The present invention relates to compounds of the Formula and wherein R, R21, R25-R33, m, n, X21-X23, and Q1 are defined herein. Other embodiments include unique apparatus, devices, systems, and methods relating to internal combustion engine including exhaust aftertreatment components, apparatus, and systems. Formed on the corresponding output signal of the model, which is proportional to the glow plug temperature, is a reference signal, which as a control value, lies on the electronic control controlling the heating flow of the glow plugs, which accordingly controls the heating of the glow plugs using the actual glow plug temperature determined from emulation. Additionally or alternatively, a hinge post may extend from the bracket from a point about the stanchion insertion space, preferably from the stop member, to allow hanging of a gate or other swinging structure from the hinge post.
