30. Avaliação das propriedades de transporte de massa contendo adições minerais / Evaluation of the mass transport containing mineral admixtures
The durability of reinforced concrete structures is damaged by the degrading action of the penetration of substances in the form of gases, vapors and liquids through the pores and cracks. It is known that water both in its pure form or containing dissolved ions such as chloride, sulphate, carbon dioxide or oxygen ions, can compromise the durability of concre

31. FLOW OF EMULSIONS IN POROUS MEDIA: EXPERIMENTS AND CAPILLARY NETWORK MODEL / ESCOAMENTO DE EMULSÕES EM MEIOS POROSOS: EXPERIMENTOS E MODELO DE REDE DE CAPILARES
Objective: Transport of emulsions in porous media is relevant to several subsurface applications. Many enhanced oil recovery processes involve emulsion formation and their flow in some form. Modeling the flow of emulsion in porous media is extremely challenging. The available descriptions based on effective viscosity are not valid when the drop size is of th

32. Development of extruded profiles from high density polyethylene and wood flour composites / Desenvolvimento de perfis extrudados de compósitos de polietileno de alta densidade com farinha de madeira
Polymer profiles extrusion shows some peculiarity due to the flow behavior of these materials during the processing. On the other hand, the profile die design and tooling has been more a result of professionals expertise than an engineering project in essence. In the present work, it was aimed to combining concepts of computers aided engineering to rheologic

34. Influência da areia argilosa na recuperação de petróleo por injeção de vapor
Continuous steam injection is one of heavy oil thermal recovery methods used in the Brazilian Northeast because of high occurrence of heavy oil reservoir. In this process, the oil into the reservoir is heated while reduces, substantially, its viscosity and improves the production. This work analyzed how the shaly sand layers influenced in the recovery. The s

35. Time course of training-induced microcirculatory changes and of vegf expression in skeletal muscles of spontaneously hypertensive female rats
Exercise-induced vessel changes modulate arterial pressure (AP) in male spontaneously hypertensive rats (SHR). Vascular endothelial growth factor (VEGF) is important for angiogenesis of skeletal muscle. The present study evaluated the time course of VEGF and angiogenesis after short- and long-term exercise training of female SHR and Wistar Kyoto (WKY) rats,
