    Mining is one of the leading sectors of the Brazilian economy and as any other anthropogenic activity it generates residues that impact the environment directly. The Osamu Utsumi Mine, which belongs to the Nuclear Industries of Brazil (INB), operated from 1982 to 1995 with the activities of mining and metallurgical treatment of the uranium ore. Since then the INB has as a main environmental problem, the generation of acid mine drainage from wastes having its pH around 3. The chemical treatment of this acid water incurs an extremely high cost and generates a precipitate that is rich in some metals, including uranium. This precipitate has been disposed of in the mine opening and has caused an overload of chemical pollutants and radioactive elements in a place that was not planned to receive this volume of residues and does not meet the necessary condition for the construction of a repository. The content of uranium in the precipitate is approximately 0.25% - similar to the content of the metal found in the ore in the Caetite Mine (BA) - around 0.29%. The recovery of this uranium from the precipitate would generate a total of 150 tons of U 3 O 8 . In the present study an alkaline leaching process was carried out aiming at recovering the uranium from sludge samples disposed of for over 20 years. Sodium carbonate and bicarbonate were used as the leaching agents. The experiments were carried out by varying the concentrations of the leaching agents, extraction time and the solid percentage. The other parameters such as temperature, particle size and agitation were kept constant. The results showed that the recovery of the uranium can reach 100% in 24 hours. The uranium concentration in the solutions is around 250 mg.L -1 when using 10% of solids. Preliminary results showed that the recovery of uranium from the sludge would be a feasible practice. The conversion of an environmental liability into a valuable product is one of the most important objectives of this work

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

    The determination of the volumes of the sterile piles generated in the uranium mining and their respective characterization is of extreme importance for the management of mining wastes and future decommissioning actions of a nuclear facility. With the development of information technology, it becomes possible to simulate different scenarios in a computational environment, being able to store, represent and process data from existing information. In the industrial mining context, the sterile is represented with rocky materials of different granulometries and with ore content below the cut content determined by the industrial process. In this sense, the present work has the objective of calculating the volume of the sterile stacks of the Osamu Utsumi uranium mine of INB - Nuclear Industries of Brazil / Caldas. The MOU was officially inaugurated in 1977 and operated until 1995, where 1,200 tons of U{sub 2}O{sub 3} were produced generating about 94.5 x 106 tons of sterile material containing low levels of radioactive material and pyrite. The methodology for the development of this work initially involves integration approaches between the Geographic Information System (GIS) and terrain modeling for the sterile piles called BF4 and BF8. The results obtained were compared with the existing literature, translating the importance of GIS as a tool in the management of wastes.

    From 1982 to 1995, the Brazilian Nuclear Industries (INB) extracted and processed uranium from the Osamu Utsumi mine, located in Caldas (Minas Gerais/Brazil). After the operations were suspended in the mine, INB was convened to meet national regulatory requirements for decommissioning the mine. Several studies have since been initiated in order to support a safe and responsible closure of the mine. In this context, this work aims to establish and validate a non-destructive methodology for quantitative simultaneous determination of major and minor constituents in soil and sediments from Osamu Utsumi uranium mine by wavelength dispersive X-ray fluorescence spectrometry (WDXRF). The method was validated in accordance to the criteria established by INMETRO (Brazilian's National Institute of Metrology, Quality and Technology). The precision and accuracy achieved are statistically comparable to the National Institute of Standards and Technology's standard reference material, SRM 2709a. The results showed significantly higher amounts of rare-earth elements and uranium in sediment samples, most likely because of the leaching process occurring in the pit's surroundings. This process is promoted by the acid mine drainage (AMD) that solubilized the elements present in the tailings throughout the mine's area. The solubilized elements end up accumulating in the pit water and further depositing up in the sediment. (author)

    The Osamu Utsumi Mine - MOU, belonging to the Brazilian Nuclear Industries - INB, began in 1977 with pickling activities and remained in operation until 1995. During this period, 94 million tons of rocks were removed, which caused the generation of large wasted rock piles. The intense drainage and precipitation in the study region favored the oxidation and leaching of the wasted rock piles, causing the Acid Drainage of Mine - DAM and generating effluents with low pH and high concentrations of fluoride, aluminum, iron, manganese, sulfate, zinc, uranium and Radio, among others. Currently the MOU is in the process of decommissioning and environmental remediation. The understanding of the hydrogeochemical processes and the behavior of the water flow through different aquifers is extremely important so that the actions of environmental remediation and control of the DAM are really effective. In this sense, in this work, geoprocessing and hydrochemical techniques were used to propose a conceptual hydrogeochemical model in the MOU cavity system and wasted rock pile number 4 - BF4. The geoprocessing techniques allowed to characterize and size the area under study and to integrate information on geology and mineralogy with the hydrochemical data. The hydrochemical studies were based on three groundwater sampling campaigns, using the low flow method in 17 monitoring wells, as well as 3 water reservoirs in the study area. In the collected samples were determined: (1) the main cations and anions for groundwater classification using Piper and Stiff diagrams and multivariate statistical methods (cluster and Principal Component Analysis); (2) the major long half radionuclides and {sup 222}Rn to assess radioactivity and imbalance between them; (3) the stable isotopes of {sup 18}O and {sup 2}H to provide information on the underground flows and water source; (4) the Tritium values found in the samples to estimate the age of the groundwater; (V) the sulfur and oxygen isotopes

    The chemical, isotopic and mineralogical alteration which occurred during primary uranium ore deposition at the breccia pipe-hosted Osamu Utsumi mine, Pocos de Caldas, Brazil, was studied as a natural analogue for near-field radionuclide migration. Chemical and isotopic alteration models were combined with finite difference models of the convective cooling of caldera intrusives. Application of the chemical models successfully used to interpret mineralization and alteration at the Osamu Utsumi mine to the hypothetical waste repository shows that even in a worst case scenario (waste emplaced in a permeable host rock with no measures taken to inhibit flow through the repository), the amount of hydrothermal alteration in the hypothetical repository will be about 0.1% of that in the breccia pipe at the Osamu Utsumi mine. Assuming no barriers to uranium mobility, uranium precipitation above the hypothetical repository would be 0.05 ppm (rather than 50 ppm), hydrothermal alteration 0.03 wt.% (rather than 30 wt.%), etc. The analysis indicates that mineralogical alteration is extremely sensitive to thermodynamic data. Prediction of mineralogical alteration (which may be necessary to predict the migration of radionuclides other than uranium, for example) probably cannot be based directly on even very carefully collected laboratory thermodynamic data. Mineralogical complexities of the system, as well as database uncertainties, will require calibration of the thermodynamic framework against mineralogical alteration observed in the laboratory or field by procedures briefly described.

    The Pocos de Caldas project is a wide-ranging natural analogue study focussed on a number of areas of concern in the performance assessment of the disposal of radioactive waste. Part of the work has involved characterising microbial populations and their influence in various processes. Core material and groundwaters have been sampled for microbiological content at various depths form boreholes at the Osamu Utsumi open pit uranium mine and Morro do Ferro Th/REE ore body. Microbes were found in all samples but numbers do not appear to be related to depth. Analyses of groundwaters gave higher numbers than with solid material and demonstrated the presence of sulphur cycle bacteria. These observations have been compared with predictions of a model used in performance assessment to calculate the maximum biomass/microbial activity based on constraints set by available nutrients and energy. The main conclusions of this analysis are: 1. Low microbial activities can be supported by the energy and nutrients supplied by alteration processes at or around the redox front. The maximum annual production of approximately equal to 0.01 - 0.1 g biomass (dry)/m 2 of redox front is in reasonable agreement with observed standing populations. 2. The presence of high concentrations of sulphate reducing bacteria around the redox front indicate a complex sulphur geochemistry which may be predominantly microbially catalysed and could explain the nodular form of pitchblende concretions and the presence of secondary pyrite. 3. There is little trace element mobilisation by organic byproducts and the main role of microbes in this system is to catalyse specific redox reactions. (au)

    The Osamu Utsumi mine and Morro do Ferro study sites lie within the Pocos de Caldas plateau which is roughly circular in outline with a diameter of 35 km and an area of approximately 800 km 2 . Its general altitude lies between 1300 and 1600 m. The plateau is the eroded form of a caldera which initially intruded some 80 million years ago. Geomorphologically, both sites occupy watershed areas adjacent to small streams in the centre of the plateau. The climate of the area has a marked wet season from November to April and is dry the rest of the year. The streams are ephemeral in their upper reaches, tending to dry up in the dry season as they are fed by a declining base flow. In the wet season they exhibit flash floods fed by high-intensity rainfall causing overland flow. The wet season also provides recharge to the groundwater. Natural slopes are steep and the original vegetaion was thin forest cover which is now restricted to the valley bottoms; usable slopes have poor quality grass cover used for cattle grazing. The plateau is a stable feature and its surface has been eroding at an average rate of 12 m per million years over a period of 50 million years. (author) 21 figs., 47 refs

    Geochemical processes involving water-rock interactions have been modelled using groundwater composition, mineralogical data, ion plots and computations of speciation, non-thermodynamic mass balance and thermodynamic mass transfer for two natural analogue sites near Pocos de Caldas, Brazil: the Osamu Utsumi mine and Morro do Ferro. The main rock type is an alkaline igneous complex composed of volcanic and sub-volcanic phonolites that have been hydrothermally altered and highly weathered. This altered rock mass grades from a laterite at the surface to a saprolite and finally to unweathered, hydrothermally altered bedrock at depth. The mine site contains high concentrations of uranium and Morro do Ferro contains high concentrations of thorium and rare-earths. The reaction models can reproduce the water chemistry and mineral occurences and they were validated by predicting the masses of minerals precipitated and the pH of the final water. The model computations can also reproduce the pH and iron concentrations of the water samples during CO 2 degassing and iron(II) oxidation from exposure to air. The results from the geochemical reaction models reveal that the dominant processes are production of CO 2 in the soil zone through aerobic decay of organic matter, dissolution of fluorite, calcite, K-feldspar, albite and manganese oxides, oxidation of pyrite and sphalerite and precipitation of ferric oxides, silica and kaolinite. Recharge waters are undersaturated with respect to barite and discharging waters and deeper groundwaters are saturated to supersaturated with respect to barite, demonstrating a strong equilibrium solubility control. Strontium isotope data demonstrate that sources other than calcium-bearing minerals are required to account for the dissolved strontium in the ground. These may include K-feldspar, smectite-chlorite mixed-layer clays and goyazite. (author) 24 figs., 4 tabs., 18 refs

    The Osamu Utsumi mine and Morro do Ferro study sites lie within the Pocos de Caldas plateau which is roughly circular in outline with a diameter of 35 km and an area of approximately 800 km 2 . Its general altitude lies between 1300 and 1600 m. The plateau is the eroded form of a caldera which was initially intruded some 80 million years ago. Geomorphologically, both sites occupy watershed areas adjacent to small streams in the centre of the plateau. The climate of the area has a market wet season from November to April and is dry the rest of the year. The streams are ephemeral in their upper reaches, tending to dry up in the dry season as they are fed by a declining base flow. In the wet season they exhibit flash flood fed by high-intensity rainfall causing overland flow. The wet season also provides recharge to the groundwater. Natural slopes are steep and the original vegetation was thin forest cover which is now restricted to the valley bottoms; usable slopes have poor quality grass cover used for cattle grazing. The plateau is a stable feature and its surface has been eroding at an average rate of 12 m per million years over a period of 50 million years. The mine geology is dominantly volcanic to subvolcanic phonolites that have been hydrothermally altered. Fracturing of the rock is extensive. Downward diffusion of oxygen in groundwaters during deep weathering has produced a distinct redox zone seen as a colour change from green/grey to brown/yellow. Morro do Ferro has a more weathered version (laterite/clay) of the same geology penetrated by magnetite breccia dykes. Whilst the area surrounding Morro do Ferro remains untouched, that around the mine has been seriously disturbed by mining activity which has penetrated the water-table. The existing mine has modified groundwater flow patterns and disturbed the movement of oxidising and reducing waters. (au) (47 refs.)

  20. Hydrochemical and isotopic study of groundwater impacted by the acid drainage of UrÂnio Mine - Osamu Utsumi, PoÇos de Caldas Plateau (MG), Brazil

    The Osamu Utsumi Mine - MOU, belonging to the Brazilian Nuclear Industries - INB, began in 1977 with pickling activities and remained in operation until 1995. During this period, 94 million tons of rocks were removed, which caused the generation of large wasted rock piles. The intense drainage and precipitation in the study region favored the oxidation and leaching of the wasted rock piles, causing the Acid Drainage of Mine - DAM and generating effluents with low pH and high concentrations of fluoride, aluminum, iron, manganese, sulfate, zinc, uranium and Radio, among others. Currently the MOU is in the process of decommissioning and environmental remediation. The understanding of the hydrogeochemical processes and the behavior of the water flow through different aquifers is extremely important so that the actions of environmental remediation and control of the DAM are really effective. In this sense, in this work, geoprocessing and hydrochemical techniques were used to propose a conceptual hydrogeochemical model in the MOU cavity system and wasted rock pile number 4 - BF4. The geoprocessing techniques allowed to characterize and size the area under study and to integrate information on geology and mineralogy with the hydrochemical data. The hydrochemical studies were based on three groundwater sampling campaigns, using the low flow method in 17 monitoring wells, as well as 3 water reservoirs in the study area. In the collected samples were determined: (1) the main cations and anions for groundwater classification using Piper and Stiff diagrams and multivariate statistical methods (cluster and Principal Component Analysis); (2) the major long half radionuclides and 222 Rn to assess radioactivity and imbalance between them; (3) the stable isotopes of 18 O and 2 H to provide information on the underground flows and water source; (4) the Tritium values found in the samples to estimate the age of the groundwater; (V) the sulfur and oxygen isotopes present in the

    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 A drenagem ácida de mina (DAM é um problema ambiental em escala mundial. Ela é proveniente do processo de oxidação química de materiais da mineração que contenham minerais sulfetados expostos a condições atmosféricas com a mediação de bactérias. As águas ácidas geradas nesses ambientes podem comprometer a qualidade dos recursos hídricos. Para tentar conter essa DAM, métodos de prevenção e remediação têm sido aplicados. As coberturas secas têm sido estudadas como alternativa de prevenção, visto que a remediação tem mostrado-se de custo elevado. O objetivo deste trabalho foi avaliar o uso de coberturas alcalinas para controlar a geração de ácido proveniente do estéril da mineração de urânio, U, por meio de sistemas colunas de lixiviação. Para isso, foram estudados sistemas de coberturas que têm como agentes de neutralização a lama vermelha, o calcário e a cal. Amostras de estéril e de água foram coletadas na mina Osamu Utsumi, em Caldas, MG. Foram realizadas análises químicas e mineralógicas do estéril, da cal, do calcário e da lama vermelha. Para os testes cinéticos, foram montadas sete colunas de lixiviação: C1(estéril; C2 (estéril + cobertura de lama vermelha; C3 (estéril + cobertura de calcário; C4 (estéril + cobertura de cal; COB2 (cobertura de lama vermelha; COB3 (cobertura de calcário; e COB4 (cobertura de cal. As amostras lixiviadas foram monitoradas por 100 dias. Os resultados mostraram que a cal e a lama vermelha têm maior potencial neutralizador. No entanto, esses agentes neutralizantes oferecem o inconveniente de introduzir material solúvel no lixiviado. Dessa forma, considerando os parâmetros avaliados, foi demonstrado que o uso de mistura de lama vermelha com estéril do Bota-fora 4 (BF4 pode ser uma alternativa viável para o controle de geração de DAM associada à reciclagem de resíduos industriais alcalinos.

    Full Text Available Dazai Osamu (1909-1948, a modern Japanese writer, wrote “Run, Melos!” in 1940. The short story is a rework of an Ancient Greek legend of Damon and Pythias from the 4th century B.C., which was introduced to Dazai through Schiller’s version of the legend, “The Hostage”. The legend, based on a true event, represents the perfect friendship and was reworked a number of times by different antique writers. After having been forgotten for a while, it reappeared in the Middle Ages as a fictional story and has gotten many new adaptations from then on. One of them was Schiller’s ballad in 1798, which – alongside an anecdote from Dazai’s own life – represented the basis for Dazai’s story. Even though “Run, Melos!” is not an autobiographical work, Dazai managed to pass his own feelings onto the characters, add some biblical elements, and included a never-before-employed dark twist in the story, thus making his version more realistic than the preceding ones. Despite the distance in time and place between him and the legend, with “Run, Melos!”, Dazai managed to retell a Western literature story, making it a part of the Japanese literature as well, adding motifs and themes influenced by his own life, time, and place.

    Acid mine drainage (AMD) is a process that occurs in many mining that have sulfide ores. With water and oxygen, several metals are oxidized, one example being uranium. At the mine pit of the Osamu Utsumi Mine located at INB - Caldas and in two other boot-wastes (mining waste pile), AMD is present and currently, without a technological solution. The acidic water present in the pit is treated with hydrated lime, generating water for disposal and an alkaline residue called calcium diuranate - DUCA. The DUCA has a concentration of approximately 0.32% U{sub 3}O{sub 8}, which makes interesting the development of a process for extracting that metal. One of the processes that can be used is leaching. For this study, it was decided to evaluate the alkaline leaching to extract the uranium present in the residue. It is necessary to optimize operational parameters for the process: percentage of solids, concentration of leaching agent in solution, temperature and reaction time. With these parameters, it is possible to improve the leaching so that the largest amount of uranium is extracted from the sample, to help solve the environmental impact caused by the wastewater from the treatment of acid waters and, in addition, to give an economical destination for this metal that is contained in the deposited DUCA.

    Jesus, Honerio Coutinho de

    1996-04-01

    This work, which was realized within the Natural Analogue Project Pocos de Caldas, had as its main objective the study of the colloidal behavior of U, Th, REE and some other elements of geochemical interest, in surface and groundwaters from the Osamu Utsumi mine and the Morro do ferro in Pocos de Caldas, Minas Gerais. Ultrafiltration techniques with flat membranes of different molecular mass exclusion limits (100 K, 10 K e 1K daltons) were used for this purpose. In addition, suspended matter (>0,45 μm), retained during pre-filtering of the waters, was analysed mineralogically and chemically (U, Th, REE, isotopic composition of U and Th, etc). Studies of the chemical composition of colloidal particles (<0,45 μm) and their size distributions were performed using ESCA and SEM, respectively. In addition, speciation studies by means of the MINEQL computation program were made to obtain information about the principal complexed species of relevant elements and the formation of solid phases. All the above mentioned investigations were aimed at better understanding of the migration and sorption behavior of U, Th and REE in both environments. The data obtained in this work indicate a low importance of particulate phases (colloids or suspended particles) for the migration behavior of U, Th and REE in waters from the Osumu Utsumi uranium mine and the Morro do ferro. However, these particles, composed mainly of ferric oxyhydrates and humic compounds, play an important role in sorption and immobilization processes. (author)

    Inadequate trophoblast invasion and the subsequent inflammatory response have been implicated in preeclampsia (PE) pathogenesis. Because MYC-induced nuclear antigen (MINA) gene expression is involved in cell proliferation and differentiation, inflammatory response modulation, and the unpaired regulation of which is associated with human diseases, we sought to investigate the connection between MINA and PE. The aim of this study was to evaluate the possible relationship between the MINA rs4857304 variant and susceptibility to PE development as well as to estimate placental MINA gene expression and its association with PE. About 242 pregnant women (126 PE cases and 116 controls) were included. MINA genotyping and gene expression were evaluated by quantitative real-time polymerase chain reaction using TaqMan probes. The G/G genotype of the MINA rs4857304 variant was associated with severe PE (p = 0.027, OR = 1.8, 95% CI = 1.8-3.2). Carriers of one G allele of the MINA rs4857304 variant exhibited a 1.7-fold increased risk of severe PE (p = 0.029, 95% CI = 1.1-3.0). MINA was underexpressed in preeclamptic placentas and MINA expression differed between the mild and severe PE groups. Differences in the expression levels of MINA were found among women with the T/T genotype of the rs4857304 polymorphism and carriers of at least one G allele (p = 0.024). PE and its severity are associated with the underexpression of placental MINA, and the G/G genotype of the MINA rs4857304 variant may modify the risk of severe PE among the PE cases evaluated.

    Mina is a JmjC family 2-oxoglutarate oxygenase with pleiotropic roles in cell proliferation, cancer, T cell differentiation, pulmonary inflammation, and intestinal parasite expulsion. Although Mina expression varies according to cell-type, developmental stage and activation state, its transcriptional regulation is poorly understood. Across inbred mouse strains, Mina protein level exhibits a bimodal distribution, correlating with inheritance of a biallelic haplotype block comprising 21 promoter/intron 1-region SNPs. We previously showed that heritable differences in Mina protein level are transcriptionally regulated. Accordingly, we decided to test the hypothesis that at least one of the promoter/intron 1-region SNPs perturbs a Mina cis-regulatory element (CRE). Here, we have comprehensively scanned for CREs across a Mina locus-spanning 26-kilobase genomic interval. We discovered 8 potential CREs and functionally validated 4 of these, the strongest of which (E2), residing in intron 1, contained a SNP whose BALB/c-but not C57Bl/6 allele-abolished both Smad3 binding and transforming growth factor beta (TGFβ) responsiveness. Our results demonstrate the TGFβ signaling pathway plays a critical role in regulating Mina expression and SNP rs4191790 controls heritable variation in Mina expression level, raising important questions regarding the evolution of an allele that uncouples Mina expression from the TGFβ signaling pathway. © 2017 The Authors.

    Mina is an epigenetic gene regulatory protein known to function in multiple physiological and pathological contexts, including pulmonary inflammation, cell proliferation, cancer and immunity. We showed previously that the level of Mina gene expression is subject to natural genetic variation linked to 21 SNPs occurring in the Mina 5' region. In order to explore the mechanisms regulating Mina gene expression, we set out to molecularly characterize the Mina promoter in the region encompassing these SNPs. We used three kinds of assays--reporter, gel shift and chromatin immunoprecipitation--to analyze a 2 kb genomic fragment spanning the upstream and intron 1 regions flanking exon 1. Here we discovered a pair of Mina promoters (P1 and P2) and a P1-specific enhancer element (E1). Pharmacologic inhibition and siRNA knockdown experiments suggested that Sp1/3 transcription factors trigger Mina expression through additive activity targeted to a cluster of four Sp1/3 binding sites forming the P1 promoter. These results set the stage for comprehensive analysis of Mina gene regulation from the context of tissue specificity, the impact of inherited genetic variation and the nature of upstream signaling pathways.

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

    Mobility options for persons suffering from paraplegia or paraparesis are limited to mainly wheeled devices. There are significant health, psychological, and social consequences related to being confined to a wheelchair. We present the Mina, a robotic orthosis for assisting mobility, which offers a legged mobility option for these persons. Mina is an overground robotic device that is worn on the back and around the legs to provide mobility assistance for people suffering from paraplegia or paraparesis. Mina uses compliant actuation to power the hip and knee joints. For paralyzed users, balance is provided with the assistance of forearm crutches. This paper presents the evaluation of Mina with two paraplegics (SCI ASIA-A). We confirmed that with a few hours of training and practice, Mina is currently able to provide paraplegics walking mobility at speeds of up to 0.20 m/s. We further confirmed that using Mina is not physically taxing and requires little cognitive effort, allowing the user to converse and maintain eye contact while walking. © 2011 IEEE

  12. Mina: a Th2 response regulator meets TGFβ.

    The JmjC protein Mina is an important immune response regulator. Classical forward genetics first discovered its immune role in 2009 in connection with the development of T helper 2 (Th2) cells. This prompted investigation into Mina's role in the two best-studied contexts where Th2 responses are essential: atopic asthma and helminth expulsion. In work focused on a mouse model of atopic asthma, Mina deficiency was found to ameliorate airway hyper-resistance and pulmonary inflammation. And, in a case-control study genetic variation at the human MINA locus was found to be associated with the development of childhood atopic asthma. Although the underlying cellular and molecular mechanism of Mina's involvement in pulmonary inflammation remains unknown, our recent work on parasitic helminth expulsion suggests the possibility that, rather than T cells, epithelial cells responding to TGFβ may play the dominant role. Here we review the growing body of literature on the emerging Mina pathway in T cells and epithelial cells and attempt to set these into a broader context. Copyright © 2014 Elsevier Ltd.

    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.

    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.

    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.

    1981-01-01

    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.

    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.

    The present work studied the viability of gamma radiation as alternative method of conservation 'minas frescal' cheese through by determining its effect on the physical-chemical properties of this product after irradiation. Cheese elaborated in the Laboratory of Food Irradiation CENA/USP, were exposed to doses of 0 (it controls); 1; 2; 3 and 4 kGy and stored under refrigeration (±5 deg C). The analysis were accomplished in the 1st, 7th and 14th day of storage considered the following parameters: acidity, pH, moisture and level of proteolysis according to methodology of Association of Official Analytical Chemists (A.O.A.C.),1995. The results revealed that the dose of 2 kGy was the most indicated for irradiation of that type of cheese, because after this treatment, the product maintained in good conditions for consumption after 14 days of storage. It was concluded that gamma radiation can be used as a method of conservation of 'minas frescal' cheese, without causing alterations in its physical-chemical characteristics. (author)

  6. 'Sensory analysis of specialty coffee from different environmental conditions in the region of Matas de Minas, Minas Gerais, Brazil

    Full Text Available ABSTRACT Specialty coffees can be differentiated in various ways, including the environmental conditions in which they are produced and the sensory composition of the drink. This study aimed to evaluate the effect of altitude, slope exposure and fruit color on the sensory attributes of cafes of the region of Matas de Minas. Sampling points were georeferenced in four altitude ranges (< 700 m; 700 ≤ x ≤ 825 m, 825 < x < 950 m and ≥ 950 m of the coffee crop; two fruit colors of var. Catuaí (yellow and red; and two slope exposures (North-facing and South-facing. Coffee fruit at the cherry stage were processed and submitted to sensory analysis. The sensory attributes evaluated were overall perception, clean cup, balance, aftertaste, sweetness, acidity, body and flavor, which made up the final score. The scores were examined by ANOVA and means were compared by the Tukey test (p ≤ 0.05. From the sensory standpoint, coffee fruits of both colors are similar, as well as the coffees from both slope exposures when these factors were analyzed separately. However, at higher altitudes, Yellow Catuaí produces coffees with better sensory quality. Similarly, coffees from North-facing slopes, at higher altitudes produce better quality cup. The altitude is the main factor that interferes with coffee quality in the area. All factors together contribute to the final quality of the beverage produced in the region of Matas de Minas.

    Full Text Available The consumer’s preference for artisanal raw milk cheeses has been growing steadily, because of its taste intensity and variation compared to pasteurized cheese. The development of flavor and aroma in raw milk cheese is governed mainly by diversified endogenous microbiota and naturals milk enzymes. The weather, altitude, native pasture and others regional characteristics allow the artisanal Minas cheese to have a typical and unique flavor. However, most of artisanal cheeses are manufactured in a rudimentary way, following technologies used by their ancestor, and this fact can cause defects in cheeses, thus resulting in economic losses for producers. Many defects may be originated from the quality of milk for manufacture, as well as quality and quantity of the ingredients used, manufacturing and ripening procedures. In this review will be presented the major defects that arise specifically in artisanal cheeses, as well as their origins, prevention and repair.

O material utilizado foi obtido de um estudo retrospectivo de casos de aborto recebidos pelo Setor de Patologia Veterinária da Universidade Federal de Lavras e de fetos necropsiados durante os anos de 2011 a 2013. De 60 fetos estudados, 30 (50% tinham lesões microscópicas. Destes, 19 (63% apresentaram lesões compatíveis com aborto por N. caninum, caracterizadas principalmente por encefalite não supurativa multifocal, necrose e gliose multifocal, assim como, miocardite e miosite não supurativa. Em 14 fetos chegou-se ao diagnóstico definitivo. Destes, cinco tiveram sua confirmação somente pela marcação IHQ e cinco foram positivos somente na PCR. Quatro fetos foram positivos tanto na IHQ quanto na PCR. Cinco fetos, provenientes do estudo retrospectivo apresentaram lesões compatíveis com N. caninum, mas a presença do protozoário não foi confirmada pela marcação IHQ. Os achados demonstram que o N. caninum é um importante agente associado ao aborto em bovinos na região sul de Minas Gerais. Para tanto, além das lesões microscópicas a associação entre a IHQ e a técnica de PCR foi essencial para a confirmação do diagnóstico.

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

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

  17. Reactivation of organophosphate-inhibited human acetylcholinesterase by isonitrosoacetone (MINA): a kinetic analysis.

    Treatment of poisoning by highly toxic organophosphorus compounds (OP) with atropine and an acetylcholinesterase (AChE) reactivator (oxime) is of limited effectiveness in case of different nerve agents and pesticides. One challenge is the reactivation of OP-inhibited brain AChE which shows inadequate success with charged pyridinium oximes. Recent studies with high doses of the tertiary oxime isonitrosoacetone (MINA) indicated a beneficial effect on central and peripheral AChE and on survival in nerve agent poisoned guinea pigs. Now, an in vitro study was performed to determine the reactivation kinetics of MINA with tabun-, sarin-, cyclosarin-, VX- and paraoxon-inhibited human AChE. MINA showed an exceptionally low affinity to inhibited AChE but, with the exception of tabun-inhibited AChE, a moderate to high reactivity. In comparison to the pyridinium oximes obidoxime, 2-PAM and HI-6 the affinity and reactivity of MINA was in most cases lower and in relation to the most effective reactivators, the second order reactivation constant of MINA was 500 to 3400-fold lower. Hence, high in vivo MINA concentrations would be necessary to achieve at least partial reactivation. This assumption corresponds to in vivo data showing a dose-dependent effect on reactivation and survival in animals. In view, of the toxic potential of MINA in animals human studies would be necessary to determine the tolerability and pharmacokinetics of MINA in order to enable a proper assessment of the value of this oxime as an antidote in OP poisoning.

    The occurrence of volcanic and pyroclastic rocks in the Mina Verdun Group is reported here. The unit represents a marine volcanosedimentary succession, made up from base to top of the following formations: Cerro de las Viboras Formation (metarhyolites), Don Mario Formation (pelites, sandstones), La Toma Formation (marls), El Calabozo Formation (stromatolitic limestones with Conophyton), Gibraltar Formation (mainly dolostones, subordinate marls and limestones) and Nueva Carrara Formation (acid lapilli-tuffs acidos and dolomitic metamarls). Three outcrop areas are known, located between Minas and Pan de Azucar, namely: Mina Verdun (stratotype), Burgueno Quarry and Paso del Molino (Arroyo Pan de Azucar). Diamictites and orthoconglomerates of the Las Ventanas Formation overly with erosional and angular unconformity the Mina Verdun Group. The age of the succession is pre-Ediacaran, and bracketed between the late Mesoproterozoic and Tonian (1300-850 Ma) according to the chemostratigraphic data and the stromatolite assemblages. Carbonates of the Mina Verdun Group show a ?13C curve at its stratotype, which is characterized by a basal negative excursion to -3.3 PDB, followed by moderately positive values in the rest of the section, representing a plateau around +2 ? PDB. In the southern part of its outcrop area, limestones of the Mina Verdun Group show more negative de ?13C and ?18O values, as well as a maniphest decoloration. These characteristics are the result of contact-metamorphism of nearby granitic plutons in that area. (author)

    The Mina Verdun Group (Precambrian) was deposited prior to the subvolcanic emplacement of a longitudinal dyke swarm of basaltic to andesitic composition (Minas Subvolcanic Swarm of the Mina Verdun quarry - Nico Perez Terrane, Minas, Uruguay). The swarm and its country rocks predated a tectono-metamorphic event that produced fragileductile shear zones associated with very low- to low-grade dislocation metamorphism. We interpreted a K-Ar whole rock datum of 485,2 ± 12,5 Ma (andesitic dyke) as a minimum cooling age in relation with late- to post-swarm emplacement deuteric alteration stage. Another K-Ar whole rock datum of 108,5 ± 2,9 Ma on a basaltic dyke was assumed here as a degasification stage, while its geological meaning is still matter of debate. The Minas Subvolcanic Dyke Swarm was intruded at high crustal levels, suggesting that the Minas region was affected by a period of extensional tectonics [es

    Mina Ratones environmental restoration project included petrological, structural,geophysical, hydrogeological and hydrogeochemical studies. The main objective of the geologic-structural and geophysical studies was the Albala granite structural characterization around the Mina Ratones uranium mine. The location of facies, fault zones (faults and dykes) as well as the distribution of some physical properties inside the rock massif was obtained for a granitic black of 900, 500, and 500 m. The geologic-structural and geophysical techniques applied to Mina Ratones provided a multidisciplinary approach for high resolution characterization of rock massif, and the structures potentially containing fluids,able to be applied to the hydrogeological modelling to a particular area. Geological studies included a detailed structural mapping of the area surrounding the mine (1:5,000 scale), the geometric, kinematics, and dynamics analysis of fractures of all scales, the petrology and geochemistry of fault rocks and altered areas surrounding fractures, and the microstructural studies of samples from surface and core lags. The construction of geostatistical models in two and three dimensions had helped to characterize the Mina Ratones rock massif showing the spatial distribution of fault zones, fracture intensity, granite composition heterogeneities, fluid-rock interaction zones, and physical properties.

    Full Text Available While most mobility options for persons with paraplegia or paraparesis employ wheeled solutions, significant adverse health, psychological, and social consequences result from wheelchair confinement. Modern robotic exoskeleton devices for gait assistance and rehabilitation, however, can support legged locomotion systems for those with lower extremity weakness or paralysis. The Florida Institute for Human and Machine Cognition (IHMC has developed the Mina, a prototype sensorimotor robotic orthosis for mobility assistance that provides mobility capability for paraplegic and paraparetic users. This paper describes the initial concept, design goals, and methods of this wearable overground robotic mobility device, which uses compliant actuation to power the hip and knee joints. Paralyzed users can balance and walk using the device over level terrain with the assistance of forearm crutches employing a quadrupedal gait. We have initiated sensory substitution feedback mechanisms to augment user sensory perception of his or her lower extremities. Using this sensory feedback, we hypothesize that users will ambulate with a more natural, upright gait and will be able to directly control the gait parameters and respond to perturbations. This may allow bipedal (with minimal support gait in future prototypes.

    The significance of the study of the characteristics of crowd behavior is indubitable for safely organizing mass activities. There is insufficient material to conduct such research. In this paper, the Mina crowd disaster is quantitatively re-investigated. Its instantaneous velocity field is extracted from video material based on the cross-correlation algorithm. The properties of the stop-and-go waves, including fluctuation frequencies, wave propagation speeds, characteristic speeds, and time and space averaged velocity variances, are analyzed in detail. Thus, the database of the stop-and-go wave features is enriched, which is very important to crowd studies. The ‘turbulent’ flows are investigated with the proper orthogonal decomposition (POD) method which is widely used in fluid mechanics. And time series and spatial analysis are conducted to investigate the characteristics of the ‘turbulent’ flows. In this paper, the coherent structures and movement process are described by the POD method. The relationship between the jamming point and crowd path is analyzed. And the pressure buffer recognized in this paper is consistent with Helbing's high-pressure region. The results revealed here may be helpful for facilities design, modeling crowded scenarios and the organization of large-scale mass activities.

    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.

    The acid mine drainage is one of the most important environmental problems associated with mining of ores containing sulfides. The treatment of these acid effluents, which contains high concentrations of dissolved metals and anions, is generally by liming. The wastes generated in the liming process may present significant toxicity and their storage in inappropriate places waiting for treatment is a common issue that requires solution. Osamu Utsumi Mine located in the city of Caldas, Minas Gerais, has been facing this problem. The residue of this mine consists of an alkaline sludge generated from the neutralization of the pH of acid mine drainage and is rich in various metals, including uranium. The main concern is the long term stability of this residue, which is in permanent contact with the acid water in the open pit. The recovery of uranium by hydrometallurgical techniques, such as acid leaching, can be a viable alternative on the reuse of this material. This study aimed at establishing a specific leaching process for the recovery of uranium present in the sludge from Caldas uranium mine. Some parameters such as solid/liquid ratio (0.09 to 0.17), time of leaching (1 to 24 hours) and concentration of sulfuric acid (pH from 0 to 3.0) were assessed. The results showed that it is possible to extract 100% of uranium present in the sludge. The concentration of U{sub 3}O{sub 8} in the residue was 0.25%, similar to the content of the vein ores which is around 0.20% to 1.0%. The best experimental leaching condition is solid/liquid ratio of 0.17, pH 1.0 and 2 hours of reaction at room temperature (25 deg C). The content of uranium in the liquor is around 440 mgL{sup -1}. The recovery of the uranium from the liquor is under investigation by ionic exchange. (author)

    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.

    Mina Ratones environmental restoration project included petrological, structural,geophysical, hydrogeological and hydrogeochemical studies. The main objective of the geologic-structural and geophysical studies was the Albala granite structural characterization around the Mina Ratones uranium mine. The location of facies, fault zones (faults and dykes) as well as the distribution of some physical properties inside the rock massif was obtained for a granitic black of 900, 500, and 500 m. The geologic-structural and geophysical techniques applied to Mina Ratones provided a multidisciplinary approach for high resolution characterization of rock massif, and the structures potentially containing fluids,able to be applied to the hydrogeological modelling to a particular area. Geological studies included a detailed structural mapping of the area surrounding the mine (1:5,000 scale), the geometric, kinematics, and dynamics analysis of fractures of all scales, the petrology and geochemistry of fault rocks and altered areas surrounding fractures, and the microstructural studies of samples from surface and core lags. The construction of geostatistical models in two and three dimensions had helped to characterize the Mina Ratones rock massif showing the spatial distribution of fault zones, fracture intensity, granite composition heterogeneities, fluid-rock interaction zones, and physical properties.

    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.

  17. A Kinematic Model for Vertical Axis Rotation within the Mina Deflection of the Walker Lane

    The Mina Deflection, at the boundary between the Central and Southern Walker Lane, spans the California-Nevada border and includes a heavily-faulted Pliocene volcanic field overlying Miocene ignimbrites. The dextral Walker Lane accommodates 25% of relative Pacific-North America plate motion and steps right across the sinistral Mina deflection. Ours and previous work shows that the Mina Deflection partially accommodates deformation by vertical-axis rotation of up to 99.9o ± 6.1o rotation since 11 Ma. This rotation is evident in latite ignimbrite of Gilbert et al. (1971), which we have formalized as three members of Tuff of Huntoon Creek (THC). The welded, basal, normal-polarity Huntoon Valley Member of THC is overlain by the unwelded to partially-welded, reversed-polarity Adobe Hills Mbr. This member includes internal breaks suggesting multiple eruptive phases, but the paleomagnetic results from each are statistically indistinguishable, meaning that they were likely erupted in rapid succession (within a few centuries of one another). THC ends with a welded member exhibiting very shallow inclination and south declination that we call Excursional Mbr. One of the upper members has been dated at 11.17 ± 0.04 Ma. These Miocene units are overlain by Pliocene basalts, Quaternary alluvium, and lacustrine deposits. Our paleomagnetic results show a gradient between the zero rotation domain and high rotation across a 20km baseline. A micropolar model, based on 25 years of earthquake data from the Northern and Southern California Seismic Network, suggest the Mina Deflection is currently experiencing transpressional seismogenic deformation (Unruh et al., 2003). Accepting Unruh's model and assuming continuous rotation since 11 Ma, we propose a kinematic model for the western Mina Deflection that accommodates 90o of vertical axis rotation from N-S to ENE-WSW oriented blocks.

Two methodologies were used to estimate the kinetic energy for each index. Thus, four erosivity values were evaluated for each month, resulting in the development of 48 ANNs. These ANNs were implemented using the software Borland Delphi 7.0. The new software was called NetErosividade MG. The program calculates the monthly and annual values of rainfall erosivity for any location in the state of Minas Gerais in an easy and fast way.

    Full Text Available The objective of the study was to evaluate the microbiological quality of pasteurized milk, Minas Frescal cheese (MFC, and bovine ground beef (BGB. A total of 74 samples were subjected to analyses of total coliforms, fecal coliforms, Escherichia coli and Salmonella sp. Moreover, the MFC samples were subjected to analysis of coagulase-positive staphylococci (CPS and Listeria monocytogenes. All samples presented total coliforms, 81.6 % of the samples had values above the recommended for fecal coliform, and high incidence of E. coli. 75.0 % of the MFC samples were not in accordance with the legislation for CPS. All samples showed absence of Salmonella sp. and L. monocytogenes. These results showed that food of animal origin commercialized in the region of Minas Gerais is unfit for human consumption due to low microbiological quality. Therefore, there is need for adoption of good manufacturing practices and efficient sanitation to minimize the risk of transmission of foodborne pathogens by these foods.

    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.

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

    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.

    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

    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.

Potosí fue el destino de la inmigración masiva durante su florecimiento económico y una de las ciudades más grandes en el mundo occidental en 1610. En las minas se desarrollaba un código separado, con un léxico especializado que contenía palabras de lenguas diferentes. Este léxico fue tan distinto que el primer vocabulario de lengua de minas fue escrito en 1610, y muchos han seguido desde esa fecha. El quechua jugaba un papel clave como lengua intermediaria entre dos formas de hablar: el lenguaje minero indígena de los yanaconas y mingas, probablemente una mezcla de castellano y quechua, y el lenguaje de los mitayos, posiblemente una mezcla de aimara y quechua. Las semejanzas entre aimara y quechua deben haber contribuido a esta posibilidad de lengua intermediaria.

    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.

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

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

    It is generally known that histone demethylases regulate gene transcription by altering the methylate status on histones, but their roles in cancers and the underlying molecular mechanisms still remain unclear. MYC-induced nuclear antigen (MINA) is reported to be a histone demethylase and highly expressed in many cancers. Here, for the first time, we show that MINA is involved in glioblastoma carcinogenesis and reveal the probable mechanisms of it in cell-cycle control. Kaplan-Meier analysis of progression-free survival showed that high MINA expression was strongly correlated with poor outcome and advancing tumor stage. MINA knockdown significantly repressed the cell proliferation and tumorigenesis abilities of glioblastoma cells in vitro and in vivo that were rescued by overexpressing the full-length MINA afterwards. Microarray analysis after knockdown of MINA revealed that MINA probably regulated glioblastoma carcinogenesis through the predominant cell-cycle pathways. Further investigation showed that MINA deficiency led to a cell-cycle arrest in G1 and G2 phases. And among the downstream genes, we found that cyclins and cyclin-dependent kinases were directly activated by MINA via the demethylation of H3K9me3.

    This article describes the investigations of redox fronts performed at the Osamu Utsumi mine. Results obtained by modelling groups on the rate of movement of the redox fronts and on the chemical reactions involved are discussed. Some of the most important rockwater interactions which occur at redox fronts can be modelled reasonably well but the complex redox chemistry of elements like sulphur is poorly simulated. The observed enrichment of many trace elements close to the redox fronts could be of significance for high-level waste repositories, but cannot be quantified by existing models.

    Full Text Available OBJETIVO: Avaliar a disponibilidade de medicamentos essenciais em localidades com índice de desenvolvimento humano OBJECTIVE: To investigate the availability of essential drugs in municipalities with a human development index < 0.699. METHODS: We surveyed 69 institutions, including municipal pharmacies, public clinics, private and philanthropic health units, and commercial pharmacies, in 19 municipalities of the state of Minas Gerais, Brazil. The municipalities were chosen according to the following selection criteria: (1 a human development index (HDI < 0.699 (the HDI for the entire state of Minas Gerais in 1991 in the microregion where the municipality was located; (2 the municipality had to be the seat of government for the microregion where it was located; (3 there had to be at least two eligible institutions (belonging to the public, private, or philanthropic sectors in full functioning in the municipality during the survey period. Health professionals who were directly responsible for stock control and drug dispensation at the institutions surveyed were interviewed. Institutional documents and records were also reviewed. A list of 21 tracer essential drugs, which were selected among the drugs most widely employed in the State of Minas Gerais’ Basic Pharmacy Program, was used to measure availability. The availability of each tracer drug was calculated at the time of the site visit and for the 12-month period immediately before the survey. In addition, the availability of tracer drugs was calculated for each type of institution surveyed.

    The Master in Nuclear Engineering and Applications (MINA) was born to build up a bridge between University education and the technical skills demanded by nuclear industry and organizations, particularly in Spain. Motivated by nuclear renaissance, knowledge preservation and the bases of the European Education area, the new approach adopted to accomplish such a challenge has been heavily based on a professional profile defined by the Spanish nuclear community. The first edition success (MINA-2008) has been assessed through a set of indicators, which encompass a broad range of aspects, from the number of registrations to the employment rate. This paper summarizes and discusses such an assessment. Additionally, a critical thorough review has allowed identifying a few aspects that could be improved. All the lessons learned have been translated into specific measures implemented in the MINA-2009 edition. Among the indicators, participation and industrial support were considered of utmost importance. MINA-2008 had 18 students, out of which 60% were financially supported to some extent thanks to the nuclear industry and organizations (during the conduction of the master project, this support was even enhanced). Beyond the economic contribution, nuclear companies and institutions were strongly involved in all the phases of MINA-2008, from the definition of the program up to the supervision of more than 70 % of the master projects. As a result of the lessons learned, the subjects have been grouped in modules and a more practical approach has been pursued in the teaching/learning process. (authors)

    Bladder cancer (BLCa) is a severe urological cancer of both men and women that commonly recurs and once invasive, is difficult to treat. MINA-05 (CK Life Sciences Int'l, Hong Kong) is a derivative of complex botanical extracts, shown to reduce cellular proliferation of bladder and prostate carcinomas. We tested the effects of MINA-05 against human BLCa cell sublines, B8, B8-RSP-GCK, B8-RSP-LN and C3, from a transitional cell carcinoma, grade IV, to determine the molecular targets of treatment by observing the cellular protein profile. Cells were acclimatised for 48 h then treated for 72 h with concentrations of MINA-05 reflecting 1/2 IC(50), IC(50) and 2 x IC(50) (n = 3) or with vehicle, (0.5% DMSO). Dose-dependant changes in protein abundance were detected and characterised using 2-dimensional electrophoresis and MS. We identified 10 proteins that underwent changes in abundance, pI and/or molecular mass in response to treatment. MINA-05 was shown to influence proteins across numerous functional classes including cytoskeletal proteins, energy metabolism proteins, protein degradation proteins and tumour suppressors, suggesting a global impact on these cell lines. This study implies that the ability of MINA-05 to retard cellular proliferation is attributed to its ability to alter cell cycling, metabolism, protein degradation and the cancer cell environment.

Os ensaios foram realizados após a etapa de enformagem e prensagem, para facilitar a reprodutibilidade estrutural dos queijos. Utilizou-se vácuo de 85,3kPa (Pabsoluta =16kPa, aplicado intermitentemente, intercalado com a recuperação da pressão atmosférica na câmara. Após períodos pré-estabelecidos, a câmara foi aberta e os queijos foram pesados e secionados, de modo a permitir a determinação da distribuição de sal no interior dos mesmos pelo método de Mohr. A salga por IV permitiu a obtenção de queijos com 1,6% em massa de sal em 15 minutos, contra 2,5 horas da salga convencional. Além disso, a distribuição de sal nos queijos salgados por IV foi mais homogênea do que nos queijos salgados por imersão em salmoura a pressão atmosférica. Esses resultados indicaram que a salga de queijos tipo Minas por IV pode ser uma boa alternativa de processamento, tanto do ponto de vista econômico como tecnológico.Minas cheese salting by vacuum impregnation was studied using cylindrical cheese samples of about 500 g and 120 ' 60mm (radius ' height, that were immersed in a hermetic chamber with 22g NaCl/100g, where sub-atmospheric pressures were applied.

    The production of Minas Traditional Serro Cheese without the Good Manufacturing Practices compromises the quality of the product, offering risks to consumer’s health. Aiming to identify the main points of contamination of the milking and cheese manufacturing process and their correlation with the microbial contamination, a structured questionnaire about the hygienic and sanitary conditions of cheese production was applied to cheese producers. In addition, samples of cheese were collected and analyzed for coliforms 30ºC, Escherichia coli, Staphylococcus aureus, and aerobic mesophilic bacteria. The points identified, presenting correlation with microbiological analysis, were insalubrity of the place where the cheese was manufactured, presence of domestic animals, and the hygiene of food handlers. It is essential to qualify producers to adopt corrective and preventive measures to minimize or avoid contamination of the Minas Traditional Serro Cheese.

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

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

    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.

    GPS is a critical sensor for Unmanned Aircraft Systems (UASs) due to its accuracy, global coverage and small hardware footprint, but is subject to denial due to signal blockage or RF interference. When GPS is unavailable, position, velocity and attitude (PVA) performance from other inertial and air data sensors is not sufficient, especially for small UASs. Recently, image-based navigation algorithms have been developed to address GPS outages for UASs, since most of these platforms already include a camera as standard equipage. Performing absolute navigation with real-time aerial images requires georeferenced data, either images or landmarks, as a reference. Georeferenced imagery is readily available today, but requires a large amount of storage, whereas collections of discrete landmarks are compact but must be generated by pre-processing. An alternative, compact source of georeferenced data having large coverage area is open source vector maps from which meta-objects can be extracted for matching against real-time acquired imagery. We have developed a novel, automated approach called MINA (Meta Image Navigation Augmenters), which is a synergy of machine-vision and machine-learning algorithms for map aided navigation. As opposed to existing image map matching algorithms, MINA utilizes publicly available open-source geo-referenced vector map data, such as OpenStreetMap, in conjunction with real-time optical imagery from an on-board, monocular camera to augment the UAS navigation computer when GPS is not available. The MINA approach has been experimentally validated with both actual flight data and flight simulation data and results are presented in the paper.

    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)

    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)

    In the middle southern portion of the Minas Gerais state a 60 Km long and 12 Km wide tungsten belt was discovered, and related to the amphibolitic rocks of the Barbacena Greenstone. Tungsten, present as scheelite, is associated with amphibolites, amphibole schists and amphibole gneisses, with chemical characteristics indicating an igneous origin. Chemical analyses on pan concentrates by I.C.P. showed high values on lead, tin, yttrium, lanthanum, cerium and zirconium, and average values for zinc and copper. The scheelite mineralization is probably strata bound and has a possible submarine exhalative origin. (author)

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.

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

    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 population dynamics of Staphylococcus spp. was studied during the ripening of Canastra Minas cheese at three farms located in the State of Minas Gerais, Brazil. The presence of coagulase (coa, thermonuclease (nuc, and enterotoxin (sea, seb, sec, and sed genes was investigated in Staphylococcus strains isolated during the 60-day cheese-ripening period. The presence of the staphylococcal enterotoxins A, C, and D was also investigated in the cheese samples. Cheese samples that were matured for 0, 7, 15, 30, and 45 days presented staphylococci counts from 10³ to 10(8cfu/g. All isolates considered coagulase-positive by physiological tests had the coa gene. However, no association was observed between the results obtained with biochemical tests and those obtained by PCR using gene-specific primers for coagulase-negative strains. Coagulase and thermonuclease genes occurred simultaneously in 41.3% of Staphylococcus spp. tested. None of the investigated Staphylococcus strains expressed enterotoxins SEA, SEB, SEC, and SED. Enterotoxins A, C, and D were not detected in any of the cheese samples.

    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 The acquisition of food from family farms can provide an adequate and safe food to students, and respect the culture, traditions and promote social control, food security and sustainable development for the city of Caxambu, Minas Gerais. Was evaluated and monitored to the supply of agricultural products for the feeding of 2,054 students from public schools in Caxambu, Minas Gerais, for family farmers in the town of Caxambu, during the academic year 2010. We performed a descriptive analysis. Two farmers have provided chayote, cabbage, cassava, cabbage, ripe pumpkin, zucchini, parsley and lettuce twice a week, excellent visual quality and the amount provided for in cronogram. Cost of family farms was 6.92% less than the amount allocated to the municipality by FNDE / PNAE. It was found that the municipality is not serving Law No. 11,947, which has a minimum of 30% for the acquisition of genres from family farms. Although this program has been little explored in 2010, the administration's efforts, in partnership with EMATER were made to motivate the participation of more farmers, by the insertion of new food in school menus.

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.

    Full Text Available Various ceramic supports besides standard soda-lime glass have been utilized as substrates for deposition of molybdenum and copper indium diselenide layers (substrate/Mo/CuInSe2 heterostructures for application in thin film photovoltaic solar cells. Molybdenum layers have been prepared simultaneously onto the different substrates by electron gun assisted evaporation. Subsequently, CuInSe2 thin films have been obtained by direct electrodeposition onto the Mo-coated substrates. The influence of the substrate characteristics onto the optical and structural properties of the developed materials has been determined to evaluate the possibility of substituting the commonly utilized glass by ceramics that can wide the applications of these photovoltaic systems. The obtained results indicate that the scattering factor and the structural stress in the layers are minimized when the morphological characteristics of the ceramic are close to those of the standard glass substrates.

    Land-use/land-cover change (LUCC) is a major cause of environmental transformation. Distant drivers, often associated with emerging markets for specific products, are now being considered one of the main factors of LUCC and are gaining attention in land change science. Consumers show an increasing interest in local and quality food, certified for its origin and its environmental production standards. A kind of agricultural product certification, Geographic Indication, identifies a product as originating from a specific region where a given quality, reputation or characteristic is attributed to its geographical origin. Sustainable land use is potentially an indirect effect of Geographic Indication, as it requires better land management in order to preserve the natural resources associated with the unique characteristics of the certified product. Located in the southern region of the state of Minas Gerais in Brazil is the region of Mantiqueira de Minas, considered one of the most important regions for the production of specialty coffees in Brazil. In 2011, the region's tradition and reputation were recognized with a Geographic Indication, the second given for coffee regions in the country. To explore the full potential of this area for producing coffees with higher quality and meet the growing demand of this new international market, which aggregates value at specialty coffees, it became fundamental to understand the coffee environments of the region, the "terroirs" where these coffees are obtained. Geotechnology can give a significant contribution in filling this gap. This work is part of a research project that made a detailed characterization of the region's coffee agroecosystems. Geotechnologies were employed to map the areas occupied by coffee plantations by using RapidEye satellite images and SPRING and ArcGIS software. All the segments of the environment were characterized and mapped in detail and the relations with coffee quality were evaluated. The results

    Vaughn, Kevin J.; Grados, Moises Linares; Eerkens, Jelmer W.; Edwards, Matthew J.

    2007-12-01

    Mina Primavera, a hematite (Fe2O3) mine located in southern Peru, was exploited beginning approximately 2,000 years ago by two Andean civilizations, the Nasca and Wari. Despite the importance of hematite in the material culture of the ancient Americas, few hematite mines have been reported in the New World literature and none have been reported for the Central Andes. An estimated 3,710 tonnes of hematite were extracted from the mine for over 1,400 years at an average rate of 2.65 tonnes per year, suggesting regular and extensive mining prior to Spanish conquest. The hematite was likely used as a pigment for painting pottery, and the mine demonstrates that iron ores were extracted extensively at an early date in the Americas.

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

    The Brazilian state of Minas Gerais is a species-rich territory about as large as France, which houses the headwaters of some of the most important rivers in Brazil, as well as a variety of phytogeographic domains, with a poorly known insect fauna. Here, a synopsis of the bee species included in the genera Colletes Latreille, 1802 and Rhynchocolletes Moure, 1943 (Colletidae: Colletinae) occurring in this state is presented, including synonymies, diagnoses, redescriptions and identification keys to females and males of the eight recognized species, including one described as new. These species are Rhynchocolletes albicinctus Moure, 1943; Colletes altimontanus Ferrari & Silveira sp. nov.; C. argentinus Friese, 1908 stat. rev., C. meridionalis Schrottky, 1902; C. ornatus Schrottky, 1902; C. petropolitanus Dalla Torre, 1896; C. rufipes Smith, 1879; and C. rugicollis Friese, 1900. Colletes extensicornis Vachal, 1909 is here proposed to be a junior synonym of C. meridionalis.

    Full Text Available This research sought to demonstrate the level of dependence of Minas Gerais municipalities on the Municipalities Participation Fund (FPM. To achieve this goal we demonstrated the representativeness of FPM in the financing structure of municipalities, measured by dividing the revenue from FPM and the municipal current revenue. It was found that the level of dependence of the vast majority of municipalities is higher than 50%, ie, the FPM resources represent the main source of municipal funding, especially for those with less than 20,000 inhabitants. Regarding geographical location, it was found that the regions of Zona da Mata and Vale do Rio Doce have the highest concentration of municipalities that have high dependence on FPM. The average population in these municipalities is 3,202 inhabitants, which leads to the conclusion that the dependence of FPM is directly related to the size of the municipality.

    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

    An epidemiological survey was carried out in 3,344 people of an urban town in Lagamar, Minas Gerais, Brazil--during 1992-1993, to evaluate the main risk factors related to taeniasis and cysticercosis. A total number of 875 (78.9%) houses were visited and 1080 (32.3%) subjects were clinically examined. Poor sanitary conditions were positively associated with former history of taeniasis or seizures in households (p < 0.05). It was remarkable the positive relationship between taeniasis and seizures when households were questioned and subjects were clinically evaluated (p < 0.05). The relative risk of seizures was 2.3 between households and 1.7 for individuals clinically examined respectively. The breeding of swine nearby and the chronic carriers of taeniasis are determinant factors in the maintenance of the epidemiological link between taeniasis and cysticercosis in endemic areas.

    Eduardo A. Haddad

    2007-06-01

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

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

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

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

    Full Text Available An epidemiological survey was carried out in 3,344 people of an urban town in Lagamar, Minas Gerais, Brazil - during 1992-1993, to evaluate the main risk factors related to taeniasis and cysticercosis. A total number of 875 (78.9% houses were visited and 1080 (32.3% subjects were clinically examined. Poor sanitary conditions were positively associated with former history of taeniasis or seizures in households (p < 0.05. It was remarkable the positive relationship between taeniasis and seizures when households were questioned and subjects were clinically evaluated (p < 0.05. The relative risk of seizures was 2.3 between households and 1.7 for individuals clinically examined respectively. The breeding of swine nearby and the chronic carriers of taeniasis are determinant factors in the maintenance of the epidemiological link between taeniasis and cysticercosis in endemic areas.

    Full Text Available Aiming to know which local characteristics influence the own tax revenues of municipalities in Minas Gerais, the bibliographic referential of this article versa on federalism and fiscal decentralization, indicating variables identified in the literature as determinants of municipal tax collection. The own tax revenues depends mainly on municipal tax bases and the rates levied on these bases. Thus, the municipality's income, as well as the weight of urban activities and the degree of formalization of economic activity, determine the size of this tax base and consequently the amount of funds raised. To analyze the local characteristics, secondary data were collected on the fiscal capacity of Minas Gerais municipalities for 2010, in view of the availability of data for this year. Was used factor analysis to group the variables, and quantile regression (RQ to check the effect of these in different stages of Municipal Own Revenues (MOR. Were obtained three factors: "Economic Aspects"; "Structural Aspects" and "Financial Aspects", which grouped the variables according to the correlation shown between them. With the RQ could be seen that these factors affect differently the quantile MOR (q.10, q.25, q.50, q.75 and q.90, and the highest rates are attributed to higher own tax revenues levels, demonstrating that these factors are most influential in the municipalities of higher own tax revenues. Knowing the conditions of own revenues of municipalities allows the public administration to implement actions to avoid the tax collection inefficiency, promoting the main economic activities that make up your tax base.

    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.

    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.

    The enzyme-linked immunosorbent assay (ELISA) has been used as a standard tool for monitoring food and animal feed contamination from the carcinogenic fumonisin B1 (FB1). Unfortunately, ELISA is not always efficient due to the instability of the antibody and enzyme components in the immunoassay, the presence of natural enzyme inhibitors in the samples and the high levels of non-specific protein binding. Additionally, the production of antibodies for ELISA can be time-consuming and costly, due to the involvement of animals in the manufacturing process. To overcome these limiting factors, a molecularly imprinted nanoparticle based assay (MINA) has been developed, where the molecularly imprinted nanoparticles (nanoMIPs) replace the primary antibody used in a competitive ELISA. Herein, computational modelling was used to design the nanoMIPs by selecting monomers that specifically interact with FB1. The affinity of the monomers to FB1 was verified by measuring their binding in affinity chromatography experiments. The nanoMIPs were produced by solid phase synthesis and the results showed that nanoMIPs had a hydrodynamic diameter of around 249 ± 29 nm. The assay tested in model samples is highly selective and does not show cross-reactivity with other mycotoxins such as fumonisin B2 (FB2), aflatoxin B1 (AFB1), citrinin (CTT), zearalenone (ZEA), and deoxynivalenol (DON). The MINA allows the detection of FB1 in the concentration range of 10 pM-10 nM with a detection limit of 1.9 pM and a recovery of 108.13-113.76%.

    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.

    Agricultural reclamation activities during the last few decades in the Western Nile Delta have led to great changes in the groundwater levels and quality. In Egypt, changing the desert land into agricultural land has been done using transferred Nile water (through irrigation canal systems) or/and groundwater. This research investigates the hydrogeochemical changes accompanying the reclamation processes in the small basin of Abu Mina, which is part of the Western Nile Delta region. In summer 2008, 23 groundwater samples were collected and groundwater levels were measured in 40 observation wells. Comparing the groundwater data of the pre-reclamation (1974) and the post-reclamation (2008) periods, groundwater seems to have been subjected to many changes: rise in water level, modification of the flow system, improvement of water quality, and addition of new salts through dissolution processes. Generally, Abu Mina basin is subdivided into two areas, recharge and discharge. The dissolution and mixing were recognized in the recharge areas, while the groundwater of the discharge region carries the signature of the diluted pre-reclamation groundwater. The salts of soil and aquifer deposits play an important role in the salt content of the post and pre-reclamation groundwater. NaCl was the predominant water type in the pre-reclamation groundwater, while CaSO4, NaCl and MgSO4 are the common chemical facies in the post-reclamation groundwater. The post-reclamation groundwater mostly indicates mixing between the pre-reclamation groundwater and the infiltrated freshwater with addition of some ions due to interaction with soil and sediments.

  7. Structure of the Mina Deflection in Mono Lake, CA: Inferences from Paleoseismology

    Science.gov (United States)

    Sangani, Radhika Chandrakant

    Walker Lane, a zone of transcurrent faulting along the Sierran range front, is dominated by NNW trending normal faults. Within the Walker Lane, the Mina Deflection is a region of structural anomaly, where a significant component of regional displacement and seismicity is transferred from NNW-trending faults to ENE-trending faults of the Excelsior-Coledale domain. Geographically, the western boundary of the Mina Deflection lies along the western margin of Mono Basin. This is kinematically implied by the distributed tensional and shear stress in the NNW- and ENE- trending faults of the region. Transfer of strain from the NNW-trending, right-lateral oblique slip faults to the ENE-trending, primarily left-lateral faults is poorly understood. The nature of this transfer is complicated by the presence of the young volcanics of Mono Lake at the stepover bend. I undertook detailed study of the sub-km scale geometry and kinematics of the stepover bend, and its relation to nearby recent magmatic fluid flow within the Mono Lake. Fault orientations, slip rates and ages of most recent events allow for understanding strain transfer between faulting and volcanism. The results suggest that strain is transferred from the outer arc to the inner arc of the stepover bend. Within the inner arc, the magmatism on Paoha Island seems to have arisen from a sill-like intrusion. Furthermore, strain transfer is accomplished through sets of faults and fissures that variously act as large-scale Reidel shears and tension gashes allowing the migration of magmatic fluids from depth.

    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.

    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.

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.

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

    Full Text Available 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.

    The succession exposed in the Burgueno Quarry, in the vicinity of Nueva Carrara (Maldonado, Uruguay), is here assigned to the Mina Verdun Group. It is composed, from base to top, by meta marls, calcareous breccias and limestones, stromatolitic limestones and massive dolostones. Exposed thickness exceeds 110 m. Stromatolites assigned to the group Conophyton occur in the stromatolitic limestones (El Calabozo Formation). Stromatolites are characterized by straight to sinuous columns, showing circular to elliptical transverse sections 1.5 to 26 cm in maximum diameter. Height of columns exceeds 50 cm. The stromatolitic laminations are well preserved. Sedimentary environment for this unit is inferred as sub tidal, under low energy conditions. The Las Ventanas Formation overlies with angular and erosional unconformity the Mina Verdun Group at Burgueno Quarry. The Las Palmas Formation is tentatively correlated with the Las Ventanas Formation, on the basis of stratigraphic relationships and lithologic similarity. Considering the data presented here, it is envisaged that the Lavalleja/Fuente del Puma Group is not part of the basement of the Las Ventanas Formation. A Proterozoic, pre-Vendian age is postulated for the Mina Verdun Group, thus older than ca. 600 Ma [es

    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.

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.

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

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

As características mais evidentes são: algumas fôlhas inferiores com os lobos lobulados e levemente peitadas; flores maiores, principalmente as masculinas, e de côr verde-amarelada na face externa; presença do disco bastante carnoso nas flores femininas, que durante a formação do fruto aumenta consideravelmente de tamanho; forma do fruto de seção acentuadamente trígona, enquanto que na M. Jolyana é circular. As diferenças morfológicas permitem concluir tratar-se de duas espécies diferentes, embora ambas sejam da mesma formação geográfica, Serra da Mantiqueira. Provavelmente uma derivou a outra. A observação citológica em tecido somático mostrou possuir a espécie 2n = 36 cromossomos, como a M. jolyana.A new species of Manihot, named M. handroana was originally collected in the State of Minas Gerais, Brazil. This new species is related to M. jolyana N. D. Cruz, but differs from the latter in vegetative and floral characters. The upper part of its branches has less pilosity and the basal part is glabrate. The stipules are linear and smaller than M. jolyana, without glandulous teeth. The limb is deeply divided resulting in a more reduced disk, with cuspidate lobe apices and more glabrate upper surface. Some lower leaves show lobulation of the lobes and are slightly peltate. This plant also presents a scale-from expansion of petiole extremity in unlobulated leaves, as M. jolyana. The perianth of masculine and feminine flowers is larger, and of yellowish green color on its external part. The most evident character is the fleshy disk in feminine flowers, which increases in size during fruit development. The fruit shape is markedly triangulate, while in M. jolyana it is circular. The chromosome number for M. handroana is 2n = 36, as in M. jolyana.

    This report consists of three parts. Part 1 discusses a field study conducted in an area of enhanced, natural radioactivity to assess the soil to edible vegetable concentration ratios (CR = concentration in dry vegetable/concentration in dry soil) of Th-232, Th-230, Ra-226, Ra-228, and the light rare earth elements (REE's), La, Ce, and Nd. Twenty-eight soil, and approximately 42 vegetable samples consisting of relatively equal numbers of seven varieties, were obtained from 11 farms on the Pocos de Caldas Plateau in the state of Minas Gerais, Brazil. This region is the site of a major natural analogue study to assess the mobilization and retardation processes affecting thorium and the REE's at the Morro do Ferro ore body, and uranium series radionuclides at the Osamu Utsumi open pit uranium mine. Thorium (IV) serves as a chemical analogue for quadrivalent plutonium, the light REE's (III) as chemical analogues for trivalent americium and curium, and uranium (VI) as an analogue for transuranics with stable oxidation states above IV, e.g., Pu(VI). Part 2 includes our final measurement results for naturally occurring light rare earth elements (REE's include La, Ce, Nd, and SM), U-series and Th-series radionuclides in adult farm animal tissues, feeds and soils. Our findings on soil-to-tissue concentration ratios (CR's) and the comparative behavior of these elements in farm animals raised under natural conditions by local farmers are presented. Part 3 summarizes our findings to date on the distribution and mobilization of Th-232, light rare earth elements (LREE), U-238 and Ra-228 in the MF basin. Estimates of first order, present day, mobilization rate constants resulting from ground water solubilization and seepage/stream transport are calculated using revised inventory estimates for the occurrence of these elements in the ore body and annual flux estimates for the transport of these elements away from the ore body. 151 refs., 20 figs., 40 tabs.

    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.

    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 Lepidoptera species were monitored in a plantation of Eucalyptus grandis in the Municipality of Bom Despacho, State of Minas Gerais, Brazil from March 1987 to February 1992. A total of 547 species were collected and divided in: primary pests: 13; secondary pests: 20; species without defined importance to eucalyptus: 79; and non-identified species: 435. These four groups had a mean of 5231.29; 338.18; 438.16 and 2222.87 individuals with a total of 8229.87 individuals collected per trap. The number of species without defined importance to eucalyptus, and non-identified species, increased during the collecting period of five years while those of primary and secondary pests showed similar numbers in all years. The most collected primary pests Thyrinteina arnobia Stoll and Stenalcidia sp. (Geometridae showed higher frequencies during the driest and coldest periods of the year, whereas Psorocampa denticulata Schaus (Notodontidae was most frequent during periods of higher rainfall. Species of groups III and IV increased in diversity with eucalyptus age. This area has a high probability of outbreaks of eucalyptus defoliating caterpillars, especially T. arnobia. For this reason, lepidopteran pests should be monitored in this plantation during the driest and coldest periods of the year, when they can reach population peaks. Rev. Biol. Trop. 54(2: 553-560.

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

    Full Text Available Chemical analysis of turmeric (Curcuma longa L cultivated in eight different cities in the state of Minas Gerais, Brazil was carried out. The levels of curcuminoid pigments varied from 1.4 to 6.14 g/100 g and of volatile oil from 0.97 to 7.55 mL/100 g (dry basis. Samples from Patrocínio, Arinos and Brasilândia contained higher pigment levels compared to the others. The sample from Patrocínio contained the highest volatile oil content. The mean levels of ethyl ether extract, protein, fiber, ash and starch were 8.51, 7.01, 7.22, 7.81 and 39.87 g/100 g dry basis, respectively. Laboratory extraction of flavour free oleoresin was performed in triplicate. A higher yield of pigment in the oleoresin was obtained when the volatile oil was extracted with water vapor and the oleoresin with ethanol. The oleoresin obtained was free of flavour and could be used in a wider range of food applications.Análise química de cúrcuma (Curcuma longa L provenientes de oito municípios do Estado de Minas Gerais - Brasil foi efetuada.

    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. The highest animal prevalences observed for the region Sul e Sudoeste (stratum 5, region Zona da Mata (stratum 4 and region Central (stratum 3 were significantly different from the lowest ones at region Triângulo Mineiro (stratum 7, region Noroeste, Norte, e Nordeste (stratum 1 and region Leste (stratum 2. The presence of bovine tuberculosis was associated with animal purchase from cattle traders (OR?=?2.59 [95% CI: 1.28 – 5.20], higher yield intensive dairy (OR?=?7.55 [95% CI: 1.89% – 30.09%] and non-intensive dairy production (OR?=?3.58 [95% CI: 1.06% – 12.04%], as well as with herds with 30 or more cows (OR?=?1.97 [95% CI: 1.02 – 3.80]. Non-specific reactors to the CCTT were found in 95.07% (95% CI: 94.05% - 96.09% of the herds. Therefore, the state of Minas Gerais should implement surveillance systems for the

    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.

    Full Text Available Calcium modified PbTiO3 thin films have been prepared on platinized Si, MgO and SrTiO3 substrates. The films were deposited from a sol-gel solution with a concentration of 0.3 M and with a 10% excess of PbO. Two deposits of this solution on the substrates were made by spin-coating, crystallizing each of them by a Rapid Thermal Processing. The resulting films present a single (Pb,CaTiO3 perovskite phase. All the films are textured, but the films deposited on MgO and SrTiO3 show a preferred orientation in the polar direction of the perovskite. As a result of this orientation, pyroelectric coefficients were measured, without any poling, for the films on MgO and SrTiO3. Pyroelectric measurements indicate the application of these films in infrarred sensors.Se han preparado láminas delgadas de PbTiO3 modificado con calcio sobre substratos de Si, MgO y SrTiO3 electrodados con Pt. Las películas se depositaron a partir de una solución sintetizada por sol-gel, con concentración 0.3 M y con un 10 % en exceso de PbO. En cada lámina se hicieron dos depósitos de la solución sobre el substrato mediante la técnica de “spin-coating”, cristalizando cada uno de ellos con un tratamiento térmico rápido. Todas las láminas resultantes presentaban como única fase cristalina la perovskita de (Pb,CaTiO3. Las láminas presentaron una cierta textura, observándose una orientación preferente en la dirección polar en el caso de las películas depositas sobre MgO y SrTiO3. Como resultado de esta orientación, se midieron coeficientes piroeléctricos, sin polarización previa, en las láminas sobre MgO y SrTiO3. Las medidas piroeléctricas de estos materiales evidencian su utilidad en dispositivos para sensores de infrarrojo.

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

    This article discusses the impact of smallpox and vaccination practices used against the disease used in the province of Minas Gerais, in Brazil, during the Imperial Period (1822-1889). Despite the existence of services responsible for the organization and dissemination of the vaccine in the country since the early 19th century, some administrative and cultural factors, as identified in documents produced by the province's public health authorities at the time, had a negative impact upon the full implementation of both practice and organization of services aimed at the dissemination of smallpox vaccination. Based upon historiographic sources, it is argued that despite the trend towards centralization observed at different governmental spheres during the structuring of the Imperial State, in particular, in the provision of vaccination services, there was a prevailing disharmony between the different agencies responsible for the implementation and management of such services. A further contributor to the difficulties in the service implementation was the resistance of the population to submit to the vaccination, a phenomenon that can be best understood through examination of the social construction of perceptions about diseases and the vaccination method used against the smallpox.

    In addition to personal interviews, laboratory analyses were performed using 80 water samples from 45 rural areas that are crossed by the Agua Limpa and Santa Cruz streams close to the city of Lavras, southern Minas Gerais State. The results allowed comparing the quality of water used for agriculture and the identification of determinant factors. The Agua Limpa stream mostly crosses an area used primarily for housing and characterized by low schooling. Many houses are supplied by shallow water wells and have ordinary cesspits for human waste disposal. All springs are polluted. The Santa Cruz stream displays a different scenario. The land is used mostly for agricultural purposes. Most owners live in town, with widely varied levels of school, from none to university. The houses are supplied by surface water. Most of the springs are polluted. The perception by both home and land owners concerning quality of the drinking water is determined solely by the water's physical and organoleptic characteristics. Sanitary parameters are not taken into account. Moreover, there is no relationship between fecal contamination and the type of spring. Land use and anthropic activity are far more important than the type of spring for water quality.

  16. SIMULATION MODELLING OF VITÓRIA-MINAS CLOSED-LOOP RAIL NETWORK

    Full Text Available This paper presents a closed loop simulation model that represents the mining logistics chain of the Vitória Minas Railway (VMR, Brazil. The simulator includes the loading process, circulation of loaded trains, unloading of ores for external and internal markets and the distribution of empty trains for new loads. General cargo and passengers trains are also included in the model, which, along with the queues formed in the circulation and the preventive and corrective maintenance of rolling stock, tracks and equipment, interfere with the transportation of iron ore. The primary objective of the iron ore transport is to meet the daily loading and unloading schedules and minimize queues by maximizing the operations at the loading and unloading points. The VMR simulator developed uses macro-mesoscopic approach with Monte Carlo simulation. To validate the simulator, we used actual data of the railway and compared with reality. We obtained a very good adhesion to the value of 2.9% for the validation scenario (Scenario 1 and 3.4% for the scenario with reducing the number of lots of wagons (Scenario 2. We concluded with this simulation that it is possible to reduce the number of GDE wagons without reducing the current level of productivity of the rail system.

    Visceral leishmaniasis (VL) is associated with interstitial pneumonitis according to histology and radiology reports. However, studies to address the functional impact on respiratory function in patients are lacking. We assessed pulmonary function using noninvasive spirometry in a cross-sectional study of hospitalized adult VL patients from Minas Gerais, Brazil, without unrelated lung conditions or acute infections. Lung conditions were graded as normal, restrictive, obstructive, or mixed patterns, according to Brazilian consensus standards for spirometry. To control for regional patterns of lung function, we compared spirometry of patients with regional paired controls. Spirometry detected abnormal lung function in most VL patients (70%, 14/20), usually showing a restrictive pattern, in contrast to regional controls and the standards for normal tests. Alterations in spirometry measurements correlated with hypoalbuminemia, the only laboratory value indicative of severity of parasitic disease. Abnormalities did not correlate with unrelated factors such as smoking or occupation. Clinical data including pulmonary symptoms and duration of therapy were also unrelated to abnormal spirometry findings. We conclude that the severity of VL is correlated with a restrictive pattern of lung function according to spirometry, suggesting that there may be interstitial lung involvement in VL. Further studies should address whether spirometry could serve as an index of disease severity in the management of VL. © The American Society of Tropical Medicine and Hygiene.

    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.

Datos secundarios, obtenidos en la Tarjeta de la Mujer Embarazada y en las Tarjetas de Notificación, fueron utilizados con miras a una mejor comprensión de los discursos de las entrevistadas. La metodología adoptada fue de naturaleza cuali-cuantitativa con enfoque en las representaciones sociales sobre la experiencia de la enfermedad. Para el análisis de las entrevistas fue utilizado el instrumento “discurso del sujeto colectivo”. Se observó la presencia de la creencia popular sobre los cuidados con el cordón umbilical y la deficiencia de los servicios en el proceso de la educación para la salud. Es urgente programar esfuerzos estratégicos específicos, dirigidos hacia la capacitación de parteras y profesionales de la salud, incrementar servicios de prenatal y ampliar la cobertura de vacunación, principalmente, en las regiones de donde provienen los casos de la investigación, contribuyendo asi para la eliminación de la enfermedad.

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

    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 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 ABSTRACT: Visceral Leishmaniasis by Leishmania infantum chagasi is an endemic zoonosis present in many areas of Brazil. This parasite needs reservoirs for maintenance of the infection and the presence of dogs in urban areas is a key factor for the spread of canine visceral leishmaniasis (CVL. The aim of this study was to report the first autochthonous case of CVL in the municipality of Iguatama, in west central region of Minas Gerais State. Dog infection by Leishmania infantum chagasi was confirmed in the municipality, previously considered as non-endemic area to CVL. The canine infection by Leishmania was confirmed by three immunological tests for antibodies: indirect immunofluorescence assay (IFA, rapid Dual Path Platform (DPP® CVL immunochromatographic test, enzyme-linked immunosorbent assay (ELISA, and microscopic demonstration of Leishmania amastigotes in imprints of spleen and bone marrow stained by Giemsa. The species Leishmania infantum chagasi was confirmed by molecular diagnosis (PCR. Studies are being carried out, aiming to describe the importance and the prevalence of this disease in the region and factors associated with its transmission.

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

    Connecting (small) family farmers to the emerging biodiesel industry requires careful design of the institutional arrangements between the producers of oil crops and the processing companies. According to institutional economics theory, the design of effective and efficient arrangements depends on production and transaction characteristics, the institutional environment, and the organizational environment supporting the transaction between producers and the industry. This paper presents a comparative study on two cases in the feedstock-for-biodiesel industry in the state of Minas Gerais, Brazil. The two case studies represent the production and transaction system of soybeans (Glycine max L. Merrill) and castor beans (Ricinus communis L.). Important elements of effective and efficient institutional arrangements are farmer collective action, availability of technical and financial support, and farmer experience with particular crops. - Highlights: ► We study institutional arrangements for feedstock transactions between family farmers and the biodiesel industry. ► We focussed on soybean and castor bean production and transaction systems. ► Institutional arrangements are affected by product and production characteristics. ► They are also affected by collective actions organizations such as cooperatives. ► Soybean involves lower transaction costs and therefore more simple arrangement than castor bean.

    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 more advanced lesion stages and their intensity were used to calculate the gross sum, which aided in decision-making for chemical control. One collected data on production and firmness, pH, and acidity analysis of fruits. For the GS 2,500 treatment, taking into account 2-year evaluation, there was a reduction from 12 to 3 applications, i.e. 75% less fungicide was applied, without loss in productivity. Therefore, one suggests, taking into account the conditions of Nova Porteirinha, the application of BFS for chemical control of Yellow Sigatoka, using the GS value of 2,500 as an indicator of the correct time to perform pulverization.

    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.

    Homeopathy is a therapeutic system that uses small doses of substances to stimulate autoregulatory and self-healing processes. The aim of this study was to investigate the prevalence of the use of homeopathy by the population of Montes Claros, Brazil, and the socioeconomic profile of users. Probabilistic cross-sectional study with cluster sampling, in the city of Montes Claros, Minas Gerais. This study was conducted by applying semi-structured questionnaires. The sample was composed of 3,080 people. For the statistical analysis, Student's t test and the chi-square test were used. The statistical significance level used was P use of homeopathy was 2.4%. The factors associated with its use were female gender, schooling and income. The main reason that led to seeking homeopathy was "Conventional treatment did not have any effect". For 70.2% of the users, the cost of the treatment was considered reasonable or cheap. About 73% were satisfied or very satisfied with the treatment received through homeopathy. The prevalence of the use of homeopathy found here was less than that reported in other countries. People with higher income and schooling levels used homeopathy more frequently. There was higher prevalence among women. Most users declared themselves satisfied with the treatment received.

    Austenitic steel multi-pass welds exhibit a heterogeneous and anisotropic structure that causes difficulties in the ultrasonic testing. Increasing the material knowledge is a long term research field for LCND laboratory and EDF Les Renardières in France. A specific model has been developed: the MINA model (Modelling an Isotropy from Notebook of Arc welding). Welded material is described in 2D for flat position arc welding with shielded electrode (SMAW) at a functional scale for UT modeling. The grain growth is the result of three physical phenomena: epitaxial growth, influence of temperature gradient, and competition between the grains. The model uses phenomenological rules to combine these three phenomena. A limited number of parameters is used to make the modelling possible from the information written down in a notebook of arc welding. We present all these principles with 10 years' hindsight. To illustrate the model's use, we present conclusions obtained with two recent applications. In conclusion we give also insights on other research topics around this model : inverse problem using a F.E.M. code simulating the ultrasonic propagation, in position welding, 3D prospects, GTAW.

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

    The northeast region of Minas Gerais and South Bahia are centered to the east of 42 0 00 ' WGr, between parallels 15 0 and 18 0 . Its tectonic-thermal evolution is presented here with the support of stratigraphy/lithology, structural analysis, petrography, petrochemistry, regional metamorphism/retro metamorphism and radio chronology. It is pointed out that the evolution occurred in a mobile belt initiating its history in the terminal Archean up to Inferior Proterozoic. The northeast of the region attained crustal stability during 1700 My up to 1800 My (Sao Francisco Craton) meanwhile the rest of the zone kept mobilized till upper proterozoic times. Radio chronological studies suggest for the post tectonic granitic rocks, ages from the brasiliano cycle as well as for those pre-existing rocks which suffered isotopic regeneration and metamorphose in that same cycle an original age from Archean to inferior proterozoic times, except for those which are situated in the northeast part of the region. Petrochemical data point to an origin from sedimentary processes for the majority of the metamorphosed rocks in this region. (author)

    This retrospective study in Belo Horizonte, Minas Gerais, Brazil, aimed to provide indicators on the sale and consumption of anorexigenic substances. During the first stage, 2,906 of 168,237 prescriptions received by pharmacies in 2003 were analyzed, showing low quality of prescriptions. Projected consumption in defined daily doses was 19.75 DDD/1,000 inhabitants/day in 2003. Fenproporex (59.8%) was the most widely consumed drug. One pharmacy was responsible for 39.8% of the pharmaceutical sales. During the second stage, 14,554 sales records from this "blockbuster" pharmacy were analyzed, from April to August 2005; 9.2% of sales were for anorexigenic products, 91.8% of which prescribed in association with another substance. The data suggest irrational use of anorexigenic drugs by these consumers and highlight the need for proper regulation of these products. It is important to understand both the role of pharmacies in this regulation and that of physicians in the rational use of these substances.

    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 ABSTRACT: In a rural property of the Midwestern Minas Gerais, Brazil, three 2.5 to 3-year-old female bovines (7/8 Holstein x 1/8 Gir weighing approximately 380kg died after showing brownish colored mucosa of conjunctiva and vaginal vestibule, gray-bluish tongue, dyspnea, sialorrhea, tympany, and progression to sternal decubitus and death. In the macroscopic evaluation of one of the bovines, dark (chocolate-colored blood of difficult coagulation, and intensely cherry-red skeletal and cardiac musculature were observed. Beyond that were observed brownish lungs, kidneys, liver, and encephalon, and all the stomach compartments were dilated due to large amounts of gas. In addition, the carcass exhaled a nitrous odor. The diphenylamine test and the nitrate dosage in the forage (Pennisetum purpureum, “elephant grass”, Napier grass cultivar used in feeding the bovines showed a high concentration of nitrate, allowing the diagnosis of nitrate/nitrite intoxication. The main factors leading to the poisoning were attributed to excessive fertilization of grass with bovine manure, the occurrence of a drought period followed by a rainy season, lack of adaptation of the bovines to a nitrate-rich diet, and a diet composed almost exclusively of elephant grass. This is the first report of spontaneous nitrate/nitrite poisoning in cattle in southeastern Brazil.

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

    Full Text Available Milk pasteurization is a critical issue in the dairy industry, and failures in this process can affect final product safety. Scharer's enzymatic method is still traditionally used to verify pasteurization efficiency compliance, and it is based on screening for residual alkaline phosphatase in milk. Although several methods are used to quantify enzymatic activity to assess milk pasteurization efficiency, there is a small amount of published data regarding the use of these methods to quantify alkaline phosphatase in cheese. In this study, the Scharer's modified method was used to determine the levels of residual alkaline phosphatase in standard minas cheese, before and after 20 days of ripening. The cheeses were made using raw or pasteurized milk with the addition of different concentrations of raw milk (0; 0.05%; 0.10%; 0.20%; and 0.50%. In the fresh cheese samples, the method showed a sensitivity of only 0.50% with the addition of raw milk to the pasteurized milk used to make cheese. In addition, levels of up 0.20% of raw milk in pasteurized milk, the concentrations of phenol was inferior to 1μg phenol/g of dairy product which is the preconized indicator value for adequate pasteurization.

  13. Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil

    Luiza F. A. de Paula

    Full Text Available ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. They are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that differ from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. This study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families, of which six were new to science. The richest family was Bromeliaceae (10 spp., followed by Cyperaceae (seven spp., Orchidaceae and Poaceae (six spp. each. Life forms were distributed in different proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that floristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil.

    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 This work aimed to present a partial diagnosis of street tree under power grid in five cities in the West Region of Minas Gerais, which had more power outages because of conflicts with trees. We identified 186 trees, belonging to 17 species of exotic origin and 30 species of native origin. The most frequent species were Poincianella pluviosa (30.43%, Ligustrum lucidum (10.86%, Michelia champaca (6.52% and Schinus molle (4.89%, which together amounted to 52.7% of the assessed trees. Most trees (84.78% were located in streets wider than 7 m, and 36.55% of the trees were planted in sidewalks with a minimum of 2 m wide. Those trees present ther first bifurcation at over 1.80 m above ground level. The pruning performed due to conflicts with the grid amounted 40.22%. Trees with height equal or over 6 m represents 72.83% of the sampled population. It was observed that there is not an appropriate management plan of urban trees under the grid, as the trees frequency is concentrate on few species that were mostly medium and large size.

    Nara Tadini Junqueira

    Full Text Available The rio das Velhas, located in central Minas Gerais State (Brazil, is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two dimensions of the PCA suggest that the morphological volume occupied by the headwaters region is smaller than the other sections, because of the low richness of the site. However, morphological hypervolumes of the four reaches analyzed by Euclidean distances were not statistically different. The results indicated that only the density of morphological types increases along the rio das Velhas, and there is no difference between the headwaters and upper courses. Therefore, in order to use functional groups related to the morphology of the species as tools to take measures for the conservation and revitalization of the rio das Velhas, it is necessary analyze the density of species within these groups, as well as their composition.

    In recent years, a new pattern of schistosomiasis transmission has been described which is related to recreational activities associated with rural or ecological tourism and migratory flows and accompanying changes in social dynamics in Brazil. The objective of this report is to describe two schistosomiasis outbreaks that occurred during the practice of rural tourism in Minas Gerais, Brazil, and review this pattern of transmission within the wider context of schistosomiasis control. The first outbreak was characterized by its high infection rate, showing that 59 % of the exposed eco-tourists became positive for infection with Schistosoma mansoni . In addition, all three disease transmitting species of intermediate host snails were found in the area. In the second outbreak, all members of one tourist family were infected and reported contact with water in a well-known tourist area. The malacological survey in the region revealed an infection rate with S. mansoni of 8.3 % among the collected snails. Infection of urban dwellers that report contact with contaminated water associated with ecotourism represents a new pattern of disease transmission and dissemination. The infection with the disease at these occasions finds its expression in outbreaks of acute schistosomiasis among internal tourists to rural areas. Therefore, epidemiological surveillance in endemic areas should be aware of this schistosomiasis transmission pattern, and a multidisciplinary approach, most of all sanitation and health education measures, is required in order increase the efficiency of control strategies.

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

    2010-07-01

    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 Neste artigo passa-se em revista a história da conquista e ocupação das terras do vale do São Francisco, cuja trama há quase um século adquiriu sua versão definitiva na historiografia tradicional, em vários capítulos a respeito a da "expansão geográfica", como em Basílio de Magalhães; ou b da "história territorial", por Felisbelo Freire; ou c dos "caminhos antigos e povoamento do Brasil", como em Capistrano de Abreu, autor que, se não o primeiro, sem dúvida foi o que mais influiu na tessitura do enredo. Aqui, contudo, os objetivos são distintos, apesar de suas fontes arquivísticas permanecerem inescapavelmente as mesmas. Parte-se do pressuposto de que, na segunda metade do século XVII, encerrou-se o processo de conquista do território às tribos indígenas estabelecidas na margem direita do alto-médio São Francisco. Sob esta perspectiva, ao invés de repetir, mais uma vez, a história das expedições ao interior do Brasil, o que aqui se busca é encontrar o lugar que estas expedições ocuparam nesse processo de conquista e ocupação territorial, que logo em seguida tornaram possível a articulação, tanto da costa com os sertões, quanto dos diferentes sertões entre si.This article aims at reviewing the history of the conquest and occupation of the San Francisco river valley, in Minas Gerais. The definite version of which was established more than a century ago, in several chapters concerning a the geographical expansion, as named by Basílio de Magalhaes; or b the territorial history, by Felisbelo Freire; or c the ancient routes and settlement of Brazil, as in Capistrano de Abreu. Here, meanwhile, the objectives are quite different, despite their archival sources be inescapably the same. It is assumed that in the second half of the sixteenth century the process of conquest of the territories occupied by indian tribes settled in the right bank of the San Francisco river had come to an end.

    Full Text Available The objective of this work was to evaluate the effects of using bulk milk with different somatic cell counts (SCC on the quality of minas frescal cheese. A randomized complete block design was used, with 3x5 factorial treatments, with three SCC levels (low, 125,000 cells mL-1; intermediate, 437,000 cells mL-1; and high, 1,053,000 cells mL-1 and five storage durations. Cheese was vacuum-packed in plastic bags and analyzed after 2, 9, 16, 23 and 30 days of storage at 4ºC. Somatic cell counts did not affect dry matter, fat, ash content, pH, free fatty acid concentrations and sensory parameters of minas frescal cheese. However, SCC in milk increased losses of protein in whey and decreased the cheese protein content. These changes did not affect the moisture-adjusted cheese yield and proteolysis during 30 days of storage. An interaction effect between SCC and time of storage was observed for firmness and sensory grades of cheeses. Results indicated that raw milk used to produce minas frescal cheese should not contain high SCC, in order to avoid lower acceptance of the product after 30 days of storage.O objetivo deste trabalho foi avaliar o efeito do uso de leite com diferentes contagens de células somáticas (CCS, na qualidade do queijo minas frescal.

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

    Full Text Available 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 Resumo Tambor de Mina é o nome da religião afro-brasileira no Maranhão e na Amazônia estabelecida a partir de São Luís desde meados do século XIX. Existem duas casas fundadas por africanos que se continuam: a Casa das Minas Jeje, de origem daomeana e a Casa de Nagô, iorubana de onde derivam a maioria dos terreiros de Mina recentes e atuantes. Trata-se de religião muito ritualizada e discreta, envolvida em segredos e mistérios cuja mitologia é pouco comentada e os rituais muito desenvolvidos. As religiões afro-brasileiras se caracterizam pela realização de festas com transe, danças e comidas que atraem muitos participantes. A comida é bastante para oferecer a todos e distribuir as sobras. A fartura nas festas maiores constitui um dos elementos de prestígio das casas. O texto baseia-se em entrevistas com líderes de um terreiro antigo e de duas casas recentes, sobre comida de santo nas festas. Na linguagem de Mauss o sacrifício constitui obrigação que estabelece uma comunicação entre o mundo sagrado e o profano. O preparo e o consumo da comida de santo permitem conhecer aspectos do sincretismo e dos simbolismos nos rituais. Palavras-chave: Religiões afro-brasileiras; comida de santo; sincretismo; festas; ritual.   Abstract Tambor de Mina is the name of the Afro-Brazilian religion in Maranhão and Amazon established in São Luís (capital of Maranhão state since the mid-nineteenth century.

    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)

    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 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

    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

  16. A structural analysis of the Minas da Panasqueira vein network and related fracture generations

    2014-05-01

    The Minas da Panasqueira is a world-class W-Cu-Sn vein-type deposit, situated within the Central Iberian Zone of the Palaeozoic Iberian Massif (Portugal). The deposit consists of a network of subhorizontal, sill-like massive quartz veins situated above the southwestern extremity of a greisen cupola, within regionally metamorphosed, isoclinally folded, lower-greenschist slates and greywackes. The greisen cupola is part of a larger intrusive complex, emplaced during the late- to post-tectonic stage of the Variscan orogeny. The late-Variscan granitoid(s) underlying the Panasqueira deposit is considered to have served as a major metal source. The structure of the network of subhorizontal extension veins, consists of numerous planar vein lobes that are separated by host-rock bridges and merge at branch-points. A structural analysis demonstrates that not only within the Panasqueira mine, but also on a more regional scale, one or more generations of flat-lying fractures are present. The veins clearly exploited these pre-existing discontinuities, as confirmed by (1) the vein geometry being directly influenced by variations in the orientation of the initial fracture sets and (2) the geometry of the rock bridges and overlapping vein morphologies, consistently showing straight-line propagating crack tips. If veining is governed by a preferential, strongly developed anisotropy in the host rock, the hypothesis of vein lobes and rock bridges forming during propagation of the parent crack by tip-line bifurcation and confinement processes (Foxford et al., 2000) does not seem plausible. Instead, we propose that the rock bridges formed from several, initially separate and small veinlets that eventually overlapped in an en echelon arrangement during progressive propagation and inflation. Bending of the rock bridges and incipient vein rotation indicate that veining occurred near the brittle-ductile transition. Using a quantitative analysis of bridge orientations, vein aspect ratios

    Full Text Available The rio das Velhas, located in central Minas Gerais State (Brazil, is a major tributary of the rio São Francisco. Despite several anthropogenic pressures, this basin supports more than 115 fish species. The aim of this study was to compare the morphological space occupied by fish assemblages in four regions (headwaters, upper, middle, and lower course along the channel of the rio das Velhas. We try to answer the following question: Is there a change in the morphological organization of the fish along the longitudinal gradient of the river? Individuals from 67 species, collected at several sites in the basin from 1999 to 2008, were measured for 11 morphological attributes related to swimming behavior and habitat use. Through the graphs, the first two dimensions of the PCA suggest that the morphological volume occupied by the headwaters region is smaller than the other sections, because of the low richness of the site. However, morphological hypervolumes of the four reaches analyzed by Euclidean distances were not statistically different. The results indicated that only the density of morphological types increases along the rio das Velhas, and there is no difference between the headwaters and upper courses. Therefore, in order to use functional groups related to the morphology of the species as tools to take measures for the conservation and revitalization of the rio das Velhas, it is necessary analyze the density of species within these groups, as well as their composition.O rio das Velhas, localizado na região central do estado de Minas Gerais (Brasil, é o mais extenso tributário do rio São Francisco. Apesar dos inúmeros impactos antrópicos que sofre, sua bacia abriga uma rica ictiofauna, com mais de 115 espécies conhecidas. O objetivo deste estudo foi comparar o espaço morfológico ocupado pelas assembleias de peixes em quatro regiões (cabeceira, alto curso, médio curso e baixo curso ao longo da calha do rio das Velhas.

    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 Geomorphological mapping allows the evaluation of geoheritage and subsidizes geoconservation efforts. This work aimed at identifying and analyzing the landforms at the Minas do Camaquã Geosite Protection Area (MCGPA – Rio Grande do Sul state – Brazil, emphasizing the anthropogenic morphologies to subsidize the conservation of the studied area’s geomorphological heritage. A geomorphological map (2015 of the MCGPA was made (1:25.000 to recognize and identify the natural and anthropogenic landforms. Based on this map, four sectors were identified according to the representativeness of the landforms: (1 Mineral extraction sector; (2 Tailings deposition sector; (3 Structural features sector; and (4 Boundary sector. The mining activities were the main reason for the geomorphological alterations and the creation of anthropogenic morphologies in the site. Despite the significant disturbance caused by the mining activity, there are still features of geologic-geomorphological interest fairly preserved. The identified and analyzed anthropogenic morphologies can describe the history of the mining activities that took place in the area and which formed a set of landforms currently present in the MCGPA. Although the surface features are not originated from natural morphogenesis, they belong to the area’s geodiversity. Furthermore, considering these features as geoheritage would create the need for management aiming at avoiding the collapse and degradation of these forms. Nowadays, the mining activities have remained inactive, and this set of anthropogenic morphologies need to be understood under a geomorphological point of view which will allow future exploitation of its potential touristic, scientific, pedagogical and cultural uses. The best way to promote and develop strategies of geoconservation for this place is to create and foment geotourism in this area.

    Groundwater is the largest reservoir of fresh water on Earth and the depletion of aquifer systems is a reality, both in semi-arid and humid regions. The hydrology of watersheds is a field of study that is concerned with the movement of waters from the rains and its physical-chemical changes. Groundwater resources in these regions are a sensitive issue, requiring careful management to avoid quality degradation. The present study focuses the groundwater system at the interface of the Pandeiros and Peruaçu river basins in the northwest region of Minas Gerais State. The methods used were the evaluations of the hydrochemistry, as well as isotopic, and physicochemical parameters, allied to geological studies to investigate surface and groundwater, their possible interactions and spatial distribution. The hydrochemical results correlated with the physicochemical measurements show water contrasts in the study area, which is geologically composed from bottom to top by gneisses and granites (Januaria Complex), limestone and siltstones (Bambuí Group), sandstones and eluvial sediments (Urucuia Group), eluvio-coluvial cover and alluvial deposits. It has been observed that waters in the context of sandstones and siliceous sediments are sodium bicarbonate waters, slightly acidic pH and low in TDS, whereas waters in pedological / geologic context of limestones are calcium bicarbonate waters exhibiting basic pH and high TDS. The deuterium (D) and oxygen-18 signatures of the groundwater are compared to the global meteoric water line (GMWL). The average values of the isotopes in the study area are slightly variable, indicating that the isotopic signatures are related to rainfall precipitation. It has been possible to suggest an evaporation line pattern starting from the position of springs, passing though streams and finally ending in the lagoon. The local evaporation line can be represented by the equation δD = 5,8 δ{sup 18}O - 2,4. (author)

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

The studied here is related to the function of the mine, which possessed important polisemic values. Not only it is used for stablishing a belie religious or a reat loving environement but also to use this motif with the metaphoric value of passion or as a true laberinto of love, includying trascendental mitological symbols. Everything together is aimed to create a very fast and mysterious activity mixing both comic and tragic effects in which the nonexpected becomes not only dramatical essence but also a personal experience about destinity and life.Calderón utiliza varios recursos escénicos para establecer determinadas situaciones dramáticas en sus obras. El que se estudia aquí se refiere a la función de la mina, que posee valores polisémicos muy notables, los cuales van desde los que le sirven para establecer un ámbito guerrero, religioso, amoroso de carácter real, hasta la utilización de este motivo con carácter metafórico de la pasión amorosa o como verdadero laberinto de amor que incluye incluso una mitologización trascendente de la misma. Todo ello le sirve para configurar en sus obras una acción trepidante, misteriosa, en la que se mezcla lo cómico con lo trágico, y en donde lo inesperado cobra un valor no sólo de esencia dramática sino también de vivencia existencial acerca del destino de la vida.

    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.

    On April 27, 1986, about 75,000 to 100,000 barrels of medium-weight crude oil spilled into the Caribbean Sea from a refinery in Bahia Las Minas, Panama. After weathering for 13 days in warm, sunny conditions, the oil reached the intertidal reef flat and biological reserve at Punta Galeta, which had been under study since the early 1970's. The prespill data base consisted of detailed, time-series monitoring of sessile biota on the reef flat in relation to changes in sea and weather conditions. To assess the effects of the oil, this monitoring was expanded to other sites and continued after the oil spill. Within the resolution of our measurements, most detectable mortality of the sessile biota occurred in specific zones of the reef flats where factors such as winds, waves, water levels, and topography caused the oil to accumulate. Where the oil floated over the reef flats without prolonged accumulation, little mortality was recorded. The sessile biota regenerated from fragments surviving in place or washing in from nearby habitats, and the regeneration times ranged from less than one year to more than five years. For the sessile biota, there appeared to be no recolonization via planktonic larvae or spores. The fastest regeneration times were for species that propagated from fragments that survived in place; the slowest were for species that suffered nearly 100 percent mortality and recolonized from fragments washing in from subtidal habitats. Because regeneration of sessile species on tropical reef flats depends on regrowth from local survivors, control and cleanup of oil spills in these environments should be designed to maximize the survival of resident populations

    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

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

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

    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.

    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 production of this cheese includes the salting, by offering important functions for this product. The salting is performed by adding sodium chloride (NaCl, however in excess this salt may be harmful to consumer health. Then, it was evaluated the development of tree formulations of Minas fresh cheese sheep’s milk (100% NaCl – QA; 75% NaCl and 25% potassium chloride (KCl – QB; 50% NaCl and 50% KCl – QC and they were evaluated by physical-chemical, microbiological and sensorial analyzes. A partial replacement of NaCl by KCl did not influence the moisture, protein and ash contents, pH and water activity of the cheeses. Furthermore, a 50% substitution of NaCl by KCl enabled to obtain a cheese with reduced sodium content in relation to the standard with 100% NaCl. The sensorial analysis showed that the substitution of 50% (QC and 25% (QB of NaCl by KCl did not show significant for the overall acceptance index, however, the use of KCl was perceived by the evaluators, since the formulations QB and QC differed significantly from the standard (QA. However, in the multiple comparison test there was no significant difference between the samples. Thus, the results indicated that a partial replacement of NaCl by KCl can be performed at Minas fresh cheese from sheep’smilk.

    While performing the Hajj, hajjis face different risks related to the environment, their behaviors and their health conditions that can result in a variety of diseases. The objective of this study was to determine the pattern of diseases among pilgrims seeking medical services in Mina primary health care centers (PHCCs) during the Hajj season in 1429 (2008). This is a descriptive study based on the medical records of a random sample of 4136 patients who attended 13 randomly selected Mina PHCCs from 8 to 12 Dhu-Alhijja, 1429 H (6-10 December 2008). The majority of the patients were men (70.7%), and most of the patients were between 45 and 64 years of age (42.8%). One-fifth (20.2%) of the patients suffered from multiple diseases. Respiratory diseases were the most common (60.8%), followed by musculoskeletal (17.6%), skin (15.0%) and gastrointestinal (13.1%) diseases. Diabetes, asthma and hypertension each constituted less than 3% of the total diseases. Respiratory diseases were the most common independent of nationality or the day of visit, while the frequency of the other diseases varied according to nationality and the day of visit. The most frequently prescribed drugs were analgesics, antipyretics, antibiotics and cough syrups. This study describes the pattern of diseases among pilgrims attending Mina PHCCs, which may aid in providing the best possible health care services to pilgrims.

    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 Lanthanum modified lead titanate ferroelectric thin films with a composition Pb0.7La0.2TiO3 have been prepared by a diol based sol-gel technique. The effect on the film structure, microstructure and composition of the initial PbO content, from the nominal value to an excess of 20 mole%, and of the heating rate of the thermal treatment of crystallisation at 650ºC, from 10ºC min-1 to more than 500ºC min-1, has been studied. It is not possible to obtain single phase films with the treatment at 10ºC min-1, even when PbO volatilisation is compensated with an initial excess of PbO of 20 mole%. It is possible with the treatment at more than 500ºC min-1 and the latter excess of PbO. These films present a relative dielectric permittivity at room temperature of ε= 700, and a variation between room temperature and 100ºC of Δε = 75, being both parameters very interesting for DRAMs.

    Se han preparado láminas delgadas ferroeléctricas de titanato de Pb modificado con un 20% de La, Pb0.7La0.2TiO3, por una técnica sol-gel basada en la ruta de los dioles. Se ha variado el contenido inicial de PbO, del nominal a un exceso del 20% molar; y la velocidad de calentamiento en el tratamiento térmico de cristalización a 650ºC, de 10ºC min-1 a más de 500ºC min-1, y estudiado su efecto en la microestructura, estructura y composición de las láminas. No es posible obtener láminas monofásicas con el tratamiento con 10oC min-1, aun compensando la volatilización de PbO con un exceso inicial del 20% molar. Sí lo es con tratamiento rápido manteniendo dicho exceso de PbO. Estas últimas láminas presentan una permitividad dieléctrica a temperatura ambiente de ε=700, y una variación entre ambiente y 100ºC de Δε= 75, parámetros muy interesantes para memorias DRAMs.

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

The objective of this work was developing Minas-type fresh cheese with probiotic properties from buffalo milk. Four batches of Minas-type fresh cheese were prepared using buffalo milk: batch T1 in which neither culture nor lactic acid added; batch T3 in which only lactic acid added; batches T2 and T4 , both added of Lactobacillus acidophilus LAC 4, but T4 was also acidified. Resulting cheeses were evaluated for probiotic culture stability, texture profile, sensory acceptance, and changes in pH. The T4 probiotic cheese presented hardness, gumminess, and chewiness significantly lower than the other treatments. However, values for springiness and cohesiveness did not differ between all cheeses, and no sensory differences (p > 0.05 were found between treatments for texture, taste, and overall acceptance. The addition of probiotic to the acidified cheese (T4 yielded best aroma. The populations of L. acidophilus were greater than 10(6 CFU g-1 after 28 days of storage all products.

Para realizar a análise, utilizamos como referência uma documentação censitária que tentou contabilizar a população de todos os distritos mineiros e registrou as crianças que estavam nas escolas. A partir do registro censitário, construímos um perfil racial das escolas, confrontando-o com informações fornecidas por outros documentos (listas de professores, relatos de viajantes, memórias que revelaram uma presença majoritária dos negros nas escolas de instrução elementar. A interpretação que produzimos em relação à presença dos negros nas escolas mineira indica que essa instituição era um dos elementos acionados por esse grupo com objetivo de afirmação no espaço social. Em relação a isso, destaca-se o fato de que a escolarização adquiriu significados específicos em meio à população negra, ou seja, representava a sua inserção na cultura letrada, mas também uma forma de demarcar um distanciamento do mundo da escravidão e uma demonstração de domínio dos códigos de conduta das pessoas livres.The period between 1820 and 1850 marks the beginning of the construction and structuring of a public education policy that aimed at educating the people of the province of Minas Gerais.

    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 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.

    Drought is endemic to the North American Great Plains, causing severe economic consequences. However, instrumental climate data only exist from ca AD 1890, and limited tree-ring, paleolimnological, archeological and eolian records document the last two millennia. To address this lack of monitoring and paleoclimatic data, the pollen preserved in the varved sediments of Lake Mina, Minnesota, on the northeastern border of the Great Plains, were analyzed. May and February mean monthly temperatures and "annual precipitation minus potential evapotranspiration" were reconstructed at a 4-year resolution using a pre-settlement pollen-climate calibration set. The period of the so-called Little Ice Age (LIA) (AD 1500-1870) was colder than the Medieval Climate Anomaly (MCA) (AD 1100-1500) in west-central Minnesota. Winter temperatures in the LIA declined more than summer ones. The pollen record suggests that the LIA occurred in three phases: an initial cold phase from AD 1505 to AD 1575, a warmer phase, and then a very cold phase from AD 1625 to AD 1775. There were severe droughts detected in the Lake Mina record from AD 1660 to AD 1710 and AD 1300 to AD 1400, suggesting that high-resolution pollen records can detect events previously defined from the tree-ring records. This latter century-scale drought is concurrent with the widely reported "AD 1250-1400 mega-drought", which exceeds the severity of 20th century droughts.

    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.

The range of available laboratory tests was limited, what demanded the services of supporting laboratories. None of the evaluated laboratories developed any systematic activity on quality management, including control of analytical quality, maintenance of laboratory equipment, calibration and performance evaluation of critical equipment, continuing education programs, and safety and biosecurity.Conclusion: The effective role of laboratory test results in medical decision is unquestionably impaired, risking the safety of SUS patients. The present work reveals the deficiencies of public laboratory services in Minas Gerais, and proposes a new management model, which is able to associate operational quality, technological development and optimization of human and material resources with higher productivity.

    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.

    Full Text Available ABSTRACT: Cysticercosis is caused by Taenia solium, a parasitic zoonosis that affects human and pigs raised free-range in developing countries. The epidemiology of the taeniosis cysticercosis complex in Brazil is poorly understood especially when it comes to field research. The aim of this study was to estimate the prevalence and identify the risk factors associated with porcine cysticercosis in rural communities located in the east of Minas Gerais (MG, Brazil. From 371 farms in the county of Tumiritinga/MG, 101 farms from 14 communities were randomly sampled. Blood samples from pigs were collected, and epidemiological questionnaires were carried out. The serum samples obtained were analyzed through immunodiagnosis techniques, including ELISA and Western Blot, both for the detection of antibodies. The data obtained by different surveys were analyzed using EpiInfo 3.5.1 software to determine seroprevalence and risk factors associated with cysticercosis. The prevalence of farms with porcine cysticercosis was 9.9% (10/101 and antibody-based seropositive was 5.3% (13/247. The results indicate that cysticercosis occurs in high level in the rural area never studied before. These results suggest the presence of tapeworm carriers contributing to the occurrence and maintenance of this zoonotic life cycle in the county. Regarding risk factors, the most significant determinants for porcine cysticercosis in the field were free-range pig management (OR: 17.4, p: 0.0001, the method of disposal of human faeces in the environmental (OR: 7.6; p 0.012, and the size of the farm. Porcine cysticercosis was diagnosed only in areas represented by Agrarian Reform Settlements. From the results, it is possible to recommend as a means of control and prevention the destination of human faeces in appropriate sanitary landfills and the production of pigs in an enclosed area. Additionally, improving education in the communities sampled will indirectly affect the spreading of

    Full Text Available ABSTRACT BACKGROUND: The term dangerous universal blood donor refers to potential agglutination of the erythrocytes of non-O recipients due to plasma of an O blood group donor, which contains high titers of anti-A and/or anti-B hemagglutinins. Thus, prior titration of anti-A and anti-B hemagglutinins is recommended to prevent transfusion reactions. OBJECTIVE: The aim of this study was to estimate the frequency of dangerous universal donors in the blood bank of Belo Horizonte (Fundação Central de Imuno-Hematologia - Fundação Hemominas - Minas Gerais by determining the titers of anti-A and anti-B hemagglutinins in O blood group donors. METHOD: A total of 400 O blood group donors were randomly selected, from March 2014 to January 2015. The titers of anti-A and anti-B hemagglutinins (IgM and IgG classes were obtained using the tube titration technique. Dangerous donors were those whose titers of anti-A or anti-B IgM were ≥128 and/or the titers of anti-A or anti-B IgG were ≥256. Donors were characterized according to gender, age and ethnicity. The hemagglutinins were characterized by specificity (anti-A and anti-B and antibody class (IgG and IgM. RESULTS: Almost one-third (30.5% of the O blood group donors were universal dangerous. The frequency among women was higher than that of men (p-value = 0.019; odds ratio: 1.66; 95% confidence interval: 1.08-2.56 and among young donors (18-29 years old it was higher than for donors between 49 and 59 years old (p-value = 0.015; odds ratio: 3.05; 95% confidence interval: 1.22-7.69. There was no significant association between dangerous universal donors and ethnicity, agglutinin specificity or antibody class. CONCLUSION: Especially platelet concentrates obtained by apheresis (that contain a substantial volume of plasma, coming from dangerous universal donors should be transfused in isogroup recipients whenever possible in order to prevent the occurrence of transfusion reactions.

    During the spring and summer of 2006 University of Kansas geophysics students and faculty acquired shallow, high resolution seismic reflection data over actively deforming alluvial fans developing across the Emmigrant Peak (in Fish Lake Valley) and Queen Valley Faults in western Nevada. These normal faults represent a portion of the transition from the right-lateral deformation associated with the Walker Lane/Eastern California Shear Zone to the normal and left-lateral faulting of the Mina Deflection. Data were gathered over areas of recent high resolution geological mapping and limited trenching by KU students. An extensive GPR data grid was also acquired. The GPR results are reported in Christie, et al., 2006. The seismic data gathered in the spring included both walkaway tests and a short CMP test line. These data indicated that a very near-surface P-wave to S-wave conversion was taking place and that very high quality S-wave reflections were probably dominating shot records to over one second in time. CMP lines acquired during the summer utilized a 144 channel networked Geode system, single 28 hz geophones, and a 30.06 downhole rifle source. Receiver spacing was 0.5 m, source spacing 1.0m and CMP bin spacings were 0.25m for all lines. Surveying was performed using an RTK system which was also used to develop a concurrent high resolution DEM. A dip line of over 400m and a strike line over 100m in length were shot across the active fan scarp in Fish Lake Valley. Data processing is still underway. However, preliminary interpretation of common-offset gathers and brute stacks indicates very complex faulting and detailed stratigraphic information to depths of over 125m. Depth of information was actually limited by the 1024ms recording time. Several west-dipping normal faults downstep towards the basin. East-dipping antithetic normal faulting is extensive. Several distinctive stratigraphic packages are bound by the faults and apparent unconformitites. A CMP dip line

    The Brazilian uranium mine of Caldas, Minas Gerais, has produced 1,030 tons of uranium, during twenty years of operation, from 1977 to 1997. Actually, the mine and the mill are deactivated and the decommissioning process is in course. The total mass of ore tailings produced is equal to 108,164,248 tons and the mass of milling solid waste is equal to 2,395,821 tons. The ore tailings are distributed through several piles placed near the mine pit and the milling wastes are deposited in the waste dam. The mine pit and two of the tailing piles generate acid water which requires treatment before the environmental standards are achieved and the water is liberated to the environment. The waste dam also liberates treated water to the environment. This work presents data, discussions and main conclusions of radiological monitoring of the water liberated by Caldas uranium mine to the environment during the 2013. The complete annual environmental monitoring program requires 1,689 surface water samples; 39 underground water samples; 17 sediment samples; 5 soil samples; 7 farm products and fish samples; and 1,728 direct measurements of pH, temperature, dissolved oxygen, turbidity and salinity. The chemical parameters determined in water samples are: Mg"2"+, Ca"2"+, Cr"n"+, Cun"+, Ni"2"+, Zn"2"+, Ba"2"+, Mn"n"+, Fe"n"+, Al"3"+, SiO_2, SO_4"2"-, F-, Na"+, K"+, P, Cl"-, NO_3"2"-, and N. The radionuclides determined in all samples are: U-238, Th- 230, Ra-226, Pb-210, Th-232 and Ra-228. All of the Caldas uranium mine environmental monitoring results will be presented in the INB annual report of the year 2013. The maximum permissible concentrations of radionuclides in the liquid effluents were determined considering the maximum annual dose constraint of the optimization process for members of the public, which is equal to 0.3 mSv per year. According to the monitoring results of year 2013, the increase in the annual dose of the individual of the critical group is approximately equal to

    Full Text Available Na macroconfiguração geomorfológica do sudeste de Minas Gerais é notória a organização dos planaltos, em planta e perfil, segundo degraus escalonados. A delimitação espacial desses degraus coincide com a organização da rede hidrográfica regional, composta por grandes bacias interiores (Paraná e São Francisco e por bacias costeiras menores (Doce e Paraíba do Sul. Esses agrupamentos de bacias são separados por um grande escarpamento, herança dos processos que colimaram na abertura mesocenozoica do Atlântico Sul. A compartimentação geomorfológica desses planaltos comprova o papel fundamental exercido pelo arcabouço litoestrutural na evolução e configuração da paisagem, bem como revela a participação de uma tectônica recente (cenozoica. As análises efetivadas neste trabalho se fundamentam no desnivelamento altimétrico que vigora na organização do relevo regional, à conta de remanescentes de blocos tectonizados e associados à diversidade litoestrutural. Os mapeamentos realizados comprovam a existência de três macrocompartimentos geomorfológicos, cuja morfologia regional manifesta caimentos topográficos em dois sentidos principais: para NW, nos degraus Paraná - São Francisco e Doce; para SE, no degrau Paraíba do Sul. Na morfogênese desses degraus foi fundamental o processo de retração denudacional das escarpas que, em múltiplas dimensões espaço-temporais, se articulou a condicionantes tectônicos e estruturais. As diferenças na dissecação das bacias costeiras indicam a atuação de níveis de base locais e uma resposta à orientação de estruturas regionais. As estruturas impõem um controle regional sobre a evolução da rede de drenagem com direção preferencial NE-SW. Anomalias de drenagem se encontram associadas ao controle litoestrutural e implicaram na reorganização da rede hidrográfica.

    The single-nucleotide polymorphisms (SNPs) of the Mina gene in animals are associated with the development of Th2-mediated diseases. However, there is no information whether the association occurs in humans. This case-control study aimed at examining the potential association of the SNP of the Mina gene with the development of asthma in Chinese Han children. The DNA genotypes and serum immunoglobulin E and interleukin-4 levels of 202 asthmatic patients and 191 nonasthmatic subjects were determined by matrix-assisted laser desorption ionization-time of flight mass spectrometry method and enzyme-linked immunosorbent assay, respectively. We found that the frequency of the T allele of rs4857304, but not rs832081, rs832078, rs9879532, and rs17374916, in the Mina gene in asthmatic patients was significantly higher than that of controls (p = 0.0199). Using a recessive model, we found that the percentage of patients with TT homozygous rs4857304 was significantly higher than that of controls (p = 0.0282, odds ratio=1.568, 95% confidence interval=1.048-2.346). Further, the mean levels of serum immunoglobulin E and interleukin-4 in the patients with TT genotype of rs4857304 were significantly higher than that of patients with the G allele (p = 0.000 and p = 0.03, respectively). Apparently, the T allele of rs4857304 of the Mina gene may be associated with increased risk for the development of asthma in Chinese Han children.

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

    Among food poisoning of microbial origin, S. aureus stands as one of the most important, being a pathogenic bacteria for as human kind and of important occurrence in food products. Although 'Minas Frescal' cheese is typically Brazilian, there aren't in this country technical rules for its preparation and appropriate inspection. In the present work the effect of gamma radiation on the resistance of S. aureus and its ability to produce toxins in 'Minas Frescal' cheese were evaluated. The effects of the radiation in 'Minas Frescal' cheese physical-chemical and sensory properties will be determined, with the objective of studying the efficiency of the gamma radiation as method of conservation of this product. During the fabrication of 'Minas Frescal' cheese in the Laboratory of Irradiation of Foods (CENA/USP), S. aureus strains (ATCC 13565, ATCC 14458, ATCC 19095) with approximate count of 106 UFC/ml were inoculated. After irradiation with doses of O(control); 1; 2; 3 and 4 kGy, the cheeses were stored under refrigeration (+- 5 deg C) and analyzed at 1, 7 and 14 days. After irradiation with doses of O(control); 1; 2; 3 and 4 kGy, the cheeses were stored under refrigeration (+- 5 deg C) and analyzed at 1,7 and 14 days. 'Minas Frescal' cheese was evaluated through the determination of parameters of acidity, pH, moisture and lever of extension proteolysis, according to methodology of Association of Official Analytical Chemists (AO.AC.),1995, and sensory analysis by the ADQ (Quantitative Descriptive Analysis) method. The microbiological analysis determined the survival of S. aureus in the Baird-Parker a selective medium and its ability of producing enterotoxin by the Passive Reverse Agglutination with Latex method. the results analyzed through randomized blocks in a factorial design (5x3), revealed that 'Minas Frescal' cheese did not present significant differences among the radiation doses in relation to its physical-chemical and sensory properties.

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

    Full Text Available A produção de café orgânico vem se constituindo uma tendência necessária e irreversível do agronegócio brasileiro. Essa atividade tem-se destacado como uma alternativa de renda para alguns cafeicultores, devido à crescente demanda mundial por alimentos mais saudáveis. Entretanto, grande parte das técnicas propostas pela agricultura orgânica está sendo aplicada empiricamente no cultivo de café, principalmente no Estado de Minas Gerais, maior região produtora de café do Brasil. Levando-se em consideração a baixa fertilidade natural dos solos dessa região cafeeira, bem como a elevada extração de nutrientes pelo cafeeiro, objetivou-se neste trabalho identificar possíveis fatores limitantes para a produção orgânica do cafeeiro, relacionados à fertilidade do solo e ao estado nutricional das plantas. Foram realizadas avaliações da fertilidade do solo e análise das folhas em vinte e uma lavouras orgânicas representativas do Estado de Minas Gerais. As amostras de solo foram analisadas para determinação do pH, acidez potencial e dos teores de P, K, Ca, Mg, S, Al e matéria orgânica. As amostras foliares foram analisadas para determinação dos teores de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn. Com base nos padrões de interpretação para cafeeiros convencionais propostos pela literatura, estabeleceram-se as freqüências com que os caracteres analisados foram inferiores aos critérios de interpretação da fertilidade do solo e estado nutricional das plantas. A análise dos dados foi realizada por estatística descritiva. Novos trabalhos nessa nova área são necessários, visando a uma melhor interpretação da análise foliar e da fertilidade do solo, quando se trabalha com café orgânico.The production of organic coffee have been shown as a necessary and irreversible tendency of brazilian agrobusiness.

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.

En este sentido, la intervención sobre los polígonos de vivienda masiva construidos en las ciudades españolas hace cuarenta o cincuenta años —muchos de los cuales se hallan sometidos en la actualidad a procesos de degradación y marginalidad de cierta envergadura— es una de las experiencias de mayor interés por su notable complejidad, ya que en ellos se entrelazan de manera inseparable los aspectos físicos y sociales. Este artículo se centra en uno de los casos españoles más relevantes de este tipo de intervenciones: el plan para la transformación del barrio barcelonés de la Mina, desarrollado en torno a un Plan Especial de Reordenación y Mejora aprobado en 2002 y ya ejecutado en gran parte. Por la sensatez de sus planteamientos y por la operatividad de sus propuestas, la actuación ha sido objeto de numerosos reconocimientos a nivel nacional e internacional. Vivienda colectiva y espacio público constituyen dos de los ejes que vertebran todo el proyecto urbano de la Mina; aquí se presta particular atención al análisis de las actuaciones relacionadas con el tejido residencial y a las estrategias para relacionar las nuevas manzanas habitacionales con un renovado sistema de espacios libres.

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

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.

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

A tendency to the decrease of canine rabies positive cases was found (y= -3.2143x + 19.714 and the same was observed for cats, since only two cases occurred, both in 2000. The regions that present positive diagnostics also showed the lowest social economic development.

    Full Text Available O objetivo deste trabalho é avaliar o desempenho de 4 modelos utilizandodiferentes conjuntos de variáveis ambientais, variando em complexidade,na tentativa de prever a distribuição geográfi ca de Amaioua guianensisAubl. no Estado de Minas Gerais. Os pontos de ocorrência da espécie foramrecuperados no banco de dados TreeAtlan 1.0 para o Estado de Minas Gerais.As bases ambientais utilizadas para o trabalho compreendem coberturasclimáticas relacionadas com temperatura e precipitação, dados relativos aorelevo, distância do oceano, índices de vegetação do sensor MODIS, tipo desolo e litologia. Para a modelagem de distribuição da espécie foi utilizado oalgoritmo de Máxima Entropia (Maxent. Quatro alternativas de conjuntosde variáveis, foram gerados: com toda a base de dados, só com as variáveisbioclimáticas, com as variáveis selecionadas por meio da CCA e com asvariáveis selecionadas por meio de uma análise prévia do teste Jackknife paratodas as variáveis. A análise do desempenho dos modelos foi feita utilizadoa área sob a curva ROC e taxas de omissão extrínsecas. As simulações demonstram que a seleção de variáveis ambientais mais relevantes para umadeterminada espécie produz modelos mais acurados.

    Full Text Available No presente estudo foi analisado a dieta de Enyalius perditus Jackson, 1978 e suas variações de acordo com disponibilidade de alimento no Parque Estadual do Ibitipoca, Minas Gerais, Brasil. Três áreas de matas foram amostradas, utilizando-se armadilhas de queda e adesivas para captura dos lagartos e itens-presa disponíveis. Os lagartos (n= 55 foram dissecados e o conteúdo estomacal analisado. O Índice de eletividade mostrou que larvas foram importantes volumetricamente na dieta de E. perditus, enquanto que formigas e isópodos foram importantes numericamente. A quantidade de itens nas dietas de machos e fêmeas diferiram estatisticamente, talvez como uma conseqüência da maior quantidade de formigas ingeridas pelas fêmeas e isópodos e larvas pelos machos. Baseado no comportamento alimentar, os machos são mais semelhantes aos forrageadores ativos e as fêmeas, aos predadores senta-e-espera.The present study was carried out to describe the diet, and its variations according to food availability, in Enyalius perditus Jackson, 1978 from Parque Estadual do Ibitipoca, State of Minas Gerais, Brazil. Three areas were chosen in the forest fragments; pit falls and glue traps were used to capture lizards and their preys. Lizards (n=55 were dissected in order to analyze the stomach content. The Electivity Index showed that insect larvae were volumetrically important in the diet of E. perditus, while ants and woodlices where numerically important. The quantity of diet items have differed significantly between males and females, perhaps, as a consequence of the higher quantity of ants ingested by female lizards and larvae ingested by males lizards. Based upon alimentary behavior, the male lizards resemble the active forragers and the females sit and wait forragers.
