Spatial Variability and Distribution of the Metals in Surface Runoff in a Nonferrous Metal Mine by Bozhi Ren, Yangbo Chen, Guocheng Zhu, Zhenghua Wang, Xie Zheng

“…The results showed that the maximum concentrations of those five kinds of the metals (Sb, Zn, Cu, Pb, and Cd) in the surface runoff of the antimony mining area were lower than the standard value except the concentration of metal Ni. Their concentrations were 497.1, 2.0, 1.8, 22.2, and 22.1 times larger than the standard value, respectively. …”

Research on the bearing characteristics and parameter optimization design of variable-section anchor rods by Changxing Zhu, Shengran Zhang, Duo Li, Xu Liu, Jiaqi Guo, Huazhe Jiao

“…The results show that the appearance of hollow section leads to the increase of anchoring agent and surrounding rock interfacial shear stress and the decrease of elastic bearing capacity, and the variation range increases with the increase of hollow section size; When the dimension parameter of the hollow section reaches the critical value, the failure mode of the bolt will change from the slippage of the interface between anchoring agent and surrounding rock to the fracture of the rod at the position of variable section. …”

Age differences in the variability and distribution of sleep spindle and rapid eye movement densities. by Kevin R Peters, Laura B Ray, Stuart Fogel, Valerie Smith, Carlyle T Smith

“…Although age differences were observed in the degree of absolute variability (older adults had significantly larger variances than young adults for sleep efficiency and time spent awake after sleep onset), a similar pattern was also observed within the two age groups: the four sleep measures with the lowest degrees of relative variability were the same and included time spent in REM and Stage 2 sleep, total sleep time, and sleep efficiency. …”
