A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...

Today’s, the transportation facilities such as terminals, street, bridge, etc, represent the major investment in highway network. Every year tremendous resources should be invested to maintain these facilities. Among them, the Bridge Management System (B.M.S.) has been necessitated by large imbalance between extensive bridge repair and maintenance needs and limited available budget. So the main...

High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Solving tangle equations is deeply connected with studying enzyme action on DNA. The main goal of this paper to solve the system N(O+X1)=b1 and N(O+X2)=b2#b3, where X1 X2 are rational tangles, bi a 2-bridge link, for i=1,2,3, b2 b3 nontrivial. We under assumption Õ, double branched cover O, not hyperbolic, i.e. O π-hyperbolic. Besides, we also deal involving links only an algebraic tangle.

We report here an impedimetric genosensor for the quantification of microRNA-21 using [Fe(CN)6]3?/4? as redox probe to transduce hybridization event. The biosensing platform was built at a thiolated-gold electrode by covalent bond reduced graphene oxide (RGO) modified with chitosan (CHIT) and further attachment aminated DNA probe. GO used provide carboxylic groups CHIT and, once reduced, improv...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

Nucleosomes form the fundamental building blocks of chromatin. Subtle modifications of the constituent histone tails mediate chromatin stability and regulate gene expression. For this reason, it is important to understand structural dynamics of nucleosomes at atomic levels. We report a novel multiscale model of the fundamental chromatin unit, a nucleosome, using a simplified model for rapid dis...

scour around bridge piers is one of the most important fields of hydraulic research. local scour around bridge piers and abutment is one of the main reasons of bridge failures. in the field of scour at the bridges, researches are more focus on scour of piers in compare with abutment. while the available information on the bridge failures required cost, the major problems are related to abutment...
