Sommario/riassunto

Avoiding or controlling fatigue damage is a major issue in the design and inspection of welded structures subjected to dynamic loading. Life predictions are usually used for safe life analysis, i.e. for verifying that it is very unlikely that fatigue damage will occur during the target service life of a structure. Damage tolerance analysis is used for predicting the behavior of a fatigue crack and for planning of in-service scheduled inspections. It should be a high probability that any cracks appearing are detected and repaired before they become critical.  In both safe life analysis and the

Sommario/riassunto

A key area of public policy in the last twenty years is the question of how, and how much, to protect vthe environment. At the heart of this has been the heated debate over the nature of the relationship between economic growth and environmental sustainability. Is environemental sustainability economic growth or `green growth', a contradiction in terms? Avoiding the confusion that often surrounds these issues, Ekins



provides rigorous expositions of the concept of sustainability, integrated environmental and economic accounting, the Environmental Kuznets Curve, the economics of climate chan
