the knee bracing steel frame (kbf) is a new type of energy dissipating frame which enjoys exceptional ductility and lateral stiffness. rather than the beam-column joint, one end of the diagonal brace in kbf is attached to the knee element. indeed, the knee element as a hysteretic damper is designed and detailed to behave like a structural fuse by sustaining controlled inelastic deformations as ...

A major goal in multistep carcinogenesis research is the integration of recent findings obtained by sophisticated molecular-genetic and cytogenetic analysis of cancer into the more descriptive concepts of experimental pathology. It is proposed that the creation of a promotable cell in carcinogenic initiation requires a response modification to extracellular or intercellular signals. Different t...

A multifactorial approach to the aetiology of oesophageal cancer was made on the basis of a case-control study in Saitama prefecture, Japan. The joint risks of two factors were calculated directly from joint distributions, following a dichotomous exposure model. Three models of factor combinations were taken into account: two risk enhancing factors, two risk reducing factors, and risk enhancing...
