Sammanfattning : WC/Co cemented carbide is a composite material for highly demanding wear applications. The unique combination of hardness (from the WC-phase) and toughness (from the binder Co) gives a material especially suitable for rock drilling. LÄS MER
5. Origin, evolution and biodiversity of the Neotropical herpetofauna: patterns and processes of the world’s richest and most threatened biota
Sammanfattning : The biological diversity of tropical America (the Neotropics) is astonishing. However, even among terrestrial vertebrates, most biogeographical patterns are not fully described nor understood, especially for many Neotropical reptiles and amphibians (the herpetofauna). LÄS MER
