A participa??o de Produtores Rurais (PR) tem se destacado nos ?ltimos anos e socializa uma atividade ent?o praticada predominantemente por grandes empresas florestais, fato este que suporta a escassez de trabalhos direcionados para produ??o em menor escala. Este estudo objetivou avaliar as pr?ticas de silvicultura empregadas pelos PR tendo como refer?ncia as pr?ticas adotadas por uma empresa que utiliza em seus plantios as melhores tecnologias silviculturais; estimar os custos de forma??o e condu??o de florestas conforme os procedimentos empregados pelos produtores em rela??o a diferentes op??es tecnol?gicas; e analisar o retorno de investimentos estimados sob crit?rios econ?micos. A popula??o abrangida neste estudo correspondeu a 583 PR do Alto Jequitinhonha que apresentaram Declara??es de Colheita e Comercializa??o no Instituto Estadual de Florestas entre janeiro de 2008 e outubro de 2009. Neste universo, 71 PR foram escolhidos aleatoriamente para responder um formul?rio com perguntas que abordaram a origem do material gen?tico, espa?amento, rota??o, todas as pr?ticas de silvicultura, a colheita e comercializa??o da madeira adotada. Estas mesmas vari?veis foram avaliadas em uma grande empresa florestal instalada na regi?o que trabalha com as melhores pr?ticas silviculturais. Ap?s obtidos, os dados foram analisados pela estat?stica descritiva. Os PR do Alto Jequitinhonha t?m significativa ?rea plantada com Eucalyptus urophylla e E. cloesiana, entretanto a tecnologia de silvicultura adotada ? obsoleta em rela??o ?s tecnologias empregadas por grandes empresas. Consequentemente, reduzem-se o potencial produtivo dos s?tios florestais e o retorno econ?mico. De forma geral a madeira de eucalipto ? direcionada para produ??o de carv?o vegetal. A tecnologia utilizada pelos produtores rurais na regi?o de estudo n?o ofereceu os melhores resultados econ?micos em qualquer dos cen?rios de pre?os estudados quando comparadas com a tecnologia utilizada pela empresa que utiliza elevado n?vel tecnol?gico. Devido ?s suas propriedades tecnol?gicas e ao uso pelo mercado madeireiro, a melhor viabilidade econ?mica para a madeira do E. cloesiana ? sua comercializa??o para a produ??o de postes de cerca, mour?es e para a constru??o civil. / Disserta??o (Mestrado) ?

The participation of farmers has been prominent in recent years, increasing the social benefits of eucalyptus plantation, as it had been traditionally planted by large forest companies so far. This study aimed to evaluate the forestry practices employed by these farmers in comparison to the best practices adopted by traditional companies, by estimating cost x benefit relation of forestry as a complementary business, based on the procedures carried out by these farmers under different technological options. The population covered by this study was represented by 583 farmers from Alto Jequitinhonha, who registered a document called ?Harvest statement?, as required by the state agency ?Instituto Estadual de Florestas?, between January 2008 and October 2009. From these, 71 farmers were randomly selected to answer a questionnaire addressing data such as the origin of species, spacing, rotation, the main silvicultural practices, harvesting and commercialization strategies employed. The same variables from a large regional forestry company were evaluated and used as reference. Data collected was analyzed by using descriptive statistics. It was found that farmers of Alto Jequitinhonha owns a very significant planted area with Eucalyptus urophylla and E. Cloesiana, although they employ much lower technological level in comparison to the technologies used by the large company. In consequence, the potential yield in these sites is reduced. In general, the eucalyptus wood is intended for charcoal production. The technology used by farmers in the study area did not offer the best economic results in any of the price scenarios studied, when compared to the company used as reference. E. cloesiana showed a better economic return, due to its technological properties and better acceptance into the local market, for lamp posts, fence posts and overall use in civil construction.

Foi instalado um experimento em ?reas da empresa APERAM BIOENERGIA, no munic?pio de Itamarandiba - MG, utilizando o delineamento experimental, blocos ao acaso. As parcelas foram constitu?das por cinco espa?amentos iniciais de plantio (3,0 x 0,5 m; 3,0 x 1,0 m; 3,0 x 1,5 m; 3,0 x 2,0 m e 3,0 x 3,0 m) e as ?pocas de medi??o ocorreram aos 7, 12, 18, 24, 48, 61, 77, 85 e 102 meses.

The experiment was performed in areas of the company APERAM BIOENERGIA in the city of Itamarandiba, MG, using a randomized block design. The plots consisted of five spacing initial (3.0 x 0.5 m, 3.0 x 1.0 m, 3.0 x 1.5 m, 3.0 and 3.0 x 2.0 x 3.0 m) and measurements were performed at 7, 12, 18, ??24, 48, 61, 77, 85 and 102 months. From the information collected in the field were estimated for each treatment the volume and biomass per hectare, density, calorific value, and other dendrometric variable and stand variables. It was found that the spacing and age influence significant on the values ??of average diameter, height total, basal area, volume total per hectare, biomass per hectare, density and calorific value. The growth in volume per hectare in the biomass per hectare and basal area per hectare was directly related to planting density, and the higher values ??for the smaller spacing. On the other hand the average diameter and total height of the trees were negatively correlated with the density. The specific gravity tends to increase with age and with the spacing of the trees. And the calorific value tends to rise with age and with the planting spacing. The spacing did not influence the survival rate of trees. The technique rotation and economic rotation occurred earlier in smaller plantings spaced. For all spacing the technique age cutting was higher than the economic age cutting. The spacing of 3.0 x 1.5 proved to be a more attractive option according to the criteria net present value and equivalent periodic benefit, considering the sale of standing timber.

Data from 14,288 animals born from 1990 to 2005 were submitted to PCA aimed at reducing the dimensionality of the data set. There had been considered the following characteristics: height at withers, height at croup, lengths of head, neck, back, croup, hip length and body, widths of head, hip width, thorax perimeter, cannon bone circumference and marcha score. From this analysis, it was suggested seven variables to be discarded, because they have higher weightings (eigenvectors) in absolute value from the last major component. Based on the results, there was recommended the following characteristics to be maintained in future work: marcha score, height at croup, length of back, length of croup, width of head and cannon bone circumference. In a second step, these features were subjected to a genetic analysis to estimate their heritability?s and genetic and phenotypic correlations. The components of (co) variance needed to estimate the genetic parameters studied were estimated by Restricted Maximum Likelihood (REML). The trait animal model included direct genetic effect as random and fixed effects of contemporary groups and the covariate age record. High heritability estimates were found, suggesting the possibility of direct response to selection. Genetic and phenotypic correlation were estimate of absence to moderate magnitudes between traits and observed discrete genetic trends over the years for most traits.

This study aimed to expand the knowledge on the effect of the systems to maternity and heating of creep for piglets using the image analysis as evaluation tool to understand animal behavior, to evaluate some of the indexes of both piglets and the females considering that it can be influenced by environment and allow an economic analysis of this systems. There were evaluated two types of dam cells and two types of creep. The model 1 (MOD 1) was formed by 8 dam cells with semi-slatted floor and creep of masonry, with electrical resistance built into the floor and illumination with fluorescent lamp of 7 W. The model 2 (MOD 2) consisted of eight dam cells with totally ripped iron, with the creep of wood for heating by incandescent lamp of 60W. Data were collected from birth until weaning at 21 days. The MOD 1 showed the best performance values for piglets. The temperature of the creep of MOD 1 showed the highest percentage of temperatures within the thermal comfort in relation to MOD 2, despite the high percentage of temperature below comfort. The temperature of the floor of MOD 1 showed the highest percentage of values within the thermal comfort in every week of the experimental period. The temperature of the surface of the cells in MOD 1 were higher compared to the MOD 2, but not enough to cause thermal discomfort for the sows. The hygiene of the cells was not affected directly by the structure of the cell but rather by changes in handling practices such as feeding on different time than usual. Mortality, omphalitis, arthritis and knee injuries of the piglets showed no significant differences between the systems (p<0.05). The use of the system with creep with heated floors (MOD 1) showed a profit above the heating system with a light bulb (MOD 2) of approximately R$ 1,37 for litter, being necessary the evaluation of the expends to infer about the most financially profitable system for the producer.

We evaluated 45 male weanling Guzer?, with initial average weight and age and standard deviation of 219.9 ? 38.05 kg and 325.8 ? 28.0 days, respectively. At trial, the animals were grazing Brachiaria brizantha and supplementation multiple received sanitary treatment and were maintained under uniform management for a period of 294 days. The evaluations took place every 56 days. From this PGP sought to evaluate a nonlinear function that best describe the growth curve of animals, estimate the relative development of the loin eye area measured by ultrasound, scrotal circumference and morphometric measurements in relation to body weight bovine Guzera through the study of allometric growth, was also evaluated a set of features through principal component analysis, to identify the characteristics that represent most of the phenotypic variation. The characteristics evaluated by principal components were: weight at 205 days (P205), weight at 365 days (P365), weight at 550 days (P550), average weight gain (ADG), scrotal circumference (SC), hip height (HG), body length (CC), thoracic circumference (TC), loin eye area (LEA), structure (E), precocity (P) and muscle (M). In this study, the Von Bertalanffy function was the best fit to describe the growth of males Guzera grazing on PGP, as the allometric growth presented heterogonic negative for all traits in relation to body weight. In this study, the Von Bertalanffy function was the best fit to describe the growth of males Guzera grazing on PGP, as the allometric growth presented heterogonic negative for all traits in relation to body weight. As for principal components analysis the first three principal components explained 74.51% of the total variation of data, which are associated with larger eigenvalues and thus retaining, greater data variance. The characters with the highest participation in these components were P205, P and M.

Qualidade da ?gua para Consumo Humano no munic?pio de Diamantina, Minas Gerais, identificar as formas de abastecimento de ?gua no munic?pio, diagnosticar as condi??es s?cio sanit?rias e o conhecimento das pessoas sobre a qualidade da ?gua consumida no distrito de Sopa. Ainda, objetivou georreferenciar as fontes alternativas de ?gua no cen?rio escolhido (Sopa) bem como analisar a qualidade microbiol?gica (coliformes totais e Escherichia coli) da ?gua consumida. Foram entrevistados os gestores do Programa e a popula??o residente no distrito de Sopa, por meio de question?rios estruturados. Elaborou-se mapa com a identifica??o georreferenciada das fontes alternativas utilizadas nas localidades rurais. Verificou-se que o programa Vigi?gua encontra-se implantado de forma incipiente no munic?pio e com poucas a??es de monitoramento e vigil?ncia da qualidade da ?gua. O distrito estudado apresenta condi??es de saneamento b?sico insatisfat?rias, uma vez que n?o possui rede de esgotamento sanit?rio, coleta regular de res?duos s?lidos e apresenta abastecimento de ?gua por rede de distribui??o somente na ?rea urbana. Identificou-se que a popula??o rural est? sujeita a consumir ?gua com qualidade sanit?ria duvidosa. As an?lises microbiol?gicas realizadas no sistema de distribui??o que abastece a sede do distrito estavam em conformidade com os padr?es de potabilidade estabelecidos na legisla??o, mas a qualidade da ?gua de todas as fontes alternativas pesquisadas apresentou contamina??o por coliformes totais e E. coli. Portanto, espera-se que o mapa contribua e auxilie com a identifica??o das fontes alternativas utilizadas pela popula??o, para que se tornem alvo de a??es da vigil?ncia da qualidade da ?gua. Faz se necess?rio e imprescind?vel a articula??o intersetorial para a execu??o e implementa??o efetiva do Programa Vigi?gua no munic?pio. / Disserta??o (Mestrado Profissional) ?

It takes aim at the ways used for the water supply in the municipality, to diagnose the social and sanitary conditions and also about the acquaintance the inhabitants have about that water consumed in the district of Sopa. Even so, is the aim to georreference the alternative sources of water supply for consumption in that chosen spot (Sopa) as well to analyze the microbiological quality (Total Coliforms and Escherichia coli) from the consumed water. The managers of the program and the residing population in the district of Sopa were means of a structural questionnaire. A map with a georeficiated identification of the alternative sources utilized in those rural villages was made. It has been remarked that the mentioned Vigi?gua program is actually implanted under an incipient way in that municipality with no suitable monitoring and vigilance actions concerning to the quality of the water. The above mentioned district presents no satisfactory conditions of basic drainage, since it does not process sanitary draining, a regular collect of solid residues and presents the water supply by a distribution network restricted to the urban area. It was identified that the rural population is subject to consume water a doubtful sanitary quality. The microbiological analysis accomplished in the distribution system that supplies the seat of the municipality were according to the standards of potability legally establised, but the water quality from all alternatives sources research presented a contamination by Total Coliforms and E. coli. Therefore it is expected the map can contribute and help in the identification of the alternative sources utilized by the population to be a target of actions in the vigilance of water quality. It is necessary the intersectional articulation to the effective implement of the Vigi?gua Program in that municipality.

No munic?pio com maior ocorr?ncia da LV humana, realizou-se o georreferenciamento dos casos humanos e caninos associados a fatores ambientais e sociais; analisou-se a percep??o das pessoas acometidas pela doen?a por meio de entrevistas; aspectos da estrutura e funcionamento do servi?o de controle da doen?a foram analisados por meio de question?rios. No per?odo de 2007 a 2012 houve a notifica??o de 79 casos de LV humana e 451 c?es positivos para a infec??o canina nos munic?pios que comp?em a SRSD. Nestes, a LV humana foi mais prevalente em crian?as, pessoas do g?nero masculino e residentes em ?reas rurais. Em Ara?ua?, munic?pio com maior transmiss?o da LV humana, houve a notifica??o de 41 casos de LV entre os anos de 2007 a 2013. Neste, a infec??o acometeu principalmente crian?as, pessoas do g?nero masculino e residentes da ?rea urbana. A distribui??o espacial dos casos de LV humana e da infec??o canina na ?rea urbana do munic?pio de Ara?ua? exibiu um padr?o aglomerado, com agrupamentos de casos humanos estatisticamente significativos a dist?ncias superiores a 350 metros e agrupamentos estatisticamente significativos de c?es infectados a dist?ncias superiores a 75 metros. A an?lise explorat?ria por meio do estimador de Kernel apontou para maior ocorr?ncia de casos humanos e caninos na ?rea central da cidade. N?o foi observada rela??o entre o ?ndice de Vegeta??o da Diferen?a Normalizada e as ?reas de maior ocorr?ncia da doen?a. A an?lise socioambiental dos ambientes domiciliares das pessoas acometidas pela LV no munic?pio de Ara?ua? revelou um predom?nio de defici?ncias em estruturas de saneamento ambiental; presen?a de arbustos, ?rvores frut?feras e diferentes animais ao redor dos domic?lios; proximidade com ambientes naturais e casas aglomeradas. Por meio das entrevistas com as pessoas que foram acometidas pela LV, foi poss?vel perceber um desconhecimento em rela??o ? doen?a, principalmente no que diz respeito ?s formas de transmiss?o. P?de-se perceber tamb?m que os m?dicos tiveram dificuldade em diagnosticar a LV e que o tratamento que estes prescreveram para os pacientes foi, no geral, demorado. De forma geral, o munic?pio de Ara?ua? desenvolve a maioria das a??es propostas pelo Minist?rio da Sa?de para o Programa de Controle da Leishmaniose Visceral (PCLV), contudo, h? necessidade de melhor estrutura??o do servi?o de controle da LV neste. A realiza??o de planejamentos para os levantamentos das demandas de materiais para a execu??o dos diagn?sticos da LV para que n?o os falte durante a realiza??o dos inqu?ritos e o estabelecimento de condi??es para a execu??o de levantamentos entomol?gicos ? uma necessidade premente. O investimento em trabalhos de educa??o em sa?de para a popula??o, educa??o continuada para os m?dicos, Agentes de Combate a Endemias e demais profissionais envolvidos no PCLV tamb?m ? fundamental. / Disserta??o (Mestrado Profissional) ?

In the city with the highest occurrence of human VL was held georeferencing of human and canine cases associated with environmental and social factors; analyzed the perception of people with the disease through interviews; aspects of the structure and function of disease control service were analyzed by means of questionnaires. In the period 2007-2012 there was a notification of 79 cases of human VL and 451 dogs positive for canine infection in the municipalities that make up the SRSD. In these, the human VL was more prevalent in children, male gender and living people in rural areas. In Ara?ua?, municipality with greater transmission of human VL, there was notification of 41 cases of VL between the years 2007 to 2013. In this, the infection affected mainly children, males and gender residents of the urban area. The spatial distribution of cases of human VL and canine infection in urban Ara?ua? municipality exhibited a pattern crowded with groups of statistically significant human cases at distances greater than 350 meters and statistically significant clusters of infected dogs at distances greater than 75 meters . The exploratory analysis using the Kernel estimator pointed to a higher incidence of human and canine cases in the central area of the city. No relationship was found between the Difference Vegetation Index Normalized and areas of highest incidence of the disease. The environmental analysis of the home environments of people affected by LV in the municipality of Ara?ua? revealed a predominance of deficiencies in environmental sanitation structures; presence of shrubs, fruit trees and different animals around the household; proximity to natural environments and clustered houses. Through interviews with people who have been affected by LV, it was revealed an ignorance about the disease, particularly with regard to forms of transmission. It could be perceived also that doctors had difficulty diagnosing VL and the treatment prescribed for these patients was generally, time consuming. In general, the municipality of Ara?ua? develop most of the actions proposed by the Ministry of Health for the Control Program Visceral Leishmaniasis (PCLV), however, there is need for a better structuring of the LV control this service. The realization of plans for surveys of the demands of materials for the execution of LV diagnostics lest they miss during the surveys and the establishment of conditions for the implementation of entomological surveys is urgently needed. Investment in health education work for the population, continuing education for physicians, Fighting Endemic Diseases agents and other professionals involved in PCLV is also key.

De uma forma geral, sua ocorr?ncia est? associada a grupos sociais vulner?veis vivendo em ?reas deficit?rias em servi?os de saneamento ambiental e a padr?es de comportamento da popula??o. Al?m disso, altera??es promovidas no ambiente por atividades humanas em diferentes contextos, sobretudo aquelas que afetam diretamente as cole??es h?dricas podem favorecer a instala??o ou manuten??o de focos da doen?a. Desta forma, o presente estudo objetivou analisar os fatores ambientais e sociais associados ? din?mica de ocorr?ncia da esquistossomose no munic?pio de Serro, estado de Minas Gerais. Para tanto, conduziu-se estudo epidemiol?gico, de car?ter descritivo e quantitativo dos casos de esquistossomose ocorridos no per?odo 2010-2014, a partir de dados levantados junto ao Programa de Controle da Esquistossomose de Serro e de entrevistas com a popula??o. Foram identificados 352 casos diagnosticados no per?odo considerado, dentre os quais 104 participaram das entrevistas. Da popula??o total afetada, observou-se ser esta predominantemente masculina (62,78%), em idade economicamente ativa de 15-59 anos (80,1%), com ensino fundamental incompleto (52,8%) e residindo na ?rea rural (81,5%). Dentre os entrevistados, a maioria era natural do pr?prio munic?pio (84,7%), morando na atual resid?ncia h? mais de 20 anos (70%) na qual convivem de 3-6 pessoas (65,4%). A principal forma de ocupa??o s?o as atividades agropecu?rias (48,1%), com a maioria mantendo h?bito regular de fazer exames e consultas m?dicas (62,5%). A maior parte faz uso de ?gua proveniente de nascentes (56,7%) e consideram a ?gua consumida nas casas de boa qualidade (86,5%). A maioria das moradias possui banheiro com vaso sanit?rio (79,8%) destinando o esgoto para fossas secas no quintal ou rede de esgoto da rua (73,1%). ? expressivo o n?mero daqueles que declararam frequentar semanal (90,4%) ou quinzenalmente (79,7%) rios, ribeir?es e c?rregos (74,5%), cachoeiras (13,8%) e a?udes (9,6%) na regi?o, na maioria das vezes mantendo contato com as ?guas para pescar (55,3%), nadar (56,6%) e fazer travessia de caminho (41,5%). A maioria dos entrevistados declarou ter alguma informa??o sobre a doen?a antes de ser diagnosticado infectado (81,7%) e 62,5% n?o retornaram aos servi?os de sa?de para realizar o exame ap?s tratamento medicamentoso. A distribui??o da esquistossomose no munic?pio de Serro esteve significativamente agregada na por??o leste do munic?pio, em ?reas com menor varia??o na eleva??o e declividade, maiores ?ndice de vegeta??o e umidade, associada a ?reas com maior propor??o de domic?lios cujo esgotamento sanit?rio ocorria diretamente em cursos d??gua. Observou-se, ainda, que o maior n?mero de casos da doen?a ocorreu em localidades drenadas por rios da bacia hidrogr?fica do Rio Doce. Diante das particularidades apresentadas na extens?o do munic?pio, principalmente em rela??o ? espacializa??o da doen?a entre as duas grandes bacias hidrogr?ficas do munic?pio (Jequitinhonha e Rio Doce), as informa??es apresentadas podem contribuir para o direcionamento das a??es de controle na escala municipal, seja por meio de estrutura??o sanit?ria e ambiental, ou por meio de orienta??es quanto ao comportamento e exposi??o ?s cole??es h?dricas eventualmente contaminadas por parte da popula??o. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Sa?de, Sociedade e Ambiente, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2016. / Schistosomiasis is an neglected tropical disease that affects annually millions of people worldwide. It is caused by Schistosoma mansoni worm that besides the definitive host, depends on the aquatic environment and on the Biomphalaria snails as an intermediate host to complete its life cycle. In general, its occurrence is associated with vulnerable groups living in areas where the environmental sanitation services are deficient and also associated to the population behavior patterns. In addition, changes introduced into the environment by human activities in different contexts, especially those that directly affect the water sources may promote the installation or maintenance of the disease outbreaks. Thus, this study aimed to analyze the environmental and social factors associated with the dynamics of Schistosomiasis occurrence in the city of Serro, Minas Gerais. For this it was conducted an epidemiological study, descriptive and quantitative of the Schistosomiasis cases occurred in the period 2010- 2014, from the data collected by the Schistosomiasis Control Program of Serro and interviews with the population. It was identified 352 diagnosed cases in the considered period, among which 104 participated in the interviews. Considering the total affected population, it was observed the predominance of men (62.78%), in work age of 15-59 years old (80.1%), with incomplete primary education (52.8%) and living in rural areas (81.5%). Among the respondents, most were natural of the municipality (84.7%), living at the current residence for more than 20 years (70%) living together with 3-6 people (65.4%). The main form of occupation is agricultural activities (48.1%), and most of them maintain regular habits of doing exams and having medical appointments (62.5%). Most of the respondents makes use of water coming from springs (56.7%) and consider the water consumed in their houses of good quality (86.5%). Most of the houses have bathroom with toilet (79.8%) intended for dry sewage tanks in the yard or street sewer network (73.1%). It is significant the number of those who reported that go to weekly (90.4%)or once every two weeks (79.7%) rivers, brooks and streams (74.5%), waterfalls (13.8%) and dams (9.6%) in the region, most of the time having contact with the water to fish (55.3%), to swimming (56.6%) and to crossing the path (41.5%). Most respondents claimed to have some information about the disease before being diagnosed infected (81.7%) and 62.5% did not return to health services for the exam after drug treatment. The distribution of Schistosomiasis in Serro municipality was significantly aggregated in the eastern portion of the city, in areas with less variation in elevation and slope, the largest index of vegetation and moisture associated with areas with the highest proportion of households where the sewage occurred directly into the watercourses. It was also noted that the highest number of cases of the disease occurred in places drained by rivers of the Rio Doce basin. Given the particularities presented at the county extension, especially in relation to the spatial distribution of the disease between two large municipal watersheds (Jequitinhonha and Rio Doce), the information presented may contribute to the guidance of the control actions on municipal level, either through health and environmental structuring, or through guidelines on the behavior and exposure to possibly contaminated water sources by the population.

Uma dessas s?o os res?duos agr?colas, como as tortas, coprodutos de processos de extra??o mec?nica de ?leos de frutos, sementes e cereais (oleaginosas), que representam um desafio por muitas vezes n?o possu?rem um destino vi?vel ou at? rent?vel que atenda as exig?ncias ambientais. Um desses ? o buriti (Mauritia flexuosa L.), fonte de um ?leo com alto teor de caroten?ides representando, assim, aplica??es em ind?strias aliment?cias, cosm?ticas e farmacol?gicas e resultando em ac?mulo de seu material. O trabalho foi desenvolvido a partir da torta de buriti obtida ap?s extra??o mec?nica de seu ?leo. Foi verificado que a torta ? constitu?da por aproximadamente 44% de sua massa por carboidratos livres ou polimerizados. Foram realizados tratamentos qu?micos com solu??es de ?cido dilu?do e base em duas etapas distintas, a fim de promover a remo??o da hemicelulose e lignina. Por fim, foi feita a hidr?lise com complexo enzim?tico de celulases, enzimas que hidrolisam cadeias celul?sicas em monossacar?deos de glicose, substrato utilizado por microrganismos como a levedura Saccharomyces cerevisiae no metabolismo celular, tendo como produto excretado o etanol. Ap?s a hidr?lise enzim?tica, obteve teores de 53,58% (m/m) de glicose liberada do farelo tratado, apresentando um rendimento em torno de 60% (m/m). Com a fermenta??o do hidrolisado, obtido ap?s o tratamento enzim?tico, foi verificada a obten??o de etanol em rendimento (fator de convers?o de substrato em produto, Yp/s) de 0,43 em rela??o ? quantidade de substrato utiliza??o na hidr?lise enzim?tica. O produto obtido foi analisado em cromat?grafo a g?s acoplado ao espectr?metro de massa, confirmando a obten??o de bioetanol. Al?m disso, foram realizadas medidas de microscopia eletr?nica por varredura e difratometria de raios-X, verificando altera??es na estrutura f?sica e morfol?gica do material ao longo do processo.

One of these are agriculture residues, such as pies, co-products of mechanical extraction processes of fruit oils, seeds and cereals (oil), which represent a challenge in many times do not possess a viable or even profitable destination that meets the environmental requirements. One of these is the buriti (Mauritia flexuosa L.), source of a oil with high content of carotenes, representing thus, applications in food industries, cosmetic and pharmaceutical, resulting in accumulation of its material. The work was developed from the buriti pie obtained after mechanical extraction of its oil. It was verified that the pie is comprise by approximately 44% of its mass by free carbohydrates or polymerized. Chemical treatments were performed with dilute acid solutions and base in two distinct steps in order to promote the removal of hemicellulose and lignin. Finally, the hydrolysis was done with the enzyme complex of cellulases, enzymes that hydrolyze cellulose chains in monosaccharide glucose, a substrate used by microorganisms such as Saccharomyces cerevisiae yeast in cell metabolism, with ethanol as the product excreted . After enzymatic hydrolysis, it was obtained content of 53.58% (m/m) of glucose released from the treated bran, showing a yield around 60% (m/m). With the fermentation of the hydrolyzate obtained after the enzymatic treatment was verified obtaining of ethanol in yield (substrate conversion factor in product, Yp / s) of 0.43 compared to the amount of substrate used in the enzymatic hydrolysis. The obtained product was analyzed in a gas chromatograph coupled to a mass spectrometer, confirming obtaining bioethanol. In addition, were carried out measures of scanning electron microscopy and X-ray diffraction, checking changes in physical and morphological structure of the material throughout the process.

Os dados foram analisados mediante a utiliza??o das informa??es dispon?veis no Sistema de Informa??o de Agravos de Notifica??o (SINAN), Instituto Brasileiro de Geografia e Estat?stica (IBGE), Empresa de Assist?ncia T?cnica e Extens?o Rural do Estado Minas Gerais (EMATER) e Instituto Nacional de Meteorologia (INMET). O estudo apresentou como objetivo geral tra?ar o perfil epidemiol?gico da dengue nos munic?pios de Buritizeiro - MG e Pirapora - MG, entre os anos de 2012 a 2015. Os objetivos espec?ficos foram: a) Investigar a incid?ncia de dengue nos munic?pios de Buritizeiro - MG e Pirapora - MG, entre os anos de 2012 a 2015; b) Quantificar os casos confirmados de dengue nos munic?pios segundo faixa et?ria, ra?a/cor, sexo e escolaridade; c) Verificar a distribui??o espacial dos casos de dengue nos munic?pios, comparando com dados de vari?veis ambientais; d) Conhecer o funcionamento estrutural dos munic?pios no que diz respeito ao enfrentamento da dengue, mediante an?lises dos Planos de Conting?ncia para o Controle da Dengue; e) Subsidiar as secretarias de sa?de dos munic?pios de Buritizeiro - MG e Pirapora - MG com informa??es ajustadas sobre a dengue. ? um estudo quantitativo, longitudinal, com an?lises descritivas e explorat?rias, com dados retrospectivos. No munic?pio de Buritizeiro - MG foram notificados 1.801 casos de dengue e confirmados 641, sendo o maior n?mero em indiv?duos pardos, do sexo feminino, com escolaridade ensino m?dio completo. J? no munic?pio de Pirapora - MG foram notificados 3.267casos e confirmados 1.977, sendo o maior n?mero em indiv?duos do sexo feminino, pardos, com escolaridade ensino m?dio completo. A infec??o ocorreu em todas as faixas et?rias, sendo mais frequentes em indiv?duos de 20 a 49 anos de idade. Os munic?pios de Buritizeiro - MG e Pirapora - MG apresentaram incid?ncias vari?veis durante o per?odo do estudo. O ?ndice de Moran n?o mostrou evid?ncias de agrega??o espacial (I = - 0,018 p = 0,421). A an?lise da incid?ncia da dengue em rela??o ?s ambientais n?o evidenciou correla??o estatisticamente significativa para qualquer das vari?veis (temperatura m?dia diurna: r = - 0,0591, p = 0,7268; temperatura m?dia noturna: r = 0,2126, p = 0,1938; NDVI: r = 0,0219, p = 0,8949). O presente estudo servir? de base para elabora??o de pol?ticas p?blicas regionalizadas visando ? conten??o da dengue na Regi?o de Sa?de de Pirapora, Minas Gerais. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Sa?de, Sociedade e Ambiente, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / Aiming to know the epidemiological aspects of dengue in the municipalities of Buritizeiro - MG and Pirapora - MG, which compose the Region of Health of Pirapora / MG, a study of the distribution of the disease in the population was carried out. Data was analyzed using the information available in the Notification of Injury Information System (SINAN), Brazilian Institute of Geography and Statistics (IBGE), Technical Assistance and Rural Extension Company of the State of Minas Gerais (EMATER) and the National Institute of Meteorology (INMET). The objective of the study was to establish the epidemiological profile of dengue in the municipalities of Buritizeiro - MG and Pirapora - MG between the years of 2012 and 2015. The specific objectives were: a) To investigate the incidence of dengue in the municipalities of Buritizeiro - MG and Pirapora - MG, between the years of 2012 to 2015; B) To quantify the confirmed cases of dengue in the municipalities according to age, race/color, sex and education; C) To verify the spatial distribution of the dengue cases in the municipalities, comparing with data of environmental variables; D) To know the structural functioning of the municipalities with regard to coping with dengue, through analysis of Contingency Plans for Dengue Control; E) Subsidize the health secretariats of the municipalities of Buritizeiro - MG and Pirapora - MG with adjusted information on dengue. It is a longitudinal, quantitative study with descriptive and exploratory analyzes, with retrospective data. In the municipality of Buritizeiro - MG, 1,801 cases of dengue fever were reported and 641 confirmed cases, the highest number in mixedrace individuals, females, with a high school education. In the municipality of Pirapora - MG, 3,267 cases were reported and 1,977 confirmed, with the highest number in females, pardos, with a high school education. The infection occurred in all age groups, being more frequent in individuals from 20 to 49 years of age. The municipalities of Buritizeiro - MG and Pirapora - MG presented variable incidences during the study period. The Moran index did not show evidence of spatial aggregation (I = - 0.018 p = 0.421). Dengue incidence was not statistically significant for any of the variables (mean daytime temperature: r = -0.0591, p = 0.7268, mean night temperature: r = 0.2126, p = 0, 1938; NDVI: r = 0.0219, p = 0.8949). The present study will serve as a basis for the elaboration of regionalized public policies aiming at the containment of dengue in the Health Region of Pirapora, Minas Gerais.
