25. The influence of die geometry on stress distribution by experimental and FEM simulation on electrolytic copper wiredrawing
The study of die geometry is vital in determining the surface and mechanical properties of drawn wires, and consequently, their application. In this work, annealed electrolytic copper wire (ETP), with 0.5 mm original diameter was reduced by 19% in dies with 2β = 10º and 18º and Hc = 35 and 50%. The best experimental results were then studied by the Finite

27. Performance evaluation of carbide tools on automotive valve guides reaming / Avaliação do desempenho de ferramentas de metal duro no alargamento de guias de válvulas automotivas
Reaming is a machining process with relatively low cost and suitable when high quality holes are required. The purpose of this work is to evaluate the quality of the holes made in automotive valve guides, fabricated with sintered steel. This study was based on parameters of surface roughness, roundness and cylindricity deviations, obtained with uncoated carb

31. Parametric optimization of wire electrical discharge machining (WEDM) process using taguchi method
Wire electrical discharge machining (WEDM) is a specialized thermal machining process capable of accurately machining parts of hard materials with complex shapes. Parts having sharp edges that pose difficulties to be machined by the main stream machining processes can be easily machined by WEDM process. Technology of the WEDM process is based on the conventi

32. Oral Candida flora from Brazilian human immunodeficiency virus-infected patients in the highly active antiretroviral therapy era
One of the main opportunistic fungal infections amongst immunocompromised individuals is oral candidosis, which has been found in up to 90% of human immunodeficiency virus (HIV)-infected patients. This study employed yeasts isolated from the saliva and oral cavities of 114 HIV-infected patients living in Campinas, São Paulo. Of the isolates, 57.8% were iden

33. Estudo da instantaneização de misturas contendo cacau em po por aglomeração com jato de vapor
The agg1omeration process of dry mixtures containing cocoa powder was considered in order to evaluate the instant properties of the product. A pilot-plant steam jet agg1omerator was developed, composed by a stainless steal tower (diameter: 0.30m; height: 2.15m), a vibrating feeder for the powder supply (up to 65 kg/h), a steam generator, a device to promote

35. The application of Process Management for reliability enhancement of the Taguchi method
The concept of Process Management has been used by managers and consultants that search for the improvement of both operational or managerial industrial processes. Its strength is in focusing on the external client and on the optimization of the internal process in order to fulfill their needs. By the time the needs of internal clients are being sought, a se
