One example of testing for water contamination in geographic areas to determine a risk of water contamination includes determining a risk of water contamination. The method includes forming a nanocrystal structure on a surface of the substrate which is a single crystal material, wherein the nanocrystal structure has an etched region and an unetched region. The acceleration to be applied from an actuator is made to act on the top end of the spindle through a holder plate in one accelerator, while the acceleration to be applied from an actuator is made to act on the base end of the spindle through the base in another accelerator. The mobile communication device thereby provides for automatic adjustment of various user interface characteristics based on the ambient conditions of the environment around the mobile communication device. The portion of the image is converted into the object. \u201d to the laminate by through-air technique.
