16. Arbetsmiljö, arbetsdelning, utslagning : en studie av städarnas arbetsförhållanden
Sammanfattning : Det dominerande inslaget i det här avhandlingsarbetet är det omfattande empiriska material, som utgör grunden för vår beskrivning och analys av städarbetet och städarnas arbetsförhållanden. I den beskrivning som vi gör strävar vi efter att redovisa en helhetsbild av arbetsmiljön. LÄS MER
17. Dynamics of some vibro-impacting systems with amplitude constraints
Sammanfattning : This thesis concerns the dynamics of some vibro-impacting systems with fixed or moving amplitude constraints. It is based on and includes five papers, marked A to E. Simple models of three different vibro-impacting systems with applications in the fields of impact hammers, granular flow and disk brakes in vehicles are analysed. LÄS MER
18. Newspaper reports : do they influence remembering of the main session material?
Sammanfattning : The present thesis was aimed at investigating whether pre-exposure to biased newspaper reports influences remembering of the main session material. In general, the results show that remembering of the main session material varies as a function of the pre-exposure to the biased newspaper reports. LÄS MER
19. An approach to long range production and development planning with application to the Kiruna Mine, Sweden
Sammanfattning : The mining industry is increasingly oriented towards large scale mining and the planning concept of "Just in Time", which means activities starting and ending as late as possible without jeopardising production. The buffers, consisting of production blocks and development ahead of production, are then minimi. LÄS MER
20. Studies of plasma-facing materials and macromolecules using scanning probe microscopy
Sammanfattning : The main topic of this thesis is experimental analysis of material surfaces using scanning probe microscopies. These microscopes are used for characterization through high-resolution topographical imaging, but also for controlled modification of surfaces and molecules. LÄS MER
