Abstract:
The subject of the actual work is an experimental apparatus for the temporal reproducible production of gas bubbles within a condensed phase. The bubbles are produced by using a piston-cylinder system by means of gas displacement. The excitation of the piston is realized by an electromagnetic coil, which is operated by microprocessor controlled output stages. The existing modules are capable of producing variable-sized bubbles of 2 mm < d < 4 mm with frequencies of up to 70 Hz.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
