A shelf mounting support includes an annular flange portion having a side surface from which projects a cavity defining body portion. At least a portion the sheet of material contains a coating which includes collagen type I, fibrinogen, fibronectin, and von Willebrand factor. The side draw stream is particularly suitable for use in the production of caprolactam since the low levels of dimers of ACN and HMT do not greatly affect the catalyst life in the caprolactam production process. A chain assembly is attached between the canopy and basket assemblies for absorbing kinetic energy from an incoming disc thereby capturing the disc. A diffusion sheet for secondarily diffusing the luminous flux and a condensing sheet for condensing the second orientation component are formed by a single sheet to reduce the manufacturing process of the liquid crystal display device. The working gas produced is extracted and if appropriate after cleaning, is used as a carrier gas, at least in part for\u2014preferably pneumatic\u2014transport of an at least partially reduced metal-containing material in the form of fine particles.
