Abstract Bridge foundation scour is one of the major problems for bridges in Nepal. Kathmandu Valley, which main economic hub and capital Nepal lies a seismically active zone. In this study, bridge spanning over Bagmati River Valley studied as reference to assess seismic response typical affected by scouring. Modal analysis revealed becomes more flexible when depth 2 m considered. A series push...

Homeland security requires thorough monitoring of the nation’s transportation infrastructure health. Discussed in this paper is research aimed at developing a smart wireless sensor network that is an efficient and practical health monitoring system and is also versatile for security monitoring strategies. At the core of such a system is an integrated network which collects data from a variety o...

The abutment(s) of a partial fixed dental prosthesis (PFDP) should have a minimal total occlusal convergence (TOC), also called a taper, in order to ensure adequate retention of a PFDP that will be made for the abutment(s), given the height of the abutment(s). This article reviews the concept of PFDP abutment TOC and presents an alternative definition of what TOC is, defining it as the extent t...

Past research has shown that as skewed bridges change temperature, additional lateral movement or forces will occur along with the elongation of bridge. Even though past documented this behavior, movements semi-integral bridge superstructure associated temperature effects on skewness have not been well predicted. In study, seasonal a 24-year-old caused by abutment investigated conducting series...

scour around hydraulic structures is an inevitable phenomenon . recognition of this phenomenon and dealing with it is an issue considering which will ensure the project success . local scour at piers has been reported as the most important factor in the destruction of the bridges . the use of submerged and non-submerged piles is one of the scour control methods . submerged piles have been rarel...

Deterioration and aging of bridges structures and damage caused by strong earthquakes might be conducive to collapse of the bridge, sometimes with catastrophic consequences. Therefore, investigation of structural condition of bridges is necessary for secure safe road operations. This paper presents a prototype of piezoelectric-cable sensor for vibration monitoring system that permits easy evalu...

provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations; but compromised abutment preparation may affect the retention of implant-retained crowns.the purpose of this study was to investigate the effect of abutment design and type of luting agent on the retentive strength of cement-retained implant restorations.two prefabricated abutments ...
