The influence of human resource management practices on occupational health and safety in the manufacturing industry.

This study provides an overview of the influence of applying two human resource management (HRM) practices on workers' occupational health and safety (OHS). These practices are selection and recruitment, and development and training. Furthermore, this study highlights the observed activities to define hazards, processes and OHS measures in the manufacturing industries.

The effect of resistance grooves on the fracture toughness of zirconia-based crowns from mono and cyclic loading.

Objective: Prosthetic molar crowns in service are subjected to chewing loads, which cause a shift or dislodgment. The objective of this study is to investigate whether the addition of resistance grooves to the proximal surfaces of the abutment teeth would enhance the fracture resistance of the zirconia crowns and to compare between the patterns of cracks development on the zirconia crowns after the application of mono loading versus cyclic loading forces.

Materials And Methods: Thirty-six all-ceramic zirconia cored crowns were prepared on the same abutment.
