Background: In periodontal regeneration, several alloplastic materials are being used with a goal to reconstruct new osseous tissue in the infrabony defect sites.The present study was undertaken to evaluate the efficacy of hydroxyapatite-bioactive glass (HA:BG) composite granules in the management of periodontal bony defects.Materials and Methods:
To control the current of a surface mounted permanent magnet synchronous machine fed by a two-level voltage source inverter, a large variety of control algorithms exists.Each of these controllers performs differently concerning dynamic performance and control- and voltage quality, but also concerning sensitivity to demagnetization faults.Therefore,

With the sixth large-scale railway speed-up, the quality of the axles is essential to the safety of the locomotive.According to the high-speed axle technical standard for the control of alloy ranchy doodle elements in axle steel, optimization experiments of 25CrMo steel composition were performed by vacuum inductive melting.In order to study the ha
This study uses biogas, an environmentally friendly renewable energy resource, to operate the prototype of a micro-gas turbine (MGT) system called the Proto X-3 Bioenergy Micro-gas Turbine, designed for green building application.The biogas is produced by an anaerobic digester.The aim of this research is to simulate slurry flow in an anaerobic dige
