This invention pertains to the discovery that the human NELL-1 gene induces or upregulates bone mineralization. The jet ink composition comprises one or more organic solvents, a rosin resin, and a colorant, and optionally a co-binder resin, e. The method comprises the steps of assigning radio resources to a UE for enabling the UE to send uplink information to the base station. Optical spectrum dispersing means such as a grating or a prism receive the two relatively displaced beams, and disperse their spectral content onto a reading element such as a CCD. The bentonite-covered sand is added to collected sand to supplement it. A recess with a magnet arranged therein is provided in the ball pivot.
