Yarmolyuk N. Biorhythmological approach to analyzing of the reactions of planarians Dugesia tigrina to the effect of weak electromagnetic shielding

The thesis investigated the influence of weak electromagnetic shielding, an alternating magnetic field with the frequency of 8 Hz and their combined effect on the time speed organization of regenerating and non-regenerating planarians Dugesia tigrina. Electromagnetic factors don't change the dynamics of non-regenerating planarians speed, but rearrange the rhythm of various ranges. Weak days-long electromagnetic shielding smoothes over rhythmic processes of different ranges of non-regenerating planarians speed and desynchronosis. Changes of ultradian rhythm are the most expressed; they increase with the rise of duration of screening. Changes of infradian and ultradian rhythm under the influence of an alternating magnetic field of low frequency were in spectrum shortening of the periods due to reducing of the longest rhythms, reducing the amplitude of selected rhythms and phase shift. Akrofaza rhythm shifts rapidly in circadian rhythms and the amplitude is also reduced. Under the combined effect of electromagnetic shielding and the alternating magnetic field with the frequency of 8 Hz to non-regenerating planarians with the increased number of impacts up to 14 correction of screen ultradian rhythm changes is identified. It is reflected in the reconstruction of the spectra and phase relations; however, the amplitude of the detected rhythms is still reduced. Weak electromagnetic forces increase the velocity of regenerating planarians and change its infradian rhythm, the transformation of which is less pronounced than in case of non-regenerating planarians.
