A transmission gearing arrangements produces up to ten forward and one reverse speed ratios by selective engagement of various combinations of four shift elements. The method includes: partitioning speech data from a plurality of training speakers according to at least one speech related criteria ; grouping together the partitioned speech data from training speakers having a similar speech characteristic; and training an acoustic bubble model for each group using the speech data within the group. The base is provided thereon with a trough and a retaining strip. In accordance with the present invention, the simultaneous transmission of multiple antennas is supported in a wireless time-frequency transmission block of a multi-carrier wireless transmission system. The fixation element is insertable into the insertion element, and the insertion element is removable in a reverse screwing motion, leaving the fixation element positioned across the tear. These new compositions incorporate bioactive glass into cosmetics, personal care items, cleaning agents, biocidal agents, functional foods, and nutritional supplements.
