13. Residual Stress Evaluation by X-Ray Diffraction and Hole-Drilling in an API 5L X70 Steel Pipe Bent by Hot Induction
The API 5L X70 steel is used in high-pressure gas transmission pipelines. Because of this, knowledge of presence of residual stress and their magnitude is important to assess the material integrity in service. For the pipeline manufacturing, tubes need to be curved which is often made using the hot induction bending process. This process can introduce differ

14. Annual tree rings in Piptadenia gonoacantha (Mart.) J.F.Macbr. in a restoration experiment in the Atlantic Forest: potential for dendroecological research
ABSTRACT The tree Piptadenia gonoachantha is widely used in forestry and in forest restoration projects, which require methods for evaluating tree growth. Long-term studies are necessary to determine patterns and detect changes in species growth rhythms. Tree ring analysis provides a precise method for determining age and documenting long-term growth trends

15. Applications of electronic noses in meat analysis
Abstract Electronic noses are devices able to characterize and differentiate the aroma profiles of various food, especially meat and meat products. During recent years e-noses have been widely used in food analysis and proved to provide a fast, simple, non-expensive and non-destructive method of food assessment and quality control. The aim of this study is t

16. Bladder response to acute sacral neuromodulation while treating rats in different phases of complete spinal cord injury: a preliminary study
Background: Compared to conventional therapies, sacral neuromodulation (SNM) may offer an alternative, non-destructive treatment for SCI patients with bladder dysfunction. Understanding bladder response to SNM treatment for SCI in different phases may yield new insights for innovative use of this promising technique. Materials and Methods: Female Sprague-D

17. Estimation of leaf area in coffee leaves (Coffea arabica L.) of the Castillo® variety
Allometric models based on measurements of single leaf dimensions or a combination there are useful tools for determining individual leaf area (LA) because they are non-destructive, precise, simple and economical methods. The present study was carried out at the Central Station Naranjal of Cenicafé, located in the Department of Caldas (Colombia), four model

18. Métodos para resgate, conservação e multiplação em larga escala de matrizes de Eucalyptus benthamii Maiden &Cambage / Methods for rescue, conservation and multiplication of matrices Eucalyptus benthamii Maiden &Cambege
The E. benthamii presents a great aptitude for cultivation in Brazil, especially in cold climates and with frequent frosts, this is due to your west of Sydney origin in Australia, where temperatures are very low, with frosts. Taking into account their optimal silvicultural performance, selected genotypes will certainly represent an excellent alternative for

19. A fault location method using Lamb waves and discrete wavelet transform
Non-destructive evaluation methods and signal process techniques are important steps in structural health monitoring systems to assess the structure integrity. This paper presents a method for fault location in aluminum beams based on time of flight of Lamb waves. The dynamic response signal captured from the structure was processed using the discrete wavele

20. Aplicação de métodos não destrutivos para qualificação de combustíveis tipo dispersão de U308-Al e U3Si2-Al no reator IEA-R1 / Application of non-destructive methods for qualification of the U3O8-Al and U3Si2-Al dispersion fuels in the IEA-R1 Reactor
IPEN/CNEN-SP manufactures fuels to be used in its nuclear research reactor the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil doesnt have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP

21. Ensaios não destrutivos aplicados à madeira serrada e estruturas : técnicas potenciais para uso no Brasil
The wood has many different characteristics, resulting, in part, of the conditions in which the tree grows. The physical conditions of the wood are also influenced by its complex internal structure, resulting in an anisotropic behavior. Within this variability, its best use and application can be reached through non-destructive methods. The non-destructive m

22. Comparação de métodos não-destrutivos de cubagem de árvores em pé visando à determinação da biomassa / Comparison of non-destructive methods of wood volume determination of standing trees for biomass determination
As florestas são vistas como excelentes acumuladoras de biomassa e carbono da atmosfera, contribuindo para a redução do efeito estufa. Para ter conhecimento da biomassa acumulada nas árvores é necessário realizar determinadas técnicas para levantar o volume de madeira dos povoamentos. Desta forma, objetiva-se neste trabalho estudar a qualidade das med

23. Utilização de métodos não destrutivos e semi destrutivos na avaliação de pontes de concreto. / Use of non-destructive methods and semi-destructive evaluation of concrete bridges.
As estruturas de concreto, especialmente as pontes de concreto, estão sujeitas a um conjunto de ações que leva ao seu envelhecimento devido aos processos de deterioração, muitas vezes deixando de responder às exigências para as quais foram projetadas. Tal situação, em muitos casos, é agravada pela falta de conhecimento dos processos e mecanismos de
