This paper presents a method for evaluating the reliability of an in-service highway bridge that considers the resistance capacity loss due to various corrosive environments. To demonstrate the application of the suggested method, a pre-stressed concrete-I (PSC-I) type girder was selected as a sample bridge. An analytical procedure was developed to quantitatively evaluate the performance degrad...

PURPOSE Bridge anticoagulation therapy is mostly utilized in patients with mechanical heart valves (MHV) receiving warfarin therapy during invasive dental procedures because of the risk of excessive bleeding related to highly vascular supporting dental structures. Bridge therapy using low molecular weight heparin may be an attractive option for invasive dental procedures; however, its safety an...

a new design for replacing a missing anterior tooth is described. in this article, a lingually fixed partial denture, its advantages, disadvantages, indication and contraindications have been explained. the ability of this design to replace a single missing central or lateral incisor is discussed.

To bridge the gap that exists in key equipment of new subsea production control system, all-electric gate valve actuator, and exploit oil gas resources with high reliability safety while saving energy, this paper proposes a novel concept prototype an actuator which has functions redundant drive, failsafe closing, auxiliary override, position indication, low-power holding. It satisfied electrica...

In proof-loading of concrete slab bridges, advanced monitoring methods are required for identification stop criteria. this study, Two-Dimensional Digital Image Correlation (2D DIC) is investigated as one the governing measurement crack detection and evaluation. The investigations deemed to provide valuable information about DIC capabilities under different environmental conditions evaluate in r...

The article shows the effect of torsional rigidity of beam elements onto spatial work of bridges, floorings and other plate-ribbed systems It is shown that, in determining the torsional rigidity using existing methods it is necessary to have spatial spiral cracks, but torsional rigidity when normal cracks is not researched. A method is described for determining the torsional rigidity of reinfor...
