The present invention pertains to a system for electronic brachytherapy wherein a layer of target material can produce reflection and transmission X-rays when struck by electrons from a cathode. The audio amplification apparatus includes a forward transfer path connectable to an output transducer, the forward transfer path including a frequency transposing element. A plurality of anemometers, each of which is connected to a particular variable-positioned device, measure airflow across the variable-positioned devices. The bandage is made from an elastomer such as polyeurathane with the addition of silicon and vegetable oil. 0% by weight, a stabilized nitrocellulose or a nitrocellulose-based propellant powder from 0.
