1. Study of Coffee Grounds Oil Action in PVC Matrix Exposed to Gamma Radiation: Comparison of Systems in Film and Specimen Forms
The poly (vinyl chloride), PVC, undergoes changes in its physicochemical properties when it is exposed to gamma radiation. Thus, the radiolytic stabilization of PVC is one way for obtain a material with radiation resistance. In this work, we studied the coffee grounds oil as PVC radiolytic protection in two systems forms: PVC film and PVC specimen. The syste

2. Efeitos da formação de classes de equivalência sobre a solução de problemas de adição e subtração / Some effects of equivalence class formation over the solution of addition and subtraction problems
Research has shown that some properties of the additive problem may cause difficulties to solve it. The most important are: the problems presentation form, the semantic structure and the position of the unknown. Two experiments were conducted with some methodological differences, but both with the aim of investigating if the formation of an equivalence class

5. Problemas de estruturas aditivas e multiplicativas propostos em livros didÃticos de matemÃtica: o impacto do Programa Nacional do Livro DidÃtico
This research presents an analysis of how additive and multiplicative problems are presented in Elementary School Mathematics textbooks. The aim of the study is to observe the impact that the PNLD, the Brazilian National Plan of Textbooks, has on the treatment given to the meanings of the arithmetic operations and the forms of symbolic representations presen

7. Análise do desempenho de alunos do ensino fundamental em jogos matemáticos: reflexões sobre o uso da calculadora nas aulas de matemática
This research aims to investigate what teaching strategies, considering the use of a calculator in the classroom can become more efficient perception of mistakes in handling additive and multiplicative between students in a 7th grade of elementary school, in the afternoon shift of a State School in Osasco city S.P. (Brazil). This study consisted of a qualita

8. Condições de solubilidade p-ádica para formas aditivas de grau ímpar
This work is based on articles of Tietäväinen and Low, Pitman and Wolff, where both investigate conditions for p-ádic solubility from additive forms, in n variables, of odd degree k. It is checked for a form that, if n [(log 2)−1k log k], then this form has non-trivial p-ádics zeros, for any prime p. Subsequently, we studied systems of R forms with

9. Estabilidade oxidativa de óleo extra-virgem de castanha do Pará com ervas aromáticas antioxidantes / Oxidative stability of crude Brazil nut oil whith antioxidant aromatic herbs
With the purpose to inhibit or to delay the lipid oxidation, oil, fats and fatty foods chemical composites are used known as anti oxidant. Recently, the interest in the additive addition in foods derived from plants has increased, in this way the us e of herbs and extracts has shown some preservation properties of health and foods. The rule of natural aromat

10. Avaliação in vivo e in vitro da citotoxicidade, genotoxicidade e dos efeitos protetores de extratos de plantas do cerrado brasileiro
The use of plants for healing purposes is becoming increasingly popular, as soon as they are believed to be beneficial and free of side effects. However, most of information available on several medicinal herbs does not have any scientific supporting data and their use as medicaments is based simply on traditional folk. Among the plants used by the humanity

11. ANÃLISE DE INFLUÃNCIA BASEADA NA CURVATURA NORMAL CONFORME PARA UM MODELO DE REGRESSÃO DIRICHLET
Neste trabalho apresentamos um estudo de influÃncia local no modelo de regressÃo Dirichlet proposto em Silva (2004) usando a curvatura normal conforme proposta por Poon &Poon (1999). Perturbamos o modelo segundo quatro esquemas de perturbaÃÃes diferentes, a saber: a log-verossimilhanÃa de forma multiplicativa, as variÃveis explicativas de forma aditiva

12. Quality of yellow passion fruit silage in the pure forms and in mixture with additives. / Qualidade da silagem do resÃduo do fruto de maracujà amarelo nas formas pura e em mistura com aditivos
Brazil possesses a huge amount of residues and by-products of agriculture and of agroindustry with potential of use in ruminant feeding. A few limitations may cause some of these additives to have a more restricted utilization, among them the low percentage of DM, which impairs ensiling process, demanding the adoption of procedures which modify that picture
