2. The use of Shearography technique to evaluate polymeric composite repairs - case study
ABSTRACT Pipelines are subject to a variety of defects such as wall thickness loss, grooves, dents and holes. To restore the pipe integrity, polymeric composite repairs can be used. The inspection of repaired pipes is of fundamental importance, not only to verify the initial integrity, but also to monitor their state over time. Shearography is a laser optica

3. Ocular Vestibular Evoked Myogenic Potentials
Introduction Diagnostic testing of the vestibular system is an essential component of treating patients with balance dysfunction. Until recently, testing methods primarily evaluated the integrity of the horizontal semicircular canal, which is only a portion of the vestibular system. Recent advances in technology have afforded clinicians the ability to as

6. Imunoexpressão de caderinas e integrinas no desenvolvimento do epitélio cutâneo humano / Immunoexpression of cadherins and integrins in the development of human skin epithelium
Introduction: Cadherins and integrins are important for maintenance of tissue integrity and in signal transduction during skin development. Distribution of these molecules in human skin development was investigated and associated with markers of differentiation, cytokeratins (CK) and involucrin (INV). Methods: Using immunohistochemistry expression of E- and

7. Behavior of surface integrity in cylindrical plunge grinding using different cooling systems
The superficial texture of the material can exert a decisive influence on the application and performance of the machined component. The conventional fluids used in grinding processes are environmental risk and can also be dangerous to the health. The disposal of these toxic fluids is expensive and the contamination in the proximities of the machines can pre

9. Effects of the machining in the surface integrity on the superaustenitic stainless steel / Efeitos da usinagem na integridade superficial de um aço inoxidavel superaustenitico
An investigation was made of the effects of the machining conditions employed in the turning operation on the surface integrity of ASTM A744 Grade CN3MN superaustenitic stainless steel. The main focus was the finishing operation, but studies were also carried out with a prior roughening operation. The main input variables in finishing were: tool rake angle,

12. Contribution to study effects of the turning operations in the surface integrity in a super duplex stainless steel. / Contribuição ao estudo da integridade superficial de um aço inoxidável super-duplex após usinagem.
The objective of this work was to study the effects of the turning operations in the surface integrity in a super duplex stainless steel (SDSS) ASTM A890-Gr6A. The focus of the work was the finishing operations but some tests in rough operations were carried out. A complete factorial planning was used for both, with 2 levels and 5 factors. The tests were con
