A content distribution method distributes a package containing a content from a content distribution apparatus to a terminal of a content distribution destination and causes the terminal to expand and display the content contained in the distributed package by using expansion software provided in the terminal. In an embodiment, a method matches object images from a set of object images to a root object image. Tilted gratings for diffracting an incident optical beam and emitting the beams as diffracted optical beams to the outside of the waveguide are formed within the optical waveguide. In addition, each of the plurality of assembly stations includes a container manipulating assembly, a spout grasping and positioning member and a joining assembly. At least one basis function is selected to distinguish a material of interest from other materials likely contained with the item, allowing one of the basis function images to be analyzed to obtain information about a specific material of interest. The invention thus relates to the plants, seeds and tissue cultures of the variety CH440394, and to methods for producing a corn plant produced by crossing a corn plant of variety CH440394 with itself or with another corn plant, such as a plant of another variety.
