Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Steady improvements have been made through five systems for operating an artificial heart with a Stirling engine that will be heated by a radioisotope or by an electric heater which receives power from a transcutaneous transformer. A thermal storage reservoir assists in supplying peak power demands. The engine regenerator, a primary component, was substantially improved by changing from a porous to a hollow regenerator. Engine efficiency was doubled. The current engine, using a hot flexural support at the engine, a bellows-sealed lower support, a drive piston, and a flywheel for continuity of regenerator motion, has been quite successful. Potential reductions in size and isotope requirement are discussed. The computed dose rate for the system is also given. Development is continuing toward a reliable realistically sized artificial heart with reasonable power demands.
