1. Validation of the Portuguese version of the Community Assessment of Psychic Experiences and characterization of psychotic experiences in a Brazilian sample
Objective: We investigated: i) the reliability and validity of a Brazilian version of the Community Assessment of Psychic Experiences (CAPE), developed to detect and characterize psychotic experiences in the general population; and ii) the association between psychotic experiences, childhood adversity, and cannabis use in a population-based sample. Methods

2. Numerical implementation of a micromechanics-based viscoelastic model for geomaterials with isotropically distributed micro-fractures
Abstract The constitutive behavior of geomaterials is generally affected by the presence at different scales of discontinuity surfaces with different sizes and orientations. According to their mechanical behavior, such discontinuities can be distinguished as cracks or fractures. Fractures are interfaces that can transfer normal and tangential stresses, where

3. A Model for Homogenization of Linear Viscoelastic Periodic Composite Materials with Imperfect Interface
Abstract In this paper, a micromechanical extension of the finite-volume direct averaging micromechanics theory (FVDAM) is presented for evaluation of the homogenized relaxation moduli of linear viscoelastic unidirectional fiber reinforced composites with periodic microstructures. Such materials are assumed as composed of repeating unit cell with arbitrary i

4. The Splitting Method and the GFEMin the Two-Dimensional Analysis of Linear Elastic Domains with Multiple Cracks
Abstract The aim of this paper is to analyse two-dimensional linear elastic continuum containing multiple interacting cracks. Both the mechanical model and the numerical approach are addressed throughout the text as key concepts for the computational framework, whose main characteristics will be described. The Splitting Method is a decomposition method consi

5. Relationship between viral load and behavioral measures of adherence to antiretroviral therapy in children living with human immunodeficiency virus in Latin America
Few studies have examined antiretroviral therapy adherence in Latin American children. Standardized behavioral measures were applied to a large cohort of human immunodeficiency virus-infected children in Brazil, Mexico, and Peru to assess adherence to prescribed antiretroviral therapy doses during the three days prior to study visits, assess timing of last m

6. Integral transform solution of natural convection in a square cavity with volumetric heat generation
The generalized integral transform technique (GITT) is employed to obtain a hybrid numerical-analytical solution of natural convection in a cavity with volumetric heat generation. The hybrid nature of this approach allows for the establishment of benchmark results in the solution of non-linear partial differential equation systems, including the coupled set

7. Estimação de parâmetros genéticos para características de crescimento, reprodução e categóricas em uma população de bovinos de corte compostos (Bos taurus x Box indicus) sob abordagem bayesiana e modelos lineares generalizados mistos / Estimation of genetic parameters for traits of growth, reproduction and categorical in a population of composite beef cattle (Bos taurus x Bos indicus) in Bayesian approach and generalized linear mixed models
Os objetivos deste trabalho foram avaliar diferentes modelos de seleção com base nos efeitos aleatórios maternos considerados para características de crescimento e perímetro escrotal, estimar parâmetros genéticos para pesos do nascimento aos 12 meses (pesos ao nascer, a desmama e aos 12 meses de idade); perímetro escrotal aos 12 meses e correlações

8. Numerical solution of the variational PDEs arising in optimal control theory
An iterative method based on Picard's approach to ODEs' initial-value problems is proposed to solve first-order quasilinear PDEs with matrix-valued unknowns, in particular, the recently discovered variational PDEs for the missing boundary values in Hamilton equations of optimal control. As illustrations the iterative numerical solutions are checked against t

9. Estabilidade e estabilização de uma classe de sistemas não-lineares sujeitos a saturação
This work addresses the problem of stability analysis and stabilization of nonlinear rational systems subject to saturation. The approach used in this study is based on the differential algebraic representation (DAR) of rational systems and on a modified version of the generalized sector condition to deal with saturation. First, methods to characterize the s

10. Análise da distribuição espaço-temporal da leishmaniose visceral e perfil clínico-epidemiológico dos casos e óbitos, Belo Horizonte Minas Gerais, 1994 a 2009
Since the decade of 1980, the visceral leishmaniasis (VL) has expanded to major urban centers of Brazil. Several factors contribute to this situation and among them the great mobility of populations, environmental changes and the increase in population density, which promote contact between humans, vectors and other animals. In this latter group the dog is t

11. GENERALIZED LINEAR APPROACH TO ESTIMATE NON-TECHNICAL LOSSES OF ELECTRICAL ENERGY / ABORDAGEM LINEAR GENERALIZADA PARA ESTIMAR PERDAS NÃO TÉCNICAS DE ENERGIA ELÉTRICA
A necessidade de simular um ambiente de mercado competitivo para incentivar ganhos de eficiência fez a Agência Nacional de Energia Elétrica (ANEEL) estipular metas para indicadores gerenciáveis, dentre eles o nível de perdas não técnicas (PNT¿s) das distribuidoras de energia elétrica. Os prejuízos causados pelas perdas não técnicas de energia che

12. Sobre o acoplamento fluido-casca utilizando o método dos elementos finitos / On fluid-shell coupling using the finite element method
This work consists of the development of computational tools for nonlinear geometric fluid-shell interaction analysis using the Finite Element Method (FEM). The fluid solver is explicit and its time integration based on characteristics. The computational code is able to simulate the Navier-Stokes equations for compressible flows written in the Eulerian descr
