Most of the cases of dental implant surgery, especially the bone defect extensively, are essential for alveolar ridge augmentation. As known as cell therapy exerts valuable effects on bone regeneration, numerous reports using various cells from body to regenerate bone have been published, including clinical reports. Mesenchymal cells that have osteogenic activity and have potential to be harves...

The aim of this study is experimental assay of sensitivity and stability of a bimetallic silver/gold SPR sensor chip. This chip utilizes the sensitivity of the silver and the stability of the gold. Moreover, the Silver layer (instead of usual Cr or Ti layer) was used as an adhesive intermediate layer between the Gold layer and the glass substrate. The optimization of the Gold/Silver thickness u...

We developed a repeated sampling bone chamber (RSBC) and tested its suitability for studying various aspects of the bone allograft incorporation process under reproducible nonload-bearing experimental conditions in a large vertebrate. Our chamber is made of commercially pure titanium and is designed to allow bone or tissue ingrowth into a removable hollow inner core. Three chambers per animal w...

the built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. the built up layer (bul) is formed in second deformation zone near the tool-chip interface in the back of the chip. this parameter influences the tool life and machined surface quality. this bul should not be confused with the built up edge (bue). the deformation of the bul in...

nowadays network-on-chips is used instead of system-on-chips for better performance. this paper presents a new algorithm to find a shorter path, and shows that genetic algorithm is a potential technique for solving routing problem for mesh topology in on-chip-network.

Compound fractures and gunshot wounds of bone are common injuries of war. Compound fractures are becoming common injuries of civilian life with the increasing number of traffic and industrial accidents. In spite of careful primary excision, the use of antibiotics and the early immobilisation of the affected limb, a bone infection may become established because of contamination of the wound, los...

The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

as technology scales deep into the nanometer regime, on-chip communication becomes more susceptible to transient noise sources, such as crosstalk, external radiation, and spurious voltage spikes. the network on chip s modularity and reusability has brought about the use of error control methods to address transient errors in network on chip links.in this work, we design a fault tolerance router...

most of the materials used in the industry of aero-engine components generally consist of titaniumalloys. advanced materials, because of their excellent combination of high specific strength, lightweight and general corrosion resistance. in fact, chemical wear resistance of aero-engine alloyprovides a serious challenge for cutting tool material during the machining process. the reductionin cutt...
