2. Performance of the INCONEL 625 alloy weld overlay obtained by FCAW process
ABSTRACT Nickel-based weld overlays (cladding) are commonly used in oil & gas industry to extend the life of equipment under corrosive environment, as it improves the corrosion resistance without a significant increase in the manufacturing cost, when compared to a full nickel-based alloy equipment. Although there are extensive literature involving overlays a

3. O Desenvolvimento Rural no Estado do Rio de Janeiro a partir de Uma Análise Multidimensional
Resumo: A pequena importância econômica da agropecuária para o estado do Rio de Janeiro não implica na inexistência de áreas rurais, mas, sim, que as áreas rurais do estado estejam diante de uma realidade em que outras funções dos espaços rurais estejam presentes (lazer, turismo) e que essa ruralidade seja capaz de fornecer processos virtuosos de d

4. Leakage Resistance Envelopes of API 8 Round Casing Connections using FE Analysis
Abstract Leakage resistance of casing connections can be evaluated by extremely expensive testing procedures. Although testing is required for connection validation, significant amount of resources can be saved by complementing testing with Finite Element (FE) analysis. In this regard, a broadly accepted criterion to characterize leaks in FE simulation is st

5. Misfit and fracture load of implant-supported monolithic crowns in zirconia-reinforced lithium silicate
Abstract Zirconia-reinforced lithium silicate (ZLS) is a ceramic that promises to have better mechanical properties than other materials with the same indications as well as improved adaptation and fracture strength. Objective In this study, marginal and internal misfit and fracture load with and without thermal-mechanical aging (TMA) of monolithic ZLS and

6. Comportamiento a la corrosión atmosférica marina de aceros autopatinables con estructura ferrítico perlítica y ferrítico martensítica
ABSTRACTThe steel industry constantly faces the challenge of developing new and better steels for diverse needs, on of this necessities is the use of structural steels with higher corrosion resistance to marine atmospheres and improved mechanical properties than those that currently exist. Therefore, it is necessary to systematically research both the influe

7. Máscaras mecânicas de sombra por eletrocorrosão para dispositivos eletro-ópticos
Shadow masks are used in manufacturing processes for electro-optic devices to transfer patterns with different shapes and dimensions. For fabrication of organic based devices, shadow masks should be made of materials stable against organic solvents, high temperature, and robust, remaining unchanged after multiple cycles of use and fixation. Thus, stainless s

8. The use of cylindrical grinding to produce a martensitic structure on the surface of 4340 Steel
Grinding is one of the most widely used manufacturing processes and, in the last few decades, has developed considerably. An example of these developments is hardening by grinding, an operation that is being studied to provide an option to the conventional hardening processes. This study presents the use of a cylindrical grinding process to produce a martens

9. Aplication of unscented transformed (ut) for design filters microwave / Aplicação da transformada de incerteza (ut) para projeto de filtros de microondas
The manufacture of complex filters and their tests depend on electromagnetic simulation for validation and correct analysis. However, in the filter assembly, the fabrication process introduces new sources of uncertainty that are difficult to model with the electromagnetic simulator. The result may be significant differences between the simulated responses an

10. Estudo do desalinhamento das fibras nas propriedades mecânicas de compósitos estruturais de pás eólicas / Study of fiber misalignment effects on the mechanical properties of wind blades structural composites
This work presents the study of waviness influence on the mechanical properties of wind blades structural components fabricated by vacuum infusion. For this purpose, out-of-plane waviness, which is a common manufacturing defect, was induced on glass and carbon reinforced plastics (GRP and CRP) and compared with control laminates without waviness (wave-free c

12. Monitoramento da microbiota e dos parâmetros físico-químicos em vinhoto / Monitoring of microbiota and physicochemical parameters in vinasse
The agro-industrial activities are responsible for generating large amounts of liquid waste. In the production of cachaça, the production of vinasse is about 4 times higher than the production of the spirit. Usually, tanks for deposition of vinasse are constructed by the producers to receive the residue from the manufacturing process. The main aim of this w
