The influence of external stresses on the transformation behaviour has been studied for a polycrystalline Fe-3 IMn-SSi alloy exhibiting the y-+& martensitic transformation. Samples have been loaded at temperatures above the M, temperature, cooled with a constant external load to a temperature below the M, temperature and subsequently heated without load to a temperature above the A, temperature...

H3N2 human influenza A virus causes epidemics of influenza mainly in the winter season in temperate regions. Since the antigenicity of this virus evolves rapidly, several attempts have been made to predict the major amino acid sequence of hemagglutinin 1 (HA1) in the target season of vaccination. However, the usefulness of predicted sequence was unclear because its relationship to the antigenic...

The cervical facet joints are a source of pain in some chronic whiplash patients. Clinical data show that a head-turned posture increases the severity and duration of whiplash-related symptoms. The objective of this study was to quantify strains in the facet capsule during whiplash-like loading with an axial intervertebral pre-torque simulating an initial head-turned posture. These strains were...

The influence of pre-strain on the tensile and fatigue properties a dual phase DP600 steel was studied. material pre-strained by uni-axial tension in rolling transverse direction. Thereafter, specimens were cut from deformed plates parallel or orthogonal to It found that increases yield strength. Results suggested strain path change primarily affects elastic-plastic transition during early stag...
