The permanent magnets based on the Nd-Fe-B system have been subject of a broad scientific research in the last decade and reached a competitive stable commercial position. However, it is recognized that these family of magnets still presents low thermal stability and poor corrosion resistance, which have been in some sense, acting as a barrier to many applications where the temperature or the environmental humidity is found to be even slightly higher than the optimal working condition. |

The paper examines three different evaluation tools applied to extensive and semi-intensive beef production systems in South America. System behaviour was tested for the impact of interventions on energy efficiency and methane output by using simulation models. Compensatory carbon sequestration area was calculated for 31 beef production enterprises with three levels of production intensity using a ?carbon footprint? type of accounting. Evaluation of water productivity was carried out by calculating ?virtual water contents? for three levels of production intensity typically found in South America. |
