VIBRATIONAL SPECTRA OF IN VIVO BIOLOGICAL SYSTEMS

Unknown authors

The paper examines the detailed spectroscopic properties of the Fröhlich model for in vivo biological systems in the millimeter-wave and far-infrared region. Three spectroscopic observables are analyzed: emissivity, Raman-intensity ratio, and attenuation function. The attenuation function is invariant with changes in the photon distribution function and provides no information about Bose condensation onset. The Raman-intensity ratio approaches unity in the high photon occupation limit and is insensitive to the non-linear parameter in that limit. A single emissivity term for the lowest-frequency mode shows behavior distinctly different from blackbody terms and continues to discriminate between equilibrium and non-equilibrium cases independently of frequency.

Early Developmental Deficits in Rats Following In-utero Exposure to 500 μW/cm², 2450-MHz Microwaves

Unknown authors

Researchers exposed eight pregnant rats to 500 uW/cm² 2450 MHz microwaves for 20 hours a day during the first 19 days of gestation. Exposed litters had seven times more neonatal deaths than controls, and pups weighed less on day 7 and opened their eyes one day later. Prenatally exposed females showed accelerated growth between 40 and 60 days of age and maintained a 10% higher body weight into adulthood.

MICROWAVE DIATHERMY TREATMENT OF THE HUMAN THIGH PART I The Experimental Measurement of the Muscle Blood Flow in the Thigh Undergoing Microwave Diathermy Treatment

redacted

Resting blood flow rates were about 2 ml/min/100 gm and maximum rates reached 32 ml/min/100 gm at depths of 1.5 cm and 3.0 cm. Microwave heating alone increased blood flow at the shallow depth of 1.5 cm. Adding surface cooling before and during heating eliminated the flow increase at the shallow depth but augmented perfusion at the deeper depth.

HIGH INTENSITY TRANSILLUMINATOR for Diagnostic and Surgical Procedures

Unknown authors

The device is used for general illumination, retinal detachment procedures, ophthalmoscopy, localization of intraocular foreign bodies and uveal tumors, gonioscopy, and goniotomy. A right angle prism can be attached to deflect the light 90°, and optional blue, green, yellow, and red narrow bandpass filters are available. The unit operates on 115 or 220 VAC, weighs 8 pounds, and the lamp lasts 200 hours at 75% intensity or 40 hours at full intensity.

Die spezifische-biologischen Wirkungen kurzer elektrischer Wellen / The specific-biological effects of short electrical waves

Tomberg, V.

The study investigated the influence of short electrical waves on living organisms at wavelengths less than 8 meters. The principal effect in both magnetic or electric fields was Joule's heat.

Researchers expressed dipole near fields using cylindrical waves for closed-form integration. They found commonly used near-field formulas can give incorrect values.

CONTROL OF ORE ACTIVATION BY DIELECTRIC METHOD

Jean-Marie THIEBAUT et al.

Researchers measured the dielectric response of sphalerite suspensions in distilled water, cupric solution, and sodium sulfate solution using a cell with a silica tank and glued electrodes from 50kHz to 50MHz. In cupric solution the solid conductivity increased by a ratio of about 2 while permittivity remained unchanged, indicating a conductive surface deposit likely of CuS. No change in solid conductivity or permittivity was observed with sodium sulfate solution, consistent with its known non-reactivity with zinc sulfide.

HOW TO ENHANCE THE PENETRATION ON MICROWAVE HYPERTHERMIA

CHANG-YING HU, SHI-CHENG LI

Researchers exposed pig muscle samples in vitro to microwave radiation with the electric field parallel and perpendicular to the muscle fibers at a power density of 700 mW/cm² for 15 minutes. At 3 cm depth the perpendicular field produced a 4°C higher temperature rise, and at 4 cm depth it produced a 2°C higher rise. Surface cooling reduced the temperature rise by about 15° at the surface and 725° at 1 cm depth, with little influence beyond 2 cm.

Environmental conditions are controlled: temperature 20–40 °C ±0.5 °C, humidity 25–65 % ±1.5 %, with air flow up to 38 L/min. The system also detects animal movement through power variations, allowing qualitative stress staging.
