1. Development of Sliding Connections for Structural Analysis by a Total Lagrangian FEM Formulation
Abstract In this study a total lagrangian 2D finite element formulation is used to model plane frames developing large displacements and rotations considering sliding connections. This kind of connections is usually called prismatic and cylindrical joints. In order to be self-containing, the steps of the development of a frame finite element of any approxima

2. Optimum dynamic analysis of 2D frames using free-scaled wavelet functions
This paper presents a wavelet-based scheme for dynamic analysis of 2-dimensional (2D) frames. In the proposed approach, free-scaled wavelet functions are developed for Multi-Degrees-of-Freedom (MDOF) structures, particularly, complex Chebyshev and simple Haar wavelets are implemented. A simple step-by-step and explicit algorithm is presented to calculate the

3. Numerical combination for nonlinear analysis of structures coupled to layered soils
This paper presents an alternative coupling strategy between the Boundary Element Method (BEM) and the Finite Element Method (FEM) in order to create a computational code for the analysis of geometrical nonlinear 2D frames coupled to layered soils. The soil is modeled via BEM, considering multiple inclusions and internal load lines, through an alternative fo

4. Tensor baseado em fluxo óptico para descrição global de movimento em vídeos
Movimento é uma das características fundamentais que refletem a informação semântica em vídeos. Uma das técnicas de estimativa do movimento é o cálculo do fluxo óptico. Este é uma representação 2D (bidimensional) das velocidades aparentes de uma sequência de quadros (frames) adjacentes, ou seja, a projeção 2D do movimento 3D (tridimensional)

5. Protocolo clínico para avaliação de ajustes posturais antecipatórios: desenvolvimento e validação / Clinical protocol for assessment of anticipatory postural adjustments: development and validation
Evaluating motor control is a recurrent practice in physiotherapeutic routine, in which physiotherapist analyzes anticipatory postural adjustments (APAs) and compensatory postural adjustments (CPAs). APAs, subject of interest, precede planned postural perturbation and minimized them through corrections to maintaining the stability. It is known the relationsh

6. EMaD - Uso de um aplicativo multimídia interativo como suporte para ensino da Semiologia Mamária / EMaD - Use of an interactive multimedia application as support for teaching Semiology Breast
The teaching techniques must be dynamic and, in fact, have made constant progress. More recently, and quite aggressive new features that implement information technology have been used in medical education. However, the lack of this feature with respect to its applicability in the teaching of gynecology is significant. The objectives of the current study wer

7. Mutation in the xpsD gene of Xanthomonas axonopodis pv. citri affects cellulose degradation and virulence
The Gram-negative bacterium Xanthomonas axonopodis pv. citri, the causal agent of citrus canker, is a major threat to the citrus industry worldwide. Although this is a leaf spot pathogen, it bears genes highly related to degradation of plant cell walls, which are typically found in plant pathogens that cause symptoms of tissue maceration. Little is known on

8. O jogo de futebol : investigação de sua estrutura, de seus modelos e da inteligencia de jogo, do ponto de vista da complexidade / The soccer game ; : searche of this structure, its models and intelligence of the game from the point of view of complexity
In high-level sports, small things make difference between the first and second positions. The game, and in this is case the soccer game, is a complex phenomenon where the player s performance is transdimensional. At every time players and teams meet problem-situations, in unpredictable circumstances that need fast technical, tactical, physical and psycholog

9. Elastic nonlinear geometric analysis with positional finite element method / Análise de problemas elásticos não lineares geométricos empregando o método dos elementos finitos posicional
Non linear geometric analysis for 2D frames and 3D solids are analyzed in this work by employing the finite element method with positional description. The present formulation does not use the concept of displacement; it considers positions as the real variables of the problem. In addition, the formulation is developed through total lagrangian description. B

10. Análise Não-Linear de Pórticos Tridimensionais Formados por Elementos Mistos de Aço e Concreto
The purpose of this dissertation is the development, implementation and test of numerical models for the Finite Element simulation of plain steel, reinforced concrete and composite steel-concrete three-dimensional frames. Physical (material) and geometrical nonlinearities are taken into account in the Finite Element formulation. At the cross section level, a

11. RelaÃÃo de apego mÃe-crianÃa: um olhar dinÃmico e histÃricorelacional / Mother-child attachement relationship: A dynamic and historical-relational approach
O presente estudo insere-se em um paradigma contemporÃneo de pesquisa que concebe o desenvolvimento humano como um processo de mudanÃa, inserido em um contexto de relaÃÃes interpessoais. Enquanto um sistema dinÃmico, histÃrico e relacional, a pessoa em desenvolvimento està continuamente co-regulando suas aÃÃes em relaÃÃo Ãs aÃÃes das outras pes

The present work was carried out at the National Forest of São Francisco de Paula - FLONA/RS Araucaria Forest, which is of a great species diversity of Rio Grande do Sul. Litter is the material deposited on the soil in the forests and this is very important to the maintenance of soil fertility, because this is how the nutrients return to the plants in the e
