We have previously shown that continuous exposure of the slime mold Physarum polycephalum to extremely low frequency (ELF) electromagnetic fields (EMF) simulating those generated by the Navy's ELF communication system (then Project Sanguine) could depress the rate of respiration, and lengthen the mitotic cell cycle. In a series of experiments beginning in 1981 and ending in 1987, we sought to determine whether exposing Physarum to the field environment around the Wisconsin Transmitting Facility (WTF) could induce an altered physiological state. A laboratory component was also included to help verify methodology and to supplement studies performed at the WTF. Initially, the experimental effort was directed to devising methods to maintain axenic Physarum cultures under ambient environmental conditions. This involved using growth chambers that admit the electric field or current density from the surrounding environment; the cultures were returned to the laboratory for analysis. The successful methods placed the organism on an agar bed inside double containment and introduced the samples to be assayed into shaken liquid culture medium upon arrival at the laboratory. Both WTF-generated electromagnetic fields and background strengths were measured with the help of IITRI at study locations near the antenna, at the west ground of the WTF antenna, as well as at control sites.

A pilot study was conducted to determine the nature and magnitude of seasonal variations in ELF Communications System ground terminal safety parameters land to identify the most appropriate methodology for ground terminal seasonal monitoring. This study was conducted at the Navy's ELF communications System's Wisconsin Transmitter Facility in northwestern Wisconsin over a seventeen month period from may 1987 to November 1988. Measurements of ground terminal step voltages and body currents at twelve test locations encompassing the principle terrain and soil types of the area were taken using several measurement methodologies. This report documents the pilot study and measurements, presents an analysis of the nature and magnitude of seasonal ground terminal variations, identifies the measurement methodology of choice for all-season monitoring, and makes recommendations for future monitoring of the ELF terminal grounds.

The Body Electric tells the fascinating story of our bioelectric selves. Robert O. Becker, a pioneer in the filed of regeneration and its relationship to electrical currents in living things, challenges the established mechanistic understanding of the body. He found clues to the healing process in the long-discarded theory that electricity is vital to life. But as exciting as Becker's discoveries are, pointing to the day when human limbs, spinal cords, and organs may be regenerated after they have been damaged, equally fascinating is the story of Becker's struggle to do such original work. The Body Electric explores new pathways in our understanding of evolution, acupuncture, psychic phenomena, and healing.

Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
