Researchers exposed rabbits for one minute to a constant magnetic field of 460 versts, a UHF field of wavelength 7.5 z at 30 v/m, and an SHF field of wavelength 12.5 cm with power flux density 40 m W/cm?. The constant magnetic field increased the number of EEG spindles. UHF and SHF fields caused the appearance of slow high-amplitude waves, which could be accompanied by increased spindles. Unilateral ablation of the midbrain reticular formation, posterior atrolateral thalamic nucleus, or anterior hypothalamus did not hinder these EEG responses. The authors concluded that the fields act directly on the central nervous system, not reflexively.

Researchers exposed suspensions of E. coli and B. subtilis spores to microwave energy at 2,450 MHz and conventional heating, comparing inactivation quantitatively. During transient microwave heating, E. coli showed a 6 log cycle reduction in viability, nearly identical to that predicted from conventional heating at the same time-temperature profile. B. subtilis spores heated at 100°C, in ice, and during transient heating showed identical inactivation by microwave and conventional heating.

The standard recommends a radiation protection guide of 10 mW/cm² for electromagnetic radiation from 10 MHz to 100 GHz averaged over any 0.1-hour period. The guide applies to both continuous and intermittent radiation and covers whole-body and partial-body exposure. Radiation at a power level tenfold smaller than the guide is considered to have no noticeable effect, while radiation tenfold larger is considered certainly dangerous.

Researchers trained squirrel monkeys to press a button to avoid painful stimuli preceded by flashing lights. After training, the animals received 15 minutes of electroanesthesia followed by recovery periods ranging from 5 to 40 minutes. Performance on the decision-making task was compared before and after electroanesthesia, showing that about a 30-minute recovery period was required to return to baseline performance.

The apparatus was designed around equality of the Damkohler group (rL/uC). The test organism was a 10 °'celli per ml. suspension of Salmonella genftenberg 775W, and experiments were performed at 65.6°C and one replication at 68.3°C. Lethality predictions from the model agreed with prototype measurements at the 1% significance level for a diameter scale-up of 2 and a flow-rate scale-up of 4.

Surface anodal polarization depolarizes deep pyramidal neurons while hyperpolarizing superficial elements. Surface cathodal polarization produces the opposite effects. Anodal polarization of the ventricular surface hyperpolarizes hippocampal pyramidal neurons, whereas cathodal polarization depolarizes them.

The technique was described as general, simple, and permitting fast and accurate measurement. For freshly picked samples with about 65% moisture content, the dielectric constant was measured approximately 29-7j. As samples dried out, the dielectric constant diminished to about 1.5 per g² at 8-10 GHz.
