BACKGROUND Scuba diving is one of the fastest growing sports in the world. The objective of this study was to evaluate the effect of pressure variations to which divers are exposed on the pull out strength of glass fiber post luted with different cements. MATERIALS AND METHODS In this in vitro study, 120 extracted, single-rooted lower premolars were endodontically treated. They were randomly ...

Innovations in the construction industry have led to a change technological structure, use of end-to-end technologies, innovative materials, information management and need for new technical, managerial solutions. The research problem is optimal placement glass-fiber reinforced plastic bars concrete structures. It took several steps solve problem: 1) development an algorithm solving design TEKL...

Glass fiber reinforced plastic (GFRP) composites have been applied to the manufacture of missile shields and unmanned aerial vehicle (UAV) shells. It is great significance explore ablation characteristics different lasers for these composites. Currently, most existing studies on are conducted under a single laser output mode, such as continuous wave (CW) or pulsed laser. However, combined not c...
