Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In the other hand, laboratory circumstances force many considered effective factors to be skipped in the scour phenomenon. In this situation, the...

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.

The designed service life of Hong Kong-Zhuhai-Macao Bridge is 120 years. Concrete quality control for the submerged tunnel of the project is an important work to assure the designed service life. This article is to present an advanced concrete performance prediction method based on water–binder ratio (w/b) monitoring, which is used to serve for concrete quality control. During experiments in th...

AIMS The aims of this thesis were to analyze reduced number of implants supporting full arch fixed mandibular prostheses and fixed partial dentures (FPDs), non-submerged healing and early loading in the edentulous mandible. A further aim was to evaluate fit of Computer Numerical Controlled (CNC) milled I-Bridge frameworks. MATERIAL & METHODS Paper I. One hundred and nineteen patients rehabili...

The Trans Bay Cable (TBC) is a ±200-kilovolt (kV), 400 MW 85-km long High Voltage Direct Current (DC) buried transmission line linking Pittsburg, CA with San Francisco, CA (SF) beneath the San Francisco Estuary. The TBC runs parallel to the migratory route of various marine species, including green sturgeon, Chinook salmon, and steelhead trout. In July and August 2014, an extensive series of ma...

Bridge pier scour is a complex process, which influenced by many parameters, including the presence of ice cover around piers. To better understand influence on bridge scour, an artificial cover, equipped with either smooth or rough surface, was constructed and tested experimentally. The positioned surface water submerged to specified depths in order replicate floating fixed (pressurized) condi...

The transverse vibrations of a two-span beam bridge, the shore supports which interact with surrounding soil during seismic action, are considered. condition is accepted that deformations structures do not go beyond limits elasticity and linear in nature. bridge assumed to be submerged ground interacting rigid body under action non-stationary dynamic influences. case considered when left, middl...
