Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic response. As such, this paper proposes a new approach for balancing the ductility demand in irregular bridges by utilizing shape memory alloys (SM...

OBJECTIVE In all ceramic fixed partial dentures the connector area is a common fracture location. The survival time of three-unit fixed partial dentures may be improved by altering the connector design in regions of maximum tension. The purpose of this study was to determine the effect of buccolingual increase of the connector width on the stress distribution in posterior fixed partial dentures...

Abstract The jointless bridges includes integral bridges, semi-integral and extended deck bridges. adopts an abutment, its main girder, abutment pile under are fixed together to bear the force together. expansion joint device cancelled, integrity, durability driving comfort of bridge improved. In this paper, a simply supported girder in Fujian Province China is taken as research background, it ...

Ceramo-metal dental casting alloys are used for crowns and fixed partial dentures (bridges). Ni-Cr and Co-Cr are base ceramo-metal dental casting alloys and now account for the majority of the fixed metalceramic restorations used clinically. The corrosion of these alloys result in release of elemental components with potential adverse biological reactions. It is of great importance to investiga...

Introduction Prosthetic treatment modalities of edentulous patients will include ➀ Conventional complete dentures, ➁ Fixed prostheses with dental implants (Fixed bone anchored bridges), and ➂ Removable type of Implant retained overdentures (hereafter IOD). Especially among them above, since “The McGill Consensus Statement on Overdentures”1) (will be detailed later) was published in 2002, attent...

the maxillofacial region is one of the most injury-prone areas during road traffic accidents, personal violence, falls and sports. maxillofacial trauma can lead to breakage or avulsion of upper anterior teeth, which may cause significant aesthetic and functional problems. there are many treatment options available for rehabilitation including removable partial dentures, fixed partial dentures, ...

Neurofilaments in the axons of mammalian spinal cord neurons are extensively cross-linked; consequently, the filaments and their cross-bridges compose a three-dimensional lattice. We have used antibody decoration in situ combined with tissue preparation by the quick-freeze, deep-etch technique to locate three neurofilament polypeptides (195, 145, and 73 Kd) within this lattice. When antibodies ...

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
