1. Epidemiological, neurofunctional profile and prevalence of factors associated with the occurrence of physical disabilities due to leprosy in a reference center in Northeast Brasil: a sectional study
SUMMARY OBJECTIVE: To describe the epidemiological and neurofunctional profile, as well as the prevalence of factors associated with the occurrence of physical disabilities due to leprosy in a reference center in Northeast Brasil. METHODS: A cross-sectional study including 50 leprosy patients diagnosed in Juazeiro-Bahia. Variables analyzed: sex, age, his

2. Neuroimaging of intrinsic connectivity networks: a robust method for assessing functional brain organization in psychiatric disorders
Objective: German psychiatrist Kurt Schneider proposed the concept of first-rank symptoms (FRS) of schizophrenia in 1959. However, their relevance for diagnosis and prediction of treatment response are still unclear. Most studies have investigated FRS in chronic or medicated patients. The present study sought to evaluate whether FRS predict remission, respo

3. The latent structure and reliability of the emotional trait section of the Affective and Emotional Composite Temperament Scale (AFECTS)
Abstract Background The Emotional and Affective Composite Temperament (AFECT) model describes originally six traits of volition, anger, inhibition (fear and caution subordinate factors), control, sensitivity, and coping. However, fear and caution have shown opposite relatioships with criteria-variables, indicating factor independence. Objective The curre

4. Indirect estimation of infant mortality in small areas*
Resumo Métodos indiretos do tipo Brass para estimar a mortalidade nas primeiras idades da vida têm sido usados por mais de quatro décadas, fornecendo estimativas muito robustas para países que não possuem sistemas confiáveis de estatísticas vitais. No entanto, quando as áreas de estimativa são pequenas, o número de crianças mortas pode ser muito b

5. ESTIMATION OF PARAMETERS AND STATES USING A BAYESIAN PARTICLE FILTER FOR THE SULFATE ION ADSORPTION PROCESS IN A FIXED BED COLUMN
Abstract Ensuring that industrial effluents meet quality standards to be released into water bodies is still one of the major environmental concerns. Liquid phase adsoption in fixed bed collumns is one of the most known treatments. Measurements are needed to monitor the process. However, as they are often corrupted by noise from the measuring equipment, perf

6. Application of quality by design approach in RP-HPLC method development for simultaneous estimation of saxagliptin and dapagliflozin in tablet dosage form
A simple, sensitive, precise, accurate and robust high performance liquid chromatographic method has been developed for simultaneous estimation of saxagliptin (SAXA) and dapagliflozin (DAPA) in pharmaceutical formulation. Design of experiments (DoE) was applied for multivariate optimization of the experimental conditions of RP-HPLC method. Risk assessment wa

7. Application of the Respondent-Driven Sampling methodology in a biological and behavioral surveillance survey among female sex workers, Brazil, 2016
RESUMO Introdução: O método de amostragem Respondent-Driven Sampling (RDS) tem sido utilizado em inquéritos com populações-chave sob maior risco de infecção pelo HIV, como as mulheres trabalhadoras do sexo (MTS). Este artigo tem o objetivo de descrever a implementação do RDS entre MTS em 12 cidades brasileiras em 2016. Metodologia: Trata-se de um

8. Socioeconomic inequalities in breast cancer mortality in microregions of the Brazilian Northeast
Resumo Objetivos: avaliar a relação entre as taxas corrigidas de mortalidade por câncer de mama e indicadores de condições de vida das idosas das microrregiões do Nordeste brasileiro. Métodos: adotou-se um estudo ecológico nos anos de 2010 e 2015 para as 188 microrregiões do Nordeste utilizando a modelagem de equações estruturais. Os dados de po

9. Robust volumetric models for supporting the management of secondary forest stands in the Southern Brazilian Atlantic Forest
Abstract The majority of Atlantic Forest fragments in Southern Brazil are second-growth forests dominated by fast-growing species with considerable market-value timber. Nevertheless, volume prediction models are scarce, especially to estimate tree total volume (i.e., stem plus branches). This study approached the issue through the following aims: to fit and

10. Slash Spatial Linear Modeling: Soybean Yield Variability as a Function of Soil Chemical Properties
ABSTRACT: In geostatistical modeling of soil chemical properties, one or more influential observations in a dataset may impair the construction of interpolation maps and their accuracy. An alternative to avoid the problem would be to use most robust models, based on distributions that have heavier tails. Therefore, this study proposes a spatial linear model

11. Estudio de Aplicación del Análisis Regional de Frecuencias Basado en L-Momentos al Caso de las Precipitaciones Anuales en la Provincia de Camagüey, Cuba
Abstract In this research is presented a case study of application of the procedure known as Regional Frequency Analysis based on L-moments, in the study of the annual rainfall in the province of Camagüey, Cuba. It has adopted the above methodology to be statistically robust procedure to compensate for the lack of long-standing historical records for its ab

12. Estabilidad de la estimación de la onda anual en escala diaria de la temperatura
The choice of estimation of deterministic effect method in climate series is usually the starting point for most studies on climate variability. This decision is more sensitive when the presence of nonlinear phenomena is explored. Therefore, this paper analyzes the robustness and stability of different methods to estimate the annual cycle in time series of d
