1. Metodologia para análise de trincas de hidrogênio em soldas através de ensaios destrutivos e emissão acústica / Methodology of Analysis of Hydrogen Cracking in Welding using Destructive Test and Acoustic Emission
The evolution of the processes of welding, registered in recent years in everybody, has occurred had to this process of manufacture to be related with the majority of the industrial applications, either in the construction as in the recovery of components. To this used procedures to evaluate the cracking sensibility in metallic structures comes being constan

2. Energía calorífica necesaria, durante la soldadura en servicio de tuberías para el transporte de petróleo
The thermal behavior during in service repair welding of oil transportation pipes was studied by finite element analysis in the present paper. Regression equations that relate peak temperature at the inner surface of the pipe and cooling time between 800 and 500ºC in the heat affected zone to the welding heat input, preheat temperature, and convection heat

3. Influencia da secagem em camada estacionaria delgada do milho (Zea mays) na qualidade do grão e viscosidade do amido extraido
Grain quality according to end use is a fundamental aspect. The objective of this work was the evaluation of com quality for wet milling, after drying in a fixed layer at different temperatures and initial moisture contents, through evaluation of non denaturated protein (turbidity test), stress cracking, degree of stress cracking (colorimetric test) and visc
