A method for storing a water-soluble undissolved silica-based material, optionally with an incorporated functional agent. The facility includes an array of rotating media wheels that create an optimum ordered mixing of algae for sustained growth. A currently selected index is used to index data bits to the data array and tag bits to the primary tag array. The adjusted temperature value is tested for alarm conditions and displayed for use by a caretaker. The guided wave ultrasonic energy is maximized with a shaped tone burst pulse at the specified frequency rather than an electrical spike commonly used to excite transducers in standard ultrasonic search units. The device comprises means implementing a semi-empirical method for determining the critical loads generated by some buffeting on the structure of the airplane.
