A drive steel member for driving engagement with a rotary drilling machine, including a chuck adapter having main body and chuck seating means and being constructed and arranged in fixed, sealed relation on one end of the drive steel member. The invention further relates to methods for lysing certain bacteria using lysin, which are useful for example in the treatment of an oral cavity bacterial infection. Additionally, the result of a positional text condition may itself be provided in the form of a bitmap to accelerate further bitmap-based condition processing. The wireless repeater forwards information received from a wireless macro network base station to the wireless in-building base station, and forwards information received from the wireless in-building base station to the wireless macro network base station. The substrate unit has a positive guiding substrate electrically connected to the positive pins of the capacitor units and a negative guiding substrate electrically connected to the negative electrodes of the capacitor units.
