13. Fatigue Life and Residual Strength prediction of GFRP Composites: An Experimental and Theoretical approach
Abstract This paper presents the fatigue behavior of Glass Fiber Reinforced Polymer (GFRP) composites at constant amplitude tension-tension loading conditions. A two parameter residual strength and fatigue life model has been proposed by accounting the effect of stress ratio when the structure undergoes continuous loading. A model is also developed to predic

14. Validation and reliability of the rapid diagnostic test ‘SD Bioeasy Dengue Duo’ for dengue diagnosis in Brazil: a phase III study
BACKGROUND The diagnosis of dengue is complex. Until recently, only specialised laboratories were able to confirm dengue infection. However, this has changed with the newly available immunochromatographic rapid tests. Early diagnosis is of great interest, and point-of-care rapid tests have been increasingly used in Brazil. Most of those tests have not under

15. On the Free Vibration Analysis of Laminated Composite and Sandwich Plates: A Layerwise Finite Element Formulation
Abstract In this paper, a new higher-order layerwise finite element model, developed earlier by the present authors for the static analysis of laminated composite and sandwich plates, is extended to study the free vibration behavior of multilayer sandwich plates. In the present layerwise model, a first-order displacement field is assumed for the face sheets,

16. Harmony in Life Scale - Turkish version: Studies of validity and reliability
Abstract This article presents the adaptation and psychometric evaluation of the Turkish version of Harmony in Life Scale (Turkish-HiL). The present paper investigates (study 1; N 1 = 253) confirmatory factor analysis, measurement invariance; (study 2; N 2 = 231) concurrent validity; (study 3; N 3 = 260) convergent and known-group validities; (study 4; N t �

17. A validation study of the Multidimensional Life Satisfaction Scale for Children
Abstract Introduction Recent studies on the life satisfaction in children and young people have investigated its association with vulnerability, discrimination, the individual’s school environment and network of relationships, and mental health. The growing interest in the area demands instruments with good psychometric properties. Aim The aim of this

18. Validation and Invariance of the Dental Anxiety Scale in a Brazilian sample
Abstract: The aim of this study was to evaluate the properties of the Dental Anxiety Scale (DAS) when applied to Brazilian adults and to test its invariance across independent samples and different sociodemographic groups. Sociodemographic data, reports on previous unpleasant dental experiences and DAS responses were collected through telephone interviews. M

19. Reliability, failure probability, and strength of resin-based materials for CAD/CAM restorations
ABSTRACT Objective: This study investigated the Weibull parameters and 5% fracture probability of direct, indirect composites, and CAD/CAM composites. Material and Methods: Discshaped (12 mm diameter x 1 mm thick) specimens were prepared for a direct composite [Z100 (ZO), 3M-ESPE], an indirect laboratory composite [Ceramage (CM), Shofu], and two CAD/CAM co

20. Determinants of quality of life in Brazilian patients with myasthenia gravis
OBJECTIVES: The aims of the current study were 1) to evaluate the reliability and validity of the Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale and 2) to investigate the quality of life of Brazilian patients with myasthenia gravis and its determinants. METHODS: This cross-sectional study included 69 patients with myasthenia gravi

21. Severity of temporomandibular disorders in women: validity and reliability of the Fonseca Anamnestic Index
The aim of this study was to assess the validity and reliability of the Fonseca Anamnestic Index (IAF), used to assess the severity of temporomandibular disorders, applied to Brazilian women. We used a probabilistic sampling design. The participants were 700 women over 18 years of age, living in the city of Araraquara (SP). The IAF questionnaire was applied

22. Medindo valores com parcelas de itens: contribuições à teoria funcionalista dos valores / MEASURING VALUES WITH ITEM PARCELS: CONTRIBUTIONS TO FUNCTIONAL THEORY OF VALUES
ABSTRACT - The current thesis aimed to create a new instrument for measurement of human values, based on the functionalist theory of human values, for diagnosis and screening. To this end, it took out three studies. Study 1 aimed to build up a database of items that would meet an essential criterion: to represent the subfunctions recommended by the functiona

23. Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) and for four full-scale beam bending tests. The accuracy of analytical design equations is evaluated by comparing their predictions with e

24. A first attempt towards reliability-based calibration of Brazilian structural design codes
This paper addresses the reliability-based calibration of partial safety factors for Brazilian design codes NBR8681:2003 (Actions and Safety of Structures) and NBR8800:2008 (Design of Steel and Steel-Concrete Composite Structures). To the author's knowledge, these codes have never been subject to reliability-based calibration of partial and load combination
