Using a tight-binding model of charge transport in systems with static and dynamic disorder, we present a theoretical study of the positive charge transfer in molecular assemblies that involve a hole donor and an acceptor connected by fluorene and phenyl bridges. Two parameters that determine the rate of charge transfer within the proposed model are the charge transfer integral between neighbor...

The construction of integral bridges is one the most effective methods to reduce bridges’ and in-service costs. However, there are associated geotechnical problems with their abutments backfill due integrated abutments. main goal this study evaluate quantify benefits geogrid reinforcement for reducing backfill’s problems. For purpose, using small-scale physical modeling, reinforcing an abutment...

This study is to evaluate the behavior of integral and segmental specimens through static and cyclic tests. Integral specimens were made with the same size to be compared with segmental specimens that were made by connected precast members. To evaluate its bending performance and serviceability, 1 integral and 3 segmental specimens were tested under static load. And 1 integral and 2 segmental s...
