13. Weld-metal property optimization from flux ingredients through mixture experiments and mathematical programming approach
This paper presents a new methodology for weld-metal properties optimization from welding flux ingredients. The methodology integrates statistical design of mixture experiment with mathematical programming optimization technique. The mixture experiment is responsible for the modeling of the weld-metal properties as a function of welding flux levels while mat

14. Evaluation of the atmospheric pollution dispersion s scenarious for the Paraíba river valley / Avaliação de cenários de dispersão de poluentes atmosféricos para o Vale do Rio Paraíba
This work was carried out a comprehensive assessment of the performance of the direction of winds, near the surface (1000 hPa), and its predominance in the region of Paraíba River Valley, from 10 cities located along the region of Paraíba River Valley. Furthermore, different scenarios were evaluated for dispersion of air pollutants for the region of Paraí

15. Relation between the Antarctic Sea ice concentration and low temperatures in South America / Relação entre a concentração de gelo marinho Antártico e a temperatura mínima na América do Sul
The Antarctic Sea Ice Concentration (ASIC) is thought to be an important element in the analysis of the world climate. However, few studies have investigated its relation to other climatic elements. Thus, the aim of this study was to verify the relation between the ASIC and low temperatures in South America through two approaches. The first, regional, invest

16. Sustainability concept: structural change characteristic loss / Sustentabilidade: a perda do caráter de mudança estrutural do conceito
This work aims to study the epistemological concept of environmental sustainability through Cartesian and economic theoretical paradigms. This analysis guides the modern society development, which causes deterioration on social and environmental fields. It also includes the environmental history study, which expresses, over time, different sustainability con

17. Da raiz ao fruto da contemporaneidade : Carpinejar e a sede de ser e ter uma prole
The poetry of Fabrício Carpinejar permeates the fragmentation of self and the de-referentialization experienced by the subject behind the lyrical self, which makes him one of the poets that best represents postmodernity. Considering that perspective, we analyze in detail the issue posed by the prefix de- in two of his works, Um terno de pássaros ao sul e M

18. Formação do agente indígena de saúde: processo reflexivo com perspectiva de uma abordagem da integralidade e de um currículo intercultural / The Indigenous Health Agent Educational Back-ground: a reflexive process by an approaching perspective for the integrality of and an intercultural curricullum
Based on the presupposition that the Indigenous Health Agent needs to take into ac-count intercultural elements in his/her pedagogical practice and be guided by integral health contents when promoting and protecting health, this investigation was carried out in order to analyze the reflexive process in the professional qualification of an Indigenous Health A

19. Desenvolvimento e aplicação de um novo ensaio para a determinação eletroquímica da capacidade antioxidante de compostos modelo e de matrizes complexas / Development and application of a new assay for the electrochemical determination of the antioxidant capacity of model compounds and of complex matrices
This work describes the development and practical applications of a novel and simple electrochemical methodology for the determination of the antioxidant capacity of specific model molecules and/or some complex food samples currently consumed in Brazil. Other systems having either theoretical or technological interest were also investigated. The method is ba

20. Do global ao local: percursos teÃricos e conceituais da sustentabilidade
Sustainabilityâs discussion is fertile and controversial. Authors have different opinions about this issue, and it always treated in conjunction with the discussion of sustainable development. Our initial hypothesis is that the explicitness failure about SD, was linked to the difficult to comprehend the term sustainability. After that, we observe that was n
