1. New Europium(III)-TTA Complex Containing 2-Pyrrolidone as Coligand to Application as Luminescent Sensor: PbII and Ethanol in Gasoline
This work describes the synthesis and application of an europium(III) complex, [Eu(TTA)3(2-pyr) (H2O)], containing 2-thenoyltrifuoroacetonate (TTA) and 2-pyrrolidone (2-pyr) as ligands, obtained as white solid and soluble in ethanol. In solution, the complex showed red emission, characteristic of the EuIII emission in the solid state (λexc = 375 nm and λem

2. Galbraith, Robert. O Chamado do Cuco. Tradução de Ryta Vinagre. Rio de Janeiro: Rocco, 2013. 448 p.
ABSTRACT BACKGROUND: Environmental and population characteristics seem to influence the variation in cutoff points of the Short Physical Performance Battery (SPPB) for diagnosing frailty syndrome among older adults. OBJECTIVE: To verify the validity of the SPPB for screening for frailty syndrome among older adults in the Amazonian context. DESIGN AND SETT

4. Synthesis and Evaluation of the Fungal Activity of New Pyrazole-Carboxamides against Colletotrichum gloeosporioides
The pyrazole core has been recognized by their biological properties and included in the synthesis of modern agrochemicals. Part of these studies consists of making structural modifications to pesticides for commercial purposes to increase efficacy. In this article, we present the synthesis of four new pyrazol-4-carboxamide 8a-8d derivatives (PCD), through a

5. AVALIAÇÃO DE NANOTUBOS DE CARBONO FUNCIONALIZADOS VISANDO O DESENVOLVIMENTO DE MÉTODOS DE PRÉ-CONCENTRAÇÃO DE ÍONS METÁLICOS E DETERMINAÇÃO POR TÉCNICAS ESPECTROMÉTRICAS E ELETROANALÍTICAS
This review focuses on the use of functionalized carbon nanotubes (CNTs) on the development of preconcentration methods with substantial contributions on selectivity and sensitivity for metal ions determination. CNTs have been usually employed in the development of preconcentration/speciation coupled to spectroanalytical techniques for ions determination at

6. Factorial validity and measurement invariance of the uncertainty response scale
Abstract This study presents the adaptation of the Uncertainty Response Scale (Greco & Roger, Pers. Individ. Differ, 31:519-534, 2001) to Portuguese. This instrument was administered to a non-clinical community sample composed of 1596 students and professionals, allowing a thorough validity and invariance analysis by randomly dividing participants into three

7. Dendroecologia de Gymnanthes klotzschiana Müll. Arg. em um remanescente de Floresta Ombrófila Mista Aluvial no Sul do Brasil
Resumo Em um remanescente de Floresta Ombrófila Mista Aluvial, foram abatidas 56 árvores adultas de Gymnanthes klotzschiana, árvore típica e representativa desta formação e popularmente conhecida como branquilho, às margens do rio Barigui, em Araucária - PR, o qual teve o curso de seu leito retificado na década de 1960. Considerando-se as técnicas

9. Suficiência amostral para avaliação da fauna epiedáfica com o método Provid
Resumo O solo é habitado por milhares de organismos responsáveis por diversas funções e processos no ecossistema. Por apresentar uma grande sensibilidade às modificações do meio, a fauna do solo é considerada um bom bioindicador de qualidade do solo. Entretanto, uma amostragem inadequada pode inviabilizar sua utilização em estudos de impacto ambien

10. Carbon indices to assess quality of management systems in a Subtropical Acrisol
ABSTRACT: Management systems to improve soil quality are essential for agricultural and environmental sustainability. We assessed the quality of soil management systems applied to a subtropical Acrisol in terms of the carbon management index (CMI), the stratification ratio for total organic carbon (SR-TOC) and light fraction of organic matter (SR-LF). In add

11. Preprocessing procedures and supervised classification applied to a database of systematic soil survey
ABSTRACT: Data Mining techniques play an important role in the prediction of soil spatial distribution in systematic soil surveying, though existing methodologies still lack standardization and a full understanding of their capabilities. The aim of this work was to evaluate the performance of preprocessing procedures and supervised classification approaches

12. A predictive multimetric index based on macroinvetebrates for Atlantic Forest wadeable streams assessment
Resumo: Índices Multimétricos (MMIs) são ferramentas amplamente aplicadas ao monitoramento ecológico de ecossistemas aquáticos continentais. A maior dificuldade na utilização dos MMIs em amplas escalas espaciais consiste no aumento da variabilidade ambiental associado ao aumento da escala. A covariância entre os impactos antropogênicos e o gradiente
