1. Cooperation and conflict over the struggle to reproduce in harsh environments : An experimental field study on ostriches
Sammanfattning : People are used to hearing that evolution is about the survival of the fittest. Theyimagine a world full of bullies that ruthlessly fight their way to the top in the struggle for life, leaving the weak behind. But this doesn’t need be the case. LÄS MER

3. Soil-living archaea: Influence of pH, carbon and nitrogen on their abundance and activity
Sammanfattning : During the last decade it has been discovered that around 2% of the soil-living prokaryotes belong to the domain Archaea. In many soils the most abundant archaeal group is the ammonia-oxidizing archaea (AOA) that, in addition to ammonia-oxidizing bacteria (AOB), preform the first and rate-limiting step in the nitrification process.

5. Evaluations of Non-metallic Inclusionsin Ca-treated Steels and Their Effect on the Machinability
Sammanfattning : In recent decades, a considerable development of steel with respect to the performance of steel has taken place, which also has resulted in large challenges to process these steel grades. Therefore, it is essential to make suitable modifications of non-metallic inclusions (NMI) in the steelmaking process and to have a good control of its characteristics to meet the target mechanical properties and to obtain a good machinability.
