Mechanoadaptation maintains bone mass and architecture; its failure underlies age-related decline in bone strength. It is unclear whether this is due to failure of osteocytes to sense strain, osteoblasts to form bone or insufficient mechanical stimulus. Mechanoadaptation can be restored to aged bone by surgical neurectomy, suggesting that changes i...
Weldolets are positioned on many mineral oil pipelines. The following questions had to be clarified: do the existing connecting pieces stand up to the varying stresses; which service life can be expected; and are there any additional measures or tests to be initiated for a safe operation of mineral oil pipelines. The well-proven instructions of rel...

The local failure strains of essential reactor vessel components are investigated. The size influence of the components is of special interest. Typical severe accident conditions including elevated temperatures and dynamic loads are considered. The main part of work consists of test families with specimens under uniaxial and biaxial static and dyna...
