Abstract In Simply supported bridge, superstructure and substructure are separated by the expansion joint bearing. Integral bridge (IB), deck is casted monolithically with abutment wall. bridges have increased redundancy, which improves its seismic performance. Bridge fails may fail due to failure of bearing, non‐availability seating width does not occur in IB. The single pile analysis performe...

In this paper, the mechanical behaviors of bridges with unseating prevention devices in the superstructure were investigated. These devices can prevent bridge from unseating and divert most of the seismic forces from transferring to the bridge columns. The models of the rubber bearing, restrainer, and shear key were proposed and implemented into the SAP 2000 to obtain the seismic response of th...

After analyzing the existing simplified methods of ship-bridge collision and comparing their pros and cons, a relatively safe simplified analysis process is put forward. The time-history curve of the ship collision force obtained from the ship-rigid wall collision simulation using the software LS-DYNA is put into the whole bridge dynamic model in SAP2000 and then dynamic response analysis of th...

Inhibition of gene expression by antisense oligonucleotides is limited by their low ability to enter cells. Knowing that sugar binding receptors, also called membrane lectins, efficiently internalize neoglycoproteins bearing the relevant sugar, 6-phosphomannose, for instance, oligonucleotides--substituted on their 5'-end with either a fluorescent probe or a radioactive label on the one hand, an...

2-(Thiophen-2-yl)thiazole was introduced as a π-bridge into diethylamino coumarin and novel coumarin sensitizers were synthesized with cyanoacrylic acid or rhodanine acetic acid as electron acceptor. Their light-harvesting capabilities and photovoltaic performance were investigated and compared with those of a similar sensitizer bearing a phenylthiophene bridge. Replacement of benzene in the π-...
