1. Aplicação de solução semianalítica para modelagem de ensaios de sorção e difusão pura com lixiviado
RESUMO A implementação da Política Nacional de Resíduos Sólidos (Lei nº 12.305, de 2 de agosto de 2010) foi um marco para a disposição final e o tratamento de resíduos sólidos no país. A contaminação decorrente da negligência na disposição dos resíduos sólidos urbanos atinge sistemas naturais vitais para a existência humana. Torna-se, port

2. CONDITIONAL PRICING MODEL WITH HETEROSCEDASTICITY: EVALUATION OF BRAZILIAN FUNDS
RESUMO Os resultados empíricos na literatura demonstram que a versão condicional do Modelo de Precificação de Ativos Financeiros (CAPM), particularmente no que se refere ao modelo na forma em espaço de estado, no qual o beta é estimado pelo filtro de Kalman, possui maior poder explicativo do que a sua versão incondicional. A maioria das análises emp�

3. Study of Gas Turbulent Dispersion Process in the Alcântara Launch Center
ABSTRACT: The Alcântara Launch Center (ALC) is the Brazilian gate to the space located at the north coast of Maranhão State, close to the Equator. Topographical local characteristics modify the parameters of incident atmospheric winds and it can cause great influence on the gas dispersion process. In this work, detailed scale models of the ALC region was e

4. Prediction of Topsoil Texture Through Regression Trees and Multiple Linear Regressions
ABSTRACT: Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear R

5. Predictors of success for mandibular repositioning appliance in obstructive sleep apnea syndrome
Abstract The characteristics of non-obese patients with mild to moderate Obstructive Sleep Apnea Syndrome (OSAS) who will present with a good response to Mandibular Repositioning Appliance (MRA) treatment have not yet been well established in the literature. The aim of this study is to assess whether polysomnographic (PSG), demographic, anthropometric, cepha

6. Verificação da previsão do tempo em São Paulo com o modelo operacional WRF / Review of weather in São Paulo with the WRF Operational Model.
Forecasts of daily maximum and minimum temperatures and rainfall performed by the operational numerical weather prediction WRF (Weather Research Forecasting) model in the São Paulo are evaluated. Initial and boundary conditions provided by the 00UTC Global Forecast System (GFS) Model and WRF run for 72 hours, with two nested grids (with horizontal grid spac

7. Modelagem estatística de extremos espaciais com base em processos max-stable aplicados a dados meteorológicos no estado do Paraná / Statistical modelling of spatial extremes based on max-stable processes applied to environmental data in the Parana State
The most mathematical models developed for rare events are based on probabilistic models for extremes. Although the tools for statistical modeling of univariate and multivariate extremes are well-developed, the extension of these tools to model spatial extremes data is currently a very active area of research. Modeling of maximum values under the spatial dom

8. The Forward- and the Equity-Premium Puzzles: Two Symptoms of the Same Illness?
Using information on US domestic financial data only, we build a stochastic discount factor—SDF— and check whether it accounts for foreign markets stylized facts that escape consumption based models. By interpreting our SDF as the projection of a pricing kernel from a fully specified model in the space of returns, our results indicate that a model that a

9. Revalorização Urbana no Centro Histórico de São Paulo : uma análise dos novos usos / Redeveloping the Urban Historic Centre of São Paulo : an analysis of new uses
The purpose of this study was to understand how the ideological and practical design of the revaluation of the urban center of Sao Paulo has been developed and materialized in space, thanks to the actions of the government in partnership with the private sector. And as an idealized scenario and desired by local elites permeates and pervades the urban plannin

11. A produção dos espaços dos cerrados baianos após 1970.
This paper presents a study about the capitalist production of a space. It focuses on how the region of savannas in Bahia was planned and produced to be part of a new capitalist dynamic. The study analyzes since the end of the 1970s until now, once that the consolidation of modern agriculture in the space took place exactly in this period. This new process h

12. Geometria e simetrias do emaranhamento
In the present work we present a geometric method to identify and measure the degree of entanglement of a two-qubit state. It is based on writing a map of the system state, from a non-unitary transformation. By introducing new parameters for such 4X4 matrix, the product of eigenvalues, two by two, acquire the form of squared 4D distances, having a Minkowski
