The invention concerns a steel material which consists of a steel having the following chemical composition in weigh-%: 1. The present invention also relates to pharmaceutical compositions comprising such compounds and therapeutic uses thereof. Among other things, embodiments pertain to: a removable installation flange in the form of a two-part clamping flange or in the form of a one-piece rotary flange that is screwed on the fill opening similar to a bayonet catch. Lenses and corresponding image sensors are calibrated to have calibrated and associated settings for recording multiple images that are substantially registered images. The locking system resists loading conditions generated when the crop mat engages the element, prevents radially outward movement of the threshing andor separating element relative to the mounting lug, and reduces the stress on the mounting hardware during harvesting operations. A first conductive layer including a first metal is formed on the gate insulation layer, and a second conductive layer including a second metal different from the first metal is formed on the first conductive layer formed over the second channel.
