1. Quimiometria III - Revisitando a análise exploratória dos dados multivariados
In this work, three methods for pattern recognition, used as exploratory data analysis, are revisited. A brief review of principal component analysis, PCA, an unsupervised method, is provided. Next, the Mahalanobis distance and the confidence ellipses usually drawn around the scores samples are discussed. Fisher’s canonical variate analysis (a supervised m

2. Central Auditory Processing and Cognitive Functions in Children
Abstract Introduction Nowadays, there is no consensus on whether central auditory processing disorder is a primary or a secondary deficit to other cognitive deficits. A better understanding of the association between cognitive functions and central auditory skills may help elucidate this dilemma. Objective To investigate possible associations between audit

3. Adaptability and stability of maize genotypes in growing regions of central Brazil
ABSTRACT This study aimed to estimate and compare parameters of adaptability and stability for maize grain yield in a variety of environments by different projection methods. Data from experiments on 36 maize genotypes, in simple lattice 6x6, in 2012/13 season performed at nine growing locations in central Brazil were used. Adaptability and stability analyse

4. Interaction of Pb, Ni and Cd with Aquatic Humic Substances of Amazonian Blackwater Rivers
In this study, the extraction and characterization of aquatic humic substances (AHS) from two blackwater rivers in the Amazon basin was carried out in order to assess the seasonal effects in the AHS structure. In addition, an investigation of the complexing capacities (CC) of the structures containing the metal ions CdII, NiII and PbII was also done. The cha

6. Coexistence of low levels of HBsAg and high levels of anti-HBs may increase risk of hepatocellular carcinoma in chronic hepatitis B patients with high HBV load
ABSTRACT Objective: The clinical significance of coexistence of HBsAg/anti-HBs in chronic hepatitis B (CHB) patients remains controversial. This study was aimed to assess the association of this serological pattern with hepatocellular carcinoma (HCC) in patients with CHB. Methods: In this cross-section study, 206 CHB patients with coexistence of HBsAg/anti

8. Effects of extrinsic feedback on the motor learning after stroke
Abstract Aim: This study aims to investigate the effects of the type of extrinsic feedback provided equally in terms of timing and frequency of delivery on the motor learning after stroke. Methods: Twenty post-stroke individuals were distributed randomly into two groups according to the type of feedback provided: knowledge of performance experimental gro

11. A COMPARISON OF NONLINEAR MODELS FOR DESCRIBING WEIGHT-AGE DATA IN ANGLO-NUBIAN DOES
RESUMO Objetivou-se avaliar a idade da pesagem e a qualidade do ajuste de modelos não lineares a dados longitudinais para descrever o padrão de crescimento de fêmeas Anglonubiana. Pesos de 104 animais do nascimento até 60 meses de idade, foram agrupados em 10 classes, com intervalos de seis meses. Em cada classe estimou-se parâmetros A, B e K com modelo

12. Genetic Population Structure and Allele Surfing During Range Expansion in Dynamic Habitats
Abstract: Expanding populations may loss genetic diversity because sequential founder events throughout a wave of demographic expansion may cause “allele surfing”, as the alleles of founder individuals may propagate rapidly through space. The spatial components of allele surfing have been studied by geneticists, but have never been investigate on dynamic
