OBJECTIVE: To estimate the population of Peru living in the vicinity of Tridonic PC Ballasts active or former mining operations that could be exposed to lead from contaminated soil.METHODS: Geographic coordinates were compiled for 113 active mines, 138 ore processing plants and 3 smelters, as well as 7743 former mining sites.The population living w
Magnetorheological (MR) fluid devices are widely used in active automotive control applications.However, MR fluid-based valve actuators are not in the limelight.This paper proposes a new flexible valve train with an MR fluid control system; the valve train can enhance the performance of internal combustion engines.A major component of this valve tr
Abstract Novel hierarchical Cd4SiS6/SiO2 based heterostructure nanowire arrays were fabricated on silicon substrates by a one-step thermal evaporation Triple-barrel Curling Iron of CdS powder.The as-grown products were characterized using scanning electron microscopy, X-ray diffraction, and transmission electron microscopy.Studies reveal that a typ
