The present invention relates to a novel Neutrokine-alpha, and a splice variant thereof designated Neutrokine-alphaSV, polynucleotides and polypeptides which are members of the TNF family. The hand portion includes an exterior surface for handling an object and an interior surface for abutting the hand of the wearer of the glove. One of the waveguide structures is substantially straight and connects an input port to an output port. The arrangement member has two or more line members of which the core axes are substantially aligned. Latest data on the remaining quantity of each ink is alternately written into these two memory divisions.
