Non-thermal efects of alternating electrical fields on biological structures ( Book )
3 editions published between 1964 and 1970 in English and held by 3 WorldCat member libraries worldwide
Four possible non-thermal effects of alternating electrical fields were experimentally and theoretically studied. These four effects were assessed for their possible biological significance. These effects, all the result of mechanical forces on particles dispersed in a fluid, are (1) pearl-chain formation, (2) orientation of nonspherical particles, (3) forces in inhomogeneous electrical fields, and (4) alternating electrophoresis. Summaries of research on each of these effects are presented

SCATTERING AND ABSORPTION OF MICROWAVES BY DISSIPATIVE DIELECTRIC OBJECTS: THE BIOLOGICAL SIGNIFICANCE AND HAZARDS TO MANKIND ( )
1 edition published in 1963 in English and held by 2 WorldCat member libraries worldwide
The relative absorption cross section of mankind exposed to nonionizing microwave radiation was determined using doll and sphere phantoms whose electrical properties simulated those of a human being. The investigation proceeded in three stages of increasing difficulty: (1) theoretical and experimental study of homogeneous phantoms, having the electrical properties of muscle tissue; (2) theoretical studies of two-layer phantoms, having the electrical properties of muscle tissue and subcutaneous fat; and (3) ex trapolation to three-layer phantoms, having the electrical properties of muscle tissue, subcu taneous fat, and skin. The investigation at each stage resulted in certain generalizations which could be used as a guide to the investigations at the succeeding stage. In this way both the theoretical and experimental work necessary was simplified. The final stage involved a synthesis of all the previous work so that the relative absorption cross section of mankind could be predicted with confidence for the total frequency range from 400 to 10000 Mc/s
NON-THERMAL EFFECTS OF ALTERNATING ELECTRICAL FIELDS ON BIOLOGICAL STRUCTURES ( Book )
2 editions published between 1962 and 1967 in English and held by 2 WorldCat member libraries worldwide
A theory of pearl-chain formation, describing, from fundamental physical principles, the process whereby small particles align under the influence of an alternating electrical field, was developed and reported in 1961. It treated two cases by methods which, although difficult, were virtually exact: perfectly conducting particles suspended in a perfect dielectric fluid; perfect dielectric particles suspended in a perfect dielectric fluid. The goal in these theoretical studies was to give an expssion for the threshold field strength for pearl-chain formation in order to evaluate its biological significance

Interactions between Electromagnetic Fields ( Book )
1 edition published in 1985 in English and held by 1 WorldCat member library worldwide
We applied for this grant to support a workshop at Erice, Italy. This workshop has been commonly called 'Erice School' and the main subject of this workshop is the interaction of electromagnetic fields with biological cells and molecules. The grant from ONR enabled us to invite American scientists to participants in this workshop and deliver scientific papers. The duration of the Erice School was ten days. Therefore, we had sufficient time to discuss the problems of electromagnetic radiations. Vigorous discussions took place during official sessions and during private conversations. The participants of this workshop are mostly those who have been active in the research on bioelectromagnetics, but there are some numbers of speakers who discussed the basic electrical and magnetic properties of polyelectrolytes, biological membranes and tissue. The workshop was unique in that there were participants with a variety of training backgrounds. This enabled us to exchange the information between applied scientists and basic scientists. Also, active exchanges of opinions took place between biological scientists and physical scientists

The time constants of pearl-chain formation ( Book )
1 edition published in 1960 in English and held by 1 WorldCat member library worldwide
The time constants involved in the pearl-chain formation are of the order of a second for the radius of 1 micron, and they are porportional to the cube of the radius. The time constants are not strongly dependent on the field intensity when it is small, and they are inversely proportional to the square of the field intensity when it is large. The transition between the two regions occurs near the threshold. For particles of several microns or of larger sizes, the time constants become as large as hundreds of seconds, and consequently there exists a danger of observing erroneous threshold values in experimental works. The pulsed applied field is as effective as is expected from its r.m.s. value for usual radar systems. The hazards due to heat become pronounced before the field intensity is large enough for the pearl-chain to form if the particle size is less han 10 micron. The phenomenon of pearl-chain formation was considered of no biological significance in the area of microwave hazards due to radar exposure. (Author)
Microwaves and Thermoregulation: Historical Intrtoduction ( Book )
1 edition published in 1981 in English and held by 1 WorldCat member library worldwide
Building models of the thermoregulatory system and gaining insight about how RF energy is absorbed by the human body have been two distinct disciplines with very little cross-fertilization for several decades. Their historical developments have much in common. In both cases, models of the human body were introduced which were initially very simple. These models were eventually replaced by increasing complex models providing ever-increasing predictive capability. I will first outline the history of thermal RF-tolerance and of thermoregulation and then conclude with a survey of recent attempts to merge these two areas. The models to be considered are: (1) RF and MW energy deposition, (2) human thermoregulation, and (3) thermoregulation and microwaves
