1. A Intermodalidade no Transporte de Etanol Brasileiro: aplicação de um modelo de equilíbrio parcial
Resumo: A busca por fontes de energia renováveis tem aumentado a demanda mundial de etanol. O Brasil é o segundo maior produtor; porém, os custos para transportar a produção são cada vez mais altos. O objetivo do presente artigo é analisar as alternativas de transporte para o etanol frente às condições da logística vigentes no Brasil. Para tanto,

2. Analysis of Spinodal Decomposition in Al-Zn and Al-Zn-Cu Alloys Using the Nonlinear Cahn-Hilliard Equation
The phase field model based on the nonlinear Cahn-Hilliard equation was applied to analyze the spinodal decomposition process in Al-Zn and Al-Zn-Cu alloys. Partial differential equations were solved using the explicit finite difference method for the Al- 20, and 35 at. % Zn alloys aged at temperatures between 25 and 100 °C for times from 10 s to 2000 s and

3. AN EOS-BASED NUMERICAL SIMULATION OF THERMAL RECOVERY PROCESS USING UNSTRUCTURED MESHES
Abstract In the past thirty years, the development of compositional reservoir simulators using an equation of state (EOS) has been addressed in the literature. However, the development of compositional thermal simulators in conjunction with the EOS formulation, in particular, has not been addressed extensively. In this work, a fully implicit, thermal, compos

4. General exact harmonic analysis of in-plane timoshenko beam structures
The exact solution for the problem of damped, steady state response, of in-plane Timoshenko frames subjected to harmonically time varying external forces is here described. The solution is obtained by using the classical dynamic stiffness matrix (DSM), which is non-linear and transcendental in respect to the excitation frequency, and by performing the harmon

5. The meat market: a dea international perspective and an econometric behavioral model for Brazil
We describe the relative participation of the Brazilian meat market (beef, pork and chicken) in total agribusiness exports and in total country exports. An analysis of the world meat market is carried out from the point of view of the values of consumption, production, exports and imports. A DEA (data envelopment analysis) approach is then used to generate c

6. Essays in heterogeneous agent macroeconomics
This thesis is comprised of three chapters. The first article studies the determinants of the labor force participation of elderly American males and investigates the factors that may account for the changes in retirement between 1950 and 2000. We develop a life-cycle general equilibrium model with endogenous retirement that embeds Social Security legislatio

7. A tutorial on hypercube queueing models and some practical applications in Emergency Service Systems
This paper presents some extensions and applications of hypercube queueing models todescribe server-to-customer type Emergency Service Systems. The classical hypercube is a well-known spatially distributed queueing model effective in analyzing these systems, based on Markovian analysis approximations. Experience has shown that each real life Emergency Servic

8. The meat market in Brazil: a partial equilibrium model.
Um modelo de equilíbrio parcial para o mercado brasileiro de carnes é ajustado por meio de mínimos quadrados em três estágios. O modelo mostra-se consistente com as observações e pode ser usado para simulações. Neste contexto, comparam-se simulações para o futuro próximo com as projeções da OECD/Aglink. Para ilustrar o emprego do modelo em simu

10. The U.S. Generalized System of Preferences: an estimate of the impacts on the Brazilian exports / O Sistema Geral de Preferência dos EUA:uma estimativa dos impostos sobre as exportações brasileiras
The Generalized System of Preferences (GSP), main example of the preferential tariff concessions offered unilaterally by developed countries, has been used by developing countries for more than 30 years. The U.S. GSP, one of the most important programs to Brazil, has been causing some apprehension due to threats made by the U.S. to exclude this country from

11. Mating and offspring frequencies under partial outcrossing in a structured population
This paper gives a model of a structured population with respect to an autosomal locus with two alleles. The population reproduces in discrete and non-overlapping generations. The population is assumed to be in equilibrium in that exactly the same distribution of genotypic proportions is reproduced in each generation. The population is subdivided into 'local

12. CRIAÇÃO E DESVIO DE COMÉRCIO NO MERCOSUL: O CASO DO ARROZ EM CASCA / TRADE CREATION AND DIVERSION IN MERCOSUL: THE CASE OF THE ROUGH RICE
The Regional Integration Agreements surround the international economy as an alternative to total liberalization of markets. Latin America was not astonished with the resurgence of the post-cold war regionalism. Regarding the imperfect customs union Mercosur, even when in this kind of agreement the goal is a Common External Tariff (CET) that would stimulate
