GENERATION OF HYPERSONIC WAVES UPON IRRADIATION OF SILICON WITH LIGHT, THEIR PROPAGATION AND INFLUENCE ON LIVING ORGANISMS: COMPUTER SIMULATION AND EXPERIMENT
Abstract and keywords
Abstract (English):
This paper presents a molecular dynamics simulation of hypersonic wave propagation in liquid–solid systems such as aqueous solutions of NaCl and glass (containing Na ions); the role of waveguide properties of Na+–(H2O)n–type clusters is analyzed; the role of Na+–(H2O)n-type clusters in the propagation of hypersonic waves is discussed. The interaction between hypersound and cellular organelles was studied numerically and compared with biological experiments on seeds of spring soft wheat variety Ekada 70, in particular on the effect of this effect on their growth. hypersonic irradiation affects the biometric parameters of spring soft wheat, seed weight and yield. In this case, the time of exposure to this irradiation is of great importance. The smallest plant height in the variant with seed irradiation for 30 minutes was 71 s, and the productive bushiness was 1.8. The indices of general bushiness and the average number of normally developed stems producing grain per plant were also the best in the variant with exposure to seed material irradiation for 100 seconds, the worst in the variant of 30 minutes. From this we can conclude that hypersonic irradiation affects the biometric parameters of spring soft wheat, seed weight and yield. In this case, the time of exposure to this irradiation is of great importance. The data obtained as a result of modeling show that the water-glass interface is a channel for energy transfer from a source of hypersonic waves to a biological object.
