13. Metodologia para uso de simulação física no estudo da ZAC e na obtenção de diagramas CCT para soldagem / The Use of Physical Simulation on HAZ Study and CCT Diagram Attainment Dedicated to Welding
The joining of metals is often associated to metallurgical problems. Specifically, metallurgical transformations in the HAZ (Heat Affected Zone) can occur, what lead to undesirable microestructural changes. The HAZ is a difficult region for studying due to its small dimensions and high thermal gradientes. Thus, in order to overcome this limitation of the HAZ

14. Conjunto dos números irracionais: a trajetória de um conteúdo não incorporado às práticas escolares
The main objective of this work is to investigate the difficulties that appeared along the history for the development of the mathematical content irrational numbers and which are the approaches present in the text books. The subject irrational numbers is considered important in the basic education of Mathematics and it comes for the students, in the text bo

15. Qualidade e atividade antioxidante total de pedÃnculos de clones comerciais de cajueiro anÃo precoce / Quality and activity total antioxidant capacity of penduncles of commercial grain stalks of clones of dwarf cashew apple tree.
Cashew has big importance in Brazilian culture of fruits, principally in Northwest region, presenting very expressive social and economic activity. Accordingly to some studies cashew apple has a high vitamin C, carotenoids and phenolics compounds contents. More than vitaminic potential, these compounds have antioxidant potential to cashew pulps. This work ai

16. Igrejas setecentistas mineiras : a influencia das caracteristicas arquitetonicas na qualidade acustica / The influence of architectural characteristics on acoustic quality of churches of Minas Gerais State built in the 1700s´s
The Vatican Council II constitution promoted deep changes in Catholic Church and the mass liturgy, in which one can highlight the use of the national language instead of Latin. This transformation together with the growing participation followers in the celebrations was responsible for changes in habits and consequently use of these places concerning acousti

17. A ética do discurso entre a validade e a factibilidade
Karl-Otto Apel and Jürgen Habermas have shared the attempt to found ethics in terms of the philosophy of language, which they have called discourse ethics. Such an attempt aims to face the paradoxical situation posed by our times: on the one hand, the need for universal ethics that is, one that could be binding for all mankind has never been more urgent; ho

18. Estudo sobre programas de educação ambiental no Brasil e a questão da sustentabilidade ambiental
In this research, the joint of the Environmental Education is analyzed under the parameters of the sustainable development, defined as those that identify and evaluate the transformations of the social processes in the direction of the Environmental conservation and human promotion. According to this study, these parameters are: the ecological, the social, t

19. Estudo sobre programas de educação ambiental no Brasil e a questão da sustentabilidade ambiental
Environmental Education also analyzed, was shown that the majority possess, of direct or indirect form, strong governmental participation, either in the management or in the financial support. The parameters analyzed in the programs had been restricted or limited to the communitarian actions, presenting a clever Environmental Education, but it cannot achieve

20. Aplicação da descrição cinemática co-rotacional na análise não-linear geométrica de estruturas discretizadas por elementos finitos de treliças, vigas e cascas / The application of the co-rotational kinematic description to the geometrically non-linear analysis of structures modeled by truss, beam and shell finite elements
The co-rotational formulation was used as the kinematic description to evaluate the geometrically non-linear behavior of different types of structures on a static analysis. Along the current research, it was aimed to demonstrate the basic concepts of the co-rotational approach that is based on the separation of the total motion into rigid body and deformatio

21. Modelagem analítico-estocástica de doenças priônicas
In this work one studies several characteristics of the so called prionic diseases, a pathogeny caused by protein molecules, known as Prions. Prions can exist in two different molecular conformations. The first of these, known as PrPC, is normally found in mammals, whilst the second, known as PrPSc, is the rare pathogenic form, responsible for the developmen

22. STUDY OF THE STRUCTURAL AND MAGNETIC PROPERTIES OF Zn1-xMnxIn2Se4 SYSTEM / ESTUDO DAS PROPRIEDADES ESTRUTURAIS E MAGNÉTICAS DO SISTEMA Zn1-xMnxIn2Se4
This work reports a systematic study on the crystal growth and magnetic and structural properties of the diluted magnetic semiconductors (SMD) Zn1-xMnxIn2Se4. Crystals with Mn concentrations $0leqslant xleqslant 1.00$ were grown by chemical vapour transport (CVT). Through x-ray powder diffraction patterns and Laue diagrams of single crystal we studied the tr

23. The associated Planting among banana (Musa acuminata cv. Big it Sleeps) and "feijão-de-porco" (Canavalia ensiformis (L.) D. C.): an agronomic evaluation of the effects of the competition for water, nitrogen and luminous energy / O plantio associado entre banana (Musa acuminata cv. Grande Nane) e feijão-de-porco (Canavalia ensiformis (L.) D. C.): uma avaliação agronômica dos efeitos da competição por água, nitrogênio e energia luminosa
In tropical regions, intensive banana (Musa accuminata) monocropping has severe agronomic and environmental impacts, and the sustainability of this production is actually highly compromised. Yield reductions are principally due to the decrease of soil fertility and root systems damages by sod fungus and nematodes. Several alternatives actually aim to improve

24. Analise do hidrograma unitario geomorfologico e regionalização do parametro de velocidade
The greatest part of problems about the determination of a hydrogram project occurs on non-monitored basins and therefore without data to permit the co-relation of the rain with the exit hydrogram. This problem can be overcome through the transformation of the rain into water evacuation by a mathematical model generated from basins with similar characteristi
