Microwave therapy and muscle blood flow in man

D. R. McNiven, D. J. Wyper · 1976

Microwave therapy produced a highly significant increase in muscle blood flow in all subjects, raising the mean from 2.9 ml/100g/min at rest to 11.4 ml/100g/min at the end of application. Short wave diathermy, infra red irradiation, pulsed electromagnetic therapy, ice and massage produced no significant effect on muscle blood flow. No significant correlation was found between athletic fitness and blood flow or between resting blood flow and the time delay before the increase, which varied from 5 to 12 minutes.

Microwave leakage indication

Kashyap SC, Wong JY, Dunn JG · 1976

The first system uses a liquid crystal film backed by microwave absorbing material that changes color from black to blue when exposed to microwaves. The color change occurs at a power density determined by the film's operating temperature and the absorbing material's properties. Normal room temperature changes have negligible effect on the strip, and hot vapor effects can be minimized with thermal insulation backing. The second system uses RF detector diodes distributed on a transmission line connected to a voltmeter, indicating the maximum RF field along the slot. With diodes spaced at 2λ intervals on a 1.0-inch wide, 12-inch long slot line, the device indicates when leakage exceeds a permissible level.

The parameter called transference is defined as the mass of solute transferred from a saturated solution under perfect sink conditions across the membrane per unit time and area multiplied by the membrane thickness. Permeability coefficients differ for each donor solvent while transference is independent of solvent unless solvent-membrane interaction occurs.

AIRCRAFT RADAR MEASUREMENTS IN THE NEAR FIELD

Richard A. Tell, Norbert N. Hankin, David E. Janes, Jr. · 1976

Researchers measured microwave exposure levels near parked commercial aircraft from weather radar installed in the nose of the aircraft on five aircraft with three radar types. Measurements were made on stationary antennas and average values of power density were calculated taking into account antenna rotation. With the antennas rotating, only one system produced a level in excess of the current OSHA-ANSI standard of 10 milliwatts per square centimeter (mW/cm2). For rotating antennas the power density decreased to less than 1 mW/cm2 at distances greater than 3.5 m (11.5 ft.) for all systems measured. The measured values agree well with values calculated from a model employing near-field gain correction factors.

An Investigation of the Use of Microwave Radiation for Pulmonary Diagnostics

P. C. PEDERSEN, C. C. JOHNSON, C. H. DURNEY, D. G. BRAGG · 1976

Researchers used a 13 cm by 13 cm applicator at 915 MHz with power levels of 50 to 100 microwatts to measure microwave reflection during human respiration. Deep breathing produced maximum amplitude and phase changes of about 1 dB and 5 degrees with the applicator on the chest and 2 dB and 10 degrees on the back. In a dog with artificially induced edema, baseline amplitude shifts followed edema progression up to 15 times normal respiratory changes, while only a small phase shift occurred. The authors concluded the technique may allow qualitative monitoring of lung water changes but not quantitative determinations or discrimination between intra- and extravascular fluid.

A review of microwaves for food processing

A. J. H. Sale · 1976

Microwave heating alone has led to few commercial successes but combined with conventional heating has greater potential and several successful processes. Successful applications include pasta drying using a combination of microwave heating with hot air that reduces drying time from about 10 hours to about half an hour, and doughnut proofing that reduces proofing time from 30-40 minutes to 4 minutes with more than twenty units installed.

A simple way to obtain a low-cost high sensitivity detector is to use an active device, especially a transistor oscillator, coupled to an antenna. The detector operates in a frequency-selective mode at low power densities and can switch to a non-selective mode at higher densities by adjusting the antenna coupling.

Light-induced fast conformational change in all-trans-retinal at low temperature

S. Georghiou · 1976

Researchers measured nanosecond fluorescence of all-trans-retinal in a non-polar matrix at 100 K. The fluorescence spectrum broadened from 113 nm to 127 nm full width at half maximum within nanoseconds after excitation, while the spectral maximum and long-wavelength portion remained unchanged.
