Ambient Excitation

Many footbridges may suffer from the intensive vibration induced by human activities. To be a direct and effective approach, field measurement is widely utilized to assess the vibration serviceability of footbridge. The field measurement and modal identification of a cable-stayed footbridge is conducted in this study. The dynamic responses of the example footbridge subjected to ambient excitations are collected through field measurement and utilized to identify the structural dynamic properties by using two approaches. The made observation indicate that the peak acceleration responses at different testing points are different to great extent but the spectrum properties of all the points are quite similar. The fundamental frequency for the vertical vibration of the concerned footbridge is close to the lower frequency of the pedestrian loading and a relatively large vibration and discomfort of pedestrians can be observed

Urinary Glycoprotein

Much work has been reported on the chemical, physical and morphological properties of urinary Tamm-Horsfall glycoprotein (THG). Although it was once reported that cystic fibrotic (CF) individuals had a defective THG, more recent data indicate that THG and CF-THG are similar if not identical.No studies on the conformational aspects have been reported on this glycoprotein using circular dichroism (CD). We examined the secondary structure of THG and derivatives under various conditions and have correlated these results with quaternary structure using electron microscopy.THG was prepared from normal adult males and CF-THG from a 16-year old CF female by the method of Tamm and Horsfall.
