Methods and systems for generating location-aware group recommendations are discussed. In one arrangement, the analyzer contains the emission gas sample under a vacuum or negative pressure while detecting fluorescence of the elemental mercury within the emission gas sample. Even more particularly, the present invention relates to snack pieces having an improved dip holding containment region with a grip region that avoids messy finger contact with the dip that is readily communicated and discernible to the user by the shape of the snack piece and a method to make such a snack piece. The converted data files may then be stored in a memory. The tool may be pressed against a surface, first engaging the materials with a low coefficient of friction. The size of the buffer that stores ISO requests controls the amount of memory bandwidth that is allocated to the ISO requests and the amount of memory bandwidth available for NISO requests.
