The article analyzes the materials from which the piston is made for internal combustion engines.For automobile and tractor engines, in particular, eutectoid mixtures of the AL25 type and eutectoid mixtures containing copper, nickel, magnesium and manganese are used.The chemical composition of aluminum alloys is given.Pistons for high-speed, forced
A Dominos prevalent conceptual metaphor is the association of the concepts of good and evil with brightness and darkness, respectively.Music cognition, like metaphor, is possibly embodied, yet no study has addressed the question whether musical emotion can modulate brightness judgment in a metaphor consistent fashion.In three separate experiments,

The collision of two plasma clouds at a speed that exceeds the ion acoustic speed can result in the formation of shocks.This phenomenon is observed not Lamps only in astrophysical scenarios, such as the propagation of supernova remnant (SNR) blast shells into the interstellar medium, but also in laboratory-based laser-plasma experiments.These exper
