1. Factor structure of the Dimensional Yale-Brown Obsessive-Compulsive Scale in a large sample of adults with obsessive-compulsive disorder
Objectives: Although the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a widely used instrument for assessing different obsessive-compulsive symptom dimensions, its factor structure has never been studied in a Brazilian population. Thus, we aimed to assess the goodness-of-fit indexes and factor loadings of two higher-order models of the DY-B

2. Differentiating irritable mood and disruptive behavior in adults
Abstract Introduction Irritability has both mood and behavioral manifestations. These frequently co-occur, and it is unclear to what extent they are dissociable domains. We used confirmatory factor analysis and external validators to investigate the independence of mood and behavioral components of irritability. Methods The sample comprised 246 patients

3. 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

4. Prediction of quality parameters of food residues using NIR spectroscopy and PLS models based on proximate analysis
Abstract The real-time prediction in biorefinery industries has become essential. Models using partial least square regression (PLS) were developed to predict moisture, ash, volatile matter, fixed carbon and organic matter of coconut and coffee residues. In this study, 49 samples were collected and near infrared spectroscopy were applied to predict moisture,

6. Large deflection and initial instability analysis of anisotropic plates by the generalized finite element method
Abstract This paper presents investigations laminated plates under moderately large transverse displacements and initial instability, through the Generalized Finite Element Methods - GFEM. The von Kármán plate hypothesis are used along with Kirchhoff and Reissner-Mindlin kinematic plate bending models to approximate transverse displacements and critical bu

7. Solar drying of cowpea bean combined with drying in a heat accumulator dryer
RESUMO Como a radiação solar é abundante no Brasil durante quase todo o ano e por ser essa a fonte de energia renovável e não poluente por excelência, a secagem solar dos produtos agrícolas é uma metodologia promissora. Objetivou-se, neste trabalho, secar grãos de feijão-caupi [Vigna unguiculata (L.) Walp.] utilizando energia solar em diferentes te

8. Análise de recalques em longo prazo no vazadouro de Marambaia, Nova Iguaçu, Rio de Janeiro
RESUMO Este artigo versa sobre a análise da compressibilidade dos resíduos sólidos urbanos (RSUs) do antigo vazadouro da Marambaia, localizado no município de Nova Iguaçu, Rio de Janeiro, que operou como um lixão durante o período de 1987 a 2003, quando foi encerrado e remediado. O estudo foi levado a cabo por meio de dados de monitoramento de recalqu

9. DELINEATION OF HOMOGENEOUS ZONES BASED ON GEOSTATISTICAL MODELS ROBUST TO OUTLIERS
RESUMO Diversas pesquisas utilizam medidas de condutividade elétrica aparente do solo (CEa) como indicador da variabilidade espacial de atributos físico-químicos existentes no campo de produção. Com base nestas medidas, zonas de manejo (ZM) são delineadas para aperfeiçoamento da gestão agrícola. Entretanto, estas amostras têm apresentado presença

10. Selection of a Hyper-Elastic Material Model - a Case Study for a Polyurethane Component
Abstract The aim of this study was to select an appropriate material model for a polyurethane rail pad. The considered material was assumed to be hyper-elastic, and model selection was limited only to the Mooney-Rivlin (M-R) material models available in the MSC.Marc/Mentat system. The selection of the most appropriate material model was based on the most acc

11. Organizações Outras: Diálogos Entre a Teoria da Prática e a Abordagem Decolonial de Dussel
Resumo O objetivo deste ensaio é propor um alinhamento teórico possível entre o aporte dos estudos decoloniais latino-americanos - com ênfase no trabalho de Enrique Dussel - e a abordagem teórico-metodológica da teoria da prática, partindo de um entendimento específico do debate centro/periferia para adentrar a forma de capturar as organizações em

12. Energy based collocation method to predict progressive damage behavior of imperfect composite plates under compression
Abstract A new collocation methodology is presented to predict failure and progressive damage behavior of composite plates in this paper. The present work deals with composite plates containing initial geometric imperfections and different boundary conditions under uniaxial in-plane compressive load. In the present study, the domain is discretized with Lege
