It was found that, depending on their frequency, mechanical vibrations (MVs) can either stimulate (4 Hz) or inhibit (50 Hz) the growth and the division of the lon mutant of Escherichia coli K-12. Similar effects were observed when the MV-treated nutr

The effect of mechanical vibrations (MV) electrical conductivity of water and optical density of aqueous DNA solution. Distilled water was treated with MV of several frequencies from 3 to 5000 Hz with an intensity of 90 dB for 30 minutes. Different s

It was shown that the static magnetic field (SMF) and electromagnetic field (EMF) caused inhibition of the cell division in Escherichia coli K-12 lon mutant. The low-frequency EMF 4 Hz led to the 20% survival, but EMF at 50 Hz increased the survival

The effect of perfusate on the contractile activity of an isolated internally perfused heart of Helix pomatia was studied. The changes in heart activity induced by the switching of the perfusate stream were more pronounced in a potassium-free solutio
