No. of bitstreams: 1 lierciofeitalmottajr.pdf: 12311012 bytes, checksum: fed882b800dc53c0a497d3bda1094a0e (MD5) Previous issue date: 2017-10-27 / No presente trabalho, é realizada a aplicação do modelo de previsão de acidentes do Higway Safety Manual – HSM, publicado pela American Association of State Highway and Transportation Officials (AASTHO) no ano de 2010, à rodovia de mão dupla e pista simples, BR–116, que corta perímetros urbanos de cidades no segmento entre Caratinga e Leopoldina, Minas Gerais. Busca-se avaliar a pertinência de sua utilização como ferramenta de sistemas de gestão de segurança rodoviária. Foram coletados dados de acidentes ocorridos nos trechos de estudo referentes ao intervalo entre 2011-2015, dados sobre o volume de tráfego, além de dados geométricos da via e das suas características ambientais. Foram analisadas as aplicações do modelo em sua condição base, calibrada e refinada pelo método empírico de Bayes. Como resultado da aplicação na condição base observou-se uma discrepância entre os valores de acidentes ocorridos e previstos pelo modelo, inviabilizando a utilização direta desta aplicação. A aplicação do modelo calibrado apresentou resultados mais próximos aos reais valores de acidentes, porém ainda não sendo possível a sua utilização como modelo de previsão de acidentes. No entanto, os valores obtidos pela aplicação do modelo do HSM refinado pelo método empírico de Bayes aproximam-se de maneira satisfatória dos valores de acidentes reais ocorridos, permitindo agora a sua utilização como modelo de previsão de acidentes, tendo sua aplicação como ferramenta de sistemas de gestão de segurança rodoviária. Apesar de ainda serem necessários estudos para melhoria da calibração e da condição base, às características especificas presentes no ambiente do perímetro urbano cortado por rodovias, o modelo aplicado neste trabalho pode ser utilizado como modelo de previsão de acidentes para estes trechos. / In the present work, the Higway Safety Manual - HSM, published by the American Association of State Highway and Transportation Officials (AASTHO), is applied to the double-lane and single-lane highway BR-116, which cuts urban in the segment between Caratinga and Leopoldina, Minas Gerais. The aim of this study was to evaluate the pertinence of its use as a tool for road safety management systems. Data were collected on accidents occurring in the study sections referring to the interval between 2011-2015, data on traffic volume, as well as geometric data of the road and their environmental characteristics. The applications of the model were analyzed in their base condition, calibrated and refined by Bayes' empirical method. As a result of the application in the base condition it was observed a discrepancy between the values of accidents occurred and foreseen by the model, making it impossible to use this application directly. The application of the calibrated model presented results closer to the actual values of accidents, but it is not yet possible to use them as an accident prediction model. However, the values obtained by applying the HSM model refined by the empirical method of Bayes approach satisfactorily the values of real accidents occurred, allowing now its use as an accident prediction model, having its use as a tool of systems of road safety management. Although still necessary studies to improve the calibration and the base condition, to the specific characteristics present in the environment of the urban perimeter cut by highways, the model applied in this work can be used as a predictive model of accidents for these stretches.

AnÃlise da (Auto) Sustentabilidade do PerÃmetro Irrigado Baixo AcaraÃ: Um Estudo de Caso / Analysis of (auto) sustainability of the Baixo Acaraà Irrigation Perimeter: A Case Study

Josiane Aparecida de Lima Oliveira 30 May 2008 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Em vÃrias partes do territÃrio nacional pode-se perceber a preocupaÃÃo com a questÃo da insuficiÃncia de recursos hÃdricos, que se tornam mais escassos à medida que a populaÃÃo, a indÃstria e a agricultura se ampliam. No semi-Ãrido brasileiro, a questÃo à ainda mais delicada, pois hà a importante interferÃncia de fatores climÃticos, como ocorrÃncia de secas e irregular distribuiÃÃo de chuvas, que comprometem a disponibilidade de Ãgua. A utilizaÃÃo da irrigaÃÃo torna-se essencial para que os indivÃduos possam exercer atividades agrÃcolas em regiÃes como esta, embora seja a atividade que mais desperdice Ãgua. à necessÃrio que se utilizem mÃtodos de irrigaÃÃo que permitam o maior aproveitamento desse precioso lÃquido. Com o objetivo de possibilitar ao agricultor meios para produzir, de promover a melhoria de vida do produtor rural e de gerar desenvolvimento local e regional, surgem os programas de irrigaÃÃo implantados pelo Governo atravÃs do Departamento Nacional de Obras Contra as Secas (DNOCS), como o projeto do PerÃmetro Irrigado Baixo AcaraÃ. No entanto, o desempenho destes projetos precisa ser avaliado, jà que se constituem num custo de oportunidade muito grande para a sociedade. Desta forma, conduziu-se este trabalho, com o objetivo de analisar a (auto) sustentabilidade do PerÃmetro Irrigado Baixo AcaraÃ, avaliando questÃes econÃmico-financeiras, as dimensÃes social, ambiental, econÃmica e institucional, por meio de um conjunto de Ãndices de sustentabilidade capazes de possibilitar o entendimento da realidade da regiÃo, alÃm de observar as caracterÃsticas dos irrigantes deste perÃmetro e sua integraÃÃo rumo ao desenvolvimento sustentÃvel. O procedimento metodolÃgico adotado iniciou-se com a coleta dos dados primÃrios, que foram tratados e organizados. A seguir, foram construÃdos o Ãndice de sustentabilidade e os Ãndices individuais de sustentabilidade para as dimensÃes social, ambiental, econÃmica e institucional. Os Ãndices resultantes deste estudo sÃo apresentados e os resultados indicam que a sustentabilidade no PerÃmetro Irrigado Baixo Acaraà pode ser questionada, uma vez que o Ãndice de sustentabilidade apresenta grau mÃdio e os Ãndices individuais para as dimensÃes apresentam Ãndices de sustentabilidade de grau mÃdio ou ruim, o que sinaliza que esta atividade ainda nÃo se traduziu em melhores condiÃÃes vida e desenvolvimento para a populaÃÃo local. / All across the national territory a preoccupation with the insufficiency of the hydric resources can be noticed, such resources become scarcer as the population, industry and agriculture grows. This issue is even more complicated in the Brazilian semi arid, because there is the interference of the climate factors, such as droughts and irregular rain distribution that compromise the water availability. The use of irrigation becomes essential for the individuals to perform agricultural activities in such regions, although those activities are the ones that waste water the most. Irrigation methods that allow the greatest use of this precious liquid should be adopted. With the objective of giving the cropper ways to produce and a life improvement and to generate both local and regional development, arise irrigation programs implanted by the Government through the National Department of Works Against the Drought (DNOCS), such as the Baixo Acaraà Irrigation Perimeter project. However, the execution of those projects need to be evaluated they are a large opportunity cost for society. This current research will analyse the (auto) sustainability of the Baixo Acaraà Irrigation Perimeter, evaluating economical and financial matters, social, environmental, economical and institutional dimensions through a group of sustainability indexes capable of providing an understanding of the reality of the region, in addition to observing the characteristics of this perimeterâs irrigators and their integration towards sustainable development. The methodological procedure adopted started with the gathering of the primary data, which were treated and organized. Hereinafter, were built the levels of sustainability and the individual sustainability indexes for the social, environmental, economical and institutional dimensions. The resulting indexes from this studies are presented and the results indicate that the sustainability in the Baixo Acaraà Irrigation Perimeter can be questioned, once the sustainability index shows a medium or poor degree, which indicates that this activities has not translated itself into better life conditions and development to the local population yet.

AnÃlise da Capacidade de pagamento versus a disposiÃÃo a pagar pelo uso da Ãgua dos irrigantes do PerÃmetro Irrigado Baixo AcaraÃ: um estudo de caso / Analysis of capacity to pay versus willingness to pay for water use of irrigants in the irrigated Baixo AcaraÃ: a case study

Juliana Viana Jales 30 June 2009 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / FundaÃÃo de Amparo à Pesquisa do Estado do Cearà / O objetivo geral deste trabalho foi analisar o grau de sustentabilidade do PerÃmetro Irrigado Baixo AcaraÃ, de acordo com a capacidade de pagamento e a disposiÃÃo a pagar dos seus irrigantes. Foram utilizados dados secundÃrios e dados primÃrios, atravÃs da aplicaÃÃo de questionÃrios e realizaÃÃo de oficina. A metodologia empregada para anÃlise da capacidade de pagamento foi o levantamento das caracterÃsticas socioeconÃmicas dos irrigantes e o modelo conceitual bÃsico denominado de âmÃtodo residualâ. Para anÃlise da alocaÃÃo eficiente dos fatores de produÃÃo, utilizou-se a funÃÃo de produÃÃo do tipo Cobb-Douglas. Para anÃlise da disposiÃÃo a pagar, aplicaram-se questionÃrios. Em relaÃÃo à capacidade de pagamento, 21 irrigantes (61,76%) mostraram-se sem capacidade de pagamento e trÃs (8,82%) nÃo apresentaram disposiÃÃo a pagar. A funÃÃo de produÃÃo apresentou um coeficiente de determinaÃÃo de 71%, mostrando que 71% da variaÃÃo na produÃÃo podem ser explicados pelas variÃveis incluÃdas no modelo. Apesar das hipÃteses do modelo clÃssico terem sido testadas e todas terem sido atendidas, a estatÃstica t dos coeficientes estimados nÃo mostrou significÃncia, exceto para os insumos. Jà a funÃÃo polinomial, tendo a Ãgua como Ãnico fator variÃvel, indicou que a maioria dos produtores està usando Ãgua para produzir de forma racional. Os irrigantes indicaram pontos positivos do PerÃmetro Irrigado, com destaque para a oportunidade de terem um negÃcio prÃprio e a busca por uma melhor qualidade de vida, enquanto entre os pontos negativos do PerÃmetro, os mais apontados foram o acesso a serviÃos bÃsicos, a falta de organizaÃÃo dos produtores e a falta de assistÃncia tÃcnica. Conclui-se que os irrigantes do PerÃmetro Irrigado Baixo AcaraÃ, em geral, nÃo apresentaram, capacidade de pagamento no perÃodo estudado, enquanto, individualmente, a maior parte nÃo apresentou capacidade de pagamento. Apesar da qualidade da infraestrutra do PerÃmetro e de os irrigantes terem disposiÃÃo a pagar pela Ãgua que utilizam, ainda nÃo tÃm capacidade de pagamento pelo uso da Ãgua, dado que estÃo desorganizados e nÃo alcanÃam bons nÃveis de produÃÃo e de comercializaÃÃo. Por consequÃncia, o PerÃmetro nÃo mostra um nÃvel de sustentabilidade aceitÃvel. A desorganizaÃÃo dos irrigantes nÃo permite estabelecer estratÃgias que levem a um melhor desempenho dos irrigantes do PerÃmetro Irrigado Baixo Acaraà / The objective of this study was to analyze the degree of sustainability of the Irrigated Perimeter Baixo Acaraà according to capacity to pay and willingness to pay of it irrigants. It was used secondary data and primary data from public institutions and the application of questionnaires and conduct of participative research. The methodology used for analysis of capacity to pay was through the removal of the socioeconomic characteristics of irrigant and the basic conceptual model called the "residual method". For analysis of the efficient allocation of production factors built up to the production function of Cobb-Douglas type. For analysis of the willingness to pay, questionnaires were applied. In relation to ability to pay, 21 irrigant (61.76%) proved to be without capacity to pay and three (8.82%) showed no willingness to pay. The production function showed a determination coefficient of 71%, showing that 71% of the variation in production can be explained by the variables included in the model. Despite the assumptions of the classical model have been tested and all have been met, the t statistic of the estimated coefficients were not significant, except for the inputs. The polynomial function having water as the only variable factor indicated that the majority of producers are using water to produce a rational way. The irrigant showed positive points of the Irrigated Perimeter, with emphasis on the opportunity to have their own business and search for a better quality of life, while among the negative points of the perimeter, the most mentioned were access to basic services, lack of organization producers and the lack of technical assistance. It is concluded that irrigants of the Irrigated Perimeter Baixo Acaraà do not generally presented, capacity to pay during the period studied, while individually, most showed no capacity to pay. Despite the of perimeter infrastructure quality and the fact of irrigants to have willingness to pay for water they use, they donât have capacity to pay for water use, as they are disorganized and do not reach good levels of production and marketing. Consequently, the perimeter does not show an acceptable level of sustainability. The disorganization of irrigants does not permit to establish strategies that lead to better performance of irrigants in the Irrigated Perimeter Baixo AcaraÃ

O exame andrológico é uma importante ferramenta para a identificação de reprodutores sub férteis e para o monitoramento da qualidade seminal. Porém, poucas características do exame estão correlacionadas com a fertilidade in vivo. Assim, é fundamental a identificação de métodos que possam auxiliar na seleção mais precisa dos futuros reprodutores. Os objetivos do primeiro trabalho foram avaliar as acurácias e o viés das predições genômicas, utilizando diferentes métodos, para a característica perímetro escrotal ajustado à idade e ajustado à idade e peso em touros das raças Hereford e Braford. Os valores estimados para a herdabilidade apresentaram magnitude moderada a alta (0,39 a 0,48), demonstrando que é possível a obtenção de ganhos genéticos a partir da seleção. A predição de valores genéticos utilizando informações genômicas pelos métodos índice de seleção e single-step possibilitou o aumento de acurácia (em torno de 30%) para as características estudadas. Os ganhos de acurácia obtidos com os métodos, combinando as informações tradicionais com a genômica em relação ao método BLUP tradicional indicam que as predições genômicas podem ser usadas como ferramenta para melhorar os ganhos genéticos e reduzir o intervalo de gerações. Já o segundo artigo teve como objetivos: determinar a expressão de RNAm das paraoxonases (PON) 1, 2 e 3 no parênquima testicular, vesículas seminais e epidídimo de touros, avaliar a atividade de PON1 na circulação sanguínea e no plasma seminal; e correlacionar esta atividade com características avaliadas durante o exame andrológico. A caracterização da expressão dos genes foi realizada por qRT-PCR e a determinação da atividade de PON1 foi realizada em amostras de soro e plasma seminal provenientes de 110 touros. As PON 1, 2 e 3 foram expressas no parênquima testicular dos animais analisados. Observou-se uma correlação positiva entre a atividade sérica e seminal de PON1 com diversos indicadores de fertilidade. / Male fertility is important to optimize pregnancy rates and genetic improvement. Breeding soundness evaluations are key tools to identify sub fertile males and to survey characteristics of sperm quality. However, few sperm quality traits are correlated with fertility in vivo. Thus, it is essential to identify methods that can assist in more precise selection of future bulls. The goals of the first study were to evaluate the accuracy and the bias of the genomic predictions, using different methods, for the characteristic scrotal perimeter adjusted to age and adjusted to age and weight in Hereford and Braford bulls. The estimates for the heritability showed moderate to high magnitude (0.39 to 0.48), demonstrating that it is possible to obtain genetic gains from selection. The prediction of genetic values using genomic information by methods of selection index and single-step made possible the increase of accuracy (around 30%) for the characteristics studied. The gains in accuracy obtained with the methods, combining the traditional with the genomic information compared to traditional BLUP method indicate that the genomic predictions can be used as a tool to improve the genetic gains and reduce the range of generations. The second article had as its objectives: to determine the mRNA expression of paraoxonases (PON) 1, 2 and 3 in the testicular parenchyma, seminal vesicles, and epididymis of bulls, to evaluate the activity of PON1 in the bloodstream and in seminal plasma; and to correlate that activity with characteristics of breeding soundness. Characterization of gene expression by qRT-PCR and the determination of PON1 activity were performed in serum and seminal plasma from bulls 110. The PON 1, 2 and 3 were expressed in testicular parenchyma of the animals examined. There was a positive correlation between activity and serum PON1 seminal with different breeding soundness estimators.
