An Economic Consideration Guideline for the Selection of Corrosion - Control Strategies

ABSTRACT Corrosion has an enormous economic impact on our industries. Hence, it is very important for engineers to apply the appropriate corrosion prevention techniques to protect the metallic process equipment from corrosion.  Usually, engineers spend their effort seeking for the corrosion control strategies. In fact, the effective corrosion prevention projects should be technically and economically evaluated.  Engineers can assess the corrosion prevention strategies in terms of technical validity. Nevertheless, the economic consideration of the anti-corrosion strategies seems to be one of their problems. The purpose of this article is to present the economic techniques which can be employed as a quick guide to make decision of their corrosion prevention projects. The other purpose is to review the corrosion mitigation methods and the economic considerations of the financial investment in the corrosion prevention strategies.  The application of these techniques is also illustrated in a selected practical example.

The roles of perceived effectiveness and problem awareness in the acceptability of road pricing in Bangkok

This study investigated the effect of perceived effectiveness and problem awareness on social and individual scales on the acceptability of an assumed road pricing (RP) scenario in Bangkok. The results indicate that perceived effectiveness and problem awareness on the individual scale are determinants of RP acceptability, and that car users oppose the applicationof RP since they are not convinced of its effectiveness. The study suggests that when implementing RP, it is important to educate the general public, and especially car users, about the effectiveness of RP schemes in reducing the impact of traffic problems on the individual
