background: the extremely low-frequency electromagnetic field (elf-emf), mainly emitted by electric transmission lines and household electronic appliances, is becoming a worldwide health risk. it is imperative to investigate the biological impacts of elf-emf and to identify products that are resistant to the radiation from 50 hz elf-emf. in this study, we investigated the biological impacts of ...

background: rapidly increasing possibilities of exposure to environmental extremely low-frequency electromagnetic fields (elf-emf) have become a topic of worldwide investigation. epidemiological and laboratory studies suggest that exposure to elf-emf may increase cancer risk therefore assessment of chromosomal damage in various cell lines might be of predictive value for future risk estimation....

the effect of electrical currents by different modalities on wound healing has been experimented. in this study a survey of the literature shows different results, and the mechanisms of action have not been elucidated for certain. the aim of this study was to compare the results obtained from low voltage-square wave stimulation of different frequencies. results show that the healing period for ...

Desktop publishing has changed the production of books in recent years. For the first time the author has the possibilityof preparing and influencing the design of his text. A publisher will not always be happy about this, especially if the author does not want to follow the strict rules of the publishing house which it may have followed for years. But everybody should welcome this new method o...

In certain applications the use of stable compensators greatly simplifies controller testing and implementation. Unfortunately, standard LQG theory, as well as mixednorm H2/H, theory, may yield compensators that are unstable. The problem of synthesizing stable stabilizing controllers has been of interest for many years [14], and a variety of techniques have been proposed based on modifications ...

introduction: neural stimulation is a promising new technology for the treatment of medically-intractable seizures.  transcranial magnetic stimulation (tms) is a simple, non-invasive, low cost technique which is widely used in neurophysiology. in a few studies that have been performed at different frequencies the therapeutic effects of this technique were not obvious. repetition of low frequenc...
