1. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects
Sammanfattning : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.

3. Vitamin D, muscle strength, prolonged labour, Caesarean sections and lifestyle : Clinical and intervention studies in pregnant Somali and Swedish women and new mothers
Sammanfattning : Long-term severe vitamin D deficiency may cause osteomalacia with muscle weakness, pain, soft bones, cramps and eventually death. In a pilot study, I found many Somali women to be vitamin D deficient and very weak. LÄS MER
Sammanfattning : Anticipating future demands in skills and workforce development has been a longstanding practice and challenge for governments and policy-makers. While such developments are examined closely at the national and regional levels, an even more pressing issue is to advance our understanding of how people who take on jobs in new and emerging fields embark on and persist in their occupational pathways.
