USP # 6,506,148 (January 14, 2003) Nervous System Manipulation by EM Fields from Monitors Loos, Hendricus Abstract: Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near 1/2 Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when disp...

From wideband electric field records acquired using a 12-bit digitizing system with a 500-ns sampling interval, microsecond-scale pulses in different stages of cloud flashes in Florida and New Mexico are analyzed. The pulse occurrence statistics and waveshape characteristics are presented, The larger pulses tend to occur early in the flash and presumably are related to the flashinitiating break...

Analyzing the production of weakly relativistic plasma produced by microwave fields with circular polarization the electron distribution function is obtained to be non-equilibrium and anisotropic. Furthermore, it is shown that produced plasma is accelerated on the direction of propagation of microwave electric fields. The electron velocity on this direction strongly depends on electron originat...

Traditional food processing approaches like cooking, freezing, refrigeration and blanching are commonly known methods and are generally used by the people in their homes. However, in the food processing industries these techniques are combined with other processing operations with the help of several contemporary process-technology plants by using different technical prospects that are not comm...

objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats.  methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...

The term "electromagnetic fields" (EMF) is a combination of electric and magnetic fields as a diagnostic method as well as a therapeutic tool with many advantages such as ease of operation and painlessness, very controllable, which today has found wide application in regenerative medicine and also cancer treatment.  In addition to organs such as nerves, hearts, and bones that have an electrica...

It is sometimes claimed that gravitomagnetism, measured by the LAGEOS satellites using the GRACE models [Ciufolini and Pavlis 2004], that might also be detected by refining the Gravity Probe B data analysis [Muhlfelder, Keiser and Turneaure 2007], has already been observed by Lunar Laser Ranging, LLR [Murphy, Nordtvedt and Turyshev 2007]. Here we show that there are two types of gravitomagnetic...

Technological advances in ultrafast optics now allow the generation of laser pulses whose duration is as short as a few optical cycles of the electric field; furthermore, these pulses can be focused to a spot size comparable to the wavelength. These strongly focused, ultrashort laser pulses have found applications, for instance, in high-resolution microscopy, particle trapping and electron acce...

In this research, a 3-D mathematical model is developed for simulating electromagnetic continuous removal of inclusions from molten metals. The model includes the computation of electromagnetic force field and fluid flow in the presence of electromagnetic forces. The results of flow field together with electromagnetic force field were further used for calculating the trajectory of inc...
