Bioelectromagnetic influence on the eyes of a group of 336 subjects with various vision disorders: amblyopia, myopia and hypermetropia were investigated with high-frequency black-white and color coronal discharge, infrared thermography and visual acuity measurements. The authors have performed registration of the biggest part of electromagnetic fields – infrared and electric fields. Positive correlation with r=0.55­0.65 at a level of significance of p<0.01 was found between the temperature change (connected with vasodilation) in the influenced areas and the average change of visual acuity (visus). In the cases without correction, Student’s t-test of visus values for both eyes before and after bioelectromagnetic influence lead to t=6.0­6.7 at significance level p<0.001 and average increase of 14.5%. In the cases of refraction amblyopia, for the difference in both eyes with correction,t was equal to 6.7­7.1 at significance level p<0.001 and the average visus was increased and was 25.5%. Concerning the correlation between the temperature difference and the effective width of the high-frequency corona discharge, it was found that r=6.0­6.7 at significance level p<0.001.The dependence of the bio effect on the stage of the vision disorder (light, medium, heavy) was investigated. A distinct regularity was found with a coefficient of correlation r ranging from ­0,35 to ­0,45 at significance level p<0,001 that the influence efficiency was highest in light disorders and lowest in heavy disorders. Single-factor dispersion analysis was performed concerning age-related dependence of the healing effect in cases of visual disorders. For the three groups: 4­-10, 11-­21 and 22­-49 years of age, we found that F=4,4­-4,6 at significance level p<0.01 corresponding to higher healing results at younger ages.

Rapid thermal annealing (RTA) of ion-implanted Si is important for device fabrication. The defect structures of 2.5, 4.0, and 6.0 MeV As-implanted silicon irradiated to fluences of 2E14, 4E14, and 6E14, respectively, have been analyzed by electron diffraction both before and after RTA at 1100°C for 10 seconds. At such high fluences and energies the implanted As ions change the Si from crystalline to amorphous. Three distinct amorphous regions emerge due to the three implantation energies used (Fig. 1). The amorphous regions are separated from each other by crystalline Si (marked L1, L2, and L3 in Fig. 1) which contains a high concentration of small defect clusters. The small defect clusters were similar to what had been determined earlier as being amorphous zones since their contrast was principally of the structure-factor type that arises due to the difference in extinction distance between the matrix and damage regions.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.
