    The natural radioactivity in commercial marble samples of 6 quarries in 'Cachoeiro do Itapemirim' and 'Castelo' municipalities of the south region of Espirito Santo State, southeast Brazil, was determined from the 226 Ra, 232 Th and 40 K contents. In 'Cachoeiro do Itapemirim' municipality were assessed the localities of 'Alto Moledo', 'Baleeira', 'Alto Gironda' and 'Itaoca' and, in 'Castelo' municipality, was assessed the locality of 'Sao Cristovao'. Three samples of each quarry were sealed in standard 100-mL HDPE polyethylene flasks and stored in order to obtain secular equilibrium in the 238 U and 232 Th series. All samples were measured by high resolution gamma spectrometry after a 30-days ingrowth period. Preliminary results show concentrations varying from 1,0 +- 0,2 Bq.kg-1 to 6,5 +- 0,8 Bq.kg-1 for 226 Ra, from 1,5 +- 1,2 Bq.kg -1 to 3,2 +- 1,7 Bq.kg -1 for 232 Th and from 5 +- 4 Bq.kg -1 to 27 +- 5 Bq.kg -1 for 40 K.

    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 a nervous disease, still not clearly diagnosed, that suggests intoxication. These pathologies are mostly noted after floods. Instrumental Neutron Activation Analysis and was applied to determine several elements in environmental samples. The irradiation characteristics are chosen to determine the isotopes in the best conditions. In this work the INAA, was applied using the TRIGA Mark I IPR - R1 (CDTN/CNEN).. The obtained results show that the contaminated water, sediment and forage 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.

    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.

    Full Text Available ABSTRACT Hardier crops are needed in the arid regions of the Brazilian state of Minas Gerais, and annatto (Bixa orellana L. is a good candidate. Producers, however, do not know if their areas are suitable for its cultivation and so are not investing in its implementation. Agroclimatic zoning would provide guidance to the producers. Identifying potential areas for the production of this crop would thus contribute to the agroclimatic zoning of B. orellana in Minas Gerais. We collected data for air temperature and precipitation from 852 meteorological stations in the state to classify regions as suitable, marginally suitable, or unsuitable for the crop. Suitable regions had an air temperature between 22 and 27 °C and precipitation between 800 and 1600 mm.y-1. Marginally suitable regions had an air temperature between 22 and 27 °C and precipitation less than 800 mm.y-1. Unsuitable regions had air temperature less than 22 °C or greater than 27 °C. A geographic information system was used for the spatial interpolation of air temperature and precipitation for all meteorological stations using kriging. The agroclimatic zoning of annatto crops for Minas Gerais was obtained by interpolating the two maps, air temperature and precipitation. Minas Gerais has great potential for urucum production, and agroclimatic zoning enabled the classification of regions by climatic suitability. The northern, western, northwestern, and part of the eastern regions of Minas Gerais have favourable climates suitable for the cultivation of B. orellana.

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

    Minas Gerais started the development of the Minas Gerais Health Promotion Policy (POEPS-MG) based on the review of the National Health Promotion Policy (PNPS). This is a case report based on the documentary analysis of the material produced in the 38 workshops with a participation of 1.157 members across the State. The first workshop was intrasectoral and took place at the State Health Secretariat (SDH-MG). The second was an intersectoral workshop with the participation of several State Health Secretariats of Minas Gerais. The final workshop counted on the participation of State Regional Technical References. Another 35 workshops were developed in the 28 State Regional Administrations. Results were systematized and consolidated from the Analytical Matrix used in the PNPS, generating the base document of the POEPS-MG. It is important to highlight that, the specific regional requirements identified during the Policy's construction process reinforce the enriching moments of developing in an innovative, democratic and participative way actions that may provide some meanings to Health Promotion in the State of Minas Gerais. The State Policy seeks to bring life to the PNPS, adapting it to the reality of the territory and strengthening it - with the assurance of budgetary resources.

    Computed Tomography (CT) is the diagnostic imaging method most commonly performed today. It is a device that is undergoing a technological evolution and their quality control is sorely needed. The image quality evaluation process allow a better diagnosis and control of the patient dose received during image acquisition. The CT doses are higher than other X-ray examination techniques, like a conventional X-ray. Performance evaluation of computed tomography in Minas Gerais is not significant. Therefore, this work aims to analyze 20 CT equipment in Minas Gerais, with parameters according to the national regulatory agency (ANVISA - Agencia Nacional de Vigilancia Sanitaria) in twelve quality control tests. Sixty five percent (65%) of CT equipment evaluated showed excellent results and were not disapproved in any of the tests performed and 30% had failed in only one of the twelve tests performed. The worst result was found in the CT scanners in the test that evaluates the low contrast resolution, where 20% of CT showed non-compliance, followed by the test that evaluates the x-rays collimation beam, where 15% had failed. The tests allowed us to observe that the twenty computerized tomography equipment achieved a great pass rate. Considering that the evaluated CTs performed the quality control tests for the first time, it is concluded that the equipment used in clinics and hospitals are of good quality image and low radiation doses.

    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.

    2006-12-01

    Full Text Available The Zona da Mata region of Minas Gerais spreads throughout an area equivalent to 6,09% of the State, with a population of 2,029,168 inhabitants, distributed through 142 municipalities, of which 70,23% have less than 10.000 inhabitants and low levels of urbanization. Nowadays, the economy is equivalent to 8,37% of the State’s GDP and approximately 11% of the population. Zona da Mata displays low per capita income, and an economic performance that falls short to its great potentials. Besides, the ongoing economic stagnation together with the lowering of quality of life indexes have exacerbated intra-regional discrepancies. This work explores the geohitory of Zona da Mata Region of Minas Gerais, seeking for historical determinants of current socioeconomic conditions.

    The objective of the present study was to assess for Minas Gerais the cokriging methodology, in order to characterize the spatial variability of Thornthwaite annual moisture index, annual rainfall, and average annual air temperature, based on geographical coordinates, altitude, latitude, and longitude. The climatic element data referred to 39 INMET climatic stations located in the state of Minas Gerais and in nearby areas and the covariables altitude, latitude, and longitude to the SRTM digital elevation model. Spatial dependence of data was observed through spherical cross semivariograms and cross covariance models. Box-Cox and log transformation were applied to the positive variables. In these situations, kriged predictions were back-transformed and returned to the same scale as the original data. Trend was removed using global polynomial interpolation. Universal simple cokriging best characterized the climate variables without tendentiousness and with high accuracy and precision when compared to simple cokriging. Considering the satisfactory implementation of universal simple cokriging for the monitoring of climatic elements, this methodology presents enormous potential for the characterization of climate change impact in Minas Gerais state.

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

    With the reformulation of the CNEN-NN-3.05 standard in December 2013, Brazil's Nuclear Medicine (NMS) services have to perform a greater number of quality controls for SPECT and PET equipment. However, little is known about the reality of the quality control programs of these services regarding the application of the new standard. Thus, in this context, the objective of the present study was to evaluate the quality control program of MNSs in the state of Minas Gerais. All NMSs in the state of Minas Gerais were invited to participate in the project. Of these, 34.48% (20 facilities) agreed to participate in the project, 50.00% (29 facilities) did not respond to the invitation and 15.52%(9 facilities) declined their participation. Thus, as of November 2015, 20 SPECT and 2 PET/CT equipment were evaluated for the performance of the quality control tests recommended by the new CNEN standard. The phantoms required for the evaluation came from the Laboratory of Dosimetry and Quality Control of UFMG. Even with the deadlines set by CNEN for the implementation of the quality control program in the NMSs, more than 50% of the evaluated services did not implement the quality controls, and the absence of specific phantoms is the main reason for the failure. Among the problems found in the installations, the most critical were: collimators with no conditions of use in the clinical routine, linearity problems of the evaluated image and values of image uniformity superior to the limits of acceptance. Problems in the uniformity and linearity of the image found directly impacted the performance of other tests, such as spatial resolution, SPECT performance, among others. In a general way, the NMSs in the state of Minas Gerais evaluated with the present study are in clinical feasible conditions. (author)

    The Deciduous Complex that occurs in northern Minas Gerais State, Brazil, raises questions about the floristic affinities of these formations in relation to neighboring phytogeographical domains. Little is known about the identity of the seasonal forest formations that comprise this complex, or about its relationships to abiotic components, such as soils, topography and climate. This study aimed to recognize the patterns of floristic similarity of all studied fragments of dry forest of northern Minas Gerais with soil and climate attributes, based on the available database. Cluster analysis indicated the existence of two floristic groups that had clear associations with either the Koppen's BSh (semi-arid) or Aw (seasonal tropical) climates. Likewise, the subdivisions of these groups showed clear associations with the dominant soil classes in the region. The Red-Yellow Latosol is the dominant soil classes in the BSh climatic domain, seconded by alluvial areas associated with Fluvic Neosols. The Aw domain comprised a much varied set of soils: Nitosols, Argisols, Cambisols and Litholic Neosols, most derived from the Bambuí limestone/slate formation. The ecotonal nature of northern Minas Gerais State provides a complex interaction between the flora of neighboring phytogeographical domains. This, allied to pedogeomorphological factors, allowed a better understanding of the effects of late Quaternary climate changes for the Deciduous Complex evolution. We conclude that the Latosols under present-day semi-arid climates (BSh) are relicts of former wetter climates, during which humid forest (semideciduous) expansion took place. Later, these semideciduous forests were subjected to a much drier climate, when selection for deciduousness led to the present-days Deciduous Complex scenario.

    Full Text Available Brazilian spotted fever is the most common rickettsiosis in Brazil, most prevalent in the States of São Paulo and Minas Gerais. The aim of this study was to describe the epidemiological characteristics of Brazilian spotted fever in Minas Gerais from 2000 to 2008. Of the 132 cases of Brazilian spotted fever, 53 patients died, representing a case-fatality rate of 40.2%. Males predominated, with 78.8% of confirmed cases, and median age was 26.5 years. Absence of rash was associated with increased risk of death (p = 0.005. Greater Metropolitan Belo Horizonte, Rio Doce Valley, and Zona da Mata accounted for 70.6% of the cases, which occurred mainly from May to November. There was an increase in the number of cases, which could suggest an expansion of the disease, but probably resulted from an increase in the health system's diagnostic capacity and sensitivity. Despite this improvement, the case-fatality rate remains high and with no apparent tendency to decrease, thus indicating the need for improved prevention and patient care.

    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.

    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 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. The best models were SARIMA (2,1,1x(1,0,012, for Belo Horizonte; SARIMA (2,0,0x(2,1,212,for Divinópolis; SARIMA (2,1,1x(1,0,012, for Sete Lagoas and SARIMA (1,1,1x(1,1,112, for Vertentes. Such models presented in aparsimonious way, containing a small number of parameters. All models SARIMA (p,d,q (P,D,Qs, for the four studied areas,presented white noise and supplied adequate price forecast.

    Full Text Available A cross sectional study was performed to assess the epidemiological status of bovine tuberculosis in the state of Minas Gerais, Brazil, in 2013. The state was divided into seven regions, and a preset number of herds was randomly sampled in each region. From each farm, female cattle aged 24 months or older were randomly sampled and subjected to the comparative cervical tuberculin test (CCTT. Animals with inconclusive test results were re-tested with the same diagnostic procedure after a minimum interval of 60 days. A total of 31?832 animals were tested from 2?182 farms. An epidemiological questionnaire was administered in the farms to identify risk factors associated with bovine tuberculosis. Prevalence in the state was estimated at 4.25% (95% CI: 3.36% – 5.15% for herds and at 0.56% (95% CI: 0.46% – 0.66% for animals. Data on herd prevalence for bovine tuberculosis for each stratum showed the highest prevalences at region Sul e Sudoeste (stratum 5 and region Central (stratum 3 which were significantly different from the lowest prevalences found at regions Noroeste, Norte e Nordeste (stratum 1 and region Leste (stratum 2.

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

    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.

    Health education is a powerful tool that enhances social, economic and cultural contexts of the community, allied to the process of health promotion. The purpose of this study was to find the perception of nurses, related to the Family Health Strategy, on health education, in Uberaba, Minas Gerais State. It was a descriptive study, with a qualitative approach, using the method of thematic analysis. Semi-structured interviews were held with 20 nurses from Family Health Strategy (FHS) of that council. From the obtained information, five themes were abstracted: concepts; posture; bank education, professional growth; and occasional action. It was possible to identify that the subjects, in everyday life, have a wide perspective of health education, with a close relationship of professionals to this practice. However, workers still perceive this strategy in a vertical way, institutionalized, with a single-user sense of training. It is believed that this study could contribute to a discussion about the issue in practice, and thus enable the construction of a new look on health education, based on dialogical relations and the enhancement of popular knowledge.

    This study analyzed the association between self-reported diagnosis of hearing loss and individual and occupational factors among urban transportation workers in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. The sample size was calculated by quotas and stratified by occupation (drivers and fare collectors) in the urban transportation companies in Belo Horizonte, Betim, and Contagem. Data were collected with face-to-face interviews and recorded by the interviewers on netbooks. The dependent variable was defined as an affirmative response to the question on prevailing medical diagnosis of hearing loss. The independent variables were organized in three blocks: social and demographic characteristics, lifestyle, and work aspects. Diagnosis of hearing loss was reported by 213 of the 1,527 workers and was associated with age and diagnosis of tinnitus. At the occupational level, hearing loss was associated with history of sick leave, time-on-the-job, and two environmental risks, unbearable noise and whole-body vibration. Measures to prevent hearing loss are needed for urban transportation workers.

    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 Aiming of selecting generations of Arabic coffee plants adapted to different coffee regions of the state of Minas Gerais, experiments were conducted in the cities of Três Pontas, Campos Altos and Capelinha. Thirty three progenies from the “Mundo Novo” cv. were evaluated obtained by the genetic improving program of the coffee plants led by the Instituto Agronomico in Campinas. The experiments were carried out in randomized complete block design with four repetitions and six plants by parcel. The yield analysis were performed conjoint for the three sites and six crops. The adaptability and stability of the individual features were evaluated applying the methodology proposed by Annicchiarico (1992, estimating the Confidence Index (Ii and defining as environment the combination between each biennal and each place, that is, nine environments. The parameters fruit maturation stage, floating grains bean/ fruit and bean size were carried out considering the medium of the last two crops, in Três Pontas. The most promising are the IAC 2931, IAC 379-19, IAC 480, IAC 388-6-16 and IAC 379-19-2 because they showed higher stability in the environments and were among the most productive ones in the average of the nine environments, obtaining higher confidence indexes. The progenies IAC 515-8, IAC 501 12, IAC 464 15 have the best percentages of fruit maturation stage, floating grains bean/fruit and bean size.

    The organization of public clinical laboratories is experiencing changes without, however, an organizational assessment of its effectiveness. The study aimed to determine a parameter of effectiveness for public clinical laboratories of Belo Horizonte, Minas Gerais State, and set cut-off points for the sections of these laboratories. In order to do so, the total production and number of hours worked during a period of 7 months in the year 2008 were consolidated. Due to the entrance of the workers in the mode of production in the laboratories network, it could be observed a variability regarding the performance of these workers. The effectiveness parameter of the network was established in 29.90 tests per hour. As a consequence of this first analysis, the cut-off points are: 15.50 for the hematology section; 67.29 for chemistry; 6.45 for parasitology; 11.35 for urinalysis; 4.94 for microbiology and 19.03 for immunology. From these results, it was concluded that the working process in laboratories can generate a decrease in effectiveness.

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

    Full Text Available The main of the study was to evaluate the presence of Borrelia burgdorferi infection in domestic and wild vertebrates and ectoparasites in endemic areas from the state of Minas Gerais, Brazil. A total of 445 serum samples were examined by ELISA, which used the Borrelia burgdorferi strain G39/40 U.S. source and 3,821 tick samples were tested by polymerase chain reaction (PCR. B. burgdorferi antibodies were found in 30 serum samples (6.74%; three in marsupials (7.69%, three in rodents (2.80%, nine in dogs (6.25%, and 15 in horses (9.68%. Nested-PCR performed in DNA samples obtained from collected ticks demonstrated negative results. Although attempts to amplify B. burgdorferi DNA from ticks had been not successful, the presence of seroreactive vertebrates suggests the possibility the Borrelia species circulating in these regions. Further research is required to provide information on the presence of Borrelia in Brazilian territory and its association with Baggio-Yoshinari syndrome.

    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.

    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 One of the main arguments for the existence of public social security systems relates to their potential use as income distribution and welfare policy tools. In this vein, several studies have sought to evaluate the effects of social security benefits on poverty and inequality. However, the evidence obtained from Brazilian studies regarding the effects of social security remains inconclusive, and studies evaluating the impact of social security on social welfare indices are scarce. The objective of this paper is to measure the impact of retirement and pensions provided by social security programs on the welfare level of households in the state of Minas Gerais, Brazil. The methodological approach is based on propensity score matching, and microdata from the National Household Sample Survey (Pesquisa Nacional por Amostra de Domicílios - PNAD, 2009 are used. The results demonstrate that income from retirement and pensions represents an important portion of beneficiary households' income, especially lower-income beneficiary households. The results suggest that social security has a positive effect on the incomes, access to knowledge and living conditions of the households analyzed. The impact of retirement and pensions on households in low-income groups (Classes D and E tends to be more significant relative to the impact on middle class households (Class C.

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

    Full Text Available With the aim of studying the endoparasite fauna of horses from the Formiga city, located in center-west region of the state of Minas Gerais, 25 animals that were naturally infected with helminths were evaluated. By means of parasitological necropsies, different endoparasites were found. The subfamily Cyathostominae presented the highest incidence, followed by Trichostrongylus axei, Oxyuris equi, Triodontophorus serratus, Strongyloides westeri, Strongylus edentatus, Habronema muscae, Parascaris equorum, Probstmayria vivipara, Strongylus vulgaris, Gasterophilus nasalis, Anoplocephala magna and Anoplocephala perfoliata. In the present study, if the species Probstmayria vivipara was not considered in the prevalence, the frequency of Cyathostominae was equivalent to 94.85%. The results obtained in this study allowed us to detect and identify different species of helminths in horses, and confirmed the high incidence of nematodes belonging to the subfamily Cyathostominae in the center-west region of Minas Gerais.

    The main object of this paper was to study the concentration of deuterium (D) and Oxygen-18 ( 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 ( 18 O) and GD-150 (D) mass spectrometers of Varian-Mat. In order to correlate the D and 18 O of the rain water the equation δD = 9.22 + 7.17δ18 was found. Considering the three equations separately it was observed that the parameter a = δD -bδ18 increases from the South to the North. For the Piracicaba River (city of Piracicaba only), the D and 18 O relationship was expressed by δD = -10.98 + 4.88δ18. The States of Minas Gerais and Sao Paulo can be divided according to the weight-average concentrations (δ18 m% 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 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 18 O concentrations with no definite periodicity. The rivers from the North of Minas Gerais are slightly richer in 18 O than the rivers from the South. The waters from Rio Grande in the South of Minas Gerais State are poorer in 18 O than the water of the same river in the 'Triangle'region. The δ18% 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.

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

    Full Text Available Eleven species of tanagers in Ibitipoca State Park, Minas Gerais, southeastern Brazil, were studied for 12 months and the birds diet was described. 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.

    Telecardiology is a tool that can aid in cardiovascular care, mainly in towns located in remote areas. However, economic assessments on this subject are scarce and have yielded controversial results. To evaluate the cost-benefit of implementing a Telecardiology service in remote, small towns in the state of Minas Gerais, Brazil. The study used the database from the Minas Telecardio (MTC) Project, developed from June 2006 to November 2008, in 82 towns in the countryside of the state. Each municipality received a microcomputer with a digital electrocardiograph, with the possibility of transmitting ECG tracings and communicating with the on-duty cardiologist at the University hospital. The cost-benefit analysis was carried out by comparing the cost of performing an ECG in the project versus the cost of performing it by patient referral to another city. The average cost of an ECG in the MTC project was R$ 28.92, decomposed into R$ 8.08 for the cost of implementation and R$ 20.84 for maintenance. The cost simulation of the ECG with referral ranged from R$ 30.91 to R$ 54.58, with the cost-benefit ratio being always favorable to the MTC program, regardless of the type of calculation used for referral distance. The simulations considered the financial sponsor's and society's points-of-view. The sensitivity analysis with variation of calibration parameters confirmed these results. The implementation of a Telecardiology system as support to primary care in small Brazilian towns is feasible and economically beneficial, and can be used as a regular program within the Brazilian public health system.

    Studying the factors associated with the use of dental services can provide the necessary knowledge to understand the reasons why individuals seek out public healthcare services and the formulation of more appropriate public policies for the present-day reality. This work was a cross-sectional epidemiological study consisting of a sample of adults found in a research databank concerning the conditions of the oral health of the population of the state of Minas Gerais, Brazil. This study examined both main oral health disorders and relevant socioeconomic aspects. The dependent variable was defined as the type of service used, categorized under public and private use. The independent variables were selected and grouped to be inserted in the analysis model according to an adaptation of the behavioral model described by Andersen and Davidson. A hierarchical model was used to analyze the data. The description of variables and bivariate analyses were performed in an attempt to verify possible associations. For each group of variables at each hierarchical level, the gross and adjusted odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated by means of logistic regression. The Complex Samples model from the SPSS statistics program, version 19.0, was used to analyze the sample framework. In the final model, the factors associated with the use of public healthcare services by adults were directly related to the socioeconomic and demographic conditions of the individuals, including: being of a dark-skinned black race/color, belonging to families with more than four household residents and with a lower income level, residing in small towns, having more teeth that need treatment. According to the findings from this study, socioeconomic and demographic factors, as well as normative treatment needs, are associated with the use of public dental services.

    Full Text Available ABSTRACT: Macauba palm stands out for having favorable features to biodiesel production such as the high oil content of its fruit. Considering the great potential of the species and their applicability in the renewable energy field, it becomes indispensable to establish the right conditions for storing the seeds for propagation purpose. The aim of this research was to evaluate the effect of seed moisture content, packaging, and storage conditions such as temperature and relative humidity on the quality of seeds from Minas Gerais State, during a 12-month storage period. The research had two independent assays: (I the seeds were stored with three moisture contents/ranges 4.0≤6.0%; 6.0≤8.0% and 8.0≤10.0% in impermeable packages, under room temperature and at 10ºC; (II seeds with approximately 5.9% of moisture content were stored in three different types of packages: a permeable, b semi-permeable and c impermeable. Three storing conditions were tested: a room temperature and RH under laboratory conditions; b 15ºC and 45% RH; c 20ºC and 55% RH. Water content, germination rate and germination speed index were evaluated at 0, 4, 8 and 12 months of storing. The best germination results were obtained with the moisture range of 6.0≤8.0%, with seeds kept at room temperature; while the seeds stored at 10ºC, regardless the moisture range, did not survive. The stored seeds with 5.9% moisture content and at both 15ºC/45%RH and 20ºC/55% RH conditions, independently of the package type used, showed the best results. Thus, macaw palm seeds can be classified as intermediates seeds.

    Triatoma sordida and Triatoma pseudomaculata are frequently captured triatomine species in the Brazilian savannah and caatinga biomes, respectively, and in Brazilian domiciles. This study identified eco-epidemiological changes in Chagas disease in northern Minas Gerais state, Brazil, and considered the influence of environmental shifts and both natural and anthropogenic effects. Domicile infestation and Trypanosoma cruzi infection rates were obtained from triatomines and sylvatic reservoirs during the following two time periods: the 1980s and 2007/2008. Entomological and climatic data with land cover classification derived from satellite imagery were integrated into a geographic information system (GIS), which was applied for atmospheric correction, segmentation, image classification, and mapping and to analyse data obtained in the field. Climatic data were analysed and compared to land cover classifications. A comparison of current data with data obtained in the 1980's showed that T. sordida colonised domiciliary areas in both periods, and that T. pseudomaculata did not colonise these areas. There was a tendency toward a reduction in T. cruzi infection rates in sylvatic reservoirs, and of triatomines captured in both households and in the sylvatic environment. T. sordida populations have reduced in the sylvatic environment, while T. pseudomaculata showed an expanding trend in the region compared to counts observed in the 1980's in the sylvatic environment. This may be related to high deforestation rates as well as gradual increases in land surface temperature (LST) and temperatures along the years. Our results suggest a geographical expansion of species into new biomes as a result of anthropogenic and climatic changes that directly interfere with the reproductive and infection processes of vectors.

    To analyze the profile of claimants and medicines demanded in lawsuits. Descriptive study that examined 827 lawsuits with 1,777 demands of access to medicines in the period between July 2005 and June 2006 in the state of Minas Gerais, Southeastern Brazil. There were examined the type of health care provided to claimants and their attorneyship. The medicines were described based on the following: drug registration at the National Health Surveillance Agency (Anvisa); wheter they were essential medicines; supply in the Brazilian Health System programs; and evidence of drug efficacy. More than 70% of the claimants were provided care in the private health system and 60.3% hired private lawyers. The most common diagnosis of claimants was rheumatoid arthritis (23.1%) and the immunosuppressant agents were the most frequent demand medicines (mainly adalimumab and etanercept). Approximately 5% of the medicines demanded were not registered at Anvisa, 19.6% were included in the Brazilian List of Essential Medicine, 24.3% were included in the High-Cost Drug Program and 53.9% showed consistent evidence of efficacy. Among the medicines that were not available in Brazilian Health System, 79.0% had therapeutic alternatives in drug programs. The phenomenon of judicialization of health in Brazil can point out failures in the public health system as some medicines demanded are included in its lists. However, it is a barrier for rational drug use and application of the National Drug Policy guidelines, especially when there are demanded medicines with no evidence of efficacy and that are not included in Brazilian Health System standards.

    Full Text Available OBJETIVO: Descrever comportamentos facilitadores à exposição ao HIV/Aids em população rural. MÉTODOS: Pesquisa qualitativa realizada com 52 pacientes atendidos em ambulatório de DST/Aids, em 2002-2003. 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.

    To analyse the clinical and epidemiological profiles of dengue haemorrhagic fever (DHF), dengue shock syndrome (DSS) and complicated dengue cases and deaths from 2008 to 2010 that occurred in the state of Minas Gerais, south-eastern Brazil, and to identify factors associated with death from dengue. Historical cohort study using data from the Brazilian Information System for Notifiable Diseases. A descriptive analysis of the DHF, DSS and complicated dengue cases and deaths was performed; the incidence, mortality and case-fatality rates were estimated. Logistic regression analysis was used to identify factors associated with death from dengue. Comorbidities were not included in the analysis because the information system does not contain such data. During the study period, 2214 DHF, DSS and complicated dengue cases were reported, including 156 deaths. The annual case-fatality rates for DHF/DSS and complicated dengue cases in the period of 2008-2010 were 7.3%, 4.8% and 7.9%, respectively. The factors associated with death from dengue included residence in a municipality with a population of fewer than 100,000 inhabitants [odds ratio (OR) 2.46; 95% confidence interval (CI) 1.71-3.55], age over 65 years (OR 3.05; 95% CI 1.99-4.68) and plasma leakage (OR 1.69; 95% CI 1.16-2.46). The results support the importance of plasma leakage as a warning sign associated with death from dengue as well as the signs and symptoms that allow the diagnosis of DHF. Moreover, our findings suggest that increased attention is necessary for individuals over 65 years of age and in municipalities with populations under 100,000 inhabitants to ensure a better quality of care during the management of severe patients of dengue in these locations. Differences in the interpretation of the DHF definition have hindered the comparison of data from different countries; it can improve from the WHO 2009 dengue classification. © 2014 John Wiley & Sons Ltd.

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

    Full Text Available ABSTRACT: A survey of veterinary drug residues in bulk milk tank from Minas Gerais State, Brazil, was carried out through a broad scope analysis. Here, 132 raw milk samples were collected at 45 dairy farms in Minas Gerais from August 2009 to February 2010, and analyzed for 42 analytes, comprising pyrethroids, macrocyclic lactones and antibacterials, using liquid chromatography coupled with mass spectrometry in tandem mode and gas chromatography with electron capture detection. Within all milk samples, at least one veterinary drug residue was identified in 40 milk samples (30.30% by confirmatory tests, whereas 16 samples (12.12% showed the presence of at least two residues. With regard to the Brazilian maximum residue levels, 11 milk samples (8.33% were non-compliant according to Brazilian Legislation. The veterinary drugs detected in the non-compliant milk samples include penicillin V (one sample, abamectin (one sample and cypermethrin (nine samples. Furthermore, the antibacterial screening methods failed to identify most of the positive samples that were detected by confirmatory tests, leading to a large discrepancy between the screening and confirmatory antimicrobial tests. Thus, the present study indicated that the veterinary drugs residues still represents a great concern for the milk production chain.

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

    Leptospirosis is an infectious and acute disease caused by Leptospira spp. that have high epidemic potential. This study verified the main Leptospira spp. serovars detected by MAT from serum of patients with suspicion of leptospirosis from 2008 to 2012 in Minas Gerais State. The laboratory received sera from 4654 patients. All serum were screened by IgM-ELISA according to the manufacturer's instructions. Each sample reactive or indeterminate were tested against twenty-four serovars of Leptospira by MAT. In this study, 597 patients were classified as reactive on MAT. Only 301 patients were confirmed by laboratory test. It was not possible confirmation by laboratory diagnosis of 296 patients. Among the samples classified as reactive on MAT, 273 patients exhibited titers bigger than 800 for one or more serovars; seroconversion was detected in 28 cases. Percentage of 85.1% of the samples reactive on MAT corresponded to males, 39.4% corresponded to patients aged between 20 and 39 years old. The most common serovars found were Icterohaemorrhagiae, Andamana, Patoc, Tarassovi, Copenhageni, Hardjo and Australis. Concerning the samples that exhibited titers bigger than 800, serovar Icterohaemorrhagiae was also the most common, followed by Copenhageni, Andamana, Patoc, Tarassovi, Grippotyphosa and Canicola. In this study, 40% of the cases occurred to the metropolitan area, state capital and 34 neighboring towns. Our results show the possibly spreading serovars in Minas Gerais State and contribute to knowledge of human leptospirosis, aiming at improving the prevention, control of the disease, as well as the treatment of infected patients.

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

    Full Text Available 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.

    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)

    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 2 (quartz) associated with a finer particle size distribution.

    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.

    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 The study aimed to fit mathematical models for the construction of Site Index curves and to estimate heights at different ages for Eucalyptus grandis in the Campos Gerais region, Parana State. The data used to fit the models came from permanent, temporary plots and pre-harvesting inventory, covering ages from 2.5 to 26.5 years. Several models were tested to represent the sites and the hypsometric relationship. The Site Index curves were constructed by the guide-curve method. For the Site Index, the Chapman-Richards model showed the best fit and precision statistics, generating 5 Site Index curves (range of 5 m with the Chapman-Richards model. The four hypsometric models tested showed satisfactory performance and similar statistics and the inclusion of the variables dominant height or site index did not substantially improve the goodness of fit statistics, but the residues were more homogeneous and closer to zero.

    With the reformulation of the CNEN-NN-3.05 standard in December 2013, Brazil's Nuclear Medicine (NMS) services have to perform a greater number of quality controls for SPECT and PET equipment. However, little is known about the reality of the quality control programs of these services regarding the application of the new standard. Thus, in this context, the objective of the present study was to evaluate the quality control program of MNSs in the state of Minas Gerais. All NMSs in the state of Minas Gerais were invited to participate in the project. Of these, 34.48% (20 facilities) agreed to participate in the project, 50.00% (29 facilities) did not respond to the invitation and 15.52%(9 facilities) declined their participation. Thus, as of November 2015, 20 SPECT and 2 PET/CT equipment were evaluated for the performance of the quality control tests recommended by the new CNEN standard. The phantoms required for the evaluation came from the Laboratory of Dosimetry and Quality Control of UFMG. Even with the deadlines set by CNEN for the implementation of the quality control program in the NMSs, more than 50% of the evaluated services did not implement the quality controls, and the absence of specific phantoms is the main reason for the failure. Among the problems found in the installations, the most critical were: collimators with no conditions of use in the clinical routine, linearity problems of the evaluated image and values of image uniformity superior to the limits of acceptance. Problems in the uniformity and linearity of the image found directly impacted the performance of other tests, such as spatial resolution, SPECT performance, among others. In a general way, the NMSs in the state of Minas Gerais evaluated with the present study are in clinical feasible conditions. (author)

    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 Os sistemas de informações geográficas podem ser considerados instrumentos para mapear e indicar respostas às várias questões sobre o planejamento urbano e regional, o meio rural e levantamento dos recursos renováveis. A execução do zoneamento climático para a cultura do café, utilizando-se sistemas de informações geográficas, proporciona resultados mais satisfatórios, visto que os dados inicialmente coletados são armazenados, facilitando sua manipulação e análise e exibindo um resultado final de melhor qualidade, quando comparado com outros métodos mais tradicionais. As características agroclimáticas das diversas regiões influenciam, diferentemente, a produtividade final da cultura do café. Assim, este trabalho teve como objetivo analisar o grau de correspondência entre o zoneamento climático para a cultura do café e o potencial produtivo da cultura no Estado de Minas Gerais. O zoneamento climático mostrou-se eficiente na delimitação das regiões climaticamente homogêneas quanto à capacidade produtiva da cultura do café no Estado; Minas Gerais apresenta 37% de seu território com condições adequadas ao cultivo do café, 45% com alguma restrição e 18% são considerados inaptos; as áreas aptas ao cultivo do café se concentram no Centro-Sul do Estado.The geographical information system (GIS is a data management computational program, which is used to capture, store, recover, analyze and exhibit the geographically referenced space data. So, it is an important tool in elaboration of the climatic zonings, besides making the work faster and exhibiting a better-quality final result as compared to other traditional methods. The climatic characteristics of the areas may influence the final productivity of the coffee crop in different ways. Thus, the objective of this study was to analyze the degree of correspondence between climatic zoning and the productive potential for coffee crop in Minas Gerais State, Brazil

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

Utilizaram-se dados de temperatura média e precipitação de 110 estações meteorológicas de Minas Gerais e de Estados circunvizinhos; com base nesses dados calculou-se o índice de umidade de Thornthwaite & Mather para uma capacidade de armazenamento de água no solo de 125 mm. Elaboraram-se mapas de aptidão térmica e hídrica, a partir da temperatura média e do índice de umidade, para essa cultura, com a sobreposição dos mapas, obteve-se o mapa de aptidão agroclimática do Estado para a cultura da acerola. Cerca de 12,6% do território de Minas Gerais, região sul, e uma pequena parte da região central, são inaptos para o cultivo da aceroleira, devido à ocorrência de baixas temperaturas. Em 55,8% do Estado observam-se condições favoráveis para o cultivo da aceroleira enquanto em 4,5% as condições são regulares. Áreas com aptidão restrita compreendem 27% do Estado, sendo que em 18% o cultivo é recomendado somente com o emprego de irrigação, devido à restrição hídrica, enquanto nos outros 9% o cultivo é limitado pelo excedente hídrico.This study aimed to accomplish the agroclimatic zoning of Minas Gerais State, in order to provide subsidies for selection of areas for implantation of the West Indian Cherry (Malpighia glabra L. crop. The average temperature and precipitation data relative to 110 meteorological stations located in Minas Gerais and surrounding states were used. Based on these data, the moisture index by Thornthwaite & Mather for a soil water storage capacity of 125 mm was calculated. The thermal and hydric aptitude maps were drawn for the crop from the average temperature and moisture index. The State agroclimatic aptitude map was obtained by superposing these maps.

    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

    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.

    Although the occurrence of Pleistocene mammals is abundant in many localities of Minas Gerais State (e.g., Lagoa Santa, Janaúba, Bambuí, Cordisburgo, Patos de Minas, Araxá), there are no references at present of Quaternary megafauna in Uberaba, Triângulo Mineiro, southeastern Brazil. This region is traditionally recognized for its taxonomically diverse fauna of the Late Cretaceous Bauru Group. In 2006, fossil material attributed to giant ground sloth Eremotherium laurillardi (Xenarthra, Megatheriidae), a typical taxon of the Brazilian Pleistocene, was discovered in the Uberaba City (Minas Gerais State). The specimen (CPP 1122) which is here described consists of several cranial and postcranial bones of a single individual. The material was confined to a small alluvial deposit, yielding in the Córrego da Saudade stream, which due its restricted area distribution it is not represented in geological maps.

    The State Program of Quality Control in Mammography (PECQMamo) of the state of Minas Gerais was established in 2004 and consists of tests for evaluation of image quality and performance of equipment used in the diagnosis of breast cancer, and evaluation the infrastructure of mammography centers. The monthly monitoring of image quality in mammography is part of this program that has been executed since May 2009 with a character essentially educational. In the assessment of individual services that participate in the monthly monitoring, there was an increased percentage of average annual compliance from 2009 to 2010 in all 85 services with the exception of one service. Therefore, evolution of the performance of the services evaluated, since the program began, shows a positive impact on the numbers, confirming the relevance of this type of operation of Sanitary Surveillance in the area of quality in mammography.

    The increasing practice of ecotourism and rural tourism in the State of Minas Gerais, Brazil, highlights the importance of studies concerning the occurrence of potential intermediate hosts of Schistosoma mansoni. This study aimed to identify species of Biomphalaria snails in municipalities along the Estrada Real, an important Brazilian tourism project. The specimens were collected in different water collections of 36 municipalities along the Estrada Real in the southeast of the State of Minas Gerais. Biomphalaria species were characterized using both morphological and molecular approaches. The research was conducted between August 2005 and September 2009 and all the sites visited were georeferenced using GPS. Six Biomphalaria species were found in 30 of the 36 municipalities studied: glabrata, tenagophila, straminea, peregrina, occidentalis and schrammi. The first three species of Biomphalaria, recognized as intermediate hosts of S. mansoni, were present in 33.3%, 47.2% and 8.3% of the municipalities studied, respectively. The mollusks were found in different types of water collections and no infection by S. mansoni was detected. The highest occurrence of Biomphalaria concentration was verified in the area covered by the Caminho Novo route (Diamantina/MG to Rio de Janeiro/RJ). Considering the occurrence of schistosomiasis in the State of Minas Gerais and the socioeconomic repercussions involved in the Estrada Real Project, this work focuses on the vulnerability of water collections due to the presence of Biomphalaria mollusks and emphasizes the need for epidemiological surveillance and sanitary and educational measures integrated with the local community and tourism sectors.

    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)

    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 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 This study's objective was to search for Cryptosporidium sp. in diarrheic feces from children aged zero to 12 years and cared for at medical units within Universidade Federal de Uberlândia or at a private practice in Uberlândia, State of Minas Gerais, Brazil, from September 1992 to August 1993. Three fecal samples preserved in 10% formalin, were collected from 94 children. Oocyst concentration was performed through Ritchie's (modified method and staining of fecal smears for each sample (total of 1128 slides was done by the "Safranin/Methylene Blue" and the "Kinyoun (modified" techniques. The Hoffmann, Pons & Janer method was also employed to look for other enteroparasites. From 94 children, 4.26% excreted fecal Cryptosporidium oocysts. The infection seemed to vary according to age: 5.08% of patients aged zero to two years old; 33.33% of those aging eight to ten years (P>0.05. Cryptosporidium appeared in November, December and March, during the rainy season. 20.21% of the children harbored at least one enteroparasite different from Cryptosporidium, mainly Giardia intestinalis (12.77%. From Cryptosporidium infected patients, two had only this kind, another harbored Giardia intestinalis; the last one hosted Strongyloides stercoralis.

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

    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.

    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)

However the majority of techniques proposed in the organic agriculture have beeing use empiricaly to the coffee plantings, especialy in Minas Gerais state, the producer state coffee in Brazil. Considering the low natural soil fertility of this coffee region and the great nutrient exportation from the coffee crops, the objective of this research is to evaluate possible negative fators for the organic coffee production related with soil fertility and the nutritional status of plants. Soil and leaf samples were collected in 21coffee plantings of Minas Gerais. The soil samples were analyzed for pH, P, K, P, K, Ca, Mg, S, Al and organic matter contents. Foliar samples were analyzed for N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn contents. Considering the patterns established for conventional coffee plantings found in literature, frequencies were calculated when soil and leaf contents were low, high and adequate. The data were analyzed through descriptive statistics. More data is required on tissue analysis and soil fertility in order to effectively reveal nutritional disorders in organic coffee plantings.

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

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.

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

    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 [es

    Açucena Municipality, Rio Doce Valley, State of Minas Gerais, Brazil temporarily (2001-2005) interrupted epidemiological surveillance for Chagas disease. 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. 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. 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. 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 INTRODUCTION: The increasing practice of ecotourism and rural tourism in the State of Minas Gerais, Brazil, highlights the importance of studies concerning the occurrence of potential intermediate hosts of Schistosoma mansoni. This study aimed to identify species of Biomphalaria snails in municipalities along the Estrada Real, an important Brazilian tourism project. METHODS: The specimens were collected in different water collections of 36 municipalities along the Estrada Real in the southeast of the State of Minas Gerais. Biomphalaria species were characterized using both morphological and molecular approaches. The research was conducted between August 2005 and September 2009 and all the sites visited were georeferenced using GPS. RESULTS: Six Biomphalaria species were found in 30 of the 36 municipalities studied: glabrata, tenagophila, straminea, peregrina, occidentalis and schrammi. The first three species of Biomphalaria, recognized as intermediate hosts of S. mansoni, were present in 33.3%, 47.2% and 8.3% of the municipalities studied, respectively. The mollusks were found in different types of water collections and no infection by S. mansoni was detected. The highest occurrence of Biomphalaria concentration was verified in the area covered by the Caminho Novo route (Diamantina/MG to Rio de Janeiro/RJ. CONCLUSIONS: Considering the occurrence of schistosomiasis in the State of Minas Gerais and the socioeconomic repercussions involved in the Estrada Real Project, this work focuses on the vulnerability of water collections due to the presence of Biomphalaria mollusks and emphasizes the need for epidemiological surveillance and sanitary and educational measures integrated with the local community and tourism sectors.

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

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.

    Restructuring of the Brazilian financial sector was consolidated through the combination of mass lay-offs, automation, and outsourcing, in addition to business re-engineering with leveling of hierarchical echelons, labor casualization, and multi-function jobs. In order to comply and deal with the new demands, bank employees had to increase their schooling, become multi-functional and expert sales attendants, and submit to substandard conditions in the workplace, increased workload, overtime, and low wages. The purpose of the current study was to examine the restructuring process in a state-owned bank in Minas Gerais State, Brazil, and its impacts on workers' health. The study also analyzes absenteeism rates from 1998 to 2003, when there was an increase in diseases such as repetitive stress injury (RSI)/work-related musculoskeletal disorders (WRMD) and mental/behavioral disorders, accounting for 56% and 19% of sick leaves. The process has continued to the present, with a restrictive recruitment policy. Further study is needed to confirm the results.

Somente as injúrias mecânicas e as raízes expostas estavam com baixas porcentagens fora do ideal. Os problemas que mais contribuem para a baixa qualidade das mudas, tanto em viveiros públicos quanto particulares, são a altura abaixo da recomendada e a ausência de podas de condução e de formação. Portanto, os primeiros esforços para a melhoria da qualidade devem ser sobre essas características. A análise indicou ainda que grande parte dos problemas se deve à falta de treinamento dos funcionários e domínio das técnicas silviculturais necessárias à produção das mudas, principalmente em se tratando de viveiros particulares, onde as mudas estão com qualidade inferior às dos viveiros públicos.This study was carried out in nurseries in the State of Minas Gerais to evaluate the quality of tree seedlings destined to urban areas. Twelve nurseries were evaluated; half of them run by public institutions and the other half were private nurseries. The results showed that, in general, there is not a concern with quality of seedling, which is proven by the high percentages of low quality seedlings. Only plants with mechanical injuries and exposed roots had low off standard percentages. In both public and private nurseries, the problems that most contributed for low quality seedlings are height bellow recommended and lack of pruning for tree conduction and formation. Therefore, efforts for quality improvement must first be put on these characteristics. Furthermore, the analyses showed that the

    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.

    To describe associations between pregnancy rates in adolescence and socioeconomic and social responsibility indicators in the municipalities of the State of Minas Gerais, Southeast of Brazil, in the year of 2010. Ecological study using data from the Brazilian Live Birth Information System (SINASC). The percentage of live births to adolescent mothers (LBAM) for each municipality was calculated based on the quotient between number of born alive infants of mothers aged 10-19 years old and total number of live births in the year of 2010. Fully Bayesian models were used to obtain the percentages of LBAM adjusted for spatial effects and to assess possible associations with socioeconomic and social responsibility indicators. The crude percentage of LBAM for the total number of live births in the municipalities of Minas Gerais in 2010 ranged from 0 to 46.4%, with median percentage being 19.6% and the first and third quartiles being 15.6 and 23.1%, respectively. This study has demonstrated a close relationship between adolescent pregnancy and socioeconomic indicators. LBAM percentages were found to be higher in municipalities with low population density, low human development index and other low development indicators. The strong relationship between LBAM percentages and socioeconomic indicators suggests that adolescent pregnancy is more a social than a biological problem. Therefore, programs and actions should go beyond sexual education and information on preventive health methods.

    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

    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)

    Full Text Available Schistosomiasis mansoni is not just a physical disease, but is related to social and behavioural factors as well. Snails of the Biomphalaria genus are an intermediate host for Schistosoma mansoni and infect humans through water. The objective of this study is to classify the risk of schistosomiasis in the state of Minas Gerais (MG. We focus on socioeconomic and demographic features, basic sanitation features, the presence of accumulated water bodies, dense vegetation in the summer and winter seasons and related terrain characteristics. We draw on the decision tree approach to infection risk modelling and mapping. The model robustness was properly verified. The main variables that were selected by the procedure included the terrain's water accumulation capacity, temperature extremes and the Human Development Index. In addition, the model was used to generate two maps, one that included risk classification for the entire of MG and another that included classification errors. The resulting map was 62.9% accurate.

    Full Text Available Henochilus wheatlandii, the only species of this genus, is critically endangered and was considered extinct for over a century. The rediscovery of this fish in 1996 made it possible to study its phylogenetic relationships with other species in the subfamily Bryconinae. The aim of this study was to characterise the karyotype of H. wheatlandii. Standard staining, C-positive heterochromatin and nucleolar organiser region (NOR banding, chromomycin A(3 staining, and fluorescent in situ hybridisation (FISH using 5S rDNA and 18S rDNA probes were conducted on nineteen specimens collected in the Santo Antonio River, a sub-basin of the Doce River in Ferros municipality, Minas Gerais State, Brazil. Henochilus wheatlandii shared the same diploid number and chromosome morphology as other species of Bryconinae. However, its heterochromatin distribution patterns, NOR localisation, and FISH patterns revealed a cytogenetic profile unique among Neotropical Bryconinae, emphasizing the evolutionary uniqueness of this threatened species.

One of these groups, that was identical to a previously described karyotype (n = 15; 2n = 30, had a stable chromosome number and was rich in acrocentric chromosomes, whereas the other had a variable chromosome number (n = 12 to 14; 2n = 25 to 28 and was rich in pseudo-acrocentric chromosomes. We propose a hypothesis explaining the dynamics of the modifications which occurred in the karyotype of this species, based on the minimum interaction theory of Imai et al. (1986, 1988, 1994 and on the chromosome rearrangements and heteromorphisms observed by us.

    Full Text Available The objective of this study was to analyze the relationship between depressive symptoms and eating disorders in female adolescents. The sample included 371 girls ranging from 12 to 16 years of age in Juiz de Fora, Minas Gerais State, Brazil. The study used the Eating Attitudes Test (EAT-26 and Major Depression Inventory (MDI to evaluate eating disorders and depressive symptoms, respectively. The linear regression model showed that 18% of the EAT-26 scores were influenced by MDI (F(1, 370 = 14.18; p = 0.001. Moreover, the findings indicated a statistically significant association between depressive symptoms and eating disorders (χ2 = 14.71; Wald = 12.90; p = 0.001. The authors concluded that depressive symptoms were related to eating disorders in female adolescents. Thus, girls with some level of depression showed a greater tendency to adopt disordered eating as a daily habit.

    Intense mining activities in Minas Gerais State, Brazil. Iron Quadrangle, the central region of Minas Gerais State- Brazil, has important mineral reserves of Fe (the World's second largest iron ore producer), Mn, Cu, Sb, As, Au, Al, and U. The intense mining activities in Minas Gerais State throw out tons of waste in the open air, water, sediment and soil. The considerable accumulated concentrations of heavy metals and toxic elements penetrate the soil, underground waters, rivers, and lakes jeopardizing the environment quality. A great amount of heavy metals enter Pampulha Reservoir via it's main tributaries (Sarandi and Ressaca). Although no water quality classification has been carried out for these tributaries, the reservoir is expected to be in class 2 of the CONAMA-86 system. The Pampulha Lake is a depth of 8 m and an area of 43 km 2 , in a hot, humid climate with a summer rainy season, >18 degree C in the coldest months. A great number of persons use the water for fishing and swimming in the contaminated water. The figure l localizes the Pampulha Lake in Brazil. Instrumental Neutron Activation Analysis, INAA, and Inductively Coupled Plasma-Mass Spectrometry-High Resolution, ICP-MSHR, were applied to determine Al, As, B, Ba, Co, Cr, Cs, Cu, Fe, K, Mg, Mn, Mo, Na, P, Pb, Rb, Zn and Ti. Instrumental Neutron Activation Analysis - INAA is based in a simultaneous irradiation compareson between standard and studied samples in a nuclear reactor. The irradiation characteristics are chosen to determine the isotopes in the best conditions. In this work the INAA, was applied using the TRIGA MARK I IPR - Rl reactor at the Nuclear Technology Development Center from the National Committee of Nuclear Energy (CDTN/CNEN), in Belo Horizonte city, Minas Gerais State, Brazil. At 100 kW of potency the flux of neutrons is 6.6 1011 ri.cm -2 .s -l .

The current study presents data on the prevalence and characteristics of individuals that drive under the influence of alcohol (DUI in nine regions of the city of Belo Horizonte, Minas Gerais State, Brazil. A total of 1,656 drivers were interviewed, of whom 1,254 (76% agreed to answer a structured questionnaire and submit to the breathalyzer test. The breathalyzer test was positive in 15% of these drivers. The logistic regression model predicted 1.5 times higher odds of a positive breathalyzer test in drivers over 31 years of age and 4.5 times higher in individuals that reported at least weekly alcohol consumption. In addition, drivers in the Barreiro region showed two-fold odds of a positive breathalyzer test. Focused studies with sobriety checkpoints can monitor DUI behavior, drivers' characteristics, and traffic risks, meanwhile orienting public policies to prevent drinking and driving.

    Archaeological ceramics of Tupiguarani Tradition are found in many parts throughout the Brazilian territory and have many similarities. Fragments of Tupiguarani pottery found in the archaeological site known as Beltrao, in the municipality of Corinto, state of Minas Gerais, were identified and collected by researchers of the LAEP/UFVJM, in Diamantina, also in Minas Gerais. A selected fragment of about 15 mm-thick, with a color gradation across the ceramic wall ranging from red, on one side, grayish in the middle and orange on the opposite side, was transversely cut and a series of subsamples of powdered materials were collected from different depths across the wall, in layer segments of ∼3 mm, from the orange side. These powdered subsamples were analyzed with X-ray fluorescence and diffraction spectroscopy and 57 Fe Moessbauer spectroscopy at room temperature (298 K) and at 80 K. According to the XRF results, the elementary composition does not clearly vary with the depth in the sample. The powder XRD analysis revealed the occurrence mainly of quartz and muscovite. Results of 57 Fe Moessbauer spectroscopy reveal that hematite is the magnetically ordered phase. An Fe 2+ component appears for the grayish subsample. According to these results, the red subsample seems to be the external part of the pottery, representing the side that had direct contact with fire used to burn the precursor clay in air for this primitive ceramics preparation. The grayish middle layer is probably due to burning clay mixed with some ashes containing residual carbon, under milder temperature than on the external . (author)

    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.

    The present report refers to the Lima Duarte sheet (SF.23-X-C-VI) systematic geological mapping, on the 1:100.000 scale. The surveyed area, localized in the Zona da Mata, Juiz de Fora micro-region, in South Minas Gerais, is dominantly composed by metamorphic rocks of the granulite and amphibolite facies and presents important diphtheritic process. An analysis of the Crustal Evolution Patterns based mostly on geological mapping, and gravimetric, air magneto metric and geochronologic data is given in the Chapter 6, Part II, of the text. Geophysical information is in the Chapter 5, Part II. Seventy two samples were analysed for oxides, trace-elements and REE, to provide litho environment and metallogenesis definition subsidies. Were studied 174 petrographic thin section, and 48 samples of quartzite and schist residual materials were analysed for heavy metals. Seven hundred and fifty outcrops were described. A geochemical survey, based on 81 pan concentrated samples and 277 stream sediments was carried out throughout the Sheet. The anomalies found in the stream sediments reflect the geochemical signature of the analysed elements for the litho types of the investigated terrains. (author)

    : To evaluate the cost-benefit of implementing a Telecardiology service in remote, small towns in the state of Minas Gerais, Brazil. METHODS: The study used the database from the Minas Telecardio (MTC Project, developed from June 2006 to November 2008, in 82 towns in the countryside of the state. Each municipality received a microcomputer with a digital electrocardiograph, with the possibility of transmitting ECG tracings and communicating with the on-duty cardiologist at the University hospital. The cost-benefit analysis was carried out by comparing the cost of performing an ECG in the project versus the cost of performing it by patient referral to another city. RESULTS: The average cost of an ECG in the MTC project was R$ 28.92, decomposed into R$ 8.08 for the cost of implementation and R$ 20.84 for maintenance. The cost simulation of the ECG with referral ranged from R$ 30.91 to R$ 54.58, with the cost-benefit ratio being always favorable to the MTC program, regardless of the type of calculation used for referral distance. The simulations considered the financial sponsor's and society's points-of-view. The sensitivity analysis with variation of calibration parameters confirmed these results. CONCLUSION: The implementation of a Telecardiology system as support to primary care in small Brazilian towns is feasible and economically beneficial, and can be used as a regular program within the Brazilian public health system.

    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 238 U, 226 Ra, 222 Rn, 210 Po and 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 222 Rn, 226 Ra and 228 Ra have been found in concentrations that may be of health concern. 226 Ra and 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. 226 Ra activity concentrations varied from 83 to 3,599 mBq L-1, the highest value determined at Venancio spring. Activity concentrations of 228 Ra ranged from 69 to 4,481 mBq L-1. 228 Ra/ 226 Ra activity ratios varied from 0.079 to 4.2. (author)

As autoridades sanitárias devem priorizar o controle da compra de animais para reprodução, que não apresentem garantias sanitárias e incorporar essa medida às ações de educativas.A study to characterize the epidemiological status of brucellosis was carried out in the State of Minas Gerais. The State was divided in seven regions. Three hundred herds were randomly sampled in each region and a pre-established number of animals was sampled in each of these herds. A total of 20,643 serum samples from 2,204 herds were collected. In each herd, it was applied an epidemiological questionnaire focused on herd traits as well as husbandry and sanitary practices that could be associated with the risk of infection. The serum samples were screened for antibodies against Brucella spp. by the Rose-Bengal Test (RBT, and all positive sera were re-tested by the 2-mercaptoethanol test (2-ME. The herd was considered positive if at least one animal was positive on both RBT and 2-ME tests. The prevalence of infected herds and animals in the State were, respectively, 6.0% [5.0-7.1%] and 1.1% [0.78-1.4%]. In the productive regions, the prevalence of infected herds and animals were, respectively: regions 1, 4.7% [2.7-7.7%] and 0.82% [0.06-1.6%]; region 2, 7.2% [4.6-10.6%] and 1.2% [0.53-1.8%]; region 3, 6.8% [4.3-10.0%] and 1.5% [0.47-2.4%]; region 4, 6.5% [4.1-9.8%] and 1.1% [0.39-1.7%]; region 5, 3.8% [2.0-6.5%] and 0.40% [0.11-0.69%]; region 6, 6.2% [3.8-9.6%] and 0.66% [0.29-1.0%]; and region 7, 11.0% [7.7-15.0%] and 1.7% [0.92-2.6%].

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

    Full Text Available No Brasil, ainda são relativamente poucos os estudos envolvendo erodibilidade do solo, principalmente Cambissolos, dada a morosidade na obtenção dos resultados de experimentos com chuva natural. O conhecimento dos índices de erosividade e de erodibilidade é importante para o planejamento conservacionista, contribuindo para a sustentabilidade dos solos. Este estudo teve como objetivos determinar a erosividade da chuva e a erodibilidade de Cambissolo Háplico Tb distrófico típico e Latossolo Vermelho distroférrico típico, sob chuva natural, em Lavras (MG, no período de 1998 a 2002. Os dados de precipitação pluviométrica foram obtidos na Estação Climatológica Principal de Lavras, localizada no campus da Universidade Federal de Lavras, próxima das unidades experimentais de perdas de solo. A erosividade (EI30 foi determinada a partir do produto da energia cinética da chuva pela sua intensidade máxima em 30 min. Estes dados, correlacionados com as perdas de solo, permitiram obter o índice de erodibilidade dos solos. A precipitação total média anual foi 1.287 mm e a erosividade média foi de 4.865 MJ mm ha-1 h-1 ano-1. A erodibilidade foi 0,0355 Mg h MJ-1 mm-1 para o Cambissolo e 0,0032 Mg h MJ-1 mm-1 para o Latossolo, em consonância com seus atributos mineralógicos, químicos, físicos e morfológicos diferenciais.Relatively few studies in Brazil have investigated soil erodibility, mainly for Cambisols (Inceptisols, due to the tediousness of data collection in natural rainfall experiments.

Essas amostras apresentavam, respectivamente, 5,0, 1,2 e 1,4 mg dm-3 de S disponível, obtidos pelo extrator Ca(H2PO42, 500 mg L-1 de P em HOAc 2 mol L-1. O experimento correspondeu a um fatorial 3 x 5, sendo três solos e cinco doses de S (0, 20, 40, 80 e 160 mg dm-3, dispostos em blocos casualizados, com quatro repetições. A umidade, controlada pelo uso de um tensiômetro por vaso, foi mantida próximo a -10 kPa durante todo o ensaio. O fluxo em massa foi o principal mecanismo de transporte de S para a superfície das raízes da soja. Quando a concentração de S na solução do solo foi alta, esse mecanismo supriu quantidades de S superiores às absorvidas pela planta. A contribuição da difusão para o suprimento de S ocorreu apenas em baixa concentração desse nutriente na solução do solo.A greenhouse experiment was carried out to evaluate the mass flow and diffusion contributions on sulphur transport toward soybean roots in soil surface samples (0-20 cm of three soils collected in Viçosa, Paracatu and Lassance, Minas Gerais State, Brazil.

Capture of dragonfly adults during two short expeditions to Parque Nacional da Serra do Cipó, Minas Gerais State, using three distinct collecting methodsaerial nets, Malaise and light sheet trapsis reported. The results are outstanding due the high number of species of Gomphidae (7 out of 26 Odonata species, including a new species of Cyanogomphus Selys, 1873, obtained by two non-traditional collecting methods. Because active collecting with aerial nets is the standard approach for dragonfly inventories, we discuss some aspects of the use of traps, comparing our results with those in the literature, suggesting they should be used as complementary methods in faunistic studies. Furthermore, Zonophora campanulata annulata Belle, 1983 is recorded for the first time from Minas Gerais State and taxonomic notes about Phyllogomphoides regularis (Selys, 1873 and Progomphus complicatus Selys, 1854 are also given.

    Full Text Available The scientific community has discussed a reformulation in education in order to meet new goals in the learning processes. It is a challenge for universities to modify their social role by adding new teaching methods in their undergraduate programs to fit into this current context. The motivation of this study is to verify if the adoption of active teaching methods in the Accounting course at a private Higher Education Institution located in the region of the Zona da Mata, State of Minas Gerais, contributed to the performance of its students. In this research, performance is characterized at the improvement in students' grades. The active methods, in response to this educational reformulation, are concerned with preparing a critical student, capable of acting in the contemporary market, subject to constant changes. The study period covers the years between 2011 and 2014. We sought to answer the following question: Is there an impact on the performance of accounting students after the implementation of active methods at the HEI investigated? To test the proposed hypothesis, we used Student's T test and regression methods. The analyzed data were collected from documents provided by the institution's employees. The results show that there is evidence that the use of active methods in the accounting course contributed to the students' performance in the period studied.

    Full Text Available Abstract: This study covers the region between the cities of Sacramento and Araguari/Uberlândia (Minas Gerais State, Brazil, where basalt flows from the Paraná Continental Magmatic Province outcrop. The investigated rocks present tholeiitic signature, with high titanium content, and are classified as Pitanga magma-type. The preserved basalt thickness is between 10 and 200 meters and individual flows do not exceed 15 meters thick. Flows were identified as sheet lobes, smaller and thinner flows units - stacked laterally and vertically forming compound lavas -, or frontal, centimetric lobes. The basalt flows show decimetric to metric intercalations of clastic sedimentary rock, with depositional characteristics that can vary from aeolian to lacustrine, and are important markers on prevailing environmental conditions. The plagioclases are dominantly labradorite and pyroxene is augite, whereas olivine can be hyalosiderite or hortonolite/ferrohortonolite. The behavior of the major, minor and trace elements is compatible with the presence of at least two parental magmas, which were subjected to fractional crystallization mainly of plagioclase, clinopyroxene, ilmenite and magnetite. There is a chemistry distinction between basalts from Sacramento to those from Araguari/Uberlândia region, the former one showing more evolved than the last one. The high (La/LuN values are indicative of partial melting of a garnet peridotite, while the Rare Earth Elements (REE values are indicative of fractional crystallization.

    Full Text Available Advances have occurred in relation to the coverage of water supply and sanitation in Brazil, however inequalities are still observed in relation to the coverage of these services, reflecting the importance of diarrheal disease in the Brazilian epidemiological context. The aim of this study was to measure the impact of the water supply and sanitation system on diarrheal diseases among children aged under five. The global burden of diarrhea was calculated based on the attributable population fraction, using information on prevalence and relative risks from the 2000/2010 censuses and a study by Pruss et al. The north of the State of Minas Gerais, the Northeast and Jequitinhonha regions had the highest disability-adjusted life year (DALY rates and ratios. The fraction of diarrhea attributable to the water supply and sanitation system was 83%, decreasing to 78.3% where sanitation had 100% coverage. An inverse relationship was found between DALY rates and attributable fractions and per capita GDP. Broadening the scope and coverage of services and improving the quality of water available in homes is an urgent requirement. These measures will bring economic and social benefits related to the reduction of diarrheal diseases and consequent improvement of the quality of life of children aged under five.

    Full Text Available Oogenesis involves a set of transformations which are undergone by female germ cells These cells change into oogonias and then into mature oocytes. Sexually mature female fish were collected monthly, during one year, from the Sapucaí River, a tributary of the Rio Grande, which is part of the Furnas Reservoir in the state of Minas Gerais. During the several stages of maturation, we observed small round oogonias with a large nucleus, a single nucleolus, and weakly stained cytoplasm with eosinophilic granules. The primary oocytes showed a large basophilic nucleus, with a developed peripheral nucleolus and a reduced cytoplasm. The previtellogenic oocytes presented voluminous cytoplasm and nucleus with several small peripheral nucleoli. The oocytes underwent vitellogenesis with the development of the zona radiata and the follicle cells. Their cytochemical reactions indicated that the two layers of the zona radiata of A. fasciatus contained proteins and polysaccharides. The initially squamous follicle cells, became cuboidal. In mature oocytes, the nucleus moved toward the periphery, next to the micropyle, and the yolk granules formed by proteins, fulfilled the cytoplasm. The clear unstained vesicles are likely to be the cortical alveoli in the perivitelline region.

    The Formoso river is an important tributary of The Sao Francisco River in the Northwest of Minas Gerais State. There are more than 100 families who live and depend exclusively on the natural and environmental resources of its basin. It is inserted in the Cerrado Biome where its waters drain large agropecuary landed estates, what directly influences the physicochemical characteristics of superficial waters and streams sediments. The Cu, Cd, Cr, Ni, Pb and Zn parameters were analyzed in 22 sediment samples using the chemical partial acid extraction technique and ICP-OES reading and the results were compared to the CONAMA resolution 344/04. It was found that the levels of Cd and Cr are above the levels recommended by this resolution. Mineral characterization was done by X-Ray diffractometry and geochemical litho types analysis was done by ICP-AAS. The presence of these elements in the longitudinal profile whose main sources are the litho types. There is a link between the lithopedologic variable, the typology of the fluvial channel, the hydrodynamic of the basin and the distribution and transport of metals throughout the longitudinal profile of the river of Cd and Cr. The morphologic characteristics of the fluvial canal and the hydrodynamics of the basin have played an important role as a mechanism for the distribution and transport of metals in the sediments

    Full Text Available The Volta Grande Environmental Unity represents one of the few remnants of Cerrado protected by areserve in the Triângulo Mineiro region, municipalities of Conceição das Alagoas (19°55' S, 48°23' W andMiguelópolis (20°12' S, 48°03' W, in the states of Minas Gerais and São Paulo, respectively. The mammalian fauna ofthis reserve was inventoried between 2003 and 2004 to generate estimates about taxonomic composition, richness, andabundance of species. A sampling effort of 832 trapping-nights resulted in 24 species recorded. Cumulative curvessuggest that the overall inventory is not complete and that more species are likely to be registered. The majority ofspecies recorded is widespread along the Cerrado, but include some noteworthy records of endangered species, such asthe Giant anteater (Myrmecophaga tridactyla and the Manned wolf (Chrysocyon brachyurus. The record of thearboreal cricetid rodent Oecomys bicolor represents a slight extension of the southeastern limit of its distribution.

    Full Text Available The fruits of the palm Butia capitata are harvested from wild populations. A lack of knowledge of their ecology has hindered the establishment of sustainable management practices. We investigated fruit biometric parameters, yield and phenology in two populations of B. capitata in the cerrado (savanna in the north of the state of Minas Gerais, Brazil, at two study sites: in the communities of Mirabela (Fazenda Baixa site, studied from December 2006 through December 2007 and Campos (studied throughout 2007. Overall, adult palms produced an annual average of 7.6 leaves. At the Fazenda Baixa site, the mean annual number of infructescences was 4.9, compared with only 1.6 at the Campos site, and the annual yield was 197-373 and 145-468 fruits per tree (in 2006 and 2007, respectively, compared with 67-247 at the Campos site. Reproductive events were seasonal and influenced by rainfall distribution. Typically, inflorescences and immature infructescences appeared in the dry season, mature infructescences appearing in the rainy season. Inflorescence production and fruit biometric parameters differed between the two populations. Fruit yield correlated with height and leaf biomass. We found that B. capitata fruits, which are highly perishable, should be harvested when nearly-ripe and remain attached to the infructescence during transport. Our findings have important implications for the development of strategies for sustainable management and in situ conservation of populations of this species.

    Full Text Available Abstract Obesity prevalence is rapidly increasing in developing countries. Existing research investigating social patterning of obesity and its risk factors in Latin American urban contexts has inconsistent findings. This study analyzed a multistage household survey in adults in Belo Horizonte, Minas Gerais State, Brazil. Marginal models were used to examine the association of education and household and neighborhood income with body mass index (BMI, obesity, physical inactivity, and low fruit and vegetable intake after adjusting for age and ethnicity and stratifying by sex. BMI and obesity were inversely associated with education in women. BMI was positively associated with household and neighborhood income in men. Additionally, physical inactivity and low fruit and vegetable intake were inversely associated with education and household income in both men and women, and physical inactivity was inversely associated with neighborhood income in men. Understanding the drivers of these patterns will allow for development of appropriate policy and interventions to reduce cardiovascular disease risk in large cities in Latin America.

    The scope of this article is to evaluate the SISVAN as a tool for planning, management and evaluation of food and nutrition actions in primary healthcare in the Unified Health System (SUS). It involved a cross-sectional study composed of a stratified random sample of the municipalities in the State of Minas Gerais. The subjects of the research were municipal officials of SISVAN who filled out a structured questionnaire. Descriptive analysis of the data was performed with the construction of simple and bivariate tables. It was observed that those responsible for SISVAN, collect (50%) and input (55%) weight, height, and food consumption data; whereas 53%, 59% and 71% do not analyze and do not recommend or perform nutrition actions, respectively. This being the case, most of those responsible do not use the information for planning, management and evaluation of food and nutrition traits. The findings show that the SISVAN is not used to its full potential; the data generated have not been used for planning, management and evaluation of nutrition services in primary healthcare in the SUS.

    Chemical (Sr: Ba: Rb) and zircon typology data from the Nazare Paulista, Mairipora/Cantareira, Cunhaporanga, Tres Corregos, Morungaba, Socorro, Itu, Graciosa and Serra Carambei granitoid complexes from the states of Minas Gerais, Sao Paulo and Parana (SE/S Brazil) are presented and discussed. By the zircon typology method these complexes are reffered, respectively, to the 2nd crustal, 3rd crustal/low temperature C-A, low temperature C-A, medium temperature C-A, medium/high temperature C-A, K-SA/Alkaline and alkaline serie which are considered as generated under increasing temperature associated with a progressive major participation of mantellic material. All these series, with the exception of the medium to high temperature calc-alkaline complexes Socorro and Morungaba whose chemical data come from several laboratories, display different positions and behaviour in the Sr: Ba: Rb diagram which reinforce the use of the zircon typology method in the study of granitoids. From the 2nd crustal serie up to the medium temperature C-A serie the complexes show a regular shift in their chemical composition which became progressively richer in Sr and depleted in Rb. The highly differentiades hypersolvus Serra do Carambei granite is strongly enriched in Rb and impoverish in Ba with respect to the Itu and the Graciosa complex which itself is slighly more depleted in Sr than the Itu granite.

    In the State of Minas Gerais, the Secondary Reference Viva Vida Centers (CVVRS) are one of the strategies deployed to tackle the problems in child health. This study sought to evaluate pediatric care provided in a CVVRS, using the guidelines defined when it was set up as a benchmark. A quantitative-qualitative approach was adopted, which included a cross-sectional study with stratified random sampling of 385 medical records of children registered with the program between 2007 and 2009, and analysis of focus groups with strategic actors of the initiative. There were divergences between the user profiles and the target audience in terms of age, hometown and clinical characteristics. Access and use of the service differed depending on the town, due to problems of misinformation concerning the proposal, difficulty of transportation and the fragility of the health network. The centers are considered an innovative and important initiative for the expansion and organization of the health network, though the intended logic is not effectively seen in practice. Interventions for articulation between the network services and adaptation of the agreed guidelines to the regional specificities are necessary.

    Soil contamination by radionuclides, heavy metal, pesticides, among others, threatens ecosystems and human health. Environmental monitoring bodies and agencies need reference values for these contaminants in order to assess the impacts of anthropogenic activities on soil contamination. Quality Reference Values (QRVs) reflect the natural concentrations of contaminants in soils without anthropic interference and must be regionally established. The aim of this study was the determination of natural concentrations and quality reference values for U and Th in soils from Minas Gerais State, Brazil. A large variation of the natural activity concentration of these radionuclides in soil was observed. The QRV for U was 86.5 Bq kg"-"1 and 90.81 Bq kg"-"1 for Th. Statistical analysis showed that the two elements have a positive correlation with the clay and organic matter content in soil, and with the soil orders Ultisol and Inceptisol. Uranium shows a strong correlation with As, Sb, Se and Hg, while Thorium does not show correlation with any of the trace elements. (author)

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

    Visceral leishmaniasis has been notified in nearly all states of Brazil, and particularly in the north of Minas Gerais, where the disease is endemic. The aim of this study was to detect natural infection of Lutzomyia longipalpis and, through the PCR/RFLP technique, identify Leishmania species found in sandflies in the municipality of Janaúba. Using light traps, 1,550 females of L. longipalpis were caught and grouped into pools of 10 specimens to be subjected to DNA extraction and amplification, by means of generic PCR and cacophony. Out of the 155 pools, six were positive for Leishmania sp., and thus the infection rate in the municipality was 3.9%. Through PCR/RFLP, the digestion pattern among the positive samples was found to be similar to that of the reference strain of Leishmania chagasi (MHOM/BR/74/PP75). The detection of natural infection associated with studies on the epidemiology of visceral leishmaniasis suggests that L. longipalpis is involved in transmission of L. infantum chagasi in Janaúba, particularly in areas of intense transmission of visceral leishmaniasis.

    Factors associated with paid work were examined in a probabilistic sample of 3,320 adults (50-69 years) in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. Prevalence of paid work was 62.8% in men and 35.8% in women. For both men and women, paid work was positively associated with schooling and negatively associated with self-rated health. The probability of having paid work was higher for single women and those who knew someone that had suffered discrimination at the workplace. For men, prevalence of paid work varied from 67.2% in those with ≥ 8 years of schooling and better self-rated health, as compared to 37.8% in those with less schooling and poor self-rated health (PR = 0.56; 95%CI: 0.37-0.87). In women, the corresponding prevalence rates were 42.1% and 3.6% (PR = 0.09; 95%CI: 0.03-0.26). For women with little schooling and poor self-rated health, the likelihood of having paid work was ten times lower than for their male counterparts.

    Full Text Available Allozyme, microsatellite and random amplified polymorphic DNA (RAPD molecular markers were used to investigate the within and between population genetic variability and between population genetic differentiation of the Brazilian stingless bee uruçu amarela (nominally Melipona rufiventris Lepeletier, 1836 present in savanna and Atlantic forest habitats of the Brazilian state of Minas Gerais (MG. We found low levels of within population variability, although there were a large number of private alleles that specifically characterized these populations. The F ST values indicated a high level of genetic diversity between populations. Analysis of molecular variance (AMOVA showed a high degree of population differentiation between the savanna and Atlantic forest habitats, confirmed by population pairwise F ST data. Principal coordinates analysis and unweighted pair-group method using an arithmetic average (UPGMA dendrograms also confirmed that in Minas Gerais the savanna populations (M. rufiventris were genetically distinct from those present in the Atlantic forest (M. mondury. In addition, populations from locations near the towns of Dom Bosco and Brasilândia de Minas were genetically different from those collected in other localities in the savanna. Our data indicate that populations of uruçu amarela found in the savanna and Atlantic forest habitats of Minas Gerais state should be treated separately for conservation purposes and that special attention should be given to the populations found in the region of Dom Bosco and Brasilândia de Minas until their taxonomic status is clarified.

The research had a qualitative, exploratory, approach, the method used was case study method with analysis of documents and electronic form answers. Four companies were surveyed and the results show their relationship policies are based on business strategies, observing specifics issues of their position in the agribusiness system, and the culture of Minas Gerais does not affect these definitions. Nevertheless, in daily interactions cultural traits in commercial relationships were identified and they are used to adjust activities and relationships. It is suggested that the traits of the culture of the Minas Gerais State should be observed in the construction of external relations of these companies within a systemic vision which gives priority to dialogue and adaptation

    New geochronological data (Rb/Sr, Pb/Pb) for the Amparo and Pinhal Complexes, southern State of Minas Gerais and adjacent areas of the State of Sao Paulo are presented and discussed with respect to other lithostratigraphic complexes which there occur. Among the different complexes considered, 4 are composed mainly by rock belonging to typical infrastructure associations. They are the Barcelona, the Guaxupe, the Amparo and the Pinhal complexes. The Barbacena Complex is a typical gray gneiss complex and geochronological data by different methods confirm its Archean age. The Guaxupe Complex is composed mainly by different types of charnockitic rocks and an Archean age is assumed on geotectonic basis due to its neighboring association with the gray gneiss/greenstone belt, a though confirming geochronological data are still missing, a normal feature in this type of mobile belts which generally show a complex, polycyling evolution. Geochronological data by different methods on diverse rock types indicates that the Amparo and Pinhal complexes are respectively of Lower an Upper proterozoic age. Geochronological, geological and petrographic data reveal that both complexes are composed mainly by 3 basic rock associations: a-mainly derived magmatic rocks including mafic/ultramafic ones as well as calc-alkaline, subalcaline and even alkaline granitoids; b-orthogneisses, migmatites and crustal granites derived by metamorphic processes acting on older, pre-existing rocks; corthogneisses and migmatites resulting from metamorphic processes acting on magmatic rocks intruded during the same tecto-metamorphic cycle during which its transformation took place. The results suggest a polycyclic evolution by successive tecto-metamorphic events which affected the older rocks of the considered are either by the reworking of enclosing rocks around pericratonic continental main magmatic arcs or by the remobilisation of older basement rocks during continental collisions.

    The subcircular Mid-Cretaceous Pocos de Caldas alkaline massif, states of Minas Gerais and Sao Paulo, southern Brazil, covers over 800 Km 2 , and has as its main rock types phonolites and nepheline syenites, with subordinate amounts of pyroclastic rocks. Nepheline syenites consist mainly of K-feldspar, nepheline and pyroxene, varying both in texture and 'rare-metal silicates' content. A useful petrographic division is that which classifies the rocks into agpaitic and non-agpaitic (miaskitic or intermediate) types. The latter varieties, characterized by the absence of rare-metal silicates, are predominant by far; agpaitic types are easily recognized by the presence of eudialyte and other rare-metal silicates. Both petrographic and, as far as possible, structural descriptions as well are given for most of the mapped nepheline syenite bodies; many bodies show subhorizontal or moderately-dipping contacts with their country rocks. Chemically, these rocks show, on the whole, high alkaline contents (12-15%) and commonly very high K 2 O abundances. Chemical as well as additional isotopic and geochronological (Rb/Sr) data suggest that the asthenosphere is the source of parental magmas for the Pocos de Caldas nepheline syenites. The same arguments are used to reject, as unlikely, the magmatic activity interval (over 30 m.y.) given by previously published K/Ar ages. Simple structural models of the crust lithosphre in the Parana Basin area, coupled with the westward plate movement, suggest that irregularities at the asthenosphere-lithosphere decoupling surface are probable sites for melting of asthenospheric (and lithospheric) rocks induced by pressure relief.

Factors that influence the safety of blood transfusion include technical skill and knowledge in hemotherapy mainly obtained by the qualification and training of teams. This study aimed to investigate the relationship between professional categories working in transfusion services of the public blood bank network in the State of Minas Gerais and their performance in proficiency tests. This was an observational cross-sectional study (2007-2008) performed using a specific instrument, based on evidence and the results of immunohematology proficiency tests as mandated by law. The error rates in ABO and RhD phenotyping, irregular antibody screening and cross-matching were 12.5%, 9.6%, 43.8% and 20.1%, respectively. When considering the number of tests performed, the error rates were 4.6%, 4.2%, 26.7% and 11.0%, respectively. The error rates varied for different professional categories: biochemists, biologists and biomedical scientists (65.0%), clinical pathology technicians (44.1%) and laboratory assistants, nursing technicians and assistant nurses (74.6%). A statistically significant difference was observed when the accuracy of clinical pathology technicians was compared with those of other professionals with only high school education (p-value < 0.001). This was not seen for professionals with university degrees (p-value = 0.293). These results reinforce the need to invest in training, improvement of educational programs, new teaching methods and tools for periodic evaluations, contributing to increase transfusion safety and improve hemotherapy in Brazil.

    Full Text Available Oogenesis involves a sequense of transformations which are undergone by female germ cells. These cells change into oogonias and then into mature oocytes. Sexually mature females were collected monthly, during one year, from the Rio Sapucaí, tributary of the Rio Grande, which is part of the Furnas Reservoir system in the state of Minas Gerais. The observed material showed that oogonias were small spherical cells, had a big spherical nucleus, with a single nucleolus, and weakly stained cytoplasm with eosinophilic granules (FG stained, which indicate their protein content. The primary oocytes showed a big basophilic nucleus, with a large peripheral nucleolus, and several smaller nucleoli. They show a reduced cytoplasmic content. The previtellogenic oocytes presented voluminous cytoplasm and nucleus with several small peripheral nucleoli. The oocytes underwent vitellogenesis with the development of the zona radiata and the follicle cells. The zona radiata had two layers, the outer and the inner, which showed its protein content when stained with CM and FG techniques. TB pH 2.5 and pH 4.0 staining showed that oocytes undergoing vitellogenesis presented weakly stained cytoplasm and peripheral cytoplasmic vesicles. The follicle cells that were squamous became cuboidal. In mature oocytes, the yolk granules that filled the cytoplasm became green and blue when stained with FG and CM techniques, indicating their protein content. The perivitclline region showed rosy stained vesicles (TB pH 2.5 and pH 4.0 spread among the weakly stained peripheral vesicles, which seemed to be the cortical alveoli. The zona radiata cells, CM and FG stained, still showed two layers like the oocytes from the previous stage, but thicker.

    Leishmania spp. are distributed throughout the world, and different species are associated with varying degrees of disease severity. In Brazil, Leishmania transmission involves several species of phlebotomine sand flies that are closely associated with different parasites and reservoirs, and thereby giving rise to different transmission cycles. Infection occurs during the bloodmeals of sand flies obtained from a variety of wild and domestic animals, and sometimes from humans. The present study focused on detection of Leishmania DNA in phlebotomine sand flies from a cave in the state of Minas Gerais. Detection of Leishmania in female sand flies was performed with ITS1 PCR-RFLP (internal transcribed spacer 1) using HaeIII enzyme and genetic sequencing for SSUrRNA target. The survey of Leishmania DNA was carried out on 232 pools and the parasite DNA was detected in four: one pool of Lutzomyia cavernicola (Costa Lima, 1932), infected with Le. infantum (ITS1 PCR-RFLP), two pools of Evandromyia sallesi (Galvão & Coutinho, 1939), both infected with Leishmania braziliensis complex (SSUrRNA genetic sequencing analysis), and one pool of Sciopemyia sordellii (Shannon & Del Ponte, 1927), infected with subgenus Leishmania (SSUrRNA genetic sequencing analysis). The present study identified the species for Leishmania DNA detected in four pools of sand flies, all of which were captured inside the cave. These results represent the first molecular detection of Lu cavernicola with Le infantum DNA, Sc sordellii with subgenus Leishmania DNA, and Ev sallesi with Leishmania braziliensis complex DNA. The infection rate in females captured for this study was 0.17%. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America. All rights reserved.

    Full Text Available ABSTRACT The objective of this study was to analyze the relationship between aspects related to financial management and scale of production with quality traits (total bacteria count - TBC; somatic cell count - SCC and composition (protein, fat, lactose, total solids, and non-fat solids of refrigerated bulk tank milk from 100 dairy farmers located in the south of Minas Gerais state, Brazil, by application of a semi-structured questionnaire. Dairy farmers were categorized according to the daily milk production: small (lower than 150 L; medium (151 to 500 L; and large (higher than 501 L. Chi-square tests and identification of possible relative risks between financial aspects and current regulation standards (Normative Instruction No. 62 of December 29, 2011, Ministry of Agriculture, Livestock and Supply associated to TBC (higher 300,000 CFU/mL and SCC (higher than 500,000 cells/mL means from bulk tank milk among different milk scales productions were performed. Bulk tanks milk composition met the legislation standards and had not differ between scales of production; however, SCC means within all scales, and TBC of small farmers had not attended the legislation standards and differences were identified (P ≤ 0.05. Regarding the financial management aspects, most farmers had no control over incomes, costs, nor calculated milk production cost, with decreased incidences as scale of production increased. Chi-square tests identified that producers that had no concern about milk quality payment bonuses had TBC means 2.95 times more likely (P ≤ 0.05 to be above the current regulations. Small dairy farmers had a greater negligence of the costs management and hygienic milk production as compared to medium and large farmers.

    Among the neglected tropical diseases (NTDs), schistosomiasis and the three main soil-transmitted helminthiases (STHs), i.e., ascariasis, trichuriasis and hookworm infection, represent the most common infections in developing countries. In Brazil, there is a lack of epidemiological data in many parts of the country, which favors the unawareness of the real situation concerning these diseases. Due to this, we investigated the occurrence of schistosomiasis and STHs in a region of Minas Gerais State, Brazil. One stool sample was collected from 503 individuals, whose ages ranged from 0.1 to 91.2 years, and screened using both the Kato-Katz and the Formol-Ether methods. In parallel, a malacological survey was carried out in the main water bodies of the district, and Biomphalaria susceptibility assays and kernel-based techniques were also performed. No individual was found infected with Ascaris lumbricoides or hookworm. Schistosoma mansoni was the most common parasite found (1.6%). The prevalence was higher in males and the chance of acquiring the disease increased by 43.35 times with contact with a body of water. None of the Biomphalaria tenagophila and B. glabrata specimens were found naturally infected, but B. glabrata was highly susceptible to infection with Schistosoma mansoni. Using kernel-based techniques, clusters of Biomphalaria were found near the households where the infected individuals lived. Schistosomiasis was the most prevalent parasitic infection found. Our findings show that the occurrence of this disease has been underestimated by the local health care service, and highlight the importance of epidemiological surveillance in areas of low prevalence for schistosomiasis. © The Author 2014.

    Intraerythrocytic protozoan species of the genera Theileria and Babesia are known to infect both wild and domestic animals, and both are transmitted by hard-ticks of the family Ixodidae. The prevalences of hemoprotozoa and ectoparasites in 15 free-living Mazama gouazoubira, two captive M. gouazoubira and four captive Blastocerus dichotomus from the State of Minas Gerais, Brazil, have been determined through the examination of blood smears and the use of nested polymerase chain reaction (nPCR). The cervid population was inspected for the presence of ticks and any specimens encountered were identified alive under the stereomicroscope. Blood samples were collected from all 21 animals, following which blood smears were prepared, subjected to quick Romanowsky staining and examined under the optical microscope. DNA was extracted with the aid of commercial kits from cervid blood samples and from tick salivary glands. The nPCR assay comprised two amplification reactions: the first was conducted using primers specific for a 1700 bp segment of the 18S rRNA gene of Babesia and Theileria species, whilst the second employed primers designed to amplify a common 420 bp Babesia 18S rRNA fragment identified by aligning sequences from Babesia spp. available at GenBank. The ticks Amblyomma cajennense, Rhipicephalus microplus and Dermacentor nitens were identified in various of the cervids examined. Of the animals investigated, 71.4% (15/21) were infected with hemoprotozoa, including Theileria cervi (47.6%), Theileria sp. (14.3%), Babesia bovis (4.8%) and Babesia bigemina (4.8%). However, only one of the infected wild cervids exhibited accentuated anaemia (PCV=17%). This is first report concerning the occurrence of Theileria spp. in Brazilian cervids.

    Children with Hb S (HBB: c.20A > T)/hereditary persistence of fetal hemoglobin (Hb S/HPFH) have a mild clinical phenotype, but some complications have been reported. The natural history of Hb S/HPFH in children from the State of Minas Gerais, Brazil newborn cohort is described. Clinical and hematological data regarding participants' phenotypes were retrieved from medical records. The HPFH-1, HPFH-2, and HPFH-3 and α-thalassemia (α-thal) deletions were detected by gap-polymerase chain reaction (gap-PCR). Thirteen children were included, nine (69.2%) had the Hb S/HPFH-2 deletion, and four (30.8%) had Hb S/HPFH-1 deletion; 11 children (84.6%) had αα/αα, and two (15.4%) carried the αα/-α(3.7) (rightward) deletion. The mean concentration of total hemoglobin (Hb) and Hb F was 12.52 ± 0.56 g/dL and 42.31% ± 1.97%, respectively. Mild microcytosis and hypochromia were observed. We found acute clinical manifestations of sickle cell disease, such as acute chest syndrome (ACS) and acute pain crisis in four children; nine (69.2%) children were completely asymptomatic during the follow-up period. All children were classified as having low-risk transcranial Doppler (TDC). In conclusion, children with Hb S/HPFH have a mild clinical phenotype of sickle cell disease, although acute clinical manifestations may occur. High Hb F levels and absence of anemia are common hematological characteristics.

    The adequacy of facilities and the individual securities in their different age groups is importance to ensure greater functionality to them, allowing full development of daily activities. For this to occur more efficiently it is necessary the use of ergonomics which can ensure more comfort and safety for end users of products and spaces. The present study aimed to measure body dimensions of a representative sample of children aged 6 to 11 years old, children of graduate and pos graduate students, faculty and staff of the Federal University of Vicosa and also residents of the city of Vicosa, State of Minas Gerais, Brazil, coming from different municipalities of State of Minas Gerais, to organize a database that will provide the furniture industry, anthropometric variables more appropriate to design products for both the leisure activities, and for the school sector. To realize this research we used the methodology proposed by the authors Panero and Zelnik, based on samples distributed in six age groups, and providing a measurement of 10 variables. By applying the methodology to the field was possible to compare the observed data, with the tables of the aforementioned authors. The main results revealed a significant variation of the 10 variables analyzed, and it is believed that this variation could lead to possible flaws in the designs of products that use the data from these authors. The completion of the study provided data on Vicosa considered more appropriate for the design of products and environments for the population of the study, considering age and region, of Brazil (State of Minas Gerais) and it is believed that the future may expand to the Brazilian population, with the progress of study of this nature.

This was a cross-sectional study of 310 patients enrolled in two public health centers in Belo Horizonte, Minas Gerais State, Brazil. Delayed ART initiation was defined as starting treatment with a CD4 count lower than 200 cells/mm³ or clinical symptoms of severe immunodepression at the time of first antiretroviral prescription. The majority of participants were males (63.9%, had no health insurance (76.1%, and started ART less than 120 days after the first medical visit (75.2%. The proportion of delayed ART initiation was 68.4%. Unemployment, referral by a health professional for HIV testing, fewer than two medical visits in the six months prior to ART initiation, and time between first medical visit and ART initiation less than 120 days were independently associated with the outcome. Our results suggest that every patient 13 to 64 years of age should be offered HIV testing, which could increase the rate of early HIV diagnosis, and thus patients that tested positive could benefit from timely follow-up and antiretroviral therapy.

    Workers that segregate recyclable garbage are daily exposed to unhealthy work conditions which can have a more intense negative effect with aging of the garbage collector. A population of garbage collectors from Governador Valadares, Minas Gerais, Brazil answered a semi-structured questionnaire regarding the presence or absence of labor pain, pain intensity, living conditions, access to health services, occurrence of accidents at works and degree of personal satisfaction. These variables were correlated with the age of the workers. It was observed that pain is not associated to age increase and that it doesn't affect the degree of personal satisfaction of the studied population. The education degree was negatively related with age. The youngest garbage collectors presented a lower degree of life satisfaction. The age of the workers doesn't have any association with the occurrence of accidents at work and dwelling type.

Modelos de estimativa de RFA a partir da Radiação Global (Rg são extremamente úteis, visto que a Rg é convencionalmente medida nas estações meteorológicas. Assim, analisou-se a variabilidade sazonal da relação RFA/Rg em cinco áreas localizadas na bacia do rio Doce, Estado de Minas Gerais, considerando-se os períodos secos e chuvosos dos anos de 2001 a 2004. As relações RFA/Rg obtidas para os períodos secos e chuvosos, assim como para todos os dados, apresentaram concordância com as relações determinadas por diversos pesquisadores em diferentes áreas do mundo. Analisando-se os resultados, constatou-se que, de maneira geral,as relações RFA/Rg tendem a ser superiores durante os períodos chuvosos comparativamente aos secos. Por este estudo, pôde-se concluir que existe variação interanual desta relação, demonstrando assim a necessidade de se considerar esta variabilidade para estimaradequadamente a RFA a partir da Rg. The knowledge of the Photosynthetically Active Radiation (PAR is important to different areas of vegetal physiology and agricultural sciences.

    Soil contamination by radionuclides, heavy metal, pesticides, among others, threatens ecosystems and human health. Environmental monitoring bodies and agencies need reference values for these contaminants in order to assess the impacts of anthropogenic activities on soil contamination. Quality Reference Values (QRVs) reflect the natural concentrations of contaminants in soils without anthropic interference and must be regionally established. The aim of this study was the determination of natural concentrations and quality reference values for U and Th in soils from Minas Gerais State, Brazil. A large variation of the natural activity concentration of these radionuclides in soil was observed. The QRV for U was 86.5 Bq kg{sup -1} and 90.81 Bq kg{sup -1} for Th. Statistical analysis showed that the two elements have a positive correlation with the clay and organic matter content in soil, and with the soil orders Ultisol and Inceptisol. Uranium shows a strong correlation with As, Sb, Se and Hg, while Thorium does not show correlation with any of the trace elements. (author)

    Full Text Available The objective was to analyze the surface water quality on the highlands of the Conquistinha river basin, an area influenced by human activities mostly due to proximity of the Uberaba city boundaries through integrated water resources supported on geoprocessing. The water sampling campaign occurred by month, from October 2012 to September 2013 at three surface water spots strategically located to detect the human influence. Remote sensing technique of image classification process was used to produce the Land Use/Land Cover (LULC map highlighting five categories on July 2011: 42.07% on crops, 29.97% on pasture, 20.17 on human activity, 7.7% on forest and 0.09% on water. The Water Quality Index (WQI was used to evaluate its categorize water quality. All water quality results, by spatial and time approaches, indicate bad and very bad WQI according to Minas Gerais Institute to Water Management. Integrated analysis of land cover and water parameters suggest the human presence influences on water quality worsening. Urban planning about the city growing direction must be done with care over this particular region once the environmental quality especially on water resources is now compromised.

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

    Full Text Available ABSTRACT: The frozen açaí ( Euterpe oleracea Mart. pulp market has had acceptable development and presents great market potential due to its high nutritional level and fruit's seasonality. However, due to the lack of standards for all types of fruit, products without uniformity are in the market. This study aimed to evaluate frozen açaí pulp belonging to different trademarks related to chemical, physicochemical, and microbiological characteristics. Regarding the total titratable acidity (TTA and pH, two trademarks from Pará and two from Minas Gerais were rejected compared with the current legislation. It was observed that K (1,253.6mg 100 g-1, Ca (312mg 100g-1, Mg (178mg 100g-1, and P (145mg 100g-1 were the main minerals reported in the analyzed samples. Fe showed an average content from 9.65mg 100g-1 to 22.66mg 100g-1. As for microbiological characteristics, the counts for E. coli were in compliance with legislation. Counts of mesophilic aerobic, filamentous fungi, and yeasts showed variations in the results. The count of coagulase-positive S. aureus met the standards [102 Colony Forming Units (CFU g-1]; and presence of Salmonella sp. in a trademark was detected among the six evaluated trademarks. The analyzed pulp of açaí showed total phenolics values ranging from 240.14mg AGE 100g-1 to 372.43mg AGE 100g-1, and anthocyanin total levels ranging from 12.05 to 24.98mg 100g-1. The obtained physicochemical and microbiological results indicated the need for immediate implementation of Good Manufacturing Practices; conversely, the frozen pulp of açaí showed considerable antioxidant potential.

    Full Text Available Knowledge of potential reservoirs of Leishmania spp. in an anthropic environment is important so that surveillance and control measures can be implemented. The aim of this study was to investigate the infection by Leishmania in small mammals in an area located in Minas Gerais, Brazil, that undergoes changes in its natural environment and presents autochthonous human cases of cutaneous leishmaniasis (CL and visceral leishmaniasis (VL. For the capture of the animals, Sherman and Tomahawk traps were used and distributed in the peridomicile of houses with reports of autochthonous cases of CL or VL. Six catches were carried out on two consecutive nights with intervals of two months during one year and samples of spleen, liver, tail skin, ear skin and bone marrow of the animals were obtained. Parasitological and molecular methods were used to detect the infection. Identification of the Leishmania species was performed by PCR RFLPhsp70. Twenty five animals of four species were captured: ten Rattus rattus, nine Didelphis albiventris, five Cerradomys subflavus and one Marmosops incanus. In the PCR-hsp70, five animals were positive (20%. The Leishmania species identified in PCR-RFLPhsp70 were: Leishmania braziliensis in D. albiventris (2, C. subflavus (1 and R. rattus (1 and Leishmania infantum in R. rattus (1. The highest positivity rate for L. braziliensis was obtained in the liver samples. The spleen was the only tissue positive for L. infantum. It was isolated in culture medium L. braziliensis from two samples (liver and spleen of R. rattus. This is the first record of isolation of L. braziliensis from R. rattus in the southeastern region of Brazil. These results are relevant to the knowledge of the epidemiology of leishmaniasis in the region, mainly in the investigation of the presence of hosts and possible reservoirs of the parasite.

    The Caldas Ore Treatment Unit (UTM-Caldas), located at the municipality of Caldas (Minas Gerais-Brazil), was a site for the exploration and treatment of uranium between 1982 and 1995. The area is located in the Alcalino Complex of Poços de Caldas, a geologically peculiar region, composed of alkaline igneous rocks with exotic minerals, some rich in rare earth elements (REE). The UTM-Caldas uranium deposit was defined as a U, Th, Zr, Mo and REE mineralization. The objective of the present study was to evaluate the distribution of REEs in river sediments adjacent to UTM-Caldas and to verify if effluents from the mine are interfering in the concentration of REEs in these sediments. To develop the research, five samples were collected in 2011, including sediments from the Soberbo river, the waste dam and the tank of radio precipitation. The samples were prepared in the Sedimentology Laboratory of the Center for the Development of Nuclear Technology (CDTN), where the rocks and tailings were crushed, ground and pulverized while the sediments were sieved and an aliquot of the silt-clay fraction was separated for analysis at the CDTN. The analytical method employed was Neutron Activation Analysis (ANA), method k 0 . The samples were irradiated in the TRIGA MARK I IPR-R1 research reactor, and the REEs identified by gamma-spectrometry in the Neutron Activation Laboratory (LAN-CDTN). The results showed a distribution model of the REEs in the study area, which may be useful in evaluating of the environmental impacts of effluents from UTM-Caldas, now in the process of decommissioning

    This study aimed to assess raw milk consumption habits in the urban population of Viçosa, Minas Gerais, Brazil, and the microbiological safety and quality of the fluid milk available in retail sales outlets in the same region. A simplified questionnaire regarding raw milk consumption was applied to the persons responsible for food acquisition in 411 residences. The regular consumption of raw milk was observed by 18.5% of the interviewers, and lack of knowledge of possible risks related to this food product. Microbiological safety and quality were assessed for raw (n=69), pasteurized (n=80), and ultra-high-temperature (UHT)-treated milk (n=80) by analyzing the counts of mesophilic aerobes, coliforms, and Escherichia coli, and detection of Listeria monocytogenes and Salmonella spp.; raw milk samples were also subjected to enumeration of coagulase-positive Staphylococcus. Concerning raw milk, 59.4% of the samples were considered as produced in inadequate hygienic conditions, 5.8% of the samples presented counts of coagulase-positive Staphylococcus lower than 100 colony-forming units (CFU)/mL, and no samples presented with positive results for L. monocytogenes or Salmonella spp. All pasteurized and UHT milk samples presented with low counts of mesophilic aerobes and coliforms, while L. monocytogenes and Salmonella spp. were absent. The data demonstrated that raw milk was consumed by the population studied. Despite the absence of potential hazards, raw milk was of poor hygienic quality, in contrast with the processed fluid milk available in retail sales outlets that was safe and of good hygienic quality, highlighting the suitability of pasteurized and UHT milk for human consumption.

    Full Text Available The objective of this study was to test the hypothesis that the distribution of tree species in a fragment of submontane seasonal semideciduous forest, a buffer zone in the Parque Estadual do Rio Doce, Minas Gerais, is influenced by geomorphological and weather and soil variables, therefore it can represent a source of information for the restoration of degraded areas where environmental conditions are similar to those of the study area. A detailed soil survey was conducted in the area by sampling three soil profiles per slope segment, totaling 12 profiles. To sample the topsoil, four composite samples were collected from the 10-20 cm layers in each topographic range totaling 16 composite samples. In the low ramp and the lower and upper concave slopes, the texture ranged from clay to sandy-clay. The soil and topographic gradient was characterized by changes in the soil physical-chemical properties. The soil in the 10-20 cm sampled layer was sandier, slightly more fertile and less acid in the low ramp than the clayer soil, nutrient-poor and highly acid soil at the top. The soil conditions in the lower and upper slope of the sampled layers, in turn, were intermediate. The P levels were limiting in all soils. The species distribution along the topographic gradient was associated with variations in chemical fertility, acidity and soil texture. The distribution of Pera leandri, Astronium fraxinifolium, Pouteria torta, Machaerium brasiliense and Myrcia rufipes was correlated with high aluminum levels and to low soil fertility and these species may be indicated for restoration of degraded areas on hillsides and hilltops in regions where environmental conditions are similar. The distribution of Pouteria venosa, Apuleia leiocarpa and Acacia polyphylla was correlated with the less acid and more fertile soil in the environment of the low ramps, indicating the potential for the restoration of similar areas.

    The transmission of Leishmania involves several species of sand flies that are closely associated with various parasites and reservoirs, with differing transmission cycles in Brazil. A study on the phlebotomine species composition has been conducted in the municipality of Divinópolis, Minas Gerais, Brazil, an endemic area for cutaneous leishmaniasis (CL), which has intense occurrence of visceral leishmaniasis (VL) cases. In order to study the sand flies populations and their seasonality, CDC light traps (HP model) were distributed in 15 houses which presented at least one case of CL or VL and in five urban parks (green areas). Collections were carried out three nights monthly from September 2010 to August 2011. A total of 1064 phlebotomine specimens were collected belonging to two genera and seventeen species: Brumptomyia brumpti, Lutzomyia bacula, Lutzomyia cortelezzii, Lutzomyia lenti, Lutzomyia sallesi, Lutzomyia longipalpis, Lutzomyia migonei, Lutzomyia intermedia, Lutzomyia neivai, Lutzomyia whitmani, Lutzomyia christenseni, Lutzomyia monticola, Lutzomyia pessoai, Lutzomyia aragaoi, Lutzomyia brasiliensis, Lutzomyia lutziana, and Lutzomyia sordellii. L. longipalpis, the main vector of Leishmania infantum in Brazil, was the most frequent species, accounting for 76.9% of the total, followed by L. lenti with 8.3%, this species is not a proven vector. Green and urban areas had different sand flies species composition, whereas the high abundance of L. longipalpis in urban areas and the presence of various vector species in both green and urban areas were also observed. Our data point out to the requirement of control measures against phlebotomine sand flies in the municipality of Divinópolis and adoption of strategies aiming entomological surveillance.

    Full Text Available INTRODUCTION: Within the context of transfusion safety, the immunohematological study of donors and recipients of blood products is currently the most fragile link in the transfusion chain of the public blood bank network of Minas Gerais. OBJECTIVE: The objective of this work was to provide a critical and situational overview of the physical and operational infrastructure of the transfusion services in the state. Method: This was an observational cross-sectional, evidence-based study covering 226 transfusion services; only 19 belong to the Hemominas Foundation and 207 are non-Hemominas transfusion services. The investigation involved the application of questionnaires and red cell panel tests. RESULTS: The results revealed considerable non-compliance with the national law and with the norms of Hemominas. These findings were obtained for the two groups studied; however the frequencies were higher among non-Hemominas transfusion services. CONCLUSION: The study provides information about the situation of the physical and operational infrastructure of transfusion services that may be used to help plan effective measures for improvement and serve as the basis for an evaluation of the impact of future interventions regarding the quality, reliability and safety of transfusions. As primordial factors, we propose compliance with the law, qualified personnel and investment in further qualifications, a review of training methods, and more rigorous inspection of transfusion services. As a suggestion, we propose the establishment of an External Quality Control Program in Immunohematology for the entire network of blood banks in the state and the adoption of the methods presented in this study as a tool to monitor transfusion service performance.INTRODUÇÃO: No contexto da segurança transfusional, o estudo imuno-hematológico do doador e do receptor de hemocomponentes é hoje o elo mais frágil da cadeia transfusional na hemorrede pública de Minas Gerais

    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.INTRODUÇÃO: As crianças são importantes grupos de risco para infecções por helmintos e protozoários.

MÉTODOS: A frequência das manifestações clínicas de hipotireoidismo congênito foi analisada em relação aos níveis de hormônio estimulante da tireoide T4L (determinados por quimioluminescência, valores de referência de 0,3 a 5,0 µUI/mL e 0,8 a 1,8 ng/dL, respectivamente e idades ao diagnóstico e tratamento. Estudou-se 443 crianças, sendo 55,8% do sexo feminino e 95% delas com menos 60 dias de vida. RESULTADOS: Os sinais clínicos mais prevalentes foram: hérnia umbilical (51%, fontanela anterior ampla (50,3% e fontanela posterior aberta (47,2%. Hipotonia, macroglossia e sucção débil foram os sinais mais associados com a gravidade bioquímica da doença. Em 32,1% das crianças houve atraso na idade óssea ao diagnóstico. As medianas de TSH e T4L séricos foram 120 µUI/mL e 0,62 ng/dL, respectivamente. A mediana da idade de início de tratamento foi de 28 dias. CONCLUSÃO: Existem sinais clínicos precoces que sugerem o diagnóstico de hipotireoidismo congênito. Portanto, diante de uma criança com esses sinais, devem ser avaliados TSH e T4L séricos para confirmar ou excluir a doença, independentemente do resultado do teste de triagem. A idade de início de tratamento ainda foi elevada, mas o programa vem adotando estratégias para redução da mesma.OBJECTIVE: To evaluate the clinical profile of newborns with congenital hypothyroidism identified by the Newborn Screening Program of the State of Minas Gerais, Brazil, between 2000 and 2006.

Sixty-three samples were collected from five lentic and three lotic water bodies at the Espinhaço Mountain Range Biosphere Reserve (Minas Gerais State, Brazil. Anova and Tukey statistical tests were performed for Protista, Rotifera and Crustacea richness, whereas the abundance of Protista, Rotifera, Crustacea, Gastrotricha, Tardigrada and Nematoda was evaluated by percentage. Of the three methods, the Dredge is less indicated for different water bodies systems in which there is interest in analyzing various microinvertebrate groups. The Protista and Rotifera represent 80% of the total abundance and richness in the invertebrate community. In the ecosystems evaluated, all methods are relevant for Protistaanalysis; on the other hand, Crustacea analysis required the Jar method. Manual Removal and Dredge methods are appropriate for Rotifera analysis. Gastrotricha and Tardigrada abundance presented better results with the Jar method; Nematoda with the Dredgemethod. The three methods are appropriate for periphyton fauna sampling in both water body systems; nevertheless, it is important to be aware that for each fauna community in a specified ecosystem, there is a specific method for best performance.Os métodos “Jarra”, “Remoção Manual” e “Draga de Eckman modificada” foram avaliados para amostrar a fauna perifítica associada à macrófitas aquáticas.

Apesar da importância biológica da área, muitos grupos animais não foram estudados, como as vespas sociais, insetos que pertencem à ordem Hymenoptera, família Vespidae, e que desempenham importante papel ecológico em diferentes ecossistemas. O estudo foi conduzido nessa Unidade de Conservação em altitudes entre 1600 a 2200 m, no período de julho de 2013 a abril de 2014, durante vinte dias de amostragem, utilizando busca ativa e armadilhas atrativas para registro das espécies. Foram amostradas 22 espécies de vespas sociais distribuídas em sete gêneros. Número menor em relação a outros estudos do estado, o que, provavelmente, foi ocasionado pela elevada altitude. Houve uma predominância de ninhos com invólucro protetor e a espécie mais frequente foi Polybia fastidiosuscula Saussure, o que pode ser explicado pela melhor regulação térmica obtida pelo invólucro. Outras duas espécies frequentes foram Mischocyttarus drewseni Saussure e Mischocyttarus rotundicolis (Cameron que possuem ninhos sem invólucro, porém essas espécies possuem coloração escura, assim como o substrato utilizado para nidificação e isso poderia reter melhor a radiação solar.

This research aims to analyze, from the beneficiaries’s point of view of the Programme “Programa Crédito Solidário” (PCS in a town in the southern of Minas Gerais State, in levels of economic, social and political emancipation of those who benefit from this public policy. It becomes clear how this type of action represents a process of implementation and formulation of public projects in a paradoxical condition, because at the same time it promotes new alternatives for the development of small business from the Economia Solidária (Solidarity Economy, it alters to be rather weak in a context of economical, social and political emancipation of beneficiaries.   Keywords Public entrepreneurship; Solidarity economy; Emancipation.

    This paper analyses the associations between Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) on the prevalence of schistosomiasis and the presence of Biomphalaria glabrata in the state of Minas Gerais (MG), Brazil. Additionally, vegetation, soil and shade fraction images were created using a Linear Spectral Mixture Model (LSMM) from the blue, red and infrared channels of the Moderate Resolution Imaging Spectroradiometer spaceborne sensor and the relationship between these images and the prevalence of schistosomiasis and the presence of B. glabrata was analysed. First, we found a high correlation between the vegetation fraction image and EVI and second, a high correlation between soil fraction image and NDVI. The results also indicate that there was a positive correlation between prevalence and the vegetation fraction image (July 2002), a negative correlation between prevalence and the soil fraction image (July 2002) and a positive correlation between B. glabrata and the shade fraction image (July 2002). This paper demonstrates that the LSMM variables can be used as a substitute for the standard vegetation indices (EVI and NDVI) to determine and delimit risk areas for B. glabrata and schistosomiasis in MG, which can be used to improve the allocation of resources for disease control.

    The objective of this work is to study the environment contamination by mercury in the current sediments and alluvial plain sediments in the course of Muriaé River (between towns of Patrocinio de Muriaé (MG) – Itaperuna (RJ)) in Minas Gerais and Rio de Janeiro States where occurred the extraction of gold using the process of amalgamation by mercury during eighties and the beginning of the nineties. The methodology used was based in total and sequential extraction. The results in parts per billion (ng.g-1) showed that the total mercury ranged from 222,9 to 761,9 ng.g-1 in the current sediments et 233,6 to 2131,9 ng.g-1 in the alluvial plain sediments. Comparing theses values with the background of region (170 ng.g-1 to 365 ng.g-1) only two of the samples showed results according to this background. The others showed results above this interval. It was observed that when it comes to the availability of mercury to the aquatic environment and biota, 1% to 26,2% of the total mercury is in the exchangeable phase, easily available for the environment, 52,3% to 90,4 % is potentially available (in the oxidizable phase) and 0,2 % to 40 % is inert, imprisoned in the mineral's structure of the sediments ( residual phase)

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

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

In area 1, with a total population of 1,480 inhabitants, a study of the entire population was attempted. In areas 2, 3, and 4, due to the large number of inhabitants, a systematic sample by conglomerates was studied, of approximately 25 per cent of the population (family grouping of one in every four residences. The study consisted of an evaluation of the economic and sanitary conditions of the population, of contact with the local foci of transmission of schistosomiasis, of the frequency and intensity of infection by S. mansoni and of the relation between parasite load and the different clinical forms of the disease in different age groups. In parallel, a study was carried out of the intermediate hosts in each area and of the frequency of infection with S. mansoni cercariae. The prevalence of active S. mansoni infection was 60.8, 50.5, 63.1 and 46.6 per cent in areas 1, 2, 3 and, with a median egg elimination of 207, 77.6, 391 and 211 per gram, respectively. Progressive increases in frquency of infection of parasite load and of serious forms of the disease were observed from the first to the third decade in the areas of the Southeast Region and a later increase in the same parameters in the Northeast Region. Other correlations between clinical forms of the disease and age groups, sex, and ethnical origins of the patients, as well as frequency among the planorbids, were carried out.

    Full Text Available ABSTRACT In the Southern Espinhaço Mountain Chain and in the Upper Jequitinhonha Valley, magnetic soils, in different pedogenetic stages, are found to be forming over intrusions of basic lithology. The essential chemical and mineralogical properties of samples from magnetic soil profiles from those two physiographic environments in the state of Minas Gerais, Brazil, are reported. Three of the pedons (Rhodic Kandiustox – RKox, Rhodic Haplustox – RHox, and Typic Argiustoll - TAoll were identified as being indeed developed over basic rocks; the fourth pedon (Typic Haplustox - THox is currently forming on an acidic rock. Particle size and routine chemical analyses were performed on samples from all horizons of the four selected soil profiles. For a deeper insight into the dominant mineralogy of each diagnostic soil horizon, the elemental contents, expressed in terms of the corresponding metal cation oxides, namely Fe2O3, Al2O3, and MnO2, were obtained from digesting the whole soil samples with sulfuric acid. A similar chemical analytical procedure was performed for the residual solid extracts obtained from attacking the whole soil materials with mixtures of (i dithionite - citrate - bicarbonate and (ii oxalate - oxalic acid. The soil samples were also analyzed by Mössbauer spectroscopy at room temperature (~298 °K in an attempt to better identify the main magnetic iron oxides. Maghemite (δFe2O3 was found in all samples and magnetite (Fe3O4 was identified only for the sample from the Typic Argiustoll. The pedogenetic loss of silica and consequent accumulation of iron and aluminum oxides along the profile are found to be somehow correlated to the weathering sequence in the soils forming on basic rocks: TAoll < RKox < RHox.

    Giardiasis and soil-transmitted helminthiasis (STH) are parasitic diseases that are among the major health concerns observed in economically disadvantaged populations of developing countries, and have clear social and environmental bases. In Brazil, there is a lack of epidemiologic data concerning these infections in the study area, whose inhabitants have plenty of access to health care services, including good dwelling and adequate sanitary conditions. In this survey we investigated the risk factors for giardiasis and STH in three municipalities with good sanitation, situated in Minas Gerais state, Brazil. A cross-sectional survey was conducted in the municipalities of Piau, Coronel Pacheco and Goianá, in both urban and rural areas. The fieldwork consisted of a questionnaire and the examination of 2,367 stool samples using the Hoffmann, Pons and Janer method. Of all individuals from the population sample, 6.1% were found infected with the parasitic diseases included in this work. Hookworm infection was the most prevalent disease, followed by giardiasis, trichuriasis and ascariasis. Infection was more prevalent in males (8.1%, p < 0.001; odds ratio [OR] = 1.975) and in individuals living in rural areas (8.6%, p = 0.003; OR = 1.693). Multivariate analysis showed that variables such as inadequate sewage discharge (p < 0.001), drinking of unsafe water (p < 0.001), lack of sanitary infrastructure (p = 0.015), and host sex (p < 0.001) were the risk factors more strongly associated with infection status (95% confidence interval [CI]). In this study we demonstrate that giardiasis and STH still persist, infecting people who have good housing conditions and free access to public health care and education.

Chemical, mineralogical and micromorphological attributes of ten soil profiles along two transects in the quartzitic domains of the Ibitipoca State Park, Minas Gerais State, Brazil, were studied in relation to their pedogenesis. At local level, soil formation is more closely associated with litho-structural elements (lithology, faults and fractures, than with topographical variations. The soils are Al-saturated (> 60% at the surface, negatively charged, and markedly dystrophic. The existing CEC is almost entirely attributable to the organic matter contribution, in view of the very low clay fraction activity. Results revealed the marked presence of low crystallinity Fe-forms, commonly found in high altitude vegetation, where organic matter accumulation inhibits Fe and Al oxide crystallization. All soils are kaolinitic, even the ferrocarbic Spodosol, and some contain 2:1 clays such as illite and hydroxy-interlayered vermiculite, indicating their resistance to weathering under the present pedoenvironmental conditions. Micromorphological analyses of the Spodosol presented typical features of a podzolization process: predominant quartz grain interbedded between polymorphic organic matter aggregates at the surface, single grain structure and presence of "ortstein" in the spodic horizon (Bs, formed by organic-mineral and mineral materials, monomorphic and fractured, with co-precipitated amorphous Al, Si and Fe

    Full Text Available The Glória quartz-monzodiorite, one of the mafic plutons of the Paleoproterozoic Mineiro belt, is intrusive into banded gneisses, amphibolites, schists and phyllites of the Rio das Mortes greenstone belt, in the southern portion of the São Francisco Craton, State of Minas Gerais, Brazil. The Glória quartz-monzodiorite yields a SHRIMP U-Pb zircon age of 2188 ± 29 Ma, suggesting a tectonic relationship with the pre-collisional phase of the Mineiro belt. According to the Nd isotopic evidence (epsilonNd(T = -3.4; T DM = 2.68 Ga the original magmas was formed by a mixture among Archean crustal material and Paleoproterozoic juvenile magma. The Glória quartz-monzodiorite shows metaluminous and calc-alkaline tendency with intermediate K content, comparable to that of volcanic-arc rocks. The primary mineralogical assemblage was partly modified by metamorphism, dated between 2131-2121 Ma in nearby coeval plutons. Such metamorphism is significantly older than the reported metamorphic episodes of the Mineiro belt in the Quadrilátero Ferrífero region (2059-2041 Ma in the eastern portion of the study area. This evidence, together with chemical and isotopic data from other mafic and felsic plutons coeval with the Glória quartz-monzodiorite, indicate a tectonic and magmatic migration within the Mineiro belt from west to east.O Quartzo Monzodiorito Glória é um corpo plutônicomáfico associado à evolução Paleoproterozóica do Cinturão Mineiro.

    Genotypes x environment (G x E) interaction consists of different behavior of genotypes cultivated in different environments. This interaction occurs due to the performance variation of each genotype in different environments. To reduce the effect of the interaction in soybean crops, some studies have been reported in the literature to study their adaptability and stability. However, these studies are still scarce in Minas Gerais State. Thus, the aim of this study was to verify the adaptability and stability of soybean cultivars and identify the cultivars that contribute least to the G x E interaction in Minas Gerais. Six soybean cultivars were evaluated in 9 different environments. The plots were composed of 4 rows of 5 m with a spacing of 0.5 m between rows, and only the two central rows were harvested. The inoculation with Bradyrhizobium japonicum was performed through sowing furrow. The fertilization followed the recommendations of the Soil Fertility Commission of Minas Gerais. Grain yield was evaluated in kg/ha after conversion to 13% moisture. After individual analysis, the joint analysis was performed by grouping the phenotypic means by the Scott and Knott (1974) test. Wricke's ecovalence methodologies and the Annicchiarico confidence index were applied for the adaptability and stability analysis. The interaction was decomposed into a simple and a complex part. The cultivars BRSMG 820RR and BRSMG 760SRR have wide adaptability and stability. The first one presents a better index of confidence and a small contribution to the interaction.

    Full Text Available O Cerrado é uma das principais regiões de expansão agropecuária do país, entretanto a fragilidade dos seus ecossistemas restringe a capacidade de suporte a muitas das atividades agrícolas e compromete a preservação da sua biodiversidade. O objetivo deste estudo foi definir padrões locais de características edáficas e vegetacionais, em uma sub-bacia em Rio Pardo de Minas (MG, como base para o planejamento local de uso sustentável. Para tal, foram utilizadas técnicas de levantamento fitossociológico e de solos associadas à análise estatística multivariada, dendrograma e análise de componentes principais, de forma a correlacionar distribuição espacial de grupos de espécies e atributos edáficos. Os resultados indicaram a ordenação dos ambientes em dois grupos, em função da natureza dos materiais de origem: arenítico-quartzítico e sedimentos argilo-arenosos e argilosos. A seleção de variáveis pela análise multivariada foi capaz de discriminar os ambientes representados no levantamento fitossociológico. Os padrões identificados pelos agricultores corresponderam, em geral, às variações nos parâmetros florísticos e fitossociológicos e aos atributos edáficos, entre estes a densidade absoluta, a área basal e o índice de diversidade; as frações granulométricas foram determinantes na diferenciação dos ambientes.The Cerrado is one of the main Brazilian expanding regions for agriculture, but the fragility of its ecosystems limits the support capacity for agriculture activities, jeopardizing the preservation of its biodiversity. The objective of this study was to define local patterns of edaphic and vegetation characteristics, of a small watershed in Rio Pardo de Minas municipality (Minas Gerais State, Brazil, as the basis for the sustainable planning for local usage. For such, techniques of phytosociological survey and soils were applied and associated to multivariate statistical procedures, dendrogram and PCA

    A retrospective study based on observation with the objective of identifying and characterizing the different risk areas for rabies transmission by dogs took place in Minas Gerais State, Brazil, from 1991 to 1999. Indicators confirmed occurrences of canine and feline rabies, notification of human rabies, and administration of appropriate vaccination. The Minas Gerais State Health System is divided into 25 Regional Health Centers, which are linked to the State Health Department (SES-MG). These Health Centers were utilized in the study. The results of 2,845 records of laboratory diagnosis for canine, feline, and human rabies were analyzed. Consolidated SES-MG reports from 1997 to 1999 for rabies vaccination and notification records for cases of human rabies from the National Health Foundation (FUNASA) were also used. In order to verify the local reality, a semi-structured interview with each regional program director was conducted. Minas Gerais presents four different risk modalities, classified as zero, low, medium, and high.

Seed germination and seedling emergence of Anadenanthera colubrina were studied to examine the reproductive efficiency of this species, typical of Cerrado biome. The fruits were collected in ‘Vale do Rio Araguari’, in MG state. The water content at 105 °C, the germination in controlled laboratory conditions and seedling emergence in semi-open greenhouse were analyzed. The seeds had low water content between 6.7 to 10.7%. The germinating ability and the emergence percentage were high for almost all studied individuals, being registered 68 for seeds of individual number 2 and 85 - 94% for the others; 38% (individual number 2 and 78 - 91% (for the others, respectively. The speed of the processes was high, with the end of germination within 12.8 days and emergence within 18.8 days. The processes were heterogeneous, with values of coefficient of variation of the germination or emergence time above 28.5%; asynchronous, with values of uncertainty above 1.5 bits and synchrony below 0.3812. The seeds of this species were efficient in both processes and the heterogeneity and asynchrony may indicate the effects of environmental fluctuations during the seed formation, besides the genetic variability, intrinsic to each individual of the population. The speed and the high potential of seed germination of this species may also facilitate the programs of reforestation with the production of large numbers of seedlings in short time.

Asistir al centro de salud, no tener una primera consulta con un nefrólogo pagado por el SUS y contar con la opción de elección para el tratamiento de la enfermedad renal son factores relacionados con la iniciación prevista de la diálisis. La diálisis no planificada es común en la ciudad de Belo Horizonte y se produce independientemente del momento en el que se deriva al paciente al nefrólogo.The objective was to analyze factors associated with planned initiation of dialysis in diabetic patients in the city of Belo Horizonte, Minas Gerais State, Brazil. This was a cross-sectional study of 250 diabetic patients who began dialysis between January 2006 and December 2007. Initiating dialysis with an arteriovenous fistula or in peritoneal dialysis was classified as planned initiation. The study targeted socio-demographic, clinical, and health services use variables using a semi-structured interview. Multivariate analysis used Poisson regression. Seventy per cent of the patients began dialysis on an unplanned basis, and 67% of those consulted had been referred to a nephrologist more than four months previously. Attending a health center, not having the first nephrology appointment paid for by the Brazilian Unified National Health System, and having a choice of treatment for the kidney disease were associated with planned initiation of dialysis. Unplanned initiation of dialysis is common in the city of Belo Horizonte and occurs regardless of the time since referral to the nephrologist.

    The Quadrilatero Ferrifero with an area of about 7000 km 2 is located south of Belo Horizonte in Minas Gerais, Brazil. Precambrian metaconglomerates (Proterozoic) of the Moeda Formation and Maquine Group are believed to be favorable host rocks for uranium deposits. Some areas are now being studied or have work planned for next year. Drilling succeeded in detecting at least three channels in different areas with ore-grade uranium-bearing oligomictic conglomerates. Reserve calculations require additional detailed work in those areas. Some models indicate that the sediments came from the Sao Francisco Craton, but paleocurrent directions in the Gandarela Syncline, as well as at Jacobina, indicate that the detritus came from the east, at least at these sites. This means that other cratonic areas must exist to the east of these outcrops. The Quadrilatero Ferrifero is mostly included between lat 19 0 45' and 20 0 30'S and long 43 0 22'30'' and 44 0 7'30'' W and lies near Belo Horizonte, Minas Gerais State, Brazil

    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.

    The Pocos de Caldas natural analogue project is an internationally funded project hosted by Brazil; the contributary organizations are SKB (Sweden), NAGRA (Switzerland), DOE (United Kingdom) and the DOE (United States). The Project is a multidisciplinary study of two mineralized areas within an alkaline igneous caldera complex located near the town of Pocos de Caldas in the state of Minas Gerais. One area, the Osamu Utsumi mine, is characterized by redox deposits of secondary remobilized pitchblende, and the other area, Morro do Ferro, comprises a highly weathered deposit of thorium and REE with subordinate uranium. The project, scheduled for three years (1986-1989), is now entering its third and final year. The pilot and feasibility studies, which characterized the first year, helped to establish the major drilling programme and the sampling protocols for both rock and groundwater studies which constituted the major part of the second year. The latest status of the investigations are briefly reported

    Full Text Available This paper was aimed at conducting a bibliographical research on Environmental Impact Assessment (EIA, Strategic Environmental Assessment (SEA and their relation to the Ecological Economic Zoning (EEZ in the state of Minas Gerais. It is believed that the EIA is subject to failures as it does not take into account larger impacts upon space, time, cumulative and synergistic effects, whereas reflecting a reductionist point of view of the undertaking to the detriment of a broader, systemic, holistic perspective. With a view to compensate for such failure, the SEA is seen as an appropriate tool for the evaluation of political impacts, plans and programs which, conversely, guides the implementation of projects in an more integrated manner. Therefore, two EIAs can be used as reference; one refers to a rural electrification program in the state of Minas Gerais and the other approaches the integration planning of water sources in the metropolitan area of the state of São Paulo. While planning the Ecological Economic Zoning of the state, Minas Gerais takes a decisive step forward the reduction of conflicts related with multiple interests of economic development, providing and forming the basis for the essential balance among profit, preservation and environmental conservation, social justice, respect and cultural diversity, political and institutional maturation, ethic and plurality, which splash the sustainability colors on the canvas of the future.

    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.

    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.

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

    Full Text Available Vulnerability to climate change is a complex and dynamic phenomenon involving both social and physical/environmental aspects. It is presented as a method for the quantification of the vulnerability of all municipalities of Minas Gerais, a state in southeastern Brazil. It is based on the aggregation of different kinds of environmental, climatic, social, institutional, and epidemiological variables, to form a composite index. This was named “Index of Human Vulnerability” and was calculated using a software (SisVuClima® specifically developed for this purpose. Social, environmental, and health data were combined with the climatic scenarios RCP 4.5 and 8.5, downscaled from ETA-HadGEM2-ES for each municipality. The Index of Human Vulnerability associated with the RCP 8.5 has shown a higher vulnerability for municipalities in the southern and eastern parts of the state of Minas Gerais.

    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.

    The Caldas Ore Treatment Unit (UTM-Caldas), located at the municipality of Caldas (Minas Gerais-Brazil), was a site for the exploration and treatment of uranium between 1982 and 1995. The area is located in the Alcalino Complex of Poços de Caldas, a geologically peculiar region, composed of alkaline igneous rocks with exotic minerals, some rich in rare earth elements (REE). The UTM-Caldas uranium deposit was defined as a U, Th, Zr, Mo and REE mineralization. The objective of the present study was to evaluate the distribution of REEs in river sediments adjacent to UTM-Caldas and to verify if effluents from the mine are interfering in the concentration of REEs in these sediments. To develop the research, five samples were collected in 2011, including sediments from the Soberbo river, the waste dam and the tank of radio precipitation. The samples were prepared in the Sedimentology Laboratory of the Center for the Development of Nuclear Technology (CDTN), where the rocks and tailings were crushed, ground and pulverized while the sediments were sieved and an aliquot of the silt-clay fraction was separated for analysis at the CDTN. The analytical method employed was Neutron Activation Analysis (ANA), method k{sup 0}. The samples were irradiated in the TRIGA MARK I IPR-R1 research reactor, and the REEs identified by gamma-spectrometry in the Neutron Activation Laboratory (LAN-CDTN). The results showed a distribution model of the REEs in the study area, which may be useful in evaluating of the environmental impacts of effluents from UTM-Caldas, now in the process of decommissioning.

    2012-12-01

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

    Full Text Available Gerai Pond is one of the last natural wetlands along the Danube, being connected to natural flooding regime of the Danube and is situated at the confluence of the Danube River, between Gârcov and Islaz localities, in Olt County. Aquatic vegetation characteristic is a favorable habitat for two species of conservation concern that nest along the Danube: red duck and pygmy cormorant. During 1961-1970, Gerai Pond has changed radically due to impoundment and draining under the program of drainage and flood meadow regulate of the Danube. These works of land reclamation for decreasing surface lakes and wetlands and water stagnation period, had reduced the breeding areas of the two species mentioned above. Ecological reconstruction of Gerai Pond project was conducted by Technical University of Civil Engineering of Bucharest in collaboration with E.P.A. Olt and W.W.F.-Romania. The project was based on a hydrological study (which included a component related to flooding for the area analyzed, study in which were highlighted the areas which have water access to and from the Pond, surfaces and volumes of water corresponding to different rates, the optimal level of water for restoration of the nesting area. Based on this study were identified the areas of artificial feed-water discharge to and from the Danube. This paper presents the possible solutions for ecological reconstruction of Gerai Pond, identified in the project.

    This study aimed to verify the performance of blood transfusion committees in transfusion services linked to the public blood bank network of the state of Minas Gerais. A cross-sectional observational study was conducted between 2007 and 2008 using questionnaires and proficiency tests to evaluate the reporting and investigation of transfusion reactions comparing transfusion services with and without transfusion committees in the public transfusion services of the state of Minas Gerais. Nineteen of Hemominas own transfusion services and 207 that contracted the services of the foundation located in 178 municipalities were visited between 2007 and 2008. Established transfusion committees were present in 63.4% of the services visited. Transfusion incidents were reported by 53 (36.8%) transfusion services with transfusion committees and by eight (9.6%) without transfusion committees (p < 0.001) with 543 (97.5%) and 14 (2.5%) notifications, respectively. Of the reported transfusion incidents, 40 (75.5%) transfusion services with transfusion committees and only two (25%) of those without transfusion committees investigated the causes. The incidence of notification and investigation of the causes of transfusion reactions was higher in transfusion services where a transfusion committee was present. Despite these results, the performance of these committees was found to be incipient and a better organization and more effective operation are required.

    Full Text Available Dentre as diversas abordagens teóricas sobre os determinantes da violência urbana, destaca-se a desorganização social, que vincula a incidência criminal a processos de enfraquecimento de mecanismos de controle social. De acordo com esta perspectiva, intensas correntes imigratórias e a aglomeração de grandes massas populacionais em centros urbanos favorecem, potencialmente, a incidência criminal. Este estudo explora a relação entre as taxas de criminalidade violenta e as taxas de imigração, urbanização e tamanho populacional nos municípios mineiros no final da década de 1990, visando confrontar as idéias postuladas pela abordagem da desorganização social com a realidade mineira. Migration, social disorganization and urban violence in Minas Gerais Abstract Among the various theoretical interpretations of urban crime incidence the social disorganization approach deserves attention. This perspective associates crime to weakening social control mechanisms, suggesting that intense migratory flows and the agglomeration of large populations in urban areas potentially favor crime incidence. This study explores the relationship between violent crime rates and immigration, urbanization and total population rates among the municipalities of Minas Gerais State in the 1990s, in order to test the ideas postulated by the social disorganization perspective in Minas Gerais State.

    Full Text Available Aim: This study assessed the water quality from the springs and river mouths of the fifth-order tributaries which compose the reservoir of Marechal Mascarenhas de Morais HPS in the middle Rio Grande watershed, Minas Gerais, Brazil. Methods: It has been studied 14 tributaries distributed in the reservoir, two points for tributary - spring and river mouth. Eighteen limnological variables added to the Rapid Assessment Protocol and Trophic Level Index were evaluated. The benthic macroinvertebrates had been collected by the use of a granulometric sieve and a Petersen-type sampler. Results: The cluster analysis of limnological data revealed the existence of two tributary groups. Group I consisted of eutrophic tributaries degraded by human activities, while group II exhibited good water quality and well-preserved environments. Group I was divided into two subgroups, Ia tributaries were characterized by being altered by human activities, while the Ib subgroup was composed of highly impacted tributaries. By ordering the PCA, it can be observed spatial segregation of groups, where the most polluted tributaries were separated from those which are better preserved. A total of 8,987 individuals belonging to 36 families of macroinvertebrates were identified. The family Chironomidae was the most abundant. There was no significant difference in total abundance and the richness of macroinvertebrates taxa inhabiting springs, by those who inhabiting the river mouths. Conclusions: It was noticed that most of the tributaries which supply and composes the reservoir are already degraded and have low quality water. It is observed that the human presence drastically affected water quality and faunal composition of tributaries. Thus, it is necessary a complementary study of the tributaries in working with issues related to reservoirs, as these components have direct influence on the water quality and composition of these lentic environments.Objetivos: O trabalho avaliou

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

    Full Text Available The Brazilian Law stipulates that water is a limited natural resource doted of economic value, thus it is necessary to develop mechanisms for its adequate management. Actions that encourage the farmers to apply soil conservation practices with the purpose of increase water yield from springs and to promote improvement of its quality, reducing production of sediment transportation, is being encouraged by governments, even with financial compensation for owners. From these assertions, this study aims to quantify the benefits of the conservation actions of the management units and to characterize a Water Yield Indicator (WYI to support sustainable actions in the watershed of Alto Rio Grande region, in the state of Minas Gerais (MG. To assess the impact of actions it were identified four scenarios of land use and occupation of the watershed from Marcela stream which is located in Alto Rio Grande Region. After analyzing the results, it can be stated that the scenarios simulation has demonstrated important changes in water yield and that the definition of the Water Yield Index from the junction of the erosion potential with the water storage potential, has proved effective, as it integrate quantity and quality of water.A legislação brasileira estabelece que a água é um recurso natural limitado e dotado de valor econômico; logo, há necessidade de se criar mecanismos para sua adequada gestão. Medidas que estimulam os produtores rurais a adotarem práticas conservacionistas, visando a maior produção de água, melhoria de sua qualidade e redução da produção de sedimentos, vêm sendo estimuladas pelos governos, utilizando para isso até mesmo uma compensação financeira.

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

    Full Text Available The occurrence of Aviadenovirus (FAdV was investigated in chickens from the poultry industry of Minas Gerais state, Brazil. The investigation was conducted due to the scarcity of recent data in the country and its description in neighboring countries. For this purpose, livers were collected from layer chicks (n=25, older layers (n=25, broilers (n=300, and livers (n=25 and stool (n=25 samples from broiler breeders, representing the major poultry regions of the state. FAdV DNA was demonstrated using a previously described PCR protocol for amplifying part of the hexon gene encoding sequence. FAdV was found in layer chicks (36%, widespread (100% in older layers, and with regional differences in broilers (24-86%. Although all broiler breeder stools were negative, FAdV DNA was detected in livers (16%, 4/25 of stool-negative birds. In order to obtain additional information on the circulation of the infection, livers of subsistence chickens collected from one poultry intensive region, were evaluated (n = 12, with FAdV being detected in all samples. FAdV was found in young and old layers, broilers, broiler breeders and free-range chickens, and results suggest the circulation of FAdV among different types of chickens. The detection in older layer chickens may indicate an extended risk of horizontal transmission in regions of Minas Gerais with mixed activity of egg and meat type chickens and poor biosecurity strategies. The infection in breeders may indicate vertical transmission and the continuous production of infected progenies. The hexon-gene-targeted PCR amplicon sequences aligned with FAdV of species D of Aviadenovirus. Results indicate the necessity for biosecurity, especially for breeders, separating flocks according to origin, age and health status, which will be an advantage regarding any pathogen.

    Prenatal care coverage is still not universal or adequately provided in many low and middle income countries. One of the main barriers regards the presence of socioeconomic inequalities in prenatal care utilization. In Brazil, prenatal care is supplied for the entire population at the community level as part of the Family Health Strategy (FHS), which is the main source of primary care provided by the public health system. Brazil has some of the greatest income inequalities in the world, and little research has been conducted to investigate prenatal care utilization of FHS across socioeconomic groups. This paper addresses this gap investigating the socioeconomic and regional differences in the utilization of prenatal care supplied by the FHS in the state of Minas Gerais, Brazil. Data comes from a probabilistic household survey carried out in 2012 representative of the population living in urban areas in the state of Minas Gerais. The sample size comprises 1,420 women aged between 13 and 45 years old who had completed a pregnancy with a live born in the last five years prior to the survey. The outcome variables are received prenatal care, number of antenatal visits, late prenatal care, antenatal tests, tetanus immunization and low birthweight. A descriptive analysis and logistic models were estimated for the outcome variables. The coverage of prenatal care is almost universal in catchment urban areas of FHT of Minas Gerais state including both antenatal visits and diagnostic procedures. Due to this high level of coverage, socioeconomic inequalities were not observed. FHS supplied care for around 80% of the women without private insurance and 90% for women belonging to lower socioeconomic classes. Women belonging to lower socioeconomic classes were at least five times more likely to receive antenatal visits and any of the antenatal tests by the FHS compared to those belonging to the highest classes. Moreover, FHS was effective in reducing low birthweight. Women who

    Full Text Available ABSTRACT Objective: Study the prevalence of iron depletion and iron-deficiency anemia and their associated factors in preschool children. Methods: Cross-sectional study with five-year old preschool children from a birth cohort of the city of Diamantina, Minas Gerais state, Brazil. Socioeconomic, demographic, and dietary characteristics were obtained through a questionnaire administered to each child mother or guardian. Iron depletion (normal hemoglobin and low serum ferritin levels and iron-deficiency anemia (hemoglobin level than 11g/dL were detected after collecting 5mL of venous blood of preschool children. Poisson regression was used to identify the factors associated with iron depletion and iron-deficiency anemia. Results: A total of 228 preschool were evaluated, corresponding to 97.4% of the children from a cohort study followed-up up to the end of their first year of life. Iron depletion and iron-deficiency anemia were detected, respectively, in 15.9% and 18.9% of the preschool children evaluated. Iron depletion was not associated with any variable studied, while low maternal education level was associated with iron-deficiency anemia (PR=1.83; P=0.03. Conclusion: Iron-deficiency anemia is considered as a mild public health problem among 5-year old children in the city of Diamantina, Minas Gerais. Higher maternal education level was a protective factor against this deficiency, and therefore it is as an important marker for the occurrence of iron-deficiency anemia in the population studied.

    soil properties provides the theoretical basis for a sustainable planning of natural resources. This study evaluated the alteration of chemical and physical soil characteristics in a Haplustox in the Zona da Mata region of the State of Minas Gerais (Brazil, under different crop systems. The systems evaluated were orange orchards, sugar-cane plantation, pasture and forest, as control. Orange orchards and pasture had been established more than 20 years before, both in succession to sugar-cane, previously grown for over a century. The sugar cane is a reminiscent of crop cultivated for more than 120 years. Soil was sampled in pits at depths of 0.0-0.2 and 0.2-0.4 m. The following chemical properties were evaluated: soil organic matter (MOS; pH in H2O, P, Ca2+, Mg2+, K, Al3+, H + Al, SB, CTC (t, and V, and the physical properties: texture, soil density, particle density, porosity, water retention curve, soil penetration resistance, and aggregate stability, as well as the ratio field capacity/soil total porosity. In the data evaluation, the crop systems represented treatments in a completely random design, and analysis of variance was performed for each depth separately. In the crop systems orange and sugar cane the chemical properties were improved, raising the nutrient levels and reducing the exchangeable Al3+, level but SOM was reduced and intermediate levels of physical degradation were observed. In the pasture system, low fertility and a dystrophic character were Stated, reduced SOM and high physical degradation, indicated by increased soil density and soil penetration resistance, and by lower porosity and aggregate stability.

    There are numerous applications given to clays including oil and water adsorbent, ceramic, whitening of beverages, porcelain, waste treatment, organic carrier molecules in cosmetics and pharmaceuticals, support for catalysts. In the pharmaceutical industry, the clays are used as excipients, diluents, desiccants, emulsifiers, to mask undesirable flavors, isotonic agent such as charger and delivery of active substances. These characteristics have contributed to the expansion of the search for applications of clay minerals in the cosmetic industry. The aim of this study was to determine the elemental composition of clays from Campos Gerais, Minas Gerais, with a view to their applicability in the production of cosmetics. The elements As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th,U, Yb and Zn were determined by neutron activation analysis and radionuclide activity concentration of 226 Ra, 228 Ra, 210 Pb and 40 K were determined by gamma spectrometry. It was verified that the activity concentration of radionuclides was in the same concentration as the global average, indicating that these samples do not present a risk of increased radiation exposure. The concentration of most elements determined is less than or equal to the overall mean concentrations, indicated by the values of Continental Upper Crust. (author)

    Full Text Available La capitanía de Minas Gerais presenta una serie de peculiaridades en el contexto de la historia de la América portuguesa. Hasta 1694 fue un territorio vagamente conocido como parte de las zonas despobladas y agrestes de la villa de Sao Pablo; una región de colonización antigua y con una población ya bien sedimentada hacia fmes del siglo XVII. Minas, que había sido recorrida por paulistas en busca de plata y de indios, en la década del 70, fue nuevamente frecuentada por habitantes de Sao Pablo que llegaban empeñados en el descubrimiento de esmeraldas. Éstos, comandados por Fernáo Dias Pais, establecieron un sistema de puestos de víveres que, posteriormente, hizo posibles otras entradas. No se descubrieron esmeraldas, pero, entre 1694 y 1698, se encontró oro de aluvión en varios puntos de la región central del actual estado de Minas Gerais, donde hoy se sitúan las ciudades de Ouro Preto, Mariana y Sabará, en las nacientes del río Doce.

Nineteen soils were collected for this purpose in the Triângulo Mineiro region, Minas Gerais State, Brazil, developed from different parent materials and different weathering degrees. Due to the greater occurrence, a larger number of samples of the Bauru Group was collected, comprising all the geological formations found in the region. The total K content in soil and the sand, silt, and clay fractions were determined after the digestion of the soil samples by HF, HNO3 and H2SO4. To quantify the contribution of each mineral species to the total K content, Na-saturated clay samples were submitted by a sequential and selective mineral extraction procedure, following the order: amorphous Al and Fe oxides; crystalline Fe oxides; kaolinite and gibbsite; mica and other 2:1 minerals and; feldspar and resistant minerals. The clay mineralogy composition reflects the high weathering and leaching degree in soils of the Triângulo Mineiro, with low contents of amorphous minerals, a predominant proportion of kaolinite and the presence of other secondary resistant minerals. In spite of this mineral composition, the clay fraction presented the highest total K content, mainly in the most weathered soils. Due to the high proportion of kaolinite in the clay fraction, this mineral was an important source of non-exchangeable K forms. On the other hand, the contribution of amorphous Fe and Al oxides and crystalline Fe oxides to the total K content of the clay fraction was negligible. In general, easily weathered primary minerals (mica and feldspar contributed largely to the total K of the clay fraction, principally to the youngest soils developed from the Uberaba (sandstone and Serra Geral (basalt Formations, and the Araxá Group (migmatite/micaschist.

    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.

    The Brazilian Sanitary Vigilance Agency is the regulatory authority for radiation protection and quality control of all practices with X-rays for diagnostic purpose. In 1998, the technical regulation 'Guidelines for Radiation Protection in Medical and Dental Radiodiagnostic' was issued by the government that reflected the most updated policy recommended by the International Basic Safety Standards for Protection against Ionizing Radiation. To accomplish the objective of improving radiation protection conditions in the state of Minas Gerais, the Development Centre of Nuclear Technology (CDTN) and the Superintendence of Sanitary Vigilance (SVS) signed a formal cooperation agreement that included: an accreditation process for radiation protection professionals, a follow-up program of the services provided by those professionals, technical support from CDTN for audits carried out by SVS and training of SVS inspectors. Actions to improve and assure metrological reliability of the radiation measurements and special attention to mammography services were done. This paper provides details and results of the radiation protection framework for X-ray radiodiagnostic services in Minas Gerais; the success of the adopted model suggests that it can be used as a basic model to other regions.

    Dengue, caused by any of the four types of Dengue virus (DENV) is the most important arbovirus in the world. In this study we performed a molecular surveillance of dengue during the greatest dengue outbreak that took place in Divinópolis, Minas Gerais state, Southeast Brazil, in 2013. Samples from 100 patients with clinical symptoms of dengue were studied and 26 were positive. The capsid/premembrane (CprM) and envelope gene sequences of some samples were amplified and sequenced. Molecular analyses demonstrated that two DENV-1 lineages, belonging to genotype V were introduced and co-circulated in Divinópolis. When compared to each other, those lineages presented high genetic diversity and showed unique amino acids substitutions in the envelope protein, including in domains I, II, and III. DENV-4 strains from Divinópolis clustered within genotype IIb and the most recent common ancestor was probably introduced into the city three years before the 2013 epidemic. Here we demonstrated for the first time the circulation of DENV-4 and the co-circulation of two DENV-1 lineages in Midwest region of Minas Gerais, Brazil. Moreover our analysis indicated the introduction of five DENV-1 lineages, genotype V into Brazil, in different times. J. Med.

    Parasitic infection is recognized worldwide as a limiting factor in the production of goats, and various control methods are used to reduce economic losses, often without considering the epidemiology of the parasites. This has led to the development of highly tolerant parasite populations and the presence of chemical residues in the beef and milk. The objective of this study was to determine the level of knowledge of goat farmers about parasitic diseases and to correlate this with the epidemiology of endoparasites and parasite control practices in goat farms in the state of Minas Gerais, Brazil. The analysis was based on a questionnaire applied by trained veterinarians. The sample was homogeneous throughout the state, covering 18.4% (157/853) of municipalities. Eighty-four dairy goat farms in 81 municipalities and 200 properties with beef goats in 76 municipalities were evaluated. The herd size per goat farm ranged from 4 to 57 (average 24) for beef herds and from 2 to 308 (average 63) for dairy farms. The majority of the beef herd production was extensive and semi-extensive (98.5%), while the dairy herds were maintained under intensive farming (98.8%). The mixed production of goats and sheep was reported by 36.5% of beef goat farmers and by 20.2% of dairy goat farmers. Among the beef goats farms on which the technological level was determined, 2.0% were categorized as having high technological level, 34.5% as medium, and 63.5% as low. Of the 84 dairy farms, 30% operated at a high, 47% at a medium, and 23% at a low technological level. The adoption of practices to reduce parasitism, such as the quarantine of animals, treatment of newly arrived animals, regular cleaning of the floor, and technical assistance, was significantly higher on dairy farms than on beef farms. Although 85.7% of dairy farmers and 83% of beef farmers medicate their animals, the treatments were performed without technical criteria, and deworming intervals ranged from 30 to 120 days or more.

    Full Text Available The mining areas and artisanal mining represent a complex problem for public management in Brazil, since it is notice issues related to environment, social and economic vulnerability. The priority given by the State to mineral cooperatives in the Federal Constitution of 1988 in the authorization or concession for research and mining of resources and mineral reserves marks a process of the State attempt to regularize, standardize and encourage the regularization of illegal mining in small scale, where the mining is presented. So, the motivation for this study started in order to uncover the main challenges faced by cooperatives of mineral branch to operate mining activities in Minas Gerais. The- refore, we sought through case study to understand the operation of two organizations in this sector, the Uniquartz in Corinto and Microminas in Córrego Fundo. In terms of methodological approaches, our study was characterized as theoretical-empirical as exploratory-descriptive, with a qualitative approach and multi-case study method. The results of the study point the operating challenges of the two cooperatives permeate by institutional policy issues, access to credit, technical-operational and sociocultural. These issues impact the operation of these organizations, which in some measures end up working punctually to solve a structural problem.

    Full Text Available Epidemiological and health aspects of sheep husbandry were assessed on 213 sheep flocks in 142 municipalities from the state of Minas Gerais, southeastern Brazil. An updated questionnaire was filled out for each flock, requesting data on the farm, the flock and the farmer by the veterinarians of the State Government Agency for Animal Health (Instituto Mineiro de Agropecuária. Thirteen important variables were selected and scored to determine the technological level of the 117 farms; 0.9% of them was classified as high technological level, 45.3% as medium technological level and 53.0% as low technological level. Lamb production was the main objective of the farms and the main features were low-frequencies of individual identification of animals (16.9%, technical assistance (31.9%, use of quarantine for newly acquired animals (0.9% the separation of animals by age group (3.7% and requeste the sanitary certificate at purchasing of animals (11.7%. The main health problems reported were abortion (23.9%, keratoconjunctivitis (17.9%, contagious ecthyma (13.6%, pneumonia (10.3%, diarrhea (9.3% and caseous lymphadenitis (6.1%. Information of the epidemiological situation and the mainly health measures used in the sheep farms are important to improve the productivity and quality of the lamb.

    There is some evidence that dogs can be naturally infected by Paracoccidioides brasiliensis in endemic areas of paracoccidioidomycosis. In order to evaluate canine infection with this fungus, a survey with 149 urban and 126 rural dogs was carried out using ELISA and intradermal tests with the gp43 antigen of P. brasiliensis in Uberaba, Minas Gerais state of Brazil. Forty-one out of 149 urban dogs were euthanatized and had their lungs, liver and spleen removed. One slice from each viscera was processed for histopathological examination and the remaining was homogenized and then cultivated on mycobiotic agar at room temperature and Fava-Netto medium at 35 degrees C and observed for 12 weeks. Of urban dogs, 75 (50.3%) were small adult females, 56 (36%) were strays, while 93 (64%) had been donated to the municipal zoonosis control center. Nine (6.2%) had a positive intradermal test without statistical differences regarding gender, race, nutritional status or origin. No colonies with microscopic or morphology appearances resembling P. brasiliensis were isolated, nor granulomatous process or fungal structures were observed from histopathological examination. Eighty (53.6%) of the urban dogs presented seroreactivity, without statistical differences regarding gender, race, nutritional state, origin, or positive intradermal test. Of 126 rural dogs, 102 (80.5%) presented antibodies against gp43 antigen, and this was statistically significant in relation to the reactivity detected in urban dogs (P = 0.0001). Thus, dogs are commonly infected with P. brasiliensis, but they probably present natural resistance to develop paracoccidioidomycosis.

The grain yield data of the advanced comparative trials of both cultivars and lines of irrigated rice, conducted in several regions of the State of Minas Gerais over the period of 1974/75 to 1995/1996 were utilized. The average genetical gain obtained was of 33 kg/ha/year (0.98%, being highly significant (P< 0.01. The 22 year period was subdivided into two phases: at the first phase (1974/75 to 1979/80, a gain of 203 kg/ha/year (6.06% was noticed, which was highly significant, and the second phase (1980/81 to 1995/96 presented a gain of 15 kg/ha/year (0.25% being non significant. The high gain of the first phase is ascribed to the replacement of traditional high size and poor yielding potential for breeding materials such as Inca, BG 90-2 and MG 2. In the second phase of the program, increased attention was given to obtain materials more resistant to diseases and with better grain quality and non-significant gains for yield were obtained.
