactive Material (NORM) facilities does not establish guiding values for intervention in terms of soil activity concentration in the case of contamination with radioactive elements. In mining, the processing and treating of ores such as cassiterite, uranium, phosphate, niobium, and rare earths contribute to the generation of large amounts of NORM residues. Obviously, the improper disposal of these materials may lead to situations that result in soil and groundwater contamination and unnecessary exposure of the population in general. In order to establish guiding values for soil quality for natural radionuclides in the state of Minas Gerais, the study area included the entire state, which has unique characteristics related to the lithology, genesis, and morphology of the soils. These characteristics have tremendous influence on the petrogeochemistry of elements and radionuclides. A total of 110 soil samples were collected and analyzed in order to determine the activity concentration of U, Th, 226Ra, 228Ra e 210Pb. In general, it was possible to verify that the activity concentrations of U are higher than those of Th. This fact can be explained by the intense weathering that most of the state's soil has undergone and the chemical and geochemical characteristics of the two elements.

    Dengue is a major worldwide public health problem, especially in the tropical and subtropical regions of the world. Primary infection with a single Dengue virus serotype causes a mild, self-limiting febrile illness called dengue fever. However, a subset of patients who experience secondary infection with a different serotype can progress to a more severe form of the disease, called dengue hemorrhagic fever. The four Dengue virus serotypes (1–4) are antigenically and genetically distinct and each serotype is composed of multiple genotypes. In this study we isolated one Dengue virus 1 serotype, named BR/Alfenas/2012, from a patient with dengue hemorrhagic fever in Alfenas, South Minas Gerais, Brazil and molecular identification was performed based on the analysis of NS5 gene. Swiss mice were infected with this isolate to verify its potential to induce histopathological alterations characteristic of dengue. Liver histopathological analysis of infected animals showed the presence of inflammatory infiltrates, hepatic steatosis, as well as edema, hemorrhage and necrosis focal points. Phylogenetic and evolutionary analyses based on the envelope gene provided evidence that the isolate BR/Alfenas/2012 belongs to genotype V, lineage I and it is probably derived from isolates of Rio de Janeiro, Brazil. The isolate BR/Alfenas/2012 showed two unique amino acids substitutions (SER222THRE and PHE306SER) when compared to other Brazilian isolates from the same genotype/lineage. Molecular models were generated for the envelope protein indicating that the amino acid alteration PHE 306 SER could contribute to a different folding in this region located within the domain III. Further genetic and animal model studies using BR/Alfenas/2012 and other isolates belonging to the same lineage/genotype could help determine the relation of these genetic alterations and dengue hemorrhagic fever in a susceptible population.

    Full Text Available The experience described here is part of an extensive program that aims to stimulate schools to develop health integrated projects from theme generators, i.e., themes that have a meaning for the community. It was developed in Jaboticatubas, a town in the metropolitan region of Belo Horizonte, capital of the state of Minas Gerais, Brazil, and the focus was schistosomiasis. The selection was based on the expressive and historical prevalence of this disease in the county, which has been known as the "capital of schistosomiasis", in a national press release since the 1960's. Schistosomiasis is also a theme pointed out by teachers as requiring more information and methodologies to work with their students, most of them living in areas of high risk of transmission. In addition, during the last years, this disease has been transmitted silently through an increasing rural tourism in that region, requiring integrated and effective control actions. The developed strategy included four schools, whose teachers, students, and families took part in the process. It emphasizes in a critical pedagogy approach, which focuses on health issues as themes that may mobilize the school community and awake the population to a work which integrates environment, health, and citizenship. The results demonstrate that teachers and students not only acquired new knowledge and methodological skills, but also gained confidence in their ability to improve their health conditions. Thus, the project promotes a critical education that can result a more permanent effect on the control of schistosomiasis as well as other benefits for the schools and for the population.

    Recently, the booming rural tourism in endemic areas of the state of Minas Gerais was identified as a contributing factor in the dissemination of the infection with Schistosoma mansoni. This article presents data from six holiday resorts in a rural district approximately 100 km distant from Belo Horizonte, MG, Brazil, where a possibly new and until now unperceived way of transmission was observed. The infection takes place in swimming pools and little ponds, which are offered to tourists and the local population for fishing and leisure activities. The health authorities of the district reported cases of schistosomiasis among the local population after visiting these sites. As individuals of the non-immune middle class parts of the society of big urban centers also frequent these resorts, infection of these persons cannot be excluded. A malacological survey revealed the presence of molluscs of the species Biomphalaria glabrata and Biomphalaria straminea at the resorts. The snails (B. glabrata) of one resort tested positive for S. mansoni. In order to resolve this complex problem a multidisciplinary approach including health education, sanitation measures, assistance to the local health services, and evolvement of the local political authorities, the local community, the tourism association, and the owners of the leisure resorts is necessary. This evidence emphasizes the urgent need for a participative strategic plan to develop the local tourism in an organized and well-administered way. Only so this important source of income for the region can be ensured on the long term without disseminating the disease and putting the health of the visitors at risk. PMID:15486645

    Eriocnema fulva Naudin is a perennial herb, endemic to Minas Gerais state, SE Brazil, found on humid, shaded rocky riverbanks in montane semideciduous seasonal forests. The species is threatened, but information regarding its biology is still lacking, although such information is fundamental to any management plan. We aimed to evaluate the reproductive system of Eriocnema fulva in the Jambreiro Forest (19 degrees 58'-59' S and 43 degrees 55'-52' W, 800-1100 m altitude), municipality of Nova Lima, by experiments carried out in 1997 and 1998. The flowers are white, and flowering is of the steady state type, occurring once a year from November to December. Anthers are poricidal, and pollen is the only resource for visitors. The chromosome number is n = 17 during meiosis. The species is self-compatible, but does not produce fruits by spontaneous self-pollination or agamospermy; it requires pollen vectors and buzz pollination in order to produce fruits. Cross-pollination is the main reproductive strategy of E. fulva, and is accentuated by the small number of flowers (one or two in each plant) opened per day. Although the population studied was shaded by forest canopy, the seeds needed light to germinate. Germination ratio was lower in germination cabinet on filter paper (14% after 30 days) than in greenhouse on soil brought from the forest (47% after 25 days). Although the fruit is a capsule and the seeds are small, dispersion (anemochory or hydrochory) does not seem to occur at long distance, as it is the case for other Melastomataceae species with similar syndrome.

    Full Text Available Background and Objectives: Bucking the trend worldwide, in Brazil there is a tendency of increase in the number of AIDS cases, justifying the holding of local epidemiological studies providing subsidies for solving them. This study aimed to analyze the epidemiological profile of AIDS in Contagem, Minas Gerais, between 2007 and 2011, with reflections on educational practices for its prevention and control. Methods: This is a descriptive epidemiological study of historical time series. For the 651 new AIDS cases reported in SINAN from 2007 to 2011, it was calculated incidence rate and average rates and performed stratified analysis by gender, education, age and year of occurrence. Results: The mean annual incidence rate of AIDS and the average annual death rate per 100,000 population was 21.0 and 4.0 cases, respectively. The sex ratio (2.16: 1 remained significant (p ≤ 0.05 for the entire series. The feminization of the disease has been verified. Regarding education, 11 people (3.7% were illiterate, 162 (54.0% had up to elementary school, 84 (28.0% had through high school and 43 (14.3% had to higher education (p = 0.05. Conclusions: In the investigated municipality, AIDS showed an oscillatory pattern, with increased number of cases and may present a strong social determination. This indicated the need to intensify prevention and control of disease, which can be done with the use of educational approaches within the APS and educational institutions. KEYWORDs: Epidemiology.

    Medical staff during interventional radiology could be exposed to radiation conditions that may cause very high dose levels depending on the X-ray machine operational conditions. The dose levels received by medical staff during interventional radiology are very high depending on the operational conditions and the patient trunk thickness. Dose levels could reach a factor of 30 for fluoroscopy or cine modes. The ALARA principle, which emphasizes the adoption of techniques and procedures to keep dose levels as low as reasonably achievable, should be followed to minimize the risk of radiation exposure to medical professionals. Dose reduction could be achieved by persuading the medical staff to wear protection devices (lead apron, thyroid protector, eyeglasses and gloves). Additionally, medical staff should also be persuaded that they should not be submitted to very high doses, above the acceptable limits for occupational workers. Dose levels at hemodynamics services in Minas Gerais State, Brazil, were analyzed. Due to the equipment characteristics or the exam type and conditions X-ray machines were used with 70-120 kV, 2.5-699 mA and 80-2880 s. Annual individual doses were estimated based on measured doses during a specific exam taking into account the workload. Maximum doses varied from 0.05 to 0.70 mSv per exam. The results projected for one work-year period show that all annual individual doses would be higher than the annual dose limit of 20 mSv/y with only a few values lower than 50 mSv/y. Dose levels measured at medical staff positions during hemodynamic exams showed that if the protective devices are not used professionals could be exposed to dose values higher than annual dose limits.

    Full Text Available O artigo trata da instituição das capelas no território das Minas Gerais, considerando a sua significação política e a sua relação com o enquadramento social da população. Procura-se avaliar essa prática de poder, desde a fundação pelos patronos coloniais até o reconhecimento eclesiástico e régio. Observando-se os laços políticos na segunda metade do século XVIII, verifica-se ainda que as capelas, mecanismos de poder senhorial e de normalização dos súditos, tinham um papel fundamental na governamentalidade do Estado, especialmente nas fronteiras.This paper is concerned with the establishment of chapels in Minas Gerais, taking into account its political meaning and its relationship with the social fitting of the population. Power practices are evaluated, since foundations of the chapels by colonial sponsors to their ecclesiastical and royal admissions. Considering political bonds on the second half of the eighteen century, one verifies that chapels - a way of power of owners and subject regulation - had a fundamental role in the government, mainly at frontiers.

    Full Text Available O período que compreende os anos de 1820 a 1850 marca o início da construção e da estruturação de uma política de instrução pública com objetivo de educar o povo da província de Minas Gerais. Este artigo procura analisar o nível de relação entre esse processo e o segmento mais expressivo dentro da estrutura demográfica de Minas Gerais, ou seja, a população negra livre. Para realizar a análise, utilizamos como referência uma documentação censitária que tentou contabilizar a população de todos os distritos mineiros e registrou as crianças que estavam nas escolas. A partir do registro censitário, construímos um perfil racial das escolas, confrontando-o com informações fornecidas por outros documentos (listas de professores, relatos de viajantes, memórias que revelaram uma presença majoritária dos negros nas escolas de instrução elementar. A interpretação que produzimos em relação à presença dos negros nas escolas mineira indica que essa instituição era um dos elementos acionados por esse grupo com objetivo de afirmação no espaço social. Em relação a isso, destaca-se o fato de que a escolarização adquiriu significados específicos em meio à população negra, ou seja, representava a sua inserção na cultura letrada, mas também uma forma de demarcar um distanciamento do mundo da escravidão e uma demonstração de domínio dos códigos de conduta das pessoas livres.The period between 1820 and 1850 marks the beginning of the construction and structuring of a public education policy that aimed at educating the people of the province of Minas Gerais. The present article analyzes the relationship between this process and the most expressive segment within the demographic structure of the province at that time, namely, the population of free blacks. In order to conduct this analysis, we have sought reference in a census documentation that attempted to cover the whole population of Minas Gerais districts

    Full Text Available Fasciolosis is a parasitic disease which is caused by digenetic trematodes, such as Fasciola hepatica, and which occurs worldwide. The disease causes significant economic losses in cattle because of the reduction in milk and meat production and because the parasitized livers have no economic value. Also, abortion and mortality rates increase. To determine the occurrence and dispersal of F. hepatica in the state of Minas Gerais, fecal samples were collected from bovines aged 12 months and older between April 2005 and April 2006. The bovines came from 1,251 rural farms of 120 municipalities/cities in Minas Gerais. Water was collected to ascertain the presence of the intermediate host in the properties where infected bovines were found. A total of 16 municipalities had infected bovines and 13 had the presence of Lymnaea columella. We detected infected bovines in 70% of the rural farms visited in the municipality of Itajubá. Itajubá was also found to have infected snails with the larval stage of F. hepatica. The results revealed that infection by F. hepatica in bovines of Minas Gerais was associated with the presence of the intermediate host and favorable epidemiological factors, drawing attention to the necessity of adopting proper control measures in the area.A fasciolose é uma doença parasitária que ocorre em todo o mundo e é causada por um trematódeo digenético conhecido como Fasciola hepatica. A doença é responsável por causar perdas econômicas significativas em bovinos, devido à diminuição na produção de carne e leite, condenação de fígados parasitados e aumento na mortalidade. Para determinar a ocorrência e a dispersão da F. hepatica no estado de Minas Gerais, amostras de fezes de bovinos com idade superior a 12 meses foram coletadas, no período de Abril de 2005 a Abril de 2006. Foram examinados bovinos provenientes de 1.251 propriedades rurais de 120 municípios do estado de Minas Gerais. Coleções hídricas tamb

    occurrence of vitamin A deficiency in school children of the rural area of Novo Cruzeiro, Minas Gerais, Brazil, as well as to identify the possible predisposing factors for such occurrence. METHODS: The sample comprised 241 school children, ranging from 6 to 14 years of age, from four rural schools of the region. The serum levels of retinol were interpreted by the criteria of the Interdepartmental Committee on Nutrition National Defense. The epidemiological significance of the vitamin A deficiency was evaluated according to the World Health Organization criteria. As predisposing factors for vitamin A deficiency, the following conditions were considered: intestinal parasitism, protein-energy malnutrition, inadequate ingestion of vitamin A food sources, and per capita family income. Statistical analysis was carried out using Chi-square test. RESULTS: Vitamin A deficiency was identified in 29.0% of the subjects, 23.2% of the children presented stunting, and 8.7% were malnourished, according to the body mass index. In 63.1% of the subjects, inadequate ingestion of retinol sources was verified, while 78.8% of the subjects presented some type of intestinal parasite. Most school-children families (87.1% had per capita monthly incomes bellow ¼ of the minimum wage; the rest of the families were situated respectively in the ranges: (10.4%>¼ to ½ to 1 minimum wage. CONCLUSION: Vitamin A deficiency among school children was found to be a public health problem in the studied area. Nonetheless, no significant statistic association between vitamin A deficiency and the factors selected as predisposing ones was observed.

    Full Text Available Cryptosporidiosis is a waterborne disease, has as aggravating the difficulty of preventing environmental contamination and lack of effective therapeutic measures. With marked importance to the cattle, causes inflammation and intestinal villous atrophy resulting in loss of absorptive surface. This study aimed to perform molecular characterization of Cryptosporidium spp. in calves in the city of Formiga, Minas Gerais. A total of 300 faeces samples from Holstein calves, Nelore and indefinite breed, both healthy, were evaluated by negative contrast staining technique of malachite green and through the reaction of nested PCR for amplification of DNA fragments of the 18S subunit of the RNA gene ribosomal. Occurrence of 5.33 % ( 16/300 for malachite green and 4.66 % ( 14/300 by PCR was observed, whereas no correlation was found between positive and variables studied. Through molecular characterization were identified Cryptosporidium andersoni and Cryptosporidium ryanae species. In conclusion, we observed a low incidence of infection and elimination of Cryptosporidium spp. oocysts, the absence of clinical signs in animals, strong agreement between the results obtained by the two techniques. Beyond, with the molecular characterization ( nested PCR , species of C. andersoni and C. ryanae were diagnosed in age groups not present in the literature. These two species of Cryptosporidium are described above for the first time parasitizing cattle in the state of Minas Gerais.

    Full Text Available The presence of the woman in the labor market is a movement that accented through the decades. However, some studies about gender relations have shown that this movement don't occur in any organizations areas and positions. So, this study had the objective to analise the presence of the women instructors at management positions on federal universities in the state of Minas Gerais. Thereby, a qualitative research was conducted, in which the data were collected through secondary fonts and analysed by frequency distribution. It was possible to indetify that, in the federal universities in which the survey occurred, most management roles are occupied by men instructors, mainly in high-level hierarchical positions. It was possible to verify, as well, that the ascension at the instructors career can be limited or directed, in other words, focused in areas where they already are a majority. Lastly, it's possible to say that the insertion of women instructors in management roles at federal universities in the state of Minas Gerais still haven't occurred in the same proportions as their insertion in the universities, in postgraduate courses and as instructors.

    2011-12-01

    Full Text Available Based on the concept that the trellising system affects not only sunlight interception and carbon assimilation, but also the fruitzone microclimate, which has a great impact on fruit composition and consequently on wine quality, the effect of two trellising systems - Vertical Shoot Position (VSP and modified Geneva Double Curtain (GDC - on wine and berry composition of Syrah grapes grown in João Pinheiro, Northeast region of Minas Gerais State, Brazil was investigated. The parameters such as pH, berry size and weight, and seeds total phenolic contents were not affected by the training system. The GDC system produced fruits with the highest Brix and lowest titratable acidity. Berries from the VSP system presented lower anthocyanin concentration than those from the GDC system. Similar results were found for the total phenolic content of the skin of grape berries from the VSP system. GDC wines were characterized by high anthocyanin content and red color, resulting in wines with high color intensity. These data suggest that in the tropical region of Minas Gerais state, with high temperature and high sunlight intensity, the trellising system, which protects bunches against excessive radiation, should be chosen.

The captures were carried out monthly between May 2001 and November 2002, with automatic light and Shannon traps. A total of 1444 sand flies were captured, 951 (76.5% with automatic light traps and 493 (23.5% with the Shannon trap. Thirteen species were captured, the most frequent being Nyssomyia whitmani (62.7%, Migonemyia migonei (21.4%, Pintomyia fischeri (6.9%, and Evandromyia lenti (3.6%. Species abundance was determined using the automatic light traps installed in the six environments. The most abundant species according to the standardized index of species abundance were Ny. whitmani (1.0 and Mg. migonei (0.82. In view of the dominance of these two species, known vectors of cutaneous leishmaniasis in other Brazilian areas, their participation in the transmission of the disease in this county is suggested. The diversity and evenness indexes in the domicile were the lowest due to the high frequency (83% of Ny. whitmani. The capture of Lutzomyia longipalpis, rarely recorded in the south-eastern and southern regions of Minas Gerais, is also noteworthy.

Although the species has appeared since 1992, until the present dayit has been in the list of species of the endangered Brazilian flora, the same behavior manifests monodominant behavior in some regions of Minas Gerais state, especially in the central Rio Doce area. Many studies have been conducted in order to describe and understand monodominated tropical forests. However, there is not so much information that clarifies the structure of forest fragments mono-dominated by Myracrodruon urundeuva. In this context, this study aimed to: a characterize parameters through floristic, phytosociological and parametric to the monodominance of Myracrodruon urundeuvain in the city of Tumiritinga, MG; b estimate the biomass and carbon stocks accumulated in these environments; c characterize the stage of regeneration of forest fragments mono-dominated by aroeira in Tumiritinga, in MG state based on the resolution 392 from CONAMA; d evaluate the correlation between canopy cover and stage of regeneration in fragmentes mono-dominated by aroeira. We randomly sampled 16 plots of400m² around the city of Tumiritinga, representing 6.400m² of “Aroeirais” that were sampled. The diversity analysis of the mono-dominated fragments that were studied showed Shannon-Weaver index equal to 0.25. Myracrodruon urundeuva represented 96% of the 678 sampled individuals, 96% of total basal area measured and 96% of the total volume stored in the inventory plots. In addition to the species Myracrodruon urundeuva, the floristic study showed only 10 other forest species representing even plant families. The estimates of aroeira biomass reached the average value of 81 m3.ha-1 of wood volume, 62.8 MgB.Ha-1, 35.2 MgC.ha-1 and 129.1 MgCO2.ha-1. The

Em torno de 50% dos estudantes eram do sexo feminino, mais da metade procedeu da capital do Estado, em Belo Horizonte, nasceu em família pequena com menos de três filhos, foi aprovada no primeiro vestibular e o pai cursou escola superior. A renda familiar situou-se entre 10 e 50 salários em 2/3 dos casos. Estes dados são compatíveis com a origem de classe média alta, embora em aproximadamente 12% a renda familiar foi inferior a 10 salários. A grande maioria estudou medicina por vocação ou altruísmo (80%, raramente por questões de mercado (<5%. Houve grande preferência pela medicina como profissão liberal (98%, mas em torno de 80% aceitaria o emprego público como alternativa. Quase todos (98% pretendiam fazer residência médica e se tornar especialistas, poucos (<20% indicaram entre estas as especialidades de área geral, como clínica médica, gineco-obstetrícia, pediatria e cirurgia. CONCLUSÃO: O estudo mostrou perfil socioeconômico relativamente elevado do estudante de medicina da UFMG e preferência pela prática especializada da medicina.

    Full Text Available Species of Chydoridae provide the main diversity of the Cladocera. These organisms have been the subject of many studies; some dealing with their role in energy flow in aquatic ecosystems, since they inhabit the littoral region of water bodies which undergo the first impacts from anthropic activities. The aim of this study is to increase knowledge about the life cycle of Coronatella rectangula (Sars, 1861, a species found in several water bodies in the state of Minas Gerais, Brazil. The life cycle was determined by the culture of parthenogenetic females under controlled conditions in the laboratory. Experimental cultures were maintained in growth chambers at a constant temperature of 23.6(±0.5ºC, through a 12 h light/12 h dark photoperiod. The organisms were fed on a suspension of Pseudokirchneriella subcapitata (Chlorophyceae (10(5 cells.mL-1, and 0.02 mL of a mixed suspension of yeast and fish ration added per organism in equal proportions (1:1. Fifty parthenogenetic females with eggs were isolated and maintained until they produced neonates. Thirty of these neonates that had less than 24 hours were put in polypropylene bottles of 50 mL and kept in a germination chamber. These organisms were observed daily to obtain the parameters of the life cycle. Biomass and secondary production were also calculated. The embryonic development time of the specimens of C. rectangula was 1.68(±0.13 days and the time to reach primipara, was 2.48(±0.45 days. The mean fecundity of C. rectangula was two eggs/female/brood and the total number of eggs produced by the female during its life cycle was 27.8 eggs. During the whole life cycle, specimens of C. rectangula had a maximum of 14 seedlings, with two instars in the juvenile stage. Total biomass for C. rectangula was 36.66 µgDW.m-3(9.83 for the juvenile stage and 26.82 µgDW.m-3 for adults, and secondary production was 12.10 µgDW.m-3.day-1(8.34 µgDW.m-3.day-1 for egg production and 3.76 µgDW.m-3.day-1 for

    Full Text Available A study was undertaken about T. sordida in the natural environment in two different regions of the state of Minas Gerais: Itapagipe (Triângulo, an area of cerrado modified by the formation of fields of pasture and agriculture, and Mato Verde (north an area of transition between caatinga and cerrado with profound deforestation in the last years due to the expansion of cotton cultivation. In both regions the principal ecotopes identified were hollow trees and the bark of live or dead trees, where the occurrence of a food source is not frequent. In this environment, the triatomines utilize various food sources; opposums appear to represent an important source of infection. In the north of Minas, a greater concentration of reservoirs and vectors was observed than in the Triángulo which could explain the higher level of infection of the triatomines in the north. Close attention to the process of domiciliation of T. sordida in the north of Minas is recommended where an extensive intervention by man in the natural environment has occurred and where a rise in the population of triatomines in the peridomestic environment has been observed in recent years.Foi realizado um estudo sobre o T. sordida em ambiente silvestre em duas diferentes regiões do estado de Minas Gerais: Itapagipe (Triângulo, área de cerrado modificado para formação de campos de pastagem e agricultura, e Mato Verde (norte uma área de transição entre a caatinga e o cerrado, profundamente desmatada nos últimos anos com a finalidade de expansão do cultivo de algodão. Em ambas as regiões, os principais ecotopos identificados corresponderam a buracos e cascas de árvores vivas ou mortas, onde a ocorrência de fontes de alimentação não é frequente. Neste ambiente, os triatomíneos utilizam-se de variadas fontes de alimentação; gambás parecem representar urna importante fonte de infecção. No norte de Minas, observou-se urna maior concentração de reservatórios e vetores

    Full Text Available Este trabalho analisa a formação de uma sensibilidade barroca em Minas Gerais a partir da orientação participativa e altamente emotiva das festas coloniais, cujo legado se mantem presente nas festas religiosas de muitas antigas cidades mineradoras do estado. Enfocando as celebrações da Semana Santa na cidade sul-mineira de Campanha, o texto mostra como este evento anual era organizado pela Irmandade do Santíssimo Sacramento, passando então às mãos de uma comissão local após a extinção da irmandade. Se até meados do século XIX, havia músicos semi-profissionais contratados para tocar e cantar nas celebrações, a música foi assumida progressivamente por grupos de amadores. Assim, a festa passou a ser entendida como uma produção local e a cada ano a população renova o seu orgulho campanhense, ao contemplar sua capacidade de produzir um evento tão 'maravilhoso'.This paper analyses the formation of a baroque sensibility in the State of Minas Gerais (Brazil that derives from the participatory and highly emotive orientation of the colonial festivals, the legacy of which is still present in many former mining towns in the region. By focusing upon the Holy Week celebrations in Campanha, a small town in southern Minas Gerais, the text shows how this annual event was organized by the Confraternity of the Holy Sacrament, but was then transferred to a local committee after the confraternity was made extinct. If up to the mid 19th century there were semi-professional musicians to perform for the celebrations, responsibility for the music was slowly taken over by amateur groups. In this way the festival came to be understood as a local affair, and each year the population renews its pride in itself for its capacity to stage such a 'marvelous' event.

  1. Radioecological impact of effluents from a nuclear facility being decommissioned in the Antas river hydro graphic basin in the state of Minas Gerais, Brazil. Radioecological impact of effluents in the Antas reservoir

    International Nuclear Information System (INIS)

    The Antas reservoir receives the treated effluents which come from acid drainage of uranium ore from the UTM-INB (Ore Treatment Unit - Brazilian Nuclear Industries), located in Caldas, Minas Gerais. This study was conducted in order to determine the possible environmental impact caused by discharge of the treated liquid effluent from the UTM into the Antas reservoir. Biological (ciliated protozoa and Peridinium sp. phytoflagellate) and physicochemical variables (manganese, zinc, sulfate, uranium, dissolved oxygen and temperature), trophic state and saprobity indexes were evaluated. Sampling in reservoir (Cab, P41, P14S, and P14F points) took place during the dry winter season (July 2006). Each day, samples were collected four times (6:00 am, 12:00 pm, 6:00 pm, and 12:00 am). Biological variables analyzed at the Antas reservoir classified it as an oligo trophic and beta-mesosaprobic environment. Chemical parameters indicate failures in the nuclear facility effluent treatment plant, showing that effluents outside of standard limits established by Brazilian current legislation for Class II water are being discharged at point P41. These results agree with biological analyses, since point P41 has the lowest diversity and biomass values for ciliated protozoa organisms, indicating possible environmental impacts on the ecosystem due to effluent discharge by this mining company.(author)

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

Assim, objetivou-se no presente estudo elaborar a modelagem da cobertura vegetal de vinte e quatro plantas de cobertura, em diversos sistemas de plantio e históricos de uso, com potencial para cultivo no Sul de Minas Gerais. Para avaliação da cobertura vegetal foram realizadas avaliações no campo utilizando uma régua de classificação da cobertura vegetal, sendo o delineamento experimental inteiramente casualizado, com três repetições, utilizado neste experimento. As plantas cultivadas sobre a palhada de feijãoirrigado apresentaram alto índice de cobertura do solo, o que pode estar relacionado à maior disponibilidade de nutrientes deixado por esta cultura na palhada e a maior reserva de água no solo, promovido pela irrigação do feijão. O milheto cultivado em nível e sobre a palhada de milheto e feijão-de-porco apresentou o menor índice de cobertura entre as plantas testadas. Na região sul de Minas Gerais os padrões de chuvas ocorrem em maior quantidade nos períodos de outubro a março, com elevação em dezembro e janeiro. Neste período o solo deve estar protegido do impacto da gota de chuva, pois o risco de erosão hídrica é maior. Assim, a utilização das plantas de cobertura é de grande importância, pois estas protegem o solo do impacto direto dasgotas de chuvas e diminuem os picos de temperatura do solo, sendo que estas devem ser cultivadas, preferencialmente, sobre a palhada de feijão.The ground cover is the most important factor relative to control erosion.

    Monazite-(Ce) is found in granitic pegmatites in the Santa Maria de Itabira pegmatite district (Minas Gerais, Brazil). During the magmatic stage, monazite-(Ce) seems to have had higher contents of cheralite and buttonite in the solid solution. The Th content in primary monazite-(Ce) is high and characteristic for each pegmatite body. During the late stage (albitisation), the mean LREE content in the altered zone is slightly higher and Th content is very low. The accessory mineral assemblages changed; buttonite and cheralite crystallize together with Th-poor and La-rich monazite-(Ce) at the border of altered crystals.

Tais políticas educacionais enquadram-se na modalidade de regulação educativa denominada obrigação de resultados, que compreende um conjunto de intervenções caracterizadas como medidas de controle com o propósito de obter maior eficácia escolar. O levantamento documental e a análise dos dados empíricos indicaram que as medidas empreendidas pelo governo concentram sobre os professores a responsabilização pelo êxito ou pelo fracasso dos alunos nos sistemas de avaliação em larga escala e nas avaliações regulares das escolas. A avaliação de desempenho dos professores e a avaliação institucional das escolas são vinculadas aos resultados escolares, sendo definidos centralmente, sem a participação dos professores, os percentuais de alunos que devem ser promovidos e os índices de proficiência a serem alcançados. Em tal contexto de cobrança de resultados, não são levadas em consideração as condições de trabalho docente na rede estadual de ensino em Minas Gerais.

    Full Text Available As exigências do mercado por cafés de melhor qualidade estão sendo responsáveis pela difusão e adoção de novas tecnologias de produção e preparo de café. Entre os cafés especiais, o café orgânico é um dos que mais vem se destacando neste segmento. Desta forma, objetivou-se nesse trabalho, a avaliação das características agronômicas de lavouras cafeeiras (Coffea arabica L. sob o sistema orgânico de produção, localizadas no Município de Poço Fundo, sul de Minas Gerais. Foram caracterizadas em 21 lavouras cafeeiras orgânicas as cultivares utilizadas, a população cafeeira, o tipo de colheita e secagem adotadas, a produtividade e qualidade do café, a fertilidade do solo e o estado nutricional do cafeeiro. Através dos resultados obtidos, concluiu-se que os cafeeiros conduzidos sob o sistema orgânico de produção apresentam potencial para produzirem cafés de boa qualidade. Em relação à fertilidade do solo, os baixos valores de pH e o desequilíbrio das relações entre K, Ca e Mg observados na maioria dessas lavouras, sugerem que esses fatores podem afetar o crescimento, o desenvolvimento e a produção dos cafeeiros submetidos ao manejo orgânico do sul de Minas Gerais.The market demands for coffee of better quality are being responsible for diffusion and adoption of new production technologies and coffee preparation. Among the special coffee, the organic coffee is one of the most important in this group.

    Full Text Available Entre as doenças invasivas causadas pelo Haemophilus influenzae tipo b (Hib, destacam-se, pela freqüência e gravidade, as pneumonias e as meningites. No período de 1993 a 1997, foram notificados, em Minas Gerais, 720 casos de meningites por Hib, sendo a causa mais freqüente de meningite bacteriana em menores de um ano e a segunda causa no total de meningites. Entretanto, estimou-se uma ocorrência total de 1.160 casos considerando as meningites bacterianas não especificadas. O total de casos estimados de doença invasiva por Hib parece justificar a recente inclusão da vacina no esquema básico de imunizações. O alto custo da vacina reforça a necessidade de melhorar a vigilância epidemiológica da meningite, que constitui uma das fragilidades das ações de controle desta doença.Among Haemophilus influenzae type b (Hib invasive diseases, pneumonia and meningitis are the most relevant in public health due to their frequency and severity. From 1993 to 1997, there were 720 cases of Hib meningitis in Minas Gerais State, Brazil, representing the most frequent cause of bacterial meningitis in infants (< 1 year and the second most frequent among all causes of meningitis. The total estimated cases of invasive Hib diseases thus appear to justify the recent inclusion of the vaccine in the basic immunization protocol. The vaccine's high cost reinforces the need for more precise monitoring of the etiological diagnosis of meningitis cases, representing one of the weaknesses in the prevailing epidemiological surveillance system.

Para isso, é importante que as estratégias do setor financeiro procurem viabilizar a ocorrência de sobras, pois esta é uma indicação de que a empresa consegue pagar a seus credores, atender os associados e proporcionar retorno financeiro para a cooperativa. Nesse sentido, buscou-se avaliar a influência dos indicadores financeiros na ocorrência de sobras e determinar qual a estratégia adotada pelas cooperativas de cafeicultores do Estado de Minas Gerais, com base na estrutura financeira, utilizando o modelo Logit. Constatou-se que as sobras apresentadas pelas cooperativas foram explicadas pelo giro dos ativos e pela rentabilidade sobre vendas, e suas estratégias concentram-se na administração de vendas.Coffee producer cooperatives need to have a capital structure coherent with their associates' objectives and administered to maintain the organization’s competitiveness. For this, it is important that the cooperative’s financial section’s strategies lead to the creation of a financial surplus to pay creditors, assist the associates, and provide the cooperative a financial return. Using the Logit model, our study evaluates both the financial strategies employed by coffee producer cooperatives in the state of Minas Gerais to maximize surpluses and the influence of different financial indicators on the occurrence or non-occurrence of these surpluses. It was verified that the analyzed cooperatives’ business strategies concentrate on the management of sales and that the occurrence or non-occurrence of surpluses was explained by asset turnover and the profitability of sales.

    International Nuclear Information System (INIS)

    The Iron Quadrangle, located in the Brazilian state of Minas Gerais, is considered one of the richest mineral-bearing region in the world. It is well known for the occurrence of iron and gold ores. A great number of active and ancient gold mines can be found in this region. The gold ore is rich in arsenic with the As/Au ratios ranging from 300 to 3000. In the past companies produced As-oxide as a byproduct in Nova Lima and Passagem de Mariana regions. Dressing materials were usually stored along the rivers or simply thrown in the drainage (e.g. Carmo river in Passagem de Mariana). Nowadays, big dams have been built to store the tailings and the effluents are being treated according to environmental regulations. Ma et al. and Francesconi et al. have demonstrated that the fern species, Pteris vittata and Pityrogramma calomelanos are arsenic hyperaccumulate plants and recommend them for use in the remediation of arsenic-contaminated soils. These species were suggested for phytoremediation due to their high bioaccumulation factors, short life cycle, high propagation rates, wide distribution, large shoot mass and their ability to tolerate high arsenic concentrations in soils. Phytoremediation, an emerging plant-based technology for the removal of toxic elements from the soil and water has been receiving renewed attention. The aim of this work was to evaluate the uptake of arsenic by the ferns Pteris vittata and Pityrogramma calomelanos collected in an area of the Iron Quadrangle that might be suffering influence from contaminated arsenic waste from old gold mines. These ferns are commonly found in this region. Fern samples and the soil within the root mass were collected in February and March 2003. The samples (Pteris vittata) were divided into leaves and rhizoids. The leaves and rhizoids were washed thoroughly with tap water, rinsed with deionized water and sliced in small pieces.

    Full Text Available Cytogenetic studies were performed on two sympatric species of Characidium, C. gomesi and C. cf. zebra, from the Grande River basin, Minas Gerais State, Brazil. Although both species had a chromosome number of 50 with a karyotype exclusively consisting of meta- and submetacentric chromosomes, interspecific diversity was detected concerning the size of the two first chromosome pairs of the karyotypes. Active nucleolus organizer regions (NORs were located at the terminal position on the long arm of the 17th pair of C. gomesi and at subterminal position on the long arm of the 23rd pair of C. cf. zebra. For both species the fluorochrome CMA3 stained only the NOR-bearing pair of chromosomes. The heterochromatin pattern also showed some differentiation between these species restricted to the centromeric or pericentromeric region of C. cf. zebra and practically absent in C. gomesi. These data are discussed concerning chromosome diversification in this fish group.

    International Nuclear Information System (INIS)

    The present report refers to the Rio Espera sheet (SF.23.X-B-IV) systematic geological mapping, on the 1:100.000 scale. The sheet, which covers Zona da Mata region, includes the Southeastern bord of Minas Gerais Metallurgic Zone, SE of Quadrilatero Ferrifero, in the Sao Francisco craton bord, and Mantiqueira province. Since only one doubtful 2,5 thousand million year - Rb/Sr isochron was obtained in the sheet, Archacan and Proterozoic ages have been attributed to the metamorphic rocks by comparison to other ones elsewhere. An analysis of the crustal evolution pattern based on gravimetric survey data, aeromagnetometry and available geochronological data is given in the 6. Chapter, Part II of the text. Major elements oxides and rare-earths were analysed to establish parameters for the rocks environment elucidation. The geochemical survey was carried out with base on pan concentrated and stream sediments distributed throughout the sheet. (author)

  14. Polycyclic migmatites from southern of Minas Gerais state and adjacent parts: structural/petrographic characterization and geochronological data

    International Nuclear Information System (INIS)

    The geology of the southern part of the State of Minas Gerais and adjacent parts of the State of Sao Paulo (SE Brazil) is built up by gray gneisses (Barbacena and Amparo Complexes), pink gneisses (Pinhal Complex) and granulites (Guaxupe Complex) areas, the oldest of them of Archaean ages. Structural, petrographic, geochronological and geologic data indicate that in fact each of those complexes is the result of a long evolution including successive phases of deformation, anatexis and intrusions. The extensive migmatization of the Archaean rocks during the Lower and Upper Proterozoic combined with the intrusion of huge granitoid bodies suggest that the considered region has been involved in successively continental approaches by subduction/collision processes.

All studied herds showed C. fetus infected animals and, of 157 animals, 40 (25.5% were positive in DFAT: 7 (26.9% from herds with natural breeding and 33 (25.1% from herds with both artificial insemination and natural breeding after the second-to-third insemination. The high frequency of BGC found in this study shows that this disease is present among herds which have reproductive problems and the use of natural breeding after the second-to-third unsuccessful insemination could be a risk factor for the disease.

    Full Text Available The adolescence is a human development time characterized by biopsychosocial changes, influenced by personal life experiences. In this context pregnancy along adolescence has been regarded as a relevant social issue due to the high prevalence in this age group. This study aims to describe biopsychosocial characteristics of adolescent mothers in a school hospital (SH of a public university in Minas Gerais, Brazil. This is a cross-sectional descriptive study with 40 adolescent mothers in this hospital. Data were collected through a form and analyzed using descriptive statistics. The data in this study were similar to findings in studies conducted in other urban centers especially as regards the participants’ average age and the precarious economic condition of their families and school performance. The data analysis has highlighted the need to understand teenage pregnancy as an experience with different factors as biological, psychological, economic and social development.

    Full Text Available In a survey realized on the sylvatic and peridomestic environment at Bambuí county, Minas Gerais State, 44 (37.9% out of 116 opossums (Didelphis albiventris captured were found to be naturally infected with Trypanosoma cruzi. One handred and forty three parasite samples were obtanied from 43 infected opossums using simultaneously hemoculture, xenodiagnosis (Triatoma infestans, Panstrongylus megistus and Rhodnius neglectus and examination of anal glands contents. The parasite samples were characterized according to six isoenzyme patterns. All samples, independently of the method of isolation, presented an isoenzyme pattern similar to the standard T. cruzi Z1, showing that either xenodiagnosis or hemoculture can used without selecting parasite subpopulation from naturally infected opossums. Preveous isoenzyme patterns reported for human T.cruzi isolates from same region were completely different. This isoenzyme dissimilarity between sylvatic and domiciliar environments suggests the existence of two independent T. cruzi transmission cycles in Bambuí. The epidemiological implicatinos of these results are discussed.

  18. Hydrothermal alteration of monazite-(Ce) from the Santa Maria de Itabira pegmatite district (Minas Gerais, Brazil)

    International Nuclear Information System (INIS)

    Monazite-(Ce) is found in granitic pegmatites in the Santa Maria de Itabira pegmatite district (Minas Gerais, Brazil). During the magmatic stage, monazite-(Ce) seems to have had higher contents of cheralite and buttonite in the solid solution. The Th content in primary monazite-(Ce) is high and characteristic for each pegmatite body. During the late stage (albitisation), the mean LREE content in the altered zone is slightly higher and Th content is very low. The accessory mineral assemblages changed; buttonite and cheralite crystallize together with Th-poor and La-rich monazite-(Ce) at the border of altered crystals. Nd/Sm and U/Pb ratios also changed during the hydrothermal stage. (authors)

    Science.gov (United States)

    Fischer, Georg

    2014-01-01

    This article deals with the "discovery" of Brazilian iron ore from two perspectives. The first examines the increasing emphasis of the geosciences and their practical application and global reach since the second half of the nineteenth century. While in Brazil economic geology was integrated step by step into state institutions, at the global level it experienced its moment of triumph with the 11th International Geological Congress in 1910. The second deals with a specific social network with a decisive role in the race for Brazilian iron ore: with transnational experts juggling between the logic of the market and that of the academy. The article reveals the importance of local negotiations in the incorporation of the subsoil of Minas Gerais into the global space of mining. PMID:24554136

    Full Text Available The objective of the present study was to evaluate parasitemia and packed cell volume patterns of dogs experimentally inoculated with two isolates of Babesia canis: one from Belo Horizonte (BH and the other from Lavras (Lv, Minas Gerais State, Brazil. Both isolates showed similar patterns, with the peak of parasitemia occurring three days post-infection. From the fourth day, parasitemia was detected in low levels (0.01% with small periodical increases. The packed cell volume decreased after the parasitemia beginning, with oscillations during the experimental period. All dogs remained apparently normal, except one, which had been inoculated with the BH isolate and presented classical clinical signs of babesiosis (weakness, anemia, hemoglobinuria and depression. The results suggest that the studied isolates have low pathogenicity, and point to the need for further studies aiming to characterize the subspecies of Brazilian isolates.

    Full Text Available Psychological tests are widely used in Personnel Selection processes in Brazil. However, in many cases, studies that provide psychometric parameters are necessary to certify their validity and reliability to the organizational area. This research aimed to identify which psychological tests organizational psychologists are mostly using after the analysis realized by the Federal Council of Brazil in 2003. Nine companies of Minas Gerais participated of this study and their respective psychologists answered a structured questionnaire that was elaborated according to the goals of the research. The results revealed that personality tests have been being applied in a bigger proportion than intelligence tests. The results also revealed that 33% of the professionals have being using instruments considered inappropriate after the Council´s analysis. Implications of the results to research and practical matters are being discussed.

    Full Text Available The main objective of this cross-sectional study was to analyze factors associated with alcohol consumption among adult women living in Belo Horizonte, Minas Gerais State, Brazil, in 2011. Data for Belo Horizonte were obtained from the VIGITEL system (Telephone-Based Surveillance of Risk and Protective Factors for Chronic Diseases. Alcohol use was defined as self-reported intake of at least one dose in the previous 30 days; alcohol abuse was defined as four or more doses on at least one occasion during the same period. Polytomous logistic regression was used to evaluate factors associated with alcohol use and abuse. Alcohol use was more prevalent among women 25 to 34 years of age. Alcohol abuse was associated with age, schooling, health status, and smoking. The results suggest the need for policies to prevent alcohol abuse among women, especially targeting those who are younger, single, smokers, and with more education.

  4. Workplace and occupational health: The first metal evaluation using nuclear and analytical techniques in the State of Minas Gerais, Brazil

    International Nuclear Information System (INIS)

    Belo Horizonte, the capital of the State of Minas Gerais and its neighbourhood are the second industrial center of Brazil, concentrating many industries in several areas mainly metal refining and transformation. There are no registers about the level of metal concentration in the environmental air in the industry, nor even of the level of workers' contamination. The overall objective of this Project is to make a survey of the exposures to metals related to occupational diseases in galvanizing industry, which is responsible for the majority of occurrences of occupational diseases. The survey will be accomplished using as bio-indicators hair, nails, blood, urine, and individual air filters. These matrixes will indicate the incorporation of metals and the exposure level. The analytical techniques that will be applied are the neutron activation joined to related non nuclear analytical techniques, such as atomic absorption. (author)

    Full Text Available In order to ascertain the existence of socioeconomic structures significantly different from each other, this study made use of statistical techniques that allowed, based on socioeconomic conditions, public finance and economic activity characterize the municipalities of Minas Gerais and investigate the inter-regional disparities within the state. Through the theoretical framework that revels the themes Regional Disparities and Intervention of the State and New State Planning and Promotion of Socioeconomic Development, there are the relations between the state¿s role in the context of federalism and socioeconomic development of the municipalities, in addition to revel the main theoretical sources that deal with the emergence of disparities and their motivators. So the results confirmed the occurrence of significant differences between them and as explained in the theoretical framework also confirmed that the Minas Gerais's territory is marked by differences in economic, social and public finances, as demonstrated by the existence of two groups of municipalities. It should be noted, moreover, a spatial concentration of the municipalities, whose socioeconomic conditions, public finance and economic activity are better than the others. Among the main considerations can be pointed out the existence of a relationship between the analyzed variables, since those municipalities that have a greater economic activity have better socioeconomic conditions and public finances, proving the importance of the market in the provision of the property and with the State be a catalyst for socioeconomic development but, on the other hand, contributes to the emergence of disparities, in theory, should be combated by the State.

    The thorium-rare-earth element deposit at Morro do Ferro is of supergene origin and was formed under lateritic weathering conditions. The ore body forms shallow NW-SE elongated argillaceous lenses that extend from the top of the hill downwards along its south-eastern slope. The deposit is capped by a stockwork of magnetite veins which have protected the underlying, highly argillaceous host rock from excessive erosion. The surrounding country rocks comprise a sequence of subvolcanic phonolite intrusions that have been strongly altered by hydrothermal and supergene processes. From petrological, mineralogical and geochemical studies and mass balance calculations, it is inferred that the highly weathered host rock was originally carbonatic in composition and was initially enhanced in thorium and rare-earth elements compared to the surrounding silicate rocks. Intrusion of the carbonatite produced fenitic alteration of the surrounding phonolites, consisting of an early potassic alteration followed by a vein-type Th-REE mineralization with associated fluorite, carbonate, pyrite and zircon. Subsequent lateritic weathering has completely destroyed the carbonatite, forming a residual supergene enrichment of Th and REEs. Initial weathering of the carbonatite leading to solutions enriched in carbonate and phosphate may have appreciably restricted the dissolution of the primary Th-REE phases. Strongly oxidic weathering has resulted in a fractionation between cerium and the other light rare-earth elements. Ce{sup 3+} is oxidized to Ce{sup 4+} and retained together with thorium by secondary mineral formation and adsorption on poorly crystalline iron- and aluminium-hydroxides. In contrast, the trivalent LREEs are retained to a lesser degree and are thus more available for secondary mineral formation and adsorption at greater depths down the weathering column.

    The Ore Treatment Unit (OTU) is located at the source of three rivers: Ribeirao das Antas, Ribeirao do Soberbo and Corrego da Consulta. Each interface of installation with the environment, at the tree rivers, has been monitored for the release of radionuclides. At Ribeirao das Antas a weekly sample collection was made at point 014. At Ribeirao Soberbo there was a weekly sample collection at point 025, and at Corrego da Consulta a monthly collection was carried out at point 076. This work analyses the average annual releases of uranium from the historical series started in 1999 and ended in 2011. Points 014 and 025 showed average release of 0.12 Bq L{sup -1}. Point 076 showed somewhat higher average release, 1.27 Bq L{sup -1}. An Analysis Of Variance test (ANOVA) has been carried out to verify the existence of different means between these collecting points. The averages were considered statistically different. As a complementary analysis, the Student's t test was performed between the averages at considered points. Between points 014 and 025, the averages were considered identical. Between points 014 and 076, the average release at point 076 was considered higher than that at point 014. The same behavior was observed between points 025 and 076. The releases at point 076 were considered higher than those at point 025. Thus it can be concluded that releases at points 014 and 025 are identical and both are lower than releases at point 076.

During gonadal maturation, the females showed a low hepatosomatic index, suggesting that hepatic substances are possibly transferred from liver to ovaries. During the reproductive period, this fish had lower stomach repletion and coelomic fat indexes, indicating that the species eat less and consume more fat reserves. The weight of the ovaries influenced positively the condition factor (K1, since the lowest K2 values (without the gonads weight, were obtained during maturation, confirming the influence of the weight of the ovaries upon the physiological condition of the females.O 'saguiru' Steindachnerina insculpta, peixe teleósteo detritívoro que ocorre no reservatório de Furnas, bacia do alto Paraná, Minas Gerais, apresenta período reprodutivo prolongado que se estende de setembro a março, com desova parcelada. Durante a maturação gonadal, fêmeas apresentaram baixos valores do índice hepatossomático, sugerindo que possivelmente, substâncias hepáticas são transferidas do fígado para os ovários. Durante o período reprodutivo, os peixes desta espécie apresentam índices de repleção estomacal e de gordura celômica baixos, indicando diminuição da atividade alimentar e consumo de reservas. O peso dos ovários influencia positivamente o fator de condição (K1, uma vez que os mais baixos valores de K2 (sem o peso das gônadas foram obtidos durante a maturação, confirmando a influência do peso dos ovários na condição fisiológica das fêmeas.

    Aquamarines from three pegmatites located the vicinities of the Pedra Azul city, Minas Gerais state, were investigated in terms of chemical composition, physical properties and Moessbauer spectroscopy. The small lenticular pegmatite bodies are usually less than 5 m wide and exhibit a conspicuous mineralogical and textural zoning. The last thermal event in these pegmatites, determined by K-Ar method in muscovite, is of Neo proterozoic age, coincident with the late stages of the Brasiliano tectono- metamorphic cycle. Chemical analyses showed that sodium is the alkali with higher contents in the aquamarines, thus enabling their classification as sodic beryls. In zoned samples there is an increase of Fe as well as Mn from center to border, while no systematic variation could be detected for other elements. The specific gravity of 2.72 to 2.80 g/cm{sup 3} is higher than the values determined for samples from other pegmatites of Minas Gerais. The refraction indices are ne=1.569 - 1.579 and NW= 1.573 - 1.581 and the birefringence varies from 0.002 to 0.008. The refraction indices increase with the Be O content. The color of aquamarines varies from medium to light blue, sometimes greenish blue. Moessbauer spectra obtained at room temperature and at 80 K show that Fe{sup 2+} is the main chromophore-ion and suggest that the iron is present in octahedral sites as well as in the structural channels. Moessbauer spectra also indicate that the incorporation of Fe{sup 3+} may cause a shift from deep blue to light blue colors. Based on their aquamarine composition the pegmatites were classified as barren, poor in rare alkalis (Li, Rb, Cs) and therefore little differentiated. The relatively simple mineralogy and the lack of lithium minerals such as lepidolite and spodumene confirm this classification. Thus, the composition of beryl can be used as a tracer for the prospection of pegmatites with different degrees of differentiation and consequently with different types of

A total of 377 diarrheal fecal samples were obtained between January 2007 and August 2011 from inpatient and outpatient children of age ranging from 0 to 12 years. All samples were previously tested for rotavirus, norovirus, and astrovirus, and 314 of 377 were negative. The viral DNA was extracted, amplified using the polymerase chain reaction and the HAdV-positive samples were sequenced and phylogenetically analyzed. Statistical analyses were performed using the Chi-square test (p < 0.05, considering two conditions: the total of samples tested (377 and the total of negative samples for the remaining viruses tested (314. The overall prevalence of HAdV was 12.47% (47/377; and in 76.60% (36/47 of the positive samples, this virus was the only infectious agent detected. The phylogenetic analysis of partial sequences of 32 positive samples revealed that they all clustered with the HAdV-F type 41.

The project takes sustainable development as its guiding principle, and relies on the joint implementation of an innovative technical design, a governance model involving public participation and subsidiarity, and an economic structure combining financial viability and social equity. Designed at a consistent geographical and hydrological scale, it includes the creation of a regional subsidiary of the existing state water company as a keystone element. The institutional organisation also relies on the creation of a public board consisting of the 92 municipalities of the project region and of the State of Minas Gerais. This board will be in charge of the system's governance. This paper presents the first step of the project (2006, consisting of a feasibility study and the implementation of 9 pilot sub-projects. During the feasibility study, the supply, demand and capacity to pay for water services were defined, existing infrastructure appraised, the necessary amount of investment assessed and an innovative operational model and a sustainable management system, including civil

    Full Text Available Abstract Aims: Vereda wetlands are among the most important aquatic habitats in Brazilian savannah (Cerrado because of their association with river springs and its relevancy for biodiversity conservation. This study aimed to determine and compare the biodiversity of zooplankton in vereda lakes, differentiated by the presence or absence of aquatic macrophytes at an environmental reserve in Uberlândia, Minas Geais, Southeastern Brazil. Zooplanctonic abundance patterns and their relation with environmental parameters were also discussed and presented through multivariate statistics. Methods Twelve samples were taken at water surface, at 15-day intervals in 2006. It was observed a total richness of 75 species, including 12 genera, 29 species and one sub-species as new records for Minas Gerais State. Results Rotifers were the predominant group and Lecanidae was the most diverse family. Among cladocerans, Chydoridae showed the greatest richness and Bosminidae the highest abundance. Few adult copepods were sampled in this study, but nauplii were very frequent. Cyclopidae was the most common family among copepods and there was no record of Calanoida. Conclusions The difference in composition among the studied lakes was remarkable. The lake with macrophytes showed the greatest richness but the lowest density, and the opposite situation occurred in the other lake. This can be explained by the fact that aquatic macrophytes, as primary producers, exert a bottom-up effect on zooplankton community, sustaining a high local diversity in contrast with a low numeric abundance of these microorganisms. Therefore, this pattern may have been created by the surround heterogeneity and, at the same time, by the reduction of available minerals of the system caused by macrophyte matter fixation. Many studies on zooplankton need to be developed in palm swamp communities in order to better comprehend the biological diversity and the energy balance in different habitats for

    Full Text Available Objetivou-se, neste estudo, avaliar a qualidade microbiológica de leite pasteurizado, queijo Minas Frescal (QMF e carne moída bovina. Um total de 74 amostras, coletadas nos estabelecimentos comerciais dos municípios de Barbacena, Juiz de Fora, Muriaé, Rio Pomba e Ubá, foram submetidas às análises de coliformes totais, coliformes termotolerantes, Escherichia coli e Salmonella sp. Além disso, as amostras de QMF foram submetidas às análises de estafilococos coagulase positiva (ECP e Listeria monocytogenes. Todas as amostras apresentaram contaminação por coliformes totais, e 81,6 % das amostras apresentaram valores acima do preconizado pela RDC n°12 da ANVISA para coliformes termotolerantes, além de alta incidência de E. coli. Dentre as amostras de QMF, 75% estavam em desacordo com a legislação para ECP. Todas as amostras apresentaram ausência de Salmonella sp. e L. monocytogenes. Os resultados mostraram que esses alimentos de origem animal comercializados na região de Minas Gerais não estão aptos para o consumo humano devido à baixa qualidade microbiológica. Existe, portanto, a necessidade de adoção de boas práticas de fabricação, além de sanitização eficiente para minimizar os riscos de transmissão de patógenos de origem alimentar por meio destes alimentos.

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

    Archaeological rupestrian arts of the Planalto Tradition are of relatively widespread occurrence all over the land area of the state of Minas Gerais (MG), Brazil. They are typically composed by monochromic zoomorphic figures, especially of cervids, mainly in red or orange color. A fragment of a rock wall containing an archaeological painting was collected at the Itanguá site, in the municipality of Senador Modestino Gonçalves (geographical coordinates, 17° 56' 51″ S 43° 13' 22″ W), MG. The rock piece was covered with an archaeological painting with pigments of two different hues of red. The X-ray fluorescence (XRF) analysis revealed only a slight difference in Fe and P content for the two different color zones. The pigment materials on this small fragment of rock were analyzed by X-ray diffraction on the conventional incidence mode (XRD) and on grazing incidence X-ray mode (GIXRD), scanning electron microscopy with energy dispersive x-ray detector (SEM/EDS) and conversion electron Mössbauer spectroscopy (CEMS) at room temperature. Results indicated the occurrence of mainly hematite but also of diopside in the pigment. CEMS at RT reveal the presence of hematite and (super)paramagnetic ferric components. In order to confirm these results a small amount of powder from the painting pigments was also analyzed by transmission Mössbauer spectroscopy at 20 K.

    Stigmaeidae are very important predators of mite and insect pests on several crops in Brazil. It is considered the second most important family of predatory mites in citrus orchards in Brazil. However, their identification, especially that of the members of the genus Agistemus, is rather difficult based only on morphology. Hence, this study describes the use of random amplified polymorphic DNA (RAPD-PCR) markers to determine the genetic similarity of an Agistemus pallinii Matioli et al population found in 2004 in a citrus orchard in Vicosa, Minas Gerais State, Brazil, preying on Panonychus citri (McGregor). Amplifications were performed with 12 random primers (OPAA8, OPAA19, OPAB1, OPAB5, OPAB18, OPAC9, OPAC17, OPAC19, OPAD10, OPAE9, OPAE12 and OPAE17), which generated 119 bands, with 53.8% polymorphism. The coefficients of genetic similarity among the individuals ranged from 0.68 to 0.99, indicating a high genetic similarity among them. The 3D projection analysis clustered the majority of individuals confirming their high similarity. Though individuals of A. pallinii are minute ({+-} 360 {mu}m long), the PCR-RAPD technique can still be used for their identification, complementing morphological analyses or for comparison of populations collected in different geographic regions. This is the fi rst molecular study carried out with stigmaeid mites. (author)

    Full Text Available INTRODUCTION: Children are an important high-risk group for helminth and protozoa infections. Daycare centers are environments where children have proven to be more susceptible to acquiring intestinal parasites. Thus, the purpose of this study was to verify the prevalence of intestinal parasites in children who attended the two daycare centers maintained by the local government of Uberlândia, State of Minas Gerais, Brazil. METHODS: Fecal samples were collected from 133 children (73 children at the Public Preschool for Early Childhood Education, PPECE A, and 60 at the PPECE B following identification according to sex and age and agreement to participate by parents or guardians who signed the free, informed consent form. The samples were examined by the Lutz method. RESULTS: Coproparasitological tests performed on 133 children showed that 29.3% of them were parasitized for enteroparasites or commensals, 6.7% of the children presented polyparasitism. Among the protozoa, Giardia lamblia were the most prevalent and Hymenolepis nana were the most frequent among the helminths. CONCLUSIONS: Thus, analysis of the results showed that intestinal parasites still represent a public health problem, especially among children and in areas where the socioeconomic and educational conditions are less favorable.

    Full Text Available Despite the importance of human taeniasis/bovine cysticercosis for public and animal health and the economy, its actual epidemiological status in Brazil is not well-studied. We sought to assess the epidemiological profile of this zoonosis in the rural area of Viçosa County, Minas Gerais, Brazil. The prevalence of bovine cysticercosis was 0.42%, whereas no case of human taeniasis was diagnosed. Factors favoring the persistence of zoonosis were identified. These included the supply of untreated water to animals, animals raised for slaughter without sanitary supervision, poor mechanization of raising techniques, and the use of untreated water for human consumption. Bovine meat for human consumption acquired in the city or from the farm itself was characterized as a risk factor for bovine cysticercosis (Odds Ratio (OR =16.77; p<0.05. Nevertheless, the families on the investigated farms did apply several appropriate measures to control this disease, such as the virtual lack of open sewers and the consumption of well-cooked meat. The presence of bovine cysticercosis cases, and the factors favoring its persistence, point to the need for constant epidemiological and sanitary surveillance in this county.

    Full Text Available This paper reports 40 cases of human rabies studied at the Carlos Chagas Hospital of UFMC, State of Minas Gerais, Brazil, from 1963 through 1976. From the epidemioiogical point of view it is concluded that the magnitude of the problem of human rabies in underdeveioped countries remains quite unknown. Speciai emphasis is given to the lack of apropriate knowledge of the recommended preventive measures, and to the influence of health education and socio-economic-cultural structure of the communities. The classic clinical picture of human rabies is briefiy described, particular attention being drawn to psychopathologic features of rabies encephalomyeiitis. it is pointed out that in some cases the mental symptoms may predominate from the onset of the illness, adding difficuity to the diagnosis. According to the Authors, human rabies must be differentiated from several psychopathologic syndromes and also from encephalomyelitis due to other central nervous system infections. It is discussed whether the fataiistic concept of human rabies would be somehow contributing to delay a better understanding of the natural history of the disease.

    Full Text Available This paper presents the main ideas discussed in the round-table "Social and Educacional Aspects of Schistosomiasis Control", during the VII International Symposium of Schistosomiais. Considering the perspectives of schistosomiasis control in Brazil, it is described the example of the State of Minas Gerais , where the disease has been registered for more than seven decades. The importance of an extensive evaluation is now more important, considering the recent change in the Brazilian health system, since the Federal responsibility for the tropical diseases control programs have been replaced by the municipalities coordination. In this way, it is urgent to develop effective alternatives to assist the municipal staffs in the control task. In the specific case of health education, one observes a wide gap between the planned objectives and what is in fact carried out. Instant objectives and the utilization of traditional techniques prevail, which do not take into account the active participation of the population involved. Based on the authors' experience in the scientific and health education, the paper analyzes: (1 some data from a case study in the metropolitan region of Belo Horizonte, which presents the social representation and perception of schistosomiasis by the population; (2 an analysis of 35 different informative and educative materials used in Brazil since the sixties, and (3 some recommendations resulted from the studies that were carried out.

    Full Text Available This study aimed at quantifying carbon (C and biomass stocks in shoot portion, leaf litter, roots and soil within a fragment of dense savanna 'cerradão', 158.5 ha in area, located in Minas Gerais state. Measures were quantified using dendrometric parameters obtained during the forest inventory and collection of leaf litter, root and soil samples. Furrows were dug in the soil each 100 cm long, 50 cm wide and 100 cm deep in order to collect root samples at depths of 0-30 cm, 30-50 cm and 50-100 cm, and soil samples from the layers 0-10 cm, 10-20 cm, 20-40 cm, 40-60 cm and 60-100 cm, as well as any leaf litter from the surrounding surface. Analyses were performed in the Organic Matter Study Laboratory (DCS/UFLA to determine C contents in the above matrices, using an Elementar analyzer model Vario TOC Cube. Higher C contents and stocks and lower density were noted in topmost soil layers. In cerradão, shoot portion was found to be the matrix contributing the most to biomass production, followed by roots and leaf litter. Carbon stock in the fragment was 139.7 Mg ha-1. Soil was the matrix contributing the most to stocked C (64.8%, followed by the shoot portion (26.3%, roots (5.2% and leaf litter (3.7%.

    Full Text Available Vampire bats are important agents in the field and currently regarded as the main reservoir in Latin America in the transmission of rabies of herbivores, thus, these animals are monitored by researchers and animal health protection services and suffer from populational control to minimize the impact of the occurrence of cases of rabies in domestic animals. Rabies is a zoonosis of 100% lethality. The presence of haematofagous flies have been observed in these animals. There of is to highlight the importance of these agents that are restricted parasites of bats and could be responsible for transmission of the rabies virus between them. It is also worth emphasizing the importance of assessing the distribution of these parasites of bats according to the climatic conditions of a given site, because these elements are essential to limit the distribution of these parasites. The presence of parasites in animals presents itself as an important element for understanding the mechanisms that are configured in the control of population of a given agent. The present study aimed to record the occurrence of flies in vampire bats in the Forest of Minas Gerais State.

    The epidemiology of chicken lice species such as Menacanthus stramineus, M. cornutus and M. pallidulus were studied during an observational, analytical and sectional survey, to determine predisposing factors for their occurrence in laying hen farms in the State of Minas Gerais, Brazil. A total of 431 houses on 43 farms were visited in 2012. M. cornutus, M. stramineus and M. pallidulus occurred in 20.9%, 11.6% and 11.6% of farms, respectively. The frequencies of occurrence of M. cornutus, M. stramineus and M.pallidulus in poultry houses were 10.4%, 8.8% and 3.7%, respectively. The epidemiological determinants for the occurrence of these species were investigated using Poisson or logistic regression models. The region of the farm, the recent use of acaricides and the presence of birds, such as saffron finch (Sicalis flaveola), feral pigeon (Columba livia) and Guira cuckoo (Guira guira) around the farms were related to the epidemiology of M. cornutus. Infestation by M. stramineus was associated with age of birds, number of birds per cage and the presence of Guira cuckoo and Chopi blackbird (Gnorimopsar chopi) near the poultry houses. The occurrence of M. pallidulus was influenced by the type of facilities, presence of cattle egret (Bubulcus ibis) and free-range domestic hens around the farm. The use of wire mesh nets in the houses and of forced moulting did not influence lice infestation. PMID:26642864

    The concentrations of rare earth elements (REEs), thorium and uranium were determined in liverworts (Noteroclada confluens (Tayl.) and Dumortirea hirsute (Sw.) Nees), in mosses (Leucobryum martianum (Hornsh.) Hampe, Vesicularia vesicularis (Schwaegr.) Broth., Pyrrhobruym spiniforme (Hedw.) Mitt. and Sematophyllum subsimplex (Hedw.) Mitt.) and in the soil upon which they were growing. The samples were collected on the margins of the main streams of the Tripui Ecological Station, located in the valley of the Tripui stream near the town of Ouro Preto, Minas Gerais State, Brazil. For decades, this Station has been the object of interest of many studies due to its historical, ecological and environmental importance. Analyses in bryophytes (mosses and liverworts) were determined by inductively coupled plasma mass spectrometry (ICP-MS) and in the soil samples by using neutron activation analysis (NAA), specifically the k{sub 0}-standardization method and the energy dispersive spectrometry technique (EDS). Lanthanum (La), cerium (Ce) and neodymium (Nd) were present in higher concentrations in soils and bryophytes than other REEs. It was observed that in all the collected bryophytes species the elements Th, U, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb were transferred from the soil water to these plants. These bryophytes presented different capacities of accumulating these elements with the liverworts (Noteroclada confluens and Dumortirea hirsute) and the moss Leucobryum martianum showing a more efficient accumulation capacity than the other bryophyte species.

    Full Text Available Brazil has great biodiversity, which is observed in the Cerrado biome of the tropical Brazilian savanna. The objectives of this study were to isolate and identify bacteria from Psychotria hoffmannseggiana with potential cellulase and pectinase production and with antagonistic activity against Aspergillus carbonarius, an Ochratoxin A (OTA producer. Ripe fruit were collected in the region of Passos City in the preserved Cerrado area in Minas Gerais State, Brazil. Serial dilutions were performed, and the bacteria isolated were biochemically characterized and identified by sequencing. To analyze the production of enzymes, the bacteria were cultivated in CMC and pectinase media. The better enzyme producers were optimized for production. Assays on the antagonistic activity for growth and sporulation were carried out in co-culture (bacteria and filamentous fungi. TLC was performed to verify the mycotoxin production. The predominant microbiota were Gram-negative bacteria belonging to the Enterobacteriaceae family. Some isolates showed potential for enzymatic and antagonistic activity, especially the isolate identified as Lysinibacillus fusiformis. This species was a better producer of cellulases (maximum activity: 103.1 mg glucose min.-1 mg-1 protein. In conclusion, the bacteria isolated from Psychotria hoffmannseggiana showed biotechnological potential for agro-industry and the environmental aspect.

    Local knowledge of biodiversity has been applied in support of research focused on utilizing and management of natural resources and promotion of conservation. Among these resources, Pequi (Caryocar brasiliense Cambess.) is important as a source of income and food for communities living in the Cerrado biome. In Pontinha, a "quilombola" community, which is located in the central region of State of Minas Gerais, Brazil, an ethnoecological study about Pequi was conducted to support initiatives for generating income for this community. Data were collected through semi-structured interviews, participant observation, and crossing. The most relevant uses of Pequi were family food (97%), soap production (67%), oil production (37%), medical treatments (17%), and trade (3%). Bees were the floral visitors with the highest Salience Index (S=0.639). Among frugivores that feed on unfallen fruits, birds showed a higher Salience (S=0.359) and among frugivores who use fallen fruits insects were the most important (S=0.574). Borers (folivorous caterpillars) that attack trunks and roots were the most common pests cited. According to the respondents, young individuals of Pequi are the most affected by fire due to their smaller size and thinner bark. Recognition of the cultural and ecological importance of Pequi has mobilized the community, which has shown interest in incorporating this species as an alternative source of income. PMID:27058602

  2. Iron-containing pigment from an archaeological rupestrian painting of the Planalto Tradition in Minas Gerais, Brazil

    International Nuclear Information System (INIS)

    Archaeological rupestrian arts of the Planalto Tradition are of relatively widespread occurrence all over the land area of the state of Minas Gerais (MG), Brazil. They are typically composed by monochromic zoomorphic figures, especially of cervids, mainly in red or orange color. A fragment of a rock wall containing an archaeological painting was collected at the Itanguá site, in the municipality of Senador Modestino Gonçalves (geographical coordinates, 17° 56′ 51″ S 43° 13′ 22″ W), MG. The rock piece was covered with an archaeological painting with pigments of two different hues of red. The X-ray fluorescence (XRF) analysis revealed only a slight difference in Fe and P content for the two different color zones. The pigment materials on this small fragment of rock were analyzed by X-ray diffraction on the conventional incidence mode (XRD) and on grazing incidence X-ray mode (GIXRD), scanning electron microscopy with energy dispersive x-ray detector (SEM/EDS) and conversion electron Mössbauer spectroscopy (CEMS) at room temperature. Results indicated the occurrence of mainly hematite but also of diopside in the pigment. CEMS at RT reveal the presence of hematite and (super)paramagnetic ferric components. In order to confirm these results a small amount of powder from the painting pigments was also analyzed by transmission Mössbauer spectroscopy at 20 K

    This is a cross-sectional population-based study (n = 763) conducted in the north of the State of Minas Gerais, which aimed to investigate the prevalence of tooth decay among adolescents and to identify the potential determinants of same. Probability sampling by conglomerates in multiple stages was used. Trained and calibrated professionals performed the data collection by means of intraoral examination and interviews in the previously selected households. In the analysis of the determinant factor for the presence of tooth decay, hierarchical binary logistic regression models were used. The prevalence of tooth decay, decayed, missing and filled teeth were 71.3%, 36.5%, 55.6% and 16%, respectively. The following averages were observed: DMFT (3.4 teeth), number of decayed (0.8 teeth), restored (2.4 teeth) and missing (0.2 teeth). The incidence of tooth decay was higher among adolescents who stated they were black/indigenous/brown (OR = 1.76), lived in crowded households (OR = 2.4), did not regularly visit or had never been to a dentist (OR = 1.9), used public or philanthropic services (OR = 1,8), had smoking habits (OR = 4.1), consumed alcohol (OR = 1.8), perceived their oral health negatively (OR = 5.9 and OR = 1.9) and had toothac in the last six months (OR = 2.0).

    Full Text Available ABSTRACT Environmental pollution is a problem that has been noted due to changes in the environment, affecting natural resources. Regarding the soil, it may offer great potential for waste disposal. Thus, this study aims to propose criteria for evaluating local suitability for waste disposal, according to soil and terrain attributes for southern Minas Gerais State, and to apply those criteria to define the most appropriate locations for installation of septic systems in a pilot watershed. Literature and the authors' experience were used to propose the more important criteria regarding the suitability of sites for waste disposal. The set of attributes taken into account was grouped into four suitability classes: Adequate, Regular, Restricted and Inadequate. The defined criteria and considered limiting were: soil depth, texture, textural gradient, structure, natural drainage, water infiltration, type of surface horizon, water table depth, depth of perched water table, distance from water bodies, relief, stoniness, rockiness and risk of flooding. From these, soil depth, natural drainage, water table depth, relief and distance from water bodies were adopted for the installation of septic systems. From the total area of the watershed, 5.29% fit in the Adequate suitability class. The Regular, Restricted, and Inadequate sites accounted for, respectively, 19.72%, 41.99% and 33% of the wathershed. Factors such as soil and terrain attributes provide a basis for defining more appropriate places for waste disposal. Future work should involve the refinement of these propositions, since there are rare studies in this research line in Brazil.

    2015-10-01

    Full Text Available Black scale, Saissetia oleae (Olivier (Hemiptera: Coccidae is an important pest of olive trees (Olea europaea L. that requires the use insecticides for its control. Parasitoids are important regulating agents of this pest, but currently, no information on its complex of natural enemies and their impact on black scale in Brazilian conditions exists. This study focused on identifying parasitoid wasps that were associated with the black scale on olive trees to establish their relative abundance and rate of parasitism. Samplings were maintained in an olive orchard located in Maria da Fe, south of the state of Minas Gerais, Brazil, and infested branches were stored in emergence containers to recover parasitoids. Another group was kept in Flanders batteries to evaluate the rate of parasitism in approximately 100 scales. Sixteen parasitoid species were collected during the sampling period, and the most common species were Coccophagus caridei (Brèthes (Hymenoptera: Aphelinidae, Diversinervus elegans Silvestri (Hymenoptera: Encyrtidae, and Mesopeltita truncatipennis (Waterston (Hymenoptera: Pteromalidae, the latter of which was most abundant and frequent. Parasitism ranged from 3 to 31% with peaks in summer and autumn. This level could be considered insufficient to hold the black scale under the economic injury level; however, these parasitoids should be preserved for contributions to population regulation.

    International Nuclear Information System (INIS)

    The present report refers to the Ponte Nova Sheet (SF.23-X-B-II) systematic geological mapping, on the 1:100.000 scale. The Sheet covers the Zona da Mata region, Minas Gerais State, in the Mantiqueira Geotectonic Province, to the eastern part of Sao Francisco Geotectonic Province, as defined in the project. The high grade metamorphic rocks to low amphibolite, occurring in the area were affected by a marked low angle shearing transposition, and show diphtheritic effects. Archaean to Proterozoic ages are attributed to the metamorphites mostly by comparison to similar types of the region. Three deformed events were registered in the region. Analysis of the crustal evolution pattern based on geological mapping, laboratorial analyses, gravimetric and air magnetometry data, and available geochronologic data is given in the 6. Chapter, Part II, in the text. Major element oxides, trace-elements, and rare-earths elements were analysed to establish parameters for the rocks environment elucidation. Geochemical survey was carried out with base on pan concentrated and stream sediments distributed throughout the Sheet. Gneisses quarries (industrial rocks) in full exploration activity have been registered, as well as sand and clay deposits employed in construction industry. Metallogenetic/Provisional analysis points out the area as a favorable one for gold prospection. (author)

    Intestinal parasites are a major public health problem in developing countries, most prevalent in areas where sanitation is poor and the population's hygiene is inadequate. They affect people of all ages, although school-age children are the most susceptible. In this study, we investigated the presence of intestinal parasites in the shared environments of a public school in the town of Diamantina, Minas Gerais State. From December 2012 to February 2013, samples were collected for three months (once a month) by using the Graham method (1941), in duplicate, by affixing a 6 x 5 cm clear tape, six times in each collection site, in a space of about 30 cm2. Then, each tape was positioned longitudinally on a microscope slide and the identification of the biological forms of the parasites was performed with the aid of a 40X objective from an optical microscope. Eleven sites were selected for sampling. Cysts of Entamoeba coli were the most frequently found in this study (50%), followed by Hymenolepis diminuta eggs (27.6%), Iodamoeba butschllii cysts (5.6%), Ascaris lumbricoides eggs (5.6%), Taenia species eggs (5.6%) and hookworm eggs (5.6%). The highest positivity rates were found in the samples drawn from the cafeteria's eating table. The results have indicated the need to improve the cleaning in the school environments, as well as the development of educational practices that may help in the preservation of public health.

A fragment of a rock wall containing an archaeological painting was collected at the Itanguá site, in the municipality of Senador Modestino Gonçalves (geographical coordinates, 17° 56′ 51″ S 43° 13′ 22″ W), MG. The rock piece was covered with an archaeological painting with pigments of two different hues of red. The X-ray fluorescence (XRF) analysis revealed only a slight difference in Fe and P content for the two different color zones. The pigment materials on this small fragment of rock were analyzed by X-ray diffraction on the conventional incidence mode (XRD) and on grazing incidence X-ray mode (GIXRD), scanning electron microscopy with energy dispersive x-ray detector (SEM/EDS) and conversion electron Mössbauer spectroscopy (CEMS) at room temperature. Results indicated the occurrence of mainly hematite but also of diopside in the pigment. CEMS at RT reveal the presence of hematite and (super)paramagnetic ferric components. In order to confirm these results a small amount of powder from the painting pigments was also analyzed by transmission Mössbauer spectroscopy at 20 K.

    Full Text Available Este artigo propõe um estudo do texto da proposta curricular do Estado de Minas Gerais, verificando aspectos da relação instaurada entre a instância de produção da proposta – a Secretaria de Educação – e a instância de destinação dessa proposta – o professor de português da rede estadual de ensino. Centrando a atenção no emprego dos conectores, a análise realizada adota os pressupostos teóricos do Modelo de Análise Modular do Discurso, para investigar em que medida esse emprego é decorrente da maneira como a Secretaria de Educação “imagina” o professor ao qual se dirige. O que se constatou foi um predomínio dos conectores que marcam a relação genérica de argumento. Na proposta curricular, esses conectores são empregados com a função de direcionar a leitura do professor, explicitando que as informações por eles introduzidas são argumentos, justificativas, explicações ou exemplos, cujo papel é o de convencer esse professor de que novas concepções de língua e de linguagem devem guiar a sua prática em sala de aula.

    Full Text Available Este artículo tiene como objetivo analizar la historia de una empresa familiar del Estado de Minas Gerais e identificar los principales valores que influyen en su gestión. Se realizó un estudio relacionado a su historia familiar, mediante el análisis documental del acervo empresarial y de entrevistas con tres miembros de su actual consejo administrativo: dos miembros de la familia y un director veterano. Para la caracterización de la empresa investigada, se utilizó el modelo de Gersick et al. (2006, que analiza la evolución de las empresas familiares en tres variables: propiedad, familia y gestión/empresa. Los valores familiares y organizacionales fueron evaluados por la propuesta teórica de los Tipos Motivacionales de Valores de Schwartz (1992, adaptada por Oliveira y Tamayo (2004. Los resultados muestran que los valores familiares y la gestión de las empresas se entrelazan, causando situaciones y reflexiones sobre el mantenimiento de los valores organizacionales. Los valores familiares se tornan actuantes en las acciones de la empresa, por medio de los ejemplos vividos por las generaciones que preceden, y son fundamentales para que las directrices de la organización estén, de forma sistemática, presentes en las políticas de la empresa o sean vivenciadas por todos, haciendo con que el cotidiano organizacional tenga un referencial positivo de los valores practicados.

    Full Text Available This study aimed to evaluate the postharvest behavior of peach cv. 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 Comumente, as metodologias utilizadas e recomendadas para estimar o requerimento d’água pelas plantas são baseadas em elementos meteorológicos, razão por que o objetivo deste trabalho foi analisar a influência dos elementos meteorológicos na estimativa da evapotranspiração de referência (ET0 no estado de Minas Gerais. Os valores de ET0 foram estimados pelo método de Penman-Monteith-FAO, a partir de dados diários, referentes a um período de 17 anos. A influência de cada elemento meteorológico no valor da ET0 foi determinada por testes de sensibilidade e por análises em mapas interpolados para cada elemento. Observou-se nos resultados que, em geral, a ET0 foi bastante variável em Minas Gerais chegando a apresentar valores médios anuais de 2,51 mm d-1 até valores de 4,59 mm d-1. A análise de sensibilidade revelou que o efeito da variação da maioria dos elementos meteorológicos sobre o valor da ET0 foi significativo entre as diferentes localidades do estado de Minas Gerais, com destaque para o déficit de pressão de vapor e para a velocidade do vento, além da radiação solar, que foi o elemento meteorológico que mais influenciou a estimativa da ET0.In general the methodologies most used and recommended to estimate crop water requirements are based on meteorological data. The aim of this study was to evaluate the effect of some meteorological elements on reference evapotrasnpiration (ET0 estimate in Minas Gerais State, Brazil. The values of ET0 were estimated daily by the Penman-Monteith-FAO method, using daily data over a period of 17 years. The influence of each meteorological element on ET0 values was determined by sensitivity tests and interpolated map analysis for each element under study. The results showed that the reference evapotranspiration is very variable in Minas Gerais, with annual average values between 2.51 to 4.59 mm d-1.

  19. Evidences of a tangential proterozoic tectonic from Quadrilatero Ferrifero, Minas Gerais state, Brazil

    International Nuclear Information System (INIS)

    Radiometric Rb/Sr ages of 2,1 - 2,2 Ga determined for milonites of the Caete complex, combined with tectonic relationships among the sequences of the Espinhaco, Minas and Rio das Velhas Supergroups, suggest that the thrust and fold tectonic style observed around Caete results from two deformation episodes, with similar vergence and style. The parautochthonous domain in Caete Region has been affected by both deformations episodes (Early Proterozoic and Upper Proterozoic) whereas the allochthonous domain apparently was affected only by the younger episode. A preliminary analysis of the Quadrilatero Ferrifero as a whole, considering these two major deformation episodes, is compatible, at least in part, with the large scale features observed in maps. In an effort to understand the tectonic framework of Q.F. an speculation is made on av evolutive model, considering also the existence of two district extensional events (Late Archean and Middle Proterozoic), respectively related to the deposition of Minas and Espinhaco Supergroups in a rift/aulacogen systems.

Conhecer os aspectos demográficos e clínicos de pessoas assistidas por programas de atenção ao estomizado é essencial para o estabelecimento de protocolos assistenciais visando à melhoria do cuidado prestado. Trata-se de estudo descritivo, visando caracterizar os pacientes estomizados residentes em uma cidade de Minas Gerais e inseridos no Programa de Atenção à Pessoa Ostomizada do local, no período de 1994 a 2006. A amostra foi constituída por 12 pacientes, todos colostomizados, com diagnóstico inicial, em ordem de ocorrência, de câncer de reto, de fístula vesicorretal e de câncer pélvico com acometimento das alças intestinais. Complicações no estoma ou na pele ao redor deste foram observadas em 66,1% da amostra, e 58,30% dos pacientes estavam estomizados há dois anos ou mais. Os pacientes relataram alterações nos aspectos físicos e emocionais após a realização do estoma, interferindo em sua qualidade de vida. Constatou-se, porém, que para a maioria dos pacientes, o programa é considerado apenas um centro de concessão de dispositivos.

    Full Text Available Semi-systematized interviews were conducted with 100 dairy cattle producers in the municipality of Divinópolis, Minas Gerais, with the aim of ascertaining their perceptions regarding the importance of Rhipicephalus (Boophilus microplus and of combating it. Content analysis was performed and the frequency distribution of each of the variables was used to construct profiles of the producers interviewed. The production losses caused by ticks were perceived incompletely by the producers, who were unaware of the pathogen transmission caused by the parasite and the indirect losses through combating it, such as the cost of acaricide and labor. The combat operations were performed in a traditional manner, with an excessive number of inefficient treatments that aimed to control the level of infestation at that moment. The quality of the acaricide dipping/spraying applied was affected by the quality of the equipment used to apply the products, lack of knowledge of the mode of action of these products, lack of the specific information needed and lack of motivation caused by unawareness of the disadvantages of chemical combat. It was concluded that the lack of knowledge about combat methods and the acceptance of endemicity of the parasitosis were impediments to changing the realities encountered.Entrevistas semissistematizadas foram aplicadas a 100 produtores de bovinos leiteiros do município de Divinópolis, Minas Gerais, com o objetivo de verificar a sua percepção sobre a importância de Rhipicephalus (Boophilus microplus e seu combate. Foi feita "análise de conteúdo" e a distribuição de frequência de cada uma das variáveis para a construção de perfis dos produtores entrevistados. Os prejuízos causados à produção pelo carrapato são percebidos de forma incompleta pelos produtores, que ignoram a transmissão de patógenos pelo parasito e as perdas indiretas pelo combate, como o custo do carrapaticida e da mão de obra.

    Full Text Available O objetivo dessa pesquisa foi estudar o perfil do absenteísmo em uma empresa bancária estatal e estimar a prevalência de afastamentos pelas doenças que mais acometeram seus trabalhadores. Foi realizado um estudo transversal, descritivo e quantitativo abordando absenteísmo e prevalência de causas de afastamento em um banco estatal no estado de Minas Gerais, no período de 1998 a 2003. Os índices de absenteísmo apresentaram distribuição heterogênea, estando em queda no período estudado, exceto a taxa de freqüência, devido a modificações nos números que compõem seus numeradores e denominadores. As prevalências das doenças osteomusculares e dos distúrbios mentais e comportamentais foram 33,25 e 22,21 afastamentos por 1.000 trabalhadores, respectivamente. Houve predomínio de afastamentos de trabalhadores do sexo feminino, com idade entre 40 e 49 anos de idade, com tempo de empresa superior a 21 anos e com funções com menores valores de remuneração. O estudo indicou que as doenças osteomusculares e do tecido conjuntivo que antes predominavam na empresa estão em queda. Houve também ascensão dos distúrbios mentais e comportamentais, indicando possível mudança no perfil de adoecimento. Mais estudos são necessários para a explicação dos resultados observados.The purpose of this paper was to study the profile of absenteeism in a state bank and to establish the more frequent causes for sick leaves among the members of the staff. A cross-cut, descriptive and quantitative study was developed for approaching absenteeism and its most frequent causes in a state bank in the state of Minas Gerais between 1998 and 2003. The absenteeism rates were homogenous, with a decrease during the period of the study, except for the frequency rates, as a result of alterations in their numerators and denominators.

    Full Text Available This study evaluates milk producers' knowledge regarding cattle ticks and practices for controlling them. Ninety-three dairymen in Minas Gerais were interviewed. These producers had no information regarding acaricide efficiency tests. To analyze the information, open responses were categorized through "content analysis", and descriptive analysis consisting of extracting the profile highlighted by the highest frequencies. The association between schooling level and knowledge was tested by means of chi-square trend tests. It was observed that 92.3% had no knowledge of the non-parasitic period. For 96.4%, what determined the time to apply treatment was the degree of tick infestation; 93.3% used spray guns to apply the acaricide. In seeking to cross-correlate the biological and control variables with education, cooperative action, length of experience and herd size, it was found that there was a linear association between schooling level and implementation of acaricide solution preparation. The other factors didn't show any significant association. These data demonstrated the need to instruct the producers in relation to the biology and control of Rhipicephalus (Boophilus microplus. It was concluded that the majority of milk producers were unaware of cattle tick biology and the factors that influence choosing an acaricide, which makes it difficult to implement strategic control.Este estudo teve como objetivo avaliar o conhecimento dos produtores de leite sobre o carrapato dos bovinos e seu controle. Foram entrevistados 93 produtores de leite de Minas Gerais. Estes produtores não tinham informação sobre testes de eficiência de carrapaticidas e controle de carrapatos. Foi testada associação entre a escolaridade e as práticas e conhecimento sobre os carrapatos e constatou-se que 92,3% dos produtores nada sabiam sobre o período não-parasitário.

Procura-se, dessa forma, contribuir para o debate sobre o impacto da repetência no aprendizado do aluno. No Brasil, devido à carência de dados longitudinais que possibilitem uma comparação mais apurada entre os repetentes e os promovidos, considerando seus desempenhos antes e depois do evento da repetência, a maioria dos estudos enfoca principalmente o impacto das políticas de ciclos no desempenho do aluno. Por meio dos dados do Programa de Avaliação da Alfabetização (avaliação externa realizada anualmente nas escolas públicas de Minas Gerais, foi possível constituir uma base de dados longidudinal que identificasse os alunos repetentes e os não repetentes. Para tentar explicar o desempenho dos alunos repetentes e não repetentes, utilizou-se como marco norteador a abordagem da Função de Produção Educacional e como base metodológica, os modelos hierárquicos. Os resultados indicam que tanto os alunos que repetiram quanto os que não repetiram apresentaram crescimentos bastante importantes nas médias de proficiência. No entanto, os modelos hierárquicos construídos demonstram que, dentre dois alunos com mesma proficiência em 2008, tendo um deles repetido e o outro não, aquele que não repetiu tende a apresentar maior nível de proficiência em 2009. Outro achado importante refere-se ao fato de que o resultado do aluno é muito influenciado pelo resultado geral da escola.The objective of this work is to evaluate if retaining pupils of the third year of fundamental education in 2009 brought benefits to their learning in comparison to pupils that advanced to the fourth year.

    Full Text Available A exploração desenfreada dos ecossistemas tropicais, principalmente o Cerrado, tem provocado uma redução nos indivíduos de inúmeras espécies medicinais, levando prejuízos para toda a população. A falta de informações sobre o extrativismo tem dificultado o uso de estratégias eficazes de manejo e conservação das espécies do cerrado. A fava-d'anta é uma dessas espécies nativas que possuem potencial econômico, principalmente devido à rutina, que é usada na fabricação de fármacos e de cosméticos. O objetivo deste estudo foi analisar os aspectos da atividade de coleta da fava-d'anta pelos coletores e comerciantes. Realizou-se entrevista estruturada com 61 extrativistas, sendo 44 coletores e 17 comerciantes em oito municípios do Norte de Minas Gerais. Constatou-se que a maioria dos entrevistados são homens casados, analfabetos ou com a primeira etapa do ensino fundamental. A coleta da fava-d'anta, apesar de pouco rentável, é uma alternativa para os coletores, sendo a renda inferior à dos comerciantes que já estão nesta atividade de compra da fava-d'anta há mais de 10 anos. A faixa etária de adulto e adulto/idoso são as mais representativas. A época de maior produção ocorre entre os meses de abril a julho, a bienalidade da produção leva à mudança do local de extração. Observou-se o auxílio de toda a família na atividade. Utiliza-se como instrumento de coleta o podão, a foice, facões e outras ferramentas que danificam as árvores. A maior dificuldade para os coletores é a secagem e, para os comerciantes, a venda. O plantio ou a produção de mudas não tem sido prática habitual dos entrevistados.The uncontrolled exploitation of tropical ecosystems, especially Cerrado, has caused a reduction in individuals of many medicinal plant species, causing damage to the entire population.

    Full Text Available Neosporosis is an important cause of abortion in cattle and information on their genetics and host parasite relationships are desirable. Neospora caninum samples obtained from 24 bovine fetuses from Minas Gerais, were genetically analyzed in part of the rDNA region, coding for rRNAs. Previously, brain, heart, liver, skeletal muscle, lung, kidney, spleen, thymus, lymph nodes, ovary or testis, uterus and skin of the ear were analyzed by conventional histopathology and immunohistochemistry. Of these, eight had lesions compatible in the brain and heart and two also in skeletal muscle and liver. Three brains showed antigen identification in immunohistochemistry. Brain and heart tissues were subjected to DNA extraction for PCR, whose product of 588 bp of ITS-1 region was sequenced in three samples. We obtained 96% similarity with dozens of sequences N. caninum deposited in GenBank. The phylogenetic tree showed great conservation among isolates of N. caninum in this study and those deposited in GenBank, while well-defined and specific branches were generated against other Apicomplexa. PCR for this region is useful as a diagnosis, with good analytical specificity, but the ITS-1 region is not suitable for genetic differentiation intra species because the sequences obtained were identical to the others analyzed.A neosporose é uma importante causa de abortos em bovinos, e informações sobre sua genética e relação parasito-hospedeiro são desejáveis.

    Full Text Available A radiação solar é um dos elementos responsáveis pela manutenção da vida no planeta. Apesar da sua importância, o registro da radiação solar não é feito na maioria das estações meteorológicas convencionais, uma vez que nem todas dispõem de equipamentos para medi-la, tendo que recorrer a métodos de estimação empíricos. Com o intuito de testar e calibrar equações para estimar a radiação solar, foram coletados dados de quatro estações meteorológicas pertencentes ao Instituto Nacional de Meteorologia (INMET para representar a região climática noroeste de Minas Gerais, no período de 2008 a 2010. Com base nesses dados, foram testados e calibrados nove modelos para estimar a radiação solar global. Todos os modelos utilizam temperatura máxima e mínima do ar como preditores e dois deles utilizam também a precipitação pluviométrica. Os modelos mais precisos foram de De Jong e Stewart, Bristow e Campbell, Donatelli e Campbell e o modelo dois de Hunt, com raiz quadrada do quadrado médio do erro em torno de 3,1MJ m-2 d-1 e coeficiente de determinação em torno de 62%. No entanto, todos esses modelos apresentaram tendência de superestimação para valores de radiação inferiores à média e subestimação para valores superiores. Portanto, há necessidade de propor novos modelos que minimizem essa tendência.Solar radiation is a component responsible for maintaining the life on the planet. Despite its importance, solar radiation is not recorded in most conventional meteorological station since not all have equipments to measure it, and then, it is usual to use empirical solar radiation estimation methods. In order to test and calibrate models for estimating solar radiation data were collected from four meteorological stations belonging to the National Institute of Meteorology (INMET to represent the climatic region northwest of Minas Gerais for the period from 2008 to 2010.

    Full Text Available O uso de modelos matemáticos para predição da chuva é uma forma prática e precisa para determinação do valor a ser aplicado em projetos, sendo útil para localidades desprovidas de informações pluviométricas. Objetivou-se ajustar o método de Bell, que possui características de regionalização para a chuva de projeto, com base em equações de chuvas intensas e modelos de probabilidade de Gumbel de estações meteorológicas do Estado de Minas Gerais ajustando, também, um modelo para cada região do estado. Avaliaram-se os modelos considerando-se o coeficiente de determinação e os erros médios em relação aos dados originais. Para validação, trabalhou-se com três estações meteorológicas da região Norte não usadas para ajuste do respectivo modelo. Foram analisadas três metodologias para estimativa da chuva intensa padrão (h(60,2, que pondera o método usado, ressaltando-se a média aritmética, a média ponderada pelo inverso do quadrado da distância e a predição geoestatística (krigagem. Observou-se que os modelos possuem bons indicadores estatísticos e a validação produziu erros baixos, mostrando que os modelos podem ser aplicados, especialmente se a krigagem for usada para estimativa do parâmetro h(60,2.The use of mathematical models for predicting rainfall is a practical and accurate way of determining this parameter to be applied to regions which do not have any precipitation data. Based on the intense rainfall equations and Gumbel's probability model for maximum daily precipitation of meteorological stations in Minas Gerais State, the objective of this work was to adjust the Bell's Method, with regional features, for rainfall, adjusting one model for each region. The regional parameters were estimated by non-linear multiple regression, using Gauss-Newton's method. The goodness of the models was evaluated by the coefficient of determination and mean errors of prediction as compared to the original data

Os benefícios são atribuídos à geração de renda (alternativa para pequenos e médios produtores rurais, impostos, divisas e incremento no PIB. As novas exigências do mercado, em termos de competitividade, levaram as empresas a criarem os programas de fomento florestal como forma de expandir a oferta de madeira e garantir sua base produtiva. Nesse contexto, surge a necessidade de se identificarem os fatores que determinam a realização de novos contratos de fomento florestal. A amostra estudada foi composta pelos produtores rurais da mesorregião do Vale do Rio Doce, Minas Gerais, que realizaram pelo menos um contrato de fomento entre os anos de 1995 e 2006. Os dados foram coletados por meio de questionários semiestruturados no ano de 2006. Para identificar os fatores, utilizou-se a Análise Estatística Multivariada, especificamente a técnica de análise de discriminante. Os resultados apontaram que o sistema de medição da madeira (SISMED, a área contratada (ACONTRAT e o tamanho da propriedade (TAMPROP foram, nessa ordem, os principais determinantes para a realização de novos contratos. Desse modo, sugere-se que as empresas florestais desenvolvam programas de acompanhamento técnico e formação dos produtores fomentados, no intuito de reduzir as desconfianças no SISMED e aumentar o volume de áreas plantadas por meio do fomento.The forestry sector has played an important role in the socio-economic development of wood-producing regions. Benefits include private income (an alternative for small and medium-sized rural producers, government tax income, balance of payment advantages, and increasing GNP. New market demands in terms of competitiveness have led cellulose companies to create private woodlot programs as a way to expand timber supplies and guarantee a productive basis.

    Full Text Available O Vale do Rio Doce, MG, apresenta um histórico de ocupação e uso do solo que favorece a degradação ambiental, em que predominam pastagens sob o uso constante de queimadas. Os sistemas agroflorestais têm-se mostrado eficientes na recuperação de áreas degradadas. Neste estudo foram avaliados os efeitos de um sistema agroflorestal na recuperação do solo em área degradada por pastagem na comunidade de Ilha Funda, Município de Periquito, Minas Gerais. A implantação do sistema se deu em 1994 e está sendo conduzido segundo os princípios agroecológicos, potencializando a regeneração natural e a sucessão de espécies. Em 1998, foram coletadas amostras de solo na área em recuperação e em duas áreas adjacentes: uma área degradada, que se encontrava em condições semelhantes às da área em recuperação no início do processo, e outra ocupada por pastagem. Foram determinados atributos químicos do solo e realizada a caracterização da matéria orgânica. O solo da área em recuperação com sistema agroflorestal mostrou-se em melhores condições do que o solo sob pastagem e o da área degradada, apresentando maior dinâmica do carbono orgânico e maior disponibilidade de nutrientes. Embora o teor de carbono orgânico total apresentado pelo solo sob pastagem tenha sido maior que nas demais condições avaliadas, o solo do sistema agroflorestal já está se igualando ao da pastagem no acúmulo das formas mais estáveis de carbono e apresentando maior dinâmica das frações orgânicas menos estáveis. Este estudo comprovou a eficiência dos sistemas agroflorestais, conduzidos segundo os princípios agroecológicos, na recuperação de áreas degradadas.Vale do Rio Doce, MG presents an ancestral history of occupation and use of soil that has contributed to environmental degradation, mostly caused by pasture with fire always being used as a form of management.

    Full Text Available A trombose é reconhecidamente uma doença de caráter multifatorial. Sua ocorrência está intimamente relacionada à presença de fatores genéticos e adquiridos que concorrem isoladamente ou em associação para o seu desencadeamento. No entanto, a frequência dos fatores genéticos pode variar de acordo com a origem étnica e com outros aspectos epidemiológicos dos grupos de indivíduos e populações estudadas. No Brasil, dados referentes a indivíduos brasileiros e em especial do estado de Minas Gerais são escassos. O objetivo do presente estudo foi investigar a frequência das mutações fator V Leiden e G20210A no gene protrombina em 1.103 indivíduos com suspeita clínica de trombofilia, empregando a técnica da reação em cadeia da polimerase seguida de restrição enzimática (PCR-RFLP.

    Full Text Available A study to determine the sociocultural factors influencing knowledge, attitudes, and practices of individuals from a small community toward Schistosoma mansoni infection was carried out in an endemic area in the State of Minas Gerais, Brazil. The study used qualitative approaches to collect data from school-aged children and teachers. Specific findings were that the individuals interviewed were aware of the disease, but also held inaccurate popular beliefs about transmission. Misconceptions coexisted with accurate knowledge both in children and teachers. The disease was not seen as a major health problem and did not affect their activities since it did not cause severe symptoms in most of the individuals. Although the majority of the participants related transmission to water and lack of sanitation, they did not take any preventive measures since their subsistence is highly dependent on irrigation, farming, fishing, and other essential work that is directly related to water activities. The authors discuss the development of a health education program based on the knowledge and perception of individuals about the disease and its determinants as being important for the context and behavioral change.Este estudo foi realizado em área endêmica do Estado de Minas Gerais, Brasil, com o objetivo de determinar os fatores sócio-culturais que influenciam o conhecimento, as atitudes e práticas dos indivíduos da comunidade em relação a esquistossomose mansoni.

    The present situation of the environmental licensing process have been slow and complicated, in relation to the current conception of the sustainable environmental development in the country. The enterprises and impacting activities are being discussed and analysed through a great number of environmental laws and specific laws to each enterprise. These laws along with the inexperience of the enterprises and of the many institutions involved in the process are an obstacle to the development. This document presents the legal and institutional aspects of the environmental licensing for the implementation of small hydroelectric power plants. Laws and doctrine related to the topic were researched and concluded for Minas Gerais State with the help of a survey with the enterprises and institutions involved in the process to find out the difficulties that influence the delay of the analysis of the SHPP. The results show that the main barriers are the non-application of the CONAMA resolution 279/2001 to the SHPP, undetermined inspection criteria, excess of environmental programs, technical incapacity, lack of financial resources, non-integration of the institutional organs, the building of SHPP in permanent preservation area, project interfering in the fish fauna, studies an environmental impact with then reports and public audiences. Finally, concludes that the difficulties are based on the non-integration of the institutions and also, being recent, on the inexperience of the actors involved. Therefore, the study suggests on increase of the technical body in the institutions and training of their analysts; hiring of specialized consultancy, implantation of an environmental integrated system, social communication program in the planning phase, fulfillment of the CONAMA resolution 279/2001; integration of public ministry representatives in the licensing organs; application of planning and zoning, deadlines and legal imposition of these deadlines in order to supply the
