    Sammanfattning : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. LÄS MER

    Sammanfattning : This study is about voluntary productive activities in digital networks and on digital platforms that often are described as pleasur­able. The aim of the study is to relate the peer producers’ perceptions of their activities on a micro level in terms of play, game, work and labour, to their views on Wikipedia’s relation to capitalism on a macro level, to compare the identified ideological formations on both levels and how they relate to each other, and finally compare the identi­fied ideological formations with contemporary Marxist theory on cognitive capitalism.
