1. Numerical solution of the Falkner-Skan equation using third-order and high-order-compact finite difference schemes
We present a computational study of the solution of the Falkner-Skan equation (a thirdorder boundary value problem arising in boundary-layer theory) using high-order and high-order-compact finite differences schemes. There are a number of previously reported solution approaches that adopt a reduced-order system of equations, and numerical methods such as: sh

2. DFLD-EXP: uma solução semi-analítica para a equação de advecção-dispersão / DFLD-EXP: a semi-analytic solution for the advection-dispersion equation
A equação de advecção-dispersão possui grande importância na engenharia e nas ciências aplicadas. No entanto, como é bem conhecido, a obtenção de uma solução numérica apropriada para essa equação é um problema desafiador tanto para engenheiros como para matemáticos, físicos e outros profissionais que trabalham com a modelagem de fenômenos

3. MÉTODOS APROXIMADOS DE SOLUÇÃO DE SISTEMAS DINÂMICOS NÃO-LINEARES / APPROXIMATE SOLUTION METHODS FOR NONLINEAR DYNAMICAL SYSTEMS
Nonlinear dynamical systems are rather common in engineering. This class of problems is usually solved by numerical integration or through the use of ap- proximate analytical methods (perturbation methods) or semi-analytical meth- ods such as the harmonic balance method. The numerical integration is a slow and cumbersome process in parametric analyses. The o

4. Effects of solar neutrinos scale on atmospheric neutrino flux
In this work we try to understand the phenomena of neutrino oscillations, and use this to obtain a more precise description of the atmospheric neutrino data. The two neutrino oscillation mechanism solves the problem of the up-down muon neutrino asymmetry successfully. Our main motivation is to describe the excess of events of electron-neutrino type found in

5. ExtensÃo de uma soluÃÃo K-Jato de uma estrutura tubular
In the present work we introduce the notions of a k−Jet Solution and of a (Â, k)−Convex Envelope to prove a semi-local Bochnerâs Tube Extension Theorem for the category of real analytic tubular structures giving a integral representation for the extension

6. "O acolhimento num centro de atenção psicossocial" / The welcoming at a Psychosocial Care Center.
Welcoming arises as a reorganizer of health services with a view to universal access, improvement in care quality, favoring the relation between user/health worker and widening intervention. The study object of this research is the welcoming of users at the Psychosocial Care Center Castelo Simões Lopes in Pelotas, Rio Grande do Sul, Brazil. We aimed to anal
