In the lower frequency band the conductivity of sodium chloride solutions was found to be independent of frequency. At higher frequencies between 690 and 4 320 Mc/s the refractive index, attenuation coefficient, absorption index and effective conductivity were measured for a 3-0% sodium chloride solution.

Studies on the Biological Effect of High Frequency Radio Waves (Radar)

Richard H. Follis, Jr. · 1946

Researchers exposed 13 male guinea pigs to radar radiation from an SCR 517-A unit at 10 cm wavelength and 45 kW peak output for three hours daily over 51 to 83 days. Histological examination of all tissues, including testes, revealed no abnormalities.

CONCERNING THE QUESTION OF SELECTIVE HEATING OF SMALL PARTICLES IN THE ULTRASHORT WAVE CONDENSER FIELD

H. Schaefer, H. Schwan · 1943

For the stationary case, a water-in-oil emulsion with optimum droplet conductivity at field strengths of 5–10 kv/cm produced a 60° average temperature rise in 2 mm diameter particles, making selective boiling dispersal possible. The non-stationary starting process showed a possibility of a considerable rise in relative particle temperatures above the stationary achievable high temperatures. For microscopic and colloid-dispersed dimensions, achievable temperature rises remained far below 1/1000°, limiting practical use to macroscopic systems. A medical-therapeutic usage possibility was mentioned briefly.

Zur Frage der selektiven Erhitzung kleiner Teilchen im Ultrakurzwellen-Kondensatorfeld

H. Schaefer, H. Schwan · 1943

The paper begins with an introduction addressing the problem statement and current knowledge. The main part examines spatial temperature distribution in an emulsion. It also analyzes individual droplets in a stationary state with mathematical treatment and application to water-in-oil emulsion. Further sections cover selective boiling processes in water-in-oil emulsion including mathematical treatment, experimental investigation of non-stationary temperature distribution in a model system, and applications to oil macro- and micro-systems. The paper concludes with final remarks, a summary, and literature references.

THE INVESTIGATION OF PROTEINS BY DIELECTRIC MEASUREMENTS

J. L. Oncley · 1942

The dielectric behavior of protein solutions differs from that of other electrolytes. Interactions between protein molecules affect their dielectric properties. Dipole moments play an important part in the behavior of protein solutions.
