Full Text Available A cobertura do solo é o fator de maior importância relativa no controle da erosão hídrica. Assim, objetivou-se no presente estudo elaborar a modelagem da cobertura vegetal de vinte e quatro plantas de cobertura, em diversos sistemas de plantio e históricos de uso, com potencial para cultivo no Sul de Minas Gerais. Para avaliação da cobertura vegetal foram realizadas avaliações no campo utilizando uma régua de classificação da cobertura vegetal, sendo o delineamento experimental inteiramente casualizado, com três repetições, utilizado neste experimento. As plantas cultivadas sobre a palhada de feijãoirrigado apresentaram alto índice de cobertura do solo, o que pode estar relacionado à maior disponibilidade de nutrientes deixado por esta cultura na palhada e a maior reserva de água no solo, promovido pela irrigação do feijão. O milheto cultivado em nível e sobre a palhada de milheto e feijão-de-porco apresentou o menor índice de cobertura entre as plantas testadas. Na região sul de Minas Gerais os padrões de chuvas ocorrem em maior quantidade nos períodos de outubro a março, com elevação em dezembro e janeiro. Neste período o solo deve estar protegido do impacto da gota de chuva, pois o risco de erosão hídrica é maior. Assim, a utilização das plantas de cobertura é de grande importância, pois estas protegem o solo do impacto direto dasgotas de chuvas e diminuem os picos de temperatura do solo, sendo que estas devem ser cultivadas, preferencialmente, sobre a palhada de feijão.The ground cover is the most important factor relative to control erosion. Thus, the objective of this study was to develop a model plant cover for 24 cover crops used in several cropping systems and historical use, with potential for cultivation in southern Minas Gerais State, Brazil.

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.

In an attempt to elucidate the regional geological evolution of the Ouro Preto and Mariana Districts, SE Quadrilatero Ferrifero, Minas Gerais, the available petrographical and structural data were interpreted together with 5 Rb/Sr and 7 K/Ar age determinations. Various types of metamorphic rocks were identified, and four phases of regional petrographic evolution could be distinguished: a) pre-metamorphic phase indicated by relict sedimentary and other textures; b) pre-deformation metamorphic phase, manifested by several minerals, such as microcline; c) major syntectonic crystallization phase associated with the main regional diastrophism, presumaby the Minas orogeny; d) post-deformation phase, with retrograde metamorphic minerals. With one exception, the apparent K/Ar ages obtained on biotites and amphiboles were concordant, ranging between 480 and 540 m.y., and can be referred to the terminal episodes of cooling in the Brazilian cycle. The Rb/Sr data obtained from 3 whole-rock analyses, when plotted on a Sr 87 /Sr 86 - Rb 87 /Sr 86 diagram, indicated an age of approximately 2.000m.y., with an initial Sr 87 /Sr 86 ratio of 0.711. In this diagram, 2 other speciments from a single outerop plotted significantly above of the reference isochron of 2.000m.y. The apparent ages of about 2.700 m.y. are concordant with those for the Barbacena Group which occurs more toward the eastern side of the study area. From interpretation of petrographical and structural data, the following regional geological evolution can be inferred; a)2.700m.y. - Formation of rocks during the pre-Minas episode (diastrophism in Barbacena Series, or in the Bacao Complex; b) 2.000m.y. - Trans-Amazonian cycle - Main phase of syntectonic crystallization - Minas Series diastrophism; c) 500-600m.y. - Brazilian cycle - retrograde metamorphism, thrust tectonics and regional fracturing.

Full Text Available Minas Gerais foi, durante o século 19 e início da centúria seguinte, o mais importante espaço canavieiro do Brasil. Para a década de 1830, estima-se a existência em Minas de 4.150 unidades produtivas com transformação da cana-de-açúcar. A soma dos engenhos do litoral nordestino, do norte fluminense e do Planalto Paulista não alcançava a metade do número de engenhos mineiros. Para este mesmo período, estima-se que em Minas 85 mil cativos eram empregados na fabricação de açúcar e aguardente. Em nenhum outro espaço canavieiro, em qualquer período da história do Brasil escravista, foi empregado contingente desta magnitude. Ainda para a quarta década do Oitocentos, estima-se que Minas Gerais produzia 33.200 toneladas de açúcar. A produção paulista não superava 8.500 toneladas e a de Pernambuco era de 27 mil. As exportações de açúcar da Bahia não perfaziam 30 mil toneladas, e as do Rio de Janeiro não alcançavam 17 mil.During 19th century and the beginning of the following century, Minas Gerais was the most important sugarcane plantation area in Brazil. In the 1830's, there were 4.150 productive unities working with sugarcane transformation in Minas. The sum of all sugar mills in the northeast coast, north of Rio de Janeiro and the plains of São Paulo did not reach half of the number of sugar mills in Minas Gerais. In the same period, it is estimated that 85.000 captives was employed in the fabrication of sugar and of aguardente. That such a large contingent had neither been employed in any other sugarcane plantation area nor in any other period of brazilian slavery history. Furthermore, it is estimated that in the 1830's Minas Gerais produced 33.200 tons of sugar. The sugar production of São Paulo did not surpass 8.500 tons, and the production of Pernambuco was 27.000. The sugar exportation of Bahia was not more than 30.000 tons and the amount exported by Rio de Janeiro did not reach 17.000.

Full Text Available An electronic equipment based on the infrared spectroscopy was evaluated to measure the whey composition in "Minas padrão" and "prato" cheeses. The results for fat, protein, and total solids using infrared instrument based on filters and using standard methods were compared. There were differences between the values obtained from both analytical methods, and since compounds formed during heating of the analyzed whey may have interfered with infrared spectrum readings, a linear transformation of the data was done. After this statistical adjustment, results for "Minas padrão" cheese were equivalent in both infrared and standard methods. For "prato" cheese whey, the difference was significant, even after the adjustment.

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

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.

Fault Slip Partitioning in the Eastern California Shear Zone-Walker Lane Belt: Pliocene to Late Pleistocene Contraction Across the Mina Deflection

Science.gov (United States)

Lee, J.; Stockli, D.; Gosse, J.

2007-12-01

Two different mechanisms have been proposed for fault slip transfer between the subparallel NW-striking dextral- slip faults that dominant the Eastern California Shear Zone (ECSZ)-Walker Lane Belt (WLB). In the northern WLB, domains of sinistral-slip along NE-striking faults and clockwise block rotation within a zone of distributed deformation accommodated NW-dextral shear. A somewhat modified version of this mechanism was also proposed for the Mina deflection, southern WLB, whereby NE-striking sinistral faults formed as conjugate faults to the primary zone of NW-dextral shear; clockwise rotation of the blocks bounding the sinistral faults accommodated dextral slip. In contrast, in the northern ECSZ and Mina deflection, domains of NE-striking pure dip-slip normal faults, bounded by NW-striking dextral-slip faults, exhibited no rotation; the proposed mechanism of slip transfer was one of right-stepping, high angle normal faults in which the magnitude of extension was proportional to the amount of strike-slip motion transferred. New geologic mapping, tectonic geomorphologic, and geochronologic data from the Queen Valley area, southern Mina deflection constrain Pliocene to late Quaternary fault geometries, slip orientations, slip magnitudes, and slip rates that bear on the mechanism of fault slip transfer from the relatively narrow northern ECSZ to the broad deformation zone that defines the Mina deflection. Four different fault types and orientations cut across the Queen Valley area: (1) The NE-striking normal-slip Queen Valley fault; (2) NE-striking sinistral faults; (3) the NW-striking dextral Coyote Springs fault, which merges into (4) a set of EW-striking thrust faults. (U-Th)/He apatite and cosmogenic radionuclide data, combined with magnitude of fault offset measurements, indicate a Pliocene to late Pleistocene horizontal extension rate of 0.2-0.3 mm/yr across the Queen Valley fault. Our results, combined with published slip rates for the dextral White Mountain

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

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.

Full Text Available The sheep’s milk has high contents of fat, protein and minerals in relation to the cow’s milk and is suitable for the production of cheeses, as the Minas fresh. 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.

Characterize anemia in children aged between 12 and 59 months from urban areas in the provinces of Coronel Portillo and Huancavelica in Peru. Cross-sectional study carried out in two stages: a) population-based study to identify children with anemia using multistage probability sampling, and b) characterization of the serum levels of ferritin, vitamin B12, intraerythrocytic folic acid and presence of parasitosis in children with anemia. For the statistical analysis, expansion factors calculated from the sampling plan were applied. The prevalence of anemia was 55.9% in Huancavelica and 36.2% in Coronel Portillo. In Huancavelica, the coexistence of anemia with iron deficiency was 22.8% and anemia with vitamin B12 deficiency was 11%. In Coronel Portillo, the coexistence of anemia with iron deficiency and vitamin B12 deficiency was 15.2% and 29.7%, respectively. The most common types of anemia in Huancavelica were anemia with concurrent parasitosis (50.9%), iron deficiency anemia and parasitosis (12.3%), and iron deficiency alone (6.4%). In Coronel Portillo, it was anemia and parasitosis (54.4%), vitamin B12 deficiency and parasitosis (18.4%), and iron deficiency anemia and parasitosis (6.3%). The prevalence of anemia is higher than the national average, with anemia concurrent with parasitosis and anemia concurrent with two or more causes as the most common type. Consideration should be given to different causes other than iron deficiency in the programs of anemia contol for Peruvian children.

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.

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.

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 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.

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 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.

On April 27, 1986, at least 8 million liters of medium-weight crude oil spilled from a ruptured storage tank into the Bahia Las Minas on the Caribbean Coast of Panama. Coral reefs, seagrass communities, and mangroves were affected. The area of the spill was also the location of the Smithsonian Tropical Research Institute's Galeta Laboratory where resident and visiting scientists have been studying the ecology of the Bahia Las Minas and the adjacent areas for over 15 years. Because this was a unique opportunity to assess the immediate biological effects following a major spill in the Caribbean region and to monitor the subsequent recovery, the U.S. Department of the Interior Minerals Management Service supported a 5-year environmental study. The objectives of the study are to identify any long-term changes in the marine environment that may have resulted from the spill and to understand the ecological processes causing such changes. This is the first report from the study and addresses the effects observed during the first two years of the effort

Molecularly imprinted polymer nanoparticle-based assay (MINA): application for fumonisin B1 determination.

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%.

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.

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

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 OBJECTIVE: To assess factors influencing perspectives on Brazil's national Family Health Program (PSF by exploring satisfaction with PSF units and home-visit community health agents and perceptions about PSF unit accessibility among frequent users (primary caretakers of children under age 5 in Vespasiano, Minas Gerais. METHODS: Data were collected though cross-sectional household surveys to determine pro grammatic and demographic factors affecting user satisfaction with the PSF. Multivariate logistic modeling was used to estimate users' satisfaction with PSF units and agents and perceived access to PSF unit services. Chi-square and analysis of variance (ANOVA tests were used to estimate statistical differences. RESULTS: The majority of caretakers were satisfied with both their PSF unit and their PSF community health agent and had received at least one monthly home visit from the health agent. Satisfaction with both the health agent and the unit was positively associated with per ceived access to the unit and frequency of agent home visits. Caretakers who reported that their PSF agent made one or more home visits per month were more likely to perceive the PSF unit as being "accessible" (or "sometimes accessible". CONCLUSIONS: The current data are important indicators of population health in Minas Gerais, Brazil, and suggest that users' satisfaction with the PSF and perceptions about its accessibility can be improved by ensuring that all households receive at least one health agent home visit per month. These results could be applied to other parts of Brazil or Latin America to improve understanding of user perceptions of health systems.OBJETIVO: Evaluar los factores que influyen en las perspectivas sobre el Programa de Salud Familiar (PSF del Brasil, mediante el análisis de la satisfacción de los usuarios frecuentes del PSF (cuidadores primarios de niños menores de 5 años con las unidades y los agentes de salud comunitarios que efectúan las

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)

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)

Pers allied to the analysis of the energetic efficiency. The data used in this project were collected from EMBRAPA Gado de Leite, localized in Coronel Pacheco, Minas Gerais, Brazil. The data were obtained from a seven year period of an intensive system of milk production. Energetic coefficients were used to generate the survey and several matrix components obtained from pertinent literature. The direct energy, related to the inputs, showed more efficient participation on the energetic matrix than the indirect energy and the percentages were 94.64 and 5.31, respectively. Farm tractor was the main indirect energy consumer, which is responsible for turning on all the equipment, followed by the irrigation system. The energetic efficiency presented by the whole system was 4.2, being considered positive and demonstrating that the agriculture ecosystem is sustainable. Most of the direct energy employed in this system was oil derived on fuel form. There was, however, a great consume of another oil derived energy such as fertilizer, but mainly on the nitrogen form (28.89% of the total employed energy). (author)

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.

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

The first three species of Biomphalaria, recognized as intermediate hosts of S. mansoni, were present in 33.3%, 47.2% and 8.3% of the municipalities studied, respectively. The mollusks were found in different types of water collections and no infection by S. mansoni was detected. The highest occurrence of Biomphalaria concentration was verified in the area covered by the Caminho Novo route (Diamantina/MG to Rio de Janeiro/RJ. CONCLUSIONS: Considering the occurrence of schistosomiasis in the State of Minas Gerais and the socioeconomic repercussions involved in the Estrada Real Project, this work focuses on the vulnerability of water collections due to the presence of Biomphalaria mollusks and emphasizes the need for epidemiological surveillance and sanitary and educational measures integrated with the local community and tourism sectors.

1986-01-01

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 Producers need wheat cultivars adapted to the predominant climate conditions of the end of the rainy period. Having this in mind, EPAMIG (Agriculture and Livestock Research Institute of Minas Gerais has been developing a wheat genetic improvement program since 1976, and the estimates of the genetic improvement established by the breeding programs could be useful to quantify their efficiency. This study focused on the quantification of the genetic progress achieved by these improvement programs of dryland wheat in the Brazilian-savanna between 1976 and 2005. The efficiency of these programs was evaluated based on grain yield data of VCU (Value for Cultivation and Use trials conducted at ten locations in the Minas Gerais State, Brazil. The mean estimated genetic progress for mean grain yield between 1976 and 2005 was 37 kg ha-1 year-1. The genetic yield gain in the study period indicates that the improvement programs of dryland wheat in the Brazilian-savanna are effective. Besides the marked contribution of genetic gain, the environmental and technological improvements were also relevant for the yield, accounting for 47.4% of the total progress in the period. The improvement programs of dryland wheat resulted in a genotype renovation rate of 35% over the years.Devido à necessidade dos produtores por cultivares de trigo adaptados às condições climáticas do final da época das chuvas, desde 1976 a EPAMIG (Empresa de Pesquisa Agropecuária de Minas Gerais vem desenvolvendo um programa de melhoramento genético.

Nesse aspecto, a produção de novos materiais genéticos é uma alternativa viável e necessária para minimizar este entrave. O objetivo deste trabalho foi selecionar diferentes clones de ameixeira visando à obtenção de plantas com alta produtividade e frutos de boa qualidade, com maturação escalonada e adaptados às condições climáticas do sul de Minas Gerais. Foram selecionadas plantas de um antigo pomar comercial, localizado no Município de Wenceslau Braz - MG. Estas plantas estavam vegetando e produzindo em condições totalmente adversas, sem quaisquer tratos culturais. Após identificação, foram coletados dados fenológicos de coloração da flor, épocas de brotação e floração. Nos frutos, foram avaliados: época de maturação (início e fim, tamanho, forma, descrição da película, descrição da polpa, ocorrência de pragas e doenças. Após um período de avaliação de dois ciclos produtivos (1996-1997 e 1997-1998, foram selecionados clones com características favoráveis, principalmente com relação às épocas de floração e maturação dos frutos e adaptação ambiental.

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.

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)

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.

Up to 10% of the liquid hydrocarbons of the Golfo San Jorge basin come from the Mina del Carmen Formation (Albian), an ash-dominated fluvial succession preserved in a variably integrated channel network that evolved coeval to an extensional tectonic event, poorly analyzed up to date. Fault orientation, throw distribution and kinematics of fault populations affecting the Mina del Carmen Formation were investigated using a 3D seismic dataset in the Cerro Dragón field (Eastern Sector of the Golfo San Jorge basin). Thickness maps of the seismic sub-units that integrate the Mina del Carmen Formation, named MEC-A-MEC-C in ascending order, and mapping of fluvial channels performed applying geophysical tools of visualization were integrated to the kinematical analysis of 20 main normal faults of the field. The study provides examples of changes in fault throw patterns with time, associated with faults of different orientations. The "main synrift phase" is characterized by NE-SW striking (mean Az = 49°), basement-involved normal faults that attains its maximum throw on top of the volcanic basement; this set of faults was active during deposition of the Las Heras Group and Pozo D-129 formation. A "second synrift phase" is recognized by E-W striking normal faults (mean Az = 91°) that nucleated and propagated from the Albian Mina del Carmen Formation. Fault activity was localized during deposition of the MEC-A sub-unit, but generalized during deposition of MEC-B sub-unit, producing centripetal and partially isolated depocenters. Upward decreasing in fault activity is inferred by more gradual thickness variation of MEC-C and the overlying Lower Member of Bajo Barreal Formation, evidencing passive infilling of relief associated to fault boundaries, and conformation of wider depocenters with well integrated networks of channels of larger dimensions but random orientation. Lately, the Mina del Carmen Formation was affected by the downward propagation of E-W to ESE-WNW striking

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.

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.

Full Text Available Na cultura do arroz irrigado, não foram observadas diferenças significativas no rendimento de grãos em experimentos de campo que confrontaram fontes solúveis e fosfatos naturais como fontes de P. No entanto, as alterações químicas que ocorrem durante o alagamento, principalmente aumento do pH e dos teores de P e Ca na solução do solo, provavelmente dificultam a dissolução de fosfatos naturais. O objetivo deste trabalho foi avaliar a solubilização dos fosfatos naturais de Patos de Minas e de Arad em dois solos alagados. Foram realizados dois experimentos, delineados em blocos ao acaso, com quatro repetições, em tipos de solos diferentes (Planossolo e Cambissolo. Foram testadas fontes de P: (a testemunha, sem P; (b superfosfato triplo; (c fosfato de Patos de Minas; e (d fosfato de Arad. Na solução do solo, foram avaliados os valores de pH e os teores de Fe, Mn, Ca, e P durante 88 dias de alagamento. O pH e os teores de Fe e Mn na solução do Planossolo e do Cambissolo não foram influenciados pela adição de superfosfato triplo e pelos fosfatos naturais de Arad e de Patos. Os teores de P na solução dos solos foram maiores com superfosfato triplo do que com os fosfatos naturais, indicando maior solubilização do primeiro durante o alagamento. Entre os fosfatos naturais, o de Arad apresentou maior solubilização do que o de Patos apenas no Planossolo.Differences in grain yield were not observed in experiments with paddy rice when comparing soluble phosphates and rock phosphate as phosphorus sources. However, chemical changes in flooded soils such as increases in pH and phosphorus and calcium levels in the soil solution probably decrease the dissolution of rock phosphates in flooded soils. The current work was therefore carried out with the objective of studying the solubilization of phosphate rocks in flooded soils. Two experiments, conducted in a random block design with four replications, were set up in two soil types

Objective Congenital toxoplasmosis is a public health problem in Brazil. This study aimed to determine risk factors associated with congenital toxoplasmosis in Minas Gerais which is the second largest Brazilian State based on number of inhabitants, and its territorial extension is larger than that of France. Methods: Population-based case-control study to assess the association between congenital toxoplasmosis and maternal exposure to infection risk factors. The study included mothers/children participating in the Minas Gerais Newborn Screening Program. The cases consisted of 175 mothers of infected children, and the controls consisted of 278 mothers of children without suspected infection. The associations were assessed through binomial logistic regression with p≤0.05. Results The variables associated with lower probability of toxoplasmosis were: older mother age (OR = 0.89; CI95% = 0.85–0.93), higher level of education (OR = 0.85; CI95% = 0.78–0.92), access to potable water (OR = 0.21; CI95% = 0.08–0.51), and home with flush toilet (OR = 0.18; CI95% = 0.04–078). The variables associated with higher probability of infection were: cats in the neighborhood (OR = 2.27; CI95% = 1.27–4.06), owning or visiting homes with domestic cats (OR = 1.90; CI95% = 1.09–3.31), handling the soil (OR = 2.29; CI95% = 1.32–3.96), and eating fresh meat not previously frozen (OR = 3.97; CI95% = 2.17–7.25). After stratification according region of residence (rural or urban/peri-urban), home with flush toilet and consumption of treated water were protective against the disease only in the rural stratum. Conclusions In Minas Gerais, congenital toxoplasmosis has been associated with poor socioeconomic conditions. Considering maternal exposure to sources of Toxoplasma gondii, the predominating risk factors were those related to the ingestion of oocysts. It is expected that these results will contribute to

Full Text Available A pyrochlore to perovskite transformation is known to occur during the rapid heating of sol-gel prepared La modified lead titanate ferroelectric thin films. This transformation is not inhibited by the Pb deficiency caused by PbO volatilisation at the initial stages of the thermal treatment. The microstructural evolution associated with this transformation occurring in the Pb deficient film has been studied by transmission electron microscopy. Plan view and cross section specimens were prepared from two films at different stages of the transformation. Experiments showed that the pyrochlore phase was homogenously distributed across the film thickness, with a very similar morphology to that of the ferroelectric phase. The combination of microdiffraction and microanalysis allowed identifying single grains that had not the perovskite structure, and were more Pb deficient than the film. Pore growth, grain growth, and growth of local texturing were observed along with the transformation.Es conocido que se produce una transformación de estructura pirocloro a perovskita durante el calentamiento rápido de láminas delgadas ferroeléctricas de titanato de plomo modificadas con La, preparadas por sol-gel. La deficiencia de Pb causada por la volatilización de PbO en los primeros momentos del tratamiento térmico no inhibe la transformación. Se ha estudiado, por microscopía electrónica de transmisión, la evolución microestructural asociada a esta transformación, que ocurre en un medio que en promedio es deficiente en Pb. Con este fin, se prepararon muestras para microscopía, tanto del plano de la lámina como secciones transversales, a partir de dos láminas en las que la transformación se encontraba en estadios diferentes. Los experimentos pusieron de manifiesto que la fase con estructura pirocloro se encontraba homogéneamente distribuida a lo largo del espesor de la lámina, y que su morfología era muy similar a la de la fase ferroel

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.

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.

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.

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.

Full Text Available As cooperativas devem possuir uma estrutura de capital coerente com os objetivos dos associados e ser administradas com vistas a manter a empresa competitiva. 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.

Galls and host plants were collected along transects in a total of 3,000 herbs, 300 shrubs and 135 trees in each physiognomy. Ninety two species of galling insects (morphotypes on 62 host plant species of 28 families were found. The highest galling insect richness was observed in the "cerrado". Approximately 75.0% of galling insects belonged to the Cecidomyiidae (Diptera. The highest gall frequency was found on leaves (58.70% of the host plants, and was glabrous (83.70%. Most gall shape were elliptic (30.43%. A low similarity in galling insect species was observed among the three sampled physiognomies - the highest similarity index was observed between "cerrado" and "campo sujo" (SΦrensen index = 0.20, indicating that the presence of rare species of galling insects might be common in these environments.

A redução do volume de Crédito Rural oficial e a implementação do Plano Real provocaram mudanças no sistema financeiro. Nesse contexto, buscou-se avaliar, a partir da estrutura financeira, se as cooperativas de crédito encontram-se em estado de solvência ou insolvência, por meio da verificação de seus indicadores financeiros. Empregou-se o modelo Logit e a área de estudo envolveu as cooperativas do Estado de Minas Gerais, no período de 1998 a 2001. Constatou-se que os indicadores importantes para predição de insolvência foram capitalização, cobertura voluntária e crescimento da captação total. Verificou-se, em agosto de 2001, que 98,06% das cooperativas de crédito rural do Estado de Minas Gerais estavam solventes, o que indica a importância e efetividade do sistema em atender às demandas de crédito por parte do produtor rural.Credit unions are an alternative to make possible to the agricultural producer access for credit obtaining. The reduction of the official agricultural loan program and the implementation of the monetary stabilization plan of 1994 caused changes in the Brazilian financial system. So, the objective of this study was to evaluate, from the financial structure, the state of solvency of the rural credit unions, by the verification of financial indicators. It was used the Logit Model and the sample was formed from the credit unions of the Minas Gerais State, Brazil, between 1998 and 2001. The results indicated that the relevant ratios for insolvency prediction were capitalization, volunteer covering e total capitation growth. It was also verified that, in august 2001, 98,6% of the agricultural credit cooperatives were in solvency state, suggesting the importance and effectiveness of system as a supplier for the credit needs of the agricultural producers.

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

Full Text Available Geographic Information Systems (GISs are composed of useful tools to map and to model the spatial distribution of events that have geographic importance as schistosomiasis. This paper is a review of the use the indicator kriging, implemented on the Georeferenced Information Processing System (SPRING to make inferences about the prevalence of schistosomiasis and the presence of the species of Biomphalaria, intermediate hosts of Schistosoma mansoni, in areas without this information, in the Minas Gerais State, Brazil. The results were two maps. The first one was a map of Biomphalaria species, and the second was a new map of estimated prevalence of schistosomiasis. The obtained results showed that the indicator kriging can be used to better allocate resources for study and control of schistosomiasis in areas with transmission or the possibility of disease transmission.

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.

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.

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.

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

Full Text Available Devido às poucas informações sobre as práticas de cultivo do capim-limão (Cymbopogon citratus, DC. objetivou-se avaliar o efeito de lâminas de irrigação sobre: a produção de biomassa, o rendimento e composição do óleo essencial. O experimento foi instalado em ambiente protegido para possibilitar o controle das lâminas de irrigação e avaliar a viabilidade para situações em que as condições climáticas normais sejam inadequadas. O delineamento experimental foi em blocos inteiramente casualizados com cinco tratamentos e três repetições. Os dados foram submetidos à análise de variância pelo tese F e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Na etapa um, os tratamentos consistiram da aplicação de lâminas referentes a 50%, 75%, 100%, 125% da evapotranspiração da cultura (ETc, irrigando duas vezes por semana e de 100% da evapotranspiração da cultura (ETc, irrigando uma vez por semana, sendo denominados de T1, T2, T3, T4 e T5, respectivamente. Na etapa dois, os tratamentos consistiram da aplicação de lâminas referentes a 50%, 75%, 100%, 125% da ETc irrigando uma vez por semana e de 100% da ETc, irrigando a cada 14 dias, sendo denominados de T6, T7, T8, T9 e T10 respectivamente. O corte do capim-limão foi realizado após 60 dias do início dos tratamentos. Avaliou-se a altura de plantas, o número de perfilhos por touceira, a massa seca da parte aérea, o rendimento e a composição do óleo essencial. O T5, caracterizado por estresse hídrico e intervalo de irrigação moderado, foi o que apresentou a maior produção de matéria seca, maior produtividade do capim-limão e maior estimativa da produtividade de óleo essencial e maior concentração de citral, na primeira etapa. Na etapa dois, o T6, correspondente ao estresse hídrico crescente e acentuado, foi o que apresentou maior estimativa da produtividade de óleo essencial. De acordo com os resultados observados, não foi possível definir

Após a fase do pioneirismo (P. Lund, amadores diversos, missões internacionais estudam a região de Lagoa Santa no terceiro quarto do século XX, enquanto o Programa Nacional de Pesquisas Arqueológicas (PRONAPA inicia levantamentos no alto vale do rio São Francisco. Com a abertura de pesquisas mais sistemáticas pelo Instituto de Arqueologia Brasileira (IAB no Norte mineiro e a criação do Setor de Pesquisa da UFMG, na segunda metade dos anos de 1970, abre-se uma fase de pesquisas mais intensivas e regionais, tematicamente diversificadas. O início deste século XXI é marcado pela multiplicação das pesquisas preventivas e de resgate, a emergência de novos centros de pesquisa e a criação de cursos de formação de arqueólogos na UFMG. O Patrimônio pré-histórico de Minas Gerais é notável pela importância de preservação de materiais perecíveis, de restos esqueletais humanos de grande antiguidade, pela riqueza dos registros rupestres e a variedade regional das indústrias realizadas sobre matérias-primas muito diversas. A arqueologia histórica, cuja importância cresceu exponencialmente nos dois últimos decênios, é marcada pela importância dos vestígios da mineração de pedras e metais preciosos, dos assentamentos de escravos fugitivos e os remanescentes de fazendas antigas, cujo estudo se desenvolveu comparativamente mais que a arqueologia da urbanização e dos monumentos barrocos.

Pretende-se avaliar se a opinião pública em relação ao legislativo estadual se mostrou "resistente" às inovações institucionais ou se ocorreram mudanças ao longo dos treze anos cobertos pelos dados disponíveis. A análise comparativa no tempo e com outras instituições políticas não nos autoriza a falar sobre uma excepcionalidade da ALMG no que se refere a sua imagem pública. Em grande medida, a imagem da ALMG, em termos de confiança e avaliação, não foge do padrão brasileiro em relação às instituições políticas. O impacto do processo de inovação institucional é perceptível apenas sobre um público restrito: aqueles que consumiram as mensagens e comunicações produzidas pela ALMG e veiculadas no radio e na televisão.This article analyzes the impact on public opinion of the strategies of communication carried out by the Legislative Chamber of Minas Gerais (ALMG during the 1990's. We evaluate whether the public opinion on the state legislature has changed along of this thirteen years, following a steady process of institutional innovation. Comparing results for different points of time between 1993 and 2006, we reject the idea that ALMG's public image is substantially different from standard public evaluation of Brazilian political institutions. We find that the institutional change process is noticeable and has a positive response only for the small public attentive to ALMG's messages transmitted by radio and television.

Full Text Available ABSTRACT. Chrysomya albiceps (Wiedemann and Hemilucilia segmentaria (Fabricius (Diptera, Calliphoridae used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil. The corpse of a man was found in a Brazilian highland savanna (cerrado in the state of Minas Gerais. Fly larvae were collected at the crime scene and arrived at the laboratory three days afterwards. From the eight pre-pupae, seven adults of Chrysomya albiceps (Wiedemann, 1819 emerged and, from the two larvae, two adults of Hemilucilia segmentaria (Fabricius, 1805 were obtained. As necrophagous insects use corpses as a feeding resource, their development rate can be used as a tool to estimate the postmortem interval. The post-embryonary development stage of the immature collected on the body was estimated as the difference between the total development time and the time required for them to become adults in the lab. The estimated age of the maggots from both species and the minimum postmortem interval were four days. This is the first time that H. segmentaria is used to estimate the postmortem interval in a forensic case.

Full Text Available O objetivo desse estudo foi quantificar o ganho genético para produtividade de grãos do programa de melhoramento do arroz irrigado de Minas Gerais, no período de 1998 a 2010. Foram utilizados dados dos ensaios comparativos avançados realizados em quatro localidades diferentes de Minas Gerais. Nem todos os locais foram contemplados em todos os anos agrícolas e para estimativas com maior acurácia, utilizou-se o método de modelos mistos. O ganho genético para produtividade de grãos no período considerado foi de 107,42 kg ha-1, o que representou uma proporção de 17,88% da estimativa total do progresso. Esse ganho correspondeu ao aumento de 8,95 kg ha-1 ano-1, ou ainda, aumento de 1,99% em produtividade de grãos por ano. Apesar de o ganho genético ter sido satisfatório, novas alternativas de melhoramento podem ser empreendidas para que o incremento produtivo seja maior nos próximos anos.

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

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

No entanto, as parametrizações deste modelo, hoje disponíveis, produzem resultados subestimados quando aplicadas à região do Cerrado de Minas Gerais. Dessa forma, o objetivo deste trabalho foi parametrizar o modelo 3-PG para plantios de eucalipto localizados na região do Cerrado de Minas Gerais. Para isso, foram utilizados dados de povoamentos de híbridos clonais de Eucalyptus grandis x Eucalyptus urophylla, com idades entre 3 e 84 meses, localizados nas regiões de Curvelo e Itacambira  – MG. As estimativas de crescimento obtidas pelo modelo 3-PG foram comparadas com dados de crescimento de povoamentos florestais medidos nas duas regiões, até a idade de 84 meses. O conjunto de valores de parâmetros e variáveis obtidos neste trabalho permitiu simular com acurácia, em termos das variáveis produzidas pelo modelo, os padrões de crescimento de povoamentos florestais presentes na região do Cerrado mineiro. Dessa forma, conclui-se que a parametrização promoveu melhorias no desempenho do modelo que resultaram em estimativas acuradas de crescimento.

Nas condições atuais, o grau de evolução química e mineralógica é moderado em relação ao desenvolvido sobre outros tipos de rochas básicas e ultrabásicas da mesma área, caracterizando-se por uma importante perda de Na e Mg e, em menor proporção, de Ca e Si. O Al (localmente também o Fe é o elemento menos móvel dos sistemas. O K é escasso no material de origem e nas zonas de alteração, e ocorre enriquecimento desse elemento nos horizontes superficiais por aporte externo. Os minerais primários mais facilmente intemperizáveis, como o talco, a tremolita e a clorita trioctaédrica, são abundantes ainda na fração argila desses solos tropicais com composição mineralógica pouco comum, mas são todos termodinamicamente instáveis. Do ponto de vista geoquímico, o processo de alteração atual pode ser definido como uma bissialitização, que pode coincidir com ferruginização, com formação de minerais trioctaédricos secundários por transformação direta de estrutura e também por neoformação, todos coexistindo com os minerais primários residuais. No entanto, as fases de maior evolução, em volumes com drenagem mais eficiente, tendem à monossialitização, com formação de caulinitas de diferentes graus de cristalinidade.

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.

Foi também aplicado questionário a professores para avaliar o ensino desta temática, além de trabalho de campo, com aplicação de questionário estruturado a um grupo de alunos, em duas destas escolas, para aprofundamento do estudo, em dois momentos distintos da formação dos alunos, o que permitiu uma discussão crítica e transversal da formação acadêmica. Os resultados mostraram que o conhecimento de bioética com ênfase em cuidados paliativos e com a formação de médicos que atendam às necessidades emergentes desta área da saúde não está suficientemente contemplado nas escolas médicas do Estado de Minas Gerais, assim como não se observa uma correlação entre o ensino de bioética e o ensino de cuidados paliativos. Propõe-se uma reflexão e uma ação programática para a formação docente e subsequente inserção curricular específica e de caráter longitudinal do ensino de bioética e cuidados paliativos nos cursos de graduação das escolas médicas de Minas Gerais.

Full Text Available This paper analyses the representations of childhood by women of rural communities from the state of Minas Gerais, in the first half of the 20th century, who have migrated to Belo Horizonte as adults and live in a suburban area of the Minas Gerais capital. We interviewed 13 women, and gathered demographic data and educational legislation of that period. During the interviews, the recurrent statement “I had no childhood” can be understood as a contraposition made by them between a supposed ideal childhood, related to socially privileged classes, and childhood nowadays, the one they were excluded from. The evoked memories refer to the intense work routine in the field and in other people’s houses, the hardships to frequent a school, the poor state of the clothes, the lack of toys, but also the joyful moments of games and the participation on religious celebrations. Family, work and religion compete with the school as important spaces of sociability.

Full Text Available This article shows the economic significance of the group of mines that belonged to the jurisdiction of the «Caja de Guadalajara». The novelty lies in that local historiography had erroneously labeled these mining camps as being small. Recent studies show that they were not so small after all. These groups of mines were the focal point of the economy of a vast region and triggered the development of agriculture, livestock and trade activities. This article reveals the nexus between the fluctuations in silver production and events in Europe.

Full Text Available Parasite related problems are considered one of the major health problems for sheep breeding, causing considerable economic losses to commercial husbandry. The aim of this study was to determine the technological level and the level of knowledge of farmers regarding management practices to control gastrointestinal parasites in sheep in Minas Gerais state, southeastern Brazil. The analysis was based on 213 questionnaires applied by official veterinarians of the State Government Agency for Animal Health (Instituto Mineiro de Agropecuária, IMA, covering 16.6% of all counties. From two hundred and thirteen sheep farms sampled, 117 farms had their technological level determined. From the samples, 0.9% were characterized as high level, 45.3% as medium, and 53.0% as low technological level. The flock size ranged from 2 to 1843 with an average of 80.5 sheep per farm. The majority of the sheep production systems was extensive/semi-extensive (74.5%. The management practices adopted by the farmers to reduce parasitism were: split young and adult animals (5.6%, change pasture after deworm the animals (5.2%, use quarantine for incoming animals (2.3%, deworm newly arrived sheep (1.5%, and have regular technical assistance (31.9%. Although 76.5% of the farmers medicate the animals, treatments were performed without any major technical criteria, with an average interval of 4.6 months. The most commonly used drug families were macrocyclic lactones (38.5% and benzimidazoles (24.9%. The management practices adopted in Minas Gerais are based on old recommendations and may not return in a good set of strategies to prevent parasite infections. Field observations reinforce the finding where farmers have obtained unsatisfactory results in maintaining the health and productivity level of their enterprises.Problemas relacionados com parasitas são considerados um dos principais problemas sanitários na criação de ovinos, causando consideráveis perdas econômicas para

Full Text Available A erosão hídrica é um dos principais processos associados à degradação ambiental, sendo a desagregação e o transporte das partículas do solo decorrentes, principalmente, da energia cinética proveniente do impacto das gotas da chuva sobre o solo e do escoamento superficial. Tendo em vista as perdas na produção agrícola resultantes da erosão hídrica, aliadas ao alto custo de adoção e manutenção de sistemas de conservação de solos, é fundamental que estes sejam instalados de maneira adequada. Visando otimizar o projeto e adotar sistemas de conservação de solos, Pruski e colaboradores desenvolveram um modelo com vistas em obter a lâmina máxima de escoamento superficial em condições típicas de áreas agrícolas. Neste trabalho, procedeu-se à avaliação deste modelo pela comparação dos valores calculados com os obtidos experimentalmente, tendo-se evidenciado pequenas diferenças percentuais e altos coeficientes de correlação entre os valores obtidos experimentalmente e os calculados. Esses valores indicam que o modelo avaliado mostra-se eficiente para prever a lâmina máxima de escoamento superficial.

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.

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 This article discusses some facts that determined the remuneration of the male and female teacher of primary school in Minas Gerais province/state during the second half of XIX century. It shows that the remuneration was paid according to different criteria as the sex of the teacher; function position – effective, substitute, for example –, the localization of the school – rural, urbane, district or village –, the teaching position in which the male and female teacher worked, how long he/she was teaching, the number of the students in the class and others. Summary, the remuneration can be analyzed as a result of historical values that have been constructed inside the school and public sphere, and in the social relations outside them.

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

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 Conduziu-se este trabalho, com o objetivo de proceder à análise crítica do Programa de melhoramento genético do feijoeiro comum em Minas Gerais nos últimos 32 anos com ênfase nas implicações da interação linhagens x ambientes, além de avaliar se houve progresso genético. Para isso, foram utilizados dados de 169 experimentos conduzidos no período de 1974 a 2004 e que envolveram 16 locais e três safras. A média da cultivar Carioca, comum em todos os experimentos, foi utilizada como estimador do efeito ambiental e a média das cinco melhores linhagens sob avaliação de cada biênio, como efeito fenotípico. A diferença entre essas duas médias forneceu o desvio genético. O coeficiente de regressão linear entre desvio genético Y (variável dependente e o biênio X (variável independente forneceu a estimativa do progresso genético. As interações linhagens x safras e linhagens x anos foram, na maioria dos casos, significativas, contudo, suas contribuições para a variação total foram inferiores a de linhagens x locais. Desse modo, fica clara a necessidade de que os experimentos sejam conduzidos em um maior número de locais.
