Background: Old laying hens are more prone to dietary calcium (Ca) and phosphorus (P) deficiencies as  they absorb Ca and P less efficiently than younger hens. OBJECTIVES: In a 2×2 factorial design, the influence of diets with two levels of available phosphorus (AP) and phytase enzyme on the laying performance, egg quality and tibia bone characteristics of laying hens at their late 2nd producti...

The present study applied FE methods to evaluate the biomechanical effects induced by implant configuration and bone quality within an augmented posterior maxilla. The aim of this study was to ascertain the optimal choice of implant on the basis of actual bone conditions. A couple of simplified maxillary segment models vary in bone quality (D2, D3 and D4 type) were constructed. Imlants were emb...

The aim of this dissertation was to assess the potential of cone beam computed tomography in bone quality assessment prior to implant placement. The emphasis was on radiographic bone density measurement as one of the most important criteria of bone quality. In chapter 1, the definition of bone quality and its relation with implant treatment success was explained. The application of different mo...

Bone-conducted speech is of low intelligibility, but its quality is not affected by noise. In this paper, we take into account such propertes of bone-conducted speech, and address a digital filter to reconstruct the quality of the bone-conducted speech signal obtained from a speaker. The reconstruction filter design method is derived based on a model assumption of pronunciation. Experimental re...
