1. ASSOCIAÇÃO ENTRE MÉTODOS DE ADAPTABILIDADE E DE ESTABILIDADE EM FEIJÃO / ASSOCIATION BETWEEN ADAPTABILITY AND ESTABILITY METHODS IN COMMON BEAN
The study of adaptability and yield stability allows to identify cultivars adapted to specific conditions and wide, stable and with high grain yield, and can be realized as the different methodologies employed. Thus, the aim of this study was to investigate the association between adaptability and stability methods for grain yield in common bean cultivars an

2. Uma condição de injetividade e a estabilidade assintótica global no plano / A injectividade condition and the global asymptotic estability on the plane
Neste trabalho, estamos interessados em estudar a solução do seguinte problema: Seja Y = ( f ,g) um campo de vetores, de classe C1, em R2. Suponha que (x, y) = (0,0) é um ponto singular de Y e suponha que, para todo q ∈ R2, os autovalores de DY tem parte real negativa, isto é, det(DY) >0 e tr(DY) <0. Então, a solução (x, y) = (0,0) de Y é globa

3. Uma condição de injetividade e a estabilidade assintótica global no plano / A injectividade condition and the global asymptotic estability on the plane
In this work we are interested in the solution of the following problem: Let Y = ( f ,g) be a vector field of class C1 in R2. Suppose that (x, y) = (0,0) is a singular point of Y and assume that for any q ∈ R2, the eigenvalues of DY have negative real part, this is, det(DY) >0 and tr(DY) <0. Then, the solution (x, y) = (0,0) of Y is globally asymptotic

4. Existencia e estabilidade de ondas viajantes periodicas para alguns modelos dispersivos / Existence and stability of periodic travelling waves for some dispersive models
The goal of this thesis is to study the properties of solutions of some dispersive differential equations. First, we develop a local and global well-posedness theory for the regularized Benjamin-Ono equation in the periodic setting, then, we show that the Cauchy problem for this equation (in both periodic and nonperiodic cases) cannot be solved by an iterati

5. Estudo proteômico do efeito da atmosfera modificada na estabilidade da cor e na vida útil da carne suína acondicionada em embalagens de transporte tipo masterpack sob refrigeração / Proteomics study of the effect of modified atmosphere on colour estability and shelf life of pork meat wrapped in masterpack transport packages under refrigeration
The aim of this work was to study the effect of modified atmosphere associated to "masterpack" transport packages in the shelf-life of refrigerated pork meat. Microbiological, physical-chemical, biochemical and visual analyses were made. Pork loin (Longissimus dorsi) cuts placed in trays of expanded polystyrene, covered with poly(vinyl chloride) films were u

6. AvaliaÃÃo genotÃpica de linhagens de arroz de terras altas via metodologia de modelos mistos / Evaluation genotypic of the lines dryland rice using mixed models methodology
Em programas de melhoramento genÃtico de plantas, linhagens sÃo constantemente avaliadas em diversos ambientes, com o propÃsito de verificar o comportamento diferencial em resposta Ãs diversas variaÃÃes ambientais. Para tanto, a seleÃÃo deve ser baseada em modelos estatÃsticos e biomÃtricos, o mais acurados possÃvel, para que os programas sejam ef

7. The tax administration like essential activities for State working / A administração tributária como atividade essencial ao funcionamento do Estado
This present paper intends to show that the tax administration activities on three level of government (federal, state and municipal) are essential activities for State working, under the terms of the specific constitutional prevision (FC/88, art. 37, XXII, c/c and CA 42/2003). According to this constitutional device for the tax administration are raised on

8. A produção do paradoxo entre homem e real: ressentimento e rebeldia em Feliz Ano Novo / The paradox between man and reality: ressentment and rebellion in Feliz Ano Novo
This present dissertation had intended, in the first moment, to discuss the marking lines of the knowledges with which literature dialogues constantly, specially with philosophy. In the attempt of making visible the permeability of these knowledges, confronting borders and breaking the epistemological limits, we have analysed the book of short-histories Feli

9. AVALIAÇÃO CEFALOMÉTRICA DA ESTABILIDADE DO TRATAMENTO COM O REGULADOR DE FUNÇÃO FRÄNKEL-2 / Cephalometric estability evaluation of the treatment with Fränkel-2 Functional Regulator appliance
The aim of this study consisted of comparing dental, skeletal and soft tissue effects promoted by Frankel-2 functional regulator with a control group, besides observing the stability of those effects, in an average post-treatment period of 7.11 years. The sample had a total of 90 lateral cephalometric radiographs, with 54 cephalometric radiographs of 18 FR-2

11. Caracterização vibracional e térmica de blendas de LDPE e m-LLDPE / Thermal and vibrational characterization of blends: Blends of low density polyethylene (LDPE) and linear low density polyethylene synthesized with the metallocene catalyst (m-LLDPE)
Blends of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) are used commercially to improve the final properties of the products and their process, reduce the production cost having as their main segment packing film. The LLDPE used in this work was synthesized with the metallocene catalyst (m-LLDPE), which was projected to offer b

12. Sistemas de cultivo integrados baseados no conceito de emissão zero em micro-escala
A great predatory pressure on the reduced number of fishing option has produced difficulty to the market to cover the demand of fishing products. This fact justifies itself by the domain of the linear products that envolve the unilateral technologies of the exploitation of the resources, this limits the possibility of choice of the product. The final objecti
