Blast casting is a high-efficiency technique applied in surface mines for overburden removal and results in stripping cost savings.According to ballistic theory and center-of-mass frame basic Pouches movement principles, key factors influencing blast casting effect were analyzed, which include bench height and mining panel width, inclined angle of
Research has shown that face-to-face victimization is a risk factor for the online victimization of adolescents, but no prior study has examined and compared four forms of face-to-face victimization (physical victimization, verbal Cushion victimization, social manipulation, and attacks on property) as significant correlates of general online victim

Abstract Evolutionary biologists have long sought to understand what factors affect the repeatability of adaptive outcomes.To better understand the role of temperature in determining the repeatability of adaptive trajectories, we evolved populations of different genotypes of the ciliate Tetrahymena thermophila at low and high temperatures and follo
Nowadays, secret information is susceptible to numerous hacks while being shared Downstems through traditional correspondence channels.Unlike other methods of securing data, steganography offers the most comprehensive security.Several algorithms have been developed to determine the optimal embedding capacity of every pixel to enhance steganography
