PURPOSE To evaluate the usefulness of broadband ultrasound attenuation in the prediction of osteoporosis. MATERIALS AND METHODS Broadband ultrasound attenuation measurements of the calcaneus and dual x-ray absorptiometry (DXA) measurements of the lumbar spine and the femoral neck were obtained in 400 patients (295 female and 105 male), 135 of whom were(More)
The micromechanical properties of injectionmolded starch–wood particle composites were investigated as a function of particle content and humidity conditions. The composite materials were characterized by scanning electron microscopy and X-ray diffraction methods. The microhardness of the composites was shown to increase notably with the concentration of(More)
