A connect-release zipping system basically comprising four zipper tracks, four zipper sliders on the zipper tracks, and a central connector to which the zipper sliders are affixed. A top sleeve portion of the package body can be configured to include a recloseable fastener, a dispensing spout, or an upper package seal. The method embodiment can also include projecting the changes in position of each of the first tooth and the second tooth onto a reference line and calculating a change in position on the reference line for the first tooth and the second tooth. Additionally, the central data processing system may issue instructions concerning mobile assetvehicle operation, with those instructions communicated over the wireless interface to the mobile portal. In the case where ABO3 is, for example, BaTiO3, the crystal grains include BaTiO3 crystal grains composed of the main component and, as secondary phases, Mg\u2014Ni\u2014Ti-containing crystalline grains composed of a crystalline oxide containing at least Mg, Ni, and Ti and Ba\u2014Si-containing crystalline grains composed of a crystalline oxide containing at least Ba and Si.
