1. Quality of Stylosanthes Campo Grande seeds coated with different materials
ABSTRACT The seed coating technique adds value to the seeds. This technique allows changing the seed size and shape, facilitating sowing, and also the application of essential nutrients to the good development of the plant in the post-germination phases. Therefore, the objective of this work was to evaluate the physical and physiological characteristics of S

3. Pure line selection in a heterogeneous soybean cultivar
Abstract Although cultivars of autogamous plants are homogeneous genotypes, they may show natural variability due to mechanical mixing, natural hybridization, and mutation. The aim of the present study was to estimate genetic and phenotypic parameters and to identify and select superior genotypes that associate good performance in traits of interest from a h

4. Evaluation of the Acid Baking Technique to Decrease the Phosphorus Content of the Iron Ore
Unlike the available mineral resources, the steelmaking processes have demanded raw material with lower phosphorus content to decrease the costs, energy use, and the residue generated within the steel plant. One alternative is to develop pretreatment of the iron ore concentrates producing raw materials with lower phosphorus. Depending on the mineral structur

5. Developing a stepwise approach to simulate a hammer mill through the Whiten model - the adherence for a gold ore
Abstract Comminution represents a large portion of the capital and operating cost of a mineral processing plant. In 1983, Cohen estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to reduction of t

6. Isotopic variation among Amazonian floodplain woody plants and implications for food-web research
Isotopic variation within food sources adds uncertainty to models intended to reconstruct trophic pathways. Understanding this variation is pivotal for planning sampling protocols for food-web research. This study investigates natural variation in C and N stable isotopes among plant species in two western Amazon flooded forests with contrasting watershed bio

7. CFD modeling of two immiscible fluids mixing in a commercial scale static mixer
A Computational Fluid Dynamics model based on the Eulerian formulation for multiphase flow was developed to model the mixing hydrodynamics of two immiscible fluids in a commercial scale static mixer. The two immiscible liquids were condensate and caustic solutions and were considered as two phases that are interpenetrating each other. The aim of this study w

8. Biofertilizante de rochas mais matéria orgânica inoculada com bactéria diazotrófica na cana-de-açúcar.
Sugarcane (Saccharum spp.) Is currently considered one of the most important crops in the Brazilian social and economic. In Pernambuco, the sugar cane industry occupies an important agricultural area with high sugar and ethanol, generating many direct and indirect jobs. For increased productivity becomes necessary the use of management technologies that fost

9. Estudo de misturas asfálticas mornas em revestimentos de pavimentos para redução de emissão de poluentes e de consumo energético. / Study of warm mixes asphalt as a pavement surface for reducing polluants emissions and energy consumption.
In the last years there has been an increasing concern for the environment. In this context, warm mixes asphalt was developed with positive impact not only on the environmental pollution, but also on the energy consumption, due to the reduction of mixing and compaction temperatures. This work compares the behavior of warm mixes asphalts (with surfactant addi

10. Performance consequences of food mixing in two passion vine leaf-footed bugs, Holymenia clavigera Herbst, 1784 and Anisoscelis foliacea marginella Dallas, 1852 (Hemiptera : Coreidae) / Conseqüências da dieta mista na performance de dois coreídeos do maracujá, Holymenia clavigera Herbst, 1784 and Anisoscelis foliacea marginella Dallas, 1852 (Hemiptera : Coreidae)
Holymenia clavigera (Herbst) e Anisoscelis foliacea marginella (Dallas) (Hemiptera: Coreidae: Anisoscelini) ocorrem no sul do Brasil e são hóspedes de diversas espécies de Passifloraceae. Observações preliminares indicam uma alta coexistência destas espécies em termos de uso da planta hospedeira; em adição, ovos e ninfas são extremamente semelhante

11. Avaliação da qualidade de concretos produzidos em centrais dosadoras, misturados em caminhão betoneira e de concretos produzidos em centrais misturadoras / Evalution of quality of concrete produced in metering plant mixes in truck mixer and concret produced in mixed plant
Em razão do pouco número de estudos relacionados ao processo de produção do concreto dosado em central, no que tange ao tipo de mistura empregada, esta pesquisa busca contribuir com a avaliação da qualidade de concretos produzidos em centrais misturadoras e centrais dosadoras. O objetivo principal do trabalho foi o de verificar se a forma de mistura do

12. História natural e interação flores-besouros em espécies de Cerrado / Natural history and flower-beetle interactions in Cerrado species
Plant-animal interactions, such as pollination, are a key element in many terrestrial communities. The study of who interacts with whom is an important approach for understanding ecological and evolutionary processes. In some tropical communities, up to one quarter of all plant species may be pollinated by beetles. They are an ancient and much diversified in
