Techniques are provided for decoding machine-readable optical codes that have an aesthetic component that is integrated into the codes themselves. In the semiconductor memory device of the present invention, decoding drivers are arranged in sense amplifier regions. An omega-3 fatty acid of docosahexanoic acids and eicosapentaenoic acids extracted from the above method. The preform has associated therewith at least one reflector disposed in the threaded andor neck region for deflecting radiation proportions piercing the neck region and for heating the neck region on an inside of the preform.
