A system and method indexes and retrieves documents stored in a database. In particular, the invention relates to amphiphilic dendron-coils, micelles thereof and their use for drug delivery vehicles andor cell capture. The nose cone assembly also includes a flange positioned radially inward of the outer surface and axially adjacent to the base portion. Each set of camera parameters is used to alter the position of the pixel grid relative its original position so that a grid of samples can be generated at the new grid position. The secured digital container when locked to a user or user’s device may not open or permit access to the contents if the digital container is transferred to another user’s device. The device has an attached mounting surface, rotatable through 360\xb0, or a specified range, projecting one or more guiding fins, substantially perpendicular to the rotatable mounting surface.
