1. O equilíbrio e a estrutura estelar em uma abordagem simples: a Seqüência Principal
Resumo As condições simultâneas de equilíbrio Virial e equilíbrio hidrostático determinam a existência de soluções para os modelos estelares mais simples. Utilizando estes dois conceitos mostramos que é possível caracterizar a estrutura estelar sem recorrer à integração de equações diferenciais, ao menos para obter as propriedades globais. Al

2. Simultaneous Equations to Estimate Aboveground Biomass of Pinus caribaea var . hondurensis
ABSTRACT This study aimed to develop equations to predict the biomass of trunks, branches, needles and total individual biomass for Pinus caribaea var. hondurensis . A simultaneous equation system was also adjusted. Twenty (20) trees from the experimental area of the State University of Southwest Bahia (UESB), Vitória da Conquista, Bahia, Brazil, were meas

3. Simultaneous prestack seismic inversion in a carbonate reservoir
Abstract We applied a method of Simultaneous Prestack Seismic Inversion (SPSI) in a hydrocarbon field located in the Campos Basin, Brazil. The goal was to study the application of this method to Albian carbonate rocks of the Quissamã Formation. Based on what is found in nearby fields, this Formation potentially contains hydrocarbon accumulations that can be

4. Equações simultâneas no contexto clássico e bayesiano : uma abordagem à produção de soja.
Nos últimos anos tem aumentado a quantidade de pesquisadores e pesquisas científicas na plantação, produção e valor de soja no Brasil, em grão. Diante disso, a presente dissertação busca analisar os dados e ajustar modelos que expliquem, de forma satisfatória, a variabilidade observada da quantidade produzida e valor da produção de soja em grão

5. Determinantes da Composição do Endividamento das Empresas Brasileiras: a consideração da maturidade e da fonte de financiamento
In corporate finance field, there is a vast literature about the capital structure determinants. However, studies have focused on the differences between equity and debt, while the literature about debt structure (maturity and source) is relatively scarce. As such, this study aims to promote empirical research about characteristics that influence debt maturi

6. BenefÃcios Sociais da PolÃtica de Incentivo à Cultura do MamÃo no Estado do Cearà / Social benefits of Incentive Policy related to Papaya crop in the State of CearÃ
The objective of this study is to analyze it benefit social generated by the Government s incentives of Cearà to the producing of papaya of the State, in the period from 2001 to 2006, considering as theoretical base the models of simultaneous equations and of approach of Marshall s economical surplus. For so much, a series of annual data was used, considere

7. As interações entre o setor saúde e a saúde mental a partir das estatísticas de ciência e tecnologia
The aim of this thesis is to place the mental health theme within the discussion about the innovation health system. Firstly, the health sector was compared to the other sectors of economic activity from a theoretical point of view. As the differences among them proved to be substantial, studies on the health sector started to be carried out. The focus of th

8. Produção de petroleo por elevação a gas intermitente : simulação e analise dos metodos convencional e invertido / Petroleum production by intermittent gas lift: simulation and analysis of conventional and inverted methods
The intermittent gas lift is used in the oil industry to keep up a viable production from depleting reservoirs or low productivity wells. The cyclical pattern of the intermittent gas lift causes the dynamic behavior of the well to become complex, making it difficult to design and operate of such systems. Amongst the existing versions, the conventional (IGL)

9. {Kinetic simulations to modeling events in space plasmas} / Simulação cinéticas para modelagens de fenômenos em plasma espaciais
- The purpose of this doctoral thesis is to study some phenomena in space plasma using theoretical models and computer simulation via particles. Firstly, we concentrate on studying the process involving nonlinear interactions among Langmuir, electromagnetic and ion acoustic waves, associated with type III solar radio bursts. Starting from the generalized Zak

10. REAL EXCHANGE RATE AND COMMODITY PRICES: RELATION IDENTIFIED USING CHANGES OF EXCHANGE RATE REGIME / CÂMBIO REAL E PREÇOS DE COMMODITIES: RELAÇÃO IDENTIFICADA ATRAVÉS DE MUDANÇA DE REGIME CAMBIAL
Using Rigobons (2001) identification method for simultaneous equations models, based on the heteroskedasticity of the structural shocks, we analyze the relationship between the exchange rate and commodity prices for specific countries. Instead of the traditional approach of the commodity currency literature, we allow for endogenous effects of the exchange ra

11. People management by the development of organizational commitment: a holistic and simultaneous approach of the determinants involved in the process / Gestão de pessoas pelo desenvolvimento do comprometimento organizacional: uma abordagem holística e simultânea dos determinantes envolvidos no processo
The importance of the collaborator´s commitment to the organization´s objectives is evidenced in function of the new paradigm of industrial production: the integrated flexible automation. Since the beginning of mass production plants started by the automobile industry until recently, the paradigm taylorism/fordism has been the dominant. This model, marked

12. Estrategias numericas para solução de modelos de não-equilibrio para absorção gasosa com reações quimicas complexas (regime estacionario e dinamico)
Gas absorption with chemical reactions is a very common industrial separation processo Until now the traditional equilibrium stage model have been the main tools to the design and unsteady state simulations of the gas-liquid contact equipment. The nonequilibrium model based on mass transfers fundamentais presents a more realistic description of the gas-liqui
