1. Analytical method validation for the identification and quantification of dissolved gold and gold nanoparticles in cosmetics products by single particle inductively coupled plasma mass spectrometry
Nanoparticle (NP) applications have recently gained more space in the development of many products, especially in cosmetology. The aim of the present study was to validate a single particle inductively coupled plasma mass spectrometry technique for the detection and quantification of gold nanoparticles (AuNPs) and gold ions (Au (i)) in different cosmetics cu

2. Genetic diversity in F3 population of ornamental peppers (Capsicum annuum L.)
ABSTRACT Peppers belong to the Solanaceae family and present a wide genetic variability that may be accessed through phenotypic and genotypic traits. This work aimed to study the genetic divergence in an ornamental pepper F3 population by multivariate methods based on the individual and simultaneous analyses of qualitative, quantitative, and molecular data.

3. Gait and functionality following unilateral and bilateral hip replacement
Resumo Introdução: A Artroplastia Total de Quadril (ATQ) é um procedimento cirúrgico utilizado para minimizar sintomas gerados por patologias ortopédicas, como a osteoartrite. Ressalta-se que não há concordância se os parâmetros da marcha são restaurados após a cirurgia. Objetivo: Comparar os parâmetros espaço-temporais e funcionalidade da mar

4. Soil physical and hydraulic properties in the Donato stream basin, RS, Brazil. Part 1: Spatial variability
RESUMO Os processos de fluxo e armazenamento de água no solo estão diretamente associados às suas propriedades hidráulicas, as quais podem variar significativamente no espaço. Por estas razões, este trabalho objetivou realizar uma análise espacial da condutividade hidráulica saturada e dos parâmetros da curva de retenção de água no solo na bacia

5. Wet Days in the Dry Quarter of the Alcântara Launch Center Region: Observational Features
ABSTRACT: Precipitation events are infrequent in the dry quarter (SON) of the Alcântara Launch Center (Centro de Lançamento de Alcântara, CLA), the main launch site of the Brazilian Space Program. However, their occurrence could be a risk for activities during launch missions. In this work, the observational features of wet days (daily precipitation total

6. SPACE DISTRIBUTION OF SOYBEAN SEED STORAGE POTENTIAL
RESUMO Objetivou-se identificar a distribuição espacial da qualidade fisiológica de sementes de soja durante o armazenamento, provenientes de campo de produção de 39 hectares por meio de técnicas de geoestatística na safra 2012/2013. Realizou-se amostragem de sementes em pontos georreferenciados, para a determinação da qualidade fisiológica e anál

7. Variabilidade dos casos de malária e sua relação com a precipitação e nível d’água dos rios no Estado do Amazonas, Brasil
O entendimento das relações entre as variáveis de precipitação e nível d’água dos rios com os casos de malária podem fornecer indícios importantes da modulação da doença no contexto da variabilidade climática local. No intuito de demonstrar como essas relações variam no mesmo espaço endêmico, realizou-se a análise de coerência e fase de

8. Prediction of Topsoil Texture Through Regression Trees and Multiple Linear Regressions
ABSTRACT: Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear R

9. Populational brain models of diffusion tensor imaging for statistical analysis: a complementary information in common space
Abstract Introduction: The search for human brain templates has been progressing in the past decades and in order to understand disease patterns a need for a standard diffusion tensor imaging (DTI) dataset was raised. For this purposes, some DTI templates were developed which assist group analysis studies. In this study, complementary information to the most

10. REGIONALIZATION OF MAXIMUM AND MINIMUM FLOW IN THE TELES PIRES BASIN, BRAZIL
ABSTRACT In a watershed there is space and climate variability within its catchment area, causing changes in water qualitative and quantitative characteristics. Thus, the hydrological data collected from a specific basin may be extrapolated to neighboring basins with similar physical characteristics, using techniques of hydrological regionalization. This stu

11. Spatial and Temporal Variability of Soil CO2 Flux in Sugarcane Green Harvest Systems
ABSTRACT The sugarcane green harvest system, characterized by mechanized harvesting and the absence of crop burning, affects soil quality by increasing crop residue on the soil surface after harvest; thus, it contributes to improving the physical, chemical, and microbiological properties and influences the soil carbon content and CO2 flux (FCO2). This study

12. Variabilidade espacial da uniformidade da lÃmina de Ãgua aplicada por sistemas fixos de irrigaÃÃo por aspersÃo / Spatial variability of water level uniformity applied by fixed sprinkler irrigation systems
Water application uniformity is an important factor to be considered in the evaluation of sprinkler irrigation systems. The uniformity depends on the type of sprinkler and its operational conditions, the display and space among the sprinklers on the field, and also the wind speed and direction during the water applying period. This work contributes to develo
