    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)

  2. 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

    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.

  4. 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

  5. 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.

    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{sup -}), molybdenum (Mo), sulfate (SO{sub 4}{sup 2-}), 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{sup -}, Zn, Mo, SO{sub 4}{sup 2-}, 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 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 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 Despite closure regulations being recent in Brazil, many mining companies are attempting to adopt best practice and are facing the challenge of closing their mines properly instead of simply complying with current legislation or abandoning the mine site. This paper summarizes mine closure according to both the Brazilian legislation and the "Deliberação Normativa" COPAM Nº 127, that establishes the directives and procedures for environmental assessment at the mine closure stage. Even with the lack of laws and regulations addressing mine closure, the Brazilian mining industry today is at the forefront of environmental impact minimisation techniques. Some case studies in Minas Gerais State, two of them located in the Iron Quadrangle, provide excellent evidence of the industry's rehabilitation expertise. This paper presents an overview of mine closure legislation in Brazil and in the State of Minas Gerais and gives some examples of mine closure programmes in effect. It is intended to highlight the changes on mine closure requirements as well as the best practices on mine closure in the State.Embora as regulamentações sobre fechamento de mina no Brasil sejam recentes, muitas empresas de mineração têm buscado adotar as melhores práticas e estão enfrentando o desafio de fechar as minas da melhor maneira possível, em vez de simplesmente cumprir a legislação vigente ou abandonar o local da mina.

    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.

    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 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.

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.

    Full Text Available The IEF-Asiflor forest incentive program is the result of a joint endeavor that channeled forest restoration funds to promote, according to effective legislation, silvicultural activity in Minas Gerais state. The above partnership was implemented in 2003. In this work we aimed to outline the incentive program per participating IEF administrative region, and to georeference and quantify implemented forest stands according to property size class. To that end, we searched data records of all producers benefiting from the program. We then compiled and processed the data, using ArcMap® application to georeference the rural properties making up the sample. The observations concerning number of assisted properties and area reforested in each property per administrative region was based on seven property size classes, according to the 1996 agricultural census classification of the Brazilian Institute of Geography and Statistics (IBGE. The administrative unit showing the largest assisted area was Centro Norte regional office, with 3,872.25 ha, although Zona da Mata regional office had the largest number of benefiting producers, with 449 producers. Featured among the steel producing hubs concentrating the largest number of Asiflor member plants, Sete Lagoas had the largest reforested area, being closer to the actual plants. The most assisted property size class, both in quantity and in area reforested, was class B, except in Centro Norte regional office where Class E showed a larger area reforested.

    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.

    This paper discusses schistosomiasis transmission in São José da Serra, a village with a population of 500 in the county of Jaboticatubas, Minas Gerais State, Brazil. The area receives thousands of visitors a year for ecotourism. The study was motivated by a case of acute schistosomiasis involving a couple that spent the 2007 Carnival (Mardi Gras) holiday in the area. Stool tests from 268 local residents (53.6% of the population) showed that 35 (13%) were positive for the infection. A comparison with a previous survey (2005) in the same location showed an increase in the schistosomiasis-positive rate from 9.6% to 12.5%, among the 56 individuals who participated in both surveys. A malacological survey of 65 Biomphalaria glabrata snails showed one specimen (1.5%) eliminating cercariae. In a similar survey in 2005, no positive snail specimens were found. The study indicates that active schistosomiasis transmission is occurring in the area, and that integrated educational programs are needed for both the local community and tourists.

    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.

    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 present survey aimed at estimating the seroprevalence of brucellosis in working equines of cattle farms from Minas Gerais State, Brazil, and investigating risk factors associated with the infection. Serum samples from 6439 animals, including 5292 horses, 1037 mules and 110 donkeys, were collected from 1936 herds, between September 2003 and March 2004, in 848 municipalities from the state of Minas Gerais, Brazil. The prevalence of antibodies against smooth Brucella spp. found in equines from Minas Gerais State was 1.37% (95% CI: 0.97-1.78), resulting in a prevalence of herds with infected animals of 4.28% (95% CI: 4.21-4.36). There were differences between regions but these were not of major epidemiological relevance nor were most of them statistically significant, given the considerable overlap of confidence intervals. Nevertheless, the point estimates suggest that the three northeastern regions have slightly higher prevalence than the rest of the state, both at the herd and animal levels. No association of Brucella spp. seropositivity with sex, age or host was observed. In conclusion, the present study showed a low but widespread prevalence of antibodies against smooth Brucella in equines kept in cattle farms in Minas Gerais, a state where bovine brucellosis is also widespread albeit with low prevalence.

    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.

    We received for examination a small colection of ticks captured in the National Park of the Serra da Canastra (MG), between 1979 and 1980. The authors demonstrated the existence of a broad co-accomodation of Amblyomma pseudoconcolor on Edentata of the family Dasypodidae, being Dasypodini the tribe more adjusted to this infestation. In conformity to the Figs 1 and 2, Dasypodini are probably the real hosts of A. pseudoconcolor and also the oldest hosts. For the first time, A. pseudoconcolor is also recorded on Cabassous tatouay, C. unicinctus, Priodontes maximus and Euphractus sexcincuts. Also for the first time A. pseudoconcolor and Amblyomma calcaratum were recorded in the State of Minas Gerais. The ectoparasites are deposited in the "Departamento de Parasitologia da Universidade Federal de Minas Gerais, Brasil".

The analysis of the items through the Item Response Theory, Model 2P, showed appropriate levels of difficulty and discrimination of all items except for item E12, which was extremely difficult. The test information function indicated that the SPM test was relatively easily to carry out by the sample of Minas Gerais. The Flynn effect, or cognitive gains of generation, may be the factor responsible. However, the prediction of school performance (criterion validity using the SPM test is still possible. Implications for professional use are discussed.

    Genetic diversity among local accessions and varieties subsidize plant breeding programs, allowing the utilization of existing variability in plants that have already adapted to local climate conditions. An alternative to studying genetic variability is the study of diversity. The aim of this research was to study genetic diversity among sugarcane accessions and varieties used for the production of craft-distilled cachaça (distilled sugarcane alcohol) in the region of Lavras, Minas Gerais, Brazil. Using a one-way design, an experiment was conducted in the municipality of Perdões, Minas Gerais to evaluate 35 regional accessions derived from germplasm collection expeditions and four varieties. Using morphological descriptions of 46 multicategorical sugarcane characteristics, dissimilarity and Tocher cluster method analyses were performed. Based on the results, it was concluded that genetic diversity exists among the accessions evaluated for the target traits.

    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.

    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.

    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 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.

    Full Text Available No alto Jequitinhonha, nordeste de Minas Gerais, a principal forma de os lavradores adquirirem terra é através da herança, sua própria ou do cônjuge ou, ainda, através da junção das duas. É muito difícil que se adquiram terra por outras vias. Assim, o dono da terra é antes de tudo um herdeiro, e a terra é, principalmente, um patrimônio formado pela família. O objetivo deste artigo foi analisar como posse e uso da terra se compõem com o ambiente e com a família, formando com ambos uma urdidura que passa pelo trabalho, pela herança, pela migração e pelo casamento, fornecendo elementos importantes para compreensão da sociedade rural e das formas de domínio da terra que se estabeleceram naquela região.In the High Jequitinhonha region of northeastern Minas Gerais, Brazil, farmers acquire land principally through inheritance: their own, their spouses, or a combination of the two. The owner of the land is, before anything else, an heir; and the land is primarily a family patrimony. The objective of this article is to add to the understanding of Brazilian rural society and rural forms of land control by analyzing the interaction among land ownership, land use, the environment, and the family, focusing on the effect of this combination on the inheritance process, migration, work, and marriage.

    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.

  2. Simulating Deforestation in Minas Gerais, Brazil, under Changing Government Policies and Socioeconomic Conditions.

    Full Text Available 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.

Estes objetivos são os seguintes: 1 identificar os principais fatores determinantes da inovação nos municípios mineiros a partir dos fatores considerados relevantes pela literatura internacional; 2 determinar a relação que existe entre a estrutura urbana do Estado e a inovação; 3 revelar padrões de associação espaciais e identificar agrupamentos espaciais significativos de produção tecnológica; 4 verificar se ocorrem transbordamentos tecnológicos intermunicipais. O trabalho constatou que a atividade tecnológica é concentrada espacialmente, e tende a ocorrer principalmente ao redor da área metropolitana de Belo Horizonte. A estrutura urbana do Estado é, em parte, causadora desta distribuição espacial da atividade tecnológica, porque a maior parte das cidades não possui escala urbana e requisitos exigidos pela inovação.This paper uses a database of patent applications from the Brazilian Patent Office (INPI to throw some light on the relationship between innovation and regional development in the state of Minas Gerais. The objectives are described as follows: 1 to identify the main determinants of innovation in the municipalities of Minas Gerais considering the variables emphasized by the international literature; 2 to determine the relation existing between the urban structure of the state of Minas Gerais and its innovative performance; 3 to reveal the patterns of spatial associations and to identify significant spatial clustering of technological activity; 4 to verify the occurrence of interregional knowledge spillovers.

    Full Text Available Acid drainage results from exposition of sulfides to the atmosphere. Arsenopyrite is a sulfide that releases arsenic (As to the environment when oxidized. This work evaluated the As mobility in six sulfidic geomaterials from gold mining areas in Minas Gerais State, Brazil. Grained samples (<2 mm were periodically leached with distilled water, during 70 days. Results suggested As sorption onto (hydroxides formed by oxidation of arsenopyrite. Low pH accelerated the acid generation, dissolving Fe oxihydroxides and releasing As. Presence of carbonates decreased oxidation rates and As release. On the other hand, lime added to a partially oxidized sample increased As mobilization.

    Background: Coronary artery disease is the main cause of death in Brazil. In the Brazilian public health system, the in-hospital mortality associated with acute myocardial infarction is high. The Minas Telecardio 2 Project (Projeto Minas Telecardio 2) aims at implementing a myocardial infarction system of care in the Northern Region of Minas Gerais (MG) to decrease hospital morbidity and mortality. The aim of this study was to describe the profile of the patients with acute coronary syndrome (ACS) cared for in the period that preceded the implementation of the system of care. Methods: Observational, prospective study of patients with ACS admitted between June 2013 and March 2014 to six emergency departments in Montes Claros, MG, and followed up until hospital discharge. Results: During the study period, 593 patients were admitted with a diagnosis of ACS (mean age 63 ± 12 years, 67.6% men), including 306 (51.6%) cases of unstable angina, 214 (36.0%) of ST-elevation myocardial infarction (STEMI), and 73 (12.3%) of non-ST-elevation myocardial infarction (NSTEMI). The total STEMI mortality was 21%, and the in-hospital mortality was 17.2%. In the STEMI patients, 46,0% underwent reperfusion therapy, including primary angioplasty in 88 and thrombolysis in six. Overall, aspirin was administered to 95.1% of the patients within 24 hours and to 93.5% at discharge, a P2Y12 inhibitor was administered to 88.7% participants within 24 hours and to 75.1% at discharge. A total of 73.1% patients received heparin within 24 hours. Conclusion: We observed a low reperfusion rate in patients with STEMI and limited adherence to the recommended ACS treatment in the Northern Region of MG. These observations enable opportunities to improve health care. PMID:27355471

    Full Text Available This study was conducted to assess the presence of schistosomiasis mansoni in the "Noroeste de Minas" mesoregion, an area considered non-endemic. 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.

    Full Text Available In 1965, the Brazilian Federal Council of Education institutionalized Postgraduate studies through the 977/65 Legal Bulletin. Minas Gerais was one of the first states to create postgraduate programs, especially in education, which genesis this study focuses with the aim of pointing out ways to write the recent history of Higher Education and highlight the 25th anniversary of postgraduate studies in education at the Federal University of Uberlândia. As a documental research, this study relies upon legal documents and statistical data analysed with a historical and contextual approach. The results show that, once created, postgraduate studies was expanded in connection with Higher Education, received stimulus both from tax and institutional enhancement in Minas Gerais and faced effects of neoliberal policies such as decrease in the number of scholarships and duration of courses. This study allows to conclude that one way to write this history are the teachers’ reports who started the postgraduate practices and turned them into an essential system for the advancement of science.

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 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.

    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.

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.

    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 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.

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.

    This article analyzes the control strategies in place at Morro Velho mine in the Brazilian state of Minas Gerais, and the changes after the implementation of labor legislation during the Vargas administration. The diseases common amongst mine workers, silicosis and arsenicosis, are investigated through statements given by former miners and a book by an anonymous author that discusses the diseases and the power relations between employers and employees, identifying the limitations of the legislation and the workers' struggles. The book presents a striking story of how for many years the British company side-stepped laws such as the insalubrity premium, a right which other mining companies, not only of British ownership, flouted and still flout in different parts of the world.

  1. Preliminary assessment of arsenic concentration in a spring water area, iron quadrangle, Minas Gerais Brazil

    International Nuclear Information System (INIS)

    The attention to environmental exposure to arsenic is increasing in the worldwide. In this scenario, a project is being developed in Santana do Morro, Iron Quadrangle, Minas Gerais, region well known due to natural and anthropogenic occurrence of arsenic. This proposal has several objectives; one of them is to start a procedure of phyto remediation in laboratory aiming at future riparian forests restoration. The main concern is the preservation of water resource and consequently the health of the inhabitants. The study place is close to a water spring. One sampling was carried out, collecting plants, soil and sediment. The Neutron Activation Analysis, k0-method, was applied to determine the elemental concentration, using the TRIGA Mark I IPR-R1 reactor, located at CDTN/CNEN. In this paper, the results are discussed. (author)

    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 Climate change will exacerbate the vulnerability of places and people around the world in the next decades, especially in less developed regions. In this paper, we investigate future scenarios of population vulnerability to climate change for the next 30 years in 66 regions of the state of Minas Gerais, Brazil. Based upon the Alkire & Foster Index, we integrate simulated and projected dimensions of population vulnerability into a Multidimensional Index, showing how scenarios of temperature change would affect each region's relative vulnerability in the future. Results suggest that economic and health dimensions are the highest contributors to increases in temperature-related vulnerability, with the poorest and agribusiness regions being the most impacted in decades to come.

    2016-01-01

    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.

    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.

    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.

  9. 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

    2007-06-01

    Full Text Available This paper examines the post-War industrialization process in the Brazilian State of Minas Gerais, focusing on one of its desirable outcomes, namely the capacity to generate growth through the impact of strong input-output linkages. This process is placed into historical perspective considering the ideas that permeate the economic development debate throughout the period of analysis. Changes in the regional economic structure are assessed through the use of three input-output tables for the years of 1953, 1980 and 1995. By adopting the fields of influence methodology as the analytical core, it is shown that the efforts towards the creation of a more integrated regional economy have generated stronger influence of the targeted sectors (metal products, transportation equipment, chemical, and services. However, structural changes also contributed to strengthen leakage in the system originated in traditional economic activities.

  13. 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).

  14. 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)

    2008-02-01

    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

    Full Text Available The State of Minas Gerais is the largest producer and consumer of charcoal, that is used as term-reducer of iron ore,for producing pig iron. This study analyzed the time series of charcoal prices in four regions of Minas Gerais State. For the analysisof the price series, the SARIMA model was used, for finding a model that better forecasts prices for the four studied areas. The mostappropriate models were chosen using graphical analyses of the standardized residues, autocorrelation functions and partialautocorrelations, stochastic tests and criteria of evaluation of the order of the model. It concluded that: the differences of charcoalprices occur, basically, due to the geographical location; the analyses of domain of the time and domain of the frequency showed thatthere is difference in the price series of the four studied areas; the areas of Sete Lagoas and Belo Horizonte, giving that they are closelylocated, possess similar prices and they generated similar model; the studied areas presented differentiated models and supplied goodadjustments for the observed series.

    2009-04-01

    The State of Minas Gerais, Brazil, is approximately 586.528 km2. From this total, it is believed that about 29,000 km2(Piló 1997; 1999) are composed by carbonatic rocks. With a total of 853 municipalities and some evident environmental problems, the biggest problem is the proper final waste disposal as noticed by Travassos et al (2008). This work is intended to demonstrate the potential degradation of karst scenarios due to the increasing urbanization in the so called "North Vector". There are two State Parks and six other Conservation Units in this region. Historically the cities near this region have been used as dormitory towns. Further north, various ranches, country houses for the weekend and rural hostels are set on karst terrains. The municipalities of Vespasiano, Pedro Leopoldo, Confins, Lagoa Santa, Matozinhos, Funilândia and Prudente de Morais are within the 360 km2-large Environmental Protected Area of the Lagoa Santa Karst. All these municipalities have been facing demographic growth and consequently generate the anthropogenic pressure over the karst. Up to the date on which this abstract was written, the Decree n˚ 6640/2008, signed by the Brazilian government, is in effect. It substituted the previous one, Decree n˚ 99556/1990, which protected the Brazilian speleological heritage. According to the new Decree, now there are no warranties that caves will be protected against infra-structure constructions and mining companies. Besides, it also establishes relevance criteria that point out which caves which can be destroyed without any compensation at all. Certainly the speleological community is already mobilized against this new Decree. Keywords: karst, endokarst, exokarst, Cordisburgo region, Minas Gerais, Brazil.

    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.

Para isso, foram utilizados dados de 169 experimentos conduzidos no período de 1974 a 2004 e que envolveram 16 locais e três safras. A média da cultivar Carioca, comum em todos os experimentos, foi utilizada como estimador do efeito ambiental e a média das cinco melhores linhagens sob avaliação de cada biênio, como efeito fenotípico. A diferença entre essas duas médias forneceu o desvio genético. O coeficiente de regressão linear entre desvio genético Y (variável dependente e o biênio X (variável independente forneceu a estimativa do progresso genético. As interações linhagens x safras e linhagens x anos foram, na maioria dos casos, significativas, contudo, suas contribuições para a variação total foram inferiores a de linhagens x locais. Desse modo, fica clara a necessidade de que os experimentos sejam conduzidos em um maior número de locais.

Foram feitas entrevistas abertas e semi-estruturadas em profundidade com os participantes (30 homens e 22 mulheres, conduzidas no ambulatório ou em suas residências, em municípios rurais da região norte de Minas Gerais. As entrevistas foram transcritas, analisadas em categorias: concepções da doença, trabalho, sociabilidade, informações prévias sobre a doença, modo de vida. A interpretação dos resultados baseou-se na análise de conteúdo. RESULTADOS: Na percepção dos entrevistados, a Aids era "doença de cidade grande" e de "forasteiro", desvinculada da cultura local. Todos os entrevistados se infectaram através de atividades heterossexuais ou homossexuais. A migração rural-urbana é aspecto relevante da infecção do HIV na região devido ao deslocamento em busca de trabalho. CONCLUSÕES: As noções populares de doença contribuem para vulnerabilidade à infecção pelo HIV. É necessário apreender noções culturais locais para melhor entender as categorias de pensamento dessa população, enfocando essas noções ao divulgar informações sobre a doença.OBJECTIVE: To describe behaviors facilitating HIV/AIDS exposure in rural population.

    Full Text Available A cultura do cafeeiro (Coffea arabica L. na região de cerrado do Estado de Minas Gerais, mais especificamente no Alto Paranaíba, está se desenvolvendo com muito sucesso. As doenças e pragas vêm causando redução na produtividade e na qualidade do café produzido. Os ácaros fitófagos fazem parte deste problema, pois causam danos econômicos. Sendo assim, este trabalho teve como objetivo o levantamento da acarofauna em cafeeiros daquela região. Foram feitas quatro amostragens de folhas, ramos e frutos, sendo duas no período das águas e duas no período de seca em 2002 e 2003. Foram identificadas três famílias de ácaros fitófagos, quatro de ácaros predadores e quatro de ácaros generalistas. As espécies de ácaros encontradas foram: Brevipalpus phoenicis (Geijskes, 1939 (Tenuipalpidae; Oligonychus sp.

    Full Text Available Em fins do século XIX e princípios do século XX os fluxos migratórios atingiram proporções significativas em Minas Gerais, especialmente graças à construção de Belo Horizonte e à expansão da lavoura cafeeira na região sul e na Zona da Mata. A partir dos registros da Hospedaria Horta Barbosa, em Juiz de Fora, no ano de 1896, apresentam-se algumas características desses contingentes: sua composição etária e sua origem, bem como a composição dos grupos familiares que migravam. A julgar pelo perfil encontrado nesse ano, os imigrantes que estavam se dirigindo para Minas Gerais ajustavam-se ao padrão da imigração subsidiada, com predomínio dos grupos familiares. O perfil etário e o de sexo diferenciam-se do perfil clássico dos migrantes, no qual predominam os homens jovens.At the end of the 19th century and beginning of the 20th century, the migratory flows to Minas Gerais assumed massive proportions, especially as a result of the construction of Belo Horizonte and of the expansion of the coffee industry in the South region of the state and Zona da Mata. The Registers of the Horta Barbosa Inn, in Juiz de Fora in 1896, reveal some characteristics of this contingent: age composition, origin, and characteristics of migrating family groups. Judging from the profile found in 1896, the immigrants coming to Minas Gerais were mostly of the subsidized immigration type, therefore formed mostly by family groups. Age and sex profiles have been found to differ from the classic profile of the migrant, a contingent formed mainly by young men.

    Based upon several years of experience in investigations with macrozoobenthos in rivers in the states of Minas Gerais and Rio de Janeiro, a biological assessment system has been developed to indicate pollution levels caused by easily degradable organic substances from sewers. The biotic index presented here is aimed at determining water's saprobic levels and was, therefore, named the "Saprobic Index for Brazilian Rivers in Minas Gerais and Rio de Janeiro states" (ISMR). For this purpose, saprobic valences and weights have been established for 122 taxa of tropical macrozoobenthos. Investigations were carried out in little, medium sized and big rivers in mountains and plains. Through ISMR, a classification of water quality and the respective cartographic representation can be obtained. Data collection and treatment methods, as well as the limitations of the biotic index, are thoroughly described. ISMR can also be used as an element to establish complex multimetric indexes intended for an ecological integrity assessment, where it is essential to indicate organic pollution.

    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.

    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 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

    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

  11. Hematite from a mining area in the east border of Quadrilatero Ferrifero, Minas Gerais, Brazil

    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.

  12. 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)

    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.

    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 Phenological studies are important to understand the dynamics in forest ecosystems and also to enable adequatemanagement of their native species. In the Cerrado regions of the high Rio Grande river (south of Minas Gerais State, Caryocarbrasiliense species is found in highly distinct morphological forms with variable phenology. The aim of this study was to investigatephenological patterns within and between populations of both the tree and shrub forms of the individuals and to determine anycorrelation with abiotic factors. Thirty-five observations of the phenophases of the vegetative and reproductive stages were recordedevery two weeks for 18 months. The activity index was analyzed for each stage and further analyzed to see if there were associationswith the climate data by using Spearman s linear correlation. The species was deciduous but leaf growth became retarded during thedry season, at which point leaf flushing stopped and total leaf fall occurred throughout the rainy season. The flowering and the fruitproduction occurred in the rainy season. The reproductive phase can be either annual or sub-annual. The activity index showed highsynchronism within populations during the first flowering in all populations studied (> 80%. Flowering and mature fruits were highlysynchronized according to Spearman correlations. Tree and shrub individuals of C. brasiliense had very similar times for theirphenophases. The best period for collecting mature fruits in these regions is between February and March.

    Full Text Available In this work, the physiognomy Savannah (Cerrado, present in three regions of the São Francisco River Basin, in Minas Gerais State, was studied with the following objectives: to adjust and to select equations to estimate total volume and stem volume; to test the similarity among volumetric models; to show the behavior of the volume in the stem and branches of the tree, and to evaluate the bark percentage in each diametric class. For this, the rigorous scaling using the method of Huber was accomplished, in which the data base was composed by 497 trees, distributed in six diameter classes, inside the three study areas. The bark thickness at the heights of 0%, 25%, 50%, 75% and 100% of the commercial height was measured. The accuracy of the models was evaluated by the determination coefficient, standard error of estimate and graphic analysis of the residuals. To test model identity, the method used was the one developed by Graybill (1976. The models selected for all the tested variables were the ones of Schumacher and Hall and of Spurr, transformed in logarithm. According to the identity test of models, for all the tested variables, similarity exists among the areas 2 and 3. Regarding to the behavior of volume, it was observed that the smallest diametric classes possess larger stem volume than the branches and that there is also a tendency of decreasing the bark percentage with the increase of the diametric class for the three studied areas.

    Full Text Available This trial aimed to evaluate the Biological Forewarning System (BFS for controlling Yellow Sigatoka in Northern Minas Gerais, Brazil. 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.

    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)

    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.

    This article presents an analysis of the Minas Gerais State Hospital Foundation immediately after the introduction in its health services units in early 1993 of a new system of rewards for good performance and productivity, as a complement to salaried remuneration. Analysis was based on a cross-sectional study of changes in indicators of production and productivity in the Foundation during the 1992-1995 period. Data were obtained from hospitalization authorization forms, payment authorization guides, and bulletins from the Human Resource Administration. The strategy of conditional remuneration and incentives was adopted not only to step up production and productivity, but also to increase the employees' commitment to the institution. Analysis of the selected indicators appears to confirm other study results in that remuneration based on results (conditional incentives) leads to a positive change in the production level of services and productivity, even if it does not last for the long term. Study results also support the notion that such alternatives may be deliberately used as part of a more general strategy of organizational development and not only as an isolated element for concrete improvements in productivity.

    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 The development of urban areas results in changes of natural landscapes, including the creation of several artificial environments. Thus, many animals find new opportunities for survival in these areas. This study aimed to obtain information about the richness, composition, and frequency of occurrence of the trophic guilds of an urban avian community in Ipatinga city, Minas Gerais State, followed by a general description. Between August 2005 and July 2006, 81 days were spent in sampling. From the method of direct observation, 57 species were recorded. The richness estimate for the area was 74.86 species (Chao2. The number of species between rainy and dry periods did not differ (p>0.05. Trophic guilds remained with a ratio of relatively similar species throughout the year, with a predominance of the omnivores and insectivores. Species such as Pitangus sulphuratus, Furnarius rufus and Sicalis flaveola were favored in the open areas. Two exotic species, Columba livia and Passer domesticus, were abundant. These results emphasize the necessity of the existence of natural areas within the urban context, considering not only the protection of the wildlife, but also the improvement of the quality of life in the cities.

    Full Text Available Knowledge of the true amount of officially granted use of water and the spatial distribution of water usage in a watershed has become indispensable for the appropriate management of water resources. In this process, the use of indexes allows for the identification of possible water use conflicts. The objective of this study was to evaluate the indexes of conflict regarding water use in the management (icg and planning (icp of water resources in the Paraopeba River Basin, focusing on identifying possible water resource conflicts and on providing supportive information for the water management agency in Minas Gerais State. Besides the Digital Elevation Model (DEM for hydrological analyses to calculate the drainage area for every river segment, the official amount of granted water use and estimated river flows at watershed confluences was also needed. The results of the icg calculation demonstrated that in 22.7% of the analyzed river segments the use of water was higher than what is legally granted, and this indicates a potential conflict regarding water use. The icp analyses showed that in three river segments the use of water was higher than the long-term mean flow. The combined icg and icp analyses led us to conclude that in the water use conflict scenario the solution could be establishing an infrastructure that would allow a year-round increase in the availability of water to be granted.

The results showed that 219 fires were recorded, burning 415,572.50 ha. In the average, 10.43 fires occurred per year, resulting in 19,789.17 ha burned. Incendiaries caused largest fires regarding the affected area, followed by fires caused by debris burning and lighting, that is first in number of occurrences. Fires caused by incendiaries and the unknown causes were more frequent in August and September. Fires caused by lightings occurred mainly in October and February, and those associated to debris burning were concentrated in the month of July. The largest fires occurred in areas with steep slopes, while the fires smaller than 4.0 ha, occurred in flat or smooth areas. Most of fires that occurred during the study period burned up to 200.000 ha and the larger fires occurred in the park region where the IBAMA (Instituto Brasileiro do Meio Ambiente e do Desenvolvimento Sustentável already has the ownership or land control.

    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 OBJECTIVE: To investigate the relationship between food habits and risk factors for cardiovascular disease in schoolchildren of the city Ouro Preto, Minas Gerais. METHODS: A cross-sectional study was conducted in a population-based sample of 738 schoolchildren aged 6-14 years. A semi-structured questionnaire was used for collecting demographic, socioeconomic, biochemical, clinical, and anthropometric data. Food intake was determined by a food-frequency questionnaire. Food habits were evaluated according to the adapted Recommended Food Score. Multiple linear regression models were constructed to assess how food consumption was associated with cardiovascular risk factors. RESULTS: The schoolchildren presented a dietary pattern characterized by low consumption of healthy foods. Association of cardiovascular risk factors showed that the consumption of foods according to the adapted Recommended Food Score was negatively and significantly associated with tetrapolar percentage of body fat (p=0.030 and systolic blood pressure (p=0.049 in children aged 6-9 years. CONCLUSION: Children's dietary patterns proved to be an important determinant of some of the cardiovascular risk factors studied. Thus, food intake assessment is a primary tool for the prevention and early intervention on cardiovascular risk factors during childhood.

    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 Scientific investigations about crop water requirements are of fundamental importance to the irrigation process. The main objective of this paper is to analyze and to map water requirements of coffee crop in Minas Gerais State, Brazil. Potential evapotranspiration values (ET0 were estimated by the Penman-Monteith-FAO method, using daily data sets available for 42 National Meteorology Institute (INMET stations for a period of 17 years. The crop coefficient values (kc considered were extracted from literature. The results were analyzed by means of geostatistical tools. The theoretical semi-variograms were fitted by the Maximum Likelihood method, considering spherical, exponential and Gaussian models. The maps were created using the ordinary kriging method. In a general way, the results have showed that the coffee crop evapotranspiration (ETc presents high variability in Minas Gerais State. The largest variations, both spatial and temporal, have been observed in the northern part of the State. January and June, respectively, presented the highest and the smallest water requirements of coffee crop. Based on this, we can conclude that due to the coffee crop evapotranspiration (ETc data distinction in different regions of Minas Gerais, a good estimate of the ETc values for each locality will bring many benefits to the coffee growers regarding irrigation scheduling.O conhecimento de informações que expressam a demanda hídrica das plantas, é fundamental para a irrigação.

    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.

    Full Text Available A área do Retiro-Branco, de propriedade da Companhia Geral de Minas, subsidiária da ALCOA Alumínio S.A., foi minerada para a extração de bauxita de 1978 até 1981. Em 1982/1983, essa área teve seu processo de reabilitação implementado mediante a hidrossemeadura de gramíneas e leguminosas e o plantio puro de Mimosa scabrella Bentham. Em 1997 foi realizado o primeiro inventário da regeneração natural do Retiro-Branco, aravés da implantação de 19 parcelas permanentes para caracterização inicial do processo de sucessão natural. E em 2000 foi realizado o segundo inventário dessas parcelas para caracterizar o processo de dinâmica da regeneração, o objeto deste trabalho. O processo de dinâmica da regeneração natural foi caracterizado mediante análises quantitativas e qualitativas da distribuição diamétrica. Os estudos indicaram que o monitoramento mediante inventário florestal contínuo, com parcelas permanentes setorizadas, é uma ferramenta viável para avaliações da dinâmica da regeneração natural, rumo à compreensão dos caminhos da sucessão. Foi caracterizado o processo de estratificação da regeneração natural, em que as espécies pioneiras e clímax foram as principais componentes do estrato inferior e as secundárias, as principais componentes do estrato superior. O povoamento florestal do Retiro-Branco está sobre intensa atividade de estruturação, caracterizando o estágio inicial do processo de sucessão. As espécies secundárias são as de maior dominância nas maiores classes de altura e de diâmetro, sendo as principais responsáveis pela edificação do estrato superior. A prognose da distribuição diamétrica, realizada mediante o emprego da Cadeia de Markov, foi uma ferramenta de fácil implementação e que permitiu prever o caminho do processo de sucessão para o povoamento todo e para os grupos ecológicos de espécies, ampliando o entendimento dos mecanismos que regem o comportamento

    Full Text Available Rainfall erosivity and its spatial variability were studied for 54 pluviometric stations in Southern Minas Gerais State (48º00' - 44º00'W; 23º50' - 20º00'S, aiming to plan the land-use strategies. Therefore, erosivity factor was determined for the pluviometric stations, using long-term rainfall data sets obtained along with the Brazilian National Water Agency- ANA, which varied from 15 to 40 years. The monthly and annual erosivity indexes were generated using Fournier equation for Lavras, MG and the spatial distribution of rainfall erosivity was studied on the basis of geostatistical approaches considering only the distance which separates them, developing the isotropic experimental semivariogram. The semivariogram adjustment was done based on the Weighted Least Squares method and the spatial dependence degree. Once the structure and the semivariogram adjustment were defined, the ordinary kriging maps were created, providing erosivity spatial behavior in Southern Minas Gerais. It was observed that the Southern Minas Gerais presents high erosivity patterns, ranging from 5,145 to 7,776 MJ mm ha-1 h-1 year-1, in Ijaci (north of region and Itajubá (southern region, respectively. Besides, it was verified that the erosivity indexes are intensely influenced by the topography, associated with climatic conditions. Higher erosivity is connected to areas with a higher altitude, such as along the Mantiqueira Range Mountain, and on high plateaus and mountain ranges in the North-Central part of the region. The geostatistical approach using long-term rainfall data in Southern region of Minas Gerais state, which is a relatively heterogeneous region in terms of altitude, soil depth and slope, showed to be adequate to the proposal of this study.Foram estudadas a erosividade e sua variabilidade espacial para cinquenta e quatro estações pluviométricas do Sul de Minas Gerais (48º00' - 44º00'W; 23º50' - 20º00'S visando à implementação do planejamento

    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

    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 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.

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.

Foram registradas para o Parque um total de 60 espécies de mamíferos, distribuídas por 9 ordens, 24 famílias e 49 gêneros. De um esforço total de 64.300 armadilhas-noite, foram realizados 2.129 capturas de pequenos mamíferos não-voadores pertencentes a 20 espécies. Foram também capturadas 14 espécies de quirópteros, representando 12 gêneros e 4 famílias. Em 300 Km de censos diurnos repetidos nas áreas de mata nativa foram registradas 12 espécies de mamíferos de médio e grande porte, além de 14 outras observadas através de meios diversos. Estes dados reforçam a idéia que a mastofauna da Mata Atlântica é bastante diversa. O Parque Estadual Florestal do Rio Doce deve ser considerado como uma das principais áreas para a conservação de fauna desta região e sua proteção deve ser priorizada.

    Leishmaniasis is a complex of zoonotic diseases that are endemic to many Brazilian states. They are transmitted to the vertebrates by the bite of the hematophagous female sand fly (Diptera: Psychodidae) vectors. Despite the increasing occurrence of visceral and cutaneous leishmaniasis cases in large urban centers, their transmission continues to occur primarily in a wild environment and may be associated with professional activities, ecotourism activities, or both. This study investigates the ecological parameters of the sand flies present in Ibitipoca State Park, Minas Gerais, Brazil. During 2009, systematic collections of sand flies were made monthly using HP light traps installed at five sites, including three natural settings (a cave, riparian vegetation, and a rain forest), the tourist and researchers' accommodations, and a surrounding domestic livestock area. In total, 161 sand flies (seven species) were collected, the most abundant, particularly in the surrounding domestic livestock area, being Lutzomyia (Psychodopygus) lloydi (Antunes, 1937). Furthermore, a previously unidentified Lutzomyia (Sciopemyia) sp. was prevalent in the cave environment. There are no existing records of the occurrence of leishmaniasis in Ibitipoca State Park; however, the some species of the subgenus Psychodopygus are known vectors of Leishmania spp in Brazil. Hence, the presence of a species of this genus in areas surrounding the park may represent a risk to ecotourism and the local inhabitants. Our study shows the importance of regular monitoring of the various areas used by humans to determine the distribution and spread of sand fly vectors for preventive management to forestall potential risk to health and consequent effect on ecotourists.

    Full Text Available A simulation study was conducted to estimate the production costs of animals with different proportions of Holstein genes and annual return per cow in a herd from the northern region of Minas Gerais. Data from the zootechnical archive of Fazenda Queluz, Francisco Sá, MG, Brazil, comprising the period from 2007 to 2012 were used. The production system consists of crossbred Holstein x Zebu (HZ cows with a genetic composition ranging from 1/4 HZ to 7/8 HZ. Total revenue per animal, annual profit per cow and variation in profitability were estimated over the years according to genetic composition. The revenue from milk production was greater for 7/8 HZ cows, but the estimated annual profit per cow was only 7.75% of total revenue, followed by 3/4 HZ cows which also exhibited low profit (4.11%. The highest profit was observed for 3/8 HZ cows, followed by 1/4 HZ and 1/2 HZ animals. Inversion of the genetic composition of the herd was observed over the years. In 2007, 64% of cows of the herd were 7/8 HZ, while in 2012, 7/8 HZ cows had been replaced with 1/4 HZ, 3/8 HZ and 1/2 HZ animals, accounting for 90% of all genotypes. Despite the greater production of animals with a higher proportion of Holstein genes, the change to cows with a higher proportion of genes of dairy Zebu breeds increased profitability, a fact that might be attributed to the greater economic efficiency of this genotype.

    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.

    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 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 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.

    Full Text Available Introduction: Modifications in the Brazilian Unified Health System (SUS have led to a significant improvement in the national health indexes. However, some challenges still need to be faced, especially concerning SUS patients' access to high-quality laboratory support services.Objective: To evaluate the present status of laboratory services in SUS in 31 cities of Minas Gerais, Brazil, between 2008 and 2011.Material and method: This analysis was performed through data from the Information Technology Department of SUS (DATASUS and through interviews with local public health managers with structured questionnaires.Results: Among all the studied cities, 21 had their own laboratory, 90.2% of which were in precarious conditions, not meeting the requirements established by the legislation in force, and employing inappropriate procedures and techniques, in addition to using obsolete equipment. The range of available laboratory tests was limited, what demanded the services of supporting laboratories. None of the evaluated laboratories developed any systematic activity on quality management, including control of analytical quality, maintenance of laboratory equipment, calibration and performance evaluation of critical equipment, continuing education programs, and safety and biosecurity.Conclusion: The effective role of laboratory test results in medical decision is unquestionably impaired, risking the safety of SUS patients. The present work reveals the deficiencies of public laboratory services in Minas Gerais, and proposes a new management model, which is able to associate operational quality, technological development and optimization of human and material resources with higher productivity.

    Full Text Available This study was undertaken to identify the phlebotomine fauna and species abundance in domiciliary and peridomiciliary (hen-house and guava-tree environments, on a lake shore, a cultivated area of coffee and banana, and a forested area of Conceição da Aparecida municipality, southeastern the state of Minas Gerais, to provide information for the control and epidemiological surveillance of leishmaniasis in this area. 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.

    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.

    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.

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

    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.

    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.

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.

    Full Text Available A cobertura do solo é o fator de maior importância relativa no controle da erosão hídrica. 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.

    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.

    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) 13 refs.

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.

The tested tools were the Biosonics DT-X (Biosonics Inc. echosounder and the SonarLite (Ohmnex Ltda bathymeter, both coupled to a Differential Global Positioning System (DGPS to obtain thegeographic coordinates associated with the depth in each point. Lagoa Central is a small, shallow (Zmax < 7.5 m, with low relative depth values (Zr = 0.5% and concave. This makes the water body less prone to thermal stratification and more susceptible to eutrophication. Both investigated equipments demonstrated to be suitable for the survey, user-friendly, low-cost and with sub-metric accuracy.

Cinqüenta e seis estirpes de leveduras do gênero Candida e uma linhagem de Trichosporon loubieri foram isoladas. Candida albicans foi a espécie dominante (28,1% das cepas, seguida por Candida parapsilosis (19,3%, Candida catenulata (14,0%, Candida glabrata (14,0% e Candida tropicalis (8,8%. Infecções mistas foram detectadas em 29,8% das vacas levedura-positivas. Amostras positivas para leveduras foram predominantemente obtidas (84% de vacas com mastite subclínica. A baixa taxa de isolamento de leveduras sugere que estes microrganismos não são relevantes para mastite bovina na região estudada.The objective of this study was to report the frequency of intramammary infections by yeasts, in Minas Gerais State, from milk samples (n = 1710 collected in 40 dairy herds. Fifty six yeast strains of the genus Candida and one strain of Trichosporon loubieri were isolated. Candida albicans was the dominant species (28.1% of the strains, followed by Candida parapsilosis (19.3%, Candida catenulata (14.0%, Candida glabrata (14.0%, Candida tropicalis (8.8%. Mixed infections were detected in 29.8% of yeast-positive cows. The yeast infection was more frequent (84% in cows with subclinical mastitis. The low rate of isolation of yeasts suggests that these microorganisms are not relevant to bovine mastitis in the studied region.

  8. Arsenic accumulation by ferns from the Iron Quadrangle, Minas Gerais, Brazil

    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. After freeze dried, the samples were ground and sieved (0 -standardization method and the

    Full Text Available The frequency of bovine genital campylobacteriosis (BGC in 157 cows from nine herds from the microregion of Varginha - Minas Gerais - Brazil was evaluated. Farmers use either artificial insemination and natural breeding after two insemination procedures or natural breeding. The diagnosis of BGC was performed by the direct fluorescent antibody test (DFAT using vaginal mucus. 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 Brazil is going through a fast and intense process of population aging. It is estimated that 1% of elderly Brazilians are institutionalized. Despite investigative advances within the field of geriatrics and gerontology over the last decade, studies on long-stay institutions in this country are at an incipient stage and serious problems relating to quality of care are appearing. Through a qualitative, exploratory and descriptive approach, this paper investigates the social representations of employees of a long-stay institution in a municipality in the State of Minas Gerais, regarding violence at that institution. The data, from the interview transcript, were processed using content analysis. The interviewees made mention of violence and told of their sincere and deep experiences as victims. However, with regard to the elderly people, it was as if the violence always happened outside the walls, i.e. never inside the institution. Sometimes a veiled but undisclosed complaint was perceived.

    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.

    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.

  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)

  19. 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 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.

    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.

    Isolated left prefrontal, left squamosal and atlas of titanosaur dinosaurs are described and compared. They come from the Late Cretaceous Serra da Galga Member of the Marília Formation at the Serra do Veadinho region, Peirópolis (Uberaba County, Minas Gerais State, Brazil). Due to the sparse cranial elements of titanosaurs already known from Brazil, these specimens are noticeable to be presented. In addition, the atlas vertebra is described for the first time for Brazilian titanosaurs. The morphology of the cranial bones closely resembles lithostratian titanosaurs, such as Rapetosaurus, rather than basal titanosaurs. The atlas is similar to that of other titanosaurs, suggesting that the anatomy of this element seems to be more conservative than other vertebral elements, in which vertebral laminae play an important rule in titanosaur taxonomy.

    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)

    A survey was carried out with the purpose of evaluating the nutritional status of the population of Jequitinhonha Valley in regard to vitamin A deficiency and iron-deficiency anemia. A Program--"Programa de Combate à Hipovitaminose A e à Anemia Nutricional Ferropriva em Bolsões de Probreza de Minas Gerais"--is being implanted by the Instituto Nacional de Alimentacão e Nutriçao (INAN) aiming to the prevention of such deficiencies. A random sample of 2,357 children from the towns: Turmalina, Minas Novas and Capelinha (Vale do Jequitinhonha), Minas Gerais (1,604 living in the urban and 753 in the rural areas) was submitted to an eye examination. Blood was drawn from a random subsample of these children (157 from the urban area and 107 from the rural area), in oder to detect possible nutritional problems. The following results were observed (preschool and school children, respectively): 1. Hemoglobin: 23.9% and 20% of the population in the urban area, 34.6 and 18.2% in the rural area, had low and deficient values, respectively. 2. Hematocrit: 1.5 and 2.2% of the population in the urban area, 17.3 and 5.5% in the rural area, had low values. 3. Vitamin A: 8.9 and 4.4% of the population in the urban area, 5.8 and 0% in the rural area, had deficient values (less than 10 micrograms/dl); 26.9 and 31.1% in the urban area, 26.9 and 23.6% in the rural area, had low values (10-20 micrograms/dl). These results show the occurrence of nutritional anemia and vitamin A deficiency in the observed children. As to the eye examination this was performed in 2,357 children. A high incidence of conjunctival xerosis (3.16 and 6.04% in the urban area, 7.7 and 12.6% in the rural area, in preschool and school children, respectively), was detected. Five cases of conjunctival xerosis with Bitot spot (0.2%), corneal xerosis (0.08%) and kerotomalacia (0.04%) were observed.

The discoverers found in the city's region a large potential for the progress of their activities, either in agriculture or in cattle-breeding (OLIVEIRA, 2000. Even today, milk production plays an important role in family farming activities, which besides raw milk, provides curdal cheese, cottage cheese, and "bottled butter fat", which is manufactured with fat extracted from whey. Therefore, this study was conducted to analyze the fatty acid profile of "bottled butter fat" produced in Salinas, in the northern region of Minas Gerais , and also to analyze the ratio of saturated to unsaturated fatty acid of these butters. The fatty acid profile of the "bottled butter fat" was determined by chromatographic analysis, according to methodology advanced by Luddy et al. (1960, and later modified by Abreu (1993. Analysis of variance was applied for comparison of the averages by the Tukey test at 5% probability. The fatty acid profiles of all the "bottled butter fat" were found to be similar. The concentration of saturated fatty acids was higher than that of the unsaturated, with averages of 60,36% and 39,64%, respectively.A história econômica de Salinas apóia-se em grande parte na pecuária.

Grande parte dos seringais encontra-se em Latossolos extremamente ácidos com Al alto e N, P, K, soma de bases trocáveis e capacidade de troca de cátions baixos. Os teores de Ca e Mg variaram de médios a altos nos Latossolos e foram muito altos nos Nitossolos, correlacionando-se negativamente com a produção de borracha seca. A análise foliar detectou desequilíbrios nutricionais no que se refere aos baixos teores de N e K evidenciados pela correlação positiva significativa com a produção de borracha seca. A correlação significativa negativa entre a produção de borracha seca e os teores de Ca foliares, associados aos altos teores de Mg, sugerem a redução desses nutrientes nas adubações. Dos micronutrientes, apenas o Cu apresentou correlação positiva e significativa com a produção de borracha seca.The objective of this work was to evaluate the nutritional status of rubber tree plantations at Zona da Mata region, Minas Gerais State, Brazil, to contribute with fertilization programs. Soil class, fertility levels, nutritional state and production of dry rubber were determined in rubber plantations of the clone IAN 873. Most plantations occur over extremely acid Oxisols with high contents of Al and low values of N, P, K, sum of exchangeable basis and cation exchange capacity. Calcium and Mg contents varied from medium to high and showed negative correlation with dry rubber production. Plant analysis showed unbalanced contents of N and K with low values but positive and significant correlation with dry rubber production.

    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

    Full Text Available In the North of Minas Gerais the equineculture is an important activity because it corroborates the success in the breeding of beef cattle. The equine verminosis control in this region has not been applied considering the anthelmintic resistances of nematodes and this resistance has been observed in some equine herds in Brazil. The present study has the objective to evaluate the effectiveness of pyrantel pamoate and ivermectin association in mare verminosis in the North of Minas Gerais, during the peripatum. After fourteen days of the first faecal egg count (FEC and treatment of the animals with these respective bases, the FEC reduction test indicated 98.1% effectiveness and the coprocultures were negative. After the worm identification from the control group, was observed 30% of filariod worms of Strongyloides spp., 30% of the genus Haemonchus, 20% were worms of Cyathosminae, 10% of the genus Trichostrongylgys and 10% of the genus Oesophagodontus. The results observed suggest that the use of pyrantel pamoate associated with ivermectin was safe during the peripartum and efficient in the FEC reduction of naturally infected mares raised in pastures of the North of Minas Gerais.

    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

    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.

    Full Text Available O ICMS Ecológico, criado em 1991 no Paraná, surgiu da reivindicação dos municípios que sentiam que suas economias eram prejudicadas pelas restrições de uso do solo, originadas por serem mananciais de abastecimento para municípios vizinhos ou por integrarem Unidades de Conservação. Dessa forma, o poder público estadual sentiu a necessidade de reformular os critérios de distribuição do ICMS, favorecendo estes municípios com recursos adicionais. Em Minas Gerais, o ICMS Ecológico foi criado em 1995, através da Lei Robin Hood. No sentido de verificar o impacto desse instrumento, esse artigo teve como objetivo analisá-lo nas suas funções de compensação e incentivo aos municípios mineiros. Nesse sentido, foram calculados os índices consolidados de produção e de preservação para todos os municípios mineiros, e utilizou-se um modelo de dados em painel para verificar qual a relação entre a área protegida e o valor do ICMS Ecológico recebido através do subcritério Unidades de Conservação. Os resultados obtidos mostram que esse instrumento compensa a maior parte dos municípios, mas vem perdendo sua importância nos últimos anos. Quanto ao incentivo, o ICMS Ecológico realmente incentiva a preservação e a conservação do meio ambiente, pois há uma relação direta entre o montante recebido e o crescimento de áreas protegidas nos municípios mineiros.The Ecological ICMS was first used to distribute a share of the ICMS revenue in the Paraná state in 1991. This pioneer experience originated from counties' claims which argued that their economies were harmed by land use restrictions, mainly because they were watershed protection areas or their territory was part of a conservation unit. Responding to these claims, the state government changed the ICMS allocation criteria, favoring those counties with added funds. In the Minas Gerais state, the Ecological ICMS was implemented in 1995 with the "Robin Hood Law". The

    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 INTRODUCTION: A study on the phlebotomine sandfly fauna was carried out in an endemic area for American tegumentary leishmaniasis in the municipality of Governador Valadares, in the State of Minas Gerais, Brazil. METHODS: Captures were undertaken using HP light traps in four districts, on three nights per month, for one year (from January to December 2008. Correlations between climatic factors (temperature, relative air humidity and rainfall and the numbers of sandflies collected was observed. RESULTS: 5,413 phlebotomine specimens were caught and were identified as belonging to 12 species. Of these specimens, 2,851 (52% were females and 2,562 (48% were males. CONCLUSIONS: Lutzomyia intermedia predominated (29.9% of the species caught, thus suggesting that they were responsible for transmission of American tegumentary leishmaniasis, together with L. whitmani, which was also found in the area (4.3%. The presence of L. longipalpis (11.9%, the main vector for visceral leishmaniasis in Brazil, is an important finding, which makes rigorous entomological surveillance of the area necessary.

    Full Text Available A study of the phlebotomine sand fly fauna was carried out in an endemic area of American visceral leishmaniasis (AVL in the municipality of Porteirinha, in the Brazilian state of Minas Gerais. Captures were performed with CDC light traps in 7 districts, 5 days per month, during 2 consecutive years (January 2000 to December 2001. A total of 3240 sand flies were captured and identified. Sixteen species were found, among which 15 belonged to the genus Lutzomyia and one to the genus Brumptomyia. Lutzomyia longipalpis, a proven vector of AVL, was the predominant species (71.85% throughout the time period. The interference of climatic factors (temperature, humidity, and rainfall over the populational dynamics of the sand flies was determined. Statistical analysis of the data showed a significant correlation among the number of phlebotomine sand flies collected, rainfall, and humidity, whereas the effect of temperature was negligible, in that particular region. The amount of collected phlebotomine, the number of human cases, and the prevalence of canine AVL in the districts of Porteirinha are discussed.

    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.

    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 Forensic Entomology research has been concentrated in only a few localities of the "Cerrado" vegetation, the Brazilian Savannah. The present study had, as its objective, an examination of the diversity of arthropod fauna associated with the carcasses of Sus scrofa (Linnaeus in this biome. The study was conducted during the dry and humid periods in two Cerrado vegetation profiles of the State of Minas Gerais. The decaying process was slower and greater quantities of arthropods were collected during the dry period. Insects represented 99% of 161,116 arthropods collected. The majority of these were Diptera (80.2% and Coleoptera (8.8%. The entomofauna belong to 85 families and at least 212 species. Diptera were represented by 31 families and at least 132 species. Sarcophagidae (Diptera and Scarabaeidae (Coleoptera were the richest groups. Oxysarcodexia (Sarcophagidae presented the largest number of attracted species, however none of these species bred in the carcasses. The Coleoptera collected belong to at least 50 species of 21 families. Among these species, Dermestes maculatus and Necrobia rufipes were observed breeding in the carcasses. This study showed species with potential importance for estimating the postmortem interval (PMI, indicative of seasonal and environmental type located.

    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 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.

    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.

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 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 The Family Companies have an important role in national economies and, specially in the Brazilian one. However its importance and feasibility are questioned. Good part of such questionings has a focus on the managerial limitations often observed in the management of Family Organizations. As a consequence the search for solutions under the managerial scope is an urgent issue for the survival of Family Companies. Within the myriad of current organizational strategies, knowledge management has emerged as an important competitive differential. Following this track, the objective of this article was to verify how knowledge management (KM in a rentail Family Company in Minas Gerais (Brazil occurs. A qualitative case study was carried through, based on data obtained from observations and interviews with managers. The results led to KM’s practices (JÓIA and OLIVEIRA, 2007: exchange of knowledge in meetings, study groups, incentive to innovation and dissemination of knowledge by personal contact. The conclusion highlighted how much the company’s environment favored KM’s practices due to the a favorable field for the development of innovation, creativity and sharing of implicit knowledge.

    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 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.

    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

    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%.

    Observational study that examined the quality of the preventive actions for schistosomiasis control in the Brazilian Family Health Strategy (FHS) in an endemic area. Structured questionnaires were used to interview 97 health professionals of the FHS and the Secretary of Health of 25 municipalities belonging to the State Health Department of Pedra Azul, Minas Gerais, Brazil. Models of latent variables were used to define a score to evaluate the quality of the process. The results showed that 57.8% of the FHS teams' actions were unsatisfactory or critical. The professionals did not perform effective activities for the control of the infection and 8.1% did not use the diagnostic methods required by the government. Similarly, the professionals did not receive adequate training for the development of schistosomiasis prevention and control. There was a lack of educational materials to carry out health education activities, and the FHS teams conducted educational activities in only 48% of the schools of municipalities. Less than half of the professionals interviewed knew about the Schistosomiasis Control Program. We concluded that it is necessary to integrate this Program's practices to the FHS, and seek a suitable support of municipal management through pacts and social control. PMID:27532760

    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 aim of this study was to determine the occurrence of intestinal parasites and commensals among children in four peripheral districts located in the northern, southern, eastern and western sectors of Uberlândia, Minas Gerais, using the Baermann methods as modified by Moraes and Lutz. Out of 160 individuals studied, 93 (58.1% CI: 50.4-65.7) were infected, distributed among the sectors as follows: northern (72.5%), southern (47.5%), eastern (57.5%) and western (55%). The positive findings according to age groups were: 0-5 years (26.9%), 5-10 years (21.2%) and 10-15 years (10%). Male children presented 2.7 times higher risk of infection than females did (OR: 2.7; CI: 1052-7001). The parasites and commensals identified were: Giardia lamblia (27.5%), Entamoeba coli (20.6%), Ascaris lumbricoides (14.4%), Enterobius vermicularis (8.8%), Hymenolepis nana (7.5%), Hymenolepis diminuta (5%), hookworms (3.1%), Trichuris trichiura (2.5%), Endolimax nana (2.5%), Entamoeba hartmanni (2.5%), Strongyloides stercoralis (1.3%), Iodamoeba butschlii (1.3%) and Capillaria hepatica (0.6%). The infection rate in these children was high and showed the need to implement prophylactic education programs in the community. PMID:19142436

    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

    Full Text Available From August 1999 to January 2000, samples of house dust were collected from 160 domiciles in the city of Juiz de Fora, State of Minas Gerais, Brazil. In 36 of these domiciles kitchen samples were obtained. Prevalence rate was 77.5%, varying according to the geographical sector. There were found 2,278 specimens of mites, with 1,530 (67.2% in the adult stage and 748 (32.8% in immature forms. The main species found were Dermatophagoides pteronyssinus, D. farinae, Euroglyphus maynei, Blomia tropicalis and Tyrophagus putrescentiae. In a minor incidence we found Lepidoglyphus destructor, Suidasia pontificiae, Chortoglyphus arcuatus, Cheyletus malaccensis, C. fortis, Ker bakeri, Cheletonella vespertilionis, C. caucasica and others. C. vespertilionis and C. caucasica were identified for the first time in the domiciliary ecosystem and in Brazil. The abundance rate and the infestation intensity were analyzed. There was a varied correlation between climatic conditions and positive domiciles and number of mites. The difference between the number of positive domiciles in the urban area and in the expanding urban area was significant and so was the difference between samples from the domiciles compared to those from the kitchens.

    Full Text Available Nursing assistance systematization is a scientific method with the aim of identifying and solving the clients’ health problems. The goal of the study was to evaluate the use of systematic nursing assistance for diabetic patients in two Family Primary Care Health Unities and in a General Hospital of Coronel Fabriciano, Minas Gerais state, Brazil, during the year of 2005. A retrospective and documental study was carried out by gathering the information contained in medical records of 45 patients, 15 interned and 30 followed-up at the Primary Care Health Unities. The obtained data were divided according to the stages of nursing assistance systematization: case history, diagnoses, care plan, implementation, and nursing evaluation or evolution. The results indicate that in the studied sample, the nurses incompletely registered their health actions and did not use nursing assistance systematization. It is worth to point out the need of stimulating the assistance systematization and the registering of control actions, prevention of complications, treatment and evolution of the Diabetes by the nursing team, aiming at increasing the quality of the rendered assistance.

    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)

    SUMMARY 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.

    This article summarizes the findings of a survey including 5,981 students from public schools in Minas Gerais State, Brazil. The analysis assessed the influence of drug use on sexual practices. Among the boys engaged in relationships with casual partners who stated having used illicit drugs, 55.7% reported consistent condom use, as compared to 65.4% among those not reporting such habits. Among boys engaged in relationships with stable partners who reported illicit drug use, consistent condom use was reported by 42.7%, versus 64.1% among those not reporting such habits. In the subgroup of boys engaged in stable relationships who did not report illicit drug use, consistent condom use was less frequent among those that used alcohol/cigarettes, compared to those who did not drink or smoke (60.7% vs. 71.1%). Girls were less likely than boys to use condoms consistently, regardless of the nature of their relationships, without a noticeable influence of drug use. Policies to prevent drug abuse, sexually transmitted diseases, and unplanned pregnancy should be fully integrated.

    The knowledge of the climatic conditions of a region is crucial for its agricultural development. It is also extremely important for understanding the fact that certain cultures have to develop under prevailing temperature and humidity conditions and assist in the adoption of a suitable irrigation technique, as well as its management and operationalization. The Köppen system of climate classification is widely used for the identification of homogeneous climate zones as it considers only rainfall and temperature as the meteorological elements for classification. For this study, we used climatic databases of rainfall and temperature in a raster format, with a spatial resolution of 30″ of arc (an approximate area of 0.86 km2 pixel-1), from 1961 to 1990. Through geoprocessing techniques, we obtained a map of climatic classification for the state of Minas Gerais. We found that the state has the following three major climatic groups: A, B and C, which correspond to tropical rainy, dry and warm temperate climates, respectively. The climate classes obtained were Aw, Am, BSh, Cwa and Cwb, with Aw, Cwa and Cwb classes occupying 99.89% of the territorial area of the state. The validation of the results showed a satisfactory agreement, with 93.75% reliability.

  20. 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

  1. Genetic similarity among Agistemus pallinii Matioli et al (Acari: Stigmaeidae) found in citrus orchards in Vicosa, Minas Gerais state, Brazil

    International Nuclear Information System (INIS)

    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 μm 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)

    2012-11-01

    Full Text Available This study aimed to evaluate the occurrence of schistosomiasis in areas with low endemicity using polymerase chain reaction (PCR as a diagnostic method. We analysed faecal samples from 219 individuals residing in Piau and Coronel Pacheco, state of Minas Gerais, Brazil, using a single faecal sample from each individual and two slides of the Kato-Katz technique as a gold standard. Fifteen out of the 219 samples were positive with both methods of diagnosis. One sample was diagnosed as positive by the Kato-Katz technique only and 61 were diagnosed only by PCR. The positivity rates were 7.3% with the Kato-Katz method and 34.7% with PCR. When both techniques were assumed to have 100% specificity and positive individuals were identified by both methods, the sensitivity of the Kato-Katz method was 20.8% and the PCR sensitivity was 98.7%. The Kappa index between the two techniques was 0.234, suggesting weak agreement. The assessment of a single faecal sample by PCR detected more cases of infection than the analysis of one sample with two slides using the Kato-Katz technique, suggesting that PCR can be a useful diagnostic tool, particularly in areas with low endemicity.

  4. Distribution of rare earths, thorium and uranium in bryophytes and soils in Tripui Ecological Station, Minas Gerais, Brazil

    International Nuclear Information System (INIS)

    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 k0-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.

Os resultados da pesquisa evidenciam que a orientação por resultados já se encontra incorporada nos discursos das Oscips, mas também destacam alguns paradoxos discursivos relativos à centralidade do novo papel do Estado vis-à-vis a crítica das suas estruturas burocráticas.The central aim of this paper is to present the results of a research that evaluated one of the components of the 'management shock' adopted by the government of the state of Minas Gerais: the partnership contracts sealed with the Oscips. Defined as an integrated set of development-oriented public management policies, 'Management shock' is a results-driven management model based on several contracting practices. The field research carried out over 2007 verified how the responsible for contracting (government and implementing (Oscips the services established in the main partnership contracts with the government of the state of Minas Gerais understand and justify the results

  6. 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. Os mesmos desconhecem o papel da equipe multidisciplinar na recuperação e reabilitação precoces.A stoma can be a serious limiting factor in the quality of life of people forced to live with it.

    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 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.

Clinicamente os animais apresentavam apatia, mostravam dificuldade respiratória durante dois ou três dias ou morriam subitamente. À necropsia as alterações pulmonares eram similares em todos os ovinos. Havia consolidação dos lobos craniais e da parte ventral dos lobos caudais e ao corte fluía exsudato mucopurulento da traquéia e dos brônquios. No parênquima dos lobos craniais havia áreas brancas multifocais a coalescentes com 0,2-0,5cm de diâmetro, levemente proeminentes e intercaladas por áreas vermelho-escuras. Pleurite fibrinosa foi observada nos Ovinos 1, 2 e 3. As lesões de consolidação ocupavam cerca de 70-80% da extensão pulmonar. Microscopicamente, as alterações eram de broncopneumonia fibrinopurulenta com intensa hiperemia, áreas com hemorragia intra-alveolar e espessamento dos septos interlobulares por inúmeros neutrófilos, restos celulares e intensa exsudação de fibrina. Áreas multifocais com necrose de liquefação contendo numerosas colônias bacterianas foram observadas no Ovino 3. Nos lobos craniais dos Ovinos 1, 2 e 3, haviam áreas com neutrófilos degenerados formando aglomerados de células alongadas com formato de "grãos de aveia" associados a colônias bacterianas. As alterações histológicas foram características de pneumonia causada por Mannheimia (M. haemolytica. Amostras dos lobos craniais de todos os ovinos foram encaminhadas para cultivo bacteriológico e M. haemolytica foi isolada e identificada em todos os animais.

    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. Os dados foram analisados usando-se o programa Epi Info versão 6.04. A amostra consistiu de 76,16% mulheres e 23,84% homens, com média de idade de 43,06± 14,65. A mutação fator V Leiden foi observada em heterozigose em 7,52% dos indivíduos e em 0,36% em homozigose. A mutação G20210A no gene da protrombina apresentou-se em heterozigose em 5,90% dos indivíduos e em homozigose em 0,18%. O presente trabalho mostra a importância dos testes genéticos conforme o perfil da população analisada, ressaltando informações epidemiológicas da população brasileira e benefícios clínicos.Thrombosis is known to be a multifactorial disease. Its incidence is directly related to the presence of genetic and acquired factors that concur separately or in association to its appearance.

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.

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.

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 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.

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.

    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

    Full Text Available INTRODUCTION: Infection by Neisseria meningitidis, termed as meningococcal disease, can cause meningococcal meningitis and septicemia with or without meningitis. Meningococcal disease is endemic in Brazil and has a high potential to cause large-scale epidemics; therefore, it requires the immediate notification of cases to the Information System for Notifiable Diseases (SINAN in Brazil. The aim of this study was to describe an epidemiological profile using data from notified and confirmed cases in the State of Minas Gerais, Brazil, from January 2000 to December 2009, obtained from the investigation records of individuals with meningitis registered with SINAN. METHODS: This was a retrospective, population-based study. Descriptive analysis of the data was made using the simple and relative frequencies of the categorical variables in the investigation records. RESULTS: There were 1,688 confirmed patients in Minas Gerais of which 45.5% lived in the Central, North, and Triângulo Mineiro regions. The highest frequencies of cases were in the 1-4-years age group (26.3%, males (54.7%, caucasian (36.4%, and lived in an urban area (80%. In the patients with specified education, 650 (60.9% patients had secondary education.

The present study aimed to lift the history SISVAN in Brazil and their situation in Minas Gerais and describe the nutritional status of children 0-5 years old accompanied by the system according to the W / A ratio and BMI / I. This was cross sectional study involving all children accompanied by SISVAN attended at primary health care in 2012 in the state of Minas Gerais, Brazil. Of the 469 265 children evaluated and monitored by Web - SISVAN according to the index weight x age, 3.8 % have low and very low weight for age, 87.3 % had normal weight and 8.8 % are with high weight for age. As for the other parameters, 7.5 % are malnourished, 60.3 % normal weight, 17.4% at risk of overweight and 14.8 % overweight. Therefore, we can say that the more nutritional deviation found in the population in 2012 was accompanied by overweight and obesity profile also already found in other studies. Thus, the majority of the population needs intervention through welfare programs and public health, as in tracing the nutritional profile of children of Minas Gerais, the data serves as input for the start of implementation of actions to promote health and baseline for monitoring trends of underweight and overweight in this group.

    O estado de Minas Gerais, atualmente, atua no sentido de regionalizar e descentralizar o setor de turismo, integrando diversos municípios que possuem características em comum, por meio de circuitos turísticos. O presente estudo foi realizado com o objetivo de caracterizar a dinâmica entre os atores que compõem os circuitos turísticos de Minas Gerais. Na primeira etapa da pesquisa, foi realizada uma macroanálise dos circuitos mineiros, os dados foram obtidos por meio dos órgãos gestores dos circuitos turísticos. Na segunda etapa, foram realizadas entrevistas com os atores-chave da Secretaria de Estado do Turismo de Minas Gerais e da Federação dos Circuitos Turísticos de Minas Gerais que apareceram na primeira etapa, para aprofundar nas análises sobre o inter-relacionamento desses atores. Os resultados obtidos sugerem a existência de um novo ator que apresenta ter uma importância fundamental para os circuitos, como também os interesses comuns e conflitantes dos atores e seus espaços de negociação. Finalmente, considera-se que existem estratégias conjuntas entre os circuitos, mas que ainda são muito embrionárias e que a percepção de alguns atores sociais a respeito de redes é um tanto quanto superficial.

    Full Text Available The aim of this work was to study the yeast populations and the main hygienic-sanitary microbial indicators in water buffalo mozzarella produced and commercialized in Minas Gerais, Brazil. Forty-two water buffalo mozzarella samples were purchased from retail outlets in Belo Horizonte. In addition, five samples of consecutive starter cultures, curd before acidification, acidified curd and mozzarella were collected at an industry in the city of Oliveira. Only three of the five water samples analyzed were suitable for consumption according to Brazilian sanitary standards. Four milk samples were highly contaminated with fecal coliforms, and did not meet the minimal hygienic-sanitary standards according to Brazilian regulations. Only one sample of buffalo muzzarela purchased from retail outlets exceeded the limit for coagulase-positive Staphylococcus. Eleven samples showed counts of thermotolerant coliforms higher than5x 10³ CFU.g-1, but still lower than the maximum permitted by the Brazilian laws. Salmonella spp. and Listeria monocytogenes were not isolated. Debaryomyces hansenii, Candida lusitaniae and C. parapsilosis were the prevalent yeast species isolated from cheese. Among samples from the production stages, the acidified curd presented the highest numbers of yeasts, with C. catenulata being the most frequent species isolated. Some opportunistic yeast species such as C. guilliermondii, C. tropicalis, C. parapsilosis, C. lusitaniae, C. catenulata, C. rugosa and C. krusei occurred in the mozzarella cheese samples analyzed. The mozzarella cheese presented a low microbial load as compared to other cheese already studied, and the yeast biota included species typical of cheese and also opportunistic pathogens.

    Full Text Available El objetivo de este estudio fue evaluar la calidad del agua meteórica en la ciudad de Itajubá, ubicado en la parte sur de Minas Gerais, Brasil. Para ello, se realizaron la colecta y análisis de la calidad de las muestras de agua de lluvia después de escurrir sobre la superficie de tres tipos de materiales; amianto, zinc y cerámica. También se realizó una colecta directa para comparar los resultados y verificar los cambios en la calidad del agua. Se observó que la calidad del agua de lluvia varía en función del material a través en el cual fluye, alterando de esta manera los parámetros físicos-microbiológicos como el pH, dureza, alcalinidad, turbidez y el contenido de coliformes. Por lo tanto, el material de la superficie de los sistemas de colección de agua de lluvia puede modificar la calidad del agua, y el destino final de este tipo de agua. A pesar que las aguas meteóricas de Itajubá presentaron un bajo grado de contaminación, se concluye que el tratamiento de estas aguas deben prever la remoción de sólidos, el ajuste de pH y la desinfección, de esta forma, se estará obteniendo una alternativa ventajosa, sustentable y asequible de uso en época de escases hídrica.

The objective of this work was to evaluate the Chagas Disease Control Program (CDCP in Açucena and to offer suggestions for improving local epidemiological surveillance. Methods This study was conducted in three phases: I a serological investigation of schoolchildren aged 5 to 15 years using an enzyme-linked immunosorbent assay (ELISA test performed on blood collected on filter paper followed by ELISA, indirect immunofluorescence (IIF and indirect hemaglutination (IHA on venous blood for borderline cases and those in the gray zone of reactivity; II vector evaluation using the data obtained by local health agents during 2006-2010; and III examination by ELISA, IIF and IHA of serum samples from the inhabitants of houses where infected Triatoma vitticeps was found and evaluation of their knowledge about Chagas disease. Results Five individuals had inconclusive results in the ELISA screening but were seronegative for Chagas disease. The triatomine evaluation revealed the presence of three species: Triatoma vitticeps, Panstrongylus megistus and Panstrongylus diasi. Triatoma vitticeps was the most prevalent and widespread, with a higher (67% index of Trypanosoma cruzi flagellates and evidence of colonization. Most of the inhabitants of the infested houses recognized triatomines and had basic knowledge about Chagas disease. Conclusions Although T. vitticeps is not clearly associated with Chagas disease transmission, these results highlight the importance of maintaining CDCP in endemic areas and the need for greater emphasis on epidemiological surveillance, especially in areas with important vectorial changes or that have been modified by human intervention.

    Full Text Available A recent (November 2010 outbreak of infectious laryngotracheitis (ILT in a multi-age laying hen facility in Minas Gerais state, Brazil, is described. Previous ILT outbreak in laying hens was only notified in São Paulo state, Brazil, in 2002. In the outbreak described here, the affected population was approximately eight million hens, with flock sizes ranging from 100,000 to 2,900,000 chickens. The average mortality ranged from 1 to 6%, and morbidity was around 90% (most of the twenty seven farms of the area were positive for ILT virus. Three multi-age laying farms from one company were selected for this report. Clinical signs included prostration, dyspnea, conjunctivitis, occasional swelling of the paranasal sinuses and bloody mucous nasal discharge. Severely affected chickens presented with dyspnea, gasping and became cyanotic before death. At necropsy, these chickens had fibrinous exudate blocking the larynx and the lumen of cranial part of the trachea. In addition, conjunctivitis with intense hyperemia, edema and sinuses with caseous exudate were present. On histopathology, there were marked necrosis and desquamation of respiratory ephitelium and conjunctiva with numerous syncytial cells formation and fibrinous exudate. Moderate to marked non suppurative (especially lymphocytes and plasma cells infiltration in the lamina propria also was observed. Sixteen out of 20 examined chickens, eosinophilic intranuclear inclusion bodies were observed in the syncytial cells. The DNA extracted from larynx and trachea produced positive PCR results for ILT virus (ILTV DNA using formalin-fixed, paraffin embedded (FFPE samples. Amplicons from a small region of ICP4 gene were submitted to sequencing and showed 100% identity with ILTV EU104910.1 (USA strain, 99% with ILTV JN596963.1 (Australian strain and 91% with ILTV JN580316.1 (Gallid herpesvirus 1 CEO vaccine strain and JN580315.1 (Gallid herpesvirus 1 TCO vaccine strain.

  18. Hydric resources evaluation of the Guarani Aquifer System in the State of Minas Gerais Araguari municipality, Brazil

    International Nuclear Information System (INIS)

    The general objective of this project is to investigate the aquifers comprised by the Guarany Aquifer System that could eventually be found at the county of Araguari, State of Minas Gerais, Brazil. The main purpose of this investigation is to assist in the implementation of a comprehensive program for the management of the water resources in this region.The proposal can be justified by the fact that, being Araguari located at the north-northeast limit of the river Parana basin, at the plateau which separates the basins of rivers Paranaiba and Araguari, the town concentrates about 90% of the whole population of the county, and is totally supplied by groundwater from the upper formations (Serra Geral and, predominantly, Bauru). Data on these aquifers are scarce, and their intensive explotation has already given rise to conflicts amongst the several water users, such as public and private water supply companies, and industrial and agricultural sectors. Aiming at the evaluation of the groundwater fluxes behavior in the aquifers, as well as the evaluation of their vulnerability to human impacts, besides some other more specific goals, and taking into account two recent studies carried out in the region, a methodology was proposed for simultaneous approaches to the problem, involving from the establishment of a hydrogeological conceptual model to the elaboration/application of a mathematical model for simulation of the groundwater flux and the preparation of natural and specific vulnerability maps of the aquifer system, including the local water budget. The studies will be conducted by the application of classical hydrological and hydrogeological techniques, as well as by the application of nuclear (tracer) and isotopic techniques

    In many countries all around the world, there is an increasing tendency to replace surface drinking water by commercially available bottled mineral water from different springs for consumption purposes. These practices involve an increased risk of finding higher activities of natural radionuclides in such waters, predominantly of the uranium-radium decay series. Naturally occurring radionuclides such as {sup 238}U, {sup 226}Ra, {sup 222}Rn, {sup 210}Po and {sup 228}Ra are found frequently dissolved in water supplies and their concentrations vary over an extremely wide range. However, from the point of view of radiation hygiene, results of many worldwide surveys indicate that only {sup 222}Rn, {sup 226}Ra and {sup 228}Ra have been found in concentrations that may be of health concern. {sup 226}Ra and {sup 228}Ra are the most radiotoxic isotopes of radium due to their long half-lives, 1,600 and 5.75 years, respectively. Since their chemical behavior is similar to that of calcium, radium isotopes tend to accumulate mostly in the skeleton after ingestion. For the purposes of this study, samples of mineral spring water were taken in Caxambu, a thermal resort located in the extreme south of Minas Gerais, 370 km south of Belo Horizonte. Caxambu is renowned by its waterpark, which has twelve sources of mineral water already being used in treatment of stomach, liver and kidney diseases, between others. {sup 226}Ra activity concentrations varied from 83 to 3,599 mBq L-1, the highest value determined at Venancio spring. Activity concentrations of {sup 228}Ra ranged from 69 to 4,481 mBq L-1. {sup 228}Ra/ {sup 226}Ra activity ratios varied from 0.079 to 4.2. (author)

  1. Initial growth of leguminous trees and shrubs in a cut gold mined area in Minas Gerais State, Brazil

    International Nuclear Information System (INIS)

    In an opencast gold mining in Minas Gerais State, Brazil, leguminous trees and shrubs were used to revegetate an acid cut mined area. the substrate was high in pyrite content (3%) and received 50 cm of covered material in two layers: (1) insulating layer of 20 cm where clay or a mining refuse (MR) was used to prevent the pyrite oxidation, and (2) an upper layer with 30 cm formed by topsoil or topsoil + urban compost (3:1 v/v). After the application of the cover materials, planting holes were manually made spaced by 1 x 1 m. Each hole received limestone (100 g), rock phosphate (150 g), potassium chloride (45 g) and cattle manure (2 L). Fifteen leguminous species were planted an each plot (15 x 8 m), spaced by 1.0 x 1.0 m (one specie per row). Sixteen months after the planting the plants were evaluated and the results showed an effect of substrate on the plants survival, height, and diameter. The use of clay as insulating layer was better than mining refuse and the plants did not respond to the addition of urban compost to the topsoil. Among the evaluated species, Thephrosia sinapau, Erytrina verna, Dipterix alata and Stryphnodenadrum guyanensis showed a mortality rate of 100% after 16 months while Sesbania marginata, Acacaia holosericea, Mimosa pellita, Acacia crassicarpa, Acacia mangium and Acacia angustissima exhibited more adaptation capacity to the acid substrate. Analyses from the substrate showed higher exchangeable acidity (Al3+) for the plots receiving MR as insulating layer. This study has applications for the acid mine drainage from coal mines of Brazil

    The Acaiaca Complex (AC) is located in southeastern Minas Gerais state, and comprises felsic, mafic, ultramafic, and aluminous granulite as well as lower grade gneisses and mylonite. The complex is distributed over an area of ca. 36 km by 6 km, surrounded by amphibolite facies gneisses of the Mantiqueira Complex (MC). The discrepancy in the metamorphic grade between both complexes led to the present study aiming to understand the metamorphic history of the AC by means of geothermobarometry calculations and electron microprobe Th-U-Pb monazite dating. Estimates of the metamorphic conditions of the granulite based on conventional geothermobarometry and THERMOCALC resulted in temperatures around 800 deg C and pressures between of 5.0 and 9.9 kbar and a retro metamorphic path characterized by near-isobaric cooling. Part of the granulite was affected by anatexis. The melting of felsic granulite resulted in the generation of pegmatites and two aluminous lithotypes. These are: 1) garnet-sillimanite granulite with euhedral plagioclase and cordierite that show straight faces against quartz, and is the crystallization product of an anatectic melt, and 2) garnet-kyanite-cordierite granulite, which is probably the restite of anatexis, as indicated by textures and high magnesium contents. Th-U-Pb monazite geochronology of two granulite samples resulted in a metamorphic age around 2060 Ma, which is similar to the age of the MC registered in the literature. The similar Paleoproterozoic metamorphic ages of both complexes lead to the conclusion that the Acaiaca Complex may be the high grade metamorphic unit geochronological related to the lower grade Mantiqueira Complex.

    Full Text Available In order to produce useful knowledge to the initiatives of protection and management of forest fragments, more specifically for tropical dry forests which suffer with frequent anthropic activities, and due to the lack of specific studies, this article aimed describe the structure and the floristic similarity among three areas of dry forest with different management histories. The study was developed in Capitão Enéas municipality, Northern Minas Gerais, Brazil, where three fragments were evaluated, being one in regeneration for 30 years, another submitted to occasional fire and the third with selective cut in small scale. The sampling was developed through the point quarter method considering all the alive phanerophyte individuals with circumference at breast height (CBH > 15 cm. In the three fragments, 512 individuals, distributed in 60 species, 47 genera, and 23 families were sampled. The most representative families were Fabaceae (26, Anacardiaceae (4, Bignoniaceae (3 and Combretaceae (3. However, fourteen families were represented by only one species. Only eight species were common to all fragments - Myracrodruon urundeuva standed out with 26.9% of all sampled individuals - while a great number of species were exclusive of each fragment. The floristic and structural differences between the fragments are possibly related to the history and intensity of management in each area besides the topography variations and the presence or absence of limestone outcrops. These results show the importance of each fragment, indicating that the loss of anyone would cause negative impacts on the regional flora and consequently to the associated biodiversity.

    Full Text Available O objetivo deste estudo foi determinar a importância e os encadeamentos dos setores de produção e abate e processamento da cadeia suinícola em Minas Gerais, nos anos de 1980 e 1995, por meio dos índices de Rasmussen-Hirschman, do campo de influência e do índice puro de ligação (GHS. De acordo com os resultados, ambos os setores analisados foram considerados setores-chave com base apenas no índice de Rasmussen-Hirschman e no campo de influência, ou seja, apresentaram maior relevância quando considerados os seus impactos na demanda final e os seus poderes de encadeamento na economia. Apesar de não terem sido considerados setores-chave pelo GHS, os setores de produção e abate e processamento apresentaram grande potencialidade de impactos para trás. Em face desses resultados e dado que esses setores continuaram aumentando a sua participação na economia de Minas Gerais nos anos subseqüentes a 1995, tem-se indicação de que estes devam ter prioridade na alocação de recursos e na estratégia de promoções industriais por meio de políticas estaduais.The main objective of this study was to establish the importance and the enchainment of the production sector and butchery/making up sector of pork chain in Minas Gerais, in the years of 1980 and 1995, applying the Rasmussen-Hirschman index, the influence field index and GHS index. The results showed that both sectors were considered key sectors only by the Rasmussen-Hirschman index and the influence field index, i.e., they presented greater importance when observed its impacts on the final demand and its power of enchainment in the economy. Despite not being considered key sectors by the GHS index, they presented great potential of backward impacts. This result, and the fact that the participation of these sectors had been increasing in the Minas Gerais economy since 1995, suggests that those sectors the state policy makers need to give priority in resources allocation and in the

    The main object of this paper was to study the concentration of deuterium (D) and Oxygen-18 ({sup 18} O) in the rain and river waters from the States of Minas Gerais, Sao paulo and Parana. Monthly samples were prepared and analysed at the Centro de Energia Nuclear na Agricultura (CENA-ESALQ-USP) with the use of CH-4 ({sup 18} O) and GD-150 (D) mass spectrometers of Varian-Mat. In order to correlate the D and {sup 18} O of the rain water the equation {delta}D = 9.22 + 7.17{delta}18 was found. Considering the three equations separately it was observed that the parameter a = {delta}D -b{delta}18 increases from the South to the North. For the Piracicaba River (city of Piracicaba only), the D and {sup 18} O relationship was expressed by {delta}D = -10.98 + 4.88{delta}18. The States of Minas Gerais and Sao Paulo can be divided according to the weight-average concentrations ({delta}18 m%{sub 0}). This division is not possible from Parana. Considering the average from the weight average concentration (annually and summer) for the three States, the annual average (D and {sup 18} O) is slightly richer than the summer average, showing the importance of the amount effect, mainly for the States of Minas Gerais and Sao Paulo. The rivers studied had little variation in the {sup 18} O concentrations with no definite periodicity. The rivers from the North of Minas Gerais are slightly richer in {sup 18} O than the rivers from the South. The waters from Rio Grande in the South of Minas Gerais State are poorer in {sup 18} O than the water of the same river in the `Triangle`region. The {delta}18% {sub 0} data for the rivers Grande, Parnaiba and Parana are very similar, so there is no way to compute the contribution of the first and the second rivers in the formation of the third.

    Full Text Available A prevalência de diabetes vem aumentando mundialmente e, neste artigo, foram analisados alguns de seus fatores associados, focalizando o segmento de idosos residentes em Minas Gerais. Foi utilizado o método de estudo seccional, com dados da PNAD-2003, envolvendo amostra de 3.662 pessoas com 60 anos e mais. Os fatores associados foram organizados segundo os níveis individual e domiciliar/comunitário, e analisados por meio de cinco modelos de regressão logística multivariada. O primeiro modelo incluiu apenas variáveis mais distantes; as demais foram incluídas sucessivamente, de acordo com sua proximidade ao diabetes. No modelo final, a chance de ter diabetes foi maior para: os idosos residentes na área urbana em relação à rural; as mulheres versus homens; os hipertensos em relação aos não hipertensos; aqueles com doença do coração em relação aos sem doença do coração; pensionistas versus não pensionistas; sem instrução e com 1 a 3 anos de estudo em comparação aos com cinco anos ou mais de estudo. A chance foi menor entre aqueles em domicílios unipessoais versus os de mais de uma pessoa, com 70 a 74 anos versus 60 a 64 anos, com renda inferior a um salário mínimo e mais de 3 até 5 salários mínimos em relação àqueles com cinco e mais salários mínimos. A relação entre renda individual do idoso e diabetes indica a necessidade de estudos que investiguem o acesso dos idosos aos serviços de saúde e que influenciam a auto-referência à morbidade.La prevalencia de diabetes viene aumentando mundialmente, y en este artículo, fueron analizados algunos de sus factores asociados, focalizando el segmento de ancianos residentes en Minas Gerais. Fue utilizado el método de estudio seccional, con datos de la PNAD-2003, abarcando una muestra de 3.662 personas con 60 años y más.

    Full Text Available Este artigo analisa o serviço da inspeção técnica do ensino como estratégia de produção de um modelo escolar em Minas Gerais no âmbito da Reforma João Pinheiro. No processo de constituição de um sistema educacional pautado no referencial da pedagogia moderna, os inspetores técnicos se configuraram como modeladores do ensino e buscaram capacitar os professores para o adequado exercício de novos métodos, dando-lhes a ver, por meio de aulas exemplares, modos de praticá-los. Nessa conjuntura, o inspetor técnico atuava sobre a prática docente, a partir de um lugar de poder determinado, o lugar de um intérprete autorizado cuja ação visava a aproximar as práticas dos professores das regras estabelecidas na conformação de um determinado modelo escolar de educação em Minas Gerais.Palavras-chave: inspeção técnica do ensino, estratégias, modelo escolar.  Technical inspection as a teachers’ formation device: production strategy of a school model in the state of Minas Gerais AbstractThis article analyses the service of technical inspection as a production strategy of a school model in the State of Minas Gerais under the João Pinheiro Reform. Within the process of constitution of an educational system guided by the reference of modern pedagogy, the technical inspectors were education shapers, enabling teachers to the proper exercise of new methods, making visible through exemplar classes the correct way to practice these new methods. Under this perspective, the technical inspector acted on the teaching practice, from an established place of power, the place of an authorized interpreter whose action intended to harmonize the teachers’ practices with the rules determined in shaping of a certain school model in the State of Minas Gerais.Key-words: technical inspection of education, strategies, school model. Dispositivo de inspección técnica como la formación del profesorado: una estrategia para la producción de una

    Full Text Available Na localidade do Brejo do Mutambal, situado no município de Varzelândia (MG, área endêmica para leishmaniose tegumentar, foram realizadas capturas mensais sistemáticas utilizando-se armadilhas luminosas do tipo CDC durante o período de janeiro a dezembro de 2000. Foram capturadas 19 espécies de flebotomíneos, totalizando 6.756 exemplares. Lutzomyia intermedia (5,1%, L. migonei (0,4% e L. whitmani (0,1%, relacionadas com a transmissão de leishmaniose tegumentar, foram capturadas em número reduzido. Lutzomyia longipalpis foi a espécie predominante (34,8%, sugerindo também um risco de transmissão da leishmaniose visceral. A proporção de insetos capturados no peridomícilio foi de 91,7% enquanto no intradomicílio foi de 8,3%. A interferência de fatores climáticos (temperatura, umidade relativa do ar e pluviosidade sobre a dinâmica populacional de flebotomíneos foi avaliada.Between January and December 2000, systematic monthly capture of phlebotomine sandflies was undertaken by means of light traps of CDC type in Brejo do Mutambal, an endemic area for American cutaneous leishmaniasis located in the municipality of Varzelândia, State of Minas Gerais. Nineteen phlebotomine species were captured, totaling 6,756 specimens. The species correlated with ACL transmission were captured in low numbers, as follows: Lutzomyia intermedia (5.1%, L. migonei (0.4% and L. whitmani (0.1%. Lutzomyia longipalpis was the predominant species captured (34.8%, thus also suggesting a risk of visceral leishmaniasis transmission. The proportion of sandflies captured in areas surrounding homes was 91.7 % while 8.3% were captured inside homes. The interference of climatic factors (temperature, relative air humidity and rainfall on phlebotomine population dynamics was evaluated.

    Full Text Available Enteral diets constitute an excellent means for microbial growth due to its composition rich in nutrients and its time of exposure to room temperature during application. Among the pathogenic bacteria there is the Staphylococcus aureus that is an opportunist microorganism found in the humans’ mucous membrane (buccal, nasal and oral. Samples of enteral diet after application as well as of the environment used for the preparation of the diets, were collected in a public hospital in Minas Gerais and analyzed for the presence of S. aureus. The contamination by S. aureus was evidenced in 83% of the enteral diet samples. As for the environment, the values found were in conformity with APHA recommendation. The isolated strains were submitted to the evaluation of the resistance to different antibiotics. Resistance was observed for tetracycline (100%, erythromycin (90,9%, chloramphenicol (59,1%, estreptomycin (22,72%, penicillin 18,8%, vancomycin (13,63%, ampicillin (13,63%, amoxilin (9,09% and gentamicin (4,54%. Due to the versatility in the resistance development to several antibiotics the S. aureus survives in hospital environments and can be diffused among patients. Dietas enterais constituem um excelente meio para crescimento microbiano, devido à sua composição rica em nutrientes e ao tempo de exposição à temperatura ambiente durante a administração. Dentre as bactérias patogênicas que podem ser encontradas nessas dietas, cita-se o Staphylococcus aureus, microrganismo oportunista encontrado na microbiota da membrana mucosa (bucal, nasal e oral em seres humanos. Amostras de dieta enteral pós-administração e do ambiente utilizado para o seu preparo foram coletadas em um hospital público e analisadas quanto à presença de S. aureus. A contaminação foi evidenciada em 83% das amostras de dietas enterais, e, quanto ao ambiente, os valores encontrados se apresentam de acordo com a recomendação da APHA. As cepas isoladas foram

    Full Text Available O presente artigo analisa 23 processos disciplinares contra professores e professoras das escolas públicas primárias durante a segunda metade do século XIX. A instauração desses processos e as suas consequências serviram como ações disciplinares e disciplinadoras por parte do Governo Mineiro e, para tanto, este contava com uma série de regulamentos que prescreviam práticas de inspeção e códigos disciplinares de ordem moral e/ou pedagógica. A cargo dos membros que faziam parte da Comissão do Conselho Diretor do Governo Mineiro ficava a responsabilidade por averiguar e punir aqueles professores e professoras que cometiam infrações como, por exemplo, negócios estranhos ao magistério, desempenho insatisfatório do trabalho docente e práticas que, segundo a legislação, não condiziam com a moral exigida ao cargo. Quando comprovado o descumprimento da lei, o docente ficava sujeito a suspensão, remoção ou demissão do magistério.This article analyzes 23 disciplinary processes and its results which were used as disciplinary actions of the teacher´s work by the Government of Minas Gerais/Brazil in the primary school during the second half of the nineteenth century. Although some of those strategies were just attempts, the Government proposed many laws intending to control the teacher´s work in the whole province/state. The Director Council members had the function of investigating and punishing the male and female teachers who had done some labors that were different from the teacher´s work, they had an unsatisfactory performance of teaching and had some moral behaviors that were not suitable for the office. Through a disciplinary process, the Government had the criterion and large legislation that punished the teacher with a temporary stoppage without payment, with a cast out from his/her space or with the definitive loss of his/her permission to teach in primary schools.
