This paper discusses the theoretical framework in designing and developing a multimedia app intended to increase knowledge and perceived awareness towards cyber-bullying among adolescents.Given that cyber-bullying has become more serious lately, steps should be taken to ensure that this threat is curtailed (Willard, 2007).Other than the conventiona
Risks of fire occurrence in underground mines are known for a long time.Evacuation and rescue plans allow to each underground mine to respond and establish control in case of emergency.The primary goal of this paper is to determine the optimal system for evacuation in case of fire in underground mines and through a process of computer simulation to
ObjectiveThe effects of different ultrasonic impact treatment time on cross section microstructure, surface residual stress, surface microhardness, and corrosion resistance of 42CrMo4 steel sample was investigated.ResultsThe results showed that after ultrasonic impact, a large amount of plastic deformation occurred on the surface of 42CrMo4 steel s
