An assembly for providing a saggar for use in high temperature applications, may include a rectangular base element and first and second sets of two rectangular wall elements, wherein the rectangular base element includes connectors on two opposite sides for connecting with the two rectangular wall elements of the first set of the rectangular wall elements at the two opposite sides. The anionic emulsifier is preferably a surfactant containing a phosphate group, such as octyldecyl phosphate. The file name of the common file is identified with a data source routine, which identifies the file name based on received first and second values. The DC-DC switching mode power converter thereby provides a regulated output voltage. The method includes determining priorities of provided services for target terminals of cellular phones and ratios of carrier signal to interference from multiple target terminals; and based on the determined priorities, transmitting packet data to each the target terminal of cellular phones. Polymerization of 1,1-disubstituted alkene compounds in an emulsion provides opportunities to better control the polymerization compared with bulk polymerization.
