This work is based on a study of necrosis in 150 femoral heads in adults who had no evidence of such causal factors as a fracture, dislocation, caisson disease, sickle-cell anaemia or Gaucher’s disease (Fig. 1). This condition has been recognised during the last ten years: but only eleven cases were seen before 1958, and no less than 139 during the next five years. Idiopathic necrosis was descr...

The paper studies the performance of Offshore Wind Turbines (OWTs) founded on Suction Bucket Jackets (SBJs) in clay under combined wind and seismic loading. A detailed 3D FE model soil–foundation–structure (SFS) system is developed used as a benchmark to assess efficiency an enhanced Winkler-based "Caisson-on-Winkler-Soil" (CWS) model, where soil replaced by nonlinear hysteretic elements. propo...
