1. Impacto do uso de resíduo de vermiculita no estado endurecido de argamassas
Resumo No processo de beneficiamento da vermiculita é gerado um resíduo fino para o qual atualmente ainda não foi desenvolvida uma aplicação que possibilite a utilização em larga escala. Uma alternativa que vem sendo estudada é a associação com cimento Portland em composições de argamassas e concretos, em função da composição química do res�

5. River level sensitivity to SOI and NAO in Pantanal and Amazonia.
Water level in rivers of central and northern South America (SA) is primarily driven by fluctuations in rainfall that is largely controlled by regional and global sea-air-land interactions. In this work it is evaluated the role of changes in equatorial Pacific and north Atlantic ocean-atmospheric interactions in regulating river level in Pantanal and Amazoni

6. Avaliação da associação de clorexidina com etanol na durabilidade da adesão à dentina / Evaluation of the adjunctive use of chlorhexidine and ethanol on the durability of resin dentin bonds
Both adhesive and collagen degradation have been regarded as major causes of resin-dentin bonds failures over time. Complete infiltration of hydrophobic resins facilitated by ethanol, and the presence of MMPs inhibitors within the hybrid layer would build the ideal interface, resistant to hydrolysis and enzymatic activities. This study examined the benefits

7. Propriedades estruturais, microestruturais e elétricas da cerâmica BaSnO3 / Structural properties, the microstructural and electrical ceramics BaSnO3
The surface properties of ceramic powders play an important role in the production of devices of high quality, high performance and reliability. Many of these properties are related to interactions with the environment. One example, ceramics are used in gas sensor devices. A ceramic material that has been reported as promising gas sensor is perovskite BaSnO3

8. Orchidaceae nativas da região central de São Paulo, Brasil : florística, interação com forófitos, proposta de novas espécies e propagação in vitro de uma espécie ameaçada de extinção / Native Orchidaceae of the central region of São Paulo, Brazil: floristic, interaction nested with host tree, new species proposed and in vitro propagation of threatened of extinction species
Aiming to know the sorts of Orchidaceae of the central region of the State of São Paulo, from 1996 and more intensively from 2005, visits were carried out in 125 forest fragments of 23 local municípios, with weekly periodicity and also, fortnightly. The collect were assistematics, being each fragment visited in the biggest number of points. The species not

9. Geografia da saúde e geologia médica como instrumentos de planejamento e gestão em saúde ambiental : o caso das anomalias de flúor e da fluorose dentária em Itambaracá-Pr
Diverse are the interactions between the environment and the man, what certainly it is reflected in the health. It is enough to consider that the basic elements to our survival nothing more are of that the suitable environment to our consumption, as the water and foods, as well as air, which would have to be consumed by us free of interference human being, u

10. Functional properties of egg white proteins of quail egg / Propriedades funcionais de proteínas da clara do ovo de codorna
In this work, the functional characteristics of solubility, capacity of foam formation and gelation of the egg white proteins of quail egg were studied. Solubility data were evaluated in function of the stirring time of the proteic solution, the pH value and the salt concentration (NaCl), at 25 C. The foam and gelation properties were analyzed as a function

11. Estudo de monocamadas fosfolipidicas nanoestruturadas obtidas por LB para aplicações em biossensores
There has been long-standing interest in the physical chemical properties of defined mixtures of cholesterol and phospholipids in monolayer and bilayer membranes. They also provide insight into certain properties of the membranes of animal cells. Even if phospholipids and sphingolipids build up the matrix of cellular membranes, sterols are essential componen
