16. Den andra rollen : ett fältarbete bland skådespelare, regissörer och roller
Sammanfattning : This book is about the actors in The Sun and The Moon , two plays staged at Stockholm City Theatre. It is about role-play in the fictive story developed during rehearsals and in the social drama that kept unfolding in the production groups. My aim has been to describe the actors' work as a specific social process within a dual reality. LÄS MER
17. Mechanical behaviour of a roller bearing steel : Strength differential effect, low temperature creep and propagation of short cracks
Sammanfattning : Fatigue cracks in bearings either initiate from the surface or from an inclusion below the rolling contact surface. Then, short cracks start to propagate. Short crack grow at considerably faster rates than long cracks subjected to a nominally equivalent stress intensity factor range. LÄS MER
18. Barn och ungdomar med rörelsehinder : deras uppfattningar om roller, relationer och aktiviteter
Sammanfattning : The general aim of this thesis was to describe how children and adolescents with restricted mobility perceived their roles, relations and activities in relation to peers and adults in different settings. The thesis includes six sub-studies, which are based on interviews, observations and field notes with children and adolescents with restricted mobility aged from 6 to 19 years. LÄS MER
19. Finite Element Analysis of Case-Hardened Roller Bearings
Sammanfattning : This thesis deals with the material modelling of case-hardened bearing steel, with special reference to hardened roller bearing components. The result of a case-hardening process is a hardened component with substantially improved material properties within a restricted region beneath the heat-treated surface. LÄS MER
20. Elastohydrodynamic Lubrication of Cam and Roller Follower Applications : Fast and Reliable Predictions of Friction
Sammanfattning : Modelling and simulation in tribology, and more specifically of friction in lubricated contacts, has gained increasing attention over the past years. In a lubricated contact, the dissipation of energy is due to the relative motion of the mating surfaces and arise due to direct contact as well as shearing of the lubricant film. LÄS MER
