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. Finite element computational development for thermo-mechanical analysis of plane steel structures exposed to fire
Abstract This article presents a numerical formulation based on finite element procedures for application in nonlinear thermo-mechanical analyses of steel planar structures under fire condition. The mechanical properties of structural elements degrade when subjected to high temperatures, resulting in significant reductions in strength and stiffness. Under th

3. Prevalence of burnout and predictive factors among oncology nursing professionals: a cross-sectional study
ABSTRACT BACKGROUND: Burnout is a syndrome that mostly affects professionals working in contact with patients and their caregivers. In oncology care, nursing professionals are constantly required to provide emotional support for patients and their caregivers, throughout the process of becoming ill, suffering and dying. OBJECTIVE: To evaluate the prevalence

4. FEM-DEM simulation of Uniaxial Compressive Strength (UCS) laboratory tests
Abstract Finite/discrete element methods (FDEM) are hybrid numerical models that use algorithms to analyze the transition from continuous to discontinuous. This type of formulation allows modeling physical laboratory tests with greater proximity to reality. This article proposes to simulate the average behavior of a uniaxial compression test campaign. The te

5. Risk Factors for Mortality in Pediatric Cardiac Intensive Care Unit
The present study investigated the activity of pyrimidine derivatives against Aedes aegypti. Two compounds, 3c and 3d showed excellent larvicide activity. Additionally, quantitative structure-activity relationship (QSAR) models were built using multiple-linear regression and partial least squares with descriptors generated from Dragon and VolSurf+ software,

7. Aplicação do Formalismo CTP em uma Ação com Operador Pseudo-Diferencial
Resumo O formalismo CTP (closed-time-path) é uma ferramenta matemática para calcular funções de Green em sistemas físicos. A principal vantagem desta técnica é a de que, ao contrário do formalismo de Feynman, o formalismo CTP pode ser aplicado em sistemas fora do equilíbrio. Por outro lado, em física da matéria condensada, alguns modelos não loca

8. Structural models for analysis of reinforced concrete frame buildings with masonry infills
Resumo Este trabalho tem como objetivo o estudo do comportamento de pórticos de edifícios de concreto armado preenchidos com alvenaria frente às ações horizontais, empregando-se dois modelos estruturais: i) modelo de diagonal equivalente (MDE) e ii) modelo com elementos finitos bidimensionais para estado plano de tensões (MEF). No primeiro modelo, a al

9. Nonlinear numerical analysis of composite slabs with steel decking
Resumo O comportamento das lajes mistas é governado pelo cisalhamento longitudinal na interface entre o aço e o concreto, que é desenvolvido em lajes sob flexão simples. O método m-k e o método da interação parcial, utilizados no cálculo da resistência ao cisalhamento na interface aço-concreto de lajes mistas, são baseados em ensaios experimentai

11. Numerical Study on Response Characteristics of Solid Rocket Pintle Motor
ABSTRACT: Pintle technology is currently a versatile technology used in a solid rocket motor (SRM) to control the desired thrust by changing the nozzle throat area, while effectively controlling the chamber pressure at the same time. The sudden movement of the pintle can induce rapid changes in the flow field and the occurrence of pressure oscillations insid

12. Challenges in measuring angles between craniofacial structures
Abstract Objective: Three-dimensional (3D) angular measurements between craniofacial planes pose challenges to quantify maxillary and mandibular skeletal discrepancies in surgical treatment planning. This study aims to compare the reproducibility and reliability of two modules to measure angles between planes or lines in 3D virtual surface models. Methodol
