   Sammanfattning : In this thesis, a simplified narrow-band approximation model is proposed to estimate fatigue damage of ship structures, and an efficient method for extreme response predictions is also developed using upcrossing spectrums of ship responses. The proposed fatigue model includes two main parameters, significant stress range hs and zero upcrossing frequency fz. LÄS MER

3. 2. Extensive tooth wear in adults : classification and prosthetic treatment

   Författare :Wedad Hammoudi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Tooth wear (TW) is an insidious and cumulative mul- tifactorial process that may comprise erosion, abrasion or attrition, and combinations thereof. These different processes are of chemical or physical origin and not microbiological. LÄS MER
